Description

Technical Field

[0001] The present application relates to the technical field of laser cutting, and in particular to a laser cutting device for metal pipe bending. Background Art

[0002] Laser cutting is a processing technology that uses a high-power density laser beam to cut materials. When the laser beam irradiates the surface of the material, the surface temperature of the material rises sharply, causing the material to melt, vaporize or decompose. As the laser beam moves across the material, the molten material or metal debris is blown away with the help of a high-speed airflow or inert gas coaxial with the laser beam, thereby forming an incision and completing the cutting of the material.

[0003] Common metal bent pipes include straight pipes that are interconnected and perpendicular to each other at both ends, and an arc pipe in the middle. Currently, a commonly used laser cutting equipment for cutting both ends of metal bent pipes includes a frame, a workbench and a laser cutting head. The metal bent pipe is movably installed on the workbench, and the laser cutting head is arranged perpendicular to the axis of the straight pipe section of the metal bent pipe.

[0004] When cutting, the metal elbow must first be fixed on the workbench, and the straight section at one end of the metal elbow must be located in the cutting area. Then, the laser beam must be perpendicular to the axis of the straight section of the metal elbow, and the laser beam must be rotated around one end of the metal elbow. The molten material and metal debris are blown away by the ejected high-speed argon gas flow to achieve cutting of the first end side of the metal elbow. Then, the second end side of the metal elbow is rotated to the cutting area and the metal elbow is cut. After the cutting is completed, burrs are likely to form on the inner wall of the cut portion of the metal elbow. In order to ensure the molding quality of the metal elbow and reduce the uneven stress distribution caused by the sudden drop in temperature of the metal elbow, the technicians must first place the metal elbow in the storage area, wait for the metal elbow to cool to room temperature, and finally grind and deburr the cut portion.

[0005] Regarding the above-mentioned related technologies, if the laser cutting step and the burr grinding step are carried out separately, the waiting time of the cooling step and the transportation cost will be increased, and the production efficiency will be low. If the laser cutting step and the burr grinding step are carried out simultaneously, during cutting, the laser beam causes the local area of ​​the metal elbow to heat up rapidly, thereby forming a significant temperature gradient. This temperature gradient will cause thermal stress inside the material. Then, in the process of burr grinding in the area where the thermal stress is concentrated, the thermal stress inside the metal elbow is easily unbalanced, which can easily cause its deformation or even cracking, and reduce the quality of burr grinding. Therefore, this needs to be improved. Summary of the invention

[0006] In order to facilitate the simultaneous execution of laser cutting and burr grinding, improve the efficiency of the processing flow, and at the same time improve the quality of grinding, the present application provides a laser cutting device for metal pipe bending.

[0009] The grinding assembly includes a first sliding block slidably arranged on the mounting seat, the sliding direction of the first sliding block is perpendicular to the rotation axis of the laser cutting head, a grinding wheel is rotatably arranged on the first sliding block, the grinding wheel is coaxially movably inserted into the end side of the metal bent pipe and movably fits with the inner circumferential wall of the metal bent pipe, a first power member for driving the grinding wheel to rotate is arranged on the first sliding block, and a driving member for driving the first sliding block to slide is arranged on the mounting seat;

[0010] The reversing assembly includes a sheave coaxially arranged on the fixed plate, the sheave is located on a side of the mounting seat away from the fixed plate, four groups of radial grooves are opened on the outer peripheral wall of the sheave, the four groups of radial grooves are evenly spaced along the circumference direction of the sheave, and the inner side walls of the radial grooves are connected with the end face of the sheave, and the radial grooves are arranged along the radial direction of the sheave, and a dial is rotatably arranged on the side wall of the mounting seat close to the sheave, and a cylindrical pin is provided on the dial, and the cylindrical pin is movably located in the radial groove and movably pressed against the inner side wall of the radial groove, and a limiting structure is provided on the dial to limit the rotation of the sheave when the cylindrical pin is separated from the radial groove, and a second power member for driving the dial to rotate is provided on the mounting seat;

[0011] When the first end side of the metal bent pipe rotates to correspond to the laser cutting head, the second end side is located at a side away from the grinding wheel;

[0012] When the second end side of the metal elbow needs to be cut, the reversing assembly drives the fixed disk to rotate until the second end side corresponds to the laser cutting head, and at this time the first end side corresponds to the grinding wheel.

[0013] By adopting the above technical solution, when it is necessary to cut the metal bent pipe, the second power member drives the dial to rotate until the cylindrical pin is separated from the radial groove. Due to the set limiting structure, the groove wheel is not easy to rotate at this time, thereby limiting the rotation of the fixed disk, which is convenient for the fixation of the metal bent pipe. Then the technician places a metal bent pipe heated by the preheating assembly into the installation groove, so that the first end side of the metal bent pipe is located on the side away from the grinding wheel, and the second end side is located on the side away from the laser cutting head. This is the initial position. Then the third power member drives the fixed block to slide and press against the metal bent pipe to fix the metal bent pipe.

[0014] The dial continues to rotate so that the cylindrical pin is located in a radial groove and is tightly pressed against the inner wall of the radial groove, thereby driving the groove wheel to rotate, and then driving the fixed disk to rotate until the first end side of the metal elbow rotates to correspond to the laser cutting head and the second end side is located on the side away from the grinding wheel. At this time, the cylindrical pin is separated from the radial groove, so that the fixed disk maintains a constant relative position, and then the adjustment part drives the laser cutting head to descend and approach the metal elbow, and the laser cutting head emits a laser beam and sprays an argon gas flow. Immediately afterwards, the adjustment part drives the laser cutting head to rotate around the end side of the metal elbow until the laser cutting head rotates one circle to achieve cutting of the metal elbow. Then the adjustment part drives the laser cutting head to stop rotating and rise, at which time the cylindrical pin rotates to another adjacent radial groove.

[0015] The dial continues to rotate, so that the cylindrical pin is pressed against the inner wall of the radial groove, and drives the groove wheel to rotate, thereby driving the fixed plate to rotate until the first end side of the metal bent pipe rotates to correspond to the grinding wheel, and the second end side rotates to correspond to the laser cutting head. At this time, the cylindrical pin rotates to separate from the radial groove.

[0016] The dial continues to rotate, at which time the cylindrical pin is separated from the radial groove, and the fixed disk maintains a constant relative position. At the same time, the first power member drives the grinding wheel to rotate, and the driving member drives the first sliding block to slide in the direction close to the fixed disk, thereby driving the grinding wheel to insert into the first end side of the metal bent pipe and fit with the inner circumferential wall of the metal bent pipe to achieve grinding of the first end side. At the same time, the adjustment member drives the laser cutting head to cut the second end side of the metal bent pipe, thereby achieving simultaneous laser cutting and burr grinding, reducing the transportation cost of transporting the metal bent pipe to the grinding area, and improving the efficiency of the processing flow;

[0017] At the same time, the technician places another metal bend in the installation groove at the initial position, and the corresponding third power member drives the fixing block to slide to fix the other metal bend, thereby realizing cyclic loading and improving the efficiency of the processing process;

[0018] When grinding the cut part of the metal elbow, the preheating component preheats the metal elbow, thereby reducing the uneven stress distribution caused by the uneven temperature of the metal elbow during cutting. In the subsequent grinding process, it is not easy to cause deformation or even cracking of the cut part of the metal elbow, thereby improving the quality of grinding. At the same time, the adsorption component is set to absorb and clean the metal debris generated by grinding, thereby improving the cleanliness of the processing environment, and preventing the metal debris from adhering to the metal elbow, thereby reducing the influence of the metal debris on grinding.

[0019] After the cutting of the second end side of the metal bend is completed, the adjusting member drives the laser cutting head to rise and stop rotating, and at the same time, the driving member drives the first sliding block to slide in a direction away from the fixed disk, so that the grinding wheel is separated from the first end side, and then the dial continues to rotate, so that the cylindrical pin rotates into the radial groove and abuts against the inner wall of the radial groove, thereby driving the groove wheel to rotate, and then driving the fixed disk to rotate until the cylindrical pin is separated from the radial groove. At this time, the second end side of the metal bend rotates to correspond to the grinding wheel, and the first end side is located on the side away from the laser cutting head;

[0020] At the same time, a first end side of another metal bent pipe is rotated to correspond to the laser cutting head, and a second end side is rotated to a side away from the grinding wheel.

[0021] The dial continues to rotate, at this time the cylindrical pin is separated from the radial groove, the fixed disk maintains a constant relative position, and at the same time the driving member drives the first sliding block to slide, the first power member drives the grinding wheel to rotate, so as to grind the second end side of the metal bent pipe, and at the same time the adjusting member drives the laser cutting head to cut the first end side of another metal bent pipe.

[0022] After the second end of the metal bend is polished, the metal bend is processed and the dial continues to rotate to rotate the fixed plate until the cylindrical pin is separated from the radial groove. At this time, the metal bend is in the initial position, and the first end side of the other metal bend is rotated to correspond to the grinding wheel, and the second end side is rotated to correspond to the laser cutting head. Then the technician takes out the metal bend with both ends polished to realize the unloading of the metal bend. At the same time, the technician loads the material at the initial position to realize cyclic loading and unloading and improve the efficiency of the processing flow.

[0023] Optionally, the driving member includes a guide wheel coaxially arranged on the dial, the guide wheel is located on a side of the mounting seat away from the dial, a guide groove is provided on a side wall of the guide wheel away from the mounting seat, the guide groove includes a first guide groove and a second guide groove connected end to end, the first guide groove and the second guide groove are both in an arc shape coaxial with the guide wheel, the diameter of the first guide groove is larger than the diameter of the second guide groove, the connection between the first guide groove and the second guide groove is smoothly transitioned, and a guide column is provided on the first sliding block, the guide column is located in the guide groove and movably pressed against the inner side wall of the guide groove;

[0024] When the guide post slides from the first guide groove to the second guide groove, the first sliding block slides toward the fixed plate;

[0025] When the guide post slides from the second guide groove to the first guide groove, the first sliding block slides in a direction away from the fixed plate.

[0026] By adopting the above technical solution, after the end side cutting of the metal bent pipe is completed, the dial continues to rotate, at this time the cylindrical pin is separated from the radial groove, the fixed plate maintains a constant relative position, and at the same time the dial drives the guide wheel to rotate, so that the guide column and the inner wall of the guide groove are movably pressed against each other, and the guide column slides from the first guide groove into the second guide groove. Since the diameter of the first guide groove is larger than the diameter of the second guide groove, the guide column slides in the direction close to the fixed plate, driving the first sliding block box to slide in the direction close to the fixed plate, thereby realizing the grinding of burrs at the cutting part of the metal bent pipe.

[0027] After grinding is completed, the dial continues to rotate until the cylindrical pin is located in the radial groove. At this time, the guide column is located in the first guide groove, and the grinding wheel is separated from the metal bent pipe. When the dial continues to rotate, the cylindrical pin is pressed against the inner wall of the radial groove and drives the fixed plate to rotate. The grinding wheel is not easy to hinder the rotation of the fixed plate and the metal bent pipe, which is convenient for the next grinding.

[0028] Through the above solution, the periodic rotation of the fixed disk and the periodic sliding of the first sliding block are coordinated through the mechanical structure, thereby improving the stability during operation, improving the efficiency of the grinding process, and saving power sources.

[0029] Optionally, the adsorption component includes an absorption cover arranged on the first sliding block, the grinding wheel is located in the absorption cover, the absorption cover is movably fitted with the end side of the metal bent pipe, a collection box connected to the absorption cover is provided on the frame, a filter is provided in the collection box, a first air pump is provided on the collection box, and a detection component for detecting the gas in the collection box is also provided on the frame.

[0030] By adopting the above technical solution, when grinding the end side of the metal bent pipe, the grinding wheel is inserted into the metal bent pipe. At this time, the absorption cover fits with the end side of the metal bent pipe, making it difficult for metal debris after grinding to adhere to the metal bent pipe and leak out, thereby reducing the impact of metal debris on grinding.

[0031] At the same time, the first air pump inhales air, and sucks the gas from the other end of the metal elbow into the collection box, and sucks the metal elbow and metal debris in the absorption cover together, and filters the metal debris through the set filter net to achieve the collection of metal debris, thereby improving the cleanliness of the processing environment and facilitating centralized cleaning and recycling by technical personnel. At this time, the flowing gas lowers the temperature of the metal elbow grinding point, reduces the uneven stress distribution caused by uneven temperature of the metal elbow during cutting, and further improves the grinding quality. At the same time, the gas in the collection box is detected by the detection component.

[0032] Optionally, the detection assembly includes a transparent observation tube arranged on the frame, a detection electrode powered by electricity is arranged in the observation tube, the observation tube is connected to the collection box, a second air pump is arranged between the observation tube and the collection box, a video monitoring module for monitoring the observation tube is arranged on the frame, a protective cover is also arranged on the frame, the observation tube, the detection electrode and the video monitoring module are all located in the protective cover, a loading and unloading assembly for loading and unloading the metal bent pipe is arranged on the frame, and the video monitoring module is electrically connected to the loading and unloading assembly;

[0033] When the grinding wheel grinds the first end side of the metal elbow and the laser cutting head cuts the second end side, the detection electrode energizes the gas in the observation tube, and the video monitoring module detects that the observation tube emits blue-purple light, and then the video monitoring module issues a loading and unloading instruction to the loading and unloading assembly;

[0034] When the grinding wheel grinds the second end side of the metal bent pipe and the laser cutting head cuts the first end side of another metal bent pipe, the detection electrode energizes the gas in the observation tube, and the video monitoring module detects that there is no obvious color light in the observation tube, and the video monitoring module does not issue any instructions to the loading and unloading assembly.

[0035] By adopting the above technical solution, when one end side of the metal bent pipe is polished, the second air pump sucks the gas in the collection box into the observation tube, and the energized detection electrode energizes the gas. When the video monitoring module detects a blue-purple light in the observation tube, it indicates that there is a large amount of argon in the energized gas, that is, the second end side of the metal bent pipe is being cut. At this time, the other metal bent pipe is in the initial position, and both ends have been cut and polished. Then the video monitoring module drives the loading and unloading assembly to unload the metal bent pipes that have been cut and polished at both ends, and then load them.

[0036] When the video monitoring module detects that there is no obvious colored light in the observation tube, it means that the argon content in the powered gas is low, that is, the laser cutting head is cutting another metal bend. At this time, the video monitoring module does not issue instructions to the loading and unloading components, thereby realizing automatic loading and unloading and improving the efficiency of the processing process.

[0037] When detecting the position of metal bends, photoelectric sensors are usually used. When the equipment is running, laser radiation is likely to reach the photosensitive element of the photoelectric sensor, causing the quality of the signal output by the photoelectric sensor to decrease. At the same time, thermal radiation generated by cutting is likely to cause the temperature of the internal components of the sensor to rise. Metal debris generated during cutting and grinding is likely to interfere with the sensor's signal reception, reducing the sensor's detection accuracy and stability, thereby affecting the operation of the equipment. Therefore, gas detection is used to detect the position of the metal bend. At this time, the observation tube and video monitoring module are all away from the laser cutting head area. At the same time, a protective cover is set up to reduce the interference of laser radiation, thermal radiation and metal debris generated during processing on the observation tube and video monitoring module, thereby improving the accuracy of detection.

[0038] Optionally, the loading and unloading assembly includes a feeding piece arranged on the frame and a feeding belt arranged on the frame, the feeding belt is located on a side of the fixed disk away from the grinding wheel, the mounting seat is provided with a clamping piece for clamping the end side of the metal bent pipe, the mounting seat is also provided with a transfer piece for transferring the metal bent pipe, the transfer piece is located between the feeding belt and the fixed disk, the feeding piece transfers the unprocessed metal bent pipe to the top of the transfer piece, and the transfer piece corresponds to one of the fixed disk, the feeding piece and the feeding belt;

[0039] The transfer member includes a center block rotatably arranged on the mounting seat, the rotation axis of the center block is horizontally arranged and perpendicular to the rotation axis of the laser cutting head, the clamping member is arranged on the center block, and a fourth power member for driving the center block to rotate is provided on the rotating shaft of the center block, and the fourth power member and the third power member are both electrically connected to the video monitoring module.

[0040] By adopting the above technical solution, when the end side of the metal bent pipe rotates to correspond to the grinding wheel, the first power part drives the grinding wheel to rotate, and at the same time the first sliding block slides to insert the grinding wheel into the metal bent pipe, thereby realizing the grinding of the end side of the metal bent pipe. At this time, the center block corresponds to the fixed disk, and the clamping part clamps the end side of the other metal bent pipe away from the grinding wheel.

[0041] When the video monitoring module detects that there is no obvious colored light in the observation tube, the clamping member and the second end side of the other metal bent pipe are in a clamping state, and the laser cutting head is cutting the first end side of the other metal bent pipe. At this time, the video monitoring module does not issue instructions to the third power member and the fourth power member.

[0042] When the video monitoring module detects a blue-purple light in the observation tube, the other metal bend is in the initial position and both end sides are processed. The clamping piece and the end side of the processed metal bend are in a clamping state. The video monitoring module drives the third power piece corresponding to the clamping piece to work, driving the fixed block to slide and separate from the processed metal bend. Then the video monitoring module drives the fourth power piece to work, driving the center block to rotate to correspond to the unloading belt. At this time, the metal bend rotates synchronously and separates from the installation groove, and the metal bend is located on the unloading belt. At this time, the clamping piece is separated from the processed metal bend, and the unloading belt transfers the processed metal bend to the storage area, realizing the automatic unloading of the metal bend and improving the efficiency of the unloading process.

[0043] At the same time, the feeding piece transports the unprocessed metal bent pipe to the top of the center block, and then the fourth power piece drives the center block to rotate in the opposite direction to correspond to the feeding piece. At this time, the clamping piece clamps the end side of the unprocessed metal bent pipe, and then the center block continues to rotate in the opposite direction to correspond to the fixed plate. At this time, the unprocessed metal bent pipe is located in the installation groove at the initial position, and then the video monitoring module drives the third power piece corresponding to the unprocessed metal bent pipe to work, driving the fixed block to slide and press against the unprocessed metal bent pipe, thereby fixing the unprocessed metal bent pipe, thereby realizing the automatic loading of the metal bent pipe and improving the efficiency of the loading process.

[0044] Optionally, a second sliding block is slidably provided on the mounting seat, the second sliding block is arranged opposite to the first sliding block, the center block is rotatably provided on the second sliding block, the clamping member includes a clamping disk provided on the center block, the clamping disk and the end side of the metal bent pipe are movably coaxially arranged, a clamping block is rotatably provided on the clamping disk, the clamping blocks are provided with a plurality of groups, and the plurality of groups of clamping blocks are evenly spaced along the circumference direction of the clamping disk, the clamping block is movably pressed against the outer peripheral wall of the end side of the metal bent pipe, a connecting block is fixed to one end of the clamping block close to its rotating shaft, and the connecting block There is an angle between the clamping block and the connecting block, and a connecting rod is rotatably provided at one end of the connecting block away from the clamping block. The end of the connecting rod away from the clamping block is rotatably connected to the center block. A sliding rod is provided on the side wall of the clamping disk close to the center block. The sliding rod slides through the center block, and the sliding direction of the sliding rod is perpendicular to the rotation axis of the center block. An elastic member is provided on the side wall of the clamping disk close to the sliding rod. The elastic member always makes the clamping disk slide in the direction away from the center block. A sliding member for adjusting the sliding of the sliding rod is also provided on the mounting seat.

[0045] By adopting the above technical scheme, when the processed metal bent pipe is located in the initial position, the center block corresponds to the fixed disk. Due to the action of the elastic member, the clamping block is in a clamping state at this time, and then the second sliding block slides in the direction close to the fixed disk, driving the center block and the clamping disk to move in the direction close to the fixed disk, so that the end side of the metal bent pipe is located between the three groups of clamping blocks, and the clamping block is tightly pressed against the outer peripheral wall of the metal bent pipe to achieve clamping of the end side of the metal bent pipe. At this time, a gap is left between the clamping disk and the end side of the metal bent pipe, which is convenient for subsequent clamping of the unprocessed metal bent pipe.

[0046] When the center block rotates to correspond to the unloading belt, the metal bent pipe is located on the unloading belt. At this time, the sliding part causes the sliding rod to slide, and drives the clamping plate to move toward the center block, and drives the connecting rod and the connecting block to rotate, so that the end of the clamping block away from the connecting block rotates in the direction away from the metal bent pipe. At this time, the clamping block is separated from the outer peripheral wall of the metal bent pipe, thereby loosening the metal bent pipe, and then the unloading belt transports the metal bent pipe to the storage area.

[0047] When the center block rotates in the opposite direction, the sliding piece causes the sliding rod to slide, and drives the clamping plate to move away from the center block and close to the unprocessed metal bend, so that the end of the clamping block away from the connecting block rotates toward the direction close to the metal bend until the center block corresponds to the feeding piece. At this time, the clamping block is pressed against the outer peripheral wall of the unprocessed metal bend, so that the clamping block clamps the end side of the unprocessed metal bend.

[0048] When the center block continues to rotate in the opposite direction, the sliding member maintains a constant relative position between the sliding rod and the center block, thereby maintaining the clamping block on the end side of the unprocessed metal bend until the center block rotates to correspond to the fixed disk. At this time, the unprocessed metal bend is located in the mounting groove at the initial position, thereby realizing the loading of the metal bend.

[0049] Then the second sliding block slides away from the fixed disk, so that the clamping block is separated from the end side of the metal bend. When the fixed disk and the metal bend rotate subsequently, the clamping block is not likely to hinder the rotation of the unprocessed metal bend.

[0050] Through the above technical solution, the clamping block can clamp the processed and unprocessed metal bent pipes in turn, simplifying the clamping structure of loading and unloading materials, improving the stability of the clamping structure of loading and unloading materials, and facilitating maintenance.

[0051] Optionally, a second rack is provided on the second sliding block, a first rack is provided on the first sliding block, a synchronous gear is rotatably provided on the mounting seat, the first rack and the second rack are both meshed with the synchronous gear, and the first rack and the second rack are respectively located on opposite sides of the synchronous gear.

[0052] By adopting the above technical solution, when the dial rotates and the cylindrical pin is separated from the radial groove, the fixed disk maintains a constant relative position, and the first sliding block slides in the direction close to the fixed disk, so that the grinding wheel grinds the metal bent pipe. At the same time, the first sliding block drives the first rack to slide synchronously, drives the synchronous gear to rotate, and thus drives the second sliding block to slide in the direction close to the fixed disk, thereby clamping the end side of the metal bent pipe away from the grinding wheel.

[0053] By clamping the end of the metal bent pipe, the metal bent pipe is not easy to move, thereby improving the stability of the fixed plate, thereby improving the stability during cutting and grinding, and improving the quality of cutting and grinding.

[0054] When the dial is rotated until the cylindrical pin is located in another radial groove, the first sliding block slides away from the fixed disk. At this time, the grinding wheel is separated from the metal bent pipe. At the same time, the first sliding block drives the first rack to slide synchronously, driving the synchronous gear to rotate, thereby driving the second sliding block to slide away from the fixed disk, thereby realizing the separation of the clamping block and the metal bent pipe.

[0055] The coordinated cooperation of the periodic sliding of the second sliding block and the periodic rotation of the fixed disk is achieved through the mechanical structure, thereby improving the stability of clamping the metal bent pipe and saving power source.

[0056] Optionally, the sliding member includes a clamping wheel provided on the second sliding block, the clamping wheel is located between the second sliding block and the center block, a clamping column is slidably provided on the sliding rod, the outer peripheral wall of the clamping column is movably clamped against the outer peripheral wall of the clamping wheel, the clamping wheel includes a first abutment block, a second abutment block and a third abutment block fixedly connected to each other, the first abutment block is cylindrical and coaxially arranged with the rotation axis of the center block, the second abutment block is fixed on the outer peripheral wall of the first abutment block and is in the shape of a smoothly transitioned protrusion, the second abutment block is located on the side of the first abutment block close to the fixed disk, and the third abutment block is in the shape of an arc. and being coaxially fixed on the first abutment block, the diameter of the third abutment block being larger than the diameter of the first abutment block, the convex ends of the third abutment block and the second abutment block being smoothly transitioned, the third abutment block and the second abutment block being stepped, and the thickness of the third abutment block being smaller than the thickness of the second abutment block, the side walls of the third abutment block and the abutment column being close to each other are movably pressed against each other, an inclined sliding groove is provided on the side wall of the third abutment block close to the abutment column, the abutment column is movably pressed against the inclined side of the sliding groove, and an end of the abutment column away from the third abutment block is provided with a reset member that enables the abutment column to slide toward the direction close to the abutment wheel;

[0057] When the abutting column slides and abuts against the first abutting block, the clamping block maintains a clamping state;

[0058] When the abutting column slides to the protruding end of the second abutting block, the abutting column and the side walls of the third abutting block that are close to each other are separated. At this time, the abutting column and the outer peripheral wall of the third abutting block are pressed tightly, the center block corresponds to the blanking belt, and the clamping block is in an open state;

[0059] When the abutting column rotates to be separated from the third abutting block, the abutting column abuts against the outer peripheral wall of the first abutting block, the central block corresponds to the feeding piece, and the clamping block maintains a clamping state.

[0060] By adopting the above technical solution, when the center block corresponds to the fixed disk, the clamping column is located on the side of the first abutting block away from the second abutting block. Due to the elastic member, the clamping disk is driven to move away from the center block, and the clamping column is moved toward the center block. At this time, the outer peripheral wall of the clamping column is tightly pressed against the outer peripheral wall of the first abutting block, and the clamping block is in a clamping state.

[0061] When the center block rotates to correspond to the unloading belt, the clamping column rotates to be tightly pressed against the raised end of the second abutment block. At this time, the second abutment block causes the clamping column to move away from the center block and drives the sliding rod to slide, causing the clamping plate to move toward the center block, so that the clamping block is in an open state, thereby loosening the metal bent pipe.

[0062] At the same time, during the rotation of the clamping column, the outer peripheral wall of the clamping column is pressed against the outer peripheral wall of the first abutment block. Since the first abutment block is cylindrical, the clamping block maintains a clamping state at this time, and the clamping column continues to rotate, so that the clamping column is pressed against the inclined side of the sliding groove and slides along the sliding groove, so that the clamping column and the side walls of the third abutment block that are close to each other are pressed against each other, until the clamping column rotates to press against the raised end of the second abutment block. At this time, the reset part drives the clamping column to slide in the direction close to the clamping wheel, so that the outer peripheral wall of the clamping column is pressed against the outer peripheral wall of the third abutment block.

[0063] When the center block rotates in the opposite direction to correspond to the feeding piece, the clamping column rotates to separate from the third abutment block. At this time, the elastic member drives the clamping disk to move away from the center block until the clamping block is in a clamping state and clamps the end side of the unprocessed metal bent pipe. At this time, the outer peripheral wall of the clamping column is tightly pressed against the outer peripheral wall of the first abutment block.

[0064] When the center block continues to rotate in the opposite direction to correspond to the fixed disk, the clamping column rotates to the side of the first abutment block away from the second abutment block. Since the first abutment block is cylindrical, the clamping block maintains a clamping state at this time, so that the clamping block stably clamps the unprocessed metal bend pipe and rotates it to the installation groove in the initial position, thereby realizing the loading of the metal bend pipe.

[0065] Through the above technical solution, the clamping block can be automatically switched between the clamping and opening states at different positions, which facilitates the loading and unloading of metal bent pipes, improves the loading and unloading efficiency, and saves power sources.

[0066] Optionally, the feeding member includes a feeding box arranged on the frame, the feeding box is located on the top side of the second sliding block, and a first sliding cavity and a second sliding cavity are provided on the feeding box, the first sliding cavity and the second sliding cavity are arranged alternately, and the top end of the first sliding cavity is connected with the bottom end of the second sliding cavity, the center block is movably located directly below the first sliding cavity, and the unprocessed metal bent pipes are stacked up and down in the second sliding cavity, and loading ports for rotating the metal bent pipes are provided on the two opposite inner walls of the feeding box, and a pushing member is provided on the frame to push the unprocessed metal bent pipe from the second sliding cavity into the first sliding cavity, and when the unprocessed metal bent pipe is located in the first sliding cavity, one end of the unprocessed metal bent pipe protrudes from the bottom wall of the feeding box.

[0067] By adopting the above technical solution, when the two end sides of a metal bent pipe are cut and polished respectively, the two ends of the other metal bent pipe are processed. At this time, the second sliding block slides toward the fixed plate until the center block is located directly below the first sliding cavity, and the clamping block clamps the processed metal bent pipe.

[0068] Then the fourth power member drives the central block to rotate. Since the unprocessed metal bent pipe is located in the second sliding cavity and a loading port for the metal bent pipe to rotate is provided on the inner wall of the feeding box, it is not easy to hinder the rotation of the processed metal bent pipe until the central block corresponds to the unloading belt. At this time, the pushing member causes the unprocessed metal bent pipe at the bottom of the second sliding cavity to slide from the second sliding cavity into the first sliding cavity, which is convenient for the subsequent clamping of the unprocessed metal bent pipe. At the same time, the next unprocessed metal bent pipe falls to the bottom of the second sliding cavity due to gravity, which is convenient for the next loading.

[0069] When the center block rotates in the opposite direction to correspond to the first sliding cavity, the clamping block clamps the end of the unprocessed metal bent pipe protruding from the bottom wall of the feeding box, and then the center block continues to rotate in the opposite direction, so that the unprocessed metal bent pipe is transferred out of the feeding box at the loading port until the center block corresponds to the fixed plate, thereby realizing the loading of the unprocessed metal bent pipe and realizing the automatic feeding of the unprocessed metal bent pipe, which is suitable for subsequent loading and improves the efficiency of the loading process.

[0070] Optionally, the preheating assembly includes a heating wire disposed in the feeding box, and the heating wire is wound inside the side wall of the feeding box.

[0071] By adopting the above technical solution, the heating wire preheats the unprocessed metal bend in the second sliding cavity, thereby reducing the uneven stress distribution caused by the uneven temperature of the metal bend during subsequent cutting. In the subsequent grinding process, it is not easy to cause deformation or even cracking at the cutting point of the metal bend, thereby improving the quality of grinding and facilitating the subsequent delivery of the heated unprocessed metal bend to the top of the center block, thereby reducing energy loss.

[0072] In summary, the present application includes at least one of the following beneficial technical effects:

[0073] 1. Through the set frame, mounting seat, fixed plate, fixed block, third power member, laser cutting head, adjusting member, preheating assembly, reversing assembly and grinding assembly, during processing, the technician places the metal elbow heated by the preheating assembly in the mounting groove, and drives the fixed block to slide and press against the metal elbow through the third power member to fix the metal elbow. Since the preheating assembly preheats the metal elbow, the uneven stress distribution caused by the uneven temperature of the metal elbow during cutting is reduced. In the subsequent grinding process, it is not easy to cause deformation or even cracking of the cutting part of the metal elbow, thereby improving the quality of grinding;

[0074] Then the reversing component drives the fixed plate to rotate to one end of the metal bend corresponding to the laser cutting head, the adjusting part drives the laser cutting head to cut one end side of the metal bend, and the grinding component grinds the metal bend synchronously, so as to realize the synchronous operation of laser cutting and burr grinding, reduce the transportation cost of transporting the metal bend to the grinding area, and improve the efficiency of the processing flow;

[0075] When one metal elbow is being cut and polished at the same time, the two ends of another metal elbow have been processed. At this time, the technicians unload and load the metal elbow, thus realizing cyclic loading and unloading and improving the efficiency of the processing process;

[0076] 2. Through the adsorption component, observation tube, detection electrode, second air pump, video monitoring module, protective cover and loading and unloading component, when the metal elbow is being polished, the adsorption component sucks the gas from the side away from the metal elbow being polished, and collects the metal debris after polishing, so as to improve the cleanliness of the processing environment, facilitate the centralized cleaning and recycling of technical personnel, and make it difficult for the metal debris after polishing to leak out and adhere to the metal elbow, thereby reducing the influence of the metal debris on polishing. At the same time, the flowing gas reduces the temperature of the metal elbow polishing place, reduces the uneven stress distribution caused by the uneven temperature of the metal elbow during polishing, and further improves the quality of polishing;

[0077] At the same time, the second air pump sucks the gas sucked by the adsorption component into the observation tube, and the detection electrode energizes the gas in the observation tube. When the video monitoring module detects that a blue-purple light is emitted in the observation tube, it indicates that there is a large amount of argon in the energized gas, that is, the first end side of the metal bend is being cut, and at the same time, both ends of the other metal bend have been cut and polished. At this time, the video monitoring module drives the loading and unloading components to unload and load the metal bends that have been cut and polished at both ends. When the video monitoring module detects that there is no obvious color light in the observation tube, it indicates that the argon content in the energized gas is low, that is, the laser cutting head is cutting another metal bend. At this time, the video monitoring module does not issue instructions to the loading and unloading components, thereby realizing automatic loading and unloading and improving the efficiency of the processing flow. At the same time, the observation tube and the video monitoring module are all far away from the processing area, and the protective cover is set to reduce the interference of laser radiation, thermal radiation and metal debris generated during the processing on the observation tube and the video monitoring module, thereby improving the accuracy of detection;

[0078] 3. Through the provided groove wheel, dial, cylindrical pin, limiting structure, first power piece, second power piece, first sliding block, grinding wheel, guide wheel and guide column, during processing, the second power piece drives the dial to rotate, so that the cylindrical pin is pressed against the inner wall of the radial groove, and drives the groove wheel to rotate, thereby driving the fixed plate to rotate, until one end side of the metal elbow rotates to correspond to the grinding wheel, at which time the cylindrical pin is separated from the radial groove, and due to the setting of the limiting structure, the dial continues to rotate, the fixed plate maintains a constant relative position, the dial drives the guide wheel to rotate, the guide column slides in the guide groove, and drives the first A sliding block slides in a direction close to the fixed disk, so that the grinding wheel is inserted into one end side of the metal bent pipe, and at the same time, the first power member drives the grinding wheel to rotate, so that the grinding wheel grinds the metal bent pipe until the cylindrical pin rotates to be located in another radial groove. At this time, the guide column and the first sliding block slide in a direction away from the fixed disk, and the grinding wheel is separated from the metal bent pipe, so that the grinding wheel is not easy to hinder the rotation of the fixed disk. The periodic rotation of the fixed disk and the periodic sliding of the first sliding block are coordinated through the mechanical structure, thereby improving the stability of the grinding process, improving the efficiency of the processing flow, and saving power source at the same time;

[0079] 4. By setting the second sliding block, the central block, the fourth power piece, the clamping piece, the second sliding block, the sliding piece, the feeding piece, the unloading belt, the first rack, the second rack and the synchronous gear, when the first sliding block slides in the direction close to the fixed disk, it drives the first rack to slide, drives the synchronous gear to rotate, thereby drives the second rack and the second sliding block to slide synchronously, so that the clamping piece clamps the metal bent pipe. When the video monitoring module detects the blue-purple light in the observation tube, the video monitoring module drives the third power piece corresponding to the clamped metal bent pipe to work, drives the fixed block to slide and separate from the metal bent pipe, and then the video monitoring module drives the fourth power piece to work, drives the central block to rotate to correspond to the unloading belt, so that the metal bent pipe is located in the unloading position. The unprocessed metal bend is placed in the installation groove, and then the video monitoring module drives the corresponding third power part to work, driving the fixed block to slide and press against the unprocessed metal bend, so as to fix the unprocessed metal bend, thereby realizing the automatic loading and unloading of the metal bend, and at the same time, the mechanical structure is used to coordinate the clamping of the metal bend by the clamping part and the periodic rotation of the fixed disk, thereby improving the stability of loading and unloading, and saving power source.

DETAILED DESCRIPTION

[0087] The following is combined with Figure 1-6 This application is described in further detail.

[0088] The present application embodiment discloses a laser cutting device for metal pipe bending. Figure 1 A laser cutting device for a metal pipe bend includes a frame 1 fixed horizontally on the ground and a mounting seat 18 fixed on the frame 1. The top of the mounting seat 18 is rotatably connected with a fixed disk 11. The rotating axis of the fixed disk 11 is arranged in the vertical direction. A mounting groove 12 is provided on the top of the fixed disk 11. The metal pipe bend is installed in the mounting groove 12, and both ends of the metal pipe bend protrude from the fixed disk 11. The mounting groove 12 is provided with two groups. The two groups of mounting grooves 12 are evenly spaced around the rotating axial direction of the fixed disk 11. The top of the fixed disk 11 is also slidably connected with two groups of fixing blocks 13. The two groups of fixing blocks 13 correspond to the two groups of fixing grooves one by one. The fixing blocks 13 and the metal pipe bend are away from the axis of the fixed disk 11. The outer peripheral wall is movably pressed against, the sliding direction of the fixed block 13 is horizontally arranged and points to the axis of the fixed disk 11, and the fixed disk 11 is provided with a third power member 14 for driving the fixed block 13 to slide. In this application, the third power member 14 is set as an electric push rod, and the frame 1 is connected to a laser cutting head 15 for lifting and rotating. It should be noted that the auxiliary gas used in laser cutting in this application is argon. The laser cutting head 15 is always arranged toward the outer peripheral wall of the metal bent pipe. The frame 1 is also provided with an adjusting member 16 for driving the laser cutting head 15 to lift and rotate. The rotation axis of the laser cutting head 15 is horizontally arranged and moves in unison with the axis of the end side of the metal bent pipe. The frame 1 is also provided with a preheating component 7 for preheating the metal bent pipe.

[0089] In order to carry out laser cutting and burr grinding simultaneously and improve the efficiency of the processing process, a grinding component 2 is provided on the mounting seat 18. Figure 1 and Figure 3 The grinding assembly 2 includes a first sliding block 21 slidably connected to the top of the mounting seat 18, and the sliding direction of the sliding block is perpendicular to the rotation axis of the laser cutting head 15. A grinding wheel 22 is rotatably connected to the first sliding block 21. The grinding wheel 22 is coaxially movably inserted into the end side of the metal bent pipe and movably fits against the inner circumferential wall of the metal bent pipe. A first power member 23 for driving the grinding wheel 22 to rotate is also fixed on the first sliding block 21. In the present application, the first power member 23 is set as a servo motor.

[0090] In order to drive the fixed disk 11 to rotate and rotate the end side of the metal bend to correspond to the laser cutting head 15, a reversing assembly 3 is provided on the mounting seat 18. Figure 2The reversing assembly 3 includes a groove wheel 31 coaxially fixed on the fixed disk 11, and the groove wheel 31 is located at the bottom side of the mounting seat 18. Four groups of radial grooves 32 are opened on the outer peripheral wall of the groove wheel 31. The four groups of radial grooves 32 are evenly spaced along the circumference direction of the groove wheel 31, and the inner side wall of the radial groove 32 is connected to the end face of the groove wheel 31. The radial groove 32 is arranged along the radial direction of the groove wheel 31. The bottom of the mounting seat 18 is rotatably connected with a dial 33. The rotation axis of the dial 33 is parallel to the rotation axis of the fixed disk 11. A cylindrical pin 34 is fixed on the dial 33. The cylindrical pin 34 is movably located in the radial groove 32 and movably pressed against the inner side wall of the radial groove 32. A driving dial 33 is fixed on the mounting seat 18 to rotate. The second power member 35 is configured as a servo motor in the present application. In order to limit the rotation of the groove wheel 31 when the cylindrical pin 34 is separated from the radial groove 32, the limiting structure includes a limiting wheel 361 coaxially fixed on the dial 33. The limiting wheel 361 and the cylindrical pin 34 have arc-shaped notches at corresponding positions. Four groups of locking grooves 362 are provided on the outer peripheral wall of the groove wheel 31. The four groups of locking grooves 362 are evenly spaced along the circumference direction of the groove wheel 31. Each group of locking grooves 362 is located between two adjacent radial grooves 32. The inner side wall of the locking groove 362 is connected to the end face of the groove wheel 31, and the outer peripheral wall of the limiting wheel 361 is movably fitted with the side wall of the locking groove 362.

[0091] When the metal bend needs to be cut, the second power member 35 drives the dial 33 to rotate until the cylindrical pin 34 is separated from the radial groove 32. At this time, the outer peripheral wall of the limiting wheel 361 fits with the side wall of the locking groove 362, making it difficult for the groove wheel 31 to rotate, thereby limiting the rotation of the fixed disk 11 and facilitating the fixation of the metal bend. Then the technician places a metal bend heated by the preheating assembly 7 in the mounting groove 12, so that the first end side of the metal bend is located on the side away from the grinding wheel 22, and the second end side is located on the side away from the laser cutting head 15, which is the initial position. Then the third power member 14 drives the fixing block 13 to slide and press against the metal bend to fix the metal bend.

[0092] The dial 33 continues to rotate, so that the cylindrical pin 34 is located in a radial groove 32 and is tightly pressed against the inner wall of the radial groove 32. At this time, the limiting wheel 361 is separated from the locking groove 362, so that the limiting wheel 361 is not easy to hinder the rotation of the groove wheel 31, so that the dial 33 drives the groove wheel 31 to rotate, and then drives the fixed disk 11 to rotate until the first end side of the metal bend rotates to the position of the laser cutting head 15, and the second end side is located on the side away from the grinding wheel 22. At this time, the cylindrical pin 34 is separated from the radial groove 32, so that the fixed disk 11 maintains a constant relative position, and then the adjusting member 16 drives the laser cutting head 15 to descend and approach the metal bend, and then the adjusting member 16 drives the laser cutting head 15 to rotate around the end side of the metal bend until the laser cutting head 15 rotates one circle to achieve cutting of the metal bend, and then the adjusting member 16 drives the laser cutting head 15 to rise and stop rotating, at this time, the cylindrical pin 34 rotates to another adjacent radial groove 32.

[0093] The dial 33 continues to rotate, so that the cylindrical pin 34 is pressed against the inner wall of the radial groove 32, and drives the groove wheel 31 to rotate, thereby driving the fixed plate 11 to rotate, until the first end side of the metal bend rotates to correspond to the grinding wheel 22, and the second end side of the metal bend rotates to correspond to the laser cutting head 15, at which time the cylindrical pin 34 rotates to separate from the radial groove 32.

[0094] Then the dial 33 continues to rotate, at which time the cylindrical pin 34 is separated from the radial groove 32, and the outer wall of the limiting wheel 361 is fitted with the side wall of the locking groove 362, so that the fixed disk 11 maintains a constant relative position, and at the same time the first power member 23 drives the grinding wheel 22 to rotate, and the driving member 24 drives the first sliding block 21 to slide in the direction close to the fixed disk 11, so that the grinding wheel 22 is inserted into the first end side of the metal bend and fits with the inner wall of the metal bend to achieve grinding of the first end side, and at the same time the adjusting member 16 drives the laser cutting head 15 to cut the second end side of the metal bend, thereby achieving simultaneous laser cutting and burr grinding, reducing the transportation cost of transporting the metal bend to the grinding area, and improving the efficiency of the processing flow.

[0095] At the same time, the technician places another metal bend in the installation groove 12 at the initial position, and the corresponding third power member 14 drives the fixing block 13 to slide, thereby fixing the other metal bend and loading the metal bend.

[0096] When grinding the cut part of the metal bend, the preheating component 7 preheats the metal bend, thereby reducing the uneven stress distribution caused by the uneven temperature of the metal bend during cutting. In the subsequent grinding process, it is not easy to cause deformation or even cracking of the cut part of the metal bend, thereby improving the quality of grinding.

[0097] After the second end side of the metal elbow is cut, the adjusting member 16 drives the laser cutting head 15 to rise and stop rotating. At the same time, the driving member 24 drives the first sliding block 21 to slide away from the fixed disk 11, so that the grinding wheel 22 is separated from the first end side, so that the grinding wheel 22 is not easy to hinder the subsequent rotation of the fixed disk 11.

[0098] After cutting and grinding are completed, the dial 33 continues to rotate and drives the fixed plate 11 to rotate. The first end side of the metal bent pipe rotates to the side away from the laser cutting head 15, and the second end side rotates to correspond to the grinding wheel 22. At the same time, the first end side of another metal bent pipe rotates to correspond to the laser cutting head 15, and the second end side rotates to the side away from the grinding wheel 22.

[0099] The dial 33 continues to rotate, and the fixed disk 11 maintains a constant relative position. At the same time, the driving member 24 drives the first sliding block 21 to slide, and the first power member 23 drives the grinding wheel 22 to rotate, so as to grind the second end side of the metal bend. At the same time, the adjusting member 16 drives the laser cutting head 15 to cut the first end side of another metal bend, thereby completing the processing of the two end sides of the metal bend.

[0100] After cutting and grinding are completed, the dial 33 continues to rotate and drives the fixed plate 11 to rotate, so that the processed metal bend rotates to the initial position. At the same time, the first end side of the other metal bend rotates to correspond to the grinding wheel 22, and the second end side rotates to correspond to the laser cutting head 15.

[0101] The dial 33 continues to rotate, and the fixed disk 11 maintains a constant relative position. At the same time, the driving member 24 drives the first sliding block 21 to slide, and the first power member 23 drives the grinding wheel 22 to rotate, so as to grind the first end side of another metal bent pipe. At the same time, the adjusting member 16 drives the laser cutting head 15 to cut the second end side of another metal bent pipe. At the same time, the technician takes out the processed metal bent pipe to realize the unloading of the metal bent pipe. At the same time, the technician loads the material at the initial position to realize cyclic loading and unloading, thereby improving the efficiency of the processing flow.

[0102] Further, in order to drive the first sliding block 21 to slide and allow the grinding head to be inserted into the metal elbow, a driving member 24 is provided on the mounting seat 18. Figure 3The driving member 24 includes a guide wheel 241 coaxially fixed on the dial 33, the guide wheel 241 is located on the top side of the mounting seat 18, and the guide wheel 241 is located on the side of the first sliding block 21 close to the fixed disk 11, and a guide groove is opened on the top of the guide wheel 241, and the guide groove includes a first guide groove 242 and a second guide groove 243 connected end to end, and the first guide groove and the second guide groove are both in an arc shape coaxial with the guide wheel 241, and the diameter of the first guide groove 242 is greater than the diameter of the second guide groove 243, and the connection between the first guide groove 242 and the second guide groove 243 is smoothly transitioned, and a guide column 244 is fixed on the first sliding block 21, and the guide column 244 is located in the guide groove and movably pressed against the inner side wall of the guide groove.

[0103] After the cutting of one end side of the metal elbow is completed, the dial 33 continues to rotate. At this time, the cylindrical pin 34 is separated from the radial groove 32, and the fixed disk 11 maintains a constant relative position. At the same time, the dial 33 drives the guide wheel 241 to rotate, so that the guide column 244 is movably pressed against the inner wall of the guide groove, and the guide column 244 slides from the first guide groove 242 into the second guide groove 243. Since the diameter of the first guide groove 242 is larger than the diameter of the second guide groove 243, the guide column 244 slides in the direction close to the fixed disk 11, driving the first sliding block 21 box to slide in the direction close to the fixed disk 11, thereby realizing the grinding of burrs on the cutting part of the metal elbow.

[0104] After the grinding is completed, the dial 33 continues to rotate until the cylindrical pin 34 is located in the radial groove 32. At this time, the guide column 244 is located in the first guide groove 242, and the grinding wheel 22 is separated from the metal bent pipe. When the dial 33 continues to rotate, the cylindrical pin 34 is pressed against the inner wall of the radial groove 32 and drives the fixed plate 11 to rotate, the grinding wheel 22 is not easy to hinder the rotation of the fixed plate 11 and the metal bent pipe, which is convenient for the next grinding.

[0105] Through the above scheme, the periodic rotation of the fixed disk 11 and the periodic sliding of the first sliding block 21 are coordinated through the mechanical structure, thereby achieving coordinated cooperation between grinding and reversing of metal bending pipes, improving stability during operation, improving the efficiency of the grinding process, and saving power sources.

[0106] Furthermore, in order to absorb and clean the metal debris generated by grinding, so that the technicians can centrally clean and recycle it, and at the same time improve the cleanliness of the environment, an adsorption component 4 is provided on the mounting seat 18, referring to Figure 1 and Figure 3 The adsorption assembly 4 includes an absorption cover 41 fixed on the first sliding block 21, the absorption cover 41 is movably fitted with the end side of the metal elbow, the grinding wheel 22 is located in the absorption cover 41, and a collection box 42 connected to the absorption cover 41 is fixed on the frame 1, a filter is provided in the collection box 42, and a first air pump 43 is provided on the collection box 42.

[0107] In order to detect the gas in the collection box 42, a detection component 5 is provided on the frame 1. Figure 1 and Figure 3 The detection component 5 includes a transparent observation tube 51 fixed on the frame 1, and an energized detection electrode 52 is fixed in the observation tube 51. In the present application, the detection electrode 52 is a tungsten wire. The observation tube 51 is connected to the collection box 42, and a second air pump 53 is fixed between the observation tube 51 and the collection box 42. A video monitoring module 54 for monitoring the observation tube 51 is fixed on the frame 1. A protective cover 55 is also fixed on the frame 1. The observation tube 51, the detection electrode 52 and the video detection module are all located in the protective cover 55. A loading and unloading component 6 for loading and unloading metal bent pipes is provided on the frame 1, and the video monitoring module 54 is electrically connected to the loading and unloading component 6.

[0108] After the metal bend is rotated to correspond to the grinding wheel 22 and the fixed plate 11 maintains a constant relative position, the first sliding block 21 slides to insert the grinding wheel 22 into the metal bend to achieve grinding of the metal bend. At this time, the absorption cover 41 fits with the end side of the metal bend, making it difficult for metal debris after grinding to adhere to the metal bend and leak out, thereby reducing the influence of metal debris on grinding.

[0109] At the same time, the first air pump 43 inhales air, and sucks the gas from the other end of the metal elbow into the collection box 42, and sucks the metal elbow and metal debris in the absorption cover 41 together, and filters the metal debris through the set filter net to achieve the collection of metal debris, improve the cleanliness of the processing environment, and facilitate technical personnel to centrally clean and recycle. At this time, the flowing gas reduces the temperature of the metal elbow grinding point, reduces the uneven stress distribution caused by uneven temperature of the metal elbow during grinding, and further improves the quality of grinding.

[0110] At the same time, the second air pump 53 sucks the gas in the collection box 42 into the observation tube 51, and enables the energized detection electrode 52 to energize the gas. When the video monitoring module 54 detects a blue-purple light in the observation tube 51, it indicates that there is a large amount of argon in the energized gas, that is, the other end of the metal bend is being cut. At this time, the other metal bend is in the initial position, and both ends have been cut and polished. At this time, the video monitoring module 54 drives the loading and unloading assembly 6 to unload and load the metal bends that have been cut and polished at both ends.

[0111] When the video monitoring module 54 detects that there is no obvious colored light in the observation tube 51, it means that the argon content in the energized gas is low, that is, the laser cutting head 15 is cutting another metal bent pipe. At this time, the video monitoring module 54 does not issue instructions to the loading and unloading component 6, thereby realizing automatic loading and unloading and improving the efficiency of the processing process.

[0112] During gas detection, the observation tube 51 and the video monitoring module 54 are kept away from the laser cutting head 15 area. At the same time, the protective cover 55 is set to reduce the interference of laser radiation, thermal radiation and metal debris generated during the processing on the observation tube 51 and the video monitoring module 54, thereby improving the accuracy of detection and further improving the stability of loading and unloading.

[0113] Further, in order to load and unload the metal bend, refer to Figure 1 and Figure 3 The loading and unloading assembly 6 includes a feeding piece 65 arranged on the frame 1 and a feeding belt 67 fixed to the frame 1. The feeding belt 67 is located on the side of the fixed disk 11 away from the grinding wheel 22. The transmission direction of the feeding belt 67 is consistent with the sliding direction of the first sliding block 21. The mounting seat 18 is provided with a clamping piece 62 for clamping the end side of the metal bent pipe.

An elastic member 626 is provided on the side wall of the clamping disk 621 close to the sliding rod 625. The elastic member 626 always makes the clamping disk 621 slide in the direction away from the center block 631. In the present application, the elastic member 626 is a clamping spring.

[0117] In order to realize the automatic switching of the clamping block 622 between the clamping state and the opening state, and to facilitate the loading and unloading of the metal bend pipe, a sliding member 64 is provided on the mounting seat 18, Figure 4 and Figure 5The sliding member 64 includes a clamping wheel fixed on the second sliding block 61, the clamping wheel is located between the second sliding block 61 and the center block 631, and the sliding member is connected with a clamping column 641. The outer peripheral wall of the clamping column 641 is movably clamped on the outer peripheral wall of the clamping wheel. The clamping wheel includes a first abutting block 642, a second abutting block 643 and a third abutting block 644 which are fixedly connected to each other. The first abutting block 642 is cylindrical and is coaxially arranged with the rotation axis of the center block 631. The second abutting block 643 is fixed on the outer peripheral wall of the first abutting block 642 and is in the shape of a smoothly transitioned protrusion. The second abutting block 643 is located on the side of the first abutting block 642 close to the fixed disk 11. The third abutting block 644 is in an arc shape and is coaxially fixed to the first abutting block 6 42, the diameter of the third abutment block 644 is larger than the diameter of the first abutment block 642, the third abutment block 644 smoothly transitions to the raised end of the second abutment block 643, the third abutment block 644 and the first abutment block 642 are stepped, and the thickness of the third abutment block 644 is smaller than the thickness of the second low-level block, the third abutment block 644 and the side walls of the clamping column 641 close to each other are movably pressed together, an inclined sliding groove 645 is provided on the side wall of the third abutment block 644 close to the clamping column 641, the clamping column 641 and the inclined side of the sliding groove 645 are movably pressed together, and a reset member 646 is fixed to the end of the clamping column 641 away from the third abutment block 644 for sliding the clamping column 641 toward the direction of the clamping wheel, and the reset member 646 in the present application is a reset spring.

[0118] When the fixed disk 11 rotates to one end side of the metal bent pipe corresponding to the grinding wheel 22, the center block 631 corresponds to the fixed disk 11, and the elastic member 626 causes the clamping disk 621 to slide in the direction away from the center block 631, and drives the connecting rod 624 and the connecting block 623 to rotate. Since there is an angle between the connecting block 623 and the clamping block 622, the end of the connecting block 623 away from the clamping block 622 is located between the rotating shaft of the clamping block 622 and the axis of the clamping disk 621, so that the end of the clamping block 622 away from the connecting block 623 rotates in the direction close to the outer peripheral wall of the other metal bent pipe until the clamping disk 621 drives the sliding rod 625 and the clamping column 641 to slide, so that the outer peripheral wall of the clamping column 641 is pressed against the outer peripheral wall of the first abutting block 642, so that the clamping disk 621 and the center block 631 maintain a constant relative position, and the clamping block 622 is in a clamping state.

[0119] Then the first sliding block 21 slides in the direction close to the fixed disk 11 to achieve grinding of the metal bent pipe. At the same time, the first sliding block 21 drives the first rack 211 to slide, drives the synchronous gear 17 to rotate, and drives the second sliding block 61 to slide, thereby driving the center block 631 and the clamping disk 621 to slide in the direction close to the fixed disk 11, so that the inclined side of the clamping block 622 is pressed against the metal bent pipe, and the end of the clamping block 622 away from the connecting block 623 is rotated in the direction away from the outer peripheral wall of the metal bent pipe until the inclined side of the clamping block 622 is separated from the metal bent pipe, so that the side wall of the clamping block 622 close to the axis of the clamping disk 621 is pressed against the outer periphery of the metal bent pipe, thereby clamping the metal bent pipe. At this time, a gap is left between the clamping disk 621 and the end side of the metal bent pipe, which is convenient for subsequent clamping of the unprocessed metal bent pipe.

[0120] When the video monitoring module 54 detects that a blue-purple light is emitted from the observation tube 51, it indicates that the laser cutting head 15 is cutting the other end side of the metal bend corresponding to the grinding wheel 22, and the metal bend corresponding to the clamping block 622 is in the initial position at this time, and both end sides are cut and ground. At this time, the video monitoring module 54 drives the third power member 14 corresponding to the processed metal bend to work, driving the fixed block 13 to slide and separate from the metal bend, and then the video monitoring module 54 drives the fourth power member 632 to work, driving the center block 631 to rotate to the position aligned with the unloading belt. 67 corresponds to the metal bent pipe, which rotates synchronously and separates from the mounting groove 12, and places the metal bent pipe on the unloading belt 67. At this time, the clamping column 641 rotates to abut against the raised end of the second abutting block 643, so that the clamping column 641 moves away from the center block 631, and drives the sliding rod 625 to slide, so that the clamping plate 621 moves toward the direction close to the center block 631, and the clamping block 622 is in an open state, thereby releasing the metal bent pipe. Then the unloading belt 67 transfers the metal bent pipe to the storage area, realizing the automatic unloading of the metal bent pipe and improving the efficiency of the unloading process.

[0121] During the rotation of the clamping column 641, the outer peripheral wall of the clamping column 641 is pressed against the outer peripheral wall of the first abutting block 642. Since the first abutting block 642 is cylindrical, the clamping disk 621 and the center block 631 maintain a constant relative position. At this time, the clamping block 622 maintains a clamping state, and the clamping column 641 continues to rotate, so that the clamping column 641 is pressed against the inclined side of the sliding groove 645 and slides along the sliding groove 645, so that the clamping column 641 and the side walls of the third abutting block 644 that are close to each other are pressed against each other, until the clamping column 641 rotates to press against the raised end of the second abutting block. At this time, the reset member 646 drives the clamping column 641 to slide in the direction close to the clamping wheel, so that the outer peripheral wall of the clamping column 641 is pressed against the outer peripheral wall of the third abutting block 644.

[0122] At the same time, the feeding piece 65 transports the unprocessed metal bent pipe to the top of the center block 631, and then the fourth power piece 632 drives the center block 631 to rotate in the opposite direction to correspond to the feeding piece 65. At this time, the clamping column 641 rotates to separate from the third abutting block 644. The elastic piece 626 drives the clamping disk 621 to move away from the center block 631, so that the clamping block 622 is in a clamping state and clamps the end side of the unprocessed metal bent pipe. At the same time, the outer peripheral wall of the clamping column 641 is tightly pressed against the outer peripheral wall of the first abutting block 642.

[0123] Then the fourth power member 632 drives the center block 631 to continue to rotate in the opposite direction. At this time, the clamping column 641 rotates to the side of the first abutment block 642 away from the second abutment block 643. Since the first abutment block 642 is cylindrical, the clamping block 622 maintains the clamping of the unprocessed metal hose until the center block 631 rotates to correspond to the fixed disk 11. At this time, the unprocessed metal bend is located in the installation groove 12 at the initial position, and then the video monitoring module 54 drives the third power member 14 corresponding to the unprocessed metal bend to work, driving the fixed block 13 to slide and press against the unprocessed metal bend, thereby fixing the unprocessed metal bend, thereby realizing the automatic loading of the metal bend and improving the efficiency of the loading process.

[0124] After the cutting and grinding is completed, the first sliding block 21 and the first rack 211 slide synchronously in the direction away from the fixed disk 11, and drive the synchronous gear 17 to rotate, thereby driving the second rack 611 and the second sliding block 61 to slide synchronously, so that the center block 631 and the clamping disk 621 slide synchronously in the direction away from the fixed disk 11, thereby separating the clamping block 622 from the unprocessed metal bend, so that the clamping block 622 is not easy to hinder the subsequent rotation of the fixed disk 11.

[0125] Through the above technical scheme, the periodic sliding of the second sliding block 61 and the periodic rotation of the fixed disk 11 are coordinated through the mechanical structure to realize the clamping / separation of the metal bent pipe on the fixed disk 11, and the stability of clamping the metal bent pipe is improved. When loading, the clamping block 622 is used to clamp the processed and unprocessed metal bent pipes in turn, which simplifies the clamping structure of loading and unloading, improves the stability of the clamping structure of loading and unloading, and facilitates maintenance by technical personnel. At the same time, the clamping block 622 is automatically switched between the clamping or opening state in different positions, realizing the automatic loading and unloading of metal bent pipes, improving the efficiency of loading and unloading, and improving the efficiency of the processing flow, saving power sources.

[0126] Further, see Figure 6The feeding member 65 includes a feeding box 651 fixed on the frame 1, and the feeding box 651 is located on the top side of the second sliding block 61. The feeding box 651 is provided with a first sliding cavity 652 and a second sliding cavity 653. The first sliding cavity 652 and the second sliding cavity 653 are arranged alternately, and the top of the first sliding cavity 652 is connected to the bottom of the second sliding cavity 653. The central block 631 is movably located directly below the first sliding cavity 652. The unprocessed metal bent pipes are stacked up and down and placed in the second sliding cavity 653, and one end side of the unprocessed metal bent pipes is arranged horizontally, and the other end side is arranged vertically. Feeding ports 654 for rotating the metal bent pipes are provided on the opposite side walls of the feeding box 651. The feeding box 651 is rotatably connected to the feeding port 654. The baffle 655 is movably pressed against the outer peripheral wall of the horizontal straight pipe section of the unprocessed metal bent pipe. A limiting torsion spring 656 is provided at the rotating shaft of the baffle 655 to limit The torsion spring 656 always keeps the baffle 655 in a vertical state. In order to push the unprocessed metal bend from the second slide cavity 653 into the first slide cavity 652, a push piece 66 is provided on the frame 1. When the unprocessed metal bend is located in the first slide cavity 652, the push piece 66 of the unprocessed metal bend includes a push block 661 slidably connected to the feed box 651. The push block 661 is movably protruded from the inner bottom wall of the second slide cavity 653. The top side of 661 is pointed, and the inclined side of the push block 661 is movably pressed against the outer peripheral wall of the horizontal straight pipe section of the metal elbow at the bottom in the second sliding cavity 653. A push rod 662 is fixed on the push block 661, and a push cam 663 is rotatably connected to the second sliding block 61. The push cam 663 is fixedly connected to the rotating shaft of the center block 631, and the end of the push rod 662 away from the push block 661 is movably pressed against the outer peripheral wall of the push cam 663.

[0127] The preheating assembly 7 includes a heating wire 71 fixed in the feeding box 651 , and the heating wire 71 is wound inside the side wall of the feeding box 651 .

[0128] When the same metal elbow is being cut and polished, the cutting and polishing of both ends of another metal elbow is completed, and the second sliding block 61 slides toward the direction close to the fixed plate 11. At this time, the center block 631 is located directly below the first sliding cavity 652, and the clamping block 622 clamps the processed metal elbow. At the same time, the heating wire 71 heats the unprocessed metal elbow in the second sliding cavity 653, so that the heated unprocessed metal elbow can be sent to the top of the center block 631 to reduce energy loss. After preheating, the uneven stress distribution caused by the uneven temperature of the metal elbow during subsequent cutting is reduced. In the subsequent polishing process, it is not easy to cause deformation or even cracking at the cutting position of the metal elbow, thereby improving the quality of polishing.

[0129] Then the fourth power member 632 drives the central block 631 to rotate, and a loading port 654 for the metal bend to rotate is provided on the inner wall of the feeding box 651, and a baffle 655 is rotatably connected to the unloading port, so that the baffle 655 and the feeding box 651 are not easy to hinder the rotation of the metal bend after processing, until the central block 631 corresponds to the unloading belt 67, at which time the convex end of the push cam 663 and the end of the push rod 662 away from the push block 661 are tightly pressed, so that the push rod 662 and the push block 661 move upward synchronously, so that the inclined side of the push block 661 is aligned with the second slide cavity 6 The outer peripheral wall of the horizontal straight pipe section at the bottom of the metal bend in 53 is movably pressed against, and the unprocessed metal bend slides from the second slide cavity 653 into the first slide cavity 652. At the same time, the limiting torsion spring 656 keeps the baffle 655 vertical and fits with the outer peripheral wall of the metal bend, so that the unprocessed metal bend is not easy to slide out of the feeding box 651 from the loading port 654, which is convenient for the subsequent clamping block 622 to clamp the unprocessed metal bend. At the same time, the next unprocessed metal bend falls to the bottom of the second slide cavity 653 due to gravity, and presses against the inclined side of the push block 661, which is convenient for the next feeding.

[0130] When the center block 631 rotates in the opposite direction to correspond to the first sliding cavity 652, the raised end of the pushing cam 663 is separated from the pushing rod 662. At this time, the pushing block 661 drops due to gravity, so that the next unprocessed metal bend is aligned with the inner bottom wall of the second sliding cavity 653, which is convenient for feeding. The clamping block 622 clamps the end of the unprocessed metal bend protruding from the bottom wall of the feeding box 651, and then the center block 631 continues to rotate in the opposite direction. The outer peripheral wall of the unprocessed metal bend is pressed against the baffle 655 close to the clamping disk 621, and drives the baffle 655 to rotate, so that the unprocessed metal bend is turned out from the loading port 654 until the center block 631 corresponds to the fixed disk 11. At this time, the unprocessed metal bend is located in the mounting groove 12, so that the loading of the unprocessed metal bend is realized, the automatic feeding of the unprocessed metal bend is realized, and the efficiency of the loading process is improved.

[0131] The implementation principle of the laser cutting device for metal bent pipes in the embodiment of the present application is as follows: when working, the second power member 35 works to drive the dial 33 to rotate, so as to realize the periodic rotation of the fixed disk 11. When the fixed disk 11 keeps a constant relative position, the adjustment member 16 drives the laser cutting head 15 to cut the end side of the metal bent pipe. At the same time, the dial 33 drives the guide wheel 241 to rotate, drives the guide column 244 to slide with the first sliding block 21, and the first power member 23 drives the grinding wheel 22 to rotate, so that the grinding wheel 22 is inserted into one end of the metal bent pipe. , and grinds the metal elbow. At the same time, the absorption cover 41 is fitted with the end side of the metal elbow. The first air pump 43 inhales air and sucks the gas into the collection box 42 from the end away from the grinding position of the metal elbow, and sucks the metal debris generated by the grinding together to collect and clean the metal debris. At the same time, the second air pump 53 sucks the gas in the collection box 42 into the observation tube 51, energizes the gas through the detection electrode 52, and monitors the observation tube 51 through the set video monitoring module 54 to detect the gas in the collection box 42.

[0132] At the same time, the first sliding block 21 drives the first rack 211 to slide, drives the synchronous wheel to rotate, drives the second rack 611 to slide, and thus drives the second sliding block 61 to slide, so that the center block 631 and the clamping plate 621 move synchronously, and the inclined side of the clamping block 622 is pressed against the metal bent pipe, thereby driving the clamping block 622 to rotate until the side wall of the clamping block 622 close to the axis of the clamping plate 621 is pressed against the outer peripheral wall of the metal bent pipe, thereby clamping the metal bent pipe.

[0133] When one end of the metal bend corresponds to the grinding wheel 22 and the other end corresponds to the laser cutting head 15, and one end of the other metal bend is located on the side away from the grinding wheel 22 and the other end is located at the end away from the laser cutting head 15, the video monitoring module 54 detects that blue-purple light is emitted from the observation tube 51, and the video monitoring module 54 drives the third power member 14 corresponding to the clamping block 622 to work, driving the fixed block 13 to slide and separate from the metal bend corresponding to the clamping block 622, and then the video monitoring module 54 drives the fourth power member 14 to work, driving the central block 631 to rotate to correspond to the unloading belt 67, so that the metal bend Located on the unloading belt 67, at this time, the clamping column 641 and the second abutting block 643 are pressed against each other, so that the clamping column 641 and the sliding rod 625 slide, and the clamping plate 621 slides, driving the connecting rod 624 and the connecting block 623 to rotate, thereby rotating the clamping block 622, so that the clamping block 622 releases the metal bent pipe, and the unloading belt 67 transfers the metal bent pipe to the storage area to realize the unloading of the metal bent pipe. At the same time, the pushing cam 663 presses against the pushing rod 662, so that the pushing block 661 presses against the unprocessed metal bent pipe heated by the heating wire 71 in the second sliding cavity 653, so that the unprocessed metal bent pipe slides into the first sliding cavity 652.

[0134] Then the fourth power member 632 drives the central block 631 to rotate in the opposite direction to correspond to the feeding box 651, and the elastic member 626 is set to move the clamping plate 621. At this time, the clamping column 641 is separated from the third slider and abuts against the first abutment block 642 to achieve clamping of the unprocessed metal bend pipe. Then the central block 631 continues to rotate so that the unprocessed metal bend pipe is located in the installation groove 12. At this time, the video monitoring module 54 drives the third power member 14 to work, so that the fixed block 13 presses against the unprocessed metal bend pipe to achieve the loading of the metal bend pipe.

[0135] When one end of the metal bent pipe corresponds to the grinding wheel 22 and the other end is located at the end away from the laser cutting head 15, and one end of another metal bent pipe is located on the side away from the grinding wheel 22 and the other end corresponds to the laser cutting head 15, the video monitoring module 54 detects that there is no light of obvious color in the observation tube 51. At this time, the grinding wheel 22 grinds the metal bent pipe and the laser cutting head 15 cuts the metal bent pipe. The video monitoring module 54 does not issue instructions to the third power component 14 and the fourth power component 632. It works periodically in this way to realize automatic loading and unloading and automatic cutting and grinding of metal bent pipes.

[0136] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
