Description

Technical Field

[0001] This application relates to the field of intelligent manufacturing equipment industry technology, and particularly to the technical classification of feeding devices for bars, wires or strips, especially to a tube length feeding system and method for automated cutting. Background Technology

[0002] In mechanical manufacturing and process flow, pipe fitting processing is a key link; for pipe fitting processing, fast and accurate length feeding plays a vital role in work efficiency and quality.

[0003] Pipe length feeding involves feeding pipes of a specified length into automated cutting equipment so that the equipment can cut the pipes to obtain multiple pipes of the same length for subsequent manufacturing of forgings or metal pressings. Currently, pipe length feeding typically involves manually measuring the pipes, marking the locations where cutting is required, and then manually controlling the conveyor line to transport the pipes to the automated cutting equipment for cutting.

[0004] However, the inventors discovered that this method not only resulted in low efficiency in the length processing of pipe fittings, but also that manual marking of the cutting position was prone to errors, leading to low accuracy of the automated cutting equipment in cutting the pipe fittings and making it difficult to guarantee that the length of the cut pipe fittings was consistent. Summary of the Invention

[0005] This application provides a pipe length feeding system and method for automated cutting, which solves the problem that current length feeding processes not only result in low efficiency, but also that manual marking of cutting positions is prone to errors, leading to low accuracy of automated cutting equipment in cutting pipes and making it difficult to ensure consistent pipe lengths after cutting.

[0006] In a first aspect, this application provides a pipe length feeding system for automated cutting, comprising: a pipe conveying line, a clamping device, and an equipment conveying line;

[0007] The pipe fitting conveyor line is used to transport pipe fittings from the loading position to the automated cutting equipment;

[0021] The sensor is connected to the pipe pressing mechanism, and the sensor is also used to send a pipe pressing signal to the pipe pressing mechanism, which instructs the pipe pressing mechanism to press the pipe fitting onto the pipe fitting conveyor line.

[0022] In the above scheme, the pipe pressing mechanism includes: a pipe pressing support mechanism, a pipe pressing fixing plate, a pipe pressing cylinder, and a pipe pressing lever mechanism;

[0023] One end of the pipe pressing support mechanism is connected to the vertical moving mechanism, and the other end of the pipe pressing support mechanism is located above the pipe conveying line;

[0024] The bottom end of the pressure tube fixing plate is fixed on one side of the pressure tube support mechanism away from the vertical moving mechanism;

[0025] The cylinder body of the pipe-pressing cylinder is rotatably connected to the top end of the pipe-pressing fixing plate;

[0026] The tube pressing lever mechanism is fixed on the side of the tube pressing support mechanism away from the tube pressing fixing plate;

[0027] The cylinder rod of the pipe-pressing cylinder is rotatably connected to one end of the pipe-pressing lever mechanism. The end of the pipe-pressing lever mechanism away from the cylinder rod has a pressure block, which is used to press the pipe fitting tightly onto the pipe fitting conveyor line. The pipe-pressing lever mechanism is used to amplify the thrust of the pipe-pressing cylinder.

[0028] In the above scheme, the vertical moving mechanism includes: a vertical support structure, a vertical lead screw, at least one vertical guide rail, and a vertical fixing plate;

[0029] The vertical support structure is connected to one side of the pressing mechanism;

[0030] The vertical lead screw is connected to the side of the vertical support structure away from the pressing mechanism;

[0031] The vertical guide rail is movably connected to the side of the vertical support structure away from the pressing mechanism;

[0032] The upper surface of the vertical fixing plate is connected to the vertical lead screw and the vertical guide rail, and the lower surface of the vertical fixing plate is connected to the horizontal moving mechanism.

[0033] In the above scheme, the horizontal moving mechanism includes: a horizontal power mechanism and a horizontal fixed plate;

[0034] The horizontal power mechanism is fixed on the horizontal fixed plate, and the horizontal power mechanism is connected to the vertical moving mechanism;

[0035] The bottom end of the horizontal power mechanism passes through the horizontal fixed plate, and one end of the horizontal power mechanism passing through the horizontal fixed plate has a gear. The gear is connected to the equipment conveyor line, and the horizontal power mechanism is used to drive the pressing device to move on the equipment conveyor line.

[0036] In the above scheme, the horizontal moving mechanism further includes: an adjusting bar, at least one adjusting bolt, and a lubricated felt wheel;

[0037] The horizontal power mechanism is movably connected to the upper surface of the horizontal fixed plate, and the horizontal power mechanism moves on the horizontal fixed plate along the length direction perpendicular to the equipment conveyor line.

[0044] Secondly, this application provides a method for feeding pipes for automated cutting, using the aforementioned pipe feeding system, the method comprising:

[0045] Input the position parameters, feed length, and stop time into the clamping device;

[0046] The clamping device moves on the equipment conveyor line according to the position parameters and stops at the designated position on the equipment conveyor line corresponding to the position parameters.

[0047] The pipe fittings conveyor line continuously feeds the pipe fittings to the automated cutting equipment;

[0048] When the clamping device detects that the horizontal distance the pipe has been moved by the pipe conveyor line has reached the conveying length, the clamping device clamps the pipe on the pipe conveyor line, causing the pipe to stop on the pipe conveyor line.

[0049] When the clamping device clamps the pipe fitting on the pipe fitting conveyor line for the specified time, the clamping device disengages from the pipe fitting, allowing the equipment conveyor line to continue outputting the pipe fitting to the automated cutting equipment.

[0050] This application provides a pipe length feeding system and method for automated cutting. A pipe conveyor line is used to transport pipes, and an equipment conveyor line is used to move a clamping device to a designated position. When the pipe conveyor line delivers the pipe to the automated cutting equipment to a preset length, the clamping device presses the pipe onto the conveyor line. The automated cutting equipment then cuts the pipe. After the clamping device disengages, the pipe conveyor line delivers the pipe to the automated cutting equipment to the desired length. This cycle repeats continuously, stably, and efficiently, ensuring that the length of each cut pipe matches the delivery length. This improves cutting efficiency and accuracy, guaranteeing the quality of subsequent forgings or metal pressings. Attached Figure Description

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0126] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with those of this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the embodiments of this application as detailed in the appended claims.

[0127] The technical solutions of the embodiments of this application and how the technical solutions of the embodiments of this application solve the current problems are described in detail below with specific examples. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0128] Example 1:

[0129] Please see Figures 1-5 This application provides a pipe length feeding system for automated cutting, characterized in that it includes: a pipe conveying line 2, a pressing device 3, and an equipment conveying line 4;

[0130] Pipeline 2 is used to transport pipes 1 from the loading position to the automated cutting equipment;

[0131] The clamping device 3 is used to clamp the pipe fitting 1 onto the pipe fitting conveyor line 2, so that the pipe fitting 1 stops on the pipe fitting conveyor line 2;

[0132] The equipment conveyor line 4 is connected to the pressing device 3, which is used to move on the equipment conveyor line 4; wherein, the equipment conveyor line 4 is parallel to the pipe fitting conveyor line 2.

[0133] In this example, a pipeline conveyor line is set up to transport pipe fitting 1, and an equipment conveyor line 4 is set up to move the clamping device 3 to the required designated position. When the pipe fitting conveyor line 2 transports the pipe fitting 1 to the automated cutting equipment to the preset delivery length, the clamping device 3 clamps the pipe fitting 1 onto the pipe fitting conveyor line 2, and then the automated cutting equipment cuts the pipe fitting 1. After that, the clamping device 3 disengages from the pipe fitting 1, and the pipe fitting conveyor line 2 transports the pipe fitting 1 to the automated cutting equipment to the delivery length. This cycle repeats, enabling continuous, stable, and efficient delivery of the pipe fitting 1 to the automated cutting equipment. This ensures that the length of each cut pipe fitting 1 is consistent with the delivery length, improves the cutting efficiency and accuracy of the pipe fitting 1, and guarantees the product quality of subsequent forgings or metal pressings.

[0134] In a preferred embodiment, the pipe conveying line 2 includes: at least one pipe conveying roller 21;

[0135] At least one pipe fitting conveyor roller 21 is arranged sequentially in the horizontal direction.

[0136] In this example, by setting at least one pipe conveying roller 21 arranged in the horizontal direction, the technical effect of automatically transporting the pipe 1 to the automated cutting equipment is achieved. Preferably, the pipe conveying roller 21 is an electric roller.

[0137] An electric roller is a new type of drive device that integrates a motor and a reducer inside the drum body.

[0138] The electric roller integrates the motor and reducer within the roller body, significantly saving space and resulting in a more compact overall structure. Since the motor and reducer are directly connected, intermediate transmission links are reduced, improving transmission efficiency. The electric roller generates low noise during operation, contributing to a better working environment. Utilizing high-quality materials and advanced manufacturing processes, the electric roller boasts a long service life. Its transmission system is stable and reliable, operating smoothly without vibration. The electric roller can operate stably under various harsh environmental conditions, such as humid, muddy, and dusty environments. Its excellent internal sealing effectively prevents dust and moisture from entering, ensuring the normal operation of internal components.

[0139] Specifically, the pipe fitting conveying line 2 also includes: a pipe fitting support frame 22;

[0140] One end of the pipe fitting support frame 22 faces the feeding position, and the other end of the pipe fitting support frame 22 faces the automated cutting equipment;

[0141] At least one pipe fitting 1 conveying pipe is located inside the pipe fitting support frame 22 and is arranged sequentially along the length direction of the pipe fitting support frame 22. The pipe fitting 1 conveying pipe is rotatably connected to the pipe fitting support frame 22.

[0142] In this example, the pipe support frame 22 is used to position the pipe conveying roller 21 at a specified height.

[0143] Optionally, the pipe conveying roller 21 has a V-groove 23 for accommodating the pipe 1.

[0144] Optionally, the pipeline conveyor line may also include: a conveyor roller drive, a first chain and a second chain;

[0145] The conveyor roller drive device is connected to a pipe conveyor roller 21 via a first chain;

[0146] At least one pipe conveying roller 21 is sequentially meshed and connected via a second chain;

[0147] The conveyor roller drive device drives all the pipe conveyor rollers 21 to rotate via the first chain and the second chain.

[0148] Optionally, the pipe support frame 22 includes: two pipe support plates 221, two or more pipe support columns 222, and at least one pipe base 223;

[0149] Two pipe fitting support plates 221 are arranged in parallel, with one end of the pipe fitting support plate 221 facing the feeding position and the other end of the pipe fitting support plate 221 facing the automated cutting equipment.

[0150] Both ends of the pipe conveying roller 21 are fixed to the upper side of the two pipe support plates 221 by a bearing assembly 24. The bearing assembly 24 includes a rolling bearing 241 and a clamp 242. The rolling bearing 241 is fixed on the clamp 242, and the clamp 242 is fixed to the upper side of the pipe support plate 221.

[0151] The top of a pipe support column 222 is connected to the lower side of a pipe support plate 221;

[0152] The top of a pipe fitting base 223 is connected to the bottom of two pipe fitting support columns 222 respectively.

[0153] In this example, by setting up the pipe fitting support plate 221 and the pipe fitting 1 support base, the pipe fitting conveying roller 21 is positioned at a specified height, and sufficient support force is provided for the pipe fitting 1 and the pipe fitting conveying roller 21. By setting up the pipe fitting base 223, it is ensured that the pipe fitting conveying roller 21 and the pipe fitting 1 can be stably erected on the ground.

[0154] Furthermore, the pipe fitting base 223 includes: an upper base connecting plate 2231, a lower base connecting plate 2232, at least one base bolt 2233, an adjusting nut 2234, and at least one anchor bolt 2235;

[0155] The connecting plate 2231 on the base is connected to the bottom end of the two pipe support columns 222;

[0156] The lower connecting plate 2232 of the base is located below the upper connecting plate 2231 of the base;

[0157] One end of the base bolt 2233 is threaded to the upper connecting plate 2231 of the base, and the other end of the base bolt 2233 is threaded to the lower connecting plate 2232 of the base. The adjusting nut 2234 is screwed onto the base bolt 2233.

[0158] Anchor bolts 2235 pass through the lower connecting plate 2232 of the base and are inserted into the ground.

[0159] In this example, by setting base bolts 2233 and adjusting nuts 2234, the distance between the upper connecting plate 2231 and the lower connecting plate 2232 of the base is adjusted, thereby adjusting the height of the pipe conveying roller 21 and the pipe 1 on it, so as to enable the conveying of pipes 1 of different diameters and models, thus expanding the application range. By setting anchor bolts 2235, the pipe base 223 is firmly fixed to the ground, ensuring the stability of the pipe 1 during transportation.

[0160] In a preferred embodiment, the clamping device 3 includes: a detection mechanism 31, a clamping mechanism 32, a vertical moving mechanism 33, and a horizontal moving mechanism 34;

[0161] The detection mechanism 31 is connected to the pipe pressing mechanism 32 and the vertical moving mechanism 33 respectively. The detection mechanism 31 is used to detect the horizontal distance that the pipe fitting 1 moves on the pipe fitting conveying line 2. The detection mechanism 31 is also used to detect the vertical distance between the pipe pressing mechanism 32 and the top of the pipe fitting 1.

[0162] The pipe pressing mechanism 32 is used to press the pipe fitting 1 onto the pipe fitting conveyor line 2;

[0163] The vertical moving mechanism 33 is connected to the pressing mechanism 32, and the vertical moving mechanism 33 is used to control the pressing mechanism 32 to move in the vertical direction;

[0164] The horizontal moving mechanism 34 is connected to the vertical moving mechanism 33 and is also movably connected to the equipment conveyor line 4. The horizontal moving mechanism 34 is used to control the vertical moving mechanism 33 and the pressing mechanism 32 to move in the horizontal direction.

[0165] In this example, the vertical distance is detected by the detection mechanism 31 to ensure that the vertical moving mechanism 33 can ensure that the pressing mechanism 32 is at a suitable height regardless of the diameter and size of the pipe fitting 1 being transported by the pipe fitting conveyor line 2. This ensures that the vertical moving mechanism 33 can accurately and firmly press the pipe fitting 1 onto the pipe fitting conveyor line 2. The detection mechanism 31 controls the movement and stopping of the vertical moving mechanism 33 based on the vertical distance, and the vertical distance at which the detection mechanism 31 controls the movement and stopping of the vertical moving mechanism 33 can be set as needed.

[0166] The detection mechanism 31 detects the horizontal distance and monitors the delivery length of the pipe fitting 1. When the detection mechanism 31 detects that the horizontal distance has reached the preset delivery length, the detection mechanism 31 will instruct the pressing mechanism 32 to press the pipe fitting 1 onto the pipe fitting conveying line 2, so as to ensure that the pipe fitting conveying line 2 can output the specified delivery length of the pipe fitting 1 to the automated cutting equipment every time, thus ensuring the reliability and stability of the delivery operation to the automated cutting equipment.

[0167] In a preferred embodiment, the detection mechanism 31 includes: a proximity switch 311 and a sensor 312;

[0168] Proximity switch 311 is used to detect the vertical distance between the crimping mechanism 32 and the top of the fitting 1;

[0169] The proximity switch 311 is connected to the vertical moving mechanism 33. The proximity switch 311 is also used to send a vertical stop signal to the vertical moving mechanism 33. The vertical stop signal is used to instruct the vertical moving mechanism 33 to stop moving.

[0170] Sensor 312 is used to detect the horizontal distance that pipe fitting 1 moves on pipe fitting conveyor line 2;

[0171] Sensor 312 is connected to the pipe pressing mechanism 32. Sensor 312 is also used to send a pipe pressing signal to the pipe pressing mechanism 32. The pipe pressing signal is used to instruct the pipe pressing mechanism 32 to press the pipe 1 onto the pipe conveying line 2.

[0172] In this example, a detection distance is set in the proximity switch 311. When the proximity switch 311 moves to the detection distance from the top of the pipe fitting 1, the proximity switch 311 will generate a vertical stop signal. This detection distance can ensure that the pipe pressing mechanism 32 presses the pipe fitting 1 onto the pipe fitting conveyor line 2, and also ensures that when the pipe pressing mechanism 32 is detached from the pipe fitting 1, the pipe pressing mechanism 32 will not obstruct or rub against the conveying of the pipe fitting 1.

[0173] The feed distance is set in sensor 312. When sensor 312 detects that the horizontal distance that the pipe 1 moves on the pipe conveyor line 2 reaches the feed distance, sensor 312 will send a pipe pressing signal to the pipe pressing mechanism 32. The pipe pressing signal is used to instruct the pipe pressing mechanism 32 to press the pipe 1 tightly on the pipe conveyor line 2. At this time, the automated cutting equipment will receive the pipe 1 with a length equal to the feed distance and cut it, ensuring that the length of the pipe 1 cut by the automated cutting equipment each time is consistent with the feed distance.

[0174] In this embodiment, the proximity switch 311 is a position switch that can be operated without direct mechanical contact with a moving part. When an object approaches the sensing surface of the switch 311 to the operating distance, the switch can be activated without mechanical contact or the application of any pressure, thereby driving a DC electrical appliance or providing control commands to a computer (PLC) device. Exemplarily, the proximity switch 311 in this example is any one of a high-frequency oscillation proximity switch 311, a capacitive proximity switch 311, a Hall effect proximity switch 311, a photoelectric proximity switch 311, and an ultrasonic proximity switch 311.

[0175] High-frequency oscillating proximity switch 311: This switch utilizes the eddy currents generated inside a conductive object when it approaches the switch 311, thereby triggering the switch action. This type of switch has good anti-interference performance, a high switching frequency, and can detect various metallic objects.

[0176] Capacitive proximity switch 311: When an object moves toward the proximity switch 311, regardless of whether it is a conductor or not, it causes a change in the dielectric constant of the capacitor, thereby triggering the switch to operate. This type of switch can detect objects beyond conductors, including insulating liquids and powders.

[0177] Hall effect proximity switch 311: A switch made using a Hall element. When a magnetic object approaches the Hall switch, the Hall element generates the Hall effect, causing a change in the internal circuit state of the switch, thereby triggering the switch to operate. This type of switch must detect a magnetic object.

[0178] Photoelectric proximity switch 311: A light-emitting device and a photoelectric device are mounted in the same detection head in a certain direction. When a reflective surface (the object being detected) approaches, the photoelectric device receives the reflected light and triggers the switch. This type of switch can detect objects with reflective surfaces.

[0179] Ultrasonic proximity switch 311: A proximity switch 311 made using the Doppler effect principle. When an object moves close, the reflected signal received by the proximity switch 311 will generate a Doppler frequency shift, thereby triggering the switch to operate.

[0180] Sensor 312 is a device or apparatus that can sense (or respond to) a specified measurand and convert it into a usable signal output according to a certain rule. Sensor 312 is any one of inductive sensor 312, capacitive sensor 312, electrical contact sensor 312, grating sensor 312, laser sensor 312, and solid-state array sensor 312.

[0181] Inductive sensor 312: Utilizing the principle of electromagnetic induction, when the object being measured moves, it causes a change in the inductance of a coil, thereby measuring length or displacement. It has very high resolution, reaching 0.01 micrometers, and a measurement range typically less than 2 millimeters, but can be as large as tens of millimeters.

[0182] Capacitive sensor 312: Utilizing the principle of capacitance, when the object being measured moves, it causes a change in capacitance, thereby measuring length or displacement. It has a relatively large measurement range; for example, the large-range capacitive sensor 312 used in electronic calipers, which appeared in the early 1980s, has a measurement range of 150 mm.

[0183] Electrical contact sensor 312: Utilizes electrical contacts to emit electrical signals to determine whether the measured dimension is within acceptable limits. Movement of the electrical contacts can be transmitted directly by the measuring rod or amplified via levers or other mechanisms to improve sensitivity. Primarily used in automated measurement.

[0184] Grating sensor 312: Length measurement is performed using the moiré fringe phenomenon of a grating.

[0185] Laser sensor 312: It uses a laser beam to measure length and features high precision and long measurement distance.

[0186] Solid-state array sensor 312: such as a charge-coupled device (CCD), it uses the photoelectric conversion principle for length measurement. It is suitable for automatic measurement of multiple dimensions of small, complex-shaped workpieces.

The gear 3413 is connected to the equipment conveyor line 4. The horizontal power mechanism 341 is used to drive the pressing device 3 to move on the equipment conveyor line 4.

[0225] In this example, by setting a horizontal power mechanism 341, the pressing device 3 is moved on the equipment conveyor line 4, so as to press any pipe fitting 1 at any position on the pipe fitting conveyor line 2 onto the pipe fitting conveyor line 2, so as to meet the different feeding length requirements of the automated cutting equipment and expand the scope of application of this application.

[0226] Specifically, the horizontal power mechanism 341 includes: a horizontal motor 3411 and a horizontal reducer 3412;

[0227] The horizontal motor 3411 is connected to the input end of the horizontal reducer 3412;

[0238] The lubricating felt wheel 345 is used to lubricate the gear 3413 and / or the conveying rack 41 of the equipment conveyor line 4, which reduces the resistance encountered by the horizontal moving mechanism 34 during movement and ensures the stability of the horizontal moving mechanism 34 during movement.

[0239] In this embodiment, the lubricating felt wheel 345 is a special mechanical part mainly used to reduce friction and wear in mechanical equipment, thereby improving the equipment's operating efficiency and lifespan. The lubricating felt wheel 345 is typically made of felt material, a fibrous material formed through natural layering, possessing properties such as wear resistance, shock absorption, and noise reduction. This material allows the lubricating felt wheel 345 to effectively reduce friction and wear in mechanical equipment while providing the necessary lubrication.

[0240] The lubricating felt wheel 345 reduces direct metal-to-metal contact by forming a thin lubricating film on the friction surface, thereby reducing wear and heat generated by friction.

[0245] By setting up the wheel fixing plate 346 and the wheel axle 347, it is possible to disassemble and assemble the lubricating felt wheel 345, which facilitates its quick replacement and ensures the lubrication between the gear 3413 and the conveying rack 41.

[0267] S601: Input the position parameters, feed length, and stop time into the clamping device 3.

[0268] Specifically, position parameters, feed length and stop time are input into the controller of the clamping device 3. The controller is an electronic device used to control the detection mechanism 31, the pressing mechanism 32, the vertical moving mechanism 33 and the horizontal moving mechanism 34 of the clamping device 3.

[0269] S602: The clamping device 3 moves on the equipment conveyor line 4 according to the position parameters and stops at the designated position on the equipment conveyor line 4 corresponding to the position parameters.

When the horizontal motor 3411 has rotated the target number of revolutions, the clamping device 3 will reach the designated position corresponding to the position parameters.

[0272] S603: Pipeline 2 continuously conveys pipe 1 to the automated cutting equipment.

[0273] Specifically, start the pipe fitting conveyor line 2 to move the pipe fitting 1 to the bottom of the clamping device 3, and then stop the pipe fitting conveyor line 2;

[0277] Start the pipe fitting conveyor line 2 to continuously convey pipe fitting 1 to the automated cutting equipment.

[0278] S604: When the clamping device 3 detects that the horizontal distance that the pipe fitting 1 has been moved by the pipe fitting conveyor line 2 has reached the length of the conveying line, the clamping device 3 clamps the pipe fitting 1 onto the pipe fitting conveyor line 2, so that the pipe fitting 1 stops on the pipe fitting conveyor line 2.

[0279] Specifically, the sensor 312 of the detection mechanism 31 of the clamping device 3 detects the horizontal distance that the pipe fitting 1 moves on the pipe fitting conveyor line 2;

[0280] When the clamping device 3 determines that the horizontal distance has reached the conveying length, the clamping device 3 sends a clamping signal to the clamping mechanism 32. The clamping signal is used to instruct the clamping mechanism 32 to clamp the pipe 1 onto the pipe conveying line 2.

[0281] S605: When the time for the clamping device 3 to clamp the pipe fitting 1 on the pipe fitting conveyor line 2 reaches the stop time, the clamping device 3 disengages from the pipe fitting 1, allowing the equipment conveyor line 4 to continue outputting the pipe fitting 1 to the automated cutting equipment.

[0282] Specifically, the clamping device 3 starts timing when it generates a clamping signal to obtain the timing time;

[0283] When the timing device 3 determines that the timing has reached the stop time, the clamping device 3 generates a release signal, which is used to indicate that the clamping mechanism 32 is released from the pipe fitting 1.
