Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, and in particular to a cutting device for processing hardware products. Background Technology

[0002] Hardware products refer to standard parts, tools, building accessories, and daily metal products made primarily of metal materials through processes such as stamping, casting, and cutting. Their shapes are roughly divided into plate-shaped, rod-shaped, and tubular shapes. Among them, tubular hardware products are widely used in construction, machinery, and automotive fields, serving both structural support and fluid transmission functions. When tubular fittings are used as precision assembly or hydraulic system interfaces, high-precision cuts are required, which necessitates the use of laser cutting heads to cut the tubular fittings.

[0003] Currently, when laser cutting pipes, the pipe must first be extended to a certain length, and then the pipe is rotated to directly cut it using the laser cutting head. However, this operation has the following problems:

[0004] 1. When laser cutting pipes, the other end of the pipe is not supported, leaving the part of the pipe to be cut in a suspended state. If the pipe is cut in this state, it will cause the pipe to vibrate and deform, the cut to be skewed or the burrs to increase, which will seriously affect the dimensional accuracy and cross-sectional quality. At the same time, before laser cutting, it is usually necessary to feed the pipes one by one before cutting, but single-piece feeding and cutting is inefficient.

[0005] 2. When laser cutting pipes, relying solely on the cooling gas on one side of the laser cutting head for cooling is insufficient to effectively suppress heat accumulation and pipe wall deformation. This is especially true for thin-walled or long pipes, which can lead to problems such as an expanded heat-affected zone and reduced cut quality, thus reducing cutting accuracy and efficiency. Summary of the Invention

[0006] In view of the problems in the above-mentioned or existing technologies of laser cutting of pipes, such as the pipe part to be cut being suspended, low single-piece cutting efficiency, and low single-sided cooling efficiency, this invention is proposed.

[0007] To solve the above-mentioned technical problems, the present invention provides a cutting device for processing hardware products, which is achieved by the following specific technical means:

[0008] A cutting device for processing hardware products includes a machine body and a laser cutting head mounted thereon. The machine body is provided with a support mechanism for continuous processing through multiple stations via a turntable. The support mechanism includes a loading turntable mounted on the machine body and distributed on the left and right sides of the laser cutting head. Several support cylinders are installed in a circular array on the loading turntable. The loading turntables distributed on the left and right sides provide simultaneous support for the pipe being cut from both sides.

[0009] The slag removal mechanism includes a support turntable that cooperates with the carrying turntable. The support turntable is equipped with docking rings that correspond one-to-one with the support cylinders. Several grinding blocks are arranged in a circumferential array on the docking rings. The support turntable is equipped with a driving part for driving the grinding blocks to move synchronously closer to or away from the corresponding pipe fittings, and a rotating part for driving the docking rings to rotate. When cutting the pipe fittings, the grinding blocks can position and clamp the part of the pipe fitting to be cut. After the cutting is completed, the grinding blocks will extend into the cut and grind the left and right cut surfaces of the pipe fittings through the rotating part.

[0010] Cooling mechanism; The cooling mechanism includes a cooling component installed on the machine body. The right end face of the cooling component is provided with cooling pipe ports corresponding to the support cylinders. The turntable is provided with a side cooling section. Cooling gas is introduced into the tube of the part to be cut through the cooling pipe port, while the side cooling section sprays cooling gas from both sides of the cutting position, working synchronously with the cooling nozzles on the laser cutting head. The gas from the cooling pipe port can also blow out the residue after grinding by the slag removal mechanism.

[0011] Furthermore, the machine body is fixedly installed with annular brackets distributed on the left and right sides of the laser cutting head. The loading turntable is rotatably installed in the annular bracket. A first motor is fixedly installed on the annular bracket. The first motor is connected to the loading turntable on the right side through a set of first transmission gears. A central connecting shaft is fixedly installed through the center of the loading turntables on both sides. The left end of the central connecting shaft is fixedly connected to the center of the support turntable.

[0012] Furthermore, several positioning rods are hinged in a circular array within the support cylinder via torsion springs. Each positioning rod consists of a central horizontal bar and diagonal bars on the left and right sides. The hinge point of the torsion spring is far from the midpoint of the horizontal bar of the positioning rod. When the pipe is inserted into the support cylinder, the positioning rod adaptively fits and positions the pipe. A ball bearing is rotatably installed at the end of the diagonal bar of the positioning rod that is far from the corresponding horizontal bar.

[0013] Furthermore, a support ring frame is fixedly installed on the machine body on the left side of the left-side cargo turntable. The support turntable is rotatably installed inside the support ring frame. Through holes corresponding to the support cylinders are opened on the support turntable. A mating ring located at the through hole is rotatably installed inside the support turntable through a bearing.

[0014] Furthermore, the left end face of the docking ring is provided with a plurality of first slides in a circumferential array. A first slider is slidably installed in the first slide by a spring. A grinding block is fixedly installed at the end of the first sliders on the same docking ring that are close to each other by a spring telescopic rod.

[0015] Furthermore, the lower end of the grinding block has a triangular cross-section, and slots are provided on the left and right end faces of the grinding block, into which grinding plates are inserted.

[0016] Furthermore, the drive unit includes an electric telescopic rod fixedly installed on the left end face of the support turntable. The telescopic end of the electric telescopic rod is fixedly installed with a connecting disc located inside the support turntable. The connecting disc is fixedly installed with a fixed ring corresponding to the docking ring through a connecting rod. A connecting ring is rotatably installed on the side of the fixed ring close to the corresponding docking ring. The first slider on the same docking ring is hinged to the corresponding connecting ring through a hinge rod. A telescopic sleeve is fixedly installed between the docking ring and the connecting ring.

[0017] Furthermore, the rotating part includes a second motor fixedly installed on the left end face of the support turntable, a gear disk rotatably installed inside the support turntable, a second gear that meshes with the gear disk is fixedly sleeved at the output end of the second motor, and a first gear that meshes with the gear disk is fixedly sleeved on the outer ring wall of the mating ring.

[0018] Furthermore, the cooling assembly includes an electric slide rail fixedly mounted on the machine body and located on the left side of the support turntable. A support is fixedly mounted on the moving end of the electric slide rail, and a mating turntable is rotatably mounted on the right end face of the support. The cooling pipe port is fixedly mounted through the right end face of the mating turntable, and an extrusion block corresponding to the cooling pipe port is fixedly mounted on the right end face of the support turntable.

[0019] Furthermore, the side cooling section includes a support block fixedly installed on the upper end of the annular bracket, and symmetrical air outlets are fixedly installed on the side wall of the support blocks on the left and right sides that are close to each other.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. This cutting device for processing hardware products, through the coordinated use of a support mechanism, a slag removal mechanism, and a cooling mechanism, adopts a rotary table for continuous multi-station cutting, which significantly improves cutting accuracy and efficiency. The auxiliary support mechanism positions and clamps the product during cutting, and extends into the cut to simultaneously grind the cut surface after cutting, realizing integrated cutting and deburring processing to ensure cut quality. At the same time, the internal and external synergistic cooling forms all-round thermal management, optimizing the entire process of cutting, cooling, and slag removal to ensure the perpendicularity of the pipe fitting cut, burr-free cut, and minimize the heat-affected zone, greatly improving processing stability, accuracy, and cleanliness, and making it more suitable for the efficient and continuous production of high-precision pipe fittings.

[0022] 2. The cutting device for processing hardware products adopts rotary multi-station continuous cutting technology, combined with double-sided synchronous support and adaptive fitting positioning of pipe fittings, which can significantly improve laser cutting efficiency, reduce manual intervention, and ensure processing stability. The double-sided support effectively suppresses pipe fitting sinking and thermal deformation, while the adaptive positioning can adapt to different pipe diameters, thereby improving cutting accuracy and cutting efficiency.

[0023] 3. This cutting device for processing hardware products can assist the support mechanism in positioning and clamping the pipe parts during the cutting process. After the cutting is completed, it extends into the cut to grind the left and right cut surfaces of the pipe parts, realizing integrated processing from cutting to deburring, significantly improving processing efficiency, reducing secondary clamping errors, and ensuring the flatness and dimensional consistency of the cut.

[0024] 4. The cutting device for processing hardware products adopts an internal and external synergistic cooling design. Cooling gas is introduced into the pipe through the cooling pipe opening, and cooling airflow is synchronously sprayed from both sides of the cutting position in the side cooling section. This, together with the cooling nozzle of the laser cutting head, forms all-round thermal management, effectively reducing thermal deformation and improving cutting quality. At the same time, the cooling airflow can also efficiently blow away the residue after being processed by the slag removal mechanism, realizing the integration of cutting-cooling-slag removal, significantly improving processing accuracy and cleanliness. It is especially suitable for continuous and efficient processing of high-precision pipes. Attached Figure Description

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figure 1 A cutting device for processing hardware products includes a machine body 1 and a laser cutting head 2 mounted thereon. The machine body 1 is provided with a support mechanism 3 for continuous processing through a multi-station turntable. The support mechanism 3 includes a loading turntable 31 mounted on the machine body 1 and distributed on the left and right sides of the laser cutting head 2. Several support cylinders 32 are installed through the loading turntable 31 in a circumferential array. The loading turntables 31 distributed on the left and right sides provide simultaneous support for the pipe being cut from both sides.

[0039] Please see Figure 1 , Figure 2 and Figure 6 The slag removal mechanism 4 includes a support turntable 41 that cooperates with the load turntable 31. The support turntable 41 is provided with docking rings 42 that correspond one-to-one with the support cylinders 32. Several grinding blocks 43 are arranged in a circular array on the docking rings 42.

[0040] The support turntable 41 is provided with a drive part 44 for driving several grinding blocks 43 to move synchronously closer to or away from the corresponding pipe fittings, and a rotating part 45 for driving the docking ring 42 to rotate. When cutting the pipe fittings, the grinding blocks 43 can position and clamp the part of the pipe fitting to be cut. After the cutting is completed, the grinding blocks 43 will extend into the cut and grind the left and right cut surfaces of the pipe fittings through the rotating part 45.

[0041] Please see Figure 1 , Figure 2 , Figure 6 and Figure 9 Cooling mechanism 5; Cooling mechanism 5 includes a cooling component 51 installed on the machine body 1. The right end face of the cooling component 51 is provided with a cooling pipe port 52 corresponding to the support cylinder 32. The turntable 31 is provided with a side cooling section 53. Cooling gas is introduced into the tube of the part to be cut through the cooling pipe port 52, while the side cooling section 53 sprays cooling gas from both sides of the cutting position, working synchronously with the cooling nozzle on the laser cutting head 2. The gas from the cooling pipe port 52 can also blow out the residue after grinding by the slag removal mechanism 4.

[0042] In practice, when laser cutting of pipes is required, the pipes to be cut are fed one by one through the left and right distributed support cylinders 32 and through the docking ring 42 by an external feeding device (not shown in the figure) until the left end of the pipe is moved to the position of the cooling component 51. Then, subsequent pipes can be loaded until all pipes are installed. At this time, the part of the pipe to be cut can be moved directly below the laser cutting head 2 by an external feeding device (not shown in the figure) for subsequent cutting operations.

[0043] Please see Figure 1 , Figure 3 and Figure 4 The machine body 1 is fixedly installed with annular brackets distributed on the left and right sides of the laser cutting head 2. The loading turntable 31 is rotatably installed in the annular bracket. The first motor 311 is fixedly installed on the annular bracket. The first motor 311 and the loading turntable 31 on the right side are connected by a first transmission gear set. The center connecting shaft 312 is fixedly installed through the center of the loading turntables 31 on both the left and right sides. The left end of the center connecting shaft 312 is fixedly connected to the center of the support turntable 41.

[0044] Please see Figure 1 , Figure 3 , Figure 4 and Figure 5 Inside the support cylinder 32, several positioning rods 33 are hinged in a circular array by torsion springs. Each positioning rod 33 consists of a central horizontal bar and diagonal bars on the left and right sides. The hinge point of the torsion spring is far from the midpoint of the horizontal bar of the positioning rod 33. When the pipe is inserted into the support cylinder 32, the positioning rod 33 adaptively fits and positions the pipe. A ball bearing 331 is rotatably installed at the end of the diagonal bar of the positioning rod 33 that is far from the corresponding horizontal bar.

[0045] In actual operation, the positioning rods 33 distributed in a circumferential array can be arranged in six or eight symmetrical arrangements, so that when the pipe is inserted into the support cylinder 32, the outer wall of the pipe is simultaneously contacted by multiple sets of symmetrically distributed positioning rods 33. When the pipe is inserted into the support cylinder 32, the outer wall of the pipe contacts the inclined part of the positioning rod 33, causing it to rotate at the hinge point. The torsion spring will cause the end of the positioning rod 33 to continuously press against the outer wall of the pipe to form a uniformly distributed radial clamping force to avoid the pipe shaking. Similarly, the support cylinder 32 on the other side provides adaptive support for the pipe on the other side.

[0046] When the laser cutting head 2 cuts the pipe, an external rotating device (not shown in the figure) is activated to rotate the pipe to achieve circumferential cutting. At this time, the support cylinders 32 distributed on the left and right provide synchronous support on both sides of the pipe, providing stable clamping for the cutting end of the pipe, thereby solving the problem of vibration and deformation caused by single-sided suspension during the pipe cutting process.

[0047] After the first pipe is cut, the first motor 311 is started to rotate the right-side turntable 31 through the first transmission gear set. The right-side turntable 31 will drive the left-side turntable 31 and the support turntable 41 to rotate synchronously through the central connecting shaft 312, so that the grinding block 43 of the slag removal mechanism 4 and the support cylinder 32 are in corresponding positions. The next pipe to be cut is moved to the area below the laser cutting head 2, thereby realizing multi-station continuous cutting of the turntable, which can significantly improve the efficiency of laser cutting and ensure the continuity and stability of the processing flow.

[0048] Furthermore, when rotating to switch positions, the grinding block 43 and the left support cylinder 32 will clamp the cut and separated pipe parts, so that the cut and separated pipe parts will not fall off during the rotation process.

[0049] Then, all pipe fittings can be cut using the above-described steps.

[0050] Please see Figure 1 , Figure 2 , Figure 3 and Figure 6 A support ring frame is fixedly installed on the body 1 on the left side of the left-side load turntable 31. The support turntable 41 is rotatably installed inside the support ring frame. The support turntable 41 has through holes that correspond one-to-one with the support cylinder 32. The docking ring 42 located at the through hole is rotatably installed inside the support turntable 41 through a bearing.

[0051] Please see Figure 7 and Figure 8The left end face of the docking ring 42 is provided with a plurality of first slides 421 in a circular array. A first slider 422 is slidably installed in the first slide 421 by means of a spring. A grinding block 43 is fixedly installed at one end of the first slider 422 on the same docking ring 42 by means of a spring telescopic rod.

[0052] Please see Figure 7 and Figure 8 The lower cross-section of the grinding block 43 is triangular, and slots are provided on the left and right end faces of the grinding block 43, into which a grinding plate 431 is inserted.

[0053] Please see Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8 The drive unit 44 includes an electric telescopic rod 442 fixedly installed on the left end face of the support turntable 41. The telescopic end of the electric telescopic rod 442 is fixedly installed with a connecting disc 441 located inside the support turntable 41. The connecting disc 441 is fixedly installed with a fixed ring 443 corresponding to the docking ring 42 through a connecting rod. A connecting ring 444 is rotatably installed on the side of the fixed ring 443 close to the corresponding docking ring 42. The first slider 422 on the same docking ring 42 is hinged to the corresponding connecting ring 444 through a hinge rod. A telescopic sleeve 46 is fixedly installed between the docking ring 42 and the connecting ring 444.

[0054] Please see Figure 2 , Figure 3 , Figure 6 and Figure 7 The rotating part 45 includes a second motor 451 fixedly installed on the left end face of the support turntable 41. A gear 452 is rotatably installed inside the support turntable 41. A second gear that meshes with the gear 452 is fixedly sleeved at the output end of the second motor 451. A first gear that meshes with the gear 452 is fixedly sleeved on the outer ring wall of the mating ring 42.

[0055] Please see Figure 1 , Figure 2 and Figure 10 The cooling assembly 51 includes an electric slide rail fixedly installed on the machine body 1 and located on the left side of the support turntable 41. A support 511 is fixedly installed on the moving end of the electric slide rail. A mating turntable 512 is rotatably installed on the right end face of the support 511. A cooling pipe port 52 is fixedly installed through the right end face of the mating turntable 512. An extrusion block 521 corresponding to the cooling pipe port 52 is fixedly installed on the right end face of the support plate.

[0056] In actual operation, before the laser cutting head 2 cuts the pipe, the electric telescopic rod 442 is activated so that its telescopic end pulls the fixing ring 443 to the left through the connecting disc 441. The fixing ring 443 will then pull the connecting ring 444 to the left in sync. The movement of the connecting ring 444 will move the first slider 422 toward the corresponding pipe through the hinge rod. The spring provides guidance for the first slider 422 to slide within the first slide rail 421.

[0057] When the first slider 422 slides to the middle of the first slide rail 421, the electric telescopic rod 442 is turned off. At this time, the first slider 422 close to the periphery of the pipe will drive the grinding block 43 to form a ring clamp on the outer ring wall of the pipe. At this time, the spring telescopic rod is in a slightly compressed state, so that the grinding block 43 around the periphery will assist the support mechanism 3 in positioning and clamping the pipe in the cutting part during the cutting process.

[0058] The electric slide rail is activated to bring the support 511 close to the leftmost end of the pipe. The turntable 512 will insert the cooling pipe 52 into the pipe. The extrusion block 521 is made of rubber. When the turntable 512 extrudes the leftmost end of the pipe, the extrusion block 521 will seal the leftmost end of the pipe through deformation to prevent the loss of cooling gas, while providing the pipe with a rightward extrusion force.

[0059] After all the pipe fittings have been cut, the electric telescopic rod 442 is activated again so that its telescopic end continues to pull the connecting disc 441 to the left, thereby bringing the first slider 422 around the perimeter closer to the outer ring wall of the pipe fitting. At this time, the spring telescopic rod is in a high-pressure state. At this time, the pipe fitting is pushed to the left by the external feeding device (not shown in the figure), and the electric slide rail is activated at the same time so that it moves synchronously to the left with the mating turntable 512. The uncut part of the pipe fitting will push the cut part to the left.

[0060] When the pipe cut reaches the lower end of the grinding block 43, the grinding block 43 can use the sharp corner of the triangle to make priority contact with the pipe cut to achieve precise positioning. After positioning, the grinding block 43 will be squeezed into the cut by the spring telescopic rod. When the grinding block 43 is inserted into the pipe cut, the external feeding device (not shown in the figure) and the electric slide rail will stop running. At this time, the grinding block 43 will bring the grinding plate 431 into contact with the pipe cut.

[0061] Next, the second motor 451 is started so that it rotates all the mating rings 42 synchronously through the gear plate 452, the second gear and the first gear, thereby driving the grinding plate 431 around the pipe to rotate, so as to grind the left end of the uncut part and the right end of the cut part of the pipe, so as to realize the integrated processing from cutting to deburring, significantly improving the processing efficiency.

[0062] The telescopic sleeve 46 connects the docking ring 42 and the connecting ring 444 into a whole, so that during the rotation of the docking ring 42 and the connecting ring 444, the telescopic sleeve 46 mainly bears the force and reduces the force on the hinge rod. The grinding plate 431 installed in the slot can be replaced according to the degree of wear. The old grinding plate 431 can be directly pulled out from the slot and the new grinding plate 431 can be inserted without disassembling the whole grinding block 43, thus improving maintenance efficiency.

[0063] After grinding is completed, the electric telescopic rod 442 is activated in reverse to push the connecting disc 441 to the right, thereby causing the first slider 422 to move synchronously away from the pipe. After the grinding block 43 moves away from the pipe, the electric telescopic rod 442 stops running, and the external feeding device (not shown in the figure) and the electric slide rail are activated again to transport the cut pipe to the left until the cut pipe detaches from the support turntable 41 and falls, thus completing the cutting of a pipe.

[0064] Please see Figure 1 , Figure 2 , Figure 3 , Figure 9 and Figure 10 The side cooling section 53 includes a support block 531 fixedly installed on the upper end of the annular bracket, and symmetrical air outlets 532 are fixedly installed on the side wall of the support blocks 531 on both sides.

[0065] In actual operation, the air outlets 532 on the left and right sides of the upper end of the ring support are arranged symmetrically. During the cutting process, the left and right air outlets 532 spray cooling gas from the front and rear sides of the cutting position at the same time. This symmetrical airflow covers the cutting area, so that the heat at the cut of the pipe is evenly carried away, eliminating the thermal stress concentration phenomenon caused by unilateral cooling.

[0066] Furthermore, when the laser cutting head 2 cuts the pipe, the cooling port 52 introduces cooling gas into the pipe, and the airflow forms a cooling layer along the pipe wall. This, combined with the cooling nozzle of the laser cutting head 2, forms a coordinated cooling effect inside and outside, effectively reducing thermal deformation and improving cutting quality.

[0067] After the slag removal mechanism 4 completes the cutting process, the high-pressure gas output from the cooling pipe port 52 acts directly on the inner wall of the cut, discharging the metal debris attached to the edge of the cut along the airflow direction, realizing the integration of cutting-cooling-slag removal, and significantly improving processing accuracy and cleanliness.

[0068] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
