Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0021] To address the shortcomings of existing technologies, this invention automates the feeding, punching, punching, and unloading of pipe fittings by incorporating a cooperating feeding assembly, punching assembly, feeding assembly, support assembly, and length adjustment assembly. This improves the automation level of the punching equipment and reduces labor costs. Simultaneously, the punching tool can extend into the end of the pipe fitting for punching, meaning the punching tool punches from the inside out, preventing deformation of the pipe fitting end, ensuring a high yield rate, reducing the repair or rework rate, and thus guaranteeing the punching accuracy of the equipment. Furthermore, the length adjustment assembly can adjust the length of the feeding channel to accommodate different lengths, improving the adaptability of the punching equipment.

[0022] See appendix Figure 1-6 This embodiment provides a punching device for pipe fittings, comprising: Two sets of feeding assemblies 1 arranged opposite each other have a receiving area that can support one end of the pipe fitting 6. The receiving areas of at least two sets of feeding assemblies 1 are arranged opposite each other to form a feeding channel for the pipe fitting 6. At least one set of punching components 2, with a feeding component 1 disposed above the punching components 2, and the outlet of the feeding channel communicating with the punching area of ​​the punching components 2; the punching components 2 include a punching part 213 having at least one punching tool 2131; the punching tool 2131 is correspondingly disposed with the pipe 6, and each punching tool 2131 can extend into the end of the pipe 6 to punch the pipe 6; The feeding assembly 3 can abut against the pipe 6 set in the feeding channel, so as to drive the pipe 6 to move to the punching assembly 2 in a preset posture; Support component 4 is provided with at least one set of sliders 43; The length adjustment component 5 is connected to the two sets of feeding components 1 respectively. Driven by the length adjustment component 5, the two sets of feeding components 1 move along the length direction of the sliding member 43 to adjust the length of the feeding channel.

[0023] In this embodiment, by setting up a feeding assembly 1, a punching assembly 2, a feeding assembly 3, a support assembly 4, and a length adjustment assembly 5 that cooperate with each other, the automatic feeding, feeding, punching, and unloading of the pipe fitting 6 is realized, improving the automation level of the punching equipment and reducing labor costs. At the same time, the punching cutter 2131 can extend into the end of the pipe fitting 6 to punch, that is, the punching cutter punches from the inside out, which can avoid deformation of the end of the pipe fitting 6, ensure the pass rate of the produced pipe fitting 6, reduce the repair rate or rework rate of the pipe fitting 6, and thus ensure the punching accuracy of the punching equipment. At the same time, the punching structure is simplified, reducing the manufacturing cost of the punching equipment. Meanwhile, the length adjustment assembly 5 can adjust the length of the feeding channel, thereby adapting to different lengths and improving the adaptability of the punching equipment.

[0024] In this embodiment, the punching equipment mainly punches the end of the pipe fitting 6. With a set of punching components 2, the punching equipment can punch one end of the pipe fitting 6. That is, the punching equipment is suitable for punching one side of the pipe fitting 6. It can be seen that the adaptability of this embodiment is high. It can adapt to different types of pipe fittings and different punching needs without replacing the punching equipment, thus reducing replacement costs.

[0025] In some other possible embodiments, when two sets of punching assemblies 2 are provided, the punching equipment can punch both ends of the pipe 6, and punching both ends of the pipe 6 simultaneously can improve the punching efficiency.

[0026] In this embodiment, the pipe 6 can be a tubular structure of any shape, and the cross-section of the pipe 6 can be circular, elongated, square, rectangular, or D-shaped, etc.

[0027] In this embodiment, a power distribution box is also included. The power distribution box provides power to the components that require power in the punching equipment for pipe fittings. The power distribution box is fixedly mounted on the support assembly 4.

[0028] In this embodiment, at least one punching tool 2131 is provided on the punching component 213. The at least one punching tool 2131 is spaced apart along the height direction of the punching equipment. By spacing at least one punching tool 2131, it is possible to punch at least two pipes 6 at the same time, or to punch two spaced holes at one end of the pipe 6 at the same time, thereby improving the punching efficiency.

[0029] Preferably, two punching cutters 2131 are spaced apart on the punching component 213. The two corresponding pipes 6 are pushed by the feeding component 3 to enter the punching area of ​​the punching component 2 at the same time in a preset posture. The two punching cutters 2131 can punch the two pipes 6 at the same time, further improving the punching efficiency of the pipes 6.

[0030] Specifically, the spacing between two adjacent punching tools 2131 is determined according to the punching position of the pipe 6, and is not limited here.

[0031] In this embodiment, the shape of the punching tool 2131 and the height of the punch protrusion on the punching part 213 are determined according to the size of the required opening on the pipe 6.

[0032] Preferably, the cross-section of the punching tool 2131 is U-shaped, and the shape of the hole on the pipe 6 is also U-shaped.

[0033] In some possible embodiments, the punching assembly 2 includes a front punching die assembly 21 and a rear punching die assembly 22 disposed opposite to each other; The punching die assembly 22 has a pipe fitting receiving area, which is located below the outlet of the feed channel; The punching front die assembly 21 includes a punching component 213. The punching rear die assembly 22 drives the pipe 6 to move toward the punching front die assembly 21 to its limit position. The punching component 213 punches the pipe 6. The punching rear die assembly 22 can transport the pipe 6 to be punched to the punching position and punch the pipe 6 through the punching front die assembly 21. By setting up the punching front die assembly 21 and the punching rear die assembly 22 that cooperate with each other, the punching structure is simplified and the structural complexity of the punching assembly is reduced while ensuring the punching capacity.

[0034] In this embodiment, the moving direction of the punching front die assembly 21 and the moving direction of the punching rear die assembly 22 are arranged parallel; the axis of the pipe 6 disposed in the punching assembly 2 is arranged perpendicular to the moving direction of the punching front die assembly 21.

[0035] In this embodiment, the specific structure of the punching back die assembly 22 and the punching front die assembly 21 is not limited, as long as they can achieve punching of the pipe 6.

[0036] In some possible embodiments, the punching die assembly 22 includes a feeding cylinder 221 and a first base 222 provided with a tube receiving area; The drive end of the feeding cylinder 221 is fixedly connected to the first base 222. Under the drive of the feeding cylinder 221, the first base 222 moves toward the punching front die assembly 21. By simply setting the first base 222 and the feeding cylinder 221 to cooperate with each other, the pipe 6 can be stably driven toward the punching front die assembly 21. This simplifies the structure of the punching back die assembly 22 while ensuring stable force transmission, avoids the use of complex linkage structures, and thus reduces the manufacturing cost of punching equipment for pipes.

[0037] In this embodiment, the extension and retraction direction of the feeding cylinder 221 is perpendicular to the axis of the pipe 6, and the first base 222 is located above the first support plate 42.

[0038] In some possible embodiments, the punching front die assembly 21 includes a second base 211, a punching cylinder 212, and a punching part 213; The punching component 213 is disposed inside the second base 211. The first end of the punching component 213 is fixedly connected to the punching cylinder 212, and the second end of the punching component 213 is provided with at least one punching cutter 2131. The punching cylinder 212 drives the punching component 213 to move toward the pipe 6 to punch the pipe 6. By setting the second base 211, the punching cylinder 212 and the punching component 213 that cooperate with each other, the punching function of the pipe 6 can be realized. On the basis of ensuring stable force transmission, the structure of the punching front mold assembly 21 can be simplified, the use of complex linkage structure can be avoided, and the manufacturing cost of punching equipment for pipes can be reduced.

[0039] In this embodiment, the arrangement direction of the punch 213 is perpendicular to the axial direction of the pipe 6. The second base 211 is a shell with an inner cavity. Part of the punch 213 is disposed in the inner cavity. One end of the punch 213 with a punching tool 2131 protrudes from the second base 211. The punching tool 2131 is disposed on the side close to the pipe 6.

[0040] In some possible embodiments, the punching die assembly 21 further includes a guide 215, a limiting member 214, and an elastic member; The limiting member 214 and the tube 6 are respectively disposed on both sides of the second base 211. One end of the limiting member 214 is fixedly disposed on the first support plate 42, and the other end of the limiting member 214 is fixedly connected to one end of the elastic member, and the other end of the elastic member is fixedly connected to the second base 211. The first support plate 42 is provided with a slide rail 422, and the bottom of the second base 211 is provided with a slider that cooperates with the slide rail 422. The guide member 215 protrudes from the second base 211, and one end of the guide member 215 is provided with a guide slope. The guide slope can abut against the pipe 6 to drive the second base 211 to move toward the limiting member 214 to the limit position. Under the action of the elastic member, the second base 211 moves along the slide rail 422 toward the pipe 6. By setting the guide member 215, the limiting member 214 and the second base 211 that cooperate with each other, the punching tool 2131 can be automatically misaligned with the end of the pipe 6 under the drive of the second base 211, and automatically reset when the second base 211 is compressed to the limit position, so that the punching tool 2131 can extend into the end of the pipe 6, thereby realizing punching from the inside to the outside, which can further avoid deformation of the pipe and ensure punching accuracy.

[0041] In this embodiment, the extension and retraction direction of the elastic element is parallel to the arrangement direction of the slide rail 422, and the arrangement direction of the slide rail 422 is also parallel to the arrangement direction of the sliding element 43.

[0042] Specifically, the elastic element is a spring.

[0043] In this embodiment, the guide member 215 is fixedly mounted on the second base 211, and the guide slope is set towards the side of the tube 6. The distance between the guide slope and the tube 6 gradually increases from the punching front die assembly 21 to the punching rear die assembly 22.

[0044] In this embodiment, when the elastic member is in a compressed state, the second base 211 moves toward the limiting member 214. When the elastic member is in its original length state, the second base 211 is in its initial position. When the second base 211 is in its initial position, the punching tool 2131 can punch holes in the pipe 6.

[0045] In some possible embodiments, the support assembly 4 includes a support frame 41 and two first support plates 42; The first set of feeding components 1 is mounted on a first support plate 42, and the second set of feeding components 1 is mounted on another first support plate 42; The sliding member 43 is mounted on the support frame 41, and the two first support plates 42 are provided with sliding blocks that cooperate with the sliding member 43. The two first support plates 42 can move towards each other or away from each other along the sliding member 43. By setting the two sets of feeding components 1 on the two first support plates 42 respectively, and each first support part 42 is provided with a slider, the distance between the two sets of feeding components 1 can be quickly adjusted, thereby adapting to pipes 6 of different lengths and improving the adaptability of the punching equipment.

[0046] In this embodiment, the support frame 41 includes a support part and a mounting part. The bottom of the support part abuts against the ground, the mounting part is disposed on the top of the support part, and the sliding member 43 is disposed on the mounting part.

[0047] In this embodiment, at least one set of sliding members 43 are provided on the mounting part. The at least one set of sliding members 43 are arranged along the arrangement direction from the punching front die assembly 21 to the punching rear die assembly 22, and the sliding members 43 are arranged along the arrangement direction of the two sets of feeding assemblies 1.

[0048] Specifically, the slider 43 is a slide rail.

[0049] In this embodiment, both the feeding assembly 1 and the punching assembly 2 are fixedly mounted on the first support plate 42, meaning that the punching assemblies 2 on both sides can move synchronously, thereby adjusting the distance between the punching assemblies 2 on both sides, further ensuring that different pipe fittings 6 can be punched, and further improving the adaptability of the punching equipment.

[0050] In some possible embodiments, a material discharge groove 421 is provided on the first support plate 42, and the pipe 6 after punching can be moved to the bottom of the punching equipment through the material discharge groove 421 for unloading the pipe 6. The second base 211 is provided with a discharge hole 2111. The waste material after punching can be moved to the bottom of the punching equipment through the discharge hole 2111 and the discharge groove 421 in sequence. By setting the discharge groove 421 on the first support plate 42, the discharge structure can be simplified and the waste material and the punched pipe 6 can be discharged smoothly, thereby reducing the manufacturing cost.

[0051] In this embodiment, the punching die assembly 21 is fixedly mounted on the first support 42. Along the direction from the top to the bottom of the punching equipment, a discharge hole 2111 and a discharge groove 421 are sequentially arranged so that the waste material can fall to the bottom of the punching equipment through the discharge hole 2111 and the discharge groove 421. The size of the discharge groove 421 is much larger than the size of the discharge hole 2111. This arrangement can ensure that the punched pipe 6 can fall to the bottom of the punching equipment through the discharge groove 421.

[0052] In this embodiment, the size and location of the material discharge chute 421 are not specified, as long as the material discharge chute 421 can discharge waste materials and pipe fittings 6.

[0053] In some possible embodiments, the punching assembly 2 is arranged in a one-to-one correspondence with the first support plate 42. The punching assembly 2 is disposed on the first support plate 42, and the punching assembly 2 and the feeding assembly 1 disposed on the same first support plate 42 can move synchronously. The feeding assembly 3 includes a feeding rod 31, a feeding block 32 fixedly mounted on the feeding rod 31, and a first feeding mechanism 33 and a second feeding mechanism 34 arranged opposite to each other. The first end of the first feeding mechanism 33 and the first end of the second feeding mechanism 34 are respectively connected to the first end and the second end of the feeding rod 31. The first feeding mechanism 33 and the second feeding mechanism 34 move synchronously to drive the feeding rod 31 and the feeding block 32 set on it to rotate back and forth. By setting the feeding assembly 3, the tube 6 can be guided so that the tube 6 enters the punching assembly 2 in a preset posture, thereby realizing the rapid punching of non-circular tubes and improving the efficiency of punching non-circular tubes.

[0054] In this embodiment, the number of material feeding blocks 32 is not limited, as long as it can feed the pipe 6. Preferably, two material feeding blocks 32 are provided at intervals on the material feeding rod 31 to avoid the pipe 6 being unable to rotate due to localized force.

[0055] In this embodiment, the axial direction of the feeding rod 31 is parallel to the axial direction of the tube 6.

[0056] In this embodiment, when the pipe 6 is about to be changed from the feeding channel to the preset posture, the feeding rod 31 is located diagonally above the pipe 6, and when the feeding rod 31 drives the feeding block 32 to rotate at a preset angle, the feeding block 32 can abut against the pipe 6, so as to drive the pipe 6 to rotate to the preset posture in the feeding channel and enter the punching assembly 2 in the preset posture for punching. This setting can realize the rapid punching of non-circular pipes and ensure the efficiency of punching non-circular pipes.

[0057] In this embodiment, the feeding channel formed by the feeding assembly 1 gradually decreases in size until it is approximately equal to the width of the tube 6, so as to ensure that the tube 6 does not change its preset posture.

[0058] In some possible embodiments, the first feeding mechanism 33 and the second feeding mechanism 34 are identical. The first feeding mechanism 33 includes a second support plate 331, a third support plate 332, a feeding cylinder 333, and a connecting rod 334. The first end of the second support plate 331 is fixedly connected to the first support plate 42. The second support plate 331 extends toward the top of the punching equipment. The material feeding rod 31 passes through the second end of the second support plate 331 of the first material feeding mechanism 33 and the second end of the second support plate 331 of the second material feeding mechanism 34 in sequence, and is rotatably connected to the second end of the second support plate 331. The first end of the third support plate 332 is connected to the middle of the second support plate 331, and the second end of the third support plate 332 is fixedly connected to one end of the feeding cylinder 333. The driving end of the feeding cylinder 333 is rotatably connected to the first end of the connecting rod 334, and the second end of the connecting rod 334 is fixedly connected to one end of the feeding rod 31. By setting feeding mechanisms on both sides of the feeding rod 31, the driving force of the feeding rod 31 can be guaranteed, and the two ends of the feeding rod 31 can be rotated synchronously to ensure the feeding effect on the pipe fitting 6.

[0059] In this embodiment, the second support plate 331, the third support plate 332, the material feeding cylinder 333 and the connecting rod 334 are connected in sequence and form a U-shaped structure. The driving end of the material feeding cylinder 333 is arranged diagonally above the punching equipment. That is, the material feeding cylinder 333 drives the connecting rod 334 to swing back and forth, thereby driving the material feeding block 32 to rotate back and forth within a preset rotation range, thereby realizing the material feeding operation of the pipe 6.

[0060] In this embodiment, the feeding component 1 is vertically mounted on the support component 1, and the second support plate 331 of the feeding component 3 is mounted diagonally above the punching equipment. This arrangement can prevent the feeding component 3 from interfering with the feeding of the pipe 6 and ensure rapid feeding of the pipe 6.

[0061] In this embodiment, two sets of feeding components 1 are symmetrically arranged at both ends of the pipe 6, and two sets of punching components 2 are symmetrically arranged at both ends of the pipe 6.

Forward lead screw nut and reverse lead screw nut are respectively fixedly installed in the first group of feeding components 1 and the second group of feeding components 1. Driven by lead screw 51, the first group of feeding components 1 and the second group of feeding components 1 run in opposite directions. By setting forward lead screw nut and reverse lead screw nut respectively, the movement directions of the two groups of feeding components 1 can be reversed, thereby quickly adjusting the length between the two groups of feeding components 1, thus adapting to pipes 6 of different lengths and further improving the adaptability of the punching equipment.

[0063] In this embodiment, the lead screw 51 is located below the feeding assembly 1 and does not interfere with the pipe 6 in the feeding channel. The axial direction of the lead screw 51 is parallel to the axial direction of the feeding rod 31.

[0064] The working process of the punching equipment for pipe fittings is as follows: Pipe fitting 6 is placed in the feeding channel formed by at least two sets of feeding components 1. Driven by the first feeding mechanism 33 and the second feeding mechanism 34, the feeding rod 31 drives the feeding block 32 to rotate, and then the feeding block 32 performs feeding operation on the pipe fitting 6 so that the pipe fitting 6 enters the pipe fitting receiving area of ​​the punching back die assembly 22 in a preset posture. The feeding cylinder 221 of the punching back die assembly 22 drives the pipe fitting 6 to move towards the punching front die assembly 21. Under the drive of the punching cylinder 212 and the guide 215, the punching cutter 2131 of the punching part 213 of the punching front die assembly 21 extends into the interior of the pipe fitting 6. The punching cutter 2131 punches the pipe fitting 6 from the inside to the outside. After punching is completed, the feeding cylinder 221 returns to the initial position, and the pipe fitting 6 and the waste material fall from the drop chute 421 below the punching equipment. At this time, the entire punching process of the pipe fitting 6 is completed.
