Description

Technical Field

[0001] This utility model belongs to the technical field of pipe cutting machines, and specifically relates to a pipe cutting machine with an alignment structure. Background Technology

[0002] A pipe cutting machine is a specialized mechanical device used for cutting various types of pipes, widely used in metal processing, construction, and manufacturing industries. Its main function is to cut tubular materials (such as metal pipes and plastic pipes) to the required length or shape. Modern pipe cutting machines are typically equipped with CNC systems and automatic feeding devices, enabling efficient and precise cutting to meet the needs of large-scale production. While pipe cutting machines are valuable in many applications, they also have drawbacks. Traditional pipe cutting machines may produce dimensional errors during the cutting process, affecting subsequent processing. The conventional solution is to introduce a Computer Numerical Control (CNC) system to improve cutting accuracy and consistency, while also facilitating automated operation. Although this method significantly improves cutting accuracy, its disadvantages include the greater complexity of CNC systems compared to traditional equipment, requiring professional technicians for maintenance and operation. Equipment malfunctions may require considerable time for diagnosis and repair, greatly increasing maintenance complexity and requiring downtime for repairs, thus reducing work efficiency. Therefore, a new structure is proposed to address these issues. Utility Model Content

[0004] This utility model is achieved through the following technical solution: a pipe cutting machine with an alignment structure, comprising: a clamping box, an extrusion plate and a push-pull rod, a worktable is provided below the clamping box, a set of push-pull sliding grooves are respectively opened on the left and right sides of the top of the worktable, and a cutting opening is opened on the rear side of the clamping box.

[0005] The clamping box has a set of push-pull slides on the left and right sides of the bottom, and a connecting rod on the left and right sides of the front. A push-pull rod is provided between the two sets of connecting rods. A screw-connecting hole 1 is provided through the left side of the front of the clamping box, and a screw-connecting hole 2 is provided through the center of the right side of the clamping box.

[0006] The screw hole one is provided with a screw rod one inside, the screw rod one has a handle one on the front side, and the screw rod one has an extrusion plate one on the rear side. The screw hole two is provided with a screw rod two inside, the screw rod two has a handle two on the right side, and the screw rod two has an extrusion plate two on the left side.

[0007] In a preferred embodiment, a cutting mechanism is provided between the two sets of push-pull slides. The position of the cutting mechanism is opposite to the position of the cutting opening, the thickness of the cutting mechanism matches the width of the cutting opening, and the clamping box is provided with a clamping groove inside.

[0008] In a preferred embodiment, the clamping box and the push-pull slide are an integral structure, and the length, width and height of the push-pull slide match the length, width and height of the push-pull slide groove.

[0009] In a preferred embodiment, the distance between the two sets of push-pull slide bars is the same as the distance between the two sets of push-pull slide grooves. The push-pull slide bars have a convex structure, and the push-pull slide grooves are structurally matched with the push-pull slide bars. The push-pull slide bars slide inside the push-pull slide grooves, ensuring the stability of the clamping box movement.

[0010] In a preferred embodiment, the first extrusion plate is located inside the front side of the clamping box, and the second extrusion plate is located inside the right side of the clamping box. Both the first extrusion plate and the second extrusion plate are made of rubber.

[0011] In a preferred embodiment, the width of the extrusion plate is matched with the distance between the cutting opening and the inner wall of the left side of the clamping groove. The front side of the extrusion plate is connected to the rear side of the screw via a set of rotating plates, which are movably embedded inside the front side of the extrusion plate.

[0012] In a preferred embodiment, the width of the second extrusion plate matches the width of the clamping groove. The right side of the second extrusion plate is connected to the left side of the second screw via a set of second rotating plates. The second rotating plates are movably embedded inside the right side of the second extrusion plate. The first rotating plate rotates inside the first extrusion plate as the first screw rotates, thus ensuring that the first extrusion plate remains stationary when the first screw rotates and advances. The second rotating plate rotates inside the second extrusion plate as the second screw rotates, thus ensuring that the second extrusion plate remains stationary when the second screw rotates and advances, so that the first and second extrusion plates can only move in the horizontal direction.

[0013] In a preferred embodiment, the outer side of the screw is provided with a thread, and the inner side of the screw hole is provided with an internal thread groove that matches the specification of the thread. The radius and length of the screw and the screw hole are matched.

The screw rod 2 and the screw hole 2 have matching radius lengths. The thread 1 and the internal thread groove 1 are rotatably connected, thereby allowing the screw rod 1 to move, which in turn drives the extrusion plate 1 to move. The thread 2 and the internal thread groove 2 are rotatably connected, thereby allowing the screw rod 2 to move, which in turn drives the extrusion plate 2 to move, facilitating the flexible movement of the extrusion plate 1 and the extrusion plate 2.

[0015] The beneficial effects of this utility model after adopting the above technical solution are as follows: By setting up screw one, extrusion plate one, handle one, extrusion plate two, screw two, and handle two, first, hold handle two and rotate screw two clockwise, so that screw two is rotated and connected to the inner side of screw hole two, thereby pushing screw two to drive extrusion plate two to move to the left inside the clamping groove, thereby aligning the left side of the pipe with the inner wall of the left side of the clamping groove. Then, hold handle one and rotate screw one clockwise, so that screw one is rotated and connected to the inner side of screw hole one, thereby pushing screw one to drive extrusion plate one to move backward inside the clamping groove, thereby aligning and abutting the rear side of the pipe with the rear side inside the clamping groove. Then, finely adjust extrusion plate one and extrusion plate two to clamp the pipe inside the clamping groove. Cut the pipe through the cutting port. After cutting, repeat the above steps to obtain a small pipe segment with both ends aligned. The operation is simple, the failure rate is low, and maintenance is convenient.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only one aspect of the present utility model, and not all aspects. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0027] Please see Figures 1 to 4 A pipe cutting machine with an alignment structure includes: a clamping box 200, an extrusion plate 210 and a push-pull rod 230. A workbench 100 is provided below the clamping box 200. A set of push-pull slide grooves 101 are respectively opened on the left and right sides of the top of the workbench 100. A cutting opening 203 is opened on the rear side of the clamping box 200.

[0028] The clamping box 200 has a set of push-pull slides 202 on the left and right sides of the bottom, and connecting rods on the left and right sides of the front of the clamping box 200. A push-pull rod 230 is provided between the two sets of connecting rods. A screw hole 213 is provided through the left side of the front of the clamping box 200, and a screw hole 223 is provided through the center of the right side of the clamping box 200.

[0029] The screw hole 1 is equipped with a screw 211, a handle 212 is provided on the front side of the screw 211, and an extrusion plate 210 is provided on the rear side of the screw 211. The screw hole 2 is equipped with a screw 221, a handle 222 is provided on the right side of the screw 221, and an extrusion plate 220 is provided on the left side of the screw 221.

[0030] A cutting mechanism is provided between the two sets of push-pull slides 101. The position of the cutting mechanism is opposite to the position of the cutting opening 203. The thickness of the cutting mechanism matches the width of the cutting opening 203. The clamping box 200 is provided with a clamping groove 201 inside.

[0031] The clamping box 200 and the push-pull slide 202 are an integral structure, and the length, width and height of the push-pull slide 202 match the length, width and height of the push-pull slide groove 101.

[0032] The distance between the two sets of push-pull slide bars 202 is the same as the distance between the two sets of push-pull slide grooves 101. The push-pull slide bars 202 have a convex structure. The push-pull slide grooves 101 and the push-pull slide bars 202 are structurally matched. The push-pull slide bars 202 slide inside the push-pull slide grooves 101, which ensures the stability of the movement of the clamping box 200.

[0033] Extrusion plate 210 is located inside the front of clamping box 200, and extrusion plate 220 is located inside the right side of clamping box 200. Both extrusion plate 210 and extrusion plate 220 are made of rubber.

[0034] The width of the extrusion plate 210 matches the distance between the cutting opening 203 and the left inner wall of the clamping groove 201. The front side of the extrusion plate 210 is connected to the rear side of the screw 211 through a set of rotating plates 214. The rotating plates 214 are movably embedded inside the front side of the extrusion plate 210.

[0035] The width of the extrusion plate 220 matches the width of the clamping groove 201. The right side of the extrusion plate 220 is connected to the left side of the screw 221 via a set of rotating plates 224. The rotating plates 224 are movably embedded inside the right side of the extrusion plate 220. The rotating plates 214 rotate inside the extrusion plate 210 as the screw 211 rotates, thus ensuring that the extrusion plate 210 remains stationary when the screw 211 rotates and advances. The rotating plates 224 rotate inside the extrusion plate 220 as the screw 221 rotates, thus ensuring that the extrusion plate 220 remains stationary when the screw 221 rotates and advances, so that the extrusion plate 210 and the extrusion plate 220 can only move in the horizontal direction.

[0036] The screw 211 has a thread 1 on its outer side, and the screw hole 213 has an internal thread groove 1 that matches the specification of the thread 1 on its inner side. The screw 211 and the screw hole 213 have a matching radius and length.

[0037] The screw 221 has a thread 2 on its outer side, and the screw hole 223 has an internal thread groove 2 that matches the specifications of the thread 2 on its inner side. The screw 221 and the screw hole 223 have matching radius lengths. The thread 1 is rotatably connected to the internal thread groove 1, which allows the screw 211 to move, thereby driving the extrusion plate 210 to move. The thread 2 is rotatably connected to the internal thread groove 2, which allows the screw 221 to move, thereby driving the extrusion plate 220 to move, facilitating the flexible movement of the extrusion plate 210 and the extrusion plate 220.

[0038] Example 1: Please refer to Figures 2 to 4In actual use, first, grasp the push-pull rod 230 and pull the clamping box 200 forward to move it to the front of the workbench 100. Then, place the pipe into the clamping groove 201 so that the pipe is parallel to the push-pull rod 230. Next, grasp the handle 222 and rotate the screw 221 so that the outer side of the screw 221 is rotated to connect with the inner side of the screw hole 223. This causes the screw 221 to move along the screw hole 223 to the left side of the clamping groove 201 and push the extrusion plate 220 to the left. Manually bring the right end of the pipe against the left side of the extrusion plate 220. Then, by moving the extrusion plate 220 to the left, bring the left side of the pipe against the inner left wall of the clamping groove 201, aligning the left side of the pipe with the inner left wall of the clamping groove 201. At this point, it is not necessary to completely align the left side of the pipe with the inner left wall of the clamping groove 201. The left inner wall of the clamping groove 201 is tightly abutted. Then, hold the handle 212 and rotate the screw 211 to make the screw 211 rotate and connect with the screw hole 213. This causes the screw 211 to push the extrusion plate 210 to move backward inside the clamping groove 201, aligning and abutting the rear side of the pipe with the rear inner wall of the clamping groove 201. Then, finely adjust the extrusion plate 210 and the extrusion plate 220 to press the pipe tightly, thus clamping the pipe inside the clamping groove 201. At this time, the outer side of the pipe opposite the cutting opening 203 is the cutting point. Since the left side of the pipe is aligned and abutting with the left inner wall of the clamping groove 201, and the rear side of the pipe is aligned and abutting with the rear inner wall of the clamping groove 201, it is easy to cut the pipe. The structure is simple and easy to use.

[0039] Example 2: Please refer to Figures 1 to 4 After clamping the pipe, hold the push-pull rod 230 and push the clamping box 200 backward, causing the two sets of push-pull slide bars 202 to slide backward within the two sets of push-pull slide grooves 101, making the backward movement of the clamping box 200 smoother. When the cutting mechanism on the rear side of the clamping box 200 moves into the cutting opening 203, continue to push the clamping box 200 backward, so that the cutting mechanism cuts the pipe (the cutting mechanism is existing technology, and its model can be selected according to the models available on the market, which will not be described in detail). After cutting, reverse the steps in Embodiment 1 to temporarily release the pipe from the extrusion plate 210 and extrusion plate 220. After removing the first set of pipe segments that have been cut, continue adjusting screw 221 to push the left side of the remaining pipe segment with the inner wall of the left side of the clamping groove 201 and make it abut. Then adjust screw 211 to push the rear side of the remaining pipe segment backward with the inner wall of the rear side of the clamping groove 201 and make it abut. Fine adjust the first extrusion plate 210 and the second extrusion plate 220 to clamp and secure the remaining pipe segment. Repeat the cutting operation to obtain the second set of pipe segments. Repeat the above steps to obtain multiple sets of pipe segments with both ends aligned. The final effect is to ensure that the two ends of the pipe segments are aligned, thereby improving the cutting accuracy. The operation is simple and the maintenance is convenient.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
