Description
Technical Field
[0001] This utility model relates to the field of PE pipe production technology, and more specifically, to a punching and shearing device for PE pipe production. Background Technology
[0002] PE pipe, or polyethylene pipe, is made from polyethylene resin through extrusion molding. It boasts numerous advantages, including strong corrosion resistance, good flexibility, light weight, and low water flow resistance. Therefore, it is widely used in many fields such as water supply and drainage, gas transmission, and agricultural irrigation. With the increasing use of PE pipes across various industries and the growing demand for diverse specifications and shapes, various processing operations are required during the PE pipe production process to meet the installation and usage requirements of different scenarios. Punching and shearing is a crucial step in this process. Using punching and shearing tools, PE pipes can be precisely cut and perforated to manufacture PE pipe products that meet specific specifications and design requirements.
[0003] Traditional punching and shearing tools have several drawbacks when facing complex and ever-changing production demands: 1. The fixed positions of the punch and shearing blades and punching slots mean that traditional equipment cannot flexibly handle PE pipes with different diameters or different punching and shearing requirements, severely impacting production progress and product quality; 2. The disassembly of the punch and shearing blades in traditional equipment is complex, requiring specialized tools and considerable time, resulting in excessive downtime and severely affecting production continuity. Furthermore, the difficulty in disassembly makes daily maintenance of the punch and shearing blades difficult to carry out effectively, leading to a shortened lifespan and frequent replacements that further increase production costs.
[0004] Therefore, there is an urgent need for a punching and shearing device for PE pipe production to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a punching and shearing device for PE pipe production, so as to solve the problems mentioned in the background art.
[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:
[0007] A punching and shearing device for PE pipe production includes a workbench, a support frame fixedly connected to the top wall of the workbench, and a cylinder B fixedly connected to the top wall of the support frame. The device also includes:
[0008] An adjustment assembly includes a bidirectional screw rotatably connected to the outer wall of a worktable. Symmetrically distributed moving blocks are threaded onto the outer wall of the bidirectional screw. A punching and shearing seat is rotatably connected to the outer wall of each moving block. Symmetrically distributed positioning grooves are provided on the outer wall of the punching and shearing seat. A punching and shearing hole is also provided on the outer wall of the punching and shearing seat. A turntable is fixedly connected to the outer wall of the bidirectional screw, and a handle is fixedly connected to the outer wall of the turntable.
[0009] Disassemble the component and place it at the output end of cylinder B;
[0010] A linkage component is disposed on the outer wall of the movable block, and the linkage component, disassembly component and adjustment component cooperate with each other.
[0011] As a preferred technical solution of this application, the disassembly assembly includes a lifting plate fixedly connected to the output end of cylinder B, a rotating seat rotatably connected to the outer wall of the lifting plate, a uniformly distributed connecting frame slidably connected to the outer wall of the rotating seat, a cutter head frame fixedly connected to the end of the connecting frame away from the rotating seat, bolts threadedly connected to both the cutter head frame and the outer wall of the lifting plate, and symmetrically distributed punches and shears slidably connected to the outer wall of the connecting frame.
[0012] As a preferred technical solution of this application, the linkage component includes a linkage plate A rotatably connected to the outer wall of the moving block, a linkage plate B rotatably connected to the end of the linkage plate A away from the moving block, a strong tension spring fixedly connected between the linkage plate A and the linkage plate B, a guide block rotatably connected to the end of the linkage plate B away from the linkage plate A, and the guide block is slidably connected to the lifting plate, and a drive groove is provided on the outer wall of the guide block, and the drive groove is slidably connected to the punch shear.
[0013] As a preferred technical solution of this application, the outer wall of the workbench is rotatably connected to symmetrically distributed guide wheels, the outer wall of the guide wheels is rotatably connected to a guide rail, the outer wall of the guide rail is fixedly connected to a base, the outer wall of the base is fixedly connected to a cylinder A, and the output end of the cylinder A is fixedly connected to the workbench.
[0014] As a preferred technical solution of this application, the inner wall of the workbench is fixedly connected with symmetrically distributed positioning rods, and the positioning rods are located on the inner wall of the positioning groove. The outer wall of the positioning rods is slidably connected with evenly distributed adjustment blocks.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] In the scheme of this application:
[0017] 1. By using the bidirectional screw rotation in the adjustable assembly in conjunction with the linkage assembly, the position of the punching and shearing seat and the punching and shearing blades can be precisely controlled to meet the diverse punching and shearing position requirements of PE pipes. The setting of the adjusting block further optimizes the positioning of the punching and shearing seat and ensures its stability during operation. This flexible adjustment method enables the equipment to cope with various PE pipe punching and shearing tasks, improves the versatility and processing accuracy of the equipment, reduces the waste generated due to inconvenient position adjustment, and lowers production costs. It solves the problem that in the existing technology, the positions of the punching and shearing blades and punching and shearing grooves are fixed, and when it is necessary to process PE pipes with different diameters or different punching and shearing position requirements, traditional equipment cannot flexibly cope with the situation, which seriously affects the production progress and product quality.
[0018] 2. The limit on the cutter head holder can be released by rotating the bolts of the disassembly component, and the punch shears can be disassembled by sliding them on the connecting frame. This allows for quick replacement of the punch shears when they are worn or damaged, reducing equipment downtime, improving production continuity, facilitating regular maintenance and upkeep of the punch shears, extending their service life, and reducing long-term operating costs. This solves the problems of traditional punch shear disassembly methods, which are complex, require specialized tools and time, and result in excessive downtime, severely impacting production continuity. Furthermore, the difficulty in disassembly makes daily maintenance of the punch shears ineffective, leading to a shortened service life and frequent replacements that further increase production costs.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.
[0028] like Figure 1-6 As shown, the punching and shearing device for PE pipe production proposed in this embodiment includes a workbench 1, a support frame 5 fixedly connected to the top wall of the workbench 1, a cylinder B20 fixedly connected to the top wall of the support frame 5, and further includes:
[0029] The adjustment assembly includes a bidirectional screw 7 rotatably connected to the outer wall of the worktable 1. Symmetrically distributed moving blocks 8 are threadedly connected to the outer wall of the bidirectional screw 7. A punch and shear seat 9 is rotatably connected to the outer wall of the moving blocks 8. The outer wall of the punch and shear seat 9 has symmetrically distributed positioning grooves 11 and punch and shear holes 10. A turntable 18 is fixedly connected to the outer wall of the bidirectional screw 7. A handle 19 is fixedly connected to the outer wall of the turntable 18. First, the punch and shear seat 9 is rotated to rotate to a suitable angle on the moving blocks 8. Then, the handle 19 is rotated to drive the turntable 18 to rotate, which in turn drives the bidirectional screw 7 to rotate. When the bidirectional screw 7 rotates, the moving blocks 8 threadedly connected to it will move in opposite directions along the bidirectional screw 7, thereby driving the punch and shear seat 9 to move in the lateral direction of the worktable 1 and adjust it to the required punch and shear position.
[0030] Disassemble the component and install it at the output end of cylinder B20;
[0031] The linkage component is located on the outer wall of the movable block 8, and the linkage component, disassembly component and adjustment component cooperate with each other.
[0032] like Figure 5-6 As shown, in a preferred embodiment, based on the above method, the disassembly assembly further includes a lifting plate 21 fixedly connected to the output end of cylinder B20. A rotating seat 22 is rotatably connected to the outer wall of the lifting plate 21. A connecting frame 24 is slidably connected to the outer wall of the rotating seat 22. A cutter head frame 26 is fixedly connected to the end of the connecting frame 24 away from the rotating seat 22. Bolts 23 are threadedly connected to both the cutter head frame 26 and the outer wall of the lifting plate 21. A symmetrically distributed punch cutter 25 is slidably connected to the outer wall of the connecting frame 24. When it is necessary to disassemble the punch cutter 25, the bolts 23 threadedly connected to the outer wall of the lifting plate 21 of the cutter head frame 26 are unscrewed, so that the cutter head frame 26 is separated from the lifting plate 21, thereby facilitating the disassembly of the punch cutter 25.
[0033] like Figure 3-4As shown, in a preferred embodiment, based on the above method, the linkage component further includes a linkage plate A14 rotatably connected to the outer wall of the moving block 8. A linkage plate B15 is rotatably connected to the end of the linkage plate A14 away from the moving block 8. A strong tension spring 16 is fixedly connected between the linkage plate A14 and the linkage plate B15. A guide block 17 is rotatably connected to the end of the linkage plate B15 away from the linkage plate A14, and the guide block 17 is slidably connected to the lifting plate 21. A drive groove 27 is provided on the outer wall of the guide block 17, and the drive groove 27 is slidably connected to the punch and shear 25. When the position of the punch and shear seat 9 is adjusted, the movement of the moving block 8 will drive the linkage plate A14 to move, the linkage plate A14 will drive the linkage plate B15 to move, and then drive the guide block 17 to move. The punch and shear 25 will be driven to slide along the connecting frame 24 through the drive groove 27 of the guide block 17, so as to realize the adjustment of the position of the punch and shear 25 while the punch and shear seat 9 moves.
[0034] like Figure 1-2 As shown, in a preferred embodiment, based on the above method, the outer wall of the workbench 1 is further provided with symmetrically distributed guide wheels 2, the outer wall of the guide wheels 2 is rotatably connected with guide rails 3, the outer wall of the guide rails 3 is fixedly connected with a base 4, and the outer wall of the base 4 is fixedly connected with a cylinder A6. The output end of the cylinder A6 is fixedly connected to the workbench 1. When the PE pipe is punched and cut on the workbench 1, the output end of the cylinder A6 pushes the workbench 1, and the workbench 1 moves on the guide rails 3 through the guide wheels 2, thereby adjusting the position of the workbench 1 and all the above structures, that is, moving away from the PE pipe, so as to facilitate the detachment of the PE pipe.
[0035] like Figure 3 As shown, in a preferred embodiment, based on the above method, the worktable 1 is further provided with symmetrically distributed positioning rods 12 fixedly connected to the inner wall, and the positioning rods 12 are located on the inner wall of the positioning groove 11. The outer wall of the positioning rods 12 is slidably connected with evenly distributed adjusting blocks 13. The adjusting blocks 13 are moved to a reserved position for the punching and shearing seat 9 to rotate and fall into the worktable 1. When the punching and shearing seat 9 falls into the worktable 1, the positioning rods 12 are located in the positioning groove 11.
[0036] Specifically, when using this punching and shearing device for PE pipe production: first, rotate the punching and shearing seat 9 to a suitable angle on the moving block 8. Then, rotate the handle 19 to drive the turntable 18 to rotate, which in turn drives the double-headed screw 7 to rotate. When the double-headed screw 7 rotates, the moving block 8, which is threaded to it, will move in opposite directions along the double-headed screw 7, thereby driving the punching and shearing seat 9 to move in the transverse direction of the worktable 1 and adjust it to the required punching and shearing position. After the position of the punching and shearing seat 9 is adjusted, the movement of the moving block 8 will drive the linkage plate A14 to move, the linkage plate A14 will drive the linkage plate B15 to move, which in turn will drive the guide block 17 to move, and drive the punching and shearing 25 to move along the connecting frame 24 through the drive groove 27 of the guide block 17. The sliding mechanism moves the punching and shearing seat 9, simultaneously adjusting the position of the punching and shearing 25 to ensure that the punching and shearing 25 is perpendicularly aligned with the punching and shearing hole 10. Then, the adjusting block 13 is moved to a pre-reserved position for the punching and shearing seat 9 to rotate and fall into the worktable 1. When the punching and shearing seat 9 falls into the worktable 1, the positioning rod 12 is located in the positioning groove 11. The cylinder B20 is activated, and its output pushes the lifting plate 21 downwards, causing the rotating seat 22, connecting frame 24, cutter head frame 26, and punching and shearing 25 to move downwards together, punching and shearing the PE pipe. When it is necessary to disassemble the punching and shearing 25, the bolt 23 connecting the cutter head frame 26 to the outer wall of the lifting plate 21 is unscrewed, separating the cutter head frame 26 from the lifting plate 21, thus facilitating the disassembly of the punching and shearing 25.
[0037] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
