[0002] The synthetic rubber sponge tube cutting fixture is a highly efficient device specifically designed for cutting synthetic rubber sponge tubes. Through precise cutting, it ensures consistent dimensions and shape of the sponge tube, making it suitable for various industrial applications, including the manufacture of insulation, sealing, and cushioning products. Precise cutting of the tube is typically achieved using cutting tools, saw blades, or other cutting mechanisms to meet specific size and shape requirements.
[0003] In existing technologies, pipe cutting machines for synthetic rubber sponge tubes typically place the tube directly on the workbench, and the operator controls the machine to cut it. This makes the tube prone to movement or deviation during the cutting process, leading to inaccurate and uneven cuts, and even potential breakage or damage. This affects the quality and accuracy of the cut. To address these issues, those skilled in the art have proposed a specialized fixture for cutting synthetic rubber sponge tubes. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a special fixture for cutting synthetic rubber sponge pipes, which aims to improve the existing technology of pipe cutting machines for synthetic rubber sponge pipes, where the pipe is generally placed directly on the workbench and then cut by the operator.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A special fixture for cutting synthetic rubber sponge tubes includes a mounting frame. Two linear guide rails are mounted on the inner top wall of the mounting frame. A cutter is mounted on the top of the mounting frame. A worktable is mounted on the top of each linear guide rail. Fixing blocks are fixedly connected to both the front and rear sides of the worktable. A threaded rod is rotatably connected inside each fixing block. A turntable is fixedly connected to the bottom end of the threaded rod. A guide rod is fixedly connected to the top of each fixing block.

A baffle is fixedly connected to the top of the worktable. A material pushing assembly is provided on the outside of the worktable.
[0007] Furthermore, the pushing assembly includes two mounting blocks, which are respectively fixedly connected to the front and rear sides of the worktable. A rack plate is fixedly connected inside the mounting block, a connecting block is slidably connected inside the mounting block, and a gear is rotatably connected inside the connecting block. A limit block is fixedly connected to the opposite end of each of the two connecting blocks, and a motor is fixedly connected inside the limit block. A pushing plate is fixedly connected to the adjacent end of each of the two connecting blocks.
[0008] Furthermore, the outside of the cutting tool is slidably connected to the inside of the worktable, and the outside of the guide rod is slidably connected to the inside of the threaded block.
[0009] Furthermore, the extrusion block consists of two connecting members, with the outside of the cutter slidably connected to the inside of the extrusion block.
[0010] Furthermore, the bottom end of the mold abuts against the top end of the worktable.
[0011] Furthermore, the interior of the mounting block is slidably connected to the exterior of the limiting block, and the exterior of the gear is meshing with the exterior of the rack plate.
[0012] Furthermore, the gear is fixedly connected to the output end of the motor, and the bottom end of the pusher plate abuts against the top end of the worktable.
[0013] Furthermore, a controller is fixedly connected to the front end of the fixed block on the front side, and the controller is electrically connected to the cylinder and the motor.
[0014] This utility model has the following beneficial effects:
[0015] 1. In this utility model, the turntable drives the threaded rod to rotate, the threaded rod drives the threaded block to move, the threaded block drives the cylinder to move, and the cylinder drives the extrusion block to move. This allows for convenient height adjustment of the die, thus adapting to pipes of different sizes. Furthermore, the cylinder can drive the extrusion block to move downwards, thereby fixing the die to the pipe, thereby improving cutting accuracy, enhancing cutting safety, and increasing production efficiency.
[0016] 2. In this utility model, the motor drives the gear to rotate, the gear rotates on the rack plate, the gear drives the connecting block to move, thereby driving the pusher plate to push the pipe to move, thus enabling the pipe to move automatically, thereby ensuring that the pipe maintains a consistent position and angle during the cutting process, which helps to improve the cutting precision and accuracy, and ensures that the cut is flat and the size is consistent.
[0017] 3. In this utility model, the cutting tool moves within the two extrusion blocks and simultaneously moves inside the worktable, thereby causing the linear guide rail to move the worktable while simultaneously activating the cutting tool. This ensures that the cutting tool does not deviate during the cutting process, thus guaranteeing the flatness of the pipe cut. Attached Figure Description

[0025] 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 some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Reference Figure 1 and Figure 2This utility model provides an embodiment of a special fixture for cutting synthetic rubber sponge tubes, including a mounting frame 1. Two linear guide rails 2 are installed on the inner top wall of the mounting frame 1. A cutter 3 is installed at the top of the mounting frame 1. A worktable 4 is installed at the top of the linear guide rails 2. The outside of the cutter 3 is slidably connected to the inside of the worktable 4. A baffle 13 is fixedly connected to the top of the worktable 4. Fixing blocks 5 are fixedly connected to both the front and rear sides of the worktable 4. A controller 15 is fixedly connected to the front end of the front fixing block 5. The controller 15 is electrically connected to the linear guide rails 2. The worktable 4 fixes the fixing blocks 5, so that the position of the fixing blocks 5 can be determined.
[0027] Specifically, the linear guide 2 is installed on the linear guide 2, and the cutter 3 is slidably connected to the inside of the worktable 4, so that the pipe is placed on the worktable 4. Moving the linear guide 2 will drive the worktable 4 to move, thereby moving the pipe with it. The controller 15 is set to start the operation of the linear guide 2. The baffle 13 is set to prevent the pipe from falling off the worktable 4. The cutter 3 uses a push-pull band saw rotation vertical cutting method to make the pipe cut flat.
[0028] Reference Figures 1-3 The fixed block 5 is internally connected to a threaded rod 6, the bottom end of which is fixedly connected to a turntable 7, and the top end of the fixed block 5 is fixedly connected to a guide rod 8. The threaded rod 6 is externally connected to a threaded block 9, and the guide rod 8 is externally slidably connected to the threaded block 9. A cylinder 10 is installed at the top end of the threaded block 9, and the controller 15 is electrically connected to the cylinder 10. The output end of the cylinder 10 is fixedly connected to a pressing block 11, which consists of two connecting parts. The cutter 3 is externally slidably connected to the pressing block 11, and the bottom end of the pressing block 11 is fixedly connected to both the left and right sides. The bottom end of the pressing block 12 abuts against the top end of the worktable 4.
[0029] Specifically, the fixing block 5 limits the threaded rod 6, allowing it to rotate stably. The fixing block 5 also fixes the guide rod 8, ensuring its position. The threaded block 9 is threadedly connected to the threaded rod 6 and slides on the guide rod 8, allowing the threaded rod 6 to rotate stably and move the threaded block 9. The worktable 4 and the extrusion block 11 limit the cutting tool 3, preventing it from shifting during movement. The extrusion block 11 consists of two connecting parts, with the cutting tool 3 sliding in the middle. This allows the cutting tool 3 to stably cut the pipe on the worktable 4 when the linear guide 2 moves the worktable 4. The extrusion block 11 is fixed to the die 12 with bolts, facilitating the replacement of different dies 12.
[0030] Reference Figure 1 , Figure 4and Figure 5 The worktable 4 is externally equipped with a pusher assembly 14, which includes two mounting blocks 1401. The two mounting blocks 1401 are fixedly connected to the front and rear sides of the worktable 4, respectively. A rack plate 1402 is fixedly connected inside the mounting block 1401, and a connecting block 1403 is slidably connected inside the mounting block 1401. A gear 1404 is rotatably connected inside the connecting block 1403. The outside of the gear 1404 meshes with the outside of the rack plate 1402. The two connecting blocks 1403... Limiting blocks 1405 are fixedly connected to the opposite ends of the two connecting blocks 1403. The interior of the mounting block 1401 is slidably connected to the exterior of the limiting block 1405. A motor 1406 is fixedly connected to the interior of the limiting block 1405. The controller 15 is electrically connected to the motor 1406. The exterior of the gear 1404 is fixedly connected to the output end of the motor 1406. A pusher plate 1407 is fixedly connected to the adjacent ends of the two connecting blocks 1403. The bottom end of the pusher plate 1407 abuts against the top end of the worktable 4.
[0031] Specifically, the workbench 4 fixes the mounting block 1401, thus determining its position. The mounting block 1401 also fixes the rack plate 1402, thus determining its position. The mounting block 1401 limits the connecting block 1403 and the limiting block 1405, allowing the connecting block 1403 to move stably. The connecting block 1403 also limits the gear 1404, allowing it to rotate stably. Through the meshing connection between the gear 1404 and the rack plate 1402, the gear 1404 moves on the rack plate 1402 when the motor 1406 drives it to rotate. The pusher plate 1407 abuts against the workbench 4, allowing it to stably push the pipe. The controller 15 can start the motor 1406 to operate.
[0032] Working principle: When it is necessary to cut the pipe, the linear guide 2 is activated, which drives the worktable 4 to move. At the same time, the cutting tool 3 is activated, so that the cutting tool 3 can cut the pipe on the worktable 4.
[0033] In addition, when it is necessary to fix the pipe, the cylinder 10 is activated by passing the pipe through the hole of the die 12, thereby driving the extrusion block 11 to move downward, thereby driving the die 12 to move with it, and thus the die 12 can fix the pipe.
[0034] In addition, when it is necessary to cut pipes of different sizes, the turntable 7 is rotated, which drives the threaded rod 6 to rotate, which in turn drives the threaded block 9 to move upward, which in turn drives the cylinder 10 to move, which in turn drives the extrusion block 11 to move, thereby loosening the bolts to remove the original mold 12, and then tightening the bolts to install the mold 12 that is compatible with the pipe size.
[0035] In addition, when the pipe needs to be pushed after cutting, the motor 1406 is started to operate, thereby driving the gear 1404 to rotate, which in turn causes the gear 1404 to move to the left on the rack plate 1402, thereby driving the connecting block 1403 to move as well, which in turn drives the pusher plate 1407 to move as well, so that the pusher plate 1407 can push the pipe to move.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
