Abstract
Description
Technical Field
[0001] This utility model relates to the field of rubber seal cutting technology, and in particular to a cutting device for rubber seal production. Background Technology
[0002] Rubber seals are round rubber products used for leak prevention, typically found at pipe joints. They possess high elasticity and good mechanical strength. At room temperature, they exhibit good elasticity, slight plasticity, and excellent electrical insulation properties. Rubber seals are usually made of natural rubber, a material that generates little heat during repeated deformation, has good flexural resistance, and is a non-polar rubber, thus possessing good electrical insulation properties.
[0003] As disclosed in CN214818732U, a cutting device for producing rubber seals includes a worktable. An extrusion mechanism is installed on both sides of the top of the worktable. The extrusion mechanism includes a fixed plate, a rotating plate, a guide plate, an auxiliary roller, a connecting rod, fastening bolts, a snap-fit plate, and an L-shaped groove. Fixed plates are symmetrically welded to both sides of the top of the worktable. The inner sides of the two fixed plates are installed on both sides of the rotating plate. This invention features an extrusion mechanism. The L-shaped groove facilitates the snap-fit placement of the connecting rod. The fastening bolts and snap-fit plate allow the guide plate to move as the snap-fit plate rotates, thus facilitating adjustment for rubber seals of different thicknesses. This facilitates the extrusion of the rubber seal, ensuring its flatness during cutting. Simultaneously, the auxiliary rollers facilitate the limitation and movement of the rubber seal.
[0004] However, in the aforementioned patent, when the blade cuts the rubber part, the cut of the rubber part cannot be fixed during the downward movement of the blade, which easily causes the cut to be crooked. Therefore, a cutting device for the production of rubber seals is needed. Utility Model Content
[0005] The purpose of this utility model is to provide a cutting device for the production of rubber seals, which solves the problem that the cut of the rubber part cannot be fixed during the downward movement of the cutting tool, which easily causes the cut to be crooked.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for producing rubber seals, comprising a hydraulic cylinder, a housing component for fixing the hydraulic cylinder, and a moving block fixedly connected to the output shaft at the bottom of the hydraulic cylinder and sliding up and down along the interior of the housing component. A buffer component is fixedly connected to the bottom of the moving block, and a pressing plate is provided at the bottom of the moving block. A support component is provided between the moving block and the pressing plate, sliding along the periphery of the buffer component. A stabilizing rod is fixedly connected to the top of the pressing plate, and the top of the support component slides along the periphery of the buffer component to move the pressing plate away from the moving block.
[0007] Preferably, the support component includes a fixing member, a connecting rod, and a moving member. The fixing member and the moving member are connected by the connecting rod. The top of the moving member is provided with a positioning strip that is slidably connected to the bottom of the moving block. The interior of the moving member is provided with a groove that slides along the periphery of the buffer component.
[0008] Preferably, the buffer component includes a fixed post, a sliding rod, and a spring. The spring is located along the axial direction of the sliding rod, which is fixedly connected to the outer wall of the fixed post. The top of the fixed post is connected to the bottom of the moving block.
[0009] Preferably, the movable block includes a movable column, a sliding groove, and a limiting groove. The bottom of the movable column has a sliding groove extending along the axis of the stabilizing rod, and the limiting groove is symmetrically arranged on the bottom surface of the movable column about the sliding groove.
[0010] Preferably, the housing component includes a fixed housing, a support plate, and a cutting table. The fixed housing and the cutting table are connected by the support plate, which is symmetrically arranged on both sides of the fixed housing about the hydraulic cylinder.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] When the moving block inside the housing component is moved by the hydraulic cylinder, the pressing plate first contacts the rubber part placed on the cutting table. Then the moving block will continuously approach the pressing plate. At this time, the supporting component is subjected to pressure and rotates, causing its top to slide along the outer wall of the buffer component. This causes the spring set on the outer wall of the sliding rod to contract and provide buffering force. Then, the cutting blade, which is fixedly connected to the bottom of the moving block, passes through the pressing plate and cuts the rubber part pressed by the pressing plate. This can ensure the stability of the cutting, ensure its cutting accuracy, and prevent uneven cutting parts. Attached Figure Description

[0020] 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.
[0021] This utility model relates to a cutting device for producing rubber seals, such as... Figure 1-6 The device includes a hydraulic cylinder 1, a housing component 2 for fixing the hydraulic cylinder 1, and a movable block 3 that is fixedly connected to the output shaft at the bottom of the hydraulic cylinder 1 and slides up and down along the inside of the housing component 2. A cutting tool 4 for cutting rubber parts is fixedly connected to the bottom center of the movable block 3. A buffer component 6 is fixedly connected to the bottom of the movable block 3 and is symmetrically arranged on the bottom surface of the movable block 3 about the cutting tool 4. A support component 5 is slidably connected to the periphery of the buffer component 6 along its axial direction. The movable block 3 is connected to the pressing plate 8 through the support component 5. The bottom surface of the movable block 3 is provided with an extension groove for a stabilizing rod 7 fixed to the top of the pressing plate 8 to stabilize the proximity between the movable block 3 and the pressing plate 8.
[0022] Among them, such as Figure 3As shown, the housing component 2 includes a fixed housing 21, and a support plate 22 is fixedly connected to one side of the fixed housing 21. The support plate 22 is symmetrically arranged on both sides of the fixed housing 21 about the hydraulic cylinder 1. The fixed housing 21 is fixedly connected to the cutting table 23 through the support plate 22.
[0023] Furthermore, such as Figure 4 As shown, the support component 5 includes a connecting rod 52. A fixing member 51 is rotatably connected to the bottom end of the connecting rod 52, and a moving member 53 is rotatably connected to the top end of the connecting rod 52. A positioning strip 55 is fixedly connected to the top of the moving member 53. The fixing member 51 and the moving member 53 are connected via the connecting rod 52. The connecting rod 52 drives the moving member 53 to move around the fixing member 51. The bottom of the fixing member 51 is fixedly connected to the top of the pressing plate 8. Figure 5 As shown, the buffer component 6 includes a sliding rod 62, a baffle 63 is fixedly connected to the middle circumference of the sliding rod 62, a spring 64 is provided on the outer wall of the sliding rod 62 and fixed to one side of the baffle 63, one end of the sliding rod 62 is fixedly connected to the fixed post 61, and the top of the fixed post 61 is fixedly connected to the bottom of the moving block 3.
[0024] Furthermore, such as Figure 3 As shown, the movable block 3 includes a movable column 31. The bottom of the movable column 31 is provided with a sliding groove 32 extending along the axis of the stabilizing rod 7. The bottom of the movable column 31 is provided with a limiting groove 33 symmetrically disposed on the bottom surface of the movable column 31 with respect to the sliding groove 32.
[0025] Among them, such as Figure 2-6 As shown, when the moving block 3 approaches the pressing plate 8, the connecting rod 52 rotates, causing the groove 54 in the moving part 53 to slide along the periphery of the sliding rod 62, causing the spring 64 to retract toward the baffle 63, providing support for the moving part 53, and achieving the effect of the supporting part 5 and the buffering part 6 working together between the moving block 3 and the pressing plate 8 to provide a buffering effect.
[0026] In practical use: When the moving block 3 inside the housing component 2 is moved by the hydraulic cylinder 1, the pressing plate 8 first contacts the rubber part placed on the cutting table 23. Then the moving block 3 will continuously approach the pressing plate 8. At this time, the supporting component 5 is subjected to pressure and rotates, causing its top end to slide along the outer wall of the buffer component 6. This causes the spring 64 set on the outer wall of the sliding rod 62 to contract and provide buffering force. Then, the cutting blade 4, which is fixedly connected to the bottom of the moving block 3, passes through the pressing plate 8 and cuts the rubber part pressed by the pressing plate 8. This can ensure the stability of the cutting, ensure its cutting accuracy, and prevent uneven cutting parts.
