Description

Technical Field

[0001] The utility model relates to the technical field of rubber and plastic sealing rings, in particular to a tool for cutting and forming rubber and plastic sealing rings. Background Technique

[0002] In the prior art, the method for producing rubber and plastic sealing rings is generally completed through a thermoplastic process. First, raw materials such as polypropylene or rubber are melted into a liquid state, and then, certain temperature and pressure are set in a mold for multiple hot presses to form a sealing ring. The defect of this process is that before production, a mold needs to be opened according to the shape of the sealing ring in advance. Because the cost of opening a mold is high and the cycle is long, the product size of traditional mold pressing production is unstable, and the selection of sealing ring materials is not flexible. Therefore, it is obviously uneconomical for the production of rubber and plastic sealing rings in small batches with multiple varieties. Therefore, there is a process for producing rubber and plastic sealing rings without a mold. This process method is to first produce a sealed barrel material of polyester material or rubber material by a thermoplastic process, and then, according to the requirements of the material, shape, size, etc. of the sealing ring product, use a tool to cut the sealed barrel material on a numerically controlled machine tool to produce the required sealing ring.

[0003] The tool for cutting and forming rubber and plastic sealing rings disclosed in the Chinese utility model patent application publication specification CN 10295062 A, although the rubber material is cut by a cutting knife, when cutting the rubber ring, there will be debris generated, and when cutting the rubber ring, due to the continuous rotation of the rubber ring, the rubber ring will shake, resulting in uneven cutting.

[0027] Embodiment 1

[0028] Please refer to Figures 1 to 5, the present utility model provides a technical solution: A cutting tool for cutting and forming rubber and plastic sealing rings, including a main body workbench 1. At both ends on one side of the middle part inside the workbench 1, a first motor 19 is fixedly connected. On the surface of the output shaft of the first motor 19, a first connecting rod 18 is fixedly connected. One end of the first connecting rod 18 is rotatably connected to a second connecting rod 17. One end of the second connecting rod 17 penetrates through the workbench 1 and is rotatably connected to a telescopic baffle 5. At both ends of the middle part of the top of the workbench 1, fixed shafts 32 are fixedly connected. The fixed shafts 32 are rotatably connected to the telescopic baffle 5. On one side of the top of the workbench 1, a support platform 9 is fixedly connected. At the top inside the support platform 9, a cylinder 6 is fixedly connected. One side of the piston rod of the cylinder 6 penetrates through the support platform 9 and is fixedly connected to a fixing plate 7. Inside the support platform 9, a first installation groove 16 is opened. At the middle part of the bottom end of the first installation groove 16, a rotating shaft 13 is rotatably connected. At both ends of the rotating shaft 13, gears 14 are fixedly connected. On both sides of the gears 14, a first rack 8 and a second rack 10 are respectively meshed. The first rack 8 is in contact with the fixing plate 7. One end of the first rack 8 is fixedly connected to a first spring 15. The first spring 15 is fixedly connected to the first installation groove 16. One side of the second rack 10 penetrates through the support platform 9 and is fixedly connected to a first cleaning plate 11. At the middle part of the bottom end on one side of the first cleaning plate 11, a first movable rod 23 is rotatably connected. Inside the workbench 1, a second installation groove 20 is opened. In the middle of the second installation groove 20, a rotating plate 22 is rotatably connected. The rotating plate 22 is rotatably connected to the first movable rod 23. The other end of the rotating plate 22 is rotatably connected to a second movable rod 21. One end of the second movable rod 21 is rotatably connected to a second cleaning plate 31. The top of the second cleaning plate 31 penetrates through the workbench 1. When the cutting knife cuts the rubber ring, the output shaft of the first motor 19 drives the first connecting rod 18 to rotate, thereby pushing the second connecting rod 17 to rotate, and then pushing the telescopic baffle 5 to rotate outward around the fixed shaft 32. Through the telescopic baffle 5, it blocks the debris generated by cutting, avoiding the flying of debris. After cutting, when the cylinder 6 drives the fixing plate 7 to retract, the fixing plate 7 will squeeze the first rack 8 to move inward. Due to the meshing effect of the gear 14 and the first rack 8, it can drive the rotating shaft 13 to rotate, thereby driving the second rack 10 to move leftward, and then driving the first cleaning plate 11 to move leftward. While the first cleaning plate 11 moves leftward, it pushes the rotating plate 22 to rotate through the first movable rod 23, and then through the action of the second movable rod 21, drives the second cleaning plate 31 to move rightward, so as to gather the debris on the surface of the workbench 1 together by the first cleaning plate 11 and the second cleaning plate 31, facilitating the cleaning by the staff.

[0029] Embodiment 2

[0030] Please refer to Figure 6, the present utility model provides a technical solution: A cutting tool for the cutting and forming of rubber and plastic sealing rings.

At the top end of one side of the push plate 28, a pull rod 12 is fixedly connected. On the surface of the pull rod 12, a limiting plate 27 is fixedly connected. A second spring 26 is sleeved on the surface of the pull rod 12. Between the limiting plate 27 and the third installation groove 24, there is the second spring 26. One end of the pull rod 12 penetrates through the fixed platform 2 and is rotatably connected with a pull plate 3. The pull plate 3 is in contact with the fixed platform 2. Hold the pull plate 3 and pull it outward, thereby driving the push plate 28 to move leftward, thereby driving the sliding column 30 to move leftward. Due to the cooperation of the sliding grooves, the L-shaped plate 29 is driven to rotate inward, thereby driving the arc-shaped clamping block 4 to move inward. At the same time, rotate the pull plate 3 so that the pull plate 3 abuts against the surface of the fixed platform 2, thereby fixing the arc-shaped clamping block 4, so that the arc-shaped clamping block 4 can clamp the rubber ring, avoiding the rubber ring from shaking while rotating. When the cutting is completed, make the pull plate 3 separate from the surface of the fixed platform 2. Due to the elastic action of the second spring 26, the arc-shaped clamping block 4 can be driven to move outward, thereby removing the rubber ring.
