Description

Technical Field

[0001] This utility model relates to the field of rubber tube punching technology, specifically to a punching device for solid silicone rubber products. Background Technology

[0002] Silicone rubber is the most abundant type of organosilicon product. Suitable for compression molding and injection molding, it possesses excellent temperature resistance, corrosion resistance, and insulation properties, as well as good elasticity and flexibility. Its electrical and mechanical properties remain unchanged under extreme temperature and low-temperature conditions. Furthermore, it exhibits considerable resistance, enabling it to withstand acids, alkalis, solvents, chemicals, oils, and water.

[0003] There are various methods for drilling holes in silicone rubber products during production, the most common being the use of laser drilling machines and mechanical drilling tools. Existing patents, such as the polyurethane insulation pipe drilling and foaming integrated equipment with application number CN202220026746.X, relate to the field of polyurethane insulation pipe manufacturing. This utility model includes a main frame, including a base, with a support frame movably connected to the top of a connecting rod on one side of the base; a fixing mechanism, including mounting seats on both sides of the support frame and fixing components installed inside the support frame; and a drilling mechanism, including a support rod, a drill, and a drive component for controlling the movement of the drill. This utility model discloses an integrated equipment for drilling and foaming polyurethane insulation pipes. The second cylinder drives the sealing device to seal the gap between the two ends of the inner steel pipe and the outer rubber pipe. The third cylinder pulls the top fixing buckle through the connecting rod to fix the inner steel pipe and the outer rubber pipe. After starting the lifting cylinder and motor, the drill is aligned with the drilling position. The foaming gun head is placed on the fixed seat on one side of the top of the support frame. The third cylinder is started to fix the foaming gun head. Although the above patent can prevent shaking, reduce safety hazards, and improve work efficiency, it cannot adjust the laser drilling machine or drill, and cannot adjust the drilling position.

[0028] Combined with appendix Figures 1-4 A drilling device for solid silicone rubber products includes a work box 1. A limiting device 2 for restricting a solid silicone rubber tube is installed on the work box 1. The limiting device 2 includes a limiting tube 201 for mounting the solid silicone rubber tube. A support leg 202 is installed between the limiting tube 201 and the work box 1. A slotted hole 203 for drilling is formed on the limiting tube 201. A protective plate 204 is provided on one side of the limiting tube 201. A stop block 205 is installed inside the limiting tube 201. A stepping screw 206 is threadedly connected to the protective plate 204. One end of the stepper screw 206 is fixedly connected to the stop block 205. Specifically, the threaded hole opened on the guard plate 204 allows the stepper screw 206 to rotate and move within the threaded hole of the guard plate 204, which can push the stop block 205 against the solid silicone rubber tube inside the limiting tube 201 for position adjustment. The worker can hold the other end of the solid silicone rubber tube against the stop block. A fixing nut can be installed on the outside of the stepper screw 206. The fixing nut is close to the guard plate 204 and can be locked, or it can be locked by the self-locking of the stepper screw 206 and the threaded hole.

[0029] The work box 1 is equipped with a drill bit 3 for drilling holes in solid silicone rubber tubes. Specifically, this is existing technology and will not be described in detail here. The function of the drill bit 3 is to drill holes in solid silicone rubber tubes.

[0030] In specific implementation of this utility model, such as Figure 1 and Figure 3 As shown, a pushing device 4 is installed below the drilling tool 3 to push the drilling tool 3 closer to or away from the solid silicone rubber tube. The pushing device 4 includes a base 401, multiple sets of guide rods 402 installed inside the base 401, and a first telescopic rod 405 connecting to the work box 1. A slider 403 is installed on the outer side of each of the two drilling tools 3, and the slider 403 is slidably connected to the guide rod 402. A return spring 404 is installed on the outer side of the guide rod 402. The telescopic end of the first telescopic rod 405 is fixedly connected to one of the drilling tools 3. The slider 403 has a through hole 6 that cooperates with the guide rod 402. The first telescopic rod 405 can push the slider 403 to move on the guide rod 402. The slider 403 drives the drilling tool 3 to move closer to or away from the solid silicone rubber tube inside the limiting tube 201, thereby achieving the drilling effect.

[0031] In specific implementation of this utility model, such as Figure 1 and Figure 3As shown, the working box 1 is equipped with an active device 5 that pushes the rotating hole 3 to move laterally. The active device 5 includes a linear guide rail 501 between the working box 1 and the base 401 for supporting and guiding the movement. The working box 1 is equipped with a second telescopic rod 502 and the telescopic end of the second telescopic rod 502 is fixedly connected to the base 401. Specifically, the linear guide rail 501 can be a roller linear guide rail, cylindrical linear guide rail or ball linear guide rail of the prior art. It is used to support and guide moving parts. Depending on the friction properties, linear motion guide rails can be divided into sliding friction guide rails, rolling friction guide rails, elastic friction guide rails, fluid friction guide rails and other types.

[0032] Specifically, the second telescopic rod 502 and the first telescopic rod 405 are connected to the work box 1 by brackets and bolts. The second telescopic rod 502 and the first telescopic rod 405 can be pneumatic telescopic rods of existing technology. The base 401 is moved by the linear guide rail 501. The axis of movement of the base 401 is parallel to the axis of the limiting tube 201.

[0033] In specific implementation of this utility model, such as Figure 1 , Figure 3 and Figure 4 As shown, a linkage device 7 is installed between two sliders 403. The linkage device 7 includes a limit block 701 installed on the slider 403, and a limit groove 702 is formed on the limit block 701. The telescopic end of the rotating hole 3 is connected to the slider 403 with a hinged limit plate 703. The limit plate 703 is hinged in one of the limit grooves 702 and the limit plate 703 can rotate into the other limit groove 702 to achieve the limit. The limit block 701 is hinged together in the limit groove 702 of the slider 403 through a shaft and a shaft hole. When the limit block 701 is in the limit groove 702 of the slider 403, the limit plate 701 is hinged in the other limit groove 702 to achieve the limit. When 01 rotates, two results occur. First, the limiting block 701 is located in the limiting groove 702 of a slider 403, and the pushing device 4 can push a slider 403 to move, driving a hole drill 3 to drill holes in the solid silicone rubber tube. Second, after the limiting block 701 flips, the limiting block 701 connects to the limiting groove 702 of another slider 403, realizing the linkage effect of the two sliders 403. The pushing device 4 can push the two sliders 403 to move, driving the two hole drills 3 to drill holes in the solid silicone rubber tube.

[0034] Example 1:

[0035] like Figure 1As shown, the stepper screw 206 rotates and moves within the threaded hole of the guard plate 204, which can push the stop block 205 against the solid silicone rubber tube inside the limiting tube 201 to adjust its position. The worker can hold the other end of the solid silicone rubber tube. The second telescopic rod 502 drives the base 401 to move through the linear guide rail 501 to adjust the position of the hole drill 3. The limiting block 701 is located in the limiting groove 702 of a slider 403. The first telescopic rod 405 can push the slider 403 to move on the guide rod 402. The slider 403 drives the hole drill 3 to move closer to the solid silicone rubber tube inside the limiting tube 201, driving the hole drill 3 to drill holes in the solid silicone rubber tube.

[0036] Example 2:

[0037] like Figure 4 As shown, this embodiment adds a linkage device 7 compared to embodiment one. After the limiting block 701 flips, the limiting block 701 connects to the limiting groove 702 of another slider 403, realizing the linkage effect of the two sliders 403. The pushing device 4 can push the two sliders 403 to move, driving the two hole drills 3 to drill holes in the solid silicone rubber tube.

[0038] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout the text are only one of the embodiments of the present invention. The actual structure is not limited to this.
