Description

Technical Field

[0001] This invention relates to the technical field of conductive silicone polymer material punching equipment, specifically a conductive silicone polymer material punching device. Background Technology

[0002] Existing die-cutting devices for conductive silicone polymers often have simple fixing mechanisms, using only two-sided clamping. This method is not stable enough, causing the die to easily shift during production. This not only reduces production efficiency but also increases the product defect rate, affecting the stability of the production process and product quality. Furthermore, existing die-cutting devices for conductive silicone polymers often lack effective buffering designs to reduce instantaneous impact and vibration. Conductive silicone is relatively soft, and excessive impact force during die-cutting can easily cause deformation and edge fraying, leading to damage to the die and the conductive silicone product. This reduces the durability of the die and the product quality. Additionally, impact and vibration affect cutting accuracy and stability, further reducing product quality. Therefore, this paper proposes a die-cutting device for conductive silicone polymers to solve these problems. Summary of the Invention

The limiting and fixing screws 83 pass through the through holes and first limiting post holes 86 on the side of the cutting tool 84 and are threadedly connected to the fixing nuts 87.

[0020] The above scheme is adopted: the side of the cutting tool 84 has a corresponding number of through holes adapted to the first limiting post 82 according to its length, and the fixing nut 87 is adapted to the limiting fixing screw 83. The limiting fixing screw 83 passes through the through holes on the side of the cutting tool 84 and the hole 86 of the first limiting post and is threadedly connected to the fixing nut 87 to ensure that its position is stable during operation.

Four sets of second limiting post holes 122 extending to the bottom are provided on the top of the mold fixing base plate 121. Four sets of sliding grooves 123 and one set of screw grooves 124 are provided on the top of the mold fixing base plate 121. A first bidirectional screw 125 is rotatably connected inside the screw groove 124. A first drive cabinet 126 is fixedly connected to the side of the mold fixing base plate 121. A first clamping plate 127 is provided on the top of the mold fixing base plate 121. Two sets of side sliders 128 are fixedly connected below the first clamping plate 127. A set of threaded hole sliders 129; a rotating rod fixing seat 1210 and a second drive cabinet 1211 are fixedly connected above the first clamping plate 127; a guide rod 1212 and a second bidirectional screw 1213 are provided above the first clamping plate 127; a second clamping plate 1214 is provided on the side of the first clamping plate 127; clamping plate side telescopic plates 1215 are provided on both sides of the second clamping plate 1214; the rotating shaft of the first drive cabinet 126 passes through the mold fixing base plate 121 to the inside of the screw groove 124 and is fixedly connected to the first bidirectional screw 125; the side slider 128 and the slide groove 1... 23-phase matching, the threaded hole slider 129 matches the screw groove 124, the threaded hole slider 129 has a threaded hole inside that matches the first bidirectional screw 125, two sets of first clamping plates 127 are provided, the protruding part in the middle of the first clamping plate 127 matches the side groove of the punching die 13, one set of first clamping plates 127 is fixedly connected to a set of rotating rod fixing seats 1210 and a set of second drive cabinets 1211, the rotating shaft of the second drive cabinet 1211 is fixedly connected to the second bidirectional screw 1213, the other set of first clamping plates 127... Two sets of rotating rod fixing seats 1210 are fixedly connected above the plate 127. A guide rod 1212 is fixedly connected between the two sets of rotating rod fixing seats 1210. The two ends of the second clamping plate 1214 have slots inside, and the clamping plate side telescopic plate 1215 is slidably connected inside. The second limiting post hole 122 is adapted to the second limiting post 11, and the second limiting post hole 122 is slidably connected to the second limiting post 11. The inner side of the clamping plate side telescopic plate 1215 near the second bidirectional screw 1213 has a threaded hole adapted to the second bidirectional screw 1213.

[0022] The above solution, through the cooperation of the support spring 10, the second limiting post 11, and the second limiting post hole 122, effectively reduces the instantaneous impact and vibration generated during the cutting process when the die fixing mechanism 12 cuts the conductive silicone polymer material inside the punching die 13 under the pressure of the cutting mechanism 8. This protects the punching die 13 and the conductive silicone polymer material from damage, prevents the silicone material from being squeezed and deformed, and improves the cutting accuracy. The first drive cabinet 126 can drive the first bidirectional screw 125 to rotate, thereby driving the two... The first clamping plates 127 move inward or outward simultaneously. By adjusting the first drive cabinet 126, the protruding parts of the two sets of first clamping plates 127 can clamp the grooves on both sides of the punching die 13. At this time, the side extension plates 1215 of each set of second clamping plates 1214 will also retract or expand. Then, by driving the second drive cabinet 1211 to drive the second bidirectional screw 1213 to rotate, the two sets of second clamping plates 1214 move inward or outward simultaneously, clamping the other two sides of the punching die 13, thus completing the complete and stable fixation of the punching die 13.

[0023] The working principle of this invention is as follows: The operator first places the punching die 13 on the die fixing base plate 121 of the die fixing mechanism 12, and places the conductive silicone polymer material to be punched inside the punching die 13; by operating the first drive cabinet 126, the first bidirectional screw 125 is driven to rotate, thereby driving the two sets of first clamping plates 127 to move inward or outward at the same time, so that the protruding parts of the two sets of first clamping plates 127 clamp the grooves on both sides of the punching die 13. At this time, since the clamping plate side telescopic plates 1215 on both sides of the second clamping plate 1214 can extend and retract, they will automatically adjust according to the size of the die. At this time, by operating the second drive cabinet 1211, the second bidirectional screw 1213 is rotated, thereby driving the two sets of second clamping plates 1214 to move inward or outward at the same time, further fixing the die. Through the combination of two sets of bidirectional screws and four sets of clamping plates, the die can be fixed quickly, stably and accurately, which greatly improves the production efficiency of punching conductive silicone polymer material, and at the same time reduces the product defect rate caused by die displacement. After the mold is fixed, a suitable cutting tool 84 can be selected according to the size, length and width of the cutting opening on the mold. The side of the cutting tool 84 has a corresponding number of through holes that match the first limiting post 82 according to its length. The limiting fixing screw 83 passes through the through holes on the side of the cutting tool 84 and the hole 86 of the first limiting post and is threadedly connected to the fixing nut 87 to ensure that its position is stable during operation. This design allows for quick replacement of cutting tools 84 of different lengths and thicknesses. The quick replacement and stable fixing of the cutting tool 84 makes production flexible to adapt to different specifications and shapes of conductive silicone polymer material punching molds, improving the versatility of the equipment and production efficiency. After the cutting tool 84 is fixed, the cylinder 4 is activated, pushing the push rod 5 and the lower pressure plate 6 downward. Since the limiting sliding hole 7 above the lower pressure plate 6 is slidably connected with the support sliding rod 2, the lower pressure plate 6 is ensured to move stably in the vertical direction. The cutting mechanism 8 then presses down, and the cutting tool 84 begins to punch the conductive silicone polymer material in the punching die 13. During this process, the cooperation of the support spring 10 below the die fixing mechanism 12, the second limiting post 11, and the second limiting post hole 122 plays a key buffering role. They can effectively reduce the instantaneous impact and vibration generated during the cutting process, prevent the conductive silicone from being deformed by impact and squeezing, and prevent edge fuzzing, thus protecting the punching die 13 and the conductive silicone product from damage. This buffering design not only protects the die and the conductive silicone workpiece, but also improves the cutting accuracy and stability, ensuring product quality. After the blanking is completed, the cylinder 4 retracts, driving the cutting mechanism 8 to rise. At the same time, the mold fixing mechanism 12 returns to its initial position under the action of the support spring 10. The operator can then take out the blanked conductive silicone polymer product for further processing.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
