[0003] The punching die will generate friction when it contacts and impacts the accessories. If the friction is too large or the working speed is too fast, the friction heat will accumulate in a short time and cause the die to overheat. However, some current punching devices for automotive accessories cannot cool down the die during use. When facing high-frequency and high-intensity punching operations, the die will quickly heat up and overheat. Overheating may cause the die to deform or be easily damaged, affecting the accuracy and stability of the punching process, and thus affecting the quality of the punching operation.

[0004] At the same time, due to the characteristics of some accessory materials, the accessories are prone to adhesion to the mold during punching. Some existing automobile accessory punching devices cannot prevent adhesion between the accessories and the mold during use, resulting in the need for workers to frequently stop the machine for manual intervention on the accessories, greatly affecting work efficiency. In addition, iron filings will be generated during punching. If they are not cleaned in time, the surface of the accessories will be damaged during subsequent punching operations.

The center of the bottom plate 6 is designed as a through hole. Through the through hole of the bottom plate 6, the waste generated during the punching can fall from the bottom of the bottom die seat 7 into the inner cavity of the workbench 1. The inner cavity of the workbench 1 is slidably connected with a collection box 10, and the collection box 10 can uniformly collect and process the fallen waste. A cooling mechanism 8 is provided on one side of the workbench 1. The cooling mechanism 8 can ventilate and cool the surface of the bottom die seat 7 and the punching column 5. By lowering their temperature, the thermal stress and wear during use can be reduced. The service life of the mold can be extended, and the thermal expansion and deformation of the mold can be reduced, thereby improving the accuracy and consistency of punching and ensuring the accuracy of the punching aperture. A lifting mechanism 9 is provided on the top of the bottom plate 6. The lifting mechanism 9 can reduce the adhesion of the accessories to the surface of the bottom mold seat 7 after the accessories are punched. Baffles 12 are fixedly connected on both sides of the inner wall of the inverted U-shaped frame 2. When the accessories adhere to the surface of the punching column 5 after punching, the accessories can be prevented from adhering to the punching column 5 and rising under the blocking effect of the baffles 12 on both sides. The lifting mechanism 9 is used in conjunction with the baffle 12 to reduce the friction between the accessories and the mold during punching. The adhesion situation occurs, thereby effectively reducing the downtime for maintenance, and further reducing the need for manual intervention, which can not only reduce the burden on operators, but also improve the efficiency and safety of production operations.

The surface of the side plate 14 is fixedly connected to the surface of the workbench 1 and the side plate 14 through a plurality of pipe clamps. One side of the side plate 14 is fixedly connected to a wind shell 83. The wind shell 83 corresponds to the position of the bottom mold base 7. The wind shell 83 is connected to the wind duct 82. 83 is used in conjunction with the chip collection mechanism 11. When in use, the high-pressure airflow generated by the blower 81 will be transported through the air duct 82 and finally discharged from the wind shell 83, thereby effectively reducing the temperature of the bottom mold base 7 to prevent it from overheating during high-intensity and high-frequency operation, thereby improving its service life and stability. Another air outlet of the blower 81 is provided with an auxiliary component 84, which can perform pneumatic cooling on the surface of the punching column 5 to avoid thermal expansion of the surface of the punching column 5 due to overheating, thereby ensuring the accuracy and stability of the punching.

[0023] The auxiliary component 84 includes a telescopic hose 841, one end of which is connected to the air outlet of the blower 81, and one side of the bottom plate 6 is fixedly connected to a duct 842 by a pipe clamp, and one end of the duct 842 is connected to a nozzle 843, and the nozzle 843 is designed to be inclined. The bottom end angle of the nozzle 843 corresponds to the position of the punching column 5, and the other end of the duct 842 extends to the outside of the workbench 1 and is connected to the telescopic hose 841. When in use, the high-pressure airflow blown out by the blower 81 will be transported by the telescopic hose 841 and the duct 842, and finally blown out by the nozzle 843 to perform precise pneumatic cooling on the surface of the punching column 5, which can effectively reduce the thermal expansion problem caused by overheating of the punching column 5, thereby improving the quality and work efficiency of punching. It is connected to a support rod seat 845, which includes three support rods and circular ring seats fixedly connected at both ends of the support rod seat 845, the circular ring seat at the top of the support rod of the support rod seat 845 is fixedly connected to the surface of the air duct 842, and a plug-in rod seat 844 is slidably connected below the surface of the telescopic hose 841, the plug-in rod seat 844 includes three plug-in rods and circular ring seats fixedly connected to their bottom ends, the circular ring seat at the bottom of the plug-in rod seat 844 is fixedly connected to one side of the workbench 1, the plug-in rod seat 844 corresponds to the position of the support rod seat 845, one end of the plug-in rod of the plug-in rod seat 844 passes through the top of the slip ring seat of the support rod seat 845 and is slidably connected to the inner wall thereof, when the hydraulic push rod 3 drives the punching column 5 to move, the support rod of the plug-in rod seat 844 can be lifted up and down along the circular ring seat with the support rod seat 845, thereby enabling the telescopic hose 841 to maintain a stable moving path during lifting.

[0024] The lifting mechanism 9 includes an inner shell 91, which is fixedly connected to the top of the bottom plate 6. The surface of the inner shell 91 is slidably connected to a top shell 92.

The bottom end of the compression spring 93 is fixedly connected to the top of the bottom plate 6. Under the action of the compression spring 93, the height of the top shell 92 can be higher than the height of the bottom die seat 7. When in use, the accessory to be punched is placed on the top of the top shell 92. When the punching column 5 contacts and squeezes the accessory downward, the top shell 92 can be moved downward to compress the compression spring 93. At this time, the bottom die seat 7 will be lifted from the top shell 9. 2 is exposed at the center through hole to cooperate with the punching operation, and when the punching is completed, the accessories on the top of the top shell 92 can be bounced up under the action of the compression spring 93, thereby reducing the situation where the accessories stick to the surface of the bottom mold base 7, and the surface of the inner shell 91 is fixedly connected with a plurality of slide posts 94, and the inner wall of the top shell 92 is provided with a plurality of slide grooves 95, and the number and shape of the slide posts 94 and the slide grooves 95 correspond to each other, and the slide posts 94 are slidably connected with the slide grooves 95. Under the cooperation of the shapes of the slide grooves 95 and the slide posts 94, the sliding of the top shell 92 and the inner shell 91 can be kept stable, and the separation of the top shell 92 and the inner shell 91 can be avoided.

[0025] The chip collecting mechanism 11 includes a mounting shell 111, which is located on one side of the top of the workbench 1, and both sides of the mounting shell 111 are fixedly connected to the side plates 14 on both sides. A plurality of exhaust fans 112 are installed on the side of the inner cavity of the mounting shell 111 away from the bottom mold base 7, and a support frame 113 is fixedly connected to the side of the inner wall of the mounting shell 111 close to the bottom mold base 7. A filter plate 114 is slidably connected to the inner wall of the support frame 113, and the filter plate 114 can intercept and filter iron chips. A maintenance slot is provided on the top of the mounting shell 111, and the filter plate 114 can be pulled out for cleaning and replacement through the maintenance slot. When the exhaust fan 112 draws air, the iron chips on the top of the workbench 1 can be driven by the airflow Moving them to the surface of the filter plate 114 for interception and collection can avoid damage to the surface of subsequent punching accessories due to untimely cleaning of iron filings. At this time, in conjunction with the airflow blown out by the wind shell 83, the collection effect of iron filings can be further improved. Through the connection between the side panel 14 and the inner shell 91, a surrounding structure can be formed on the top of the workbench 1 to reduce the flying of iron filings. A through groove 13 is provided on the side of the top of the workbench 1 close to the mounting shell 111, and the through groove 13 is connected to the inner cavity of the workbench 1. The heavier iron filings can fall into the collection box 10 through the through groove 13 for collection and processing, which can reduce the burden of filtering and intercepting iron filings by the filter plate 114.

[0026] It is worth noting that the telescopic hose 841 proposed in this technical solution is a prior art, and its working principle and beneficial effects when used are not described in detail here.

[0027] Working principle: first, place the accessories to be punched on the top of the top shell 92, and then start the hydraulic push rod 3 to drive the mounting plate 4 and the punching column 5 to move downward, so that the punching column 5 contacts and squeezes the accessories, and the top shell 92 can move downward to compress the compression spring 93, and then the bottom die seat 7 will appear from the central through hole of the top shell 92 to cooperate with the punching, and when the punching is completed, under the action of the compression spring 93, the accessories on the top of the top shell 92 can be bounced up, which can reduce the situation where the accessories stick to the surface of the bottom die seat 7. If the accessories stick to the surface of the punching column 5, the baffle 12 can also be used to prevent the accessories from sticking to the surface of the punching column 5. Accordingly, the accessories can be prevented from sticking to the surface of the punching column 5 or the bottom die seat 7. When it is necessary to cool down the punching column 5 and the bottom mold seat 7, first start the blower 81 to generate a high-pressure airflow, which is transported by the air duct 82 and discharged by the wind shell 83, which can effectively reduce the temperature of the bottom mold seat 7. At the same time, the high-pressure airflow generated by the blower 81 will also be transported by the telescopic hose 841 and the air duct 842, and finally blown out by the nozzle 843 to perform precise pneumatic cooling on the surface of the punching column 5, thereby reducing overheating of the surface of the punching column 5 and the bottom mold seat 7. Finally, when it is necessary to clean the iron filings, start the exhaust fan 112 to exhaust air. With the cooperation of the airflow blown out by the wind shell 83, the iron filings generated during punching can be cleaned in time, avoiding damage to the surface of the accessories during subsequent punching due to untimely cleaning of the iron filings.
