Description

Technical Field

[0001] The utility model belongs to the technical field of punching and shearing equipment, in particular to a punching and shearing device for processing sealing gaskets. Background Art

[0002] Hardware processing encompasses multiple processes, including metal cutting, stamping, forging, welding, and surface treatment, to precisely shape various metal parts. From precision screws to large mechanical accessories, every step strives for the ultimate in craftsmanship, ensuring the durability and precise fit of the product. Specialized equipment combined with sophisticated technology meets the diverse needs of industrial manufacturing and daily life. Sealing gaskets, as a common hardware product and a key component in structural connections, ensure leak-proof and impermeable fluids or gases during transmission with their exceptional sealing properties. They are typically made of highly elastic, corrosion-resistant materials, such as rubber, silicone, or specialized synthetic materials, to accommodate diverse media and working environments.

[0003] Chinese patent publication number CN214488475U discloses a stamping device for producing optical lens gaskets. The device comprises a stamping platform topped with a punching shear and a punching die. The output end of the punching shear is mounted on a mounting plate with a positioning assembly, and a replaceable punch is mounted on the bottom of the mounting plate. A mounting bracket is bolted to the bottom of the stamping platform, corresponding to the punching die. A rotating shaft is rotatably mounted on one side of the bracket, and a guide plate is fixedly connected to the end of the shaft. An electric push rod is installed within the bracket, and a U-shaped fork is mounted on the end of the output shaft of the push rod. The U-shaped fork is sleeved onto the edge of the guide plate.

[0004] However, in the actual use of the punching and shearing device in the above-mentioned prior art, we found that there are still some shortcomings. For example, the punch on the punching and shearing machine and the punching die on the punching table are not convenient to be disassembled, replaced and used according to the processing needs. Secondly, since the raw material strip needs to pass through the punching table during punching and shearing, but due to the lack of a positioning structure, it is easy to tilt during feeding and conveying, affecting the processing and production of the product.
