Description

Technical Field

[0001] The utility model relates to the technical field of stamping equipment, in particular to a stamping equipment used for automobile plates. Background Art

[0002] Automotive sheet metal stamping riveting is an automotive sheet metal manufacturing technology widely used in the automotive manufacturing industry. Riveting utilizes the riveting mechanism inside the stamping equipment to pass the rivet through the sheet and firmly fix it on another sheet metal by applying pressure and rotating, forming a tight and stable connection.

[0003] The existing riveting device has limitations in design. Usually, only one set of working parts can be installed, which brings inconvenience in actual operation. Whenever the working parts need to be replaced, cumbersome disassembly and reinstallation are required, which is not only inefficient but also increases the risk of error. Therefore, the Chinese utility model patent disclosed by the existing publication number CN212191089U: a stamping equipment for automobile parts production, the application uses a slide plate to install the working parts. When the slide plate is fixed and a riveting test of a set of working parts is carried out, other working parts can be replaced, avoiding the disadvantage of stopping the machine to replace the working parts, but because the application uses a slide plate to adjust the position of three different transition rods, but because the end sizes of rivets of different sizes are also different, a suitable groove mold can accurately position and fix the rivets to prevent displacement or dislocation during the riveting process, thereby ensuring the quality and stability of the riveting, and the base plate pre-installed with rivets in the application cannot be replaced synchronously with the transition rod, so it is impossible to smoothly guide the deformation of rivets of different sizes so that they can be evenly dispersed in the connection part, thereby failing to enhance the strength and stability of the connection.
