Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of mold manufacturing, and specifically relates to a rivet die. BACKGROUND

[0002] The rivet die is a die specially designed for producing or processing rivets, which can shape metal materials into rivets with specific shapes and sizes under pressure. In addition, in the riveting process, the rivet die is also commonly used for positioning and fixing rivets to ensure the accuracy and stability of the riveting process.

[0003] A rivet die in a mold is disclosed in Chinese Patent No. CN211413545U, with an application date of December 11, 2019. The patent technology extends the hydraulic rod, which drives the pressing block to move downward, and the live worker pressing die moves downward. The pressing plate of the pre-pressing assembly first presses the workpiece. At this time, the pressing die continues to move downward, the third spring elastic force acts, and the workpiece is pressed tightly to avoid direct stamping causing the workpiece to be stressed and skewed, thereby improving the quality of stamping. The rivet block first presses the top of the rivet. As the pressing die moves downward, the first spring is compressed, and the pressure gradually increases until the bottom of the baffle is pressed by the block. With the pressure effect, the workpiece is riveted, and positioning is performed in advance to prevent the rivet from moving during the riveting process, resulting in poor rivet quality or rivet failure. However, after the metal block is stamped and formed by the above-mentioned device, the distance between the upper and lower molds is small, which makes it inconvenient to take out the rivet forming piece at the top of the lower mold and inconvenient to place the metal block for rivet forming on the appropriate position on the surface of the lower mold, thereby affecting the production efficiency.
