Description

Technical Field

[0001] This utility model relates to the field of rivet manufacturing, specifically a forming device for manufacturing rivets. Background Technology

[0002] A rivet is a nail-shaped object used to connect two parts with through holes and a cap at one end. In riveting, the parts are connected by deformation or interference fit. Common rivets are generally manufactured by stamping. A search of application CN202420043219.9 discloses a forming device for manufacturing rivets, which includes a punch press housing, a stamping plate on the lower surface of the top plate of the punch press housing, and a worktable mounted on the lower left side of the punch press housing; first threaded rods are located on both sides of the worktable, and the inner ends of the first threaded rods are each fitted with a limit plate via bearings; second threaded rods are located on the upper surface of the limit plates, and the bottom ends of the second threaded rods are each fitted with a snap-fit ​​plate via bearings. The device is then used to form a rivet by pressing a die. The plate is placed on the upper surface of the workbench. Rotating the first threaded rod can move the limiting plate, which will squeeze the two sides of the template to limit its position. Rotating the second threaded rod can move the snap-fit ​​plate up and down. The snap-fit ​​plate will move downward to squeeze the template from above, further limiting its position. This makes it convenient for workers to use. However, the above description still has the following defects in actual use: the stability of the forming equipment is insufficient when using the screw adjustment to fix the template, and it is not easy to adjust. During the stamping process, errors can easily cause the workpiece to fly out, causing injury to the tooling personnel. Therefore, it is necessary to design a more practical forming equipment for manufacturing rivets. Utility Model Content
