Abstract

The invention relates to a riveting die used for a ball head rivet and a sheet metal part. The riveting die comprises an upper die and a lower die. A riveting punch used for pressing the ball head rivet and the sheet metal part for achieving riveting is arranged on the lower surface of the upper die. A clamping block assembly used for clamping and placing the ball head rivet and the sheet metal part is machined on the upper surface of the lower die. The clamping block assembly comprises a static clamping block and a movable clamping block which are in butt joint and are matched to form a riveting cavity matched with the ball head rivet and the sheet metal part. A guide hole is formed in the lower die in the horizontal direction, and a push rod moving along the guide hole is installed in the guide hole. One end of the push rod stretches out of the lower die, and the other end of the push rod is connected with the movable clamping block and drives the movable clamping block to move on the lower die. Compared with the prior art, the contact area between the ball head rivet and the clamping block assembly is large, during riveting punching, the ball head deformation of the ball head rivet is small, the size is stable, the riveting strength is also greatly improved, and the ejecting force and torsion are improved, are stable and the like.

Description

technical field [0001] The invention relates to a mold, in particular to a riveting mold used for ball rivets and sheet metal parts. Background technique [0002] Riveting is a simple and practical technical means, and it has been widely used in the company's daily production. Its advantages are light weight mold, low cost and simple process. However, for the riveting of ball rivets and sheet metal parts, if the commonly used riveting mold is used, the ejection force and torque may not meet the customer's requirements, the product stability is poor, and the quality of riveted products cannot be guaranteed. Contents of the invention [0003] The object of the present invention is to provide a riveting die for ball rivets and sheet metal parts in order to overcome the defects in the prior art. [0004] The purpose of the present invention can be achieved through the following technical solutions: [0005] A riveting die for ball rivets and sheet metal parts, comprising an ...
