Problems solved by technology

However, this process has the following disadvantages: 1) It is easy to desolder and the strength is not good, because once there is a deviation in the welding or pores are generated during the welding process, the welding strength is insufficient, and the weld is easy to crack under the premise of load torque
2) The stability is poor, because manual welding is easy to produce eccentricity between the stamping part and the nut, and the stability is poor
3) The production efficiency is low, and it takes a long time to artificially weld the circle of the nut

Abstract

The invention discloses a nut punching and riveting mold with high stamping efficiency and good riveting effect. There is a stepped through hole with a large upper part and a smaller one at the lower part. A stepped shaft-shaped ejector pin is pierced through the stepped through hole. A nitrogen spring for pushing the ejector pin is provided in the upper mounting seat, and an adsorption nut is provided at the bottom of the riveting punch. The ring magnet is provided with a riveting die set in the lower die base, a waste material discharge hole is arranged in the riveting die set, and at least two positioning pins for positioning workpieces are arranged on the lower die base.

Description

technical field [0001] The invention relates to a nut stamping and riveting die. Background technique [0002] When nuts are set on the stamped plate for connection, the plate and the nut are connected by spot welding first, and then the stamped plate and the nut are positioned with a professional fixture, and then welded to connect the two as a whole. However, this process has the following disadvantages: 1) It is easy to desolder, and the strength is not good, because once there is a deviation in the welding or pores are generated during the welding process, the welding strength is insufficient, and the weld is easy to crack under the load torque premise. 2) The stability is poor, because manual welding is easy to produce eccentricity between the stamping part and the nut, and the stability is poor. 3) The production efficiency is low, and it takes a long time to artificially weld the circle of the nut. Contents of the invention [0003] The technical problem to be sol...
