One-time forming device for high-speed cold heading of nuts

Mechanical basic parts technology: one-time forming device for high-speed cold heading of nuts

Usually used to make the head of screws, bolts, rivets, etc. Can reduce or replace cutting processing. At present, mechanical and electrical products have been very popular as living and household equipment, and the movable nut is a kind of nut widely used in mechanical and electrical appliances. Existing movable nuts are all processed by hot or cold heading into flange blanks and processed by lathes. In the middle, the movable nuts need to be transferred and placed and fixed for many times. The operation procedures are cumbersome and easy to produce processing errors. .

Mechanical basic parts technology: Nut high-speed cold forging one-time forming device (Guide: What are the benefits of cold forging? Fastener cold forging forming process analysis)

Working process:

By combining the front punch forming die 1, the buffer spring 2, the adjusting seat 3, the inner hole forming die 4, the inner hole forming punch sleeve 5, the forming die pad 6, the thimble 7, the spring 8, and the screw 9, through The optimization of the experiment enables the movable nut to be directly cold-headed to produce a suitable special-shaped surface in the process of cold forging into the flange blank, which eliminates the trouble of reprocessing on the lathe, and at the same time, the strength of the cold-headed movable nut is greatly improved. Convenient operation and high production efficiency.
