A kind of cold heading equipment

Abstract

The present invention proposes a kind of cold heading equipment, including casing, driving mechanism, frame, double-wire feeding device, double-wire cutting device and upsetting device arranged on the frame and driven by the driving mechanism through the transmission mechanism. The upsetting device includes a movable block, a sliding seat arranged on one side of the movable block, a first heading head, a second heading head and a third heading head arranged on the sliding seat, and the moving block is connected to the driving mechanism through a crankshaft. , to realize the displacement of the movable block in the horizontal direction, and the sliding seat is connected with the drive mechanism through the transmission arm to realize the vertical displacement of the sliding seat relative to the movable block; it also includes an ejector device and a solid mold device for fixing the mold. The invention has high working efficiency and high production capacity.

Description

technical field [0001] The invention relates to the technical field of producing electric contact equipment, in particular to a cold heading equipment. Background technique [0002] In the electrical manufacturing industry, accessories called "contacts" are widely used in various switches, contactors, relays, and multipliers. The contacts are rivet-shaped and are used in pairs in electrical appliances. When a pair of contacts touch, the pair of contacts becomes a conductive path; when the pair of contacts separates, the pair of contacts becomes a conductive break. Historically, sterling silver has been used for contacts for a long time. With the birth of bimetal composite technology, copper and silver (including alloy) composite contacts have become mainstream accessories in the electrical manufacturing industry. Composite contacts are contacts with copper as the main material. Although the proportion of silver material is extremely low, its performance is the same as that...

AI Technical Summary

Problems solved by technology

The existing bimetallic composite cold heading machine consists of a motor, a frame, a double-wire feeding device, a double-wire cutting device, a die-moving device, an upsetting device, and an ejector device that are arranged on the frame and driven by the motor through a transmission mechanism. The upsetting device and the solid mold device used to fix the mold, the upsetting device includes initial upsetting and re-upsetting, the work efficiency is low, resulting in less production; and the upsetting head of the existing upsetting device is easy to take the stamping away from the mold , therefore, it is necessary to stop the equipment, take out the stamping parts, and then continue production, resulting in a reduction in production efficiency
