Description
Technical Field
The invention belongs to the field of automatic production of stranded wire contact pins, and particularly relates to double-path production equipment for stranded wire contact pins.
Background
The twisted elastic pin (commonly called twist needle) is formed by reversely twisting two layers of stranded copper wires, the two ends of the twisted elastic pin are welded into a bundle, one end of the twisted elastic pin is pressed into a sleeve, and the other end of the twisted elastic pin is upset and raised. Generally, the method comprises the steps of automatically and finely straightening twisted beryllium copper stranded wires (the common specification is 0.40mm in diameter), cutting the beryllium copper stranded wires to a fixed length, and automatically performing laser fusion welding on two ends. In the traditional process, the cutting process and the welding process are manually finished on two devices respectively, so that the yield and the rate of finished products are low. The company has therefore designed a variety of automated devices to improve production efficiency, such as: an automatic cutting and welding integrated machine for twisted wire pins (application number 201822217138.3), an automatic cutting and welding device for twisted wire pins (201910073877.6), an automatic production machine for twisted wire pins (201811610829.8), a full-automatic cutting machine for twisted wire pins (201920095301.5) and the like.
