A method for producing a cross-shaped guide pin and a guide pin machine

Abstract

The invention provides a method for producing a cross guide pin. The cross guide pin comprises a front end of the guide pin, a rear end of the guide pin, and a vertical end surface, wherein the vertical end surface is located between the front end and the rear end of the guide pin; a copper wire is locked with a lock mechanism which is equal to the rear end of the guide pin in width; the front end of the copper wire extends out of the front end of the lock mechanism a preset length; with the forefront end of the copper wire as a locating basis, a vertical end surface is forged from the copper wire at the position next to the front end of the lock mechanism; a segment of copper wire which is equal to the front end of the guide pin in length is reserved at the front end of the vertical end surface; and normal force is applied to the copper wire at the position close to the rear end of the lock mechanism, so that the copper wire at the position and the copper wire in the lock mechanism generate a relative displacement fracture; and the copper wire in the lock mechanism and the end surface and the front end part of the forged copper wire form the cross guide pin. The invention further provides a guide pin machine for achieving the method for producing the cross guide pin. The machining precision of the cross guide pin is improved.

Description

technical field [0001] The invention relates to the field of equipment and methods for producing guide pins, stitches or wiring pins, in particular to a method for producing cross-shaped guide pins and a guide needle machine for producing cross-shaped guide pins. Background technique [0002] As an external device, guide pins are mainly used as pins on electronic components, transistors, CPU motherboards or circuit boards. There are T-shaped pins, L-shaped pins, PIN pins, and round-headed guide pins. In the existing methods of producing guide pins, the cutting method of processing copper wires into guide pins is to use a cutting mechanism or a cutter assembly to cut the copper wires. This cutting method will inevitably bring some problems to the guide pins due to the thickness of the cutter itself. Error, and it is easy to be affected by the cutting knife and cutting speed, which will cause chipping at the ends of the two parts of the copper wire after cutting, reducing the ...
