Rapid continuous feeding stamping method of welding pin

Abstract

The invention discloses a rapid continuous feeding stamping method of a welding pin. The rapid continuous feeding stamping method is characterized in that a male die positioned above a female die and the female die under the male die are provided; a concave pit matched with the male die is formed in the female die; a bottom die matched with the male die is mounted in the concave pit, and is mounted on the female die by a spring; the bottom die sinks in the female die after the spring is compressed; a limiting block and a material placement platform that are positioned on the two sides of the bottom die respectively are mounted on the female die; continuous grooves are formed in the female die, the bottom die, and the inner wall, close to the limiting block, of the concave pit; the grooves extend to form material clamping grooves in the material placement platform; the grooves are formed in the bottom surface of the male die; and the grooves in the bottom surface of the male die extend along the side surface, opposite to the limiting block, of the male die. Compared with the traditional copper product electroplating mode, the rapid continuous feeding stamping method of the welding pin saves the production time greatly and reduces the production cost greatly; the structure is simple; the operation is convenient; and in a cutting process, a steel wire material is positioned in the same state all the time, so that the efficiency and the product yield are improved and increased.

Description

technical field [0001] The invention relates to a mold used in the sensor manufacturing industry, in particular to a rapid continuous feed punching method for welding pins. Background technique [0002] The automobile wheel speed sensor is mainly composed of induction head, wiring harness and accessories. The role of the induction head is to cooperate with the target gear installed on the chassis of the car to measure the speed of the car wheel, which is composed of coils, magnetic poles and other parts. On this basis, to ensure the normal operation of the sensor, the sensor must be properly installed on the chassis of the car, and there are many ways to install it. Now commonly used a kind of wheel speed sensor is to rely on the outer steel casing of the induction head to cooperate with a part, i.e. the elastic bush, and pack into the corresponding mounting hole of the chassis. When designing the sensor, it is necessary to combine the magnetic steel and the magnetic condu...
