Progressive die with multiple detection functions

Abstract

The invention provides a progressive die with multiple detection functions, including a closed height detection device, a strip position detection device, a feeding detection device, a lower die and an upper die, and the lower die includes a lower die base, a lower backing plate and a concave The formwork, the upper mold includes a stripping plate, a punch fixing plate, an upper backing plate and an upper mold base. The four corners of the lower mold base are provided with guide posts, and the four corners of the upper mold base are provided with guide sleeves. The closed height detection device includes a spherical probe, a spherical The top of the probe is lower than the bottom plane of the unloading plate by the thickness of a strip. Sensors are installed on the side wall of the concave formwork. The strip position detection device includes a light source emitter and an infrared receiving head. The light source emitter is fixed on the bottom of the unloading plate, and the infrared receiving head It is directly below the light source emitter and fixed on the concave mold, the feeding detection device includes an optical fiber sensor, and the optical fiber sensor is placed in the positioning pin hole of the concave mold. The progressive die with multiple detection functions described in the present invention further improves the detection function of the stamping die, reduces the scrap rate of workpieces, and saves production costs.

Description

technical field [0001] The invention belongs to the field of stamping dies, in particular to a progressive die with multiple detection functions. Background technique [0002] The mold industry is the basic industry of the national economy. The development level of the mold industry represents the industrial level and product development capability of a country. With the development of society, the pressure of competition in the mold industry is increasing, and the labor cost is getting higher and higher. Stamping mold industry The competition in China is particularly fierce. In order to survive the competition and obtain higher profits, it is urgent to update the existing technology and equipment, and process products with higher precision at the lowest cost. At present, for workpieces produced by progressive die stamping, the progressive die itself only roughly detects that each feeding is a step distance through the detection rod. After the stamping is completed, inspecto...

AI Technical Summary

Problems solved by technology

At present, for workpieces produced by progressive die stamping, the progressive die itself only roughly detects that each feeding is a step distance through the detection rod. After the stamping is completed, inspectors need to measure whether it meets the processing requirements. All relevant personnel cooperate to improve, this method is inefficient and wastes manpower, and the production cost is high
