Multi-station progressive die for punching of electric appliance contact support and blanking process

Abstract

The invention relates to a multi-station progressive die for punching of an electric appliance contact support and a blanking process of the multi-station progressive die. The progressive die comprises an upper die, a lower die, a work assembly and a fixed-distance positioning assembly. The work assembly comprises a punching male die, a bending shaping male die, a ribbing wedge, a cutting male die and a female die plate, wherein the punching male die, the bending shaping male die, the ribbing wedge and the cutting male die are sequentially arranged on the upper die, and the female die plate is arranged on the lower die. The female die plate is sequentially provided with a punching female die, a bending and shaping female die, a ribbing sliding block and a cutting female die, all of which are matched with corresponding work assemblies on the upper die. The fixed-distance positioning assembly is composed of a double-side-edge mechanism and a guide pin mechanism. The blanking process includes punching, bending shaping and ribbing which are sequentially conducted. Compared with the prior art, the multi-station progressive die for punching of the electric appliance contact support is wide in application range, high in production efficiency, high in manufacturing precision and convenient to maintain.

Description

technical field [0001] The invention belongs to the technical field of punching dies, and relates to a progressive die, in particular to a multi-station progressive die for stamping an electric contact support and a punching process. Background technique [0002] Stamping dies are closely related to our lives. Many daily necessities in our lives are manufactured with stamping dies. The current stamping dies are mainly divided into: single-process dies, composite dies, and progressive dies. At present, single-process molds and composite molds have several defects such as simple structure, low manufacturing precision, low production efficiency, low safety, and inconvenient maintenance, and single-process molds and composite molds are only suitable for parts with simple shapes and structures. Narrower, multi-station progressive die is the development direction of modern moulds. The number of advanced multi-station progressive dies can reach more than 50 steps. Multi-station pro...

At present, single-process molds and composite molds have several defects such as simple structure, low manufacturing precision, low production efficiency, low safety, and inconvenient maintenance, and single-process molds and composite molds are only suitable for parts with simple shapes and structures. Narrower, multi-station progressive die is the development direction of modern moulds. The number of advanced multi-station progressive dies can reach more than 50 steps. Multi-station progressive dies have huge advantages. Electrical contact supports It has a curved part and a non-bent part, and also has holes, so the multi-station progressive die for processing this part has multiple stations, and the positioning and maintenance of the strip is particularly important. The positioning of the strip is not accurate. After the processing of the position, the accuracy of the final product will be greatly reduced. When the progressive die is shut down, all the positions cannot work. If the maintenance is inconvenient, the production efficiency will be greatly reduced.
