Wiring terminal progressive stamping die

Abstract

The invention relates to a wiring terminal progressive stamping die. According to the wiring terminal progressive stamping die, a wiring terminal is manufactured through copper tubes, the die comprises an upper die plate, a lower die plate and a guide pillar and guide sleeve structure arranged between the upper die plate and the lower die plate; a leveling station and a punching cutting station are sequentially arranged between the upper die plate and the lower die plate in the horizontal direction, the lower end face of an upper die plate part of the leveling station is sequentially provided with a first upper movable die, a first upper stamping die and a second upper movable die from front to back, and correspondingly, the upper end face of a lower die plate part is sequentially provided with a first lower stamping die, a lower movable die and a second lower stamping die from front to back; the lower end face of an upper die plate part of the punching cutting station are sequentially provided with a third upper movable die, and correspondingly, a third lower stamping die is arranged on the upper end face of the lower die plate. The wiring terminal progressive stamping die has the advantages that operation on the leveling station and operation on the punching cutting station are completed synchronously, only one time of stamping is needed, the production efficiency of products is improved, and raw materials can be saved.

Description

technical field

[0001] The invention relates to a die, in particular to a progressive stamping die for a terminal. Background technique

[0002] Terminals are also called copper noses, wire noses, copper wiring noses, copper pipe noses, aluminum noses, etc. Terminals are connectors used to connect wires and cables to electrical equipment. After the wire and cable copper aluminum core.

[0003] The wiring terminal has the characteristics of thin material, complex shape, many bending parts, high precision requirements, slender shape, and large demand. In the manufacturing process of the wiring terminal, it is usually made by copper tube stamping process. The stamping process mainly includes cutting , chamfering, flattening, and punching four processes, a total of four stampings are required. Its disadvantages are: low production efficiency and low material utilization. Contents of the invention
