Description

A double piercing terminal mold

technical field

The utility model relates to a mold, in particular to a double piercing type terminal mold. the

Background technique

Stamping die refers to a special process equipment for processing metal or non-metallic materials into parts in cold stamping processing. Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation to obtain the required parts.

There are many forms of stamping dies, which can generally be classified according to the following main features:

1. Classified according to the nature of the process

Blanking Die: A die that produces separation of material along closed or open contours. Such as blanking die, punching die, cutting die, notch die, trimming die, cutting die, etc.

Bending die: A die that bends a sheet blank or other blank along a straight line (bending line) to obtain a workpiece with a certain angle and shape. the

Drawing die: It is a mold that makes the sheet blank into an open hollow part, or further changes the shape and size of the hollow part.

Forming mold: It is a mold that directly copies the rough or semi-finished workpiece according to the shape of the convex and concave molds in the figure, and the material itself only produces local plastic deformation. Such as bulging die, shrinking die, expanding die, undulating forming die, flanging die, shaping die, etc.

2. Classified according to the degree of process combination

Single-process mold: In one stroke of the press, only one stamping process is completed.

Composite mold: There is only one station, and in one stroke of the press, two or more stamping processes are simultaneously completed at the same station.

Progressive die: also known as continuous die, refers to the feeding direction of the blank, with two or more stations, in one stroke of the press, two or more steps are completed successively at different stations Die for stamping process.

The double piercing terminal requires that the sheath of the conduction cable be cut through the sharp corner of the terminal when the finished product is assembled, so as to achieve conduction and data transmission. the
