Fixing method of small punch in cold die

        1. Fix with standard fixing plate. (Of course the general punch is also standard)

　　2. The punch is standard, but the space may not be enough. Use a self-made fixing plate to fix it, and the fixing plate is fastened with screws and pins.

　　3. The punch is larger and fixed by a self-made fixed plate. The fixed plate is fastened with screws and pins, and the bottom of the punch is suspended with screws.

　　4. The punch is larger and fixed by a self-made fixing plate. The fixing plate is fastened with screws and pins, and the side of the punch is fastened with top wire.

　　 is called a cold stamping die. It is mostly a special tool installed on a press to apply a deforming force to the plate placed in it at room temperature to deform it, so as to obtain product parts with a certain shape, size and performance.

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

       1. Classification according to the nature of the process

　　 (1) Blanking die A die that separates materials along a closed or open outline. Such as blanking die, punching die, cutting die, slitting die, trimming die, cutting die, etc.

　　 (2) Bending mold A mold for bending and deforming a blank or other blank along a straight line (bending line) to obtain a workpiece with a certain angle and shape.

　　(3) The deep drawing die is a die used to make a blank sheet into a hollow part with an opening, or to further change the shape and size of the hollow part.

　　(4) Forming mold is a mold that directly replicates the blank or semi-finished workpiece according to the shape of the convex and concave molds, and the material itself only generates local plastic deformation. Such as bulging molds, necking molds, flaring molds, undulating forming molds, flanging molds, shaping molds, etc.
