The blank holder of metal stamping die is mainly a pressing device designed to prevent stamping and drawing products from wrinkling in the drawing process. The variable blank holder control is realized through the blank holder, which can greatly reduce the cost and has strong practicability
Stamping and drawing parts
1，Blank holder is a kind of pressing part on the die used in metal stamping and drawing processing, and its function is to prevent the wall or flange of the workpiece from wrinkling in drawing

2，Structure

It mainly includes an upper layer, a small top column, and a lower layer. The upper layer is made of elastic materials. The upper layer is made of elastic material, the upper layer is in contact with the flange area of the slab, and the lower layer is connected with the ejector rod. A plurality of small ejectors are embedded between the upper layer and the lower layer through sinking grooves, and the length difference between the small ejectors is very small, generally 0.1mm. According to the actual needs, different numbers and lengths of small ejectors are embedded in different areas

3，Two kinds of common blank holders

（1）Elastic blank holder is composed of spring cushion, rubber cushion and air cushion of press, which is used for processing shallow drawing parts

（2）Rigid blank holder is suitable for drawing or forming large parts with large height
