Description

Technical Field

[0001] The utility model relates to the field of stamping equipment, in particular to a stamping device for manufacturing hardware accessories. Background Art

[0002] Stamping is a forming method that uses a press and a die to apply external force to plates, strips, tubes and profiles to cause them to undergo plastic deformation or separation, thereby obtaining a workpiece of the desired shape and size. Stamping is a production technology that uses the power of conventional or special stamping equipment to directly subject the sheet material to a deformation force in the die and deform it, thereby obtaining product parts of a certain shape, size and performance.

[0003] When stamping and producing hardware accessories, metal sheets need to be placed on a mold and stamped and formed by a stamping machine. When stamping sheets of different sizes, the existing stamping devices are inconvenient to fix the sheets, and cannot achieve rapid fixation and disassembly of the sheets. When continuously stamping the sheets, the sheets are usually moved by the user, which poses certain safety hazards and is not conducive to the normal production and use of hardware accessories.
