Description

Technical Field

[0001] The invention relates to the technical field of hardware accessories processing, in particular to a punching machine for processing hardware accessories with an automatic ejection function. Background Art

[0002] Metal stamping is a process that uses a punch press and a mold to deform or break stainless steel, iron, aluminum, copper and other plates and special materials to achieve a certain shape and size. Metal stamping is sometimes also called sheet forming, but there is a slight difference. The so-called sheet forming refers to the use of sheets, thin-walled tubes, thin profiles, etc. as raw materials. The forming method of plastic processing is collectively called sheet forming. At this time, the deformation in the direction of the thick plate is generally not considered. Metal stamping needs to be completed using a punch press.
