TECHNICAL FIELD

[0001] The utility model relates to the field of punch mould technology, in particular to an automatic feeding mechanism of automobile accessory punch mould. BACKGROUND

[0002] The punch mould is a kind of special process equipment for processing material (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, and is called cold stamping die (commonly known as cold punch mould). Punching is a kind of pressure processing method that separates or plastically deforms materials at room temperature by using the mould installed on the press to apply pressure to the materials.

[0003] At present, the raw material (usually long strip raw material plate) needs to be flattened and then transmitted to the press for stamping when the automobile accessory is punched, so workers need to constantly flatten and place the raw material plate at the front end of the press, which makes the working strength of the workers higher, and the strength requirement of the workers is also higher, which is not conducive to the efficient production of automobile accessories and needs to be improved.
