Description

Fastener demoulding mechanism for vehicle

Technical Field

The utility model belongs to the technical field of the stamping equipment technique and specifically relates to an automobile-used fastener demoulding mechanism is related to.

Background

The stamping is a forming method in which a press and a die are used to apply external force to a plate, a strip, a pipe, a profile, etc. to cause plastic deformation or separation, thereby obtaining a workpiece (stamped part) of a desired shape and size. Stamping and forging are plastic working (or called pressure working), and are called forging and pressing. The stamped blanks are mainly hot and cold rolled steel sheets and strips. In the world, 60-70% of steel materials are plates, and most of the plates are punched to form finished products. The automobile body, chassis, oil tank, radiator fin, etc. are all processed by punching;

the stamping process is a production technology for obtaining product parts with certain shape, size and performance by directly applying deformation force to a plate in a die by means of the power of conventional or special stamping equipment and deforming the plate. The plate, the die and the equipment are three elements of stamping processing. The hot stamping and the cold stamping are divided according to the stamping processing temperature. The former is suitable for processing sheet materials with high deformation resistance and poor plasticity; the latter is carried out at room temperature and is a common stamping method for thin sheets. It is one of the main methods of metal plastic working (or pressure working), and also belongs to the material forming engineering technology.
