Description

A stamping device for easy demoulding

technical field

The invention relates to the technical field of stamping machinery, in particular to a stamping device for easy demoulding.

Background technique

The principle of the stamping machine is to drive the flywheel through the motor, and through the clutch, the transmission gear drives the crank linkage mechanism to move the slider up and down, and drives the drawing die to form the steel plate. The so-called double action means that the press has two sliders, which are divided into an inner slider and an outer slider. The inner slider drives the punch or die of the mold, and the outer slider drives the blankholder on the mold. When the blank holder first moves to press the edge of the steel plate, the inner slider moves again to stretch.

Stamping relies on presses and molds to apply external forces to plates, strips, pipes, and profiles to cause plastic deformation or separation to obtain workpieces (stampings) of required shape and size.

Stamping processing is a production technology that uses the power of conventional or special stamping equipment to directly subject the sheet to deformation force and deform in the mold, so as to obtain product parts of a certain shape, size and performance. Sheet metal, mold and equipment are the three elements of stamping processing.

According to the stamping processing temperature, it is divided into hot stamping and cold stamping. The former is suitable for sheet metal processing with high deformation resistance and poor plasticity; the latter is carried out at room temperature and is a commonly used stamping method for thin plates. It is one of the main methods of metal plastic processing (or pressure processing), and it also belongs to material forming engineering technology.

The stamping machine is a kind of mechanical equipment that drives the flywheel through the motor, and drives the crank linkage mechanism through the clutch and the transmission gear to move the slider up and down, and drives the drawing die to form the stamping parts.

At present, when stamping stamped parts, the stamped workpiece is often stuck on the abrasive tool, and it needs to be lifted manually. Sometimes it takes a lot of manpower and material resources to solve it because the jam is too tight. Time-consuming and labor-intensive, and easily lead to safety accidents.
