hydraulic punch pressIt is a processing equipment for rapid shallow stretch molding. It can be made into cylindrical, rectangular, stepped, semicircular, conical and other irregular shaped thin-walled parts by stretching process. It has the advantages of rapid prototyping, stable and reliable work, high precision and high efficiency.

Stretch forming hydraulic punch is mainly suitable for sheet metal calendering, stamping, forming and shallow drawing process of plastic materials. Such as watchcase, table bottom cover, watchband, all kinds of gold and silver jewelry, badges, commemorative coins, glasses, lighting shell suppression, etc;

How does the hydraulic punch complete shallow stretch forming?

The stretching pad is an indispensable device for hydraulic punching machines to complete shallow stretching forming. In addition to pressing materials during stretching of punching machines, it can also be used for local forming of materials or the bottom of stamping finished products, which can improve the processing and application range of biaxial precision punching machines.

Hydraulic punching machine is generally the use of hydraulic stretching pad, installed in the punch table base to use, its specific working principle is as follows:

 

The stretching pad working cylinder communicates with the oil cylinder through a check valve and an overflow valve and a pipeline. In addition to the hydraulic oil, the oil and gas cylinder is also filled with compressed air. The pressure can be adjusted through a pressure regulating valve. The oil in the cylinder is pressed into the working cylinder through the pipeline check valve under the action of the upper compressed air, and the working cylinder And the support plate until it reaches the limit position.

 

When stretching work, the main oil cylinder drives the slider of the punch press to press down until the upper die contacts the material frame, and the oil pressure in the working cylinder of the oil pressure stretching pad starts to increase with the upper die pressing down. When the pressure rises to reach the rated pressure, the oil in the working cylinder of the oil pressure stretching pad will open the overflow valve. At this time, the oil will flow back to the oil and gas cylinder of the stretching pad through the pipeline, so that the support plate of the stretching pad will always maintain the rated pressure, and follow the slider to the bottom dead center to complete the stretching operation.
