Description

Preheating system for hydraulic press

technical field

The utility model relates to the field of hydraulic presses, in particular to a preheating system for hydraulic presses.

Background technique

The hydraulic press is a kind of special hydraulic oil as the working medium and the hydraulic pump as the power source. The force of the pump makes the hydraulic oil enter the cylinder/piston through the hydraulic pipeline, and then there are several sets of seals that cooperate with each other in the cylinder/piston. , The seals in different positions are different, but they all play a role in sealing, so that the hydraulic oil cannot leak. Finally, through the one-way valve, the hydraulic oil is circulated in the oil tank to make the oil cylinder/piston circulate to do work, so as to complete certain mechanical actions as a kind of machinery of productivity. When the hydraulic press stamps certain workpieces such as plastic parts, aluminum parts with special requirements, and sheet metal parts, it is necessary to preheat the above-mentioned workpieces to improve the quality of the stamped products. However, during the operation of the traditional hydraulic press, Usually, the workpiece is heated by external heating equipment and then moved to the mold. However, after the workpiece is preheated, especially the plastic workpiece, it is easy to soften and deform. During the process of moving and placing, it is difficult to align, and even partially deformed and folded. Bending, reducing the efficiency and quality of stamping processing.
