Abstract
The utility model discloses a high-speed cold forging hydraulic press, which comprises an oil filter and a variable displacement pump. The variable displacement pump is connected with the oil filter and an electromotor and is communicated to a port P of an electrohydraulic reversing valve, a joint A of the electrohydraulic reversing valve is communicated with a sequence valve, the sequence valve is connected to a fast chamber of an oil cylinder, and the fast chamber of the oil cylinder is further connected with another oil supply loop. The other oil supply loop includes that an oil filter, a variable displacement pump, an electromotor, a pilot operated check valve and a check valve which are communicated mutually, the variable displacement pump is connected with the pilot operated check valve, the pilot operated check valve is communicated with the check valve, and the check valve is communicated with the fast chamber of the oil cylinder. By the aid of the high-speed cold forging hydraulic press which is environment-friendly, pressure loss can be reduced and materials and labor can be saved. Further, surfaces of products pressed by the hydraulic press are high in density and smooth, service lives of the products are prolonged, and quality of the products is high.
