Abstract: There are 5 sets of 800～1 200 t stamping hydraulic presses in the F line production line of the stamping workshop of Shandong Wuzheng Group Co., Ltd., and the problems of high energy consumption, frequent failure and energy waste are found in the actual production process. In order to reduce energy consumption, reduce the failure rate of equipment, and improve the service life of equipment, we independently designed and manufactured the regulating valve block to realize the automatic return stroke of the buffer cylinder, improved the control program to realize the automatic selection of the oil pump, and developed a temperature control linkage system to prevent the equipment from overheating. The improvement results show that the failure rate of stamping equipment is effectively reduced, the overall energy consumption of the workshop is significantly reduced, and the cost is saved by 300,000 yuan within one year after the transformation, which effectively improves the operating energy efficiency of the stamping production line. At the same time, summarize relevant experience and promote it to provide reference for other equipment energy-saving improvement.
