[CN 201620642443.5] Size compensation device for large hydraulic press


[CN 201620642443.5] Title of a large hydraulic machine size compensation device: Application number of a large hydraulic machine size compensation device: CN 201620642443.5 Applicant: China Heavy Machinery Research Institute Co., Ltd. Application Date: 2016-6-24 Patent Type: Utility Model A large hydraulic machine size compensation device includes a displacement sensor fixed on the lower beam through a fixed bracket, and the slider on the displacement sensor is connected with the lower end of the fixed rod through a pin shaft, the upper end of the fixed rod is fixedly connected to the upper beam through the upper fixed block, and the upper fixed block and the fixed rod are fastened by locknuts; the signal output of the displacement sensor is connected to the input of the electrical control system, and the output of the electrical control system is connected to the input of the hydraulic control system. The forging of the forging is controlled by the hydraulic control system, and the direct displacement change of the upper beam and the lower beam is measured by the displacement sensor, the displacement sensor transmits the real-time deformation of the frame to the electrical control system for real-time forging size revision, and controls the hydraulic system to complete the forging of the forgings, so as to realize the actual forging size and set size within the actual control accuracy, improve the dimensional accuracy of the forgings, reduce the overall forging time, and improve the production efficiency.
