[CN 201620864533.9] Sheet Precision Blanking Hydraulic Press Title: Sheet Precision Blanking Hydraulic Press Application Number: CN 201620864533.9 Applicant: Vode Precision Press (China) Co., Ltd. Application Date: 2016-8-11 Patent Type: Utility Model The utility model discloses a sheet precision blanking hydraulic press, which includes a main body, a main oil cylinder, a back pressure cylinder, a ring gear cylinder and a slider. The ring gear cylinder is arranged in the ring gear ring of the lower piston rod of the lower worktable of the fuselage, and the upper end of the cylinder, the lower guide sleeve is fixed in the center hole of the table plate. The main cylinder passes through the upper beam vertically downward and is fixed at the center of the upper beam, and the piston rod head of the main cylinder is fixed on the upper side of the slider. The back pressure cylinder is located in the sliding block, the lower side of the cylinder barrel of the back pressure cylinder is fixed inside the lower part of the sliding block, the lower end of the piston rod of the back pressure cylinder is supported in the upper guide sleeve, and the upper guide sleeve is fixed in the center hole on the lower side of the sliding block. The utility model has a simple structure, eliminates the defect of non-synchronization of the multi-cylinder system, greatly improves the rigidity of the body, ensures the operating accuracy of the slider, and meets the requirements of the use of high-precision fine-blanking dies. The forming rate of blanking parts is improved, the material waste cost is reduced, and the flatness, surface finish and dimensional accuracy of blanking parts are improved.
