[CN 201820894392.4] A New Kind of Packing Device for Forging Press
[CN 201820894392.4] Title of a new type of material lowering and jacking device for forging press: Application number of a new type of material lowering and jacking device for forging press: CN 201820894392.4 Applicant: Application date of Shandong Jinchen Machinery Co., Ltd.: 2018-6-8 Patent type: Utility model A new type of material lowering and jacking device for forging press, including a support frame, in which a power cylinder is vertically arranged upside down, and the piston rod of the power cylinder extends downward and is fixedly connected with the support frame, the cylinder body of the power cylinder is connected with a vertically arranged ejector rod passing upward through the support frame. The utility model adopts the above structure, which is reasonable in design, simple in structure, easy to manufacture, effectively reduces the difficulty of assembly and maintenance, and improves assembly accuracy; through the downward installation of the hydraulic cylinder or cylinder piston rod, it can prevent the oxide scale generated during the forging process from cooling The liquid will enter the piston rod sealing device or the piston rod will be corroded and cause pitting corrosion, which will then cause the hydraulic cylinder or cylinder sealing device to fail, effectively eliminating the hidden trouble of the hydraulic cylinder, improve the service life of the lower and upper material mechanism.
