[CN 201811094995.7] Mechanical material jacking device for forging mechanical press
[CN 201811094995.7] Title of mechanical jacking device for forging mechanical press: Application number of mechanical jacking device for forging mechanical press: CN 201811094995.7 Applicant: Nanjing Institute of Mechanical and Electrical Technology Application Date: 2018-9-19 Patent Type: Invention Application for a mechanical jacking device for forging mechanical press, including a die holder, rectangular grooves on the bottom surface of the die holder, wedge grooves on both sides of the top surface of the rectangular groove, and vertical holes on the four corners of the top surface of the top surface of the die holder, the vertical holes are respectively communicated with the corresponding wedge-shaped grooves. Two parallel first screws are arranged in the rectangular groove. The two sides of the rectangular groove are fixedly connected with the two ends of the first screw at the same time. The outer circumference of each first screw is threaded. Four screw sleeves are installed, and the vertical holes are respectively provided with ejector rods, and the lower ends of the ejector rods are located in the corresponding wedge-shaped grooves. The invention drives the screw sleeve to move horizontally through the first screw, so that the ejector rod is vertically displaced, and the vertical movement of the ejector rod is quite stable, which can be applied to the forging of larger workpieces, and ensures that the ejection force of the mechanism will not be overloaded, Extend the service life of the press, improve the forging and extrusion quality and the manufacturability of the formed product, effectively use the heat energy of the hot forging workpiece, and reduce energy loss.
