An adjusting mechanism of a closed upper dead center of a fine stamping machine is used for adjusting the closed upper dead center of the fine stamping hydraulic press. A main oil cylinder sleeve is matched with an adjusting nut; the adjusting nut and a large gear risk are connected into a whole; a first support and a second support are fixed on the main oil cylinder sleeve; a hydraulic clutch is fixed on the first support; the large gear disk is meshed with a first cylindrical gear and a second cylindrical gear which is driven by a gear motor to rotate; an axial clearance elimination plunger is arranged on the main oil cylinder sleeve; a plunger cylinder of the axial clearance elimination plunger is communicated with high pressure oil; a main piston and a guide seat and a lower workbench are connected into a whole; an encoder gear shaft is connected with an encoder and meshed with the second cylindrical gear; high pressure oil is communicated between the main oil cylinder sleeve and the main piston. According to the adjusting mechanism of the closed upper dead center of the fine stamping machine, the motor adjustment is matched with a hydraulic system and accordingly the adjusting speed is high, the adjusting accuracy and the repeated positioning accuracy are high, the die and equipment safety coefficient is greatly improved, the service life of fine stamping dies can be effectively extended, and the die production cost and the die adjustment time can be reduced.
Description
technical field [0001] The invention relates to the technical field of automatic control of mechanical equipment, in particular to an adjustment mechanism for an upper closing dead point of a precision blanking hydraulic press. Background technique [0002] The precision blanking hydraulic press (hereinafter referred to as the fine blanking machine) is developed on the basis of the ordinary stamping machine. The fine blanking is the powerful edge punching. The process principle is to use a special structure fine blanking die on the three-action press , Under the action of strong force, make the material produce plasticity and shear deformation, so as to obtain high-quality fine blanking parts. The fine blanking machine must be able to provide blanking force, blank holder force and back pressure at the same time. The main machine should have high strength and high rigidity. The slider can ensure precise guidance, and can accurately adjust the height of the closed dead point o...
