Description
Technical Field
The invention relates to upsetting equipment, in particular to upsetting equipment for forming a crankshaft or a flange by upsetting at one time.
Background
The upsetting device is a one-time extrusion forming device for producing crankshafts or flanges, extruded blank materials are placed between an upper die base and a lower die base of the upsetting device to complete an extrusion forming task, the lower die base is in a semi-cylindrical cavity shape and consists of a left side lower die base and a right side lower die base which are respectively arranged on horizontal guide rails in the left and right directions on a hydraulic press workbench, the upper die base is also in a semi-cylindrical cavity shape and consists of a left upper die base and a right upper die base, the upper die base is in an omega shape, wing plates at the two bottom ends of the omega-shaped upper die base are respectively provided with a toggle rod lower end extrusion groove, the upper die base is connected with a toggle rod, the lower end of the toggle rod is hinged in the toggle rod lower end extrusion groove, the upper end of the toggle rod is hinged on the toggle rod base, the toggle rod base is fixedly arranged on a C-shaped beam of the upsetting device, the upper die base is hinged at the lower end of the, when a C-shaped beam of the upsetting device is pressed downwards, an upper die base also descends along with the C-shaped beam, after the upper die base falls onto a lower die base, the upper die base and the lower die base are matched, after the upper die base and the lower die base are matched, the C-shaped beam presses the upper ends of four toggle rods through the toggle rod bases, under the pushing of the four toggle rods, a left die base and a right die base move oppositely to extrude a blank in the die bases, and because the upper die base is heavy, in the process that the upper die base descends along with the C-shaped beam, the lower bottom surface of the upper die base is required to be always kept in a horizontal state to fit the matching surfaces of the upper die base and the lower die base when the upper die base and the lower die base are matched, in order to achieve: the front end and the rear end of the inner side of the upper die holder on the left side are respectively provided with a hanging point of a balance chain, the outer sides of the two C-shaped beams are respectively provided with a balance chain pulling oil cylinder, the front end and the rear end of the inner side of each C-shaped beam are respectively provided with a reversing fixed pulley, a piston rod of the balance chain pulling oil cylinder is connected with one end of the balance chain, the other end of the balance chain is connected with the hanging point of the balance chain arranged at the inner side end of the upper die holder after being turned by the reversing fixed pulley, and the bottom end face of the upper die holder is always kept in a horizontal state in the pressing process of the C-shaped beams by adjusting the stroke of the four balance; because the upper die base on each side achieves the purpose of keeping the bottom surface of the upper die base horizontal through the two balance chains to pull the oil cylinders and the respective balance chains, the coordination consistency of the two balance chains to pull the oil cylinders is poor, the regulation deviation is easy to occur, the stable combination of the upper die base and the lower die base is influenced during die assembly, and particularly the upper die base is easy to shake in the descending process of the C-shaped beam due to the L-shaped balance chains; when the stroke position of the oil cylinder pulled by the balance chain has an error, the upper die base cannot be in collision with the limiting screw rod in the falling process, so that the upper die base cannot return to the original position, and the fit surfaces of the upper die base and the lower die base are not fit when the upper die base and the lower die base are closed; in addition, when the upper die base and the lower die base are separated, the upper die base is subjected to large impact force and is easy to swing, and the swing force easily causes the breakage of the balance chain, so that the equipment is damaged.
