Embodiment Construction
[0014] The present invention is described in detail below in conjunction with accompanying drawing:
[0015] A self-holding type upsetting equipment with an upper die base in a horizontal state, comprising a lower anvil 1, on which a lower die base guide rail 2 is arranged, and a left lower die base 3 and a right lower die base 27 are respectively arranged on the lower die base guide rail 2 An upper anvil 4 is arranged directly above the lower anvil 1, and the upper anvil 4 is fixedly connected with the pressing mechanism of the press, and the rear C-shaped beam 5 and the front C-shaped beam are suspended on the upper anvil 4 respectively. 6. The rear C-shaped beam 5 and the front C-shaped beam 6 are arranged along the left and right horizontal directions, and are arranged in parallel with each other at intervals. Between the rear C-shaped beam 5 and the front C-shaped beam 6, a left upper mold base 7 and a right upper mold base are movable , the left upper die base 7 and the ...

The invention discloses an upper die base horizontal state self-maintaining upsetting equipment, and solves the problem that a mechanism used for ensuring the fitting of the joining surfaces of an upper die base and a lower die base during die closing in the existing upsetting equipment is complicated and easy to be damaged. The traditional balance chain pulling oil cylinder and the balance chainof the upper die base are removed, a front C-shaped beam (6), a left front push rod (19), a left upper die base (7) and a left front toggle rod (13) form a front parallelogram ABCD four-link mechanism, and a rear C-shaped beam (5), a left rear push rod, the left upper die base (7) and a left rear toggle rod (9) form a rear parallelogram four-link mechanism. When the left upper die base (7) falls around an upper pin shaft of a left front toggle rod seat (17) and an upper pin shaft of a left rear toggle rod seat, the two four-link mechanisms can keep the lower bottom surface of the left upper die base (7) in a horizontal state always. The upper die base horizontal state self-maintaining structure is self-realized and self-adjusted automatically by the self weight of the left upper die base,and the structure is simple.
Description
technical field [0001] The invention relates to an upsetting equipment, in particular to an upsetting equipment for forming crankshafts or flanges by one-time upsetting. Background technique [0002] Upsetting equipment is a one-time extrusion molding equipment for producing crankshafts or flanges. The extruded blank is placed between the upper mold base and the lower mold base of the upsetting equipment to complete the extrusion molding task. The lower mold The base is in the shape of a semi-cylindrical cavity, consisting of a lower mold base on the left and a lower mold base on the right. The left upper die base and the right upper die base are composed of the upper die base. Toggle bar, the lower end of the toggle bar is hinged in the extrusion groove at the lower end of the toggle bar, the upper end of the toggle bar is hinged on the toggle seat, the toggle seat is fixed on the C-shaped beam of the upsetting equipment, and the upper die seat is passed through the toggle...
