Forging and moulding die for composite insulator ball socket fitting

Abstract

The invention relates to a forging and moulding die for a composite insulator ball socket fitting. The forging and moulding die is characterized by comprising an upper die plate, a convex die, movable die holders, a fixed die holder, a lower die holder and a demoulding mandril, wherein the convex die is arranged on the upper die plate; a left die core and a right die core are respectively arranged on the left movable die holder and the right movable die holder, and the left die core and the right die core are assembled to form a cavity for accommodating the ball socket fitting; the fixed die holder is fixed on the lower die plate, an inner cavity is formed in the center of the fixed die holder, the left movable die holder and the right movable die holder are arranged in the inner cavity of the fixed die holder, and the left movable die holder and the right movable die holder are matched with the side wall of the inner cavity of the fixed die holder through a guide structure, wherein the upper end of the guide structure inclines outwards. In the compression process, a ball socket fitting blank is subjected to pre-forging and trimming and then put in the die cores, the convex die moves downwards, and a ball socket is subjected to once compression moulding in the die cores; in the demoulding process, a demoulding cylinder jacks upwards, the die cores move upwards along with the left movable die holder and the right movable die holder, so that the demoulding is realized; and the forging and moulding die is high in compression efficiency, and the manufactured ball socket fitting is low in rejection rate.

Description

technical field [0001] The invention relates to a forging molding die, in particular to a forging molding die for a composite insulator ball socket fitting. Background technique [0002] Composite insulator ball socket fittings such as figure 1 As shown, it has a ball socket b at the end a of the fitting. The current composite insulator ball socket fittings are manufactured by casting. The disadvantages are: the internal structure is loose, there are defects such as shrinkage cavities and cracks, and the quality is up to If the requirements are not met, there is a greater potential safety hazard and more scrapping. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a composite insulator ball-socket fitting forging molding die with low rejection rate and high processing efficiency. [0004] In order to solve the above technical problems, the technical solution of the present invention is: a forging mold for composi...
