Hinge beam integral die-forging and forming combined die and hinge beam machining method thereof

Abstract

The invention relates to a hinge beam integral die-forging and forming combined die. The hinge beam integral die-forging and forming combined die comprises a concave die and convex dies; the concave die consists of an outer hoop plate assembly, four concave die sections and a center punch which are fixed together by a screw; the outer hoop plate assembly comprises multiple layers of outer hoop plate rings and an outer hoop bottom plate; the center punch consists of a cylindrical punch bottom plate at the bottom and a frustoconical punch projection on the upper part, and the punch projection and the punch bottom plate are coaxial; and each concave die section consists of a convex section of which the top surface is fan-shaped, an arc-shaped vertical plate of which a side surface is L-shapedand a die section bottom plate with a 1 / 4 periphery, and a connecting ridge is arranged at a position where each die section bottom plate is connected with the corresponding arc-shaped vertical plate. The two convex dies which are perfectly matched with the concave die are used in machining. A using method of the combined die is provided. By a process mode of optimizing a die cavity and the like,the problem that the position of a lug of an existing forging and pressing die cannot be full is solved, and the method with small residual machining allowance is implemented.

Description

technical field [0001] The invention relates to a hinged beam integral forging combined die, in particular to processing equipment and a processing method for a hinged beam, and belongs to the technical field of forging processing. Background technique [0002] The main equipment used in the field of superhard material synthesis is the six-sided top press. The hinged beam is one of the core parts of the six-sided top press, and its quality directly affects the quality of superhard materials. The original hinge beam is produced by casting process. Due to the complex shape of the hinge beam, it is difficult to control the casting defects. During the use process, accidents such as the bottom of the cylinder body and the breakage of the ear hole are prone to occur. In the existing design scheme, in order to meet the performance requirements , In the design process, it is often necessary to increase the casting wall thickness, which not only wastes raw materials, but also simply...
