A multi-directional forging die for large cylinder forgings

Abstract

The patent relates to a multi-directional forging mould for a large cylinder forging. The multi-directional forging mould for the large cylinder forging is characterized in that half mould cavities which are in longitudinal symmetry are separately arranged on the left sides and the right sides of an upper mould (1) and a lower mould (2); after the upper mould (1) and the lower mould (2) are closed, the mould cavities on the left sides of the upper mould (1) and the lower mould (2) form a cavity (6) which is matched with the body of the large cylinder forging; the mould cavities on the right sides of the upper mould (1) and the lower mould (2) form a second cavity (7); a waste billet of the large cylinder forging is placed in the mould cavity on the left side of the lower mould (2) and is subjected to primary forging by closing the upper mould (1) and the lower mould (2); then, a left punching head (3) enters the cavity (6) to perform upsetting forging; and simultaneously, a right punching head (4) also enters the second cavity (7) to achieve the effects of fixing the multi-directional forging mould and eliminating side stress of equipment until the forging and forming of the body of the large cylinder forging in the cavity (6) are completed. The mould is designed and manufactured according to the forging. In mould design, working pressure are applied to the upper mould, the lower mould and the left punching head synchronously; the left punching head achieves the effect of counteracting the side stress of the equipment; and the upsetting forming of a cylinder core is benefited.

Description

Technical field [0001] The invention belongs to forging technology and relates to a forging die for multidirectional forging of cylindrical forgings for aviation. Background technique [0002] The cylinder body of the aero-engine actuating cylinder is used as an adjustment accessory in the engine. At present, these forgings are generally used for isothermal forging to make solid forgings. The molding method of adding an inner hole on the machine has low material utilization, long forging cycle, low production efficiency and high cost. . Summary of the invention [0003] The purpose of the present invention is to directly forge cylindrical forgings by adopting the multi-directional forging method under the existing equipment conditions, with uniform deformation of the forgings, good structure and performance. [0004] Technical solution of the present invention [0005] A multi-directional forging die for large-scale cylindrical forgings, characterized in that: the multi-directional ...
