Abstract

The invention relates to a die for controlling forming of an asymmetric complex-curved rebar forge piece by using a movable damping block, in particular to a forming die of an asymmetric complex-curved rebar forge piece, which solves the problem that the junction of the curved surface of an asymmetric complex-curved bar component is easily folded and not fully filled in the existing forming process. A male die (13) is provided with two pressure relief discharge openings (14), and the setting position of each pressure relief discharge opening (14) is positioned right above the corresponding side-ear connecting rib (17-1) of the asymmetric complex-curved rebar forge piece (17); the male die (13) is provided with a minor segment stepped hole (16); a movable damping block (24) is arranged in the lower end hole (16-2) of the minor segment stepped hole (16); a male die heating plate (10) is provided with a through hole (10-1) of a small punch (12) of a hydraulic press; and the through hole (10-1) of the small punch (12) of the hydraulic press corresponds to the minor segment stepped hole (16). The die is applicable to forming the asymmetric complex-curved rebar forge piece.

Description

technical field [0001] The invention relates to a mold for forming an asymmetric complex curved gluten forging, in particular to a mold for controlling the forming of an asymmetric complex curved gluten forging by using a movable damping block, and belongs to the technical field of forging forming technology. Background technique [0002] High strength, toughness and light weight are one of the important development trends of aerospace parts, especially the key stress-bearing parts, which not only require the parts to have good shape and dimension accuracy, but also require their internal microstructure to be good, with uniform and fine grain size, streamlined Distribution along the geometric contour of the part, etc. For aerospace parts with thin walls and complex ribs, the traditional mechanical processing method has low material utilization rate, long processing time, low production efficiency, and it is not easy to meet the mechanical performance requirements of the part...
