Extrusion die for thin-walled light alloy component with near-contour shape

Abstract

The invention discloses an extrusion forming die for a thin-wall near-contoured chevron light alloy member, which comprises an upper die component, a lower die component, an ejection device, a material ramming device, a fixed component and a movable component, wherein the upper die assembly comprises an upper die plate, a male die fixed ring, a first pass male die and a second pass male die, the first pass male die and the second pass male die are interchangeable, the lower die assembly comprises a lower template, a female die, a middle female die and a mandrel, the middle female die and the mandrel are interchangeable. When the upper die assembly is assembled with the first pass male die, the female die is correspondingly provided with the middle female die, a middle male die is providedwith a discharging channel, and a lower annular wall is extended out of the lower section of the discharging channel. The ejection device comprises an ejection block and an ejector rod. The material ramming device comprises a material ramming plate. The fixed component and the movable component comprise an umbrella cap, a cylindrical pin, a fixed block, a hanging erbium and a chain. According to the extrusion forming die for the thin-wall near-contoured chevron light alloy member, the precise plastic forming of the thin-wall near-contoured complex chevron member is achieved, the problems brought by the traditional processing and manufacturing die are effectively overcome, the formability of the light alloy is improved, the comprehensive mechanical property of the formed member is improved, the material utilization rate is greatly improved, the energy is saved and the consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of plastic processing and forming of metal materials, in particular to an extrusion forming die for a light alloy component with a thin wall and nearly equal mountain shape. Background technique [0002] With the rapid development of my country's aerospace technology, high-tech weaponry and marine development, thin-walled near-alpine-shaped light alloy components (thin-walled near-alpine-shaped components refer to the overall component composed of two inner and outer ring walls, the inner ring wall and The wall of the outer ring is thin and the height is close to flush) is more and more widely used in various fields. For example, missiles and satellite cabins with double-walled shells, marine action transmission equipment with double-walled mountain-shaped components, tracked vehicles and other equipment are equipped with complex forgings with double-walled shapes, etc. There are many double-thin-walled near...
