Abstract

A hot extrusion forming mold and forming method for a special-shaped deep-cavity complex-structure support are disclosed. The mold includes an upper mold, a lower mold, guide columns and guide sleeves. The lower surface of the upper mold and the upper surface of the lower mold are horizontal surfaces. The lower surface of the upper mold is provided with a punch, and the upper surface of the lowermold is provided with a matrix corresponding to the punch, with the matrix having an inward concave structure and the periphery of the matrix being provided with a flash cavity. The four sides of theflash cavity are provided with guide slots. A gap is left between the punch and the matrix after assembling to form the shape of a support forge piece. Two angle positions of a diagonal line of the upper mold and the lower mold are provided with guide column holes correspondingly, with one guide sleeve being disposed in each guide column hole. The guide sleeves and the corresponding guide column holes are fastened in a press fit manner. The upper mold and the lower mold are positioned through inserting the guide columns into the corresponding guide sleeves of the upper mold and the lower moldrespectively. Through the design of the punch, the matrix, the flash cavity and the guide slots, blank material flowing is controlled so as to control the dimension precision of the support forge piece, and an excessive blank material can be discharged.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to a special-shaped deep cavity complex structure bracket hot extrusion forming die. Background technique [0002] The general trend of national defense security requires that the response speed of weapons and equipment replacement is getting faster and faster, and the technical and tactical indicators are getting higher and higher. Weapons and equipment gradually show the characteristics of lightweight, complex and integrated structures, and the requirements for the ratio of components to weight and strength continue to increase. , the contradiction between structural lightweight and high-strength requirements is becoming more and more prominent. In order to meet the above requirements, a large number of light alloy special-shaped complex thin-walled structures are used in aerospace weapon components. Among them, the cross-section of a certain type of aeros...
