A method for forming a square plate shell blank and its supporting forming die

Abstract

The invention provides a square plate shell blank forming method and matched forming dies thereof. The forming method comprises the steps of manufacturing saw cutting blank, conducting first sequence blocking extrusion on the saw cutting blank, conducting backward extrusion on square blind holes in the first sequence blank, forming an arc-shaped groove in the second sequence blank, and conducing solution and aging processing on the third sequence blank. According to the square plate shell blank forming method and the matched forming dies thereof, three times of extrusion forming are used, and the defects that the hardening strength is large and the plasticity is low in the blank processing process existing in one-time extrusion forming are overcome; the dies which are matched with the three working procedures for use are all blocking dies, in the blocking double-acting forming process, the upper die and the lower die are closed to form a formed cavity, the positions, the number and the movement sequence of convex die central spindles can be arranged according to the characteristics of the cavity and the flow regularity of the materials, and the plastic flow of the materials can be better controlled.

Description

technical field [0001] The invention relates to the technological application in the field of manufacturing aviation connectors, in particular to a method for forming a square shell blank and a matching forming mold thereof. Background technique [0002] In military aviation equipment and various electronic systems, the square plate connector is an indispensable basic component for connecting devices and components, components and stand-alone, stand-alone and stand-alone, systems and systems, and is used in military weapons such as aviation, aerospace, weapons and ships In equipment, it plays an important role in the electrical connection to transmit energy and signals. The material of the square plate connector is generally magnesium aluminum alloy, stainless steel, etc., and the dimensional accuracy requirements are relatively strict, and it must be adapted to various complex and harsh working environment conditions. The inner hole of the shell is a square blind hole with...
