Problems solved by technology

Its shortcomings are: the temperature of the working parts such as the punch, the die, and the blank holder is the same, which is essentially an isothermal drawing mold, and lacks a device for controlling the mold temperature, so the mold temperature cannot be accurately controlled

Abstract

The present invention belongs to the field of mold technology, and is especially differential temperature magnesium alloy plate drawing mold. The magnesium alloy plate drawing mold includes upper mold plate, upper mold base plate, female mold, male mold, male mold fixing plate, lower mold base plate, lower mold plate, top plate, hold down plate and mandrel. The present invention may realize precise temperature control of the female mold, the hold down plate and the male mold separately, can apply blank holder pressure to the hold down plate, and possesses unloading function. The present invention can realize differential temperature drawing to raise the hot drawability of magnesium alloy plate.

Description

technical field [0001] The invention relates to a die, in particular to a differential temperature drawing die for a magnesium alloy plate, which belongs to the technical field of dies in mechanical engineering. Background technique [0002] As the lightest metal structure material in engineering applications (mass density of magnesium is about 2 / 3 of aluminum, 1 / 4 of steel), magnesium alloy has high specific strength, good rigidity, good damping coefficient, anti-electromagnetic interference and shielding With the advantages of good performance and high recycling rate, it has great application potential in auto parts, aviation, aerospace, electronics and other industries, and is known as the "green engineering material" with the most potential for development and application. Due to the hexagonal close-packed (hcp) crystal structure of magnesium alloys, the plasticity at room temperature is low, and the plastic processing ability is poor, so magnesium alloy parts are mainly...
