Abstract

The invention relates to a magnesium alloy precision forging die and a magnesium alloy precision forging process. The magnesium alloy precision forging die comprises a punch, a preheating device, an ejector, a female die, a die holder, a push rod and a worktable, the punch is mounted on a slider of a servo press, the preheating device is mounted in the die holder, the die holder is fixed onto the worktable of the servo press, the female die is fixed onto the die holder, the push rod is arranged between the female die and the die holder, the ejector is arranged on the upper portion of the push rod, and a forming workpiece is arranged between the ejector and the punch. The process includes the steps of feeding, blank preheating, servo precision forging, die sinking and ejecting. The servo press is used for precision forging of a magnesium alloy LED radiator, and the displacement and the speed of the slider can be controlled during forging. Isothermal precision forging of the magnesium alloy LED radiator can be facilitated, so that the mechanical property of materials, product quality and production efficiency are improved, reference is provided for precision forging of magnesium alloys, and the forging process and the application range of the servo press can be expanded.

Description

technical field [0001] The invention relates to a magnesium alloy precision forging forming die and a forming process thereof, which belong to the modification technology of the magnesium alloy precision forging forming die and the forming process thereof. Background technique [0002] At present, LED heat sinks are mainly formed by aluminum alloy die-casting. Compared with precision forging, die-casting production has defects such as high energy consumption, serious pollution, prone to defects, and low performance. Therefore, the development of LED heat sink precision forging Forming technology is of great significance. [0003] Aluminum alloy is mostly used as the material of LED heat sink. Although the thermal conductivity of aluminum alloy is higher than that of magnesium alloy, from the perspective of the material itself, the factors affecting the heat dissipation performance of the heat sink are not only thermal conductivity, but also related to the specific heat of th...

Problems solved by technology

Forming magnesium alloys on ordinary crank presses is difficult to form due to the uncontrollable movement of the slider and the high speed; while forming on hydraulic presses is controllable, but the production efficiency is low, and high-temperature forming requires special treatment to prevent the hydraulic system from forming. affected by issues such as
