Example Embodiment

[0014] The specific embodiments will be described in detail below in conjunction with the accompanying drawings (this embodiment is a further description of the present invention, rather than any limitation of the present invention).

[0015] combined with figure 1 and 2 The detailed implementation rules are explained, taking a magnesium wheel with a size of 18X8.5 inches and a material of AZ80 as an example, the process of using the forging process of the present invention to produce a magnesium alloy wheel is as follows:

[0016] (1) Saw and cut the blank magnesium alloy round bar, the blank size is Φ229X200mm (9-inch bar), as an option, the heating temperature of the blank is set to 385°C, and the preheating temperature of the initial extrusion and final extrusion die is the same as the blank. same;

[0017] (2) Put the heated bar into the preliminary extrusion die for preliminary extrusion. The preliminary extrusion process preliminarily forms the spokes and rim part...

Abstract

The invention discloses a magnesium alloy wheel forging forming method. The technological process of the magnesium alloy wheel forging forming method can be summarized as ''twice-squeezing and once-rotating''. The magnesium alloy wheel forging forming method is characterized by comprising the steps that (1), heating is conducted, wherein a round magnesium alloy blank is heated to the forging temperature, and the temperature of a die is controlled to be equal to that of the blank; (2), primary squeezing is conducted, wherein primary forming of spokes and a rim is completed in a closed backward squeezing way, but an outer rim is not formed; (3), final squeezing is conducted, wherein the outer rim is finally formed in a closed forward squeezing way, and backward-squeezing final forming of the rim portion are completed at the same time; and (4), inward rotary squeezing for forming is conducted, wherein flaring of the rim and forming of a folded edge of an inner rim are completed through inward rotary squeezing. The magnesium alloy wheel forging forming method has the advantages that the technological process is simple; the streamline is smooth; the production efficiency is high; the utilization rate of materials is high; the defect of cracking can be effectively avoided in the forming process; and the volume production can be achieved easily.

Description

technical field [0001] The invention belongs to the technical field of light alloy forming and is applied to the wheel manufacturing industry. technical background [0002] Among practical engineering materials at present, magnesium alloy is the material with the smallest specific gravity, only 1 / 4 of steel and 2 / 3 of aluminum. The specific strength and specific stiffness of magnesium alloy are higher than those of steel and aluminum alloy materials. In addition, magnesium alloy also has Excellent shock resistance, impact resistance and wear resistance, as well as good cutting performance, so magnesium alloy materials are more and more widely used in industry. The reserves and output of magnesium in my country rank first in the world, and the development of deep processing technology for magnesium alloys has great economic value. [0003] In order to meet the development needs of automobile energy saving and emission reduction, the lightweight of automobiles has become an i...
