Problems solved by technology

There is no X-ray inspection in the manufacturing process of this invention, and the pre-machining is canceled, which respectively cause safety hazards in the subsequent wheel hubs of the die-casting process and the spinning process
Although the improvement of the casting machine and the mold improves the quality of the cast product, it cannot guarantee that the product 100% meets the customer's standard, and the customer requires that the product must be 100% fully inspected by X-ray. At the same time, the process does not have a short process layout. To describe, the die-casting process takes a long time, while the spinning process takes a short time, so there must be a reasonable match to realize automated in-line production

example 1

[0014] Example 1: A manufacturing process of an aluminum alloy wheel, the process flow is: casting--deburring--soaking--spinning--heat treatment--de-gate-- --X-ray----machining.

[0015] The casting process is to develop a fully water-cooled mold, that is, to cool the casting mold by water cooling, the holding pressure is 830mbar, the holding time is 120s, the cooling time after pressure relief is 35s, and the production cycle is increased from the original 6min / piece to 4min / piece, casting production efficiency increased by 33%; the application of fully water-cooled molds will improve the quality of the wheel, the elongation rate of the spoke and wheel center will increase to 6%, and the elongation rate of the inner rim and rim will increase to 10%, which can reduce the wheel load. Weighs 0.7Kg. The water-cooled mold abandons the form of air cooling, which saves the cost of compressed air.

example 2

[0020] Example 2: The casting process is to develop a full water-cooled mold, that is, to use water cooling to cool the casting mold, the holding pressure is 850mbar, the holding time is 150s, the cooling time after pressure relief is 50s, and the production cycle is changed from the original 6.5min / 4.2 min per piece, casting production efficiency increased by 35%; the application of full water-cooled molds will improve the quality of the wheel, the elongation rate of the spoke and wheel center will increase to 8%, and the elongation rate of the inner rim and rim will increase to 10% , can reduce the weight of the wheel by 1.1Kg. The water-cooled mold abandons the form of air cooling, which saves the cost of compressed air.

[0021] The de-flashing process refers to the use of special de-flashing equipment to remove the flash of the casting blank at the rim, so as to ensure that no flash is screwed into the rim after spinning, prevent defects such as folding, and ensure the q...

Abstract

The invention discloses a manufacturing process of an aluminum alloy wheel. The process flow is: casting-deburring-soaking-spinning-heat treatment-degating-X-ray-machining. The present invention improves casting production efficiency and product quality, saves original cooling compressed air, cancels pre-machining, blank preheating spinning with temperature, blank with warm heat treatment, etc., saving costs of about 18 yuan / piece, and the weight loss of finished products is 0.7-1.1 Kg, the comprehensive manufacturing cost is the same as that of ordinary cast wheels, which improves the market competitiveness of cast spin wheels. It realizes the short process, light weight and low-cost technology of spinning wheel processing and manufacturing, and realizes the intelligent processing, which is suitable for the automatic production of large-scale spinning wheels.

Description

technical field [0001] The invention relates to the field of wheel manufacturing, in particular to a manufacturing process of a cast-spin aluminum alloy wheel. Background technique [0002] The spin-cast aluminum alloy wheel is a kind of aluminum alloy wheel whose spokes are formed by low-pressure casting technology and the rim is formed by powerful spinning technology. The process flow is: casting - cooling - X-ray - de-gate - milling platform - pre-machining - preheating - spinning - --cooling----heat treatment----machining, at present, this process has resulted in the ineffective use of blank temperature, low utilization rate of metal materials, high manufacturing cost, and inconsistent casting and spinning beats, which cannot be realized Automated in-line production. [0003] The application publication number published by the State Intellectual Property Office: CN 104128743 A "Low-pressure casting and spinning short process technology of aluminum alloy wheel hub" impr...
