Problems solved by technology

[0002] The traditional process of stretching the T15 outer wheel cover is generally manual stretching, trimming, shaping, punching, etc., but with the improvement of the requirements of the automobile factory for parts, the traditional forming process can no longer meet the production, which will mainly cause the product The scrap rate is very high, and even lead to the failure of parts development, the labor intensity of workers is high, the production efficiency is low, and it will also cause a lot of waste of materials
[0003] The Chinese patent application number is 201410379392.7, which discloses a method for making PP / PET blended environmental protection, waterproof and oil-proof automobile outer wheel covers. The product is heated and molded by a shaping machine, wherein the temperature is 200-220 ° C, and the holding time is 90-100 seconds. , and finally through the front embossing process of the product by the embossing machine to obtain the required outer wheel cover of the car. This method only passes one stretch, which will result in many unqualified products and high product scrap rate

Abstract

The invention discloses a low-rejection-rate T15 outer wheel casing three-time stretching forming process and relates to the technical field of automobiles. The low-rejection-rate T15 outer wheel casing three-time stretching forming process comprises the steps of fabric heating, the first time of stretching, the second time of stretching, the third time of stretching, trimming and shaping process.A three-time stretching forming mode is adopted, through the successive multi-section stretching process, necking-down and cracking phenomena in the stretching process are reduced, the rejection rateis lowered, meanwhile, workload of workers is reduced, materials are also saved, and product efficiency is also improved.
