The Study Of Engine Brazing Pipes In Manufacturing Technique And Quality Control

There is a large market potential in China which is the Asia largest automobile market.The foreign automobile companies are define China as their leading market that the consumer preference make up their mind.Take oil wear and speed performance into account,the market analysis reported that turbocharge was going to the mainstream of the market in 2017.In order to making Toyota more competitive still,we expect that the corolla will configure turbocharged engine of 1.2T October,2017.With the introduction of new models,the key to win the market is the game of technology,quality and cost.The turbocharged engine have more pipes than the naturally aspirated engine,It includes metal pipes and rubber hoses.The rubber hoses had comprehensive localization in production models,but the metal pipes of high precision by importing or Japanese supplier that it's high price for a long time.So,we will be on the localization of metal brazing pipes that how to the parts of inexpensive and excellent quality is our task.Based on the above factors,we choose the brazing pipe suppliers in China and then we do technical assessment to them.The selected supplier had delivery performance of vehicle brazing pipes,but they don't have mature production experience of high-precision engine brazing pipes.They lack technical support especially in the aspects of brazing deformation and chronic leakage.For this,our task is how to guarantee the quality of brazing pipes through reasonable project setting.Next,we advance the works are how to guarantee the local parts conform to Toyota Standard and excellent production of large quantities,and how to make the product performance and applicability on the premise of low cost,and how to properly combine with the actual production of the product design and manufacturing process control.The author clearly the point of difference on the production equipment and production methods by combining foreign advanced manufacturing experience in the field of brazing pipes.I summarized production mode of the domestic brazing pipe that accord with the practice during the development phase of 1.2T.It discuss the production process and quality control points of brazing pipes from the aspects of selecting and using of brazing filler metal,assembling of components,setting and testing of the bracket,brazing parameters settings,making surface treatment,inspecting.This paper discuss the effective countermeasures in the process of production engine brazing pipes,and analysis the common failure modes by actual examples.In order to make our products meet the design indexes and complete vector production phase of smooth transition that we continuously review and improve.On the premise of low cost,we must complete the vehicles' income index that guarantee the stability of product quality and shorten the ordering cycle and realize parts localization.
