F2000Cab Drawing Performance Of

The drawing process is a complex process of plastic deformation, It is influenced by many factors the larger deformation process。 Therefore, drawing die is prone to all kinds of difficult to analyze problems, and only in the problems to solve, cannot accomplish beforehand prevention。In recent years, the company has become the F2000car center products, as of the end of2009, F2000car production has exceeded50%。With the mass production models, we found that the mold process, the cold drawing in the stamping process has an impact on one of the main problems of product quality。In actual production caused due drawing crack, rounded cracking, pull marks and burr widespread occurrence of such phenomena。This study is a combination of Shaanxi Heavy Duty Truck Cab improve the quality of the company subject to the requirements.。 Drawing on theoretical knowledge, stretching pieces technological features, drawing parts quality problems were studied。Focus on product quality problems and process design and mold structure corresponding relations were important analysis。 The conclusions apply to the improvement of product quality improvement to go。This article will focus on drawing performance on the degree of influence product quality problems and find solutions。...
