Research on Control Defects Method of Pits and Bulges in Stamping Surface of Truck Roof

Pits and bulges are one of the common quality defects of stamping parts. Because the reintegration will increase the cost of the whole vehicle, it is necessary to use reasonable methods to solve and prevent it. This paper analyzes and introduces the causes of pits and bulges defects in the various surface defects of truck roof in the stamping production process, describes the detection methods of pits and bulges defects, and discusses the production in stamping production. Measures to prevent pits and bulges defects. It has the same reference value for surface defect control of various body stampings.
