Lead cab BIW size bias affecting the two factors analyzed to propose ideas and solutions to solve the problem: 1, sheet metal design quality sheet metal design including overall quality benchmarks / tolerance of rationalization, stamping, Consistency three benchmarks. Reasonable basis / tolerance can reduce the accumulated error of sheet metal welding, stamping can increase overall productivity and reduce the number of sheet metal parts make the cab, so as to prevent the generation of cumulative error of welding processes, benchmarking consistency can ensure uniformity of sheet metal welding position, reducing the size of the fluctuations in the relative position. 2, the manufacture of precision sheet metal stamping dies is the main process equipment for the production of sheet metal parts, design quality and manufacturing quality stamping die directly affect the accuracy of sheet metal parts, sheet metal parts can cause deviations subsequent welding process deviations We said sheetmetal sheetmetal deviation is the deviation in the free state of each size and sheetmetal assembly nominal position of each dimension, related to sheet metal design, manufacturing variations and deformation produced during transport deviation manufacturing variations. His main reason for the deviation caused by the stamping process caused unreasonable, which is by itself sheetmetal geometry, material properties of the decision. For example, the shape of the sheet metal size, complexity of the process of drawing, mold structure and precision sheet metal forming properties. Heavy truck cab production line built after this has a production capacity of the process of the cab window, the general could not immediately reach the preset capacity. Additional, heavy truck cab for coating requirements certainly has grown, but until now there are still gaps and car coatings. Approximately 50% to 70% of the control room still thinks fit using two coating process (ie, the coating process is omitted). Because of this, in the previous stage preset according to three preset cab coating, the coating can be when you start line and the release of all of the relevant set to commence in the second phase. When producing a map of the cab, three coating process can be implemented to start painting painted by hand in the paint section. And then return to finish baking in the coating chamber spray paint spray paint. Phase I can not lose focus set in paint coating systems and air conditioning systems, while the second phase in the coating line until then filled these devices. Machinery Industry fourth preset Shaanqi hospital for pre-coating line of heavy trucks with a capacity of 20 / h. Thinking about the problem to reach the pre-production the previous stage, so set aside in the coating line is not started. Today, Shaanxi Auto heavy truck production and sales increase, without affecting the status of things produced in the coating line will start to complete.
