In order to accommodate large-scale production, the stability of the batch performance of the jacket material as a wire harness is also critical, and the frequent adjustment of the extrusion process due to the instability between batches is bound to affect the final performance of the automotive wiring harness. Poor quality of the jacket material, especially the recovery of sheathing material within each batch and between the batch and the batch is difficult to ensure its performance and stability, so in the extrusion harness jacket, the need to constantly adjust the process parameters, so Will ultimately affect the stability of the automotive wiring harness quality.
To achieve through the operation of graphics to modify the product information, but also requires the graphics information stored in the database and the product structure information one by one correspondence. When AutoCAD is not running, the graphics are stored in the file system, the objects contained in the DWG file are recognized by their handles. After the graphic is opened, the graphic information can be accessed through the graphics database and the handle of the graph remains unchanged.
There are several reasons for this problem: the first operator wiring and welding experience is insufficient; followed by the operator's sloppy, more important reason is the whole system of integrated wiring inspection means lack, although the test , But failed to find the problem in time. Therefore, in addition to improving the actual operation of the operator level and strengthen the process management, improve the detection technology is to improve the reliability of one of the main factors.
For automotive wiring harness, the mechanical properties need to consider the yield strength, tensile strength, elongation at break, wear resistance and so on. Also worthy of special attention is the PE jacket material mechanical properties of bulk stability and aging rate of change before and after.
Using the above method, combined with the characteristics of automotive wiring harness. Designed and developed for the enterprise car wiring harness CAPP system. Take the light CNC CNC control system harness as an example, for the product information input after the completion of the product structure of the local map, you can determine the length between the nodes, surface coating, terminal type, part number, access node, And other information. This information is always consistent with the product information in the database. You can easily understand the input of product information through graphics, or you can change the product information through graphical interaction.
