Three kinds of man engine parts of China heavy truck have been produced in mass production
In recent years, three kinds of man engine parts (oil cooler cover, front cover shell, intake pipe) have been developed by China heavy steam organization, and the products have already entered the batch production stage. At the bottom of the spare parts manufacturing and processing department constantly Jiadaman product development efforts to develop new products, and strive to improve the processing level of product structure, improve equipment utilization, increase sales revenue.
Since the implementation of three kinds of man engine aluminum parts development, the processing Department has attached great importance to it, seriously organized and participated in the process of prophase planning, machine selection, process planning, tooling design and manufacture, tool manufacturing, fixture preparation, CNC machine tool preparation and so on. At the beginning of October, began the trial processing of three aluminum parts.
The technology sector during the trial for the deformation of the blank and blank insufficient margin to make further improvements: one is to add and reduce the occurrence of residual deformation; two is the intake pipe processing positioning surface milling is not complete, timely contact with the manufacturers to adjust tools, will be changed to fixed adjustable positioning, adjusted fully meet the processing position requirements. The three is to copy two sets of tooling and customize the internal cooling alloy bit to reduce the cutting time. Meanwhile, the increase of tool steel ensures the accuracy of machining hole location and improves the product quality.
