在我们所碰到的各种各样的拉深件中往往有很多零件需要采用多道工序才能得以完全成形,但我们总是力图寻找并通过各种途径和渠道,希望能以最少的拉深次数来达到所需要的各种形状。为了实现这一目的,则往往需要我们在工序分布和工序设计以及模具设计中必须经过反复的思索和探讨。除了尽可能地通过改变各种工序中的状态分布来减少工序,以及改变拉深的条件、润滑、拉深速度和模具的设计,制造质量以外,有时往往还可以利用零件上特有的条件,或者是 Often, there are many parts of the various drawing parts we encounter that require multiple processes to be fully formed, but we are always looking for and through various avenues and channels, hoping to minimize drawing The number of times to achieve the desired shape. In order to achieve this goal, we often need us in the process distribution and process design and mold design must be repeated thinking and discussion. In addition to reducing the process as much as possible by changing the state distribution in various processes and changing the conditions of drawing, lubrication, drawing speed, mold design, and manufacturing quality, it is often possible to utilize part-specific conditions or Yes
