具体实施方式：Detailed ways:

下面结合实例对本发明做进一步的描述：The present invention will be further described below in conjunction with example:

实施例1：Example 1:

首先对转轴座进行加工，其加工方法是，转轴座圆导滑面角度多数大于180度，即存在负角，采用现有的三维偏置加工策略，方向沿着轴向加工，精加工行距0.3-0.5mm，把加工部分结合负角情况分成多个区域，用万能头摆角加工，加工后圆导滑面公差基本达到型面±0.03MM的要求，然后配车转轴，再把转轴及转轴座和相关件组装底板上.为了使转轴在转轴座里能旋转自如，把转轴两端限位面单边空开0.05mm；转轴座圆导滑面局部R较小，加工到位需用φ6刀清根，实际加工时，我们只清根到φ10，减少其它小刀清根，对于转轴相对应部分加工成R6空开，这样既方便加工，又节省时间，同时也保证了加工要求再对转轴翻边型面进行加工，其方法是，首先用立轴加工能加工到部分，然后把转轴在转轴座里旋转到靠死状态，用工艺螺钉固定，拆掉转轴盖板或其它干涉件，再用万能头摆角加工负角型面，使用行切加工策略，精加工行距0.3-0.5mm。First, the shaft seat is processed. The processing method is that the angle of the circular guide sliding surface of the shaft seat is mostly greater than 180 degrees, that is, there is a negative angle. The existing three-dimensional offset machining strategy is adopted, and the direction is along the axial direction. The finishing line spacing is 0.3 -0.5mm, the processing part is divided into multiple areas combined with the negative angle, and the universal head is used for processing. The seat and related parts are assembled on the bottom plate. In order to make the rotating shaft rotate freely in the rotating shaft seat, the limit surfaces at both ends of the rotating shaft are unilaterally opened by 0.05mm; the partial R of the circular guide sliding surface of the rotating shaft seat is small, and a φ6 knife is required to process it in place. Cleaning, in actual processing, we only clean the root to φ10, reduce the number of other small knives, and process the corresponding part of the rotating shaft into R6 open, which is convenient for processing and saves time, and also ensures the processing requirements before turning the rotating shaft The method of processing the edge surface is to firstly process the part with the vertical axis, then rotate the shaft in the shaft seat to the dead state, fix it with the process screw, remove the shaft cover or other interference parts, and then use the universal The head swing angle is used to process the negative angle profile, using the line cutting machining strategy, and the finishing line spacing is 0.3-0.5mm.

转轴机构工作时，用上翻边镶块使翼子板翻边后，滑块退回行程，利用气缸推动转轴，使转轴在转轴座里旋转一定角度后，达到使板料能退出的目的，然后转轴重新旋转到工作状态，进行下一轮冲压。When the rotating shaft mechanism is working, after the upper flanging insert is used to flang the fender, the slider returns to the stroke, and the cylinder is used to push the rotating shaft, so that the rotating shaft rotates at a certain angle in the rotating shaft seat to achieve the purpose of allowing the sheet to exit, and then The rotating shaft re-rotates to the working state for the next round of stamping.
