华中科技大学武昌分校本科毕业设计无凸缘圆筒工件模具设计No flange cylinder workpiece mold design 系 别：机电与自动化学院专 业 班：机电 0806 班姓 名：伍振江学 号：指导老师：燕2024 年 6 月摘要冲压是利用安装在冲压设备（主要是压力机）上的模具对材料施加压力，使其产生分离或塑性变形，从而获得所需零件的一种压力加工方法。这次拉深是利用模具使 10 号钢平板毛坯材料变成为开口的空心零件的冲压方法，用拉深工艺可以制成筒形件、阶梯形件、球形、锥 形、抛物面形、合形和其他不规则形状的薄壁零件。通过对一个阶梯形筒形件的拉深工艺计算，说明阶梯筒形件的拉深工艺的计算方法。用该方法计算确定的拉深工艺，可以 确保多次拉深过程中的拉深过渡形状不被拉断，最终拉出合格的工件。这里介绍了落料 拉伸，整形，切边等多套模具。用该方法计算确定的拉深工艺，使得模具设计、 加工精度与复杂性不断提高，模具制造工期不断缩短。关键词：筒形件 拉深工艺 整形 切边 AbstractSteel parts of the stamping process and die design Abstract The use of stamping is installed in the stamping equipment (mainly the press) on the mold to exert pressure on the materials to produce plastic deformation or separation, to obtain the necessary components of a pressure processing methods. Drawing is used to mold into a plate of 10 steelrough openings for the hollow parts stamping method, using drawing process can be made tube, ladder-shaped pieces, spherical, cone-shaped, parabolic shape, or other irregular shape and thin Wall components. Based on a ladder-shaped cylinder of the drawing process, that ladder tube drawing of the method of calculation. This method is determined by the drawing process, drawing on many occasions to ensure that the process of drawing the shape is not pulled off the transition and eventually pulled out of qualified workpiece. Here on the blanking stretch, repeatedly drawing, shaping, trimming, and other sets of mold. With the method of calcula...
