锥罩拉伸成形模的改进

Improvement of Drawing Forming Die for the Cone Cover

通过改进锥罩各次锥部拉伸模,并将锥罩各次锥部拉伸设备由机械压力机改为液压机,降低了金属材料变形速度,改善了压边装置,从而提高毛坯加工精度。通过锥罩各次锥部拉伸模的改进,解决了锥罩顶部圆角处出现壁厚变薄问题,提高了锥罩加工精度,降低了锥罩冲压加工废品率,节约了生产成本。

Through improved cone cover all the cones drawing die, and the cone cover all the cones stretching equipment hydraulic press by mechanical press instead, reduce the deformation of metal material speed, improved the blank-holder device, thus improve the rough machining accuracy. By cone cover all the cones the improvement of drawing die, solved the taper rounded on top cover thickness thinning problems, to improve the machining precision of cone cover, reduces the loss of cone cover stamping processing waste, saves the cost of production.
