传统的辗沟工艺由于锻件沟位置的设计是以锻件宽度的中心对称线为基准,且锻件沟位设计基准与车削定位基准不统一,因此造成锻件沟位置精度较差及车削定位误差,使带沟辗扩工艺未能普遍推广。本文采用基准统一的设计原则,解决了上述沟位对称设计原则所带来的弊病,为带沟辗扩工艺的进一步推广创造了有利条件。 The traditional roller ditching process because the forging groove design is based on the width of the center line of symmetry forgings forgings, and the forging bit design benchmarks and turning positioning reference is not uniform, resulting in poor positioning of the forging groove accuracy and turning positioning error, so that the belt Rolling expansion process failed to generalize. In this paper, a unified design principle is adopted to solve the shortcomings brought by the principle of symmetrical design of gully position, which has created favorable conditions for the further promotion of the gouging technology.
