我厂生产的拉刀,有细圆柱形的,也有扁圆形的。为了减少热处理过程中的弯曲变形,一方面应从工艺上尽量保证减少弯曲变形的产生,另一方面应及时消除已产生的变形。拉刀的夹固冷却就是及时消除热处理过程中产生弯曲变形的一种好办法,既简单又省时,较其他方法减少拉刀弯曲变形行之有效,现将夹固冷却方法介绍如下: I broach production plant, a thin cylindrical, but also oblate. In order to reduce the bending deformation in the heat treatment process, on the one hand, the process should be as far as possible to ensure to reduce the generation of bending deformation, on the other hand, the deformation that has been generated should be promptly eliminated. Broach cooling broaching is the timely elimination of heat treatment during the bending deformation is a good way, both simple and time saving, compared with other methods to reduce broach bending deformation effective, now clamping cooling methods are described below:
