在汽车拖拉机制造行业,三角花健拉刀在生产上应用较广泛,但在三角花健拉刀的设计上并没有新的改进。随着产品质量的提高,有必要对三角花健拉刀的设计进行改进。众所周知;按常规设计的三角花健拉刀,在加工过程中存在的主要问题是:拉刀没有侧后角或该角几乎等于零度,致使拉刀处于极不利的条件下进行切削。这样,势必引起拉刀齿侧表面与花健槽表面之间产生剧烈的摩擦,特
In the automobile tractor manufacturing industry, Triangle Hua Jian Broach is widely used in production, but there is no new improvement in the design of Triangle Hua Jian Broach. With the improvement of product quality, it is necessary to improve the design of Triangle Flower Broach. As we all know; according to the conventional design of the triangular flower-knives, in the processing of the main problems are: Broaches no lateral clearance or the angle is almost equal to zero, resulting in the broaches in extremely adverse conditions for cutting. In this way, it is bound to cause a sharp friction between the tooth broach side surface and the flower-groove surface, especially
