Title
(EN) Method for producing internal tooth section and external tooth section on cylinder type hollow member with thin wall
(ZH) 用于在薄壁的圆柱形空心件上制造内齿部和外齿部的方法和装置
Abstract
(EN)
The invention relates to a method for cold-form profiling cylindrical, thin-walled hollow parts (1), comprising profiles which extend in an essentially parallel manner in relation to the longitudinal axis (A) of the hollow part (1). At least one profiling tool (5) engages in a strike-like hammering manner with the outside of the hollow part (1) in a radial manner in relation to the longitudinal axis (A) of the hollow part (1). The profiling tool (5) engages, respectively, in an essentially vertical and oscillating manner on the surface of the hollow part (1). Then, the profiling tool (5) is displaced in an axial manner in relation to the hollow part (1) at a constant radial adjusting depth until the desired profile length is obtained.

(ZH)

用于对圆柱形的薄壁的空心件(1)冷变形成型的方法,包括基本上平行于空心件(1)的纵轴线(A)延伸的成型部,其中径向于空心件(1)的纵轴线(A)从外面使至少一个成型工具(5)冲击式锤击地作用到空心件(1)上,使成型工具(5)分别在一基本上垂直的方向振荡地作用到空心件(1)的表面上。成型工具(5)在保持不变的径向进给深度下相对于空心件(1)轴向相对移动,直到达到要求的成型长度。
