Abstract
The method for the manufacture of a fixed roller (1) for a fixed roller tool for the fixed rolling of radii or recesses on bearing pins and crankpins of crankshafts for motor vehicle engines provides for the following method steps: Turning of the body of the fixed roller (1) made of tool steel, Separation of the turned fixed roller (1), Smooth-rolling of the fixed roller (1) in the area (2) of its greatest circumference, Hardening of the smooth-rolled fixed roller (1), and Polishing of the hardened fixed roller (1).
Claims8
A method for the manufacture of fixed rollers (1), characterised by the following method steps:
- a) Preforming of the body of a fixed roller (1) by turning at the end of a cylindrical bar of tool steel,
- b) Cutting off the pre-formed fixed roller (1) from the end of the bar,
- c) Smooth rolling of the fixed roller (1) in the area (2) of its largest circumference,
- d) Hardening of the smooth-rolled fixed roller (1), and
- e) Polishing of the hardened fixed roller (1).
A fixed roller (1) for a fixed roller tool for the fixed rolling of radii or recesses on the main bearings or connecting-rod bearings of crankshafts of motor vehicles with an approximately truncated-cone shaped body, which is formed by metal-removing forming at the end of a cylindrical bar of tool steel, and is hardened and polished, characterised in that:
- The body of the fixed roller (1) is a turned part, and
- It is smooth-rolled in the area (2) of its greatest outer circumference.
