Abstract

The present disclsoure relates to a process for producing profiles from metal, a metallic strip material being fed to a shaping-hardening device, in which the strip material is shaped into a profile and is hardened at least in certain regions, portions of the profile that are emerging continuously from the shaping-hardening device being coated with a protective layer. The disclosure also relates to an apparatus for producing profiles from metal, with a shaping-hardening device for shaping a metallic strip material that can be fed to the shaping-hardening device into a profile and for hardening the profile at least in certain regions, and with a coating device, by which portions of the profile that are emerging continuously from the shaping-hardening device can be coated with a protective layer.

First claim

What is claimed is:

1 . A process for producing profiles from metal, the process comprising:
feeding a metallic strip material to a shaping-hardening device, in which the strip material is shaped into a profile and is hardened at least in certain regions; and emerging portions of the profile continuously from the shaping-hardening device wherein the portions are coated with a protective layer.

2 . The process according to claim 1 , further comprising:
coating a first portion of the profile in a coating device while a second portion of the profile is in the shaping-hardening device.

3 . The process according to claim 2 , further comprising:
coating the profile coherently.

4 . The process according to claim 2 , further comprising:
coating the profile incoherently.

5 . The process according to claim 2 , further comprising:
varying a thickness of the protective layer is varied from portion to portion.

6 . The process according to claim 5 , further comprising:
coating the profile by one of depositing or spraying on the protective layer.

7 . The process according to claim 1 wherein the portions of the profile that are emerging from the shaping-hardening device are cleaned before the coating.

8 . The process according to claim 1 , further comprising:
adjusting a temperature of the profile to above 25° C., in particular to the range between 25° C. and 300° C., before the coating.

9 . The process according to claim 1 , further comprising:
shaping the strip material in the shaping-hardening device into a profile by a profiling roller.

10 . The process according to claim 9 , further comprising:
hardening the profile in the shaping-hardening device one of during or after the shaping.

11 . The process according to claim 10 , further comprising:
heating the profile one of inductively, conductively, with a naked flame or by contact heat.

12 . The process according to claim 1 , further comprising:
cutting the profile to length into individual profiled components after the coating.

13 . An apparatus for producing profiles from metal, the apparatus comprising:
a shaping-hardening device for shaping a metallic strip material that can be fed to the shaping-hardening device into a profile and for hardening the profile at least in certain regions; and a coating device that coats portions of the profile that are emerging continuously from the shaping-hardening device with a protective layer.

14 . The apparatus according to claim 13 wherein the shaping-hardening device and the coating device are arranged one behind the other in such a way that the profile is conveyed through the shaping-hardening device and the coating device in the manner of an assembly-line process and thereby coated continuously.
