Abstract

The present disclosure 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:
shaping a metallic strip material with a shaping-hardening device, in which the strip material is shaped into a profile by a profiling roller;
hardening the profile during the shaping at least in certain regions;
emerging portions of the profile continuously from the shaping-hardening device providing a shape hardened profile;
cleaning the shape hardened profile;
heating a temperature of the shape hardened profile to a range between 25° C. and 300° C.; and
subsequent to the temperature adjusting, coating only a first portion of the shape hardened profile with a protective layer so that the shape hardened profile has both coated portions and uncoated portions, wherein the coated first portion of the shape hardened profile is at a lower risk of corrosion as compared to the uncoated portions.

2. The process according to claim 1 wherein the coating is performed in a coating device while a second portion of the profile is in the shaping-hardening device.

3. The process according to claim 2 wherein the metallic strip of material has cut edges; and wherein coating only the first portion of the shape hardened profile comprises coating exclusively the cut edges of the shaped hardened profile.

4. The process according to claim 2 , further comprising:
varying a thickness of the protective layer in the first portion.

5. The process according to claim 4 wherein the coating is performed by one of depositing or spraying on the protective layer.

6. The process according to claim 1
wherein the hardening comprises heating the profile one of inductively, conductively, with a naked flame or by contact heat.

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

8. The process of claim 1 wherein producing profiles comprises producing one of structural profiles and safety profiles.

9. The process of claim 8 wherein the profiles comprise motor vehicle profiles.

10. A process for producing profiles from metal, the process comprising:
shaping a metallic strip into a profile by a profiling roller in a shaping-hardening device;
hardening the profile during the shaping at least in certain regions;
emerging portions of the profile continuously from the profiling roller providing a shape hardened profile;
cleaning the shape hardened profile;
heating a temperature of the shape hardened profile to a range between 25° C. and 300° C.; and
subsequent to the temperature adjusting, coating only a first portion of the shape hardened profile with a protective layer so that the shape hardened profile has both coated portions and uncoated portions, wherein the protective layer further defines varying thickness including a thicker protective layer at portions of the protective layer particularly at risk of corrosion as compared to other portions of the protective layer less at risk of corrosion.

11. The process according to claim 10 wherein the coating is performed by one of depositing or spraying on the protective layer.

12. The process of claim 10 wherein producing profiles comprises producing one of structural profiles and safety profiles.

13. The process of claim 12 wherein the profiles comprise motor vehicle profiles.
