Abstract
In a method of manufacturing articles (8) in hardenable metal materials, a shaped workpiece (5.1, 5.2) with closed cross-section is hardened. The hardened workpiece (5.1, 5.2) is separated into at least two parts, where each part constitutes one shaped open cross-section. The invention also concerns a manufacturing process and a production line for the manufacture of articles (8) in hardenable metal materials.
Claims10
Method of manufacturing articles of hardenable metal materials comprising the steps of:
- (a) providing a shaped workpiece with closed cross-section;
- (b) hardening the shaped workpiece to create a hardened workpiece by heating and subsequent quenching;
- and
- (c) dividing the hardened workpiece longitudinally into at least two parts, where each part constitutes one shaped and hardened article with an open cross-section.
Manufacturing process for the manufacture of articles of hardenable metal materials, comprising the following steps in the order named:
- (a) hardening a shaped workpiece with closed cross-section by heating and subsequent quenching;
- and
- (b) separating the shaped workpiece longitudinally into at least two parts, where each part constitutes one shaped and hardened article with open cross-section.
Production line for the manufacture of articles of hardenable metal materials comprising:
- (a) means for joining shaped sectional elements to obtain a workpiece;
- (b) means for hardening the workpiece by heating and subsequent quenching, the means for hardening following the means for joining;
- and
- (c) means for dividing the workpiece longitudinally into at least two parts, where each part constitutes one shaped and hardened article with open cross-section, and the means for dividing being immediately adjacent the means for hardening so that the work performed by the means for hardening and the means for dividing is carried out sequentially.
