ABSTRACT:
A method of manufacturing workpieces (6) and a device for effecting the same are related to the field of plastic metal working and can be used in the machine building industry. In order to improve the precision and strength of the workpieces (6) and to extend their service life, the workpiece blank is subdivided into heating zones, loading zones and cooling zones. The number of deforming steps is determined, the workpiece (6) is deformed under creeping conditions with stresses below the limit of elasticity, and, to avoid irreversible deformations, the stresses are relaxed. For this purpose, the thermal chamber (1) is provided with a multisectional housing (7) which has its sections (8) connected pivotally with each other where each section (8) has its own heater (2) and cooler (9), and within each of the zones a portion of the workpiece blank (6) is to be positioned which has the same geometrical and thermal physical properties throughout it.
