Method and device for post-processing a hardened metallic shaped part by means of electrical resistance heating

The invention relates to a method for post-processing a formed and hardened component from a metallic material, by means of a device for electrical resistance heating, comprising at least a first pair of shaped contact pieces 4, 5 and at least a second pair of shape contact pieces 44, 45; Contacting a to be heated first portion 6 of the component 3 with the form of contact pieces 4, 5 of the first pair such that the first part to be heated region 6 between the mold contact pieces 4, 5 of the first pair is disposed; Contacting a second portion 46 of the component 3 with the form of contact pieces 44, 45 of the second pair such that the second portion 46 is disposed between the mold contact pieces of the second pair; Heating the first portion 6 of the component 3 to a first temperature T1 in that electric current by means of the first pair of contact pieces 4 form, is passed through the component 3 5; Tempering of the second portion 46 of the component 3 by means of the second pair of shaped contact pieces 44, 45 to a second temperature T2 that is set independently of the first temperature T1.
