METHOD FOR PRODUCTION OF COPPER LONG BLANK |
| 摘要 |
FIELD: plastic metal working; may be used in production of cold-drawn articles from electrical copper on drawbenches provided with resistance welding machines. SUBSTANCE: after butt resistance welding of blank and trimming of flash, blank is subjected to local hot deformation, for instance, blank upsetting in axial direction within the zone of thermal effect of weld at temperature of 810-870 C to form local bulging on blank with diameter equalling 1.5-2.0 diameters of initial blank. After cooling, bulge is removed by the known methods. EFFECT: higher plastic properties of metal in zone of weld thermal effect due to reducing copper grains, and provision of use of long blank. 2 dwgh
