Beschreibung
Zusammenfassung:	FIELD: plastic working of metals, possibly thermal calibration of parts of bent and extruded shapes. ^ SUBSTANCE: apparatus includes housing having fastening cover strips and supporting surface. Die, punch and insert are arranged in housing. Working surface of insert is turned to punch; supporting surface of insert is defined by radius of supporting surface of housing. Insert is made of material having thermal expansion coefficient exceeding that of material of housing, punch and die. ^ EFFECT: enhanced reliability and quality of calibration due to transmitting uniformly distributed effort to punch. ^ 3 dwg
