METHOD AND DEVICE FOR DEFORMING CLUTCHES MADE FROM ALLOYS WITH PLASTIC MEMORY Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: method involves cooling clutch from its end side and simultaneously introducing deforming tool into clutch; providing simultaneous displacement of cooling zone and tool acting zone, with temperature in acting zone being maintained within the range of starting and final stages of martensite transformation process. Device has vessel 1 for coolant, deformation tool 5 rigidly fixed in vessel 1, stop 8 disposed above drift pin 3 and connected with power drive 11 providing reciprocating movement of drift-pin 3 in vertical plane. Device is further provided with temperature detector 13 mounted in vessel 11 in fixed position above working part 5 of drift-pin 3 and power drive control system 14 connected with temperature detector 13. EFFECT: increased efficiency and enhanced reliability in operation. 2 cl, 3 dwg
