INSTALLATION FOR CRIMPING ENDS OF TUBULAR PRODUCTS Russian patent published in 1995 - IPC

FIELD: metal pressure forming. SUBSTANCE: installation performs high-efficiency production process due to using of units for feeding a tubular blank from a powered pocket, having two supporting rollers and one driving roller. The rollers are mounted on a platform, being driven by a drive mechanism and allowing to feed the tubular blank with any parameters to a working zone of two symmetrically arranged rollers. Such tool increases deformation rate without loss of lateral stability of the tubular blank. An original mechanism for extracting a ready article is in the form of a hollow rod of a power cylinder and a pneumatic cylinder, built in the hollow rod, both supporting a clamping head with cams for clamping a necking portion of the product. Upon axial motion of the hollow rod of the power cylinder the product is being carried to a receiving chute. From that chute the product is being transferred to a special container. EFFECT: enhanced efficiency of crimping process, enlarged manufacturing possibilities and lowered metal consumption. 1 cl, 10 dwg
