WIRE PLASTIC DEFORMATION MACHINE Russian patent published in 2010 - IPC B21F35/00 

FIELD: process engineering.

SUBSTANCE: invention relates to machine building and can be sued to produced coiled bending springs. Machine 1 comprises frame 4, wide feed device and wide transfer line to feed wire 3 into working zone of machine 1, wherein wire is subjected to plastic deformation by one or several tools (15, 17, 18). Each tool can displace relative to wire 2 from initial position to working position and is fitted on tool plate 7 mounted on frame 4 around recess 14, through which wire is fed into working zone, and rigidly fixed on tool plate 7 in feed direction. Tool feed is performed by displacement of tool plate 7 arranged on second plate 8 with recess 15 corresponding to recess 14 on tool plate 7 that can move along first direction (x) over second plate 8 which can move over frame 4 along second direction (y) perpendicular to first direction (x). Each of said directions is located at 45° to vertical axis (H-H) of machine 1.

EFFECT: simple design and high efficiency.
