PIPE BENDING MACHINE Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: device has two power-driven carriages 3 and 4, a number of bending units 5 and 6 mounted on them, and clamping and rotation mechanism 16, mounted between the carriages. The number of working positions for tubes in clamping and turning mechanism corresponds to the number of bending units mounted on one carriage. After carriages 3 and 4 having been set in working position, tubes are loaded and fixed in clamping and rotating mechanism 16. Bending is accomplished according to a program defining the tube configuration. After finishing the bending process, carriages 3 and 4 return to the initial position. Matrix rollers of the bending units are set into the load-unload position. The product is removed and then the cycle restarts. EFFECT: enhanced productive capacity, provided double- side bending. 2 cl, 12 dwg
