Abstract

PURPOSE:To obtain a titled device for bend-working a metallic strip material by a large radius of curvature, by utilizing a feed guide device of an existing hot vending device, and adding a device for suitably displacing the rotary center of a bending arm in 2 directions of right angles in the direction for feeding a material to said guide device. CONSTITUTION:This hot bending device is provided with a freely rotatable bending arm 3 which fixes a tip or intermiediate suitable place of a metallic material pipe 1 and guides it in the bending direction, a feed guide device 4 of the material pipe 1, a guide roller 5, etc. Also, said device is provided with a boom which moves a rotary center 7 of the arm 3 at some controlled speed v2 being slower than a feed speed v1 of the material 1 and also rocks freely centerring around pivot 8, and the rotary center 7 is controlled by a motor 10 so that the speed v2 is given by a chain 9. That is, the slower speed v2 than v1 is given to the center 7 agains the chain drawn to the right by thrust by said feed speed v1. Also, between the motor 10 and the chain 9, a worm speed reducer and a one- way clutch are provided, and after the bend-working has ended, the material is returned to the right end at a high speed by a motor 11 through the clutch.
