A steel pipe bending device with electromagnetic heating function

Abstract

The invention provides a steel pipe bending device with an electromagnetic heating function. The steel pipe bending device comprises a bending support system, a horizontal regulating system and a heating bending system, wherein a fixed driving die is connected with a driving die sliding wheel through a sliding wheel connecting block, a driving die regulating hole is arranged in the fixed driving die, an electromagnetic coil is arranged on the fixed driving die, a driving motor is fixed to a support base of the bending support system, the driving motor is connected with the fixed driving die through a driving motor rotating rod, and a diameter regulating die is connected with the outer wall of the fixed driving die. The steel pipe bending device has the beneficial effects that the bending precision of a steel pipe is effectively improved, and bending precision deviation caused by the internal stress of the steel pipe is avoided; and at the same time, the bending device can adapt to the use of a plurality of steel pipes and effectively increase the use range of the device.

Description

technical field [0001] The invention belongs to the technical field of steel pipe bending machine design, and in particular relates to a steel pipe bending device with electromagnetic heating function. Background technique [0002] In mechanical manufacturing, steel pipes need to be bent in many cases. Generally, steel pipes are bent manually. Due to the high rigidity of steel pipes, manual bending not only increases the labor intensity, but also reduces the labor intensity. efficiency. [0003] For example, the patent CN204247780U steel pipe bending device specifically relates to a steel pipe bending device; it includes a hollow bending seat on which a fixed platform, a steel pipe clamping groove and a steel pipe bending mechanism are arranged. The steel pipe bending mechanism includes a center wheel, a rotating The side ring of the center wheel is provided with a first elbow groove, and the side of the rotating wheel is also provided with a second elbow groove. The center...

[0003] For example, the patent CN204247780U steel pipe bending device specifically relates to a steel pipe bending device; it includes a hollow bending seat on which a fixed platform, a steel pipe clamping groove and a steel pipe bending mechanism are arranged. The steel pipe bending mechanism includes a center wheel, a rotating The side ring of the center wheel is provided with a first elbow groove, and the side of the rotating wheel is also provided with a second elbow groove. The center wheel is connected to the motor through a shaft, and the motor is arranged inside the bending seat. The end of the groove is provided with a fixed block, and the spring is fixed at the other end of the fixed block, and a reset block is set on the steel pipe clamping groove. One side of the seat is provided with a steel pipe connecting piece and a bending forming groove, the steel pipe connecting piece includes a connecting seat and a bending pipe mechanical arm, and the bending forming groove is arranged between the bending seat and the connecting seat; with the steel pipe bending device, although It is easy to take out the bent pipe and improve work efficiency. However, during the bending process of the steel pipe, the steel pipe itself has stress, and it is easy to rebound under the action of the stress after the steel pipe is removed, which will easily cause the bending size of the steel pipe to be wrong.
