Description

The present invention relates to a technique for straightening a bent pipe, and more particularly to a straightening device for straightening a multi-sized pipe material.

Conventional hydraulic stainless steel pipes or refrigerated copper pipes are wound in a coil shape, but in general, a part of the pipe is cut and discarded, straightened by a straightening device and formed into an almost straight straight pipe, and then the pipe line in the room. Piping and positioning work was done.

As a conventional straightening device, for example, in Taiwan Utility Model Publication No. M352409 (Patent Document 1), an electric motor (that is, a motor) is used as a power source to rotate a straightening roller group. By passing one bent reinforcing bar through the straightening roller group, the bent portion can be straightened. However, since the above-mentioned bending straightening device is large, it is inconvenient to carry, and the power consumption of the electric motor is large, so that the production cost is high.

Further, as another conventional orthodontic appliance, for example, in US Pat. No. 4,116,537 (Patent Document 2), two manually operated claws are used, and these claws are combined to form a cylindrical passage. The straightening work is performed by forming and arranging them facing each other and inserting a bent pipe into the passage. However, the frictional force generated when the pipe member comes into contact with the inner surface of the passage may prevent the claw portion from sliding on the pipe member. Further, in the worst case, if the frictional force is larger than the human power, there is a problem that the straightening device stops and does not move.

Therefore, there has been a demand for a straightening device that can be easily manually operated to straighten a straight line.
