Problems solved by technology
[0002] The metal pipes bought from the market, some defective products may not be straight, and the metal pipes are also prone to bending and deformation during transportation; if they are used directly, it will affect the quality of the subsequent processed products, so It is necessary to straighten the metal pipe, and there are some straightening machines in the prior art, but they all straighten the metal pipe by rolling the roller, but this operation requires high pressure and angle of the roller, and the cost is high , and the efficiency is low, the prior art has not solved such a problem

Embodiment Construction
[0016] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.
[0017] The metal pipe 1 straightening machine includes: a heating element wrapped around the metal pipe 1, a clamping assembly for fixing the metal pipe 1, a rotating assembly connected to the clamping assembly and driving the metal pipe 1 to rotate; the clamping assembly consists of: four A clamping rod 3 that is at right angles to each other and is clamped on the inner wall of the metal pipe 1.
[0018] In order to prevent the clamping rod 3 from breaking away from the metal pipe 1 during the rotation process, the outer wall of the clamping rod 3 is covered with an anti-slip sleeve 4; as a preference, the anti-slip sleeve 4 is a rubber sleeve, and of course it can also be made of other materials. All within the protection scope of the present invention to anti-slip effect.
[0019] The rotating assembly consists of: a connecting plate ...

The invention discloses a metal pipe straightening machine. The metal pipe straightening machine comprises a heating part wrapping at the periphery of a metal pipe, a clamping assembly for fixing the metal pipe, and a rotary assembly which is connected to the clamping assembly and is used for driving the metal pipe to rotate; the clamping assembly is formed by four clamping rods which form right angles with one another and are clamped at the inner wall of the metal pipe. The invention provides the metal pipe straightening machine using the tension of the metal pipe for rotary straightening; the metal pipe is firstly heated before the rotary straightening is performed, the tension and extension strength of the metal pipe are increased, and the metal pipe is clamped by a clamping device with uniformly distributed force, so the machined metal pipe is uniform and smooth, the straightening efficiency is high, the product quality is good, and the cost is low.
Description
technical field [0001] A straightening machine, in particular a metal tube straightening machine. Background technique [0002] The metal pipes bought from the market, some defective products may not be straight, and the metal pipes are also prone to bending and deformation during transportation; if they are used directly, it will affect the quality of the subsequent processed products, so It is necessary to straighten the metal pipe, and there are some straightening machines in the prior art, but they all straighten the metal pipe by rolling the roller, but this operation requires high pressure and angle of the roller, and the cost is high , and the efficiency is low, and the prior art has not yet solved such a problem. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a metal pipe straightening machine which utilizes the tension of the metal pipe to perform rotary straightening.
