Straightening structure of six-roller straightening machine

The invention provides a straightening structure of a six-roller straightening machine, the straightening machine is provided with six straightening rollers, namely a 1 # roller, a 2 # roller, a 3 # roller, a 4 # roller, a 5 # roller and a 6 # roller, the 1 # roller, the 2 # roller and the 3 # roller are sequentially located above a straightening object, the 4 # roller, the 5 # roller and the 6 # roller are sequentially located below the straightening object, and the 6 # roller is located below the straightening object. And the height of the 2 # roller is lower than the height of the 1 # roller and the height of the 3 # roller. After a straightened object (a steel pipe or a bar) is straightened, due to the fact that the middle roller presses downwards, an outlet of the end of the straightened object is slightly warped upwards, scratching caused by friction between the end and an outlet guide plate can be effectively prevented, and the problem of straightening scratching is avoided. 本发明提供一种六辊矫直机矫直结构，所述矫直机具有6个矫
