The straightening principle of the straightening system of the rocker cutting machine is as follows:

The straightening principles mainly include reverse bending straightening, tension straightening, tension bending straightening and rotation straightening. Rotary straightening is mainly used for round bar straightening. The most common methods are hole mode straightening and inclined roll straightening. Both adopt the way of round bar rotating forward.

In rotary straightening, hole mode straightening is the earliest straightening method. Its characteristic is to use the rotation of the hub instead of the rotation of the round material to achieve the same straightening purpose. It is suitable for the straightening of the disc material, but its disadvantages are: large friction loss; Large consumption of hole mould; Round wood surface is easy to be damaged; Head feeding is difficult; Great rotational friction; The tail of the disc often rotates with the hub and cannot be straightened by the straightening system of the cutting machine; When the feeding is blocked, the hole die will grind the strip.

Inclined roll straightening is a straightening method developed later. This method is that the contour of the straightening roll is designed into a double curve shape, and is installed in the drum after tilting an angle centered on the contact point between it and the reinforcement. In the process of straightening, the straightening roller rotates around the axis of the rolling element and its own axis at the same time, so that there is no scratch on the surface of the reinforcement and good straightness; Improve production efficiency, save power and reduce noise. It overcomes the disadvantage of hole mode straightening.

In use, due to various wear, erosion, fatigue, deformation, aging and other phenomena of parts, the accuracy and function are reduced, affecting the product quality. When the situation is severe, the equipment will be shut down. Cutting machine maintenance is a technical flow adopted by maintaining and repairing the machine, reducing its deterioration, prolonging its service life, and maintaining or restoring the specified function of the machine.

The maintenance of rocker arm cutting machine includes equipment inspection, adjustment, lubrication, timely handling and speech in case of abnormalities, etc. In order to ensure the normal operation of the machine, reduce wear, protect accuracy and prolong service life, reasonable lubrication, maintenance and maintenance are necessary.
