Cutting requirements and external force of two-roll straightener
In the process of using the two-roll straightening machine, it mainly processes and straightens some curved items. There will be two to three large pressure rolls as the main dynamic pressure rolls. The two-roll straightening machine is used in the motor. Rotate in the same direction under the belt.
The other end of the two-roller straightener is operated by several small rollers as driven pressure rollers. The rotation of these small rollers is rotated by the friction of the round bar or the pipe. According to the compression requirements of the product, the equipment must be adjusted in the front and rear directions at the same time.
In the process of using the two-roll straightening machine, in general, the more the number of sticks, the more precise the product will be straightened by the straightening machine. After the product is put into the two-roll straightening machine, the machine will It will continue to perform linear or rotational motion.
During the cooling and cutting process of the two-roll straightening machine, due to its uneven plastic deformation or uneven heating and cooling, it will inevitably produce different degrees of bending and wave-shaped plastic deformation, or internal residual stress.
The two-roll straightening machine uses a steel pipe to withstand a certain way and a certain amount of external force, which will produce a certain elastic-plastic deformation to a certain extent; when the above-mentioned external force is removed, it will produce elastic recovery deformation under the action of internal force. Until the internal force reaches a new balance, so as to obtain the required leveling effect;
