Product Details
Working Principle:
Roll Straightening: The straightening machine mainly extrudes bars, tubes, wires, plates, etc. through straightening rollers to change their straightness. Generally, there are two rows of straightening rollers, and the number varies according to the equipment type and straightening requirements. The driving pressure roller is rotated by an electric motor, and the driven pressure roller rotates by relying on the friction with the rotating round bar or tube. After the product is bitten by the rollers, it continuously makes linear or rotational movements, undergoing various deformations such as compression, bending, and flattening, and finally achieves the purpose of straightening.
Straightening by Angle Change (for specific types): For example, a two-roll straightening machine straightens materials of different diameters by relying on the angle change of the two rollers (concave in the middle and hyperbolic rollers).

Main Types:
Pressure Straightening Machine: It corrects the shape of materials by applying pressure to them, and is suitable for straightening various profiles and bars, especially having a better straightening effect on large and heavy materials.
Balanced Roll Straightening Machine: It utilizes the coordinated action of multiple balanced rolls to uniformly straighten materials and can better handle some materials with high requirements for straightening accuracy.
Shoe Roll Straightening Machine: The shape of its straightening rollers is similar to that of shoes, and it is suitable for straightening materials with specific shapes or special requirements, having good adaptability and straightening effect.
Rotary Reverse Bending Straightening Machine: It straightens materials by means of rotation and reverse bending, which can effectively eliminate the internal stress of materials and improve the straightening quality.
Roll-type Straightening Machine: It is widely used in steel rolling machinery and can be divided into various types according to structural characteristics, such as straightening machines for correcting shaped steel and steel pipes, and straightening machines for correcting medium and thick plates and thin plates.
Tensile Straightening Machine: It mainly achieves the purpose of straightening by stretching materials, and is suitable for situations where there are higher straightening requirements in the length direction of materials.
Tensile Bending Straightening Machine: It combines the advantages of roll-type straightening machines and tensile straightening machines. Under the combined action of the stretching of tension rollers and the continuous alternating and repeated bending of bending rollers, the material undergoes plastic elongation and is thus straightened.

Structural Composition:
Straightening Roller Device: This is the core component of the straightening machine, consisting of multiple straightening rollers. The number, diameter, and arrangement of the rollers will be designed according to different straightening requirements and material types. The surface of the straightening rollers is usually specially treated to improve wear resistance and friction against materials.
Drive System: It is used to drive the straightening rollers to rotate and is generally composed of an electric motor, a reducer, a coupling, etc. To ensure the stability and accuracy of the straightening process, the drive system needs to have sufficient power and speed adjustment capabilities.
Control System: It is responsible for controlling and monitoring the operation of the straightening machine, including starting and stopping the motor, adjusting the rotation speed, adjusting the position of the straightening rollers, etc. The control systems of modern straightening machines usually adopt automated control technologies such as PLC control and touch screen operation, which are convenient for operators to operate and monitor.
Rack: As the supporting structure of the straightening machine, it needs to have sufficient strength and stiffness to withstand the pressure and vibration generated during the straightening process. The design of the rack also needs to consider the convenience of equipment installation and maintenance.
Lubrication System: It provides lubrication for key components such as the bearings of the straightening rollers to reduce friction and wear and extend the service life of the equipment. The lubrication system usually includes components such as an oil pump, oil pipes, and filters.
Feeding and Discharging Devices: They are used to transport the materials to be straightened into the straightening roller device and output the straightened materials. The design of the feeding and discharging devices needs to ensure the smooth transportation of materials and avoid problems such as material jamming and scratching.

Technical Parameters:
Range of Straightening Materials: Different types of straightening machines can be applied to materials of different textures, such as steel, aluminum, copper, plastic, etc., and also have a certain applicable range for the diameter, thickness, length, etc. of materials.
Straightening Accuracy: It is an important indicator for measuring the performance of a straightening machine and is usually expressed by parameters such as straightness and flatness. The higher the straightening accuracy, the better the straightening effect of the straightening machine, but the cost and technical requirements of the equipment will also increase accordingly.
Straightening Speed: It refers to the length of materials that the straightening machine can straighten within a unit time. The speed of straightening will affect the production efficiency of the equipment. Generally, the straightening speed needs to be reasonably selected according to factors such as the type, size, and straightening accuracy requirements of materials.
Power of Main Motor: The power of the motor determines the straightening ability and running efficiency of the straightening machine. The larger the power, the larger the size and strength of the materials that can be straightened, but the energy consumption of the equipment will also increase accordingly.
