Six-fold type high precision straightener The main structure of the PTL30-1400-21 levelling machine includes a frame part, levelling machine wall panel, roller wheel, support roller, heavy duty upper and lower seat, displacement detection device, synchronous gear box, control system, transmission system, motor reducer, electrical control system and safety protection device.

Frame part.It is welded from high carbon steel plate and processed after high temperature tempering to ensure stable performance and dimensional accuracy of the frame. The main machine structure is the upper and lower two beams cross welded steel structure, anti-distortion, the active beam has enough steel and strength, to ensure the extremely high rigidity of the roller frame, can be high strength of the steel, to ensure the durability of the equipment and the steel plate leveling accuracy.

Panel section.For the main part of the leveler, the polished steel plate is polished after surface grinding, and the bearing position is processed with high precision by imported CNC computer gong to ensure the service life and ensure the processing accuracy.

Rolling.It is finished by Gcr15, and the hardness of the roller after finishing and reheat treatment is 60±2º. After grinding the surface of the roller, hard chromium plating and fine grinding, the surface of the hard chromium layer ≧0.1mm, the leveling roller can reduce the internal stress inside the part material to a minimum, which helps the material to be processed in the next process without obstacles, and ensure a constant quality of the final product. back-up roll The function of the support roll is to support the leveling drum and ensure that the leveling drum does not deform during the working stress. The upper and lower rollers have a number of groups evenly distributed in the middle, and the gap is adjusted before leaving the factory, and customers do not need to adjust. The support roll is composed of multiple roller bearings side by side, which has high precision and can withstand great force. The optimal number of support rollers supports the levelling roller, providing a particularly powerful support for the levelling roller to ensure a stable and repeatable levelling effect. The special design of the support roller and the design of the two bearing ensure the concentric operation of the support roller with high precision and improve the rigidity of the leveling roller. It also greatly reduces the straightening of the surface of the part caused by the support roller. No roll marks on material surface after leveling process! The bearing area of the support roller increases, and the overall height of the support roller is designed to facilitate the cleaning of accumulated debris!
