Specially designed back pressure roller set, suitable for punching, unwinding and feeding of coils with material thickness of 0.6mm~6.0mm and width of 70mm~1600mm.
The material frame is made of four-blade design. The blade curvature is consistent with the inner diameter of the material. The surface of the blade is hard-plated, smooth and wear-resistant. It will not damage the material during use. The inner diameter is expanded by a rotary cylinder and hydraulically expanded. The roll reel adopts a wedge-shaped slider structure and adopts a drum brake to effectively prevent the material from spreading due to the rotational inertia during braking.
The feeding width is adjusted by the two-roller roller with the screw. When the material is discharged, the outer roller of the cylinder lifts the material to avoid the material, and the material is loaded and unloaded.
The correcting roller is made of high-alloy bearing steel and undergoes a series of heat treatments (tempering + high frequency treatment + hard chrome layer), strictly guaranteeing the rigidity of the correcting roller and correcting the surface finish of the roller to ensure the corrective material during the correction process. Surface properties, surface hardness of the correction roller up to HRC60, ensuring high precision and high wear resistance.
