The equipment that uncoils stainless steel coils and cuts them into complete strips of the required width is called a slitting line set. Metal coil uncoiling, stretch straightening, disc cutting, tension control and rewinding. The slitting line group is suitable for processing cold-rolled and hot-rolled carbon steel, silicon steel, tinplate, stainless steel, copper, aluminum and other non-ferrous metals and various metal materials after surface coating. The slitting line group production line is mainly composed of the slitting machine production line, including: feeding trolley, uncoiler, straightening machine, slitting machine, rewinder, tensioner, rewinder, unloading device, etc. The slitting line group is an indispensable equipment processing center for the shearing machine.
After the square roll is straightened by the decoiler and straightening machine, it is directly sent to the disc slitting line group by the pinch feeding device for longitudinal full-roll shearing. Then through the constant tension device, synchronous speed and speed limit control, the best coiling effect can be achieved.
Slitting line group
In the slitting line group, the disc blades are staggered on the upper and lower tool holders through various factors such as spacers of various sizes, thickness and width of the raw materials to be processed, etc. Then the power transmitted by the DC motor (servo motor) and universal joint causes the disc blade to move in a circular motion for longitudinal cutting.
During load operation, the winding diameter gradually changes. Due to the change of the coil diameter of the slitting line group, in order to maintain the load operation, the output torque of the motor needs to change with the change of the coil diameter.
Since the unwinding speed will gradually change with the processing process (the unwinding will become smaller and smaller, and the rewinding will become larger and larger.), the linear speed of the entire unit can be adjusted through PLC and synchronous frequency converter. In order to meet the accuracy of cutting and winding effects, generally speaking, the unwinding speed of the slitting line group is from slow to fast, the speed of the disc shear is generally synchronized with the unwinding speed, and the rewinding speed is controlled by the tension device. Adjusted by fast and slow winding effects. The speed of these three sections must be synchronized with the linear speed of the entire slitting.
In the slitting line group, the slitting machine blade is an important part of the tool holder and has high processing accuracy. For flat surfaces, it is necessary to use a surface grinder and grind them through special grinding methods, and through strict quality control to ensure that the thickness and flatness of all finished products are within 0.003 mm.
In the slitting line group, the complete set of slitting knives for disc spacer rubber rings also includes spacers, gaskets and other parts. Its main purpose is to maintain a certain width between the circular blades and adjust the horizontal gap between the upper and lower blades. The thickness of ordinary gaskets ranges from 0.8 mm to 150 mm. Regardless of thickness, its hardness is above HRC45, scratch-resistant, and its shape is sturdy and durable. The thickness tolerance is also required to be within 0.003mm, and the inner and outer surfaces are blackened to effectively improve the anti-rust performance.
