"The Steel Coil Slitting Machine is designed to process metal coils with thicknesses ranging from 0.3 to 3MM, and through the design of sharp slitting blades, the metal coils are slit into the widths specified by the customer and finally wound up.The Steel Coil Slitting Line helps customers in the metal processing industry to efficiently produce secondary processed metal with high quality. coils for sale and use in the marketplace. How to turn on the Steel Coil Slitting Machine and adjust the Coil Slitting Machine?"
1. Steel Slitting Machine Inspection And Preparation
Before using the steel coil slitting line, the operator needs to perform a routine inspection of the steel coil slitting line and ensure that it is in proper working condition. Power supply check: check whether the electrical system and power supply are normally connected to ensure that the equipment is in an operable state. Hydraulic system check: check the oil volume of the hydraulic system to ensure that the hydraulic station is working properly and the oil circuit is smooth. Mechanical inspection: check whether the mechanical parts are loose, especially whether the key parts such as slitting knives, rewinding shafts, unwinder tension device are intact.
2. Loading And Uncoiling
The coils are transported to the uncoiler by means of loading trolleys or traveling cars. Lift the steel coil on the tensioning shaft of the unwinder and tighten the coil through the hydraulic system to prevent the coil from sliding during the unwinding process. Start the uncoiler, control the speed of uncoiler, unfold the steel coil gradually, and send it to the leveler section. Pay attention to adjusting the speed during the uncoiling process to avoid damage to the sheet or disorganization of the coil due to too fast uncoiling.
3. Leveling Operation
According to the thickness and hardness of the steel plate, adjust the working roll pressure and roll gap of the leveling machine. For thicker steel plates, the roller pressure of the leveling machine should be increased appropriately, so that it can effectively remove the internal stress and wave deformation of the material to ensure flatness. By adjusting the position of the leveling rollers, the steel plate can achieve better flatness when passing through the leveling machine, providing better conditions for subsequent slitting.
4. Metal Slitting Operation
After the steel plate passes through the leveler, it enters the steel slitting machine for longitudinal cutting. According to the customer's demand, adjust the knife shaft position and blade spacing of the slitting machine to ensure that the steel plate is divided into the required width. The setting of the blades should be reasonably configured according to the thickness and material of the steel plate to avoid damage to the blades or uneven slitting. Start the steel slitting machine and set the appropriate cutting speed to ensure that the metal slitting operation is smooth and the cutting surface is neat. If you find burrs in the slitting process or uneven cutting surface, you should stop the machine to check the blade wear or adjust the metal slitting tool gap.
5. Rewind Or Stacking
According to the production requirements, the slit steel plate can be either wound or stacked. Start the winder to roll the slit steel strip into multiple small rolls and use the tension control system to ensure that the strip is neatly wound. If the material is thin, reduce the winding speed to avoid wrinkling of the coil. If you need to stack the slit steel sheets, you can use the automatic stacking equipment to stack the steel sheets neatly at the designated location for subsequent processing or transportation.
6. Shutdown And Maintenance Steel Coil Slitting Line
At the end of the operation, stop the steel coil slitting machine correctly and do routine maintenance. Step-by-step shutdown: Stop the unwinding, leveling, slitting and winding equipment in sequence to ensure a smooth end to each process. Steel Slitting Equipment cleaning and inspection: Clean the blades, rollers and conveyors to ensure there are no residual steel sheet chips or debris to avoid affecting the next production. Regular Maintenance: Regularly check the hydraulic system and lubrication system to keep the equipment in good working condition to avoid affecting the production efficiency due to lack of oil or wear and tear of parts.
7. Common Problems And Treatment
Deflection problem: If the steel plate deflects during the metal slitting process, the leveling roller or centering system should be adjusted in time to ensure that the centerline of the steel plate is aligned with the blade of the steel slitting machine. Slitter burr: If the burr is too big after slitting, it may be that the blade gap is not set properly or the blade is worn out, so the blade needs to be readjusted or replaced. Rewinding is not neat: Rewinding is not neat usually related to improper tension setting or rewinding shaft gap, the tension control system should be adjusted appropriately.
The use of Steel Coil Slitting Line involves multiple steps, from loading and leveling to slitting and winding, each of which requires precise operation and adjustment. Reasonable settings and regular maintenance ensure the efficient operation of the equipment and improve the slitting accuracy and production efficiency. When problems are encountered in production, the equipment parameters should be analyzed and adjusted in a timely manner to ensure the quality and processing accuracy of steel plate slitting.
