1. During the operation of the metal slitting machine equipment, if there is a problem of transverse oscillation of the tool, then it will lead to the production of poor dimensions, such as the transverse oscillation of the tool and the outer diameter of the tool size is different and poor.
2. During the production of the metal slitting machine, there is a problem of transverse war-page of the steel plate, which results in poor width dimensions. This is due to the fact that the measurement of the product cut in the state of transverse war-page is large than the set value of the tool.
3. Is due to the production of metal slitting machine, which spacer set, knives, etc. There is a certain matching error. Usually, the spacer, tool thickness accuracy of 0.005. When the number of pieces is large, the cumulative error becomes larger.
4. Is due to the upper tolerance setting is bad. It is important to know that the width of the product cut by the metal slitting machine is always slightly lower than the product side dimensions of the matching knife tolerance state. Therefore, it is necessary to anticipate the extent of this lower tolerance in advance. In the product side of the knife time spacer size determination reference.
5. To take into account the shear method used. In comparison, if the metal slitter equipment adopts the straight pull type shear, then the tension of the steel coil is increased, the transverse war-page will disappear, and the size will go down to the poor.
For the above reasons, can be improved by the following methods:
1. Maintain and service the metal slitting machine regularly to ensure the normal operation and precision of the equipment.
2. Strengthen the training of operators to ensure that they are familiar with the correct operation methods and steps.
3. Select high-quality metal materials and conduct quality tests to ensure that the materials are uniform and free of defects.
4. Regularly check and replace the knives of the metal slitting machine to ensure its cutting force and precision.
5. Control the environment where the metal slitting machine is used to avoid being affected by temperature, humidity and other factors.
