7. Overload is strictly prohibited.
8. The lifting and reversing of the upper roller, the dumping reset of the bearing and the balance of the upper roller, must be carried out after the main drive stops.
9. It is forbidden to pile up workpieces and sundries in the work site, and keep the machine tools and the site clean at all times.
10, the operation is finished, should cut off the power supply, and lock the power box
The relationship between the operation efficiency and failure rate of mechanical equipment and the operator is very close. As the operator of dangerous equipment, we should know more about relevant knowledge in order to effectively avoid some misoperation or accidents due to the operator. Let us understand the details of the operation of the bending machine safety requirements. First the operator before the operation to tidy up around the operation environment, maintain a good operating environment, at the same time, the operator of the dress must be clean, avoid in the heart of the operation process of clothes Angle and so on into the roll in, in the process of work must pay attention to the operator can only stand in the position of the both sides of the workpiece is reasonable. If in the process of operation, to adjust the measurement of roundness, then must be shut down operation, do not operate in the process of operation. When the workpiece arrives, leave a certain margin. When measuring roundness, it is forbidden to stand on the rolled cylinder and stand on the workpiece to be machined. For some difficult processing of the workpiece: such as, thicker, or is larger in diameter, raw material hardness or strength is higher, should be through a small number of operations at the same time to be able to work through many times to achieve the effect. For some workpiece diameter is small, should be placed in the middle of the roll rolling operation.

The sealing performance
The use of any large and small enterprises or similar winding machine manufacturers of the factory this equipment must be in order to prevent leakage and dust in processing must be installed with sealing devices. Machine hydraulic system plays a sealing function components, namely seals, seal machine hydraulic system is used to prevent liquid or solid particles from leakage between adjacent joint surface, and prevent the impurities such as dust and moisture into the inside of the machine equipment materials or parts of the parts and components used in hydraulic system of machine seal leakage will cause the waste of working medium, Pollution of machines and environment, and even cause mechanical failure and equipment accidents. The reliability and service life of sealing parts in the hydraulic system of the winding machine is an important index to measure the quality of the hydraulic system. Besides gap seal, all is the use of seals, clearance between the adjacent two coupled surface control in need to seal the liquid can pass the clearance of the following, in hydraulic system of machine seals in the contact seal, usually divided into type sealing pressure tight seal and sealing type self-tightening sealing also calls the lip) two, however, The various sealing factors in the hydraulic system of the bending machine are different, just as the sealing of the three-roller bending machine is also affected by the different temperature pressure and the existence of the media.
