1. Check whether the mechanical properties are good, the workbench and the bending machine table are kept level; and prepare various mandrel tool stops.
Second, according to the diameter of the processed product and the requirements of the bending machine, the mandrel, the forming shaft, the iron retaining shaft or the variable retaining frame are installed, and the diameter of the mandrel should be 2.5 times the diameter of the product.
Third, check the mandrel, the block, the turntable should be free from damage and cracks, the protective cover is fast and reliable, and it can be operated only after the operation of the empty machine is confirmed.
4. When working, insert one end of the product into the gap where the turntable is fixed. The other end of the bending machine is fixed against the fuselage and pressed by hand. Check that the fuselage is fixed and it is safe to block the side of the product. start.
5. It is strictly forbidden to replace the mandrel, change the angle and speed control during the operation, and do not add or remove oil.
6. When bending products, it is strictly forbidden to process the diameter, number of roots and mechanical speed of the product exceeding the mechanical specifications.
VII. When bending high hardness or low alloy products, the standard diameter should be changed according to the mechanical nameplate and the corresponding mandrel should be exchanged.
8. It is strictly forbidden to stand in the working radius of the curved product and on the side where the fuselage is not fixed. The bent semi-finished products should be stacked neatly and the hooks must not face upwards.
9. When the turntable is reversed, it must be carried out after stopping.
Ten, the operation is completed, the site is cleaned, the machinery is maintained, and the lock box is turned off.
