Horizontal Easy Operation Round Bar Bender Automatic Moulding
Round Bar Bender
Safety Operation of Round Bar Bender:
1. Strictly abide by the safety operation rules of machine tools, and wear labor protection articles according to the provisions.
2. The upper and lower molds should be cleaned and wiped clean before starting.
3. Check whether there are foreign bodies on the supporting frame, retaining frame and sliding block. If there are foreign bodies, they should be cleaned up.
4. According to the thickness of the folded sheet, choose the appropriate die mouth, die mouth size is generally equal to or greater than 8 times the thickness of the sheet.
5. The bending force of the workpiece is obtained from the bending force number of the sheet or the bending force calculation formula. The bending force of the workpiece shall not be greater than 1000KN.
6. When bending the narrow sheet, the working pressure of the system should be properly reduced to avoid damage to the mold.
7. When adjusting the stroke of the slider, it should be ensured that the adjustment amount is less than 100 to avoid damage to the machine.

Matters need attention of Round Bar Bender:
1. Before bending, the clearance between the upper and lower molds should be adjusted uniformly.
2. When bending, do not put your hand between the molds, long and narrow materials can not be held by hand. Bend only one piece of material at a time, not many pieces of section bending at the same time. Check the oil level of the oil tank and start the oil pump to check whether there is any abnormality in the liquid pressure pipe and oil pump.
3. Bending sheet should be placed in the middle of the mold, the machine should not be unilateral load, so as not to affect the workpiece and machine accuracy, such as some workpiece really need unilateral work, the load shall not be greater than 250KN, and must be bent at the same time.
4. Check the oil level of the oil tank and start the oil pump to check whether there is any abnormality in the hydraulic pipeline and oil pump.
5. Stop the machine immediately if any abnormality occurs, check the cause and eliminate it in time.
6. After the operation, the oil pump should be shut down, the control system should be quit, and the power supply should be cut off.
