Maintenance and maintenance of electric screw presses

First, the maintenance of the gas system: the gas system once the leakage, will reduce the air pressure, so that some poor pneumatic action. Therefore, we should always check and replace the seal, adhere to the air pipe is normal. In addition, too much water in the air will rust the machine, resulting in solenoid valve and a variety of cylinder piston action is bad, it should be noted that the initial end of the air supply pipe near the equipment dehydration equipment, and often view the protection.

Second, the oil equipment maintenance: the relative rotation of the press and sliding some if the lack of oil, natural lead to burning, showing problems. Therefore, you should always check the fuel condition carefully, so that it insists on the outstanding situation. First, to see the fuel tank, oil tank, pump and other oil can be enough, there is no dirt; Second, check the oiling parts, oil piping, joints with or without oil spills, if any oil leakage need to replace the seal. Leakage of oil once attached to the clutch or brake, will affect its function, the formation of risk, it should pay special attention. In addition, the oil filter finishing, the installation of the solenoid valve before the oil mist of the oil, oil mist drops can be appropriate, are not lost matters.

Third, the clutch, the protection of the brake: to ensure that the clutch, brake action smooth and accurate, the gap between the conflict disk need to be aligned. The gap is too small or the conflict of the gear spline shaft slip bad, come back to break the spring, etc., will form a clutch, brake disengage, Conflict disk bumps, the occurrence of conflict sound, resulting in fever, so that the conflict piece wear, and the main motor current value increases, the conflict disk from the poor, or even show the second drop of the slider appearance. Clutch, brake action to be accurate, specify the location of the error in the range of ± 5 ° within the outstanding, if exceeded, it is necessary to adjust. This time should be seen: brake pads with or without wear, the move can be bad; clutch, brake pads can be attached to oil; cylinder piston seal with no wear and tear; air pressure can change; brake and clutch chain timing No being disrupted. Therefore, EP series electric screw press it is necessary to view and repair the operating circuit, the rotary cam switch, the solenoid valve and the air source.

Fourth, tighten the bolt repair: through a long period of time or overload, will make tightening bolts loose. Loose the appearance of the judge, as long as the press after the load, the investigation of the chassis base and column contact surface can have oil revenue and expenditure can be. There are oil revenues and expenditures, clarifying the tightening of the bolts. It is risky to carry out the press operation in the condition of tightening the tension of the bolt, and it is necessary to fasten it from the head. The amount of fastening can be determined by reference to the drawing.

5, other bolts loose correction: some of the bolts (including equipment attached to the device bolt) can be loose, it should be regularly check the matter, if loose should be tightened. Electric screw press stamping, oscillation, especially high-speed press, high oscillation frequency, the bolt loose fast. Loose bolts often lead to unpredictable incidents that need to be treated carefully.

Six, transmission system, electrical system and a variety of auxiliary equipment function check the repair. It is necessary to be included in the press operating procedures, before the daily operation, boot processing, after the operation, the corresponding items are intended to view and find the problem in a timely manner. deal with.

Seven, timing accuracy View: follow the use of time continuous, press the accuracy is also reduced. Therefore, it should be accurate to view the time, found that the accuracy of the early to make it recover, to avoid the impact of stamping products and mold life. Usually the minimum requirements of the press is to reduce the accuracy of a level, it is necessary to quickly revive rehabilitation, which also facilitate the subsequent quality management.
