Power press correction method

1. Clearance between slide block and guide rail

The clearance between the slider and guide rail is mainly adjusted for accuracy.Generally, each side of the minicomputer is 0.02~0.05mm, and each side of the mainframe is 0.03~0.20mm. 

2. Comprehensive clearance

Correction method of integrated clearance: during production, touch the slider body in motion by hand. When the slider runs to the bottom dead point, there will be a sense of vibration, indicating that the integrated clearance is too large and needs to be adjusted in time. 

3. Lock the slider connecting rod

As a result of long-term use or overload, the linkage will occur loose, this state is generally considered to have occurred overload;Then there is the combination of oil leaching may also be the occurrence of overload;This state must be adjusted in a timely manner, because this is related to safety issues. 

4. Maintenance of brake and clutch

Power press brake and clutch is an important part of a security operation, it is a major safety accident cause, so you have to understand its basic structure, and every day have to confirm its safety performance, "before the found anomalies (such as: the slider can't stop in the designated position, there is abnormal sound operation and abnormal vibration, the slider slow, etc.) report timely maintenance. 

In addition, maintenance personnel should also pay attention to the brake, clutch friction between if the gap is too large performance is: compressed air consumption increases, the press slider appears creeping state, serious will appear a continuous operation of the sliding block, this is absolutely not allowed to happen.So if the adjustment clearance is too small, the brake, clutch friction plate will produce friction sound, heat, motor current rise and other phenomena, but also will cause damage to the return trip spring.(normal clearance standard 1.5-3.0mm). 

5, secede

Disconnection generally occurs at the lower dead center, when the upper and lower die is closed, the slider cannot run normally.At this time, the motor can be made to reverse the operation and lift the pressure of air pressure in the air, the operation button will be set to the "inching" state, and the slider will be pulled up to the top dead point. 

6. Correction of bolt looseness

It includes the machine tool attached facilities of the bolt must be confirmed regularly, especially some high-speed frequent operation of the press should pay attention to, because these machine tool vibration is easier to loosen the bolt.Once the bolts loose, if not corrected in time, it will cause some unexpected safety accidents. 

7. Spot check of oil feeding device

Mechanical running part in the oil supply is not always often burn, bite so the oil part of the spot inspection must be implemented.It includes oil cup, oil tank, tubing, filter, oil seal and so on "run, run, drip, leak, plug" phenomenon must be dealt with in time. 

8. Inspection of compressed air

Machine tool compressed air pipeline leakage will cause low pressure and affect the machine action will occur, so must be repaired in time. 

The water content of the compressed air should also be controlled (can be installed air filter drying dehydration device), it is the machine tool solenoid valve, cylinder and other devices slow action and corrosion of the major inducement. 

9. Check the accuracy of the power press regularly

The accuracy of the power press will have a direct impact on the service life of the mold and the machining accuracy of the products.But the machine tool accuracy is with the extension of time and deterioration, so must regularly carry out precision spot check, found the problem to repair in time, in order to ensure that the machine has a more accurate precision, so as to ensure the accuracy of the products produced.
