SINGLE-CRANK PRECISION PRESS operation safety precautions
Operational safety of SINGLE-CRANK PRECISION PRESS:
1. The SINGLE-CRANK PRECISION PRESS clutch brake uses dual solenoid valves to control the action of the air pressure system. If one of the solenoid valves of the double solenoid valve fails, the air pressure system exhausts, and the running slider will stop suddenly. Or the air pressure system will not enter the air, the slider that has not yet started operation will not start to ensure the safety of the operators.
2. The electrical box door switch of this machine uses a breaker handle. To open the electrical box door, the power must be turned off, otherwise the box door cannot be opened.
3. The air pressure system of this machine is equipped with a pneumatic pressure detection device. When the pressure is lower than the set pressure, the pressure detection circuit will act, the slider will stop suddenly, and the green light will go out at the same time when the pressure is detected. Avoid the danger of operating the machine under insufficient pressure.
4. Photoelectric protection devices are installed on both sides of the machine. When the slider is running down, people or any object invades and blocks the grating of the light projector and the light receiver, the device will detect it immediately and make the slider stop urgently to achieve the safety function of protecting personnel and molds.
5. If the photoelectric protection function suddenly fails, the emergency stop light will be on except that the running slide will stop suddenly, or the slide that has not started running will not start. If damage is not ruled out, the slider cannot be started to ensure the safety of operators.
6. The press operator can be added to the process of maintaining the press so that they can remind the maintenance or management personnel at any time when there is a problem. They operate the press every day, so it is easier to hear or see the signs of problems. Just like driving the same car every day, you can notice abnormal noises in time, and this is the same for operators.
7. When the slider contacts the workpiece, the flywheel decelerates to a stop, and the stored rotational kinetic energy is converted into impact energy. Hit the workpiece with the slider to deform it. After the strike is over, the motor reverses the flywheel and drives the slider to rise and return to the original position. The specifications of the screw press are expressed by the nominal working force.
8. Check the fasteners and make up the missing parts. Check the clutch, spring and belt. Check the lubrication devices of the machine tool. Check whether the electrical circuit is damaged, aging, and whether the motor and electromagnet are normal.
9. Check the accuracy and wear of the crankshaft guide rail. Check the brake, clutch, slider, closing block, closing ring. Check the electrical control part. Detection and adjustment of the connecting bolts of the fuselage worktable.
SINGLE-CRANK PRECISION PRESS is used and safe to operate. After reading this article, you should have a basic understanding and understanding, I believe everyone understands it! In general, I hope it helps everyone.
