What should be paid attention to when using a rubber vulcanizing press?

The rubber vulcanizing machine is suitable for the vulcanization and pressing of various rubber and plastic products. The rubber vulcanizing machine generally adopts PLC control, with automatic and manual operation, and can record the required process flow, remote operation, and system management. So what safety issues should be paid attention to when using a rubber vulcanizing press?

Here is the content list:

What should be paid attention to before starting the rubber vulcanizing press?

1. Check whether each pipeline valve (handwheel) of the rubber vulcanizing machine is open. 2. Check whether the safety rod is sensitive and reliable. 3. Check whether the various factions of the rubber vulcanizing press are in the best condition. 4. Check the rubber vulcanizing machine program and vulcanized tire specifications. 5. Check the maintenance items. 6. Check whether the switch button on the operating keyboard meets the requirements. 7. Replace the recorder drawing of the rubber vulcanizing press. 8. Check whether the vulcanizing medium meets the process requirements.

What are the precautions for the rubber vulcanizing press when closing the mold?

1. The shaping pressure of the rubber vulcanizing press must meet the process requirements to prevent quality problems caused by improper shaping pressure.

2. When placing the small ticket, before the vertical movement of the beam, place it in the lower side mold where there is no word, do not press the exhaust line, and use it in the order of numbers. The single number is placed on the right mold, and the double number is placed on the left mold.

3. During the mold clamping process, the operator is not allowed to leave the rubber vulcanizing press. If abnormalities are found, immediately shut down for inspection.

4. Vulcanization safety protection device: the pressure indicator light is a safety reminder; the safety valve is installed on the steam chamber and is the model pressure relief device; the safety rod is used to prevent the dangerous parts of the rubber vulcanizing press from causing personal injury. Check once before the start of each class.

5. Alarm device: a reminder device set for the pressure of the steam chamber is too high and exceeds the set value.

6. Emergency stop device: emergency device can be used when it is disturbed or malfunctions.

7. Check the set pressure value of the rubber vulcanizing press when closing the mold. If it does not meet the timely adjustment when the delay is over and continue to mold, pay special attention to the gap between the movable module and the wall of the steam chamber when it is going down.

What are the precautions after the rubber vulcanizing press is closed?

1. Make all records. Record shifts, operators, mold clamping time, number of capsules, machine numbers, tire specifications, etc.

2. The internal pressure steam filled in the rubber vulcanizing press must meet the requirements (8±0.5kg/cm2), and the temperature must be greater than 170°C.

3. Check the rubber vulcanizing presses every 10 minutes:

Whether the temperature and pressure of the recorder are within the range of process requirements.

Whether the return water pressure, clamping force, condensate temperature, and steam chamber pressure meet the process requirements.

Focus on checking the process from the rubber vulcanizing presses to the standard temperature and pressure after the mold is closed.

4. Check the internal pressure cooling water, pressure, and temperature (10-15 kg/cm2, 30±5℃). If the pressure does not match, you can adjust the flow rate of the cold exhaust valve. If the temperature does not match, you can notify the relevant department to solve it.
