500 Ton Rubber Plate Vulcanizing Machine For Rubber Elastomeric Bearing

Rubber Machinery Manufactruer 500 Ton Vulcanizing Machine For Rubber Elastomeric Bearing

Why Vulcanizer Need Shock Absorption:

1. The vulcanizing machine should strengthen the shock absorption measures if it wants to operate normally in production. There are two kinds of measures to strengthen the shock absorption:

• Thickening the pad on the workbench: add a certain thickness of the pad between the vulcanizer table and the lower die to move the working stroke of the moving beam up, thereby reducing the volume of the upper cavity of the working cylinder when the load is suddenly lost. The stored elastic energy of the liquid is reduced.
• Add a movable spacer to the vulcanizer. A movable spacer is added between the piston of the vulcanizer cylinder and the moving beam, so that the volume of the upper chamber of the working cylinder is reduced when the material is broken, and the stored elastic energy is also reduced accordingly.

2. The three sealing materials commonly used in vulcanizers are polyurethane rubber, oil resistant rubber and polytetrafluoroethylene.

• Polyurethane rubber is a new type of rubber material widely used in various hydraulic cylinders. It has excellent physical properties and chemical stability, and has good strength, elasticity and oil resistance. It also has excellent wear resistance. Sex. Can withstand high pressure.
• oil-resistant rubber and cloth rubber: the most used nitrile rubber, has good elasticity
• Polytetrafluoroethylene (plastic): The biggest feature is high heat resistance and good corrosion resistance.

Heating Plates Main Features:

Flat vulcanizing machine is used in many enterprises. Its main feature is to provide pressure and temperature. This temperature comes from the heating plate, which can be divided into the following aspects.

1. The upper and lower heating plates of the vulcanizer are small in size and light in weight, with low energy consumption and fast heating. After heating, the whole plate has considerable flexibility. It is tighter than the conventional machine. Under 1.5mpa pressure, it is parallel. The tightness is not more than 0.03mm, and the conventional machine does not have this performance.
2. The upper and lower heating plates of the vulcanizer supply heat evenly. After entering the heat preservation stage for 10 minutes, the temperature difference between the working faces is only ±3 °C ~ 4 °C, which exceeds the international standard.
3. The time from normal temperature to vulcanization temperature (145 °C) is no more than 25 minutes, the power is half lower than that of the same industry at home and abroad, and the energy saving effect is good.
4. Vulcanized glue or repair once formed, the bonding site is smooth, smooth, and the fastness is no different from the original tape.
5. The upper and lower heating plates of the vulcanizer are three-in-one, and the structure is simple and easy to install.

The five advantages of the flat vulcanizing machine and the upper and lower heating plates of the vulcanizer are unmatched by other machines.

Vaulcanizing Machine Normal problems:

1.  When heating, the temperature of the heating plate is not uniform, causing the joint parts to be intimately bonded. The following steps should be checked.

• Check whether the insulation board is damaged or not, and the insulation board is damaged, which causes an uneven heating temperature.
•  If the insulation board is intact, the heating plate can be heated separately, and then the thermometer is used to carry out the heating plate. If there is a problem, the internal heating piece may be damaged. Contact the manufacturer to provide the heating piece for replacement. Return to factory maintenance

2. Due to improper storage or bumping during use, water seepage phenomenon occurs, should follow the following steps to check

• Check the water seepage part, whether it is the contact surface of the water pressure plate surface or the surrounding rubber sheet and the lower plate of the water pressure plate. If the gap around the water plate is leaking, the surrounding screws should be tightened in order.
• If the water leakage part is the surface of the water pressure plate rubber, the water leakage part is needle-shaped. In the case of repair, the 520 glue can be used for repair, but the panel replacement must be performed after the repair.
• In case of serious water leakage, it cannot be used and the water pressure plate must be replaced.

3. The phenomenon that the adhesive tape is bonded to the heating plate after the vulcanization is completed by individual users. The reason for this problem is that the user does not have a spacer such as newspaper or talcum powder in the middle of the upper and lower heating plates in accordance with the operation requirements. The heating plate is in direct contact with the conveyor belt. After this problem occurs, it is only necessary to clean the heating plate. In the next use, it will not appear again in strict accordance with the operating procedures.
4. When using the manual pump to press, there is a phenomenon that the pressure does not go up. You can check it by the following steps.

• Check if the water inlet of the water pressure plate is pressed due to the tightening of the frame bolts. If this happens, loosen the bolts properly.
• Check the hand pump for air leaks or loose joints and tighten them, and check the gasket of the hydraulic pump for damage.

5. The heating process becomes longer or the temperature cannot reach 145 °C. If the above problems are encountered, the following steps should be checked.
