How is the rubber continuous vulcanization line operated?

In the processing of rubber continuous vulcanization production line, the press is called a flat vulcanizer. The main parameters of the press are nominal tonnage, platen size, working stroke and plunger diameter, which determine the area, height or thickness of the product that the press can form and the large forming pressure that can be achieved. According to the structural characteristics of the tool, it can be divided into three types: overflow, overflow and semi-overflow, of which semi-overflow is commonly used. The processing process is divided into household materials, sealing tools, exhaust, hardening, lint, tool cleaning, etc. For products that require sealing inserts during the molding process, the inserts should be placed before filling. The main control process conditions are pressure, molding temperature and intermediate molding process. Molding is also a very important molding method in the rubber industry. Cut or cut the rubber into simple shapes, put it in a heating tool, vulcanize during the molding process, and the product will shed hair during the hot process. Many rubber model products (such as gaskets, shock-absorbing products (such as aprons, rubber plates) are produced in this way.

The operation specifications of rubber continuous vulcanization production line are as follows:

1. preparation:

1. Check the oil pressure flow before use. The height of the hydraulic oil is 2/3 of the height of the Hart block. Wait in the process of insufficient traffic, add in the process. Milk should be carefully filtered before injection. Fill the filling hole of the lower seat with pure 20# hydraulic oil. The flow height can be seen through the flow table, usually adding to the 2/3 of the height of the lower seat.

2. Check the lubrication between the drive shaft and the guide frame, and add oil in the process to maintain good lubrication.

3. Turn on the power, move the working handle to the vertical position, close the oil return port, press the motor start button, the oil produced by the oil pump will enter the oil barrel and drive the plunger to rise. After the hot plate is turned off, the oil pump will continue to supply oil. When the oil pressure rises to the rated pressure (14.5MPa), press the stop registration button to stop the machine compression (ie

4. Hot plate temperature adjustment: Put the mold on the hot plate, close the knob SA1, and the hot plate starts to heat. When the temperature of the plate reaches the preset vulcanization temperature, the plate will automatically stop heating. When the air temperature is lower than the set value, the plate will be automatically heated, so that the air temperature is always maintained at the set value.

5. Curing machine action control: motor start button SB2, oil pump operation, clamping pressure and oil pressure to reach the adjustment value, loosen 1~2 times, and then tighten the tool, automatically record the middle of the vulcanization process. When the pump motor starts to automatically compensate for the pressure drop, it reaches the intermediate setting during the curing process.

Hydraulic system of 2. rubber continuous vulcanization production line

1. Hydraulic oil must use No. 20 oil or No. 32 oil, which must be added after fine filtration.

2. regular oil, sediment filter after use. Clean the oil filter in the same process.

3. All parts of the machine should be kept clean, and oil should be added frequently between the pillar shaft and the guide rail to maintain good lubrication. 4. If abnormal noise is found, please shut down immediately for inspection and solve the problem before continuing to use.

Precautions during the use of 3. rubber continuous vulcanization production line.

1. The working pressure can not exceed the rated pressure.

2. The small size of the tool should not be smaller than the diameter of the plunger. The tool should be placed in the center of the hot plate. The working hydraulic pressure should be adjusted according to the size of the tool and the vulcanization process.

3. In the process of stopping use, be sure to cut off the main power supply.

4. During the operation, the column nut should be kept tightened and checked regularly for looseness.

5. In the process of empty vehicle debugging, a 60mm thick backing plate must be placed in the flat plate.

6. The host and control box must have reliable grounding.

7. Be sure to tighten it every time you touch it and check it regularly for looseness.

8. Keep the instruments in the electrical part clean, and all instruments shall not collide or knock.

9. If a fault is found, stop maintenance immediately.
