Operating Procedures for Plate Vulcanizing Press
Release time
Nov 22,2021
In rubber processing, the press is called a flat vulcanizing machine. The main parameters of the press include nominal tonnage, press size, working stroke and plunger diameter. These indicators determine the area, height or thickness of the product that the press can press, and the maximum stamping pressure that can be achieved. According to its structural characteristics, the mold is divided into three types: overflow type, underflow type and semi-overflow type. Among them, semi-overflow type is used a lot. Then, let's learn about the operating procedures of the lower flat vulcanizing machine!
Operating rules of plate vulcanizing machine
1. preparation:
1. Check the amount of hydraulic oil before use. The height of the hydraulic oil is 2/3 of the height of the lower machine. When the amount of oil is insufficient, it should be added immediately and carefully filtered before injecting the oil. Add pure 20# hydraulic oil to the oil filling hole of the lower machine table. The height of the oil level can be seen from the oil level index, which is generally 2/3 of the height of the lower machine table.
2. In order to maintain good lubrication, check the lubrication between the column shaft and the guide frame, and add oil in time.
3. Turn on the power, move the operating handle to the vertical position, close the oil return port, press the motor start button, the oil discharged from the oil pump will enter the cylinder, and the plunger will rise. After the heating plate is closed, the oil pump continues to supply oil. When the hydraulic pressure rises to the rated value (14.5MPa), press the registration stop button to make the machine in a state of stopping and maintaining pressure (that is, timing vulcanization). When the vulcanization time is reached, the handle is driven to make The plunger drops
4. Temperature control of the heating plate: Place the molding mold on the heating plate, turn off the rotating button SA1, and start heating the plate. When the temperature of the plate reaches the preset vulcanization temperature, the heating will automatically stop. When the temperature is lower than the set value, the baking plate is automatically heated, and the temperature is always kept at the set value.
5. Control of vulcanizer work: press the motor start button SB2, the oil pump works, the mold is closed and pressurized, after the oil pressure reaches the set value for a few seconds, release it 1~2 times, overflow air and volatile gas, press the rear gold mold, start the automatic recording of vulcanization time, pressure drop, oil
2. plate vulcanizing machine hydraulic system
1. Hydraulic oil should use 20# machine oil or 32# hydraulic oil. Hydraulic oil should be carefully filtered before adding.
2. Regularly discharge the oil, use it after precipitation and filtration, and clean the oil filter at the same time.
3. All parts of the machine should be kept clean, and oil should be added frequently between the column shaft and the guide frame to maintain good lubrication.
4. When abnormal noise is found, immediately stop the inspection and continue to use after troubleshooting.
3. the use of flat vulcanizing machine precautions.
1. The operating pressure shall not exceed the rated pressure.
2. The small size of the die should not be smaller than the diameter of the plunger. The mold should be placed in the middle of the heating plate; the pressure of the working fluid should be adjusted according to the size of the mold and the vulcanization time.
3. When you stop using it, cut off the main power supply.
4. During operation, the column nut shall be kept in a tight state and checked regularly for looseness.
5. When the test machine is empty, a plate with a thickness of 60mm needs to be placed in the flat plate.
6. Host and control box need reliable grounding
7. Each contact shall be clamped and checked regularly for looseness.
8. Keep the instruments of electrical equipment clean and do not bump or knock the instruments.
9. If a fault is found, the inspection should be stopped immediately.
4. tape flat vulcanizing machine use precautions.
1. Before the heating plate is closed, it is necessary to check whether the shim iron and the stop overlap. Do not place tools, irons, or other foreign objects on the cloth to avoid damaging the clamping plate or hot plate during clamping or vulcanization.
2. The roll spacing at both ends of the traction tractor should be the same to avoid excessive roll spacing and prevent the tooth tops of the transmission gears. When the wire and connector of the tape pass, please lift the roller appropriately to avoid damage to the workpiece.
3. After the conveyor belt is vulcanized, if it is stuck to the heating plate, use a wooden stick to separate the conveyor belt from the heating plate, and cannot be directly pulled apart by a tractor.
4. When the heating plate is raised and lowered, the balance of the heating plate is maintained.
5. When using the decontamination machine, please wear protective glasses to avoid damage to your eyes.
5. with v-type jaw plate vulcanizing machine use precautions.
1. The maximum working pressure of the hydraulic system shall not exceed the rated value.
2. V-belts to the short circumference and to the large circumference specified in the specification are vulcanized.
3. When an abnormality is found, stop the inspection and continue to run after troubleshooting.
4. Please ground the electrical box.
5. The machine should be used in accordance with the safe operation of the equipment.
6. Do not place garbage on the host tank.
The above is the flat vulcanizing machine operating procedures, if you need to know more, you can contact us at any time!
