Operation steps of flat 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 base. When the amount of oil is insufficient, it should be added in time. The oil must be finely filtered before injection. Add pure 20# hydraulic oil into the oil injection hole of the lower machine base. The oil level can be seen through the oil gauge, and it is generally added to the height of 2/3 of the lower machine base.



(2) Check the lubrication between the column shaft and the guide frame and add oil in time to maintain a good lubrication operation.



(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 from the oil pump enters the oil cylinder, and drives the plunger to rise. When the hot plate is closed, the oil pump continues to supply oil , When the oil pressure rises to the rated value (14.5MPa), press the registration stop button, so that the machine is in the state of stopping and maintaining pressure (that is, timing vulcanization), and when the vulcanization time is reached, move the handle to lower the plunger to open the mold.



(4) Temperature control of the hot plate: Turn on the rotary button SA1, the plate will start heating, and when the temperature of the plate reaches the preset value, the heating will stop automatically. When the temperature is lower than the set value, the plate is automatically heated to keep the temperature at the set value.



(5) Control of vulcanizing machine action: Press the motor start button SB2, the AC contactor is powered on, and the oil pump works. When the hydraulic pressure reaches the set value, the AC contactor is disconnected, and the vulcanization time will be automatically recorded. When the pressure drops, the oil pump motor starts. Automatic pressure supplement, when the set vulcanization time is reached, the buzzer will sound to inform that the vulcanization time has come, and the mold can be opened, press the sound stop button, move the manual operation valve, and make the plate drop, and the next cycle can be carried out.
