Operation Technology Of Embossing Machine

1、 Preparation:

1 Check the hydraulic oil quantity before use, Hydraulic oil The height is 2/3 of the height of the lower base. If the oil is insufficient, it should be added in time. The oil must be carefully filtered before injection. Add pure 20 # hydraulic oil into the oil filling hole of the lower engine base. The oil level is generally 2/3 of the height of the lower engine base.

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

3 Switch on the power supply, 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 drive the plunger to rise. When the hot plate is closed, the oil pump continues to supply oil, so that 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 shutdown and pressure maintenance (i.e. timing vulcanization), and when the vulcanization time is reached, Move the handle to lower the plunger and open the mold.

4 Temperature control of hot plate: close the rotary button SA1, and the plate starts heating. 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 will be heated automatically 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 starts to be recorded automatically. When the pressure drops, the oil pump motor starts to automatically supplement the pressure, and the set vulcanization time is reached, the buzzer sounds, informing that the vulcanization time has arrived, and the mold can be opened. Press the stop button, Move the manual operation valve to lower the plate for the next cycle.

2、 Hydraulic system

1. The hydraulic oil shall be 20 # mechanical oil or 32 # hydraulic oil, which must be carefully filtered before being added.

2 Drain the oil regularly, filter it before use, and clean the oil filter at the same time.

3 All parts of the machine shall be kept clean, and the column shaft and guide frame shall be oiled frequently to maintain good lubrication.

4 In case of abnormal noise, stop the machine immediately for inspection, and continue after troubleshooting use 。

3、 Electrical system

1 The host and control box should be reliably grounded

2 All contacts must be clamped and checked regularly for looseness.

3 Keep the electrical components and meters clean, and do not hit or knock them.

4 Stop the machine for maintenance immediately in case of any fault.

matters needing attention

The operating pressure shall not exceed the rated pressure (14.5MPa).

The minimum dimension of the mold should be greater than φ 150mm。

The main power supply shall be cut off when it is out of use.

During operation, the column nuts must be kept tight and checked regularly for looseness.

During empty car test, 60mm thick Base plate 。
