6、 Operating instructions:

Explanation of Four Modes of Work

◇ "Manual" working mode operation (the initial working mode is "manual" when powered on):

After pressing the "Run" button, enter the manual operation screen and follow the on-screen prompts to operate:

1 Pressing the corresponding action key can execute various corresponding actions;

2. When manually bending the pipe, stop bending when the first set angle is reached (convenient for mold testing);

3. Oil cylinders with sensors, regardless of whether the manual button is pressed, will stop operating when the sensor sends a signal;

4. When performing clamping and bending operations, the auxiliary push must be fully retracted (there will be corresponding prompts at the bottom of the screen);

◇ "Semi automatic" working mode operation (recommended for normal production):

1: Manually install the work;

2: Stepping on the pedal switch, the automatic clamping work begins, and the automatic bending begins. After the bending angle is equal to the set angle (if there is a correction value, this value should be subtracted from the correction value), the bending action automatically stops and the core is removed;

3: Step on the foot switch to automatically bend and insert the core;

4: At this point, complete a bend. If the corner count is equal to the set number of corners (the last corner), proceed to step six;

5: Corner counting automatically increments by one

Go to the second step and continue bending the next corner;

6: Add one to the workpiece count, manual removal of the workpiece is complete!

◇ Fully automatic explanation:

Fully automatic only allows for bending without the need for foot pedals after taking out the workpiece during the semi-automatic process.

◇ Test instructions: After setting the mode to test, press the foot pedal to run the machine and keep the program running in a loop.

The test machine can only be used for idle operation of the machine and cannot be used for processing!

7、 Principle Introduction:

No load, power on, press the motor start button, the motor works, the indicator light button lights up, the oil pump works, filtered, draws oil from the oil tank, and returns to the oil tank through the overflow valve

Pinch pipe - bend pipe - clip out - film transfer back - bend out - film transfer in - empty load state

8、 Debugging and mold installation

Fill up the mailbox with fuel

Connect to 380V power supply

Press Start

According to the corresponding actions, various actions can be executed

When manually bending the pipe, stop bending at the first set angle (convenient) for mold testing

Oil cylinders with sensors, regardless of whether the manual key is pressed or not, stop operating when there is a signal from the sensor

When performing clamping and bending operations, the auxiliary push must be retracted (there will be corresponding prompts at the bottom of the screen)

Adjust the overflow valve to make the system pressure appropriate
