Machine Installation And Debugging And Operation

Machine installation, debugging and operation

• Before the whole machine is installed, the following should be done:
1) Before installation and use, check that the whole machine parts and electrical appliances are complete and whether there are screws loose or damaged during transportation and handling;
2) The surface of the machine should be leveled to prevent vibration during operation and damage the components or electrical appliances.

• Before installing the entire machine, the following should be done:
1) Before installation and use, check whether all machine parts and electrical appliances are complete, whether there are loose screws or damage during transportation and handling.
2) The surface of the machine should be leveled to prevent vibration during operation and damage to components or electrical appliances.

• Turn on the power
1) After careful inspection, connect the power source to the power terminal.
2) Turn on the controller power switch.
Note: The machine should be placed on the ground smoothly. The power cable should be used within 50 meters with a minimum of 6 square millimeters of national standard copper cable and a leakage protection switch.

• Turn on the device.
1) After careful checking, connect the power supply to the terminals.
2) Turn on the power switch of the controller.
Note: The machine should be placed on a flat floor. The power cord should be within 50 meters with a national standard copper wire of at least 6 square millimeters and a leakage protection switch.

• No-load test machine
1) Turn on the power to turn on the controller power switch, you should see a normal digital display on the controller. If you do not see the normal digital display, please check if the power supply is out of phase and whether the voltage is normal or not, etc.
2) After correct operation, follow the “Operation Step 3 Angle Setting Operation” setting – an arbitrary angle (between 5 and 200°), step on the foot switch, check the motor's steering, such as reverse (the controller has no normal digital display) Please change the thread head; the motor rotates clockwise during operation and rotates counterclockwise when retracting.

• No-load tester
1) Turn on the power to switch on the controller power, you will see the normal digital display on the controller. If you can't see the normal digital display, please check if the power supply is out of phase and the voltage is normal, etc.
2) After the correct operation, follow the setting of “Step 3 Angle Setting” – arbitrary angle (between 5 and 200 °), step on the foot switch, check the motor steering, such as reversing (the controller does not have a normal digital display), the motor will rotate clockwise during operation, and rotate counterclockwise when reversing.

• Load test machine
1) Preparation before the test machine: Select and install the bending die (inner wheel, shape guide strip, etc.) according to the diameter and curvature of the curved steel pipe, and adjust the pinch device (internal pinch die) to the appropriate position.
2) Fixed length and tightened steel pipe: adjust the fixed length device according to the length of the steel pipe to be bent and clamp the steel pipe;
3) Angle setting: According to the “Control Panel Easy Description”, set the angle.
4) Bent steel pipe: foot pedal switch, one step at a time, each time bending one angle, then loosen the clamping device; repeat the “operation step 2) fixed length and tighten the steel pipe” bent steel pipe, take out after completion Steel Pipe.
5) Angle correction; When there is an error in one or several angles and the actual angle during the bending work, the angle correction can be performed according to the “simple description of the control panel”.
6) Repeat “Operation Step 2) Fixed Length and Tightening Steel Pipe and Operation Step 4) Bending Steel Pipe”, and re-run the machine so that mass production can be carried out.

• Load test machine
1) Preparation before testing machine: Select and install the bending die (inner wheel, shape guide bar, etc.) according to the diameter and curvature of the bent steel pipe, and adjust the squeezing device (inner pinch mold) to the appropriate position.
2) Fixed length and steel pipe tightening: Adjust the fixed length device according to the length of the steel pipe to be bent and tighten the steel pipe.
3) Angle setting: According to “Simple Description Control Panel”, set the angle.
4) Steel Pipe Bend: Step foot switch every time you bend one angle, then loosen the clamping device, repeat “Operation step 2)Fixed length and tighten steel pipe”, the steel pipe bend is taken out after completion of Steel Pipe.
5) Angle correction: When an error occurs in one or more angles and the actual angle during bending, angle correction can be performed according to the “Simple Description of the Control Panel”.
6) Repeat: “Operation step 2) Fixed length and tightening of steel pipe and operation step 4) Bending of steel pipe” and run the machine again to achieve mass production.
