KAKA INDUSTRIAL JTB-50 Tube Bending Machine Instruction Manual

About the Product:

This Tube bending machine is a motor-driven tool set for special purposes, can make adjustments to workpiece holdings either mechanically or hydraulically. By utilizing the metal materials’ adaptable distortion, the tool can bend workpieces such as low-carbon and stainless round tubes, square tubes, steel angles, I-shaped steel stripes and round steel bars to achieve your desired shapes. Being indispensable equipment for construction and beautification works today, can be widely used in the field of building construction, decoration industry, furniture building and garden construction.

The equipment features “one-touch” operation on single workpiece and data- program controlled mass processing. Being easy to operate, reasonable in composition, and low power consumption with high work efficiency, the equipment is ideal for bending metal pipes.

• Trial operation is advised. Connect the machine with power supply (the power indicator now lights up), activate the oil pump power supply to turn on the hydraulic oil
• Select Manual or Auto mode, start

Manual Mode

• Turn the knob to
• Place the workpiece into the die groove and fasten it by #20 Pipe
• Press Clamp button to make the sliding block moves to the set point and make sure workpiece be clamped
• Press Forward spot-turn button to make the reversing valve lever rotary forward so that the hydraulic rod and pressing wheel can squeeze the workpiece to the desired degree of
• Press Reverse Spot-turn button to make the reversing valve lever rotary
• Press Loosen button to make the sliding block moves
• Take off

Note: At manual mode, angle setting function is invalid.

3.  Auto Mode

• Turn the knob to
• Place the workpiece into the die groove and fasten it by #20 Pipe
• Set the proper angle want to bend (0-180º).
• Step on the pedal and the machine will perform fastening, arc bending and repositioning automatically. Make sure that the machine works properly by repeating the steps before bending the
• Take off

Ⅴ. Set Counter

PV: Actual bending angle SV: Required bending angle

• The required angle can be defined by the counter. E.g. if the bending angle is required to be 90º, then the counter should be set up to 90º.
• Press the Forward spot-turn button (or step on the foot-pedal) until the desired angle where it’ll stop automatically and the task

The way to set counter:

1. Press “set” for one second, and then setting value SV is

2. now press＜ to set multiple, when you adjust the multiple you want, then the digit is flickering.

3. Press ∨ ∧ adjust the size of the

4. Press “set” for one second again, quit adjust Then setting value SV is stopped flicker. Setting is finished.

Note: 1. if you press “set” for three seconds carelessly into adjusting counter mode; please don’t change the number anyway. Press “set” continuously until SV shows 0000 correctly. Otherwise the counter can’t work normally. Then use the last four steps to set counter.

2. “set” also has the function to back zero.

Lubrication and Maintenance:

• Bearings of all axis must  be lubricated with calcium  grease on 6-month basis.
• Users are advised to check the condition of the electrical devices on regular basis to ensure the soundness of such devices and ground Turn off the machine in the event of occurrence of any trouble or abnormal sound. Disconnect the machine from the power source, find out the trouble and eliminate it timely.
• Clean the machine after work and apply anti-rust oil onto the unpainted parts of the machine, keep it in good
• A good mastery of the operating sequence will avoid wrong
• Pay close attention to any damage caused to the adjustment

Replace it if necessary to avoid personal injuries.
