Gw42D Steel Bar Bender/Automatic Steel Bar Bender

 GW42D steel bar bender


I Amplification and advantages:
GW42D steel bar bender are reinforced bending equipments used in construction site which are researched and developed by our company. These models have the following advantages:
Integral enclosed housing which assures the moment distribution is reasonable, no local deformation phenomenon; extra strong and aggravating housing assures increased strength. Gear shaft and main spindle are made of high quality carbon steel materials; the important parts are of high standards of heat treatment.The main spindle is supported with ball bearing of high bearing capacity, handy movement and long service life, parts and components under high load conditions also have long-term safe operation.Square steel and working plate is made of high quality carbon steel, pile head and pile tip using alloy steel with high hardness heat treatment ensures long-term reliable use.Brake motor, Adjustable square steel and Bolt type positioning disc Make disc self-return, Angle adjustment is convenient, and bending angle is accurate.
After adding enough lubricating oil before using, there is no need to refuel the lubricating oil constantly in the spindle sliding sleeve like ordinary bending machine; it is convenient operation and maintenance.Bending mode is manual/automatic switching with brake motor.
II Main technical parameters:
Model: GW42D
Bending diameter: Φ 6 - Φ 40 (Ub plain round bar <= 450 mpa)
Φ 6 - Φ 36 (level II deformed steel bar)
Work disc diameter: 360 mm
Motor power: 3 kw - 4p
Spindle speed: high speed 10r/min and low speed 7r/min
Weight: 340 kg
Overall dimension: 910 * 730 * 810




III Preparation before operating:
3.1. Check
(1). The outer packing is damaged or not, whether there are damaged parts that can affect the normal use
(2). check if all nut, bolt and screw are reliable fastness.
3.2. Installation
(1). before install machine
A choose smooth and strong ground, machine keeps horizontal position.
B leave enough space to pile up raw materials.
C leave enough space of convenient transportation finished site.
D access power supply voltage must be in standard voltage + 10% range, and reliable grounding.
(2). After moving machine to work site and accessing power supply, and then do the debugging.
(3). put foot switch plug into the socket of the electric door.

3.3. Lubrication
Open the table top fuel cap, add No. CKC68 gear oil to two-thirds level of the oil window (or 10 kg).

V. Debugging
4.1. After finishing the above steps, connect the line supply. Perform pre-commissioning when the power light indicates the power is on.
   (1)Turn on the OPEN CIRCUIT, MOTOR FORWARD AND REVERSE BUTTON, the power would be connected.
   (2)Click the START button, the motor would spindle forward. If not, please pull the OPEN CIRCUIT, MOTOR FORWARD AND REVERSE BUTTON to the other side to change the motor spindle direction.
   (3)Pull the MANUAL/AUTO BUTTON to AUTO, insert the angle positioning pin into the holes in the working disc. Step on the foot paddle, the motor would start and working disc turn. When the angle positioning pin reaches the position of REVERSE POSITION SWITCH, the motor would reverse. If the motor do not reverse, please check the circuits and if the angle positioning pin touches the REVERSE POSITION SWITCH.
   (4)ANGLE TRANSFORMATION SWITCH can make two different angle alternative. For example, first turn the ANGLE POSITIONING PIN to 90 and bend the steel to 90 degrees, then turn the ANGLE TRANSFORMATION SWITCH. After that, step on the foot paddle, and the machine would bend 135 degrees.
   (5)Pull the MANUAL/AUTO BUTTON to MANUAL, press on the START, FORWARD button or MANUAL REVERSE button, the machine would work continuously. If just click the button, the machine would only work off and on.
2. Load debugging
(1). Choose the suitable center pile head, pile head and sleeve according to the size of steel. The positioning pile head, keep-off pile head and striker plate should be placed according to the bending direction.
(2)For different size of steel, the bending radius is according to the diameter and tensile ultimate strength of steel.
(3)Put the steel on the working disc, adjust the striker plate and make it appress the steel. Adjust the square bar and make it appress to the center pile head. For security, insert a keep-off pile head beside the square bar.
(4)There should be at least two people cooperate to do the bending work for long bar.
(5)The working radius area and non-pile head side of the machine should be no people.
(6) Press the START FORWARD button, the working disc would turn and perform bending work. (For automatic bending machine, please do insert the ANGLE POSITIONING PIN, or the machine would work continuously and cause accident.)
(7)When multifunction, stop the machine instantly and restart working after accident is cleared.
(8)Non-straight steel are prohibited to bend by this machine to avoid accident.

VI Maintenance
1. Change the lubricating oil 3 months later after using the new machine. Change the oil every year thereafter. Oil changing should better happen during heat engine state.
How to change oil:
Twist off the oil drain screw which is under the quasi reducer. Discharge the waste oil and restart the engine to let out the residual waste oil. Then tighten the screw and fill in new gear oil.
2. Choose the suitable pile head and sleeve according to the strength and diameter of bar. Small sized positioning pile head is prohibited to bend big diameter steel.
3. Clean up the working disc every shift and daub lubricating grease. Oil filling and daubing are prohibited while the machine is working.
4. Don't change the center pile head, keep-off pile head or striker plate.
5. Daub anti-corrosive grease to the working disc and keep the machine in dry place for long term storage.

Marking Unit: 

This unit is consists of fixed lathe bed, movable lathe bed, hydraulic pressure head and manual adjustment device. According to the order of computer, the unit marks on places required on the drawings. For making the marks clear and endurable, and avoiding the angle steel abrades character heads, it adds the functions of loading oil cylinder and lifting movable lathe bed. For satisfying the processing scope, it adds manual adjustment device, which can change the position of characters to adapt different standards angle steel.

Workpiece Table: It is driven by engine and retarder through chain wheel and chain. There are three long axis and six self-control shaft couplings to achieve synchronization of the chains. Thus the angle steel will be stable and make lower noise during feeding process. The function of this part is that feed angle steel into the chute and prepare to be taken by the clamp device.

 

Overturning Rack: It is driven by engine and retarder through chain wheel and chain. Thus it achieves synchronization of swivel arm of the four clamps devices through long axis and shaft couplings. The function of this part is to take angle from conveyor trough to feeding conveyor.
