Silent Steel Bar Bending Machine TW42

SILENT STEEL BAR BENDING MACHINE TW42

1. We choose industry gear box and whole sealed, so this kind of gear box like car gear box, the noise only has 10-20 dB and compare normal bending machine the dB is more than 60-80 dB(check the video of TW40 in attachment to bend 32mm bar);

2.The whole life of this kind of bending machine is no need change gear oil because whole sealed, that means you can save twice change oil cost every year compare normal bending machine, and this can save around 100USD per year, if ten years, you can save 1000USD totally.

3. Good warranty promise, the gear box we will give ten years warranty, if any broken we will replace for free.

4. Economic price, same capacity model is just 10% up price.

So this machine will change and replace all other bending machine design in coming future, and bending machine is going to silent working time.

We have three models:TW42,TW40 and TW22.Today I'd like to introduce TW42.

Technical parameter:

Structural Features:

TW42 steel bar bender consists of drive mechanism, framework and workbench，drive mechanism is through reduction motor drive working disc.and TW42 also have angle adjustment structure,angle adjustment device on the working disc,can achieve semi-automatic operation.TW42 have simple structure,less noise and easy operation.

Installation and Operation:

1 Steel bar bending machine TW42 bends 6-42 mm. steel bar into various shapes according to the needs of building works by employing pile head casing, guide pile head, striker plate, etc. In the following figure, TW42 is given as an example to detail the installation method of work pieces.

2 Following aspects shall be noted for bending steel bars of different diameters: bending radius shall be determined according to the rebar diameters and ultimate tensile strength, which means that suitable pile head casing, striker plate, etc. must be used. If example is given for Class I deformed steel bar as per 2.5 times of the steel bar diameter, recommended pile head casing or guide pile head is listed for rebar of different diameters. Please refer to Table I for the relationship.

Table I  Class I steel Q235 (σb≤450N/mm²)    unit: mm

Note: σb refers to the ultimate tensile strength (stress) of steel bar

                 Table II  Class II steel C45 (σb≤650N/mm²)    unit: mm

Note: σb refers to the ultimate tensile strength (stress) of steel bar

3 According to respective tensile strength, pile head casing or guide pile head shall be selected based on Table III and installed at the center of the working disk. Suitable guide pile head and pile head casing shall be mounted on the working dick and striker pile head and striker plate shall be mounted on the guide square steel. Then, empty run can be carried out. If no failure occurs, bending can be carried out.

4 According to the difference of diameters and strength, the maximum quantity of rebar to be bended at the same time is given below in Table III.

A. the event of failure, bending shall be stopped immediately and continued after the failure is fixed.

B. To reduce the time of measurement, gauge may be set on the workbench to show the installation position of rebar before shape up.

Details:

1. Foot pedal and manual control free switch,convenient and practical.
   

2. Forged square steel,discs,special heat treat pile head accessories.

3. Silent gearbox,life-long refueling free.
