Hazards and precautions

1. BAR BENDING MACHINE DO’S &DON’T

2. A bending machine is a forming machine
tool .lts purpose is to assemble a bend on a
work piece

Bar bending machine is consist of electric
motor, coupling, circular plate, worm gear drive,
extended shaft.

Electric motor transmits power to gear
box where speed is decreased and torque
is increased

3. How Many Types Of Bar Bending Machine

Portable Rebar Bender

Electric Rebar Bender

Hydraulic Rebar Bender

Automatic Rebar Bender

4. BENDING MECHINE OPERATIONS
DO'S

Before operating the bending machine read
and understand ¡ts manual instructions.

Every new operator should be appropriately
trained before using the machine for the first
time, preferably by an experienced engineer

well-versed in bending machine safety
precautions

Leveled foundation to be ensured
1.5mx1.5mx. X150mm .

This correct placement will prevent
contact with the sheet with the operator,
avoiding injury.

5. BENDING MECHINE OPERATIONS
DO'S

The work surface should be clean and free
of any scrap metal. Paying attention to
where your hands are during operation

File metal burrs properly, and avoid
touching metal edges or cuts, even while
wearing gloves.

The machines should be inspected regularly
before each operation, especially before the
initial startup.

6. BENDING MACHINE OPERATION
DO'S
Before running the machine need to run a
free trial and error for two minutes.

To understand if there is any problem with
the bending machine.

Checking block- help to
avoiding possible
deformations of the rod can
be used with brad up to 20
mm diameter.

7. BENDING MACHINE OPERATION
DO'S

The sheet metal should be placed parallel to
the bending machine before starting operation.
Chair should be body posture oriented.

The bush positioned on the central hole of the
plate corresponds to the curving radius. To use
bar from 15 mm diameter.

It is important that the diameter of the bush is
at three (3) times bigger compared to the
diameter of the rod to be bent.

Three bush holding pins in special hardened
and cemented steel to be positioned on the
work top together with bushes ,with the
function to support the effort coming from the
phase of bending

8. Number Rebar Bending Chart

Specification Mechanical Bending NBM 40

Diameter of 25 20 16 12) 10
Bars in MM

No of round
bars of
45kg/mm ?

No of TMT bars
of 65kg/ mm ?

9. BENDING MACHINE OPERATION
DON’T

Do not operate the machine if
emergency switch is not working

The purpose of an emergency push button is
to stop the machinery quickly when
there is a risk of injury or the workflow
requires stopping

Do not Leave the any loose
material on the bending table
when machine is not use.

10. BENDING MACHINE OPERATION
DON’T

Do not Stand in the direction
of Rebar Rotation

Do not Bend more than
capacity of machine.

11. BENDING MACHINE OPERATION
DON’T

4 | ME ,

Do not Operate
the machine with

12. Safety for Bender’s

Understand the Manufacturer's safety tips

All rebar benders come with a manufacturer user manual.
A diagram featuring all functional parts of the tool

13. Be careful about your hands and fingers

keep hands away from the pivot shoe, cutting blocks, and rollers while
operating. Last, do not overreach. Keep proper footing and balance at all times.
Warm up the machine before Use It

it creates less stress on the moving parts and allows it to perform its job

safely without added stress to the part.

Place the Bar Properly on the Bender Platform

Select the correct bending angle before you place the bar on the platform.
Incorrect placement can cause the bar to project at the wrong angle and
strike you.

Correct Personal Protective Equipment

«Dust mask

«Shatterproof glasses or goggles

«Non-skid safety shoes

«Hard hat

Hearing.

«Form-fitting, comfortable clothing that is not loose
*Glove
