4 Kind Rebar Straightening Machine: How To Use

rebar

When massed as reinforcing steel or reinforcement steel, rebar (short for reinforcing bar) is a steel bar or mesh of steel wires used as a tension device in reinforced concrete and reinforced masonry constructions to strengthen and assist the concrete under tension.

Concrete has high compressive strength but low tensile strength. Rebar greatly improves the structure’s tensile strength. In this article, we have discussed, how to straighten rebars with 4 different kinds of machines.

Before we discuss the rebar straightening machine, let’s discuss some basic parts of the rebar straightening machine.

1.1     The rebar straightening machine’s rerouting section

It can perform automated pay-off without the need of a hoist, and it should be placed about 6-8 meters distant from the front end of the rebar straightening machine to guarantee enough tension and length excess throughout the operation.

1.2     The rebar straightening machine’s pre-adjustment section

To finish the stress relief processing of the rebars supplied from the material rack and remove surface rust, rely mostly on 5 sets of vertical straightening wheels. Wire guide sleeve devices are used on the components, and they are usually pre-adjusted for tightness and stress alleviation.

1.3     The rebar straightening machine’s straightening barrel.

The straightness of the rebar may be altered at a whim by using the straightening wheel to support the left and right wires to move forward and backward, primarily by removing stress and advancing the operation of the rebar.

1.4     The rebar straightening machine’s traction and feeding system

There is a single pair of active and passive feeding boxes, which are assembled behind the active box’s turbine shaft to drive the passive box’s sprocket and chain, consequently driving the passive box behind to complete the full feeding operation before and after straightening.

Rebar Straightener (Rotate Straightening)

It is a piece of construction equipment that is used to straighten steel bars or scrap rebar, as well as recycle scrap rebar. It can immediately shred rebar sizes ranging from 5mm to 12mm at a pace of 20m per minute, thanks to a powerful 5.5Kw engine (depending on rebar diameter).

How to use it

One operator is all that’s required. Use the machine by following these procedures.

  1. Bring in scrap rebar in traction input gear. The machine can handle scrap rebar without assistance. Straightening roller bolts should be adjusted, straightening rollers should be level and clean, and the rebar should be touched attentively.
  2. It has a cutting facility that really can cut the head off a bent bar; if inserting a twisted bar into the hole is problematic, use the cutting facility to cut the twisted bar head off.
  3. Straighten rebar are exported from traction gearing output
  4. There is the oil hole cover near the gear. It is important to input 5kgs of machine oil before starting the machine.
  5. Straightening frames and rollers are used to straighten scrap rebar. They will roll at a high speed while in operation. It is powered by an electric motor with a transmission chain.

Rebar Straightener (Opposite Roller)

It is a piece of construction equipment that is used to straighten steel bars or scrap rebar, as well as recycle scrap rebar. It can directly shred rebar sizes ranging from 16mm to 25mm at a pace of 20m per minute.

How to use it

One operator is all that’s required. Use the machine by following these procedures.

  1. Add 25kgs of machine oil to the square cover of the reduction gears and inject 25kgs of machine oil to keep the gears lubricated before using the machine.
  2. Import iron bar is utilized with holes ranging from 10mm to 25mm in diameter. It includes a variety of holes to handle various diameters of iron bars. It is driven by a powerful reduction gearbox capable of drawing and straightening a 25mm iron bar.
  3. Straightened rebar will be released via the output hole.

Rebar Straightening And Cutting Machine (Horizontal Type)

It is a CNC-powered machine that can work greatly with rebars of larger lengths. The machine is an expensive alternative to the previous two machines. However, it brings in the capability of speed and automation.

 How to use it

One operator is all that’s required. Use the machine by following these procedures.

  1. The lubrication applicator feeds the rebar through, coating it in an even layer of lubricant.
  2. The lubricated rebar is next carried through the profile section, where a roller belt reduces the diameter of the rebar while increasing its tensile strength.
  3. The rebar is then rolled via profiling rollers, which also apply the reinforcing profile to the rebar. The rod is straightened after profiling by running it through the spinner or rollers.
  4. After that, the rebar is profiled and straightened before being cut to length using a flying shear and discharged into the runout and receiving trays.

Rebar Straightening Cutting Machine (Vertical Type)

Rebar straightening and cutting machines are meant to be stand-alone lines for high-speed manufacturing of straightened and cut rebar. These machines are well-built and come with a variety of payout choices (DIN or Motorised Rotating Platforms) to accommodate the rebar’s presentation.

How to use it

One operator is all that’s required. Use the machine by following these procedures.

  1. A set of feed wheels feed the rebar through the twin rotor assembly before it is chopped to length in a high powered shear. The feed and spinner drives are gear boxed to assure that the straightening angle stays consistent under all conditions, resulting in outstanding rebar straightness.
  2. The cutting length is programmed directly into the CNC panel, which is driven by a microprocessor, resulting in the exact length of produced components.
  3. Straightened and chopped rebars leave the runout and are dumped in little bundles from the straightener.
  4. Hydraulics are used to power the machine.
