What Is Bar Bending?
Rebar bending machine, one of the steel processing machinery. The working mechanism is a horizontal working disc that rotates on a vertical axis. The steel bar is placed in the dotted line in the figure. The support pin is fixed on the machine tool. The center pin and the bending pin are mounted on the working disc. The disc rotates. When you bend the rebar. In order to bend steel bars of various diameters, there are several holes in the working plate for inserting bending pin shafts, and central pin shafts of different diameters can also be replaced accordingly.
- Rebar
- First, check whether the mechanical performance is good, the table and the bending machine table are kept horizontal; and various mandrel tool stops are prepared.
- 2. Install the mandrel, forming shaft, iron shaft or variable bracket according to the diameter of the processed steel bar and the requirements of the bending machine. The diameter of the mandrel should be 2.5 times the diameter of the steel bar.
- Third, check the mandrel, stoppers, turntables should not be damaged and

- Rebar bending machine use: It is suitable for the construction of various common carbon steel, rebar, etc. into various geometric shapes required for engineering. GW40 steel bar bending machine, because of its simple structure, reliable work and sensitive operation, can bend 6-40 mm or 6-50 mm steel bars into various shapes required in bridges and construction projects. Prefabrication plant and construction site operators welcome.

- 1. Take a length of 200-250mm from the metal wire to be inspected and straighten it. Do not damage the surface of the wire when straightening.
- 2. Select the arc radius r of the clip according to the diameter of the wire in the parameter table, the distance b from the top of the clip arc to the bottom surface of the lever, and the hole of the lever. Each radius is printed on the clip for selection. The distance b is obtained by adjusting the position of the lever through the three holes on the rocker arm. The holes 35, 50, and 75 in the following order can be identified by the numbers printed around the holes on the lever.
- 3. There are four holes on the main lever that are perpendicular to each other. Adjust the direction of the lever to get the hole position you need. When using a hole with a threaded end, the shaft sleeve should be sleeved. Remove the sleeve to ensure that the wire is on the centerline of the bend.
- 4. Place the rocker arm in the vertical position, and use this as the initial state of the test. First insert the sample into the hole in the bottom plate of the two clamps, and then vertically go through the hole of the lever from the lower part of the lever and then pass in. From the upper clamp to the top, turn the upper chuck handle to clamp the upper end of the wire.
- 5. Press the upper chuck down by 15-25mm with your hand and stabilize it (the distance of the thick wire should make the wire have a tightening force of about 15-25 kg). Turn the main clamp handle to clamp the lower end to bend.
- 6. When bending the specimen, a more uniform speed (about 1 time / second) should be used.
- 7. The bending count is 90 ° to the right from the starting position, the specimen returns to the starting position for the first time, and then bends to the left 90 °, and the specimen returns to the starting position for the second time. And so on until the specimen breaks, the last bending of the specimen is not counted.
- 8. After long-term use, the arc surface of the clip should be replaced if there are signs of crushing.
- 9. The oil cup and the place where there is relative sliding should be refilled frequently to keep it lubricated.
- 10. Wipe clean after use and apply anti-rust oil to prevent rust.
- 11. Installation: The machine should be installed on the edge of the workbench, and the rotating handle should be extended outside the workbench. The mounting screws are three M8 screws. There is a 10 hole in the bottom plate of the two clamps. The workbench should also be drilled. Exit the hole to allow the wire to pass freely in the hole. [3]
