GeneralRebar straightening machineThe distance between the fixed blade and the moving blade is 0.5~1mm. Two stops are installed on the machine base on both sides of the knife edge to reduce the swing. The design of this machine is reasonable, and the coefficient is increased under the condition of increasing the speed, which solves the accidental injury caused by the short cutting distance and the material flying out. It belongs to mechanical transmission and is widely used because of its simple structure and convenience.

  Rebar straightening machineThe principle is that the motor is accelerated by belt drive to make high-speed rotation. The oxide skin on the steel surface is eliminated by the straightening die. The motor drives the two conveying pressure rollers forward through another pair of speed reduction belts and gear reduction boxes. On the other hand, it drives the crank wheel to move the hammer up and down. When the steel rod is adjusted to a predetermined length, the hammer hits the knife holder to cut the steel rod. When the cut steel rod falls into the receiving frame, the knife holder returns to its original position under the action of the spring, and the cycle ends.

  Rebar straightening machineWhat are the operating procedures?

Pre -1. requirements: 1. Whether the inspection is suitable for the mechanical scope. 2. Is it fixed firmly. 3. Check whether the protective facilities are complete and reliable. 4, lubrication is not good. 5. Whether the placement of straightening die is correct. 6. Before use, the appropriate pressure roller groove width can be selected according to different diameters. In general, it should be ensured that the project penetrates the gap between the pressure rollers within 3mm. 7. Whether the electrical parts are damaged and the body grounding system is intact. Is the power supply voltage consistent with the voltage. 8, electricity consumption strictly implement the provisions of one machine, one brake, one box, one leakage protection.

2. job requirements. 1. Cleaning, refueling and repair are not allowed during the period. 2. When using automatic device, check whether the winch brake is flexible in advance. Pedestrians are not allowed to cross the positive cable. 3. Do not lift the conveying roller at will to avoid damage. 4. The end of the straight rod should be 8Ocm. After stopping, loosen the guide hole at the front end, and then start to pass through the cylinder to avoid hurting people.

Post -3. requirements. 1. Turn off the power and protect the electrical switch. 2, according to the requirements of daily maintenance work.

4. other aspects.

1. No objects shall be piled up to prevent mechanical vibration from falling into the body. 2. Enter the drum and keep a certain distance between the hand and the drum. The roller cannot be adjusted while running. It is forbidden to wear gloves during the operation. 3, transfer to the end, personnel need to pull over, in case of swing hurt. 4. Straightening with a diameter of less than 2m or more than 9mm should be processed at low speed. 5, the operator needs to hold a certificate.

  Rebar straightening machineThe structure is that the angle of the straight wire die can be adjusted by high speed and rotation of the rotor to achieve the effect. Then we can forward the wire through the wire wheel. After the wire reaches the required size, we touch the positioning key and push the walkway forward by 5mm. The upper punch presses the vertical line cutter to cut off the wire immediately. The wire is pressed by the pressure plate on the vertical line cutter to press the open bearing, and the wire automatically falls into the wire rack. To change the length, please move the positioning key.
