250 CNC Cold Bending Machine Precision Horizontal Arch Bending Machine Instructions for Use
CNC cold bending machines are now widely available in the market, and they can complete the bending and arching tasks of various types of steel, including channel steel, track steel, and round steel pipes. Different types of steel arches and arches with different angles require different grinding tools. The recognition of the bending machine in the market is very high now. Greatly improving the construction speed of profiles and saving labor for workers.
What is the processing accuracy of the I-beam cold bending machine
1. The error range of arch beam docking. The cold bending machine is strictly controlled from production to factory testing, ensuring that the docking error range of the arch beams produced and processed by each cold bending machine is within ± 0.76mm. This is more conducive to construction and the strength of the beam support.
2. Precision of steel curvature. The main factors affecting the quality of steel products are whether the hydraulic oil pressure is stable, and whether the steel plate and clamping wheel are level. The cold bending machine produced by our factory is equipped with a hydraulic feedback stabilizing device, which only requires setting the position of the top wheel. When the oil pressure decreases and there is no stable pressure, the top wheel will retreat under the pressure generated by the steel, resulting in inconsistent curvature. Cold bending machines can achieve constant pressure through pressure regulation, and the bent steel is the same without roots.
3. The absence of warping and wrinkles in steel mainly depends on whether the steel plate base and clamping wheel can be kept in the same horizontal position. Cold bending machines must pass horizontal calibration before leaving the factory, with a horizontal error not exceeding 0.12250. CNC cold bending machines and precision horizontal arch bending machines are used according to the instructions.
When changing the oil, colleagues should clean the fuel tank and filter screen. Be careful not to use a brush to clean the fuel tank. The basic principle of straightening mechanism for I-beam cold bending machine: For I-beams with defects such as side bending and warping, sufficient pressure is applied in the opposite direction by the straightening mechanism to induce deformation. If the deformation in the opposite direction is appropriate, then after rebound, the I-beam can be completely straightened. If the I-beam undergoes twisting deformation in a certain direction, the straightening mechanism rotates the I-beam in the opposite direction, resulting in plastic deformation. If the rotation angle is appropriate, after rebound, the I-beam will no longer twist. Details of precautions for I-beam bending machine: The active roller and passive roller are made of special materials and undergo overall heat treatment to reduce wear and tear on the ship, without scratching the workpiece, and have a longer service life. The hydraulic system of the WGJ250 upgraded hydraulic I-beam bending machine adopts advanced hydraulic components. The details of the precautions and unique hydraulic system design of the I-beam bending machine include the addition of a top out rebound device, which enables strong top out and extends the service life, avoiding frequent maintenance of the 250 digital control cold bending machine and the precision horizontal bending machine.
