Cold bending method of light steel keel cold bending machine

Cold bending industry is a new industry developed in recent decades, because of its simple and reliable equipment, low production cost, no pollution and a series of advantages in recent years has been widely developed. Cold bending is to roll the formed strip steel through different shapes of molds to make its shape and hardness meet the standards of practical application, and then cut it into the required length by hydraulic cutting or flying saw cutting. Light steel keel machinery is a kind of building materials machinery. With the increase of steel cost, more and more low production cost and production efficiency are required.
There are two cold bending methods of light steel keel cold bending machine. Due to the limited plasticity of steel pipe in cold state and the laborious bending process, cold simmer bending of light steel keel cold bending machine is suitable for small and medium-sized pipe diameter less than 175mm and steel pipe with large bending radius (R≥20).
The cold bending method of light steel keel cold bending machine has two kinds: manual cold bending and mechanical cold bending. Manual cold bending is made by means of tube bending plate or tube bender, while mechanical cold bending relies on external force to drive tube bending machine. The simple method of cold bending is to simmer the bending plate. The bending plate can be made of hard wood with thickness of 30~40mm, width of 250~300mm and length of about 150mm. A round hole is opened on the plate according to the outer diameter of the pipe that needs hydrocarbon bending, and the pipe is inserted into the hole when it is simmered, and the sleeve is used as a lever to artificially apply force to bend. This method is suitable for simmer pipe diameter is small and bending Angle is not about the bend pipe, such as the branch pipe connected to the radiator bend back and forth.
Roller bender cold bending: roller type bender, which is composed of fixed roller, movable roller, pipe holder and lever. When bending the pipe, the pipe to be bent is inserted between two rollers, one end is fixed by the clamp, and then rotate the lever, so that the movable wheel drives the pipe to rotate around the fixed wheel, the pipe is pulled and bent, and the bending Angle is reached after the rotation of the lever.
