Arc elbows are mostly used in venues, theatres, large-span steel arch trusses and other projects are widely used.

1. Features.

Arc elbow processing using medium-frequency elbow machine heating, according to different pipe materials to set the corresponding temperature, after medium-frequency induction heating using water-cooled or air-cooled molding. The material of the round tube is not affected, and the arc of the arc elbow can be effectively controlled.

2. Scope of application.

Main string bar elbows (round tube, square torque tube, H-type steel, conical tube) for large steel trusses and bridge structures.

3. Process principle.

Medium frequency induction heating: is a power supply device that converts the frequency 50HZ AC to the medium frequency (300HZ to 20K HZ), turns the three-phase ac Becomes an adjustable medium-frequency current, which supplies the medium-frequency cross-change current flowing through the capacitor and induction coil, generates high-density magnetic lines in the induction ring, and cuts the metal material in the induction ring, creating a large eddy current in the metal material. This vortex also has some of the properties of the medium-frequency current, i.e., the free electrons of the metal itself flow in a resistive metal body to generate heat. For example, put a steel pipe in the induction ring with the intermodulation medium frequency current, the steel pipe does not have direct contact with the induction coil, through the wire coil itself temperature has been very low, but the surface of the steel pipe is heated to redness, or even melting, and the speed of redness and melting as long as the adjustment of frequency size and current strength can be achieved. If the steel pipe is placed in the center of the coil, then the temperature around the pipe is the same, the steel pipe heating and melting also does not produce harmful gases, strong light pollution of the environment. The advantages of mid-frequency induction heating:

The heating speed is fast, oxidizing decharcoal less because the principle of medium frequency induction heating is electromagnetic induction, its heat is produced in the workware itself, because the heating method heats up very fast, so oxidation is very small, heating efficiency is high, process repeatability is good.

The heating is uniform, the temperature control accuracy is high induction heating is easy to achieve the heating uniform, the core table temperature difference is small requirements. By controlling the frequency and current, the heating temperature of the steel pipe can be controlled at a temperature that meets the specification requirements.

Low energy consumption, non-polluting induction heating compared with other heating methods, high heating efficiency, low energy consumption, non-polluting;

The working principle of the medium frequency elbow machine is to heat the round tube by using the medium frequency power supply, and at the same time push the round tube at a constant speed, so that the round tube of the heating part walks along the preset track to form a component with a certain curvature radius and angle. First put the round tube in place, through the rocker swing device on the screw screw female transmission to adjust the bending radius, using the medium frequency induction heating ring to heat the round tube to a certain temperature after bending, bending with hydraulic power, by the car to push the steel pipe forward, along the adjusted bending radius in the heating place deformation and bending, the tube deformation after its natural cooling, so as to obtain the required arc composition.
