Medium frequency pipe bender adopts medium frequency induction heating to bend the workpiece under the condition of local heating. Compared with the general cold pipe bender, it does not need a complete set of special die, and also the volume of the machine only accounts for 1/3 ~ 1/2 of the same specifications of the cold pipe bender. The medium frequency hot pipe bending process is the most economical and effective one among all kinds of pipe bending processes.
Medium frequency pipe bender features:
1) The process can avoid the phenomenon of uneven wall thickness caused by tensile thinning of the convex edge of the pipe wall and compression thickening of the concave edge of the pipe wall during the forming of the traditional bending process.
2) The small radius (R≈D) and thin wall (t/D≈0.015) 180 elbow with uniform wall thickness can be produced by using this process, which can not be achieved by other bending processes.
3) If the design of various process parameters is reasonable, the process can ensure that the thickness of the pipe wall in each position is always unchanged during the forming process of the elbow, that is, it is always equal to the thickness of the straight pipe blank before deformation.
4) The technology can be used to push the same horn mandrel at one time to produce the same caliber of 45°, 90°, 180° and other bending angles of the bend pipe, high production efficiency.
Medium frequency pipe bender use:
Mainly used for bending non-ferrous or ferrous metal pipes, suitable for building materials, shipbuilding, chemical, metallurgy, boiler and heavy machinery manufacturing sectors. The products are mainly used in the construction of arc steel structure, tunnel support, car roof curved beam, subway engineering, aluminum doors and Windows, ceiling, cylinder frame, balcony armrest, shower door, production line track, fitness equipment and other industries.
Intermediate frequency bend is that steel pipe bending set in the process of induction coil, use rocker arm to hold the pipe. The intermediate frequency induction coil current heating tube, when the steel tube temperature reaches setting value, the steel pipe end with mechanical thrust forward, bending, cool steel tube with coolant rapidly, while advancing, bending, and cooling, Keep bending the bend out. With the development of domestic pipe fitting manufacturing industry, intermediate frequency pipe bending manufacturing technology is also constantly improving.
