Classification:

1.Intermediate frequency bend

Intermediate frequency bend is by medium frequency induction heating, the workpiece bending under the condition of local heating.Compared with the general cold bend, not only don't need a complete set of special mould, and machine volume is only about a third of the same specifications of the cold tube bending machine ~ 1/2.Intermediate frequency heat pipe bending process is existing each kind of pipe bending process in one of the most economic and effective.

2.180 degrees push pipe

180 degrees push pipe making industry is to push bend soaking in the solution tank, preferably in the solution contains every litres of 250 grams of Cr2O3, every litres of 490 grams of sulfuric acid can also, temperature range 80 ~ 85 ℃, soak time depends on the color of the need, not more than 25 minutes.Will push system after bending work clean cold water rinse, then at room down on the concentration of 250 g / 1 chlorate and 2.5 g / 1 litres of phosphate cathode in the liquid, and time is about ten minutes, current density of 0.2 ~ 0.4 A/dm2.In order to prevent damage, color after processing hardening treatment immediately, and then in hot water to rinse and dry.An important characteristic of the process is the final look of it can reflect the material of the original surface.

3.U-shaped bend

U-shaped bend of complete sets of bending dies is adopted to bend, divided into two kinds of cold heat and hot push technology.Whether what kind of machinery, equipment and pipeline, mostly use bend, mainly used in oil, gas, fluids, etc., on aircraft and its engines more occupies an important position.
