[0004] However, during the continuous forming process of metal bellows, the surface of the bellows needs to be quenched to achieve a bellows with a hard surface and a tougher core, so as to withstand the bending and impact of external forces. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a continuous forming equipment for metal corrugated pipes, which, by setting a quenching mechanism and a heating mechanism, allows the surface of the corrugated pipe to be quenched during the continuous forming process to obtain a corrugated pipe with a hard surface and a tougher core, so as to withstand the bending and impact of external forces.

[0006] This utility model discloses a continuous forming equipment for metal corrugated pipes, including a heating mechanism; it also includes a filtering mechanism, a quenching mechanism, a rolling mechanism, a driving mechanism, and a conveying mechanism.

By opening the conveying mechanism, the material is conveyed; by opening the driving mechanism, the rolling mechanism is driven, thereby clamping and embossing the material; by opening the heating mechanism, the material is heated; by opening the quenching mechanism, the material is quenched; and by the filtering mechanism, the quenching oil is filtered. Thus, during the continuous forming process of the metal corrugated pipe, the surface of the corrugated pipe can be quenched to obtain a corrugated pipe with a hard surface and a more resilient core, which can withstand bending and impact from external forces.

[0008] Preferably, the heating mechanism includes a base plate and a heating coil, with the heating coil mounted on the upper end of the base plate; the heating coil is energized to magnetically heat the corrugated pipe.
