Problems solved by technology

[0004] However, even with this high-frequency sealing machine, the metal sleeve of the manufactured PTC liquid heating tube still has the risk of cracks in the metal tube at the seal due to the existence of metal oxides, and the rough surface of the weld will cause the heating liquid to be damaged. The outer surface of the metal pipe is easy to rust during the process. The high-frequency heating device and high-frequency induction coil of the device are located on the upper part of the main machine. During the movement process driven by the oil cylinder, the vibration generated will cause the machine to shift, and even the machine Danger of tipping, threatening the personal safety of the relevant staff

Abstract

The invention relates to the field of pipe fitting machining equipment, in particular to high-frequency heating metal pipe sealing equipment which comprises a round pipe feeding device, a high-frequency heating device and a rolling device. A rolling device used for sealing a notch of the round pipe is arranged on the other side of the front end of the round pipe feeding device, a polishing device used for polishing the sealed portion of the round pipe is arranged at the front end of the round pipe feeding device, and a file is arranged below the polishing device and comprises a round pipe surface file body and a notch file body. The automatic sealing equipment for the metal pipe ports is high in sealing efficiency, small in welding stress at the sealing position, smooth and not prone to rusting on the surface of the welding position and safe and stable in the working process, and has the beneficial effects that in the spinning machining process, the circular pipe ports are more easily combined, the closing-up part is smooth and flat, and the working efficiency is improved. And the shell nosing part can be manufactured into an arc shape or a plane shape according to requirements, cutting and polishing are not needed after shell nosing, welding stress is avoided, and the sealing effect is good.

Description

technical field [0001] The invention relates to the field of pipe fitting processing equipment, in particular to a sealing equipment for high-frequency heating metal pipes. Background technique [0002] PTC heating tubes are usually composed of PTC ceramic heating elements and metal outer sleeves. The PTC heating element has the advantages of small thermal resistance and high heat exchange efficiency. It is an electric heater with automatic constant temperature and power saving. When making liquid PTC heating rods, it is often necessary to seal one end of its metal outer sleeve. In the existing technology on the market, the sealing process of pipe fittings is mostly completed by plugging. The gap between the head and the pipe wall is welded. In this welding process, there are problems such as high cost, long time consumption, many processing steps, weld scars left at the weld, and the appearance is not beautiful and needs to be polished. At the same time, there are still pr...
