A Portable Handheld Transformer for Induction Heating

Abstract

The invention discloses an induction-heating portable hand-held transformer comprising a hand-held housing. The transformer is arranged in the hand-held housing and comprises an external metal cylindrical body; the front and back ends of the external metal cylindrical body are respectively provided with a front end cover plate and a back end cover plate for sealing; an annular magnetic core is disposed in the external metal cylindrical body; the annular magnetic core is provided with a primary side lead to form a primary side winding set; one end of the primary side lead is connected to a water-electricity separation joint; a central hollow rod is disposed in the external metal cylindrical body; and the central hollow rod passes through the annular magnetic core to be connected with an auxiliary side joint of the front end cover plate and a water inlet pipe of the back end cover plate to form an auxiliary side loop to output power. The transformer is simply structured, has light weight and can be easily moved; functions, such as welding, quenching and metal melting of old water-cooled transformers can be realized; and the transformer has unparallel advantages in the field of metal tube wall powder re-melting.

Description

【Technical field】 [0001] The invention belongs to the technical field of high-frequency induction heating power supply, and in particular relates to a portable portable transformer for induction heating. Applied to the welding of special-shaped workpieces, and the welding of non-accurately positioned workpieces. 【Background technique】 [0002] The high-frequency induction heating transformer is the main component of the power inverter. The high-frequency induction heating transformer commonly used is a discrete combined water-cooled transformer, which is generally composed of a primary side, a secondary side, a magnetic core, a heat dissipation mechanism, a compression mechanism and a chassis; The primary side is generally composed of water-through copper tubes or electromagnetic wires. Most of the magnetic cores are E-shaped cores, and the secondary side is wound with water-through copper tubes. core; the existing transformer has a large volume and heavy weight due to its ...

[0002] The high-frequency induction heating transformer is the main component of the power inverter. The high-frequency induction heating transformer commonly used is a discrete combined water-cooled transformer, which is generally composed of a primary side, a secondary side, a magnetic core, a heat dissipation mechanism, a compression mechanism and a chassis; The primary side is generally composed of water-through copper tubes or electromagnetic wires. Most of the magnetic cores are E-shaped cores, and the secondary side is wound with water-through copper tubes. core; the existing transformer has a large volume and heavy weight due to its structure and coupling form; welding of special-shaped workpieces and workpieces without accurate positioning cannot be completed; at present, flame welding is mostly used;
