Description

TECHNICAL FIELD

[0001] The utility model relates to the elbow, elbow processing field, concretely is a kind of inductive coil position adjusting device. BACKGROUND

[0002] The intermediate frequency induction heating push technology is widely applied in elbow production, and its processing technology is described in the publication No. "CN117817364A". When the steel pipe passes through the induction coil, due to the induction coil passing through the alternating current of a certain frequency, the magnetic flux through the steel pipe changes with the current, and the steel pipe is regarded as a layer of cylindrical "shell" composed of a layer of cylindrical "shell". Each layer of "shell" is equivalent to a loop. Since the magnetic flux through the "shell" section is constantly changing, the loop equivalent to each layer of "shell" will excite an induced electromotive force, forming a ring-shaped induced current. Since the conductor resistance of the metal steel pipe is very small, the eddy current is large, and the heat effect is generated, thereby playing an induction heating role.

[0003] In order to improve the intermediate frequency induction heating efficiency, reduce the magnetic flux leakage, increase the magnetic flux per unit time, and ensure that the steel pipe does not touch the induction coil during the hot pushing process, the distance between the induction coil and the outer surface of the steel pipe should be as short as possible (the distance is preferably controlled to be less than 3mm). In view of the change of the size of the processed steel pipe and the bending degree of the steel pipe, it is often necessary to adjust the position of the induction coil. At present, the existing induction coil is usually fixed on the quenching transformer by a clamp, and the position adjustment mainly depends on the structure of the jack or air cylinder to lift vertically. Although the height of the induction coil can be adjusted, the induction coil cannot be adjusted in pitch angle by the structure of the jack, and the rotation angle of the coil cannot be adjusted corresponding to the steel pipe with different bending degrees, so it is urgent to be solved.
