Description

Technical Field

[0001] The utility model relates to the technical field of induction hardening heat treatment, in particular to an induction hardening transformer. Background Art

[0002] Induction heating heat treatment is a surface heat treatment process that locally heats the surface of a workpiece with an induced current. According to the characteristics of the output of the IGBT medium and high frequency power supply, it is necessary to reduce the voltage and increase the current to match the impedance of the inductor and the workpiece. The turns ratio of a conventional transformer is relatively single, with only one turn for each coil. The adjustment of the working frequency needs to be matched according to the adjustment of the turns. If the frequency is relatively low, the higher the frequency, the fewer the turns, and the lower the frequency, the more the turns.

[0003] The Chinese patent document with the authorization announcement number CN219246499U discloses "an induction hardening transformer, including a primary coil (2) and a secondary coil (3), characterized in that: the primary coil (2) includes a plurality of first coil groups (21) arranged in sequence from top to bottom, and the first coil group (21) is wound by at least one turn of copper pipe...". However, the above technical solution still has the following defects in use:

[0004] The frequency adjustment range of the existing induction hardening transformer is relatively limited and it is difficult to adapt to the adjustment range of 2000HZ - 40KHZ; because a large amount of cooling water is required for the transformer to work to take away heat, the heat conduction water pipes distributed in the transformer are relatively messy. In particular, when the cooling water scale is cleaned regularly, the water inlet and outlet of the cooling water pipes are easily misaligned. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides an induction hardening transformer, which solves the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model adopts the following technical solution: an induction hardening transformer, including a bottom plate, side plates, a rear plate and a front plate. The front plate and the rear plate are respectively fixedly installed on the front side and the rear side of the top surface of the bottom plate, and the number of the side plates is two and they are respectively fixed on both sides of the top surface of the bottom plate. The front plate surface penetrates and is fixedly inserted with an upper secondary coil group and a lower secondary coil group, and the upper secondary coil group is installed above the lower secondary coil group;

[0007] An L-shaped water divider, a partition plate and a magnetic core are arranged on the left side of the lower secondary coil group on the top surface of the bottom plate, and the L-shaped water divider and the magnetic core are respectively located on both sides of the partition plate;

[0008] At the rear side of the next secondary coil group on the top surface of the bottom plate, a first turn coil and a second turn coil are provided. The back ends of the first turn coil and the second turn coil are fixedly inserted and installed in the middle of the back plate surface, and the main bodies of the first turn coil and the second turn coil are both made of flat T1 copper tubes.

[0009] Preferably, the L-shaped water distributor includes a water distributor rectangular pipe, a water distributor transverse rib pipe, and water distributor nozzles. The water distributor transverse rib pipe is fixedly installed at the bottom of the water distributor rectangular pipe and is connected to its interior. The number of water distributor nozzles is multiple and they are respectively connected and inserted into the front side wall and the back side wall of the water distributor rectangular pipe.

[0010] Preferably, the upper secondary coil group includes a secondary plate, a connecting elbow, a first base, a second base, a long water nozzle, and a short water nozzle. The first base and the second base are both fixedly installed at the front end of the secondary plate. The long water nozzle and the short water nozzle are distributed and connected to the opposite sides of the first base and the second base. The connecting elbow is connected and installed with the end of the short water nozzle, and the upper secondary coil group and the lower secondary coil group have the same structure.

[0011] Preferably, coil waterway connectors are fixedly installed at the ends of the first turn coil and the second turn coil, and the interiors of the first turn coil and the second turn coil are connected to the interiors of the coil waterway connectors.

[0012] Preferably, cushion plates and pressure bars are provided above the upper secondary coil group and below the lower secondary coil group, and the pressure bars are fixedly installed at both ends of the cushion plates. Stainless steel socket head cap screws are longitudinally inserted into the pressure bars above the upper secondary coil group and below the lower secondary coil group.

A top plate is fixedly installed at the top ends of the bottom plate, the side plates, the back plate, and the front plate, and the bottom plate, the side plates, the back plate, the top plate, and the front plate are all made of epoxy board.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows: For this induction hardening transformer, by setting both the first turn coil and the second turn coil body to adopt flat T-shaped copper tubes, the first turn coil and the second turn coil can be successively superimposed with the first turn coil and the second turn coil serving as the secondary and the primary respectively. Water is passed through the first turn coil and the second turn coil and connected to the L-shaped water distributor, so that the number of turns of the first turn coil and the second turn coil can be easily adjusted, which is very convenient for adapting to the adjustment ranges of various frequencies and meeting the hardening requirements of multi-band frequency ranges. Moreover, using flatly superimposed T-shaped copper tubes as the turn coil structures - the first turn coil and the second turn coil, it is not easy to generate water scale inside, reducing the maintenance cost and the situation of wrong pipeline connection caused by frequent cleaning. At the same time, the simplification of the water circuit also reduces the failure rate of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS
