Description
Technical field
The invention belongs to quenching unit field, especially a kind of double frequency induction load device.
Background technology
So there is currently for gear the workpiece of convex-concave surface structure, when using induction hardening, conventional single-frequency induction heating technique cannot realize gratifying induction heat treatment effect.Because gear has convex surface and concave surface, teeth portion surface hardening is carried out using high-frequency induction heating, the heat that faradic current produces is rapidly transferred to the center of gear, tooth top obtain fully hardened, but tooth root under-ageing.Additionally, this processing method is also easy to increase residual stress on the flank of tooth, lead to the generation ruptured.The same teeth portion surface hardening carrying out gear using Frequency Induction Heating, heat is conducted in tooth root, due to the concave of tooth root, is successively decreased with exponential form, tooth root is effectively hardened during heat conduction, and tooth top under-ageing.
Content of the invention
The present invention provides a kind of double frequency induction load device, its purpose is to solve the problems, such as that high frequency and intermediate frequency can not replace induction heat treatment.
In order to solve above-mentioned technical problem, the technical scheme is that：A kind of double frequency induction load device, including high-frequency quenching transformator, intermediate-frequency quenching transformer and quenching inducer it is characterised in that：The input of high-frequency quenching transformator is passed through load connection row and is connected with the first dual frequency power supplies switch and the first capacitor plate successively, and the first capacitor plate is provided with the high frequency capacitance being fixedly connected；The input of intermediate-frequency quenching transformer is passed through load connection row and is connected with the second dual frequency power supplies switch and the second capacitor plate successively, and the second capacitor plate is provided with the intermediate frequency electric capacity being fixedly connected；The input of the first capacitor plate and the second capacitor plate is connected with the 3rd capacitor plate；The outfan of high-frequency quenching transformator and intermediate-frequency quenching transformer passes through bus-bar and quenching inducer, the 3rd dual frequency power supplies switch and the 3rd capacitor plate cycling circuit in series.
Beneficial effect：The present invention has advantages below：1. induction heat treatment is replaced using high frequency and intermediate frequency, the uneven difficult problem of tissue contours occurs after solving single-frequency Quenching Treatment well, dual-frequency p-code can make the tooth root of gear and tooth top can thermally equivalent, good hardened layer can be obtained after quenching.2. compared with prior art, the advantage of this device：Range is wide, can obtain the part of preferable impewdance matching tissue, and the workpiece service life obtaining uniform formation after quenching is longer, is that user is cost-effective, creates more value, this dual-frequency p-code device environmental pollution is little simultaneously, quenching efficiency is high.

Specific embodiment
As shown in Figure 1, a kind of double frequency induction load device, including high-frequency quenching transformator 1, intermediate-frequency quenching transformer 2 and quenching inducer 3, the input of high-frequency quenching transformator 1 is passed through load connection 4 rows and is connected with the first dual frequency power supplies switch 5 and the first capacitor plate 6 successively, and the first capacitor plate 6 is provided with the high frequency capacitance 7 being fixedly connected；The input of intermediate-frequency quenching transformer 2 is passed through load connection row 4 and is connected with the second dual frequency power supplies switch 8 and the second capacitor plate 9 successively, and the second capacitor plate 9 is provided with the intermediate frequency electric capacity 10 being fixedly connected；The input of the first capacitor plate 6 and the second capacitor plate 9 is connected with the 3rd capacitor plate 11, and that is, the first capacitor plate 6 and the second capacitor plate 9 constitute parallel circuit by the 3rd capacitor plate 11；The outfan of high-frequency quenching transformator 1 and intermediate-frequency quenching transformer 2 pass through bus-bar 12 successively with quenching inducer 3, the 3rd dual frequency power supplies switch 13 and the 3rd capacitor plate 11 cycling circuit in series.
The structure of dual frequency power supplies switch is by application number：201420130089.9 patent document open.Unspecified part in this specification, the technology being known in the art.
Operation principle：As shown in Fig. 2 when tooth type parts quenching works, intermediate-frequency quenching transformer first works after a period of time, second dual frequency power supplies switch disconnects, first dual frequency power supplies switch closure, completes the purpose that intermediate-frequency quenching transformer is switched to high-frequency quenching transformator, high-frequency quenching transformator is started working.The induction hardening transformer alternation of two different frequencies, realizes top and the heel thermally equivalent of tooth class part, can obtain uniform profile hardened layer after quenching.3rd dual frequency power supplies switch is the main switch controlling high-frequency quenching transformator and intermediate-frequency quenching transformer circuit.
