When should quench, by induction apparatuss piece surface can be made to produce faradic current, hardening heat and fast quickly cooling are reached so as to be rapidly heated
But quench, make piece surface reach high rigidity, core does not heat holding soft.Impewdance matching obtains will part different parts
Different hardened layer shapes, can be readily obtained and ensure the quench-hardened case requirement that any difficulty is required, hardened face does not have crackle, molten
The phenomenons such as change, core hardness is unchanged, and surface martensite tissue need to meet national standard.The impewdance matching for reaching the above will
Ask, be crucial from the frequency of impewdance matching, too high frequency easily makes piece surface temperature too high, causes part tissue after quenching
Thick and surface melting；Too low frequency easily makes piece surface temperature too low, causes part harmful structure and surface after quenching hard
Spend low.Therefore impewdance matching needs depth of hardening zone as requested to select suitable frequency.For in existing series-connection power supplies
Frequency quenching press, as shown in figure 1, induction apparatuss 8 are enclosed within power transmission shaft 7 but not with power transmission shaft 7 contacting, is moved by the left and right of induction apparatuss 8
It is dynamic that impewdance matching is carried out to power transmission shaft 7, but it can not adjust the electricity of induction hardening by the turn ratio of adjustment transformator
Source frequency, can not adjust the supply frequency of impewdance matching by adjusting electric capacity.In particular for solid shafting impewdance matching, no
Deeper quench-hardened case can be met to require.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of induction apparatuss for series-connection power supplies mid frequency induction hardening machine,

In order to solve above-mentioned technical problem, this utility model is adopted the following technical scheme that：One kind is used for series-connection power supplies intermediate frequency
The induction apparatuss of quenching press, including by the main induction circle in spring-like that takes two turns at least is returned, the main induction circle extends two use
In the connector being powered, described two connectors to the same side extends, is rotarily formed respectively on described two connectors and at least returns
Turn around the secondary induction coil in spring-like, and the main induction circle and the connector are the hollow structure with inner chamber for connecting,
Described two connectors are connected with water-cooling system.
Preferably, it is provided with insulating trip between the turning circle of the main induction circle.
Preferably, the end of described two connectors is connected by quick union with water-cooling system.
Preferably, the main induction circle outside is provided with retainer, and the retainer is connected with quenching press.
Preferably, the main induction circle and connector are copper material.
As described above, a kind of induction apparatuss for series-connection power supplies mid frequency induction hardening machine of this utility model, with following beneficial effect
Really：
This utility model is used for series-connection power supplies mid frequency induction hardening machine, and it can be effectively increased self-inductance by secondary induction coil, from
And supply frequency is reduced, the number of turns of secondary induction coil can be adjusted, and then meet power transmission shaft difference hardening according to practical situation
The quenching of layer depth is required.Especially solid transmission shaft, can be good at completing the quenching requirement deeper to depth of hardening zone, real
It is good with property.

Specific embodiment
Structure, ratio, size depicted in Figure of description etc., only to coordinate the content disclosed in description, with
Understand and read for those skilled in the art, be not limited to the enforceable qualificationss of this utility model, therefore do not have skill
Essential meaning in art, the modification of any structure, the change of proportionate relationship or the adjustment of size are not affecting this utility model institute
Under the effect that can be produced and the purpose to be reached, all should still fall what is covered in the technology contents disclosed in this utility model
In the range of.Meanwhile, in this specification it is cited such as " on ", D score, "front", "rear", " centre " term, be merely convenient to chat
That what is stated understands, and be not used to limit the enforceable scope of this utility model, and its relativeness is altered or modified, without substantive change
