The anchor nut high-frequency annealing device improves the stability of the high-frequency induction heating annealing quality of the anchor nut and the operability of the technological process. The anchor nut high-frequency annealing device does not change the technological process of high-frequency annealing of the anchor nut.
Description
Technical field
The present invention relates to a kind of plate nut high frequency annealing device, belong to plate nut processing technique field.
Background technology
For a kind of plate nut of aircraft engine, material is superalloy, after heat treatment process, bulk strength is higher, but in use need this plate nut to turn over riveting on base plate, this just requires to anneal at afterbody thin-walled position high-frequency induction heating coil, to change matrix higher for thin-walled position intensity into intensity lower annealed structure by annealing.But original method for annealing is when induction heating, if load coil is close to plate nut, the basal body of nut connecting plate nut thin-walled position heats with regard to easy by together, have influence on the intensity of basal body of nut, can find matrix coarse grains when making metallographicinspection in this case, intensity decreases.If load coil is away from plate nut, thin-walled position just may be caused to anneal insufficient, may ftracture when turning over riveting, affecting the use of plate nut.Use this refrigerating unit that heat can be avoided to be delivered to plate nut matrix fast, make fully anneal and can not impact matrix during thin-walled portion induction heating.
Summary of the invention
Object of the present invention overcomes the defect existed in prior art, thus provides a kind of easy to operate, and thin-walled annealing is abundant, on the plate nut high frequency annealing device of matrix without impact.
For solving the problems of the technologies described above, the present invention adopts following technical proposals:
A kind of plate nut high frequency annealing device, includes a load coil 2; This annealing device also includes the refrigerating unit 3 of the matrix end of a screw-in plate nut 1.
Adopt the beneficial effect of technique scheme:
1, structure of the present invention is simple, only in original induction heating equipment, adds refrigerating unit, and do not make other to equipment and change, process easily realizes.
2, invention increases the stability of plate nut high-frequency induction heating annealing quality, improve the operability of this technological process.
3, the present invention does not change the technological process of plate nut high frequency annealing.

Fig. 1 is the plate nut structural representation of processing required for the present invention;
Fig. 2 is the structural representation of former plate nut high frequency annealing device;
Fig. 3 is the structural representation of a kind of plate nut high frequency annealing of the present invention device;
In figure: 1-plate nut, 2-load coil, 3-refrigerating unit.
Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail.But not as any limitation of the invention foundation.
A kind of plate nut high frequency annealing device, includes a load coil 2; This annealing device also includes the refrigerating unit 3 of the matrix end of a screw-in plate nut 1.
The present invention is by increasing a set of refrigerating unit 3 (the copper alloy swivel nut that this refrigerating unit is closed by an one side and a plug screw, and screw in the water inlet pipe and water outlet pipe composition of plug screw, pass into tap water after combination and taken away the heat come from plate nut transmission by the water inlet pipe cavity entered between swivel nut and plug screw .) take away the heat of the matrix being delivered to plate nut 1 from thin-walled position, the temperature of the matrix of plate nut 1 is allowed to remain on below certain temperature range, reach matrix unannealed, the sufficient object and thin-walled portion is annealed.Operationally allow the position between load coil 2 and plate nut 3 that larger moving range (can very close to body portion) can be had all can not to affect the annealing of thin-walled position and matrix is unaffected.Because refrigerating unit has taken away the heat of matrix, convenient when operating, thin-walled annealing is more abundant, on matrix substantially without impact.
The present invention screws in refrigerating unit 3 at the matrix end of plate nut 1, when load coil 2 carries out high-frequency induction heating by high-frequency induction to the thin-walled portion of plate nut 1, because refrigerating unit 3 acts on, prevent heat to be delivered to matrix, realize the function of only plate nut 1 thin-walled position being carried out to annealing heating.
Claims (1)
1. a plate nut high frequency annealing device, includes a load coil (2); It is characterized in that: this annealing device also includes the refrigerating unit (3) of the matrix end of a screw-in plate nut (1).
