Specific embodiment
In the description of the present invention, it is to be understood that, the orientation or positional relationship of the instructions such as term " on ", "lower" is base
In orientation or positional relationship shown in the drawings, it is merely for convenience of description of the present invention and simplification of the description, rather than indication or suggestion
Signified device or element must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as to this
The limitation of invention.
Combined with specific embodiments below, the contents of the present invention are described in further detail, Fig. 1 is shown in the present invention
The heat treatment assembly stereoscopic schematic diagram of the first embodiment of pallet, mainly by structures such as substrate 1, cover board 2 and sealing rings 3
At, wherein cover board 2 is fastened on the surface of substrate 1, and above-mentioned sealing ring 3 is located between the two to form seal chamber.In base
Multiple storing grooves 11 are evenly equipped on plate 1 in the sealing area of plane, for realizing the fixation to air core inductor (such as institute in Fig. 2
Show).It so, can effectively will be hollow by means of the seal chamber of pallet during the Post isothermal treatment to air core inductor
Inductance is isolated with melting salt made from earth containing a comparatively high percentage of sodium chloride, the risk that air core inductor suffers erosion is avoided, to eliminate in normative heat treatment technique
Cleaning, coating anti-corrosion liquid and air-dried process, greatly increase the heat treatment efficiency of air core inductor, and reduce production
Cost.
In order to ensure the stability that air core inductor is fixed, prevents it to be heated in subsequent heat treatment technical process and plasticity occurs
Deformation needs to control the unilateral gap value between fixed groove 11 and air core inductor in 0.2mm hereinafter, and its depth value and empty
The height value of electrocardio sense is consistent.
It should be noted that in order to ensure melting the heat transfer efficiency of salt made from earth containing a comparatively high percentage of sodium chloride and pallet, above-mentioned substrate 1 and cover board 2
It chooses highly heat-conductive material to be made, such as copper and copper alloy.In addition, sealing ring 3 is also chosen by high heat resistant rubber ring, such as entirely
Fluorubber ring, instantaneous highest heatproof is up to 327 DEG C.Certainly, optimal to be selected as graphite pressure sealing ring.
For preventing sealing ring 3 from occurring position change in use, and then influence to examine in terms of the leakproofness of seal chamber
Consider, an annular groove 12 (as shown in Figure 2) can also be opened up around the periphery of substrate 1, for putting above-mentioned sealing ring 3,
To realize being reliably fixed for its position.Certainly, the particular number of above-mentioned annular groove 12 and open up position can be according to reality
Situation is selected.Certainly, it is analogous to the set-up mode of aforesaid substrate 1, can also be opened up around the periphery of cover board 2 for putting
The annular groove of above-mentioned sealing ring.It needs to point out herein, leakproofness and installation convenience, need pair in order to balance
Sealing ring 3 and the unilateral gap of 12 side wall of annular groove are controlled, and are generally advisable with 0.2-0.3mm.
Furthermore it for the ease of the progress of 2 installation process of cover board, must be removably attached with substrate 1, preferably
Scheme is as follows: cover board 2 is removably fastened on the upper surface of substrate 1 by means of screw, along the periphery of cover board 2 offer it is multiple with
The compatible through-hole 21 (as shown in Figure 3) of the screw correspondingly offers multiple threaded holes 13 in the corresponding position of substrate 1
(as shown in Figure 2).It is known that in the long-term use, threaded hole 13 is easy to be worn, so as to cause substrate 1 it is impaired,
Failure, for this purpose, can 13 region of threaded hole to substrate 1 carry out selective hardening processing, to improve the surface hardness of its thread.When
So, wear-resistant coating can also be coated in the inner wall of threaded hole 13.
In general, the thickness of substrate 1 is larger, and general control is in 25-30mm, thus the heat between pallet and melting salt made from earth containing a comparatively high percentage of sodium chloride
Exchange efficiency is lower, reduces the temperature rise speed of pallet, thereby reduces the temperature rise speed of air core inductor, is unfavorable for aging technique
Execution.Fig. 4 shows the assembly stereoscopic schematic diagram of second of embodiment of heat treatment pallet in the present invention, compared to upper
The distinctive points for stating the first embodiment are, open up deflector hole 15 (in such as Fig. 5 in the side wall of substrate 1, against storing groove 11
It is shown), so, effectively increase the heat exchanger effectiveness between melting salt made from earth containing a comparatively high percentage of sodium chloride and pallet.Specific design method is recommended as follows:
The quantity of deflector hole 15 is set as multiple, uniformly distributed along the length direction of substrate 1.
In order to improve melting salt made from earth containing a comparatively high percentage of sodium chloride and pallet heat exchanger effectiveness, reduce the heat treatment time of air core inductor, as more into
The optimization of one step can also be provided with herringbone corrugation grooves 14 (as shown in Figure 6), cover board 2 on the non-binding face of substrate 1
It is analogous to aforesaid substrate 1 and is configured (as shown in Figure 7).So, during being heat-treated, melting salt made from earth containing a comparatively high percentage of sodium chloride can
To be flowed along above-mentioned herringbone corrugation grooves 14, heat exchange distance is extended, to improve heat exchanger effectiveness.Separately
Outside, the presence of above-mentioned herringbone corrugation grooves 14 can also form certain flow-disturbing in the cavity of salt made from earth containing a comparatively high percentage of sodium chloride tempering furnace, to increase
Heat exchanger effectiveness between strong melting salt made from earth containing a comparatively high percentage of sodium chloride.
In addition, the invention also discloses a kind of heat treatment methods of tin bronze wire air core inductor comprising following steps:
A, the air core inductor batch after forming is placed in above-mentioned heat treatment pallet;
B, heat treatment pallet being placed in salt made from earth containing a comparatively high percentage of sodium chloride tempering furnace and carries out ageing treatment, aging temp is controlled at 350 ± 5 DEG C,
Time controls in 5-10min;
C, after completion of prescription, heat treatment pallet is placed to cooling in 5-20 DEG C of coolant liquid, is no less than 2min cooling time;
D, each air core inductor is taken out from heat treatment pallet.
The operating method of tin bronze wire air core inductor heat treatment is as follows: 1, storing air core inductor being placed on substrate is recessed
Slot;2, cover board is placed in the surface of substrate, screw is borrowed and is locked, to form sealing cavity therebetween;3, right
The leakproofness of sealing cavity is tested;4, pallet is implanted to salt made from earth containing a comparatively high percentage of sodium chloride tempering furnace after test passes, is heat-treated.
The experimental results showed that, when aging temp is also controlled at 350 DEG C, aging time is controlled in 7min space-time by long-term
Heart inductance coil has the smallest elastic recovery amount, it is ensured that the progress and real work performance of its subsequent assembling process.
Finally, it should be noted that above-mentioned coolant liquid, which can be selected, to be obtained aspect, utilizes lower-cost cooling water.Certainly,
It can also be required, be chosen using cooling oil as cooling medium according to actual process.Cooling oil is compared to cooling water, air core inductor line
Circle has more smooth temperature drop curve, so that it be made to obtain preferably thermal effectiveness.
