Background technology
Diaphragm spring is one of vitals on the automobile diaphragm clutch, plays platen is produced snap-in force and cuts off effects such as power, override protection, and the performance of diaphragm spring and life-span have determined each item index work-ing life of clutch coupling; Diaphragm spring last procedure in manufacturing processed is thermal treatment, and at present, what prior art adopted basically is the mode of resistance furnace heating; Like this heating period long, importantly, be easy to generate oxidation or decarburization phenomenon for avoiding diaphragm spring in air, to heat; Need the ambient oxidation protection; The long-time energy that consumes is also many, simultaneously, adopts the hardness of the diaphragm spring that this technology produces limited; The fatigue lifetime of diaphragm spring relative also more limited, this just exists certain weak point.
Summary of the invention
Technical problem to be solved by this invention is the deficiency that overcomes prior art, provides a kind of heating period weak point, good energy-conserving effect, the diaphragm spring that can improve hardness and prolong fatigue lifetime to press the Processes and apparatus of quenching.
Diaphragm spring of the present invention presses the technical scheme that technology adopted of quenching to be: the diaphragm spring of rotation carries out cutting magnetic line movement in high frequency magnetic field.
Further, diaphragm spring is arranged on makes its rotation on the swivel arrangement, the high-frequency current generating unit provides high-frequency current to ruhmkorff coil, and diaphragm spring is located in the high frequency magnetic field that ruhmkorff coil produces, and carries out cutting magnetic line movement.
Further, the power of said high-frequency current generating unit is 200-250KH
Z
Diaphragm spring of the present invention presses the technical scheme that equipment adopted of quenching to be: the said pressure equipment of quenching comprises swivel arrangement, ruhmkorff coil, high-frequency current generating unit; Said high-frequency current generating unit is electrically connected with said ruhmkorff coil; During work; Said diaphragm spring is arranged on the said swivel arrangement and rotates, and cuts the high frequency magnetic field that said ruhmkorff coil produces, and produces inductive current.
The said pressure equipment of quenching also comprises TP, intelligence controlling device, and said wheelwork, said high-frequency current generating unit, said TP all are electrically connected with said intelligence controlling device.
Said TP is a high frequency-infrared line TP.
The invention has the beneficial effects as follows: compared with prior art, the present invention has adopted the mode of high-frequency quenching, and promptly the diaphragm spring of rotation carries out cutting magnetic line movement in high frequency magnetic field; The diaphragm spring that makes reaches the transformation temperature of material in time very short time, under transformation temperature, and diaphragm spring rapid shaping and cooling; Thereby reach the hardness and the metallographic structure of heat treatment requirements, reduced heating period, and short non-oxidation phenomenon of time; Need not the ambient oxidation protection, energy-saving effect is very obvious, simultaneously; High-frequency quenching can make the metallographic structure utmost point short period of time internal conversion of material, and the surface obtains superfine stealthy martensite, has improved the hardness of material surface; Reduce fragility, prolonged the life-span of diaphragm spring.
Description of drawings
Fig. 1 is the structural representation that the present invention presses the equipment of quenching.
Embodiment
As shown in Figure 1; Realize that the present invention presses the key of the method for quenching to be to press the equipment of quenching; The said pressure equipment of quenching comprises wheelwork 1, ruhmkorff coil 2, high frequency electric source generating unit 3, TP 4, intelligence controlling device 5; In order to carry out intellectuality control and comprehension management; Said wheelwork 1, said high frequency electric source generating unit 3, said TP 4 all are electrically connected with said intelligence controlling device 5, and said wheelwork 1 comprises motor and is arranged on the clamping device on the motor rotation axis that said clamping device is used to clamp diaphragm spring.
Principle of work of the present invention is: after diaphragm spring being fixed on the said wheelwork 1, rotated by the said wheelwork 1 of said intelligence controlling device 5 controls, simultaneously, control said high frequency electric source generating unit 3 200-250KH is provided
ZHigh-frequency current give said ruhmkorff coil 2, produce high frequency magnetic field, at this moment, the diaphragm spring of rotation carries out the motion of cutting magnetic line under said high frequency magnetic field; Thereby the generation inductive current makes diaphragm spring reach the transformation temperature of material in very short time, under transformation temperature; The diaphragm spring rapid shaping also cools off, thereby reaches the hardness and the metallographic structure of heat treatment requirements, has reduced heating period; And short non-oxidation phenomenon of time need not the ambient oxidation protection, and energy-saving effect is very obvious; Simultaneously, high-frequency quenching can make the metallographic structure utmost point short period of time internal conversion of material, and the surface obtains superfine stealthy martensite; Improve the hardness of material surface, reduced fragility, prolonged the life-span of diaphragm spring.
And the setting of said TP 4 is to press the result of use of quenching equipment in order further to improve; Improve the performance of diaphragm spring; What said TP 4 adopted is high frequency-infrared line TP, and the Temperature Feedback that said TP 4 will be gathered is in real time given said intelligence controlling device 5, the magneticstrength control of 5 pairs of high frequency electric sources of said intelligence controlling device; Matching Design through said ruhmkorff coil 2; Make the uniform induction electric current that magnetic field produces in diaphragm spring, critically control the heat-up time and the temperature curve of diaphragm spring, make the relative traditional technology of uniformity of hardness of diaphragm spring improve 400%.
