Description

Technical Field

[0001] The utility model relates to the field of valve spring processing, in particular to a high-frequency induction heating continuous quenching device for valve springs. Background Art

[0002] Valve springs are used for the intake and exhaust valves of engines (such as automobile and truck engines). They are cylindrical and conical in shape. During the processing of valve springs, the surface of the valve springs needs to be quenched. Therefore, a quenching device is required to quench the valve springs.

[0003] According to a Chinese patent with publication number CN220887605U, a high-frequency induction heating continuous quenching device for valve springs is disclosed. The utility model is provided with an interval rotating turntable structure on one side of the heating turntable, so that the valve spring workpiece can be fully heated and quenched, which can reduce the generation of defective products, and personnel can take out and put in the workpiece at intervals; a quenching liquid reflux structure is provided on the other side of the heating turntable, and the liquid leaking after the quenching liquid is sprayed on the workpiece falls into the reflux tank, reducing the waste of quenching liquid.

[0004] In response to the above-mentioned disclosed patent content, a liquid spray assembly is provided. When the heated valve spring rotates to one side of the liquid spray assembly, the pump body on the liquid spray assembly can transport the quenching liquid to the nozzle, and then spray it onto the valve spring through the nozzle, so as to cool the valve spring and achieve the purpose of quenching. However, after the quenching liquid is sprayed onto the valve spring, part of the quenching liquid will reflux through the reflux structure, and part of the quenching liquid will splash and splash onto other parts of the device, making it difficult to completely recover the quenching liquid, thereby causing waste of quenching liquid. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a valve spring high-frequency induction heating continuous quenching device to solve the technical problem of quenching liquid splashing and causing waste when the quenching liquid is sprayed onto the valve spring through the spray component.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-frequency induction heating continuous quenching device for valve springs, comprising a base plate, a water pool is installed on the top of the base plate, a fixed plate is provided on the top of the water pool, and a rotating shaft is connected to the fixed plate through a bearing, a heat conduction disk is installed at one end of the rotating shaft, and a plurality of heat conduction blocks are installed on the outer wall of the heat conduction disk, a heat conduction rod is installed on the outer surface of the heat conduction block, and a groove is provided inside the heat conduction rod, a spring is installed inside the groove, and one end of the spring is connected to a limit column extending to the outside of the heat conduction rod.

[0007] By adopting the above technical solution, when the heat conducting plate rotates, it will drive the heat conducting block to rotate, and then drive the heat conducting rod and the valve spring to rotate. When the heat conducting block is transferred into the quenching liquid, the valve spring can be quenched.

[0008] Furthermore, a high-frequency heating turntable is installed on the outer surface of the heat-conducting plate, and a protective cover is provided on the high-frequency heating turntable.

[0009] By adopting the above technical solution, the protective cover can shield and protect the high-frequency heating turntable, preventing the quenching liquid from flowing to the surface of the high-frequency heating turntable, thereby increasing the service life of the high-frequency heating turntable.

[0010] Furthermore, a driving motor is provided on the top of the water pool, and an output end of the driving motor is connected to a driving bevel gear.

[0011] By adopting the above technical solution, when the heat conducting plate needs to be rotated, the driving motor can be started, and the driving motor can drive the active bevel gear to rotate, thereby driving the driven bevel gear to rotate.

[0012] Furthermore, a driven bevel gear is sleeved on the outer wall of the rotating shaft, and the driving bevel gear is meshed with the driven bevel gear.

[0013] By adopting the above technical solution, when the active bevel gear rotates, it drives the driven bevel gear to rotate, and the driven bevel gear drives the rotating shaft to rotate.

[0014] Furthermore, a support column is provided on the top of the water pool, and a support ring is installed on the top of the support column.

[0015] By adopting the above technical solution, the arrangement of the support column and the support ring can support the rotating shaft and improve the stability of the rotating shaft when it rotates.

[0016] Furthermore, a drain pipe is installed below one side of the pool, and a drain valve is installed on the drain pipe.

[0017] By adopting the above technical solution, when the quenching liquid needs to be discharged, the drain valve can be opened so that the quenching liquid can be discharged through the drain pipe.

[0018] Furthermore, a sealing ring is provided between the limiting column and the heat conducting rod.

[0019] By adopting the above technical solution, the provision of the sealing ring can improve the sealing between the heat-conducting rod and the limiting column, and prevent the quenching liquid from penetrating into the groove.

[0020] Furthermore, the limiting column is slidably connected to the groove, and the spring is made of stainless steel.

[0021] By adopting the above technical solution, the limiting column can be moved into the groove and squeeze the spring, so that the spring is compressed, which facilitates the subsequent pushing of the limiting column to reset and move.

[0022] Furthermore, the outer wall of the heat-conducting rod is sleeved with a valve spring, and the limiting column is located on the outer surface of the valve spring.

[0023] By adopting the above technical solution, the valve spring can be sleeved on the heat-conducting rod, which is convenient for subsequent transfer into the quenching liquid.

[0024] Furthermore, a plurality of the heat-conducting blocks are distributed on the outer wall of the heat-conducting plate in a ring array, and one of the heat-conducting blocks is located at the lower part of the pool.

[0025] By adopting the above technical solution, the valve spring on one heat-conducting rod can be immersed in the quenching liquid, while the valve springs on other heat-conducting rods will not be immersed in the quenching liquid.

[0026] In summary, the utility model mainly has the following beneficial effects:

[0027] The utility model is provided with a heat conducting block, a rotating shaft, a heat conducting plate, a groove, a spring and a limiting column. When the heat conducting plate rotates, it drives the heat conducting block to rotate, and then drives the heat conducting rod and the valve spring to rotate. When the heat conducting block is transferred into the quenching liquid, the valve spring can be quenched. At this time, the driving motor stops driving the heat conducting plate to rotate, and the heat conducting plate is stopped for 30 seconds. Then the user can press the limiting column on the upper left heat conducting rod, so that the limiting column moves into the groove and no longer limits the valve spring. At this time, the valve spring on the heat conducting rod can be taken out, and then the quenched valve spring is sleeved on the heat conducting rod, and the limiting column is loosened, so that the limiting column is reset and blocks the valve. The valve spring is prevented from falling off the heat-conducting rod. In this way, the valve spring can be completely immersed in the quenching liquid for quenching treatment, thereby improving the quenching effect on the valve spring and avoiding that part of the valve spring cannot contact with the quenching liquid. At the same time, this method does not need to add a pump body to spray the quenching liquid onto the valve spring, thereby saving energy, and does not need to recycle the quenching liquid. It also avoids the waste caused by splashing the quenching liquid by the spraying method. Moreover, since the heat-conducting plate is in a vertical state, the quenching liquid remaining on the valve spring or the heat-conducting rod will drip downward by itself, thereby reducing the residual amount of quenching liquid attached to the heat-conducting plate, the heat-conducting rod and the valve spring.

The setting of the sealing ring 22 can improve the sealing between the heat conducting rod 9 and the limiting column 21 , and prevent the quenching liquid from penetrating into the groove 19 .

[0047] The working principle of the utility model is as follows: first, the staff installs the device and turns on the power supply, adds the quenching liquid into the water pool 2, then presses the limit column 21, so that the limit column 21 moves into the groove 19, and then the valve spring 10 is sleeved on the heat-conducting rod 9, and then the limit column 21 is loosened, so that the limit column 21 is reset and moves to limit the valve spring 10, and then the high-frequency heating turntable 7 is started, and the high-frequency heating turntable 7 can be heated, and the valve spring 10 is heated through the heat-conducting block 8 and the heat-conducting rod 9, and then the driving motor 13 is started, and the driving motor 13 can drive the active bevel gear 14 to rotate, and then the drive motor 13 is driven to drive the active bevel gear 14 to rotate.
