[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1: This utility model provides the following... Figure 1 and Figure 2 The high-frequency quenching equipment for nuts shown includes a processing table 1 and a support frame 6. A quenching mechanism is provided at the top of the processing table 1 and at the end near the back. The support frame 6 is provided at the top of the processing table 1 and at the end near the front. An installation opening is opened in the middle area of ​​the front of the processing table 1, and the support frame 6 is fixedly installed in the installation opening.

[0031] Specifically, the quenching mechanism includes:

[0032] A high-frequency induction heating machine 2 is installed at the top of the processing table 1. The output end of the high-frequency induction heating machine 2 is electrically connected to an induction coil 4. The high-frequency induction heating machine 2 is a device that uses the principle of high-frequency electromagnetic field for heating. Its working principle is to generate eddy currents in the conductor through high-frequency current, thereby rapidly heating the material in a short time. In this scheme, the induction coil 4 is used as the external output end. Therefore, eddy currents are generated in the area to be fitted in the middle of the induction coil 4. After the eddy currents are generated on the surface of the nut inserted in the induction coil 4, it is rapidly heated, thereby completing the rapid heating and quenching.

[0033] The digital display time relay 3 is located at the top of the high-frequency induction heater 2, and its receiving end is electrically connected to the control end of the high-frequency induction heater 2. By setting the digital display time relay 3, the output time of the high-frequency induction heater 2 can be controlled, and the output time of the high-frequency induction heater 2 can be viewed through the digital display time relay 3.

[0034] Example 2: This utility model provides the following... Figure 3 and Figure 4 The placement mechanism and unloading component shown are applied to a high-frequency quenching equipment for nuts in Embodiment 1. The placement mechanism is vertically connected to the middle of the support frame 6. The placement mechanism is used to place the nuts to be quenched. The placement mechanism includes a placement component and a traction component. The placement component is located on the top of the traction component. The placement component is inserted and exposed at the top of the support frame 6. The traction component is inserted and exposed at the bottom of the support frame 6. The induction coil 4 is sleeved on the outer wall of the placement component.

[0035] The blanking part is set at the top of the processing table 1 and is sleeved on the exposed end of the placement part. The blanking part is used to blank the quenched nut when the placement part moves down.

[0036] Specifically, the placement components include:

[0037] The support rod 701 is inserted and connected to the top of the support frame 6 at its bottom. The bottom end of the support rod 701 is fixedly connected to the top end of the traction component. The unloading component is sleeved on the outer wall of the support rod 701.

[0038] Sleeve rod 702 is fixedly installed at the top of support rod 701 and is used to sleeve the nut to be quenched.

[0039] It should be noted that the outer diameter of the sleeve rod 702 is smaller than the outer diameter of the support rod 701. This way, the nut sleeved on the outer wall of the sleeve rod 702 will be supported on the top of the support rod 701, thereby ensuring that the nut can be inserted into the middle of the induction coil 4 under the support of the support rod 701.

[0040] Specifically, the unloading component includes an unloading guide plate 5, which is fixedly connected to the top of the processing table 1, and the top of the unloading guide plate 5 is inclined.

[0041] Furthermore, a feeding groove 501 is provided at the top of the feeding guide plate 5, and a slot is provided at one end of the feeding groove 501, with the support rod 701 inserted and connected in the slot.

[0042] It should be noted that the end of the feeding guide plate 5 that is sleeved on the outer wall of the support rod 701 is the highest point. In this way, as the support rod 701 moves down, the nut set at the top of the support rod 701 is lifted by the feeding guide plate 5 under the scraping of the side wall of the bayonet. After the sleeve rod 702 slides to the bottom of the feeding guide plate 5, the nut is completely placed at the top of the feeding guide plate 5 and slides down along the feeding groove 501.

[0043] Specifically, the traction components include:

[0044] Pull-down rod 7, the top of pull-down rod 7 slides through the support frame 6 in the vertical direction, and the top of pull-down rod 7 is fixedly connected to the bottom of support rod 701;

[0045] Pull-down block 704 is fixedly connected to the bottom end of pull-down rod 7.

[0046] Furthermore, a support groove is provided on the side wall at the intersection of the support frame 6 and the pull rod 7, and a support slider 703 is fixedly connected to the side wall of the pull rod 7, and the support slider 703 is slidably inserted into the support groove.

[0047] Furthermore, a top support spring 8 is provided inside the support groove, and the top support spring 8 is located at the bottom end of the support slider 703.

[0048] It should be noted that when unloading the nut after quenching, first pull down the pull block 704. The pull block 704 drives the pull rod 7 and the support slider 703 to move down synchronously. Under the traction of the pull rod 7, the support rod 701 and the sleeve rod 702 move down synchronously. At this time, the nut is scraped off by the unloading guide plate 5 and then rolled off along the unloading groove 501. Then, the pull on the pull block 704 is slowly released until the top of the sleeve rod 702 passes through the top of the unloading guide plate 5. Then, the next nut to be quenched is sleeved on the top of the sleeve rod 702. The pull on the pull block 704 is completely released. At this time, the top support spring 8 pushes the support slider 703 upward. Under the drive of the support slider 703, the pull rod 7, the support rod 701 and the sleeve rod 702 drive the sleeved nut to move upward. This places the nut on top of the induction coil 4 for a new round of quenching.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
