Description

Technical Field

[0001] The present application relates to the technical field of high-frequency quenching of wheel-type parts surfaces, and in particular to a special auxiliary device for high-frequency quenching of wheel-type parts surfaces. Background Art

[0002] Medium frequency quenching is to put the metal part in an induction coil, pass alternating current through the induction coil, generate an alternating electromagnetic field, and induce an alternating current in the metal part. Due to the skin effect, the current is mainly concentrated on the surface of the metal part, so the surface temperature is the highest. Water spray cooling or other cooling is followed under the induction coil. Since heating and cooling are mainly concentrated on the surface, the surface modification is obvious, while the internal modification is basically non-existent, which can have a very special heat treatment effect. The outer peripheral surface of wheel parts needs to be treated by medium frequency quenching during the production and processing process.

[0003] In the prior art, the following is usually used: Figure 1 to Figure 2 The structure shown in the figure performs medium frequency quenching treatment on wheel parts. Specifically, the wheel parts 10 are placed on the rotating bracket 40, the wheel parts 10 are driven to rotate, and then the medium frequency induction heating head 20 and the cooling nozzle 30 are used to heat and spray cooling water for quenching. The wheel parts 10 rotate one circle to complete the quenching. However, in this method, in order to make the wheel parts 10 have two sides ( Figure 2 In order to ensure uniform medium frequency heating (upper and lower sides) and avoid uneven heating resulting in uneven quenching effect (hardness after quenching) on ​​both sides, the medium frequency induction heating head 20 needs to be placed in the center. For wheel parts 10 of different specifications, their widths are different, which requires adjusting the height of the medium frequency induction heating head 20 or the height of the rotating bracket 40. Regarding adjusting the height of the medium frequency induction heating head 20, due to the high temperature on the medium frequency induction heating head 20, there is a certain safety risk in manually adjusting the height, and different height specifications of pads are required for wheel parts 10 of different specifications to adjust the height of the medium frequency induction heating head 20, resulting in many types of pads and high replacement frequency; regarding adjusting the height of the rotating bracket 40, currently, a rotating bracket 40 with a fixed height is usually designed for each specification of wheel parts 10, which cannot be universal, resulting in many types of rotating brackets 40 and high replacement frequency.

[0004] At the same time, when the cooling nozzle 30 sprays cooling water for cooling, the cooling water sprayed onto the wheel-like parts 10 flows downward, the cooling time on the upper side is short, and the cooling time on the lower side is long, resulting in uneven cooling, which will also cause the quenching effect (hardness after quenching) to be uneven on both sides.

The present application provides a special auxiliary device for high-frequency quenching of the surface of wheel-like parts.

At the same time, through the rotating shaft and the supporting wheel group, the wheel parts are vertically arranged, and the cooling water sprayed from the cooling nozzle flows downward evenly along the outer peripheral surface under the action of gravity, and the cooling speed on both sides of the wheel-like parts in the width direction is consistent, thereby solving the above-mentioned problems in the prior art.

[0027] Please refer to Figure 1 and Figure 6 The embodiment of the present application discloses a special auxiliary device for high-frequency quenching of wheel parts (hereinafter referred to as the auxiliary device), which is used for high-frequency quenching tooling of wheel parts 10. When high-frequency quenching of wheel parts 10, the wheel parts 10 need to be installed on the auxiliary device first, and then the position and height of the auxiliary device need to be moved and adjusted to align the outer peripheral surface of the wheel parts 10 with the medium-frequency induction heating head 20 and the cooling nozzle 30 (such as Figure 4 As shown in the figure), the wheel-like part 10 rotates one circle to complete the quenching. The auxiliary device disclosed in the present application includes a base frame 100, a first lifting bracket 200, a supporting wheel group 300, a driving mechanism 400, a rotating shaft 500 and a clamping baffle 600, wherein:

[0028] A universal wheel 110 is provided at the bottom of the base frame 100 for moving the auxiliary device to adjust the position of the auxiliary device, thereby adjusting the position of the wheel-like part 10, so as to match the outer peripheral surface of the wheel-like part 10 with the medium frequency induction heating head 20 and the cooling nozzle 30, and then align the outer peripheral surface of the wheel-like part 10 with the medium frequency induction heating head 20 and the cooling nozzle 30 by adjusting the height of the auxiliary device. The first lifting bracket 200 is arranged at one end of the upper side of the base frame 100, the driving mechanism 400 is arranged on the first lifting bracket 200, and the rotating shaft 500 is connected to the driving mechanism 400. By adjusting the lifting height of the first lifting bracket 200, the height of the driving mechanism 400 is adjusted, thereby adjusting the height of the rotating shaft 500. When the wheel-like parts 10 are high-frequency quenched, the wheel-like parts 10 need to be installed on the rotating shaft 500 first, and then the height of the rotating shaft 500 is adjusted by the first lifting bracket 200, thereby adjusting the height of the wheel-like parts 10. After adjusting to a suitable position, the driving mechanism 400 rotates to drive the rotating shaft 500 to rotate, and the rotating shaft 500 can drive the wheel-like parts 10 to rotate. The wheel-like parts 10 rotate one circle to complete the quenching.

[0029] Specifically, the structure of the rotating shaft 500 driving the wheel-like component 10 to rotate is as follows: one end of the rotating shaft 500 connected to the driving mechanism 400 is provided with a flange 510, and the other end is provided with an external thread. The clamping baffle 600 can be matched with the external thread to make the distance between the clamping baffle 600 and the flange 510 adjustable. The distance between the clamping baffle 600 and the flange 510 is adjusted by the number of turns of tightening the clamping baffle 600 on the external thread. First, the wheel-like component 10 is installed on the rotating shaft 500, and the wheel-like component 10 is abutted against the flange 510. , and then the clamping baffle 600 is screwed onto the external thread until the clamping baffle 600 is pressed against the wheel-like part 10, so that the wheel-like part 10 is clamped by the flange 510 and the clamping baffle 600. In this way, when the rotating shaft 500 rotates, the flange 510 and the clamping baffle 600 rotate with the rotating shaft 500. Since the flange 510 and the clamping baffle 600 clamp the wheel-like part 10, the wheel-like part 10 will also rotate under the clamping action of the flange 510 and the clamping baffle 600, thereby achieving the purpose of the rotating shaft 500 driving the wheel-like part 10 to rotate. At the same time, since the distance between the clamping baffle 600 and the flange 510 is adjustable, it can be applied to wheel-like parts 10 of different width specifications, that is, wheel-like parts 10 of different width specifications can be clamped by the flange 510 and the clamping baffle 600.

[0030] Since the weight of the wheel-like parts 10 is generally large, if the wheel-like parts 10 are directly installed on the rotating shaft 500, the weight of the wheel-like parts 10 will be borne entirely by the rotating shaft 500. Since the rotating shaft 500 is cantilevered, it is easy to cause the rotating shaft 500 to bend, bend, tilt, or even fail to support the wheel-like parts 10. In severe cases, the connection between the rotating shaft 500 and the driving mechanism 400 will be directly torn off. At the same time, this will also cause the power output shaft of the driving mechanism 400 to be subjected to radial force and torque, which is easy to damage the driving mechanism 400. Therefore, the auxiliary device in the present application is specially provided with a supporting wheel group 300, and the supporting wheel group 300 includes two supporting sub-wheel groups, each of which includes a second lifting bracket 310 and two supporting wheels 320. In the direction of the rotation axis of the rotating shaft 500, the second lifting bracket 310 is slidably arranged on the base frame 100, and the two supporting wheels 320 are rotatably arranged on the second lifting bracket 310, and are spaced apart in a direction perpendicular to the rotation axis of the rotating shaft 500, such as Figure 4 In the embodiment, two support wheels 320 are used to support the wheel-like parts 10, one on the left and one on the right, and the rotation axis of the support wheels 320 is parallel to the rotation axis of the rotating shaft 500. First, the second lifting bracket 310 is lifted and lowered to adjust the height of the support wheels 320, so that the support wheels 320 just support the wheel-like parts 10, so that the wheel-like parts 10 and the rotating shaft 500 are concentric. When the wheel-like parts 10 rotate, the support wheels 320 rotate along with them. At the same time, since the second lifting bracket 310 is slidably arranged on the bottom frame 100 in the direction of the rotation axis of the rotating shaft 500, this arrangement is to enable the two support sub-wheel groups to adapt to wheel-like parts 10 of different widths. The positions of the two support sub-wheel groups are adjusted according to the specific width of the wheel-like parts 10, so that the two support sub-wheel groups can support the wheel-like parts 10 and are suitable for wheel-like parts 10 of different widths, so that the support wheel group 300 can be adjusted up and down and left and right ( Figure 5 ) can be adjusted to meet the needs of wheel parts of different specifications 10.

[0031] With the support of the support wheel 320, the rotating shaft 500 is basically not subjected to force and only serves to rotate to drive the wheel-like parts 10 to rotate. In this way, it is possible to avoid the weight of the wheel-like parts 10 being entirely borne by the rotating shaft 500, which would cause the rotating shaft 500 to bend, bend, tilt, or even be unable to support the wheel-like parts 10. In severe cases, the connection between the rotating shaft 500 and the driving mechanism 400 will be directly torn apart. At the same time, it is also possible to avoid the power output shaft of the driving mechanism 400 being subjected to radial force and torque and damaging the driving mechanism 400.

[0032] In the specific use process, the wheel-like component 10 is first lifted by the lifting mechanism, and the center hole of the wheel-like component 10 is passed through the rotating shaft 500, and the wheel-like component 10 is made to abut against the flange 510. At this time, the lifting mechanism continues to lift to prevent the rotating shaft 500 from bearing the weight alone, and then adjusts the positions of the two supporting sub-wheel assemblies (the second lifting bracket 310 is slidably set on the bottom frame 100, Figure 5 The left and right adjustment in the figure) makes the positions of the two supporting sub-wheel groups located below the wheel-like parts 10, and then adjusts the height of the supporting wheel 320 by the second lifting bracket 310, so that the supporting wheel 320 supports the wheel-like parts 10, and then screws the clamping baffle 600 onto the external thread until the clamping baffle 600 is pressed against the wheel-like parts 10, so as to clamp the wheel-like parts 10 through the retaining flange 510 and the clamping baffle 600. At this time, the lifting mechanism is removed. Under the support of the supporting wheel 320, the rotating shaft 500 is basically not subjected to force, and then the auxiliary device and the wheel-like parts 10 are moved as a whole by the universal wheel 110, so as to match the outer peripheral surface of the wheel-like parts 10 with the medium frequency induction heating head 20 and the cooling nozzle 30, that is, the medium frequency induction heating head 20 is centrally arranged. At this time, the position of the medium frequency induction heating head 20 may be located on the lower side of the wheel-like parts 10, and is not in a position as shown in the figure. Figure 4 The position shown in the figure needs further adjustment. At this time, only the height of the wheel-like part 10 needs to be adjusted. Specifically, the heights of the first lifting bracket 200 and the second lifting bracket 310 are adjusted at the same time. It should be noted that the heights are adjusted at the same time to adjust the height of the wheel-like part 10 so that the outer peripheral surface of the wheel-like part 10 is aligned with the medium frequency induction heating head 20 and the cooling nozzle 30, so that the medium frequency induction heating head 20 and the cooling nozzle 30 are located as shown in the figure. Figure 4 The position shown is then subjected to high-frequency quenching, and the driving mechanism 400 is started. Under the clamping action of the retaining flange 510 and the clamping baffle 600, the wheel-like part 10 will also rotate, and the wheel-like part 10 completes quenching after one rotation.

[0033] In a special auxiliary device for high-frequency quenching of the surface of wheel-like parts disclosed in an embodiment of the present application, the height of the wheel-like part 10 can be adjusted by the first lifting bracket 200 and the supporting wheel group 300, and the height and position of the wheel-like part 10 can be adjusted by the cooperation of the universal wheel 110, so that the wheel-like part 10 can be aligned with the medium-frequency induction heating head 20, so that the medium-frequency induction heating head 20 is placed in the center, so that the medium-frequency heating of both sides of the wheel-like part 10 in the width direction is uniform, and uneven heating causes uneven quenching effect on both sides. Therefore, there is no need to adjust the height of the medium-frequency induction heating head 20, avoid manual adjustment and safety risks, and solve the problem of many types of pads and high replacement frequency, and the first lifting bracket 200 is lifted and lowered, and the supporting wheel group 300 is adjusted up and down, left and right ( Figure 5) adjustment, and because the distance between the clamping baffle 600 and the retaining flange 510 is adjustable, the auxiliary device in the present application can be applied to wheel parts 10 of different specifications, so that the auxiliary device has universality, and there is no need to design a rotating bracket 40 with a fixed height for each specification of wheel parts 10, thereby avoiding a large number of types of rotating brackets 40 and a high replacement frequency. At the same time, through the rotating shaft 500 and the supporting wheel group 300, the rotation axis of the wheel part 10 is horizontal, that is, the wheel part 10 is vertically arranged, such as Figure 4 As described above, unlike the horizontal setting in the prior art, the cooling water sprayed by the cooling nozzle 30 flows downward evenly along the outer peripheral surface under the action of gravity, the cooling speed on both sides of the wheel-like parts 10 in the width direction is consistent, and the quenching hardness is uniform, thereby improving the quality of the wheel-like parts 10.

[0034] At the same time, the cooling water flowing evenly downward along the outer peripheral surface can continue to stay on the outer peripheral surface of the wheel-like part 10, continue to cool the outer peripheral surface of the wheel-like part 10, extend the cooling contact time, improve the cooling effect, and thus improve the quenching effect.

[0035] In order to ensure that the retaining flange 510 and the clamping baffle 600 clamp the wheel-like parts 10, optionally, the auxiliary device disclosed in the present application can also include a locking nut 700. The locking nut 700 can cooperate with the external thread to prevent loosening through the locking nut 700, and can provide a certain clamping force through the clamping baffle 600 to clamp the wheel-like parts 10 to avoid the lack of clamping, which makes it difficult for the rotating shaft 500 to drive the wheel-like parts 10 to rotate, thereby improving the stability and reliability of the rotating shaft 500 driving the wheel-like parts 10 to rotate.

[0036] Furthermore, the side of the clamping baffle 600 facing the side flange 510 and the side of the side flange 510 facing the clamping baffle 600 are both provided with anti-slip grooves, so that when the side flange 510 and the clamping baffle 600 clamp the wheel-like parts 10, it is possible to prevent the wheel-like parts 10 from sliding relative to the side flange 510 and the clamping baffle 600, which would make it difficult for the wheel-like parts 10 to be driven to rotate. The friction force is increased by the anti-slip grooves, and the side flange 510 and the clamping baffle 600 can drive the wheel-like parts 10 to rotate under a smaller clamping force.

[0037] In order to prevent the thread fit between the clamping baffle 600 and the external thread from loosening during the rotational quenching of the wheel-like part 10, optionally, the locking rotation direction of the clamping baffle 600 on the external thread is opposite to the rotation direction of the rotating shaft 500. With this arrangement, the friction force applied to the clamping baffle 600 by the rotation of the wheel-like part 10 is the same as the locking rotation direction of the clamping baffle 600 on the external thread. Therefore, during the rotational quenching of the wheel-like part 10, the clamping baffle 600 can only be tightened, thereby preventing the thread fit from loosening, thereby ensuring that the flange flange 510 and the clamping baffle 600 clamp the wheel-like part 10, and further ensuring the stability of the rotation of the wheel-like part 10 driven by the rotating shaft 500, thereby preventing the wheel-like part 10 from being unable to rotate for quenching due to loose thread fit during the rotational quenching of the wheel-like part 10.

[0038] Preferably, the second lifting bracket 310 includes two supporting vertical frames 311, a horizontal frame 312 and two lifting vertical frames 313. The two supporting vertical frames 311 are spaced apart in a direction perpendicular to the rotation axis of the rotating shaft 500 and are both slidably arranged on the bottom frame 100. The horizontal frame 312 is slidably arranged with the two supporting vertical frames 311. The two lifting vertical frames 313 are respectively arranged at both ends of the horizontal frame 312. The two supporting wheels 320 are respectively rotatably arranged at the upper ends of the two lifting vertical frames 313, so that the second lifting bracket 310 can be adjusted up and down and left and right ( Figure 5 ) to meet the needs of wheel parts 10 of different specifications. The second lifting bracket 310 of this structure is simple in structure and reliable in operation.

[0039] Since the temperature of the outer peripheral surface of the wheel-like component 10 after quenching is still relatively high, in order to avoid burning the support wheel 320 made of general rubber material, the support wheel 320 can be optionally a high temperature resistant support wheel.

[0040] Preferably, when the wheel-like part 10 is arranged on the rotating shaft 500, the medium frequency induction heating head 20 and the cooling nozzle 30 are arranged in sequence on the side of the wheel-like part 10 that rotates downward in the rotation direction, and the medium frequency induction heating head 20 and the cooling nozzle 30 are both located on the upper half of the wheel-like part 10, that is, the wheel-like part 10, the medium frequency induction heating head 20 and the cooling nozzle 30 are in the following manner: Figure 4 The position shown is arranged in this way so that the cooling water that flows evenly downward along the outer peripheral surface can continue to stay on the outer peripheral surface of the wheel-like part 10, continue to cool the outer peripheral surface of the wheel-like part 10, extend the cooling contact time, improve the cooling effect, and thus improve the quenching effect.

[0041] In the present application, the rotating shaft 500 is connected to the driving mechanism 400 via a coupling to facilitate replacement of a damaged rotating shaft 500 .

[0042] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
