DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-6 This application is described in further detail.

[0034] The embodiment of the present application discloses a quenching induction device for double-side surfaces of a V-shaped roller cross linear guide.

[0035] Example 1 Reference Figure 1 , Figure 2 The quenching induction device for the double-side surface of the V-shaped roller cross linear guide includes an induction conductor 1 connected to an external power supply and a magnetic conductor 2 connected to the induction conductor 1. The induction conductor 1 in this embodiment includes a metal magnetic tube 11, which is a hollow copper tube. Both ends of the metal magnetic tube 11 are electrically connected to the positive pole and the cathode of the power supply respectively. The metal magnetic tube 11 is fixedly arranged on a frame 3, and the frame 3 is made of insulating material. The metal magnetic tube 11 forms a door-shaped structure for placing the guide rail 4 in the middle of the frame 3. The two sections of the metal magnetic tube 11 are insulated and separated by an insulating plate 12 to avoid short circuit.

[0036] Reference Figure 1The internal channel of the metal magnetic tube 11 is a water flow channel, and the openings at both ends are water inlets 14, which are arranged on the same side of the frame 3. Both ends of the metal magnetic tube 11 are provided with connection ends 13 for electrical connection. The metal magnetic tube 11 is connected to a water outlet pipe 15 at the top of the door-shaped structure. The water outlet pipe 15 is arranged vertically upward. The top outlet of the water outlet pipe 15 is a water outlet 16. The water inlet 14 and the water outlet 16 are both externally connected to the cooling circulation system to form a circulating flow of cooling water. The cooling water enters the water flow channel from both ends of the metal magnetic tube 11, and then flows back to the cooling circulation system from the water outlet 16 on the water outlet pipe 15, thereby reducing the flow distance of the cooling water in the metal magnetic tube 11, increasing the amount of cooling water for heat exchange with the metal magnetic tube 11, and improving the cooling effect of the metal magnetic tube 11.

[0037] Reference Figure 1 When the cooling water flowing through the water channel can generate heat exchange with the metal magnetic tube 11, the metal magnetic tube 11 is cooled. The magnetizer 2 is located at the bottom of the door-shaped structure, and each magnetizer 2 is opposite to the V-shaped raceway surface 41 of the guide rail 4. The frame 3 is provided with a cooling component 5, and the cooling component 5 corresponds to the magnetizer 2 one by one. The cooling component 5 is used for heat exchange with the magnetizer 2 to cool the magnetizer 2.

[0038] When the quenching induction device quenches the guide rail 4, the cooling water in the cooling circulation system enters the water flow channel from the water inlet 14, and then generates heat exchange with the metal magnetic tube 11 to cool the metal magnetic tube 11. The cooling component 5 cools the magnetizer 2. By cooling the inductive conductor 1 and the magnetizer 2, the temperature increase of the magnetizer 2 and the inductive conductor 1 under the action of the track heat radiation can be reduced, the decrease in magnetic permeability can be alleviated, and the track quenching effect of the quenching induction device can be improved.

[0039] Reference Figure 1 The magnetizer 2 in this embodiment is in a V-shaped structure that matches the V-shaped raceway surface 41. The V-shaped structure of the magnetizer 2 can improve the distance between the magnetizer 2 and the V-shaped track surface to be more uniform, and improve the uniformity of the quenching of the V-shaped raceway surface 41 by the cooling component 5. The magnetizer 2 includes a silicon steel sheet 21 and a mica sheet 22. The mica sheet 22 is located at both ends of the silicon steel sheet 21 and is opposite to the tips 42 at both ends of the V-shaped raceway surface 41. By utilizing the low magnetic permeability of the mica sheet 22, the phenomenon of overheating at the tip 42 on the guide rail 4, resulting in cracking and reduced performance, can be effectively avoided. The metal magnetizer tube 11 passes through the silicon steel sheet 21 and the mica sheet 22, and its bent return portion is below the magnetizer 2. The magnetism gathering function of the silicon steel sheet 21 is utilized to heat and quench the V-shaped raceway surface 41, and the cooling water in the metal magnetizer tube 11 is utilized to cool the magnetizer 2, thereby improving the cooling effect of the magnetizer 2.

[0040] Reference Figure 1The cooling assembly 5 in this embodiment includes a cooling water spray pipe 51, which is fixedly arranged on the frame 3. The water outlet 16 of the cooling water spray pipe 51 is directed toward the side of the magnetizer 2 away from the guide rail 4, and sprays cooling water toward the magnetizer 2. Spraying the back of the magnetizer 2 through the cooling water spray pipe 51 can, on the one hand, cool the magnetizer 2, and on the other hand, effectively prevent the cooling water from splashing onto the guide rail 4, thereby reducing the influence on the quenching of the guide rail 4.

[0041] The implementation principle of Example 1 is as follows: when the quenching induction device quenches the guide rail 4, the cooling water in the cooling circulation system enters the water flow channel from the water inlet 14, and then generates heat exchange with the metal magnetic tube 11 to cool the metal magnetic tube 11. The cooling water is sprayed onto the back of the magnetizer 2 through the cooling water spray pipe 51 for cooling. By cooling the inductive conductor 1 and the magnetizer 2, the temperature increase of the magnetizer 2 and the inductive conductor 1 under the action of the track heat radiation can be reduced, the decrease in magnetic permeability can be reduced, and the track quenching effect of the quenching induction device can be improved.

[0042] Example 2 Reference Figure 3 , Figure 4 The difference between this embodiment and the embodiment 1 is that a cooling rack 52 is slidably provided on the frame body 3, the cooling rack 52 corresponds to the magnetic conductor 2 one by one, and the cooling rack 52 is made of insulating and high temperature resistant material.

[0043] Reference Figure 5 , Figure 6 The cooling rack 52 of this embodiment includes a baffle 521, a water dividing plate 522 and a water guide plate 523. The baffle 521 is located at the two side edges of the magnetizer 2. One end of the two baffles 521 is fixedly connected by a connecting plate 524, and the other end is a V-shaped structure that cooperates with the V-surface on the back of the magnetizer 2, ensuring that the two baffles 521 are more closely fitted to the back of the magnetizer 2. A sliding rod 525 is fixedly provided on the connecting plate 524, and the sliding rod 525 is slidably penetrated on the frame 3. A telescopic spring 526 is sleeved on the sliding rod 525, and one end of the telescopic spring 526 is fixedly connected to the frame 3, and the other end is fixedly connected to the connecting plate 524. The telescopic spring 526 pushes the baffle 521 to fit the V-surface on the back of the magnetizer 2.

[0044] Reference Figure 5 , Figure 6The water dividing plate 522 is fixedly arranged between the two baffles 521, and the water dividing plate 522 is arranged to be inclined downward toward the magnetizer 2, so that the end of the water dividing plate 522 away from the magnetizer 2 is the highest end, and the end abutting against the magnetizer 2 is the lowest end. The water outlet 16 of the cooling water spray pipe 51 is located at the highest end of the water dividing plate 522. A plurality of water drop holes 5221 are provided on the water dividing plate 522. The number of the water drop holes 5221 in this embodiment is two, and the two water drop holes 5221 are arranged at intervals along the inclined direction of the water dividing plate 522. The number of water guide plates 523 in this embodiment is two, which is the same as the water holes 5221. The water guide plates 523 correspond to the water holes 5221 one by one. The two water guide plates 523 are arranged below the water dividing plate 522 with an interval between them. One end of each water guide plate 523 is fixedly connected to the bottom of the water dividing plate 522, and the other end can abut against the back side of the magnet 2 under the push of the telescopic spring 526. At the same time, the end of each water guide plate 523 abutting against the magnet 2 is located at a different height.

[0045] When cooling the magnet 2, the cooling water flows from the cooling water spray pipe 51 to the water dividing plate 522, and then the cooling water flows through different water holes 5221 and flows to the corresponding water guide plate 523 through the water holes 5221, and then the cooling water flows along the water dividing plate 522 and the water guide plate 523 to the magnet 2, and exchanges heat with the magnet 2 to complete the cooling of the magnet 2; the cooling water is guided by the water dividing plate 522 and the water guide plate 523, which can effectively avoid the splashing of cooling water caused by direct spraying of cooling water on the magnet 2, and at the same time, the cooling water is guided to the magnet 2 through different water guide plates 523, which can improve the cooling effect of the magnet 2.

[0046] Reference Figure 5 , Figure 6 The water divider plate 522 is provided with a drain pipe 527 arranged in the vertical direction. The drain pipe 527 passes through the water divider plate 522 and the two water guide plates 523 from top to bottom. The drain pipe 527 is provided with a drain hole 5271 on the water divider plate 522 and each water guide plate 523. The drain hole 5271 is higher than the end of the corresponding water guide plate 523 or the water divider plate 522 that is in contact with the magnet 2. In this way, a space is formed between the water guide plate 523 or the water divider plate 522 and the back of the magnet 2. The cooling water can stay in the space for a period of time, so as to fully cool the magnet 2 and make full use of the cooling water. The drain hole 5271 is arranged on the side of the drain pipe 527 facing the magnet 2, which effectively prevents the cooling water on the water divider plate 522 from being directly discharged through the drain hole 5271.

[0047] The cooling water gathered at the bottom of the water distribution plate 522 and each water guide plate 523 is discharged into the drain pipe 527 through the corresponding drain holes 5271, reducing the heat exchange of the cooling water after heat exchange to the lower layer of cooling water and improving the cooling effect of each layer of cooling water on the magnetizer 2.

[0048] Reference Figure 5 , Figure 6 A water receiving cylinder 528 is fixedly provided at the bottom of the two baffles 521, and the water outlet 16 of the drain pipe 527 is arranged above the water receiving cylinder 528. The water receiving cylinder 528 can be connected to the cooling circulation system through a pipeline to facilitate the circulation of cooling water.

[0049] The implementation principle of Example 2 is as follows: when cooling the magnetizer 2, the cooling water flows from the cooling water spray pipe 51 to the water distribution plate 522, and then the cooling water flows through different water holes 5221 and flows to the corresponding water guide plate 523 through the water holes 5221, and then the cooling water flows along the water distribution plate 522 and the water guide plate 523 to the magnetizer 2, and heat is exchanged with the magnetizer 2 to complete the cooling of the magnetizer 2; the cooling water is guided by the water distribution plate 522 and the water guide plate 523, which can effectively avoid the splashing of cooling water caused by direct spraying of cooling water on the magnetizer 2, and at the same time, the cooling water is guided to the magnetizer 2 through different water guide plates 523, which can improve the cooling effect of the magnetizer 2. The cooling water after heat exchange on the water distribution plate 522 and the water guide plate 523 enters the drain pipe 527 along the drain hole 5271, and then is guided to the water receiving cylinder 528 through the drain pipe 527.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
