At the same time, it needs to achieve high-precision linear motion under high load conditions, and has high requirements for strength. The quenching step is very important for the slider. The original quenching process puts the linear guide rail and the slider as a whole into a box furnace for quenching. This overall quenching has a large deformation amount, requires a large machining allowance for the reserved post-processing procedures, has a large machining difficulty, a long machining time, a relatively low machining efficiency, and a high machining cost, which is not conducive to long-term processing. Summary of the Invention

Detailed Embodiment

[0021] The following further describes the present utility model with reference to the drawings.

[0022] As Figure 1 shown, the inductor base includes the fixed plate 1, the first connecting pipe 2.1, and the second connecting pipe 2.2. There are two fixed plates 1, and the two fixed plates 1 are arranged oppositely. The first connecting pipe 2.1 and the second connecting pipe 2.2 are respectively arranged on the outer sides of the two fixed plates 1. The tops of the first connecting pipe 2.1 and the second connecting pipe 2.2 are respectively connected to the bottom of the slider induction coil 8. The magnetic conductors 7 are respectively embedded on both sides of the top of the slider induction coil 8. The magnetic conductors 7 are arranged on the top of the slider induction coil 8 to facilitate the quenching work. As Figure 7 shown, the slider 6 is arranged at the top end of the slider induction coil 8. As Figure 6 shown, the top of the slider induction coil 8 is provided with a groove 10 that matches the inner notch of the slider 6. The groove 10 of the slider induction coil 8 can fit the shape of the inner notch of the slider 6 to enable the slider 6 to be fully quenched.

[0023] The second connecting pipe 2.2 is provided with a water sprayer connecting plate 3 on its side. The second connecting pipe 2.2 is connected to the water sprayer 13 through the water sprayer connecting plate 3. The inside of the slider induction coil 8 is hollow.

[0024] The structure of the water sprayer 13 is L-shaped and its inside is hollow. The side of the water sprayer 13 is provided with a screw 16 that cooperates with the water sprayer connecting plate 3. One end of the water sprayer 13 is provided with a water inlet pipe 14, and the other end of the water sprayer 13 is provided with a number of water outlet nozzles 15. The water sprayer 13 is used for quenching and cooling, mainly for cooling the main slider 6.

[0025] Each of the bottoms of the two fixing plates 1 is provided with a water inlet and outlet hole 9. Water flow is introduced into the water inlet and outlet hole 9 on one side, and the water flow flows out from the water inlet and outlet hole 9 on the other side. The water flow is used for cooling the entire inductor to prevent the slider induction coil 8 from being burned out due to excessive output power.

[0026] An insulating plate 11 is provided between the fixing plates 1. The insulating plate 11 is made of a polytetrafluoroethylene plate. The polytetrafluoroethylene plate has high stability and is a Class C insulating material. It can withstand high temperatures up to 220 °C and is widely used in insulation work for high-temperature processing such as quenching.

[0027] The fixing plate 1 and the insulating plate 11 are connected by bolts 4 and nuts 5. The bolts 4 are nylon bolts, and the nuts 5 are brass nuts. The nylon bolts have good insulation performance, while the brass nuts have good heat conduction effects.

[0028] The fixing plate 1 and the insulating plate 11 are provided with through holes 12 for the bolts 4 to pass through.

[0029] The specific operation process of the present utility model is as follows. The fixing plates 1 on both sides fix the insulating plate 11 in the middle. The first connecting pipe 2.1 and the connecting pipe 2.2 at the upper end of the fixing block 1 and the slider induction coil 8 form a water circuit. High-pressure water is introduced through the water inlet and outlet hole 9 on one side of the inductor base, flows through the first connecting pipe 2.1, the slider induction coil 8 and the connecting pipe 2.2, and flows back to the water tank from the other water inlet and outlet hole 9 of the inductor base. The slider induction coil 8 is an integrated pipeline and can be approximately regarded as an induction coil in the shape of a square or a ring. Due to the influence of the circular ring effect inside the slider induction coil 8, a large current density distribution is concentrated inside the slider induction coil 8. The magnetic conductors 7 connected to both sides of the slider induction coil 8 weaken the circular ring effect and increase the notch effect, so that both sides of the notch of the U-shaped groove 10 of the slider inductor 8 have higher quenching efficiency. The connecting pipe 2.2 is connected to the L-shaped water sprayer 13 on the side. The water outlet nozzles 15 of the water sprayer 13 are arranged below the slider induction coil 8, as Figure 7As shown in the figure, during the quenching process, the fixed slider 6 is fixed, and the slider induction coil 8 is aligned with the inner notch of the slider 6, so that the inner notch of the slider 6 wraps around the periphery of the slider induction coil 8. The quenching inductor is moved from bottom to top. The water inlet pipe 14 is externally connected to the water inlet, and the water flows along the water sprayer 13. The water sprays from the water outlet nozzle 15 against the groove 10 of the slider induction coil 8 for cooling, while the slider induction coil 8 is energized and heated by itself, so as to achieve the quenching function. In addition, high-pressure water is connected through an inlet and outlet 9 at the base of the induction coil, and after passing through the connecting pipe 1 2.1, the slider induction coil 8, and the connecting pipe 2 2.2, it flows out from another inlet and outlet 9 and returns to the water tank, realizing the cooling of the slider induction coil 8 and preventing the slider induction coil 8 from being scrapped due to excessive temperature.
