Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of quenching processing, in particular to a double-sided quenching inductor for linear guide rails. Background Art
[0002] Linear guide rails are mostly used in straight reciprocating motion occasions and can bear a certain torque, enabling high-precision linear motion under high loads. Most machine tools in many precision machining fields use high-precision linear guide rails as machine tool guide rails, which can ensure the machining accuracy of the machine tool. Not only in the machining field, but also in many automated production lines, the application range is wider. However, the existing linear guide rails often use single-sided quenching, which easily leads to uneven stress distribution on both sides and excessive deformation. Summary of the Invention
[0003] In order to overcome the deficiencies of the prior art, the utility model provides a double-sided quenching inductor for linear guide rails, which realizes simultaneous quenching on both sides of the linear guide rail. A secondary inductor is designed on one side to realize simultaneous induction quenching on both sides of the linear guide rail.
[0004] To achieve the above object, a double-sided quenching inductor for linear guide rails is designed, including an inductor base, a magnetic conductor, and a linear guide rail. The inductor base includes a fixing plate and a connecting pipe. There are two fixing plates, which are arranged opposite to each other. Connecting pipes are respectively arranged on the outer sides of the fixing plates. One end of a multi-bent induction coil is connected to each of the two connecting pipes. After being bent multiple times, the multi-bent induction coil successively forms a first-layer guide rail induction coil and a second-layer guide rail induction coil. Two first magnetic conductors are connected to the lower surface of the first-layer guide rail induction coil, and two second magnetic conductors are connected to the upper surface of the second-layer guide rail induction coil.
[0005] The multi-bent induction coil is formed by bending a single pipe multiple times and is hollow inside.
[0006] The overall structure of the multi-bent induction coil is U-shaped, and the structures of the first-layer guide rail induction coil and the second-layer guide rail induction coil are each U-shaped.
[0007] One water inlet and outlet is provided at the bottom of each of the two fixing plates.
[0008] A linear guide rail is arranged between the first-layer guide rail induction coil and the second-layer guide rail induction coil.
[0009] An insulating plate is arranged between the fixing plates.
[0010] The fixing plates and the insulating plate are connected by bolts and nuts.
[0011] Through holes for bolts to pass through are provided on the fixing plates and the insulating plate.
[0012] Compared with the prior art, the utility model can ensure the simultaneous quenching of both sides of the linear guide rail, and will no longer cause the problem of uneven quenching caused by uneven stress distribution when the linear guide rail is quenched separately on one side.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] The following further describes the utility model with reference to the accompanying drawings.
[0021] As Figure 5 shown, the inductor base includes fixing plates 1 and connecting pipes 2. There are two fixing plates 1, which are arranged opposite to each other. Connecting pipes 2 are respectively arranged on the outer sides of the fixing plates 1. The connecting pipes 2 are made of copper pipes, so the connecting pipes 2 have the characteristics of being not easily corroded, high-temperature resistant, high-pressure resistant, and low cost and are convenient for replacement. One end of each of the two connecting pipes 2 is connected to a multi-bent induction coil 7. As Figure 1 shown, the multi-bent induction coil 7 is formed by bending a single pipe multiple times. As Figure 3 shown, after being bent, the multi-bent induction coil 7 successively forms a first-layer guide rail induction coil 8 and a second-layer guide rail induction coil 9. As Figure 2 shown, two first magnetic conductors 6.1 are connected to the upper surface of the second-layer guide rail induction coil 9, and two second magnetic conductors 6.2 are connected to the lower surface of the first-layer guide rail induction coil 8. As Figure 6 , a linear guide rail 5 is arranged between the first-layer guide rail induction coil 8 and the second-layer guide rail induction coil 9.
[0022] The overall structure of the multi-bent induction coil 7 is U-shaped. Among them, the structure of the first-layer guide rail induction coil 8 and the second-layer guide rail induction coil 9 is also U-shaped. The U-shaped design of the first-layer guide rail induction coil 8 and the second-layer guide rail induction coil 9, combined with the magnetic conductor 6, can concentrate the magnetic field in the U-shaped structure of the multi-bent induction coil 7, playing the role of quenching both sides of the linear guide rail simultaneously. At the same time, the first magnetic conductor 6.1 and the second magnetic conductor 6.2 can use silicon steel sheets, which can shield other magnetic fields.
[0023] One water inlet and outlet 12 is provided at the bottom of each of the two fixing plates. Water flow is introduced into the water inlet and outlet holes 12 on one side, and the water flow flows out from the water inlet and outlet holes 12 on the other side. The water flow is used for cooling the entire inductor, preventing the multi-bent induction coil 7 from being burned out due to too high output power.
[0024] An insulating plate 10 is provided between the fixing plates 1. The insulating plate 10 is made of polytetrafluoroethylene plate. The polytetrafluoroethylene plate has high stability and is an ideal insulating material for the C pole.
[0025] The fixing plate 1 and the insulating plate 10 are connected by bolts 3 and nuts 4. The bolts 3 are nylon bolts, and the nuts 4 are brass nuts. The nylon bolts have good insulation performance, while the brass nuts have good heat conduction effect.
[0026] Through holes 11 for the bolts 3 to pass through are provided on the fixing plate 1 and the insulating plate 10.
[0027] The implementation principle of the present utility model is as follows. Technicians connect the two fixing plates 1 and the insulating plate 10 by bolts 3 and nuts 4, install connecting pipes 2 on both sides of the two fixing plates 1, put the two ends of the bent multi-bent induction coil 7 into the connecting pipes 2. U-shaped notches are respectively formed between the two first magnetic conductors 6.1 and the two second magnetic conductors 6.2 in the middle section of the multi-bent induction coil 7. At the same time, U-shaped notches are also formed between the two first magnetic conductors 6.1 and the corresponding second magnetic conductors 6.2 below. The magnetic conductor has a very high magnetic permeability and a very small magnetic resistance, and respectively generates a notch effect to concentrate the magnetic field into the U-shaped notches, improving the heating efficiency of the quenching device. The two fixing plates 1 are respectively connected to the positive and negative poles of the power supply. After being powered on, quenching starts. At this time, current is introduced into the first-layer guide rail induction coil 8 and the second-layer guide rail induction coil 9. The currents in the adjacent pipes of the first-layer guide rail induction coil 8 and the second-layer guide rail induction coil 9 are all reverse and equal, triggering the proximity effect, further concentrating the magnetic field between the first-layer guide rail induction coil 8 and the second-layer guide rail induction coil 9. High-pressure water is introduced through the water inlet and outlet holes 12 on one side of the inductor base, flows through the connecting pipes 2 and the multi-bent induction coil 7, and flows back to the water tank from the other water inlet and outlet holes 12 of the inductor base, playing the role of cooling the multi-bent induction coil 7. The linear guide rail 5 is slowly passed through the middle of the first-layer guide rail induction coil 8 and the second-layer guide rail induction coil 9. The linear guide rail 5 is always heated evenly on both sides during the up and down quenching, as Figure 6As shown, the linear guide rail 5 passes through the inductor between the first-layer guide rail induction coil 8 and the second-layer guide rail induction coil 9. Quenching on both sides of the linear guide rail 5 simultaneously can ensure uniform stress.
