[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0039] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0040] like Figure 1 and Figure 2 As shown, it is a structural schematic diagram of an existing induction heating device 100 for medium frequency hardening of rail chain links. The first sensor 101, the second sensor 102 and the third sensor 103 are made at the bottom of the device with the rail chain link product to be processed as a reference, and the first sensor 101, the second sensor 102 and the third sensor 103 are arranged in an inverted U-shaped opening as a whole, so as to form a heat treatment chamber for accommodating the rail chain link between the three groups of sensors. Each rail chain link product to be processed enters the heat treatment chamber from the inlet at the front end of the device and is output from the outlet at the rear end of the device to realize continuous heat treatment.

[0041] The induction heating device 100 is a double-station quenching device, which can realize medium-frequency quenching of the left and right chain rail segments at the same time. The first inductor 101, the second inductor 102 and the third inductor 103 used for quenching are all composed of a group of copper tubes arranged linearly in sequence, and each inductor is mainly self-made, and is formed by assembling and welding multiple sections of copper tubes. In order to fully harden the top surface of the rail chain segment 600, the third inductor 103 on the top surface is set to two groups, each group is composed of copper tubes arranged linearly in sequence, and the two groups of copper tubes are arranged at intervals on the left and right.

[0042] In addition, as a conventional solution, a cooling water inlet interface 104 and a cooling water outlet interface 105 are provided on the induction heating device 100 to form a cooling system of the device. The cooling water inlet interface 104 and the cooling water outlet interface 105 are respectively connected to the two end pipe openings of the first inductor 101, the second inductor 102 and the third inductor 103.

[0043] like Figure 1 , Figure 2 and Figure 3As shown, when the induction heating device 100 is used to heat-treat the rail chain link 600, the following technical defects mainly exist: because the first sensor 101, the second sensor 102 and the third sensor 103 thereon are manufactured by imitating the product rail chain link 600 as a reference, the gap consistency between the sensors manufactured in this way and the workpiece rail chain link 600 is insufficient, which can easily cause differences in product quality, and after the sensor is deformed during use, there is no shaping mold, and the shaping is mainly carried out by visual inspection. The size consistency of the left and right sensors is difficult to ensure, and the consistency of the gap adjustment between the sensor and the product during the production process does not meet the requirements, resulting in differences in the quality of the left and right chain track links produced.

[0044] It is well known that the product quality of the rail chain link 600 after heat treatment by the induction heating device 100 is mainly guaranteed by the heating effect of each inductor. Therefore, the core solution of this simple production and maintenance mold is to design and copy the mold 200 based on the size of the rail chain link 600 and the standard inductor, and then use the prepared copying mold 200 to in turn ensure the size accuracy of each inductor on the equipment.

[0045] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in order to solve the above problems existing in the existing induction heating equipment 100, a simple production and maintenance mold for the intermediate frequency inductor of the chain track segment is provided, which can realize the precise size control and convenient shaping of the inductor production by designing the profiling mold 200. Specifically, the profiling mold 200 is designed by profiling the reference track segment 600, and its overall cross section is an inverted T-shaped structure, and its structural design features are as follows:

[0046] The two side ends of the profiling mold 200 are designed to be arranged flatly with the inner side walls and the bottom of the first sensor 101 and the second sensor 102, respectively, for positioning and correcting the installation positions of the first sensor 101 and the second sensor 102. The top of the profiling mold 200 is designed to be arranged flatly with the bottom of the third sensor 103, so as to accurately locate the positions of each sensor, and for positioning and correcting the installation position of the third sensor 103.

[0047] In some of the embodiments, Figure 5 , Figure 6 and Figure 7 As shown, the profiling mold 200 is composed of an integrally designed mold body 201 and a mold base 202, and the mold body 201 and the mold base 202 are integrally processed from stainless steel, aluminum alloy or hard plastic material.

[0048] Referring to the structural shape of the rail link 600, the mold body 201 is designed to have an isosceles trapezoidal cross section, and a groove 203 is axially opened at the top midline position for assembling the split key 300. The mold base 202 is arranged at the bottom of the mold body 201, and its two ends extend outward from the mold body 201 to form a support platform with an inclined top. The support platform is designed to support the sensors on both sides, and serves the purpose of limiting and assisting shaping.

[0049] According to the shape of the rail chain link 600 to be processed, a corresponding shape of the profiling mold 200 is manufactured. Specifically, the effective height A of the mold body 201 is designed to be the height difference between the lower plane of the third sensor 103 and the lower planes of the first sensor 101 and the second sensor 102. The design standard is the required hardening layer depth of the rail chain link plus the reserved heating gap of 4mm between the sensor and the workpiece.

[0050] The bottom width B of the mold body 201 is the maximum width of the rail chain link 600 + 10mm; and the width B of the lower openings of the first and second sensors 101 and 102 on the left and right sides is the bottom width B of the mold body 201. A heating gap of 5mm is reserved between the first and second sensors 101 and 102 and the rail chain link. The manufacturing dimensions of the first and second sensors 101 and 102 on the left and right sides are consistent.

[0051] In addition, the inclination angle C of the inclined surfaces on both sides of the mold body 201 relative to the vertical direction is equal to the actual inclination angle of the rail chain link 600; and the inclined surfaces on both sides of the mold body 201 are arranged vertically at 90° relative to the top surfaces of the support platforms at both ends of the mold base 202, so as to be used to level the sensors or C-shaped silicon steel sheets 400 on both sides, thereby playing the role of limiting support.

[0052] In some of the embodiments, Figure 5 , Figure 6 and Figure 7 As shown, in order to ensure the consistency of the parallel gap between the two groups of copper tubes of the third sensor 103, the simple manufacturing and maintenance mold further includes a split key 300. The split key 300 is in the shape of a long strip, and its lower end is detachably embedded in the groove 203 at the top of the profiling mold 200, and its upper end is embedded between the two groups of copper tubes of the third sensor 103.

[0053] Specifically, a groove 203 with a width of 8 mm and a depth of 4 mm is processed on the upper plane of the top of the profiling mold 200, and a split key 300 with a width of 8 mm is wedged in when making the sensor, so as to ensure the parallel gap between the two groups of copper tubes of the third sensor 103 on the upper plane.

[0054] like Figure 4 and Figure 8As shown, in order to ensure the consistency of the parallel gaps between the copper tubes on each sensor, the simple manufacturing and maintenance mold also includes a plurality of C-shaped silicon steel sheets 400. Each of the C-shaped silicon steel sheets 400 can be detachably sleeved between two adjacent copper tubes, and each of the C-shaped silicon steel sheets 400 and the inclined surface of the profiling mold 200 do not interfere with each other.

[0055] Specifically, Fig. 9 As shown, the C-shaped silicon steel sheet 400 is made of silicon steel and has an overall C-shaped structure. The width along the axial direction of the device is 0.2 mm, the thickness at both ends is 3 mm, and the thickness in the middle is 5 mm. Figure 4 and Figure 8 As shown, a plurality of C-shaped silicon steel sheets 400 are respectively sleeved on the left and right groups of copper tubes of the third sensor 103. Since the width of the split key 300 is 8 mm, the gap between the two copper tubes is also 8 mm. After the C-shaped silicon steel sheets 400 are respectively sleeved on the copper tubes on both sides, since the width of both sides of the C-shaped silicon steel sheets 400 is 3 mm, the gap between the left and right copper tubes is still 2 mm, thus avoiding sparks during use due to the small gap between the two adjacent copper tubes.

[0056] In the actual production process, the copper tubes on each sensor are placed flush with the contoured mold 200, and then the copper tubes are welded and fixed to ensure that the effective size of the sensor accurately meets the design requirements, and the plane and the gaps on both sides are uniform and consistent. The left and right sensors are made with the same mold and have the same size, ensuring product quality consistency.

[0057] At the same time, based on the cooperation of the profiling mold 200, after the welding and production of each sensor is completed, a C-shaped silicon steel sheet 400 with a fixed width of 0.2mm and a thickness of 3mm at both ends can be installed and pressed on the plane and the heating copper tubes on both sides as needed to improve the heating efficiency.

[0058] In addition, if Figure 8 As shown, the simple manufacturing and maintenance mold for the intermediate frequency sensor of the track section also includes a gasket 500 for shaping each sensor, the gasket 500 is arranged on the top of the profiling mold 200, and it is arranged flush with the lower plane of the third sensor 103; and the top surface of the support at both ends of the profiling mold 200 is abutted and connected with the C-shaped silicon steel sheet 400 on both sides.

[0059] During use, each sensor may be deformed due to its own weight, heat, etc., so each sensor needs to be regularly shaped. Specifically, the shaping is performed using the profiling mold 200. After the C-shaped silicon steel sheet 400 is installed, the split key 300 will interfere with the flatness of the plane of the third sensor 103 and the upper plane of the profiling mold 200. Therefore, the split key 300 is removed, and a gasket 500 corresponding to the thickness of the silicon steel sheet is inserted into the upper plane of the profiling mold 200 to ensure that the lower plane of the third sensor 103 is flat with the upper plane of the profiling mold 200. The C-shaped silicon steel sheets 400 on both sides and the inclined surfaces on both sides of the profiling mold 200 do not interfere with each other. Without disassembling the C-shaped silicon steel sheet 400, the shaping of the planar third sensor 103 and the first sensor 101 and the second sensor 102 on both sides can be effectively completed.

[0060] The manufacturing and maintenance mold is assembled by a profiling mold 200, a split key 300, a C-shaped silicon steel sheet 400 and a gasket 500, and a split structure design is adopted between each other, which can be assembled and used flexibly as needed. Based on the profiling mold 200, it can be ensured that the manufacturing size of each sensor meets the design requirements. When the copper tube is deformed and needs to be reshaped during the later use, because the C-shaped silicon steel sheet 400 cannot be disassembled, the split split key 300 and the gasket 500 are used to achieve the purpose of convenient maintenance.
