Description

Technical Field

[0001] This utility model relates to a quenching device, specifically, to a detachable external tooth induction quenching device. Background Technology

[0002] The induction coil of the external gear ring direct injection induction hardening device is made of copper tubes of different types and shapes. Holes are drilled on the surface of the copper tubes to form a self-contained spray cooling method. The copper tubes cannot be disassembled and opened. After a certain period of induction hardening of the external gear ring, problems such as clogging of the spray holes and inability to clean them will occur. This makes it impossible to guarantee the spray pressure, flow rate and uniformity during quenching and cooling, which seriously affects the product quality. At present, there is no detachable external gear ring direct injection induction hardening device.

[0003] For example, Chinese patent CN219637280U discloses an induction hardening device for internal splines, which includes a support base, an inner spray assembly, and an outer spray assembly. Both the inner and outer spray assemblies are installed on the support base. The inner spray assembly includes an induction coil and a magnetic conductor. The induction coil is wound from a hollow copper tube and is sleeved with the outer spray assembly. A space is left between the outer spray assembly and the induction coil for placing the workpiece with internal splines. The magnetic conductor is connected to the induction coil and is used to heat the workpiece with internal splines. The outer spray assembly and the induction coil spray quenching agent onto the workpiece with internal splines in opposite directions for hardening the inner and outer walls of the workpiece with internal splines.

[0004] The induction coil in the internal spline induction hardening device is made of a hollow copper tube and is connected to the external spray assembly. The copper tube is a non-removable structure, and its interior is difficult to clean. Utility Model Content

[0005] The purpose of this invention is to provide a detachable external tooth induction hardening device.

[0006] To achieve the above objectives, this utility model provides a detachable external tooth induction hardening device, comprising an upper cover ring plate and a lower cover ring plate arranged opposite to each other. A copper plate coil and a water baffle plate are arranged between the upper cover ring plate and the lower cover ring plate. The copper plate coil is located inside the water baffle plate. Both the upper cover ring plate and the lower cover ring plate are provided with slots. Two parallel busbars are engaged in the slots. The two ends of the copper plate coil are respectively welded and fixed to one of the busbars. The two ends of the water baffle plate are respectively insulated and connected to one of the busbars. Multiple spray holes are arranged on the copper plate coil. The upper cover ring plate, the lower cover ring plate, the water baffle plate, the copper plate coil and the busbars at both ends enclose a water-holding cavity. Multiple quick connectors communicating with the water-holding cavity are provided on the upper cover ring plate. The upper cover ring plate and the lower cover ring plate are detachably locked together by a first bolt.

[0007] Preferably, an insulating fixing plate is fixedly connected to the side of the manifold located inside the water storage cavity; an insulating connecting plate perpendicular to the outer end of the insulating fixing plate is fixedly connected to the outer end of the insulating fixing plate, and the end of the water baffle plate is connected to the insulating connecting plate by a third screw.

Detailed Implementation

[0022] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0023] In this utility model, unless otherwise stated, directional terms such as "up, down, left, right, front, back, inside, outside" in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as a limitation on the term.

[0024] See Figure 1-2 The detachable external gear induction hardening device shown includes an upper cover ring plate 1 and a lower cover ring plate 2 arranged opposite each other. A copper plate coil 5 and a water baffle plate 6 are arranged between the upper cover ring plate 1 and the lower cover ring plate 2. The copper plate coil 5 is located inside the water baffle plate 6. Both the upper cover ring plate 1 and the lower cover ring plate 2 are provided with a slot 17. Two parallel busbars 14 are engaged in the slot 17. The two ends of the copper plate coil 5 are respectively welded and fixed to one of the busbars 14. Both ends of the water plate 6 are insulated and connected to a manifold 14. Multiple spray holes 19 are arranged on the copper plate coil 5. The upper cover ring plate 1, the lower cover ring plate 2, the water baffle 6, the copper plate coil 5 and the manifolds 14 at both ends enclose a water storage cavity. Multiple quick connectors 16 communicating with the water storage cavity are provided on the upper cover ring plate 1. The quick connectors 16 can be stainless steel connectors. The upper cover ring plate 1 and the lower cover ring plate 2 are detachably locked together by a first bolt.

[0025] Through the implementation of the above technical solution, firstly, quenching liquid can be filled into the water storage cavity by connecting the water pipe through the quick connector 16. The quenching liquid is sprayed onto the quenched parts through multiple spray holes 19 to achieve the purpose of quenching. Secondly, the induction coil does not use a copper tube winding method, but directly uses a copper plate coil 5. The two ends of the copper plate coil 5 are welded to the corresponding busbar 14. The current in the copper plate coil 5 is passed through the power supply through the busbar 14 to achieve the purpose of induction heating. Finally, the upper cover ring plate 1 and the lower cover ring plate 2 are loosened by the first bolt, so that the water baffle plate 6, the copper plate coil 5 and the busbar 14 at both ends can be easily separated, so that the inner wall of the water storage cavity is fully exposed for easy cleaning.

[0026] In this embodiment, an insulating fixing plate 7 is fixedly connected to the side of the manifold 14 located within the water storage cavity; an insulating connecting plate 9 perpendicular to the outer end of the insulating fixing plate 7 is fixedly connected to it, and the end of the baffle plate 6 is connected to the insulating connecting plate 9 by a third screw 8. Furthermore, the insulating fixing plate 7 and the insulating connecting plate 9 are integrally connected, forming an L-shaped structure. The two ends of the baffle plate 6 abut against the inner side of the adjacent insulating fixing plate 7, and the side of the baffle plate 6 is connected to the insulating connecting plate 9 by a third screw 8, thus fixing the end of the baffle plate 6 and facilitating disassembly.

[0027] In this embodiment, the inner surfaces of the upper cover ring plate 1 and the lower cover ring plate 2 are provided with grooves 3 for engaging the baffle plate 6, and a sealing strip 4 is embedded in the grooves 3. The sealing strip 4 enhances the sealing performance between the baffle plate 6 and the upper cover ring plate 1 and the lower cover ring plate 2, preventing liquid leakage. Furthermore, when the first bolt is tightened, the upper and lower edges of the baffle plate 6 are engaged in the corresponding grooves 3, making contact with the sealing strip 4. In addition, to further enhance the sealing performance, a sealing coating can be sprayed onto the inner surfaces of the insulating fixing plate 7 and the insulating connecting plate 9, ensuring a good seal at all contact points.

[0028] In this embodiment, an insulating plate 13 is provided between the two busbars 14. Through the implementation of the above technical solution, adjacent busbars 14 can be insulated from each other.

[0029] In this embodiment, the two manifolds 14 are fixed together by a plurality of second bolts. For example, when there are two second bolts, one is set outside the water storage cavity and passes through the two manifolds 14 and the middle insulating plate 13 in sequence, and the other is set inside the water storage cavity and passes through the two manifolds 14, the middle insulating plate 13 and the insulating fixing plate 7 in sequence.

[0030] In this embodiment, to further provide a second bolt, the second bolt includes a second screw 11 and an insulating washer 10 and a second nut 12 sequentially sleeved on the first screw 20. The insulating washer 10 can preferably be made of polytetrafluoroethylene to increase insulation performance.

[0031] In this embodiment, the inner surfaces of the upper cover ring plate 1 and the lower cover ring plate 2 are provided with L-shaped stepped grooves 21 for engaging the copper plate coil 5. This arrangement limits the upper and lower edges of the copper plate coil 5, allowing for faster alignment and assembly, and improving structural stability. Of course, to improve sealing performance, a second sealing gasket 18 can also be laid on the L-shaped stepped groove 21.

[0032] In this embodiment, to further provide a first bolt, the first bolt includes a first screw 20 and a first sealing gasket 18 and a first nut 15 sequentially sleeved on the first screw 20. Each first bolt is fitted with two first sealing gaskets 18, the first sealing gaskets 18 being T-shaped gaskets, which can partially extend into the mounting hole to achieve better sealing.

[0033] In this invention, the upper cover ring plate 1, the lower cover ring plate 2, the insulating fixing plate 7, and the insulating plate 13 can all be made of FR4 fiberglass board, and the insulating connecting plate 9 can be made of epoxy board to obtain good insulation performance. This ensures that the two ends and edges of the rear water baffle plate 6 are not directly electrically connected to the copper plate coil 5 and the busbar 14. In this way, the current can only be induced and heated through the busbar 14 and the copper plate coil 5, avoiding other ineffective current diversion paths and improving heating efficiency.

[0034] In this utility model, under the tightening of the first bolt, the upper and lower sides of the copper plate coil 5 are respectively pressed into the corresponding L-shaped stepped groove 21, and the upper and lower sides of the water baffle 6 are respectively pressed into the corresponding groove 3. They are sealed by the second sealing gasket 18 and the sealing strip 4 respectively. The sealing material of the second sealing gasket 18 and the sealing strip 4 can be silicone material, which avoids water leakage during spraying.

[0035] In addition, a sealing coating can be sprayed onto the contact points between the ends of the upper cover ring plate 1 and the lower cover ring plate 2 and the side of the manifold 14, so that the contact parts have good sealing performance.

[0036] The first screw 20, the second screw 11, the third screw 8, the first nut 15, and the second nut 12 in this invention are all made of stainless steel to prevent corrosion from long-term contact with water. The water baffle 6 can be made of copper plate, or other materials can be selected as needed.

[0037] The detachable external gear induction hardening device of this utility model can be cleaned periodically after induction hardening. It can be opened by simply removing the first bolt that locks the upper cover ring plate 1 and the lower cover ring plate 2 in the induction hardening device. After cleaning and maintenance, the upper cover ring plate 1 and the lower cover ring plate 2 can be installed using the first bolt and then used normally.

[0038] This utility model has a simple structure and is easy to disassemble. The induction hardening device can be disassembled, cleaned and maintained at any time, which solves the problems of water spray hole blockage and internal debris in the hardening device, improves the service life of the induction hardening device, stabilizes the hardening quality and reduces the production cost of enterprises.

[0039] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0040] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0041] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
