Description

Technical Field

[0001] This utility model relates to the field of quenching equipment technology, specifically a gear quenching device. Background Technology

[0002] Gear quenching equipment is widely used in the performance enhancement process of various gears. Quenching treatment can significantly improve the surface hardness, wear resistance, and fatigue resistance of gears, ensuring that gears can withstand long-term loads and friction in mechanical transmission systems. It is a key step in ensuring gear service life and equipment operational reliability.

[0003] In traditional gear quenching processes, the heating stage often suffers from uneven heating due to improper heating element layout or inadequate control methods. This leads to inconsistent overall temperature, affecting the uniformity of subsequent quenching phase transformations. Furthermore, inadequate sealing design of the equipment during gear entry and exit from the heating chamber can cause significant heat loss, reducing heating efficiency and potentially exacerbating heating instability due to temperature fluctuations within the chamber. During the cooling and quenching stage, the lack of systematic nozzle arrangement in traditional spray systems results in varying cooling rates across different areas of the gear, potentially leading to insufficient localized hardness, stress concentration, and even cracking, failing to meet the quenching requirements for high-quality gears. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a gear quenching device to solve the problems mentioned in the background art, such as uneven heating of different parts of the gear, difficulty in ensuring the consistency of the overall temperature, affecting the uniformity of subsequent quenching phase transformation, and the instability of heating effect due to temperature fluctuations in the chamber, which easily leads to problems such as insufficient local hardness, stress concentration, or even cracking.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gear quenching device, comprising:

[0006] A frame, on the upper surface of which a heating box is mounted, heating resistance wires are evenly distributed inside the heating box, and a sealing frame is installed at the inlet of the heating box;

[0007] A motor is mounted on the upper surface of the frame. A lead screw is installed at the output end of the motor. A worktable is screwed onto the surface of the lead screw. A mounting frame is installed on the upper surface of the worktable. A sealing plate is installed on the surface of the mounting frame.

[0008] A water tank is located at the bottom of the frame. A water pump is installed at the outlet of the water tank. A water delivery pipe is installed at the outlet of the water pump. A water spray plate is installed at the outlet of the water delivery pipe. Quenching nozzles are evenly distributed on the surface of the water spray plate.

[0009] Preferably, a bracket is installed on the upper surface of the frame, and the water spray plate is installed at the bottom of the bracket. The support of the bracket allows the water spray plate to be stably positioned in a suitable location, so that water can be sprayed continuously and stably during the gear quenching process, ensuring uniform quenching effect.

[0010] Preferably, the upper surface of the frame is uniformly provided with water channels, and all quenching nozzles are designed at an angle. The water channels can quickly guide the wastewater generated during the quenching process away, preventing water accumulation from affecting the normal operation of the device and the working environment. The angled design of the quenching nozzles allows the sprayed water to impact the gears at a specific angle, increasing the contact area and impact force between the water and the gears, further improving quenching efficiency and quality.

[0011] Preferably, the upper surface of the workbench is uniformly provided with a first water permeable groove, and the upper surface of the mounting frame is provided with a second water permeable groove. The second water permeable groove is arranged in a fan shape. The first water permeable groove allows water dripping onto the workbench during quenching to flow smoothly down and avoid accumulation on the workbench. The fan-shaped arrangement of the second water permeable groove can better adapt to the shape of the gear, allowing water to flow through the gear from different directions and carry away heat. At the same time, it can also allow water to flow more smoothly through the mounting frame, preventing water accumulation from damaging the gear and the mounting frame.

[0012] Preferably, a limiting rod is installed on the upper surface of the frame. The limiting rod passes through the surface of the worktable and can limit the worktable to ensure that the worktable can stably drive the gear to move, thereby achieving a stable quenching operation.

[0013] Preferably, a recycling bin is installed inside the frame, and the water trough is connected to the inner cavity of the recycling bin. The recycling bin can collect the quenching wastewater flowing down from the water trough, which facilitates subsequent treatment and recycling of the wastewater.

[0014] Compared with the prior art, the present invention provides a gear quenching device, which has the following beneficial effects:

[0015] This gear quenching device uses a heating resistance wire to uniformly heat the incoming gear, helping to ensure consistent heating results. The starting motor moves the worktable via a lead screw, guiding the gear into the heating chamber. The sealing frame and sealing plate work together to reduce heat loss from the chamber, improving heating efficiency. After heating, the gear is moved to the quenching nozzles. A water tank supplies water to the spray plate via a pump and pipes. The evenly distributed quenching nozzles on the spray plate surface uniformly spray the heated gear, ensuring consistent cooling rates across all parts. The coordinated operation of these processes contributes to improving the quality of gear quenching. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides a technical solution, a gear quenching device. Please refer to [link / reference]. Figure 1 It includes a frame 1, and a heating box 2 is mounted on the upper surface of the frame 1. Please refer to [link / reference]. Figure 4 Heating resistance wires 3 are evenly distributed inside the heating box 2, and a sealing frame 4 is installed at the inlet of the heating box 2.

[0023] Please see Figure 2 Motor 5 is mounted on the upper surface of frame 1. A lead screw 6 is installed at the output end of motor 5. (See also...) Figure 3 A worktable 7 is screwed onto the surface of the lead screw 6. A mounting bracket 8 is mounted on the upper surface of the worktable 7. A sealing plate 9 is mounted on the surface of the mounting bracket 8.

[0024] Please see Figure 1 A water tank 10 is located at the bottom of the frame 1. A water pump 11 is installed at the outlet of the water tank 10, a water supply pipe 12 is installed at the outlet of the water pump 11, and a spray plate 13 is installed at the outlet of the water supply pipe 12. Please refer to [link / reference]. Figure 2 The surface of the water spray plate 13 is evenly distributed with quenching nozzles 14.

[0025] The heating resistance wires 3 evenly distributed inside the heating chamber 2 can uniformly heat the incoming gears, helping to ensure the consistency of the gear heating effect. The sealing frame 4 at the inlet of the heating chamber 2 cooperates with the sealing plate 9 on the surface of the mounting bracket 8. When the motor 5 drives the worktable 7 to move through the lead screw 6 to bring the gear into the heating chamber 2, it can reduce the heat loss inside the heating chamber 2 and improve the heating efficiency. The structure of the motor 5 driving the lead screw 6 to move the worktable 7 can realize the stable transport of the gear and ensure the stable position of the gear during the heating process, which is conducive to the smooth progress of the heating process. The water tank 10 supplies water to the spray plate 13 through the water pump 11 and the water supply pipe 12. The quenching nozzles 14 evenly distributed on the surface of the spray plate 13 can uniformly spray the heated gear, ensuring that the cooling rate of each part of the gear is consistent, which helps to improve the quenching quality of the gear.

[0026] A bracket 15 is installed on the upper surface of the frame 1, and a water spray plate 13 is installed at the bottom of the bracket 15. The support of the bracket 15 allows the water spray plate 13 to be stably positioned in a suitable position, so that water can be sprayed continuously and stably during the gear quenching process, ensuring uniform quenching effect.

[0027] The upper surface of the frame 1 is uniformly provided with water channels 16, and the quenching nozzles 14 are all designed at an angle. The water channels 16 can quickly guide the wastewater generated during the quenching process away, preventing water accumulation from affecting the normal operation of the device and the working environment. The angled design of the quenching nozzles 14 allows the sprayed water to impact the gears at a specific angle, increasing the contact area and impact force between the water and the gears, further improving quenching efficiency and quality.

[0028] Please see Figure 3 The upper surface of the workbench 7 is evenly provided with a first water permeable groove 17, and the upper surface of the mounting frame 8 is provided with a second water permeable groove 18. The second water permeable groove 18 is arranged in a fan shape. The first water permeable groove 17 allows water dripping onto the workbench 7 during quenching to flow smoothly down and avoid accumulation on the workbench 7. The fan-shaped arrangement of the second water permeable groove 18 can better adapt to the shape of the gear, allowing water to flow through the gear from different directions and carry away heat. At the same time, it can also allow water to flow more smoothly through the mounting frame 8, preventing water accumulation from damaging the gear and the mounting frame 8.

[0029] A limit rod 19 is installed on the upper surface of the frame 1. The limit rod 19 passes through the surface of the worktable 7 and can limit the worktable 7 to ensure that the worktable 7 can stably drive the gear to move and achieve stable quenching operation.

[0030] Please see Figure 1 The frame 1 is equipped with a recycling box 20. The water trough 16 is connected to the inner cavity of the recycling box 20. The recycling box 20 can collect the quenching wastewater flowing down from the water trough 16, which is convenient for subsequent treatment and recycling of the wastewater.

[0031] During operation: The starting motor 5 drives the lead screw 6 to rotate, which in turn drives the worktable 7 screwed onto the lead screw 6 to move stably along the limit rod 19. This allows the gear mounted on the mounting frame 8 on the worktable 7 to enter the heating box 2 through the sealing frame 4 at the inlet of the heating box 2. At this time, the sealing frame 4 cooperates with the sealing plate 9 on the surface of the mounting frame 8 to reduce heat leakage. The heating resistance wires 3 evenly distributed inside the heating box 2 heat the gear evenly. After heating is completed, the worktable 7 continues to move to the bottom of the water spray plate 13. The water in the water tank 10 is transported to the water spray plate 13 by the water pump 11 and the water supply pipe 12. The quenching nozzles 14 evenly and obliquely distributed on its surface spray the gear evenly. The water flows through the first permeable groove 17 evenly opened on the worktable 7 and the second permeable groove 18 arranged in a fan shape on the mounting frame 8. At the same time, the water flow grooves 16 evenly opened on the upper surface of the frame 1 quickly guide the quenching wastewater to the recycling box 20 installed inside the frame 1, completing the gear quenching process.
