Description

Technical Field

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

[0002] In the field of ring forging processing, the main function of heat treatment equipment is to quench the ring forgings. By controlling the heating and cooling process, the hardness, strength and other mechanical properties of the ring forgings are improved to meet the needs of different industrial applications.

[0003] However, existing heat treatment equipment for ring forgings has significant problems in practical applications. During the quenching process, the ring forging is usually in a fixed state, lacking an effective rotation drive mechanism. This leads to differences in the contact area and time between different parts of the ring forging and the coolant, easily resulting in localized overheating or uneven cooling. For example, a fixed-position ring forging may experience uneven coolant flow distribution, causing some areas to cool too quickly, forming excessive internal stress, while other areas may not cool sufficiently to achieve the expected hardness requirements. Ultimately, this results in inconsistent overall performance of the ring forging and poor product quality stability. Utility Model Content

[0004] In view of this, the present invention provides a ring forging quenching device, which can support the ring forging through the base, and the rotating shaft drives the ring forging to rotate in the cooling chamber, so as to avoid local overheating or uneven cooling of the ring forging.

[0005] To solve the above-mentioned technical problems, this utility model provides a quenching device for ring forgings, including a quenching box with a cooling chamber inside. The bottom of the cooling chamber is connected to a base, and the outer surface of the ring forging abuts against the end face of the base. The base can support the ring forging, keeping it stable in the cooling chamber of the quenching box and providing reliable basic support for the subsequent quenching process.

[0006] A slot is cut into the base along its axis, and a driving component is installed within the slot. The outer surface of the driving component abuts against the outer surface of the ring forging. The function of the driving component is to rotate the ring forging. This rotation ensures more uniform heating or cooling during the quenching process, improving the quenching effect. The driving component includes a rotating shaft that can rotate within the slot. One end of the shaft is connected to a drive motor, which is located on one side of the quenching chamber. The drive motor provides power for the rotation of the shaft, enabling the driving component to rotate the ring forging. The outer surface of the shaft is covered with a wear-resistant layer to increase friction with the ring forging, allowing the shaft to better drive the ring forging to rotate and preventing the ring forging from remaining stationary, which could cause uneven heating or cooling.

[0007] The base has an arc-shaped structure that matches the shape of the outer surface of the ring forging. This increases the contact area between the base and the ring forging, making the base support the ring forging more stable. It also helps the ring forging maintain good coaxiality during rotation.

[0008] The quenching chamber is equipped with limiting components at both ends. These components prevent the ring forging placed on the base from tilting, ensuring accurate positioning during quenching and avoiding any impact on quenching quality due to tilting. The limiting components include a first cylinder connected to the side wall of the quenching chamber. The output end of the first cylinder is connected to a base plate located within the cooling chamber. The base plate has rollers, the outer surfaces of which abut against the outer surface of the ring forging. The first cylinder drives the base plate to move, ensuring close contact between the rollers and the outer surface of the ring forging. The rolling support and limiting effect of the rollers prevents the ring forging from tilting or shifting horizontally. The base plate has a through hole containing a bidirectional cylinder. The output end of the bidirectional cylinder has a clamping wheel, the outer surface of which abuts against the side of the ring forging. The bidirectional cylinder can drive the clamping wheel to move towards the side of the ring forging. By clamping the side of the ring forging with the clamping wheel, the position of the ring forging is further fixed, preventing it from tilting in the vertical direction. It forms a cooperative limit with the roller, providing stable constraint on the ring forging from multiple directions, ensuring that the ring forging maintains the correct posture during the quenching process, and ensuring the smooth progress of the quenching process and the stability of the quenching quality.

[0009] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0010] 1. Improve quenching uniformity: The ring forging is rotated by the drive component (shaft), so that it is heated or cooled more evenly during the quenching process, avoiding local overheating or uneven cooling, and improving the quenching effect and product performance consistency.

[0011] 2. Enhanced support stability: The base adopts an arc-shaped structure, which is adapted to the shape of the outer surface of the ring forging, increasing the contact area and making the support more stable. At the same time, it helps the ring forging maintain good coaxiality when rotating, ensuring rotational stability and accuracy.

[0012] 3. Multi-directional limiting and anti-tilting: The limiting components (first cylinder, base plate, roller, bidirectional cylinder, clamping wheel) work together to constrain the ring forging in both horizontal and vertical directions.

[0013] 4. Optimize drive reliability: A wear-resistant layer is set on the outer surface of the shaft to increase the friction with the ring forging, ensuring that the shaft can effectively drive the ring forging to rotate, avoiding rotation failure due to insufficient friction, and further ensuring the uniformity of quenching.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-2 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0018] like Figure 1-2 As shown:

[0019] This embodiment provides a quenching device for ring forgings, including a quenching box 1 with a cooling chamber 2 inside. The bottom of the cooling chamber 2 is fixedly connected to a base 3 by bolts. The outer surface of the ring forging abuts against the end face of the base 3. The base 3 provides stable support for the ring forging through end face contact, keeping the ring forging in a fixed position within the cooling chamber 2 of the quenching box 1, thus laying the foundation for the subsequent quenching process.

[0020] The base 3 has a slot 4 along its axis, and a driving component is arranged within the slot 4. The outer surface of the driving component abuts against the outer surface of the ring forging. The driving component includes a rotating shaft 5, which can rotate around its own axis within the slot 4. One end of the rotating shaft 5 is connected to the output end of the drive motor 6 via a coupling. The output end of the drive motor 6 has a seal at the point where it passes through the side wall of the quenching chamber 1 to prevent the coolant in the quenching chamber 1 from flowing out. The drive motor 6 is bolted to one side of the quenching chamber 1 and provides rotational power to the rotating shaft 5 through a transmission mechanism, thereby enabling the driving component to drive the ring forging to rotate. To enhance the driving effect, a wear-resistant layer 7 is provided on the outer surface of the rotating shaft 5. By increasing the friction with the ring forging, it ensures that the rotating shaft 5 can effectively drive the ring forging to rotate, avoiding the situation where the ring forging cannot rotate due to insufficient friction, resulting in uneven heating or cooling.

[0021] The base 3 is designed with an arc-shaped structure, the curvature of which matches the shape of the outer surface of the ring forging. This fit increases the contact area between the base 3 and the ring forging, improving the stability of the base 3 in supporting the ring forging and helping the ring forging maintain good coaxiality during rotation, thus ensuring the stability and accuracy of rotation.

[0022] The quenching chamber 1 is equipped with limiting components at both ends to prevent the ring forging placed on the base 3 from tilting, ensuring the accurate positioning of the ring forging during the quenching process. The limiting components include a first cylinder 8 connected to the side wall of the quenching chamber 1. The output end of the first cylinder 8 is connected to a base plate 9, which is located inside the cooling chamber 2. A roller 10 is mounted on the base plate 9, with its outer surface contacting the outer surface of the ring forging. The first cylinder 8 drives the base plate 9 to move horizontally, ensuring close contact between the roller 10 and the outer surface of the ring forging. Through the rolling support and limiting effect of the roller 10, the ring forging is prevented from tilting or shifting horizontally. Simultaneously, the base plate 9 has a through hole 11, within which a bidirectional cylinder 12 is installed. The output end of the bidirectional cylinder 12 has a clamping wheel 13, the outer surface of which contacts the side of the ring forging. The bidirectional cylinder 12 drives the clamping wheel 13 to move towards the side of the ring forging. The clamping action of the clamping wheel 13 further fixes the ring forging in the vertical direction, preventing it from tilting. The roller 10 and the clamping wheel 13 form a coordinated limiting mechanism, providing stable constraint to the ring forging from multiple horizontal and vertical directions. This ensures that the ring forging maintains the correct posture throughout the quenching process, guaranteeing the smooth progress of the quenching process and the stability of the quenching quality.

[0023] Working principle: The ring forging is lifted by a hoisting device and placed in the cooling chamber 2 of the quenching box 1. The outer surface of the ring forging abuts against the end face of the base 3, which supports the ring forging. The base 3 has an arc-shaped structure, and its curvature matches the shape of the outer surface of the ring forging, increasing the contact area to improve the stability of the support and ensure the coaxiality of the ring forging during rotation. A driving component is installed in the slot 4 at the axis of the base 3. The driving component includes a rotating shaft 5, one end of which is connected to a drive motor 6. The drive motor 6 provides rotational power to the rotating shaft 5. The wear-resistant layer 7 on the outer surface of the rotating shaft 5 increases the friction with the ring forging, causing the ring forging to rotate in the cooling chamber 2, making it more uniformly heated or cooled during the quenching process. The limiting components at both ends of the quenching box 1 prevent the ring forging from tilting. The first cylinder 8 in the limiting component drives the base plate 9 to make the roller 10 abut against the outer surface of the ring forging, preventing horizontal tilting or displacement. The bidirectional cylinder 12 in the base plate 9 drives the clamping wheel 13 to abut against the side of the ring forging, preventing vertical tilting. The roller 10 and the clamping wheel 13 work together to limit the ring forging, providing stable constraint on the ring forging from multiple directions, ensuring that the ring forging maintains the correct posture during the quenching process, and ensuring the smooth progress of the quenching process and the stability of the quenching quality.
