Description

Technical Field

[0001] This utility model belongs to the field of quenching tooling technology, and specifically relates to a vibration-resistant material tray tooling for quenching large circular forgings. Background Technology

[0002] During water quenching, the water on the workpiece surface boils and vaporizes. When the quenching medium on the workpiece surface vaporizes to form a vapor film, the rupture and renewal process of the vapor film is uneven. In some rough surface areas of the workpiece, the vapor film may rupture more easily, accelerating the cooling rate. In smooth surface areas, the vapor film may persist for a period of time. This difference in cooling rate leads to an imbalance of forces on the workpiece surface, causing workpiece vibration. For large forgings such as wide-edge rings or discs, the surface area is large, resulting in a larger and more numerous vapor film and vapor pocket, causing severe vibration. Using traditional trays with L-shaped hooks for quenching operations is problematic because the hooks are prone to detaching, causing the workpiece to tip over and damaging the quenching tank components. Furthermore, suspending the hot workpiece on the tray and then securing it with hooks is neither safe nor convenient. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a circular large forging quenching anti-vibration tray tooling. Through the cooperation of the limiting mechanism and the baffle, the workpiece can be fixed during quenching, preventing the workpiece from tipping over, enhancing the safety of quenching work and improving work efficiency.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A circular large forging quenching anti-vibration tray tooling includes a U-shaped frame, which is mounted on a disc. A limit mechanism is installed on the end of the U-shaped frame away from the disc, and a baffle is installed on the end of the U-shaped frame away from the limit mechanism.

[0006] The limiting mechanism includes a first support plate and a second support plate. The first support plate is located above the second support plate. A rotating shaft is installed between the first and second support plates. A limiting plate is installed between the first and second support plates and the rotating shaft. The first support plate has a first through hole, the second support plate has a second through hole, and the limiting plate has a third through hole. A positioning rod is slidably installed in the first through hole of the first support plate. The positioning rod can pass through the third through hole of the limiting plate and enter the second through hole of the second support plate, thereby preventing the limiting plate from rotating and limiting the limiting plate. A receiving groove is formed between the baffle on one side of the U-shaped frame and the first and second support plates on the other side.

[0007] Preferably, the U-shaped frame is mounted on the disc by bolts, and the number of bolts is two.

[0008] Preferably, the limiting plate is L-shaped.

[0009] Preferably, the first support plate, the second support plate, and the baffle are welded onto the U-shaped plate.

[0010] The beneficial effects of this utility model are:

[0011] 1) The combination of the limiting mechanism and the baffle can fix the workpiece during quenching, prevent the workpiece from tipping over, enhance the safety of the quenching process, and improve work efficiency.

[0012] 2) The U-shaped frame is bolted to the disc, with two bolts used to facilitate the overall installation of the U-shaped frame. It can also accommodate discs of different thicknesses, thus expanding its application range.

[0013] 3) The limiting plate is L-shaped, which facilitates the manufacturing and processing of the limiting plate.

[0014] 4) The first support plate, the second support plate, and the baffle are welded onto the U-shaped plate to facilitate overall assembly. Attached Figure Description

[0019] The following is in conjunction with the appendix Figure 1-3 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] A circular large forging quenching vibration-resistant tray fixture includes a U-shaped frame 1, which is mounted on a circular disc. A limiting mechanism is installed on the end of the U-shaped frame away from the disc, and a baffle 8 is installed on the end of the U-shaped frame 1 away from the limiting mechanism. The limiting mechanism includes a first support plate 3 and a second support plate 4, with the first support plate 3 located above the second support plate 4. A rotating shaft 5 is installed between the first support plate 3 and the second support plate 4, and a limiting plate 7 is installed between the first support plate 3 and the second support plate 4 and on the rotating shaft 5. The support plate 3 has a first through hole 31, the second support plate 4 has a second through hole 41, and the limiting plate 7 has a third through hole 71. A positioning rod 6 is slidably installed in the first through hole 31 on the first support plate 3. The positioning rod 6 can pass through the third through hole 71 on the limiting plate 7 and enter the second through hole 41 on the second support plate 4, so that the limiting plate 7 cannot rotate and is limited. The baffle 8 on one side of the U-shaped frame 1 forms a receiving groove with the first support plate 3 and the second support plate 4 on the other side.

[0022] The U-shaped frame 1 is mounted on the disc by two bolts 2, which facilitates the overall installation of the U-shaped frame 1 and can also accommodate discs of different thicknesses, thus expanding its application range. The limiting plate 7 is L-shaped, which facilitates the manufacturing and processing of the limiting plate 7. The first support plate 3, the second support plate 4, and the baffle 8 are welded to the U-shaped plate, which facilitates the overall assembly.

[0023] A circular large forging quenching anti-vibration tray tooling has the following working process: When in use, the positioning rod 6 is raised and the limiting plate 7 is rotated so that the positioning rod 6 abuts against the limiting plate 7. The hot workpiece is hoisted onto the tray and the L-shaped hook is pushed into the receiving groove while colliding with the limiting plate 7 to make it rotate. The positioning rod can pass through the third through hole 71 on the limiting plate 7 and enter the second through hole 41 on the second support plate 4. The baffle 8 and the limiting plate 7 then restrict the rotation and displacement of the L-shaped hook, thereby preventing it from falling off due to vibration.

[0024] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
