Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of heat treatment auxiliary tools, specifically relating to a quenching material frame. Background Technology
[0002] The hot extrusion method for producing bearing sleeves allows for the one-step extrusion forming of inner and outer ring blanks, reducing material waste in subsequent separation processes and lowering production costs. Following the hot extrusion process, oil quenching is required, followed by air cooling to room temperature to form a uniform microstructure. Tempering is then performed to eliminate residual stress and stabilize dimensions.
[0003] During quenching, the bearing sleeve needs to be placed in a quenching frame, and the frame itself is immersed in the coolant to lower the bearing sleeve's temperature. However, current technology lacks a dedicated frame for bearing sleeves. During quenching, the bearing sleeves are randomly stacked in the frame, which can easily lead to rolling, collisions, and other issues, resulting in poor stability and hindering the quenching process.
[0004] Therefore, there is an urgent need for a special material frame for quenching bearing sleeves to ensure the stability of the bearing sleeves during the quenching process. Summary of the Invention
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a quenching material frame to solve the technical problem that the current quenching material frame cannot guarantee the stability of bearing sleeves and is not conducive to the smooth quenching process.
[0006] To achieve the above objectives, the technical solution of this utility model is as follows: a quenching material frame, comprising a support frame, multiple support components spaced apart on the support frame, a limiting component adjustablely disposed on the support frame, and a stopping component cooperating with the limiting component to stop the bearing sleeves. Each support component includes two parallel support rods, the distance between the two support rods being less than the diameter of the bearing sleeve. The limiting component includes an adjusting plate disposed between the two support rods and a limiting rod detachably connected to the adjusting plate. The limiting rod is parallel to the support rods, and the end of the limiting rod away from the adjusting plate is open. Multiple bearing sleeves are sleeved on the limiting rod and supported between the two support rods, arranged in an orderly manner. The adjusting plate and the stopping component are located on both sides of the bearing sleeves, thereby stopping the bearing sleeves sleeved on the limiting rod and improving the stability of the bearing sleeves.
[0007] Preferably, the support rod is a cylindrical rod.
[0008] Preferably, the adjusting plate is provided with a first connecting hole, and the end of the limiting rod is provided with a first screw for passing through the first connecting hole, and a nut is connected to the first screw to realize the detachable connection between the limiting rod and the adjusting plate.
[0009] Preferably, the first connecting hole is an elongated hole extending vertically.
[0010] Preferably, the stop assembly includes a stop plate and a connector for detachable connection with the support frame; when the stop assembly is connected to the support frame, the stop plate is perpendicular to the support rod and stops the bearing sleeve on the side away from the adjusting plate.
[0011] Preferably, the stop plate is provided with clearance grooves at positions corresponding to the support rod and the limiting rod.
[0012] Preferably, the connector is a second screw, and two second screws are provided, which are respectively vertically connected to the two ends of the stop plate; the second screws pass through the second connecting holes provided on the support frame opposite to the two support arms, and nuts are connected to the second screws to realize the detachable connection between the stop assembly and the support frame.
[0013] Preferably, the second connecting hole is an oblong hole.
[0014] The beneficial effects of adopting the technical solution of this utility model are as follows: This invention uses a support component and a limiting component to limit the bearing sleeve, and a stop component to stop the bearing sleeve, thereby restricting the storage position of the bearing sleeve and reducing excessive shaking or rolling, thus improving quenching stability. The support component includes two parallel, spaced-apart support rods. The limiting component includes an adjusting plate positioned on the support frame between the two support rods and a limiting rod detachably connected to the adjusting plate. The limiting rod is parallel to the two support rods and its end away from the adjusting plate is open. Based on this, the quenched bearing sleeve passes through the limiting rod and is supported between the two support rods, thus limiting the bearing sleeve. Multiple bearing sleeves can be simultaneously fitted onto a single limiting rod at the same horizontal level, ensuring they are in equivalent positions when entering the quenching liquid, guaranteeing consistent quenching of the bearing sleeves. The stop component, positioned on the side of the bearing sleeve away from the adjusting plate, works in conjunction with the adjusting plate to stop the bearing sleeve from both sides, preventing it from slipping off the limiting rod and improving the stability of the bearing sleeve placement.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0020] It should be noted that this material frame is not only suitable for the heat treatment of bearing sleeves, but also for the heat treatment of other annular or cylindrical workpieces, in order to ensure the stability of the workpiece during the heat treatment process.
[0021] The specific implementation method is as follows: Example 1, such as Figure 1-4As shown, a quenching material frame includes a support frame 1, a support assembly, a limiting assembly 3, and a stopping assembly 4. The support frame 1 consists of two first support arms 11 arranged opposite each other on the left and right sides and two second support arms 12 arranged opposite each other on the front and rear sides. Lifting rings 112 are provided at the four corners of the support frame 1 for connecting lifting ropes. In this embodiment, the lifting rings are located at the ends of the first support arms 11.
[0022] Multiple support components are provided, spaced apart on the support frame 1. Each support component includes two support rods 2. The two support rods 2 are spaced apart and parallel, and the distance between the two support rods 2 is less than the diameter of the bearing sleeve to be supported. The two ends of the support rods 2 can be connected to two second support arms 12 by welding.
[0023] The number of limiting components 3 is the same as that of the supporting components. Each limiting component 3 includes an adjusting plate 31 and a limiting rod 32. The adjusting plate 31 is vertically connected to the second supporting arm 12 and positioned between the two supporting rods 2 of the supporting component. One end of the limiting rod 32 is detachably connected to the adjusting plate 31, while the other end is open. The limiting rod 32 is parallel to the supporting rod 2 and its height is not lower than that of the supporting rod 2. A stopping component 4 is detachably connected to the supporting frame 1 and is used to cooperate with the limiting rod 32 to stop the bearing sleeve. Based on this, multiple hardened bearing sleeves can be arranged in an orderly manner on the limiting rod 32. The bearing sleeves are supported by the two supporting rods 2 of the supporting component, and the adjusting plate 31 and the stopping component 4 on both sides of the bearing sleeve on the same limiting rod 32 respectively stop the movement space of the bearing sleeves.
[0024] In this embodiment, the adjusting plate 31 and the second support arm 12 can be detachably connected. After the extruded bearing sleeve is placed on the limiting rod 32, the adjusting plate 31 is then connected to the support frame 1 to achieve continuity of the extrusion molding and quenching steps.
[0025] In this embodiment, a quenching material frame is used where a lifting rope is connected to the lifting ring 112, and the frame is lifted and transported via a drive component to facilitate quenching. The bearing sleeves to be quenched are arranged in an orderly manner on each limiting rod 32. A stop assembly 4 is connected to the support frame 1, and the bearing sleeves on one limiting rod 32 are stopped from both sides by the adjusting plate 31 and the stop assembly 4. Furthermore, the bearing sleeves are fitted onto the limiting rods 32 and supported by two support rods 2, thereby restricting the movement space of the bearing sleeves and reducing excessive shaking or rolling, thus improving the stability of the quenching process. When using this material frame to quench the bearing sleeves, the bearing sleeves are fitted onto the horizontal limiting rods 32, ensuring that each bearing sleeve is in an equivalent position, effectively guaranteeing the consistency of the quenching effect.
[0026] Furthermore, the support rod 2 is a cylindrical rod, and the contact between it and the bearing sleeve is an arc-shaped surface, thereby reducing the impact on the surface of the bearing sleeve.
[0027] Furthermore, a first connecting hole 311 is provided horizontally through the adjusting plate 31, and a first screw 321 is provided at the end of the limiting rod 32. The first screw 321 passes through the first connecting hole 311, and a first nut 322 is connected to the first screw 321, so that the limiting rod 32 and the adjusting plate 31 can be detachably connected by threaded engagement, which is simple to operate.
[0028] In this embodiment, the first connecting hole 311 is a vertically extending elongated hole to adjust the height of the limiting rod 32, that is, to adjust the distance between the limiting rod 32 and the support rod 2, thereby adapting to the limiting of bearing sleeves of different sizes and thicknesses and expanding the scope of application.
[0029] Furthermore, the stop assembly 4 includes a stop plate 41 and connecting members. The length of the stop plate 41 is close to the distance between the two first support arms 11, and the connecting members are located at both ends of the stop plate 41 and are used for detachable connection with the two first support arms 11. When the stop assembly 4 is connected to the support frame 1, the stop plate 41 is close to the limiting rod 32 and is located on the side of the bearing sleeve away from the adjusting plate 31, thereby stopping the bearing oil sleeved on the limiting rod 32.
[0030] Furthermore, clearance grooves 411 are provided on the stop plate 41 at positions corresponding to the support rod 2 and the limiting rod 32. The support rod 2 and the limiting rod 32 are embedded in the clearance grooves 411 to ensure the reliable stop of the bearing sleeve by the stop plate 41.
[0031] In this embodiment, the depth of the clearance groove 411 corresponding to the limiting rod 32 is greater than that of the clearance groove corresponding to the support rod 2, in order to accommodate the adjustability of the height of the limiting rod 32.
[0032] Furthermore, the connector uses a second screw 42, with two second screws 42 respectively vertically connected to both ends of the stop plate 41. A second connecting hole 111 is provided on the first support arm 11, through which the second screw 42 passes and is connected to the second nut 421, achieving a detachable connection with the second support arm 11.
[0033] Furthermore, the second connecting hole 111 is an elongated hole extending along the length of the first support arm 11, so as to facilitate the adjustment of the position of the stop plate 41 along the length of the limiting rod 32 and improve the flexibility of stopping the bearing sleeve.
[0034] Example 2, a quenching material frame, differs from Example 1 in that the support rod and the support frame are adjustable. The support rod can be driven to rotate by a driving device, thereby driving the bearing sleeve to rotate, ensuring the uniformity of quenching. Other structures will not be described in detail here.
[0035] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the technical solution of the present invention, or the direct application of the concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
