A square receiving cavity is opened at the top of the fixed baffle, and two symmetrically distributed vertical guide columns are fixedly installed inside the square receiving cavity.

[0004] This utility model cannot be folded during use, making it inconvenient to store and stack. Utility Model Content

[0005] The purpose of this invention is to provide a multifunctional vacuum heat treatment material frame to solve the problems mentioned in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional vacuum heat treatment material frame, comprising a material frame; the material frame is composed of a base plate, longitudinal side plates, and transverse side plates, a limit strip is installed on the outer side of the bottom end of the base plate, movable wheels are installed around the bottom end of the base plate, a rotating mechanism is installed on the bottom end of the longitudinal side plates and the transverse side plates, the bottom end of the rotating mechanism is installed on the outer side of the upper end of the base plate, and the upper connection of the longitudinal side plates and the transverse side plates is detachably installed and fixed by a fixing mechanism.

[0007] Preferably, limiting plates are provided on both sides of the transverse side plate, and the limiting plates are welded to both sides of the transverse side plate.

[0008] Preferably, the longitudinal side plate and the transverse side plate are provided with a corrosion-resistant layer on their outer sides, and the corrosion-resistant layer is a chromium-plated layer.

[0009] Preferably, the fixing mechanism consists of a fixing bolt and a fixing hole, the fixing hole being located at corresponding positions on both sides of the transverse side plate and the longitudinal side plate, and the fixing bolt being rotatably installed inside the fixing hole.

[0010] Preferably, the rotating mechanism consists of a shaft and a bearing seat. The bearing seat is installed around the upper part of the base plate, and the shaft is installed on both sides of the bottom of the transverse side plate and the longitudinal side plate. The shaft is rotatably installed on the upper side of the bearing seat.

[0011] Preferably, a handle is provided at the middle position of the longitudinal side plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The longitudinal and transverse side plates can rotate around the rotating mechanism, which makes it easy to fold the material frame and store it. The upper connection of the longitudinal and transverse side plates can be detached and fixed by the fixing mechanism.

[0014] 2. When the longitudinal side plate and the transverse side plate are assembled and connected, the limiting plate can fit against the side of the longitudinal side plate to accurately position the installation position of the longitudinal side plate, preventing the longitudinal side plate from shifting during the connection process. This ensures the accuracy and stability of the connection between the longitudinal side plate and the transverse side plate. At the same time, when the material frame carries the workpiece, if the workpiece moves closer to the sides of the transverse side plate during placement, the limiting plate can effectively block the workpiece and prevent it from slipping out of the gap between the transverse side plate and the longitudinal side plate. This further enhances the constraint ability of the material frame on the workpiece and ensures the safety of the workpiece during transportation and heat treatment.

[0015] 3. When it is necessary to fix the longitudinal side plate and the transverse side plate, align the fixing bolt with the corresponding fixing hole on both sides, and rotate the fixing bolt to gradually screw it into the fixing hole. The friction and locking force generated by the thread engagement between the fixing bolt and the inner wall of the fixing hole will tightly connect the longitudinal side plate and the transverse side plate together, achieving rigid fixation between the two. When it is necessary to adjust the position of the side plate or disassemble the material frame, rotate the fixing bolt in the opposite direction to screw it out of the fixing hole, which will release the constraint on the longitudinal side plate and the transverse side plate. The operation is simple and convenient, and the assembly and disassembly of the material frame can be quickly realized, improving the flexibility of the material frame.

[0016] 4. The bearing seat provides stable support and a rotation center for the shaft. When it is necessary to adjust the angle of the transverse or longitudinal side plate, an external force is applied to the side plate, and the shaft at the bottom of the side plate will rotate around the bearing seat, thereby driving the side plate to rotate around the bearing seat, realizing the opening or folding of the side plate. The fit clearance between the shaft and the bearing seat is precisely designed to ensure that the shaft can rotate flexibly and maintain a certain stability during the rotation process, preventing the side plate from rotating on its own when no external force is applied. This ensures that the side plate can remain stable temporarily after being adjusted to the appropriate position, which is convenient for subsequent locking through the fixing mechanism.

[0023] 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.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 In this embodiment of the utility model, a multifunctional vacuum heat treatment material frame includes a material frame 1. The material frame 1 is composed of a base plate 11, a longitudinal side plate 6, and a transverse side plate 4. A limit strip 12 is installed on the outer side of the bottom end of the base plate 11. Movable wheels 13 are installed around the bottom end of the base plate 11. A rotating mechanism 8 is installed at the bottom end of the longitudinal side plate 6 and the transverse side plate 4. The bottom end of the rotating mechanism 8 is installed on the outer side of the upper end of the base plate 11. The upper connection of the longitudinal side plate 6 and the transverse side plate 4 is detachably installed and fixed by a fixing mechanism 2.

[0025] Limiting plates 15 are provided on both sides of the transverse side plate 4. The limiting plates 15 are welded to both sides of the transverse side plate 4. When the longitudinal side plate 6 is assembled and connected with the transverse side plate 4, the limiting plates 15 can fit against the side of the longitudinal side plate 6 to accurately position the installation position of the longitudinal side plate 6, preventing the longitudinal side plate 6 from shifting during the connection process. This ensures the accuracy and stability of the connection between the longitudinal side plate 6 and the transverse side plate 4. At the same time, when the material frame 1 carries the workpiece, if the workpiece moves closer to the sides of the transverse side plate 4 during placement, the limiting plates 15 can effectively block the workpiece and prevent it from slipping out of the gap between the transverse side plate 4 and the longitudinal side plate 6. This further enhances the constraint ability of the material frame 1 on the workpiece and ensures the safety of the workpiece during transportation and heat treatment.

[0026] A corrosion-resistant layer 7 is provided on the outer side of the longitudinal side plate 6 and the transverse side plate 4. The corrosion-resistant layer 7 is a chrome-plated layer. The chrome-plated layer has excellent chemical stability and corrosion resistance, which can effectively prevent the longitudinal side plate 6 and the transverse side plate 4 from direct contact with these corrosive substances, prevent the side plates from being corroded and damaged, and extend the service life of the material frame 1. In addition, the surface of the chrome-plated layer is smooth and not easy to be stained with stains and residues, which facilitates the subsequent cleaning and maintenance of the material frame 1, ensuring that the material frame 1 maintains good performance and appearance during long-term use.

[0027] The fixing mechanism 2 consists of a fixing bolt 3 and a fixing hole 14. The fixing holes 14 are located at corresponding positions on both sides of the transverse side plate 4 and the longitudinal side plate 6. The fixing bolt 3 is rotatably installed inside the fixing hole 14. When it is necessary to fix the longitudinal side plate 6 and the transverse side plate 4, the fixing bolt 3 is aligned with the corresponding fixing holes 14 on both sides. By rotating the fixing bolt 3, it is gradually screwed into the fixing hole 14. The friction and locking force generated by the thread engagement between the fixing bolt 3 and the inner wall of the fixing hole 14 are used to tightly connect the longitudinal side plate 6 and the transverse side plate 4 together, achieving rigid fixation between them. When it is necessary to adjust the position of the side plate or disassemble the material frame 1, the fixing bolt 3 is rotated in the opposite direction to unscrew it from the fixing hole 14, thereby releasing the constraint on the longitudinal side plate 6 and the transverse side plate 4. The operation is simple and convenient, and the assembly and disassembly of the material frame 1 can be quickly realized, improving the flexibility of the material frame 1.

[0028] The rotating mechanism 8 consists of a shaft 9 and a bearing 10. The bearing 10 is installed around the upper end of the base plate 11. The shaft 9 is installed on both sides of the bottom end of the transverse side plate 4 and the longitudinal side plate 6. The shaft 9 is rotatably installed on the upper side of the bearing 10. The bearing 10 provides stable support and a rotation center for the shaft 9. When it is necessary to adjust the angle of the transverse side plate 4 or the longitudinal side plate 6, an external force is applied to the side plate. The shaft 9 at the bottom end of the side plate will rotate around the bearing 10 as the fulcrum, thereby driving the side plate to rotate around the bearing 10, realizing the opening or folding of the side plate. The fit clearance between the shaft 9 and the bearing 10 is precisely designed to ensure that the shaft 9 can rotate flexibly and maintain a certain stability during the rotation process, preventing the side plate from rotating on its own when no external force is applied. This ensures that the side plate can remain stable temporarily after being adjusted to the appropriate position, which is convenient for subsequent locking by the fixing mechanism 2.

[0029] A handle 5 is provided in the middle of the longitudinal side plate 6. When it is necessary to move the material frame 1 or adjust the position of the longitudinal side plate 6, the operator can hold the handle 5 and apply pulling or pushing force to drive the longitudinal side plate 6 to move, thereby realizing the overall movement of the material frame 1 or the rotation adjustment of the side plate. The handle 5 allows the operator to control the material frame 1 more effortlessly and stably during operation, avoiding the shaking of the material frame 1 or injury to the operator's hands due to improper force application, thus improving the safety and convenience of operation.

[0030] The working principle and usage process of this utility model: The main structure of the material frame 1 consists of a base plate 11, longitudinal side plates 6, and transverse side plates 4. This combination design provides a stable spatial frame for placing workpieces to be heat-treated. The limiting strip 12 installed on the outer side of the bottom end of the base plate 11 plays a key role when the material frames 1 are stacked: when multiple material frames 1 are stacked up and down, the limiting strip 12 can accurately engage with the corresponding position of the lower material frame 1, effectively limiting the relative range of movement between the material frames 1 in the horizontal direction, preventing the material frames 1 from shifting or tipping over due to external force shaking during stacking, and ensuring the stability and safety of multi-layer stacking. The moving wheels 13 around the bottom end of the base plate 11 greatly improve the mobility of the material frame 1, and the operator can easily move the material frame 1 to a vacuum by pushing it. Located near the heat treatment equipment or in a designated storage area, the material frame 1 can be moved without laborious handling, meeting the needs of flexible transfer during production. The rotating mechanism 8 at the bottom of the longitudinal side plate 6 and the transverse side plate 4 is the core component for adjusting the shape of the material frame 1. Its bottom end is installed on the outer side of the upper end of the base plate 11, so that the longitudinal side plate 6 and the transverse side plate 4 can rotate around the rotating mechanism 8 as the axis. This allows for flexible adjustment of the opening angle or folding state of the side plates according to the size and shape of the workpiece to be processed, facilitating the loading and unloading of the workpiece. The upper connection of the longitudinal side plate 6 and the transverse side plate 4 is detachably installed and fixed by the fixing mechanism 2. When the side plate is adjusted to the appropriate position, the fixing mechanism 2 can lock it firmly, ensuring the structural stability of the material frame 1 during the heat treatment process and preventing the workpiece from shifting due to the loosening of the side plate.

[0031] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
