Description

Technical Field

[0001] This utility model belongs to the field of powder metallurgy technology, and in particular relates to a powder metallurgy mixing device that is easy to maintain. Background Technology

[0002] A powder metallurgy mixing device is a specialized device for uniformly mixing different metal powders, non-metal powders, alloy powders, and various additives. It is a key upstream process device in the powder metallurgy production process. Its core task is to efficiently, pollution-free, and uniformly mix various powder raw materials and additives together, and overcome segregation problems to provide qualified mixed powder materials for subsequent pressing and sintering processes.

[0003] Based on the above, the inventors have discovered the following shortcomings in existing powder metallurgy mixing devices: 1. The mixing tank and support frame are integrated, which makes the disassembly and maintenance of the mixing tank more difficult. It is not convenient to make the mixing tank and support frame separate to allow for quick disassembly and maintenance of the mixing tank. 2. The electric-driven mixing tank has a large capacity, which is not suitable for mixing small amounts of metallurgical powders. It is also inconvenient to add manual mixing measures to the device to reduce the capacity of the mixing tank to make it suitable for small-scale mixing. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a powder metallurgy mixing device that is easy to maintain. This addresses the issues of existing mixing tanks and support frames being integrated, which makes disassembly and maintenance of the mixing tank difficult and inconvenient. It also avoids the problem of using separate mixing tanks and support frames for quick disassembly and maintenance. Furthermore, electrically driven mixing tanks have large capacities, making them unsuitable for mixing small quantities of metallurgical powders, and it is inconvenient to add manual mixing features to the device to reduce the problem of the mixing tank's capacity being suitable for small-scale mixing.

[0005] The purpose and effectiveness of this convenient-to-maintain powder metallurgy mixing device are achieved through the following specific technical means: A powder metallurgy mixing device that is easy to maintain includes a device body; the device body is provided with a powder mixing barrel, the outer circumference of the top of the powder mixing barrel is provided with a threaded annular groove, the left side of the outer circumference of the powder mixing barrel is provided with a U-shaped handle, the bottom wall of the powder mixing barrel is provided with a through bearing hole, a mixing sealing cover is installed on the annular groove of the powder mixing barrel by threads, the inner circumference of the mixing sealing cover is provided with threads, the outer circumference of the mixing sealing cover is provided with an anti-slip groove in an annular array, a mixing rotating fan is installed at the top inside the bearing hole of the powder mixing barrel by bearing, a bearing column is provided at the center of the mixing rotating fan, a mixing plate is provided in an annular array on the outer circumference of the bearing column of the mixing rotating fan, a fixing column is provided at the bottom end face of the bearing column of the mixing rotating fan, and a regular hexagonal groove is provided at the bottom end face of the fixing column of the mixing rotating fan.

[0006] Furthermore, each of the semi-circular heads of the rotating force plate is equipped with a rotating gripping rod via a bearing, and a fixing post is provided on the left end face of the rotating gripping rod.

[0007] Furthermore, a rotating force-bearing plate is inserted inside the regular hexagonal groove of the main bevel gear, a regular hexagonal prism is provided in the middle of the left end face of the rotating force-bearing plate, and semi-circular heads with left and right through holes are provided at both ends of the rotating force-bearing plate.

[0008] Furthermore, a main bevel gear is installed on the left side of the assembly hole of the assembly bearing plate via a bearing, and a fixing post is provided in the middle of the right end face of the main bevel gear. A regular hexagonal groove is opened on the right end face of the fixing post of the main bevel gear.

[0009] Furthermore, an assembly support plate is mounted on the fixed column of the bevel gear via a bearing. The assembly support plate is a U-shaped plate structure with an upward opening and a through-hole. A bearing hole that runs vertically through the bottom center of the assembly support plate is provided. A strip groove that runs upward through the middle of the left vertical plate of the assembly support plate is provided. An assembly hole that runs horizontally through the middle of the right vertical plate of the assembly support plate is provided.

[0010] Furthermore, a bevel gear is inserted into the hexagonal groove of the mixing rotary fan, a regular hexagonal prism is provided on the top end face of the bevel gear, and a fixing post is provided on the bottom end face of the bevel gear.

[0011] Compared with the prior art, the present invention has the following beneficial effects: The convenient mixing rotary fan is mounted on the powder mixing hopper via bearings and rotates synchronously with the bevel gear. This allows the powder mixing hopper to be easily removed at any time, solving the problem that the mixing hopper and support frame are integrated, making the disassembly and maintenance of the mixing hopper difficult and making it inconvenient to design the mixing hopper and support frame as separate parts for quick disassembly and maintenance.

[0012] The design facilitates the mounting of the main and secondary bevel gears on the assembly bearing plate via bearings, allowing them to mesh and transmit power. The rotation of the gripping rod and the rotating force plate allows the main and secondary bevel gears to mesh, driving the mixing rotary fan to rotate synchronously. This rotation of the mixing rotary fan mixes the powder inside the powder mixing tank, solving the problem that electrically driven mixing tanks have large capacities, making them unsuitable for mixing small quantities of metallurgical powders, and making it inconvenient to add manual mixing measures to the device to reduce the tank capacity for smaller mixing volumes.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0021] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown: This utility model provides a powder metallurgy mixing device that is easy to maintain, including a device body 1; the device body 1 is provided with a powder mixing tank 2 for convenient holding of metallurgical powder. The top outer circumference of the powder mixing tank 2 has a threaded annular groove for easy installation of a mixing sealing cover 3 via threads. A U-shaped handle is provided on the left side of the outer circumference of the powder mixing tank 2 for easy gripping and handling. A through bearing hole is provided in the center of the bottom wall of the powder mixing tank 2 for easy installation of a mixing rotary fan 4 via bearing. The mixing sealing cover 3 is threaded onto the annular groove of the powder mixing tank 2 for easy sealing of the powder mixing tank 2. The inner circumference of the mixing sealing cover 3 has threads for easy installation and removal via threads. The outer circumference of the mixing sealing cover 3 has an annular array of anti-slip grooves to facilitate rotation and prevent slippage of the mixing sealing cover 3. The bearing hole inside the powder mixing tank 2 is located at the top. The mixing rotary fan 4 is mounted on a bearing, facilitating its rotation. A support column is located at the center of the mixing rotary fan 4 to support the mixing plate. Mixing plates are arranged in a circular array around the support column, facilitating the mixing of metallurgical powders. A fixing column is located at the bottom of the support column, allowing the mixing rotary fan 4 to be mounted on the bearing. A regular hexagonal groove is formed at the bottom of the fixing column, allowing the hexagonal prism of the bevel gear 5 to be inserted for synchronous rotation. The bevel gear 5 is inserted into the hexagonal groove, facilitating its rotation. A regular hexagonal prism is located at the top of the bevel gear 5, facilitating its engagement with the hexagonal groove of the mixing rotary fan 4. A fixing column is located at the bottom of the bevel gear 5, facilitating the assembly of the support plate 6 via the bearing.

[0022] The assembly support plate 6 is mounted on the fixed column of the bevel gear 5 via bearings, facilitating the rotation of the bevel gear 5 through the bearings. The assembly support plate 6 is a U-shaped plate structure with an upward opening and a through-hole, allowing the powder mixing hopper 2 to be positioned inside. A through-hole bearing hole is located at the center of the bottom plate of the assembly support plate 6, facilitating the installation of the bevel gear 5 through the bearings. An upward-through-hole strip is located in the middle of the left vertical plate of the assembly support plate 6, allowing the U-shaped handle of the powder mixing hopper 2 to be positioned inside to prevent rotation. A through-hole assembly hole is located in the middle of the right vertical plate of the assembly support plate 6, facilitating the installation of the main bevel gear 7 through the bearings. The main bevel gear 7 is mounted on the left side of the assembly hole of the assembly support plate 6 via a bearing, facilitating the rotation of the main bevel gear 7 through the bearings. A fixing post is provided in the middle of the right end face of the main bevel gear 7 to facilitate the installation of the main bevel gear 7 via bearings. A regular hexagonal slot is opened on the right end face of the fixing post of the main bevel gear 7 to facilitate the insertion and synchronous rotation of the regular hexagonal prism of the rotating force plate 8. The rotating force plate 8 is inserted into the regular hexagonal slot of the main bevel gear 7 to facilitate the rotation of the main bevel gear 7. A regular hexagonal prism is provided in the middle of the left end face of the rotating force plate 8 to facilitate docking and synchronous rotation with the main bevel gear 7. Both ends of the rotating force plate 8 are provided with semi-circular heads with left and right through holes to facilitate the installation of the rotating gripping rod 9 via bearings. The rotating gripping rod 9 is installed on the semi-circular head of the rotating force plate 8 via bearings to facilitate hand gripping. A fixing post is provided on the left end face of the rotating gripping rod 9 to facilitate the installation of the rotating gripping rod 9 via bearings.

[0023] The specific usage and function of this embodiment are as follows: In this utility model, such as Figure 1 As shown, the device body 1 is in a ready-to-use state. At this time, the powder mixing barrel 2 contains powder material to be mixed, and the powder mixing barrel 2 is sealed by the mixing sealing cover 3. The U-shaped handle of the powder mixing barrel 2 is located inside the strip groove of the assembly support plate 6, thereby preventing the powder mixing barrel 2 from rotating through the strip groove of the assembly support plate 6. The hexagonal prism of the bevel gear 5 is inserted into the hexagonal groove of the mixing rotating fan 4, as shown in the figure. Figure 3 As shown, this allows the mixing rotary fan 4 and the bevel gear 5 to rotate synchronously. This plug-in assembly method solves the problem that the mixing tank and support frame are integrated, making the disassembly and maintenance of the mixing tank difficult. Figure 1As shown, when the device body 1 is mixing materials, the rotating gripper 9 is held to rotate the rotating force plate 8. The rotating force plate 8 rotates the main bevel gear 7 to mesh with the driven bevel gear 5, causing the driven bevel gear 5 to rotate through meshing. The rotation of the driven bevel gear 5 drives the mixing rotating fan 4 to rotate synchronously. Thus, the rotation of the mixing rotating fan 4 mixes the powder inside the powder mixing tank 2. This manual mixing method solves the problem that the electric-driven mixing tank has a large capacity and cannot be used for mixing small amounts of metallurgical powder. It is mostly used for mixing metallurgical powder less than 200 grams, and can also be used to mix metallurgical powder of tens of grams.

[0024] Example 2: The difference from Example 1 is that the outer circumferential surface of the mixing sealing cover 3 can also be set as a frosted surface, thereby increasing the friction between the outer circumferential surface of the mixing sealing cover 3 and the hand, and preventing the outer circumferential surface of the mixing sealing cover 3 from slipping when gripped.

[0025] Example 3: The difference from Example 1 is that the outer circumferential surface of the rotating grip bar 9 can also be set as a frosted surface, thereby increasing the friction between the outer circumferential surface of the rotating grip bar 9 and the hand, and preventing the outer circumferential surface of the rotating grip bar 9 from slipping when gripping the hand.
