Description

Technical Field

[0001] This utility model relates to the field of powder mixing devices, and in particular to a powder mixing device for wear-resistant weld overlay alloy powder. Background Technology

[0002] Cemented carbide is an alloy material made from hard compounds of refractory metals and a binder metal through powder metallurgy. It is widely used as a cutting tool material, such as turning tools, end mills, planing tools, drill bits, and boring tools, for cutting cast iron, non-ferrous metals, plastics, synthetic fibers, graphite, glass, stone, and ordinary steel. It can also be used to cut difficult-to-machine materials such as heat-resistant steel, stainless steel, high-manganese steel, and tool steel. Cemented carbide powder requires mixing during the production and processing.

[0003] A search revealed a Chinese patent publication number CN222368839U disclosing a high-efficiency mixing device for alloy powder. This patent includes a tank assembly containing a mixing component. The tank assembly comprises a mixing tank and a mixing chamber. The mixing chamber is located within the mixing tank, and an opening is located at the top center of the mixing tank. This device controls two arc-shaped agitators to reciprocate horizontally. This reciprocating motion moves the inner and outer layers of alloy powder within the mixing chamber, and also moves alloy powder located at the edge of the mixing chamber to the agitator blades, resulting in more uniform mixing and improved powder mixing efficiency and quality. However, current alloy powder mixing devices suffer from several drawbacks. During mixing, powder at different heights is difficult to move vertically, leading to reduced mixing uniformity. Furthermore, alloy powder at the bottom edge tends to solidify, hindering the overall mixing effect. During feeding, some powder adheres to the bottom of the mixing cylinder, resulting in slow feeding speed. Therefore, a wear-resistant, weld-hardened alloy powder mixing device is needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a wear-resistant weld overlay alloy powder mixing device to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A wear-resistant weld overlay alloy powder mixing device includes a base plate, two symmetrically arranged supports fixedly connected to the base plate, mounting sleeves fixedly connected to the supports, and a powder mixing mechanism mounted on the mounting sleeves.

The vibration mechanism includes a lifting plate slidably disposed within the base plate, a rotating disk rotatably connected to the bottom of the lifting plate, and a drive assembly for driving the rotating disk to rotate relative to the lifting plate. Several mounting columns are fixedly connected to the bottom of the rotating disk. The vibration mechanism also includes a fixing ring fixedly connected to the center of the bottom of the base plate, located directly below the mounting columns, and several guide blocks fixedly connected to the top of the fixing ring.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figure 1 — Figure 6 As shown, a wear-resistant weld overlay alloy powder mixing device includes a base plate 101. Two symmetrically arranged supports 102 are bolted to the base plate 101. Mounting sleeves 103 are bolted to the supports 102, and a mixing mechanism is mounted on the mounting sleeves 103. The mixing mechanism includes a mixing cylinder 201. A mounting shaft 202 is bolted to the top side of the mixing cylinder 201 and rotatably connected to the mounting sleeve 103. A discharge pipe 203 is fixedly mounted on the side of the mixing cylinder 201. The connection between the feed pipe 203 and the mixing cylinder 201 is a flared structure. A hopper 205 is bolted to the top of the mixing cylinder 201. A valve body 204 is installed on the discharge pipe 203. A stirring mechanism is installed on the mixing cylinder 201, and a vibration mechanism is installed inside the mixing cylinder 201. The vibration mechanism includes a lifting plate 401, which is slidably disposed within the base plate 101. A rotating disk 402 is rotatably connected to the bottom of the lifting plate 401. The vibration mechanism also includes a drive assembly for driving the rotating disk 402. The rotating disc 402 rotates relative to the lifting plate 401. Several mounting posts 409 are welded to the bottom of the rotating disc 402. The vibration mechanism also includes a fixed ring 406, which is bolted to the center of the bottom of the base plate 101. The fixed ring 406 is located directly below the mounting posts 409. Several guide blocks 407 are bolted to the top of the fixed ring 406. The guide blocks 407 are wedge-shaped with their inclined surfaces facing upwards. The bottom of the guide blocks 407 extends to be flush with the top of the fixed ring 406 and extends along the edge of the fixed ring 406. The 6-sided surface gradually rises, and the side furthest from the bottom of the fixing ring 406 is set as a vertical surface. When the mounting column 409 rotates with the rotating disk 402, under the guidance of the guide block 407, the mounting column 409 can periodically lift the rotating disk 402, thereby causing the lifting plate 401 to move up and down. In conjunction with the stirring mechanism, it can play a vertical mixing role for the alloy powder of each layer. A traction mechanism is set on the mounting column 409 away from the bottom plate 101. The traction mechanism is used to drive the mixing cylinder 201 to tilt and discharge the material.

[0026] In this embodiment, the drive assembly includes a second motor 403. A mounting bracket 405 is bolted to the bottom of the base plate 101. The second motor 403 is bolted to the mounting bracket 405. The output shaft of the second motor 403 is connected to a drive rod 404 via a coupling. The drive rod 404 is inserted into the rotating disk 402. When the second motor 403 starts, it drives the drive rod 404 to rotate. When the drive rod 404 rotates, it can drive the rotating disk 402 to rotate through its cooperation with the rotating disk 402. And when the rotating disk 402 moves up and down, it can always drive the rotating disk 402 to rotate.

[0027] In this embodiment, the bottom of the lifting plate 401 is connected by bolts to several annularly distributed spring assemblies 408, which can provide a certain buffering effect for the lifting plate 401.

[0028] In this embodiment, the pulling mechanism includes an electric push rod 501, which is bolted to the top of the base plate 101. The output end of the electric push rod 501 is bolted to a translation frame 502, which is slidably connected to the top of the base plate 101. A pulling rod 503 is bolted to the bottom of the mixing cylinder 201, and a connecting rod 504 is bolted to the pulling rod 503. The connecting rod 504 is sleeved within the translation frame 502. After the alloy powder in the base plate 101 is mixed, the mixed powder needs to be discharged. During discharge... The output end of the electric push rod 501 is retracted, and the electric push rod 501 drives the translation frame 502 to move closer to the electric push rod 501. The translation frame 502 drives the mixing cylinder 201 to tilt through the connecting rod 504 and the pulling rod 503, so that the discharge pipe 203 on the mixing cylinder 201 is tilted downward and the collection device is placed below the discharge pipe 203. The valve body 204 is opened and the second motor 403 is kept in the open state. Under the action of the reciprocating motion of the lifting plate 401, the powder that has been mixed is facilitated to accelerate the discharge of powder and the discharge is thorough.

[0029] In this embodiment, the stirring mechanism includes a primary motor 301, which is bolted to the top of the mixing cylinder 201. The output end of the primary motor 301 is connected to a main shaft 302 via a coupling, and several stirring rods 303 are bolted to the side of the main shaft 302.

[0030] Working Principle: In the initial state of use, the mixing cylinder 201 is vertical and the valve 204 is closed. The alloy powder to be mixed is fed into the mixing cylinder 201 from the hopper 205. Motors 1 and 2 are then turned on. Motor 301 drives the stirring rod 303 to rotate via the main shaft 302, mixing the alloy powder. When motor 403 starts, it drives the drive rod 404 to rotate. The drive rod 404, in conjunction with the rotating disk 402, drives the rotating disk 402 to rotate. As the rotating disk 402 rotates, the mounting post 409 at its bottom moves along the fixed ring 406 and is guided by the guide block 407, periodically lifting the rotating disk 402 and the lifting plate 401, causing the lifting plate 401 to reciprocate. This movement, combined with the stirring rod 301, causes the alloy powder to mix. 3. It can accelerate the movement between the upper and lower layers of alloy powder, which is beneficial to accelerate mixing and has better mixing uniformity. When the rotating disk 402 and the lifting plate 401 move up and down, the drive rod 404 can always drive the rotating disk 402 to rotate. When the mixing operation is completed, when discharging, the output end of the electric push rod 501 is controlled to retract. The electric push rod 501 drives the translation frame 502 to move closer to the electric push rod 501. The translation frame 502 drives the mixing cylinder 201 to tilt through the connecting rod 504 and the pulling rod 503, so that the discharge pipe 203 on the mixing cylinder 201 is tilted downward and the collection device is placed below the discharge pipe 203. The valve body 204 is opened and the second motor 403 is kept in the open state. Under the action of the reciprocating motion of the lifting plate 401, the powder that has been mixed is conducive to accelerating the discharge of powder and the discharge is more thorough.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
