Description

Technical Field

[0001] This utility model relates to the technical field of powder material processing equipment, and more specifically to a zirconium powder spreading workbench. Background Technology

[0002] In aerospace applications such as turbine blade thermal barrier coating pre-application, powder bed preparation in 3D printing, micron-level circuit silver paste coating in electronic packaging, catalyst coating application in new energy fuel cells, and scientific research experiments, uniform zirconium powder application is a critical process. Currently, existing zirconium powder application equipment mostly employs pneumatic spraying, vibrating screens, or electrostatic application. Among these, pneumatic spraying equipment has a complex structure, high equipment and maintenance costs, and stringent requirements for zirconium powder particle size and flowability, making it prone to clogging. While vibrating screen application is relatively simple in structure, it is difficult to achieve precise control of the application amount, resulting in poor application uniformity and failing to meet high-precision process requirements. Electrostatic application equipment, on the other hand, has high environmental requirements and is susceptible to external electromagnetic interference.

[0003] In practical applications, existing spreading equipment either struggles to balance spreading accuracy and efficiency, or its complex structure leads to inconvenient operation and high costs, making it difficult to meet the diverse and precise spreading needs of zirconium powder in different scenarios. There is an urgent need for a zirconium powder spreading device that is simple in structure, cost-controllable, and can achieve high precision and uniform spreading. Utility Model Content

[0004] The purpose of this invention is to provide a zirconium powder spreading workbench to improve the accuracy of zirconium powder spreading and achieve uniform spreading.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A zirconium powder spreading workbench includes a workbench with a mounting frame on the workbench. A mounting frame is mounted on the top of the mounting frame. Two placement plates are symmetrically fixed above the mounting frame. A discharge plate is fixed above the two placement plates. A discharge hopper is mounted on the top of the discharge plate, and a discharge port is opened at the bottom of the discharge hopper. Multiple discharge holes are opened on the discharge plate opposite to the discharge port. A sliding groove is opened on the top of each of the two placement plates on opposite sides. A movable plate is provided between the two placement plates. The two sides of the movable plate are slidably connected to the sliding groove. Multiple through holes are opened on the movable plate, each corresponding to a discharge hole. A mounting plate is fixed on one side of the mounting frame, and a discharge cylinder is mounted on the mounting plate, driving the movable plate.

[0007] Furthermore, a first cylinder and a second cylinder are respectively provided at both ends of the workbench. The first cylinder is driven and connected to a first limiting plate, and the second cylinder is driven and connected to an L-shaped baffle. The first limiting plate and the L-shaped baffle are arranged opposite to each other.

[0008] Furthermore, a third cylinder is installed on one side of the bottom upper surface of the L-shaped baffle, and the third cylinder drives a third limiting plate, which is perpendicular to the first limiting plate.

[0009] Furthermore, dust covers are provided on the outer sides of the first cylinder, the second cylinder, and the third cylinder.

[0010] Furthermore, a vibrator is installed on the outside of the discharge hopper.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] In this application, the discharge holes of the discharge plate correspond one-to-one with the through holes of the moving plate. The moving plate is driven to slide by the discharge cylinder to achieve periodic alignment and misalignment of the discharge holes and through holes, thereby accurately controlling the amount and timing of zirconium powder spreading. Compared with the traditional vibrating screen method, the spreading accuracy is significantly improved. Attached Figure Description

[0017] like Figures 1 to 3As shown, a zirconium powder spreading workbench includes a workbench 1, a mounting frame 2 on the workbench 1, a mounting frame 3 on the top of the mounting frame 2, two placement plates 4 symmetrically fixed above the mounting frame 3, a discharge plate 5 fixedly fixed above the two placement plates 4, a discharge chamber 6 on the top of the discharge plate 5, a discharge port at the bottom of the discharge chamber 6, multiple discharge holes 501 on the discharge plate 5 opposite to the discharge port, a sliding groove 401 on the top of each opposite side of the two placement plates 4, a movable plate 7 between the two placement plates 4, the two sides of the movable plate 7 slidably connected to the sliding groove 401, multiple through holes on the movable plate 7, each through hole corresponding to a discharge hole 501, a mounting plate 8 fixedly fixed on one side of the mounting frame 3, a discharge cylinder 9 mounted on the mounting plate 8, and the discharge cylinder 9 driving the movable plate 7.

[0018] The workbench 1 is equipped with a first cylinder 10 and a second cylinder 11 at its two ends. The first cylinder 10 is connected to a first limiting plate 12, and the second cylinder 11 is connected to an L-shaped baffle 13. The first limiting plate 12 and the L-shaped baffle 13 are arranged opposite to each other. By driving the first limiting plate 12 with the first cylinder 10 and the L-shaped baffle 13 with the second cylinder 11, the workpiece can be fixed in both directions, ensuring the stability of the workpiece position during the spreading process and improving the spreading accuracy and consistency.

[0019] A third cylinder 14 is installed on one side of the bottom upper surface of the L-shaped baffle 13. The third cylinder 14 drives a third limiting plate 15, which is perpendicular to the first limiting plate 12. The third cylinder 14 drives the third limiting plate 15 to be perpendicular to the first limiting plate 12, thereby increasing the positioning effect of the workpiece.

[0020] Dustproof covers 16 are provided on the outer sides of the first cylinder 10, the second cylinder 11 and the third cylinder 14.

[0021] A vibrator is installed on the outside of the discharge hopper 6; the vibrator can effectively prevent zirconium powder from agglomerating or bridging in the discharge hopper 6, ensuring that the zirconium powder falls smoothly and improving the uniformity and continuity of the spreading.

[0022] Working principle:

[0023] Zirconium powder is stored in the discharge hopper 6 and falls through the bottom discharge port to the discharge hole 501 of the discharge plate 5. The discharge cylinder 9 drives the moving plate 7 to slide within the chute 401. When the through hole on the moving plate 7 aligns with the discharge hole 501, the zirconium powder falls and is spread; when they are misaligned, the spreading stops. By controlling the stroke and speed of the discharge cylinder 9, the amount and area of ​​zirconium powder spread can be precisely controlled. At the same time, the first cylinder 10, the second cylinder 11, and the third cylinder 14 drive the first limiting plate 12, the L-shaped baffle 13, and the third limiting plate 15 respectively to fix the workpiece, while the vibrator ensures the fluidity of the zirconium powder in the discharge hopper.

[0024] This invention achieves precise alignment of the discharge hole and the through hole through a mechanical structure, and improves the accuracy of zirconium powder spreading by combining precise control of the cylinder.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
