Description

Technical Field

[0001] The utility model relates to an air pipe tool for powder cleaning, belonging to the technical field of powder cleaning equipment. Background Art

[0002] The skin lattice structure is an ideal material for satellite structural panels. It consists of two layers of thin-walled skin and a regularly arranged lattice structure in the middle. Figure 1 As shown in the figure, the skin lattice structure can be created by 3D printing and investment casting technology, which has the advantages of short production cycle and low cost. It can be mass-produced, and the maximum size of the molding has exceeded 2 meters.

[0003] The first process step is to make a wax mold and use 3D printing technology to print the PMMA board with skin lattice structure. After the 3D printing is completed, the loose powder also fills the cavity. It is necessary to remove the equipment from the shell and clean the loose powder inside the PMMA board.

[0004] At present, most of the PMMA powder cleaning process in China is operated by workers, and the quality of powder cleaning depends on the workers' skill level. In the process of operation, it often happens that the brush does not vertically enter the grid structure during powder cleaning, causing the brush to collide with the rod, thus causing the rod to break and causing the workpiece to be scrapped. Therefore, we proposed a trachea tooling for powder cleaning. Utility Model Content

[0005] The utility model aims to provide an air pipe tooling for powder cleaning, so as to solve the problems of broken rods and uncontrollable air blowing during powder cleaning, reduce production costs and improve powder cleaning efficiency.

The small diameter end of the main body is arranged on the inner side of the trachea, and a plurality of guide plates are distributed on the side surface of the main body. The plurality of guide plates are arranged around the axis of the main body. The large diameter end of the main body is fixed to the inner wall of the trachea through the guide plate, that is, the upper part of the side surface of the guide plate away from the axis of the main body is connected to the inner wall of the trachea, and the main body is fixed in the inner cavity of the trachea through the guide plate, and the central axis of the main body and the trachea are in the same straight line.

[0008] The aforementioned air pipe tooling for powder cleaning, the side surface of the guide plate away from the main body axis is curved, and the side surface of the guide plate away from the main body axis gradually approaches the inner wall of the air pipe from bottom to top, so that the lower end of the guide plate shrinks inward to facilitate the gas to enter the channel between the guide plates, the top of the guide plate is close to the air pipe and fits tightly, and the gas between the guide plates is ejected along the extension direction of the channel between the guide plates, and the airflows converge at the outlet to form turbulence.

[0009] The aforementioned air pipe tooling for cleaning powder has a diverter short plate arranged between two adjacent guide plates, the diverter short plate is arranged on the side wall of the main body, and the side of the diverter short plate away from the axis of the main body is fixed to the inner wall of the air pipe. The diverter short plate once again diverts and guides the airflow in the channel between the two guide plates, thereby increasing the amount of airflow at the outlet and further ensuring that airflow passes in all directions.

[0010] In the aforementioned air pipe tool for powder cleaning, the guide plate is twisted along the circumference of the main body to facilitate the formation of turbulent flow.

[0011] In the aforementioned air pipe tooling for powder cleaning, the extension direction of the diversion short plate is consistent with that of the guide plate.

[0012] The aforementioned air pipe tool for powder cleaning also includes a tool frame, which is provided with a plurality of through holes arranged in a straight line, and an air pipe is inserted and fixed in each through hole. The end of the air pipe not equipped with a guide impeller passes through the through hole and is connected to the air supply equipment.

[0013] The aforementioned air pipe tooling for powder cleaning also includes two limit plates, which are arranged parallel to each other on both sides of the air pipe along the arrangement direction of the multiple air pipes, and one end of the air pipe provided with a guide impeller is placed in the middle of the two limit plates. The workpiece that needs powder cleaning can be placed between the two limit plates for easy positioning and use.

[0014] Compared with the prior art, the utility model has at least the following beneficial effects:

[0015] (1) The utility model adopts air blowing to replace the manual brush method to clean the powder, thus avoiding the problem of damage to the workpiece caused by the brush colliding with the rod;

[0016] (2) When the utility model is used, the compressed air passes through the impeller and disperses different airflows, forming turbulence from the outlet, which can ensure that airflow passes in all directions and blow away the powder adhering to the workpiece, and the powder cleaning effect is good and the efficiency is high;

[0017] (3) The powder cleaning air pipe of the utility model is fixed on the tooling frame to ensure that the air pipe is placed vertically. At the same time, the limit plate assists the PMMA board in positioning. The PMMA board moves back and forth along the air pipe direction to ensure that the powder inside the board is cleaned. The operation is simple and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS
