Description

Technical Field

[0001] This utility model relates to the field of projectile rebound and diversion technology, specifically a multi-angle projectile rebound and diversion device for a shot blasting chamber. Background Technology

[0002] Shot blasting machines are widely used in the surface cleaning, rust removal, oxide removal, and surface strength treatment of metals, castings, and other workpieces. During shot blasting, the shot is accelerated by a high-speed rotating blasting wheel and propelled onto the workpiece surface. After impact, it bounces back and re-enters the blasting chamber for recirculation. To improve cleaning efficiency, especially for complex-shaped or large-area workpieces, maximizing the coverage area and bounce efficiency of the shot within the blasting chamber is crucial in the design.

[0003] Currently, most shot blasting machines have relatively simple designs for the rebound path and direction of the shot. The shot mainly rebounds along a fixed angle. This method often fails to achieve ideal cleaning results when dealing with workpieces with complex geometries. The limited range and angle of the shot's rebound result in some areas of the workpiece not being effectively cleaned, and some surfaces may even be inaccessible due to the angle, affecting cleaning quality and work efficiency.

[0004] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a multi-angle shot rebound and diversion device for shot blasting chambers. Utility Model Content

[0005] The purpose of this invention is to provide a multi-angle shot rebound and diversion device for a shot blasting chamber, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A technical solution for a multi-angle shot rebound and guide device for a shot blasting chamber includes a shot blasting chamber, the interior of which forms a shot blasting cavity. A collection hopper is provided at the bottom of the shot blasting cavity, and an inclined wall is provided on the side of the shot blasting chamber. An upper shot blasting machine and a lower shot blasting machine are symmetrically installed on the inclined wall, and both the upper and lower shot blasting machines are connected to the shot blasting chamber through material pipes. A cabinet door is provided on the front side of the shot blasting chamber, and the cabinet door is movably connected to the side wall of the shot blasting chamber through hinges. A plurality of rebound guide plates are fixedly installed on the inner wall of the shot blasting cavity, and two sets of rebound triangular prisms are arranged between the plurality of rebound guide plates.

[0008] As a preferred technical solution, the shot blasting directions of the upper shot blasting machine and the lower shot blasting machine are arranged at an angle.

[0009] As a preferred technical solution, a pivot is provided on the inner side of the cabinet door, and locking arms are connected to both ends of the pivot. A lock seat that cooperates with the locking arms is provided at the corresponding position on the side wall of the shot blasting chamber.

[0010] As a preferred technical solution, the rebound guide plates are continuously distributed circumferentially along the inner wall of the shot blasting cavity, and the rebound triangular prisms are arranged at intervals between the rebound guide plates.

[0011] As a preferred technical solution, the edge direction of the rebounding triangular prism is not perpendicular to the incident direction of the projectile, and the edge angle of each rebounding triangular prism is gradually distributed along the surface of the guide plate.

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

[0013] This invention relates to a multi-angle shot rebound and guiding device for a shot blasting chamber. The rebound guide plate and rebound triangular prism guide the shot to rebound at multiple angles within the chamber, effectively expanding the shot's coverage area and improving cleaning efficiency. By adjusting the angle and distribution of the rebound triangular prism's edges, precise control of the shot's rebound path can be achieved, ensuring the shot reaches every corner of the workpiece surface. This is particularly effective for workpieces with complex geometries. Furthermore, the shot blasting directions of the upper and lower shot blasting machines are arranged at an angle, further enhancing the shot's rebound effect and coverage area.

[0018] The features and exemplary embodiments of various aspects of this utility model will now be described in detail. To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide a further detailed description. For those skilled in the art, this utility model can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of this utility model by illustrating examples.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a technical solution for a multi-angle shot rebound and guiding device for a shot blasting chamber: it includes a shot blasting chamber 1, which has a shot blasting cavity 11. A collecting hopper 12 is provided at the bottom of the shot blasting cavity 11 for collecting the shot that rebounds and falls. An inclined wall 13 is provided on the side of the shot blasting chamber 1, and an upper shot blasting machine 21 and a lower shot blasting machine 22 are symmetrically installed on the inclined wall 13. Both the upper shot blasting machine 21 and the lower shot blasting machine 22 are connected to the shot blasting chamber 1 through a feed pipe 23, ensuring that the shot can be continuously blasted into the shot blasting cavity 11.

[0020] like Figure 2 As shown, a cabinet door 31 is provided on the front side of the shot blasting chamber 1. The cabinet door 31 is movably connected to the side wall of the shot blasting chamber 1 via a hinge 32, facilitating inspection and maintenance of the interior of the shot blasting chamber by operators. A pivot 33 is provided on the inner side of the cabinet door 31, with locking arms 34 connected to both ends of the pivot 33. A locking seat 35 that cooperates with the locking arms 34 is provided at a corresponding position on the side wall of the shot blasting chamber 1. This structural design allows the cabinet door 31 to be locked in the closed position, ensuring safety during the shot blasting process.

[0021] like Figure 3 As shown, several rebound guide plates 41 are fixedly installed on the inner wall of the shot blasting chamber 11. These rebound guide plates 41 are continuously distributed along the circumference of the inner wall of the shot blasting chamber 11. Two sets of rebound triangular prisms 42 are arranged between the rebound guide plates 41. These rebound triangular prisms 42 are arranged at intervals to guide the shot to rebound at multiple angles in the shot blasting chamber.

[0022] The shot blasting directions of the upper shot blasting machine 21 and the lower shot blasting machine 22 are arranged at an angle, which can further enhance the rebound effect and coverage of the shot.

[0023] The edges of the rebounding triangular prisms 42 are not perpendicular to the incident direction of the projectile, and the edge angles of each rebounding triangular prism 42 are gradually distributed along the surface of the guide plate 41. This design makes the rebound path of the projectile more diversified in the shot blasting chamber 1, thereby effectively expanding the coverage area of ​​the projectile and improving the cleaning efficiency.

[0024] Through the above structural design, the multi-angle shot rebound guiding device of this utility model can guide the shot to rebound at multiple angles within the shot blasting chamber, effectively expanding the shot coverage area and improving cleaning efficiency. The cleaning effect is even more significant for workpieces with complex geometries. Simultaneously, the shot blasting directions of the upper and lower shot blasting machines are arranged at an angle, further enhancing the shot rebound effect and coverage area. The rotating shaft and locking arm structure located inside the cabinet door facilitates opening and closing the door, making maintenance and cleaning of the shot blasting chamber convenient. This utility model has the advantages of simple structure, convenient operation, and good cleaning effect, and is suitable for surface cleaning of various metals, castings, and other workpieces.
