Description

Technical Field

[0001] The invention relates to the field of shot blasting machines, in particular to an elliptical inner wall hook shot blasting machine. Background Art

[0002] Conventional hook shot blasting machines have a square horizontal cross-section of the inner wall, which not only requires a lot of materials and is costly to manufacture, but also the dead angles at the joints between the surfaces are easily damaged by the shot, causing perforation of the chamber. And because the cross-section of the inner wall is square, when the shot is ejected, unless it is aimed at the workpiece and hits it directly, it will hit the inner wall, and even the shot will reflect back and forth between the inner walls, which not only causes the loss of the shot, but also causes great wear on the inner wall, making it difficult to reflect the effective shot onto the workpiece. In addition, when the workpiece is cleaned by the ordinary hook shot blasting machine, the workpiece shakes due to the impact, and it is easy to avoid the effective ejection of the shot. Although the shot blasting time is long, the efficiency is low. .

[0003] Therefore, it is necessary to provide a new technical solution. Summary of the invention

[0004] In order to solve the technical problems existing in the prior art, the present invention discloses an elliptical inner wall hook shot blasting machine, and the specific technical scheme is as follows:

[0005] The present invention provides an elliptical inner wall hook shot blasting machine, comprising a shot blasting machine, a shot blasting machine mounting seat and an inner wall of a main chamber.

[0006] The shot blasting machine is installed on the shot blasting machine mounting seat, and a projectile point A is provided on the shot blasting machine;

[0007] The shot blasting machine mounting seat and the inner wall of the main chamber body are surrounded to form a shot blasting space, and a workpiece rotating area is provided in the shot blasting space, and the rotation center of the workpiece rotating area is point B;

[0008] The inner wall of the main chamber is in the shape of an ellipse with a portion of the long side end cut off.

[0009] Furthermore, the projection point A and the rotation center B are on the same horizontal plane.

[0010] Furthermore, the distance between the projectile point A and the rotation center B is M, and the range of M is 1300mm≤M≤1800mm.

[0011] Furthermore, the ejection point A and the rotation center B are two foci of the ellipse on which the inner wall of the main chamber is located.

[0012] Furthermore, the vertical plane of the straight line where the projection point A and the rotation center B are located divides the inner wall of the main chamber into left and right sides, any point on one side is point X, and any point on the other side is point Y, XA+XB=YA+YB.

[0013] The present invention has the following beneficial effects:

[0014] 1. The elliptical inner wall hook shot blasting machine provided by the present invention has an inner wall surface made of manganese steel plates integrally welded seamlessly, presenting an elliptical surface without any dead angles, simple maintenance and durability.

[0015] 2. The elliptical inner wall hook shot blasting machine provided by the present invention can reflect the balls hitting the inner wall surface by the elliptical inner wall surface, and all the balls can be reflected onto the workpiece, which greatly improves the shot blasting efficiency.

[0016] 3. In the elliptical inner wall hook shot blasting machine provided by the present invention, after the shot is projected onto the workpiece, although the workpiece will inevitably shake, as long as the amplitude of the shaking does not exceed the rotation center point, the shot that avoids the workpiece will be reflected by the inner wall surface and still hit the workpiece, thus greatly improving the utilization rate of the shot.

[0017] 4. The elliptical inner wall hook shot blasting machine provided by the present invention has an elliptical inner wall. Even if the balls are not reflected onto the workpiece, they will not be reflected back and forth between the inner walls, thus reducing unnecessary loss of the original shot materials.

[0018] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention provides an elliptical inner wall hook shot blasting machine, referring to Figure 1 , including a shot blasting machine 1, a shot blasting machine mounting seat 2 and an inner wall 3 of a main chamber.

[0026] The shot blasting machine 1 is mounted on the shot blasting machine mounting seat 2, and a projectile point A is set on the shot blasting machine 1. The shot blasting machine mounting seat 2 and the inner wall 3 of the main chamber body surround a shot blasting space, and a workpiece rotating area 4 is set in the shot blasting space, and the rotation center of the workpiece rotating area 4 is point B. The shape of the inner wall 3 of the main chamber body is an ellipse with a portion of the long side end cut off.

[0027] The projectile point A and the rotation center B are on the same horizontal plane.

[0028] Step 1, the distance between the projectile point A and the rotation center point B is M, and the range of M is 1300mm≤M≤1800mm.

[0029] The ejection point A and the rotation center B are two foci of the ellipse where the inner wall 3 of the main chamber is located.

[0030] The vertical plane of the straight line where the projection point A and the rotation center B are located divides the inner wall 3 of the main chamber into left and right sides, any point on one side is point X, and any point on the other side is point Y, XA+XB=YA+YB.

[0031] The working principle of the present invention is: the shot launching point A and the rotation center B of the workpiece are in a straight line along the ejection direction. In order to allow the steel shots that have not hit the workpiece to be reflected onto the workpiece through the inner wall surface, the inner wall surface needs to meet the following conditions: the horizontal cross-section of the straight line where the shot launching point A and the rotation center B of the workpiece are located, and the intersection line with the inner wall surface, that is, the ellipse line shown in the figure, any two points on this ellipse line satisfy: XA+XB=YA+YB (except the shaded area).

[0032] According to the design calculation and experiment, it is concluded that the distance M between the shot launching point A and the rotation center B of the workpiece needs to satisfy the following conditions: 1300mm≤M≤1800mm. When M<1300mm, the ejection distance is too small, the impact force on the workpiece is too large, and the workpiece shakes greatly, which can easily cause uneven surface treatment and color difference on the workpiece. When M>1800mm, the ejection distance is too far, and the shots are mostly secondary reflected strikes. The amount of shot in one strike is too small, and the shot cannot be well utilized.

[0033] During shot blasting, even if the workpiece shakes, the shot that avoids the workpiece will still pass through the inner wall and be reflected to the rotation center of the workpiece. Therefore, as long as the workpiece does not shake much and the amplitude does not exceed the rotation radius, it can be hit by the steel shot.

Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

A person skilled in the art may change, modify and vary the above embodiments within the scope of the present invention.
