Description

Technical Field

[0001] The utility model belongs to the technical field of sandblasting treatment of casting accessories, in particular to a sandblasting tool for casting accessories. Background Art

[0002] Casting accessories are a kind of workpiece produced by casting. Different from accessories produced by stamping, lathe and milling, cast accessories are not only relatively strong, but also mostly special-shaped structural accessories with complex shapes and structures. This type of accessories is difficult to process and shape by stamping or lathe milling.

[0003] During the casting process, the first step is to prepare the mold, such as the wax mold. After casting, demoulding is performed, and then the accessories are subjected to various treatments, such as polishing, grinding, sandblasting, etc. Among them, sandblasting is a key step in the processing of casting accessories. Sandblasting can improve the anti-corrosion ability of casting accessories.

[0004] According to the size of the workpiece, sandblasting is mostly divided into open-air sandblasting and sandblasting in a sandblasting machine. During the sandblasting process, the position of the workpiece needs to be constantly adjusted to ensure that the surface of the workpiece can be sandblasted. However, in the actual sandblasting process, especially for small workpieces with a large number and small size, it is impossible to sandblast one by one during the sandblasting process (first, it is inconvenient to position the workpiece, second, it is inconvenient to adjust the posture of the workpiece during sandblasting, and third, the workpiece size is small and the operability is relatively poor). Therefore, currently small workpieces can only be placed together and sandblasted together.

[0005] However, a difficult-to-solve technical problem is that a large number of small accessories are placed together. During the sandblasting process, firstly, each accessory cannot be fully sandblasted because the accessories are piled together. Secondly, during the sandblasting process, the workpiece cannot be moved to adjust its posture to facilitate the complete sandblasting of the workpiece surface. Utility Model Content

[0039] Example 1

[0040] like Figure 1-7As shown, a sandblasting tool for casting accessories includes a sandblasting outer protective tube 1 (the purpose is to prevent a large amount of sandblasting from escaping into the air), and a sandblasting chamber 4 is rotatably connected inside the sandblasting outer protective tube 1. Specifically, the front and rear ends of the sandblasting chamber 4 are respectively fixedly connected with a rotating shaft, and the rotating shaft is rotatably connected to the sandblasting outer protective tube 1 (according to the existing method, the sandblasting outer protective tube 1 is installed on the workbench); and a rotating motor 3 is assembled and connected to the rotating shaft at the rear side. The method is the same as the existing method. The rotating motor 3 is installed on the rear side wall of the sandblasting outer protective tube 1, and its output shaft is connected to the rotating shaft (the sandblasting outer protective tube 1 is installed with a bearing adapted to the rotating shaft). At the same time, a long feed port 42 is opened on the left side wall of the sandblasting chamber 4, and a feed port corresponding to the long feed port 42 is opened on the sandblasting outer protective tube 1. According to the existing conventional method, a sealing cover (not shown in the figure) is threadedly connected to the feed port. Before sandblasting, loosen the sealing cover and put the workpiece into the sandblasting chamber 4 along the material port and the long feed port 42. During the sandblasting process, control the rotating motor 3 to drive the sandblasting chamber 4 to rotate at an angle between 0 and 60 degrees, and prevent the workpiece from falling from the long feed port 42.

[0041] The overall shape of the sandblasting chamber 4 is a rectangle, the purpose of which is to utilize the rectangle to greatly flip the workpiece during the flipping process, and to achieve a large-range posture flipping of the workpiece during the process of flipping from one side to the other vertical side.

[0042] At the same time, in order to improve the turning effect of the workpiece during the sandblasting process and avoid the workpieces from piling up and failing to be sandblasted sufficiently, a swing plate mechanism is installed and connected in the sandblasting chamber 4. During the sandblasting process, the workpiece changes its posture through the swing plate mechanism. In addition, the swing plate mechanism is used to swing and pull the workpiece to avoid the workpieces from being piled up together.

[0043] Specifically, the above-mentioned swing plate mechanism includes a plurality of first swing plate members assembled and connected at the bottom position of the sandblasting chamber 4 (the first swing plate members are evenly distributed and spaced apart on the left and right sides of the bottom position of the sandblasting chamber 4) and a plurality of second swing plate members assembled and connected on the vertical side walls inside the sandblasting chamber 4 (specifically, on the right side wall of the sandblasting chamber 4).

[0044] The specific structure of the first pendulum plate is as follows:

[0045] The first swing plate members all include a first swing plate 43, and the bottom of the first swing plate 43 is fixedly connected with a plurality of first springs A fixedly connected to the sandblasting chamber 4. The advantage of the spring design is that during the flipping of the sandblasting chamber 4, the first swing plate 43 follows the flipping, and because the first swing plate 43 is connected through the first spring A, the first swing plate 43 swings under the swinging of the spring, so that the accumulated workpieces can be pushed apart by the swinging method, and the workpieces can be easily pushed and adjusted in posture, so as to fully sandblast the surface of the workpieces.

[0046] Similarly, the second swing plate member includes a second swing plate 44, and a plurality of second springs fixedly connected to the sandblasting chamber 4 are fixedly connected to the second swing plate 44. When the sandblasting chamber 4 is flipped to the side wall position where the second swing plate 44 is located, the workpiece is continued to be swung and pulled in the same manner, thereby improving the sandblasting effect of the workpiece.

[0047] Example 2

[0048] like Figure 1-7 As shown, based on the structure of Example 1, in order to avoid the first swing plate 43 swinging too much, resulting in too large a spacing between adjacent first swing plates 43, the workpiece is easy to fall into the spacing between the first swing plates 43 (in the initial state, the spacing between the first swing plates 43 is smaller than the size of the workpiece, to prevent a large number of workpieces from falling between the first swing plates 43, and similarly, the second swing plates 44 are set with the same spacing). Both ends of each of the above-mentioned first swing plates 43 are provided with a plurality of first limit through holes 431, and a first gear rod 432 is provided between the first limit through holes 431, and both ends of the first gear rod 432 are fixedly connected to the inner wall of the sandblasting chamber 4.

[0049] During the working process, when the rotating sandblasting chamber 4 rotates, the first swing plate 43 pulls and flips the workpiece in the above manner, and because the first swing plate 43 is limited on the first gear rod 432, although the first limiting through hole 431 has a certain width, the first gear rod 432 is used to prevent the first swing plate 43 from swinging too much.

[0050] Similarly, second limiting through holes are formed at both ends of the second swing plate 44 ; a second gear rod 441 runs through the second limiting through holes, and both ends of the second gear rod 441 are fixedly connected to the side walls of the sandblasting chamber 4 on both sides.

[0051] Example 3

[0052] like Figure 1-7 As shown, this embodiment is based on the structure of the embodiment 1. The sandblasting tooling for casting accessories also includes a sandblasting tube mechanism 2. During the sandblasting process, the sandblasting tube mechanism 2 blasts sand into the sandblasting chamber 4.

[0053] Specifically, the sandblasting tube mechanism 2 includes a sandblasting tube rack, which includes an outer tube rack portion 21 located outside the sandblasting outer protective tube 1, and the outer tube rack portion 21 is integrally formed with a through-tube rack portion 22 that penetrates the sandblasting outer protective tube 1, and the through-tube rack portion 22 penetrates the sandblasting chamber 4; a horizontal sandblasting tube rack portion 23 is integrally formed at the bottom of the through-tube rack portion 22, and the horizontal sandblasting tube rack portion 23 is located in the sandblasting chamber 4, and a plurality of sandblasting nozzles 24 are connected to the bottom of the horizontal sandblasting tube rack (wherein the sandblasting nozzle 24 is a nozzle for a conventional sandblasting gun disclosed in the prior art).

[0054] Specifically, the front and rear sides of the top of the sandblasting chamber 4 are respectively provided with adjustment ports 41 corresponding to the through-tube frame portion 22. During the swinging process of the sandblasting chamber 4, the through-tube frame portion 22 swings relative to the adjustment ports 41. By designing the adjustment ports 41, the sandblasting tube frame is not blocked during the rotation of the sandblasting chamber 4, and the horizontal sandblasting tube frame is located at the upper position in the sandblasting chamber 4, and the sandblasting nozzle 24 is kept facing downward. The height is controlled well to ensure that the swinging of the sandblasting chamber 4 is not hindered.

[0055] The outer tube frame 21 is connected with an interface pipe. According to the conventional method, the outer tube frame 21 is connected to the pipeline of the sandblasting equipment through the interface pipe, and the high-pressure sand material sprayed by the sandblasting machine is sprayed from the sandblasting nozzle 24 to perform efficient sandblasting on the workpiece.

[0056] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
