[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] See also Figure 1-Figure 5 The air blasting machine of embodiment 1 is a kind of air blasting machine for producing and processing metal castings, comprises a shot blasting machine body 1 and a cover body 2 installed above the shot blasting machine body 1, the upper surface of the outer wall of the cover body 2 is connected with a blowing mechanism and a diversion assembly, the output end of the blowing mechanism is connected with one end of the diversion assembly, the other three ends of the diversion assembly are connected with a connecting pipe 7, the other ends of the three connecting pipes 7 pass through the outer wall of the cover body 2, and are respectively fixedly connected with a horizontal pipe 8 and two vertical pipes 9. The upper surface of the inner wall of the cover body 2 is fixedly connected with two L-shaped plates 10, a sliding rod 12 is fixedly connected between the two L-shaped plates 10, and the outer wall of the sliding rod 12 is connected to two supporting assemblies, one side of the two supporting assemblies is connected with an adjusting assembly, the lower ends of the two supporting assemblies are respectively connected with one end of the two vertical pipes 9, the two ends of the horizontal pipe 8 are respectively connected with the inner wall of the two L-shaped plates 10 away from the end of the sliding rod 12, and the outer walls of the horizontal pipe 8 and the two vertical pipes 9 are fixedly connected with a number of nozzles 11.

[0025] The shot blasting machine for metal casting production and processing in the present invention is similar in structure to the existing shot blasting machine, such as the shot blasting machine disclosed in the patent publication number CN220145675U. Figures 1 to 5 As shown, the shot blasting machine for metal casting production and processing in the present invention processes the surface of the metal casting through the shot blasting machine body 1, and at the same time, the blowing mechanism is started by an external controller (or the controller of the shot blasting machine body 1 itself, because the controller is an existing mature technology, it is not described in detail). After the blowing mechanism is started, it will continuously supply air to the inside of the diversion component, and then the gas will be diverted to three connecting pipes 7 through the diversion component, and then enter a horizontal pipe 8 and two vertical pipes 9 respectively, and finally a plurality of nozzles 11 will spray towards the surface of the metal casting, and then the shot particles remaining on the surface of the metal casting can be blown off, thereby avoiding affecting the subsequent processing procedures due to the residual shot particles, and even causing the workpiece quality to be unqualified.

[0026] Because different metal castings have different widths and thicknesses, the spray angles of the nozzles 11 on the horizontal pipe 8 and the two vertical pipes 9 need to be adjusted according to the different metal castings. At this time, before treating the surface of the metal castings, the position and angle of the nozzle 11 can be adjusted through the support assembly and the adjustment assembly, which is simple and easy to operate.

[0027] like Figure 1-Figure 3 As shown, the blowing mechanism includes an air pump 3 and an air pipe 4. The outer wall of the air pump 3 is fixedly connected to the upper surface of the outer wall of the cover body 2, the output end of the air pump 3 is fixedly connected to one end of the air pipe 4, and the other end of the air pipe 4 is connected to the diversion component.

[0028] More specifically, when it is necessary to blow air onto the surface of the metal casting, it is only necessary to turn on the air pump 3 through the controller. After the air pump 3 is started, it will continue to supply air, and the supplied gas will enter the diversion component through the air pipe 4 for diversion.

[0029] like Figure 1-Figure 3 As shown, the diversion assembly includes a four-way pipe 5 and a support rod 6. The lower end of the support rod 6 is fixedly connected to the upper surface of the outer wall of the cover body 2, and the upper end of the support rod 6 is fixedly connected to the outer wall of the four-way pipe 5. The four ends of the four-way pipe 5 are respectively fixedly connected to the air supply pipe 4 and the three connecting pipes 7.

[0030] More specifically, when gas flows inside the gas pipe 4 , the gas will enter the cross-tube 5 , and then be diverted to the three connecting pipes 7 through the cross-tube 5 until it enters the horizontal pipe 8 and the two vertical pipes 9 .

[0031] It should be noted that the support rods 6 can support the cross-tube 5 and keep the cross-tube 5 stable.

[0032] like Figure 3-Figure 5 As shown, the support assembly includes an L-shaped block 14, a connecting block 15 and a threaded rod 16. One end of the L-shaped block 14 is sleeved and slidably connected to the outer wall of the slide rod 12, the other end of the L-shaped block 14 is sleeved and fixedly connected to the upper end of the connecting block 15, the lower end of the connecting block 15 is sleeved and slidably connected to the outer wall of the threaded rod 16, one end of the threaded rod 16 is fixedly connected to one end of the vertical pipe 9, and one side of the upper end of the L-shaped block 14 is connected to the adjustment assembly.

[0033] More specifically, the support assembly can provide support for the two vertical pipes 9 so that they can keep blowing air onto the surface of the metal casting without shaking.

[0034] like Figure 3 and Figure 5 As shown, the adjustment assembly includes a knob 13 and an anti-slip ring 18. An anti-slip groove 1401 is provided on one side of the L-shaped block 14. The anti-slip ring 18 is located in the anti-slip groove 1401, and the outer wall of the anti-slip ring 18 is rotatably connected to the inner wall of the anti-slip groove 1401. The outward side of the anti-slip ring 18 is fixedly connected to one side of the knob 13. The knob 13 is sleeved and threadedly connected to the outer wall of the slide rod 12.

[0035] More specifically, when the position of the vertical pipe 9 needs to be adjusted, it is only necessary to turn the knob 13, and the knob 13 can be rotated inside the anti-slip groove 1401 through the anti-slip ring 18. At the same time, the knob 13 moves threadedly on the surface of the sliding rod 12, thereby moving the supporting assembly (i.e., the L-shaped block 14, the connecting block 15 and the threaded rod 16) and the vertical pipe 9 together.

[0036] like Figure 3 and Figure 5As shown, the outer wall of the slide rod 12 is provided with a plurality of slide grooves 1201 , the inner wall of the upper end of the L-shaped block 14 is fixedly connected with a plurality of slide bars 19 , and the outer walls of the plurality of slide bars 19 are slidably connected with the inner walls of the plurality of slide grooves 1201 .

[0037] More specifically, by providing the sliding groove 1201 and the sliding bar 19 , the L-shaped block 14 can be prevented from rotating on the surface of the sliding rod 12 , thereby preventing the stability of the vertical pipe 9 from being affected.

[0038] like Figure 4 As shown, the threaded rod 16 is sleeved on the outer wall of the connecting block 15 on the side close to the vertical pipe 9 and is fixedly connected to the top block 20. The threaded rod 16 is sleeved on the outer wall of the connecting block 15 on the side away from the vertical pipe 9 and is threadedly connected to the No. 1 nut 17.

[0039] More specifically, by providing the top block 20 and the No. 1 nut 17, firstly, the stability of the connection of the vertical pipe 9 inside the connecting block 15 can be ensured; secondly, when the jet angle of the vertical pipe 9 needs to be adjusted, it is only necessary to loosen the No. 1 nut 17, then rotate the vertical pipe 9, adjust the angle, and then tighten it with the No. 1 nut 17.

[0040] like Figure 3 As shown, both ends of the outer wall of the transverse tube 8 are fixedly connected with limiting rods 21, and the outer walls of the two limiting rods 21 are slidingly connected with the inner walls of the two L-shaped plates 10 respectively. One of the limiting rods 21 passes through the outer wall of one end of the L-shaped plate 10 and is threadedly connected with a No. 2 nut 22.

[0041] More specifically, by providing the limiting rod 21 and the No. 2 nut 22 , when the jetting angle of the transverse pipe 8 needs to be changed, the No. 2 nut 22 can be loosened and then tightened.

[0042] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
