Description

Technical Field

[0001] This utility model relates to the field of casting surface treatment technology, specifically a casting surface treatment sandblasting machine. Background Technology

[0002] A sandblasting machine is a mechanical device that uses compressed air to propel abrasive materials (metallic and non-metallic) onto the surface of a workpiece. It works by using compressed air to transport powdery granular material from one point to another within a pipeline. During this process, kinetic energy is converted into potential energy, causing the high-speed moving sand particles to scour the surface of the object, thereby improving its surface quality.

[0003] Currently, existing sandblasting machines typically place the castings statically in the working chamber when sandblasting the surface of castings. This makes it difficult to achieve a complete sandblasting of the casting surface. The castings also need to be removed and flipped for sandblasting, which is inefficient. Furthermore, the sand spreads everywhere during sandblasting, making it difficult to collect and resulting in a waste of sand.

[0004] Therefore, we propose a sandblasting machine for surface treatment of castings. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solution: a sandblasting machine for surface treatment of castings, comprising a working box, a casting support mechanism, a sandblasting mechanism and a collection and circulation mechanism, wherein the casting support mechanism comprises a fixed seat fixedly installed on the bottom wall of the working box, a worktable rotatably installed on the fixed seat, and a first motor for driving the worktable to rotate;

[0007] The sandblasting mechanism includes a sand box, a sandblasting pump, an elastic corrugated pipe, a nozzle, and an adjustment component for controlling the raising and lowering of the nozzle. The sand box and the sandblasting pump are both fixedly installed on the top of the working box. The inlet pipe of the sandblasting pump is connected to the sand box, and the outlet pipe of the sandblasting pump extends into the working box and is connected to the elastic corrugated pipe. The nozzle is connected to the lower end of the elastic corrugated pipe.

[0008] The collection and circulation mechanism includes a collection box, a collection pipe, a suction nozzle, a filter screen, a mounting frame, a fan blade, a drive assembly, and a circulation pipe.

The suction nozzles are evenly arranged on the collection pipe. The filter screen and the mounting frame are both fixedly installed inside the sand box. The mounting frame is located above the filter screen. The fan blade is rotatably installed on the mounting frame. The drive assembly is used to drive the fan blade to rotate. The circulation pipe connects the collection box and the sand box.

[0009] Preferably, the adjustment assembly includes a second motor, a vertical screw, a lifting block, and a bracket. The second motor is fixedly installed on the top of the working box, and the output end of the second motor is fixedly connected to the upper end of the vertical screw.

During sandblasting, the first motor can be started to drive the worktable to rotate, so that the worktable drives the casting to rotate, which facilitates the comprehensive sandblasting of the casting.

[0017] 2. This utility model, by setting up a collection and circulation mechanism, allows the drive component to rotate the fan blades during sandblasting. The fan blades generate airflow, creating a negative pressure state inside the collection pipe, causing the suction nozzle to absorb sand from the air. The sand passes through the collection pipe into the collection box, where a filter screen filters the sand, keeping it within the collection box. This reduces sand splashing and air pollution. Once a certain amount of sand has been collected in the collection box, the valve can be opened to discharge the sand from the circulation pipe into the sand box, achieving sand recycling and reducing sand waste.

[0029] This utility model provides a technical solution:

[0030] Please see Figures 1-5 A sandblasting machine for surface treatment of castings includes a working box 1, a casting support mechanism 2, a sandblasting mechanism 3 and a collection and circulation mechanism 4. The front of the working box 1 is hinged with a door 11, and a viewing window 12 is installed on the door 11 to facilitate observation of the sandblasting situation inside the working box 1.

[0031] Specifically, the casting support mechanism 2 includes a fixed base 21 fixedly installed on the bottom wall of the work box 1, a worktable 22 rotatably installed on the fixed base 21, and a first motor 23 for driving the worktable 22 to rotate. By setting the casting support mechanism 2, the casting to be processed can be fixed on the worktable 22 using a clamp. During sandblasting, the first motor 23 can be started to drive the worktable 22 to rotate, so that the worktable 22 drives the casting to rotate, which facilitates the comprehensive sandblasting of the casting.

[0032] Specifically, the sandblasting mechanism 3 includes a sand tank 31, a sandblasting pump 32, an elastic corrugated pipe 33, a nozzle 34, and an adjustment component 35 for controlling the raising and lowering of the nozzle 34. The sand tank 31 and the sandblasting pump 32 are both fixedly installed on the top of the working box 1. The inlet pipe of the sandblasting pump 32 is connected to the sand tank 31, and the outlet pipe of the sandblasting pump 32 extends into the working box 1 and is connected to the elastic corrugated pipe 33. The nozzle 34 is connected to the lower end of the elastic corrugated pipe 33. By setting the sandblasting mechanism 3, during sandblasting, the sandblasting pump 32 can be started to transport the sand in the sand tank 31 to the elastic corrugated pipe 33. After passing through the elastic corrugated pipe 33, the sand enters the nozzle 34 and is sprayed out from the nozzle 34. At the same time, the raising and lowering of the nozzle 34 can be controlled by the adjustment component 35 so that the nozzle 34 can uniformly sandblast the casting.

[0033] Specifically, the adjustment assembly 35 includes a second motor 351, a vertical screw 352, a lifting block 353, and a bracket 354. The second motor 351 is fixedly installed on the top of the working box 1, and the output end of the second motor 351 is fixedly connected to the upper end of the vertical screw 352. The vertical screw 352 is rotatably installed inside the working box 1. The lifting block 353 is sleeved on the vertical screw 352 and threadedly connected to the vertical screw 352. The bracket 354 is fixedly connected to one side of the lifting block 353. The nozzle 34 is detachably installed on the bracket 354. The adjustment assembly 35 also includes... The system includes two guide rails 355 fixedly installed inside the work box 1. The two guide rails 355 are arranged parallel to each other on both sides of the vertical screw 352. The lifting block 353 is slidably connected to the guide rails 355. By setting the adjustment component 35, during the sandblasting process, the second motor 351 can be started to drive the vertical screw 352 to rotate, so that the vertical screw 352 drives the lifting block 353 to move vertically along the vertical screw 352. The lifting block 353 drives the nozzle 34 to rise and fall through the bracket 354, thereby adjusting the position of the nozzle 34 and improving the uniformity of sandblasting.

[0034] Specifically, the collection and circulation mechanism 4 includes a collection box 41, a collection pipe 42, a suction nozzle 43, a filter screen 44, a mounting frame 45, a fan blade 46, a drive assembly 47, and a circulation pipe 48. The collection box 41 is fixedly installed on the top of the sand box 31. The collection pipe 42 is fixedly connected to one side of the collection box 41, with its lower end extending into the working box 1. The suction nozzles 43 are evenly distributed on the collection pipe 42. The filter screen 44 and the mounting frame 45 are both fixedly installed inside the sand box 31, with the mounting frame 45 positioned above the filter screen 44. The fan blade 46 is rotatably mounted on the mounting frame 45. The drive assembly 47 drives the fan blade 46 to rotate. The circulation pipe 48 connects the collection box 41 and the sand box 31, circulating... A valve 481 is installed on the ring pipe 48. By setting up a collection and circulation mechanism 4, during the sandblasting process, the drive component 47 drives the fan blade 46 to rotate. After the fan blade 46 generates airflow, it creates a negative pressure state in the collection pipe 42, causing the suction nozzle 43 to absorb sand from the air. The sand enters the collection box 41 through the collection pipe 42. The filter screen 44 filters the sand, keeping it in the collection box 41. This reduces the amount of sand splashed around and reduces sand pollution to the air. When a certain amount of sand is collected in the collection box 41, the valve 481 can be opened to discharge the sand in the collection box 41 from the circulation pipe 48 into the sand box 31, realizing the recycling of sand and reducing sand waste.

[0035] Specifically, the drive assembly 47 includes a housing 471, a third motor 472, a first rotating shaft 473, a first bevel gear 474, and a second bevel gear 475. The housing 471 is fixedly installed on one side of the collection box 41, the third motor 472 is fixedly installed inside the housing 471, the first rotating shaft 473 is fixedly installed at the output end of the third motor 472, and the other end of the first rotating shaft 473 extends into the collection box 41 and is coaxially connected to the first bevel gear 474. The second bevel gear 475 is coaxially connected to the fan blade 46 and meshes with the first bevel gear 474. By setting the drive assembly 47, when driving the fan 46, the third motor 472 can be started to drive the first rotating shaft 473 to rotate, which in turn drives the first bevel gear 474 to rotate, which in turn drives the second bevel gear 475 to rotate, which in turn drives the fan blade 46 to rotate.

[0036] Furthermore, the drive assembly 47 also includes a cam 476 disposed above the filter screen 44 and a second rotating shaft 477 fixedly connected to one side of the cam 476. A drive wheel 478 is fixedly mounted on the first rotating shaft 473, and one end of the second rotating shaft 477 extends into the housing 471 and is fixedly mounted with a driven wheel 479. The drive wheel 478 and the driven wheel 479 are linked by a belt. By setting up the cam 476, the second rotating shaft 477, the drive wheel 478, and the driven wheel 479, when collecting sand, the first rotating shaft 473 will drive the drive wheel 478 to rotate, and the drive wheel 478 will drive the driven wheel 479 to rotate via the belt. The driven wheel 479 will drive the second rotating shaft 477 to rotate, and the rotation of the second rotating shaft 477 will drive the cam 476 to rotate, so that the convex end of the cam 476 will continuously strike the filter screen 44, which can shake off the sand adhering to the filter screen 44, reduce the clogging of the filter screen 44 by sand, and facilitate the collection of sand.

[0037] First, the casting to be processed can be fixed on the workbench 22 using a clamp. Then, the box door 11 is closed, and the sandblasting pump 32 is started to transport the sand in the sand box 31 to the elastic corrugated pipe 33. After passing through the elastic corrugated pipe 33, the sand enters the nozzle 34 and is sprayed out from the nozzle 34.

[0038] During sandblasting, the first motor 23 can be started to drive the worktable 22 to rotate, causing the worktable 22 to rotate the casting. At the same time, the second motor 351 can be started to drive the vertical screw 352 to rotate, causing the vertical screw 352 to drive the lifting block 353 to move vertically along the vertical screw 352. The lifting block 353 drives the nozzle 34 to rise and fall through the bracket 354, thereby adjusting the position of the nozzle 34, improving the uniformity of sandblasting, and facilitating comprehensive sandblasting of the casting.

[0039] Next, during the sandblasting process, the drive component 47 can drive the fan blade 46 to rotate. After the fan blade 46 generates airflow, it creates a negative pressure state in the collection pipe 42, causing the suction nozzle 43 to absorb sand from the air. The sand enters the collection box 41 through the collection pipe 42, and the filter screen 44 filters the sand, keeping it in the collection box 41. This reduces the amount of sand splashed around and reduces sand pollution to the air. When a certain amount of sand is collected in the collection box 41, the valve 481 can be opened to discharge the sand in the collection box 41 from the circulation pipe 48 into the sand box 31, realizing the recycling of sand.

[0040] In summary, this casting surface treatment sandblasting machine, by setting up a casting support mechanism 2, a sandblasting mechanism 3, and a collection and circulation mechanism 4, can perform comprehensive sandblasting on castings, improve work efficiency, and can also recycle the sprayed sand, reducing sand waste.

[0041] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
