Description

Technical Field

[0001] The utility model belongs to the technical field of sandblasting processing of stainless steel castings, and particularly relates to a sandblasting device for stainless steel castings. Background Art

[0002] Stainless steel castings refer to stainless steel parts made by casting process. Casting is a metal forming technology in which molten metal is poured into a mold and solidified into the desired shape after cooling. Stainless steel is widely used in the casting field due to its good corrosion resistance, strength and machinability. It is especially suitable for manufacturing parts that withstand harsh environmental conditions, such as chemical equipment, food processing machinery and medical equipment components. The sandblasting device of stainless steel castings is a device used for surface treatment. It cleans, strengthens or textures the surface of steel parts by spraying abrasives (such as corundum, glass beads, steel shots, etc.) at high speed. Sandblasting can remove impurities such as scale, molding sand, rust, carbon deposits and welding slag on the surface of castings, and at the same time improve the surface roughness and increase the adhesion of coating or subsequent processing. The existing sandblasting device of stainless steel castings has a fixed angle of the sandblasting head, which brings the disadvantage of uneven surface treatment.

[0003] For example, the utility model with announcement number CN209665138U discloses a sandblasting device for stainless steel processing. In this patent scheme, the angle of the sandblasting head is fixed. The fixed-angle sandblasting head may not be able to effectively reach all parts of the workpiece, especially the corners and recessed areas of complex geometric shapes, resulting in incomplete sandblasting and affecting the overall quality. The unchanged angle means that some areas may receive excessive or insufficient sandblasting, resulting in uneven surface treatment effect. Utility Model Content

[0004] In view of this, the utility model aims to provide a sandblasting device for stainless steel castings to address the deficiencies in the prior art. The sandblasting head can adjust the angle, allowing the operator to more flexibly and effectively treat surfaces of different shapes and angles, including hard-to-reach areas. It can also ensure that the workpiece surface obtains a uniform and consistent treatment effect, thereby improving the surface quality and aesthetics.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a sandblasting device for stainless steel castings, including a sandblasting box, the front side of the sandblasting box is hinged with a box plate through a hinge, a handle is arranged on the front side of the box plate, and slide rails are arranged on the left and right sides of the inner wall of the sandblasting box, and two sliding blocks are slidably connected inside the two slide rails, and cavity frames are rotatably connected between the two adjacent sliding blocks on the left and right through rotating columns, and sandblasting heads are arranged in multiple sandblasting holes evenly opened at the lower ends of the two cavity frames, and sand conveying pipes are arranged in the sand conveying holes opened at the upper ends of the two cavity frames, and a An adjustment mechanism for adjusting the angle of the sandblasting head, a clamping mechanism is arranged on the left and right sides of the sandblasting box, the adjustment mechanism includes a bidirectional screw arranged inside the left slide rail, two sliding blocks located inside the left slide rail are respectively threadedly connected to the front and rear corresponding ends of the bidirectional screw, gears are fixedly sleeved on the outer arc surface of the rotating column, a rack plate is arranged at the upper end of the interior of the sandblasting box, two gears are meshed and connected with a rack plate, an electric drive unit for driving the bidirectional screw to rotate is arranged at the left end of the rear side of the sandblasting box, the electric drive unit includes a motor arranged at the left end of the rear side of the sandblasting box, and the output shaft of the motor is connected to the rear end of the bidirectional screw through a coupling.

[0006] As a further improvement of the utility model, a collecting box is slidably arranged at the lower end of the interior of the sandblasting box, and a second handle is arranged on the front side of the collecting box.

[0007] As a further improvement of the utility model, the clamping mechanism includes electric push rods arranged on the left and right sides of the sandblasting box, and clamping plates are arranged on the telescopic ends of the two electric push rods.

[0008] As a further improvement of the utility model, two support plates corresponding to left and right positions are arranged at the lower end of the sandblasting box, and two mounting holes are arranged inside the two support plates.

[0009] As a further improvement of the utility model, a control panel is arranged on the front side of the sandblasting box, and the electric push rod and the motor are both electrically connected to the control panel.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] Firstly, by connecting the sand conveying pipe to the external sand pumping mechanism, the personnel then pull open the box plates, and then place the stainless steel castings that need to be sandblasted between the two clamping plates, and then control the control panel to turn on the electric push rod, and the telescopic end drives the clamping plates on both sides to move closer together to clamp the stainless steel castings, and then the hose opens the external sand pumping mechanism, and the sand enters the cavity frame from the sand conveying pipe and is sprayed out from the nozzle, so that the stainless steel castings can be sandblasted quickly.

[0012] Secondly, the motor is turned on through the control panel, and the output shaft drives the bidirectional screw to rotate, so that the sandblasting heads on the internal sliding block move closer or farther away from each other. At the same time, the gears on the rotating column are affected by the meshing relationship of the rack plate, so that the sandblasting head of the cavity frame tube rotates back and forth, realizing multi-angle back and forth sandblasting of stainless steel castings. The sandblasting head can adjust the angle, which allows the operator to more flexibly and effectively process surfaces of different shapes and angles, including hard-to-reach areas, and ensure that the workpiece surface obtains a uniform and consistent treatment effect, thereby improving the surface quality and aesthetics.

[0013] Thirdly, the installation holes on the support plate can be used to quickly and conveniently fix the sandblasting device in a suitable position, making the operation of the sandblasting device more stable.

[0014] Fourthly, the sand that is not sprayed onto the stainless steel castings falls into the collection box, and personnel can draw it out through handle two for recycling. BRIEF DESCRIPTION OF THE DRAWINGS
