Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal surface treatment, and in particular to a sheet metal surface treatment device. Background Art

[0002] Sandblasting is a common surface treatment process used to improve the roughness, cleanliness, and appearance of metal surfaces. Sandblasting removes impurities, rust, and old coatings from the metal surface by spraying abrasive particles (such as sand, glass beads, and steel shot) at high speeds, creating a uniform surface with a defined roughness, thus providing a good foundation for subsequent painting, welding, and other processes.

[0003] When cleaning sheet metal parts, existing sandblasting machines usually require workers to hold the sandblasting gun in one hand and the sheet metal part in the other hand, and perform multiple movements or rotations to ensure that the entire surface of the sheet metal part is effectively treated. Although this method can complete the sandblasting task to a certain extent, there are several problems in actual operation. First, operating the spray gun with one hand while holding the sheet metal part with the other hand makes the operation inconvenient, increases the complexity and difficulty of the operation, and thus prolongs the processing time. Second, frequent movement and rotation of the sheet metal part not only increases the operation time, but may also cause uneven operation, affecting the sandblasting effect. In addition, for heavier sheet metal parts, frequent movement and rotation will significantly increase the labor intensity of the workers. Long-term repetitive movements can easily cause operator fatigue and even cause occupational diseases. Especially when handling large or heavy sheet metal parts, workers need greater strength to maintain balance and control direction, which not only increases physical exertion, but may also cause damage to the sheet metal part or uneven sandblasting due to improper operation. These problems not only reduce work efficiency but also may affect the quality of the final product. Therefore, existing sandblasting machines have obvious deficiencies in terms of ease of operation and labor intensity.

The first sliding rod 11 and the top block 12 are connected between the two first connecting blocks 8. The first sliding rod 11 and the top block 12 are connected. The top block 12 is located on the right side of the inclined surface. When the top block 12 is pushed to the left, the top block 12 drives the first sliding rod 11 to move left. During this process, the top block 12 slides along the inclined surface on the first connecting block 8, causing the top block 12 to move to the left. As the top block 12 moves to the left, the first connecting block 8 will move up and down respectively, separating the fixing rings 9. The distance between the fixing rings 9 becomes larger. At this time, the first connecting spring 10 is compressed, releasing the lock on the universal ball 5.

[0021] like Figure 4 and Figure 5 As shown, it also includes a fixed block 14 and a second connecting spring 15. Four fixed blocks 14 are slidably connected to the placement plate 4. The fixed blocks 14 are arranged in a cross shape. The second connecting spring 15 is connected between the fixed block 14 and the placement plate 4 through a spring seat. The initial state of the second connecting spring 15 is a stretched state.

[0022] like Figure 4 and Figure 5 As shown, it also includes an oblique block 16, a second connecting block 17, a second slide rod 18, a connecting frame 19 and a third connecting spring 20. The fixed block 14 is connected to the oblique block 16, and the second connecting block 17 is symmetrically connected to the inner wall of the protective frame 1. The second connecting block 17 is connected to the second slide rod 18 in an up and down sliding manner. A connecting frame 19 is connected between the two second slide rods 18. The connecting frame 19 is located below the oblique block 16, and the connecting frame 19 is in contact with the fixed block 14. The third connecting spring 20 is connected between the connecting frame 19 and the second connecting block 17 through a spring seat.

[0024] like Figure 4 As shown, it also includes a fixed block 14 and a second connecting spring 15. Four fixed blocks 14 are slidably connected to the placement tray 4. The fixed blocks 14 are arranged in a cross shape. The second connecting spring 15 is connected between the fixed block 14 and the placement tray 4 through a spring seat. The initial state of the second connecting spring 15 is a stretched state; when the transparent cover 22 is rotated downward, when the transparent cover 22 touches the second slide bar 18, the second slide bar 18 will slide downward on the second connecting block 17, driving the connecting frame 19 to descend together. At this time, the third connecting spring 20 is compressed. As the connecting frame 19 descends, the second connecting spring 15 is no longer hindered, and it will push the inclined block 16 to move along the connecting frame 19 toward the center of the placement tray 4 until the inclined block 16 contacts the sheet metal and clamps the sheet metal.

[0025] like Figure 1 and Figure 2 As shown, it also includes a collecting frame 21 and a transparent cover 22. The collecting frame 21 is connected to the interior of the protective frame 1 in a front-to-rear sliding manner. The excess abrasive generated during the sandblasting process will fall into the collecting frame 21 through the filter screen, thereby realizing the recycling of waste materials, which not only reduces the burden of cleaning work, but also helps to save resources; a transparent cover 22 is hinged on the protective frame 1, and the sandblasting condition of the sheet metal parts can be observed through the transparent cover 22, which is convenient for manual observation of the completion of the sandblasting of the sheet metal parts.

[0026] When using this device, first place the sheet metal to be processed on the placement tray 4, then push the top block 12 to the left, and the top block 12 will drive the first slide bar 11 to move left. During this process, the top block 12 slides along the inclined surface on the first connecting block 8, causing the top block 12 to move to the left. As the top block 12 moves to the left, the first connecting block 8 will move up and down respectively, separating the fixing rings 9 and increasing the distance between the fixing rings 9. At this time, the first connecting spring 10 is compressed, releasing the lock on the universal ball 5. The position of the universal ball 5 is adjusted according to the specific size and thickness of the sheet metal to ensure that the nozzle of the automatic sandblasting machine 6 is in the most ideal sandblasting position, which can improve the adaptability and flexibility of the device. After the position of the nozzle of the automatic sandblasting machine 6 is adjusted, the reset top block 12 is moved to the right until the top block 12 returns to its initial position. At this time, the first connecting spring 10 will push the fixing ring 9 to reset, and the fixing ring 9 will lock the universal ball 5 again to fix the position of the automatic sandblasting machine 6. The fixing ring 9 is equipped with a rubber ring 13, which can effectively enhance the friction between the fixing ring 9 and the universal ball 5 to ensure the stable fixation of the universal ball 5; then, the transparent cover 22 is rotated downward, and when the transparent cover 22 touches the second slide bar 18, the second slide bar 18 will slide downward on the second connecting block 17, driving the connecting frame 19 to descend together. At this time, the third connecting spring 20 is compressed, and as the connecting frame 19 descends, the second connecting spring 15 is not When the transparent cover 22 is closed, the servo motor 3 and the automatic sandblasting machine 6 are started. During the operation of the automatic sandblasting machine 6, the servo motor 3 drives the sheet metal to rotate, ensuring that the automatic sandblasting machine 6 can evenly sandblast the sheet metal, thereby ensuring the quality of the sandblasting and effectively improving the working efficiency of the device. The sandblasting condition of the sheet metal can be observed through the transparent cover 22, which is convenient for manual observation of the sheet metal. The completion of the metal parts sandblasting; the excess abrasives generated during the sandblasting process will fall into the collection frame 21 through the filter screen, realizing the recycling of waste materials, which not only reduces the burden of cleaning work but also helps to save resources; after the sandblasting is completed, the transparent cover 22 is opened. As the transparent cover 22 is lifted, the third connecting spring 20 will push the connecting frame 19 to rise to its original position. During this process, the connecting frame 19 moves along the inclined surface of the inclined block 16, prompting the inclined block 16 to move outward synchronously, thereby releasing the clamping of the sheet metal. At this time, the operator can remove the sheet metal that has completed the sandblasting process and put in a new sheet metal, repeating the above steps to continue the sandblasting operation. After the work is completed, the equipment should be turned off and the device should be cleaned as necessary. It also includes a rubber ring 13, and the rubber ring 13 is connected to the side of the fixing ring 9 that is close to each other.
