Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically to a sheet metal surface treatment device. Background Technology

[0002] Sheet metal surface treatment processes are mainly used to clean the sheet metal surface and improve its aesthetics, such as sandblasting. Sandblasting is a commonly used process in sheet metal surface treatment. It uses compressed air to spray abrasive at high speed onto the sheet metal surface, creating a uniformly rough sandy surface. This can improve the appearance of the sheet metal surface and enhance coating adhesion. In current sandblasting processes, the operator usually holds the sandblasting gun in one hand and the workpiece in the other.

[0003] Currently, a sheet metal surface treatment device with announcement number CN218312924U includes a mounting box. The mounting box has a fixed column inside, a support plate above the fixed column, and a bearing installed in the center of the support plate. A placement platform is rotatably mounted in the center of the bearing. Two sets of magnetic plates, connected to the placement platform and arranged at equal angles around the center of the support plate, are located near the edge of the support plate. By energizing one set of magnetic plates above the support plate, a repulsive magnetic field is generated between the two sets of magnetic plates, causing the magnetic plates to rotate the placement platform. The rotation of the placement platform causes the sheet metal part to rotate, and two spray guns simultaneously perform sandblasting on the sheet metal part. After the upper part of the sheet metal part is sandblasted, simply reversing the sheet metal part once is sufficient to sandblast the entire surface of the sheet metal part, thus improving the surface treatment efficiency and reducing labor intensity.

[0004] While existing sandblasting processes rely on handheld sheet metal handling for movement and rotation, this method is labor-intensive and can lead to hand fatigue during prolonged work. Although existing solutions can replace manual handling of sheet metal parts with structural components, the sandblasting process generates a large amount of fine and metallic debris. Furthermore, the gaps between the baffle and the collar in these solutions, necessary for platform rotation, allow debris to enter the structure, increasing cleaning difficulty. The magnetic drive of the structure further attracts metal debris, exacerbating the problem. Therefore, a suitable device is urgently needed to address the issue of the large amount of debris generated during sandblasting operations. Utility Model Content

[0005] Based on the above description, this utility model provides a sheet metal surface treatment device to solve the problem that when existing surface treatment devices process sheet metal parts, the generated debris easily enters the interior of the structure, thereby increasing the difficulty of cleaning.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A sheet metal surface treatment device includes a treatment box, a grid plate and a sandblasting module are provided inside the treatment box, and an upper cover is hinged to the treatment box by a hinge, and two gloves are provided inside the upper cover.

[0007] The grid plate is equipped with a positioning mechanism, and the two gloves are symmetrically distributed with the positioning mechanism as the center.

[0008] The positioning mechanism includes a vertical rod detachably connected to the grid plate, a rotating disk rotatably connected to the top of the vertical rod, two symmetrical blocks symmetrically distributed on the rotating disk, a clamping component on the symmetrical block, an elastic component and a blocking component between the clamping component and the symmetrical block, and the elastic component is located inside the blocking component.

[0009] The above technical solution enables the sheet metal parts placed on the rotating disk to be clamped and positioned by the cooperation between the elastic element and the clamping element; while the shielding element protects the connection between the structures, thereby preventing debris from entering the structure and reducing the difficulty of cleaning the overall device.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the top of the upright is rotatably connected to the bottom of the rotating disk via a damping shaft. The rotating disk is circular, and the upright is located at the center of the rotating disk.

[0012] The above technical solution enables the rotating disk to rotate between the uprights, requiring a certain external force to push it. On the one hand, it can avoid excessive rotation during the sandblasting process, which would affect the sandblasting work. On the other hand, it makes it convenient to adjust the rotation of the rotating disk by hand, making the processing work more convenient.

[0013] Furthermore, two guide holes are provided on the symmetrical block, and the clamping member includes two guide rods that pass through and are slidably connected in the corresponding guide holes, with a limiting block provided at the end of the guide rod away from the upright;

[0014] The inner wall of the guide hole and the outer side of the guide rod are both smooth. A clamping plate is provided between the two guide rods near the end of the upright, and the clamping plate is V-shaped.

[0015] The above technical solution enables the guide rod to move smoothly within the guide hole, thereby driving the clamping plate to clamp and position the sheet metal part.

[0016] Furthermore, the shielding component includes four protective sleeves disposed on the symmetrical block, with two protective sleeves on each side of the symmetrical block, and the side of the protective sleeves away from the symmetrical block being connected to the outer side of the limiting block and the clamping plate, respectively.

[0017] The above technical solution enables the protective cover to provide shielding and protection.

[0018] Furthermore, the guide rod is located inside the corresponding protective sleeve, and the outer side of the protective sleeve has an annular corrugated structure and the inner side is cylindrical.

[0019] The above technical solution enables the protective sleeve to shield and protect the structural connection of the guide rod.

[0020] Furthermore, the elastic element includes two compression springs disposed on the symmetrical block, the compression springs being located on the side of the symmetrical block away from the upright, and the side of the compression springs away from the symmetrical block being connected to the outer side of the corresponding limiting block.

[0021] The compression spring is located inside the corresponding protective sleeve and outside the corresponding guide rod.

[0022] Through the above technical solution, the compression spring can provide elastic force when it deforms, thereby achieving the effect of elastic positioning; the protective sleeve can shield and protect the outside of the compression spring.

[0023] Furthermore, the bottom of the rotating disk is provided with a shielding cylinder and a connecting cylinder, both of which are open at the top and bottom, and the inner diameter of the shielding cylinder is larger than the inner diameter of the connecting cylinder.

[0024] A sealed bearing is provided between the inner side of the connecting cylinder and the outer side of the upright. The sealed bearing is located below the damping shaft, and the shielding cylinder is located on the outer side of the connecting cylinder.

[0025] Through the above technical solutions, the shielding cylinder can provide a certain degree of protection for the outside of the connecting cylinder, preventing debris splashed from the outside from moving directly onto the connecting cylinder; the setting of the sealed bearing can further protect the layout of the damping shaft.

[0026] Furthermore, a connecting hole is provided between the front and top of the upper cover, and a transparent plate is provided inside the connecting hole. The transparent plate is L-shaped.

[0027] The above technical solution allows operators to easily observe the process through a transparent panel.

[0028] Furthermore, a collection box is slidably connected inside the processing box, the top of the collection box is open, and the front of the processing box has a removal hole for the collection box to be removed.

[0029] The length of the collection box is greater than the length of the grid plate, and the width of the collection box is greater than the width of the grid plate.

[0030] The above technical solution enables the collection box to collect debris that falls from the grid plate.

[0031] Furthermore, the sandblasting module includes a feed pipe located outside the processing box and a sandblasting gun placed on the grid plate, with a PTFE spring tube between the sandblasting gun and the feed pipe.

[0032] The above technical solution allows the sandblasting medium to be delivered into the sandblasting gun for blasting via the feed pipe and PTFE spring tube.

[0033] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0034] 1. The protective sleeve effectively shields and protects the structural connections of the compression spring, symmetrical block, and guide rod, thus preventing debris and metal shavings from entering the connections. The compression spring and clamping plate work together to hold and position the sheet metal parts placed on the rotating plate, facilitating sandblasting. Under gravity, debris accumulates in the processing box and is easily swept into the collection box by the grid plate, making surface treatment of sheet metal parts convenient and simplifying the final cleaning process.

[0035] 2. Under the constraint of gravity, the sandblasted debris and metal shavings will fall downwards. The shielding cylinder prevents the sandblasted debris and metal shavings from moving to the outside of the connecting cylinder, thus protecting the rotating connection. The sealed bearing inside the connecting cylinder provides further protection, effectively protecting the connection between the upright and the rotating disk. Attached Figure Description

[0047] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0049] Example: Reference Figure 1 and Figure 2 A sheet metal surface treatment device includes a treatment box 1, a grid plate 2 and a sandblasting module 8 inside the treatment box 1, a top cover 4 hinged to the treatment box 1, and two gloves 5 inside the top cover 4; a positioning mechanism 3 is provided on the grid plate 2, and the two gloves 5 are symmetrically distributed around the positioning mechanism 3; the positioning mechanism 3 includes a vertical rod 31 detachably connected to the grid plate 2, a rotating disk 32 rotatably connected to the top of the vertical rod 31, two symmetrical blocks 33 symmetrically distributed on the rotating disk 32, a clamping member on the symmetrical block 33, and an elastic member and a blocking member between the clamping member and the symmetrical block 33, with the elastic member located inside the blocking member.

[0050] refer to Figure 7The top of the upright 31 is rotatably connected to the bottom of the rotating disk 32 via a damping shaft. The rotating disk 32 is circular, and the upright 31 is located at the center of the rotating disk 32, allowing the rotating disk 32 to rotate between the upright 31 and the rotating disk 32. A certain amount of external force is required to push it. On the one hand, this can prevent excessive rotation during the sandblasting process from affecting the sandblasting work. On the other hand, it makes it convenient to adjust the rotation of the rotating disk 32 by hand at a small angle, making the processing work more convenient.

[0051] refer to Figure 4 and Figure 5 Two guide holes are provided on the symmetrical block 33. The clamping component includes two guide rods 34 that pass through and slide in the corresponding guide holes. A limiting block 35 is provided at the end of the guide rod 34 away from the upright 31. The limiting block 35 can limit the guide rod 34. The inner wall of the guide hole and the outer side of the guide rod 34 are both smooth. A clamping plate 37 is provided between the ends of the two guide rods 34 that are close to the upright 31. The clamping plate 37 is V-shaped, which allows the guide rod 34 to move smoothly in the guide hole, thereby driving the clamping plate 37 to clamp and position the sheet metal part. The top of the clamping plate 37 is arc-shaped, which allows the sheet metal part to move downward through the arc-shaped part of the top of the clamping plate 37, making it easier to clamp and position it through the clamping plate 37.

[0052] refer to Figure 5 and Figure 6 The shielding component includes four protective sleeves 38 disposed on the symmetrical block 33. Two protective sleeves 38 are disposed on each side of the symmetrical block 33. The side of the protective sleeve 38 away from the symmetrical block 33 is connected to the outer side of the limiting block 35 and the clamping plate 37 respectively. The protective sleeves 38 can achieve the effect of shielding and protection.

[0053] refer to Figure 5 The guide rod 34 is located inside the corresponding protective sleeve 38. The outer side of the protective sleeve 38 has an annular corrugated structure and the inner side is cylindrical, so that the protective sleeve 38 can shield and protect the structural connection of the guide rod 34. The annular corrugated design allows the protective sleeve 38 to fold appropriately as the guide rod 34 and the limiting block 35 move.

[0054] refer to Figure 5The elastic element includes two compression springs 36 disposed on the symmetrical block 33. The compression springs 36 are located on the side of the symmetrical block 33 away from the upright 31. The side of the compression springs 36 away from the symmetrical block 33 is connected to the outer side of the corresponding limiting block 35. Whether compressed or stretched, the compression springs 36 can provide a rebound force when deformation occurs, thereby achieving the effect of elastic compression positioning. The compression springs 36 are located inside the corresponding protective sleeve 38 and outside the corresponding guide rod 34. The protective sleeve 38 can shield and protect the outer side of the compression springs 36, and the guide rod 34 can guide the compression springs 36 so that they can stably undergo elastic deformation.

[0055] refer to Figure 6 and Figure 7 The bottom of the rotating disk 32 is provided with a shielding cylinder 39 and a connecting cylinder 310. The top and bottom of the shielding cylinder 39 and the connecting cylinder 310 are open. The inner diameter of the shielding cylinder 39 is larger than the inner diameter of the connecting cylinder 310. The shielding cylinder 39 can provide a certain degree of protection for the outside of the connecting cylinder 310, preventing debris from flying directly onto the connecting cylinder 310. A sealed bearing is provided between the inner side of the connecting cylinder 310 and the outer side of the upright 31. The sealed bearing is located below the damping shaft, and the shielding cylinder 39 is located outside the connecting cylinder 310. The setting of the sealed bearing can further protect the installation point of the damping shaft.

[0056] It should be noted that the debris and metal shavings generated by sandblasting will initially fly around. The shielding cylinder 39 can block the flying debris and prevent it from moving directly to the outside of the connecting cylinder 310. After the sandblasting is complete, the debris will fall naturally under the action of gravity. At this time, the shielding cylinder 39 can restrict the debris to its outside and prevent it from entering the structure.

[0057] refer to Figure 1 and Figure 2 The top cover 4 has a connecting hole between the front and the top, and a transparent plate 6 is installed inside the connecting hole. The transparent plate 6 is L-shaped, which allows the operator to easily observe during operation.

[0058] refer to Figure 1 A collection box 7 is slidably connected inside the processing box 1. The top of the collection box 7 is open. The front of the processing box 1 has a removal hole for the collection box 7 to be moved out. The length of the collection box 7 is greater than the length of the grid plate 2, and the width of the collection box 7 is greater than the width of the grid plate 2, so that the collection box 7 can collect the debris falling from the grid plate 2 for unified processing.

[0059] refer to Figure 2 and Figure 3The sandblasting module 8 includes a feed pipe 82 located outside the processing box 1 and a sandblasting gun 81 placed on the grid plate 2. The feed pipe 82 is connected to a container for storing sandblasting media. A PTFE spring tube 83 is provided between the sandblasting gun 81 and the feed pipe 82. The sandblasting media can be transported into the sandblasting gun 81 for blasting through the feed pipe 82 and the PTFE spring tube 83.

[0060] It should be noted that the sandblasting process of the sandblasting gun 81 is a commonly used technique in existing sheet metal surface treatment technology, so it will not be elaborated on further.

[0061] In use, open the top cover 4, move the sheet metal part onto the rotating disk 32, open the clamping plate 37 to stretch the compression spring 36, and then move the sheet metal part between the two clamping plates 37 on opposite sides. Under the elastic rebound of the compression spring 36, the sheet metal part can be clamped and positioned by the clamping plate 37. Close the top cover 4, put your hands inside the gloves 5, and you can easily see the inside of the processing box 1 through the transparent plate 6. Operate the sandblasting gun 81 to perform sandblasting on the surface of the sheet metal part. Turn the rotating disk 32, and under the action of the damping shaft connection of the upright 31, the rotating disk 32 can be moved with the movement of the hands, making it convenient to change the position of the sheet metal part for sandblasting by the sandblasting gun 81.

[0062] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
