Description

Technical Field

[0001] This utility model relates to the field of metal surface processing technology, and more specifically, to a metal surface sandblasting and polishing device. Background Technology

[0002] Sandblasting is a process that uses the impact of a high-speed abrasive stream to clean and roughen the surface of a substrate. Powered by compressed air, a high-speed jet propels abrasive materials (copper ore sand, quartz sand, corundum, iron sand, Hainan sand) at high speed onto the surface of the workpiece. This alters the appearance or shape of the workpiece surface. Due to the impact and cutting action of the abrasive, the workpiece surface achieves a certain degree of cleanliness and varying roughness, thus improving its mechanical properties. Currently, in the processing of metal sheets, sandblasting is required on both the upper and lower surfaces, while the side surfaces of the metal sheets do not require sandblasting.

[0003] Announcement No. CN218927459U proposes a sandblasting and grinding device for special alloy plates with a material recovery structure. This device can sandblast and grind the surface of the workpiece. However, after sandblasting the upper surface of the workpiece, it is necessary to manually flip it over before sandblasting the lower surface. Moreover, the sandblasting distance is not adjustable, so the sandblasting and grinding process of the workpiece needs to be optimized. Utility Model Content

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0029] like Figure 1 and Figure 2 As shown, a metal surface sandblasting and polishing device includes a sandblasting box 1, a servo motor 2, a first telescopic cylinder 3, a magnet 4, a grid 5, a limit block 51, a sealing door 6, a second telescopic cylinder 7, and sandblasting components.

[0030] The bottom of the sandblasting box 1 has a discharge port 101;

[0031] The servo motor 2 and the first telescopic cylinder 3 are both fixed on the top of the sandblasting box 1, and the motor shaft of the servo motor 2 passes through the sandblasting box 1 and is connected to a magnet 4 with a U-shaped main body that is snapped into the upper end face of the metal plate.

[0032] The grille 5 is connected to the first telescopic cylinder 3, and the two sides of the grille 5 are in contact with the side wall of the sandblasting box 1. The grille 5 is symmetrically fixed with limiting blocks 51 that are in contact with the bottom sides of the metal plate and are distributed opposite to the magnet 4.

[0033] The sealing door 6 is rotatably connected to the sandblasting box 1;

[0034] The second telescopic cylinder 7 is fixed on the side wall of the sandblasting box 1, and the second telescopic cylinder 7 is connected to a sandblasting assembly located inside the sandblasting box 1.

[0035] Specific implementation of the embodiments of this utility model, such as Figure 1 As shown, the sandblasting assembly includes a sandblasting device 8, a quick connector 9, a wear-resistant hose 10, a sandblasting box 11, and a nozzle 12 (specifically, the nozzle 12 is made of boron carbide material to extend its service life).

[0036] The sandblasting equipment 8 is fixed to the outer wall of the sandblasting box 1;

[0037] The wear-resistant hose 10 is connected to the output pipe of the sandblasting equipment 8 via the quick connector 9, and the input pipe of the sandblasting equipment 8 is connected to the sand box (the sand box is not shown in the figure);

[0038] The sandblasting box 11 is connected to one end of the wear-resistant hose 10, and the sandblasting box 11 is also connected to the second telescopic cylinder 7.

[0039] Several nozzles 12 are disposed on the sandblasting box 11 and are connected to the interior of the sandblasting box 11.

[0040] To facilitate external monitoring of the sandblasting progress by staff, further optimizations to the above-described embodiments are made, such as... Figure 2 As shown, a transparent and wear-resistant observation window 13 is provided on the sealed door 6.

[0041] To facilitate the collection of sand particles and other impurities that fall during the sandblasting and grinding process, the embodiments of this utility model are further refined, such as... Figure 1 As shown, the discharge port 101 is connected to the inside of the collection box 15 fixed on the sandblasting box 1 through the conveying pipe 14 to realize the centralized recovery of sand particles and impurities after sandblasting.

[0042] It should be noted that the servo motor 2, the first telescopic cylinder 3, the second telescopic cylinder 7, the sandblasting equipment 8, the horizontal slurry pump, and the non-contact material level sensor are all electrically connected to the controller, which is shown in the figure without a number.

[0043] The working process of this utility model is as follows:

[0044] First, open the sealing door 6 (the locking of the sealing door 6 and the sandblasting box 1 is common knowledge that should be known to those skilled in the art and will not be described in detail; a latch structure or other existing technical means can be used). Then, place a metal plate into the sandblasting box 1. During the placement process, keep the metal plate in a vertical position and have the upper end face of the metal plate engaged with the magnet 4 to achieve adsorption (the adsorption force can keep the metal plate stable when not sandblasting and when it is flipped later). Then, control the first telescopic cylinder 3 through the controller to drive the grille 5 to move up a pre-set distance to contact the lower end face of the metal plate (at the same time, the limiting block 51 also contacts the two sides of the bottom area of ​​the metal plate. The limiting block 51, together with the U-shaped magnet 4, can further ensure that the metal plate will not shift its position during the subsequent sandblasting process). Finally, close the sealing door 6. Since the gap of the grille 5 is large, the amount of residual sand particles can be ignored.

[0045] Then, the sandblasting equipment 8 is controlled by the controller to operate. The sand particles are then transported into the sandblasting box 11 and sprayed out through several nozzles 12. One side of the metal plate can then be effectively sandblasted and polished. After one side of the metal plate is sandblasted and polished, the sandblasting is stopped and the first telescopic cylinder 3 drives the grille 5 and the limiting block 51 away from the metal plate. Then, the controller controls the servo motor 2 to operate, which will cause the metal plate to rotate 180 degrees so that its other side faces the several nozzles 12. After the orientation of the metal plate is adjusted, the grille 5 and the limiting block 51 can then contact it again, and the other side can then be sandblasted and polished.

[0046] During the sandblasting process, the second telescopic cylinder 7 is controlled by the controller to adjust the distance between the nozzle 12 and the surface of the metal sheet. It should be noted that the sandblasting intensity is also automatically adjusted after the distance is adjusted (i.e., the sandblasting intensity corresponding to different distances is preset in the controller), which can improve the sandblasting effect. In addition, when the metal sheet changes position, the nozzle 12 is in a position away from the metal sheet and stops sandblasting, so as not to cause obstruction. Finally, the sealing door 6 is opened to complete the discharge of the metal sheet.

[0047] To extend the service life of the wear-resistant hose 10, the above-described embodiment is further optimized by using styrene-butadiene rubber to make the wear-resistant hose 10, and reserving a 20% margin in the length of the wear-resistant hose 10 to compensate for the deformation caused by the extension and contraction movement and prevent excessive stretching.

[0048] It should be noted that the sandblasting pressure in this application is ≤10MPa and the abrasive is conventional sand.

[0049] In order to automatically transfer the accumulated material in the collection box 15, in some embodiments, a horizontal slurry pump communicating with the inside of the collection box 15 is fixed on one side of the collection box 15. A non-contact level sensor is installed inside the collection box 15, which is not shown in the figure. The working principle of the horizontal slurry pump is prior art and will not be described. When the accumulated material in the collection box 15 reaches the preset material level height, the non-contact level sensor immediately sends a signal to the controller, and then the controller starts the horizontal slurry pump to transfer the material.

[0050] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
