[0021] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation of the present utility model. On the contrary, the embodiments of the present utility model include all changes, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0022] The sand washing device for the production of steel castings according to the embodiment of the present utility model will be described below with reference to the accompanying drawings.

[0023] As Figures 1 - 5 shown, the sand washing device for the production of steel castings according to the embodiment of the present utility model includes a processing box 1, two support bases 2, a box door 3, a self-locking part 4, and a sand washing mechanism 5. Among them, the two support bases 2 are relatively installed on the processing box 1, the box door 3 is rotatably arranged on the processing box 1, and the self-locking part 4 is arranged on the box door 3 and the processing box 1.

[0024] It should be noted that the self-locking part 4 is divided into two parts, one part is arranged on the box door 3, and the other part is arranged on the processing box 1.

[0025] It can be understood that the self-locking part 4 can automatically lock the closed box door 3. The self-locking part 4 refers to a hardware fitting that can automatically rebound or achieve the self-locking function through other mechanisms to ensure that the door or window can maintain a stable state after closing. It can be: a stainless steel bolt automatic rebound door and window buckle, an aluminum alloy cabinet door rebounder, a push-type bouncing door stopper, etc.

[0026] The sand washing mechanism 5 includes two moving grooves 51, four shrinking grooves 52, two sealing plates 53, a rotating motor 54, a threaded rod 55, an observation window 56, two fixing members 57 and a moving assembly 58. Among them, the two moving grooves 51 are oppositely opened on the processing box 1. The four shrinking grooves 52 are opened on the processing box 1, and the four shrinking grooves 52 are oppositely distributed on both sides of the corresponding moving groove 51. The two sealing plates 53 are slidably arranged between the moving groove 51 and the shrinking groove 52.

[0027] It should be noted that the length of the sealing plate 53 is slightly greater than the sum of the length of one moving groove 51 and one shrinking groove 52. Thus, even if the sealing plate 53 continuously moves in one direction, it can ensure that the sealing plate 53 is continuously inside the two shrinking grooves 52.

[0028] The rotating motor 54 is installed on one sealing plate 53, and the threaded rod 55 is threadedly connected to the other sealing plate 53. The observation window 56 is opened on the box door 3.

[0029] It should be noted that when processing a steel pipe shorter than the length of the observation window 56, in order to prevent the sand washing raw materials from splashing out from the inside of the observation window 56, a hanging curtain can be installed above the observation window 56 to achieve the purpose of blocking the sand washing raw materials. Secondly, one-third of the processing diameter of the steel pipe should not be less than the width of the observation window 56.

[0030] The two fixing members 57 are respectively connected to the rotating shaft of the rotating motor 54 and one end of the threaded rod 55, and the two fixing members 57 are located between the rotating motor 54 and the threaded rod 55.

[0031] It should be noted that the output end of the rotating motor 54 is fixedly connected to the fixing member 57. The purpose is to drive the steel pipe to rotate synchronously by using the rotating motor 54 and the fixedly connected fixing member 57. One end of the threaded rod 55 is rotatably connected to the other fixing member 57. The purpose is to prevent the other fixing member 57 from driving the threaded rod 55 to rotate.

[0032] The moving assembly 58 is arranged on the processing box 1.

[0033] Specifically, during the actual operation, the relevant personnel place the steel pipes to be sand-washed inside the sand-washing equipment and are unable to view the sand-washing situation. Based on this, by setting up the sand-washing mechanism 5, when sand-washing the steel pipes, first release the restriction of the self-locking member 4 on the box door 3, then open the box door 3. After the box door 3 is opened, place the steel pipe between the two fixing members 57, then use the two fixing members 57 to fix the steel pipe. After fixing, close the box door 3, and use the self-locking member 4 to position the closed box door 3. Then, move the rotating motor 54 and the threaded rod 55 towards the observation window 56, so that the rotating motor 54 and the threaded rod 55 move the steel pipe through the two fixing members 57, making the steel pipe contact the observation window 56. Then, control the output end of the rotating motor 54 to rotate, thereby driving the steel pipe connected to the fixing member 57 to rotate, and then sand-washing can be carried out. During sand-washing, the sand-washing situation can be observed through the observation window 56.

[0034] By setting up the observation window 56, when sand-washing the steel pipe, make the steel pipe fit with the observation window 56. Then, during the sand-washing process, the sand-washing situation of the steel pipe can be viewed. Furthermore, when observing insufficient sand-washing parts, the position of the sand-blasting head 587 can be adjusted in time to continuously sand-wash the insufficiently sand-washed parts, so as to improve the quality of sand-washing the steel pipes.

[0035] In an embodiment of the present utility model, as Figure 5 shown, two positioning members are provided on the processing box 1, and the two positioning members are respectively located on one side of the corresponding sealing plate 53.

[0036] It should be noted that after moving the rotating motor 54 and the threaded rod 55, in order to ensure the stability after movement, positioning needs to be carried out using the positioning members. The positioning members can adopt a clamping structure or a bolt extrusion method.

[0037] In an embodiment of the present utility model, as Figure 3 shown, a rotating disk is provided at the other end of the threaded rod 55.

[0038] It can be understood that the rotating disk at the other end of the threaded rod 55 is convenient for rotating the threaded rod 55.

[0039] In an embodiment of the present utility model, as Figure 3 and Figure 4 shown, the moving component 58 includes two support plates 581, a driving motor 582, a ball screw 583, a moving block 584, a moving plate 585, a moving groove 586, and a sand-blasting head 587. Among them, the two support plates 581 are relatively installed on the processing box 1. The driving motor 582 is installed on the support plate 581, and one end of the ball screw 583 is fixed on the rotating shaft of the driving motor 582.

[0040] It should be noted that the moving plate 585 is used to seal the moving groove 586, so that during use, the raw materials ejected by the sandblasting head 587 will not flow out from the inside of the moving groove 586.

[0041] The moving groove 586 is formed in the processing box 1. The moving block 584 is slidably arranged inside the moving groove 586, and the moving block 584 is threadedly connected to the ball screw 583. The moving plate 585 is mounted on the moving block 584, and the sandblasting head 587 is mounted on the moving plate 585.

[0042] It can be understood that a component for continuously supplying raw materials to the sandblasting head 587 is connected to the sandblasting head 587 to ensure that the sandblasting head 587 can sand-wash the steel pipe, and the pipeline for supplying materials to the sandblasting head 587 is a flexible hose, and the flexible hose will not affect the movement of the sandblasting head 587.

[0043] In an embodiment of the present utility model, as Figure 4 shown, the length of the moving plate 585 is twice the length of the moving groove 586.

[0044] Specifically, during use, while the above-mentioned steel pipe is rotating, the moving assembly 58 operates, the output end of the driving motor 582 drives the ball screw 583 to rotate, and under the action of the rotating ball screw 583, the moving block 584 can be driven to move, and then the moving block 584 drives the moving plate 585 and the sandblasting head 587 to move, so that the rotating steel pipe can be comprehensively sand-washed.

[0045] In summary, for the sand-washing device for cast steel parts in the embodiment of the present utility model, by providing an observation window, when sand-washing the steel pipe, the steel pipe is made to fit the observation window, and then during the sand-washing process, the sand-washing condition of the steel pipe can be checked. Furthermore, when observing insufficient sand-washing parts, the position of the sandblasting head can be adjusted in time to continuously sand-wash the insufficiently sand-washed parts, so as to improve the quality of sand-washing the steel pipe.
