Description

Technical Field

[0001] This utility model relates to the field of sand removal technology for the surface of molded valve bodies, and in particular to a sand removal device for the surface of the molded valve body of a buffer gate valve casting. Background Technology

[0002] During the molding and processing of cast valve bodies, sand particles remain on their surface. In the process of cleaning sand particles from the valve body surface, we have found that traditional cleaning methods have many defects. For example, manual cleaning is inefficient and the cleaning effect is not ideal for some complex valve bodies. Moreover, the quality of manual cleaning is difficult to control, and it is not suitable for cleaning some large valve bodies. Another example is shot blasting. The commonly used shot blasting equipment has some shortcomings and can usually only clean one side of the component. To achieve all-round cleaning, it is necessary to use a flipping device to flip the casting, which is not convenient to operate. It is difficult to use both of these methods on one machine at the same time, which brings great inconvenience to the sand removal work of valve bodies.

[0003] To address the aforementioned problems, this utility model provides improvements. Summary of the Invention

[0021] The following will refer to the appendix in the embodiments of this utility model. Figure 1-8 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0022] A sand-removing device for the forming surface of a buffer gate valve casting includes a frame 1, a housing 2 on the top of the frame 1, bases 3 fixedly connected to both sides of the bottom of the housing 2, the bottom of the bases 3 fixedly connected to the frame 1, an adjusting screw 5 rotatably mounted on the top of the bases 3, an adjusting support plate 4 threaded onto the surface of the adjusting screw 5, stepper motors 9 fixedly mounted on both sides of the top of the adjusting support plate 4 and the top of the bases 3, a guide rail 7 fixedly connected to one side of the bases 3, an adjusting frame 8 slidably mounted inside the guide rail 7, cleaning rollers 13 rotatably mounted on the inner sides of the adjusting frame 8 and the bases 3, the output end of the stepper motor 9 fixedly connected to the cleaning rollers 13, two positioning pins 6 inserted into one side of the bases 3, one end of the positioning pins 6 inserted into the adjusting frame 8, and an internal sand-removing device 25 fixedly mounted on the top of the housing 2.

[0023] This utility model adopts a dual-purpose structural design that can adjust the cleaning height according to the size of the valve body. It can flexibly and quickly adjust the working height of the brush roller according to the size of the valve body, meet the working adaptation and sand removal needs of valve bodies of different sizes, and can comprehensively clean the valve body, improve the cleaning effect and sand removal quality, and provide convenience for users.

[0024] The specific usage process is as follows: First, the cleaning rollers 13 installed on the two stepper motors 9 are height-adjustable. The cleaning roller 13 installed on the base 3 is fixed. It should be noted that in this solution, there is only one cleaning roller 13 installed on the base 3. The number of cleaning rollers 13 on the base 3 can be flexibly increased or decreased according to actual usage needs to meet more work requirements. This is existing technology. When cleaning sand particles from small workpieces, the cleaning roller 13 on the stepper motors 9 does not need adjustment. This cleaning roller 13 can work in conjunction with the cleaning roller 13 installed on the base 3. During operation, the workpiece is placed from the feed end of the equipment onto the conveyor device 14, which then transports the workpiece inwards. Then the workpiece enters the housing 2. At this time, the stepper motor 9 starts and drives the corresponding cleaning roller 13 to rotate. It should be noted that the surface of the cleaning roller 13 is equipped with brushes, and the bristles are in close contact with the workpiece surface, which can effectively clean the sand particles on the workpiece surface. It should be noted that the bristles can also be replaced with harder bristles, such as wire brushes or plastic bristles, depending on the actual needs. Then the workpiece is sent to the position directly below the internal sand-removing device 25 and pauses. At this time, the internal sand-removing device 25 will drive the other cleaning roller 13 installed at the output end to move down and extend into the workpiece. At the same time, the internal sand-removing device 25 can also drive the cleaning roller 13 to rotate. It should be noted that the internal... The sand-removing device 25 uses an electric push rod and a motor to simultaneously rotate and lower the cleaning roller 13. This is existing technology, which cleans the inner surface of the workpiece, completing the sand-removal work inside and outside the workpiece, improving the cleaning efficiency and providing convenience for users. It should be noted that, according to actual usage needs, the cleaning roller 13 can also be designed with an adjustable spacing structure. In the market, there are many mature technologies for this solution, and it has been put into actual use. Therefore, it will not be discussed in detail here. When cleaning large workpieces, the cleaning rollers 13 on both sides are adjusted upwards. The specific operation is as follows: the user rotates the adjusting screw 5, which is rotatably mounted on the base 3, and the base... 3 is fixed, while the adjusting plate 4 is threadedly connected to the adjusting screw 5. With the cooperation of the housing 2, the adjusting plate 4 is restricted and can move upwards with the rotation of the adjusting screw 5. Consequently, the stepper motor 9 and the cleaning roller 13 mounted on the adjusting plate 4 will move upwards together. Simultaneously, driven by the corresponding cleaning roller 13, the corresponding adjusting frame 8 will also move upwards. This adjusting frame 8 also slides within the guide rail 7. It should be noted that before operation, the positioning pins 6 must be completely pulled out of the corresponding positioning holes 11 and 10. After the cleaning roller 13 has moved to the appropriate height, stop rotating the adjusting screw 5, and then insert the positioning pins 6 back into the corresponding positioning holes 11 and 10.This fixes the adjusting frame 8 and the cleaning roller 13 at the current height, thus extending the working height of the multiple cleaning rollers 13. This allows for the cleaning of large workpieces, enabling the cleaning equipment to handle sand removal from both large and small workpieces. This reduces equipment purchase costs, improves workpiece cleaning efficiency, and meets the sand removal needs of workpieces of various sizes. Therefore, it adopts a dual-purpose structural design that adjusts the cleaning height according to the valve body size. This allows for flexible and quick adjustment of the brush roller's working height based on the valve body size, ensuring compatibility with different valve body sizes and meeting sand removal requirements. The valve body is cleaned of sand to improve the cleaning effect and quality, providing convenience for users. It should be noted that the adjusting plate 4 slides on the housing 2, thus the housing 2 provides limiting support for the movement of the adjusting plate 4, ensuring its stability. The belt on the adjusting plate 4 has a perforated design, allowing the cleaned sand to pass through and fall into the sand collection boxes 18, 19, and 20 below. These sand collection boxes 18, 19, and 20 are installed in the sand collection box 15 using a pull-out method. It is clear that sand droppers 18, 19, and 20 can be pulled out individually from the sand collection box 15, or they can be interlocked together and pulled out simultaneously. This facilitates sand cleaning and meets various user needs, providing convenience for users' work. Specifically, sand droppers 18, 19, and 20 are interlocked as follows: sand dropper 29 has symmetrically distributed clips 123 and 24, while sand droppers 18 and 20 have clips 23 and 24 respectively. Clips 23 and 24 on sand dropper 29 can respectively engage with sand dropper 18. The clips 1 (23) and 2 (24) on the sand drop box 3 (20) are interlocked. Specifically, clip 2 (24) is inserted from one side of clip 1 (23), and one side of clip 2 (24) is T-shaped. Similarly, the inner cavity of clip 1 (23) is also T-shaped. Sand drop boxes 1 (18), 2 (19), and 3 (20) should also be placed in the same manner to ensure that clips 1 (23) and 2 (24) can interlock. It should be noted that sand drop boxes 1 (18), 2 (19), and 3 (20) can be pulled out from the side with door 2 (17) or from the side with door 1 (16), providing convenience for the user.

[0025] The adjusting frame 8 has multiple positioning holes 10 on one side that are adapted to the positioning pin 6, the base 3 has multiple positioning holes 11 on one side that are adapted to the positioning pin 6, and the housing 2 has positioning holes 12 on both ends that are adapted to the positioning pin 6.

[0026] Specifically, the positioning holes 10, 11, and 12 are designed to accommodate the positioning pins 6. When installing the positioning pins 6, they are inserted from the outside of the housing 2, pass through the positioning hole 11, and finally enter the positioning hole 10, thereby positioning and fixing the adjusting frame 8, ensuring the stability of the cleaning roller 13, and providing convenience for the user.

[0027] The inner side of the frame 1 is detachably equipped with a conveying device 14, and the bottom of the frame 1 is provided with a sand drop box 15. One side of the sand drop box 15 is hinged with a box door 16, and three box doors 17 are hinged to one side of the sand drop box 15.

[0028] Specifically, the conveying device 14, sand drop box 15, box door 16, and box door 27 are configured as follows: the conveying device 14 is used to transport workpieces. After the workpiece is placed on the conveying device 14, it will be transported into the machine for sand removal, providing convenience for the user's work. The sand drop box 15 is used to install sand drop box 18, sand drop box 29, and sand drop box 30. Box door 16 is used to seal one side opening of the sand drop box 15, and the three box doors 27 are used to seal the other side opening of the sand drop box 15.

[0029] The sand drop box 15 is internally equipped with a sand drop box 18, a sand drop box 29, and a sand drop box 30. A handle 22 is fixedly installed on the side of the sand drop box 18 facing the door 16. A handle 21 is fixedly connected to the side of the sand drop box 18, the sand drop box 29, and the sand drop box 30 facing the door 27.

[0030] Specifically, the sand droppers 18, 19, and 20 are designed with three handles 21. The handles 21 are installed on the sand droppers 18, 19, and 20 respectively, allowing users to easily remove them individually from the sand box 15 for cleaning. The handle 22 is also installed on the sand dropper 18. When the sand droppers 18, 19, and 20 are connected end to end, they can be removed together from the sand box 15 for cleaning, providing convenience for users. The sand droppers 18, 19, and 20 are used to receive the falling sand.

[0031] The two ends of one side of the second sand box 19 are respectively fixedly installed with buckle 1 23 and buckle 2 24. The one side of the first sand box 18 and the third sand box 20 are respectively fixedly installed with buckle 1 23 and buckle 2 24, and buckle 2 24 is inserted into buckle 1 23.

[0032] Specifically, regarding the design of buckles 1 (23) and 24, when sand drop boxes 1 (18), 2 (19), and 3 (20) are used together, buckle 24 is inserted from one side of buckle 1 (23). One side of buckle 24 is T-shaped, and the inner cavity of buckle 1 (23) is also T-shaped. Sand drop boxes 1 (18), 2 (19), and 3 (20) must also be placed in the corresponding manner to ensure that buckles 1 (23) and 24 can be interlocked, thus connecting sand drop boxes 1 (18), 2 (19), and 3 (20) end to end. They can then be simultaneously pulled out from the direction of door 1 (16) to clean sand particles, providing convenience for users.
