Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, specifically to a shot blasting cleaning device for casting surfaces. Background Technology

[0002] Tracked shot blasting machines use high-strength, wear-resistant rubber or manganese steel tracks to load workpieces. They utilize a high-speed rotating impeller to propel shot onto the workpiece within the chamber, achieving the cleaning purpose. They are suitable for cleaning sand, removing rust, removing oxide scale, and surface strengthening of small castings, forgings, stampings, gears, springs, etc., and are particularly suitable for cleaning and strengthening parts that are not susceptible to impact.

[0003] The track in a tracked shot blasting machine is a key component, responsible for transporting workpieces and subjecting them to shot blasting. However, wear and breakage of the track can affect the normal operation of the equipment. The track needs to rotate continuously during use, making it a vulnerable part for tracked shot blasting machines. Therefore, it requires regular inspection and maintenance, and track replacement is a cumbersome and labor-intensive process. To address this, we propose a shot blasting cleaning device for casting surfaces. Utility Model Content

[0004] This utility model provides a shot blasting cleaning device for casting surfaces. The material container used to load the parts has a high structural strength and the advantage of not deforming after long-term use, thus solving the problems mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows: A shot blasting cleaning device for casting surfaces includes a housing, which is mounted on a frame. An inlet and outlet are provided on one side of the housing. A shot blasting port is provided on the housing above the inlet and outlet, and a shot blaster is provided at the edge of the shot blasting port. A material container is provided inside the housing and is rotatably mounted within a ring frame. Support shafts are symmetrically arranged on both sides of the ring frame, and the two support shafts are rotatably mounted on the housing. The end of the material container furthest from its opening is coaxially connected to a drive motor. The drive motor is mounted on a U-shaped frame, and both ends of the U-shaped frame are connected to the ring frame. An adjustment motor connected to the support shafts is provided on the outer side of the housing. Driven by the adjustment motor, the top opening of the material container is aligned with the shot blaster. Several shot drop holes are provided on the bottom surface of the material container. This utility model also includes a circulating feeding device for supplying material to the shot blaster.

[0006] Preferably, a sealing door is provided on the inlet / outlet side.

[0007] Preferably, the circulating feeding device includes an elevator located on one side of the machine casing, and the inlet at the bottom of the elevator is connected to the bottom of the machine casing via a pipe.

[0008] The outlet at the top of the elevator is connected to the collection box via a pipe. The collection box is located at the top of the machine casing, and the bottom of the collection box is connected to the inlet of the shot blasting machine via a pipe.

[0009] Preferably, an angle sensor is provided at the end of the support shaft away from the adjusting motor. The angle sensor is connected to the controller, which is also connected to the drive motor, shot blaster, elevator and adjusting motor respectively.

[0010] Preferably, the controller is located inside a control cabinet.

[0011] Preferably, the bottom of the casing is a conical structure, and the pipe connected to the inlet at the bottom of the elevator is installed at the bottom of the conical structure.

[0012] Preferably, the side of the hoist is connected to the casing by a fixing frame.

[0013] Preferably, a discharge valve is provided on the bottom side of the elevator.

[0014] Preferably, the bottom of the inlet and outlet is provided with a material leveling plate on the side near the inner cavity of the machine casing.

Detailed Implementation

[0024] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. 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.

[0025] Reference Figures 1 to 6 This utility model provides a technical solution: a shot blasting cleaning device for casting surface, including a housing 1, the housing 1 is installed on a frame 5, the frame 5 is supported on the ground, an inlet and outlet 13 is provided on one side of the housing 1, and a sealing door 11 is rotatably provided on one side of the inlet and outlet 13. The sealing door 11 is closed during shot blasting, and opened when taking out, discharging or adding shot. The sealing door 11 is fixed to the inlet and outlet 13 by a lock.

[0026] like Figure 1 As shown, a shot blasting port 14 is provided on the housing 1 above the inlet / outlet 13. A shot blaster 15 is located at the edge of the shot blasting port 14, and the shot blasting direction of the shot blaster 15 is along the shot blasting port 14 into the housing 1. During use, the shot blaster 15 is fed by a circulating feeding device, such as... Figure 1 As shown, the circulating feeding device includes an elevator 3 located on one side of the housing 1. The elevator 3 is a screw elevator. The inlet at the bottom of the elevator 3 is connected to the bottom of the housing 1 through a pipe. The pipe is inclined upward so that the shot falling into the housing 1 can automatically flow into the bottom of the elevator 3 through the pipe. In order to better concentrate the shot towards the bottom of the housing 1, the bottom of the housing 1 is specially designed as a conical structure. The pipe connected to the inlet at the bottom of the elevator 3 is installed at the bottom of the conical structure, so that the shot can automatically gather towards the bottom of the housing 1.

[0027] The elevator 3 gradually lifts the shot upwards and it falls into the collection box 2. The outlet at the top of the elevator 3 is connected to the collection box 2 via a pipe. This pipe is angled downwards to allow the shot to fall automatically along the pipe. Figure 1As shown, the collection box 2 is set on the top of the machine casing 1, and the bottom of the collection box 2 is connected to the inlet of the shot blaster 15 through a pipe, so that the shot continuously enters the shot blaster 15 and is blasted out.

[0028] During use, shot is added into the housing 1 through inlet / outlet 13 until it fills two-thirds of the bottom volume of the housing 1. The shot then circulates automatically under the drive of the elevator 3. However, even the most wear-resistant shot needs to be replaced. This application also facilitates shot replacement, such as... Figure 1 As shown, a discharge valve 19 is provided on the bottom side of the elevator 3. When the shot needs to be replaced, simply open the discharge valve 19. At this time, the channel for the shot to rise inside the elevator 3 is cut off, and the shot will be continuously discharged along the discharge valve 19. When the shot in the housing 1 is emptied, it proves that the old shot has been emptied, and new shot can be added to continue to be used.

[0029] Furthermore, during the shot blasting process, the shot is sprayed into the container 12, and the parts are also stored inside the container 12, such as... Figure 1 As shown, a material container 12 is provided inside the housing 1. The material container 12 is rotatably mounted inside the annular frame 10. Support shafts 18 are symmetrically arranged on both sides of the annular frame 10. The two support shafts 18 are coaxially arranged and rotatably mounted on the housing 1. The end of the material container 12 away from its opening is coaxially connected to the drive motor 8. The drive motor 8 is mounted on a U-shaped frame 7. Both ends of the U-shaped frame 7 are connected to the annular frame 10. When the drive motor 8 rotates, it can drive the material container 12 to rotate at a certain speed, thereby causing the parts inside to tumble. Several shot drop holes 16 are provided on the bottom surface of the material container 12. The shot drop holes 16 are provided to allow the shot to fall quickly.

[0030] like Figure 4 As shown, an adjustment motor 17 connected to the support shaft 18 is provided on the outer side of the housing 1. It should be noted that the material container 12 in this application has at least three states.

[0031] The first type is shot blasting, such as... Figure 1 As shown, driven by the adjusting motor 17, the top opening of the material container 12 is aligned with the shot blaster 15. This means the direction of the shot blasting is directed towards the parts inside the material container 12. The specific blasting direction is as follows: Figure 1 The middle arrow points to;

[0032] The second type is the state of the parts being tilted, such as... Figure 2As shown, the regulating motor 17 drives the material cylinder 12 to rotate, causing the material cylinder 12 to tilt downwards, thereby allowing the parts to tilt out. In order to prevent the parts from falling into the machine housing 1, a material leveling plate 9 is provided at the bottom of the inlet and outlet 13 on the side close to the inner cavity of the machine housing 1. When discharging, the regulating motor 17 drives the opening edge of the material cylinder 12 to be placed on the material leveling plate 9, so that the tilted parts fall down along the material leveling plate 9.

[0033] The third type is the state of adding parts, such as Figure 3 As shown, adjust the motor 17 to drive the material container 12 to rotate, so that the material container 12 is aligned with the inlet and outlet 13, and at this time the material container 12 is slightly tilted upward. Then add the parts into the material container 12.

[0034] All three states require precise angle control. Therefore, an angle sensor (not shown in the figure) is installed at the end of the support shaft 18, which is away from the adjusting motor 17. The angle sensor is mounted on the housing 1 via a sensor bracket. Each of the three states corresponds to a set angle. In use, the adjusting motor 17 drives the support shaft 18 to rotate to the preset angle. The angle sensor is connected to the controller, which continuously monitors the rotation angle of the material container 12 and feeds it back to the controller. The controller is either a PLC logic controller or a main unit, and it is located inside the control cabinet 6. Figure 1 As shown, the control cabinet 6 is mounted on the frame 5. The controller is then connected to the drive motor 8, shot blaster 15, elevator 3, and regulating motor 17.

[0035] Furthermore, to make the hoist 3 more stable, the side of the hoist 3 is connected to the casing 1 by a fixing frame 4.

[0036] Based on the above embodiments, further optimization can be made. In actual use, the housing 1 is also connected to the induced draft fan through a pipe, and the induced draft fan is connected to the dust collector through a pipe, so that the dust generated by shot blasting is drawn out by the induced draft fan and filtered by the dust collector.

[0037] Based on the above embodiments, further optimization can be achieved by fixing the two ends of the equalizing plate 9 to the inner wall of the housing 1, and by making the equalizing plate 9 a porous structure, so that the shot remaining in the parts can fall into the housing 1 along the equalizing plate 9.

[0038] Based on the above embodiments, it should be further explained that the regulating motor 17 is a servo brake motor, which not only has high speed but also can be locked at any time.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
