Description

Technical Field

[0002] In the casting process, the sand removal process is a crucial step, aiming to separate the casting from the molding sand. Traditional sand removal methods typically employ single-function equipment, such as relying solely on vibration or manual hammering to remove the molding sand. These methods often fail to effectively remove some firmly bonded molding sand, resulting in incomplete casting cleaning and impacting subsequent processing. Manual hammering is not only inefficient but also extremely physically demanding for workers and poses safety hazards. Furthermore, for large workpieces with complex internal structures, the shaken-off sand can easily remain inside, making thorough cleaning difficult. Therefore, developing a multi-functional, high-efficiency sand removal device is of significant practical importance. Utility Model Content

[0017] like Figure 1-3 As shown, the three-in-one sand removal machine includes a fixed frame 1, a rotating frame 2, a workpiece fixing table 3, a hammering mechanism, a vibration mechanism, and a tilting mechanism. The rotating frame 2 is rotatably mounted on the fixed frame 1. The tilting mechanism includes a tilting motor 4, which drives the rotating frame 2 to rotate via a horizontally set rotating shaft. The workpiece fixing table 3 is fixedly connected to the rotating frame 2 and has several workpiece clamping mechanisms 6 installed on it. The vibration mechanism includes several vibration motors 7, which are respectively mounted on the workpiece fixing table 3. The hammering mechanism includes several air hammers 8, which are respectively mounted on rotating arms 9. One end of each rotating arm 9 is rotatably connected to the fixed frame 1 and is driven to rotate by a rotation drive mechanism. When a workpiece is placed on the workpiece fixing table 3, the workpiece clamping mechanism 6 clamps it. The vibration motors 7 cause the workpiece fixing table 3 to vibrate, causing the workpiece to vibrate continuously, thus shaking off the molding sand from the surface and interior of the workpiece. The rotating arm 9 rotates, causing the air hammer 8 to move above the workpiece. The air hammer 8 is activated and moves vertically to a specific position on the workpiece, shaking off the firmly adhered molding sand. The flipping motor 4 drives the rotating frame 2 to rotate, causing the workpiece to flip at a certain angle, facilitating the removal of molding sand from the workpiece.

[0018] Furthermore, the workpiece clamping mechanism 6 is located at both ends of the workpiece fixing platform 3. The workpiece clamping mechanism 6 includes an outer sleeve 10, a telescopic shaft 11, a pressure arm, and a clamping cylinder 12. The outer sleeve 10 is fixedly connected to the workpiece fixing platform 3. The middle part of the telescopic shaft 11 is located inside the outer sleeve 10. The upper end of the telescopic shaft 11 is connected to the pressure arm, and the lower end of the telescopic shaft 11 is connected to a cover plate 13. An air bladder 14 is connected to the cover plate 13 and is connected to the outer sleeve 10. The upper end of the telescopic shaft 11 is connected to the output shaft of the clamping cylinder 12, and the clamping cylinder 12 is fixed on the rotating frame 2. The workpiece clamping mechanism 6 is a workpiece clamping device with a buffering function disclosed by the applicant in the utility model patent application number 2023216038338 (publication number CN220216705U), which can protect the clamping cylinder 12 during continuous vibration of the workpiece while ensuring the clamping effect on the workpiece.

[0019] Furthermore, spring steel plates 15 are respectively provided on both sides of the workpiece fixing table 3, and the rotating frame 2 is fixedly connected to both ends of the spring steel plates 15. The workpiece fixing table 3 is fixedly connected to the middle of the spring steel plates 15. The vibration motor 7 is located below the workpiece fixing table 3 and fixed on the workpiece fixing table 3. The spring steel plates 15 are elastic, so that the workpiece fixing table 3 can vibrate when the vibration motor 7 is working.

[0020] Furthermore, a horizontal shaft 16 is rotatably connected to one side of the fixed frame 1. One end of the rotating arm 9 has a through hole 17 for the horizontal shaft 16 to pass through. The rotating arm 9 is fixed to the horizontal shaft 16 by a clamping bolt 25. A movable hole 18 is provided in the middle of the rotating arm 9. The rotation drive mechanism includes a rotating cylinder 19, which is hinged to the fixed frame 1. The output shaft of the rotating cylinder 19 is hinged to a linkage shaft 20, which passes through the movable hole 18. The rotating cylinder 19 pushes the rotating arm 9 to rotate around the horizontal shaft 16, thereby moving the air hammer 8 above the workpiece to hammer it. When the workpiece needs to be flipped and vibrated, the air hammer 8 is moved away from above the workpiece. Loosening the clamping bolt 25 allows the rotating arm 9 to move axially along the horizontal shaft 16, thereby adjusting the vertical position of the air hammer 8 according to the workpiece model.

[0021] Furthermore, there are two rotating cylinders 19, located on opposite sides of the linkage shaft 20. The two rotating cylinders 19 operate synchronously, controlling the movement of the linkage shaft 20, which in turn controls the rotation of the rotating arm 9, driving the air hammer 8 to move.

[0022] Furthermore, a waste collection hopper 21 is installed on the fixed frame 1, and the rotating frame 2 is located above the waste collection hopper 21. The waste collection hopper 21 collects the shaken-down sand for unified recycling and processing.

[0023] Furthermore, an isolation chamber 22 is installed on the fixed frame 1. A workpiece inlet / outlet 23 is provided on one side of the isolation chamber 22, and a movable door is provided at the workpiece inlet / outlet 23. Workpieces enter and exit the isolation chamber 22 through the workpiece inlet / outlet 23. During the workpiece sand removal operation, the movable door covers the workpiece inlet / outlet 23.
