Description

Technical Field

[0002] Surface treatment is an essential step in the casting production process. After casting, the surface of the casting must be treated. Shot blasting removes the coating layer on the surface of the casting, exposing the casting. Currently, after castings are removed from the casting box, they are transported to a cooling area for cooling before being transferred to the shot blasting process. This results in low production efficiency, large floor space requirements, and waste of manpower and resources. Summary of the Invention

[0040] The conveying structure includes a guide rail unit 1 and a catenary 2. The guide rail unit 1 includes a first loading guide rail 4 in the first loading area 3, a second loading guide rail 6 in the second loading area 5, a first cooling guide rail 8 and a second cooling guide rail 9 in the cooling area 7, a first cleaning guide rail 11 and a second cleaning guide rail 12 in the shot blasting cleaning area 10, and a lowering guide rail 14 in the lowering area 13, which are sequentially arranged. The end of the first loading guide rail 4 is connected to the starting end of the first cooling guide rail 8, and the end of the second loading guide rail 6 is connected to the starting end of the second cooling guide rail 9; the end of the first cooling guide rail 8 is connected to the middle of the second cooling guide rail 9, and the ends of the second cooling guide rail 9 are respectively connected to the starting ends of the first cleaning guide rail 11 and the second cleaning guide rail 12, and the ends of the first cleaning guide rail 11 and the second cleaning guide rail 12 are connected to the starting end of the lower piece guide rail 14, and the ends of the lower piece guide rail 14 are respectively connected to the starting ends of the first loading guide rail 4 and the second loading guide rail 6. In this way, the first loading guide rail 4, the first cooling guide rail 8, the first cleaning guide rail 11 and the lower piece guide rail 14 constitute a first guide rail, and the second loading guide rail 6, the second cooling guide rail 9, the second cleaning guide rail 12 and the lower piece guide rail 14 constitute a second guide rail, which can clean large castings and small castings as needed to improve work efficiency. The first loading rail 4, the second loading rail 6, the first cooling rail 8, the second cooling rail 9, the first cleaning rail 11, the second cleaning rail 12, and the unloading rail 14 are all I-shaped rails. The catenary 2 is provided on the guide rail unit 1 and is slidably connected to the guide rail unit 1. The I-shaped guide rail design provides a better sliding connection with the catenary 2, and the catenary 2 reciprocates along the guide rail unit 1.

[0041] The suspension mechanism is provided on the conveying mechanism, and the suspension mechanism includes a hanging plate 15. The hanging plate 15 includes a hanging rod 16 and a hook 17, a rotating disk 18, a hanging plate body 19 and a fixed block 20 arranged on the hanging rod 16 from top to bottom. The hook 17 is provided on the top of the hanging rod 16 and is suspended on the catenary 2. The rotating disk 18 is rotatably connected to the hanging rod 16, and the hanging rod 16 rotates relative to the rotating disk 18. The hanging plate body 19 is fixed on the hanging rod 16. The hanging plate body 19 is a three-layer hexagonal frame 21 structure inside and outside.

Support arms 23 arranged in a circular array along the hanging rod 16 are provided between adjacent outer hexagonal frames 21. The support arms 23 are used to place castings. After the castings are filled, the hanging plate body 19 remains balanced. The non-drop casting cooling and cleaning system also includes a retrieval robot 32 for placing castings onto the support arm 23. The fixing block 20 is located at the bottom of the suspension rod 16 and is used to cooperate with the fixing mechanism to maintain the stability of the hanging plate 15. By using a conveying structure and a suspension structure, castings suspended on the hanging plate 15 do not need to drop to the ground for cooling and shot blasting, thus occupying a small area and reducing transportation time and labor costs.

[0042] The fixing mechanism is located below the suspension mechanism and below the guide rail unit 1 in the first upper component area 3, the second upper component area 5, and the lower component area 13. The fixing mechanism includes a cylinder 24, a housing 25, and a clamping claw 26. The cylinder 24 is fixedly mounted on the left side wall of the housing 25.

A clamping member 29 is provided on the side wall of the other end of the clamping claw 26, and a set of rotating rollers 30 are provided on the clamping member 29. The control structure is electrically connected to the cylinder 24. After the protruding end of the cylinder 24 is extended, the rotating assembly 28 drives the clamping claw 26 to close, and the two sets of rotating rollers 30 clamp the fixed block 20. After the protruding end of the cylinder 24 is retracted, the rotating assembly 28 drives the clamping claw to open, and the two sets of rotating rollers 30 release the fixed block 20. When the clamping claw 26 is closed, the two sets of rotating rollers 30 on the two clamping claws 26 are used to clamp the fixed block 20. When the clamping claw 26 is closed, the gap size between the two sets of rotating rollers 30 on the two clamping claws 26 is equal to the diameter size of the fixed block 20, which facilitates the fixation of the fixed block 20. By selecting a fixed structure, the hanging plate 15 is easy to fix, saving the time of manual fixation.

[0043] The cleaning mechanism is arranged below the suspension mechanism, and the cleaning mechanism is arranged below the guide rail unit 1 of the shot blasting cleaning area 10. The cleaning mechanism includes a through-type shot blasting machine 31 arranged below the first cleaning guide rail 11 and the second cleaning guide rail 12.

[0050] When the casting is a large casting, the catenary 2 drives the hanging plate 15 to move to the second loading area 5 on the second loading guide rail 6;

[0051] 3) Place and stabilize the casting:

[0052] When the catenary 2 drives the hanging tray 15 to move to the corresponding loading area, the cylinder 24 extends and the clamping claws 26 close to clamp the fixing block 20 to prevent it from shaking. The casting is placed on the support arm 23 of the hanging tray 15 by the retrieval manipulator 32, and the hanging tray body 19 is rotated to fill the castings in turn to keep the hanging tray body 19 stable.

[0053] 4) Cooling and cleaning castings:
