Description

Technical Field

[0001] This utility model relates to the field of metal casting technology, specifically to a shot peening device for metal casting. Background Technology

[0002] Shot peening is a surface strengthening process that uses shot to bombard the surface of a workpiece, implanting residual compressive stress, thereby improving the fatigue strength and wear resistance of the workpiece. The main functions of shot peening in metal casting include improving the fatigue strength of parts, extending service life, enhancing wear resistance and corrosion resistance, etc., and it is widely used in the surface strengthening of various metal parts.

[0003] Application No. 202023064350.4 discloses a shot peening strengthening device for metal surface treatment. By setting a workpiece box, the object to be processed is first placed in the workpiece box, and then the shot peening device is started. The workpiece is shot peened through the abrasive nozzle. During the shot peening process, the drive motor is started, so that the screw rotates stably between two connecting blocks. Since a threaded sleeve adapted to it is provided in the moving block, and the rotation of the moving sleeve is restricted by the cooperation of the moving sleeve and the fixed rod, the rotation of the screw pushes the moving sleeve to move left and right, which drives the meshing rod to slide left and right. Through meshing, the rotating gear rotates around the rotating shaft, which drives the shot peening device to rotate, thereby changing the angle of the abrasive nozzle.

[0004] The workpiece box mentioned above is only for storing workpieces and cannot be adjusted according to workpieces of different sizes. The workpieces are prone to displacement during shot peening, and the shot particles, dust and harmful gases generated during shot peening are directly discharged, which can easily cause waste and endanger the health of workers.

A fixed part is installed on one side of the convex groove 5. A first motor 9 is connected to a bidirectional lead screw 8 at its output end. A second motor 10 is fixedly installed on the outer wall of the worktable 1. The output end of the second motor 10 is connected to a clamp 4, driving the clamp 4 to rotate. The workpiece is fixed by two positioning plates 7, which facilitates the rotation of the workpiece and shot peening the back of the workpiece, improving processing efficiency. A support frame 17 is rotatably connected to the top of the operating cavity 3. A convex limiting groove 18 is opened inside the support frame 17. A convex limiting block 19 is slidably connected inside the convex limiting groove 18. A first electric push rod 20 is connected to the bottom of the convex limiting block 19. An adjuster 21 is connected to the output end of the first electric push rod 20. A shot peening device 22 is rotatably connected to one side of the adjuster 21. A shot peening material is installed at the bottom of the shot peening device 22. The nozzle 23 and the convex limiting groove 18 are equipped with a second electric push rod 24. The output end of the second electric push rod 24 is connected to the convex limiting block 19, pushing the convex limiting block 19 to move. Through the support of the convex limiting block 19 on the first electric push rod 20, the adjuster 21, and the shot peening device 22, the shot peening device 22 moves accordingly. In conjunction with the extension of the first electric push rod 20, the position and height of the shot peening device 22 can be easily adjusted to meet different processing requirements. The inside of the adjuster 21 is rotatably connected to a worm gear 27 and a worm 28, which mesh with each other. The worm gear 27 is connected to the shot peening device 22. A fourth motor 29 is installed on the outer wall of the adjuster 21. The output end of the fourth motor 29 is connected to the worm 28. Under the action of the worm gear 27, the fourth motor moves. The shot peening device 22 is driven by the worm gear 28. As the fourth motor 29 drives the worm gear 28 to rotate, the shot peening device 22 rotates accordingly, facilitating adjustment of the nozzle angle 23. A third motor 25 is installed on the top of the protective box 2. The output end of the third motor 25 is connected to the support frame 17, driving the support frame 17 to rotate and adjust its direction, which helps to further expand the movement and spraying range of the nozzle 23.

Through the threaded connection between the bidirectional lead screw 8 and the two convex sliders 6, and the connection between the two convex sliders 6 and the two positioning plates 7, the two positioning plates 7 are moved accordingly, clamping and fixing the workpiece. The shot nozzle 23 sprays the shot particles from the shot peening device 22 onto the surface of the workpiece. At the same time, the second electric push rod 24 drives the convex limiting block 19 to move, causing the first electric push rod 20 below the convex limiting block 19 and the adjuster to move. 21 drives the shot peening device 22 and the nozzle 23 to move and shot peening the remaining parts of the workpiece. Similarly, the second motor 10 drives the clamp 4 to rotate, which can drive the workpiece to flip and shot peening the back of the workpiece. The fan 26 is started to dissipate heat. The dust and gas generated during shot peening enter the water tank 12 through the exhaust pipe 11. After being washed by the water in the water tank 12, the dust and water droplets fully contact and settle down. The gas is discharged after being filtered by the filter element in the air guide pipe 13 on the water tank 12. At the same time, multiple sieve frames 16 in the operating chamber 3 sequentially sieve and collect the shot.
