Description

Technical Field

[0001] This invention relates to a shot blasting device, and more particularly to a shot blasting device for processing exhaust manifolds. Background Technology

[0002] The exhaust manifold is connected to the engine cylinder block, collecting the exhaust gas from each cylinder and directing it into the main exhaust pipe. It is a branching pipe system. Its main requirements are to minimize exhaust resistance and prevent interference between cylinders. The exhaust manifold separates the exhaust gas from each cylinder as much as possible, with one branch per cylinder or one branch for two cylinders. Each branch is made as long as possible and independently shaped to reduce mutual influence between gases in different pipes. Exhaust manifolds are generally cast and then further processed. After processing, the exhaust manifold needs to be painted for rust prevention. Before painting, the exhaust manifold needs to be shot-blasted. This ensures a more stable bond between the paint and the outer surface of the exhaust manifold, and more importantly, removes surface rust and stains. Otherwise, the paint will cover the rust, resulting in air pockets between the paint and the exhaust manifold surface, making the exhaust manifold prone to corrosion during subsequent use.

[0003] Shot blasting of exhaust manifolds typically uses a hook-type shot blasting machine. The method involves suspending the exhaust manifold on a hook, which then moves into the blasting chamber. The shot blasting device sprays shot into the chamber to blast the exhaust manifold. Simultaneously, the hook moves back and forth and rotates within the chamber, improving the quality and efficiency of the shot blasting process. However, exhaust manifolds have complex shapes, with many narrow spaces on their outer surface, similar to dead angles. Although the hook moves back and forth and rotates, the processing time for exhaust manifolds is longer compared to other irregularly shaped parts. Furthermore, the processing quality of the outer surface of the exhaust manifold, especially in the dead angles, is poor, requiring separate treatment, which is time-consuming and labor-intensive. The specific reason is that when shot is blasted into the dead angles, most of the shot is reflected and splashed rather than directly sprayed, resulting in insufficient blasting force. Summary of the Invention

[0004] The purpose of this invention is to provide a shot blasting equipment for exhaust manifold processing, which has the advantages of comprehensive multi-angle and multi-directional spraying, and solves the problem of long processing time and low processing quality caused by insufficient spraying force in the dead corners of the outer surface of the exhaust manifold in the prior art.

[0015] I. This invention, by setting up a housing, shot peening device, drive device, slide rail assembly, hook assembly, and centrifugal drive device, allows the corresponding outer and inner hooks to suspend the same exhaust manifold during use. Then, the housing door is opened, and the drive device drives the hook assembly to slide back and forth along the slide rail assembly. Simultaneously, the slide rail assembly drives the hook to rotate. The centrifugal drive device, based on the rotation of the hook assembly, generates centrifugal force to drive the inner hook of the hook assembly to move up and down reciprocally, cooperating with the outer hook at a constant height, thereby changing the suspension angle of the exhaust manifold. The hook assembly enters the housing along the slide rail, and then the drive device drives the hook assembly to move back and forth within the housing. Simultaneously, the shot peening device sprays steel shot into the housing to perform shot peening on the exhaust manifold. As the exhaust manifold rotates with the hook assembly, its suspension posture also periodically oscillates, allowing the steel shot to more comprehensively peening the exhaust manifold. Due to the periodic change in the suspension posture of the exhaust manifold, the shot peening device can more easily directly spray into the dead corners of the exhaust manifold's outer surface, improving processing quality and efficiency.

[0016] II. This invention, through the arrangement of a boom, follower plate, ratchet, movable plate, sleeve, centrifugal rod, and hinge rod, achieves the following: During use, the boom rotates, driving the movable plate via the ratchet. The movable plate then drives the centrifugal rod, which in turn drives the centrifugal ball (simultaneously, the centrifugal rod drives the follower plate to rotate with the boom via the hinge rod). The centrifugal ball's rotation generates centrifugal force, causing it to move upwards. This upward movement of the centrifugal ball causes the top of the centrifugal rod to move downwards, which in turn drives the movable plate downwards. The movable plate then drives the sleeve downwards, which in turn drives each inner hook downwards, while the height of the outer hook remains unchanged. This alters the suspension posture of the exhaust manifold. The boom reciprocates, driving the sleeve to reciprocate. During this reciprocating rotation, the sleeve can only... In one direction of rotation, a ratchet drives the movable disc to rotate, while in the other direction, the sleeve does not drive the movable disc to rotate. Therefore, during the reciprocating rotation of the sleeve, when the sleeve drives the movable disc to rotate, the centrifugal ball generates centrifugal force, causing the sleeve to move downwards, thereby changing the suspension posture of the exhaust manifold. When the sleeve rotation cannot drive the movable disc to rotate, the centrifugal ball cannot generate centrifugal force and falls downwards under the action of gravity, causing the top of the centrifugal rod to push the movable disc upwards. The movable disc drives the sleeve upwards, and the sleeve drives the inner hook upwards, restoring the suspension posture of the exhaust manifold to its previous state. In this way, the suspension posture of the exhaust manifold changes back and forth, ultimately achieving the purpose of more effectively shot blasting the exhaust manifold.

[0019] Please see Figure 1-11 The present invention will now be described in detail with reference to the accompanying drawings and embodiments: The shot blasting equipment for exhaust manifold processing of the present invention includes a housing 1 and a shot blasting device 2. The shot blasting device 2 sprays steel shot into the housing 1. A drive device 3 and a slide rail assembly 4 are fixedly installed above the housing 1. A hook assembly 5 is slidably installed on the slide rail assembly 4. The hook assembly 5 includes an outer hook 6 and an inner hook 7. The corresponding outer hook 6 and inner hook 7 together suspend the same exhaust manifold 8. The drive device 3 drives the hook assembly 5 to slide back and forth along the slide rail assembly 4. At the same time, the slide rail assembly 4 drives the hook to rotate. A centrifugal drive device 15 is installed at the bottom of the hook assembly 5. The centrifugal drive device 15 generates centrifugal force based on the rotation of the hook assembly 5 to drive the inner hook 7 of the hook assembly 5 to move up and down back and forth, thereby changing the suspension angle of the exhaust manifold 8. Finally, the purpose of the exhaust manifold 8 rotating with the hook assembly 5 and the suspension angle changing periodically is achieved. The shot blasting device 2 sprays steel shot into the housing 1 to perform shot blasting processing on the exhaust manifold 8.

[0020] Because the suspension posture of the exhaust manifold 8 changes periodically, the shot peening device 2 can more easily spray directly onto the dead corners of the outer surface of the exhaust manifold 8, thereby improving processing quality and efficiency.

[0021] In use, the exhaust manifold 8 is hung on the hook assembly 5, so that the corresponding outer hook 6 and inner hook 7 suspend the same exhaust manifold 8. Then, the door of the housing 1 is opened, and the drive device 3 drives the hook assembly 5 to slide back and forth along the slide rail assembly 4. At the same time, the slide rail assembly 4 drives the hook to rotate. The centrifugal drive device 15 generates centrifugal force based on the rotation of the hook assembly 5, which drives the inner hook 7 of the hook assembly 5 to move up and down back and forth, thereby changing the suspension angle of the exhaust manifold 8. The hook assembly 5 enters the housing 1 along the slide rail 11, and then the drive device 3 drives the hook assembly 5 to move back and forth in the housing 1. At the same time, the shot blasting device 2 sprays steel shot into the housing 1 to perform shot blasting on the exhaust manifold 8. As the exhaust manifold 8 rotates with the hook assembly 5, its suspension posture also swings periodically, so that the steel shot can perform shot blasting on the exhaust manifold 8 more comprehensively.

[0022] In this embodiment, a gear 9 is fixedly installed at the top of the hook assembly 5. A lifting cylinder 10 is rotatably connected to the upper end face of the gear 9. The execution end of the drive device 3 drives the lifting cylinder 10 to move. The lifting cylinder 10 drives the hook assembly 5 to move through the gear 9. The slide rail assembly 4 includes two parallel slide rails 11. A rack 12 is fixedly installed on the inner side of one slide rail 11, and a groove 13 is opened on the inner side of the other slide rail 11. The hook assembly 5 is slidably connected to the corresponding slide rail 11 through the groove 13. The gear 9 meshes with the rack 12. When the drive device 3 drives the hook assembly 5 to move, the hook assembly 5 slides along the groove 13 of the corresponding slide rail 11. At the same time, the gear 9 rotates, and the rotation of the gear 9 drives the hook assembly 5 to rotate, so that when the hook assembly 5 slides along the slide rail assembly 4, the slide rail assembly 4 drives the hook assembly 5 to rotate.

[0023] In this embodiment, the hook assembly 5 includes a rod 14, the top end of which is fixedly mounted to a gear 9, and a centrifugal drive device 15 is provided at the bottom end of the rod 14. A sleeve 16 is fitted on the rod 14 located below the gear 9, and a guide block 17 is provided on the outer surface of the sleeve 16. The guide block 17 is located in the slide groove 13 and is slidably connected to the corresponding slide rail 11, so as to realize the purpose of the hook assembly 5 being slidably connected to the corresponding slide rail 11 through the slide groove 13.

[0024] In this embodiment, an inner rod 19 is fixedly installed on the outer surface of the sleeve 16, and an outer tube 20 is sleeved on the outer surface of the inner rod 19. The outer end of the outer tube 20 is fixedly installed with the guide block 17. A compensation spring 21 is installed inside the sleeve 16. One end of the compensation spring 21 is fixedly installed with the inner bottom wall of the outer tube 20, and the other end of the compensation spring 21 is fixedly installed with the inner rod 19. The compensation spring 21 pushes the sleeve 16 and the lifting rod 14 to move to the opposite side, so that the gear 9 and the rack 12 mesh more stably.

[0025] In this embodiment, a plurality of radial rods 22 are fixedly arranged radially on the outer surface of the boom 14, and an outer hook 6 is fixedly arranged vertically at the outer end of each radial rod 22; a sleeve 23 is slidably connected to the boom 14 located below the radial rods 22, and the boom 14 and the sleeve 23 can only slide relative to each other and cannot rotate relative to each other. A plurality of crossbars 24 corresponding to the radial rods 22 are fixedly arranged radially on the outer surface of the sleeve 23, and an inner hook 7 is hinged at the outer end of each crossbar 24; the bottom end of the sleeve 23 is fixedly arranged with the centrifugal drive device 15, and the centrifugal drive device 15 is based on... The rotation of the boom 14 generates centrifugal force, driving the sleeve 23 to move up and down along the boom 14. In use, the actuator of the drive device 3 drives the lifting cylinder 10 to move. The lifting cylinder 10, through the gear 9, drives the boom 14 to move along the slide rail 11. Simultaneously, the gear 9 meshes with the rack 12, generating rotation, which in turn drives the boom 14 to rotate. The boom 14 drives the radial rod 22, sleeve 23, and crossbar 24 to rotate. The radial rod 22 and crossbar 24 drive the outer hook 6 and inner hook 7 to rotate, thereby driving the exhaust manifold 8 to rotate, achieving all-around shot blasting of the exhaust manifold 8. Simultaneously, the rotation of the boom 14 drives the centrifugal device to rotate, generating centrifugal force that drives the sleeve 23 to move up and down. The sleeve 23 drives the crossbar 24 to move up and down, and the crossbar 24 drives the inner hook 7 to move up and down. The up-and-down movement of the inner hook 7, in conjunction with the outer hook 6 (which remains at a constant height), adjusts the suspension posture of the exhaust manifold 8, allowing for more comprehensive shot blasting of the exhaust manifold 8.

[0026] In this embodiment, the centrifugal drive device 15 includes a follower disk 25 rotatably connected to the bottom end of the boom 14. The bottom end of the sleeve 23 is rotatably connected to a movable disk 27 via a ratchet 26. The movable disk 27 is slidably connected to the boom 14. A plurality of hinged rods 28 are hinged to the outer surface of the follower disk 25. Centrifugal rods 29 are hinged to the outer ends of the hinged rods 28. Centrifugal balls 30 are fixedly installed at the bottom ends of the centrifugal rods 29. The top ends of the centrifugal rods 29 are all hinged to the movable disk 27. During use, the boom 14 rotates, driving the movable disk 27 to rotate via the ratchet 26. The movable disk 27 then drives... The centrifugal rod 29 rotates, causing the centrifugal ball 30 to rotate (simultaneously, the centrifugal rod 29 drives the follower plate 25 to rotate with the hanging rod 14 via the hinge rod 28). The rotation of the centrifugal ball 30 generates centrifugal force, causing the centrifugal ball 30 to move upward. The upward movement of the centrifugal ball 30 causes the top of the centrifugal rod 29 to move downward. The top of the centrifugal rod 29 drives the movable plate 27 to move downward. The movable plate 27 drives the sleeve 23 to move downward. The sleeve 23 drives each inner hook 7 to move downward via the crossbar 24, while the height of the outer hook 6 remains unchanged, thus causing the exhaust manifold 8 to... The suspension posture changes; and because the drive device 3 drives the suspension cylinder 10 to reciprocate within the housing 1, the suspension rod 14 rotates reciprocally. This reciprocating rotation of the suspension rod 14 drives the sleeve 23 to rotate reciprocally. When the sleeve 23 rotates reciprocally, it can only drive the movable disc 27 to rotate in one direction via the ratchet 26. In the other direction, the sleeve 23 does not drive the movable disc 27 to rotate. Therefore, during the reciprocating rotation of the sleeve 23, when the sleeve 23 drives the movable disc 27 to rotate, the centrifugal ball 30 generates centrifugal force, causing the sleeve 23 to move downwards, thereby changing the suspension posture. When the suspension posture of the exhaust manifold 8 changes, and the rotation of the sleeve 23 cannot drive the movable disk 27 to rotate, the centrifugal ball 30 cannot generate centrifugal force. Under the action of gravity, the centrifugal ball 30 falls downward, causing the top of the centrifugal rod 29 to push the movable disk 27 to move upward. The movable disk 27 drives the sleeve 23 to move upward, and the sleeve 23 drives the inner hook 7 to move upward, so that the suspension posture of the exhaust manifold 8 returns to the previous state. In this way, the suspension posture of the exhaust manifold 8 changes back and forth, ultimately achieving the purpose of more effectively shot blasting the exhaust manifold 8.

[0027] In this embodiment, the ratchet 26 includes an inner rotor 31 and an outer rotor 32. The inner rotor 31 is fixedly disposed to the bottom end of the sleeve 23, and the outer rotor 32 is fixedly disposed to the movable disk 27. Several receiving grooves 33 are formed on the outer surface of the inner rotor 31. A pressure spring 34 is fixedly disposed in each receiving groove 33, and a ball 35 is fixedly disposed at the outer end of each pressure spring 34. Several driving grooves adapted to the balls 35 are formed on the inner side of the outer rotor 32. One side of the driving groove is an inclined surface 36, and the other side is a driving surface 37. In use, the lifting rod 14 drives the sleeve 23 to rotate, and the sleeve 23 carries... The inner rotor 31 rotates, driving several balls 35 to rotate. When the rotation direction causes the balls 35 to contact the driving surface 37, the inner rotor 31 drives the outer rotor 32 to rotate through the balls 35, and the outer rotor 32 drives the movable disk 27 to rotate. When the rotation direction causes the balls 35 to rotate towards the inclined surface 36, the balls 35 are forced into the receiving groove 33, causing the inner rotor to idle in the outer rotor 32, while the outer rotor 32 remains stationary. This keeps the movable disk 27 stationary, ultimately achieving the purpose that the sleeve 23 can only drive the movable disk 27 to rotate in one rotation direction when it reciprocates.

[0028] In this embodiment, a vertical bucket elevator 38 is provided on the rear side of the housing 1. The bottom end of the vertical bucket elevator 38 is connected to the bottom of the housing 1. A shot separation device 39 is provided on the top end of the vertical bucket elevator 38. The shot separation device 39 is used to separate steel shot and residue. Two hoses 40 are fixedly connected to the lower end face of the shot separation device 39. Two shot peening devices 2 are fixedly provided on the right side of the housing 1. The bottom ends of the two hoses 40 are respectively connected to the corresponding shot peening devices 2. In use, the shot peening device 2 sprays steel shot into the housing 1 to perform shot peening on the exhaust manifold 8. The steel shot and impurities fall to the bottom of the housing 1 and enter the vertical bucket elevator 38, and then enter the shot separation device 39. The shot separation device 39 separates the steel shot and impurities. The separated steel shot re-enters the shot peening device 2 through the hoses 40 to form a cycle. The separated impurities are discharged and centrally processed.

[0029] In this embodiment, the shot separation device 39 includes a separation housing 41. The top of the separation housing 41 is connected to the discharge port of the vertical bucket elevator 38. The vertical bucket elevator 38 transports steel shot from the bottom of the housing 1 into the separation housing 41. A guide plate 42 and a filter plate 43 are fixedly installed inside the separation housing 41. Two collection housings 44 are fixedly installed on the lower end face of the separation housing 41. The left collection housing 44 is located below the filter plate 43, and the right collection housing 44 is located below the guide plate 42. A channel is formed between the filter plate 43 and the guide plate 42 to communicate with the right collection housing 44. The lower end face of the left collection housing 44 is fixedly connected to the top ends of two hoses 40, and the lower end face of the right collection housing 44 is provided with an impurity discharge port.

[0030] In use, the vertical bucket elevator 38 conveys steel shot from the bottom of the housing 1 into the separation housing 41. The steel shot falls onto the guide plate 42 and slides onto the filter screen plate 43. The filter screen plate 43 filters out large particles of impurities, which enter the collection housing 44 on the right side through the channel and are discharged from the impurity outlet. Meanwhile, the fine steel shot falls below the filter screen plate 43 and enters the collection housing 44 on the left side, then enters the hose 40, and then enters the corresponding shot peening device 2.

[0031] In this embodiment, the vertical bucket elevator 38 is existing technology in the art and will not be described in detail here. A dust removal device is provided on one side of the body 50 of the vertical bucket elevator 38. The dust removal device includes a bag filter 45 and a filter cartridge 46. The bag filter 45 includes a collection hood 47. A separation space is provided on the upper part of the collection hood 47. The separation space is connected to the interior of the vertical bucket elevator 38. A connecting pipe 48 is fixedly connected to the upper end face of the collection hood 47. The connecting pipe 48 extends into the interior of the separation space. The connecting pipe 48 is away from the collection hood 47. One end is connected to the filter element 46; during use, the filter element 46 has a fan 49. When working, the fan 49 is turned on, and a vacuum is drawn inside the vertical bucket elevator 38 through the connecting pipe 48 and the collection hood 47. When the steel shot and impurities are lifted by the vertical bucket elevator 38, the fine particles and impurities inside are drawn into the collection hood 47. The fine particles and impurities in the air collide with the connecting pipe 48 inside the separation space and fall into the collection hood 47. The air enters the filter element 46 from the connecting pipe 48 for filtration again.

[0032] The function of the bag filter 45 is to first perform air separation on the steel shot and impurities when they are lifted by the vertical bucket elevator 38, so as to remove the fine particles and impurities inside.

[0033] In this embodiment, the filter cartridge filter 46 includes a body 50, inside which a plurality of filter cartridges 51 are disposed. A fan 49 is fixedly disposed on the upper end face of the body 50. The inlet of the fan 49 is connected to the interior of the body 50, and the outlet of the fan 49 is connected to the outside. The connection point between the connecting pipe 48 and the interior space of the body 50 is located below the filter cartridges 51. When in use, the fan 49 is started, and the air flow path is that the air flows out from the vertical bucket elevator 38 and enters the collection hood 47, the connecting pipe 48, the body 50, the filter cartridges 51 and the fan 49, and then is discharged to the outside.

[0034] In this embodiment, an I-beam rail 52 is fixedly installed on the front side of the vertical bucket elevator 38, and a gantry frame 53 is fixedly installed on the upper end face of the housing 1. The I-beam rail 52 and the gantry frame 53 are fixedly installed. The drive device 3 is installed on the I-beam rail 52. The drive device 3 can move back and forth on the I-beam rail 52 to achieve the purpose of driving the hoisting cylinder 10 to move back and forth.

[0035] In this embodiment, the driving device 3 includes a traction block 54, which is slidably connected to the I-beam rail 52. A winch is mounted on the traction block 54, and a steel wire rope 55 is wound around the winch. The hoisting cylinder 10 is suspended on the steel wire rope 55. Rotation of the winch drives the hoisting cylinder 10 to rise and fall via the steel wire rope 55. A traction rope is mounted on the traction block 54, and a traction machine is mounted on one side of the I-beam rail 52. The traction machine drives the traction block 54 to reciprocate on the I-beam rail 52 via the traction rope. Neither the traction machine nor the traction rope is shown in the diagram.

[0036] In this embodiment, the traction block 54 and the I-beam rail 52 are slidably connected in the following way: a moving block 56 is fixedly provided on the upper end surface of the traction block 54, and a roller is rotatably connected to the moving block 56. The moving block 56 moves left and right so that the roller rolls in the I-beam rail 52, so that the moving block 56 moves on the I-beam rail 52.

[0037] The shot peening device 2 is a standard technology in the field of shot blasting equipment, and will not be described in detail here.

[0038] In this embodiment, the inner end of each radial rod 22 is fixedly set with a shaft hoop, which is sleeved on the hanger rod 14. Several set screws are arranged radially on the shaft hoop. By screwing the set screws into contact with the hanger rod 14, the shaft hoop is fixed to the hanger rod 14. Several grooves are opened radially at the corresponding positions of the hanger rod 14, and each set screw is pushed into the corresponding groove. The purpose is to adjust the angle between the radial rod 22 and the hanger rod 14. The set screws and grooves are not shown in the figure.

[0039] In this embodiment, a diagonal brace 58 is fixedly provided between the radial trunk 22 and the outer hook 6, which makes the outer hook 6 more stable and secure.

[0040] The working principle of this invention: When the hook assembly 5 is located outside the housing 1, the exhaust manifold 8 is hooked onto the outer hook 6 and the inner hook 7. Then, the traction machine drives the traction block 54 to move into the housing 1 via the traction rope. When the exhaust manifold 8 moves into the housing 1, the housing door is closed. Then, the shot peening device 2, the vertical bucket elevator 38, and the dust removal device are activated. The shot peening device 2 sprays steel shot onto the exhaust manifold 8 inside the housing 1. At the same time, the traction machine drives the traction block 54 to reciprocate within the housing 1. The lifting cylinder 10 drives the gear 9 and the lifting rod 14 to reciprocate. The lifting rod 14 drives the exhaust manifold 8 to reciprocate via the outer hook 6 and the inner hook 7. At the same time, the gear 9 reciprocates and meshes with the rack 12. The gear 9 rotates, and the gear 9 drives the lifting ring to rotate. The lifting ring drives the exhaust manifold 8 to rotate. At the same time, the lifting rod 1... The rotation of the 4-axis drives the movable disc 27 to rotate, which in turn drives the centrifugal rod 29 to rotate. The centrifugal rod 29 then drives the centrifugal ball 30 to rotate (simultaneously, the centrifugal rod 29 drives the follower disc 25 to rotate with the suspension rod 14 via the hinge rod 28). The rotation of the centrifugal ball 30 generates centrifugal force, causing the centrifugal ball 30 to move upward. The upward movement of the centrifugal ball 30 causes the top of the centrifugal rod 29 to move downward. The top of the centrifugal rod 29 drives the movable disc 27 to move downward. The movable disc 27 drives the sleeve 23 to move downward. The sleeve 23 drives each inner hook 7 to move downward via the crossbar 24, while the height of the outer hook 6 remains unchanged. This changes the suspension posture of the exhaust manifold 8. The exhaust manifold 8 moves within the housing 1 by reciprocating movement, rotation, and repeated adjustment of the suspension posture, achieving more efficient shot blasting.
