Description

Technical Field

[0002] Shot blasting equipment is an efficient mechanical device used for surface treatment of metal or other materials. It is mainly composed of a shot blaster, a shot circulation system, a casing conveying system, and a sealing and protective device. As the core component, the shot blaster uses a high-speed rotating impeller to forcefully project the shot onto the surface of the casing to be treated, effectively removing scale, rust and impurities, and making the surface have a suitable roughness to enhance the adhesion of subsequent coatings. The shot circulation system is responsible for the storage, lifting, separation and recovery of the shot to ensure the recycling of qualified shot. The casing conveying system allows the casing to pass through the shot blasting area at a uniform speed to ensure the uniformity of the treatment. The sealing and protective device prevents the splashing of shots and the escape of dust during the shot blasting process, which not only protects the safety of operators but also reduces environmental pollution. It plays an extremely critical role in the surface pretreatment process in many fields such as machinery manufacturing, automobile industry, aerospace, etc.

[0003] When the projectile is powerfully thrown onto the surface of the casing to be processed, it may collide with the surface protrusions of the product, causing the projectile to break into pieces.

By rotating the handle to drive the rotating shaft three to rotate half a circle, the outer frame will face downward, the gravity of the shovel plate will be greater than the pulling force of the telescopic spring, the shovel plate will move downward and move the brush, so that the dust on the brush and the dust in the outer frame will fall off.

[0025] 4. The present invention is provided with a shot blasting unit. After the projectile enters the storage bin through the projectile inlet pipe, it will enter the outer plate through the projectile inlet port. Then, the servo motor 2 will drive the rotating shaft 4 and the blade fan to rotate.

Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0041] Example 1, using Figure 1-Figure 13 A shot blasting device and a shot blasting process for casing surface treatment according to an embodiment of the present invention are described as follows.

[0042] like Figure 1-Figure 3As shown, a shot blasting device for casing surface treatment of the present invention comprises: a support leg 1, a shot blasting box 2 is fixedly connected to the top of the support leg 1, a switch device 3 is fixedly connected to the outer surface of the shot blasting box 2, a sealing door 4 is fixedly connected to the output end of the switch device 3, the outer surface of the sealing door 4 is rotatably connected to the outer surface of the shot blasting box 2, a shot blasting unit 5 is fixedly connected to the front of the shot blasting box 2, a processing unit 6 is fixedly connected to the bottom of the shot blasting box 2, a rack 8 is fixedly connected to the top of the shot blasting box 2, and a shot outlet channel 9 is provided on the side of the shot blasting box 2 close to the shot blasting unit 5;

[0043] A loading unit 7, which is arranged on the top of the shot outlet box and is used to drive the product to be shot blasted into the shot blasting box 2;

[0044] When the present invention is working, the loading mechanism will drive the shot blasting product into the shot blasting box 2, and then the shot blasting unit 5 will shot blast the product to remove iron filings on the surface of the product. After that, the projectiles after the impact will fall into the processing unit 6, and the processing unit 6 will process and recycle the projectiles.

[0045] like Figure 4-Figure 5 As shown, the processing unit 6 includes a bottom plate 61, the top of the bottom plate 61 is evenly provided with inclined blocks 62, both ends of the inclined blocks 62 are fixedly connected to the top of the bottom plate 61, and the top of the inclined blocks 62 is evenly provided with protruding blocks 69, the bottom of the shot blasting box 2 is fixedly connected with a support plate 1 63, the bottom of the support plate 1 63 is fixedly connected with a servo motor 1 64, the outer surface of the bottom plate 61 is fixedly connected with a grinding mechanism 65, and gaps 66 are provided between adjacent inclined blocks 62, and a cleaning mechanism 67 is fixedly connected to the side of the bottom plate 61 away from the servo motor 1 64, and a collecting plate 68 is placed at the bottom of the cleaning mechanism 67;

[0046] After the shot blasting hits the product to be blasted, it will fall onto the inclined block 62 of the bottom plate 61 due to gravity. Since the shot may be broken after colliding with the product, such shot does not need to be recovered. Normal shot is round and will fall with the inclined plate and fall from the gap 66 to the subsequent grinding mechanism 65 for grinding. However, the friction between the broken shot and the inclined block 62 will become greater and will be blocked by the protruding block 69, thereby separating most of the broken shot from the normal shot.

[0047] like Figure 6-Figure 7As shown, the grinding mechanism 65 includes a transfer plate 651, the inner wall of the transfer plate 651 is rotatably connected to a disk 1 653, the output end of the servo motor 1 64 is fixedly connected to a rotating shaft 1 652, the end of the rotating shaft 1 652 away from the servo motor 1 64 is fixedly connected to a disk 2 654, the outer surface of the disk 2 654 is sleeved with a chain 655, the outer surface of the disk 1 653 is fixedly connected to a rotating shaft 2 656, the outer surface of the rotating shaft 2 656 is fixedly connected to a grinding rod 657, the end of the disk 2 654 away from the rotating shaft 1 652 is fixedly connected to a screw rod 658, the outer surface of the screw rod 658 is threadedly connected to a moving block 659, the top of the moving block 659 is fixedly connected to a push plate 6510, and the inner wall of the bottom plate 61 is fixedly connected to a resisting top plate 6511.

[0048] The servo motor 64 will drive the shaft 1 652 to rotate, and then drive the disc 1 653 to rotate. Along with the transmission of the chain 655 and the disc 2 654, the shaft 2 656 will rotate, so that the grinding rod 657 will grind the projectile to remove the oxide scale and rust attached to the projectile when it contacts the surface of the product to be polished. The projectile will then fall onto the resisting bottom plate 61. The rotation of the shaft 1 652 will also drive the screw 658 to rotate, and then the moving block 659 will move along the screw 658, so that the resisting top plate 6511 will push the projectile to move, and it will fall out from the shot outlet 679 and enter the subsequent cleaning mechanism 67.

[0049] The top of the bottom plate 61 is fixedly connected to the bottom of the shot blasting box 2 , and the outer surface of the transfer plate 651 is fixedly connected to the outer surface of the bottom plate 61 .

[0050] The outer surface of the chain 655 is sleeved with the outer surface of the disc 1 653 , and the bottom of the push plate 6510 is slidably connected with the outer surface of the resisting top plate 6511 .

[0051] like Figure 8 As shown, the cleaning mechanism 67 includes a fixed block 671, the outer surface of the fixed block 671 is rotatably connected to a rotating shaft 3 672, the end of the rotating shaft 3 672 away from the fixed block 671 is fixedly connected to a handle 673, outer frames 674 are symmetrically arranged on both sides of the rotating shaft 3 672, a circular notch 675 is arranged at the bottom of the outer frame 674, a telescopic spring 676 is fixedly connected to the bottom of the outer frame 674, a shovel plate 677 is fixedly connected to the top of the telescopic spring 676, the inner wall of the outer frame 674 is evenly provided with brushes 678, and a pill outlet 679 is arranged on the side of the bottom plate 61 close to the fixed block 671.

[0052] After the projectile falls out of the projectile outlet 679, it will fall into the outer frame 674. During the falling process, the projectile will come into contact with the brush 678, and the brush 678 will brush off the dust and impurities on the projectile, and finally fall on the shovel plate 677. The telescopic spring 676 will resist the sliding speed, so that the projectile will finally fall out of the circular notch 675 along the shovel plate 677 and finally fall onto the collecting plate 68. After working for a period of time, a certain amount of dust will accumulate in the outer frame 674. By rotating the handle 673, the rotating shaft three 672 will rotate half a circle, so that the outer frame 674 faces downward, and the gravity of the shovel plate 677 will be greater than the pulling force of the telescopic spring 676. The shovel plate 677 will move downward and move the brush 678, so that the dust on the brush 678 and the dust in the outer frame 674 will fall off.

[0053] The outer surface of the fixing block 671 is fixedly connected to a side of the bottom plate 61 away from the servo motor 1 64 .

[0054] The specific workflow is as follows:

[0055] During operation, after the shot is thrown out from the shot blasting unit 5 and collides with the product, it will fall onto the inclined block 62 of the bottom plate 61. The normal shot, which is round in shape, will fall along with the inclined plate and fall from the gap 66 to the subsequent grinding mechanism 65 for grinding. However, the friction between the broken marbles and the inclined block 62 will increase and the falling will be blocked by the protruding block 69, so that most of the broken shots are separated from the normal shots. Then, the servo motor 1 64 will drive the shaft 1 652 to rotate, and then drive the disc 1 653 to rotate. Along with the transmission of the chain 655 and the disc 2 654, the shaft 2 656 will rotate, so that the grinding Rod 657 grinds the projectile to remove the oxide scale and rust attached to the projectile when it contacts the surface of the product to be polished. At the same time, the rotation of shaft 1 652 will also drive the screw 658 to rotate, thereby causing the moving block 659 to move along the screw 658, so that the resisting top plate 6511 pushes the projectile to move and fall out from the projectile outlet 679. Finally, the projectile will come into contact with the brush 678 during the falling process. The brush 678 will brush off the dust and impurities on the projectile, and finally fall on the shovel plate 677. The telescopic spring 676 will resist the sliding speed, so that the projectile will finally fall out of the circular notch 675 along the shovel plate 677 and finally fall onto the collecting plate 68.
