Description

Technical Field

[0001] The present invention relates to the technical field of shot blasting equipment, in particular to a shot blasting processing system. Background Art

[0002] After processing, there will be impurities on the surface of metal workpieces, such as oxide layers and burrs, which generally need to be processed using shot blasting equipment. The shot blasting equipment shoots shot blasting balls at high speed and hits the surface of the metal workpiece, thereby causing impurities to fall off the surface of the metal workpiece. In actual processing, for larger metal workpieces, the metal workpieces are generally hung in a hoisting manner and then sent to the inside of the equipment for processing. At this time, the shot blasting balls used can be steel balls with a slightly larger diameter. For very small metal workpieces, such as standard spring washers, this method is not suitable for processing. A crawler shot blasting machine provided by the Chinese invention application with publication number CN118721039A can be used, including a frame, a shot blasting chamber installed on the frame, a conveyor belt arranged in the shot blasting chamber for placing metal workpieces, and a conveyor installed in the shot blasting chamber for conveying A support roller with support and a shot blaster installed on the top of the shot blasting chamber, the discharge end of the shot blaster is connected to the inner cavity of the shot blasting chamber, there are mesh holes on the conveyor belt, the inner arc surface of the conveyor belt is called the upper conveying part, and the outer arc surface of the conveyor belt is called the lower conveying part. It also includes a pressing roller group that presses against the lower conveying part, and an accumulation space is formed between the upper conveying part and the lower conveying part. The pressing roller group includes a first pressing roller that abuts against the side of the lower conveying part facing the accumulation space, and the height of one end of the first pressing roller is lower than the height of the other end. There is a gap between the lower conveying part and the side wall of the shot blasting chamber, and the gap connects the accumulation space with the lower side of the lower conveying part. This application can improve the recovery efficiency of the projectiles and reduce the accumulation of projectiles between the two layers of conveyor belts, which affects the normal operation of the equipment. Due to the small size of the metal workpiece, steel sand with a smaller particle size is used. During the actual operation, steel sand may be stuck in the mesh, or the internal roller group and other components may be stuck, resulting in the need for frequent cleaning, thereby reducing the overall shot blasting efficiency. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a shot blasting system, which solves the problem in the prior art that when shot blasting small-sized metal workpieces, steel sand and impurities may cause internal components to get stuck and reduce the overall shot blasting efficiency.

[0004] According to an embodiment of the present invention, a shot blasting system includes: a shot blasting box, a door body is arranged on one side of the shot blasting box, a shot blasting machine is installed on the top of the shot blasting box, and the shot blasting machine has a spray port located in the shot blasting box and arranged downward; a vibration plate is located directly below the shot blasting machine, a plurality of small holes are opened on the vibration plate, and a guide outlet is also arranged on the side of the vibration plate facing the door body; a vibration cross bar is installed in the shot blasting box, and one end of the vibration cross bar passes through the outside of the shot blasting box and is connected to a vibration motor, and the vibration plate is against the vibration cross bar; a fixed suspension rod is also fixedly arranged in the shot blasting box, and a telescopic suspension rod is arranged to move back and forth toward the door body, the fixed suspension rod is close to the door body and is connected to the vibration plate by a first cable, and the telescopic suspension rod is away from the door body and is connected to the vibration plate by a second cable, and the telescopic suspension rod can also rotate to wind the second cable.

[0005] In the above embodiment, after the door body is opened, the small-sized metal workpiece is put into the vibration disk, and then the door body is closed, and the equipment is started to start shot blasting. During the processing, the first cable and the second cable are in an untensioned state, and the operation of the vibration motor causes the vibration cross bar to vibrate, thereby indirectly causing the vibration disk of the belt to vibrate, and the steel grit sprayed by the shot blaster impacts the metal workpiece below. The vibration makes it more efficient to separate impurities on the metal workpiece. At the same time, the steel grit and impurities are also easier to pass through the small holes and separate from the metal workpiece. After a period of processing, the vibration motor and the shot blaster are stopped, the door body is opened, and the telescopic boom drives the second cable to move outward, and then rotates to make the second cable wind up, and the end of the vibration disk away from the outlet is raised, so that the metal workpiece can be smoothly discharged from the outlet, and then reset to complete a round of operations. During the process, steel grit and impurities are not easy to cause blockage of internal components, thereby solving the problem in the prior art that steel grit and impurities may cause internal components to get stuck when shot blasting small-sized metal workpieces, reducing the overall shot blasting efficiency.

[0008] Furthermore, a third support plate is fixedly connected to the shot blasting box, and the first drive motor is slidably arranged on the third support plate.

[0009] Furthermore, the vibration plate is provided with a pair of horizontal holes located on both sides of the guide outlet, a first pull rod is passed through the two horizontal holes, and both ends of the first pull rod are respectively fixedly connected to limit blocks located outside the vibration plate.

[0010] Furthermore, the first cable comprises a pair, one end of the first cable is rotatably connected to the fixed suspension rod through a first rotating ring, and the other end of the first cable is rotatably connected to one end of the first pull rod through a second rotating ring, and the second rotating ring is located inside / outside the vibration plate.

[0011] Furthermore, a mounting block facing the door body is fixedly connected in the shot blasting box, and a side of the mounting block facing the door body is telescopically connected to a back plate facing the door body. A pair of baffles are fixedly connected to both ends of the back plate, and the end of the vibration disk facing away from the outlet can be located between the space enclosed by the back plate and the two baffles.

[0012] Furthermore, a mounting groove is recessed in the bottom surface of the mounting block, a fixing column is fixedly connected in the mounting groove, a sliding cylinder is fixedly connected on the abutment plate, and the sliding cylinder slides into the mounting groove and is arranged on the fixing column, and a spring is also sleeved on the fixing column to resist the sliding cylinder and the inner wall of the mounting groove.

[0013] Furthermore, a guide hole located above the mounting groove is also provided on the mounting block, and the abutment plate is also fixedly connected with a guide rod slidably connected to the guide hole, and the guide hole is also communicated with the mounting groove.

[0014] Furthermore, the end surface of the sliding cylinder located in the installation groove is also fixedly connected to a limiting plate, the fixing column slides through the limiting plate and the spring abuts against the limiting plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The treatment is carried out in a combination of vibration and shot blasting steel grit jetting, so that the impurity removal effect is better. At the same time, the combination of vibration and jet impact during the treatment process also allows impurities to be separated more smoothly. Steel grit and impurities can pass through the small holes on the vibration plate and be separated from the metal workpiece more efficiently, and are not prone to clogging of internal components, thereby reducing the maintenance frequency of internal components. This solves the problem in the prior art that steel grit and impurities may cause internal components to get stuck and reduce the overall shot blasting efficiency when shot blasting small-sized metal workpieces.

[0026] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0028] like Figure 1-7As shown, the present embodiment provides a shot blasting system, which comprises: a shot blasting box body 1, a door body 2 is arranged on one side of the shot blasting box body 1, a shot blasting machine 4 is also installed on the top of the shot blasting box body 1, and the shot blasting machine 4 has an injection port located in the shot blasting box body 1 and arranged downwardly, and steel sand is sprayed downwardly from the injection port during shot blasting; a vibration plate 5 is located directly below the shot blasting machine 4, a plurality of small holes are opened on the vibration plate 5, and a guide port 9 is also arranged on the side of the vibration plate 5 facing the door body 2. More specifically, the vibration plate 5 comprises a bottom plate 6, a back plate 7 and a pair of side plates 8 located on both sides, and the guide port 9 is arranged on a side surface close to the door body 2, and is formed by the bottom plate 6 obliquely tilted upward and surrounded by the two side plates 8; a vibration cross bar 10 is installed in the shot blasting box body 1, and one end of the vibration cross bar 10 passes through the outside of the shot blasting box body 1 and is connected to a vibration motor 11, and the vibration plate 5 is against the vibration cross bar 10, and the vibration cross bar 10 can be a pair, which are respectively located below the two ends of the vibration plate 5 and are connected to the vibration plate 5. The bottom plates 6 can be in surface contact with each other, so as to avoid damage to the bottom plate 6 caused by excessive impact. At the same time, a number of small holes are set on the bottom plate 6, and these small holes can be not set at the position directly above the vibrating cross bar 10, so as to avoid more steel sand being repeatedly impacted on the vibrating cross bar 10; a fixed suspension rod 12 is also fixedly arranged in the shot blasting box body 1, and a telescopic suspension rod 13 is reciprocated in the direction of the door body 2. The fixed suspension rod 12 is close to the door body 2 and is connected to the vibrating disk 5 through a first cable 14, and the telescopic suspension rod 13 is away from the door body 2 and is connected to the vibrating disk 5 through a second cable 15. The telescopic suspension rod 13 can also rotate to wind the second cable 15. The first cable 14 and the second cable 15 can be steel cables, which can adapt to the vibration of the vibrating disk 5 and can also carry the vibrating disk 5 and the metal workpieces therein. In more detail, the side plates 8, the back plate 7 and the bottom plate 6 are tilted upward, so as to block the metal workpieces and prevent them from falling during the processing;When processing, first open the door body 2 and then put the small-sized metal workpiece into the vibration plate 5 (the size of the metal workpiece is larger than the small hole and will not pass through the small hole), then close the door body 2, start the equipment to start shot blasting, during the processing, the first cable 14 and the second cable 15 are in an untensioned state, the vibration motor 11 is set to run to make the vibration cross bar 10 vibrate, thereby indirectly vibrating the vibration plate 5, and the steel sand sprayed by the shot blaster 4 impacts the metal workpiece below, and the vibration makes it more efficient to separate the impurities on the metal workpiece, and the steel sand and impurities are also easier to pass through the small hole Separated from the metal workpiece, after a period of processing, stop the vibration motor 11 and the shot blaster 4, open the door body 2, and the telescopic suspension rod 13 drives the second cable 15 to move outward, and then rotates to make the second cable 15 wind up, and the end of the vibration plate 5 away from the outlet 9 is raised, so that the metal workpiece can be smoothly discharged from the outlet 9, and then reset to complete a round of operation. During the process, steel grit and impurities are not easy to cause internal components to be blocked, thus solving the problem in the prior art that steel grit and impurities may cause internal components to get stuck and reduce the overall shot blasting efficiency when small-sized metal workpieces are shot blasted. ;

[0029] like Figure 1-3 As shown, the cross section of the vibration cross bar 10 can be square and can be a pair. Both ends of the vibration cross bar 10 pass through the shot blasting box 1, one end is connected to the vibration motor 11, and the other end can be connected to the counterweight 16 to balance the two ends. It can also be replaced with another identical vibration motor 11; in more detail, a support plate 17 can also be fixedly connected to the outer wall of the shot blasting box 1 to provide upward support for the vibration motor 11 or the counterweight 16.

[0030] like Figure 1 , 2 As shown, similar to the prior art, a receiving trough 24 is provided in the shot blasting box 1 below the vibrating plate 5 for catching the steel sand and impurities, which are then drawn out to the cleaning equipment for cleaning through the external exhaust device 23, and the steel sand is reused.

[0031] like Figure 1 , 2As shown in , 4, 5 and 7, the vibration plate 5 is also provided with a pair of horizontal bars 19 located on both sides of the guide outlet 9, a first pull rod 20 is passed between the two horizontal bars 19, and the two ends of the first pull rod 20 are respectively fixedly connected with limit blocks 21 located outside the vibration plate 5, the limit blocks 21 are outside the two side plates 8, so that the first pull rod 20 will not be detached from the vibration plate 5, and the horizontal bars 19 allow the first pull rod 20 to move laterally during the discharging process, so that the guide outlet 9 moves outward in an inclined manner to the lower edge of the door opening 3. In more detail, an inclined plate 22 is also fixedly connected to the lower edge of the door opening 3, and the higher end extends toward the guide outlet 9. During the discharging process, the upwardly tilted bottom surface of the bottom plate 6 may be against the inclined plate 22 (if there is a large amplitude of shaking), thereby limiting the excessive outward movement of the vibration plate 5. At the same time, when the vibration plate 5 is tilted to a larger angle, some metal workpieces may first fall onto the inclined plate 22 to avoid falling directly into the receiving trough 24 at the bottom of the shot blasting box 1.

[0032] like Figure 1 , 2 , 4 and 5, the first cables 14 can be two, the second cable 15 can be one, the two ends of the fixed suspension rod 12 are respectively fixedly connected to the inner wall opposite to the shot blasting box 1, one end of the first cable 14 is rotatably connected to the fixed suspension rod 12 through the first rotating ring 18, and the other end of the first cable 14 is rotatably connected to one end of the first rod 20 through the second rotating ring 25. The second rotating ring 25 is located inside the vibration plate 5 / outside the vibration plate 5, that is, the two ends of the first rod 20 can extend beyond the two side plates 8, the second rotating ring 25 can be connected to the first rod 20 on the outside, and can also be connected to the first rod 20 on the inside, and the first cable 14 is connected to the middle position of the back plate 7. It is best to form an isosceles triangle between the three, so that it can be relatively more stable during operation.

[0033] like Figure 1 , 2As shown in Figure 5, the shot blasting box body 1 is also fixedly connected with a mounting block 26 facing the door body 2, and the mounting block 26 is telescopically connected to a side of the door body 2 facing the door body 2 with a backing plate 27 facing the door body 2. The backing plate 27 can be connected to the back plate 7, and a pair of baffles 28 are also fixedly connected at both ends of the backing plate 27. The end of the vibration plate 5 away from the outlet 9 can be located between the space enclosed by the backing plate 27 and the two baffles 28. The baffle 28 is provided to provide a limit at the position opposite to the back plate 7, and the two backing plates 27 are located outside the side plates 8 on both sides to provide a limit, and cooperate with the vibration cross bar 1 below 0 and the first cable 14 and the second cable 15, so that the vibration plate 5 can vibrate relatively stably within a certain range, and will not slide off the vibration cross bar 10 due to dislocation caused by vibration; specifically, the bottom surface of the mounting block 26 is recessed with a mounting groove 29, and a fixed column 30 is fixedly connected in the mounting groove 29, and a sliding cylinder 31 is fixedly connected on the abutment plate 27, and the sliding cylinder 31 slides into the mounting groove 29 and the sliding cylinder 31 is arranged on the fixed column 30, and the fixed column 30 is also sleeved with a spring 32 that abuts against the sliding cylinder 31 and the inner wall of the mounting groove 29, The cooperation between the fixed column 30 and the sliding cylinder 31 makes the plate 27 move only in the lateral direction, and the spring 32 provides a reset function. In this way, when the vibration plate 5 vibrates, if the plate 27 is hit in the lateral direction, the spring 32 plays a buffering role, so that the plate 27 moves forward and backward to adapt to the impact and avoids the impact being too intense. The baffles 28 on both sides can be reserved with a long distance (not against each other), and under normal circumstances, they will not collide with the side plates 8, which can prevent the vibration plate 5 from accidentally moving in the lateral direction without affecting the normal vibration of the vibration plate 5. In more detail, the mounting block 26 A guide hole 33 is also provided above the mounting groove 29. The push plate 27 is also fixedly connected to a guide rod 34 that is slidably connected to the guide hole 33. The guide hole 33 is also connected to the mounting groove 29. The guide hole 33 and the guide rod 34 provided above further improve the stability of the forward and backward movement of the push plate 27. The end surface of the sliding cylinder 31 located in the mounting groove 29 is also fixedly connected to a limit plate 49. The fixed column 30 slides through the limit plate 49 and the spring 32 abuts against the limit plate 49. The limit plate 49 can prevent the push plate 27 from being completely disengaged from the mounting block 26.

[0034] like Figure 1 , 2, 5 and 6, a first driving motor 35 is also movably installed outside the shot blasting box 1, and the output shaft of the first driving motor 35 is fixedly connected to the telescopic boom 13. A first supporting plate 36 is also fixedly connected to the shot blasting box 1, and a sliding frame 37 is provided on the first supporting plate 36. A sliding block 38 that can slide in the sliding frame 37 is fixedly connected to the first driving motor 35. A second driving motor 39 is also fixedly installed on the shot blasting box 1, and the output shaft of the second driving motor 39 is fixedly connected to a driving shaft 40, and the driving shaft 40 is connected to the sliding block The second drive motor 39 is provided with a threaded through hole, and the drive shaft 40 is provided with a threaded section. The drive shaft 40 is threadedly passed through the threaded through hole. When the second drive motor 39 is running, the drive shaft 40 is rotated, and the slide block 38 is slidably arranged in the slide frame 37, so that the slide block 38 can be slid. In more detail, the slide frame 37 can also be provided with convex strips 41 on both sides, and the two sides of the slide block 38 are provided with grooves 42 for the convex strips 41 to slide. In this way, the operation of the slide block 38 is more Furthermore, a second support plate 43 is fixedly connected to the shot blasting box 1, and a U-shaped notch 44 is provided on the second support plate 43. The telescopic suspension rod is slidably supported on the second support plate 43 and the second cable 15 can move in and out of the notch 44. The notch 44 provides a moving space for the second cable 15. The second support plate 43 provides an upward sliding support for the telescopic suspension rod 13 in the shot blasting box 1, which can improve the pulling stability of the second cable 15 on the vibration plate 5. In more detail, in the middle of the back plate 7 A pair of mounting seats 45 are fixedly connected at the position, and a second pull rod 46 is fixedly connected between the two mounting seats 45. The lower end of the second cable 15 is rotatably connected to the second pull rod 46 through a third rotating ring 47. In this way, when it is necessary to discharge the material, the telescopic suspension rod 13 is moved toward the door body 2 through the second driving motor 39. After the back plate 7 and the abutment plate 27 are separated, the first driving motor 35 causes the telescopic suspension rod 13 to rotate and convolute the second cable 15, so that the lower end of the outlet 9 of the vibration plate 5 is obliquely arranged at the opening of the door body 2 (i.e., the lower edge of the door opening 3, such as Figure 2 In more detail, a third support plate 48 may be provided outside the shot blasting box 1 to provide upward sliding support for the first drive motor 35.
