Description

Technical Field

[0001] The present invention relates to the technical field of sandblasting deburring equipment, and specifically relates to a sandblasting deburring device for steel casting processing. Background Art

[0002] The sandblasting deburring technology is an efficient surface treatment method. By high-speed jetting abrasive particles to impact and grind the surface of the workpiece, it can remove surface defects such as burrs, rust, and oxide layers. This technology is widely used in fields such as metal processing, automobile manufacturing, and aerospace. The sandblasting process involves equipment such as sandblasting machines, compressed air systems, and abrasive recycling systems, as well as various sandblasting media such as quartz sand, steel sand, and glass beads. During operation, parameters such as sandblasting pressure, flow rate, and nozzle distance need to be adjusted to achieve the best treatment effect. Although the sandblasting technology has the advantages of simple operation and high efficiency.

[0003] In the prior art, during the sandblasting process of steel castings, the burrs and rust on the surface of the steel castings are ground off. At this time, the sand will fall into the storage box together with the burrs or rust and be mixed together. When the grinding is finished, the staff needs to take out the storage box and separate the sand and burrs inside. However, the separation process is slow and reduces the grinding efficiency.

[0017] The present invention has the following beneficial effects:

[0018] Through the setting of the fixing mechanism in the present invention, first, the steel casting is placed on the surface of the placing plate. The weight of the steel casting will cause the placing plate to move downward. When the placing plate moves downward, it will squeeze the supporting telescopic rod to contract downward. When the placing plate moves downward, it will push the lower pull plate to move downward. When the lower pull plate moves downward, it will pull the push plate to move downward. When the push plate moves downward, the angle between the push plate and the bent plate will change. When the push plate moves, it will push the bent plate to move towards each other. When the bent plate moves, it will drive the sliding plate to move towards the inside of the chute plate. When the bent plate moves, it will push the fixing rings to move towards each other and contact the outer wall of the steel casting, thereby fixing the steel casting and avoiding the phenomenon of deviation due to the vibration generated during the sandblasting process. When the bent plate moves, it will squeeze the return spring. When the steel casting is sandblasted and removed, the bent plate will be reset to its original position by the return spring, achieving the clamping and fixing of the steel casting, so that the steel casting is more stable during the grinding process.

[0019] In the present invention, by providing a sandblasting mechanism, when the pull-down plate moves downward, it will pull the extrusion rod downward. When the extrusion rod moves, it will extrude the stress plate. When the stress plate is extruded, it will push the dust-proof covers to move towards each other and merge together, thereby achieving the effect of isolating dust during sandblasting and also preventing the sand from splashing due to the impact force generated during sandblasting. When the dust-proof covers move, they will pull the elastic extension rods to extend towards each other. At this time, start the sand suction pump to extract the sand inside the storage funnel through the sand suction pipe, and then transport the sand to the inside of the sandblaster through the sand outlet pipe. Then start the sandblaster and start sandblasting through the nozzle. At this time, start the motor to drive the rotating shaft to rotate. When the rotating shaft rotates, it will drive the sandblaster to rotate. The sandblaster drives the sandblasting pipe and the nozzle to rotate, which can achieve uniform sandblasting of the steel casting and improve the grinding efficiency. At this time, the sand sprayed out will fall into the inside of the drainage funnel. Since the surface of the placement plate is provided with leakage holes, the probability of the sand flowing downward is greatly increased. When the sand flows into the inside of the drainage funnel, it will be drained to the surface of the filter plate through the drainage funnel. The sand and burrs are separated by the filter plate. Finally, the sand flows into the inside of the storage funnel, and finally the sand is pumped out by the sand suction pump for grinding. Since the surface of the storage frame is provided with a pouring plate, when the material in the storage funnel is less, the material can be diverted to the inside of the storage funnel through the pouring plate, thereby achieving the recycling of the sand, replacing the manual filtering of the sand, improving the grinding efficiency, and saving the cost of using sand.

[0020] In the present invention, by providing a cleaning mechanism, when the dust-proof covers move, they will drive the push frames to move towards each other. When the push frames move, they will extrude the limit springs, thereby limiting the push frames and preventing the surfaces of the push frames from contacting the surface of the workbench. When the push frames move, they will extrude the elastic frames. When the elastic frames are extruded, the middle part will be bent. When the elastic frames are bent, they will push the scraping plates to move towards each other on the surface of the filter plate, thereby concentrating the burrs on the surface of the filter plate. When the scraping plates move, they will drive the curved plates to move towards each other. When the curved plates move, they will extrude the driven plates. When the driven plates are extruded, they will push the cleaning plates to slide towards each other on the inner wall of the moving groove and clean the burrs on the surface of the filter plate. At the same time, when the scraping plates move, they will contract the cleaning plates towards each other. When the cleaning plates move, they will extrude the elastic plates. When the elastic plates are extruded, the middle part will bend downward. When the elastic plates are bent, they will push the expansion rods downward and expand towards each other. When the expansion rods move, they will push the opening and closing doors downward and expand towards each other, opening the opening and closing doors and cleaning the burrs concentrated by the cleaning plates and the scraping plates into the inside of the storage box. Since the surface of the storage frame is provided with a handle, when the storage box is full of burrs, the storage box can be pulled out and emptied, thereby achieving the centralized storage of the filtered burrs.

[0021] Of course, it is not necessary for any product implementing the present invention to achieve all of the above - mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

The surface of the storage frame 5 is fixedly connected to a sand suction pump 40. At this time, the sprayed sand will fall into the interior of the drainage funnel 3. Since the surface of the placement plate 18 is provided with a material leakage hole, the probability of the sand flowing downward is greatly increased. When the sand flows into the interior of the drainage funnel 3, the sand is drained to the surface of the filter plate 6 through the drainage funnel 3.

[0045] The cleaning mechanism 50 includes a pushing frame 51. When the dust shield 37 moves, it will drive the pushing frame 51 to move towards each other. A limiting spring 52 is fixedly connected to the surface of the pushing frame 51.

A handle is fixedly connected to the surface of the storage box 61, and the burrs concentrated by the cleaning plate 56 and the scraping plate 54 are cleaned into the storage box 61. Since a handle is provided on the surface of the storage frame 5, when the storage box 61 is full of burrs, the storage box 61 can be pulled out and emptied, thus achieving centralized storage of the filtered burrs.

[0047] During use, first place the steel casting on the surface of the placement plate 18. The weight of the steel casting will cause the placement plate 18 to move downward.

When the bent plate 13 moves, it will squeeze the return spring 15. When the steel casting is sandblasted and removed, the return spring 15 will reset the bent plate 13 to its original position. When the lower pull plate 17 moves downward, it will pull the extrusion rod 39 downward. When the extrusion rod 39 moves, it will squeeze the stress plate 38. When the stress plate 38 is squeezed, it will push the dust-proof covers 37 to move towards each other and merge together, thereby isolating the dust during sandblasting and also preventing the sand from splashing due to the impact force during sandblasting. When the dust-proof covers 37 move, they will pull the elastic extension rods 36 to extend towards each other. At this time, start the sand suction pump 40 to extract the sand inside the storage funnel 7 through the sand suction pipe 42, and then transport the sand to the inside of the sandblasting machine 33 through the sand discharge pipe 41. Then start the sandblasting machine 33 to start sandblasting through the nozzle 35. At this time, start the motor 31 to drive the rotating shaft 32 to rotate. When the rotating shaft 32 rotates, it will drive the sandblasting machine 33 to rotate. The sandblasting machine 33 drives the sandblasting pipe 34 and the nozzle 35 to rotate, which can achieve uniform sandblasting of the steel casting and improve the grinding efficiency. At this time, the sprayed sand will fall into the drainage funnel 3. Since the surface of the placement plate 18 is provided with leakage holes, the probability of the sand flowing downward is greatly increased. When the sand flows into the drainage funnel 3, it will be drained to the surface of the filter plate 6 through the drainage funnel 3. The sand and burrs are separated by the filter plate, and finally the sand flows into the storage funnel 7. Finally, the sand is pumped out by the sand suction pump 40 for grinding. Since the surface of the storage frame 5 is provided with a blanking plate, when the material in the storage funnel 7 is less, the material can be diverted into the storage funnel 7 through the blanking plate. When the dust-proof covers 37 move, they will drive the push frames 51 to move towards each other. When the push frames 51 move, they will squeeze the limit springs 52, thereby limiting the push frames 51 and preventing the surface of the push frames 51 from contacting the surface of the workbench 1. When the push frames 51 move, they will squeeze the elastic frames 53. When the elastic frames 53 are squeezed, the middle part will bend.When the elastic frame 53 bends, it will push the scraper 54 to move on the surface of the filter plate 6 in the direction of approaching each other, so as to concentrate the burrs on the surface of the filter plate 6. When the scraper 54 moves, it will drive the curved plate 55 to move in the direction of approaching each other. When the curved plate 55 moves, it will squeeze the driven plate 57. When the driven plate 57 is squeezed, it will push the cleaning plate 56 to slide on the inner wall of the moving groove in the direction of approaching each other, and clean the burrs on the surface of the filter plate 6. At the same time, when the scraper 54 moves, it will contract the cleaning plate 56 in the direction of approaching each other. When the cleaning plate 56 moves, it will squeeze the elastic plate 58. When the elastic plate 58 is squeezed, the middle part will bend downward. When the elastic plate 58 bends, it will push the expansion rod 59 downward and expand in the direction of moving away from each other. When the expansion rod 59 moves, it will push the opening and closing door 60 downward and expand in the direction of moving away from each other, so that the opening and closing door 60 is opened, and the burrs concentrated by the cleaning plate 56 and the scraper 54 are cleaned into the interior of the storage box 61.
