Description

Technical Field

[0001] The invention belongs to the technical field of steel processing equipment, and in particular relates to a shot blasting device for steel processing. Background Art

[0002] Steel is a metal material based on iron and containing a certain amount of carbon and other elements. Steel is one of the most common engineering materials in industry and construction. It is widely used in structural parts, mechanical parts, tools, transportation and other fields. The performance of steel depends on its chemical composition, manufacturing process and subsequent heat treatment process. Steel is divided into profiles and pipes. Profiles are long strips of steel with irregular cross-sectional shapes, including angle steel, channel steel, I-beam, H-beam, T-beam and C-beam; pipes are hollow round or other shaped steel, with the appearance of round tubes, square tubes or rectangular tubes, etc. Steel shot blasting is a common metal surface treatment process, which mainly uses a high-speed rotating shot blasting machine to hit the steel surface at high speed, so as to remove surface dirt, rust and oxide layer, and also can make certain plastic deformation on the steel surface to enhance its corrosion resistance or adhesion.

[0003] In the existing shot blasting process for round tube steel, the steel is usually placed on a feeding roller, and the outer wall is shot blasted when passing through a shot blasting device. However, in this process, manual loading and unloading are usually performed, which is inefficient, and the existing shot blasting device cannot simultaneously shot blast the outer and inner walls of the steel. After each shot blasting of the outer wall of the steel, it is necessary to feed again to shot blast the inner wall, thereby increasing the processing steps and greatly reducing the shot blasting efficiency. Summary of the invention

[0006] Furthermore, the feeding mechanism includes a feeding rack, a baffle is fixedly connected to the front end of the feeding rack, a rectangular groove is opened at the top front end of the feeding rack, a mounting seat is fixedly connected to one side of the top rear end of the support frame, a hydraulic cylinder is fixedly installed on the mounting seat, the top end of the hydraulic cylinder piston is fixedly connected to a top plate, mounting grooves are opened on both sides of the rear end of the top plate, limiting grooves are provided in the two mounting grooves, top blocks are slidably connected to both sides of the top plate, and multiple fixing screws are fixedly connected to the inner end surfaces of the two top blocks, and the multiple fixing screws respectively penetrate the corresponding limiting grooves, and nuts are threaded on the two fixing screws.

[0007] Through the above technical scheme, the staff first places the round tube steel that needs shot blasting on the loading rack, and the loading rack automatically rolls toward the baffle by gravity, and starts the hydraulic cylinder.

[0034] The working principle of this embodiment is as follows: the staff first places the round tube steel 13 that needs to be shot blasted on the loading rack 101, and the loading rack 101 automatically rolls toward the baffle 102 by gravity, and the hydraulic cylinder 105 is started. The hydraulic cylinder 105 pushes the top plate 106 through the piston, and pushes the two top blocks 109 at the same time. When the round tube steel 13 is on the top of the top plate 106, it is pushed to the top of the baffle 102. Since the top of the top plate 106 and the top of the baffle 102 are both inclined surfaces, the round tube steel 13 automatically rolls onto the V-shaped rack 403. At this time, the round tube steel 13 is supported by two driven wheels 404 and two driving wheels 407; When shot blasting is required, the second motor 415 is started, and the third gear 416 is driven to rotate through the output shaft, and the slide plate 401 is driven to move with the cooperation of the rack 31, thereby driving the round tube steel 13 to move; When one end of the outer wall of the round tube steel 13 is moved into the shot blasting box 5 through the feeding mechanism 4, the first pump body 702 is started, and the shot in the storage box 8 is extracted through the first connecting pipe 704, and sprayed toward the outer wall of the round tube steel 13 through the first nozzle 703. At the same time, the first motor 410 is started, and the second gear 411 is driven to rotate through the output shaft, thereby driving the first gear 408 to rotate, thereby driving the connected rotating shaft 406 to rotate, and then driving the driving wheel 407 to rotate. Similarly, the other driving wheel 407 rotates to drive the round tube steel 13 to rotate, so as to realize shot blasting on the outer wall of the round tube steel 13, and at the same time, the waste box 9 collects the shot after shot blasting; At the same time, the round tube steel 13 is moved by the slide plate 401, and the entire second pump body 1103 is close to one end of the inner wall of the round tube steel 13. At this time, the second pump body 1103 is started, and the pellets in the storage box 8 are extracted through the second connecting pipe 1105, the fixed pipe 1101 and the third connecting pipe 1106, and are sprayed toward the inner wall of the round tube steel 13 through the second nozzle 1104.

After flipping to a certain angle, the processed round tube steel 13 rolls to the receiving box 12 by gravity. The staff collects the shot blasted round tube steel 13 through the receiving box 12. At the same time, the two cylinders 413 automatically reset to transport the next round tube steel 13; When it is necessary to shot blast round tube steel materials 13 of different diameters, the feeding mechanism 1 and the lifting mechanism 10 need to be adjusted. When adjusting the top plate 106, the multiple nuts 111 are loosened, and the two top blocks 109 are slid to the specified position, and then the multiple nuts 111 are threadedly connected with the corresponding fixing screws 110 to fix the two top blocks 109. When pushing the round tube steel material 13 with a larger diameter, when the top plate 106 is lifted up, the two top blocks 109 are driven to lift up the round tube steel material 13; When the height of the second shot blasting mechanism 11 needs to be adjusted, the hand wheel 1010 is turned to drive the connected worm 1008 to rotate, and the other worm 1008 is driven to rotate through the connecting rod 1009, thereby driving the two worm wheels 1007 to rotate, thereby driving the connected threaded sleeve 1006 to rotate, and under the action of multiple limit rods 1004, the two threaded rods 1002 are driven to move up and down, thereby driving the pipe rack 1003 to move up and down, so as to achieve the lifting and lowering adjustment of the second shot blasting mechanism 11. When the larger diameter round tube steel 13 is on the two V-shaped racks 403, the center will shift upward. At this time, the two pipe racks 1003 can be adjusted upward so that the second pump body 1103 is close to the center of the larger diameter round tube steel 13.
