Description

Technical Field

[0001] The invention relates to the technical field of steel structure processing, in particular to a shot blasting machine for welding seams of building steel structure parts. Background Art

[0002] Shot blasting of welds of building steel structures is a common surface treatment process, which is mainly used to improve the surface quality of welds and their surroundings. After shot blasting, the welds of steel structures can remove welding defects, ensure the quality of welds, and improve adhesion to facilitate subsequent anti-rust paint coating, as well as improve durability and stress relief. Traditional shot blasting of welds of building steel structures is mostly to automatically transfer large building steel structures to the hood of the shot blasting machine, and use the shot blasting mechanism to spray steel balls at high speed for shot blasting. Among them, large building steel structures are inconvenient to flip over in the hood of the shot blasting machine, so it takes a long time to spray steel balls to process the welds in the narrow space of the steel structure, which is inefficient and increases the cost of processing. Secondly, the weld scraps and other scraps generated during the processing will be mixed with the steel balls, resulting in the inability to effectively recycle the steel balls after shot blasting, which will increase the use cost of the entire shot blasting machine.

[0040] Working principle: The welded long building steel structure is placed on a plurality of guide rollers 52 in the feeding mechanism 5 at one side of the shot blasting mechanism 2. The long building steel structure is driven to perform automatic translational driving by controlling the use of the plurality of guide rollers 52. The long building steel structure passes through the guide groove 701 in the second transfer member 64 and contacts with the two guide longitudinal rollers 72 and the two guide transverse rollers 73. The long building steel structure is supported and transmitted by rollers through the two guide longitudinal rollers 72 and the two guide transverse rollers 73. After the long steel structure is transmitted, it passes through the material guide groove 701 in the first transfer member 7 and contacts the two material guide longitudinal rollers 72 and the two material guide transverse rollers 73.

Since the first gear 742 and the first gear ring 761 are meshed and connected, and the second gear 752 and the second gear ring 762 are meshed and connected, the first gear ring 761 drives the first gear 742 to rotate on its own, and the second gear ring 762 drives the second gear 752 to rotate on its own, and cooperates with the transmission of the first sprocket transmission group 741 and the transmission of the second sprocket transmission group 751 to drive the two material guide longitudinal rollers 72 and the two material guide transverse rollers 73 to rotate synchronously, thereby driving the long building steel structure between the two material guide longitudinal rollers 72 and the two material guide transverse rollers 73 to automatically transmit, and synchronously control the long building steel structure to rotate; When the long building steel structure rotates, the transfer outer frame 71 in the second transfer member 64 also rotates, and the two material guide longitudinal rollers 72 and the two material guide transverse rollers 73 in the second transfer member 64 also rotate synchronously, thereby assisting in driving the long building steel structure in the second transfer member 64 to automatically transfer and rotate, thereby improving the stability of the feeding rotation of the long building steel structure; Cooperate with the shot blasting mechanism 25 to quickly blast the rotating long building steel structure parts with high-speed steel balls, and quickly blast the welds in the narrow space of the steel structure parts, which improves the efficiency of shot blasting of the welds of the building steel structure; The weld scraps and other scraps generated during the shot blasting process will be mixed with the steel balls and introduced into the end of the auxiliary screen outer frame 31 away from the bead discharge frame 36 through the bead guide inclined plate 221 on the material gathering frame 22, and automatically introduced into one end of the screen cylinder 32 through the inlet slot; When the transfer outer frame 71 rotates, the meshing connection of the third sprocket 9, the fourth sprocket 91 and the third chain 92 drives the guide shaft 33 to rotate synchronously, and the spoiler frame 35 is driven to rotate by driving the guide shaft 33 to rotate. At the same time, the spiral auger 34 rotates, driving the steel balls and waste chips mixture introduced into one end of the screen cylinder 32 to move toward one end of the bead discharge frame 36. The spoiler frame 35 disturbs the steel balls and waste chips mixture introduced into one end of the screen cylinder 32, and the waste chips can be gradually discharged through the multiple chip discharge grooves 301 and discharged through the waste discharge frame 311, so that the steel balls and waste chips mixture are automatically screened, and the screened steel balls are retained in the screen cylinder 32, and the screened steel balls are automatically introduced into the bead discharge inclined tube 361 through the bead discharge frame 36, so as to facilitate the direct secondary recovery of the steel balls after subsequent screening; Among them, the steel balls for the shot blasting machine are transported by opening the feeding device 4. At the same time, the screened steel balls are transmitted to the discharge main pipe 42, and introduced into the corresponding shot blasting mechanism 25 through the discharge branch pipe 43 and multiple ball inlet branch pipes 24 for use.
