Description

Technical Field

[0001] The present invention relates to the technical field of grinding for steel structure processing, in particular to a grinding device for steel structure processing. Background Art

[0002] In the field of steel structure processing, grinding, as a key process, plays a vital role in improving the surface quality of steel structures and ensuring subsequent processing and performance. Early steel structure grinding mainly relied on manual handheld grinding tools. This method is not only extremely labor-intensive, but also the grinding quality is heavily dependent on the workers' experience and technical level, making it difficult to ensure the consistency and efficiency of grinding. With the development of industrial automation, mechanical grinding equipment has gradually emerged, from simple handheld electric grinders to early fixed grinding equipment, which has improved grinding efficiency and reduced labor intensity to a certain extent.

[0003] However, due to limitations in design concepts and technical levels, these devices have many deficiencies in terms of functional integration, adjustment flexibility, and degree of automation, making it difficult to meet the growing demand for diversified processing of steel structures. For example, when grinding H-shaped steel structures, I-beams, C-channel steel structures, and other channel steel structures, the grinding wheel of the grinding device cannot extend into the rusty side grooves of the steel structure, resulting in the inability to grind the rust in the side grooves, affecting the structural strength of the steel structure in subsequent use. At the same time, this grinding operation is time-consuming and inefficient. In addition, traditional steel structure grinding equipment lacks an effective automated coordination mechanism in the transportation and grinding links. In actual operation, operators are required to frequently move and adjust the position of the workpiece, which not only consumes a lot of manpower and time, but also increases the risk of human error. Therefore, the above problems need to be improved and resolved. Summary of the Invention

[0052] Working Principle: In this embodiment, the present invention also proposes a method for using a grinding device for steel structure processing, comprising the following steps:

[0053] Step 1: First, electrically connect the various electrical components of the device to the external control device through wires. Then, according to the thickness of the H-shaped steel structure to be polished, adjust the downward pressure height and downward pressure of the conveying pressure roller 6 through the pressure component (adjust the lowering height of the adjusting screw 41 on the guide tube by adjusting the nut 42, and adjust the elastic coefficient of the spring 43 between the adjusting screw 41 and the guide tube by the supporting nut). After completing the adjustment of the height and downward pressure of the conveying pressure roller 6, start the electric push cylinder 11 to drive the drive base 12 to move up and down according to the thickness of the steel structure;

[0054] The second step is to adjust the spacing of the two third rotating shafts 19 on the transmission box 18 according to the width of the steel structure to be polished, and the bidirectional screw rod 31 is driven to rotate by starting the driving motor 39. The rotation of the bidirectional screw rod 31 can drive the adjusting ring seat 30 fixed to the connecting block 32 to move, so that the spacing of the two adjusting ring seats 30 can be adjusted. When the spacing of the adjusting ring seat 30 is adjusted, the spacing between the third rotating shafts 19 can also be adjusted; thereby, the spacing of the two side grinding wire rollers 20 on the same transmission box 18 can be adjusted, so that the adjustment groove can be adapted to steel structures of different widths, so that the brush wire of the side grinding wire roller 20 can extend into the side groove of the H-shaped steel structure. After the spacing of the third rotating shaft 19 is adjusted, the electric push rod 38 is started to drive the tensioning seat 36 to move, and the transmission belt 35 between the two push belt rollers 37 of the transversely moving tensioning seat 36 is tightened or prevented from loosening, so as to improve the transmission stability between the two third rotating shafts 19 through the transmission belt 35;

[0055] Step three, then start the two conveyors 3 to drive the conveyor belts to rotate in the same direction, and then place the steel structure to be polished horizontally on the top of the conveyor 3 on one side of the frame 1, and then, under the action of the conveyor 3 and the conveying pressure roller 6, the steel structure to be polished can be automatically transported to the other side; this is achieved by starting the transmission motor 44 to drive one of the third rotating shafts 19 to rotate, and the rotation of the third rotating shaft 19 drives the side grinding wire roller 20 to rotate, and then starts the hydraulic jacking cylinder 23 to drive the lifting plate 16 and the H-shaped bracket 17 and the transmission box 18 to perform reciprocating lifting operations. The lifting plate 16 that is lifted and lowered reciprocatingly can drive the reciprocating seat 7 on the two L-shaped beams under the action of the reciprocating push rod 28. 2 performs a reciprocating forward and backward sliding operation; by driving another third rotating shaft 19 to rotate by the transmission assembly, it is convenient for the steel structure to be polished to perform a preliminary polishing operation on the side grooves and side edges on the front and rear end surfaces of the steel structure from the two side polishing wire rollers 20 on the left side of the frame 1. The reciprocating lifting transmission box 18 can drive the third rotating shaft 19 and the side polishing wire rollers 20 to perform the polishing operation when lifting, which is convenient for improving the polishing operation for steel structures with different notch heights, and can achieve burr-free polishing operation on the edges of the steel structure, avoiding the situation that burrs are easily generated when polishing at the transmission fixed point, and facilitating the direct drop of the slag polished from the side groove of the steel structure during the reciprocating lifting process;

[0056] Step 4: After the steel structure is preliminarily polished by a pair of side polishing wire rollers 20 on the left, the first rotating shaft 8 and the lower polishing wire roller 9 are rotated by the started high-speed motor, and the two second rotating shafts 13 are rotated in the opposite direction by the cooperation of the servo motor 15 and the transmission gear, and then the two second rotating shafts 13 are driven to drive the upper polishing wire roller 14 to rotate. When the steel structure passes through the cooperation of the conveyor 3 and the conveying pressure roller 6 on one side, the steel structure with the preliminary side polishing of the mechanism is continued to be conveyed to the other conveyor 3. When the steel structure passes between the lower polishing wire roller 9 and the upper polishing wire roller 14, the steel structure is When the reciprocating seat 7 is moved back and forth, the high-speed rotating lower grinding wire roller 9 and the upper grinding wire roller 14 can be driven to perform a front-to-back pulling end surface grinding operation on the steel structure, thereby improving the applicability of the upper grinding wire roller 14 and the lower grinding wire roller 9 for grinding steel structures of different widths. Furthermore, the back-and-forth reciprocating pulling rotation grinding of the lower grinding wire roller 9 and the upper grinding wire roller 14 facilitates the rust residue ground off from the top surface of the steel structure. Furthermore, the uniformity of the grinding of the upper and lower end surfaces of the steel structure and the smoothness after grinding can be improved.

[0057] Step 5: The reciprocating seat 7 moves back and forth, driving the telescopic air pump 26 to continuously pump air into the air pump seat 24. The high-pressure airflow inside the air pump seat 24 passes through the air pipe 25 and the Z-shaped memory metal tube, and is blown onto the steel structure from the flat blowing port of the eccentric dust blowing nozzle 27 (the blowing angle and height of the eccentric dust blowing nozzle 27 can be adjusted according to the size of the steel structure through the arrangement of the Z-shaped memory metal tube), so as to further remove the rust residue polished from the surface of the steel structure.

[0058] Step six, after completing the double grinding of the upper and lower end faces of the steel structure, the steel structure will move to the other pair of side grinding wire rollers 20. The side grinding wire rollers 20 that rotate at high speed and reciprocate and lift can realize the final grinding operation of the front and rear side grooves of the steel structure, effectively realizing the cleanliness and convenience of the grinding operation of the side grooves of the steel structure, and realizing the purpose of continuous grinding operation of the steel structure, thereby improving the work efficiency of surface grinding processing of batches of steel structures. Finally, the polished steel structure will be automatically transported from this device under the action of another conveyor 3.
