Description

Technical Field

[0001] This invention relates to the field of H-beam steel production technology, specifically to an H-beam steel production process and production line. Background Technology

[0002] During the production of H-beams, the steel plates are first clamped onto a CNC assembly machine by an electromagnetic adsorption robot to precisely position the web and flanges. The H-beams are then spot-welded by an automatic spot-fixing mechanism. Subsequently, the H-beams are conveyed to an automatic welding mechanism via a transmission and guiding mechanism to achieve automatic submerged arc welding. The H-beam production line is based on automation and integration, and achieves efficient production through multi-process collaboration.

[0003] Currently, when H-beams are subjected to automated submerged arc welding in automatic welding mechanisms, granular flux is used to cover the welding area. During the welding process, the flux melts and forms slag, protecting the weld metal from air intrusion. However, after melting, the flux easily forms long strips of welding sand on the weld surface, containing unfused flux or impurities. Workers use iron rods to scrape off the excess welding sand. Since there are welding sand on both sides of the H-beam, workers need to scrape back and forth on both sides of the H-beam, which not only consumes a lot of time and manpower, but also requires manual removal of the welding sand to ensure the consistency and uniformity of the removal effect, thus affecting the quality of the weld. To address this, we propose an H-beam production process and production line. Summary of the Invention

Please refer to 6 to Figure 8The support base 5 is equipped with a guide adsorption mechanism 6, and two sand suction shell assemblies 7 are connected to the guide adsorption mechanism 6. The sand suction shell assembly 7 is used to suck in and crush the welding sand strips. As a supplementary explanation, the guiding adsorption mechanism 6 includes a connecting tube, a hose, a transfer tube, and a vacuum cleaner. There are two connecting tubes, one end of which is connected to two sand suction shell assemblies 7 respectively, and the other end of the connecting tube is connected to the hose. Both ends of the transfer tube are connected to the two hoses. The vacuum cleaner is installed at the bottom of the support base 5, and the input end of the vacuum cleaner is connected to the transfer tube. Furthermore, in this application, the vacuum cleaner is an existing vacuum cleaner that can achieve the function of negative pressure vacuuming. Thus, when the vacuum cleaner is running, the two suction shell assemblies 7 are generated by the transfer pipe, two hoses and two connecting pipes, respectively, so as to achieve the function of vacuuming the welding sand strip.

[0020] The sand suction shell assembly 7 is provided with a cutting and scraping plate 8 on the outside. The cutting and scraping plate 8 is used to cut and scrape off the welding sand strips. It is connected to the sand suction shell assembly 7 in conjunction with the moving mechanism 9. The support base 5 is also provided with a support connection mechanism 10, which is used to connect the two sand suction shell assemblies 7.

[0021] The support connection mechanism 10 includes an adjusting bracket 101, an adjusting component 102, a support block 103, a support shell 104, a moving component 105, and a moving frame 106. There are two adjusting brackets 101, which are fixedly installed at both ends of the top of the support base 5. The adjusting component 102 is set on the adjusting bracket 101 and is used to drive the support block 103 on the adjusting bracket 101. One side of the support shell 104 is fixedly connected to the two support blocks 103. The movable component 105 is mounted on the support shell 104. There are two movable frames 106. The bottom of both movable frames 106 is slidably connected to the support shell 104. The movable component 105 is used to synchronously drive the two movable frames 106. The movable frame 106 is connected to the sand suction shell assembly 7 and the cooperating movable mechanism 9 respectively; Please see Figure 9 and 13 to Figure 19 The sand suction shell assembly 7 includes a sand inlet shell 71, a rotating sleeve 72, a rotating component 73, a baffle plate 74, a pressing block 75, and a telescopic connector 76. The sand inlet shell 71 is fixedly installed on the movable frame 106. The sand inlet shell 71 is composed of a sand inlet end 711 and a cylindrical end 712. A sand inlet 713 is provided at the sand inlet end 711. In this application, one end of the sand inlet 713 of the sand inlet shell 71 is set to fit against the weld of the H-shaped or T-shaped steel. At the same time, it can guide the cut welding sand strip into the interior of the cylindrical end 712. A sand outlet is provided at the cylindrical end 712, and the guiding suction mechanism 6 is connected to the sand outlet. The rotating sleeve 72 is located at the cylindrical end 712, and the opening of the rotating sleeve 72 faces downward. The rotating sleeve 72 passes through the cylindrical end 712 and is rotatably connected to the cylindrical end 712. The rotating component 73 is installed at the bottom of the cylindrical end 712 and is used to drive the rotating sleeve 72. As a supplementary explanation, the rotating component 73 includes a protective shell 731, a rotating motor 732, a first rotating gear 733, and a second rotating gear 734. The protective shell 731 is fixedly installed inside the sand inlet shell 71, and the rotating motor 732 is fixedly installed inside the protective shell 731. The output end of the rotating motor 732 is fixedly connected to the first rotating gear 733, and the first rotating gear 733 is meshed with the second rotating gear 734. The second rotating gear 734 is fixedly sleeved on the outside of the bottom of the rotating sleeve 72. Therefore, when the rotating sleeve 72 is driven, the rotating motor 732 runs, which causes the first rotating gear 733 to drive the second rotating gear 734 to rotate. When the second rotating gear 734 rotates, it synchronously drives the rotating sleeve 72 to rotate relative to the cylindrical end 712. Multiple baffle plates 74 are provided. Multiple baffle plates 74 are fixedly installed on the outside of the rotating sleeve 72, and multiple baffle plates 74 are slidably connected to the inner wall of the cylindrical end 712. At the same time, in this application, multiple baffle plates 74 are provided with multiple through holes to ensure that the inside of the sand shell and the feed inlet are in a negative pressure state. Multiple pressing blocks 75 are provided, and the pressing blocks 75 are disposed between two baffle plates 74. In this application, the pressing blocks 75 are set in the shape of a triangular cone, so as to avoid the granular slag after crushing adhering to the upper surface of the pressing blocks. The rotating sleeve 72 is provided with a moving port 721 corresponding to the position of the telescopic connector 76. The telescopic connector 76 is disposed between the rotating sleeve 72 and the multiple pressing blocks 75.

[0022] The telescopic connector 76 includes a connecting rod 761, a connecting block 762, a guide strip 763, and a supporting rotating component 77. The connecting rod 761 slides through the bottom end of the rotating sleeve 72. Multiple connecting blocks 762 are provided. The connecting blocks 762 slide through the moving opening 721. One end of the connecting block 762 is fixedly connected to the pressing block 75, and the other end of the connecting block 762 is fixedly connected to the connecting rod 761. Two guide bars 763 are provided, and the two guide bars 763 are fixedly installed on the outside of the connecting rod 761. The rotating sleeve 72 is provided with a guide groove corresponding to the position of the guide bar 763. The supporting rotating part 77 is provided below the sand inlet shell 71, and the supporting rotating part 77 is connected to the bottom of the connecting rod 761.

[0023] The rotating support 77 includes a base frame 771, a guide sleeve 772, a guide shaft 773, and a connecting spring 774. The base frame 771 is fixedly installed at the bottom of the sand inlet shell 71, and the guide sleeve 772 is fixedly installed on the base frame 771. The bottom of the connecting rod 761 is slidably connected to the inside of the guide sleeve 772. The guide sleeve 772 is provided with a guide opening 7721. The guide opening 7721 in this application can be referred to the appendix of the specification. Figures 17 to 19 The guide shaft 773 slides through the guide opening 7721, and one end of the guide shaft 773 is fixedly connected to the connecting rod 761. The connecting spring 774 is fixedly installed at the bottom end inside the guide sleeve 772, and the connecting spring 774 is in contact with the connecting rod 761.

[0024] Specific implementation process: In this application, firstly, the two sand inlets 713 of the sand inlet shell 71 are attached to the weld of the H-beam or T-beam. At the same time, the sand inlets 713 are chamfered. At this time, by guiding the adsorption mechanism 6 to run, a negative pressure is generated at the two sand inlets 71, thereby adsorbing the cut welding sand strips at the sand inlets 713 and near the sand inlets 713. At the same time as adsorption, the rotating motor 732 runs, further causing the rotating sleeve 72 to rotate. When the rotating sleeve 72 rotates, the guide groove and the guide strip 763 on the connecting rod 761 further drive the connecting rod 761 to rotate synchronously. That is, at this time, the rotating sleeve 72 rotates the cut welding sand strips between the baffle plates 74 to the sand outlet. At the same time, although the connecting rod 761 rotates synchronously with the rotating sleeve 72, the connecting rod 761 is further moved up and down relative to the rotating sleeve 72 under the limiting action of the guide shaft 773 and the guide port 7721. When the connecting rod 761 moves up and down, the pressure block 75 moves up and down relative to the two baffle plates 74 through the connecting block 762. The pressure block 75 further crushes the cut welding sand strip, so that the crushed granular slag can be sucked into the guiding adsorption mechanism 6, thereby better collecting the granular slag.

[0025] Please see Figures 9 to 13 The cut-off scraping plate 8 is also provided with a cooperating moving mechanism 9. The cooperating moving mechanism 9 includes a side plate 91, a moving frame 92, a synchronizing component 93, a slider 94, a limiting component 95, and an angle positioning component 96. One end of the side plate 91 is fixedly connected to the moving frame 106, the moving frame 92 is slidably connected to the side plate 91, the synchronizing component 93 is provided at the bottom of the side plate 91, and the synchronizing component 93 is connected to the top of the rotating sleeve 72. The slider 94 is slidably connected to the moving frame 92, and the limiting member 95 is disposed between the side plate 91 and the slider 94. The angle positioning member 96 is disposed between the slider 94 and the cutting scraping plate 8.

[0026] The synchronizing component 93 includes a fixed block 931, a reciprocating screw 932, a synchronizing block 933, a first extension rod 934, a first spur bevel gear 935, a second spur bevel gear 936, and a second extension rod 937. There are two fixed blocks 931, which are fixedly installed at the bottom of the side plate 91. The reciprocating screw 932 is rotatably connected between the two fixed blocks 931. The synchronizing block 933 is slidably connected to the bottom of the side plate 91 and is threaded onto the outside of the reciprocating screw 932. The synchronizing block 933 is fixedly connected to the moving frame 92. One end of the first extension rod 934 is fixedly connected to the reciprocating screw 932, and the other end of the first extension rod 934 is fixedly connected to the first spur bevel gear 935. The first straight bevel gear 935 is meshed with the second straight bevel gear 936, and the second extension rod 937 is fixedly installed on the top of the rotating sleeve 72, and the second extension rod 937 is fixedly connected with the second straight bevel gear 936.

[0027] The limiting component 95 includes a limiting shaft 951, which is fixedly installed on the slider 94. The side plate 91 is provided with a limiting groove 911 corresponding to the position of the limiting shaft 951, and the limiting shaft 951 is slidably connected to the limiting groove 911. The two ends of the limiting groove 911 in this application are inclined, thereby guiding the limiting shaft 951.

[0028] The angle positioning component 96 includes a fixed frame 961, a rotating shaft 962, a swing support rod 963, a connecting support rod 964, a connecting shaft 965, and a connecting plate 966. The fixed frame 961 is fixedly installed on the movable frame 92. The rotating shaft 962 passes through the bottom of the fixed frame 961 and is rotatably connected to the fixed frame 961. One end of the rotating shaft 962 is fixedly connected to the cutting and scraping plate 8. One end of the swing support rod 963 is fixedly connected to the rotating shaft 962, and the other end of the swing support rod 963 is rotatably connected to the connecting support rod 964 through a pin. The connecting shaft 965 is fixedly installed on the other end of the connecting support rod 964 and is fixedly connected to the connecting plate 966. The connecting plate 966 is fixedly installed on the slider 94.

[0029] Specific implementation process: In this application, when the rotary motor 732 drives the rotary sleeve 72 to rotate, the rotary sleeve 72 drives the second straight bevel gear 936 to rotate through the second extension rod 937 on it, which in turn causes the first straight bevel gear 935 to drive the reciprocating screw 932 to rotate through the first extension rod 934. When the reciprocating screw 932 rotates, it provides driving force to the synchronizing block 933. At this time, due to the limiting effect of the side plate 91 and the moving frame 92, the synchronizing block 933 further drives the moving frame 92 to move relative to the side plate 91. At this time, the moving frame 92 is located at the end of the side plate 91 away from the sand inlet shell 71, and the bottom of the cutting scraper 8 is in vertical contact with the weld of the H-beam or T-beam, so that the welding sand strip can be cut off quickly. Then, by running the reciprocating screw 932, the moving frame 92 drives the cutting scraper 8 to move quickly along the direction of the sand inlet 713 through the slider 94. In this application, the moving speed of the cutting scraper 8 is greater than the moving speed of the H-beam. As the limiting shaft 951 at the slider 94 moves to the bottom of the other end of the limiting groove 911, the moving frame 92 continues to move toward the sand inlet 713. The limiting shaft 951 then moves upward to limit the inclined position of the limiting groove 911. While the slider 94 moves upward relative to the moving frame 92, the connecting plate 966 and the connecting support rod 964 drive the swing support rod 963 to rotate. While the swing support rod 963 rotates, the rotating shaft 962 drives the cutting scraping plate 8 to rotate synchronously, thereby causing the cutting scraping plate 8 to rotate at a certain angle. At the same time, the cut welding sand strip is further pushed into the sand inlet 713, so that the cut welding sand strip can fully enter the sand inlet shell 71. Subsequently, as the reciprocating screw 932 continues to rotate, the moving frame 92 moves in the opposite direction, and this cycle repeats continuously. As a supplementary explanation, in this application, although a continuous welding abrasive strip is formed at the weld joint during the actual production process, the continuous welding abrasive strip is composed of granular flux and slag. Therefore, if it directly enters the abrasive inlet 713, it will also be subject to the directional force of the abrasive inlet 713, causing the welding abrasive strip to break and fall off. By adopting this cut-off pushing method, it is possible to ensure stable welding of H-beams while fully recovering the welding abrasive strip.

[0030] A production process on an H-beam production line includes the following steps: S1: Weld into T-shaped steel. After splicing a web plate and a flange plate, the first set of welding and straightening integrated machine 1 is used for automated submerged arc welding. After welding, the welding sand strips on both sides of the welded T-shaped steel are cut off and scraped off in sequence by two cutting and scraping plates 8, and the scraped welding sand strips are pushed into the sand suction shell assembly 7. S2: Splicing and spot welding. After the welded T-shaped steel is spliced ​​with another wing plate, it is automatically spot welded at 2 points by the spot welding machine. S3: Flipping, the H-beam initially formed after spot welding is flipped by flipping machine 3 and then pulled and moved by traction mechanism; S4: H-beam welding. After being flipped, the H-beam initially formed is automatically submerged arc welded by the second welding machine. After welding, the welding sand strips on both sides of the welded H-beam are cut off and scraped off in sequence by two cutting scraping plates 8, and the scraped welding sand strips are pushed into the sand suction shell assembly 7.

[0031] Example 2 Please see Figures 6 to 8 Example 2 is a further supplementary description of Example 1. Specifically, the adjusting component 102 includes an adjusting screw and an adjusting block. The adjusting screw is rotatably connected to the adjusting bracket 101, and the adjusting block is fixedly installed on the top of the adjusting screw. The support block 103 is threaded onto the outside of the adjusting screw, and the support block 103 is slidably connected to the adjusting frame. Based on the thickness of the bottom flange of the H-beam, the height of the cutting scraper 8 and the height of the sand suction shell assembly 7 are adjusted. By synchronously rotating the two adjusting blocks, the adjusting screw is rotated. When the adjusting screw rotates, it provides driving force to the support block 103. At this time, the two support blocks 103 drive the support shell 104 on them to adjust the height relative to the vertical direction until the bottom of the cutting scraper 8 in the vertical state contacts the upper surface of the bottom flange of the H-beam.

[0032] Example 3 Please see Figures 6 to 8 Example 3 is a supplementary description of Example 1. Specifically, the moving part 105 includes a bidirectional threaded screw and a handle. The bidirectional threaded screw is rotatably connected inside the support shell 104, and one end of the bidirectional threaded screw extends to the outside of the support shell 104 and is fixedly connected to the handle. Two moving frames 106 are respectively threaded onto the outside of the bidirectional threaded screw. When adjusting the position of the two cutting scraper plates 8 according to the web width of the H-beam, the handle is turned, which in turn causes the double-threaded screw to rotate. As the double-threaded screw rotates, it provides driving force in opposite directions to the two moving frames 106, thereby adjusting the position of the two moving frames 106 relative to the support shell 104, and thus adjusting the position of the two cutting scraper plates 8 so that the two cutting scraper plates 8 can make full contact with the welding sand strip.
