Description

Technical Field

[0001] The present invention relates to the technical field of H-shaped steel production equipment, and in particular to a steel section turning mechanism. Background Art

[0002] Steel structures (such as H-beams, T-beams, and I-beams) are widely used in manufacturing fields such as military, shipbuilding, industry, construction, bridges, tunnels, and breakwaters. Steel processing is primarily done by welding and hot rolling. Welding is widely used due to its flexibility in cross-section and thickness. The steel welding process primarily involves welding the web to one wing to form a T-beam. The T-beam is then flipped over and welded to the other wing.

[0003] At present, the existing steel section turning mechanism, such as the Chinese patent with publication number CN210504546U, discloses an automatic turning and material collection and docking device for steel section, including a steel section avoidance mouth arranged on a turning turntable, and a steel section docking channel located between the mouth top of the steel section avoidance mouth and the outer peripheral surface of the turning turntable, wherein a material collection and docking support is slidably installed on the turning turntable at the steel section avoidance mouth along the docking direction, and the material collection and docking support includes a mouth bottom material collection state and a mouth top docking state, and a material collection and docking driving device is provided between the material collection and docking support and the turning turntable; a material collection and docking device is provided on the material collection and docking support, and a material collection and docking device is provided on the material collection and docking support, and the material collection and docking support is provided with a material collection and clamping device, which can clamp the steel section in the mouth bottom material collection state, so as to cooperate with the turning turntable to complete the automatic turning work, but the structure of the above device is complicated, the positioning effect of the steel section is poor, and the efficiency is low when actually used.

[0004] How to quickly and stably flip the T-shaped steel during the H-shaped steel production process, and automatically position the T-shaped steel and the wing plate to ensure the alignment effect has become a technical problem that needs to be broken through.

[0018] According to the section steel turning mechanism of the present invention, one end of the sliding plate close to the wing plate on both sides of each conveyor is rotatably connected to a plurality of guide wheels.

[0019] The purpose of the present invention is to provide a steel section flipping mechanism, including a moving part, a moving part and a clamping assembly and other structures that cooperate with each other, which can quickly and stably flip the T-section steel during the production process of the H-section steel, saving operation time; the positioning block and the stop block limit the conveying distance of the T-section steel and the wing plate to be welded, and the sliding plate is used to center and limit the T-section steel and the wing plate to be welded, and automatically position the T-section steel and the wing plate to ensure the alignment effect.

[0024] See also Figures 1 to 4 The present invention provides a steel turning mechanism, including a symmetrically arranged base 1, a gap being provided between the two bases 1, a moving part 2 being slidably provided on each base 1 (a slide rail being provided on each base 1, and the moving part 2 being slidably connected to the slide rail), a first telescopic part 11 being provided on each base 1, an output end of the first telescopic part 11 being connected to the interior of the moving part 2, the first telescopic part 11 being able to drive the moving part 2 to move horizontally, a rotating frame 21 being rotatably connected to each moving part 2, a first driving part 211 being provided on each moving part 2, an output shaft of the first driving part 211 being connected to the rotating frame 21, the first driving part 211 being able to drive the rotating frame 21 to rotate, a movable moving bar 22 being provided in the rotating frame 21, and a second The output ends of the telescopic member 221 and the second telescopic member 221 are both inserted into the interior of the rotating frame 21 to connect to the moving bar 22. The moving bar 22 is slidably connected to the interior of the rotating frame 21. The second telescopic member 221 can drive the moving bar 22 to move. A rotating bar 23 rotatably connected to the moving bar 22 is provided inside the rotating frame 21 on one side of the moving bar 22. A driver is provided inside the moving bar 22. The output end of the driver is connected to the rotating bar 23. The driver can drive the rotating bar 23 to rotate; the T-shaped steel 8 is fixed on the rotating bar 23. When the steel needs to be flipped 180°, the driver is used to drive the rotating bar 23 to rotate 90°, and then the first driving member 211 is used to drive the rotating frame 21 to rotate 90°. Finally, the moving bar 22 is used to adjust the height of the rotating bar 23 (see Figure 4 ).

[0025] See also Figures 1 to 7 The rotating bar 23 is symmetrically provided with a clamping assembly 3 for fixing the T-shaped steel 8. The clamping assembly 3 includes a fixed plate 31 connected to the rotating bar 23. A rotatable driving rod 33 is penetrated on the fixed plate 31. The end of the fixed plate 31 away from the center of symmetry is connected to the second driving member 331. The output shaft of the second driving member 331 passes through the fixed plate 31 to connect the driving rod 33. The second driving member 331 can drive the driving rod 33 to rotate. The side of the driving rod 33 close to the center of symmetry is threadedly connected to a movable block 32. The movable block 32 and the fixed plate 31 are symmetrically penetrated with a limit plate 33. When the driving rod 33 rotates, the movable block 32 cannot rotate with the driving rod 33 under the restriction of the limit plate 321 and can only move horizontally; the end of the movable block 32 close to the symmetrical center is elastically connected to the clamping block 34 (the end of the movable block 32 close to the clamping block 34 is inserted into the clamping block 34, and the movable block 32 inside the clamping block 34 is symmetrically provided with an insert block, and the clamping block 34 is provided with a slot that matches the insert block, and the insert blocks are slidably set in the slot, and an elastic member 6 is provided between the insert block and the slot), and the end of the clamping block 34 close to the rotating bar 23 is elastically connected to the clamping block The rod 35 (the connection between the clamping rod 35 and the clamping block 34 is the same as the connection between the clamping block 34 and the movable block 32, and its specific connection structure and working principle are not repeated here), and there are mutually matching inclined surfaces between the movable block 32 and the clamping rod 35; when the wing plate 81 on the T-shaped steel 8 passes under the clamping rod 35, the web of the T-shaped steel 8 passes between the two clamping assemblies 3 located on the same rotating bar 23, and the second driving member 331 is turned on. The second driving member 331 drives the driving rod 33 to rotate, and the movable block 32 drives the clamping block 34 to move horizontally. At this time, the relative position between the movable block 32 and the clamping block 34 will not change (according to actual conditions, the elastic force of the elastic member 6 at the movable block 32 and the clamping block 34 is reasonably selected). After the clamping block 34 abuts the web of the T-shaped steel 8, as the movable block 32 continues to move, the relative position between the movable block 32 and the clamping block 34 changes. The movable block 32 pushes the clamping rod 35, causing the clamping rod 35 to move toward the side close to the wing plate 81 on the T-shaped steel 8 until the clamping rod 35 clamps the wing plate 81 on the T-shaped steel 8. At this time, the clamping block 34 has already clamped the web of the T-shaped steel 8.

[0026] See also Figures 1 to 8 Preferably, one end of the clamping rod 35 close to the rotating bar 23 is connected to the anti-slip sheet 351 to increase the friction between the clamping rod 35 and the T-shaped steel 8.

[0027] See also Figures 1 to 3A conveyor 4 is symmetrically arranged between the two moving parts 2. The conveyor 4 is a roller conveyor that can convey T-shaped steel 8 and the wing plate 81 to be welded (the structure of the conveyor 4 is the same as the existing technology, which is a mature existing technology in this field. Its specific structure and working principle are not repeated here). The conveying direction of the conveyor 4 is perpendicular to the movable direction of the moving part 2. A fixed seat 5 is provided under the conveyor 4. The fixed seats 5 on both sides of each conveyor 4 are symmetrically slidably provided with sliding plates 51. The sliding plates 51 are all "L"-shaped structures. The fixed seats 5 are provided with avoidance grooves that allow the sliding plates 51 to move. A rotatable The third driving member 52 is provided on the outside of the rotating rod and the fixed seat 5. The output end of the third driving member 52 is inserted into the fixed seat 5 to connect the rotating rod. The third driving member 52 can drive the rotating rod to rotate. The sliding plates 51 are all threadedly connected to the rotating rod, and the internal threads of the two sliding plates 51 on both sides of each conveyor 4 are in opposite directions (the external threads of the rotating rod and the rotating rod are also in opposite directions); when the third driving member 52 is turned on, the third driving member 52 drives the rotating rod to rotate, and the sliding plate 51 cannot rotate with the rotating rod. The sliding plates 51 on both sides of each conveyor 4 move toward each other until the wing plate 81 on the T-shaped steel 8 and the two ends of the wing plate 81 to be welded are clamped.

[0028] See also Figures 1 to 8 Preferably, the sliding plates 51 on both sides of each conveyor 4 are rotatably connected to a plurality of guide wheels 511 at one end close to the wing plate 81, so that the sliding plates 51 can clamp the wing plate 81 without affecting the movement of the wing plate 81.

[0029] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 8The locating seat 71 of one base 1 is symmetrically provided with a positioning seat 7 on the side away from the conveyor 4, and each positioning seat 7 is opposite to a conveyor 4. A positioning block 71 is provided on the positioning seat 7 on the side of the conveyor 4 near the conveyor 4 for conveying the T-shaped steel 8. The positioning block 71 can block the T-shaped steel 8 and position the T-shaped steel 8 before flipping and moving the T-shaped steel 8. The positioning seat 7 on the side of the conveyor 4 near the conveyor 4 for conveying the wing plate 81 to be welded is elastically connected with a stopper 72 (the connection method between the stopper 72 and the positioning seat 7 is the same as the connection method between the clamping block 34 and the movable block 32. Its specific connection structure and working principle are not repeated here). The stopper 72 is an "L"-shaped plate structure. A avoidance hole 721 is provided on the stopper 72 to allow the wing plate 81 to be welded and the web of the T-shaped steel 8 to pass through after alignment. Before the wing plate 81 to be welded is aligned with the T-shaped steel 8, the stopper 72 can position the wing plate 81 to be welded; after the moving part 2 flips the T-shaped steel 8, The T-shaped steel 8 moves to the top of the wing plate 81 to be welded (the wing plate 81 on the T-shaped steel 8 is located above, and the web on the T-shaped steel 8 is located below), and the moving part 2 drives the T-shaped steel 8 to descend. When the wing plate 81 on the T-shaped steel 8 contacts the stopper 72, the wing plate 81 on the T-shaped steel 8 presses down the stopper 72, so that part of the stopper 72 retracts into the positioning seat 7. When the T-shaped steel 8 is completely placed on the wing plate 81 to be welded (that is, the T-shaped steel 8 and the wing plate 81 to be welded are aligned), the T-shaped steel 8 is completely placed on the wing plate 81 to be welded (that is, the T-shaped steel 8 and the wing plate 81 to be welded are aligned). When the T-shaped steel 8 and the wing plate 81 to be welded are aligned, the avoidance hole 721 of the stopper 72 is exactly in line with the wing plate 81 to be welded and the T-shaped steel 8. At this time, the clamping assembly 3 releases the T-shaped steel 8, and the conveyor 4 is used to transport the aligned T-shaped steel 8 and the wing plate 81 to be welded. The T-shaped steel 8 and the wing plate 81 to be welded can smoothly pass through the avoidance hole 721 and proceed to the next welding process. When the T-shaped steel 8 is out of contact with the stopper 72, the stopper 72 returns to its initial position under the action of the elastic member 6 at the stopper 72.

[0030] See also Figures 1 to 8 Preferably, the elastic member 6 is a spring to provide return power.

[0031] See also Figures 1 to 8 Preferably, the first telescopic member 11 and the second telescopic member 221 are both cylinders, and the first driving member 211, the driver, the second driving member 331 and the third driving member 52 are all rotary motors.

[0032] See also Figures 1 to 8, the conveying structure is used to convey the T-shaped steel 8 and the wing plate 81 to be welded to the two conveyors 4 respectively, the positioning block 71 and the stop block 72 limit the conveying distance of the T-shaped steel 8 and the wing plate 81 to be welded, and the sliding plate 51 is used to center and limit the T-shaped steel 8 and the wing plate 81 to be welded, and then the second driving member 331 is turned on, and the second driving member 331 drives the driving rod 33 to rotate, and the movable block 32 drives the clamping block 34 to move horizontally. When the clamping block 34 abuts the web of the T-shaped steel 8, as the movable block 32 continues to move, the relative position between the movable block 32 and the clamping block 34 changes, and the movable block 32 pushes the clamping rod 35, so that the clamping rod 35 moves to the side close to the wing plate 81 on the T-shaped steel 8 until the clamping rod 331 is turned on. 5. Clamp the flange 81 on the T-shaped steel 8. At this time, the clamping block 34 has already clamped the web of the T-shaped steel 8. After turning the T-shaped steel 8 over using the structure on the movable member 2, the T-shaped steel 8 is moved to directly above the flange 81 to be welded. The movable bar 22 drives the T-shaped steel 8 downward. When the flange 81 on the T-shaped steel 8 contacts the stopper 72, the flange 81 on the T-shaped steel 8 presses down the stopper 72, causing the stopper 72 to partially retract into the positioning seat 7. When the T-shaped steel 8 is completely placed on the flange 81 to be welded, the avoidance hole 721 of the stopper 72 is exactly aligned with the flange 81 to be welded and the T-shaped steel 8. At this time, the clamping assembly 3 releases the T-shaped steel 8. The conveyor 4 transports the aligned T-shaped steel 8 and the flange 81 to be welded to the next welding process.

[0033] The present invention provides a steel section flipping mechanism, including a moving part, a moving part and a clamping assembly and other structures that cooperate with each other, which can quickly and stably flip the T-section steel during the production process of the H-section steel, saving operation time; the positioning block and the stop block limit the conveying distance of the T-section steel and the wing plate to be welded, and the sliding plate is used to center and limit the T-section steel and the wing plate to be welded, and automatically position the T-section steel and the wing plate to ensure the alignment effect. In summary, the beneficial effects of the present invention are: it can quickly and stably flip the T-section steel during the production process of the H-section steel, and can automatically position the T-section steel and the wing plate to ensure the alignment effect.
