Description

Technical Field

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

[0002] Steel structures (such as H-beams, T-beams, I-beams, etc.) have been widely used in manufacturing fields such as military, shipbuilding, industry, construction, bridges, tunnels, and breakwaters. The processing of section steel is mainly divided into two methods: welding and hot rolling. Among them, the welding method is widely used because of the flexible cross-section and thickness. The section steel welding process is mainly to first weld the web on a wing plate to form a T-beam, and then flip the T-beam and weld the T-beam with another wing plate.

[0003] At present, the existing section steel flipping mechanism, such as the Chinese patent with the publication number CN210504546U, discloses a section steel automatic flipping and feeding docking device, which includes a section steel avoidance opening provided on a flipping turntable, and a section steel docking channel located between the top of the section steel avoidance opening and the outer peripheral surface of the flipping turntable. A feeding docking support is slidably installed along the docking direction at the section steel avoidance opening on the flipping turntable. The feeding docking support includes a bottom feeding state and a top docking state. A feeding docking driving device is provided between the feeding docking support and the flipping turntable; a feeding clamping device is provided on the feeding docking support. The feeding docking support is provided with a feeding clamping device. The feeding clamping device can clamp the section steel in the bottom feeding state, which is convenient to cooperate with the flipping turntable to complete the automatic flipping work. However, the structure of the above device is complex, the positioning effect on the section steel is poor, and the efficiency is low during actual use.

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

[0005] In summary, the existing technology obviously has inconveniences and defects in actual use, so it is necessary to be improved. Summary of the Invention

[0006] Aiming at the above defects, the purpose of the present invention is to provide a section steel flipping mechanism, which can quickly and stably flip the T-beam during the production process of H-beams, and can automatically position the T-beam and the wing plate to ensure the alignment effect.

[0007] To achieve the above object, the present invention provides a section steel turning mechanism, which includes symmetrically arranged movable members. Rotatable rotating frames are rotatably connected to the movable members. Movable bars are movably arranged in the rotating frames. Rotating bars are rotatably arranged on the movable bars. Clamping assemblies for fixing the T-section steel are symmetrically arranged on the rotating bars. Each clamping assembly includes a fixing plate connected to the rotating bar. Movable blocks that can move horizontally are arranged on one side of the fixing plate close to the symmetric center. Clamping blocks are elastically connected to one ends of the movable blocks close to the symmetric center. Clamping rods are elastically connected to one ends of the clamping blocks close to the rotating bar. Inclined surfaces that cooperate with each other are arranged between the movable blocks and the clamping rods.

[0008] A conveyor for conveying the T-section steel and the wing plates to be welded is symmetrically arranged between the two movable members. Sliding plates that can move towards each other are symmetrically arranged on both sides of each conveyor.

[0009] Let the movable block drive the clamping block to move horizontally. When the clamping block abuts against the web of the T-section steel, as the movable block continues to move, a relative position change occurs between the movable block and the clamping block, and the movable block pushes the clamping rod, causing the clamping rod to move towards the side close to the wing plate on the T-section steel.

[0010] According to the section steel turning mechanism of the present invention, positioning seats that cooperate with the conveyor are symmetrically arranged on one side of one of the movable members away from the conveyor. A positioning block is arranged on the positioning seat on the side of the conveyor close to the T-section steel being conveyed. A stop block is elastically connected to the positioning seat on the side of the conveyor close to the wing plates to be welded.

[0011] According to the section steel turning mechanism of the present invention, an avoidance hole is arranged on the stop block.

[0012] According to the section steel turning mechanism of the present invention, rotatable driving rods are penetrated through the fixing plates. The movable blocks are threadedly connected to the driving rods. Limiting plates are symmetrically penetrated through the movable blocks and the fixing plates.

[0013] According to the section steel turning mechanism of the present invention, one ends of the movable blocks close to the clamping blocks penetrate into the clamping blocks. Insert blocks are symmetrically arranged on the movable blocks inside the clamping blocks. Slots that cooperate with the insert blocks are arranged inside the clamping blocks. The insert blocks are slidably arranged in the slots. Elastic members are arranged between the insert blocks and the slots.

[0014] According to the section steel turning mechanism of the present invention, the elastic member is a spring.

[0015] According to the section steel turning mechanism of the present invention, anti-slip sheets are connected to one ends of the clamping rods close to the rotating bar.

[0016] According to the H-shaped steel flipping mechanism of the present invention, a fixed seat is provided below the conveyor. A rotatable rotating rod is rotatably connected within the fixed seat. The sliding plates are all threadedly connected to the rotating rod, and the internal thread directions of the two sliding plates on both sides of each conveyor are opposite.

[0017] According to the H-shaped steel flipping mechanism of the present invention, the sliding plates are all of an "L" shape structure.

[0018] According to the H-shaped steel flipping mechanism of the present invention, a number of guide wheels are rotatably connected to one end of each sliding plate on both sides of each conveyor close to the wing plate.

[0019] The purpose of the present invention is to provide an H-shaped steel flipping mechanism, including a moving member, and structures such as the moving member and the clamping assembly cooperate with each other. During the production process of H-shaped steel, the T-shaped steel can be quickly and stably flipped, saving operation time. The positioning block and the stop block limit the conveying distance of the T-shaped steel and the wing plate to be welded. The sliding plate is used to center and limit the T-shaped steel and the wing plate to be welded, automatically positioning the T-shaped steel and the wing plate to ensure the alignment effect. In summary, the beneficial effects of the present invention are: during the production process of H-shaped steel, the T-shaped steel can be quickly and stably flipped, and the T-shaped steel and the wing plate can be automatically positioned to ensure the alignment effect.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection, can be a mechanical connection, can be an electrical connection, can be directly connected, or can be indirectly connected through an intermediate medium, and can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] See Figures 1 to 4 , the present invention provides a section steel turning mechanism, including symmetrically arranged bases 1 with a gap between the two bases 1. Moving members 2 are slidably arranged on the bases 1 (slide rails are provided on the bases 1, and the moving members 2 are slidably connected to the slide rails). First telescopic members 11 are provided on the bases 1, and the output ends of the first telescopic members 11 are connected to the interiors of the moving members 2. The first telescopic members 11 can drive the moving members 2 to move horizontally. Rotating frames 21 are rotatably connected to the moving members 2. First driving members 211 are provided on the moving members 2, and the output shafts of the first driving members 211 are connected to the rotating frames 21. The first driving members 211 can drive the rotating frames 21 to rotate. Movable moving bars 22 are provided in the rotating frames 21. Second telescopic members 221 are provided outside the rotating frames 21, and the output ends of the second telescopic members 221 penetrate into the interiors of the rotating frames 21 to be connected to the moving bars 22. The moving bars 22 are slidably connected to the interiors of the rotating frames 21. The second telescopic members 221 can drive the moving bars 22 to move. Rotating bars 23 rotatably connected to the moving bars 22 are provided inside the rotating frames 21 on one side of the moving bars 22. A driver is provided in the moving bars 22, and the output end of the driver is connected to the rotating bars 23. The driver can drive the rotating bars 23 to rotate; the T-shaped section steel 8 is fixed to the rotating bars 23. When it is necessary to turn the section steel 180°, the driver is used to drive the rotating bars 23 to rotate 90°, then the first driving members 211 are used to drive the rotating frames 21 to rotate 90°, and finally the height of the rotating bars 23 is adjusted by the moving bars 22 (see Figure 4 ).

[0025] See Figures 1 to 7 , symmetrically provided on the rotating bar 23 are clamping assemblies 3 for fixing the T-shaped steel 8. Each clamping assembly 3 includes a fixing plate 31 connected to the rotating bar 23. Rotatably arranged on the fixing plate 31 are driving rods 33. Connected to one end of the fixing plate 31 away from the symmetric center are second driving members 331. The output shafts of the second driving members 331 all pass through the fixing plate 31 to connect the driving rods 33. The second driving members 331 can drive the driving rods 33 to rotate. Threadedly connected to one side of the driving rods 33 close to the symmetric center are movable blocks 32. Symmetrically arranged on the movable blocks 32 and the fixing plate 31 are limiting plates 321. When the driving rods 33 rotate, restricted by the limiting plates 321, the movable blocks 32 cannot rotate with the driving rods 33 and can only move horizontally. Elasticly connected to one end of the movable blocks 32 close to the symmetric center are clamping blocks 34 (one end of the movable block 32 close to the clamping block 34 penetrates into the clamping block 34. Symmetrically arranged on the movable block 32 inside the clamping block 34 are insertion blocks. Inside the clamping block 34 are slots cooperating with the insertion blocks. The insertion blocks are all slidably arranged in the slots. Elastic members 6 are arranged between the insertion blocks and the slots). Elasticly connected to one end of the clamping blocks 34 close to the rotating bar 23 are clamping rods 35 (the connection manner between the clamping rods 35 and the clamping blocks 34 is the same as that between the clamping blocks 34 and the movable blocks 32. The specific connection structure and working principle are not elaborated here). There are mutually cooperating inclined surfaces between the movable blocks 32 and the clamping rods 35. When the flange 81 on the T-shaped steel 8 passes under the clamping rods 35, the web of the T-shaped steel 8 passes between two clamping assemblies 3 on the same rotating bar 23. The second driving member 331 is turned on. The second driving member 331 drives the driving rod 33 to rotate. The movable block 32 drives the clamping block 34 to move horizontally. At this time, there will be no relative position change between the movable block 32 and the clamping block 34 (select the elastic force of the elastic member 6 at the movable block 32 and the clamping block 34 reasonably according to the actual situation). When the clamping block 34 abuts against the web of the T-shaped steel 8, with the continuous movement of the movable block 32, a relative position change occurs between the movable block 32 and the clamping block 34. The movable block 32 pushes the clamping rod 35, causing the clamping rod 35 to move towards the side close to the flange 81 on the T-shaped steel 8 until the clamping rod 35 clamps 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.

[0026] See Figures 1 to 8 , preferably, connected to one end of the clamping rods 35 close to the rotating bar 23 are anti-slip sheets 351 to increase the friction force between the clamping rods 35 and the T-shaped steel 8.

[0027] See Figures 1 to 3, a conveyor 4 is symmetrically arranged between two moving parts 2. The conveyor 4 is a roller conveyor that can convey T-shaped steel 8 and wing plates 81 to be welded (the structure of the conveyor 4 is the same as that of the prior art, which is a mature prior art in this field, and its specific structure and working principle will not be elaborated here). The conveying direction of the conveyor 4 is perpendicular to the movable direction of the moving part 2. A fixed seat 5 is arranged below the conveyor 4. On the fixed seats 5 on both sides of each conveyor 4, sliding plates 51 are symmetrically and slidably arranged. The sliding plates 51 are all of an "L" shape. Avoidance grooves allowing the sliding plates 51 to move are arranged on the fixed seats 5. A rotatable rotating rod is rotatably connected inside the fixed seat 5. A third driving member 52 is arranged outside the fixed seat 5. The output end of the third driving member 52 penetrates into the fixed seat 5 and is connected to 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 thread directions of the two sliding plates 51 on both sides of each conveyor 4 are opposite (the external thread direction of the rotating rod cooperating with it is also opposite). When the third driving member 52 is turned on, the third driving member 52 drives the rotating rod to rotate. The sliding plates 51 cannot rotate with the rotating rod. The sliding plates 51 on both sides of each conveyor 4 move towards each other until the two ends of the wing plates 81 on the T-shaped steel 8 and the wing plates 81 to be welded are clamped.

[0028] See Figures 1 to 8 , preferably, a plurality of guide wheels 511 are rotatably connected to one end of each sliding plate 51 on both sides of each conveyor 4 close to the wing plate 81, so that the sliding plate 51 can clamp the wing plate 81 and does not affect the movement of the wing plate 81.

[0029] See Figure 1 , Figure 2 , Figure 3 and Figure 8, on one side of one base 1 away from the conveyor 4, positioning seats 7 are symmetrically arranged. Each positioning seat 7 faces one conveyor 4. A positioning block 71 is arranged on the positioning seat 7 on the side of the conveyor 4 close to the conveyed T-shaped steel 8. The positioning block 71 can block the T-shaped steel 8 to position the T-shaped steel 8 before it is flipped and moved. An elastic block 72 is elastically connected to the positioning seat 7 on the side of the conveyor 4 close to the wing plate 81 to be welded (the connection method between the block 72 and the positioning seat 7 is the same as the connection method between the clamping block 34 and the movable block 32. The specific connection structure and working principle are not elaborated here). The block 72 is an "L"-shaped plate structure. An avoidance hole 721 is arranged on the block 72 through which the wing plate 81 to be welded and the web of the T-shaped steel 8 can pass after alignment. Before the wing plate 81 to be welded and the T-shaped steel 8 are aligned, the block 72 can position the wing plate 81 to be welded; after the moving member 2 flips the T-shaped steel 8, it moves the T-shaped steel 8 directly above the wing plate 81 to be welded (at this time, the wing plate 81 on the T-shaped steel 8 is above and the web on the T-shaped steel 8 is below). Then, the moving member 2 drives the T-shaped steel 8 to descend. When the wing plate 81 on the T-shaped steel 8 contacts the block 72, the wing plate 81 on the T-shaped steel 8 presses down the block 72, causing part of the block 72 to retract into the positioning seat 7. When the T-shaped steel 8 is completely placed on the wing plate 81 to be welded (i.e., the T-shaped steel 8 and the wing plate 81 to be welded are aligned), the avoidance hole 721 of the block 72 just faces 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 conveys 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 to perform the next welding process. When the T-shaped steel 8 is separated from the block 72, the block 72 returns to its initial position under the action of the elastic member 6 at the block 72.

[0030] See Figures 1 to 8 , preferably, the elastic member 6 is a spring, providing the return power.

[0031] See Figures 1 to 8 , preferably, the first telescopic member 11 and the second telescopic member 221 are both oil 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 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 two conveyors 4 respectively. The positioning block 71 and the stop block 72 limit the conveying distances of the T-shaped steel 8 and the wing plate 81 to be welded. The sliding plate 51 is used to center and limit the T-shaped steel 8 and the wing plate 81 to be welded. Then, the second driving member 331 is started. 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 against 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 upper wing plate 81 of the T-shaped steel 8 until the clamping rod 35 clamps the upper wing plate 81 of the T-shaped steel 8. At this time, the clamping block 34 has already clamped the web of the T-shaped steel 8. After the T-shaped steel 8 is flipped by the structure on the moving member 2, the T-shaped steel 8 is moved directly above the wing plate 81 to be welded. The moving bar 22 is made to drive the T-shaped steel 8 to descend. When the upper wing plate 81 of the T-shaped steel 8 contacts the stop block 72, the upper wing plate 81 of the T-shaped steel 8 presses down the stop block 72, causing part of the stop block 72 to retract into the positioning seat 7. When the T-shaped steel 8 is completely placed on the wing plate 81 to be welded, the avoidance hole 721 of the stop block 72 just faces the wing plate 81 to be welded and the T-shaped steel 8. At this time, the clamping assembly 3 is made to release the T-shaped steel 8. The conveyor 4 is used to convey the aligned T-shaped steel 8 and the wing plate 81 to be welded, and the next welding process is carried out.

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

[0034] Certainly, the present invention can also have other various embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and deformations according to the present invention, but these corresponding changes and deformations should all fall within the protection scope of the appended claims of the present invention.
