Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figures 1 to 10 The present invention provides a technical solution: an automatic forming device for a box-type prefabricated beam steel bar skeleton, comprising a moving mechanism, a forming mechanism and a clamping mechanism.

[0020] The moving mechanism includes a base 1, a slide rail 2 and a driving rail 3. The slide rail 2 and the driving rail 3 are both arranged on the ground. The base 1 is arranged on the top of the slide rail 2. A first driving mechanism is arranged inside the base 1. The first driving mechanism is connected to the driving rail 3 to drive the base 1 to move. There are two bases 1, and the upper surfaces of the two bases 1 are fixedly connected with a driving end 4 and a driven end 5.

[0021] The clamping mechanism includes a connecting sleeve 6, a plug-in plate 7 and a fixing mechanism. A connecting seat 8 is provided at one end of the driving end 4 and the driven end 5. The connecting sleeve 6 is detachably connected to the connecting seat 8. The plug-in plate 7 is fixedly connected to the surface of the connecting sleeve 6. A plurality of positioning holes 9 for passing threaded steel bars are provided on the surface of the plug-in plate 7. The fixing mechanism is provided on the surface of the plug-in plate 7 to fix the threaded steel bars in the positioning holes 9. A second driving mechanism is provided inside the driving end 4 to drive the connecting seat 8 to rotate.

[0022] The forming mechanism includes a gantry 10, a movable plate 11 and a pressure plate 12. The gantry 10 is arranged on the ground and above the slide rail 2. The movable plate 11 is arranged at the bottom of the gantry 10 in a liftable manner. The pressure plate 12 is arranged at the bottom of the movable plate 11 to press the steel wire. A welding arm 13 is provided at one end of the gantry 10 to weld the steel wire and the threaded steel bar. A grinding mechanism is provided on the other side of the gantry 10 to grind the steel wire.

[0023] The base 1 can slide along the slide rail 2 on the slide rail 2, and the base 1 is driven to move by the first driving mechanism, and the driving end 4 and the driven end 5 move together, so that the steel bar fixed between the two moves at the bottom of the gantry 10, so that the welding arm 13 at the bottom of the gantry 10 welds the steel bar and the steel wire, and the positioning hole 9 opened on the plug-in plate 7 is connected to the end of the steel bar. There are multiple positioning holes 9, and the steel bar can be inserted into the positioning holes 9 at the corresponding positions according to the needs of skeletons of different sizes. The second driving mechanism drives the connecting seat 8 on one side of the driving end 4 to rotate, and during the rotation of the driving end 4, it will drive the driven end 5 at the other end to rotate, so that the entire steel bar frame rotates together, and during the rotation of the driving end 4 And the moving end moves to one side so that the steel wire is wound around the outside of the steel bar frame to form a box beam skeleton. The fixing mechanism fixes the steel bars inserted into the positioning holes 9 to prevent the steel bars from accidentally falling out of the positioning holes 9. The movable plate 11 can move up and down to adapt to frames of different sizes. The pressing plate 12 can guide the steel wire so that the steel wire can fit better on the outside of the steel bar, making it convenient for the welding arm 13 to weld the two together. Before the steel wire enters the gantry 10, it will first pass through a grinding mechanism. The grinding mechanism can rub against the outer wall of the steel bar to remove the oxide layer on the surface of the steel bar, making it more secure during welding. Laser welding of the steel bar connection by the welding arm 13 is a commonly used process in existing industrial operations and will not be described in detail here.

[0024] In this embodiment, as a preferred solution, the first driving mechanism includes a first driving motor 14 and a first driving gear 15. The first driving motor 14 is arranged inside the base 1. The first driving motor 14 is meshed with the first driving gear 15 through gears, and the first driving gear 15 is meshed with the upper surface of the driving rail 3.

[0025] The first driving motor 14 rotates to drive the gear connected to one end, and drives the first driving gear 15 to rotate through the gear. The first driving gear 15 engages with the upper surface of the driving rail 3. During the rotation of the first driving gear 15, the base 1 is driven to move on the driving rail 3. The slide rail 2 is symmetrically arranged with the driving rail 3, and supports the base 1 on the other side. The base 1 is provided with an auxiliary wheel at a position above the slide rail 2. The auxiliary wheel rests on the slide rail 2 for auxiliary support, and the base 1 moves more smoothly.

[0026] In this embodiment, as a preferred solution, the fixing mechanism includes an interlaced plate 16, a pull rod 17 and a movable sleeve 18. The interlaced plate 16 is detachably arranged on the surface of the plug-in board 7 and is slidably connected to the plug-in board 7 up and down. An operating compartment 19 is opened inside the plug-in board 7. The pull rod 17 is fixedly connected to the inner wall of the operating compartment 19 through a rotating shaft. The movable sleeve 18 is slidably sleeved on the outer surface of the pull rod 17. A rotatable connecting rod 20 is provided on the side of the movable sleeve 18 close to the interlaced plate 16. One end of the connecting rod 20 is fixedly connected to the interlaced plate 16. A fixed plate 21 is provided on the surface of the plug-in board 7 on one side of the pull rod 17. A limit pin 22 is penetrated and connected to the middle part of the fixed plate 21, and the limit pin 22 also penetrates the pull rod 17 to fix the position of the pull rod 17.

[0027] The staggered plate 16 is movably connected to the plug-in plate 7 up and down, and a hole is also provided on the staggered plate 16. When the hole is aligned with the positioning hole 9, the steel bar can be inserted into the positioning hole 9. The pull rod 17 is rotatably arranged in the operation compartment 19. When the pull rod 17 is pushed upward, the movable sleeve 18 outside the pull rod 17 will move together. The movable sleeve 18 is connected to the connecting rod 20, and the connecting rod 20 is connected to the staggered plate 16. Therefore, when the pull rod 17 is pulled upward, the staggered plate 16 will be driven to move upward together, so that the hole on the staggered plate 16 is misaligned with the positioning hole 9, so that the steel bar in the positioning hole 9 is stuck in the positioning hole 9. When the pull rod 17 is pulled down, the movable sleeve 18 8 moves down, the connecting rod 20 moves down, and the staggered plate 16 moves down together, so that the holes on the staggered plate 16 are aligned with the positioning holes 9, so that the steel bars can be taken out from the positioning holes 9, and the connecting sleeve 6 is detachably connected to the connecting seat 8. When in use, a suitable plug-in plate 7 can be installed on the connecting seat 8 according to the diameter of the steel bars, so that the diameter of the positioning holes 9 matches the diameter of the steel bars. After the pull rod 17 is pushed to the top, the opening on the pull rod 17 is aligned with the opening on the fixing plate 21. After the limit pin 22 is inserted into the fixing plate 21, the pull rod 17 can be fixed to the fixing plate 21 to prevent the pull rod 17 from moving down, so that the staggered plate 16 can fix the steel bars to prevent them from accidentally falling off.

[0028] In this embodiment, as a preferred solution, the second driving mechanism includes a second driving motor 23 and a second driving gear 24. The second driving motor 23 is fixedly connected to one side of the driving end 4. The output end of the second driving motor 23 is meshed with the second driving gear 24 through a gear. The second driving gear 24 is fixedly connected to the connecting seat 8 through a transmission shaft.

[0029] The second drive motor 23 drives the second drive gear 24 to rotate. The second drive gear 24 is coaxially arranged with the connecting seat 8. During the rotation of the second drive gear 24, the connecting seat 8 will be driven to rotate together, thereby driving the plug-in board 7 at one end of the connecting seat 8 and the steel bars on the plug-in board 7 to rotate, making it convenient to wrap the steel wire around the surface of the steel bars.

[0030] In the present embodiment, as a preferred solution, the grinding mechanism includes a shell 25, a compression spring 36 and a clamping block 26. The compression spring 36 is arranged on the inner wall of the shell 25. The clamping block 26 is fixedly connected to one end of the compression spring 36. There are two clamping blocks 26, which are symmetrically arranged with the central axis of the shell 25 as the axis of symmetry. The opposite sides of the clamping blocks 26 are provided with grinding pads 27 for grinding off the oxide layer on the surface of the steel wire. A disassembly plate 28 is fixedly connected to the side of the shell 25. The compression spring 36 is fixedly connected to one side of the disassembly plate 28. A collection box 29 is detachably provided at the bottom of the shell 25.

[0031] The shell 25 is fixed to one side of the gantry 10, and the compression springs 36 on both sides move the clamping block 26 toward the middle so that the two clamping blocks 26 fit together. The clamping block 26 rubs against the incoming steel wire to remove the oxide layer on the surface of the steel wire, which is convenient for subsequent welding. A grinding pad 27 is provided in the middle of the clamping block 26 to increase the friction between the clamping block 26 and the steel wire, which is more efficient in removing the oxide layer on the surface of the steel wire. After the disassembly plate 28 is removed, the internal compression spring 36 and the clamping block 26 can be taken out together, which is convenient for replacing the grinding pad 27 on the surface of the clamping block 26 to maintain a good grinding efficiency. The dust generated by grinding will fall into the collection box 29 at the bottom, reducing the dust that escapes into the environment and improving the cleanliness of the working environment.

[0032] In this embodiment, as a preferred solution, a brake chamber 30 is opened inside the driven end 5, and a stop disk 31 is provided inside the brake chamber 30. The middle part of the stop disk 31 is fixedly connected to the connecting seat 8 on one side of the driven end 5 through a transmission shaft. A brake mechanism is provided inside the brake chamber 30 to fix the angle of the connecting seat 8. The brake mechanism includes an arc plate 32, a threaded rod 33 and a friction plate 34. The threaded rod 33 is threadedly connected to the top of the driven end 5 and penetrates into the brake chamber 30. The threaded rod 33 is rotatably connected to the arc plate 32. The friction plate 34 is fixedly connected to the bottom of the arc plate 32 to increase the friction between the arc plate 32 and the stop disk 31.

[0033] In the process of fixing the steel bar on the plug-in plate 7, the threaded rod 33 can be rotated to make the arc plate 32 at the bottom of the threaded rod 33 contact with the brake disc, thereby limiting the rotation of the brake disc and fixing the rotation angle of the plug-in plate 7. It is more convenient to insert the steel bar into the plug-in plate 7 and it is not easy to shake. When processing, the arc plate 32 is rotated in the opposite direction to separate the brake disc. The friction plate 34 arranged at the bottom of the arc plate 32 can increase the friction with the brake disc and improve the fixing effect.

[0034] In this embodiment, as a preferred solution, a telescopic rod 35 is fixedly connected to the top of the gantry 10 , and an output end of the telescopic rod 35 is fixedly connected to the top of the movable plate 11 to control the movement of the movable plate 11 .

[0035] The telescopic rod 35 drives the movable plate 11 to move up and down, so that the pressing plate 12 can always contact the highest point of the rotation of the steel bar. A groove is provided under the pressing plate 12 to limit the moving position of the steel wire to prevent the steel wire from escaping from the bottom of the pressing plate 12. When the pressing plate 12 squeezes the steel wire, the steel wire can better fit together with the steel bar, making it convenient for the welding arm 13 to weld the connection between the steel bar and the steel wire.

[0036] In the present invention, the working steps of the device are as follows: 1. When in use, move the driven end 5 to the bottom of the gantry 10, select the plug-in plate 7 and the staggered plate 16 of appropriate sizes according to the different sizes of steel bars to be made, fix the connecting sleeve 6 on the back of the plug-in plate 7 with the driven end 5 and the connecting seat 8 on the active end, rotate the threaded rod 33 to fix the plug-in plate 7 on the side of the driven end 5, and after fixing, insert the steel bars into the corresponding positioning holes 9 according to the required shape, push the pull rod 17 upward after plugging, so that the staggered plate 16 fixes the position of the steel bars, and use the limit pin 22 to fix the position of the pull rod 17; 2. After fixing one side of the driven end 5, fix the other end of the steel bar to the driving end 4 and also use the pull rod 17 to fix it. After fixing it, pass the steel wire through the grinding mechanism and weld one end of the steel wire to the steel bar. Adjust the height of the telescopic rod 35 so that the pressing plate 12 is flush with the highest point of the steel bar to squeeze the steel wire. 3. After the welding is completed, the first driving mechanism and the second driving mechanism are started, driving the driving end 4 to move toward the side of the gantry 10, while the connecting seat 8 drives the plug-in plate 7 to rotate, driving the steel bars connected to the plug-in plate 7 to rotate, and the welding arm 13 welds the connection position of the steel wire and the steel bar together during the rotation; 4. After welding is completed, remove the limit pin 22, pull down the pull rod 17 and remove the steel bar from the positioning hole 9.
