Description

Technical Field

[0001] This invention relates to the field of steel frame welding, and more particularly to an intelligent welding device and method for shear wall steel frames. Background Technology

[0002] Reinforcing steel bars are mainly used for reinforcing shear wall steel frames. They are fixed to the wall through anchoring, welding, or bolting to enhance the integrity and stability of the wall. By strengthening the connection between the wall and the reinforcing components, the reinforcing steel bars prevent the structure from deforming or failing under load. Reinforcing steel bars play a key role in shear wall reinforcement, not only improving the load-bearing capacity of the structure but also enhancing its seismic performance and durability. To save assembly and welding time on the shear wall steel frame, existing reinforcing steel bars are usually pre-welded in the production workshop.

[0003] The pre-welding process involves attaching the end of one reinforcing steel bar to the side edge of another, and then welding the two intersecting reinforcing steel bars together. When the end of the abutting reinforcing steel bar is not a flat surface, it is necessary to perform additional flat cutting on the end of the abutting reinforcing steel bar. In particular, when the corner area of ​​the shear wall steel frame is an obtuse angle structure, it is necessary to perform additional bevel cutting on the end of the abutting reinforcing steel bar so that the two intersecting reinforcing steel bars are placed at a corresponding obtuse angle. Therefore, the overall pre-welding process of the two reinforcing steel bars is quite complicated, and it is difficult to meet the requirement of a flat and complete cut by manually cutting the ends of the reinforcing steel bars. Summary of the Invention

[0004] To overcome the drawbacks of the cumbersome pre-welding process for the two reinforcing steel bars and the difficulty in achieving a smooth and complete cut by manually cutting the ends of the reinforcing steel bars, this invention provides an intelligent welding device and method for shear wall steel frames.

[0008] Furthermore, a limiting block is slidably connected to the second fixed insertion rail to prevent the second reinforcing steel bar from wobbling excessively.

[0009] Furthermore, a grinding disc is fixed to the side of the circular saw cutting blade facing the second fixed rail of the electric circular saw cutting machine.

[0010] Furthermore, an electromagnet is installed on the second fixed rail to generate an electromagnetic attraction force on the second reinforcing steel bar.

[0011] Furthermore, a first scale for measuring the length of the first reinforcing steel bar is fixedly connected to the first fixed rail; a second scale for measuring the length of the second reinforcing steel bar is fixedly connected to the second fixed rail.

A rotary control motor 25 is provided; a gear 26 is fixedly connected to the output shaft of the rotary control motor 25; the gear 26 meshes with an arc-shaped rack 24; a fixed support frame 14 is installed on the right side of the mounting frame 11; a second electrically controlled turntable 15 is installed on the fixed support frame 14; a second fixed plate 31 is fixedly connected to the rotating part of the second electrically controlled turntable 15; a second fixed rail 32 is connected to the second fixed plate 31; an electrically controlled multi-axis robot 41 is connected to the mounting frame 11; an electrically controlled welding gun 42 is connected to the electrically controlled multi-axis robot 41; a connecting shaft 231 for rotating connection of the first fixed rail 23 to the first fixed frame 21 is provided at the bottom of the first fixed rail 23; an electrically controlled circular saw cutter 5 is installed on the connecting shaft 231 at the bottom of the first fixed rail 23; the circular saw cutting blade of the electrically controlled circular saw cutter 5 is aligned with the right edge of the first reinforcing steel bar 61 inserted on the first fixed rail 23; a grinding disc 51 is fixedly connected to the side of the circular saw cutting blade of the electrically controlled circular saw cutter 5 facing the second fixed rail 32.

[0021] like Figure 4 and Figure 5 As shown, a connecting rod 36 is slidably connected to the second fixed insertion rail 32; a second electric push rod 37 is installed on the second fixed insertion rail 32; the telescopic end of the second electric push rod 37 is fixedly connected to the connecting rod 36; a support plate 38 is fixedly connected to the connecting rod 36; a slot structure 200 for aligning the support plate 38 is provided on the first fixed insertion rail 23; and a limit block 39 is slidably connected to the second fixed insertion rail 32.

[0022] The following are the operating steps of an intelligent welding device for shear wall steel frames in this embodiment.

[0023] First, the operator inserts the first reinforcing steel bar 61 into the first fixed rail 23, and then inserts the second reinforcing steel bar 62 into the second fixed rail 32. Figure 6As shown, viewed from a top-down angle, the first reinforcing steel bar 61 and the second reinforcing steel bar 62 are perpendicular to each other, with the left side of the second reinforcing steel bar 62 passing through the limiting block 39. At this time, the right edge of the first reinforcing steel bar 61 is aligned with the circular saw cutting blade of the electric circular saw cutting machine 5. The operator pushes the second reinforcing steel bar 62 to the left along the second fixed insertion rail 32, moving it closer to the bottom of the electric circular saw cutting machine 5, so that the excess part of the second reinforcing steel bar 62 is aligned with the bottom of the circular saw cutting blade of the electric circular saw cutting machine 5. At the same time, the second electric push rod 37 pushes the connecting rod 36, causing the support plate 38 to move to the left until it is close to the bottom left end of the second reinforcing steel bar 62. The support plate 38 supports and fixes the bottom left end of the second reinforcing steel bar 62, while the limiting block 39 limits and fixes the left side of the second reinforcing steel bar 62 to prevent it from shaking. The rear electric lifting platform 12 drives the first electric turntable 13 and its first fixed frame 21, arc-shaped slider 22, first fixed rail 23, first reinforcing steel bar 61 and electric circular saw cutting machine 5 to move downwards. At the same time, the electric circular saw cutting machine 5 cuts off the excess part of the second reinforcing steel bar 62 downwards through the circular saw cutting blade. At the same time, the electric circular saw cutting machine 5 drives the grinding disc 51 to grind the cut surface of the second reinforcing steel bar 62 flat, thereby cutting the left end of the second reinforcing steel bar 62 into a flat cross-section that is completely aligned with the right edge of the first reinforcing steel bar 61. When the circular saw cutting blade of the electric circular saw cutting machine 5 is about to cut through the second reinforcing steel bar 62 downwards, the second electric push rod 37 pulls the connecting rod 36 to drive the support plate 38 to move to the right and reset, so as to avoid the electric circular saw cutting machine 5 from cutting the connecting rod 36 and the support plate 38.

[0024] After the electric circular saw cutting machine 5 completely cuts away the excess parts of the second reinforcing steel bar 62, the electric lifting machine 12 continues to drive the first electric turntable 13 and its first fixed frame 21, arc-shaped slider 22, first fixed rail 23, first reinforcing steel bar 61, and electric circular saw cutting machine 5 to move downwards until the right edge of the first reinforcing steel bar 61 in the first fixed rail 23 is tightly against the left end cut surface of the second reinforcing steel bar 62 in the second fixed rail 32. Then, the second electric push rod 37 pushes the connecting rod 36 to move the support plate 38 to the left until the support plate 38 is inserted into the slot structure 200 of the first fixed rail 23. Then the first electric... The control turntable 13 drives the first fixed frame 21 and its connected first fixed rail 23 and first reinforcing steel bar 61 to rotate vertically. Simultaneously, the second electrically controlled turntable 15 drives the second fixed plate 31 and its connected second reinforcing steel bar 62 to rotate vertically. At this time, the first fixed rail 23 and the second fixed rail 32 are connected as one unit through the support plate 38 and the slot 200, thus ensuring that the first reinforcing steel bar 61 and the second reinforcing steel bar 62 can rotate synchronously. At the same time, the electrically controlled multi-axis manipulator 41 controls the electrically controlled welding gun 42 to weld the connection between the rotating first reinforcing steel bar 61 and the second reinforcing steel bar 62 from bottom to top. Figure 7As shown, the conventional vertical structural splicing and welding work of the first reinforcing steel bar 61 and the second reinforcing steel bar 62 is automatically completed.

[0025] like Figure 4 As shown, an electromagnet 310 is installed on the second fixed rail 32; during the grinding process of the grinding disc 51 grinding the cut surface of the second reinforcing steel strip 62 flat, the electromagnet 310 generates an electromagnetic attraction force on the second reinforcing steel strip 62 on the second fixed rail 32, so that the second reinforcing steel strip 62 is firmly fixed on the second fixed rail 32, and the grinding disc 51 is prevented from pushing the second reinforcing steel strip 62 to move laterally along the second fixed rail 32 during the grinding process.

[0026] When the first reinforcing steel bar 61 and the second reinforcing steel bar 62 need to form an obtuse angle splicing structure, after the operator inserts the first reinforcing steel bar 61 into the first fixed insert rail 23, the rotary control motor 25 drives the gear 26 to rotate. The gear 26 meshes with the arc-shaped rack 24, causing the arc-shaped slider 22 and the first fixed insert rail 23 and the first reinforcing steel bar 61 to rotate horizontally until the first reinforcing steel bar 61 is in a tilted state at a specified angle. The electric circular saw cutting machine 5 will also rotate with the connecting shaft 231 of the first fixed frame 21 to a tilted state at a specified angle. Then, as the electric lifting machine 12 drives the first electric turntable 13 and the first fixed frame 21, arc-shaped slider 22, first fixed insert rail 23, first reinforcing steel bar 61 and electric circular saw cutting machine 5 to move downwards, the electric circular saw cutting machine 5 cuts the left end of the second reinforcing steel bar 62 into an inclined cut surface structure aligned with the right edge of the first reinforcing steel bar 61. Figure 8 As shown, the first reinforcing steel bar 61 and the second reinforcing steel bar 62 can be spliced ​​at the required obtuse angle. Then, following the above steps, the electric welding gun 42 is controlled by the electric multi-axis robot 41 to weld the connection between the rotating first reinforcing steel bar 61 and the second reinforcing steel bar 62 from bottom to top, so as to automatically complete the obtuse angle structure splicing and welding work of the first reinforcing steel bar 61 and the second reinforcing steel bar 62.

[0027] Example 2, as Figures 1-5As shown, based on the above embodiment 1, a first scale 27 is fixedly connected to the first fixed rail 23 in this embodiment; a second scale 34 is fixedly connected to the second fixed rail 32, and the second scale 34 starts from the position of the electric circular saw cutting machine 5 as the zero mark; two first sliding pointers 28 are slidably connected to the first fixed rail 23; a second sliding pointer 35 is slidably connected to the second fixed rail 32; after the operator inserts the first reinforcing steel bar 61 into the first fixed rail 23, the two first sliding pointers 28 are slidably connected to align with the two ends of the first reinforcing steel bar 61 respectively. The difference between the readings on scale 27 is the length of the first reinforcing steel bar 61. After the operator inserts the second reinforcing steel bar 62 onto the second fixed rail 32, the operator slides the second sliding pointer 35 to align the end of the second reinforcing steel bar 62 away from the electric circular saw cutting machine 5. The value of the second sliding pointer 35 on the second scale 34 is the length of the second reinforcing steel bar 62. This allows for rapid measurement of the lengths of the first and second reinforcing steel bars 61 and 62, making it easier to adjust their positions on the first and second fixed rails 23 and 32 respectively.

[0028] Example 3, as Figures 1-5As shown, based on the above embodiment 1, the second fixed rail 32 of this embodiment is slidably connected to the second fixed plate 31; a first electric push rod 33 is installed on the second fixed plate 31; the telescopic end of the first electric push rod 33 is fixed to the second fixed rail 32; before the electric circular saw cutting machine 5 cuts the excess part of the second reinforcing steel bar 62 on the second fixed rail 32, the first electric push rod 33 first pushes the second fixed rail 32 to move to the left along the second fixed plate 31 until the second fixed rail 32 drives the second reinforcing steel bar 62 to move 5cm to the left, so that the excess part of the second reinforcing steel bar 62 is aligned with the bottom of the electric circular saw cutting machine 5 at 5cm to the right. Then the electric lifting machine 12 controls the first fixed frame 21 to drive the electric circular saw cutting machine 5 to move downward, and the electric circular saw cutting machine 5 cuts a groove structure 600 at 5cm to the right of the area to be cut on the upper surface of the excess part of the second reinforcing steel bar 62. The electric lifting platform 12 controls the first fixed frame 21 to drive the electric circular saw cutter 5 to return to its original position. The first electric push rod 33 pulls the second fixed rail 32 to move to the right along the second fixed plate 31, resetting the second fixed rail. This allows the excess portion of the second reinforcing steel bar 62 to align with the electric circular saw cutter 5 again. Following the same steps, the electric lifting platform 12 controls the first fixed frame 21 to drive the electric circular saw cutter 5 downwards, cutting off the excess portion of the second reinforcing steel bar 62. The grinding disc 51 then smooths the cut surface of the second reinforcing steel bar 62. After the electric lifting platform 12 controls the first fixed frame 21 to align the first reinforcing steel bar 61 on the first fixed rail 23 with the cut surface of the second reinforcing steel bar 62, the operator inserts one side of the L-shaped reinforcing insert 63 downwards into the groove structure 600 of the second reinforcing steel bar 62, and the other side of the L-shaped reinforcing insert 63 is pressed tightly against the surface of the first reinforcing steel bar 61. Figure 9 As shown, in subsequent welding work, the L-shaped reinforcing insert 63 is firmly welded together with the first reinforcing steel bar 61 and the second reinforcing steel bar 62 using an electrically controlled welding gun 42, as follows: Figure 10 As shown, the L-shaped reinforcing insert 63 can increase the welding area between the first reinforcing steel bar 61 and the second reinforcing steel bar 62, thereby strengthening the welding stability between the first reinforcing steel bar 61 and the second reinforcing steel bar 62.
