Description

Technical Field

[0001] The invention relates to the technical field of steel cage production, in particular to a steel cage rolling welding machine. Background Art

[0002] In the construction of large bridges and other engineering projects, a large number of piles need to be constructed. In the construction of these piles, a large number of steel cages need to be processed. In the prior art, a steel cage rolling welding machine is a commonly used equipment for making steel cages. The steel cage is mainly composed of three parts: main bars, winding bars, and inner support bars. The main bars are the main body, the winding bars are wound around the outside of the main bars to reinforce the main bars, and the inner support bars are arranged on the inside of the main bars to support the main bars. Conventional automatic steel cage rolling welding machines include the functions of automatically winding the winding bars and welding the winding bars. For the inner support bars, manual positioning and manual welding are still used; Some steel cage rolling welding machines also have the functions of automatically positioning the internal support bars and automatically welding the internal support bars, but the step of welding the internal support bars is set before welding the winding bars. However, the internal support bars have a strong force to deform outward. If the internal support bars cannot be firmly limited during the positioning process, the internal support bars will deform outward, making it difficult to position the internal support bars. The positioning difficulty will also lead to inaccurate welding. Summary of the invention

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1.

Because the connection between the hollow rod and the placement tube is carried out by a detachable joint, when producing steel cages with different inner diameters, the placement tube of the corresponding specification can be replaced; 3. The movable plate is extended to move rightward by the second cylinder, thereby increasing the tilt angle of the rotating rod until the second roller contacts the inner side of the steel cage body. At this time, the inner support bar is tightly pressed against the inner side of the steel cage body, so that when the steel cage body moves to the right, it can drive the inner support bar to move to the right. If the inner support bar tilts, one of the three second rollers will contact the inner support bar first, and then stop the inner support bar from moving rightward, so that the inner support bar is gradually straightened, and then the movable plate is driven to move leftward by the second cylinder, so that the tilt angle of the rotating rod becomes smaller, and then the second roller no longer prevents the inner support bar from moving; 4. Adjust the position of the mounting seat through cylinder three, and then adjust the position of cylinder four, so that welding gun two at the bottom of cylinder four is aimed at the joint between the inner support reinforcement and the main reinforcement, and drive welding gun two to approach the joint between the inner support reinforcement and the main reinforcement through cylinder four, so that welding gun two can perform welding.

A connecting piece 8 is fixedly mounted on the left side of the rotating disk 203 by bolts. The right end of the main rib 6 is fixedly connected to the rotating disk 203 by the connecting piece 8, so that when the movable seat 2 moves to the right along the slide rail 1, the main rib 6 can be driven to move, and when the rotating disk 203 rotates, the main rib 6 can be driven to rotate; The fixing seat 3 includes a bottom plate 301, a vertical plate 302, and a rotating disk 303.

The rotation of the gear 32 drives the gear 2 31 to rotate, thereby driving the hollow rod 12 to rotate. The rotation of the hollow rod 12 drives the placement tube 15 to rotate, so that the placement tube 15 and the main body of the steel cage rotate synchronously, thereby reducing the radial friction between the placement tube 15 and the inner side of the steel cage when the placement tube 15 supports the inner side of the steel cage, and at the same time, when the inner support bar 10 is pushed out of the placement tube 15, the inner support bar 10 itself also rotates, thereby reducing the friction between the inner support bar 10 and the inner side of the steel cage when it is against the inner side of the steel cage; An arc frame 26 is fixedly installed on the top of the slide rail 1, a connecting ring 27 is fixedly installed on the outer wall of the hollow rod 12, a guide rod 28 is fixedly installed on the outer wall of the connecting ring 27, a plurality of guide rods 28 are provided, and a circular array is distributed on the connecting ring 27, a roller three 29 is fixedly installed on the end of the guide rod 28, and the roller three 29 is slidably set in the arc frame 26, and the hollow rod 12 that rotates synchronously with the rotating disk 1 203 drives the connecting ring 27 to rotate, and then drives the guide rod 28 to rotate, so that the guide rod 28 can separate and guide multiple main bars 6 to avoid the main bars 6 from being entangled.

If the inner support bar 10 tilts, one of the three rollers 25 will contact the inner support bar 10 first, and then stop the inner support bar 10 from continuing to move to the right here, so that the inner support bar 10 is gradually straightened, and then the movable plate 23 is driven to move to the left by the cylinder two 22, so that the inclination angle of the rotating rod 24 becomes smaller, and then the roller two 25 no longer prevents the inner support bar 10 from moving. Because the roller two 25 can be rotated under force, when the roller two 25 contacts the inner side of the steel cage body, the friction between the roller two 25 and the inner side of the steel cage is small.

[0021] Working principle: when in use, according to the specifications of the steel cage to be produced, select a placement tube 15 of corresponding size, connect the placement tube 15 to the right end of the hollow rod 12, use a loading machine to press multiple internal support bars 10 into the placement tube 15 in sequence, and then pass the main bar 6 through the through hole on the rotating disk 2 303, and then fix the right end of the main bar 6 with the connecting piece 8, install multiple main bars 6 in sequence to form the steel cage body, and use the moving seat 2 to pull the main bar 6 to move right while driving the steel cage body to rotate, so that the winding bar 7 can be wound on the steel cage body. During the winding process of the winding bar 7, the electric adjustment seat 4 adjusts the angle and position of the welding gun 5 so that the welding gun 5 is aimed at the joint between the winding bar 7 and the main bar 6, and then welding is performed. After the steel cage body moves a certain distance, the cylinder 17 is turned on to drive the annular push plate 18 to move to the right, so that the annular push plate 18 will push the inner The support bar 10 is pushed outside the placement tube 15, and the inner support bar 10 is deformed outwardly quickly until the inner support bar 10 is tightly against the inner side of the steel cage. At the same time, the cylinder 22 is turned on to drive the movable plate 23 to move to the right, thereby increasing the inclination angle of the rotating rod 24 until the roller 25 contacts the inner side of the steel cage body. At this time, because the inner support bar 10 is tightly against the inner side of the steel cage body, the steel cage body can drive the inner support bar 10 to move to the right when it moves to the right. If the inner support bar 10 tilts, one of the three rollers 25 will contact the inner support bar 10 first, and then stop the inner support bar 10 from continuing to move to the right here, so that the inner support bar 10 is gradually straightened, and then the movable plate 23 is driven to move to the left by the cylinder 22, so that the inclination angle of the rotating rod 24 becomes smaller, and then the roller 25 no longer prevents the inner support bar 10 from moving. At this time, the joint between the inner support bar 10 and the main bar 6 can be welded.

[0023] Working principle: When in use, according to the specifications of the steel cage to be produced, select the placement tube 15 of the corresponding size, connect the placement tube 15 with the right end of the hollow rod 12, use the feeding machine to press multiple inner support bars 10 into the placement tube 15 in sequence, and then pass the main bar 6 through the through hole on the rotating disk 2 303, and then fix the right end of the main bar 6 with the connecting piece 8, and install multiple main bars 6 in sequence to form the main body of the steel cage. The main bar 6 is pulled to the right by the moving seat 2, and the main body of the steel cage is driven to rotate, so that the winding bar 7 can be wound on the main body of the steel cage. During the winding process, the electric adjustment seat 4 adjusts the angle and position of the welding gun 5 so that the welding gun 5 is aligned with the joint between the winding reinforcement 7 and the main reinforcement 6, and then welding is performed. After the main body of the steel cage moves a certain distance, the cylinder 17 is turned on to drive the annular push plate 18 to move to the right, so that the annular push plate 18 pushes the rightmost inner support reinforcement 10 to the outside of the placement tube 15, and the inner support reinforcement 10 is quickly deformed outward until the inner support reinforcement 10 is tightly against the inner side of the steel cage. At the same time, the cylinder 22 is turned on to drive the movable plate 23 to move to the right, thereby changing the tilt angle of the rotating rod 24. The inner support bar 10 is large until the roller 25 contacts the inner side of the steel cage body. At this time, the inner support bar 10 is tightly pressed against the inner side of the steel cage body, so that when the steel cage body moves to the right, it can drive the inner support bar 10 to move to the right. If the inner support bar 10 tilts, one of the three rollers 25 will contact the inner support bar 10 first, and then stop the inner support bar 10 from moving to the right, so that the inner support bar 10 is gradually straightened, and then the movable plate 23 is driven to move to the left through the cylinder 22, so that the tilt angle of the rotating rod 24 becomes smaller, so that the roller 25 no longer prevents the inner support bar 1 0 move, open cylinder three 38 to adjust the position of the mounting seat 39, so that the welding gun two 41 at the bottom of the cylinder four 40 is aimed at the joint between the inner support rib 10 and the main reinforcement 6, and the welding gun two 41 is driven by the cylinder four 40 to approach the joint between the inner support rib 10 and the main reinforcement 6, so that the welding gun two 41 can perform welding. After three positions of welding, the cylinder three 38 can be opened to continue to move to the right, and keep the synchronous movement speed with the steel cage. When the steel cage rotates, the joint between the inner support rib 10 and the main reinforcement 6 can be switched, so that the welding gun two 41 can weld the remaining joints.
