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 existing technology, a steel cage roll welding machine is a commonly used equipment for making steel cages. The steel cage is mainly composed of three parts: main bars, wrap bars, and inner support bars. The main bars are the main body, the wrap bars are wrapped 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 roll welding machines include the functions of automatically winding the wrap bars and welding the wrap bars. For the inner support bars, manual positioning and manual welding are still used.

[0003] 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, which will make it difficult to position the internal support bars. The positioning difficulty will also lead to inaccurate welding. Summary of the Invention

The guide wheels are divided into two groups, and the ribs pass between the upper and lower groups of guide wheels.

[0011] Furthermore, a U-shaped seat is fixedly installed at the bottom of the base plate 1, a dual-axis motor is fixedly installed on the inner side of the U-shaped seat, a rotating shaft 1 is fixedly installed on the output end of the dual-axis motor, a gear 1 is fixedly installed on the outer wall of the rotating shaft 1, the gear 1 is engaged with a rack, the rack is fixedly installed on the inner side of the slide rail, and the inner side of the vertical plate 1 is rotatably connected to a roller 1 through a pin shaft, and the roller 1 rests on a rotating disk 1.

[0012] Furthermore, a servo motor is fixedly mounted on the right outer wall of the stand, a rotating shaft 2 is fixedly mounted on the output end of the servo motor, a gear 3 is fixedly mounted on the outer wall of the rotating shaft 2, the gear 3 is meshed with the gear 2, and the gear 2 is fixedly mounted on the hollow rod.

[0017] Furthermore, there are three cylinders three, which are distributed in a circular array around the central axis of the rotating disk two, and the welding gun two is located on the right side of the welding gun one.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The cylinder pushes the annular push plate to the right, thereby pushing the inner support bar to the right. After the rightmost inner support bar moves outside the placement tube, the inner support bar itself can be deformed outward, thereby making the inner support bar against the inner side of the steel cage body, realizing the placement of the inner support bar without manual operation. At this time, the steel cage body has been formed, and the inner support bar can be directly limited, so that the inner support bar is tightly against the inner side of the steel cage, which is convenient for positioning the inner support bar, and then the inner support bar is welded;

[0020] 2. Because the placement tube passes through the center hole in the center of the rotating disk 2, the rotation of the rotating disk 2 will not drive the placement tube to rotate. Moreover, because the placement tube is located inside the main body of the steel cage, the steel cage will not collide with the placement tube when it rotates and moves to the right. In addition, the placement tube can serve as an inner support inside the steel cage. Because the connection between the hollow rod and the placement tube is carried out by a detachable joint, the placement tube of the corresponding specification can be replaced when producing steel cages with different inner diameters.

[0021] 3. The second cylinder is extended to drive the movable plate to move to the right, 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 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 further to the right, so that the inner support bar is gradually straightened. Then, the second cylinder drives the movable plate to move to the left, causing the tilt angle of the rotating rod to decrease, and the second roller no longer prevents the movement of the inner support bar.

[0022] 4. Adjust the position of the mounting base through cylinder three, and then adjust the position of cylinder four, so that the welding gun two at the bottom of cylinder four is aligned with the joint between the inner support reinforcement and the main reinforcement. Cylinder four drives the welding gun two to approach the joint between the inner support reinforcement and the main reinforcement, so that the welding gun two can perform welding.

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] Example 1

[0036] See also Figure 1-Figure 7 The present invention provides a technical solution: a steel cage rolling welding machine, comprising a slide rail 1, a movable seat 2, a fixed seat 3, a main reinforcement 6, a surrounding reinforcement 7, and an inner support reinforcement 10, wherein the movable seat 2 is slidably arranged on the slide rail 1, and the fixed seat 3 is fixedly installed on the slide rail 1;

[0037] The movable seat 2 includes a bottom plate 201, a vertical plate 202, and a rotating disk 203. The vertical plate 202 is fixedly mounted on the bottom plate 201, and the rotating disk 203 is rotatably arranged in the vertical plate 202. A connecting piece 8 is fixedly mounted on the left side of the rotating disk 203 by bolts. The right end of the main reinforcement 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 reinforcement 6 can be driven to move, and when the rotating disk 203 rotates, the main reinforcement 6 can be driven to rotate.

[0038] The fixing seat 3 includes a second bottom plate 301, a second vertical plate 302, and a second rotating disk 303. The second vertical plate 302 is fixedly mounted on the second bottom plate 301. The second rotating disk 303 is rotatably disposed within the second vertical plate 302. A center hole 9 is provided at the center of the second rotating disk 303. The second rotating disk 303 is provided to guide and support the main reinforcement 6 so that when the winding reinforcement 7 is wound around the main reinforcement 6, the main reinforcement cage body formed by the main reinforcement 6 will not sink inward.

[0039] A stand 11 is fixedly installed on the top of the left end of the slide rail 1. The inner wall of the stand 11 is rotatably connected to a hollow rod 12 through a bearing. A rotary joint 13 is provided at the left end of the hollow rod 12. The rotary joint 13 is connected to the compressed air pipeline of the workshop. The right end of the hollow rod 12 is fixedly connected to a placement cylinder 15 through a detachable joint 14. An air cavity 16 is fixedly installed on the left inner wall of the placement cylinder 15. The air cavity 16 is connected to the inside of the hollow rod 12. A cylinder is fixedly installed on the left inner wall of the placement cylinder 15. The air inlet and outlet ends of the cylinder 17 are connected to the air cavity 16 through a pipe. The elongated end of the cylinder 17 is fixedly installed with an annular push plate 18. A plurality of inner supporting ribs 10 are arranged in sequence from left to right in the placement cylinder 15. The right side of the annular push plate 18 contacts the inner supporting ribs 10. Because the placement cylinder 15 passes through the center hole 9 in the center of the rotating disk 2 303, the rotation of the rotating disk 2 303 will not drive the placement cylinder 15 to rotate, and because the placement cylinder 15 is located between the steel bars The inner side of the cage body, thereby making the steel cage not collide with the placement tube 15 when it rotates and moves to the right, and the placement tube 15 can play the role of inner support on the inner side of the steel cage, because the connection between the hollow rod 12 and the placement tube 15 is carried out by relying on the detachable joint 14. When producing steel cages with different inner diameters, the placement tube 15 of corresponding specifications can be replaced. After a certain distance, the annular push plate 18 can be pushed to the right by the cylinder 17, thereby pushing the inner support rib 10 to move to the right. After the rightmost inner support rib 10 moves to the outside of the placement tube 15, the inner support rib 10 itself can be deformed outward, thereby making the inner support rib 10 press against the inner side of the steel cage body, realizing the placement of the inner support rib 10 without manual operation, and at this time the steel cage body has been formed, and the inner support rib 10 can be directly limited, so that the inner support rib 10 is tightly pressed against the inner side of the steel cage, which is convenient for positioning the inner support rib 10, and then welding the inner support rib 10;

[0040] An electric adjustment seat 4 is provided on the front of the slide rail 1. A welding gun 5 is fixedly installed on the movable end of the electric adjustment seat 4. The electric adjustment seat 4 is located between the movable seat 2 and the fixed seat 3, and the electric adjustment seat 4 is close to the right side of the fixed seat 3. The electric adjustment seat 4 is provided to adjust the angle of the welding gun 5, and the welding gun 5 is used to weld the winding reinforcement 7 wrapped around the main reinforcement 6;

[0041] A mounting plate 34 is fixedly mounted on the front of the second vertical plate 302, a guide plate 35 is fixedly mounted on the right side of the mounting plate 34, and a guide wheel 36 is fixedly mounted on the inner wall of the guide plate 35. The guide wheels 36 are divided into two groups, upper and lower, and the rib 7 passes between the upper and lower groups of guide wheels 36. The front and rear ends of the mounting plate 34 are rotatably connected to limit rollers 37 through pins. The guide wheels 36 straighten and guide the rib 7. The limit rollers 37 are provided to limit the rib 7 to prevent it from escaping from the guide plate 35.

[0042] A U-shaped seat 208 is fixedly installed at the bottom of the base plate 201, and a dual-axis motor 206 is fixedly installed on the inner side of the U-shaped seat 208. A rotating shaft 207 is fixedly installed on the output end of the dual-axis motor 206, and a gear 205 is fixedly installed on the outer wall of the rotating shaft 207. The gear 205 is meshed with a rack 204, and the rack 204 is fixedly installed on the inner side of the slide rail 1. The inner side of the vertical plate 202 is rotatably connected to a roller 209 through a pin shaft. The roller 209 is against the rotating disk 203, and the dual-axis motor 206 drives the rotating shaft 207 to rotate, thereby driving the gear 205 to rotate. The rotation of the gear 205 is pushed by the rack 204, so that the movable seat 2 can move along the slide rail 1. The provision of the roller 209 reduces the friction force on the rotating disk 203 when it rotates, and the roller 209 can limit the rotating disk 203.

[0043] A servo motor 30 is fixedly mounted on the right outer wall of the stand 11, and a rotating shaft 2 33 is fixedly mounted on the output end of the servo motor 30. A gear 32 is fixedly mounted on the outer wall of the rotating shaft 2 33. The gear 32 is meshed with the gear 2 31. The gear 2 31 is fixedly mounted on the hollow rod 12. The servo motor 30 drives the rotating shaft 2 33 to rotate, thereby driving the gear 3 32 to rotate. 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 cylinder 15 to rotate, so that the placement cylinder 15 and the steel cage body rotate synchronously, thereby reducing the radial friction between the placement cylinder 15 and the inner side of the steel cage when the placement cylinder 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 cylinder 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 pressed against the inner side of the steel cage;

[0044] An arc-shaped 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, and a guide rod 28 is fixedly installed on the outer wall of the connecting ring 27. There are multiple guide rods 28, and a circular array is distributed on the connecting ring 27. The end of the guide rod 28 is fixedly installed with a roller three 29, and the roller three 29 is slidably set in the arc-shaped frame 26. The hollow rod 12 rotates synchronously with the rotating disk 1 203, driving the connecting ring 27 to rotate, and then driving the guide rod 28 to rotate, so that the guide rod 28 can separate and guide multiple main bars 6 to prevent the main bars 6 from being entangled.

[0045] 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 loading machine to press multiple inner support bars 10 into the placement tube 15 in sequence, 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 the right while driving the steel cage body to rotate, so that the winding bar 7 can be wrapped around the steel cage main body. On the body, during the winding process of the rebar 7, 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 rebar 7 and the main rebar 6, and then welding is performed. After each movement of the steel cage body, 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 bar 10 to the outside of the placement tube 15, and the inner support bar 10 is quickly deformed outward until the inner support bar 10 is tightly against the inside of the steel cage. At this time, the joint between the inner support bar 10 and the main rebar 6 can be welded.

[0054] An arc-shaped frame 26 is fixedly mounted on the top of the slide rail 1, a connecting ring 27 is fixedly mounted on the outer wall of the hollow rod 12, and a guide rod 28 is fixedly mounted on the outer wall of the connecting ring 27.

[0055] A connecting cylinder 19 is fixedly installed on the right end of the air cavity 16, and a guide cylinder 20 is fixedly installed on the right end of the connecting cylinder 19. A through groove 21 is provided on the outer wall of the guide cylinder 20, and a cylinder 22 is fixedly installed on the inner wall of the connecting cylinder 19.

A groove is provided on the outer wall of the movable plate 23, and a rotating rod 24 is rotatably connected to the inner side of the groove through a pin. The middle section of the rotating rod 24 is rotatably connected to the inner wall of the through groove 21 through a pin. There are three rotating rods 24, and a circular array is distributed on the movable plate 23. A roller 25 is fixedly installed on the end of the rotating rod 24. After the inner support rib 10 is pushed out of the placement tube 15, the movable plate is driven by the extension of the cylinder 22. 23 moves to the right, thereby increasing the tilt angle of the rotating rod 24 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 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 the left by the cylinder 22, so that the tilt angle of the rotating rod 24 becomes smaller, and then the roller 25 no longer prevents the inner support bar 10 from moving. Because the roller 25 can be rotated under force, when the roller 25 contacts the inner side of the steel cage body, the friction between the roller 25 and the inner side of the steel cage is small.

[0056] 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, and 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 to the connecting piece 8, and 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 the 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 carried out. After each movement of the steel cage body, 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 move the inner The supporting bar 10 is pushed outside the placement tube 15, and the inner supporting bar 10 is quickly deformed outward until the inner supporting 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 supporting bar 10 is tightly against the inner side of the steel cage body, the steel cage body can drive the inner supporting bar 10 to move to the right when it moves to the right. If the inner supporting bar 10 tilts, one of the three rollers 25 will contact the inner supporting bar 10 first, and then stop the inner supporting bar 10 from continuing to move to the right here, so that the inner supporting 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 supporting bar 10 from moving. At this time, the joint between the inner supporting bar 10 and the main bar 6 can be welded.
