Description

Technical Field

[0001] This invention relates to the field of miniature steel cage processing technology, and more specifically, to a miniature steel cage welding device. Background Technology

[0002] The main function of the reinforcing cage is similar to that of the longitudinal reinforcement in a column, primarily resisting tension. Concrete has high compressive strength but very low tensile strength. It acts as a constraint on the concrete of the pile, enabling it to withstand a certain amount of axial tensile force.

[0003] The steel cage is mainly composed of multiple main bars and coiled bars welded together. When processing large steel cages for building construction, according to the construction requirements, the main bars of the steel cage are fixed by manually passing them through the corresponding round holes of the template on the fixed rotating plate to the corresponding holes on the moving rotating plate. The ends of the coiled bars are first welded to a main bar. Then, the coiled bars are wound around the main bar by rotating the fixed rotating plate and the moving rotating plate, and welding is carried out at the same time to form the product steel cage.

[0004] Miniature steel cages have a diameter of less than 5 cm, with smaller main reinforcing bars. The welding spacing between the coiled bars and the main reinforcing bars is also denser. Existing steel cage processing equipment is designed for processing large steel cages used in building construction and cannot produce miniature steel cages. Furthermore, the usage of miniature steel cages is much greater than that of large steel cages, thus creating a need for mass production of miniature steel cages. Summary of the Invention

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components.

[0043] Furthermore, in this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Moreover, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0044] Figure 1 An embodiment of the present invention is shown, which includes a lathe 1 and a feeding mechanism 2 disposed on one side of the lathe 1 for feeding the coiled rib 21.

[0045] The positioning mechanism 3, which drives the rotation of multiple main ribs 20, is connected to the spindle box 11 of the lathe 1 in a transmission manner.

[0046] The rotating mechanism 4, which is used to drive the multiple main ribs 20 to move laterally, is installed on the slide box 12 of the lathe 1.

[0047] Welding mechanism 5 is provided corresponding to the positioning mechanism 3;

[0048] The solder joint sensing mechanism 6 is provided corresponding to the positioning mechanism 3, and the solder joint sensing mechanism 6 is communicatively connected to the welding mechanism 5.

[0049] Working principle: When welding and fabricating a miniature steel cage, multiple main reinforcing bars 20 are connected to the rotating mechanism 4, and then the multiple main reinforcing bars 20 are inserted into the headstock 11 through the positioning mechanism 3. The rotation speed of the headstock 11 and the moving speed of the apron 12 of the lathe 1 are then set, and the lathe 1 is started. The headstock 11 rotates the multiple main reinforcing bars 20 through the positioning mechanism 3. The rotating mechanism 4 moves laterally with the apron 12. The rotating mechanism 4, in conjunction with the rotation of the multiple main reinforcing bars 20, drives the multiple main reinforcing bars 20 to move laterally, pulling the multiple main reinforcing bars 20 from the head of the lathe 1 to the tail of the lathe 1. While multiple main reinforcing bars 20 rotate and move laterally, the coiled reinforcing bars 21 are continuously fed by the feeding mechanism 2. The coiled reinforcing bars 21 are then clamped and wound around the main reinforcing bars 20 by the welding mechanism 5 and the positioning mechanism 3. The welding point sensing mechanism 6 detects the intersection of the main reinforcing bars 20 and the coiled reinforcing bars 21 in real time. When the main reinforcing bars 20 and the coiled reinforcing bars 21 intersect, the welding mechanism 5 is energized to weld the intersection. When the main reinforcing bars 20 and the coiled reinforcing bars 21 do not intersect, the welding mechanism 5 is de-energized. This process is repeated to weld multiple intersections of the main reinforcing bars 20 and the coiled reinforcing bars 21 until the miniature steel cage is formed. In this technical solution, by monitoring the intersection of the main reinforcing bars 20 and the coiled reinforcing bars 21 in real time and controlling the on / off state of the welding mechanism 5, the welding of miniature steel cages with dense welding spacing is achieved, realizing the mass production of miniature steel cages. This has the beneficial effects of ensuring processing accuracy, improving processing efficiency, and facilitating control.

[0050] As described above, the positioning mechanism 3 includes:

[0051] The positioning post 31 is connected to the spindle box 11 at the middle of its bottom end, and multiple positioning holes 32 are symmetrically and through the positioning post 31.

[0052] The welding column 33 is fixedly connected to the top center of the positioning column 31, and the welding column 33 has multiple positioning grooves 34 corresponding to the multiple positioning holes 32.

[0053] Working principle: After connecting multiple main reinforcing bars 20 to the rotating mechanism 4, the multiple main reinforcing bars 20 are then inserted into multiple positioning holes 32. The multiple main reinforcing bars 20 enter the spindle box 11 through the multiple positioning holes 32. When the rotating mechanism 4 drives the multiple main reinforcing bars 20 to move laterally, the multiple main reinforcing bars 20 are pulled out from the spindle box 11 along the multiple positioning holes 32. The arrangement position of the multiple main reinforcing bars 20 is limited by the multiple positioning holes 32. The welding column 33 facilitates the continued winding and welding of the coiled reinforcing bars 21 along the multiple main reinforcing bars 20. The multiple positioning grooves 34 further limit the multiple main reinforcing bars 20, preventing deformation and displacement of the multiple main reinforcing bars 20 during the winding and welding process of the coiled reinforcing bars 21, thereby ensuring the welding effect of the miniature steel cage.

[0054] As described above, the rotating mechanism 4 includes:

[0055] The bracket 41 is fixedly connected to the slide box 12;

[0056] The limiting bearing 42 has its outer ring fixedly connected to the bracket 41, and the inner ring of the limiting bearing 42 has a plurality of symmetrical through-holes 43.

[0057] Working principle: During the welding of the miniature steel cage, the tail ends of multiple main reinforcing bars 20 are bent, and then the multiple main reinforcing bars 20 are passed through multiple connecting holes 43. Then, the multiple main reinforcing bars 20 are put into the spindle box 11 through multiple positioning holes 32. When the slide box 12 moves, the bracket 41 drives the limit bearing 42 to move laterally. The limit bearing 42 drives the multiple main reinforcing bars 20 with bent tail ends to move laterally through multiple connecting holes 43. The multiple main reinforcing bars 20 are pulled out from the head of the lathe 1 and moved to the tail of the lathe 1, and rotated in cooperation with the limit bearing 42.

[0058] As described above, the welding mechanism 5 includes:

[0059] A positioning bracket 51 is fixedly connected to the lathe 1, and a conductive frame 52 is provided on the positioning bracket 51. An insulating plate I 53 is provided between the conductive frame 52 and the positioning bracket 51. The conductive frame 52, the positioning bracket 51, and the insulating plate I 53 are connected by multiple bolts I 54, and each bolt I 54 is connected with an insulating pad I 55.

[0060] Welding roller 56 is elastically connected to the conductive frame 52, and the welding roller 56 is abutting against the welding column 33;

[0061] The output end of the welding machine 57 is electrically connected to the conductive frame 52, and the control board of the welding machine 57 is communicatively connected to the welding point sensing mechanism 6.

[0062] Working principle: During the welding of the miniature steel cage, the coiled ribs 21 are limited by the elastic connection between the welding rollers 56 and the conductive frame 52, so that the coiled ribs 21 are tightly attached to the welding column 33. Through the insulating plate I 53 and multiple insulating pads I 55, the positioning bracket 51 is not energized when the conductive frame 52 is energized. When the welding point sensing mechanism 6 detects that the main rib 20 has rotated to intersect with the coiled ribs 21, the output end of the welding machine 57 is energized, so that the conductive frame 52 and the welding rollers 56 are energized. Welding is performed by the welding rollers 56 abutting against the intersection of the main rib 20 and the coiled ribs 21. When the main rib 20 and the coiled ribs 21 are not intersecting, the output end of the welding machine 57 has no output, and the conductive frame 52 and the welding rollers 56 are not energized.

[0063] In the above scheme, the welding roller 56 is elastically connected to the conductive frame 52 in the following way:

[0064] Two slide rails are symmetrically arranged on the conductive frame 52. The welding roller 56 is rotatably connected inside the U-shaped plate 58. Slide grooves are opened on both sides of the U-shaped plate 58. The slide grooves are slidably connected to the slide rails. One end of the spring 59 is also connected to the bottom end of the U-shaped plate 58. The other end of the spring 59 is connected to the conductive frame 52.

[0065] Working principle: The spring 59, in conjunction with the conductive frame 52, applies an outward pushing force to the U-shaped plate 58, causing the U-shaped plate 58 to be pushed along the slide rail towards the welding column 33. This causes the welding roller 56 to abut against the welding column 33, making the coiled rib 21 tightly adhere to the welding column 33. When the main rib 20 and the coiled rib 21 intersect, they squeeze the welding roller 56 away from the welding column 33, causing the U-shaped plate 58 to be pushed in the opposite direction along the slide rail. This causes the spring 59 to compress and contract. After the main rib 20 and the coiled rib 21 intersect and are welded, the spring 59 drives the welding roller 56 to return to its original position.

[0066] As described above, the solder joint sensing mechanism 6 includes:

[0067] Multiple positioning blocks 61 are symmetrically connected to the positioning post 31, and the multiple positioning blocks 61 are respectively provided corresponding to the multiple positioning holes 32;

[0068] A photoelectric switch 62 is provided corresponding to the positioning block 61, and the photoelectric switch 62 is arranged parallel to the welding roller 56. The photoelectric switch 62 is communicatively connected to the control motherboard of the welding machine 57.

[0069] Working principle: The positioning column 31 drives multiple main ribs 20 to rotate, which in turn drives multiple positioning blocks 61 to rotate. Since multiple positioning blocks 61 are respectively set with multiple positioning holes 32, and the photoelectric switch 62 is set parallel to the welding roller 56, when the main rib 20 rotates to the point where it intersects with the coiled rib 21 on the side of the welding roller 56, the corresponding positioning block 61 corresponds to the photoelectric switch 62. Thus, the photoelectric switch 62 sends a control command to the control board of the welding machine 57, and the output end of the welding machine 57 is energized, thereby energizing the conductive frame 52 and the welding roller 56 to weld the intersection of the main rib 20 and the coiled rib 21.

[0070] As described above, an L-shaped frame 22 is also fixedly connected to the conductive frame 52. A connecting plate 23 is connected to the side end of the L-shaped frame 22. A guide plate 24 is provided on the connecting plate 23. An insulating plate II 25 is provided between the guide plate 24 and the connecting plate 23. The guide plate 24, the connecting plate 23, and the insulating plate II 25 are connected by multiple bolts II 26, and each bolt II 26 is connected with an insulating pad II 27. Wing plates 28 are also provided at both ends of the guide plate 24, and each wing plate 28 is provided with a guide hole 29.

[0071] Working principle: After the coiled rib 21 is fed by the feeding mechanism 2, it passes through the guide holes 29 of the two wing plates 28 and is clamped between the welding roller 56 and the welding column 33. The guide holes 29 of the two wing plates 28 guide the conveying path of the coiled rib 21 to avoid safety accidents caused by the coiled rib 21 tangling. The current of the conductive frame 52 is isolated by the insulating plate II 25 and the insulating pad II 27 to prevent the guide plate 24 and the coiled rib 21 from being energized when the conductive frame 52 is energized.

[0072] As described above, a handle 510 is also connected to the U-shaped plate 58, and a limiting buckle 511 is hinged to the conductive frame 52. The limiting buckle 511 engages with the handle 510 by deflection. The handle 510 facilitates the pushing of the U-shaped plate 58 by the operator when replacing the coil 21, while the limiting buckle 511 can limit and fix the handle 510 after it has pushed the U-shaped plate 58, making it easier for the operator to make adjustments.

[0073] As described above, the system also includes a cutting machine 7, which is mounted at the tail of the lathe 1 and is positioned corresponding to the rotating mechanism 4. After the miniature steel cage is welded, the tail of the miniature steel cage is cut by the cutting machine 7, thereby separating the miniature steel cage from the rotating mechanism 4.

[0074] In the above scheme, a contact switch 8 is fixedly connected to the tail end of the lathe 1. The slide box 12 slides against the contact switch 8, and the contact switch 8 is communicatively connected to the control main board of the welding machine 57. After the micro steel cage welding is completed, the slide box 12 moves to the tail end of the lathe 1 and abuts against the contact switch 8. The contact switch 8 sends a control command to the control main board of the welding machine 57, causing the welding machine 57 to shut down.

[0075] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made.
