Description

Technical Field

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

[0002] In the field of building pile foundation construction, the reinforcing cage is usually welded together with multiple main bars and spiral reinforcement. Its working principle is similar to that of the longitudinal reinforcement in concrete columns. It is mainly used to bear the axial tensile force of the structure, compensate for the low tensile strength of concrete, and effectively restrain the concrete of the pile body.

[0003] Currently, when welding rebar cages, it is usually necessary to use a ring-shaped support frame to arrange multiple main reinforcing bars in a ring according to the design diameter, and then spirally wrap the reinforcing bars around the outside of the main reinforcing bars before welding. However, most existing support frame structures are relatively fixed and are usually only suitable for rebar cages of a single diameter. When welding rebar cages of different diameters, it is often necessary to change the entire set of support fixtures, which is not only cumbersome and affects production efficiency, but also indirectly increases manufacturing costs. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a rebar cage welding device to solve the problem that the existing rebar cage welding device requires to replace the entire welding device when welding rebar cages of different specifications, which makes the operation cumbersome and affects the production efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. By rotating the adjusting component inside the rotating cylinder, multiple fixed components can be simultaneously driven to slide along the slide groove, thereby flexibly adjusting the support diameter formed by the enclosure of each fixed component. This allows the same device to quickly adapt to steel cages of different specifications without the need to change the support tooling, making operation simple. At the same time, the first driver drives the rotating cylinder to rotate, which can coordinate the spiral winding and welding operations of the steel reinforcement, effectively improving production efficiency and reducing equipment investment costs.

[0013] Furthermore, the adjusting member includes:

[0014] A rotating block is rotatably disposed inside the rotating cylinder and is coaxially arranged with it;

[0015] Several sliders are respectively slidably engaged in several of the aforementioned grooves and connected to the corresponding fixing members;

[0016] Several drive rods, each having one end rotatably mounted on one of the aforementioned sliders and the other end rotatably mounted on the rotating block;

[0017] A limiting member is provided on the rotating cylinder and connected to the rotating block, used to rotate the rotating block or to limit its movement.

[0018] Furthermore, the limiting member includes a worm gear fixed to one side of the rotating block and coaxially arranged therewith, and a worm rotatably disposed on the rotating cylinder and meshing with the worm gear.

[0019] Furthermore, one end of the worm gear passes through the rotating cylinder and is provided with an adjustment tube.

[0020] Furthermore, the fixing member includes a fixing seat fixed to the slider, a fixing block slidably engaged with the fixing seat, and a screw threadedly connected to the fixing seat. The screw is rotatably connected to the fixing block, and the fixing block abuts against the surface of the reinforcing bar.

[0021] Furthermore, V-shaped grooves are provided on the opposite side of both the fixing seat and the fixing block, and the reinforcing bars are located in the two V-shaped grooves.

[0022] Furthermore, an adjusting block is provided at the end of the screw.

[0023] Furthermore, the rotating cylinder has notches corresponding to the plurality of sliding grooves.

[0038] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0039] To make the objectives, technical solutions, and beneficial effects of this invention clearer, the technical solutions of this invention are further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0040] like Figure 1-4As shown in the figure, an embodiment of the present invention proposes a rebar cage welding device, comprising: two mounting plates 10 arranged opposite to each other, with the rebar cage located between the two mounting plates 10; two rotating cylinders 20, each having multiple sliding grooves 21, and rotatably mounted on the two mounting plates 10 respectively, wherein one of the mounting plates 10 is provided with a first driver 30 (using a motor or electric motor in the prior art) for connecting to one of the rotating cylinders 20 to drive it to rotate; a fixing unit, comprising multiple fixing members 40 slidably mounted on the multiple sliding grooves 21 and an adjusting member 50 rotatably mounted within the rotating cylinder 20, wherein the adjusting member 50 is connected to the multiple fixing members 40 for adjusting the spacing between the fixing members 40; and a base 60, wherein one of the mounting plates 10 is slidably mounted on the base 60, and the base 60 is provided with a movable member 70 for pushing the mounting plate 10 to move.

[0041] In this embodiment, during use, the spacing between the fixing components 40 is first adjusted according to the design diameter of the steel cage to be processed. Specifically, the operator rotates the adjusting component 50 inside the rotating cylinder 20, which simultaneously drives multiple fixing components 40 to slide outward or retract inward along the slide groove 21, so that the support diameter formed by the fixing components 40 matches the distribution circle diameter of the main reinforcement of the steel cage. Compared with the traditional method of changing the tooling as a whole for the support frame, this device can quickly switch the support size by simply rotating the adjusting component 50. The operation is simple and quick, effectively shortening the preparation time before welding steel cages of different specifications.

[0042] After adjustment, one end of each main reinforcing bar is sequentially fixed to a fixing member 40 on one of the rotating cylinders 20, and the other end of each main reinforcing bar is correspondingly fixed to a fixing member 40 on the other rotating cylinder 20, so that all the main reinforcing bars are arranged in a ring and supported by the two rotating cylinders 20. Since the two mounting plates 10 are set opposite each other and position the main reinforcing bars from both ends of the reinforcing cage, the axial straightness and circumferential uniformity of the main reinforcing bars are ensured throughout the welding process, thereby improving the forming quality of the reinforcing cage.

[0043] Subsequently, one end of the wrapping rebar is fixed to the end of the main rebar, and the first driver 30 is activated. The first driver 30 drives the rotating cylinder 20 connected to it to rotate. Since the two ends of each main rebar are fixed by the fixing parts 40 on the two rotating cylinders 20 respectively, when one rotating cylinder 20 rotates, it drives the other rotating cylinder 20 to rotate synchronously through the main rebar. The wrapping rebar wrapped around the outside of the main rebar is then continuously pulled and tightly wrapped around the outside of the main rebar arranged in a ring. The operator can then use a welding torch or an automatic welding device to weld at the contact point between the main rebar and the wrapping rebar.

[0044] After welding is completed, the adjusting component 50 is reversed to loosen the main reinforcement of the fixing component 40. Then, the movable component 70 pushes one of the mounting plates 10 to slide outward along the base 60, so that the distance between the two mounting plates 10 is greater than the length of the formed steel cage, providing sufficient space for the steel cage to be removed. The formed steel cage can then be removed from the device.

[0045] Specifically, such as Figure 3 As shown, in this embodiment, the adjusting member 50 includes: a rotating block 51, rotatably disposed within the rotating cylinder 20 and coaxially arranged therewith; a plurality of sliders 52, each slidably engaged in a plurality of sliding grooves 21 and connected to the corresponding fixing member 40; a plurality of driving rods 53, each having one end rotatably disposed on a plurality of sliders 52 and the other end rotatably disposed on the rotating block 51; and a limiting member disposed in the rotating cylinder 20 and connected to the rotating block 51, used to rotate the rotating block 51 or to limit its movement.

[0046] In practical use, since the rotating block 51 and the rotating cylinder 20 are coaxially arranged, and one end of each drive rod 53 is rotatably connected to the rotating block 51 and the other end is rotatably connected to the corresponding slider 52, when the rotating block 51 rotates, it will push each slider 52 to slide synchronously along the slide groove 21 through the drive rod 53, so that each slider 52 drives the fixed part 40 connected to it to move radially along the slide groove 21, thereby realizing that the support diameter formed by all the fixed parts 40 expands or shrinks synchronously. This not only makes the operation convenient and efficient, but also ensures that the movement of each fixed part 40 is consistent, so that each main reinforcement can always maintain a uniform ring distribution, thus ensuring the forming accuracy of the steel cage.

[0047] Specifically, such as Figure 2-3 As shown, in this embodiment, the limiting component includes a worm gear 54 fixed to one side of the rotating block 51 and coaxially arranged therewith, and a worm 55 rotatably disposed on the rotating cylinder 20 and meshing with the worm gear 54. By rotating the worm 55, the worm gear 55 drives the meshing worm gear 54 to rotate. Since the worm gear 54 is fixed to one side of the rotating block 51 and the two are coaxially arranged, when the worm gear 54 rotates, it drives the rotating block 51 to rotate synchronously within the rotating cylinder 20, thereby driving the fixing component 40 to move radially along the slide groove 21, thus realizing the synchronous expansion or contraction of the support diameter formed by all the fixing components 40. At the same time, the cooperation between the worm gear 54 and the worm 55 has a self-locking characteristic, and it automatically locks after adjustment, without the need for additional limiting structures. This effectively ensures that the fixing component 40 maintains a stable clamping state during the welding process, improving welding quality and operational safety.

[0048] In addition, to facilitate adjustment of the worm gear 55, one end of the worm gear 55 passes through the rotating cylinder 20 and is provided with an adjustment tube 56. The outer contour of the adjustment tube 56 is polygonal, so as to facilitate manual gripping or tool clamping; at the same time, it also has polygonal holes, such as hexagonal holes, inside, so as to facilitate rotational adjustment using a corresponding hexagonal wrench.

[0049] Specifically, such as Figure 4 As shown, in this embodiment, the fixing member 40 includes a fixing seat 41 fixed to the slider 52, a fixing block 42 slidably engaged with the fixing seat 41, and a screw 43 threadedly connected to the fixing seat 41. The screw 43 is rotatably connected to the fixing block 42, and the fixing block 42 abuts against the surface of the reinforcing bar. When the reinforcing bar is placed between the two fixing seats 41, the screw 43 is rotated, causing it to rotate and move on the fixing seat 41, thereby driving the fixing block 42 at its end to move until the fixing block 42 abuts against the surface of the reinforcing bar, pressing and fixing the reinforcing bar. The rotating cylinder 20 has notches 22 corresponding to the plurality of sliding grooves 21, so that the reinforcing bar can be placed between the two fixing seats 41 through the notches 22.

[0050] Furthermore, V-shaped grooves 45 are provided on the opposite side of both the fixing seat 41 and the fixing block 42, and the reinforcing bars are located in the two V-shaped grooves 45. The three-point contact positioning of the reinforcing bars through the two V-shaped grooves 45 can not only accommodate main reinforcing bars of different diameters, but also has a good self-centering effect, so that the reinforcing bars are always kept in the center position of the fixing seat 41, thereby ensuring the uniform distribution of each main reinforcing bar when arranged in a ring.

[0051] In addition, to facilitate the adjustment of the screw 43, an adjusting block 44 is provided at the end of the screw 43. By rotating the adjusting block 44, the screw 43 can be rotated, thereby achieving quick fixing and disassembly of the reinforcing bar. In this embodiment, the adjusting block 44 can be configured as a handwheel or a hexagonal head structure to facilitate manual tightening or operation with tools.

[0052] Specifically, such as Figure 1As shown, in this embodiment, the movable component 70 includes a lead screw 71 rotatably mounted on the base 60, and a second driver 72 mounted on the base 60 and connected to one end of the lead screw 71. A slide 73 is provided at the bottom of the mounting plate 10, and the slide 73 is threadedly connected to the lead screw 71. By activating the second driver 72 (using a motor or electric motor as in the prior art), the lead screw 71 rotates within the base 60, and the slide 73 moves along the axial direction of the lead screw 71. This allows for rapid adjustment of the distance between the two mounting plates 10. On the one hand, this provides operating space for removing the formed rebar cage; on the other hand, it allows the distance between the two mounting plates 10 to be steplessly adjusted according to the needs of rebar cages of different lengths, further expanding the applicability of the device and enabling it to flexibly adapt to the processing of rebar cages of various lengths.

[0053] Furthermore, the inner side of the base 60 is provided with a slide rail 74, and the slide block 73 is slidably connected to the slide rail 74. Through the sliding connection between the slide block 73 and the slide rail 74, the mounting plate 10 can move smoothly and stably on the base 60, thereby reducing friction and resistance during movement, thus improving transmission efficiency and reducing noise.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
