Description

Technical Field

[0001] This invention relates to the field of precast building components, and more particularly to an automated method and equipment for producing continuously bent and welded steel cages. Background Technology

[0002] With the development of the modern construction industry, the use of prefabricated building modules, such as prefabricated hollow columns, prefabricated wall panels, and prefabricated steel cages, is increasing in pursuit of higher construction efficiency. As market demand continues to grow, the production capacity gap for prefabricated hollow columns and prefabricated steel cages is widening, leading to increased labor costs and gradually becoming a bottleneck for the industry's development.

[0003] The structural design of steel cages has become quite mature, especially for polygonal and circular cross-section steel cages. However, if large-scale automated continuous production of steel cages is required, it is necessary not only to consider the structural strength of the steel cages, but also to focus on the design details to ensure they are suitable for automated production, whether the production equipment is easy to match, whether the production process can be simplified, and issues such as space occupation, material supply, and unloading of finished products. Among these, the most difficult problem to solve is how to achieve continuous automated production of continuous material supply, bending, and welding processes. Summary of the Invention

[0004] To overcome the above problems, the present invention provides an automated method and equipment for producing continuously bent and welded steel cages.

The steel cage includes main steel bars, stirrups, and tie bars, and includes a main steel bar support device, a stirrup bending device, a welding device, and a reinforcement device. The main steel bar support device is used for feeding the main steel bars and positioning and fixing multiple parallel main steel bars. The stirrup bending device, the welding device, and the reinforcement device are all rotatably connected to the main steel bar support device. The stirrup bending device is used for continuous feeding of the stirrups and bending the stirrups so that they abut against the outside of the main steel bars directly opposite the stirrup bending device. The welding device is used for welding and fixing the abutment points of the stirrups and the main steel bars. The reinforcement device is used for feeding tie bars from any specified direction and fixing the two ends of the tie bars to the stirrups or main steel bars through welding.

[0006] Preferably, the device also includes a stirrup pre-bending device located at the front end of the stirrup bending device. The stirrup pre-bending device is used to bend the stirrup to a specified angle before sending it into the stirrup bending device.

The rebar cage includes main rebars, secondary rebars, stirrups, and tie bars. The machine claw includes: a fixed base, an arc-shaped track, a welding torch, a fulcrum unit, and a clamping unit. The fixed base is used to connect to the rebar cage production equipment. The center of the arc-shaped track coincides with the axis of the main rebar or secondary rebar to be welded. The welding torch slides along the arc on the arc-shaped track, and the welding torch faces the axis of the main rebar or secondary rebar. The welding torch is slidably connected to the arc-shaped track in a direction perpendicular to the axis of the main rebar or secondary rebar. The fulcrum unit is used to hook the side of the main rebar or secondary rebar away from the welding torch when extended, providing a support force point. The clamping unit is used to push the stirrups on one or both sides of the welding torch toward the main rebar or secondary rebar so that the two abut against each other.

[0009] Preferably, the clamping unit is folded up towards the fixed seat so that the welding torch can be inserted into the steel cage for welding operations.

[0010] Preferably, it also includes a steering unit, which is disposed between the arc-shaped track and the fixed seat, and is used to rotate the arc-shaped track relative to the fixed seat to the opposite side, so that the welding torch can directly weld the two sides of the lap joint between the stirrup and the main reinforcing bar.

Several spaced tie rods are sequentially inserted into each of the surrounding parts in at least one direction, and the two ends of each tie rod are fixedly connected to the surrounding part or the main steel bar by welding. After completing the circumferential welding of all stirrups, stop feeding the stirrups and cut off the remaining stirrups; Release all the main reinforcing bars from their fixings and send out the completed reinforcing cage.

[0012] Preferably, the step involves rotating and continuously feeding stirrups around several main reinforcing bars, simultaneously bending the stirrups as they abut against adjacent main reinforcing bars; this also includes the following sub-steps: Before attaching the stirrups to the adjacent main reinforcing bars in sequence, the stirrups are pre-bent to the required angle or a continuous arc shape.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] See Figures 1 to 4 As an embodiment of the present invention, an automated method and equipment for producing continuously bent and welded steel cages are disclosed.

[0022] The production method includes the following steps: S1. Set and fix several main reinforcing bars 1 along the axis of the reinforcing cage; wherein, the fixing of the main reinforcing bars 1 can be either by directly fixing one or both ends of the entire main reinforcing bar 1 to the support, or by continuously feeding the main reinforcing bars 1 with continuous rollers while restricting the direction of movement and rotation of the main reinforcing bars 1. S2. Lap the first end of the stirrup onto any of the main reinforcing bars 1, and weld the lap joint to fix it. S3. Rotate around several main reinforcing bars 1 and continuously feed the stirrups, and while the stirrups are successively abutted against the adjacent main reinforcing bars 1, bend the stirrups; weld and fix the abutment points until the stirrups encircle all the main reinforcing bars 1 to form the stirrup loop 2. S4. Bend the stirrups and wrap them around the outside of several main reinforcing bars 1 until they reach the starting point 201 of the next adjacent wrapping part 2, forming the connecting part 3 of the stirrups; wherein the starting point 201 of the next adjacent wrapping part 2 is on any main reinforcing bar 1; the distance between the starting point 201 and the ending point 202 of the wrapping part 2 in the length direction of the main reinforcing bar 1 is greater than or equal to zero, so as to prevent the wrapping part 2 from interfering with the connecting part 3 and to leave sufficient welding space. S5. A number of spaced tie rods 5 are sequentially inserted in at least one direction in each of the surrounding parts 2, and the two ends of each tie rod 5 are fixedly connected to the surrounding part 2 or the main steel bar 1 by welding. S6. After completing the circumferential welding of all stirrups, stop feeding the stirrups and cut off the remaining stirrups; S7. Release all main reinforcing bars 1 from their fixings and send out the completed reinforcing cage.

[0023] In step S3, the stirrups are continuously fed around several main reinforcing bars 1 while rotating, and the stirrups are successively abutted against adjacent main reinforcing bars 1 while being bent; the steps also include the following: S31. Before attaching the stirrups to the adjacent main reinforcing bars 1 in sequence, the stirrups are pre-bent to the required angle or a continuous arc shape, and then the stirrups are bent and attached to the adjacent main reinforcing bars 1 in sequence; wherein the required angle is greater than or equal to the final bending angle of the stirrups at that point.

[0024] Using a pre-bending device to bend the stirrups at a certain angle helps reduce the workload, pressure, and amount of one-time deformation of the bending device, which in turn helps improve processing efficiency and reduces stress at the bending point and pressure on the main reinforcing bar 1, thus reducing subsequent deformation of the reinforcing cage.

[0025] Preferably, the procedure further includes the following steps: S11. Continuously and synchronously feed the main reinforcing bar 1 so that the bending and welding positions of the stirrups are as close as possible to the feeding port of the main reinforcing bar 1.

[0026] This step-by-step processing method is used to reduce the deformation problem that easily occurs when the welding position of the main reinforcing bar 1 is far from the fixed position. The closer the bending and welding position is to the fixed position of the main reinforcing bar 1, the smaller the deformation of the main reinforcing bar 1 will be when the stirrups are bent and joined.

[0027] Preferably, step S1 further includes the following sub-steps: S12. Several secondary reinforcing bars 4 are set and fixed along the axial direction of the reinforcing cage; wherein, the secondary reinforcing bars 4 are located inside the circumferential part 2 and are fixedly connected to the stirrups and / or tie bars 5 by welding. S13. Several secondary reinforcing bars 6 are set and fixed along the axial direction of the reinforcing cage; wherein, the secondary reinforcing bars 6 surround the inner side of the part 2 and are fixedly connected to the tie bars 5 by welding.

[0028] The form of the steel cage containing secondary steel bars 4 and secondary steel bars 6 is shown in Example 2 below.

[0029] This embodiment also includes an automated continuous bending and welding steel cage production equipment for specifically performing the above production method, including a main reinforcement support device 801, a stirrup bending device 802, a welding device 803, and a reinforcement device 804. The main reinforcement support device 801 is used for feeding the main reinforcement 1 and positioning and fixing multiple parallel main reinforcement 1. The stirrup bending device 802, welding device 803 and reinforcement device 804 are all rotatably connected to the main reinforcement support device 801.

[0030] There are at least two design methods for the rotating connection. For the production of longer steel cages, the main reinforcement support device 801 can be set horizontally, the main reinforcement 1 can be continuously rolled and fed, and the stirrup bending device 802, welding device 803 and reinforcement device 804 can be set on one side to feed and weld the steel cage of the continuously rotating main reinforcement support device 801.

[0031] In some cases, the main reinforcement support device 801 can remain stationary, while the stirrup bending device 802, welding device 803, and reinforcement device 804 are mounted on the front end of a multi-axis robotic arm on a slide rail, a movable circular track, or a gantry crane with a robotic arm. This allows for continuous, circular processing of the reinforcing cage, where the main reinforcement 1 can be either laid flat or erected. Any method that achieves the same technical effect falls within the protection scope of this solution.

[0032] In this embodiment, the stirrup bending device 802 is used for continuous feeding of stirrups and bending the stirrups so that they abut against the outside of the main reinforcing bar 1 directly opposite the stirrup bending device 802; specifically, a pressure roller directly squeezes the thinner stirrups around the main reinforcing bar 1, causing the stirrups to bend at a certain angle.

[0033] When the stirrups are thick, the stirrup bending device 802 can also use any existing mature steel bar bending device to bend the stirrups first, such as a mechanical bending machine fixed on a movable platform. After bending, the stirrups are pushed towards the main steel bar 1 for abutment and welding fixation.

[0034] The welding device 803 is used to weld and fix the joint between the stirrup and the main reinforcing bar 1. The welding device 803 can be an automatic welding gun 903 fixed at the front end of the multi-axis robotic arm, which can flexibly change its position and angle, or it can be a specially designed welding device with a structure optimized specifically for welding of reinforcing cages, so as to reduce the workload of parameter modification and path planning when adjusting the production type of reinforcing cage.

[0035] The reinforcing device 804 is used to feed the tie bars 5 from any specified direction and to fix both ends of the tie bars 5 to the stirrups or main reinforcing bars 1 by welding. The tie bars 5 can be pre-made finished tie bars 5, or they can be continuous reinforcing bars or other materials, which are cut after the feeding and welding are completed.

[0036] Preferably, the production equipment in this embodiment further includes a stirrup pre-bending device located at the front end of the stirrup bending device 802. The stirrup pre-bending device is used to bend the stirrup to a specified angle before sending it into the stirrup bending device 802 for a second bending and pressing it onto the main reinforcing bar 1.

[0037] Preferably, the reinforcing cage also includes secondary reinforcing bars 4 disposed between adjacent main reinforcing bars 1. The production equipment also includes a clamping device disposed around the welding device 803. The clamping device is used to push the stirrups toward the main reinforcing bars 1 or secondary reinforcing bars 4 so that the two abut against each other, so as to solve the problem that the secondary reinforcing bars 4 and the stirrups are easy to drift apart and difficult to weld. For the specific structure, please refer to Embodiment 4 below.

[0038] This embodiment also specifically discloses a continuous bending welded steel cage structure for automated production. This embodiment includes four main steel bars 1 distributed at the vertices of a square and parallel to each other, and a stirrup formed by bending a continuous steel bar. All fixed connection points are fixed by welding. Spot welding, or arc-shaped single-sided welding or double-sided welding around the bending point can be used.

[0039] For ease of demonstration, this scheme uses four main steel bars 1 as an example, which is also the style with the largest market demand and most suitable for large-scale automatic production. In actual production, the main steel bars 1 of the steel cage are also distributed in pentagons and hexagons. The stirrups can be polygonal or circular and fixed for different precast cavity columns.

[0040] The stirrup includes several circling portions 2 and connecting portions 3. The circling portion 2 includes a starting point 201 and an ending point 202. All starting points 201 are distributed at intervals along the length of the main reinforcing bar 1. The starting point 201 is fixedly connected to any main reinforcing bar 1. The circling portion 2 where the starting point 201 is located successively surrounds and abuts against four main reinforcing bars 1 until the ending point 202 of the circling portion 2 is fixedly connected to the main reinforcing bar 1 where the starting point 201 is located. The abutment of the circling portion 2 with any main reinforcing bar 1 is fixedly connected. The distance between the starting point 201 and the ending point 202 of each circling portion 2 along the length of the main reinforcing bar 1 is greater than or equal to zero, so as to prevent the circling portion 2 from interfering with the connecting portion 3 and to leave sufficient welding space.

[0041] The connecting part 3 is used to connect the end point 202 and the starting point 201 of the adjacent surrounding part 2. When the end point 202 and the starting point 201 are not on the same main steel bar 1, the connecting part 3 surrounds and abuts against several main steel bars 1 from the outside.

[0042] Two secondary reinforcing bars 4 are fixedly connected to one side of the surrounding part 2.

[0043] Each surrounding part 2 is provided with four tie rods 5, two horizontal and two vertical. The tie rods 5 are perpendicular to the length direction of the main steel bar 1, and both ends of each tie rod 5 are fixedly connected to the surrounding part 2. The tie units usually provided at both ends of the tie rods 5 can be expansion protrusions, bent steel bars, riveting sleeves, etc., which are used to be embedded in the mold shell 7 of the precast hollow column to tighten the mold shell 7 on both sides during the pouring of the hollow column and to counteract the stress caused by the concrete pressure to cause the mold shell 7 to expand outward.

[0044] Similarly, during rolling production, some independent tie rods can be welded at any position on the outside of the steel cage to pre-embed the formwork shell 7 to enhance the connection between the formwork shell 7 and the steel cage.

[0045] Preferably, all starting points 201 are evenly spaced along the length of the main reinforcing bar 1, which facilitates large-scale production by mechanical automation.

[0046] Preferably, the connecting part 3 surrounds and abuts against several main reinforcing bars 1 from the outside in the same direction as the direction from the starting point 201 to the ending point 202 of the surrounding part 2. This allows the reinforcing cage or production equipment to rotate in only one direction during the production process.

[0047] Preferably, the starting point 201 and the ending point 202 of each circling portion 2 are fixedly connected, that is, the starting point 201 and the ending point 202 are welded together to form a complete closed loop structure, thereby increasing the overall structural strength of the reinforcing cage. In some embodiments, this welding method can be used instead of welding the ending point 202 to the main reinforcing bar 1, that is, the ending point 202 is only welded to the starting point 201.

[0048] This invention features a steel cage structure design with continuously wound stirrups surrounding several main steel bars 1. Through its detailed fixed connection point layout and the rules for setting the starting point 201 and the ending point 202, it is convenient and flexible to design steel cages that are suitable for continuous production by automated equipment.

[0049] See Figure 5 and Figure 6 This is Embodiment Two of the present invention. Specifically, it discloses another type of reinforcing cage, different from Embodiment One. The reinforcing cage of this embodiment also includes eight secondary reinforcing bars 4 arranged parallel to the main reinforcing bars 1, and four secondary reinforcing bars 6. The feeding and fixing of the secondary reinforcing bars 4 and secondary reinforcing bars 6 are completed simultaneously with the feeding and fixing of the main reinforcing bars 1.

[0050] The secondary reinforcing bar 6 is fixedly connected to the two tie bars 5 on each of the surrounding parts 2.

[0051] This embodiment, through the structural design of tie rod 5, secondary reinforcement 4, and secondary reinforcement 6, facilitates strengthening the structural strength of the steel cage while enabling continuous automated production.

[0052] Preferably, the connecting part 3 is fixedly connected to the abutment of several main reinforcing bars 1 to increase the overall structural strength of the reinforcing cage.

[0053] Welding process applicable: For steel bars with a diameter of 10-19mm, lap arc welding (double-sided welding or single-sided welding) or rib welding is used.

[0054] The stirrup structure in this embodiment is a variation of the stirrup wrapping method in Embodiment 1. In this embodiment, the connecting part 3 is completely parallel to the main reinforcing bar 1, and all starting points 201 and ending points 202 are located on the same main reinforcing bar 1. Therefore, the stirrup structure is as follows: Figure 6 As shown.

[0055] See Figure 7 and Figure 8 This is Embodiment 3 of the present invention, and another variation of the stirrup wrapping method in Embodiment 1. Compared with Embodiment 2, in this embodiment, the starting point 201 of the stirrup wrapping portion 2 is distributed on different main reinforcing bars 1. Therefore, the connecting portion 3 wraps around the main reinforcing bar 1 for a longer section after the ending point 202, and then connects to the next starting point 201 along the length direction of the main reinforcing bar 1, forming as shown in the figure. Figure 7 The stirrup structure shown.

[0056] In other embodiments, the connecting portion 3 may also continuously bypass multiple main reinforcing bars 1 in an oblique wrapping manner as in the embodiment, connecting the end point 202 with the next starting point 201.

[0057] This embodiment also specifically discloses a hollow column, wherein a mold shell 7 is cast on the outside of the main steel bar 1 and the stirrups, and the two ends of the tie bar 5 are embedded inside the mold shell 7.

[0058] In some other embodiments, the stirrups can also be cast inside the mold shell 7 to serve as a tie, while further strengthening the structural strength of the mold shell 7. In this case, the two ends of the tie rod 5 can be straight steel bars, without the need to add expansion protrusions, bent steel bars, riveting sleeves or other structures to be pre-embedded in the mold shell 7.

[0059] Similarly, in some other embodiments, the main reinforcing bar 1 can also be cast inside the mold shell 7.

[0060] Preferably, the outer side of the main reinforcing bar 1 and the stirrup is pre-wrapped with at least one layer of fiber mesh, wire mesh or any combination thereof, and the tie bar 5 and the tie connector pass through the fiber mesh or wire mesh and are embedded in the outer formwork 7.

[0061] When fiber mesh or wire mesh is directly embedded in the mold shell 7, it serves to strengthen the structural strength of the mold shell 7.

[0062] When the fiber mesh or wire mesh is fine enough, or when it is covered with a waterproof material, it can be used as an inner mold for casting the formwork 7 and as a structural reinforcing bar for the column after final casting. When used as an inner mold, compared to the traditional method of casting the formwork 7 one side at a time, the inner mold made of fiber mesh or wire mesh or other materials, together with the matching outer mold, can cast all sides of the formwork 7 at once, thereby improving the overall structural integrity of the formwork 7 and strengthening the structural strength and sealing of the joints.

[0063] See Figure 9 This is Embodiment 4 of the present invention, which specifically discloses a tool head for welding steel cages. It can be installed at the front end of a multi-axis robotic arm or on a track device for displacement, so as to approach and align with the point to be welded.

[0064] The mechanical gripper of this embodiment can be used in the above-mentioned automated continuous bending and welding steel cage production equipment and method to further improve production efficiency and quality. The mechanical gripper includes at least: a fixed base 901, an arc-shaped track 902, a welding torch 903, a fulcrum unit 905, and a clamping unit 906; The mounting base 901 is used to connect to the rebar cage production equipment; The center of the arc-shaped track 902 coincides with the axis of the main reinforcing bar 1 or the secondary reinforcing bar 4 to be welded. The welding torch 903 slides along the arc on the arc-shaped track 902, and the welding torch 903 is facing the axis of the main reinforcing bar 1 or the secondary reinforcing bar 4. The welding torch 903 is slidably connected to the arc-shaped track 902 in a direction perpendicular to the axis of the main reinforcing bar 1 or the secondary reinforcing bar 4, which facilitates approaching and moving away from the welding point, and can be adapted to welding reinforcing bars of different diameters.

[0065] The fulcrum unit 905 is used to hook the main reinforcing bar 1 or the secondary reinforcing bar 4 away from the welding torch 903 when extended, providing a support point. The clamping unit 906 is used to push the stirrups on one or both sides of the welding torch 903 toward the main reinforcing bar 1 or the secondary reinforcing bar 4 so that the two abut against each other.

[0066] Preferably, the clamping unit 906 is folded up towards the fixing seat 901 for the welding gun 903 to extend into the steel cage for welding operations, and for welding and fixing the secondary steel bars 6 and the reinforcing bars inside the steel cage.

[0067] Preferably, it also includes a steering unit 904, which is located between the arc-shaped track 902 and the fixed seat 901. The steering unit 904 is used to rotate the arc-shaped track 902 relative to the fixed seat 901 to the opposite side, so that the welding torch 903 can directly weld the two sides of the lap joint between the stirrup and the main reinforcing bar 1 in an arc shape.

The processor can be a Central Processing Unit (CPU), or other general-purpose processors, digital signal processors (DSPs), application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The general-purpose processor can be a microprocessor or any conventional processor. The processor is the control center of the testing equipment, connecting various parts of the testing equipment through various interfaces and lines.

[0069] Storage devices can be used to store computer programs and / or modules. Processors implement various functions of terminal devices by running or executing computer programs and / or modules stored in the storage device and by accessing data stored in the storage device. A storage device may primarily include a program storage area and a data storage area. The program storage area may store the operating system, applications required for at least one function, etc.; the data storage area may store data created based on the use of the terminal device, etc. Furthermore, storage devices may include high-speed random access memory, and may also include non-volatile memory, such as hard disks, RAM, plug-in hard disks, smart media cards (SMC), secure digital cards (SD cards), flash cards, at least one disk storage device, flash memory device, or other volatile solid-state storage devices.

Based on this understanding, all or part of the processes in the above embodiments of the present invention can also be implemented by a computer program instructing related hardware.
