Description

Technical Field

[0001] The present invention relates to the technical field of steel bar framework welding, and specifically to a processing, welding and forming device for concrete precast components. Background Art

[0002] In modern construction processes, in order to improve construction efficiency, prefabricating building components using concrete is a common method. It is a common construction technique to prefabricate building components in advance and then transport them to the construction site for assembly. The main structure of concrete precast components is mainly divided into two parts. First is the steel structure inside the concrete component, and then the concrete structure wrapped around the steel structure.

[0003] The steel structure is used to improve the overall structural strength of the component, and the steel structure is often set according to the shape of the component. The steel structure is formed by welding, and then a formwork is used to pour concrete on the steel structure to form a concrete structure wrapped around the steel structure. After curing and treatment, the overall production of the precast component is completed.

[0004] Therefore, the steel structure not only relates to the overall structural strength of the precast component, but also the cooperation between the steel structure and the concrete structure plays a role in restraining the concrete structure, improving the bonding between the concrete structure and the steel structure. The steel structure is mainly composed of main bars, stirrups and distribution bars. By welding each other, the main bars, stirrups and distribution bars form a steel bar framework. Such a steel bar structure is not only simple in structure but also has good support.

[0005] When the steel bar framework is under construction, it needs to be distributed and welded. At present, it mainly relies on manual labor to fix the positions of the main bars and distribution bars, and then manually weld the welding points. However, this method requires manual adjustment of the positions of the distribution bars or stirrups. Not only is the welding operation relatively cumbersome, the operation volume of workers is relatively large, but also the welding technology requirements for workers are relatively high during the welding process.

[0006] Due to the technical problems existing in manual welding, automatic welding equipment has emerged at present. For example, a steel bar component welding device disclosed in the patent with publication number CN119057323A can weld the overlapping section of the first steel bar component and the second steel bar component horizontally and convert the overlapping section to be welded longitudinally. Welding and feeding are carried out alternately. Such a welding structure is mainly based on welding a rectangular steel bar framework. Firstly, it cannot weld a circular steel bar cage as required. Secondly, during the welding process, it can only weld along a straight line and cannot splice the completed welded framework. In view of this, in-depth research on the above problems has led to the generation of this case. Summary of the Invention

Detailed implementation manners

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0052] Please refer to Figures 1-9 , the present invention provides an implementation scheme: in the processing of modern precast concrete components, the steel bar skeleton is an important part to increase the structural strength of concrete components. However, in the current stage of welding the steel bar skeleton, the automatic welding machine mainly welds based on a rectangular steel bar frame. Firstly, it cannot weld a circular steel bar cage as required. Secondly, during the welding process, it can only weld along a straight line and cannot splice the completed welded frame.

[0053] Embodiment 1: To solve the above problems, according to the attached drawings of the specification Figures 1-9 it can be known that the present application discloses a processing and welding forming device for precast concrete components, including a chassis 1. The chassis 1 is a support frame made of steel structure. The steel structure chassis 1 adopts an H-shaped steel welded frame. Based on the steel structure chassis 1 as the basic support frame, an operation box 2 is arranged on the chassis 1. A welding channel 21 is arranged on the operation box 2. The operation box 2 installed on the chassis 1 serves as the core processing unit. A guiding and adjusting assembly 3 is arranged below the welding channel 21. A fixed control seat 42 is arranged on the guiding and adjusting assembly 3. The above guiding and adjusting assembly 3 is used to adjust the linear movement of the fixed control seat 42 to realize the function of using the movement of the fixed control seat 42 to traction the main steel bar of the reinforcement;

[0054] According to the attached drawings of the specification Figures 1-9 it can be known that a traction head end fixator 4 is arranged on the above fixed control seat 42. A control assembly 5 is also arranged on the fixed control seat 42. The control assembly 5 is connected to the traction head end fixator 4. The traction head end fixator 4 is connected to the head end of the main steel bar of the reinforcement. The control assembly 5 drives the traction head end fixator 4 to rotate, and then drives the main steel bar of the reinforcement to rotate. Thus, while the main steel bar of the reinforcement performs axial movement under the action of the guiding and adjusting assembly 3, the stirrups and distribution bars are circumferentially distributed on the surface of the main bar by the rotation of the main steel bar of the reinforcement, and then welded by a welding mechanism 6;

[0055] According to the attached drawings of the specification Figures 1-9It can be seen that a welding mechanism 6 is provided on the above-mentioned operation box 2.

Through the action controller 62, the movement of the welding machine 63 can be controlled, enabling the welding machine 63 to contact the connection points of the main bars with the stirrups and distribution bars, thus realizing the welding of the stirrups and distribution bars to the main bars;

[0056] The action controller 62 is a three-axis motion fine-tuning platform installed on the steel bar frame. The welding machine 63 uses the resistance welding method to perform intermittent welding on the intersection points of the main bars and the stirrups.

[0080] Prefabricated frame positioning and docking. The supporting bench lifts the prefabricated steel bar frame and inserts it into the splicing groove. The welding corrector adjusts the height of the guiding support through the lifting guide groove. The new and old main steel bars are end-to-end staggered and inserted through the staggered arrangement mechanism, with a spacing ≥ 2 times the diameter of the steel bar. The hydraulic pin completes the temporary fixation;

[0081] Continuous welding of the splicing seam: The electric welding machine switches to the continuous welding mode and performs multi-layer and multi-pass welding along the splicing seam. The current of the first layer is 280A, and it decreases by 20% layer by layer thereafter. The parameter adaptive system dynamically adjusts the welding speed to 0.1 - 0.5 m / min;

[0082] Reset and cyclic operation: Remove the temporary fixation mechanism. The rotation adjustment component resets to the initial angle. The supporting conveyor belt synchronously extends to support the lengthened overall frame, and continue with the next section of welding or remove the finished product.

[0083] In summary, it can be generally known that during the entire processing process, the coordinated movement of the guiding adjustment component and the rotation adjustment component realizes the composite processing mode of linear welding and circular forming. The multi-station clamping system of the traction head end fixator cooperates with the precise angle control of the indexing rotating shaft to ensure the equal-spacing steel bar arrangement accuracy of the circular steel cage. The spatial positioning mechanism of the welding corrector and the azimuth adjustment function of the rotating platform break through the limitation of traditional equipment that can only perform linear welding and realize the modular splicing and manufacturing of complex steel bar skeletons.
