[0002] like Figures 1 to 6 As shown, the steel cage 6 includes longitudinal steel bars 61 and annular stirrups 62, and the annular stirrups 62 are made by bending stirrups 63. When processing the steel cage 6, the stirrups 63 are welded and fixed to the lower longitudinal steel bars 61 in advance, and then the stirrups 63 are bent, and finally the upper longitudinal steel bars 61 are welded to the bent stirrups 63 (i.e., the annular stirrups 62) to complete the processing.

[0003] During the bending process of the stirrup 63, if the two sides of the stirrup 63 are not misaligned and are in the same longitudinal position (such as Figure 2 The rightmost stirrup 63, Figure 5 and Figure 6 As shown in the figure, when bending, the steel bar on the side of the rear bend will be placed on the steel bar on the side of the front bend, which may lead to stress concentration, unstable structure, inconvenience for welding, maintenance and other construction, and does not meet the requirements of bending. At present, the stirrups 63 usually need to be manually displaced, the dislocation consistency is poor, the labor intensity is high, and the structural stability is low. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] like Figures 7 to 12 As shown, the steel cage dislocation welding device of this embodiment includes a frame 1, on which a dislocation mechanism 2 and a welding mechanism 3 are provided. The welding mechanism 3 includes an intermediate electrode 31 and side electrodes 32 arranged on both sides of the intermediate electrode 31 in the transverse direction. The dislocation mechanism 2 includes at least one group of dislocation components 21 for moving the side edges of the U-shaped stirrups 63 in the longitudinal direction.

[0035] The steel cage staggered welding device of this embodiment, when in operation, places the steel cage 6 to be processed, in which the stirrups 63 and the lower longitudinal steel bars 61 have been pre-welded and fixed, on the frame 1, so that the intermediate electrode 31 is located in the middle of the U-shaped stirrups 63, and the staggered component 21 moves at least one side edge of the stirrups 63 longitudinally, so that the two sides of the stirrups 63 are staggered, and the side electrode 32 on one side cooperates with the intermediate electrode 31 to weld one side of the stirrup 63 to the longitudinal steel bars 61, and the side electrode 32 on the other side cooperates with the intermediate electrode 31 to weld the other side of the stirrup 63 to the longitudinal steel bars 61, to complete the staggered welding of the steel cage 6, and repeat the above steps to perform staggered welding on multiple stirrups 63 of the steel cage 6, and then bend the stirrups 63 after staggered welding to complete the forming of the steel cage 6. The steel cage dislocation welding device of the present embodiment has a simple structure, high production efficiency and high dislocation consistency. By setting the welding mechanism 3, the two sides of the dislocated stirrups 63 can be welded and fixed in time to prevent the dislocated stirrups 63 from rebounding or sliding and deflecting, resulting in incomplete dislocation. The structural stability of the steel cage 6 is high.

[0036] It should be noted that the longitudinal direction is the length direction of the longitudinal reinforcement 61 ( Figure 7 The horizontal direction is the direction perpendicular to the paper surface), and correspondingly, the horizontal direction is the direction perpendicular to the length direction of the longitudinal reinforcement 61 ( Figures 7 to 10 left and right directions in the image).

[0037] Furthermore, in this embodiment, two groups of dislocation components 21 are provided and are respectively located on the lateral sides of the middle electrode 31. Figure 7-10Misalignment components 21 are provided on both the left and right sides (in the figure), which can misalign both sides of the stirrup 63 simultaneously, with higher misalignment efficiency; at the same time, the misalignment distance on a single side is smaller, and the structural stability is higher.

[0038] Furthermore, in this embodiment, the misalignment component 21 includes a first pressing member 211 and a second pressing member 212 that can move longitudinally. The first pressing member 211 and the second pressing member 212 are arranged opposite to each other longitudinally. When misalignment is required, both the first pressing member 211 and the second pressing member 212 move towards the side of the stirrup 63, and the two cooperate to press the side of the stirrup 63. The pressing positions of the two misalignment components 21 on both sides of the stirrup 63 are错开 longitudinally to achieve misalignment of both sides of the stirrup 63, with a simple and stable structure.

[0039] Furthermore, in this embodiment, the misalignment component 21 further includes a mounting seat 213 that can move transversely. The first pressing member 211 and the second pressing member 212 are both arranged on the mounting seat 213. By moving the misalignment mounting seat 213 transversely, the transverse position of the misalignment component 21 can be adjusted to adapt to stirrups 63 of different specifications; after misalignment, the misalignment mounting seat 213 moves transversely to avoid interference and collision during subsequent welding and other operations; at the same time, the first pressing member 211 and the second pressing member 212 are arranged on the same mounting seat 213, so that the relative transverse positions of the first pressing member 211 and the second pressing member 212 remain unchanged, improving the consistency during multiple operations.

[0040] Furthermore, in this embodiment, a transverse movement driving member 214 and a guide rail 11 are provided on the frame 1. The mounting seat 213 is arranged on the guide rail 11, and the transverse movement driving member 214 is connected to the mounting seat 213 for driving the mounting seat 213 to move along the guide rail 11. When the mounting seat 213 reciprocates along the guide rail 11, deviation can be avoided, with a simple and reasonable structure and higher reliability. Among them, the transverse movement driving member 214 can be, for example, a cylinder, an oil cylinder or a lead screw nut mechanism, etc., which will not be elaborated here.

[0041] Furthermore, in this embodiment, the misalignment distance between both sides of the stirrup 63 longitudinally is d1, satisfying d1 > d, where d is the diameter of the stirrup 63. By ensuring d1 > d, that is, the misalignment distance between both sides of the stirrup 63 is greater than the diameter of the stirrup 63, when bending and forming, both sides of the stirrup 63 can be misaligned and bent smoothly without overlapping positions. Preferably, d < d1 < d + a, where a is the maximum allowable misalignment deviation of the stirrup 63, and a is slightly greater than 0, so that both sides of the bent stirrup 63 will not deviate too far, ensuring the strength of the steel cage 6.

[0042] Further, in this embodiment, the first pressing member 211 and the second pressing member 212 are respectively connected with a dislocation driving member 23. Among them, the dislocation driving member 23 can be an oil cylinder, a cylinder or an electric push rod, etc. When the output ends of the dislocation driving members 23 are fully extended, a gap d2 is formed between the first pressing member 211 and the second pressing member 212, satisfying d < d2 < (d + d1) / 2. By ensuring d < d2, that is, the gap formed between the first pressing member 211 and the second pressing member 212 is larger than the diameter of the stirrup 63, it is prevented that the first pressing member 211, the second pressing member 212 collide with the stirrup 63 and damage the equipment; by ensuring d2 < 1 / 2(d + d1), it is prevented that the gap between the first pressing member 211 and the second pressing member 212 is too large. After the two sides of the stirrup 63 are pressed, the position is not easy to determine and the dislocation effect is reduced. Preferably, d2 is slightly larger than d, which is beneficial to improving the consistency of the dislocation position and the dislocation effect is better.

[0043] Further, in this embodiment, the welding mechanism 3 further includes an electrode driving member 33, and the electrode driving member 33 is used to drive the side electrode 32 to move horizontally. By providing the electrode driving member 33, it is more convenient to move the side electrode 32. Among them, the electrode driving member 33 can be an oil cylinder, a cylinder or an electric push rod, etc., which will not be elaborated here.

[0044] Further, in this embodiment, a vertically adjustable steel bar support table 12 is provided below the intermediate electrode 31. During dislocation, the steel bar support table 12 supports the steel bar cage 6 to ensure stability during operation. By providing the vertically adjustable steel bar support table 12, the steel bar support table 12 can also adapt to stirrups 63 of various cross-sectional shapes.

Any person skilled in the art can make many possible changes and modifications to the technical solution of the present invention by using the methods and technical contents disclosed above, or modify it into an equivalent embodiment with equivalent changes.
