[0002] In the production of prefabricated components, it is usually necessary to embed steel bars in concrete to increase the strength of the prefabricated components. Generally, the production of steel bar components requires the transverse steel bars to be welded together with multiple bent longitudinal steel bars at a certain angle. Steel bar components usually require a steel bar bending machine to bend the longitudinal steel bars into different shapes, and then a welding machine to weld the longitudinal steel bars and transverse steel bars together at an angle. The existing welding machines and bending machines have complex structures, and the two machines occupy a large area. In addition, manual labor or a transmission mechanism is required to transport the bent steel bars to the welding position of the welding machine.

[0003] In addition, the existing integrated steel bar bending and welding device is usually of assembly line type, with the welding and bending mechanisms distributed at different workstations. A conveying mechanism is required to alternately move the steel bars to the welding and bending mechanisms, or alternately move the welding and bending mechanisms to the positions of the longitudinal steel bars for operation. A corresponding clamping mechanism is also required, and each movement requires repositioning and clamping, which is inefficient. In addition, there are also the above-mentioned defects such as complex structure, large footprint and low production efficiency. Utility Model Content

[0030] like Figures 1 to 6 As shown, the steel bar bending and welding device of this embodiment includes a first mounting seat 1, a welding mechanism 3 for welding the first steel bar 91 and the second steel bar 92, and a bending mechanism 4 for bending the first steel bar 91. The welding mechanism 3 includes a welding drive 31, a fixed electrode 32 and a movable electrode 33. The welding drive 31 and the fixed electrode 32 are arranged on the first mounting seat 1, the movable electrode 33 is connected to the welding drive 31 and is arranged opposite to the fixed electrode 32, and the bending mechanism 4 is arranged on the welding drive 31.

[0031] During the operation, the first steel bar 91 and the second steel bar 92 are placed crosswise on the fixed electrode 32, and the welding drive 31 drives the mobile electrode 33 to move toward the fixed electrode 32, and the mobile electrode 33 cooperates with the fixed electrode 32 to press the first steel bar 91 and the second steel bar 92 and complete the welding. After the welding is completed, the mobile electrode 33 still presses the first steel bar 91 and the second steel bar 92 between the mobile electrode 33 and the fixed electrode 32. At this time, the bending mechanism 4 bends the first steel bar 91 to complete the bending. The bending mechanism 4 of the steel bar bending welding device of this embodiment is arranged on the welding drive 31, and the welding and bending of the first steel bar 91 and the second steel bar 92 can be completed without moving the steel bar or welding and bending mechanisms. The structure is simple and compact, the footprint is small, and the production efficiency is high; by the relative arrangement of the fixed electrode 32 and the mobile electrode 33, the steel bar can be pressed during welding to ensure the welding quality, and the clamping mechanism can be set up separately during the subsequent bending operation to achieve the effect of clamping the steel bar, which can simplify the device structure and operation steps, and has high production efficiency. The steel bar bending and welding device of this embodiment has the advantages of simple and compact structure, small footprint and high production efficiency.

[0032] Optionally, two movable electrodes 33 are provided, one connected to the positive pole of the power supply and the other connected to the negative pole, so that the steel bar bending and welding device of this embodiment can realize dual-point simultaneous welding; optionally, the movable electrode 33 and the fixed electrode 32 are respectively connected to the positive and negative poles to improve the welding quality and make the welding more stable.

[0033] Furthermore, in this embodiment, a first placement portion 321 for placing the first steel bar 91 and a second placement portion 322 for placing the second steel bar 92 are provided on the fixed electrode 32. The first steel bar 91 is placed in the first placement portion 321, and the second steel bar 92 is placed in the second placement portion 322, so that the first steel bar 91 and the second steel bar 92 are at an angle to each other, which can adapt to the processing of steel bar components with different angle requirements.

[0034] Furthermore, in this embodiment, a plurality of second placement portions 322 are arranged at intervals along the transverse direction, and the groove between two adjacent second placement portions 322 forms a first placement portion 321, and the first placement portion 321 extends toward the side where the movable electrode 33 is located. Multiple first steel bars 91 can be placed in the groove of the first placement portion 321 to achieve welding and bending of one second steel bar 92 and multiple first steel bars 91. The transverse direction is the length direction of the second steel bar 92, and the groove between two adjacent second placement portions 322 forms the first placement portion 321, which can ensure that the second steel bars 92 and the first steel bars 91 placed therein are arranged in a horizontal and vertical cross arrangement, meeting the molding requirements. During operation, the first steel bar 91 is placed in the first placement portion 321, and then the second steel bar 92 is placed on the second placement portion 322. Because the first placement portion 321 extends toward the side of the movable electrode 33, when the second steel bar 92 is placed on the first placement portion 321, the first steel bar 91 placed in the first placement portion 321 is located above the second steel bar 92. Therefore, during the bending process, the first steel bar 91 can be bent with the welding intersection as the force fulcrum, and the first steel bar 91 will not fall out of the groove of the first placement portion 321, which is more stable.

[0035] Furthermore, in this embodiment, the second placement portion 322 is a hook-shaped structure, which is simple and easy to use.

[0036] Furthermore, in this embodiment, a second mounting seat 2 is also included, the second mounting seat 2 is connected to the welding driver 31, the mobile electrode 33 and the bending mechanism 4 are arranged on the second mounting seat 2, the second mounting seat 2 is provided with a first guide rod 51 on both sides of the welding driver 31, and the first mounting seat 1 is provided with a first guide hole 11 that matches the first guide rod 51. Through the connection between the second mounting seat 2 and the welding driver 31, during the welding process, the bending mechanism 4 moves with the movement of the welding driver 31 and also moves toward the first steel bar 91, and the structure is compact; the provision of the first guide rod 51 is conducive to the stability of the movement process of the mobile electrode 33 driven by the welding driver 31, and prevents deviation, and the welding is more accurate.

[0037] Furthermore, in this embodiment, the bending mechanism 4 includes a bending drive member 41 and a bending assembly 42 for bending the first steel bar 91, the bending drive member 41 is arranged on the welding drive member 31, and the bending assembly 42 is arranged on the bending drive member 41. The bending mechanism 4 approaches the first steel bar 91 as the welding drive member 31 moves, and then the bending drive member 41 drives the bending assembly 42 to complete the bending operation, which can reduce the stroke and size of the bending drive member 41, and has a simple and compact structure.

[0038] Furthermore, in this embodiment, the bending assembly 42 includes a bending member 421 and a bending seat 422 for mounting the bending member 421, and the bending seat 422 is connected to the bending driving member 41. The bending member 421 is used to bend the first steel bar 91, and the bending member 421 frequently contacts the steel bar and needs to be replaced frequently. By mounting the bending member 421 on the bending seat 422, it is easy to replace the bending member 421.

[0039] Furthermore, in this embodiment, the bending member 421 is a bending roller shaft, which can reduce friction, reduce the force required to be output by the bending drive member 41, and also increase the service life of the bending assembly 42.
