Description

Technical Field

[0001] The utility model relates to the technical field of steel bar processing, in particular to a steel bar straightening and welding integrated machine. Background Technique

[0002] The steel bar straightening device is indispensable in construction projects. Firstly, it can ensure the project quality, ensure the straightness of steel bars to enhance the structural stability and bearing capacity, improve the precision, and ensure the bonding force between concrete and steel bars. Secondly, it can improve the construction efficiency, save manpower and time, and facilitate the cooperation with automated equipment to achieve assembly line operation. Moreover, it can reduce costs, reduce material waste and extend the service life of steel bars. Finally, it can meet the requirements of different projects, can be adjusted for various specifications of steel bars, and can play a role in different construction environments, providing a strong guarantee for the smooth progress of construction projects.

[0003] Currently, the steel bar straightening equipment mainly relies on two rows of grooved wheels distributed up and down to straighten the steel bars through pressing over a certain distance. In addition, manual tools can also be used for fine adjustment. However, at the feeding end, due to the large degree of distortion of the steel bars, it is often difficult to smoothly enter the grooved wheels. And the steel bars to be straightened are often used ones with insufficient length and need to be welded before they can be used again. Usually, welding is carried out after straightening, which undoubtedly adds an extra process. If welding can be directly carried out after the steel bars are straightened, a large amount of time will be saved. Content of the Utility Model

A gear is meshed above the toothed ring, and the gear is driven by a motor fixed above the guiding cylinder. A welding frame is connected to the side of the toothed ring close to the straightening box, and a welding torch is arranged on one side of the welding frame. The welding torch is driven by a cylinder fixed on the welding frame.

[0015] Based on the above features, the welding frame drives the welding torch to rotate with the toothed ring, and can perform all-round welding around the steel bar, ensuring the uniformity and quality of the welding. The cylinder drives the welding torch, which can quickly adjust the position and welding pressure of the welding torch and is suitable for welding steel bars of different specifications.

A straightening cylinder 9 is detachably provided on the straightening plate 7. A connecting plate 10 is integrally formed at the edge of the end of the straightening cylinder 9. Between the baffle 4 and the straightening box 2, between the straightening plate 7 and the processing table 1, and between the connecting plate 10 and the straightening plate 7, they are all connected by a number of bolts. The connecting plate 10 is integrally formed at the edge of the end of the straightening cylinder 9, which increases the structural strength and stability of the straightening cylinder 9, and can be installed and fixed without damaging the structure of the straightening cylinder 9, so that it is not easy to deform or damage during the working process. The bolt connection is firm and reliable and is convenient for disassembly and replacement.

[0025] Combined with the attached Figure 1 , the straightening cylinder 9 is made of hard metal material. The diameter of the straightening cylinder 9 is larger than the diameter of the limiting hole 5. The inner wall of the end of the straightening cylinder 9 away from the connecting plate 10 is an arc surface. The hard metal straightening cylinder 9 has high hardness and wear resistance, can withstand the friction and pressure of the reinforcement during the straightening process, and prolongs the service life of the straightening cylinder 9. The larger diameter of the straightening cylinder 9 can provide a larger space for the bent reinforcement for preliminary correction, reduce the resistance when the reinforcement enters the limiting hole 5, improve the smoothness of the feeding, and the arc surface can reduce the wear of the straightening cylinder 9 during the straightening process of the reinforcement, and the straightening force is more evenly distributed, and the straightening effect is better.

[0026] Combined with the attached Figure 1 , attached Figure 3 , through holes for cooperating with the straightening cylinder 9 are provided on the straightening plate 7.

Insert the end of the steel bar to be straightened into the straightening cylinder 9, and make it pass through the through hole and the limiting hole 5 and enter between the straightening grooved wheels 6 on the straightening frame 3. If the steel bar is relatively long, its end finally enters the guiding cylinder 8. Use an external device to pull the steel bar to move. The part with a larger bend of the steel bar is pre-straightened under the action of the port of the straightening cylinder 9, enabling it to move smoothly. Subsequently, it moves to between the straightening grooved wheels 6 for precise straightening. After the steel bar is straightened, pull it back to align the end of the steel bar with the welding torch 15. Put another straightened steel bar to be welded into the guiding cylinder 8 and make the ends of the two contact each other. Adjust the position of the welding torch 15 through the cylinder 16 so that it can weld the joint of the two steel bars. Turn on the motor 13. The motor 13 drives the gear 12 to rotate. The gear 12 meshes with the toothed ring 11 to rotate. The toothed ring 11 drives the welding torch 15 to rotate around the steel bar through the welding frame 14, thereby realizing uniform welding of the joint of the steel bars. At this time, pull the steel bar from one end and take it out. During the use of the steel bar straightening and welding integrated machine, the straightening frame 3 and the straightening cylinder 9 can be removed and replaced with appropriate models according to needs.
