Description

Rebar Cutting Device The present invention relates to a rebar cutting device, and more specifically, to a rebar cutting device capable of accurately and stably cutting rebar by moving at the same speed and in the same direction as a plurality of rebars supplied at a constant speed when cutting rebar to a set length. Generally, reinforcing steel is a construction material made by shaping steel into a rod to primarily support tensile forces, and it is one of the mechanical structures treated with great importance in fields such as civil engineering and architectural engineering. At this time, the above reinforcing bar is mainly formed using carbon steel as the main material and is combined with concrete subjected to compressive force to form a reinforced concrete structure. In addition, the above reinforcing bars are divided into deformed reinforcing bars formed from steel bars with protrusions such as ribs and nodes on the surface, and round reinforcing bars formed from steel bars with a smooth, circular cross-section without protrusions. In order to use reinforcing bars in various industrial sites, it is necessary to cut reinforcing bars produced to the same specifications into specific lengths according to the required length. In order to supply reinforcing bars to a cutting machine, two workers had to manually spread out the reinforcing bars one by one and then supply them to the cutting machine, which consumed an excessive amount of time for the cutting process and not only failed to effectively provide reinforcing bars of the required length, but also caused the problem of increased labor costs due to the increased number of required personnel. Furthermore, since workers have to manually lift and transport the cut rebar one by one, additional work is required even after the cutting is finished, leading to reduced productivity. Additionally, safety accidents frequently occur during the cutting or transportation process due to worker negligence, resulting in worker injuries. Moreover, when measuring the length of reinforcing bars, there was a problem of reduced productivity due to the complexity of the work and the unnecessary waste of manpower caused by measuring and marking the length to be cut on each reinforcing bar with a tape measure, or measuring and cutting one sample with a ruler, then using the cut sample to make it the same length as other reinforcing bars, and then cutting it with a cutting machine. Meanwhile, although an automated device for aligning rebar using a stepped automatic sorting feeder was developed, it was difficult to consider the problem of reduced productivity and economic efficiency to be resolved, as the rebar aligned in this stepped automatic sorting feeder would get tangled again during the process of being transported to a conveyor belt, requiring a worker to manually correct it, which resulted in wasted manpower and a significant amount of time. Therefore, a method to resolve these problems is required.
