Description

Technical Field

[0001] The invention relates to a straightening device, in particular to a straightening device for ribbed steel bars. Background Art

[0002] Steel bars are an indispensable material in construction projects. There are many types of steel bars, such as ribbed steel bars. Ribbed steel bars refer to steel bars with protrusions on them. This type of steel bar is mainly used to strengthen its direct bonding with cement. There are two types of ribbed steel bars: hot-rolled and cold-rolled. The hot-rolled type is commonly known as threaded steel bars, which are generally used in houses, roads and other projects, while the cold-rolled type is mainly used in cast-in-place concrete structures and has better stability. When the ribbed steel bars are bent, they need to be straightened.

[0003] When the straightening device is in use, in order to facilitate the inspection of the straightening wheel, the straightening wheel is set on the outside, and the exposed straightening wheel is easily damaged. If a cover is set for the straightening wheel, it needs to be flipped open during maintenance, which is not convenient. In addition, since the straightening wheel is in contact with the ribbed steel bar, iron filings and foreign matter on the surface of the ribbed steel bar are attached to the wheel groove of the straightening wheel. The iron filings and foreign matter accumulated for a long time will affect the straightening effect of the straightening wheel on the ribbed steel bar. Since there are several straightening wheels, the iron filings and foreign matter attached to the wheel groove are not convenient to clean. Summary of the Invention
