[0002] The axis length of the prestressed small box girder of the expressway is generally 25m~40m. The horizontal distribution steel bars of the top plate, inclined web plate and bottom plate of the box girder are generally 10mm diameter threaded steel bars. In order to reduce the loss of raw materials, the steel bars are generally in the form of coils when entering the site, and are processed into finished steel bars of a specific length by a straightening and cutting machine. The traditional processing method is that the raw materials need to be manually assisted in pulling and placing after passing through the straightening and cutting machine. The operation is difficult and not conducive to ensuring construction safety. After the finished products of one length are completed, they need to be transferred completely before the production of another type of steel bars can continue, and the production efficiency is not high.
