Straightening and cutting machine ПРА499 is designed for decoiling, straightening and dimensional cutting of hot-rolled round steel of smooth and periodic profile with a diameter of 5 to 16 mm. class A-I; A-II; Ac-II and A-III according to GOST 5781-82. Straightening of a wire with a diameter of 4 mm is allowed according to GOST6727-80 in the manufacture of an additional tool at the request of the customer for an additional fee. The machine is equipped with decoiler and receiving devices. The receiving device has a measuring mechanism, which allows to obtain blanks of the required length.
The straightening of the material is carried out in the guide bushings and in the correct frame in all planes by its multiple transverse plastic bending by blanks, which are installed in the nests of the fast-rotating regular frame. To adjust the gap between the lower and upper feed rollers, depending on the size of the material section, the axis of the rollers is made eccentric. The correct frame is driven by an electric motor through a V-belt drive.
