Bending device for trial production of hot-rolled ribbed steel bars and using method of bending device

Abstract

The invention discloses a bending device for trial production of hot-rolled ribbed steel bars and a using method of the bending device. The bending device comprises a working box, first fixing boxes are symmetrically arranged on one side of the working box, first two-way lead screws are rotatably connected to the interiors of the first fixing boxes, first sliding blocks are symmetrically connected to the outer sides of the first two-way lead screws in a threaded mode, and the first sliding blocks and the first fixing boxes are in sliding connection. The bending device has the beneficial effects that belt wheels are additionally arranged, the two belt wheels drive two first two-way lead screws to rotate at the same time, the first two-way lead screws drive a moving box to move through the first sliding blocks, a rotating mechanism is additionally arranged, first bevel gears drive rotating rods to rotate through second bevel gears, the rotating rods drive moving plates to rotate, the moving plates slide in limiting grooves, when the moving plates rotate, worms are driven to rotate through the limiting grooves, and by additionally arranging straightening rollers, straightening treatment on steel bars is achieved.

Description

technical field [0001] The invention relates to the technical field of hot-rolled ribbed steel bars, in particular to a bending device for trial production of hot-rolled ribbed steel bars and an application method thereof. Background technique [0002] Rebar is a common name for hot-rolled ribbed steel bars. There are two commonly used classification methods for rebar: one is classified by geometric shape, which is classified or typed according to the cross-sectional shape of the transverse rib and the distance between ribs, and the other is classified by performance. (level), according to the strength level (yield point / tensile strength), the rebar is divided into 3 grades. In the existing hot-rolled ribbed steel bar trial production, it is necessary to bend the hot-rolled ribbed steel bar, but now Some bending devices are inconvenient to straighten the hot-rolled ribbed steel bar in advance, which affects the bending efficiency, and it is not convenient to fix the steel ba...
