Suitable for steel bending devices of different diameters

Abstract

The invention discloses a bending device suitable for steel bars of different diameters. The bending device comprises a working table and supporting legs, and the top of the working table is provided with a boss, a first through hole, a groove and a fixing block; a rotary shaft is arranged in the first through hole, a second driving mechanism is arranged at the bottom end of the rotary shaft, and a rotating table is arranged at the top end of the rotary table; a connecting rod is arranged in the groove, a supporting table is arranged at the top end of the connecting rod, and a guiding cylinder, a positioning rod and a first driving mechanism are arranged on the supporting table; the guiding cylinder is provided with a second through hole and a heating wire, the positioning rod is connected with the supporting table through a thread, and the positioning rod can move into the groove; and the first driving mechanism comprises an output shaft, the axis of the output shaft and the axis of the second through hole are on the same line, the connecting rod is arranged on the fixing block, and the connecting rod can make contact with the rotating table. According to the bending device suitable for the steel bars of the different diameters, the width of a track formed by the boss and the rotating table can be adjusted so as to achieve bending of the steel bars of the different diameters, production cost is saved, and meanwhile production efficiency is improved.

Description

technical field [0001] The invention relates to a steel bar processing equipment, in particular to a steel bar bending device suitable for different diameters. Background technique [0002] Rebar refers to the steel used for reinforced concrete and prestressed reinforced concrete, whose cross section is circular, sometimes square with rounded corners. Including plain round bars, ribbed bars, twisted bars. Steel bars for reinforced concrete refer to the straight or coiled steel used for reinforced concrete reinforcement. Its shape is divided into two types: smooth round steel bar and deformed steel bar. The delivery state is straight bar and coiled round. Light round bars are actually small round bars and round bars of ordinary low carbon steel, and deformed bars are ribbed bars on the surface, usually with 2 longitudinal ribs and transverse ribs evenly distributed along the length. The shape of the transverse rib is spiral, herringbone and crescent. Expressed in millimete...
