Reinforcing steel bar bending machine for building road and bridge

Abstract

The invention discloses a reinforcing steel bar bending machine for building road and bridge. The reinforcing steel bar bending machine for building road and bridge comprises a fixed case, a fixing unit, a bending rotating unit, a fixing supporting unit, antifriction units, a reinforcing steel bar back end fixing unit, a pulley fixing unit, a metal slag absorption unit and a straw fixing unit. A round slot is formed in the upper end of the fixed case, the bending rotating unit and the fixing supporting unit are separately arranged in the round slot of the fixed slot, the fixing unit is arranged at the upper end of a fixed round block in the bending rotating unit, a reinforcing steel bar supporting block is arranged on the right back side of the upper end of a fixed disc in the fixing and supporting unit, the reinforcing steel bar back end fixing unit is arranged at the let end of the reinforcing steel bar supporting block, at least four antifriction units are uniformly arranged at the lower end of the fixed disc, moving and fixing mechanisms are arranged, so that it is convenient to move and fix the bending machine and a twisting device is arranged, so that it is convenient to bend a reinforcing steel bar at a fixed angle.

Description

technical field [0001] The invention relates to the technical field of bending machines, in particular to a steel bar bending machine for building roads and bridges. Background technique [0002] The so-called steel bar bending machine is one of the steel bar processing machines. The working mechanism is a horizontal working disc rotating on a vertical axis. The steel bar is placed for processing, the supporting pin is fixed on the machine tool, the center pin and the bending pin are installed on the working disc, and the bending speed is stable and accurate. In addition, the conversion speed can be automatically controlled by electricity, and the brake can ensure the bending angle. The central shaft is replaceable for easy maintenance. Intelligent control can be adopted. A steel bar bending machine is provided which can flexibly adjust the bending angle of steel bars, and will be widely used in the future. [0003] However, the existing steel bar bending machine for con...

Problems solved by technology

[0003] However, the existing steel bar bending machine for construction, road and bridge engineering is huge in equipment, which is not conducive to the migration work. The traditional steel bar bending method is used to bend the steel bar. For the steel bars with large quantity, large diameter and high strength, the traditional steel bar bending The labor intensity of the machine is high, and it cannot be intelligently controlled by numerical control, so the efficiency is low, and it is obviously not competent
