Metal bar straightening device for constructional engineering

Abstract

The invention discloses a metal bar straightening device for constructional engineering, and relates to the technical field of construction machinery. The metal bar straightening device comprises a base, a bearing table, a straightening assembly and a driven straightening wheel, when an air heater works, external air can be heated and then conveyed into a preheating box to preheat metal bar bodies to be straightened, so that the plasticity of the metal bar bodies is enhanced; and the air heater achieves circulation of air in the preheating box through an air return pipe and an air outlet pipe, energy consumed by the air heater for heating external air in a reciprocating mode is saved, and a first straightening wheel and a second straightening wheel can slide along a driving shaft to adjust the distance between the first straightening wheel and the second straightening wheel, so that the metal bar straightening device is suitable for metal rod bodies of various specifications, the use range of the device is expanded, a rust removal assembly can polish rust spots on the surfaces of the metal bar bodies after the metal bar bodies are straightened, multiple rust removal polishing discs are fixed to the inner wall of the rust removal barrel assembly through fastening bolts, the rust removal abrasive discs can be detached and replaced after being used for a period of time, and the whole rust removal barrel assembly does not need to be replaced.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a metal rod straightening device for construction engineering. Background technique [0002] Straightening machine is a device for straightening metal profiles, bars, pipes, wires, etc. The straightening machine uses straightening rollers to squeeze the bar to change the straightness. Generally, there are two rows of straightening rollers with different numbers. , There is also a two-roll straightening machine, which relies on the angle change of the two rolls (concave in the middle, hyperbolic roll) to straighten materials with different diameters. The main types are pressure straightening machine, balance roller straightening machine, shoe rolling straightening machine, rotary reverse bending straightening machine, etc. The position of the roller is at a certain angle to the direction of movement of the straightened product, two or three large The first is the ...
