Problems solved by technology

[0002] At present, the production of stirrups in the construction industry requires straightened steel bars. After the steel bars are straightened, they are manually fed and bent. The labor intensity is high and the production efficiency is low. Later, mechanical equipment is also used for operation. Although bending and hydraulic bending reduce the labor intensity of the operator, there are still problems such as low production efficiency, easy wear of steel bars, high mechanical power, and high energy consumption. Steel bar straightening machines are often used to straighten steel bars, and It can remove the scale on the surface of the steel bar, and the steel bar straightening frame is the main component of the steel bar straightening machine
However, the side of the common straightening frame is set as a disc, and the centrifugal force of the straightening is too large, which increases the wear and tear on the straightening wheel and is easy to be damaged. life

Abstract

The invention relates to an improved rebar straightening frame. A straightening frame body is a rectangular frame body of which the interior is hollow, and short edges at the two ends are connected with a first connection pipe and a second connection pipe correspondingly. Straightening wheel devices penetrate through milling discs to be fixedly installed on the two sides of the interior of the straightening frame body. Reinforcement pressing plates are fixedly installed on the upper side and the lower side of the straightening frame body. Fixing rods penetrate through the straightening frame body and are fixedly installed on the straightening frame body through first nuts. The milling discs are hexagonal, are embedded in the side surfaces of the straightening frame body and are internallyprovided with milling disc grooves and fixing holes. The improved rebar straightening frame is high in practicality and simple in structure, discs on the side surfaces of the straightening frame are replaced with the hexagonal milling discs, the straightening centrifugal force is reduced, the concentricity of rebar straightening and the rotation speed are improved, and meanwhile, the straighteningframe body is reinforced.
