Internal stiffening loop thrust unit for CNC steel reinforcement cage molding machine

Abstract

The invention discloses an internal stiffening loop thrust unit for a CNC steel reinforcement cage molding machine. The structure of the thrust unit comprises a turntable, wherein a screw rod is inserted into the center of the turntable; one end of the screw rod is connected with a driving mechanism; the driving mechanism is fixed on one side face of the turntable; the other side face of the turntable is fixed with a plurality of reinforcement passing pipes and a plurality of guide shafts; internal stiffening loops are clamped in inner rings of the plurality of reinforcement passing pipes; the other end of the screw rod is fixedly connected on one side face of a push rack; the push rack is positioned on the other side of the turntable and passes through the plurality of guide shafts; and the other side face of the push rack is pressed against the side faces of the internal stiffening loops. The thrust unit overcomes the defects in the prior art, replaces manual push of the internal stiffening loops, ensures safety of operators and enhances production efficiency. An adjusting arm can move in an adjusting hole of a loop pushing plate and adapt to the production of steel reinforcement cages with different specifications, realizes automatic feeding of the internal stiffening loop, reduces the labor intensity, and enhances the production efficiency. The thrust unit has the advantages of simple structure, convenient maintenance, stable work, energy conservation and low processing cost.

Description

technical field [0001] The invention relates to a numerically controlled reinforcement cage forming machine, in particular to an inner stiffening hoop pushing device of the numerically controlled reinforcement cage forming machine. Background technique [0002] The CNC reinforcement cage forming machine is a special equipment for automatic welding of reinforcement cages. The reinforcement cage is formed by welding a helical stirrup to the columnar outer circle formed by multiple main reinforcements; the inner circle of the reinforcement cage is also An inner stiffening hoop is provided, and the inner stiffening hoop is welded and fixed to the inner ring of the reinforcement cage by a plurality of hoops at intervals, and the inner stiffening hoop plays a role of supporting the reinforcement cage. [0003] The processing technology of the prior art for welding and fixing the inner stiffening stirrups to the inner ring of the steel cage is: when the stirrups and the main bars a...
