Device for regulating sectional dimension of stirrup box of steel reinforcement framework machine

Abstract

The invention discloses a device for adjusting the section size of the stirrup box of a steel bar frame machine, which comprises a screw mechanism arranged along the direction of the cross section of the stirrup box and a chain transmission mechanism for driving the screw mechanism. The two ends of the screw mechanism are fixed on the bottom of the stirrup box. The amplitude-modulating screw of the frame and the nut connected to the movable frame of the stirrup box form a spiral pair, and the chain transmission mechanism is installed on the bottom frame of the stirrup box to drive the amplitude-modulating screw to rotate, so that the movable frame of the stirrup box moves with the nut. Two sets of amplitude modulation lead screws of the screw mechanism are symmetrically arranged in parallel, with the same thread direction, and are respectively connected with the sprockets of the chain transmission mechanism. A slide rail may be provided at the joint between the nut of the screw mechanism and the movable frame of the stirrup box, or two nuts on the same amplitude-modulating screw may be arranged at intervals to support the movable frame of the stirrup box and guide it to move. The invention can adjust the width of the stirrup box, that is, the cross-sectional size according to the size of the spiral continuous stirrup, which facilitates the storage of the stirrup.

[0002] The forming of the steel bar skeleton adopts a special seam welding machine to weld multiple round or square main bars and spiral stirrups wound on the main bar. When the steel bar frame is formed, a driving system is required to drive the main bar and the formed frame relative to the traction system. Rotate to realize the winding of stirrups on the main reinforcement. This forming method improves the mechanization level of steel skeleton forming to a certain extent, but there is still a gap with the energy-saving and environmentally friendly production process advocated by the country, and for different specifications of polygonal cross-section steel The skeleton is also difficult to shape with this method

In addition, the manufacturing process of the spiral stirrup on the steel frame directly affects the quality and production efficiency of the steel frame. When the existing steel frame seam welding machine makes the steel frame, it needs to be welded while winding the spiral stirrup. If the spiral stirrup is pre-processed Compression "spring shape" can save the forming time of the steel frame; the existing steel frame seam welding machine has a single style of steel frame, which can only surround the outer circumference of the main bar. If the spiral stirrup is pre-processed into a spiral shape, the stirrup The method of placing the main reinforcement first and then inserting it can produce a steel skeleton with a staggered network structure of spiral stirrups. This new reinforcement skeleton forming method requires special reinforcement skeleton forming equipment. The key part of this equipment is the spiral continuous stirrup pressure storage. And orderly release device - stirrup box
