Reinforcing steel bar shredding machine

Abstract

The invention relates to waste steel treatment equipment, in particular to a reinforcing steel bar shredding machine. The reinforcing steel bar shredding machine comprises a base and a driving mechanism, wherein a box body is arranged on the base, a cutter shaft is arranged in the box body, the cutter shaft is rotationally connected with two side plates of the box body, a plurality of claw-shaped moving cutters are installed on the cutter shaft, a spacer sleeve is arranged between every two adjacent moving cutters, and rectangular cutter blocks are fixedly connected between cutter teeth of every two adjacent moving cutters; and an inclined fixed cutter plate is arranged on the outer side of the cutter shaft, the two ends of the fixed cutter plate are fixedly connected with the two side plates of the box body respectively, the lower end of the fixed cutter plate is in a comb tooth shape, a tooth groove of the fixed cutter plate is rectangular, the tooth groove is matched with cutter teeth of the movable cutter, and the cutter shaft is driven by the driving mechanism. The reinforcing steel bar shredding machine is simple in structure, low in cost, high in production efficiency, capable of cutting steel bars with different diameters and free of material leakage.

Description

technical field [0001] The invention relates to scrap steel processing equipment, in particular to a steel bar shredder. Background technique [0002] Scrap rebar is a renewable resource that needs to be recycled, but steel mills require cutting 10-12 cm lengths before they can be recycled into the furnace for steelmaking. At present, steel bar cutting machines are generally of double-shaft structure, with high cost, low output, high failure rate, and short service life. Small machines are scrapped after processing thousands of tons, and can produce 5-6 tons in 8 hours a day. Large-scale shredders have high production costs. Although they can produce tens of tons a day, the blades need to be replaced after they are worn out and cost hundreds of thousands of yuan. In the case of steel bars of different thicknesses, they cannot be used normally at all, and thin steel bars may leak. , It is necessary to sort the scrap steel bars, which increases the cost.

Problems solved by technology

At present, the steel bar cutting machine generally adopts a double-shaft structure, which has high cost, low output, high failure rate, and short service life. Small machines are scrapped after processing thousands of tons, and can produce 5-6 tons in 8 hours a day.

Large-scale shredders have high production costs. Although they can produce tens of tons a day, the blades need to be replaced after they are worn out and cost hundreds of thousands of yuan. In the case of steel bars of different thicknesses, they cannot be used normally at all, and thin steel bars may leak. , it is necessary to sort the scrap steel bars, which increases the cost
