Noise reduction and cutting device capable of adjusting length of steel bars

Abstract

The invention discloses a noise reduction and cutting device capable of adjusting the length of steel bars. The noise reduction and cutting device comprises an upper fixed plate, a lower fixed plate,clamping rods, guide carrier rollers, a rotating disc, noise reduction devices and a cutting device. The two sides of the upper surface of the lower fixed plate are in bolted connection with the clamping rods. A rotating shaft penetrates the circle center position of each guide carrier roller. The clamping rods are connected to the rotating shafts. Side plates are arranged on the inner walls of the two sides of each noise reduction protection cover. A wood-wool plate layer is closely attached to the inner wall of each noise reduction protection cover. A PET plastic layer located on the outer side is bonded to the inner wall of each wood-wool plate layer through inorganic glue. A high-temperature rock wool plate layer is bonded to the inner wall of each PET plastic layer located on the inner side. A sound absorption sponge layer is arranged on the inner wall of each high-temperature rock wool plate layer. Hollow pipes are evenly arranged on the inner surface of each sound absorption sponge layer at intervals. An adjusting rod is fixedly connected to the middle end of the upper fixed plate. A cutting blade is connected to an output shaft of a cutting motor. A scrap collection box isarranged at the position, under the cutting blade, of the lower fixed plate. Bases are fixedly connected to the lower surface of a lower fixed block.

Description

technical field [0001] The invention relates to the field of steel bar cutting devices, in particular to a noise reduction cutting device capable of adjusting the length of steel bars. Background technique [0002] Reinforcement refers to steel for reinforced concrete and prestressed reinforced concrete, which is circular in cross-section and sometimes square with rounded corners. Including plain round bars, ribbed bars, twisted bars. Steel bars for reinforced concrete refer to the straight or coiled steel used for reinforced concrete reinforcement. Its shape is divided into two types: smooth round steel bar and deformed steel bar. The delivery state is straight bar and coiled round. When steel bars are used on construction sites, they often need to be cut off, which requires a steel bar cutting machine. The existing cutting machines are generally fixed manually, which not only has high labor intensity, but also has low cutting accuracy. And it will generate a lot of noise...

Problems solved by technology

When steel bars are used on construction sites, they often need to be cut off, which requires a steel bar cutting machine. The existing cutting machines are generally fixed manually, which is not only labor-intensive, but also has low cutting accuracy.

And it will produce a lot of noise when cutting, which will affect the lives of nearby residents
