detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

As shown in the accompanying drawings, the noise-reducing and environment-friendly steel bar cutting device of the present utility model includes a cutting machine main body, and a noise-reducing protective cover is arranged on the cutting machine main body. The noise reduction protective cover is arranged outside the main body of the cutting machine to absorb and reduce the sharp noise generated by the main body of the cutting machine during the cutting operation.

The noise reduction protective cover includes a bottom plate 1 on which an arc-shaped casing 2 is hinged, and a support bar 3 is arranged at the inner lower part of the arc-shaped casing 2 . The main body of the cutting machine is placed on the bottom plate and placed under the inside of the arc-shaped casing. A wear-increasing rubber pad is provided on the bottom plate 1 to prevent the main body of the cutting machine from shifting. The hinged arc-shaped cover can be opened and closed relative to the bottom plate, so as to facilitate the adjustment of the cutting machine inside. A visual window 11 and an operation port 12 are arranged on the noise reduction protective cover. Visible window 11 observes cutting operation conveniently, and operating port can facilitate the entry and exit of steel bars.

Side plates 4 are arranged on the left and right sides of the upper part of the arc-shaped casing 2, and a Z-shaped folded honeycomb hole plate 5 is arranged under the front part of the arc-shaped casing 2. The Z-shaped folded honeycomb hole plate 5 is connected with the side plate 4 and the curved cover. A muffler cavity is formed between the shells 2, and a muffler mechanism is arranged in the muffler cavity. The noise pulse enters the sound-absorbing cavity from the honeycomb holes on the Z-shaped folded honeycomb hole plate 5 and is silenced by the sound-absorbing mechanism of the sound-absorbing cavity. Further, the Z-shaped folded honeycomb hole plate 5 is a glass steel plate, and the honeycomb holes are evenly distributed on the glass steel plate. FRP has the characteristics of light weight but hard, non-conductive, high temperature resistance, stable performance, and high mechanical strength. It can prevent sparks generated during steel bar cutting from igniting the noise reduction protective cover, and has the function of safety and fire prevention.

The noise elimination mechanism includes a high-temperature rock wool board layer 6, a sound-absorbing sponge layer 7, a PET plastic layer 8 and a wood wool board layer 9. The wood wool board layer 9 is closely attached to the inner wall of the arc-shaped casing 2, and the number of the PET plastic layer 8 is two Two layers of PET plastic layers are vacuumed, the outer PET plastic layer is bonded to the inner wall of the wood wool layer through inorganic glue, the high-temperature rock wool layer 6 is bonded to the inner wall of the PET plastic layer, and the sound-absorbing sponge Layer 7 is set on the inner wall of the high temperature rock wool slab. Hollow tubes 10 are evenly spaced on the inner surface of the sound-absorbing sponge layer 7 , and a sound-absorbing film is arranged inside the hollow tubes 10 .

The sound-absorbing sponge is made of melamine foam, which has unique sound-absorbing, heat-insulating, flame-retardant, high-temperature-resistant, light-weight and other comprehensive properties. When in the cavity, it is partially absorbed by the sound-absorbing sponge. Rock wool board is a new type of thermal insulation, flame-proof and sound-absorbing material. The artificial inorganic fiber processed by high-temperature melting has the characteristics of light weight, small thermal conductivity, heat absorption and non-combustibility. At the same time, its material is soft and can be Prevent the PET plastic layer from being too hard to produce cracks. Vacuum sound insulation is an effective means of sound insulation. Since the construction site will produce collisions during handling or cutting, vacuuming between two layers of PET plastic layers can prolong the service life and prevent fragmentation.
