Description

Technical Field

[0001] This utility model relates to the field of steel rolling production technology, specifically a noise reduction device for steel rolling production. Background Technology

[0002] Steel rolling is a metal processing method that involves passing a metal billet between a pair of rotating rolls, using the pressure of the rolls to cause plastic deformation of the metal, thereby obtaining a product of the desired shape and size. Steel rolling is widely used in the production of various steel products, such as steel plates, steel pipes, and structural steel, and is one of the important links in the steel industry.

[0003] In the current steel rolling production process, steel cutting and conveying operations are required. In the traditional process, friction occurs between the steel and the conveying structure, resulting in significant friction noise that affects the overall working environment and makes it impossible for personnel to work in the environment. The traditional solution is to install sound insulation panels on the side of the conveying structure, but the semi-open structure makes its sound insulation and noise reduction effect insufficient. Utility Model Content

[0004] The purpose of this utility model is to provide a noise reduction device for steel rolling production, in order to solve the problem mentioned in the background art that in the current steel rolling production, the steel cutting and conveying operation requires friction with the conveying structure during the traditional process, resulting in large friction noise that affects the overall working environment and makes it impossible for personnel to work in the environment. The traditional method is to set a sound insulation plate structure on the side of the conveying structure, but the semi-open structure makes the sound insulation and noise reduction effect insufficient.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A noise reduction device for steel rolling production includes a main isolation cover. Side mounting strips are horizontally and symmetrically welded to both sides of the main isolation cover. Fixed through holes are evenly distributed on the top surface of each side mounting strip. Side through grooves are symmetrically distributed on both sides of the main isolation cover. An isolation sealing plate is vertically engaged with the inner side of each side through groove. A bottom locking groove is horizontally distributed on the bottom surface of the isolation sealing plate. An extrusion roller is horizontally engaged with the inner side of the bottom locking groove. Support shafts are horizontally and symmetrically fixed to both ends of the extrusion roller. The top of the side through groove is vertically... A vertical channel is provided, and a top-connecting spring is fixedly engaged on the inner side of the vertical channel. A limiting inner groove is symmetrically provided on the inner side of the vertical channel. A sound-insulating inner layer is fixedly provided on the inner side of the main isolation cover. A sound-absorbing inner layer is fixedly provided on the inner side of the sound-insulating inner layer. A limiting slot is symmetrically provided on the inner side of the side channel. Side limiting blocks are symmetrically welded to both sides of the isolation sealing plate. Limiting strips are symmetrically welded to both sides of the isolation sealing plate. A mating side layer is fixedly provided on one side of the isolation sealing plate.

[0007] In a preferred embodiment of the present invention, the bottom surface of the main isolation cover is open, and there are two mounting side strips. The two mounting side strips are fixedly and parallel to each other on two symmetrical sides of the main isolation cover, and the sides of the mounting side strips are fixedly and horizontally at the bottom of the side of the main isolation cover.

[0008] In a preferred embodiment of this utility model, there are multiple fixing through holes, and the multiple fixing through holes are arranged horizontally and equidistantly in a straight line at the center line of the top surface of the mounting side strip. The side through grooves are symmetrically opened at the bottom end of the center line of both sides of the main isolation cover, and the bottom end of the side through grooves extends through the bottom surface of the main isolation cover to the outside in an open shape.

[0009] As a preferred embodiment of the present invention: the top of the isolation sealing plate is vertically inserted into the inner side of the vertical channel, and the two sides of the isolation sealing plate are connected to the side opening end of the limiting slot. The bottom locking slot is horizontally opened at the center of the bottom surface of the isolation sealing plate, and the bottom surface of the extrusion roller extends to the outer side through the bottom opening of the bottom locking slot.

[0010] In a preferred embodiment of this utility model: the extrusion roller is connected to the inner side of the bottom clamping groove by the support shafts at both ends. The vertical groove and the side through groove are connected. There are multiple top springs, which are arranged in parallel at equal intervals. The bottom ends of the multiple top springs are clamped to the top surface of the isolation sealing plate. The limiting inner grooves are all set in pairs and are parallel and symmetrical to each other on the inner side of the vertical groove near both ends.

[0011] In a preferred embodiment of this utility model: the sound insulation inner layer is made of high-temperature resistant sound insulation material, the sound absorption inner layer is made of high-temperature resistant sound absorption material, the bottom end of the limiting slot extends through the bottom surface of the main isolation cover to the outside in an open shape, the side limiting blocks are symmetrically fixed in pairs on both sides of the isolation sealing plate near the top corner, and the side limiting blocks are correspondingly snapped into the inner side of the limiting inner groove, the limiting strip is vertically snapped into the inner side of the limiting slot, and the side layer and the sound absorption inner layer are made of the same material.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention horizontally connects the main isolation cover to the opening on the top surface of the steel rolling conveyor, positioning it at the top where noise is generated. Bolts pass through the fixing holes to secure the side strips. A top spring presses down the isolation plate, extending it from the vertical channel at the top to the inside of the side channel, finally connecting the bottom end to the top surface of the steel rolling mill. The bottom pressure roller presses against the top surface of the steel cutter, creating a stable pressure effect. Friction noise generated during the steel cutting conveyor movement is absorbed by the sound-absorbing inner layer, effectively isolating the noise. The additional layer of isolation from the main isolation cover further enhances the noise reduction effect. The enclosed sealing structure prevents noise from easily propagating outwards. Combined with the side layers, this creates comprehensive sound absorption and silencing. The integrated structure makes installation and use more convenient, and the combination of the positioning sealing structure and multiple sound insulation and absorption structures results in more comprehensive noise control.
