Non-metal sound barrier die

Abstract

The invention provides a non-metal sound barrier die, which comprises a plate body, wherein a layer of galvanized steel sheet is coated on the plate body, four right angles of the plate body are reinforced by angle steel, the two sides of the plate body are provided with side baffles, the two ends of the plate body are provided with end baffles, the outer sides of the end baffles are provided with limiting blocks, the plate body is fixedly provided with a plurality of rubber modules by rivets, the rubber modules are uniformly distributed on the plate body, one ends of the end baffles are female die aluminum section bars, the other ends of the end baffles are male die aluminum section bars, and the side baffles are respectively convex aluminum section bars and concave aluminum section bars which correspond to the female die aluminum section bars and the male die aluminum section bars at the two ends of the end baffles. Through fixing the rubber modules on the plate body through the rivets, the size and the quantity of the modules can be conveniently set according to the needs, and the use is very convenient. The non-metal sound barrier die is simple in manufacturing process, long in service life and low in cost, and the size of the die can be flexibly adjusted according to the design.

Description

technical field [0001] The invention relates to the field of mechanical mold equipment, in particular to a non-metal sound barrier mold. Background technique [0002] Non-metallic sound barriers are mainly used in high-speed railways, rail transit, railways, urban viaducts, expressways, industrial noise reduction and other fields. Non-metallic sound barriers are divided into integral type and plug-in type. The main materials of the plug-in type are cement perforated board, perlite board, cement sawdust board, glass fiber reinforced cement board (GRC) and so on. The integral type has perlite board, cement sawdust board and so on. The integral non-metallic sound-absorbing panel is heavy, has good anti-collision performance, and has a long service life. The plug-in non-metal sound-absorbing panel is easy to manufacture and install, and the screen body is rich in color. At present, there is a great demand for sound barriers in the market, but the existing non-metallic sound ...

AI Technical Summary

Problems solved by technology

At present, the demand for sound barriers in the market is very large, but the existing non-metallic sound barrier molds have complicated production processes, and the design is not flexible enough. The size of the mold cannot be flexibly adjusted according to the thickness of the required sound-absorbing panels, and the cost is relatively high.
