Sound-absorbing cotton cutting device and cutting method adopting double tools

Abstract

The invention provides a sound-absorbing cotton cutting device adopting double tools. The sound-absorbing cotton cutting device is characterized by comprising the tools, a fixing plate, an upper plate surface and a pressing die; each tool is provided with a cutting edge, the end, far away from the cutting edge, of each tool is fixed to the fixing plate, the tools are arranged on the fixing plate in an enclosing manner in the shape into which the sound-absorbing cotton needs to be machined, the pressing die is fixed to the fixing plate along the inner sides of the tools, the upper end of the pressing die is lower than the upper ends of the tools, and the upper plate surface is made of high hardness steel with the hardness of about 55 and is capable of bearing punching force of about 100 t. In the cutting process, the upper plate surface bears the punching force, and the sound-absorbing cotton is extruded by the upper plate surface and the tools at the high pressure and cut off. The periphery of the cut sound-absorbing cotton die is extruded through the pressing die but not cut off, and edge sealing is achieved. By the adoption of the cutting device, the production efficiency can be improved, and the edge sealing effect can be improved.

Description

technical field [0001] The invention relates to a sound-absorbing cotton cutting device and a cutting method using double knives. Background technique [0002] The production and forming of sound-absorbing cotton is currently on the market mainly by laser cutting to achieve the desired shape. The advantage of laser cutting is that the sample production speed is fast and the technical difficulty is low. The disadvantage is that the efficiency is low during mass production, and the cut surface of the product cannot be cracked to achieve the edge banding effect, and the internal materials of the product will be scattered. Contents of the invention [0003] The main purpose of the present invention is to provide a sound-absorbing cotton cutting device and a cutting method using two knives, which are used to solve the above problems, so as to improve the cutting efficiency of the sound-absorbing cotton and improve the cutting effect. [0004] In order to achieve the above pur...
