Description

Silencer for water expansion machine

Technical Field

The utility model relates to a water rises the muffler field of machine, specifically is a muffler that is used for water to rise machine.

Background

The water expansion type hydraulic press is a machine which uses emulsified water as a liquid transmission medium and converts the mechanical energy of the hydraulic press into the kinetic energy of water to process products made of various materials such as stainless steel, aluminum, copper, iron and the like. The method is used for forming the internal high-pressure expansion type, such as extrusion, texturing, stamping and the like. The principle of the hydraulic transmission mechanism is that the hydraulic transmission mechanism is made by using the Pascal law and has a plurality of types. Of course, the use is also diverse as required. For example, the pressure-transmitting fluid may be classified into two types, i.e., an oil press and a water press.

The water expansion forming is also called as 'internal high pressure forming', and the basic principle of the water expansion forming is that a pipe is used as a blank, and ultrahigh pressure liquid is applied to the inside of the pipe, and simultaneously, axial thrust is applied to two ends of the pipe blank to supplement materials. Under the combined action of the two external forces, the tube blank material is subjected to plastic deformation and finally attached to the inner wall of the mold cavity, so that the hollow part with the shape and the precision meeting the technical requirements is obtained.

The water expansion machine usually generates larger noise during working, the noise mainly comes from the extrusion of blanks and the water expansion forming process, and the existing water expansion machine cannot meet the requirement of silencing in large-scale silencing factories, so that the silencer for the water expansion machine is required.
