Abstract
The utility model provides a core silencer of a stainless steel fibre device for the technical field of an automobile silencer. The utility model is characterized in that stainless steel fibre shag is wound into a cylinder shape, and the cylinder can form a rectangle shape, a trapezoid shape and a circle shape and is used for matting at the inner layer of a rock wool of the silencer. The used stainless steel fibre uses 1Cr17Mo materials, a screw framework is arranged at the inner layer of a fiber shag cylinder, the screw framework is wound into the cylinder shape by residue materials, the requirement of the thickness is b = 0.70-0.85MM, and the framework rotates in the left direction. Compared with the existing silencer technology, the utility model has the advantages of high temperature resistance, oxidation resistance and corrosion resistance, effectively suctions sound, lowers noise, protects rock wool, etc.
Description
The utility model belongs to the automotive muffler technical field, is a kind of Stainless Steel Fibre device core silencing apparatus.
Automotive muffler requires its internal structure to have measured to the greatest extent sqouynd absorption lowering noise function, and at present, silencing apparatus is to adopt to wrap the method for establishing rock wool in the device shell, but rock wool is under the long-time condition of high temperature, the surface is easy to oxidation and sinter, causes the silencing apparatus damage, and acoustic absorptivity reduces.Consider to adopt the steel fiber liner in the rock wool internal layer, the one, the protection rock wool, the 2nd, strengthen sound absorption.What at first consider employing is the carbon steel fiber, because the carbon steel fiber has its high-specific surface area that forms naturally, obvious to the sqouynd absorption lowering noise effect, but there are two fatal shortcomings in the carbon steel fiber, the one, oxidation at high temperature appears in non-refractory easily, and the sharp-pointed end face of its profiled-cross-section takes place by molten touching, specific surface area reduces, the 2nd, the poor ductility of carbon steel fiber, tensile strength is low, very easily occurs disconnected suede in working angles, cause carbon steel fibrous finished product rate low, coiling device core difficulty.
Based on the problems referred to above and analysis, it is the silencing apparatus of device core with the Stainless Steel Fibre that the purpose of this utility model provides a kind of, thereby resistance to high temperature oxidation is corrosion-resistant, has the good sound absorption anti-acoustic capability.
Technical solution adopted in the utility model is improved on the basis of existing silencing apparatus, set up stainless steel fibrous floss tube at silencing apparatus rock wool internal layer, fiber suede tube internal layer is provided with the spiral skeleton, and the spiral skeleton is tubular, thickness requirement b=0.70-0.85mm, skeleton Hand of spiral is left-handed.
Because the utility model has been taked technique scheme, compares with existing silencing apparatus technology, has resistance to high temperature oxidation, and is corrosion-resistant, effectively sqouynd absorption lowering noise, advantages such as protection rock wool.
Below in conjunction with accompanying drawing and example specific structural features of the present utility model is described further.
Fig. 1 represents acoustic wave filter structure schematic representation of the present utility model.
Fig. 2 represents muffler element structural representation of the present utility model
Muffler element has skeleton 2 as shown in Figure 2, the external packets of skeleton 2 establish Stainless Steel Fibre layer 1 as shown in Figure 1 silencing apparatus have housing 3, the middle part of housing 3 is provided with the outlet pipe 4 of band mesh, and the external packets of outlet pipe 4 is established device core 5, is rock wool layer 6 between device core 5 and the housing 3.Wherein, Stainless Steel Fibre layer 1 turns to tubular, and this tubular can be rectangle, trapezoidal, circular cylinder, is used for liner at silencing apparatus rock wool internal layer.Used Stainless Steel Fibre adopts the 1Cr17Mo material, and fiber suede tube internal layer is provided with the spiral skeleton, and the spiral skeleton adopts the Stainless Steel Wire clout to turn to tubular, thickness requirement b=0.70-0.85mm, and skeleton Hand of spiral is left-handed.
