Detailed Description
The invention is further illustrated by the following examples in conjunction with the accompanying drawings:
referring to fig. 1 to 5, a method for manufacturing a muffler sound-absorbing cotton metal mesh framework includes the following steps:
(1) because the models and sizes of the inner frameworks 1 of the sound-absorbing cotton metal net frameworks of the silencers of different models are different, the metal mesh belt 3 with proper width and shape is required to be calculated according to the models and sizes of the inner frameworks 1 of the sound-absorbing cotton metal net frameworks of the silencers, the width of the metal mesh belt 3 is also provided with a sewing allowance 5 for sewing, and the metal mesh belt 3 can be directly connected to the outside of the inner framework 1 of the sound-absorbing cotton metal net framework of the silencers after being sewn by the arrangement of the sewing allowance 5;
(2) superposing two sides of a metal mesh belt 3, wherein the superposed width is the width of the sewing allowance 5, and sewing the metal mesh belt 3 in the sewing allowance 5 area through a sewing line on a sewing machine;
(3) the sewed metal mesh cylinder 2 is sleeved outside the inner framework 1 of the sound-absorbing cotton metal mesh framework of the silencer, and the inner framework 1 of the sound-absorbing cotton metal mesh framework of the silencer is subjected to outer shell injection molding through an injection molding machine. After 2 cover of a metal mesh section of thick bamboo establish the muffler and inhale the inner frame 1 of sound cotton metal mesh skeleton, carry out the moulding plastics of shell body with filter screen inner frame 1 for a metal mesh section of thick bamboo 2 is fixed between filter screen inner frame 1 and shell body.
Further, the metal mesh belt is a stainless steel mesh grid. Specifically, the metal mesh adopts the stainless steel woven mesh which is high in strength, and the diameter of each silk thread is extremely small, so that the metal mesh can be quickly penetrated through the silk thread during sewing.
Furthermore, the suture line is made of environment-friendly cotton threads. Particularly, the suture line provided by the invention adopts environment-friendly cotton threads, and the environment-friendly cotton threads are low in price and more environment-friendly.
Further, the width of the sewing allowance 5 is 3-5 mm. Specifically, the width of the sewing allowance 5 is 3-5mm, the width is reasonable in design, and the sewing machine can quickly run the thread during sewing.
Further, a mark is fixed on the inner framework 1 of the sound-absorbing cotton metal mesh framework of the silencer, and the sewing allowance 5 area coincides with the mark area, so that after the outer shell is subjected to injection molding, the sewing allowance 5 is covered by the vertical ribs of the outer shell. The sewing allowance 5 is covered by the vertical ribs of the outer shell, the sewing allowance 5 is prevented from being exposed outside, and the functions of hiding the sewing allowance 5 and protecting the sewing allowance are achieved.
Further, when facing the inner frame of the sound-absorbing cotton metal mesh framework of the cylindrical silencer, as shown in fig. 3 to 4, a metal mesh belt 3 may be adopted, the length of the metal mesh belt 3 is several times of the length of the metal mesh cylinder 2 of the sound-absorbing cotton metal mesh framework of a single silencer, after sewing, cutting is performed according to the required length of the metal mesh cylinder 2 of the sound-absorbing cotton metal mesh framework of the silencer, and the notch 4 is as shown in fig. 4; traditional welding mode is replaced through this kind of mode of making up, at first can make metal mesh belt 3 can stitch through sewing machine is quick, 1 m's metal mesh only needs 30 seconds the time can sew up the completion, and 1 m's metal mesh can be cut apart into a plurality of metal mesh section of thick bamboo 2 again, production efficiency obtains improvement by a wide margin, in addition, owing to adopt sutural mode preparation metal mesh, the metal mesh damage that can avoid the welded mode to cause burns out, almost there is not the production of waste product, very big reduction manufacturing cost.
The foregoing detailed description of the preferred embodiments of the invention has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts.
