Embodiment

[0017] Embodiment: heat insulation muffler production process, its process steps are as follows:

[0018] 1. Cutting the material to obtain the inner tube and outer tube that meet the requirements;

[0019] 2. The outer surface of the inner tube is wrapped with glass fiber or asbestos as insulation

[0020] This step can be implemented in two ways, namely "split-line" and "simplified":

[0021] 1) Split-line process: the diameter of each strand of asbestos (multi-strand wire) is 1mm, and each strand is composed of 12 strands, which are divided into single-strand ropes. Winding from the beginning to the end, so that the filling on the outer surface of the inner tube is uniform, and then put it into the outer tube, it can solve the problem of uneven filling or small gap;

[0022] 2) Simplified process: first cut off the finished empty tube filler according to the required size, then put the tube filler on the outer wall of the inner tube, and then put the inner tube with the f...

Abstract

The invention relates to a manufacturing technique of insulating silencer, which comprises the following processes: blanking-inner coating heated matters (fiber glass or asbestos)-putting into the outer tuber-composite welding-bending-tail tube composition-plating. The treatment methods of the inner coating hot matters have the distributing method, which divides the fiber glass or asbestos into thin lines to wind single-layered or multi-layered, or the compact method, which makes the fiber glass or asbestos into the barrel-shape corresponding to the inner tuber outline and directly sleeves it on the inner tube and covers the outer tuber after the insulating coating. The invention through the filling of the insulating matters between the inner and the outer tubes ensures the minimum clearance and the well proportion of the clearance.

Description

technical field [0001] The invention belongs to the technical field of vehicle mufflers, and in particular relates to a heat insulation muffler production process. Background technique [0002] The muffler is an indispensable and important part of motorcycles, and it plays a decisive role in environmental protection. Especially in the process of use, the muffler is affected by the engine, which often causes the outer tube of the muffler to become hot, and the chrome-plated surface becomes "yellow" and "blue", which seriously affects the use and appearance of the motorcycle. This is the motorcycle industry. A difficult problem that is currently almost insoluble. Aiming at this problem, the applicant, after a lot of practice and analysis, found that the occurrence of this problem mainly depends on the too small gap between the inner and outer tubes of the muffler. Therefore, how to control the gap between the inner and outer tubes becomes the key to solving the problem. [...
