Puffing composite line for clutch facing and preparation method and processing equipment of puffing composite line

Abstract

The invention discloses a puffing composite line for a clutch facing and a preparation method and processing equipment of the puffing composite line for the clutch facing. Glass fiber filaments and chemical fiber filaments are subjected to puffing treatment through first turbulent flow gas and second turbulent flow gas respectively, the first turbulent flow gas is formed in a first puffing cavity under the action of first high-pressure gas, the second flow gas is formed in the second puffing cavity under the action of second high-pressure gas; prepolymerization is carried out on the glass fiber filaments, the chemical fiber filaments and the metal wires; and the glass fiber filaments, the chemical fiber filaments and the metal wires are jointly subjected to puffing composite treatment through third turbulent flow gas, and the third turbulent flow gas is formed in a third puffing cavity under the action of third high-pressure gas. According to the puffing composite line for the clutch facing and the preparation method and the processing equipment of the bulking composite line, the composite uniformity of the prepared bulking composite line can be high, meanwhile, the requirement for the pressure stability of output gas of a high-pressure gas supply system is lowered, and the preparation cost of the bulking composite line is remarkably reduced.

Description

technical field [0001] The invention generally relates to the technical field of friction materials, in particular to an expanded composite line for clutch face sheets, a preparation method and processing equipment thereof. Background technique [0002] As the core material for preparing the clutch face, the performance of the composite wire has a great influence on the quality of the clutch face. In particular, the puffed composite wire has better properties such as dipping, which can improve the performance of the clutch face. Please refer to the patent (the publication number is CN107190386A, the patent name is the preparation method of filament composite wire for automobile clutch face sheet), the filament composite wire for automobile clutch face sheet includes glass fiber filament, chemical fiber filament and metal wire, and the preparation of composite wire The process includes: passing glass fiber filaments and chemical fiber filaments through the puffing nozzle, inj...

AI Technical Summary

Problems solved by technology

[0003] The above process needs to ensure that the pressure stability of the high-pressure gas injected into the puffing nozzle is excellent, otherwise the composite winding uniformity of the puffed composite yarn prepared will be relatively poor, which will affect the balance of the performance of the clutch face

However, in order to meet the pressure stability requirements of high-pressure gas, it is usually necessary to configure a foreign gas supply system, which is not only expensive but also needs to train corresponding operating engineers, resulting in a higher cost of the puffing composite line
