Silencer cover sealing method

Abstract

The invention provides a silencer cover sealing method. The method includes the steps that through an upper drive system, a lower drive system and a cover sealing and wheel pressing method, the upper and lower ends of a silencer are synchronously subjected to cover sealing, the efficiency of silencer cover sealing is improved, a turning-around and clamping procedure of two-time silencer cover sealing is omitted, and the processing cost of the single silencer is reduced; a double-end drive pattern is adopted to avoid the risk that during one-end drive, due to the situation that a silencer cylinder is adopted to transmit torque, the silencer cylinder is stressed and deformed, and the yield of silencer cover sealing is increased; meanwhile, cover sealing pressing wheels adopt two-time cover sealing processes, firstly, an arc-shaped groove is adopted to make end covers bent and deformed, then, a vertical edge is adopted to make the end covers completely attached, the evenness and tightness of the end covers and cylinder cover sealing are improved, and the appearance quality of the whole silencer is improved.

Description

technical field [0001] The invention relates to the technical field of a capping machine, in particular to a method for capping a muffler. Background technique [0002] With the continuous improvement of people's living standards, automobiles are becoming more and more popular as a means of transportation. The power source of automobiles, the engine, will produce a large amount of exhaust gas during operation. Reduce exhaust gas pollution and reduce noise. The exhaust muffler of a car is the main component of driving noise. All countries in the world have strict regulations on the noise limit of various vehicles. The exhaust muffler is such a device for reducing exhaust noise. The function of the exhaust muffler is to reduce and attenuate the pulsation of the exhaust pressure. To eliminate noise, the absorption muffler reduces the energy of the exhaust gas by friction on sound-absorbing materials such as glass fiber, steel fiber and asbestos; the main function of the automo...

Problems solved by technology

[0003] In order to overcome the following problems in the prior art, the capping method is unilateral capping, and the other end is sealed after one end is sealed. The capping efficiency is relatively low, and the capping adopts a one-time capping method of pressing rollers. The joint part of the cylinder body and the cover body is uneven, the sealing effect is not good, and it is easy to leak air, thus affecting the overall quality of the muffler. The invention provides a muffler sealing method, through two sets of driving systems With the method of capping and pressing rollers, the upper and lower ends of the muffler are capped at the same time, which improves the capping efficiency of the muffler, reduces the turning and clamping process when the muffler is capped twice, and reduces the processing cost of a single muffler. The method avoids the risk of using the muffler cylinder to transmit torque when one end is driven, which leads to the risk of deformation of the muffler cylinder, which improves the yield of the muffler cap; at the same time, the capping process of two capping rollers is adopted, first bending deformation and then completely The way of bonding improves the uniformity and sealing of the end cover and the cylinder cover, and improves the overall appearance quality of the muffler
