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, whic

Embodiment 1

[0027] Based on the embodiment in the present invention, a kind of capping method of muffler, specifically as follows:

[0028] 1): Install and fix the positioning molds of the upper and lower workbenches. The shape and size of the positioning molds need to be compatible with the shape and size of the muffler end cap to be sealed. The muffler end cap to be sealed is circular with a diameter of ￠100mm;

[0029] 2): Use electronic weighing equipment to weigh the cylinder of the muffler. The set value of the weight of the muffler cylinder is 1.5Kg, and the error range is ±15g. The actual measured value is 1.510kg, which does not exceed the error range of the set value. Enough sound-absorbing glass fibers can achieve the set sound-absorbing function;

[0030] 3): Put the end cover of the muffler on the positioning mold of the lower workbench, with the joint surface of the end cover and the cylinder facing upwards, and then place the muffler cylinder with a length of 200mm vertical...

Embodiment 2

[0037] Based on the embodiment in the present invention, a kind of capping method of muffler, specifically as follows:

[0038] 1): Install and fix the positioning molds of the upper and lower workbenches. The shape and size of the positioning molds need to be compatible with the shape and size of the muffler end cap to be sealed. The muffler end cap to be sealed is oval, and the long axis of the end cap is 300mm, and the minor axis is 200mm;

[0039]2): Use electronic weighing equipment to weigh the cylinder of the muffler. The set value of the muffler cylinder is 6Kg, the error range is ±15g, and the actual measurement value is 5.995. It does not exceed the error range of the set value. Fill enough Noise reduction glass fiber can achieve the set noise reduction function;

[0040] 3): Place the end cover of the muffler on the positioning mold of the lower workbench, with the joint surface of the end cover and the cylinder facing upwards, then place the muffler cylinder with ...

Embodiment 3

[0047] Based on the embodiment in the present invention, a kind of capping method of muffler, specifically as follows:

[0048] 1): Install and fix the positioning molds of the upper and lower worktables. The shape and size of the positioning molds need to be compatible with the shape and size of the muffler end cover to be sealed. The muffler end cover to be sealed is circular with a diameter of ￠400mm;

[0049] 2): Use electronic weighing equipment to weigh the cylinder of the muffler. The set value of the weight of the muffler cylinder is 9Kg, the error range is ±15g, and the actual measured value is 9.010kg. It does not exceed the error range of the set value and is filled enough The sound-absorbing glass fiber can achieve the set sound-absorbing function;

[0050] 3): Place the end cover of the muffler on the positioning mold of the lower workbench, with the joint surface of the end cover and the cylinder facing upwards, then place the muffler cylinder with a length of 90...

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...
