Abstract
The present invention features that the silencing pipe and the partition board are first assembled and positioned in a pressure machine with special assembling fixture and the contact part between the silencing pipe and the partition board rise crest processed to lock the partition board in fixed position of the silencing pipe. The present invention can raise the vibration strength and heat deformation stability of silencer and prolong the service life of silencer.
Description
This invention relates to the assembling processing technique of a kind of automotive muffler hush tube and dividing plate.
Along with the continuous development shape of automobile industry is big.The exhaust silencer system production technology is updated, though the technology of silencing apparatus assembling has nothing in common with each other, but generally all adopt the way of welding, the welding way comprises spot welding and seam weldering, more than the shortcoming of two kinds of welding methods be: destroyed the corrosion protection coating of hush tube and baffle surface, the aging of hush tube and dividing plate accelerated in the moisture generation corrosion in the contact engine exhaust, when silencing apparatus is inner when big difference variation takes place easy sealing-off, directly influence the working life of silencing apparatus.
The purpose of this invention provides the assembling processing technique of a kind of automotive muffler hush tube and dividing plate, can fundamentally solve the corrosion protection oil reservoir of hush tube and baffle surface and the problem of easy sealing-off effectively, increases the service life.
Its technological scheme is: the hush tube of silencing apparatus and dividing plate are joined at the enterprising luggage of press machine by special tooling, finish Primary Location, on hush tube, carry out oncus processing by the oncus frock then, allow dividing plate just in time between the oncus of locking hush tube, realize fixedlying positioning with the dividing plate contacting point.The oncus frock of hush tube being carried out oncus processing is made of forming die, fixed plate, yoke plate etc., and the oncus frock provides power by hydraulic braking sytem.
On the noise elimination tube wall, carry out in the oncus course of working, can once on frock, finish the oncus location, many places of hush tube and dividing plate with the dividing plate contact segment.
In the oncus course of working, need the position of oncus for accurately detecting hush tube and dividing plate many places, in the relevant position of the oncus forming die of oncus frock the contact-type inductor is installed, the position information of judging in time can be fed back to hydraulic braking sytem and handle.
In the assembling course of working of automotive muffler hush tube and dividing plate, the technology that adopts this invention to provide can not destroyed the protective coating on dividing plate and hush tube surface, also improved tensile strength, thermomechanical stability is good, good airproof performance, production operation is easy, efficient height, the life-span of prolongation silencing apparatus.
Fig. 1 is the schematic representation that silencing apparatus hush tube and dividing plate carry out the oncus processing and assembling.
Further specify this invention below in conjunction with example, at first the oncus machine is made up of the Hydraulic braking system oncus frock of unifying, hydraulic braking sytem comprises hydraulic station, oil cylinder, structures such as contact-type inductor and equipment programmable controller, oncus frock part is by forming die, fixed plate, structures such as yoke plate play a role, forming die is cubic cone slip bulging structure, have cubic cone rise the axle and four blocks of plates that rise, rising has the oncus muscle on the position of plate respective fixation dividing plate, two muscle about each dividing plate and hush tube joint have, and four blocks of plates that rise draw in by " O " type rubber ring, under the effect of oil hydraulic cylinder, finish the muscle that rises, to reach the purpose of oncus.This method can once be finished on frock, and wherein the effect of yoke plate is once to drive single shaft or multiaxis work.
The operating process of assembling processing at first is that the hush tube and the dividing plate of silencing apparatus are joined at the enterprising luggage of press machine by special tooling, finishes Primary Location, moves on to then on the oncus machine worktable, sends the oncus forming die to hush tube under rounding state.Adapting under the effect of the contact-type inductor that the position installs with forming die, the position information of the oncus that accurately detects is fed back to hydraulic braking sytem to be handled, carry out oncus processing, under the drive of oil hydraulic cylinder, finish the muscle that rises, allow dividing plate just in time be locked between the oncus of hush tube, realization fixedly positioning, and gathering forming die under the effect of " O " type rubber ring allows constructional devices such as forming die withdraw from from hush tube at last.
Claims (4)
1, the assembling processing technique of a kind of automotive muffler hush tube and dividing plate, it is characterized in that hush tube and dividing plate join at the enterprising luggage of press machine by special tooling, finish Primary Location, on hush tube, carry out oncus processing by the oncus frock then with the dividing plate contact segment, allow dividing plate just in time be locked between the oncus of hush tube, realize fixedlying positioning.
2, the assembling processing technique of a kind of automotive muffler hush tube according to claim 1 and dividing plate.The oncus frock that it is characterized in that hush tube is carried out oncus processing is by forming die, fixed plate, formations such as yoke plate, and the oncus frock provides power by hydraulic braking sytem.
3, according to the assembling processing technique of claim 1 and 2 described a kind of automotive muffler hush tubes and dividing plate, it is characterized in that on the noise elimination tube wall, carrying out in the oncus course of working, can once on frock, finish the oncus location, many places of hush tube and dividing plate with the dividing plate contacting point.
4, according to the assembling processing technique of claim 1 and 2 described silencing apparatuss and dividing plate, it is characterized in that carrying out in the oncus course of working at noise elimination tube wall and dividing plate contact segment, need the position of oncus for accurately detecting hush tube and dividing plate many places, on the oncus forming die relevant position of oncus frock, the contact-type inductor is installed, the position information of judging in time can be fed back to hydraulic braking sytem and handle.
