There is irreplaceable role in the fields such as line, lathe, household electrical appliances.
The manufacture of metal bellows at present mainly uses water swelling method：Pipe profile to be processed is placed in bellow forming
In tool, the then water filling into pipe profile, applying hydraulic pressure makes it expand outward, is processed into pipe profile under the extruding of molding die
Bellows.To overcome the hydraulic pressure of the intracavitary distending power caused by bellows forming die, need with clamping mechanism by bellows at
Pattern tool is locked.The main mode locking in such a way that hydraulic press pushes down mode locking or is clamped by spill fixture block of the prior art, lock
Mould power is all little, generally less than 200T, fine for producing micro metal bellows, but for producing larger complexity
It when metal bellows, is limited by its mode locking ability, generally using unicast molding machining, it is more can not disposably to process wave number
And heavy wall large size bellows, working efficiency is low, and final product quality is poor.

Pipe fitting to be processed is placed in lower die by mould, controls lifting cylinder retracted downward piston rod, drives upper mold to be closed with lower die, so
Control Mode-locking oil cylinder, by upper mold and lower die locked and fixed, then controls molding die two by mode locking pin push-in mode locking hole afterwards
The axial pressing oil cylinder of side, promotes to centre, is sealed pipe fitting both ends to be processed by sealing element, backward pipe fitting in water filling
Pressure so that pipe fitting forms primary ripple under the expansive force of inside water pressure and the extruding force collective effect of molding die, then
The ambilateral axial pressing oil cylinder of shaping mould continues to push against interior die blade so that pipe fitting forms final ripple, completes bellows
Processing, removes the hydraulic pressure of inside pipe fitting, and the axial pressing oil cylinder for controlling both sides exits, while controlling Mode-locking oil cylinder by mode locking pin
It recalls, upper mold is then lifted by lifting cylinder, take out the ripple tube workpiece machined.
The method have the benefit that：（1）, in such a way that Mode-locking oil cylinder pushes pin molding die locked,
Clamp force is big, when producing longer large-scale bellows, can increase Mode-locking oil cylinder while extending the length of molding die
Quantity improve clamp force, it is inadequate without having to worry about mold bearing capacity, can disposably complete complicated large-scale bellows and add
Work, work efficiency is high, quality of finished product good；（2）, two lifting guide pillars arranged side by side setting so that upper mold is rising or is declining
Shi Gengjia is steady, not will produce multidirectional displacement, and the chimeric between lower die is more tight；（3）, molding die use inside and outside
The structure of the form of mould, internal model die blade is designed according to the characteristic of bellows, by setting different inner diameters, different spacing
Matrix combines, you can and it is suitable for the bellows production of different size, different tube diameters, casts new molding die without specially opening,
Production efficiency is not only increased, while also greatly reducing production cost.
