Description
Technical field
The present invention relates to a kind of quick trimming device of metal bellows and the method for the quick trimming of metal bellows.
Background technology
Bellows is formed by connecting by circular thin-wall circle ripple one by one, according to customer requirement, bellows both ends
Need outwards to rout up two sides.Common processing method is after former and later two ripples are clipped with special fixture, on forcing press
First wave is flattened, the end face of left and right two of bellows is tightly fit together, then clamps ripple with another fixture again
Ripple external diameter after pipe is flattened both sides by method for turning on horizontal lathe is worked into design size.Because the wall of bellows
Thickness only has 0.15mm~0.5mm, flattens ripple external diameter and pass through turnery processing, originally two be close to the corrugated end face that is combined just oneself
So separation.Bellows trimming program：Installs fixture --- flattens --- fixture separation --- changing another fixture --- lathe car
It is cylindrical --- fixture is separated, and whole clamping process is all manually carried out, and one working day of a masterful technique worker can only
200 bellowss are processed, production efficiency is very low, and on the other hand, lathe process system lathe tool in metal surface marks cut channel and final
Trimming is realized, lathe tool can produce cutting chip when wavy metal pipe surface is slided, and cause cutting environment very poor, the chip of cutting
Fly out with the rotation of metal bellows, easily operator is damaged.
With the industrial development of modern domestic, bellows is as a flexible member.It has many characteristics, fortune
It is very wide with prospect.The vacuum switch tube of the industry such as national grid and mine electrical appliance needs bellows up to ten million in 1 year
Only.Vacuum heat collection pipe in country advocates in recent years solar light-heat power-generation and central heating industry, bellows need for 1 year
The amount of asking reaches millions of etc., and the speed of existing metal bellows trimming device machining bellows does not catch up with market much
Demand.
The content of the invention
It is an object of the present invention to provide a kind of quick trimming device of metal bellows, solves metal wave in the prior art
Line pipe trimming efficiency is low, the technological deficiency of trimming low precision and trimming environment difference.
To solve the above problems, the technical solution used in the present invention is：A kind of quick trimming device of metal bellows, bag

The snap ring of shape, the first described groove and the second groove can be spliced into the low groove of annular；Described upper mould includes upper mold body,
Cross section is provided with described upper mold body as circular upper groove, the bottom of described upper groove is provided with to match with low groove
The projection for merging and extending downwardly from.The application descends mould to move up and down relatively by upper mould, to the wavy metal being placed on lower mould
Pipe carries out punching press, and the side of metal bellows is cut off, and prior art is changed to the mode of punching press by the application by the way of car
The side of metal bellows is cut off, the used time is significantly reduced, and improves the service efficiency of the application, and the application combination punch press repeats to transport
Capable accuracy ensure that bellows excision side after front and rear ripple size uniformity, avoid human factor influence cutting essence
Degree, quality level greatly improve, and the application does not need coolant in use, are also flown out without the chip of cutting, improve gold
Belong to the environment and security of bellows trimming processing.
As a further improvement on the present invention, in addition to upper fixed seat, described upper mold body are arranged on upper fixed seat,
Described upper fixed seat is used to be detachably arranged in punch press, and the application uses upper fixed seat, the convenient upper mould by the application
On punch press.

Embodiment two：
The technical scheme of the present embodiment is a kind of quick method for cutting edge of metal bellows, using the wavy metal described in embodiment one
Quick trimming device is managed, the structure of the specific quick trimming device of metal bellows is shown in embodiment one, and it will not go into details for the present embodiment,
The method of the present embodiment specifically includes following seven steps：
Step 1, the application is arranged on punch press, using bolt or other fixtures etc. by the lower fixed seat of the application
1 is detachably arranged on the workbench of punch press, and the upper fixed seat 12 of the application is arranged on into punch press using connectors such as bolts
Knockout rod bottom, by the cylinder body of oil cylinder in the application be arranged on punch press lathe bed on.
Step 2, the piston retraction of oil cylinder, direction of the second lower die unit 3 of driving away from the first lower die unit 2 are manipulated
Motion, separates the first lower die unit 2 and the second lower die unit 3.
Step 3, metal bellows is placed in the first breach 4, the first snap ring 5 is stuck in metal bellows the top two
In the trough of individual ripple, for safe operation, place maloperation and cause mould to move downward suddenly and cause injury to personnel, this step
Suddenly using tweezers or other instruments gripping metal bellows, place it in the first breach 4.
Step 4, cylinder piston rod elongation is manipulated, the second lower die unit 3 of driving is moved towards the direction of the first lower die unit 2
To being fitted with the first lower die unit 2, now the second snap ring 8 is stuck in the trough of two ripples in metal bellows the top away from the
The side of one snap ring 5, metal bellows is stuck in snap ring, realizes the fixation of metal bellows.
Step 5, punch press work is driven, the knockout rod of punch press moves downward, and the upper mould of knockout rod driving of punch press moves downward,
The lower cutting edge of the upper cutting edge of upper mould and lower mould extrudes metal bellows when touching metal bellows at the same time, by the gold on lower mould
Belong to side and the straight tube excision on bellows top, the straight-tube portion of metal bellows extend into the upper of upper mold body 10 during being somebody's turn to do
In groove.
Step 6, repeat step 2, upper mould separate with lower mould, using instruments such as tweezers by metal bellows and removed
While being taken out from lower mould, and it is placed on after metal bellows is spun upside down in the first breach 4, repeat step 3-5, by metal wave
The side excision of the line pipe other end.
Step 7, repeat step 2, by removed both ends while metal bellows and cut away while take from the lower mould
Go out, complete the trimming of metal bellows.
The application will be changed to using punching press by the way of side of the lathe car except metal bellows both ends in the prior art
Mode is cut off, and improves the efficiency of metal bellows trimming, using the trimming device of the application, by the use of more days, and one
Common operative employee（To whether skilled operation lathe does not require）The ripple of 1000 or so can be processed a working day
Pipe, compared to the metal bellows of operative employee's processing 200 or so in one day of one skilled operation lathe of prior art, the application
Processing efficiency be greatly improved, and the application uses and with the accuracy that punch press reruns ensure that wavy metal
The uniformity of ripple size before and after pipe, the human factor for avoiding reception step cause the dimensional accuracy of the tip cut-off of metal bellows two
Inconsistent, quality level greatly improves.
It is prior art not do the part illustrated in description above, or can be realized by prior art.
And heretofore described specific implementation case is only the preferable case study on implementation of the present invention, not it is used for limiting the present invention's
Practical range.The equivalent changes and modifications that i.e. all contents according to patent of invention scope of the present invention are made, it all should be used as the present invention's
Technology category.
