Description
Technical field
The utility model is related to a kind of quick trimming devices 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
It needs 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 made tightly to fit together, then clamps ripple with another kind fixture again
Ripple outer 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 outer diameter by turnery processing, and originally two are close to the corrugated end face being combined just certainly
So separation.Bellows trimming program：Installs fixture --- flattens --- fixture separation --- changing another fixture --- lathe car
Outer circle --- fixture separates, and entire clamping process all manually carries 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
Realize trimming, lathe tool can generate cutting chip when wavy metal pipe surface is slided, and cause cutting environment very poor, the chip of cutting
It flies 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 industries such as national grid and mine electrical appliance needs bellows up to ten million in 1 year
Only.Evacuated collector tube 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.

Movement, separates the first lower die unit 2 and the second lower die unit 3.
Step 3, metal bellows is placed in the first notch 4, the first snap ring 5 is made to be stuck in metal bellows the top two
In the trough of a ripple, for safe operation, place maloperation and upper mold is caused to move downward suddenly and causes injury to personnel, this step
Suddenly using tweezers or other instruments gripping metal bellows, place it in the first notch 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 fitting with the first lower die unit 2, the second snap ring 8 is stuck in the trough of two ripples in metal bellows the top away from the at this time
The one side of one snap ring 5, metal bellows is stuck in snap ring, realizes the fixation of metal bellows.
Step 5, punching machine work is driven, the knockout rod of punching machine moves downward, and the knockout rod driving upper mold of punching machine moves downward,
The upper cutting edge of upper mold and the lower cutting edge of lower die squeeze metal bellows when touching metal bellows at the same time, by the gold in lower die
Belong to the side on bellows top and straight tube excision, 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, step 2 is repeated, upper mold separates with lower die, using instruments such as tweezers by metal bellows and removed
It while being taken out from lower die, and is placed on after metal bellows is spun upside down in the first notch 4, step 3-5 is repeated, 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 lower die
Go out, complete the trimming of metal bellows.
The application will be changed to by the way of side of the lathe car except metal bellows both ends using punching press 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
The metal bellows of pipe, the compared with the prior art operative employee of skilled operation lathe processing 200 or so in one day, the application
Processing efficiency be greatly improved, and the application uses and with the accuracy that punching machine 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 two tip cut-off of metal bellows
Inconsistent, quality level greatly improves.
The part illustrated is not done in description above to be the prior art or can realize by the prior art.
And the preferable case study on implementation that case is only the utility model is embodied described in the utility model, not it is used for limiting
The scope of the utility model.The equivalence changes that i.e. all contents according to the utility model utility model patent scope are made are with repairing
Decorations, all should be used as the technology scope of the utility model.
