Description
Technical field
The invention belongs to corrugated pipe forming technical fields, and in particular to a kind of bellows device for automatically molding.
Background technique
The hydraulic processing of metal bellows tubing be section be the annular corrugated pipes such as circle, ellipse, rectangle, track type at
The common process method of type.After the relative position for adjusting mold and blank, to the pressurising of blank inner cavity, then along its axial direction
Mechanical compression is carried out, a bellows to length just quickly forms.This is a kind of method of hydro-forming, is called more waves one
The secondary method of forming.The bellows for generally making elastic element, mostly uses this processing method.But to the ripple as metal hose ontology
For pipe, this method is just dying.Because this kind of bellows requires, the longer the better.For this purpose, people create it is another it is hydraulic at
The continuously shaped method of the method for type, i.e. unicast.It can in the case where blank length conditions permit, continuously shaped tens, several
Hundred or even thousands of, tens of thousands of a ripples.In use, can be intercepted by required length or required ripple number.In this sense,
It can replace more wave one-pass molding lathes.As long as replacing the mold of different size, so that it may produce the bellows of different size.
It can be said that the continuously shaped lathe of unicast is the multifunctional equipment of bellows processing, it is the key equipment on the production line.
Metal bellows unicast continuous forming machine in the prior art is revolved again after the waveform for squeezing one breakpoint of expansion
Jiggered piece certain angle squeezes the swollen processing for completing complete waveform again, thus needs to turn round matrix and load cylinder
Movement, mechanism is complex, and such structure causes diaphragm stability poor.
Summary of the invention
The object of the invention is that providing one kind to solve the above-mentioned problems and not needing matrix rotation, mechanism is more simple
It is single, driving mechanism needed for reducing rotary motion, and the more stable bellows of the mechanisms such as load cylinder fixed structure automatically at
Type device.
The present invention through the following technical solutions to achieve the above objectives:
A kind of bellows device for automatically molding, including the bulging device for forming ripple, which includes matrix
Shaping mechanism and and set on matrix shaping mechanism center taper load pressure head, matrix shaping mechanism include from top to bottom be laminated
The pressing plate of setting, upper bulging template, clamping plate, lower bulging template and backing plate, upper bulging template and lower bulging template are by multiple
The matrix unit composition of the fan ring of annular array distribution, the inner end of matrix unit are equipped with sliding block, and taper loads on the outer wall of pressure head
Equipped with axially disposed sliding slot, sliding block is in the sliding slot.
As a further optimization solution of the present invention, the matrix element number phase of the upper bulging template and lower bulging template
Together, be N, the matrix unit of upper bulging template and the matrix unit of lower bulging template are interspersed, staggered angle be 180 °/
N。
As a further optimization solution of the present invention, the spacing of the upper bulging template and lower bulging template is a unicast exhibition
Open length.
As a further optimization solution of the present invention, the bottom circular diameter of the matrix unit of the upper bulging template is swollen under being greater than
The bottom circular diameter of the matrix unit of shape template, this makes it possible to keep taper load pressure head to make the outer of two bulging templates afterwards in place
Circle is isometrical.
As a further optimization solution of the present invention, the cross section of the sliding block is T-shaped, the gradient and cone of the inner face of sliding block
The taper that shape loads pressure head is identical.
As a further optimization solution of the present invention, the fixing bolt through pressing plate, upper bulging template, clamping plate, under it is swollen

Reason is: motor drives elevating screw to rotate by chain conveyer, and four elevating screws are realized by chain drive and rotated synchronously, lifting
Rise while screw rod rotates since the effect of screw thread is synchronous, and then lifting platform is driven to rise overally；It is necessary, elevating screw
Top and lifting platform are rotatablely connected.
The corrugated pipe forming method of bellows device for automatically molding, includes the following steps:
Pipe is placed on lifting platform by step 1, by clamp pipe, while pipe and taper being made to load pressure head
Coaxially, lifting of lifting table is then driven by elevating mechanism, keeps lower bulging template consistent with the height of the swollen wave of starting of pipe, adds
Carrying oil cylinder drives taper to load pressure head downlink, pushes the matrix unit of lower bulging template to move out, carries out to external pipe
Bulging, generates intermittent waveform, and load cylinder drives taper load pressure head to reset, descends the diaphragm block of bulging template at the same time
Since the effect of sliding block and sliding slot resets；
Step 2 drives lifting platform to rise by elevating mechanism, so that pipe is axially moveable a unicast expansion length, at this time
Lower bulging template is consistent with pipe waveform height to be processed, and the intermittent waveform of upper bulging template and lower bulging die sheet metal forming is high
Degree is consistent；Load cylinder drives taper to load pressure head downlink, pushes the matrix unit of lower bulging template and upper bulging template outside
The pipe of movement, the lower external portion of bulging template carries out bulging, generates an intermittent waveform again, the upper external portion of bulging template
Pipe carries out bulging, and that eliminates the intermittent waveform of a upper generation does not squeeze one complete waveform of swollen raised stroke in place；
Then load cylinder drives taper load pressure head to reset, and descends the diaphragm block of bulging template due to sliding block and sliding slot at the same time
Effect resets；
Step 3 drives lifting platform to rise by elevating mechanism, and pipe is made to be axially moveable a unicast expansion length, according to
Step 2 makes up intermittent waveform and squeezes swollen next waveform, until processing target waveform number.
The beneficial effects of the present invention are:
1) present invention mutually makes up waveform breakpoint by the designs of two bulging templates, does not need matrix rotation, mechanism compared with
Be it is simple, reduce and driving mechanism and do not need to increase other driving mechanisms needed for rotary motion；
2) mechanisms such as load cylinder of the invention fixed structure is more stable；
3) for the present invention due to eliminating rotary motion, time and the original only processing for processing a complete waveform now are primary
It is identical to squeeze the swollen time, greatly improves work efficiency.
