Embodiment
Reference picture 1- Fig. 2, a kind of corrugated pipe forming machine with enlarging function of the invention.
A kind of corrugated pipe forming machine with enlarging function, including frame 1, mould, distribution box, fuel tank, water tank and for supplying
The water pump of water, the overall structure of fuselage is the rod structure of three beam four, respectively by upper beam 33, central sill 32, underbeam 31, four as guide pillar
Root post and clamp nut are assembled, and wherein upper beam 33 and underbeam 31 are combined by four root posts and 12 clamp nuts
It is installed on into a fixed mechanism in frame 1, the precision of machine is mounted on the nut on four root posts to adjust.In the He of upper beam 33
One central sill 32 that can be moved up and down along guide pillar 2 is set on the guide pillar 2 among underbeam 31, the cylinder barrel of master cylinder 5 is fixed on
On beam 33, the piston rod of master cylinder 5 is set to connect central sill 32, the can of central sill 32 moves up and down in the presence of master cylinder 5 along guide pillar 2.
The both sides relative position of four root posts installs two Hes of the left side that can be moved in the horizontal direction cylinder 41 respectively on underbeam 31 again
It is mounted on a plug on the piston rod of right side cylinder 42, the inner side of the left side cylinder 41 and the inner side of right side cylinder 42, plug can be
Level is extruded to centre or removed out laterally in the presence of two side cylinders, gives pipe 64 1 axles when realizing high-pressure liquid-filling shaping
To the function of reinforcing feed supplement.The plug is hollow-core construction simultaneously, and a water injection hole is provided with the side of plug, for pipe
Water under high pressure is injected in 64.The present invention is applied to the mould of diversified forms, and the mould includes assembled mould and chain type drawing-type
Mould；The mould for bellows processing is divided into matrix and lower matrix simultaneously, and upper matrix is arranged on the lower surface of central sill 32, under
Matrix is arranged on the upper surface of underbeam 31, for the ease of the installation and replacing of upper/lower die, also especially in central sill 32 and underbeam 31
On devise mounting groove 7 for mould installion, lifting surface area when increasing mould installion ensures the stabilization of mould, is also to replace
When dismounting add facility.One enlarging cylinder 6, rodless cavity and the master cylinder 5 of enlarging cylinder 6 are set before high-pressure liquid-filling shaping station
Epicoele connected by oil pipe.When 5 backhaul of master cylinder, the hydraulic oil of the epicoele of master cylinder 5 will enter the rodless cavity of enlarging cylinder 6, push away
The piston rod movement of dynamic enlarging cylinder 6, staggers this guarantees the high-pressure liquid-filling process of bellows and enlarging process to carry out,
It ensure that the process of enlarging cylinder 6 does not interfere with the precision and efficiency of high-pressure liquid-filling molding procedure.On the piston rod of enlarging cylinder 6
One the first enlarging of connection cuts somebody's hair 61, sets an enlarging fixed seat in the first enlarging 61 motion bit front ends of cutting somebody's hair, enlarging is fixed
Two or more is provided with seat and is used to supporting the adjusting bracket 63 of pipe 64, and cuts somebody's hair and the second of 61 matchings expands with the first enlarging
Mouth cuts somebody's hair 62.By the setting of enlarging cylinder 6, remaining power consumption in the quick return of master cylinder 5 is reasonably make use of, saves a machine
Bed.Before enlarging station is arranged on into high-pressure liquid-filling shaping station simultaneously, realizes an operative employee while operate two processes,
Human cost is greatlyd save, is molded in bellows high-pressure liquid-filling and completes enlarging process simultaneously, improve production efficiency.
For above-described embodiment, the master cylinder 5 is primary and secondary cylinder structure, and the cylinder barrel of female cylinder is connected with upper beam, the son
The piston rod of cylinder is connected with central sill.Primary and secondary cylinder is typical quick cylinder structure, by using primary and secondary cylinder as master cylinder 5, is added
Velocity mode when master cylinder 5 moves, the i.e. speed of crossbeam can realize following Three models：Fast downlink, at a slow speed pattern and fast
Fast backhaul.Fast downlink improves the operational efficiency of bellows machine, and pattern ensure that the precision and security of matched moulds at a slow speed, quickly
Backhaul is ensureing to divide the efficiency of mould simultaneously, and a powerful power can be provided to enlarging cylinder 6 by returning guarantee.Enlarging quality requirement
Higher, angle, surface quality and the tubing position length of flare formation have stricter size requirement, the quality of enlarging quality
Directly influence the quality of topping up molding procedure.And the very strong driving force of enlarging cylinder 6 is exactly an important guarantee of enlarging process, because
This ensure that the quality of enlarging process by the quick return of primary and secondary cylinder.
Further, in addition to the supercharging device for the water filling of pipe 64 into mould, the supercharging device include supercharging
Cylinder and water vat, the piston rod of the water vat are driven by the pressurized cylinder.The effect of water vat be in high-pressure liquid-filling molding procedure to
Pipe 64 provides water under high pressure, ensures that pipe 64 can be with high-pressure molding；Pressurized cylinder then provides sufficiently large propulsive force for water vat.Simultaneously
High speed water-filling function at the beginning can also be realized, improves the efficiency of bellows production.
The course of work of the present invention is briefly described below：
First procedure of bellows production is to give the enlarging of pipe 64, and second operation work is to be sent into the good pipe 64 of enlarging
High-pressure liquid-filling shaping is carried out in mould, ultimately forms bellows.
It is put into by the good pipe 64 of enlarging in lower mould, the pipe 64 in the side cylinder of left and right two while downwards mould leans on
Closely, two plugs deeply and seal up the enlarging at the both ends of pipe 64 simultaneously, while master cylinder 5 drives central sill 32 to drive upper matrix quick
Move down, switch to pattern at a slow speed when close to mould, until upper matrix and lower matrix tight structure.Further, water pump
Water in water tank is extracted into water vat, then piston rod application one propulsive force of the pressurized cylinder to water vat, the water in water vat is fast
Speed is injected in pipe 64 from the cavity of plug by water injection hole.After the water in pipe 64 fills, in pressurized cylinder and water vat
Continue under effect, the wall of pipe 64 by powerful water under high pressure pressure, and to for expansion, due to expansion when pipe 64 can shorten,
So two side cylinders can axially be reinforced and promoted simultaneously, ensure the sealing effectiveness of plug.Added by the internal pressurization of pipe 64 and axial direction
The effect into supplementary material, and mold cavity is pushed, ultimately forms required bellows form.
After load is let out, the quick return of master cylinder 5, the hydraulic oil of the epicoele of master cylinder 5 enters the rodless cavity of enlarging cylinder 6, promotes and expands
The piston rod of mouth cylinder 6 carries out enlarging process to the pipe 64 of non-enlarging in enlarging fixed seat.Because the backhaul of master cylinder 5 is in bellows
High-pressure liquid-filling molding procedure after carry out, so only need operative employee's can and meanwhile carry out two processes operation.
It is described above, simply presently preferred embodiments of the present invention, the invention is not limited in above-mentioned embodiment, as long as
It reaches the technique effect of the present invention with identical means, should all belong to protection scope of the present invention.
