Specific embodiment
- Fig. 2 referring to Fig.1, a kind of corrugated pipe forming machine of band flaring function of the invention.
A kind of corrugated pipe forming machine of band flaring function, including rack 1, mold, distribution box, fuel tank, water tank and for supplying
The water pump of water, the overall structure of fuselage are three beams, four rod structure, respectively by upper beam 33, central sill 32, underbeam 31, as the four of guide post
Root post and fastening nut are assembled, and wherein upper beam 33 and underbeam 31 are combined by four columns and 12 fastening nuts
It is installed in rack 1 at a fixed mechanism, the precision of machine is mounted on the nut in four columns to adjust.In 33 He of upper beam
The cylinder barrel of master cylinder 5 can be fixed on by setting one along the central sill 32 that guide post 2 moves up and down on guide post 2 among underbeam 31
On beam 33, the piston rod of master cylinder 5 is set to connect central sill 32, central sill 32 can move up and down under the action of master cylinder 5 along guide post 2.
Two 41 Hes of left side cylinder that can be moved in the horizontal direction are installed in the two sides relative position of four columns respectively on underbeam 31 again
Right side cylinder 42, is mounted on a plug on the piston rod of 42 inside of 41 inside of the left side cylinder and right side cylinder, and plug can be
It squeezes among horizontal direction under the action of two side cylinders or removes out outward, give pipe 64 1 axis when realizing high-pressure liquid-filling molding
To the function of reinforcing feed supplement.The plug is hollow structure simultaneously, is equipped with a water injection hole in the side of plug, is used for pipe
High pressure water is injected in 64.The present invention is suitable for the mold of diversified forms, and the mold includes assembled mould and chain type drawing-type
Mold；The mold for bellows processing is divided into matrix and lower matrix simultaneously, and upper matrix is mounted on the lower surface of central sill 32, under
Matrix is mounted on the upper surface of underbeam 31, for the ease of the installation and replacement of upper/lower die, also especially in central sill 32 and underbeam 31
On devise for mold installation mounting groove 7, increase mold installation when forced area guarantee mold stabilization, also be replacement
When disassembly increase convenience.One flaring cylinder 6 is set before high-pressure liquid-filling shaping station, is flared the rodless cavity and master cylinder 5 of cylinder 6
Epicoele pass through oil pipe connect.When 5 backhaul of master cylinder, the hydraulic oil of 5 epicoele of master cylinder will enter the rodless cavity of flaring cylinder 6, push away
The piston rod movement of dynamic flaring cylinder 6 is staggered to carry out this guarantees the high-pressure liquid-filling process of bellows and flaring process,
The process that ensure that flaring cylinder 6 does not interfere with the precision and efficiency of high-pressure liquid-filling molding procedure.On the piston rod of flaring cylinder 6
A flaring fixing seat is arranged in the first 61 motion bit front ends of flaring push top in one first flaring push top 61 of connection, and flaring is fixed
It is provided with more than two adjusting brackets 63 for being used to support pipe 64 on seat, and expands with the first flaring push top 61 matched second
Mouth push top 62.By being flared the setting of cylinder 6, remaining power consumption in reasonable utilization 5 quick return of master cylinder saves a machine
Bed.Flaring station is arranged before high-pressure liquid-filling shaping station simultaneously, realize an operative employee while operating two processes,
Human cost is greatly saved, is completed at the same time flaring process in the molding of bellows high-pressure liquid-filling, improves production efficiency.
For above-described embodiment, the master cylinder 5 is primary and secondary cylinder structure, and the cylinder barrel of mother's cylinder is connect with upper beam, the son
The piston rod of cylinder is connect with central sill.Primary and secondary cylinder is that typical quick cylinder structure is increased by using primary and secondary cylinder as master cylinder 5
Velocity mode when master cylinder 5 moves, the i.e. speed of crossbeam may be implemented 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 safety of molding at a slow speed, quickly
Backhaul is guaranteeing to divide the efficiency of mould simultaneously, and a powerful power can be provided to flaring cylinder 6 by returning guarantee.It is flared quality requirement
Higher, angle, surface quality and the tubing position length of flare formation have stringenter size requirement, are flared the quality of quality
Directly influence the quality of filling liquid molding procedure.And the very strong driving force for being flared cylinder 6 is exactly an important guarantee for being flared process, because
This passes through the quick return of primary and secondary cylinder, ensure that the quality of flaring process.
It further, further include the supercharging device filled the water for the pipe 64 into mold, the supercharging device includes pressurization
The piston rod of cylinder and water vat, the water vat is driven by the pressurized cylinder.The effect of water vat be in high-pressure liquid-filling molding procedure to
Pipe 64 provides high pressure water, guarantees that pipe 64 can be with high-pressure molding；Pressurized cylinder provides sufficiently large propulsive force then for water vat.Simultaneously
Also high speed water-filling function at the beginning may be implemented, improve the efficiency of bellows production.
The course of work of the invention is briefly described below:
First procedure of bellows production is flared to pipe 64, and second operation work is that the pipe 64 that will be flared is sent into
High-pressure liquid-filling molding is carried out in mold, ultimately forms bellows.
It is put into lower mold by the pipe being flared 64, the pipe 64 in the side cylinder of left and right two while downwards mold leans on
Closely, two plugs go deep into simultaneously and seal up the flaring at 64 both ends of pipe, while master cylinder 5 drives central sill 32 to drive upper matrix quick
It moves down, switchs to pattern at a slow speed when close to mold, until upper matrix and lower matrix tight structure.Further, water pump
Water in water tank is extracted into water vat, then pressurized cylinder applies a propulsive force to the piston rod of water vat, and 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, pressure of 64 wall of pipe by powerful high pressure water, and to expand, when due to expansion, pipe 64 can shorten,
So two side cylinders can promote in axial reinforcing simultaneously, guarantee the sealing effect of plug.Added by 64 internal pressurization of pipe with axial
The effect into supplementary material and mold cavity is pushed, required bellows form is ultimately formed.
After letting out load, 5 quick return of master cylinder, the hydraulic oil of 5 epicoele of master cylinder enters the rodless cavity of flaring cylinder 6, pushes and expands
The piston rod of mouth cylinder 6 carries out flaring process to the pipe 64 not being flared in flaring fixing seat.Since the backhaul of master cylinder 5 is in bellows
High-pressure liquid-filling molding procedure after carry out, so only needing an operative employee that can carry out the operations of two processes simultaneously.
The above, only presently preferred embodiments of the present invention, the invention is not limited to above embodiment, as long as
It reaches technical effect of the invention with identical means, all should belong to protection scope of the present invention.
