Description
Technical field
The present invention relates to pipe fitting bending techniques field, more particularly to a kind of compound caliber thin-wall pipe pane bending apparatus.
Background technology
Pipe bending technique has widely in a variety of industries such as aerospace industry, shipping industry and automobile industry at present
Using the promotion of pipe bending technique has vital effect to the increased quality of these commercial products.
Existing general angle pipe equipment is roughly divided into three kinds：(1) general three-wheel bending roll machine, it is generally used for large and medium-sized sky
Really, the rolling that pass through sometimes repeatedly back and forth can be only achieved defined requirement to the ten thousand of heart pipe or solid bar, and piece surface is easy
It scratches or generates larger deformation on section, part consistency after molding is poor, and production efficiency is relatively low, therefore is only applicable to
The production of small lot, and used when product is drawn a design；(2) development of rotating disc type bending machine, the machine is very fast, existing programmable
Bending machine can the multiple and different directions of disposable clamping continuous bend and the identical part of bending radius, and the consistency of part it is good,
It is efficient, it is widely used.The cost of the higher price of single machine device, production is also done, and a secondary mold can only be bent
It is smaller for the accessory size being bent, bending essence to be commonly used in relative bending radius for the part of same bending radius
Spend higher part；(3) centering cart-wheel pipe bender, the function of such type and rotating disc type bending machine is essentially the same, and difference exists
It is only used for not core pulling in the machine and can be achieved with the part of bending, and can realize a part both ends while be bent, but it
It equally can not achieve the part that bending becomes radius.
But at present each bending radius of thin-wall pipe bending forming is required for matching due to the limitation of curved mould technology
A standby curved mould, and curved mould will be reinstalled for the curved section of the differently curved radius of pipe fitting could process, this causes
For there is the pipe fitting of the differently curved radius of multistage to need repeatedly processing that could complete so that thin-wall pipe bending forming process
Thin-wall pipe bending forming requirement that is time-consuming and laborious and cannot meeting complicated bend curve, which has limited thin-winding pipe technologies each
Application in each industry of row.

Specific implementation mode
Illustrate to elaborate for the present invention below in conjunction with the accompanying drawings：
As shown in Figures 1 to 3, the compound caliber thin-wall pipe pane bending apparatus of the present embodiment, including it is bend pipe guide rail 1, curved
Pipe sliding block 2, linear bearing 3, bend pipe pipe sleeve 4, right curved component 5, curved package traces 6, flexible pipe sleeve 7, left curved component 8 and pedestal 9.
Bend pipe pipe sleeve 4 is placed on bend pipe sliding block 2 with the formation of linear bearing 3 straight line pair and can be axial along bend pipe pipe sleeve 4
It is moved；The straight line pair that bend pipe sliding block 2 is formed with bend pipe guide rail 1 is fixed on pedestal 9；Left curved component 8 and right curved component 5 with
Curved package traces 6 form straight line pair and are fixed on pedestal 9；Flexible pipe sleeve 7 is fixed on pedestal 9.
Flexible pipe sleeve 7, multiple movable pipe sleeve sections 72 are connected by interior connecting plate 74 and outside link plate 71；Wherein movable pipe sleeve
Section 72 can be freely rotated around axis (hinge joint) to adapt to difference with interior connecting plate 74 and outside link plate 71 when pipe fitting feeds state
The pipe fitting of shape, and the 73 locking movable pipe sleeve section of electromagnetic clutch in pipe fitting bending forming state by being mounted on an axle
72, the relative rotation of interior connecting plate 74 and outside link plate 71 is to provide the uniform holding power needed for pipe fitting bending forming.
The square shaft of right curved component 5,52 lower section of curved mould is inserted into the square hole of curved mode slider 53；It is rectangular above curved mould 52
The square shaft of 53 top of axis and curved mode slider is inserted into the square hole of cover board 51；Need different curved moulds to be bent difference in pipe fitting
The quick-replaceable of curved mould 52 can be realized when curved diameter.
As shown in figure 4, the compound caliber thin-wall pipe pane bending apparatus of the present embodiment is curved to compound caliber thin-wall pipe
Bent forming process is as follows：
1) pipe fitting is to flexible pipe sleeve 7 from feeding along bend pipe pipe sleeve 4 is axial at bend pipe pipe sleeve 4, at this time the electromagnetism of flexible pipe sleeve 7
Clutch 73 is in releasing orientation, and movable pipe sleeve section 72, interior connecting plate 74 and outside link plate 71 can be freely rotated, flexible pipe sleeve
7 can change with the pipe shape of feeding to adapt to the shape of pipe fitting.Left curved component 8 and right curved component 5 along curved package traces 6 to
To concede the space of comer pieces feeding, the bending radius if necessary to change pipe fitting then replaces different curvature at this moment for both sides movement
Curved mould 52.
2) after feeding, 73 locking of electromagnetic clutch, movable pipe sleeve section 72, interior connecting plate 74 and outside link plate 71 can not
It relatively rotates.Simultaneously according to elbow curvature direction, the curved component 5 of left curved component 8 or the right side is close to pipe fitting by curved package traces 6 to be
Pipe fitting bending forming provides holding power.Back elbow sliding block 2 along bend pipe guide rail 1 move provide pipe fitting bending forming needed for act on
Power, in the process, linear bearing 3 and bend pipe pipe sleeve 4 can be opposite with bend pipe sliding block 2 with relative motion and linear bearing 3
Rotation enables comer pieces to be bent along curved mould bending direction.
In conclusion multiple segments that can be divided into pipe fitting of the present embodiment carry out bending forming, pipe fitting can be reduced in this way
The active force that pipe fitting is subject to when bending, during every segment pipe fitting is bent, bend pipe pipe sleeve 4 and flexible pipe sleeve 7 can be to pipes
Part provides uniform active force, improves the stressing conditions of comer pieces, can be realized by flexible pipe sleeve 7 and curved component thin to compound caliber
Wall pipe fitting continuous bend shapes.
