Description
Technical field
The utility model is related to aluminium alloy SSAW pipe unit, more particularly to aluminium alloy spiral welded pipe spiral forming device to change
Enter.
Background technology
Aluminium alloy spiral welded pipe is the significant components of extra-high voltage electric transmission and transformation, existing aluminium alloy spiral welded pipe spiral forming dress
Put and constituted including a row inner circle pressure roller and at least six cylindrical pressure rollers of row, the cylindrical pressure roller is distributed uniformly and circumferentially, described
Inner circle pressure roller and cylindrical pressure roller are separately mounted to each on adjustable support, and described inner circle pressure roller and cylindrical pressure roller are at least by 6
Individual roller is fixedly mounted on wheel seat and constitutes side by side, and each roller is made up of support, support shaft, ball bearing, and ball bearing is solid
In support shaft, support shaft is fixedly mounted on support, and support is fixedly mounted on wheel seat for Dingan County.
Each refers to the vertical rail that setting is provided with support to adjustable support, and the vertical rail and support constitute sliding rail pair,
Vertical rail can be moved up and down along support.Multiple supports are installed on the vertical rail, each support constitutes the slip rail of level with vertical rail
Road pair, makes support to be slided along vertical rail level.Thus each support can rise, declines, moves to left, move to right, each by regulation
The position of individual support, can be such that the cylindrical pressure roller fixedly mounted on each support uniformly divides along the cylindrical circumferential direction of spiral welded pipe
Cloth, and can adapt to the spiral forming of different-diameter spiral welded pipe.A moveable support, the support are additionally provided with support
On be installed with inner circle pressure roller, inner circle pressure roller is located at the bottom of spiral welded pipe inwall.The cylindrical pressure roller installed on all supports
Spiral forming function is collectively forming with inner circle pressure roller.
During aluminium alloy spiral welded pipe spiral forming, delivery apparatus traction aluminum alloy plate materials, and by aluminum alloy plate materials
Being pushed to carries out spiral forming between inner circle pressure roller and cylindrical pressure roller, inner circle pressure roller is pressed on the inner periphery of aluminium alloy spiral welded pipe
Surface, each cylindrical pressure roller is pressed on the external peripheral surface of aluminium alloy spiral welded pipe, during actual shaping, due to aluminium alloy spiral welded pipe
The cross section of outer surface is unlikely to be the circle of standard, and this allows for the ball bearing contact with aluminium alloy spiral welded pipe on roller
Sometimes contact range is big, and contact range is small sometimes, and contact range hour, can be left seriously in aluminium alloy spiral welded pipe outer surface
Impression and cut, or even can enable aluminum alloy to spiral welded pipe tube wall deformation and lose justify, have a strong impact on aluminium alloy spiral welded pipe
Product quality, can actively adapt to the external surface shape of aluminium alloy spiral welded pipe at present, make roller outer surface and aluminium alloy spiral welding
Tube outer surface remains that the spiral forming device of Maximum Contact scope is still rare.
Utility model content
For deficiencies of the prior art, the purpose of this utility model is to provide for a kind of novel aluminum alloy spiral
Welded tube spiral forming device, it can actively adapt to the external surface shape of aluminium alloy spiral welded pipe, make roller outer surface and aluminium alloy
The characteristics of spiral welded pipe outer surface remains Maximum Contact scope.
In order to solve the above-mentioned technical problem, the scheme of the utility model solution technical problem is：Novel aluminum alloy spiral welding
Pipe spiral forming device, including a row inner circle pressure roller and at least six cylindrical pressure rollers of row are constituted, and the cylindrical pressure roller is along the circumferential direction
It is uniformly distributed, the inner circle pressure roller and cylindrical pressure roller are separately mounted to each on adjustable support, described inner circle pressure roller and outer
Circle pressure roller is at least fixedly mounted on wheel seat and constituted side by side by 6 rollers, and each roller is made up of wheel carrier, support shaft, bearing,
The bearing is fixedly mounted in the support shaft, and the support shaft is fixedly mounted on the wheel carrier, and the wheel carrier fixes peace
On wheel seat, described bearing is self-aligning bearing.
After using such scheme, because bearing is self-aligning bearing, thus roller is capable of the deflection of small range, and this causes roller
Can be according to the surface configuration active accommodation deflection angle of aluminium alloy spiral welded pipe, so that roller and aluminium alloy spiral welded pipe are all the time
The contact of maximum magnitude is kept, both serious cut will not be left in aluminium alloy spiral welded pipe outer surface, will not be enabled aluminum alloy to again
The tube wall deformation of spiral welded pipe and mistake are justified, and preferably ensure that the product quality of aluminium alloy spiral welded pipe.
Inner circle pressure roller is identical with the structure of cylindrical pressure roller.
The shell upper measurement of bearing is wrapped with fire resistant resin, and the cross section of fire resistant resin outer surface is round.Fire resistant resin
Play cushioning effect between the shell and aluminium alloy spiral welded pipe of bearing, the appropriate impression for mitigating aluminium alloy spiral welded pipe surface and
Cut.
Self-aligning bearing is self-aligning roller bearing.
Self-aligning bearing is self-aligning ball bearing.
Brief description of the drawings：
With reference to the accompanying drawings and detailed description to the utility model novel aluminum alloy spiral welded pipe spiral forming device
It is described in further detail.
Fig. 1 is the principle schematic diagram. of the utility model novel aluminum alloy spiral welded pipe spiral forming device.
Fig. 2 is that the structure of the roller of cylindrical pressure roller in the utility model novel aluminum alloy spiral welded pipe spiral forming device is former
Reason schematic diagram.
Specific embodiment：
In Fig. 1, Fig. 2, novel aluminum alloy spiral welded pipe spiral forming device, an including row inner circle pressure roller 2 and six arranges cylindrical
Pressure roller 1 is constituted, and cylindrical pressure roller 1 is distributed uniformly and circumferentially, and inner circle pressure roller 2 and cylindrical pressure roller 1 are separately mounted to each to adjustable
Support on (be respectively not drawn into adjustable support in figure).Inner circle pressure roller 2 is identical with the structure of cylindrical pressure roller 1.The He of inner circle pressure roller 2
Cylindrical pressure roller 1 is all fixedly mounted on wheel seat 3 and constituted (roller is only drawn in figure) side by side by 6 rollers, each roller by
Wheel carrier 4, support shaft 7, bearing 6 are constituted, and bearing 6 is fixedly mounted in support shaft 7, and support shaft 7 is fixedly mounted on wheel carrier 4, wheel
Frame 4 is fixedly mounted on wheel seat 3.Bearing 6 is self-aligning bearing.Self-aligning bearing uses self-aligning roller bearing.The shell upper measurement of bearing 6
Fire resistant resin 5 is wrapped with, the cross section of the outer surface of fire resistant resin 5 is round.Because bearing 6 is self-aligning bearing, thus the energy of bearing 6
The deflection of enough small ranges, this enables roller according to the surface configuration active accommodation deflection angle of aluminium alloy spiral welded pipe, with
Make roller that the contact of maximum magnitude is remained with aluminium alloy spiral welded pipe, will not both be left in aluminium alloy spiral welded pipe outer surface
Serious cut, will not enable aluminum alloy to the tube wall deformation of spiral welded pipe and lose justify again, and on the other hand, fire resistant resin 5 is in bearing 6
Shell and aluminium alloy spiral welded pipe between play cushioning effect, the appropriate impression and cut for mitigating aluminium alloy spiral welded pipe surface,
Preferably ensure that the product quality of aluminium alloy spiral welded pipe.
