Detailed description of the invention
To schematically disclose multiple embodiments of the application, as clearly stated, many practices below
On details will be explained in the following description.It should be appreciated, however, that the details in these practices is not
Application is to limit the application.It is to say, in the some embodiments of the application, in these practices
Details is non-essential.Additionally, for simplify graphic for the sake of, some known usual structures and assembly are at figure
Formula will illustrate in the way of simply illustrative.
Refer to Fig. 1, for the schematic diagram of the plate drawing machine draw-off gear 1 of the application one embodiment.Such as figure
Shown in, this application provides a kind of plate drawing machine draw-off gear 1, it sequentially arranges blowing module 10, aligning
Module 11, lubrication module 12, drawing module 13, lubrication module 14 and rewinding module 15.Put
Material module 10 includes that discharge plate 101, pipe embryo are wound in discharge plate 101, and supply pipe embryo is to aligning module
11.Aligning module 11 is three-roll unbender or aligning wheels, and wherein three-roll unbender has three alignings
Roller, three aligning rollers can be respectively convex roller or recessed roller.Seeing also Fig. 2, it is that the application one is real
Execute the schematic diagram of the aligning module 11 of mode；As it can be seen, the application uses aligning wheels 111, aligning
Wheels 111 have multiple upper aligning wheels 112 and multiple lower aligning wheel 113, multiple upper aligning wheel 112 water
Putting down and be spaced, multiple lower aligning wheel 113 horizontal intervals are arranged in the lower section of multiple upper aligning wheel 112,
Multiple upper aligning wheels 112 are staggered with multiple lower wheels 113 of aligning, i.e. upper aligning wheel 112 correspondence two
Interval between lower aligning wheel 113.The pipe embryo multiple upper aligning wheel 112 and multiple by aligning module 11
Between lower aligning wheel 113, pipe embryo is aligned by multiple upper aligning wheels 112 and multiple lower aligning wheel 113,
And drive pipe embryo to move toward lubrication module 12.
Seeing also Fig. 3, it is the schematic diagram of lubrication module 12 of the application one embodiment；Such as figure
Shown in, lubrication module 12 includes the first oil-way 121 and is positioned at above the first oil-way 121
First lubricating oil supply part 122, corresponding first oil-way 121 of the first lubricating oil supply part 122.
When pipe embryo enters the first oil-way 121, the first lubricating oil supply part 122 supplies lubricating oil to
One oil-way 121, the surface of the pipe embryo being positioned at the first oil-way 121 is coated with lubricating oil.With
Aligning module 11 continued operation, drive the pipe embryo being positioned at oil-way 121 toward before drawing module 13
Enter.Drawing module 13 is drawing mould, and the two ends of drawing mould are respectively inlet and outlet, its import
First oil-way 121 of corresponding lubrication module 12.When pipe embryo enters the import of drawing mould, drawing
Mould carries out drawing to pipe embryo, changes the caliber of pipe embryo, from the pipe embryogenesis tubing of the outlet of drawing mould.
Tubing enters lubrication module 14 afterwards, sees also Fig. 4, and it is the application one embodiment party
The schematic diagram of the lubrication module 14 of formula；As it can be seen, lubrication module 14 have cooler 141,
Second oil-way 142 and the second lubricating oil supply part 143, cooling bath 141 is arranged at drawing mould
The side of outlet, the second oil-way 142 is positioned at the side of cooler 141, and with drawing mould pair
Should, the second lubricating oil supply part 143 is arranged at the top of the second oil-way 142, and corresponding second
Oil-way 142.Cooler 141, cooler 141 is first passed through from the outlet of drawing mould tubing out
Reduce the temperature of tubing.Then tubing enters the second oil-way 142, the second lubricating oil supply part 143
Supply lubricating oil is to the second oil-way 142, and tubing is soaked in the lubricating oil of the second oil-way 142,
And make the surface of tubing be coated with lubricating oil.
Wherein cooler 141 can be blower fan, by cold front heavy rain from the outlet of drawing mould tubing out；
Cooler 141 is alternatively chilled(cooling) water supply (CWS) parts, by cooling water cooling from the outlet of drawing mould out
Tubing, now need to be provided with cooling bath below cooler 141, cooling water accepted by cooling bath.From drawing
The temperature of the tubing that mould pulls out is the highest, and tubing can reduce pipe through lubrication module 14 cooling
The temperature of material, carries out secondary lubrication to tubing simultaneously.
Again refering to Fig. 1, then rewinding module 15 includes drawing cylinder 151, drive disk assembly 152, drive division
Part 153 and rewinding dish 154, drawing cylinder 151 is arranged at the side of lubrication module 14, driving section
Part 152 connects one end of drawing cylinder 151, and driver part 153 connects drive disk assembly 152.Rewinding dish
The lower section of 154 other ends being positioned at drawing cylinder 151, and relative with driver part 153.Driver part
153 drive drive disk assembly 152, and drive disk assembly 152 drives drawing cylinder 151 to rotate.Tubing is along with drawing
Cylinder 151 rotates and is wound on drawing cylinder 151, also drives simultaneously and is advanced by the tubing of drawing mould.
The tubing being so wound in drawing cylinder 151 comes off on rewinding dish 154.Previously lubrication module 14 was
First cooling down the tubing being wound in drawing cylinder 151 and secondary lubrication, such tubing twines expects in drawing cylinder
When 151, reduce the frictional force between tubing and drawing cylinder 151, it is to avoid the surface of tubing produces the shape of viscous aluminum
Condition, avoids tubing to rupture during high speed drawing simultaneously, not only improves production efficiency, also ensure
Product quality, increases yield rate.
In sum, the plate drawing machine draw-off gear of the application is mainly cooled down from drawing by lubrication module
The tubing that module pulls out, and lubrication module carries out secondary lubrication to the tubing after cooling, fall
Frictional force between low tubing and drawing cylinder, effectively prevents the surface of tubing from gluing aluminum, avoids tubing in height simultaneously
Rupture during speed drawing, not only improve production efficiency, also ensure that product quality, increase finished product
Rate.
Described above illustrate and describes some preferred embodiments of the present invention, but as previously mentioned, it should reason
Solve the present invention and be not limited to form disclosed herein, be not to be taken as the eliminating to other embodiments,
And can be used for various other combination, amendment and environment, and can in invention contemplated scope described herein,
It is modified by above-mentioned teaching or the technology of association area or knowledge.And those skilled in the art are carried out changes
Move and change is without departing from the spirit and scope of the present invention, the most all should be in the protection of claims of the present invention
In the range of.
