Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
The generous coiled sheet thermal annealing acid washing method of a kind of stainless steel of the present invention, comprises the following steps：Stainless steel is generous
The entrance uncoiling of coiled sheet 100, welding, continuous annealing, scale breading, ball blast, pickling, smooth, outlet curling, it is in each step and adjacent
The generous coiled sheet 100 of pending stainless steel is sequentially transmitted by transport mechanism between step.
Because the generous coiled sheet thermal annealing pickling lines of stainless steel are in order to which the generous coiled sheet 100 of stainless steel is to continuous annealing acid
Wash, can will be welded into continuous generous coiled sheet then on a production line after the generous uncoiling of coiled sheet 100 expansion of stainless steel of a roll volume
Circulation, Continuous maching operation.After thermal annealing pickling operation is completed, by exporting crimp operation again by the generous coiled sheet of stainless steel
100 cut off to form generous coiled sheet independent one by one along commissure.
As shown in Figure 1 and Figure 4, in the outlet crimping procedure, what the transport mechanism included one in front and one in back setting turns
To roller 1 and jockey pulley 2.
In the outlet crimping procedure, the processing of the generous coiled sheet 100 of stainless steel is carried out using outlet device.The outlet
Equipment includes the first equipment 3 between jockey pulley 2 and slewing rollers 1 and the second equipment 4 positioned at the front of slewing rollers 1.It is described
First equipment 3 includes inspection body 6, cutting mechanism 5 and the bender 7 set from back to front.The inspection body 6 is used to check
The surface appearance of stainless steel Wide and Thick Slab.The cutting mechanism 5 is used to shear the generous coiled sheet 100 of stainless steel, by stainless steel Wide and Thick Slab
Volume 100 is separated into multiple independent stainless steel Wide and Thick Slabs, and removes the weld seam in stainless steel Wide and Thick Slab.
Second equipment 4 includes coiling machine.The coiling machine is used to separate not by the cutting mechanism 5
Become rusty steel Wide and Thick Slab rolled tubular structure.
The jockey pulley 2 rotates and can outwards send out the generous coiled sheet 100 of stainless steel.Because the position of jockey pulley 2 is arranged,
Internal stress can be formed under the effect of the flexing of jockey pulley 2 by the generous coiled sheet 100 of the stainless steel of jockey pulley 2, there is what is be bent upwards to become
Gesture.The slewing rollers 1 rotate and can be bent downwardly the generous coiled sheet 100 of stainless steel and be sent into coiling machine.
The outlet crimping procedure includes：
1）The generous coiled sheet 100 of stainless steel is pushed forward by transport mechanism.The head of the generous coiled sheet 100 of stainless steel is successively through opening
Power roller 1, inspection body 6, cutting mechanism 5, bender 7, slewing rollers 1.When the head of the generous coiled sheet 100 of stainless steel passes slewing rollers
During the first length of 1 setting, the transport mechanism stops, and first length is 40cm-50cm.The slewing rollers 1 will be stainless
The head of the generous coiled sheet 100 of steel is bent downwardly.
2）The motor reversal of the transmission mechanism, make stainless steel wide by the generous coiled sheet 100 of transport mechanism rollback stainless steel
Slab volume 100 is moved rearwards, and the generous coiled sheet 100 of stainless steel is cut off to form front and rear panels in its commissure, the foreboard position
In the front of back plate.Specifically：
2.1）The transmission mechanism antiport and transmission mechanism are operated with motor point flowing mode.Transmission mechanism drives stainless steel
Generous coiled sheet 100 retracts backward.When the weld seam of the generous coiled sheet 100 of stainless steel return back to the edge of a knife front of cutting mechanism 5 and and knife
When mouth is at a distance of the second length, the transmission mechanism stops.The cutting mechanism 5 carries out first time shearing, by stainless steel Wide and Thick Slab
Volume 100 is cut along its length is divided into front and rear panels, wherein second length is 5cm-20cm, now weld seam is in foreboard
On.
2.2）The generous coiled sheet 100 of stainless steel is continued to retract backward, when the weld seam of the generous coiled sheet 100 of stainless steel is return back to
The edge of a knife rear of cutting mechanism 5 and with the edge of a knife at a distance of three length when, the transmission mechanism stops.The cutting mechanism 5 is carried out
Second of shearing cuts weld seam from foreboard makes weld seam be separated with foreboard.3rd length is 5cm-20cm.Then, will cut
Ground weld seam bar is scaled off to take away from transmission mechanism.So, along at weld seam shearing, the afterbody of foreboard and the head of back plate are formed.
The head of foreboard and afterbody all keep smooth, are no longer upturned, meanwhile, the head of back plate also keeps smooth.
3）Front and rear panels are continued to push forward, foreboard can act on ability without such as jamming on, prizing the external force such as pressure
The subsequent treatment that the normal feeding of steel band is penetrated to progress steel band in follow-up equipment passes the first equipment 3 and slewing rollers 1 successively, enters
Enter the second equipment 4 and carry out subsequent treatment；
4）By back plate by outlet crimping procedure 1）To outlet crimping procedure 3）Operate successively.
By the generous coiled sheet thermal annealing acid washing method of above-mentioned stainless steel, the thermal annealing of the generous coiled sheet 100 of stainless steel is being carried out
When pickling is processed, what the generous head of coiled sheet 100 of stainless steel and afterbody after being sheared caused by the flexing of jockey pulley 2 tilted asks
Topic is solved.Under 1 time steering-effecting of slewing rollers, the generous coiled sheet 100 of the stainless steel of process is bent downwardly by slewing rollers 1, is eliminated
The generous head of coiled sheet 100 of stainless steel and afterbody upwarp deformation, enable the generous coiled sheet 100 of the stainless steel after shearing without
Such as jam on, the external force effect such as sled pressure just can be penetrated smoothly in follow-up process equipment, not only facilitate production, and greatly reduce
Potential safety hazard, it ensure that the safe operation of operator.
Apply specific embodiment in the present invention to be set forth the principle and embodiment of the present invention, above example
Explanation be only intended to help understand the present invention method and its core concept；Meanwhile for those of ordinary skill in the art,
According to the thought of the present invention, there will be changes in specific embodiments and applications, in summary, in this specification
Appearance should not be construed as limiting the invention.
