The specific embodiment
The utility model is a kind of double coreless feeding type Coil Box.The Coil Box working method is divided into batches and handover state and pass-through state.
Like Fig. 1, Fig. 2, shown in Figure 3, the utility model comprises inlet roller apron 1, bending roll device 2, roll coil of strip forming rolls 3, roll coil of strip cradle roll 4, centralising device 5, uncoiling mechanism 6, goes up and down to transfer roller-way 7 and anti-tipping attemperator 8.
Inlet roller apron 1, bending roll device 2, roll coil of strip forming rolls 3, roll coil of strip cradle roll 4 and the handover roller-way 7 that goes up and down are located on the frame successively, and the adjustment of each several part is by Driven by Hydraulic Cylinder;
Inlet roller apron 1 comprises roller frame, roller and guide plate, and inlet roller apron 1 is gone up and down by Driven by Hydraulic Cylinder, and hydraulic cylinder is hinged on the frame.
Bending roll device 2 comprises that two are gone up bending roll and a following bending roll, and last bending roll places the top of the guide plate of roller apron 1, and following bending roll is fixed on the frame; The said hydraulic cylinder of going up the bending roll connection has displacement transducer.
Roll coil of strip forming rolls 3 is arranged on the below of bending roll device 2, and roll coil of strip forming rolls 3 is gone up and down by Driven by Hydraulic Cylinder.
Roll coil of strip cradle roll 4 comprises two carrying rollers, and a carrying roller is installed on the frame, and another root carrying roller is installed on the liftable swinging mounting by Driven by Hydraulic Cylinder, and swinging mounting is hinged on the frame.Swinging mounting can make roll coil of strip swing, uncoiling and transfer through lifting hydraulic cylinder.
Centralising device 5 is positioned at the top of roll coil of strip cradle roll 4.Centralising device 5 is made up of two flipper guides, is installed in roll coil of strip cradle roll top, and two flipper guides are controlled by two hydraulic cylinders that are fixed on gantry operation side and transmission side respectively, are used for the centering roll coil of strip and concordant roll coil of strip end.
Lifting moving roller-way 7 is made up of the some grooved rollers that gone up and down by Driven by Hydraulic Cylinder.When the roll coil of strip is transferred, go up and down to transfer the lifting hydraulic cylinder bottom of roller-way 7 through its below, make things convenient for passing through of the roll coil of strip; When intermediate blank 11 is passed through, go up and down to transfer roller-way 7 and arrive horizontal level through the lifting hydraulic cylinder jacking of its below, be convenient to intermediate blank 11 and directly pass through.
The course of work of the utility model:
1, batch and the handover state:
The jacking hydraulic cylinder jack-up of inlet roller apron 1 both sides makes roller frame, roller, the guide plate of inlet roller apron 1 all be promoted to the operating position that Coil Box comes into operation, and formation can guide intermediate blank 11 to import the inlet slot of roll gap between the upper and lower bending roll.Bending roll device 2 is according to intermediate blank 11 thickness; Last bending roll regulates automatically the gap values between rollers of upper and lower bending roll through the hydraulic cylinder of coupled band displacement transducer; Intermediate blank 11 is after inlet roller (guide) apron 1 gets into bending roll device 2; Intermediate blank 11 heads form original curved curvature, and these intermediate blank 11 head impact are adjusted to the roll coil of strip forming rolls 3 that batches the position and can be formed involute by hydraulic cylinder.Increase with the volume footpath, under the gravity effect, the roll coil of strip that intermediate blank 11 forms will contact with a carrying roller that is fixed on the frame in the roll coil of strip cradle roll 4; When the volume footpath increases to certain value; The roll coil of strip is along with the skew of center of gravity; To be fixed on the swinging mounting and with another root and contact, and along with the further increase in volume footpath, swinging mounting finishes until batching to lower swing to the carrying roller that batches the position by hydraulic cylinder jacking.
The centralising device 5 that in coiling process, is fixed on the frame both sides carries out short stroke according to roll coil of strip width to be adjusted automatically, guarantees that the section on roll coil of strip both sides is smooth, after batching completion, opens automatically.After the roll coil of strip batches end; Under the effect of roll coil of strip cradle roll 4, roll coil of strip afterbody is in the uncoiling ready position, and this moment, the revoliving arm of uncoiling mechanism 6 rotated; Make the uncoiling cutter along roll coil of strip outer ring slide and insert take the lead and the roll coil of strip between the slit; Roll coil of strip cradle roll 4 drives roll coil of strip counter-rotating, and the roll coil of strip is opened, and makes its afterbody become head and gets into pinch roll.Finish batching with uncoiling of first station 9 this moment.
Roll coil of strip remainder is under the pulling of F1 milling train, and the up-down that is provided with anti-tipping attemperator 8 along both sides and has been in transmitting place is transferred roller-way 7 and arrived second station 10 and continue uncoilings, and first station 9 has been in this and has connect volume state.
2, pass-through state:
The jacking hydraulic cylinder of inlet roller apron 1 both sides falls, and makes roller frame, roller, the guide plate of inlet roller apron 1 all drop to feed-through locations.Roll coil of strip forming rolls 3 drops to feed-through locations in the effect of hydraulic cylinder.Roll coil of strip cradle roll 4 is under the effect of hydraulic cylinder, and swinging mounting falls, until being in feed-through locations.Go up and down to transfer roller-way 7 jacking hydraulic cylinder jack-up, until being in feed-through locations.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
