Abstract
The invention provides a novel steekle mill pinch roll and a hydraulic shearing device. According to the structure, a hydraulic shear and a pinch roll are combined to form a whole body. As the pinch roll is adopted, strip steel is conveyed into a rolling mill, so that the strip steel can be smoothly gripped and rolled. Meanwhile, the hydraulic shear is fixed on a pinch roll rack and is used for cutting off irregular shapes of the head and the tail of the strip steel. A shearing edge moving-out device is arranged, so that upper and lower shearing edges can be conveniently replaced. The device is compact in structure and complete in function; the space is saved, and the length of a unit is shortened, so that materials are saved and the construction cost is reduced; the strip steel with better quality can be favorably rolled.

Detailed description of the invention
The present invention is primarily of pinch roll body, and the parts such as hydraulic shear body, transmission device, pinch roll moving-out device and platform form.In order to reduce the space of installing required by cutting mechanism, up cut crop shears and pinch roll are designed to integral arrangement.Pinch roll/hydraulic shear under(-)chassis is welding structural element, and by studding with replaceable steel slide plate I-23, the guide groove I of slide plate III-30 forms, and the upper shear shank 07 for top pinch roll sliding frame 04 and hydraulic shear slides up and down.Top pinch roll 05 is fastened in upper pinch roller carriage 04, upper pinch roller carriage 04 is fitted with the slide plate I-23 on pinch roll stand 03 by the slide plate II-32 that is fastened thereon, slide plate IV-31, like this, upper pinch roller carriage 04 is obtained for restriction all around, in fact forms the guide groove I play the guiding role.Two hydraulic cylinder I-01 are fixed on pinch roll stand 03, and hydraulic cylinder I-01 internal structure is worm and gear form.Therefore hydraulic cylinder I-01 both can realize rectilinear motion function, also can realize rotating function.Rectilinear motion function drives upper pinch roller carriage 04 knee-action, thus drives top pinch roll 05 knee-action, and the opening degree of adjustable roller.Rotating function, then by lazy-tongs 12, ensures that moving up and down of both sides pinch roll is synchronous.Bottom pinch roll 06 and hydraulic shear lower scissors seat 08 are arranged on bottom pinch roll support 09, bottom pinch roll support 09 can on pinch roll stand 03 transverse shifting.During normal work, bottom pinch roll support 09 both sides are fixed on pinch roll stand 03 by bolt 29.As needed roll change or changing cutting edge, then unclamp fastening bolt 29, drive bottom pinch roll support 09 by the hydraulic cylinder III-13 being positioned at transmission side, eject on moving-out device framework 22, to change bottom pinch roll 06 and lower scissor blade 24.Hydraulic cylinder III (13) one end is fixed on described pinch roll stand (03) pedestal, and the other end is fixed on motor base (34).Slide plate V-33 is fixed on pinch roll stand 03, shifts out the sliding surface of pinch roll stand 03 as bottom pinch roll support 09.Cutting edge 24 is high strength quench allov steel materials, is fastened on respectively on upper and lower knife rest 07,08.Bottom pinch roll 06 is solid forging steel rider.Top pinch roll 05 is hollow roll, outer coating stainless steel 25.
In order in the operation of rolling, band steel can pass through smoothly, under cut 08 exit turnover panel 15 be installed, drive turning arm 26 to rotate by hydraulic cylinder IV-14, turning arm 26 and turnover panel 15 are connected as one by key 27, thus drive the rotation of turnover panel 15.When not needing to shear, turnover panel 15 is horizontal, and band steel passes through smoothly.When needs shear band steel toe afterbody, hydraulic cylinder IV-14 drives turnover panel 15 to be rotated into plumbness, and the breach that the band steel toe afterbody stub bar cut vertically is formed by turnover panel 15 drops in scrap basket.This turnover panel 15 is fixed on pinch roll stand 03 by bearing block 28.Guide plate hydraulic cylinder 14 one end is arranged on the back shaft outside frame 03 fore side, and the other end is connected with turning arm 26.
On cut 07 and be fastened on and cut on support 10, two hydraulic cylinder II-02 are fixed on pinch roll stand 03, the same with top pinch roll, this hydraulic cylinder II-02 internal structure is worm and gear form equally, like this, hydraulic cylinder II-02 both can realize rectilinear motion function, also can realize rotating function.Rectilinear motion function drives upper shear shank 07 knee-action, thus with under cut and jointly complete shear action.Rotating function, then by lazy-tongs I-11, ensures the synchronization action up and down of both sides cutting edge, completes shearing.On cut by slide plate III-30 and slide plate IV-31 between support 10 and pinch roll stand 03, form the assembling of concave, convex shape, object plays guide effect, location, 3 directions, can only action along the vertical direction, and guarantee being cut support 10 can only slide up and down along guide groove II.Bottom pinch roll 06 is by gear coupling 21, reductor 17 and connecting axle I-18 driven separately by motor I-16.Top pinch roll 05 is by motor II-19 and spindle II-20 driven separately.
