Detailed description of the invention

The present invention is mainly by pinch roll body, and hydraulic shear body, transmission device, pinch roll remove The parts such as device and platform form.In order to reduce the space installed required by cutting mechanism, above cut Formula crop shears and pinch roll are designed to integral arrangement.Pinch roll/hydraulic shear under(-)chassis is welding Structural member, by studding with replaceable steel slide plate-23, the guide groove of slide plate-30 is constituted, Upper shear shank 07 for upper pinch roller carriage 04 and hydraulic shear slides up and down.Top pinch roll 05 is fastened in upper pinch roller carriage 04, and upper pinch roller carriage 04 is by being fastened thereon Slide plate-32, slide plate-31 and slide plate-23 laminating on pinch roll stand 03, so, Upper pinch roller carriage 04 is all around obtained for restriction, actually forms and play the guiding role Guide groove.Two hydraulic cylinders-01 are fixed on pinch roll stand 03, in hydraulic cylinder-01 Portion's structure is worm and gear form.Therefore hydraulic cylinder-01 both can realize linear motion function, Rotating function can also be realized.Linear motion function drives upper pinch roller carriage 04 knee-action, Thus drive top pinch roll 05 knee-action, and the opening degree of adjustable roller.Rotating function Then by lazy-tongs 12, it is ensured that the up and down motion of both sides pinch roll synchronizes.Bottom pinch roll 06 It is arranged on bottom pinch roll support 09 with hydraulic shear lower scissors seat 08, bottom pinch roll support 09 can on pinch roll stand 03 transverse shifting.09 liang of bottom pinch roll support during normal work Side is fixed on pinch roll stand 03 by bolt 29.As needed roll change or changing cutting edge, then unclamp Fastening bolt 29, is driven bottom pinch roll support 09, top by the hydraulic cylinder-13 being positioned at transmission side Go out on moving-out device framework 22, in order to change bottom pinch roll 06 and lower scissor blade 24.Hydraulic pressure Cylinder (13) one end is fixed on described pinch roll stand (03) pedestal, and the other end is fixed on On motor base (34).Slide plate-33 is fixed on pinch roll stand 03, as under pinch Roller support 09 removes the sliding surface of pinch roll stand 03.Cutting edge 24 is high intensity hardenable alloys Steel matter, is fastened on upper and lower knife rest 07,08 respectively.Bottom pinch roll 06 is solid forging Steel rider.Top pinch roll 05 is hollow roll, is cladded with stainless steel coating 25.

In order to, in the operation of rolling, band steel can pass through, under cut 08 exit and be provided with Turnover panel 15, is driven turning arm 26 to rotate by hydraulic cylinder-14, turning arm 26 and turnover panel 15 Connected as one by key 27, thus drive the rotation of turnover panel 15.When need not shear, turn over Plate 15 is horizontal, and band steel passes through.When needs shear band steel toe afterbody, liquid Cylinder pressure-14 drive turnover panel 15 be rotated into plumbness, the band steel toe afterbody stub bar cut by Turnover panel 15 breach that is vertical and that formed drops in scrap basket.This turnover panel 15 passes through bearing block 28 are fixed on pinch roll stand 03.Hydraulic cylinder-14 one end is arranged on frame 03 fore side In the support shaft in outside, the other end is connected with turning arm 26.

Upper shear shank 07 is fastened on to be cut on support 10, and two hydraulic cylinders-02 are fixed on folder Sending on roller frame 03, as top pinch roll, this hydraulic cylinder-02 internal structure is snail equally Worm and gear form, so, hydraulic cylinder-02 both can realize linear motion function, it is also possible to Realize rotating function.Linear motion function drives upper shear shank 07 knee-action, thus with under Cut and jointly complete shear action.Rotating function is then by lazy-tongs-11, it is ensured that both sides are cut The synchronization action up and down of sword, completes to shear.On cut and lean between support 10 and pinch roll stand 03 Slide plate-30 and slide plate-31, form the assembling of concave, convex shape, it is therefore an objective to play guide effect, Location, 3 directions, can only action along the vertical direction, it is ensured that above cutting support 10 can only be along guide groove Slide up and down.Bottom pinch roll 06 is by gear coupling 21, deceleration by motor-16 Machine 17 and connecting shaft-18 driven separately.Top pinch roll 05 is by motor-19 and to connect Axle-20 driven separately.
