Description

Sheet material combined shear mechanism's structure-improved and sheet material combined shear processing method
Technical field
The present invention relates to shearing equipment and the cutting method of a kind of medium-thick plate in the Ferrous Metallurgy mechanical field, relate in particular to a kind of sheet shearing mechanism through improvement design and sheet shearing method.
Background technology
Consult Fig. 1-Fig. 2, at present in the finishing shear history of Heavy Plate Plant, generally be to be finished by the pinch roll clamping of fixation side and mobile side the plate that send of steel plate is sheared when steel plate enters shearing machine, because there is certain otherness in equipment, pinch roll roll surface wearing degree varies for example, pinch roll horizontal direction and vertical direction differ, the clamping force of fixation side and mobile side differs, manpower can't accurately be adjusted it, this just causes Plate transferring deviation (generally between 20mm~30mm) easily, and also there is uncertainty in this sideslip, surplus need be put slightly greatly when this just needed shearing steel plate, avoided causing narrow rule to cause declaring time of steel plate.Plate transferring deviation can cause steel plate easily to produce burr in shear history, and meeting Yin Maoci is pressed into and cause finishing unplanned, also can cause simultaneously later on head and tail width difference large (generally between 15mm~20mm) of subdivision plate subdivision.And be reply Plate transferring deviation and can undermine lumber recovery in the width surplus (generally between 20mm~30mm) that when operation puts steel plate, postscript, aforementioned factor also can make the wrong cutter of shearing steel plate, causes the interface projection obviously to need manually carry out in a large number reconditioning.
Summary of the invention
The object of the present invention is to provide a kind of sheet material combined shear processing method and sheet material combined shear mechanism structure-improved, in order to solve the sideslip problem in the steel plate shearing process, and then the shearing quality of raising steel plate, reduce the excessive and loss that causes of steel plate surplus, thereby overcome deficiency of the prior art.
For achieving the above object, the present invention has adopted following technical scheme:
A kind of sheet material combined shear processing method comprises:
Combined shear mechanism is provided, comprises that bilateral scissors and subdivision cut;
At least pressure roller more than a group is being set before the entrance of described bilateral scissors;
And, in the steel plate shearing process, by described more than one group a group in pressure roller and the described combined shear mechanism clamp simultaneously steel plate with top pinch roll, prevent the steel plate whipping and sideslip, and utilize described combined shear mechanism that steel plate is sheared.
A kind of sheet material combined shear mechanism structure-improved, comprise that bilateral scissors and subdivision cut, and also be provided with pressure roller more than a group before the entrance of described bilateral scissors at least, be used in steel plate shearing process and combined shear mechanism one group and cooperate the clamping steel plate with top pinch roll, prevent the steel plate whipping and sideslip.
Say that further described pinch roll comprises entrance side pinch roll and the outlet side pinch roll that sets gradually along the direction of feed of steel plate.
Described outlet side pinch roll comprises that one group of bilateral scissors outlet side pinch roll and one group of subdivision of setting gradually along the direction of feed of steel plate cut the outlet side pinch roll.
As one of better embodiment, the driving mechanism of described one group of above pressure roller be connected one group of driving mechanism with top pinch roll and all be connected with a control module, and controlled by described control module.
Described driving mechanism comprises cylinder, but is not limited to this.
As one of better embodiment, described pressure roller is distributed in the shear line roller-way zone, and can be under the driving of drive unit with shear line roller-way zone in corresponding roller-way cooperate the clamping steel plate.
Compared with prior art, advantage of the present invention is at least: thus participate in making up the purpose that the shearing of cutting has realized avoiding Plate transferring deviation by setting up pressure roller before cutting in combination, it is simple in structure, easy to implement, but and the quality of Effective Raise steel plate and yields, produce distinct economic, simultaneously, the steel plate of producing need not the reconditioning of rolling off the production line, and has reduced Field Force's labour intensity and on-the-spot potential safety hazard.
