Description

A kind of cutter

Technical field：

The present invention relates to a kind of sheet shearing technology.

Background technology：

Existing cutter includes being made up of upper scissors, the lower scissors of power drive, the same phase of scissors, lower scissors in drive To it is mobile be bent axle and swing arm, and upper scissors, lower scissors then move along line slideway, such a cutter, during due to shearing pair Upper scissors, direction and upper scissors, the shear direction of lower scissors of maximum force of lower scissors have certain angle, therefore, need Wanting bent axle to export larger power could meet that shearing requires, be exported due to only by a bent axle output action power and needing bigger Active force, therefore, work long hours down, bent axle easily produce fatigue and be broken, moreover, assemble when, due to there is line slideway And the influence of other corresponding auxiliary parts, assembling is complicated, is not easy to safeguard.On particularly safeguarding when scissors, lower scissors very Inconvenience.

The content of the invention：

The present invention goal of the invention be that providing one kind effectively can avoid bent axle from working long hours down, easily produce fatigue and Be broken, dismounting and cutter easy to maintenance.

The present invention is achieved in that including upper scissors, lower scissors scissors, lower scissors relatively move simultaneously in drive Actuating unit, its be particular in that actuating unit include upper bent axle group, lower bent axle group, rotational power, upper bent axle group include with What is be hinged on the right of a pair be rotatably arranged on by bearing in frame be hinged left bent axles of the upper scissors left side and upper scissors passes through axle Hold and be rotatably arranged on a pair of right bent axles in frame, a pair of the left bent axles and a pair of right bent axles of upper bent axle group are respectively positioned on same vertical On face, left crank rotation axis above a pair of left bent axles of upper bent axle group with above a pair of right bent axles of upper bent axle group The pivot center of right bent axle is on same level axis, the left crank rotation axis below a pair of left bent axles of upper bent axle group It is in the pivot center of the right bent axle below a pair of right bent axles of upper bent axle group on same level axis, the one of upper bent axle group Be respectively fixedly connected with gear at least one pair of in left bent axle and a pair of right bent axles, between two gears by respectively with two The upper idler gear linkage of gear engagement, so, a pair of left bent axles of upper bent axle group and a pair of right bent axles drive upper scissors to hang down Straight posture is swung, and lower bent axle group includes a pair be rotatably arranged on by bearing in frame left songs being hinged with the lower scissors left side What is be hinged on the right of axle and lower scissors is rotatably arranged on a pair of right bent axles in frame, a pair of left bent axles of lower bent axle group by bearing Be respectively positioned on a pair of right bent axles on same vertical plane, the left crank rotation axis above a pair of left bent axles of lower bent axle group with The pivot center of right bent axle above a pair of right bent axles of lower bent axle group is on same level axis, a pair of lower bent axle group At the pivot center of left crank rotation axis below left bent axle and the right bent axle below a pair of right bent axles of lower bent axle group In on same level axis, at least one pair of in a pair of the left bent axles and a pair of right bent axles of lower bent axle group has been respectively fixedly connected with down Gear, linked by the lower idler gear engaged respectively with two lower gears between two lower gears, so, a pair of left songs of lower bent axle group Axle and a pair of right bent axles drive lower scissors to be swung with vertical posture, and the gear below upper bent axle group is upper with lower bent axle group The lower gear engagement in face, rotational power drive upper idler gear or lower idler gear to rotate.

During work, rotational power drives upper idler gear or lower idler gear to rotate, the upper tooth below upper bent axle group Wheel engages with the lower gear above lower bent axle group, makes gear rotation direction, the lower tooth rotation of lower bent axle group of bent axle group It is dynamic in opposite direction, upper idler gear, lower idler gear transmission under, two gear synchronizations and rotate in same direction, two lower gears are same Walk and rotate in same direction, scissors, lower scissors are swung in the vertical state relatively in drive, when upper scissors, lower scissors are connected on a line When, vertically downward, and the driving force of the bent axle of lower bent axle group is vertically upward for the bent axle driving force of upper bent axle group, with required shearing Force direction overlaps, thus with the upper sheet material between scissors, lower scissors of shearing force shearing of maximum.

Compared with the prior art the present invention, is driven using double-crankshaft, therefore, can be without needing line slideway and corresponding supporting Component, influence of these components to dismounting and safeguarding is avoided, moreover, during shearing, the driving force direction and shearing force of bent axle Direction overlap, so as to be sufficiently used the driving power of bent axle, therefore, the present invention have can effectively avoid bent axle long-time work Under work, easily produce fatigue and be broken, dismounting and it is easy to maintenance the advantages of.
