Description
Technical field
The present invention relates to a kind of hand-held electric shear, particularly a kind of novel hand-held electric shears with adjustable shearing force.Belong to the hardware ﹠ tools technical field.
Background technology
In sheet metal manufacturing technology field, leather processing technical field, often need cut out raw material sheet iron and leather.At present, it is to adopt hand tools basically that above-mentioned material is cut out used material, or fixed motor machine cutter.Not only working strength of workers is bigger to adopt hand tools, its production efficiency is also lower simultaneously, though and fixed motor machine cutter can alleviate working strength of workers, raise labour productivity, but because this kind equipment volume is bigger, not only the cost of equipment is higher, especially owing to move inconvenience, the use of incompatibility production scene needs.
Summary of the invention
The objective of the invention is to: a kind of novel hand-held electric shears with adjustable shearing force is provided, so that in sheet metal manufacturing technology field, leather processing technical field, during raw material sheet iron and leather cut out, raise labour productivity, reduce labor strength, adapt to the use needs of production scene.
Solving the technical scheme that its technical problem adopts is: a kind of novel hand-held electric shears with adjustable shearing force, it is made up of scissors body, roller, motor, one-level gear, secondary gear, tertiary gear, level Four gear, level Four gear gyroaxis, eccentric shaft, connecting rod, bearing, elastic collar, bearing pin, locking nut, cutting blade, fixed blade, fulcrum shaft, button, fork, lead etc.Described scissors body is made up of two of symmetry, a cavity is arranged in the centre of two scissors bodies, in the cavity of the centre of two scissors bodies, installing and fixing motor, the one-level gear is installed above the output shaft of motor, described one-level gear and secondary gear are formed meshing relation, secondary gear and the coaxial fixed installation of tertiary gear, level Four gear and eccentric shaft are fixed on above the level Four gear gyroaxis simultaneously, form meshing relation between tertiary gear and the level Four gear.One end of described connecting rod is installed on the eccentric shaft, an other end is fixed on above the bearing pin by bearing, have flange in the middle of the described bearing pin, one end face of flange and the slotted hole end face on the fork are close together, an other end face of the slotted hole on fork is fixed on bearing pin in the slotted hole on the fork with nut.Region of interest at described scissors body, have inwardly recessed opening, bottom at opening installs and fixes blade with screw, described fork is 7 word shapes, the toggle position of fork is hinged with fork and scissors body with fulcrum shaft, region of interest at fork installs and fixes cutting blade with screw, and cutting blade and fixed blade are formed the cutting edge of electric shear.To the control of electric shear, in the appropriate location, top of scissors body press button is installed for convenience, lead is fixed on one's body the scissors through elastomer connector, and two contacts of lead and switch are connected to form the closed-loop path.For the ease of moving of hand-held electric shear, the roller of right quantity is installed in the position suitable in the bottom of scissors body.
Operation principle of the present invention is: motor drives one-level gear rotates, the one-level gear drives secondary gear, tertiary gear, the rotation of level Four gear successively, because there are certain off-centre in self axis of eccentric shaft and the axis of level Four gear, so, under the drive that the level Four gear rotates, connecting rod is swing just, and the swing of connecting rod drives the swing of fork again, so form the action of shearing between cutting blade and the fixed blade.Regulate the diverse location of bearing pin in the slotted hole of fork,, just changed the size of the arm of force of lever according to lever principle, so, play the effect that changes shearing force, to adapt to different requirements of shearing technology and shearing force.
Beneficial effect: the present invention is owing to adopt the relevant mechanical mechanism of motor-driven, realize the shear action of moving shear blade and fixed blade sheet, simultaneously, because driving the application of force arm of force of the fork of blade action can regulate, thereby can change the shearing force of electric shear, so the present invention not only can alleviate working strength of workers, raise labour productivity, the use needs that adapt to the production scene can also adapt to different requirements of shearing technology and shearing force simultaneously.
