Abstract
The invention provides a kind of desirable strong shears.Its main feature is to adopt lever and the eccentric shaft link gear driving member as power, and two cut body one end links to each other by hinge, and the other end is equipped with movable blades, and two cut the body middle part links to each other by eccentric shaft, gusset piece, bearing pin.The increase ratio of this kind strong shears power is big, and the blade of pincers sword is replaceable, and the shearing adjustable included angle of two pincers swords is whole, thereby not only can shear wire rod, also can shear various section bars such as sheet material, angle steel.Compare with existing bolt clipper, it is big to have shearing force, and long service life can be sheared various section bars, and the is easy to operate remarkable advantage of Denging.
Description
The invention belongs to hammer-shears cutting tool technical field, is a kind of strong shears.
Existing bolt clipper is to adopt the driving member of secondary lever linkage structure as power, line of action of force is vertical with the arm of force in the leverage for the first time, the performance of power is effective, and in the leverage for the second time, because line of action of force and arm of force out of plumb form component, the scaling up of power is less, the performance weak effect of power, and shearing force is little; Because cutting edge is the line contact, so can only shear single wire rod; Because two of composition bolt clipper is cut body and all is to cut body, need the reinforcing of symmetrical equilibrium simultaneously of operator's both hands in therefore using, operation easier is big, the easy breakdown of pincers sword; Because the pincers sword is an one with cutting body, cause bolt clipper integral body to be scrapped again, shortened the service life of bolt clipper.
The purpose of the invention is that a kind of shearing force of design is big, and long service life can be sheared various section bars, easy to operate strong shears.
The main technical schemes that the invention is taked is improved existing bolt clipper, adopt lever and eccentric shaft link gear to replace the driving member of original secondary lever linkage structure as power, two moving cutting between the body connect by locating hinge, at a moving middle part of cutting body eccentric shaft is set, eccentric shaft one end is equipped with handle, the one moving body middle part of cutting links to each other with another moving middle part of cutting body by eccentric shaft, gusset piece, and will clamp sword and change movable blades into, moving cut the body bottom surface base is set at another, thereby constitute a kind of strong shears.
The invention provides a kind of desirable strong shears for hammer-shears cutting tool technical field.Because this kind strong shears has adopted lever and the eccentric shaft link gear driving member as power, line of action of force is vertical with the arm of force in leverage, the performance of power is effective, at eccentric shaft on, change power is the curved wedge surface effect, form reinforcing gradually, the increase ratio of power is big, thereby has improved shearing force; Because will clamp sword changes movable blades into, thereby the blade of replaceable breakdown cutting edge, prolonged the service life of cutting nipper, and can adjust the angle of cutting edge, with cutting edge is line contact a becoming contact, make it reach shearing force and concentrate, thereby not only can shear wire rod, also can shear various section bars such as sheet material, angle steel; Because another is moving cuts body and is provided with base and can cuts body and firmly become the motionless body of cutting another of this cutting nipper is moving, be beneficial to both hands and make a concerted effort in a fixed handle or only need one-handed performance, can reach firmly balanced, shear steady purpose.Compare with existing bolt clipper, it is big to have shearing force, and long service life can be sheared various section bars, remarkable advantage such as easy to operate.
Reach the specific structural features that example further specifies the invention strong shears in conjunction with the accompanying drawings.
Accompanying drawing is represented the structural representation of the invention strong shears.
Referring to accompanying drawing, the invention strong shears comprises: move and cut body 3, handle 1 moves and cuts body 6, handle 7, eccentric shaft 2, locating hinge 4, gusset piece 10, bearing pin 11, base 8, fastening bolt 9, movable blades 5, screw 12,13.A moving end of cutting body 3 is contained in moving cutting on the body 6 by locating hinge 4, movingly cuts body 3, the moving other end of cutting body 6 respectively is equipped with movable blades 5 by screw 12,13.The moving body 3 of cutting passes through eccentric shaft 2 with moving middle part of cutting body 6, gusset piece 10, bearing pin 11 links to each other, eccentric shaft 2 is the coaxial eccentric shaft of one or two end-journal, the moving body 3 of cutting is contained on the eccentric shaft 2 on the axis body with one section of axle journal eccentric axis, and two gusset pieces, 10 1 ends are contained on the axle journal of eccentric shaft 2, and the other end is contained in moving cutting on the body 6 by bearing pin 11, one end of handle 1 is contained on the axle journal of eccentric shaft 2 one ends, and an end of handle 7 is contained in moving cutting on the body 6.Base 8 is contained in moving bottom surface of cutting body 6 by fastening bolt 9, and base 8 can be reversed into the moving center line of cutting body 6 perpendicular or parallel.
Two hands inwardly firmly act on handle 1, handle 7 respectively during use, eccentric shaft 2 rotates thereupon, moving cut body 3 and move down around locating hinge 4, driving gusset piece 10 simultaneously is center of circle swing with bearing pin 11, the action direction of power is by the vertical curved wedge surface that becomes with the arm of force, when cutting body 3 and being displaced downwardly to blade and moving the blade of cutting on the body 6 and overlap, promptly finished shear history when moving one time.Otherwise, on raise one's hand handle 1 drive moving cut to move on the body 3 be returned to original position.When needs are sheared sheet material or angle steel, take out screw 12, loosening screw 13 is moved blade 5 and is moved down adjustment around screw 13; Two moving cut the body cutter and form suitable shearing angle, tighten two screws 12,13 then.Owing to change the line contact for the some contact, increased the shearing force of unit are, thereby can shear wire rod, sheet material, various section bar.In case of necessity, band base moving cut that body lands or two supporting-points of base 8 is reversed into moving and cut the perpendicular shape of body 6 center lines, be beneficial to steadily land, but therefore both hands makes a concerted effort to increase active force or have only a hand operated firmly in an arm of force, vacate the another hand.
