Abstract
The shearing machine is designed to surely shear an object to be sheared with less amount of power without causing slips. A plurality of lower shear blades mounted on a lower jaw member are arranged such that the arrangement of the cutting edges forms a convexity curved downward. The front edge portion of each shear blade inwardly protrudes from an adjacent rear edge portion of each forward adjacent shear blade. A plurality of upper shear blades mounted on an upper jaw member are arranged such that the arrangement of the cutting edges forms a convexity curved upward. The front edge portion of each shear blade inwardly protrudes from an adjacent rear edge portion of each forward adjacent shear blade.
Claims12
A shearing machine comprising:
- a shearing machine body having a pair of jaw members rotatably connected with each other so as to open and close like scissors;
- a plurality of shear blades arranged in series on each occluding portion of said jaw members;
- a bracket for rotatably supporting said shearing machine body, said bracket being attached to an arm of a work machine;
- wherein said shear blades mounted on said each jaw member are arranged such that the arrangement of cutting edges of said shear blades forms a convexity curved in an opening direction of said jaw members with the front edge portion of at least one of said shear blades inwardly protruded compared to an adjacent rear edge portion of one of said forward adjacent shear blades.
A shearing machine comprising:
- a shearing machine body having an upper jaw member rotatably connected to a lower jaw member so as to open and close like scissors, said lower jaw member having a leading edge portion arranged on an open and close trajectory of a leading edge portion of said upper jaw member, said lower jaw member being divided into two parts so as to fit a leading edge portion of said upper jaw member therebetween, wherein upper nose faces of said two parts are arranged on a common flat plane;
- a plurality of shear blades arranged in series on each occluding portion of said upper and lower jaw members;
- a bracket for rotatably supporting said shearing machine body, said bracket being attached to an arm of a work machine;
- wherein said shear blades mounted on said upper and lower jaw members are arranged such that the arrangement of cutting edges of said shear blades forms a convexity curved in an opening direction of said jaw members with the front edge portions of said shear blades inwardly protruded compared to an adjacent rear edge portion of said any adjacent forward one of shear blades.
