Abstract
A shearing apparatus (1) for shearing a plate member (2) is provided with a pair of shearing rollers (20, 20) opposed with each other. These shearing rollers (20, 20) are rotated in opposite directions in a state that the plate member (2) in pinched by and between peripheral surfaces of these shearing rollers (20,20). These shearing rollers (20, 20) are provided with at least one pair of shearing portions (21, 21) to be engaged with each other to shear the plate member (2). These shearing portions (21, 21) are formed on the peripheral surfaces and extend in an axial direction of the roller (20, 20).
Claims22
A shearing apparatus for shearing a plate member, comprising:
- a pair of shearing rollers (20, 20) for shearing a plate member (2) into a predetermined length while passing the plate member (2) between said pair of shearing rollers (20, 20),
- wherein said pair of shearing rollers (20, 20) are rotated in opposite directions in a state that the plate member (2) is pinched by and between said pair of shearing rollers (20, 20), and
- wherein said pair of shearing rollers (20, 20) are provided with at least one pair of shearing portions (21, 21) to be engaged with each other to shear the plate member (2), said shearing portions (21, 21) being formed on peripheral surfaces of said pair of shearing rollers (20, 20) and extending in an axial direction of each of said pair of shearing rollers (20, 20).
A method of shearing a plate member, the method includes the steps of:
- preparing a shearing apparatus (1) equipped with a pair of shearing rollers (20, 20), said pair of shearing rollers (20, 20) having at least one pair of shearing portions (21, 21) to be engaged with each other, said shearing portions (21, 21) being formed on peripheral surfaces of said shearing rollers (20, 20) and extending in an axial direction of said shearing rollers (20, 20);
- and
- shearing the plate member (2) by engaging said pair of shearing portions (21, 21) in a state that the plate member (2) is pinched by and between said shearing rollers (20, 20) rotating in opposite directions.
