Title:
HOOP CUTTING METHOD
Document Type and Number:
Japanese Patent JPS5775718
Kind Code:
A
Abstract:

PURPOSE: To elimiate application of any tensile force to a hoop to be cut during processing and thereby realize a precision cutting of hoops by performing the cutting while each hoop is moved in the opposite direction to movement of the moving edge and so fed into the space between the moving and stationary edges.

CONSTITUTION: Required scrap hoops are fed into the space between a stationary edge 44 and a moving edge 40 one after another while each of hoops is moved in the direction of Arrow A2, i.e. in the direction opposite to the cutting action of the moving edge 40 rotationally driven by a driver device 31. According to this arrangement, a hoop will have such a state as pushed back while the moving 40 and stationary 44 edges are conducting the cutting work and will therefore never to subjected to an attractive effect in a fashion as following the swinging and advancing motion of the moving edge 40. That is to say, not the slightest tensile force is applied to the hoop by the moving 40 and/or stationary 44 edges in service and the full accuracy provided to the automatic feed press and metal dies in use can be obtained.
