Profiled sheet metal shear - has pivoting blades cutting along particular edges under magnetic force

摘要

The profiled sheet metal shear has two fixed and two pivot mounted blades. The pivot mounted blades are so arranged as to cut along particular edges. One of the moving blades can make internal cut of a pipe under the action of a magnetice force. There can be an outer and an inner blade both on the fixed and moving sides. Components fixed to the table can be arranged to slide in lenghtwise grooves to vary the length of the profiled sections to be cut. The design allows shearing to take place with the minimum amount of distortion of the work.
