ABSTRACT:
A shear assembly to be replaceably installed in a portable, hydraulic punch press for cutting L sectioned steel strips at, typically, 45 degrees preparatory to combining them into rectangular frames at sites of construction. The shear assembly comprises a fixed shear in the shape of a female V with an apex angle of 90 degrees, and a movable shear in the shape of a male V movable up and down past the fixed shear. Formed in fixed relation to the fixed shear is a work rest having a pair of contact surfaces with a ridge therebetween in alignment with the apex of the fixed shear. The contact surfaces of the work rest are so positioned and angled that the opposite ends of an L sectioned steel strip can be cut off into angles of symmetrical shape. An alternate embodiment is disclosed.
