Embodiment Construction

[0019] figure 1 The shearing machine 1 according to the invention is shown in perspective illustration. The shearing machine 1 includes an upper knife rest 2 and a lower knife rest 3 . An upper knife 2 a and a lower knife 3 a are installed at the upper knife rest 2 and the lower knife rest 3 . The upper knife rest 2 can move relative to the lower knife rest 3 . For this purpose, two hydraulic cylinders 4 are mounted on the lower tool carrier 3 , wherein corresponding piston rods 5 of the hydraulic cylinders 4 are connected to the upper tool carrier 2 . Through the control of the hydraulic cylinder 4, the upper tool rest 2 can move up and down relative to the lower tool rest 3, that is, along the figure 1 Movement in the direction of the arrow z shown in.

[0020] figure 2 Shown in side view from the front figure 1 The shearing machine1. This means that the lower tool holder 3 serves as a receiving element for the two hydraulic cylinders 4 . When the hydraulic cylinder...

Abstract

A shear, in particular a cross-cutting shear, for cutting flat material, including a upper blade support and a lower blade support, at least the upper blade support or the lower blade support being reciprocatingly displaceably guided and being displaceable by at least one adjustment device relative to the other respective blade support. The displaceable blade support is guided by the adjustment device and the adjustment device is designed so that it absorbs all the cutting forces and transversal forces.

Description

technical field [0001] The invention relates to a shear for cutting flat material according to the preamble of claim 1 . Background technique [0002] In the discontinuous or continuous production of strips or plates produced, for example in rolling (hereinafter referred to as flat material), it is known to divide the flat material into manageable pieces for further processing. A dividing device, for example in the form of a shear, is used for this purpose. [0003] In shearing machines, the cutting gap generally has an optimal specific value for a defined material with a predetermined thickness. In order to cut cleanly, the cut gap must remain constant throughout the cut path. That is to say, the cutting gap should not become larger due to the generated forces, since otherwise the quality or quality of the cut would not be satisfactory and the wear of the tool would increase. [0004] In order to avoid changes in the cutting gap, guide elements are used which allow movem...
