Embodiment Construction

[0026] figure 1 A side view of a shearing device 1 is shown, with parts of the frame 2 omitted in order to show the shearing device more clearly. The device has a receiving device 3 on which a sheet metal stack 5 is received in the device 1 , the sheet metal stack 5 resting on a base plate 4 . Here, the sheet metal stack can be clamped by side guides and expansion magnets 6 in the area where the sheet metal is removed from the stack. Above the stack are several means 7 for removing metal sheets from the stack, which are able to release and lift the uppermost sheet metal in the stack from the stack, for example by means of the illustrated pneumatic suction cups. Such removal of metal sheets from a stack is well known and therefore will not be further described here. figure 1 Also shown in is a shearing unit 12, which in the shown case consists of a disc shear with a plurality of circular blade pairs 8 and 9. Such disc shears are also known and need not be described in detail...

Abstract

The invention relates to a cutting device for cutting stacked sheet-metal plates into sheet-metal strips using a cutting unit (12). Holding and positioning means (25 to 29 and 13 to 16) are arranged above said stack. This makes a space-saving arrangement possible while maintaining a high degree of cutting precision. The cut sheet-metal strips are fed to another cutting unit by collectively feeding all strips up to a separating point. This simplifies the feeding device and the adaptation thereof to different sheet-metal thickness.

Description

technical field [0001] The invention relates to a method for cutting metal sheets into metal strips according to the preamble of claim 1 . The invention relates to a device for shearing metal sheets according to the preamble of claim 5 . Furthermore, the invention also relates to a method for conveying metal strips according to the preamble of claim 10 and a device for conveying metal strips according to the preamble of claim 13 . Background technique [0002] It is known to cut metal sheets into strips by means of a shearing device, in particular by means of a disc shear. If the two shearing devices are arranged as crank lever shears (winkelschere), the strips cut out of the sheet metal in the first step are fed directly to the second shearer, which is also cut, for example, with a disc shear. The metal strip in the first step is cut into many metal segments respectively. When exact cut positions and high cutting precision are required for metal segments, especially in p...
