Embodiment Construction
[0092] figure 1 and figure 2 A shearing device with counter-rotating drums known to the applicant according to the prior art is illustrated.
[0093] The purpose of this shearing device 1' is to shred scrap, especially metal strips such as edge scrap, into pieces. The device 1' comprises two counter-rotating drums 2', 3' placed facing each other, the rotation axes of the drums being substantially parallel.
[0094] A drive device (not shown) is connected to the drums and synchronizes the rotational speed of said drums.
[0095] The device 1' comprises at least one pair of blades 20', 30'; 21', 31'; 22', 32'; 23', 33' (more specifically, four pairs of blades), consisting of two rollers 2', 3' carries each pair of blades 20', 30'; 21', 31'; 22', 32'; 23', 33' respectively, and the purpose of the pair of blades is to cut Work together to cut waste.
[0096] Such as Figure 2a As shown, starting from the cutting edge 4' of said blades, the pair of blades have flat faces 5',...

Abstract
The invention relates to a shearing device (1) for comminuting metal strip comminution, said device comprising two counter-rotating drums (2, 3) placed facing each other, connecting the drums and allowing the rotation of said drums a speed synchronous drive device, and at least one pair of blades carried by the two drums (2, 3) respectively, the purpose of which pair of blades is to cooperate by shearing action during the rotation of the drums (2, 3) so that Cutting waste, starting from the cutting edge (4) of this blade, the pair of blades have flat faces called overlapping faces, which overlap each other at least partially and face each other during shearing between the blades, each The blades are all attached transversely to the drum (2, 3), at an angle relative to the drum's (2, 3) axis of rotation (A1, A2) and such that the plane passing through the overlapping faces of the blades is aligned with the respective drum's axis of rotation (A1 , A2) form a certain angle, thereby causing progressive shearing. According to the invention, said overlapping face of each blade (20; 30; 21; 31; 22, 32; 23, 33) is inclined relative to the corresponding roller (2, 3), thereby enabling the The planes of the faces do not intersect the axis of rotation of the drum (2, 3) over the effective width of the drum.
Description
technical field [0001] The present invention relates to a shearing device for the purpose of comminuting waste, more specifically metal strips, into fragments. [0002] The field of the invention is that of rotary shearing devices for breaking up edge scrap into multiple pieces in lines for processing metal strip, such as rolling mills. Background technique [0003] During operations for processing metal strips, it is known to cut the edges of the metal strip in order to obtain a desired width of the strip. This operation is usually carried out by means of pairs of cutting discs which, during the movement of the strip, cut the strip close to the edge in the direction in which the strip moves forward. [0004] The cut-to-size strip continues to move forward on the line, while each strip cut off, known as "edge scrap", is diverted and led out of the line. Document US2417556 describes such a cutting device with a cutting blade. [0005] The tape is scrap that can be wound on...
