'Orifice plate with integrated form-level for sets of preferably after the wolf tool - principle operating cutting machines'

摘要

The present invention relates to the design of the knives for preferably after the wolf tool - principle of cutting machines which operate with the aim of the increase in performance and quality improvement.The perforated disc (1) receives, from one side (2), as usual, with the insertion depth a (7) of vertically extending straight bores (3). From the opposite side (2), in the region b (8) in the angle α (5) of less than 90 degrees to the vertical obliquely extending bores (6) is introduced. Thus, this results in a bend (4) in the bore by means of gear. This kink (4) increases the stability and vibrations are avoided as far as possible, as well as deformations during of the separation process, prevents. In the sequence will improve the shearing off effect occurs of the knife, because the cutter blades continuously to the hole disks surface, can lie.Depending on the preferred installation, the raw material inlet and / or the raw material outlet either on the perforated disks side (2) with the vertical bores (3), or also on the side with the diagonal bores (6) can take place.The angle α (5), the insertion depth a (7) of the straight bores and the area b (8) of the inclined bores can be in a function of the state of the raw material to be processed are selected. In this case, the ratio of the length a (7) of the elongated hole bore (3) to the region b (8) of the course of the oblique bore (6) between 1: 1 to 3: 1.
