Device for breaking up chips produced by metal machining - incorporating grinding discs with adjustable shear groove width

摘要

The device consists of a conical grinding hopper (2) provided with inclined ripping blocks (3), a rotating knife head (4) with ripping (6) and corner (5) knives, and a grinding unit located below the hopper (2). The grinder is formed by a rotating shearing head (33) and at least two surrounding ring-shaped grinding discs (25,26) located on top of one another. The inner surface of these rings, which are rotatable relative to one another, incorporates equally paced shear grooves, while the shearing head is provided with shear knives (34) distributed over its circumference. USE/ADVANTAGE - In metal machining plants. In contrast to known devices, it allows the maximum break-up length of chips to be altered.
