Cut-off machine

摘要

The subject matter of the invention is a cutter designed to make pieces from different materials; it is equipped with two computer numerical controlled tools from one controller making it possible to create one piece using water or plasma cutting technology. The cutting machine contains a portal (1) with a slidably mounted tool rest carriage on the crosswise track for attaching the waterjet head (4), and a tool rest carriage for attaching the plasma cutting torch (5). Each tool rest carriage is fitted with a separate drive unit. In addition, the cutting machine is equipped with a tub (6), with a grid (7) inside the tub and a slatted grille (8), which form a work table, and two units - one designed for creating and shaping the stream of water, while the other one for creating and shaping plasma; the CNC controller is equipped with software that allows the control of two cutting tools while making one piece and all operations which take place in the process of cutting, i.e. the movement of tools and cutting parameters. The tub (6) is an open top tank, comprising a main tank (9), and a separator (10). The bottom (13) of the main tank (9) is flat and placed horizontally, and the separator's (14) bottom is slant. The bottom of the separator (14) is fitted with a screen (16) and a throat (17) with an adjustable lid (18), preferably in the form of a drainage screen, which constitutes two stages of waste segregation. The tub (6) is also equipped with a cleaning system and a water level control device. The cleaning system includes: a scraping strip (19) which is formed by a series of scraper elements (24), which move the waste collected at the bottom of the main tank (9) through the bottom of the separator (14), the screen (16) into the throat (18), and from here outside to the waste tank.
