Problems solved by technology

[0008] A disadvantage in known shearing machines according to the prior art is the sliding friction that exists between the moving upper blade holder and the guide, which, in addition to heating the guide surface, also leads to contamination due to abrasion
The result is a reduced service life of the guided components as well as the guide

Embodiment Construction

[0022] figure 1 The illustration in FIG. 2 depicts an upper tool holder 312 driven via a crankshaft 350 with a slide 320 at which a first tool 322 is fixed. Furthermore, a fixed lower tool holder 313 with a second tool 323 is arranged. The slides 320 of the upper tool carrier 312 are guided in corresponding slide guides 330 . The slide element 300 and the cooling means 205 are arranged between the slide 320 and the slide guide 330 . The cutting process is described as a force triangle, in which the resultant separating force (cutting force) is formed by the vertical component force and the horizontal component force (occlusal pressure (Kaudruck)) composition. The occlusal pressure is here transmitted via the upper tool carrier 312 and the slide element 300 to the carriage guide 330 . In order to stabilize the upper knife holder 312 and to press the upper knife holder 312 against the slide element 300 during the positioning of the knife holder against the cutting object and...

Abstract

The invention describes a guide device (1000) for a knife (322) having a slide (320) for receiving a knife (322) and a slide guide (330) and a slide The sliding element (300) between the seat guide (330) and the sliding seat (320). A cooling device (205) is arranged for cooling the sliding element (300). The cooling device ( 205 ) is here designed as at least one closed cooling channel ( 210 ) or as an open cooling channel ( 209 ) with at least one inlet ( 215 , 216 ) and outlet ( 215 , 216 ) for the coolant.

Description

technical field [0001] The invention relates to a guide device for a tool with a slide for accommodating a tool and a slide guide and a slide element between the slide guide and the slide. Background technique [0002] From DE 2122855 is known a linearly guided movable upper knife slide which is arranged in a shearing machine for edge trimming of sheet metal. [0003] Document DE 1502980 describes a flat knife edge trimmer (Flachmesser-Saumschere) with a driven upper knife beam which is guided on the machine frame over the entire movement process. The upper tool beam is connected via a shaft to a carriage which is guided on two wedge-shaped slides. The slide is in turn connected to the device in order to adjust the cutting gap accordingly. [0004] From DE 1502870 is known a shearing machine for edge trimming of panels with an adjustable guide for a vertically guided upper knife rest. In this case, the guide for the upper knife carrier is designed as an intermediate carri...
