Machine holding-down clamp

Abstract

Pressure device (4) of a machine for processing blanks (11) made of soft material, preferably a foam contour cutting machine, with a height-adjustable presser parallel to the receiving table (2) Pressure plates (6 to 10), wherein the cutting machine has at least one intermediate bracket (13) for clamping a cutting knife (12) adapted to the width of the blank (11) on two cross beams of the machine base (1) , should continue to be improved in such a way that, despite the ideal large bearing surface, a corresponding lateral displacement of the intermediate bracket ensures a rapid and automatic replacement of the blank. For this purpose, it is proposed that the hold-down device (4) has a height-adjustable support member supported on a crossbeam, which supports the hold-down device frame (5), and the hold-down pressure plates (6 to 10) can be mounted longitudinally on the hold-down device frame (5). 5), and in order to be able to accommodate the intermediate bracket (13) between the compression pressure plates, the compression pressure plates (6 to 10) have a gap (14) that exceeds the width of the middle bracket (13) at least in the area of ​​the middle bracket (13) shape distance (Figure 1).

Description

technical field [0001] The invention relates to a hold-down device of a machine for processing blanks made of soft material, preferably a foam profile cutter, with a height-adjustable press parallel to the receiving table. Pressing the plate, wherein the cutting machine has at least one intermediate support of the cutting tool that is clamped on the two beams of the machine base and can be adapted to adjust the width of the blank. Furthermore, the invention relates to a method for operating a pressing device. Background technique [0002] In the foam material cutting machine, the horizontal, vertical or to some extent arbitrary orientation cutting tool cuts into the foam material and generates a displacement force acting on the workpiece to be cut during the cutting process. In addition, due to the friction between the tool and the foam material, forces are formed in the direction of the pivoting movement or in the longitudinal direction of the cutting groove, and due to th...
