SU701824A1 - Machine for cutting out sheets from blocks of polymeric materials - Google Patents

Description

The invention relates to the field of devices for the mechanical processing of polymeric materials. Devices for cutting formation formations are known, comprising a frame and a cutting tool in the form of a series of electrically heated nufom wires fll. These devices have low productivity, since the blocks are fed to the cutting tool only by the force of the block. Also known are machines for directing sheets of foam plastic blocks containing a frame on which a lifting table with reciprocating shifting is installed in the guides, as well as a vertical movement of the Fsji machine. The disadvantage of such a machine closest to that proposed In technical essence and in terms of breaking effect, low productivity is achieved (after a cut, it is necessary to increase the height of the site and set the required thickness of the cut sheet to the nonius but). The purpose of the present invention is to increase the productivity of the stash by providing for an automatic lowering of the stitch after each cut. The goal is achieved by the fact that the machine is equipped with a track switch for driving vertical movement of the pin and interacting with it in the idle section of the table with a cam rigidly attached to the table. At the same time, the changeover of the machine to a different thickness cuts the sheets of a cam made as a group of parallel-installed elements of different lengths, and the traveling switch is installed with the possibility of re-rolling in the direction of the eleventhflank perpendicular to the length direction.
