Abstract

The invention relates to the building materials industry and can be used in the manufacture of concrete products by cutting technology. The purpose of the invention is to improve the quality of the cut. The device comprises a frame 1, a cutting member 4 and a drive mechanism in the form of crankshafts 2 placed parallel to the frame 1. frame 1 on both sides of platform 7 for feeding array 19, raw cellular concrete and followers rollers 15 mounted on one of the arms of rocker arms 5. When platform 7 with array is fed to cutting body 4, its string makes a circular motion At the same time, the end of the rocker arm 5 with the following roller 15 moves along the protrusions 14 of the copier 13 and additionally causes the string to oscillate. 2 Il.

ly 2 are placed on frame 1 on either side of platform 7. The actuator 3 moves the cutting member 4 consists of a pair of bevel gears 8, some gears of which are fixed on the knee-25 shafts 2, and others on the drive shaft 9 having a pulley 10. The fastening elements of the cutting body 4 contain a tension spring 11 and a tension element 12, which compensate for inaccuracies in the manufacture of cutting strings and uneven cutting forces. In addition to the rocker arms 5 pivotally mounted on crankshafts 2, the mechanism 6 for additional movement of the cutting member 4 comprises two copiers 13 with protrusions 14 placed on the base 1 on both sides of the platform 7, and followers rollers 15 mounted by axes 16 on the other arms rocker arms 5. The self-propelled platform 7 moves along the rails 17 and is intended to accommodate the pallet 18 with the array 19 raw cellular concrete being cut.

The device works as follows

In the initial position, the cutting strings are tightened with the help of tensioning elements 12, which ensures guaranteed contacting of the follower rollers 15 with copiers 13. A parallelogram system consisting of two rocker arms 5 and 40 is formed.

The 13 strings of the cutting member 4 receive additional reciprocating movements superimposed on the crank curve, which positively affect the quality of the surface in the cutting plane. At the end of the cutting process of the array 19, the pickup device pallet 18 is removed from the platform 7, which is returned to its original position. Further, the cutting cycle is repeated in the same sequence.
