(54) DEVICE FOR CUTTING CHEESE OF CELLULAR

one

The invention relates to the production of building products from cellular concrete by cutting technology and can be used for vertical and longitudinal cutting of raw materials of aerated concrete products .5

Devices are known in which the cutting member is a reciprocating string. In this device, cutting strings are mounted on frames fixed on sliding carriages along guideways. Moving the carriages with the sawn strings, the arrays and are cut vertically or horizontally.

The closest technical solution to the present invention is a device 5 for cutting raw cellular concrete, containing a cutting organ in the form of an infinitely closed contour of cable and string, enveloping the rollers | 2.

The disadvantages of the known device 20 include its limited technological capabilities, which make it possible to carry out only vertical cutting of the massif, and the resulting products have a certain thickness, determined by

CONCRETE

distance between contours. If it is necessary to obtain products (panels) of various sizes, a changeover of the device is required - a change in the distance between the cutting strings.

The purpose of the invention is to expand the technological capabilities of the device by providing both vertical and horizontal cutting of concrete.

The goal is achieved by the fact that in a device for cutting raw cellular concrete containing a cutting organ in the form of an infinitely closed loop of a cable and string, envelopes of rollers and a drive, the infinitely closed loop is provided with an additional cutting string connected to the main cable and located parallel to it, while the infinitely closed contour is made with the possibility of rotation around the longitudinal axis and one of the rollers is driven.

FIG. 1 shows the device in operation (horizontal cutting); in fig. 2 - diagram of the vertical cutting of the array; in fig. 3 is a diagram of making one horizontal cut. The device consists of an infinite closed loop, including cables 1 and two parallel cutting strings 2, the main and additional. Cables 1 go around deflecting rollers 3 roller 4 of shock absorber 5 and drive roller 6. Rollers 3, 4 and 6 are placed on frames 7 equipped with pivot axis 8 in bearings 9. Axes 8 are placed symmetrically to strings 2 that cut the raw 10 array cellular concrete. The device is used as follows. For horizontal cutting of the array 10 on a panel of a certain predetermined thickness H, the endless closed contour is rotated around the axes 8 so that the projection of the distance between the strings on the vertical plane corresponds to the thickness H of the finished panel. After adjusting the panel thickness, the drive roller 6 is turned on, setting the sawing motion with the strings 2. Then served to the cutting strings 2 array 10 raw cell concrete. If it is necessary to change the thickness H of the obtained panel, the contour is turned by the required amount, the maximum thickness of the panel can be obtained, equal to the distance L between the cutting strings 2. The proposed device can provide a vertical transverse cut of the array 10 (Fig. 2). In this case, with the corresponding inclinations or vertical position of the contour, its contour is moved vertically. To accomplish one horizontal cut, the cutting contour is turned to a horizontal position (FIG. 3). The proposed design provides the possibility of infinitely obtainable panels of any thickness of the obtained products from O to L (distance between the strings) with a constant distance between the cutting strings, which greatly simplifies the design and operation of the device, which in turn increases productivity. The invention of the device for cutting raw cellular concrete, containing a rezhuidy organ in the form of an infinitely closed loop of cable and string, enveloping rollers and a drive, characterized in that, in order to expand technological possibilities by providing vertical and horizontal cutting, the infinitely closed loop is provided with an additional cutting tool. a string connected to the main through a cable and parallel to it, while the infinitely closed contour is turned out with the possibility of rotation around the longitudinal axis, and Institute of rollers - drive.
