SU876444A1 - Device for cutting heat-insulating and acoustical building material - Google Patents

Description

The invention relates to the industry of heat-insulating and acoustic building materials, in particular to devices for cutting silicate porous materials, mineral wool slabs on a synthetic binder, etc.

A device for cutting 'cellular concrete' is known, comprising a frame on which a knife with an oscillating mechanism is mounted

However, when cutting materials with such a device, there are large losses of cut material, in addition, the installation itself is cumbersome.

A device for cutting cellular concrete products is also known, containing a base, a frame, a drum with an oscillating motion drive, cutting strings and guide rollers ^ 2].

The disadvantages of the known device are the complexity of the design, the large inertia of the moving parts, the frequency of cutting, the possibility of cutting only to autoclaved concrete and only certain dimensions.

The purpose of the invention is to simplify the design.

This goal is achieved by the fact that the device for cutting heat-insulating and acoustic building materials containing a frame, spring-loaded cutting strings and a drive of tunes. to the rocker arms, and others, are spring-loaded relative to the frame.,

The drawing shows a schematic diagram of a device.

The device consists of a frame 1, on which, through the hinges 2, the rocker arms 3 and the drive 4 of the oscillatory movement are installed. Cutting jets 876444 5 are attached to one end of the rocker arm 3, the other ends of which are attached to the frame 1 through the spring 6,

The device operates as follows.

The vibrational drive 4 communicates through the rocker arms 3 vibrational movements to the cutting strings 5 with an oscillation frequency of 0.2-1 kHz, which return the springs 6. The cutting array 7 is fed perpendicular to the cutting strings. The number of cutting strings and:. The distance between them is regulated depending on the dimensions of the array and the desired thickness of the products.

The use in the manufacture of the invention will simplify the design of plants for cutting building materials, as well as reduce the cost of production of building materials by reducing the loss of cut material.

3 to 5, the other ends of which through the springs 6 are attached to frame 1, the device operates as follows. The oscillating drive drive 4 communicates through the rocker arms 3 oscillatory movements to the cutting strings 5 with a frequency of 0.2-1 kHz, which return the springs 6 to the initial position. The array 7 to be cut is delivered to the perpendicular to the cutting strings. The number of cutting strings and the distance between them is regulated depending on the dimensions of the mass and the desired thickness of the products. The use in the production of the invention will simplify the design of installations for cutting construction materials, as well as reduce the cost of production of construction materials by reducing the loss of the material being cut. 4 The invention The device for cutting of heat insulating and acoustic building materials, comprising a frame, spring-loaded cutting strings and an oscillating motion drive, characterized in that, for the purpose of simplifying the construction, the apparatus is provided with rocker arms hingedly mounted on the frame and interacting with the vibratory motion drive , and the cutting strings at one end are fastened to the yokes, while the others are spring-loaded relative to the frame.
