Description

one

The invention relates to the industry of building materials, in particular, to cantilever knives for the pre-autoclave cutting of arrays of raw cellular concrete.

Izveetey cantilever knife for pre-autoclave cutting of an array of cellular concrete, inclusive cutting element and rezhui1 attachment unit, its element to the rezush frame, its devices. The cutting element of the knife is made with slits in a plane parallel to the lateral wound. However, using such a knife it is impossible to cut high arrays of cellular concrete, as it does not have sufficient rigidity.

The purpose of the invention is to improve the quality of cutting high arrays throughout the cut plane.

To do this, the cutting element of the knife is made in the form of two cutting cheeks installed ia paiciCTOHiHMiH aie less than 20 mm from each other, the front cutting edges of which are located outside the iodine angle from 10 ° to 50 °, and the cutting cheeks are interconnected by cross links, closing the cut section from 0.5 to 5%.

Fig 1 shows a cantilever knife; in fig. 2 - version of spacing of a cantilever knife.

A cantilever nol consists of two cutting n; ek J, transverse links 2 connecting the needles 1, and the holder 3 of the knife. Cheeks / not more than 20 mm apart from each other are oriented in the cutting direction and are interconnected by connections 2, which give Bceii rigidity to the structure and at the same time do not significantly resist the raw weight of the raw mass being cut, between the cheeks of 1 knife, as overlapping cut cross-section from 0.5 to 5%. The cheeks 1 are located at an angle of 10 to 50. The sharpening goal is selected depending on the dynazone gland of the cut array, in order to facilitate a better transmission of the mass of the cut raw.

Prpredvenny on f) 1g. The second embodiment of the cantilever knife allows cutting curved grooves in the arrays in the arrays due to the configuration given to the cheeks / 11.

The proposed device works as follows.

The array to be cut is in a form or on a smooth noddon. When cutting an array in shape, one side of the mold (from the beginning of the cut) is opened, translational movement from the drive is reported to the cantilever knife or form, and the cantilever knife is penetrated into the array to the height of the cut. The cutting of the array is produced up to the OPO-shaped closed bead of the mold (or up to the stop being cut on a smooth pallet). When cutting an array, the outer sides of the cheeks 1 form the cutting surface of a given configuration depending on the embodiment of the cutting cheeks.

The design of the knife allows cutting high arrays of raw cellular concrete in compliance with the specified geometric dimensions of the cut to the entire depth of the arrays.

Subject invention

A cantilever knife for the pre-autoclave cutting of an array of cellular concrete, including a relevant element and a cutting element attachment unit, characterized in that, in order to improve the quality of cutting of high arrays, the cutting element is made in the form of two cutting cheeks installed one from another at a distance of not less than 20 mm and connected to each other by cross links, and in front of iii (from the crotchet cheeks are located outside 1: one mm from 10 ° to 50 °.
