Abstract

1. Устройство для разрезания покрышек по одной или одновременно по нескольким линиям реза, включающее металлический цилиндр с выемками и расположенные соответственно выемкам заточенные дисковые металлические лезвия с толщинами, большими ширин выемок в цилиндре, отличающееся тем, что лезвия установлены на поворотном валу с эксцентриситетом «a» относительно оси вала, причем при рабочем положении поворотного вала лезвия плотно касаются своими боковыми гранями боковых стенок соответствующих выемок. ! 2. Устройство по п.1, отличающееся тем, что при положении поворотного вала, соответствующем моменту надевания покрышки на металлический цилиндр с выемками, режущие кромки лезвий образуют с наружной поверхностью цилиндра зазор шириной Z, выбираемой с учетом соотношений ! Z≥H и , ! где Z - ширина зазора между наружной поверхностью цилиндра и режущими кромками лезвий; Н - наибольшая толщина разрезаемого материала; а - величина эксцентриситета; в - ширина выемки; β - угол между образующими конических поверхностей лезвия.1. A device for cutting tires along one or simultaneously along several cutting lines, comprising a metal cylinder with recesses and sharpened disk metal blades located respectively in the recesses with thicknesses greater than the width of the recesses in the cylinder, characterized in that the blades are mounted on a rotary shaft with an eccentricity "a "Relative to the axis of the shaft, moreover, with the working position of the rotary shaft, the blades tightly touch their side faces of the side walls of the corresponding recesses. ! 2. The device according to claim 1, characterized in that when the position of the rotary shaft corresponding to the moment of putting on the tire on the metal cylinder with recesses, the cutting edges of the blades form a gap Z of width selected from the outside with respect to the ratios! Z≥H and,! where Z is the width of the gap between the outer surface of the cylinder and the cutting edges of the blades; H is the largest thickness of the material being cut; a is the eccentricity value; in - the width of the recess; β is the angle between the generators of the conical surfaces of the blade.

Claims

1. A device for cutting tires along one or simultaneously along several cutting lines, comprising a metal cylinder with recesses and sharpened disk metal blades located respectively in the recesses with thicknesses greater than the width of the recesses in the cylinder, characterized in that the blades are mounted on a rotary shaft with an eccentricity "a "Relative to the axis of the shaft, moreover, with the working position of the rotary shaft, the blades tightly touch their side faces of the side walls of the corresponding recesses.

2. The device according to claim 1, characterized in that when the position of the rotary shaft corresponding to the moment of putting on the tire on the metal cylinder with recesses, the cutting edges of the blades form a gap Z with a outer surface of the cylinder, taking into account the relations

Z≥H and

,

where Z is the width of the gap between the outer surface of the cylinder and the cutting edges of the blades; H is the largest thickness of the material being cut; a is the eccentricity value; in - the width of the recess; β is the angle between the generators of the conical surfaces of the blade.
