Изобретение относитс  к технологий обработки древесины методами пластической деформации.The invention relates to the technology of wood processing methods of plastic deformation.

Известен способ получени  из древесины кольцеобразной шаровой поверхности, исропьзуемой в древесно-металлических издедн х типа радиально-упорных подшипников, заключающийс  в том, что из древесины нарезают заготовки, нанос т на их стыкуемые поверхности клей, прессуют с последующей запрессовкой в погеэсть, имеющую шаровую поверхность, и термообработкой до момента полимеризации кле  и стабилизации требуеtftou формы и размеров.A known method for producing from the wood an annular spherical surface, used in wood-metal parts such as angular contact bearings, which consists in cutting pieces from wood, applying glue to their joined surfaces, pressing, followed by pressing into a surface that has a spherical surface. , and heat treatment until the polymer cures and stabilizes the shape and size required.

Недостатком существующего способа  вл етс  то, что шарова  поверхность вследртвие неравномерного прессовани  приобретает неоднородность физико-механических свойств по высоте, нестабильна по форме и размерам и имеет невысокие физико-механические показатели.The disadvantage of the existing method is that, due to uneven pressing, the ball surface acquires a heterogeneity of physical and mechanical properties in height, is unstable in shape and size, and has low physical and mechanical properties.

Целью изобретени   вл етс  повышение физико-механических шаровой по;Верхности и сокращение производственного цикла.The aim of the invention is to increase the physicomechanical ball on the surface and reduce the production cycle.

Эта цель достигаетс  тем, что использу-. ют древесину одноосного прессовани  с влажностью ве выше 15%, заготовки нарезают в ввде торцовых пластин трапециевидной формы, устанавливают из многогранной усеченной пирамидой в ограничительный коитур , в котором производ т прессование до получени  усеченного конуса. This goal is achieved by using-. Uniaxial pressing wood with a moisture content above 15% is used, the blanks are cut into a trapezoid-shaped end plate, set from a multi-faceted truncated pyramid into a restrictive coitur, which is pressed before a truncated cone is obtained.

На чертеже изображено предложенное устройдтво в разрезе н разрез по А-А.The drawing shows the proposed device in the section n section along the AA.

Осуществление способа получени  кольцеобразной шаровой сферы из 0 ревесннь( щюизводитс  по следукмдей тезоюлогин.The implementation of the method of obtaining a ring-shaped spherical sphere from 0 is external (it is produced according to the following tezojugin.

Из древесины одноосного прессовани  нарезаютс  исходные заготовки 1 в форме трапециевидных торцовых плиток, которые устанавливаютс  многогранной усеченной пирамидой в ограничительный контур 2, с последующим прессованием до получени  усеченного конуса, запрессовкой его в полость шаровой сферы и термообработкой прн услови х, необходимых дл  полимеризации кле  и стабилизации формы в размеров шаровой поверхности.From the uniaxial pressing wood, the original blanks 1 are cut into the shape of trapezoidal end plates, which are installed with a multifaceted truncated pyramid into the restrictive contour 2, followed by pressing to obtain a truncated cone, pressing it into a ball sphere and heat treating the conditions necessary for polymerization of glue and stabilization Forms in sizes of a spherical surface.
