Изобретение относитс к обработке стекл нных заготовок и может быт использовано при закреплении их на оправках при шлифовании.The invention relates to the processing of glass blanks and can be used for fixing them on mandrels during grinding.
Известен способ закреплени цилидрической стекл нной заготовки на оравке , при котором заготовку устанавливают на оправку с зазором и заполн ют его .термопластичным клеевым составом с последующим охлаждением 1 .A known method of fixing a cylindrical glass preform on an arm, in which the preform is mounted on a mandrel with a gap and filled with a thermoplastic adhesive composition, followed by cooling 1.
Однако при таком исполнении aje обеспечиваетс надежное закрепление загртовки. .However, with this design aje provides a secure fastening of the loading. .
Цель изобретени - повышение надежности закреплени .The purpose of the invention is to increase the reliability of fastening.
Поставленна цель достигаетс тем, что оправку предварительно нагревают , а охлаждение выполн ют в верти альном положении заготовки, обеспечивеиощем соосность поверхностей заготовки иоправки.The goal is achieved by the fact that the mandrel is preheated, and the cooling is performed in the vertical position of the workpiece, ensuring the alignment of the workpiece surfaces and the correction.
На фиг. 1 схематически представл способ закреплени заготовки на фигГ2 - участок контактировани оправки и заготовки в момент остывани .FIG. 1 is a schematic representation of a method for securing the preform in FIG. 2 — a portion of contact between the mandrel and the preform at the time of cooling.

Термопластичный клеевой состав 2 наноситс на оправку 1 с избытком. Излишки кле при введении оправки 1 во внутреннюю полость заготовки 3 подрезаютс нижним торцом заготовкиThe thermoplastic adhesive composition 2 is applied to the mandrel 1 in excess.

When the mandrel 1 is cooled, its diameter decreases, which causes stretching of the adhesive layer. The glue, in turn, is not towards the center of the mandrel 1, the workpiece 3, which as a result

Thus, during subsequent processing the body of the workpiece. 3 is in a stressful state, which ensures an increase in the reliability of fixing during subsequent processing.
Положительный эффект предлагаемого изобретени состоит в повышении выхода годных заготовок 3.The positive effect of the present invention is to increase the yield of workpieces 3.
