Изобретение относитс  к обработке труб раздачей диаметра. Известен инструмент дл  раздачи труб содержащий установленный на конической оправКе разжимной пуансон, секторы которого выполнены в виде клиньев. Однако стоимость этого инструмента вы сока , а качество внутренней поверхности обрабатываемых труб низкое. Целью изобретени   вл етс  сокращение расходов на изготовление инструмента и nf вышение качества изделий. Поставленна  цель достигаетс  за счет того, .что пуансон выполнен в виде цельного кольца из металла с высокими упругими свойствами. На фиг, 1 показан инструмент, продольгный разрез; на фиг, 2-4 - последовательные положени  инструмента относительно заготовки в процессе обработки, Дл  установки инструмента и трубы в исходное положение в неподвижную опорную втулку 1 вставл ют конец трубы 2 с надетой на его арматурой 3, При атом пуансон 4 ввод т в трубу 2 с зазором. Работа инструмента осуществл етс  в ел дующей последовательности. Привод (на че1 теже не показан), создава  т нущее усилие на шток 5 (см. фиг. 2) и противодействие на торец втулки 6, посредством конусной части штока 5 в пределах упругих деформаций разжимает пуансон 4 и производит локальную раздачу трубы 2, Затем привод осуществл ет раздачу всего участка трубы (см, фиг. 3), прот гива  пуансон 4 вместе со штоком 5 и втулкой 6 и не снима  при этом усилие рааокати . После прот жки пуансона 4 (см, фиг. 4) усилие разжима его снимаетс , и под действием сил упругости восстанавливаютс  его первоначальные размеры . Далее трубу 2 удал ют пуансон 4 со щтоком 5 и втулкой 6 перемещаетс  в исходное положение, и процесс повтор етс . Формула изобретени  Инструмент, дл  раадачн труб, содержаД1ПЙ установленный на конической оправкеThe invention relates to the processing of pipes by distributing the diameter. A known tool for dispensing pipes comprises a crimping punch mounted on a conical mandrel, the sectors of which are made in the form of wedges. However, the cost of this tool is high and the quality of the inner surface of the pipes being processed is low. The aim of the invention is to reduce the cost of tool manufacturing and increase the quality of the products. The goal is achieved due to the fact that the punch is made in the form of a single ring of metal with high elastic properties. Fig, 1 shows a tool, longitudinal section; FIGS. 2-4 show successive positions of the tool with respect to the workpiece during machining; To install the tool and the pipe into its initial position, insert the end of the pipe 2 with the armature 3 attached to the stationary support sleeve 1; with a gap. The tool is operated in the following sequence. The drive (not shown on the plate), creates a tangible force on the rod 5 (see Fig. 2) and the resistance to the end of the sleeve 6, through the tapered part of the rod 5 within the elastic deformations, expands the punch 4 and produces the actuator dispenses the entire pipe section (see Fig. 3), pulling the punch 4 together with the stem 5 and the sleeve 6 and without removing the force of the raokaty. After stretching the punch 4 (see Fig. 4), the unclenching force is removed, and its original dimensions are restored by the action of elastic forces. Next, the pipe 2 is removed with a punch 4 with a brush 5 and the sleeve 6 is moved to its original position, and the process is repeated. The invention of the Instrument, for pipes, containing a tube mounted on a conical mandrel %. « J.WI,, % “J.WI ,, ..- « .«. ,s7.i4-W v-разжимной пуансон, отличающий с   тем, ЧТ5, с целью сниже)и  стоимооти изготовлени  инструмента и повышени  качества издели , пуансон выполнен в виде кольца из металла с высокими упругими свойствами...- ".". , s7.i4-W v-expanding punch, which differs with that of CT5, in order to reduce the cost of manufacturing the tool and improve the quality of the product, the punch is made in the form of a ring of metal with high elastic properties. 4 Ji 65 ш г4 Ji 65 wg // Фш. 3Fsh 3 fPm ЛfPm L
