Description

В производстве резиновых изделий часто требуютс  заготовки г определенным распределением массы по их длине, В частности, это не обходимо при штамповании галош, где масса заготовки измен етс  в направлении от носка к заднику.In the production of rubber products, billets are often required by a certain mass distribution along their length. In particular, this is not necessary when stamping galoshes, where the mass of the billet varies from toe-to-back.

В насто щее врем  заготовку дл  галош получают из обрезка кру лого шнура резиновой смеси С последующим загибанием по кра м вручную.Presently, a galos blanks are made from trimming a rubber cord, followed by hand-bending along the edges.

По этому процессу, помимо большой его трудоемкости. ; аготовки получаютс  нестандартными, и наложение заготовок на сердечник неточное .In this process, in addition to its great complexity. ; Preparations are non-standard and the imposition of blanks on the core is inaccurate.

В результате имеетс  большое количество брака при производстве |птампованных галощ.As a result, there is a large amount of rejects in the production of | ptamped galoshes.

Предлагаемое устройство дл  формовани  резиновых заготовок отличаетс  тем, что оно состоит из подвижного барабана, поверхность которого выточена в соответствии с желаемым профилем заготовки, и охватывающего его неподвижного полукольца, внутренн   поверхность которого также выточена в соответствии с желаемым профилем заготовки .The proposed device for forming rubber blanks is characterized in that it consists of a movable drum, the surface of which is machined in accordance with the desired profile of the blank, and a fixed semi-ring enclosing it, the inner surface of which is also machined in accordance with the desired profile of the blank.

Предлагаемое устройство позволит получить заготовки с жeлaeмыi l распределением массы по длине, а также осуществить непрерывность процесса формовани  резиновых заготовок и совместить его с транспортировкой изделий.The proposed device will allow to obtain blanks with the desired distribution of mass along the length, as well as to carry out the continuity of the process of molding rubber blanks and to combine it with the transportation of products.

На чертеже изображено предлагаемое устройство, работу которого осуществл ют следующим образом.The drawing shows the proposed device, the operation of which is carried out as follows.

Шнур круглого сечени  /, получаемый из шприцмашины 2, разрезаетс  дозатором 5 на части заданной длины. Отрезанные части шнура 4 подаютс  в зазор, образованный наружной поверхностью вращающегос  барабана 5 и внутренней поверхностью, образованной неподвижным полукольцом 6.The round cord / obtained from the syringe 2 is cut by the dispenser 5 into pieces of a predetermined length. The cut parts of the cord 4 are fed into the gap formed by the outer surface of the rotating drum 5 and the inner surface formed by the fixed semi-ring 6.

Эти поверхности образовань вращением симметричных плоских кривых относительно эксцентрично смещенных центров 0| и Oz барабана и полукольца. Смещением центров достигают п.аавное уменьшение зазора между поверхност ми.These surfaces are formed by the rotation of symmetric flat curves with respect to eccentric displaced centers 0 | and Oz drum and half rings. By the displacement of the centers, the gap between the surfaces is reached.
