Известен способ изготовлени втулок, включающий операции образовани на продольных кромках ленты фасок; резки ее на заготовки, гибки и последующей калибровки путем пропускани установленной па оправке заготовки через р д последовательно расположенных фильер.There is a known method of manufacturing sleeves, which includes the operations of chamfering on the longitudinal edges of the tape; cutting it into workpieces, bending and then calibrating by passing the workpiece set by the mandrel through a series of successive dies.
Недостатком известного способа вл етс невозможность соблюдени необходимых допусков по длине втулок, а также получени плотного стыка (продольного шва).The disadvantage of this method is that it is impossible to observe the necessary tolerances for the length of the sleeves, as well as to obtain a tight joint (longitudinal seam).
С целью повыщени точности и обеспечени плотности стыка по предложенному способу перед гибкой ленту прокатывают с одновременным образованием на продольных кромках фасок, а в процессе калибровки стенку заготовки утон ют на 3-5%, а диаметр уменьшают на 6-7%.In order to increase the accuracy and ensure the density of the joint according to the proposed method, before the flexible tape, the chamfer is formed with the simultaneous formation of chamfers on the longitudinal edges, and during the calibration the wall of the workpiece is thinned by 3-5% and the diameter is reduced by 6-7%.
На фиг. 1 ноказана операци резки на заготовки; на фиг. 2 и 3 - операци прокатки с образованием на продольных кромках фасок; на фиг. 4 - операци предварительной гибки; на фиг. 5, 6 - операци окончательной гибки; на фиг. 7 - операци калибровки.FIG. 1 but shown cutting operations into blanks; in fig. 2 and 3, a rolling operation with the formation of chamfers on the longitudinal edges; in fig. 4 — pre-bending operation; in fig. 5, 6 — final bending operations; in fig. 7 is a calibration operation.

Затем ленту 1 прокатывают между валкамн 2 с повышением точности ее поThe wide roll is divided into ribbons 1 with a tight width tolerance on the disc shears. Then the tape 1 is rolled between roll 2 with an increase in its accuracy by

В совмещенном щтампе 4 осуществл ют предварительную гибку при помощи пуансопа 5 и матрицы 6. После этого обрабатываемую деталь подают на позицию окончательной гибкн с получением втулки, кромки стыка которой как по внутреннему, так и по наружному диаметрам прилегают одна к другой , а фаски наход тс на наружной поверхности . Калибровку по днаметру осуществл ют при нропускапии втулки, размещенной на оправке с зазором, через р д последовательно расположенных фильер 7. При этом происходит утонение стенки втулки на 3-5% и уменьшение ее диаметра на 6-7%, обеспечива плотный стык щва.In the combined chipboard 4, pre-bending is carried out using the punch 5 and the die 6. After that, the workpiece is fed to the final flexible position to obtain a sleeve, the butt edges of which, both in internal and in outer diameters, are adjacent to each other, and the chamfers are on the outer surface. Calibration by one meter is carried out when the sleeve is placed on the mandrel with a gap through a series of successive dies 7. At the same time, the wall of the sleeve is thinning by 3-5% and its diameter is reduced by 6-7%, ensuring a tight joint.
При калибровке избыток материала, образующий волну на наружной поверхности втулки, смещаетс вдоль нее по мере пропускани последней через фильеры, частично заполн в конце операции полость фаски,During calibration, the excess material forming a wave on the outer surface of the sleeve shifts along it as the latter passes through the nozzles, partially filling the chamfer cavity at the end of the operation,

После калибровки втулки подвергаютс химико-термической обработке.After calibration, the bushings are chemically heat treated.
