Description

Дл  изготовлени  крутонзогнутых трубных угольников обычно прамен ют состо щие из пуансона с матрицей двуручьевые штампы, один из ручьев которых гибочный, а другой - обжимной калибровочный, причем-процесс изготовлени  ведут с применением оправок или сердечников, вводимых в полость трубной заготовки с тонкими стенками, чтобы придать угольнику необходимую форму по сечению.For the manufacture of steeply bent tube squares, two-strand dies consisting of a punch with a matrix are usually used, one of the streams is bending and the other is crimping, and the manufacturing process is carried out using mandrels or cores inserted into the cavity of the tube billet with give the square the desired shape over the cross section.

Применение оправок-сердечников усложн ет процесс и делает его трудоемким.The use of mandrel cores complicates the process and makes it time consuming.

Отличительной особенностью предла1аемого двуручьевого штампа  вл етс  выполнение гибочного ручь  закрытым в поперечном сечении -с глубиной ручь  матрицы, большей диа.метра заготовки, а обжимной калибровочный ручей выполн ют с разъемом между пуансоном и матр:;цей , проход ш.им в продольном сечении по двум дугам одной и той же длины, со средним радиусом, равным среднему радиусу изготавливаемого угольника.A distinctive feature of the proposed two-strand die is that the bending brook is closed in cross section — with the depth of the die, greater than the diameter of the workpiece, and the crimping calibrating broach is made with a connector between the punch and the mat:; two arcs of the same length, with an average radius equal to the average radius of the square to be made.

Такое выполнение двуручьевых штампов позволило осуществл ть изготовление крутоизогнутых трубных угольников из заготовок с тонкими стенками без применени  оправок.Such an embodiment of two-strand dies made it possible to manufacture steep-curved tube squares from blanks with thin walls without the use of mandrels.

На фиг. 1 показан в двух проекци х двуручьевой. штамп перед началом деформации заготовки; на фиг. 2- этот же штамп в со.мкнутом состо нии.FIG. 1 is shown in two projections with two arms. stamp before the deformation of the workpiece; in fig. 2- the same stamp in the closed state.

Гибочна  часть штампа состоит из пуансона 1 и матрицы 2, также и обжимна  или калибровочна  часть штампа состоит из пуансона 5 и матрицы 4.The bending part of the stamp consists of the punch 1 and the die 2, and also the crimping or calibration part of the stamp consists of the punch 5 and die 4.
