Description

При изготовлении из полосового железа труб с помощью волочени  необходимо конец полосы предварительно загнуть в трубку. Подобна  загибка конца нолосы в трубку обычно производитс  в две операции: предварительна  загибка и окончательна .When making pipes from iron using pipes, it is necessary to bend the end of the strip into the pipe. Similarly, folding the end of the nose into a tube is usually done in two steps: pre-bending and final.

Предлагаемый штамп дает воз.можность производить загибку конца по лосы в трубку за одну операцию, дл  чего пунсон и матрица штампа снабжены кроме обычно примен емой цилиндрической поверхности, также и конической с целью образовани  постепенного перехода от полосы к сгибаемому в трубку концу.The proposed stamp allows the end of the band to be bent into the tube in one operation, for which the punches and the die matrix are provided, in addition to the commonly used cylindrical surface, also conical, in order to form a gradual transition from the strip to the end being bent into the tube.

На чертеже фиг. 1 изображает боковой вид штампа; фиг. 2-вид его сверху; фиг. 3-разрез штампа вдоль оси; фиг. 4-продольный вид полосы с загнутым концом; фиг. 5-вид на полосу с торца.In FIG. 1 is a side view of the stamp; FIG. 2 - its top view; FIG. 3-section of the stamp along the axis; FIG. 4-longitudinal view of the strip with a curved end; FIG. 5-view of the strip from the end.

Штамп дл  загибки концов полосового железа в трубку состоит из пунсона 3 и матрипы 5, снабженных на части своей длины цилиндрической поверхностью 1, переход пдей затемThe stamp for folding the ends of the flat iron into the tube consists of the punch 3 and the matrips 5, provided with a cylindrical surface 1 on a part of their length, the transition then

в коническую поверхность 2. Наиболее изнашивающа с  часть пунсона 3 снабжена с.мепной планкой 4, а матрица 5-упором 6.into the conical surface 2. The most wear-out part of the ram 3 is provided with a gray bar 4, and the matrix with a 5-bar 6.

Работа происходит следующим образо .м. Полоса 7 укладываетс  на ребро в штамп до упора- 6 (фиг. 3) и при ударе пунсона 3 сгибаетс  в цилиндрическую трубку, постепенно переход щую с помощью конуса в полосу. Снабжение пунсона 3 и матрицы 5 коническими поверхност ми 2 позвол ет за один удар пунсона получить вполне загнутый в трубку конец.The work takes place as follows. The strip 7 is laid on the edge in the die as far as the stop 6 (Fig. 3) and upon impact of the puncheson 3 it bends into a cylindrical tube, gradually passing through the cone into the strip. The provision of the punches 3 and the matrix 5 with conical surfaces 2 allows the punches to obtain a completely curved end in one stroke of the puncheson.

Предмет изобретени .The subject matter of the invention.

Штамп дл  загибки концов полосового железа в трубку, состо щий из пунсона и матрицы, отличающийс  тем, что матрица 5 п пунсон 3 снабжены , кроме обычно примен емой цилиндрической поверхности 7, также и конической 2 дл  образовани  постепенного перехода от полосы к сгибаемой в трубку части.A stamp for folding the ends of the banded iron into a tube consisting of a punch and a die, characterized in that the matrix 5 and punches 3 are provided, in addition to the commonly used cylindrical surface 7, also conical 2 to form a gradual transition from the strip to the tube bendable .
