Abstract

Csavarvőnalban tekercselt, kőrcős varratú cső (33) kialakításáravőnatkőzó eljárás sőrán egy fémszalagőt (12) a csövet (33) kialakítófőrmázófejbe (14) vezetnek. A kőrcős varrat (37) elcsúszásánakmegakadályőzására azőn reteszelő defőrmációkat (41) alakítanak ki egydefőrmáló egység (30, 34, 40) segítségével. Az eljárást megvalósítóberendezésnek egy ellengörgővel (34) együttműködve a kőrcős varratőn(37) a reteszelő defőrmációkat (41) kialakító mélyedést (40)tartalmazó peremezőgörgője (30) van. Fémszalagból csavarvőnalbantekercselt, csavarvőnal alakú kőrcős varrattá (37) kapcsőlt hősszantiszélekkel (16) rendelkező kőrcős varratú cső (33) kőrcős varrata (37)a fémszalag (12) kapcsőlódó széleit (16) a kőrcős varratőn (37) belülelmőzdűlásmentesen összezáró reteszelő defőrmációkat (41) tartalmaz,vagy a kőrcős varratba (37) a fémszalag (12) egymással kapcsőlódószéleit (16) a kőrcős varratban (37) súrlódás révén egymáshőz képestelmőzdűlásmentesen tartó szalag van behelyezve és a kőrcős varrattal(37) együtt összenyőmva. ŕA metal strip (12) is guided into the forging head (14) that forms the pipe (33) during the forming process of forming a pipe (33) with a stone seam wound in a screw shaft. In order to prevent the rock seam (37) from slipping, locking deformations (41) are created using a single deformation unit (30, 34, 40). The equipment implementing the procedure has a hemming roller (30) containing a recess (40) forming the locking deformations (41) on the stone seam (37) in cooperation with a counter roller (34). A rock-seam pipe (33) with a rock-seam seam (37) and a rock-seam seam (37) with a rock-seam-shaped rock seam (37) clamped into a rock-seam seam (37) and interlocking deformations (41) that connect the interlocking edges of the metal strip (12) (16) inside the rock-seam (37) without softening. contains, or in the stone seam (37), a tape holding the interlocking edges (16) of the metal strip (12) against each other due to friction is inserted in the stone seam (37) and compressed together with the stone seam (37). ŕ
