Description

The invention relates to the processing of metals by pressure, in particular to equipment for the finning of pipes used in chemical and petroleum engineering in the manufacture of air-cooled apparatuses,

A device for winding a tape into a spiral, comprising a spindle with an inner cylindrical surface and a conical working end and a disk bearing cone, is known. The spindle is modeled with the possibility of turning around the axis parallel to the feed axis of the finished product.

It is also known a device for winding a tape into a spiral containing a driving tool mounted in the housing, a shaping flange with working and non-working ends fixed from the rotation and mounted in a cage coaxially with the rotating tool with the possibility of axial displacement from the drive, an elastic element.

A disadvantage of this device is its low reliability due to the constant contact of the surfaces of the rotating tool, the forming flange and the belt during operation, which leads to their wear.

The aim of the invention is to increase reliability by reducing the wear of the rotating tool and the forming flange,

The goal is achieved by the device for winding a tape into a spiral containing a rotating tool mounted in a housing, a holder rigidly fixed on the housing, a shaping flange with working and non-working ends fixed from rotation and installed in the holder along with the rotating tool with the possibility of axial movement from the belt, the elastic element, the device is provided with an annular stop placed inside the cage coaxially with the rotating tool between the housing and the working face of the shape flange, unit for adjusting the displacement of the shaping flange, mounted in the cage with the ability to interact with the non-working end of the latter; designed as a screw

The drawing shows a device for winding the tape into a spiral incision.

The device for winding the tape into a spiral consists of a housing 1, on which on bearings 2 a hollow rotating tool 3 is mounted, driven away from a drive (not shown). In the hole of the spindle 3, a pipe 4 passes through which the tape 5 is wound, and at its end there are gripping protrusions. Coaxially with the rotating tool 3, there is a fixed forming flange 6 with working and non-working ends. The flange b is placed inside the casing 7 rigidly mounted on the housing 1. Inside the casing 7, an annular stop 8 is installed with a rotating tool between the case 1 and the working end of the forming flange 6. Inside the ring stop 8, it can interact with the case 1 and the working end of the forming flange 6 placed the elastic element 9 in the form of a cup spring. At the end of the yoke 7, screws 10 are installed to adjust the axial movement of the forming flange 6, which is carried out from the drive through the pressing mechanism 11,

Navigating to the pipe 4, the tape 5 is fed into the gap S between the rotating tool 3 and the forming flange 6 and is wound into a spiral 12.

Device for winding the tape into a spiral works as follows.

The pipe 4 rotates and moves with a predetermined pitch through a rotation mechanism (not shown) into the winding tool. The rotating tool 3 is driven in rotation from the drive. The forming flange 6 is pressed against the annular stop 8 by a pressing mechanism 11 interacting with the drive. The tape 5 is fed into the gap S. The protrusions located at the end of the rotating tool 3 capture the tape 5 and when the tool 3 is rotated, the tape 5 is wound on the pipe 4 in the form of a spiral 12. Spiral 12 is attached to the pipe, for example by welding. Under the action of the elastic element 9 and the ring stop 8, the forming flange 6 is displaced axially to screws 10, which act as stops, while the gap S is increased by the amount excluding the contact of the belt 5, the rotating tool 3 and the forming flange 6. This value should exceed the thickness of the tape 5 to prevent the loss of stability of the tape 5 and folding during its winding on the pipe 4, due to the fact that the jnepBbie coils of the tape 5 are fixed on the pipe

4, when rotated, the ribbon is wound on the pipe 4 in the form of a spiral 12 with a predetermined pitch. The pipe 4 in this case serves as a mandrel and a means for winding the tape into a spiral.

The proposed device for winding the tape into a spiral provides increased reliability by reducing wear of the rotating tool and the forming flange by placing the latter in a cage containing an annular abutment and an elastic element, and by installing a flange displacement adjustment unit also in the cage with the possibility of interaction with the non-working end of the forming flange.
