Abstract

Usage: in the line of the pipe mill rolling mill pipe pipe The essence of the convolutional machine will comprise a container 1 with a cylindrical receiver 2 for a bay and a guide wire 3, a drive 4 rotations of the uniter, bending 5 and 6 rollers The axis of rotation of the container is aligned with the transverse axis of the cylindrical receiver 2 as a result, the radius of the circle circumscribed around the external dimensions of the container with the receiver is reduced almost only by half. This will reduce the moment necessary for the rotation of the container, and therefore, ergozatraty coagulation pipe 1 during rolling yl,

11, the invention relates to the field of metal forming, and more precisely, can be used to roll pipe E in the line of a hunger mill for pilger type pipes

A well-known state-of-the-art machine is used in which bending ropes and a receiving container are installed permanently

The disadvantage of this design is that when using it to curl pipe into the coils exiting the mill, to prevent damage to the surface of the pipe, the vertical machine should be installed at a considerable distance from the mill, which significantly increases the area occupied by the milling machine

Known are convolutional machines: the closest machine to the genesis is the convolutional machine used to implement the method of rolling rolling and pipes. This convolutional machine is for rolling pipes into a bag in the mill line. contains a container for receiving the boot, mounted on the spindle coaxially with the pipe leading out of the mill. The container is rotated relative to the axis tangent to the coil placed in the container and is connected with the pipe leading out of the mill

The drawback and design of the convolutional machine is that the center of gravity of the container and the bay do not coincide with the center of rotation. As a result of this, when the container rotates, there is a moment that prevents rotation, equal to the mass of the container and the receiver for the pipe riot at a distance from the center of gravity to the center of rotation

Another disadvantage of the known design of the convolutional machine is that its cross-sectional dimensions are more than two times the diameter of the pipe winded with its help

The aim of the invention is to reduce energy consumption.

The drawing shows a butcher-on machine dp mill "olodnoy pipe rolling longitudinal section

The reamer for a tube rolling mill includes a container 1 with a cylindrical receiver 2 dp riots and a guide wire 3, a drive 4 for rotating the container 1 around the axis aa of the current part of the wire bending 5 and 6 push rollers mounted in the container 1 for you “One piece of wiring.

Lead a 3 is made in the form of a pipe with an axis in the form of a curve with the exit axis

its parts are placed tangentially to the circumference of the cylindrical surface of the receiver 2. At the same time, the cylindrical receiver 2 is placed with its transverse alignment

axis with the axis of rotation of the container 1

A rotation drive 4 is coupled to the container via a gear train and spindle 7, rigidly fixed to the container 1 and mounted on a bearing; supports 8

The engaging gears 9 and 10 are fixed respectively to the spindle 7 and the shaft 4 of the container rotation drive 4

The machine operates as follows

5 The rebellion machine is installed in the mill line in such a way that the lead part of the guide 3 is aligned with the axis of the pipe leading out of the mill Gear 10 is rotated by motor 4 and is in constant engagement with gear gear mounted on spindle 7 in rotation, the latter, and therefore the guide wiring and the container

5 The pipe exiting the mill receives impulse rotation and moves in the longitudinal direction, then it enters the input part of the wiring 3 and through it into the rollers 5 and 6. Under the influence of the 0 "chimney roller b, the pipe bends to a curvature corresponding to the diameter of the cylindrical receiver 2 for coarse and with the help of rollers 5 it is pulled into the receiver for laying the pipe formed into a spiral 5

Due to the fact that the outlet pipe from the mill rotates in a pulse fashion, the spindle 7 and the container 1 rotate continuously at a speed equal to the average rotation speed

0 pipes in the mill

Due to the center of gravity of the container with the cylindrical receiver on its axis of rotation when the axis of rotation of the container is aligned with the transverse

5 with the axis of the cylindrical receiver, to rotate the container, only friction sipes must be overcome in the bearing support. 8

Such a constructive design of the shrink-wrapping machine will reduce the moment required for rotation of the container due to a decrease in the weight of the machine by placing the center of the container’s weight on the smallpox of its rotation provided that the axis of rotation of the container is aligned with the transverse axis of the cylindrical receiver.
