The invention relates to pipe production, and more specifically to devices for the task of a liner and mandrel in a continuous mill, and can be used on pipe rolling units, which include a continuous mill with a retained mandrel.

The purpose of the invention is to increase the accuracy of pipes by increasing the rigidity of the device.

without any relative displacement. At the moment when the sleeves are gripped by the first stand rolls, the trolley is disconnected from the hook by interacting the last with an emphasis in the form of a ruler 11. The sleeve continues to move with the rollers at a rolling speed, and the mandrel moves at the speed specified by the rake. After the end of rolling, the mandrel is retracted to its initial position and along the course, the hook is rotated and the cart is connected to the mechanism of axial movement of the mandrel. In view of this, it is designed for a sleeve and a lock for a mandrel for

The device comprises a successively one initial full mounted on the base 1 mechanism of the axial movement of the mandrel, having a lock 2 under the mandrel with the roller support 3, carrying its rod 4, connected to it by the rail 5, interacting with the drive gears in the housing 6 and a hook 7 placed on the lock, a movable support of the sleeve in the form of a trolley 8 with rollers 9 and a groove 10, connected by a hook to the axial movement mechanism of the mandrel, and a stationary stop fixedly in the path of the trolley, for example, in the form of a ruler 11, about baking grip and disengagement by turning the hook.

The device works as follows.

A sleeve with a mandrel assembled off the mill axis is transferred to the mill line and placed so that the sleeve fits into the groove 10, the shank of the mandrel is oriented into lock 2, and the other end is supported by a fixed support in front of the mill. Then, the gear drive is turned on and the rail 5 moves the rod A with the lock carrying the bearing. Thanks to the hook 7 of the castle and the trolley 8, on which the gil

without displacement and without deflection. I

The proposed device has

reliability in operation and ensures the transportation of the liner with the mandrel along the mill axis, helping to obtain 25 precise rolled tubes.

Invention Formula thirty 35 40 The driver of the pipe-boring mandrel mill, containing a drive mechanism for axial movement of the mandrel, having a lock under the mandrel, and a sequentially located movable support of the liner connected to the axial movement mechanism of the mandrel, characterized in that, in order to improve the accuracy of the pipes by increasing the rigidity of the device, roller support of the lock, while the mechanism of axial movement of the mandrel and the movable support of the sleeve, which is wave in the form of a trolley, is connected through a hook located on the lock, and permanently installed on the path of the progress of the truck, the task of the sleeve on the frame by the profile emphasis of the turn of the hook occurs. o without any relative displacement. At the moment the sleeves are gripped by the rollers of the first stand, the trolley is disconnected from the hook by interacting, the latter with an emphasis in the form of a ruler 11. The sleeve continues to move with the rollers at a rolling speed and the mandrel at a speed specified by the rail. After the end of rolling, the mandrel is retracted to the starting position and the hook is rotated and the cart is connected to the mechanism of axial movement of the mandrel. In view of this, it is constantly under the liner and the lock for the mandrel that one initial polo living Because of the rigid support when moving the rollers on the bed transport the sleeve with mandrel to the mill without displacement and without deflection.
