Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for rolling a long columnar body (hereinafter simply referred to as a tube and rod) in the shape of a tube, rod, or rope using an inclined roll rolling mill, and then rolling it up. .

An inclined roll rolling mill is, for example, a perforator, elongator or reeler used in seamless steel pipe production, or a planetary cross mill used in steel bar production, in which the rotating axis of a set of rolls is inclined with respect to the direction in which the material travels, and the material is rolled between the set of rolls. This is a general term for rolling mills that apply plastic pressure by clamping the material and moving the material forward while rotating due to the rotation of the rolls. In such an inclined roll rolling mill, when the rolls are fixed, the material to be rolled moves forward while rotating like a screw. Since the rolled material is twisted or jumped out of the pass, this rolling method has been limited to rolling short, thick products. In order to solve these problems of the inclined roll rolling method, a so-called planetary cross mill has been proposed in which the roll set is not fixed and revolves around the material to be rolled, but this method also It is extremely difficult to eliminate the rotation of the rolled material, and the number of revolutions of the rolled material usually changes as rolling progresses. If a tube rod rolled by such an inclined roll rolling mill is wound up by a conventional wire winder, the tube rod will become severely twisted, making it difficult to process in the next process, and reducing the product value. I couldn't help it.

The present invention is capable of winding a tube rod without twisting the tube rod, or with a predetermined twist, by a tube winder disposed close to an inclined roll rolling machine that rolls the tube rod. The purpose is to provide equipment.

The main part of the present invention is, as shown in FIGS. 1 and 2, a bevel gear 2 driven by a drive shaft 1.
The pipe is made up of It has a structure for winding a rod, and is further comprised of a bevel gear 8 driven by a drive shaft 7, a bevel gear 9 meshing with and driven by the bevel gear 8, and a rotating frame 10 fixed on the bevel gear. It has a structure that gives rotational motion to the take-up drum 5.

To explain a method of winding a tube rod 12 that has been guided by a tube rod guide tube 11 without twisting the tube rod that is rotating and moving forward from an inclined roll rolling mill using the device of the present invention, the method is as follows. The leading end of the front end is caught in the gap between the winding drums 5. By driving the drive shaft 1 as described above, driving force is sequentially transmitted to the winding drum 5, and the winding drum 5 is rotated around its rotating shaft 13 to wind up the tube rod. . The winding speed at this time is equal to the forward speed of the tube and rod at the exit side of the rolling mill. Further, by driving the drive shaft 7 as described above, the rotation is transmitted to the bevel gear 9, and the winding drum 5 is rotated about its pivot axis 14 integrally with the rotation of the bevel gear. The number of revolutions of the winding drum 5 at this time is equal to the number of revolutions of the tube rod on the exit side of the rolling mill.

When winding a tube rod with a predetermined twist using the apparatus of the present invention, the number of revolutions of the winding drum 5 may be made to differ by a predetermined ratio from the number of revolutions of the tube rod at the exit side of the rolling mill. good.

The rotating part of the device of the present invention can be designed to be significantly smaller in weight and rotation radius than the rotating part of a planetary cross mill, and can wind up a tube rod without twisting or with a predetermined twist. .
