US 6,318,660 B1 · Coiling machine for rolled stock

Abstract

Coiling machine for rolled stock located downstream of a rolling train, including a mandrel mounted rotatably around an axis or rotation on a stationary structure, the mandrel being mounted cantilevered on the stationary structure and including an inner wall orthogonal to the axis or rotation and an outer end with which a cylindrical plate is suitable to selectively cooperate, the cylindrical plate being movable from a working position, where it is arranged substantially orthorgonal to the axis of rotation so as to define a side wall parallel to the inner wall, to allow the coil of rolled stock to form and an inactive position wherein it is distanced and lowered with respect to the mandrel so as to allow the coil of rolled stock to be axially removed.

Dependent claims

A coiling machine for rolled stock located downstream of a rolling train (11), comprising;

(i) a stationary structure (23);
(ii) a mandrel (20) cantilever mounted on the stationary structure (23) and rotatable around an axis of rotation (21), the mandrel comprising a cylindrical surface having an outer end, and a first lateral wall (24) orthogonal to the axis of rotation (21);
and
a containing plate (29) pivotally mounted on the stationary structure (23) for being movable between a working position, wherein the containing plate (29) is arranged substantially orthogonal to the axis of rotation so as to define a second lateral wall parallel to the first lateral (24) wall, to allow the coil of rolled stock (12) to be formed, and an inactive position, wherein the containing plate (29) is lowered with respect to the mandrel so as to allow the coil of rolled stock (12) to be axially removed from the outer end of the cylindrical surface of the mandrel (20).

A coiling machine for rolled stock located downstream of a rolling train, comprising:

a stationary structure;
a mandrel mounted rotary around an axis of rotation on the stationary structure, wherein the mandrel is mounted cantilevered on the stationary structure and comprises an inner wall orthogonal to the axis of rotation and an outer end, and
a cylindrical plate suitable to selectively cooperate with the outer end, the cylindrical plate pivotably movable between a working position, wherein the plate is arranged substantially orthogonal to the axis of rotation so as to define a side wall parallel to the inner wall, to allow the coil of rolled stock to form, and an inactive position, wherein the plate is distanced and lowered with respect to the mandrel so as to allow the coil of rolled stock to be axially removed,
wherein a device is provided to facilitate the formation of the first spirals of the coil of rolled stock on the mandrel,
the device comprising a first guide and a second guide substantially semi-cylindrical in shape, each guide having an inner cavity, and arranged such that the first guide is above the mandrel and the second guide is below the mandrel, each of the guides having an inner profile mating with the outer cylindrical surface of the mandrel.
