Abstract: Winding machine for rolled or drawn wire/rod with turn clutch device for automatic winding of the type comprising a reel with a mandrel and base flange and an external mobile containment counter flange, wherein the counter flange is openable to allow the axial extraction from the mandrel of the reel of the completed coil, the flange of base comprising a recess to receive the head of the wire/rod to be wound, with an overturned trapezoidal annular recess with corresponding reduction towards the base for auto-clamping the wire/rod to start winding without requiring pincers.
Abstract: Device for receiving and discharging bars fed forward in a longitudinal direction, preferably from a rolling mill and after being cut to length, of the type with two pair of adjacent, counter-rotating rollers/drums, characterized by the fact that the said bars are sent alternately into a zone immediately above each pair of said drums, which rotate and drag the bar between them in a downwards direction, and which subject the bar to elastic, friction compression in order to slow it down while it is being fed forward and then, continuing their rotation, make the bar fall in a pick-up zone below.
Abstract: Disclosed is a method for receiving and discharging bars. Adjacent parallel rotating drums receive bars in longitudinal advancement and discharge them by dropping them onto an underlying cooling bed in a rolling mill plant. Each drum is provided with four opposite channels rotating in unison. At first two bars are fed in logic succession into two adjacent channels of a drum and, then at least two bars are fed in logic succession into at least two adjacent channels of the adjacent drum, and while a drum receives its two bars, the other one rotates for discharging its received bars. The discharging occurs in two progressive steps. First, rotation of the drum through a certain angle for allowing the discharge of a first bar and then, further rotation of the drum to allow the discharge of the second bar.
Abstract: A rolling stand having a stand casing, a first cylinder holding packing having a rolling cylinder rotatably mounted therein, a second cylinder holding packing having a rolling cylinder rotatably mounted therein with a rolling axis in parallel relation to the rolling axis of the rolling cylinder of the first cylinder holding packing, and four tie rods positioned at respective comers of the stand casing and each having a right-hand screw and a left-hand screw threadedly connected respectively to the cylinder holding packings so as to move at least one of the packings relative to the other. One of the cylinder holding packings includes an external bridge part coupled to the tie rods at either the right-hand screw or the left-hand screw, an internal part directly receiving the cylinder therein and coupled to the tie rods along an unthreaded portion of each of the tie rods, and a fluid dynamic cylinder connected to the external bridge part and to the internal part.
Abstract: A process for a packing system for rolling-mill stock in which the packing system includes a continuous conveyor, an overhead transfer with a suspended electromagnet, and a lifter positioned below the conveyor in association with the overhead transfer. The process includes the steps of stopping an advancement of a first rolling-mill stock below an electromagnet collector an a multilayered rolling-mill stock below the overhead transfer, raising the first rolling-mill stock by the collector from the conveyor, lifting the multilayered rolling-mill stock toward the electromagnet, advancing a second rolling-mill stock while the overhead transfer deposits the multi-layer rolling mill stock into a packing pocket, stopping the advancement of the second rolling-mill stock below the collector, and depositing the first rolling-mill stock onto the second rolling-mill stock while the overhead transfer returns to a position above the lifter.
Abstract: A universal rolling mill stand of a demountable type having two pairs of adjustable rollers. One of the adjustable rollers has a pair of horizontal rollers and another has a pair of vertical rollers. The horizontal rollers and the vertical rollers are mounted demountably from a support base by a horizontal ring stand which is demountable from the base. A pair of lateral vertical side support structures slide apart in opposite directions from the pair of horizontal rollers such that an interior ring of a support roller bearing is retained on the rollers.
Abstract: A demountable rolling stand having a support base, a pair of rolling cylinders with necks formed thereon, two side structures for supporting the rolling cylinders laterally therebetween, at least two pairs of pretensioning tie-rods engaging the side structures so as to clamp the side structures to the cylinders. The side structures have cylindrical support roll bearings affixed thereto in support of the rolling cylinders. The necks of the rolling cylinders have an interior ring of the cylindrical support roll bearings affixed directly thereto such that the interior ring is removable along with the rolling cylinders. The support base is connected to the side structures so as to support the cylinders above a surface. The pretensioning tie-rods serve to pretension a rolling force between the cylinders.
Abstract: A bars packer plant having hung transfer magnets for packing bar layers differentiated in number including a single linear system of rotating hung transfer magnets movable between a position above a supply line with bar layers to be picked up to a position above a pack formation pocket. The transfer magnets rotate by turning upside down. A lifter is provided below the supply line and below the hung transfer magnets in a pick-up area. The lifter serves to lift one bar layer and attach it to a magnetic pickup surface above and below the hung transfer magnets, depending on the rotation of the magnetic pickup surface.
Abstract: An apparatus for moving rods to a packaging area and packing rods thereat which includes a conveyor for advancing movement of the rods between retractable stop members which are capable of separating the rods into rod layers. An upsetting mechanism is provided along the conveyor such that normal packing of selected layers of the rod layers can be disrupted to accommodate rods of varying shapes and sizes and the selected rod can fall subsequently downwardly into the packaging area. An electromagnetic transfer hanging mechanism is also provided for transferring the rod layers into the upsetting mechanism or depositing the same into the packaging area. The electromagnetic transfer hanging mechanism has at least two rows of electrtomagnets capable of vertically and horizontally moving the rod layers.
