(54) HOT BAND MOTOR

I

The invention relates to the processing of metals by pressure, in particular to the production of rolling hot rolled sheet.

A hot strip winder is known, containing wiring mounted on the frame, at the exit of which a drum is placed with restrictive rollers located around it, associated with cardan drives of their rotation and translational movement. From the slide gate to the reel drum, self-operating sheet metal wiring 1 is mounted.

However, during installation, and then during operation, gaps are formed between these wiring, which are difficult to adjust. When the sheet metal moves, the front end of it gets into the resulting gap between the conductors, causing the strip to be drilled in the wiring reinforcement, which leads to the removal of the mechanisms of the winder, the downtime of the mill and the failure of the sheet metal. In addition, after strip stripping, a large amount of repair work is required to restore the broken winder parts, which leads to additional mill downtime. Repair work is carried out in cramped conditions and at high temperatures.

A hot strip winder is also known, containing wired reinforcement mounted on a bed consisting of a guide gate, medium wiring with stiffening ribs on its external sides and swinging wiring, the output of which is a drum with forming rollers 2 arranged around it.

By performing an average posting with. stiffening ribs increase the durability of its work, however, the possibility of drilling the strip remains very high, which leads to a decrease in productivity.

The aim of the invention is to increase productivity by eliminating strip drilling in wired reinforcement.

This goal is achieved by the fact that the coiler has a hot strip containing wired reinforcement fixed to the frame, consisting of a guide bolt, medium wiring with stiffening ribs on its external sides and swinging wiring, at the exit of which a drum is installed with rollers, the middle wiring is made with a cross-section in the form of a closed rectangle, the lower part of the guide gate and the upper part of the middle wiring are made in the form of combs, while the protrusions of the comb are About the gate of the mate with the grooves of the comb of the average wiring.

FIG. 1 depicts the proposed winder; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows the node I in FIG. one; in fig. 4 is a view B in FIG. 3

The hot strip winder contains a bed of 1 dl of mounting of all mechanisms, a winding drum 2 driven by an electric motor (not shown) forming rollers 3 arranged around the winding drum to form a lower roller 4 and a upper roller 5 for feeding the strip into the coiler, wiring armature made in the form of a guide gate 6 for guiding the movement of the strip to the coiler winding coiler, middle wiring 7 made of sheet metal with a closed cross section p rectangle, rocking wiring 8 prior to forming rollers. In order to stiffen the middle wiring structure 7, it is provided with side walls 9, and the top and bottom walls on the outer side have stiffeners 10. In order to provide access to the winder mechanisms and carry out repairs, the average wiring 7 in its upper part is fixed on the frame 11 of the mill on the mill The hinges allow turning the center wiring in the direction perpendicular to the axis of the drum. To prevent the strip from being drilled at the moment of its beginning in the wiring fittings, the connection of the guide gate 6 with the middle wiring 7 is made in the form of a comb.

The winder works as follows.

Before approaching the rolled strip from the mill to the coiler, the winding drum 2 is accelerated to the required speed. The cassettes with the rollers are driven by the drive mechanism to the drum, the forming rollers 3 are mounted around the cylindrical surface of the drum with the required clearance. The hot strip with the roller mill falls between the lower feed roller 4 and the upper feed roller 5, using a guide gate b, it is directed to the middle wiring 7. and then to the swing wiring 8 in front of the forming rollers. By combining the separately working wiring into one solid middle wiring 7 and connecting it in the form of a comb with guide gate 6, the gaps between the wiring are eliminated and the strip is not drilled. Approach to the winding drum, the strip is captured in the gap between the first shaping roller and the drum and guided around the circumference of the drum successively to the other shaping rollers. As the strip is wound into a roll, the forming rollers are pressed out of the outer forming roll.

When the coiler operates, cooling liquid is supplied to the strip, roll and mechanisms. After winding the entire strip into a roll, the winder stops, the forming rollers are retracted by a drive mechanism, and the coiled roll is removed using a special trolley. The coiler is again ready to repeat the work cycle.

The introduction of the device on only one broadband continuous mill “2000 will provide savings of 177,730 rubles. in year.
