Description

Technical Field

[0001] The utility model relates to the technical field of steel rolling, in particular to a steel rolling pushing structure. Background Art

[0002] Rolling is a metal processing process in which a metal billet is passed through the gap between a pair of rotating rollers. Due to the compression of the rollers, the cross-section of the material is reduced and the length is increased. It is a pressure processing method widely used in the steel processing industry.

[0003] The existing steel rolling process has the following disadvantages: a feeding assembly is generally provided during the steel rolling process to push the steel to be processed into the rolling mill. The existing steel rolling pushing assembly is generally large in size and complex in structure, and the pushing pressure rate is prone to change during the pushing process, affecting the rolling quality. For this reason, we propose a steel rolling pushing structure. Utility Model Content

[0007] Furthermore, it also includes a feeding mechanism, a feeding mechanism is provided on one side of the top of the hopper, and the feeding mechanism includes an inclined bin, a cylinder, a fixed plate, a baffle, a bracket and a partition, the top side of the hopper is fixedly connected to the inclined bin, the bottom of the inclined bin is installed with a cylinder and the power end of the cylinder is installed with a fixed plate, a baffle is installed on one side of the top of the fixed plate and the other side of the top of the fixed plate is fixedly connected to the partition through the bracket; an inclined bin is provided on one side of the hopper, and the steel rod components to be processed are put into the inclined bin and arranged side by side inside the inclined bin. Under normal conditions, the baffle blocks the steel rods and the partition is inserted into the fixed cover. After completing a single pushing operation, the push plate is reset, and the cylinder runs and its power end drives the fixed plate to descend. At this time, the partition first fits the surface of the steel rod to limit the downward displacement of the steel rod, and at the same time the baffle continues to move downward, so that a steel rod at the end of the inclined bin is discharged into the hopper, completing the automatic feeding operation, improving the working efficiency, and limiting the number of single feedings.

[0008] Furthermore, a guide wheel is installed at the bottom of the hopper near the feeding end of the rolling mill; the guide wheel structure plays a guiding role in the transportation of the steel bars.

Under normal conditions, the baffle 305 blocks the steel rods and the partition 307 is inserted into the fixed cover 302. After completing a single pushing operation, the push plate 206 is reset and the cylinder 303 runs its power end to drive the fixed plate 304 to descend. At this time, the partition 307 first fits the surface of the steel rod to limit the downward displacement of the steel rod. At the same time, the baffle 305 continues to move downward, so that a steel rod at the end of the inclined silo 301 is discharged into the hopper 201, completing the automatic loading operation, improving the working efficiency, and limiting the number of single loadings.

[0020] A guide wheel 207 is installed at the bottom of the hopper 201 near the feeding end of the rolling mill 1 ; the guide wheel 207 structure guides the transportation of the steel bars.

The ball nut 205 moves horizontally along the outer periphery of the screw rod 204 and pushes the steel bar through the push plate 206, pushing it into the interior of the rolling mill 1 for rolling. The screw rod 204 transmission component is smaller and simpler in structure than the existing chain-belt conveying structure. At the same time, it ensures that the thrust during the pushing process is stable, thereby ensuring the rolling quality. An inclined hopper 301 is provided on one side of 201.
