Description

Technical Field

[0001] The invention relates to the technical field of conveying equipment, and in particular to a feeding device for round steel production. Background Art

[0002] Round steel refers to solid long strips of steel with a circular cross-section. The traditional round steel production process mainly includes raw material preparation-melting-casting-hot rolling-cooling-finishing (pickling, cutting, etc.)-quality inspection. In order to further improve the strength, dimensional accuracy and surface quality of round steel, it is necessary to add a cold drawing process after cooling. The cold drawing process is to send the hot-rolled round steel into a drawing machine for drawing. By continuously adjusting the pulling force and speed of the drawing machine, the round steel is gradually thinner and its surface finish is improved. After multiple drawing, the round steel is sent to the final rolling mill for final processing to further improve the strength, dimensional accuracy and surface quality of the round steel.

[0003] The hot-rolled round steel is fed into the drawing machine for drawing. The traditional feeding method is to use a V-shaped conveyor trough to convey the round steel. However, when the diameter of the produced round steel changes, it is necessary to stop the machine to adjust the matching position of the V-shaped conveyor trough and the drawing machine so that the conveyed round steel is coaxial with the drawing position of the drawing machine.

[0043] When feeding round steels of different diameters, the rotating motor is driven to move through the PLC controller, and the rotating motor drives the feeding roller 51 to rotate. The feeding roller 51 rotates to turn the adapted material guide base 52 to the top for feeding, thereby achieving precise alignment of round steels of different diameters with the drawing machine, without stopping the machine to adjust the corresponding position, and with high alignment accuracy.
