Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so as to help understand the content of the present invention.

[0019] like figure 1 As shown, it is a schematic diagram of an active and passive cold-rolled ribbed steel bar production device, including a driven rolling mill 1, including a pair of parallel reducing rolls 11a, 11b installed on the stand 12, which adopts direct rolling and is used for To achieve cold extrusion relief for the wire rod, no power unit is required. There is also a driving rolling mill 2 installed downstream of the driven rolling mill 1 .

[0020] combine figure 2 As shown, the active rolling mill 2 includes a pair of parallel profiled rolls 21a, 21b installed on a stand 22, and patterns for rolling ribs are provided on the profiled rolls. The main motor 6 realizes deceleration output by the reducer 5 through the pulley and the belt, the reducer 5 is connected wit...

Abstract

The invention discloses a main passive cold rolling production device of a steel bar with rib, which characterized in that the device comprises an active rolling mill and a passive rolling mill which is arranged on the upper position of the active rolling mill. The active rolling mill comprises a forming roller arranged on the frame base. The forming roller is provided with patterns required for grinding the rib of the steel bar. The forming roller is driven by the main motor through the transmission mechanism. The passive rolling mill comprises a roller of reducing diameter arranged on the frame base which is used for extruding and reducing diameter to the raw materials. The production device has the advantages of stable and realizable operation with high production efficiency.

Description

technical field [0001] The invention relates to a kind of mechanical equipment, specifically a device for producing steel bar, which is composed of active rolling mill and passive rolling mill, so as to form ribbed steel bar after hot-rolled wire rod is reduced in diameter and ribbed by cold rolling. Background technique [0002] Cold-rolled ribbed steel bar is a new type of construction steel product that developed rapidly at home and abroad in the late 20th century. Because it has the characteristics of high strength, good plasticity, easy processing and strong binding force with cement, and can save a lot of steel, it has been valued by the relevant departments of the state, and it is clearly stipulated that it will gradually replace hot-rolled grade I smooth round steel bars and eliminate low-carbon steel cold-drawn wires. . [0003] At present, the production of ribbed cold-rolled steel bars adopts a three-roll structure, and the three rolls are arranged at 120°. The ...
