Novel rolling prebending device

Abstract

The invention discloses a novel rolling prebending device. An all-guide-roller structure is adopted to solve the problem that an existing power prebending device can scratch the surfaces of wire rods. A major structure of the novel rolling prebending device is formed by a base plate (8), a clamp plate (9) and guide rollers (10). Every four guide rollers (10) are fixed between the clamp plate (9) and the base plate (8) through guide roller shafts (11) to form one group. A plurality of groups are connected to form a prebending path. A group of guide roller bearings (15) and an oil distributing ring (18) are arranged in each guide roller (10). A cooling water pipe (12) is additionally arranged above the guide rollers (10). Water retaining rings (17) are installed on two sides of each guide roller bearing (15). An oil-gas lubrication connector (13) is installed at an opening end of each guide roller shaft (11). An outer end of the each oil-gas lubrication connector (13) is communicated with a hosepipe (16) of an oil-gas lubrication device. An inner end of each oil-gas lubrication connector (13) is communicated with a middle oilhole and the oil distributing ring (18) in each guide roller shaft (11). The prebending path comprises an inlet straight line AB section, a bending curve BC section and an outlet straight line CD section. The novel rolling prebending device basically eliminates scratches of the wire rods generated in the prebending device. The surface quality of the wire rods is obviously improved.

Description

technical field [0001] The invention belongs to steel rolling equipment, in particular to a novel rolling pre-bending device. Background technique [0002] The high-speed wire rod production equipment completed and put into operation in 2010 has large scale, sophisticated equipment, and new technology, and has a high-level production capacity of special steel long sections. The existing power pre-bending device of the high-speed wire rod mill is designed and manufactured by Morgan Company of the United States, and is located between 4WB2 (No. 2 water tank at RSM exit) and the intelligent pinch roller; into intelligent pinch rolls and laying heads. Such as figure 1 As shown, there are four groups of guide rollers and five groups of sliding guide devices inside the existing power pre-bending device. The diameter of the guide rollers is 300mm, and the rotation is driven by a frequency conversion motor. Morgan's design concept is that after the wire enters the power pre-bendi...
