Abstract

The utility model discloses a pre-inlet guide device characterized in that the pre-inlet device comprises 3-5 groups of lower guide rolls (4) which are fixed and upper guide rolls (14) which can be adjusted vertically, the diameter and length of each group of guide rolls are equal, the guide rolls are fixed with guide roll spindles by glands and hexagon socket head bolts via bearings of guide rolls, lower guide rolls (17) are fixed on a fixed bracket (1) via lower guide roll spindles, upper guide rolls are fixed on a movable bracket (10) via upper guide roll spindles (8). The utility model has the advantages that the rolled pieces can be automatically corrected during the segmentation and rolling process of the ribbed steel bars, the wear of pre-econ is symmetrical, the on neutral of rolled piece is good, and the final product quality is steady.

Description

Pre-inlet guide and guards

Technical field

The utility model relates to the guide and guards that the Ribbed Bar cutting rolling technology is adopted, especially a kind of pre-inlet guide and guards that adopts between mm finishing mill unit in 3, the 4 line splitting and rolling technology.

Background technology

At present, the most manufacturers of the rolling technique of Ribbed

Bar

3,4 line cuttings adopt circular hole at last rolling mill pass of middle milling train group, and the finish rolling first rolling mill pass adopts plain-barreled roll.This pass rolled piece therefrom last rolling mill of milling train group comes out to enter mm finishing mill unit first rolling mill and is easy to, and does not need the special inlet device of design and installation.But exist the precutting hole wearing and tearing uneven, it is relatively poor to neutrality that rolled piece enters precutting hole, causes many rolled piece sectional areas after separating to differ greatly, and finished product is prone to problems such as defective.

The utility model content

The purpose of this utility model is to overcome above-mentioned shortcoming and can guarantees the stable pre-inlet guide and guards of end product quality from the dynamic(al) correction rolled piece in a kind of Ribbed Bar splitting rolling process of providing.

The purpose of this utility model and solve its technical problem underlying and realize by the following technical solutions: pre-inlet guide and guards of the present utility model, comprise that 3～5 groups of lower guide rolls 4 are fixing, the pre-inlet device that last deflector roll 14 can vertically be adjusted up and down, the diameter of every group of deflector roll and equal in length, deflector roll and guide roller axis are fixed with gland and hexagon socket head cap screw by the deflector roll bearing, lower guide roll 17 is fixed on the fixed mount 1 by lower guide roll axle 4, and last deflector roll 14 is fixed on the movable stand 10 by last guide roller axis 8.

The purpose of this utility model and solve its technical problem and can also adopt following technical measures further to realize.

Last deflector roll 14 is fixed by last deflector roll bearing 9 usefulness gland B7 and hexagon socket head cap screw B6 with last guide roller axis 8, last deflector roll is positioned at fixed mount 1, last guide roller axis 8 passes movable stand 10 axis holes and fixed mount 1 usefulness nut B15 is locked, movable stand 10 has a circular hole by screw rod 13, uses fixedly movable stand 10 of hold-down bolt 11; Lower guide roll 17 is fixed by lower guide roll bearing 5 usefulness gland A3 and hexagon socket head cap screw A2 with lower guide roll axle 4, and lower guide roll is positioned at fixed mount 1, and lower guide roll axle 4 passes fixed mount 1 axis hole and lower guide roll is locked with nut C16.

During use, last rolling mill of middle milling train group adopts square hole, and flat hole is adopted in first of finish rolling, this device be installed in rolling line in, between smart unit by the mm finishing mill unit first rolling mill porch.

The utility model is compared with prior art: last rolling mill of middle milling train group adopts square hole, flat hole is adopted in first of finish rolling, laggard to go into the flat hole of finish rolling first rolling mill rolling from dynamic(al) correction with rolled piece to shut out the effect by deflector roll of the square rolled piece that comes during the utility model can make, to guarantee the rolling smoothly of back passage rolled piece, prevented that effectively square rolled piece diagonal angle mm finishing mill unit first rolling mill of nipping from causing the heap steel or producing the defective that major part causes end product quality, have precutting hole wearing and tearing evenly, rolled piece is good to neutrality, the advantage that end product quality is stable.

The specific embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
