Abstract
The utility model discloses a water cooling rolling guide at a pinch roll outlet which correctly guides the high speed wire or round steel in the rolling process from the pinch roll outlet to a wiring laying machine, including left and right guide box bodies connected into a whole by a bolt; four to six guide rollers are installed on left and right guide box bodies through the guide roll shaft, the lining and the bearing; a cooling coil pipe is installed on the top between adjacent guide rollers; a cooling water nozzle is installed on left or right guide box body; the cooling coil pipe is installed on the upper portion of left or right guide box body and is far away from the operation position of the wire or the round steel so as to eliminate the safety hidden trouble. The cooling coil pipe reduces the temperature of the guide roller, prolongs its service life and decreases the rolling cost.
Description
Technical field
The utility model relates to the critical component in a kind of rolled wire process, relates in particular to a kind of guide and guard that high-speed rod in the operation of rolling or round steel are entered Laying head from the correct guiding of outlet of pinch roll.
Background technology
The pinch rolls outlet guide and guard are critical components that high-speed rod or round steel advance Laying head, and it can enter Laying head with the correct guiding of rolled piece, and its state quality is directly connected to the surface quality of finished product wire rod or round steel.
Because traditional pinch rolls outlet guide and guard in the past are slip forms, the cavity shape of guide and guard body is simple, inner chamber is processed into the cross sectional shape of wire rod or round steel, in the course of the work, wire rod or round steel slide in inner chamber and advance, cause guide and guard body and red steel contact area big, self operating temperature height, and with the red steel sliding friction of high-speed cruising, be easy to produce " steel bonding " phenomenon and wire rod or round steel are easily scratched phenomenon, influence its surface quality, and the inner chamber wearing and tearing are also very fast, spare parts consumption is very big, has increased rolling cost, and domestic and international many steel rolling mills adopt rolling guide to solve this technical barrier.But temperature is higher when passing through owing to workpiece, deflector roll is worked easily broken under the environment of high temperature, reduce significantly its service life simultaneously, guide and guards needs good cooling for this reason, a kind of representative cooling system of rolling guide is disclosed as Chinese utility model patent ZL97211967.1, the input that is cooling water is between two deflector rolls, the run location of input position and workpiece is close, the structure of this cooling and the connection of pipeline thereof cause confusion to the working site, will cause security incident when serious.
The utility model content
The utility model purpose is to provide a kind of pinch rolls outlet water-cooled rolling guide and guard of new structure, in the superjacent air space between 2 deflector rolls that the delivery channel rear end of pinch roll is installed cooling coil is installed, the installation site of cooling coil eliminates safe hidden trouble away from the run location of workpiece.
The technical solution of the utility model is achieved in that
The guide and guard of pinch rolls outlet water-cooled rolling, comprise by bolt and be connected to holistic left and right sides guide and guard box body, at the cavity first half of described left and right sides guide and guard box body four to six deflector rolls are installed evenly by guide roller axis, lining and bearing on described left and right sides guide and guard box body, the outer circumference surface of described deflector roll is processed into the product cross section shape of required guiding; It is characterized in that: above on described left guide and guard box body or the right guide and guard box body, between described adjacent two deflector rolls, cooling coil is installed, and on the left guide and guard box body of correspondence or right guide and guard box body, cooling water is installed and chews, described cooling water is chewed with cooling coil and is linked to each other.
The utility model compared with prior art has following advantage:
1. cooling coil is installed in the top of right guide and guard box body, away from wire rod or round steel run location, eliminates safe hidden trouble.
2. the shared cooling coil of two adjacent deflector rolls, one side can be saved the quantity of cooling coil, reduces the production cost of guide and guard, can reduce the height of guide and guard on the other hand to greatest extent.

The specific embodiment
Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model, and all technical schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by every claim.
From Fig. 1 and 2 as can be seen, the guide and guard of pinch rolls outlet water-cooled rolling, comprise by bolt 3 and be connected to holistic left guide and guard box body 1 and right guide and guard box body 2, at the cavity first half of described left guide and guard box body 1 and right guide and guard box body 2 four or six deflector rolls 7 are installed evenly by guide roller axis 4, lining 5 and bearing 6 on described left guide and guard box body 1 and right guide and guard box body 2, the outer circumference surface of described deflector roll 7 is processed into the product cross section shape of required guiding; Above on described left guide and guard box body 1 or the right guide and guard box body 2, between described adjacent two deflector rolls 7, cooling coil 8 is installed, on the left guide and guard box body 1 of described correspondence or right guide and guard box body 2 cooling water is installed and chews 9, described cooling water is chewed 9 and is linked to each other with cooling coil 8.
At work, wire rod that pinch roll is sent or round steel are directed to described wire rod or round steel in the Laying head, by the effect of cooling coil 8 by the rolling of the deflector roll 7 of differing heights on left guide and guard box body 1 and the right guide and guard box body 2, reduce the temperature of deflector roll 7, prolong its service life.
