Abstract
The utility model discloses a water-cooling roll guide for an outlet of a pinch roll, which correctly guides high-speed wire rods or round steel from the outlet of the pinch roll to a spinning machine in the rolling process. The water-cooling roll guide comprises left and right guide box bodies connected into a whole body through a bolt, a guide roll shaft, a lining sleeve and a bearing, wherein 4-6 guide rolls are mounted on the left and right guide box bodies; a cooling coil pipe is mounted above the position between the two adjacent guide rolls; and a cooling water nozzle is mounted on the left or the right guide box body. The cooling coil pipe is mounted in a position far away from the wire rods or the round steel at the upper part of the left or the right guide box body, so that the potential safety hazard is removed. Under the action of the cooling coil pipe, the temperature of the guide rolls is reduced, the service lives of the guide rolls are prolonged, and the rolling cost is lowered.
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 high-speed rod in the operation of rolling or round steel correctly guided the guide and guard that get into Laying head from the 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 correctly guide the entering Laying head with 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, and 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, and cause guide and guard body and red steel contact area big; Self operating temperature is high, and with the red steel sliding friction of high-speed cruising, be easy to produce " steel bonding " phenomenon and wire rod or round steel be prone to take place to scratch phenomenon; Influence its surface quality, and the inner chamber wearing and tearing are also very fast, spare parts consumption is very big; Increased rolling cost, 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 under the environment of high temperature and is prone to fragmentation; Reduce significantly its service life simultaneously, guide and guards needs good cooling for this reason, discloses a kind of representative cooling system of rolling guide like 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, and 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 scheme of the utility model is achieved in that
The guide and guard of pinch rolls outlet water-cooled rolling; Comprise through bolt and be connected to holistic left and right sides guide and guard box body; On said left and right sides guide and guard box body, at the cavity first half of said left and right sides guide and guard box body four to six deflector rolls are installed evenly through guide roller axis, lining and bearing, the outer circumference surface of said deflector roll is processed into the product cross section shape of required guiding; It is characterized in that: above on said left guide and guard box body or the right guide and guard box body, between said 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, said 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 explain the utility model, but are not used for limiting the scope of the utility model, and all technical schemes that are equal to also belong to the category of the utility model, and the scope of patent protection of the utility model should be limited each item claim.
From Fig. 1 and 2, can find out; The guide and guard of pinch rolls outlet water-cooled rolling; Comprise through bolt 3 and be connected to holistic left guide and guard box body 1 and right guide and guard box body 2; On said left guide and guard box body 1 and right guide and guard box body 2, at the cavity first half of said left guide and guard box body 1 and right guide and guard box body 2 four-six deflector rolls 7 are installed evenly through guide roller axis 4, lining 5 and bearing 6, the outer circumference surface of said deflector roll 7 is processed into the product cross section shape of required guiding; Above on said left guide and guard box body 1 or the right guide and guard box body 2, between said adjacent two deflector rolls 7, cooling coil 8 is installed; On the left guide and guard box body 1 of said correspondence or right guide and guard box body 2, cooling water is installed and chews 9, said cooling water is chewed 9 and is linked to each other with cooling coil 8.
At work; Wire rod that pinch roll is seen off or round steel are directed to said wire rod or round steel in the Laying head, through the effect of cooling coil 8 through 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.
Claims (1)
