Abstract
The utility model discloses a water nozzle scratch preventing device, which comprises a nozzle arranged on a fixed bracket, wherein the bottom of the nozzle is provided with a supporting roller, and the supporting roller is arranged on the bottom of the nozzle through a shaft and a bearing. The nozzle is arranged on the fixed bracket through a hand wheel assembly. The end part of the shaft is provided with an oil gas nozzle. The oil gas nozzle is arranged on the end part of the shaft to lubricate the bearing so as to prolong the service life of the bearing and reduce the abrasion of a guide wheel. According to the water nozzle scratch preventing device, surface scratch caused by the sliding friction between wire stock and the nozzle in a rolling process can be reduced or prevented, and the surface quality of the steel wire stock is improved.
Description
Technical field
The utility model relates to a kind of abrasive device of (operating) water nozzle that prevents, specifically a kind of abrasive water-cooled line of wire surface water-cooled nozzle scratching device that prevents.
Background technology
In the production process of wire rod, water tank generally is comprised of nozzle, and wire rod reaches the temperature that needs after the water tank cooling.In the prior art, contact between nozzle and the wire rod all is sliding-contact, and in the operation of rolling of wire rod, sliding-contact will form sliding friction, and sliding friction easily produces scuffing on the surface of wire rod, occur in before the finish to gauge frame owing to scratch, if scuffing is darker in the middle of this, through behind lower a time mill milling, it is folding often to form poker, product inspection personnel naked eyes are difficult to find that the consequence of bringing thus is the mechanical performance that affects wire rod, even produce waste product.
Summary of the invention
The shortcoming that exists in order to solve prior art, the purpose of this utility model provides a kind of abrasive device of (operating) water nozzle that prevents, this device can reduce or prevent the surface tear that wire rod brings with nozzle generation sliding friction in the operation of rolling, improve the surface quality of wire rod.
The purpose of this utility model is achieved through the following technical solutions:
A kind of abrasive device of (operating) water nozzle that prevents comprises the nozzle that is arranged on the fixed support, and it is characterized in that: be provided with support roller at nozzle bottom, support roller is installed in nozzle bottom by axle and bearing.
In the utility model, described nozzle is installed on the fixed support by locating hole.Nozzle is arranged on the fixed support by the handwheel combination.Be provided with the oil gas mouth in the end of axle.The oil gas mouth is installed in the end of axle, and bearing is lubricated, and improves its service life, reduces the guide wheel wearing and tearing.
Support roller described in the utility model also can be guide wheel.
The utility model has the advantages that: the utility model can reduce or prevent the surface tear that wire rod brings with nozzle generation sliding friction in the operation of rolling, improves the surface quality of steel wire rod.After the utility model use, scuffing significantly reduces, and the wire surface quality obviously improves, and large wire rod scuffing ratio contrasted such as table 1 before and after the utility model came into operation:
Table 1
| Lot number | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | On average |
| Before scuffing rate %(uses) | 17.12 | 19.53 | 21.56 | 16.85 | 18.1 | 14.76 | 16.46 | 18.49 | 17.86 |
| After scuffing rate %(uses) | 0.56 | 0.53 | 0.42 | 0.66 | 0.41 | 0.51 | 0.32 | 0.4 | 0.48 |
