Abstract
The utility model relates to a device for preventing steel wires from scratching. The device comprises a guide groove; and a riding wheel or an idler pulley is arranged at the bottom part of the guide groove. The device can reduce or prevent the surface scratch of steel wires caused by sliding friction with the guide groove in rolling process and improve the surface quality of the steel wires.
Description
Technical field
The utility model relates to a kind of steel wire scratching resistant device.
Background technology
In the production process of steel wire rod, between milling train and the milling train, between milling train and other equipment,, all be by the guide groove transition if distance is longer.Big wire rod production line as shown in Figure 1, the about 15m of distance between 4# water tank 1 and the 5# water tank 2, camber line transition, the about 20m of distance between 5# water tank 2 and the 2# flying shear 3, straight transitions.In the prior art, contact between guide groove and the steel wire rod all is sliding-contact, and in the operation of rolling of steel wire rod, sliding-contact will form sliding friction, and sliding friction is easy to generate scuffing on the surface of steel wire rod, occur in before the finish to gauge frame owing to scratch, if scratch in the middle of this darker, through behind a time mill milling down, 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 influences steel wire rod, even produce waste product.
Summary of the invention
Technical problem to be solved in the utility model is: at the shortcoming of above prior art existence, propose a kind of surface tear that can reduce or prevent that steel wire rod from bringing with guide groove generation sliding friction in the operation of rolling, improve the steel wire scratching resistant device of the surface quality of steel wire rod.
The technical scheme that the utility model solves above technical problem is: the steel wire scratching resistant device, comprise guide groove, and the guide groove bottom is provided with support roller or guide wheel.
Steel wire scratching resistant device of the present utility model also is provided with bearing, fixed support and eccentric shaft, and fixed support is located at the guide groove below, and bearing is installed on the fixed support by bolt, and eccentric shaft is installed on the bearing, and support roller or guide wheel are installed on the eccentric shaft by bearing.In addition, also be provided with the oil gas mouth, the oil gas mouth is installed in the end of eccentric shaft.
The utility model has the advantages that: the utility model can reduce or prevent the surface tear that steel wire rod brings with guide groove 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 steel wire rod surface quality obviously improves, and big wire rod scuffing ratio contrasted as following table before and after the utility model came into operation:
Table 1
| Lot number | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | On average |
| Scuffing rate % (before using) | 18.12 | 20.53 | 22.56 | 17.85 | 19.1 | 15.76 | 18.46 | 21.49 | 18.95 |
| Scuffing rate % (using the back) | 0.55 | 0.43 | 0.46 | 0.65 | 0.31 | 0.31 | 0.42 | 0.5 | 0.47 |
