Description
Technical Field
[0001] The present application relates to the field of steel rolling inlet guides, and in particular to a rolling inlet guide capable of adjusting the position of a bar finishing mill. Background Art
[0002] Finishing mill is an important equipment for rolling alloy and non-alloy steel, seamless steel pipe, wheel strip steel and various cross-sectional shapes of bearing steel, spring steel and other materials. Typically, bar finishing mill is one of them.
[0003] In the current field of bar rolling, especially in the production of small-sized bars, various rolling inlet guides are often used to enable the bars to accurately and stably enter and exit the roll hole; the guide design on the market is usually based on the largest roll diameter. At this time, the inlet guide and the rolling groove on the roll surface will be set closer, so there will be a better rolling effect.
[0004] However, as production continues, the rollers will continue to wear. When the rollers are worn to the point of being unusable, they are usually removed and sent to the lathe in the machine repair shop for turning and repair. The diameter of the rollers after turning and repair will be much smaller than the diameter of new rollers, but the installation position of the imported guides is usually fixed, and the installation position of the rollers is also fixed. This results in that when the repaired rollers are used, the imported guides will be far away from the rolling grooves on the outer surface of the rollers, which will lead to frequent production accidents.
[0005] Therefore, how to make the distance between the inlet guide and the roller adjustable is a practical problem that needs to be solved urgently. Utility Model Content
