Benefits of technology

[0024]According to another embodiment of this aspect of the invention, when no piece of stock is detected between the guide rollers, the lateral distance between the guide rollers is increased such that free passage of a first end of a piece of stock between the guide rollers is allowed.

Problems solved by technology

However, a problem with such known roller guides is that the guide rollers are heavily worn due to the large forces resulting when the stock enters between the guide rollers.

Embodiment Construction

[0033]A schematic illustration of a roller guide 1 according to an embodiment of the present invention is shown in FIG. 1-4. The roller guide 1 is intended for guiding stock in a longitudinal feeding direction A in a rolling mill, primarily toward a pair of rolls for shaping the stock. The roller guide 1 comprises a frame arrangement 2 and a pair of guide rollers 3, 4, each guide roller 3, 4 being mounted on an arm 5, 6 of the frame arrangement 2. The arms 5, 6 are pivotable and movable such that a lateral distance, i.e. in a direction perpendicular to the feeding direction A, between the guide rollers 3, 4 can be adjusted. The guide rollers 3, 4 are rotatable about parallel axes of rotation C3, C4 perpendicular to the longitudinal feeding direction A and to the lateral direction. The roller guide 1 further comprises a control unit 7 in which positioning means for adjusting the lateral distance between the guide rollers 3, 4 by means of moving and pivoting the arms 5, 6 is comprised...

Abstract

A roller guide (1) for guiding stock in a longitudinal feeding direction (A) toward a pair of rolls for shaping the stock. The roller guide comprises a frame arrangement (2), a pair of guide rollers (3, 4) configured to, in a closed position, engage opposite surface portions of the stock,and positioning means for adjusting a lateral distance between the guide rollers. The roller guide further comprises detection means (13) configured to detect a longitudinal position of a piece of stock (20) with respect to the guide rollers. The positioning means is configured to adjust the lateral distance between the guide rollers in response to said detection.

Description

TECHNICAL FIELD[0001]The invention relates to a roller guide for guiding stock in a longitudinal feeding direction toward a pair of rolls for shaping the stock according to the preamble of claim 1 and to a method for guiding stock according to the independent method claim. In particular, the invention relates to a roller guide and to a method for use in the production of wire, rods and beams.BACKGROUND AND PRIOR ART[0002]Roller guides are commonly used for guiding hot stock, such as wire stock or rod stock, in rolling mills. Primarily, roller guides are placed before a pair of rolls used to shape the stock, so called entry roller guides. These roller guides guide the stock which is to be rolled toward a particular rolling groove. The use of roller guides reduces the risk of damaging the stock upon entry between the pair of rolls and enables feeding the stock at high feeding rates.[0003]U.S. Pat. No. 3,935,722 discloses a roller guide for guiding stock toward a pair of rolls. The rol...
