JPS5935287Y2 - Side looper in wire rod rolling equipment - Google Patents

Description

[Detailed explanation of the invention] The invention is based on the wire rod rolling stage vN! Specifically, the objective is to provide a suitable side looper (hereinafter referred to as a looper) by arranging the pass line in the fM direction at the rolling mill Yumachi.

In wire rod rolling equipment, due to the layout of the rolling equipment, the pass line may be offset from the middle, or, for example, as shown in Fig. The pass line P is slightly biased between intermediate rolling mill row I and finishing rolling mill row ■, which are arranged in When connected by a guiding trough, the rolled material running on the pass line is biased in its running direction, causing resistance while running inside the guiding trough, and as a result, the rolled material runs in the looper. The rolled material becomes bent and flows in the direction perpendicular to the pass line inside the looper.
Taxi or excessive loops occur in the rolled material, which not only makes rolling unstable and reduces product yield, but also
This caused misrolls to occur.

The present invention was devised in view of the above-mentioned points, and its feature is that in a looper that is placed between rolling mills or between rows of rolling mills and forms a loop in the wire rod, the looper is located at an intermediate position of the wire rod pass line of the looper. The invention consists in that an auxiliary guide is provided with an inclined surface formed on the edge parallel to the pass line.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A looper in a wire rod rolling facility according to the present invention will be described below based on the illustrated embodiment.

10 is a fire bar, which has a smooth loop floor 11 for forming a loop of the rolled material S, and has a smooth loop floor 11 on its entry side, which cooperates with a kick roller 13 to be described later to hold the loop when forming the loop of the rolled material. A guide roller 12 is installed upright, and a guide groove 1 is cut into the loop floor 11 from the outside of the side plate 14 of the looper.
A kick roller 13 is provided within the loop bed 11 and is provided with a kick roller 13 which is driven to move forward and backward by an appropriate drive means, and a sloped surface is provided on the side edge parallel to the pass line (indicated by a broken line in the figure) of the rolled material that falls on the loop bed 11. An auxiliary guide 16 having a number 17 is fixed to the loop bed 11.

This auxiliary guide 16tj: has a substantially ship-like shape with a portion parallel to the pass line and a sharp portion at the front and back in the direction of progress of the rolled material in plan view, and the inclined surface 1T is an ascending slope.

In the figure, reference numeral 18 is a guide of the rolling mill that leads to the entrance side K of the looper 10, and reference numeral 19 is a guide trough that guides the rolled material S to the finishing rolling mill row.

According to the luaper according to the present invention having the above-described configuration, the rolled material S leaving the intermediate rolling mill row enters the looper 1 orc, passes through the pass line, enters the guide trough 19, and travels toward the finishing rolling mill row. However, the rolled material S whose running direction is biased after leaving the intermediate rolling mill row generates resistance in the guide trough 19, and as a result, the loop bed 1 in the looper 10
1 in a direction that intersects the pass line, but it is restrained by the auxiliary guide 16 arranged parallel to the pass line, and the rolling material S is held without being obstructed. The kick roller 13 is operated at the moment when the rolled material S is bitten into the finish rolling mill row to form a loop in the rolled material.

Due to the operation of the kick roller 13, the rolled material S starts to move laterally from the pass line in the looper 10 and hits the auxiliary guide 16 provided parallel to the pass line.
The side surface of this auxiliary guide 16 is an inclined surface 17 that becomes an upward slope.
Since the rolled material S is formed in the auxiliary guide 16vc
The rolled material S moves on the inclined surface 17 without getting caught, in other words, the rolled material S climbs over the auxiliary guide 16 and reaches the loop bed 1.
It will move to 1.

As is clear from the above explanation, according to the present invention, when the pass line of the rolled material is deflected midway, the looper at that position can be used to prevent the rolled material from buckling when running. In order to ensure the running of the rolled material, it is possible to prevent the rolling material from taxiing in the looper and avoid misrolling, and the effects such as improving productivity are significant.
