Abstract

PURPOSE:To make the inlet and outlet of a wire rod changeable by providing a wire rod guide for advancing in one way on a swiveling table which reverses the inlet and outlet of said guide. CONSTITUTION:A wire rod guide 2' is so constituted so as to form arcs AB, A'B' on a prescribed arc line. The wire rod entering toward the arrow (a) enters the guide 2' through an inlet A of the guide 2', emerges toward the arrow (b) by passing through an outlet B and is accumulated in an accumulating device or the like. When the wire rod is supplied from the accumulating device, the wire rod enters toward the arrow (c) and therefore the guide 2' is swiveled toward the arrow (d), i.e., toward the right and is stopped in the position A' where there had been the outlet B beyond the inlet A. On the other hand, the outlet B is stopped in the position B'. The wire rod supplied toward the arrow (c) in this state enters the inlet A' and emerges toward the arrow (e) from the outlet B'.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is a line for manufacturing wire rods of steel, copper, aluminum, etc., in which wire rods in the process of being manufactured are temporarily accumulated outside the line for buffering, heat treatment, etc. .

This relates to a wire rod selector guide used when feeding the wire rod to the wire rod line again.

(Conventional technology) First, a conventional wire guide will be explained.

As shown in FIG. 1, the wire guide tube l is usually 1.

To smoothly guide the tip of the entering wire.

The entrance is wide and the exit is narrow. The wire guide cylinder 17i - As shown in FIG. 2, a plurality of wire guides 2 are arranged in the same direction, and the traveling direction of the wire is determined to be one direction. Its usage form is to move the wire guide 2 as shown by arrow C around the entrance point or exit point of the wire rod guide as the center of rotation, and to have a path branching function in which only the exit or entrance position of the wire rod can be changed. For example, in a wire rod rolling line 1 shown in FIG. 3, it is used as a wire rod selector guide 16 for branching. The wire rod rolling line shown in Fig. 3 consists of three rows of rough rolling mills and four rows of intermediate rolling mills. First selector guide 16A.

It consists of two finishing rolling mill rows 5a and 5b, a second selector guide 16B, and a wire winding device 6.

As exemplified below, in the conventional wire rod rolling line, there was only a need for path branching, and the selector guide 16 shown in FIG. 3 sufficiently satisfied that function.

However, recently, with the advancement of wire rod manufacturing technology, for example, in wire rod rolling lines, measures are taken to reduce rolling and '1'/H during manufacturing of small diameter wire rods, and in-line processing heat treatment in the finishing rolling process. An intermediate material storage device is provided between the rough rolling mill row 3 and the intermediate rolling mill row 4 in FIG. 3, or between the intermediate rolling mill row 4 and the finishing rolling mill rows 5a and 5b, and Between mill rows 4 or intermediate rolling mill row 4
There is a strong demand for rolling equipment that can interrupt the continuity of rolling between the finishing mill rows 5a and 5b.

When installing an intermediate material storage device or heat treatment device in the middle of a rolling line with the premise of interrupting the continuity of rolling, the wire rods enter the device and the wire comes out of the device. Since the moving direction of the wire rod is exactly opposite, in the conventional selector guide 16, the wire rod enters from the exit of the wire rod, and the tip of the wire rod hits the guide tube l, making it impossible to reed the appropriate material. Therefore, in such a case.

Since the conventional selector guide position Hi has a function of switching only the exit or entrance position as shown in FIG. 2, it cannot meet the above requirements.

(Object of the invention) Therefore, the present invention makes it possible to change the entrance and exit of the wire,
Furthermore, the present invention aims to provide a selector guide whose exit position can also be changed.

(Structure and operation of the invention) The present invention provides a wire rod selector guide characterized in that a unidirectionally advancing wire rod guide is provided on a revolving table that reverses the entrance and exit of the wire rod kite on the wire rod passage line. It is.

The present invention will be specifically explained below with reference to the drawings.

FIG. 4 shows the operating state of the selector guide of the present invention]
- This is an explanatory diagram. In this example, the wire guide 2' is configured to form bullets B, A'B' on a predetermined arc line. In FIG. 4, the wire rod coming in the direction of arrow a enters through the entrance A of the wire rod guide 2', passes through the exit 13i, and exits in the direction of the arrow 1. For example,
The material is stored in a material storage device (not shown). Next, when feeding the wire from the material storage device (not shown in 5), the wire comes in the direction of arrow C, so before that, the wire rod guide 2'
Turn to the right in the direction of arrow d, that is, to the right in the figure, and stop at position A' where exit B was. On the other hand, exit B is
Stop at position . In this state, the wire supplied in the direction of arrow C enters the inlet, exits from the outlet B', and exits in the direction of arrow C. In this way, the entrance of the wire is always the entrance of the guide A, A', that is, the wide hole of the guide tube (I
ll G, so the tip of the wire that enters and goes around can be smoothly inserted into the appropriate material without getting caught in the entrance.

Next, a method for enabling the movement of the wire guide described above will be described in detail. Figure 5 (a).

(A) is an explanatory diagram showing an example of a specific method for determining the turning center 0 necessary for turning the wire rod guide 2' as shown in FIG. This shows the case where the line is composed of two circular arcs with opposite directions.
The shape of the lines also tends to be continuous with smooth curves. ]
The selector guide for the wire must be precisely aligned with the path line for the wire to pass through. As shown in FIG. 5(a), in order to accurately rotate the wire rod inlet A and outlet B to the changed entrance and to the position B', the turning center of the wire rod guide 2' must be moved to the entrance of the wire rod guide 2'. The perpendicular bisector 9 of chord 7 created by connecting exit B, and the chord 8 created by connecting the changed entrance A' and exit B'
It is sufficient to take the intersection point with the perpendicular bisector 10 of . As a special case of Fig. 5(a), Fig. 5(a) shows a case where the wire passing line is straight.In this case, the rotation center O of the wire guide is set between the inlet A and the outlet It is best to take it at equal points.

FIG. 6 is a side view showing an example of the structure of the wire rod selector guide of the present invention. The wire rod guide tubes 1° are mounted in the same direction via the guide tube mounting seat 11 on the swivel base 12 having the pivot axis 12' at the pivot center position determined in the manner described above. The swivel base 12 has a drive motor 14 attached to a pedestal 15. The worm speed reducer 13 allows the robot to rotate in the required forward and reverse directions, and.

The guide's path line is fixed in alignment with the wire's path line.

(Effects of the Invention) The wire rod selector guide of the present invention having the above-mentioned functions can easily perform switching when the direction of movement of the wire rod is reversed with just one force.

There is no problem of the wire blowing out due to the tip of the wire hitting the guide, and the wire manufacturing technology has been improved.

It is now possible to accommodate many variations due to diversification, and the effects are significant.

(Example) Next, an example of application of the wire rod selector guide according to the present invention to a rolling line will be described with reference to FIG. FIG. 7 (January) shows a case in which the present invention is applied as a selector guide 17 of an intermediate storage device 18 installed between a row of rough rolling mills 3 and a row of intermediate rolling mills 4 for wire rods.

This example is a layout example when attempting to reduce the number of expensive rough rolling mill rows by supplying wire strips from the rough rolling mill row in the second row (1u) EE rolling and subsequent lines. is 1
This layout configuration is also made possible by the present invention.

Figure 7 (portion L' (c) is an example of a variation of (a)), and Figure 7 (b) shows an intermediate material storage device installed between intermediate rolling mill row 4 and finishing rolling mill row 5. Example of application to 18, 7th
FIG. An example in which the present invention is applied to both finishing mill rows 5 is shown.

In the above embodiment, the wire rod selector guide according to the present invention is applied to an intermediate material storage device, but the wire rod selector guide according to the present invention can be used not only in an intermediate material storage device but also in an intermediate heat treatment device, etc. Therefore, it can be applied to a pickling device or a relay part with a cold working machine, and its range of use is wide. of course,
Due to its characteristics, this device can also be applied to non-metallic fields regardless of the gold bending system.
