Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to roller straightening equipment in a section steel manufacturing factory, and in particular, the invention relates to roller straightening equipment for a shape steel manufacturing factory, and in particular, a scalene It is suitable as straightening equipment for thick mountain shaped steel (commonly known as invert).

(Prior art) The above-mentioned scalene angle shape steel is made into a channel steel (cross-sectional shape or square shape) by hot rolling, and then cut in half by gas cutting etc. to make two channels from one channel steel. However, when the material is cut in half, the internal stress generated during rolling and the stress during cutting are released, causing bends and warps, so it must be straightened.

(Problem that the invention attempts to solve) However, the two inverts with the web of channel steel cut are placed in opposite positions (〓〓) with the webs facing each other, so they cannot be used as they are. Due to the posture, it cannot be processed with one roller straightening machine, and two
There was no need for a stand roller straightener, that is, two lines.

As a result, equipment costs increased and it was necessary to deploy a large number of workers.

(Purpose of the invention) The present invention aims to solve the above-mentioned conventional difficulties and provide an efficient angle steel straightening equipment that can process four inverts supplied from two parallel transport lines in one line. It is.

(Means for solving problems) The present invention will be explained in detail below with reference to the drawings.

FIG. 1 is a plan view showing the layout of a place C for cutting channel steel in half, a transfer bed (skid rail) S, a roller table R, and a roller straightening machine L. One (2) half-cut angle steel (invert) is transported from each floor S to
A turner T is provided that supports and rotates 180 degrees.

Each arrow indicates the direction of transport from the half cutting place C to the straightening machine L.

As shown in FIG. 5, one embodiment of the turner T rotates on an annular track 3 provided on a circular (annular) bracket 7 as shown in the ceiling 2 of a support frame consisting of a support column 1 and a ceiling 2. It consists of a trolley 4 and a hanging tool 5.

The trolley 4 is provided with a rotational drive mechanism (not shown). 6 is a rotation center axis.

The hanging device 5 has a plurality of hooks 10 provided on a beam 9 provided via a support device 8 provided on the truck 4.

The support 8 is equipped with a lifting device, and has a hook 10.
is movable in the vertical direction at a position between each roller of the roller table R.

(Function) Under such a configuration, the angle irons 11a and 11b, 11c and 11d cut in half at the half-cutting location C are as follows:
As shown in FIG. 4A, it is transferred to both sides of the roller table R as shown.

First, the hook 10 is lowered and prepared as shown in FIG. 4A, and then, as shown in FIG. 4B, the front angle iron 11b is transferred from the transfer bed S by a dog (transfer claw, not shown). Place it on roller table R.

Next, as shown in FIG. 4C, the hook 10 is raised to standby, and as shown in FIG. 4D, the other angle iron 11a is raised.
is placed on the roller table R and sent to the straightening machine first. Then rotate hook 10 180 degrees and
After changing the direction of 1b, the hook 10 is lowered as shown in FIG. 4E, and the hook 10 is placed on the roller table R and sent out.

This operation is performed using the section steel 11 on the right side of the roller table R.
The same process is performed for d and 11c.

(Example) Figures 2 and 3 show embodiments other than the layout shown in Figure 1. Figure 2 shows an example in which two rows of cutting devices are provided before and after the turner T;
The figure shows an example in which one row each of cutting devices and transfer beds is provided, and implementation in this manner is also possible.

(Effects of the Invention) According to the present invention, the angle-shaped steel obtained by cutting the channel steel in half can be efficiently fed to the roller straightening machine without any stagnation. That is, according to the present invention, two rows of shaped steel 11b, 11
It is possible to change the direction of d by 180 degrees and align them in the same direction, contributing to improved productivity.
