Abstract

PURPOSE:To perform the strain removal of the work having multi-direction strain simply and efficiently by arranging the position control machine that can control freely in the transfer stage the transfer position of a metal plate among plural roll type strain straightening machine groups. CONSTITUTION:The position control mechanism provides with the direction converting mechanism 6 composed of the two lines of small roll groups 8, 9 having individual driving system between the carry-in part 4 and carry-out part 5 which are driven by linking with the same belt 7. Regarding the position control, the relative transfer seed of the roll groups 8, 9 is set so that the direction conversion can be performed by the angle theta on the direction converting mechanism 6 by setting in advance the direction of the work 3 before and after the direction conversion on X, Y two axes. The work 3 is then passed through between the roll levelers 1, 2 at front and rear steps for performing the strain removal. In this way the strain removal of the work having multi- direction strain can be performed simply and efficiently.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to removing strain from a metal plate (hereinafter referred to as a workpiece).

Generally, roll type strain straightening machine (hereinafter referred to as roll leveler)
The bottle is made with the purpose of removing strain in a single direction from the workpiece, and therefore, the bottle that removes strain in multiple directions is made by inserting a leveler to remove strain based on the situation where strain occurs on the symmetrical workpiece. The conventional method is to determine the direction (approximately two axes) and repeat insertion by changing the insertion direction (insertion posture) along the set direction as shown in Figure 1 to completely remove distortion. It has been taken.

This conventional method has low efficiency, low workability, and is complicated, and requires some revision.

The present invention was made to eliminate the above-mentioned defects, and solves the problem simply and functionally by disposing an attitude control device between a group of a plurality of roll levelers.

The structural structure of the present invention will be explained as follows based on nine embodiments of the present invention with reference to the drawings.

As shown in Fig. 2, the main components of the tllI command of the present invention are a front roll leveler 5-(1), a rear roll leveler (2), and a posture control machine placed between them to control the posture of the workpiece. and is systematically combined with the drive system of the @ element.

The front and rear roll levelers have approximately the same structure as a conventional unidirectional roll leveler, and the attitude control machine has the following structure.

The attitude control machine has a loading section (4
) From II exit (5) and direction changer fill (6)
As shown in FIG. 2, the belt (7) is located at the bottom of the direction changer 1 (6) and connects the loading section (4) and the unloading section (5).

The direction conversion 1411 (6) is composed of two rows of small roll groups (8) and (9) each having an individual drive system.

In contrast to (8), (9) has a 4'llI construction in which the posture of the workpiece passing through the upper parts of (8) and (9) can be freely changed by setting the transport speed to M speed separately. .

Due to the above structure, when in use, the direction of the work to be inserted into the roll leveler for removing strain from a given work is set to two axes, X and Y, as shown in FIG. Next, the conveyance speed for (8) of the small roll group (9) is set so that the direction of the workpiece (3) of the θ° length workpiece shown in FIG. 3 can be changed on the direction changing mechanism. Next, work (3)
axis.

Insert it at the entrance of the front roll leveler (4), aligning it with the axis of the machine.

After passing through the roll leveler (4) in the first stage, the workpiece (3) is changed in length by θ° on the direction changing mechanism (6), and transferred to the second stage in a position where its Y axis coincides with the machine axis. It is inserted into the roll leveler (5) and a predetermined distortion is removed.

This device is capable of handling workpieces with multidirectional strains (as shown in Figure 4).
In this case, the effect was particularly great for θ°-90°, and the efficiency and workability were significantly improved.
