Description

Correction system for the abnormally twisted metal plate

The present invention relates to a device for flattening the torsion of long metal plates cut to produce standard metal plates.

Small metal plates used in the manufacture of various machine parts or tools cut a large steel plate in a longitudinal direction in a constant direction, and then evenly cut the upper and lower surfaces of the cut long plate as in Patent Application No. 10-2012-21900 of the present inventors. Grind and finish. The trimmed plates are cut into small unit pieces of the required length to produce standard metal plates.

As the large metal sheet is cut in such a manner as cutting with a saw blade or melt cutting to have a constant width, the cutting part receives strong heat at the moment of cutting. This heat causes heat deformation with respect to the iron plate, resulting in irregular deformation of the finally cut long plate.

The relatively uniform deformation of such deformed plates can be balanced through the forming machine of the present patent application No. 10-2012-6788.

However, when the state of deformation is in a twisted shape, since the torsion itself is atypical, it is possible to calibrate one plate several times when using the forming machine of the present invention, but it takes much time for calibration. Moreover, if the degree of torsion is out of a certain range, it is often not corrected even after several corrective actions through the forming machine, and these products are disposed of and are a factor of great resource waste and cost increase.

The present invention is to provide a torsional calibration device of a long plate for the manufacture of a standard metal plate capable of correcting a long torsional metal plate of severe torsion in one calibration operation.

The present invention has developed a torsion correction device that can fix the torsion with a single corrective action by fixing the beginning of the torsion and correcting at the end of the torsion in correcting the plate twisted in different directions while being extended long .

Claim 1 of the present invention by holding the twisted metal plate at the side fixing portion at the same time to fix and then to level the metal plate by the calibration reference point fixing and correction unit.

It is about.

In the present invention, the left end fixing part and the right end fixing part are symmetrical with each other, and fix the metal plate P that is deformed from both sides.

More specifically, as shown in Figs. 1 and 2, the side end fixing parts are disposed on both left and right sides of the central calibration part and the standard base part so as to face each other.

More specifically, the left end fixing portion and the right end fixing portion form protrusions 11a on both sides of the sliding support 11, and the sliding grooves 10b having a structure corresponding to the protrusions are provided on the slider 10 so that the protrusions and Assemble to engage the groove and slide.

A tab hole 10d was fixed to the upper end of the slider 10 so that the tab hole 10d was formed to be screwable on the outer circumferential surface of the adjustment handle 12. The tab plate 10c having the tab hole is fixed to the upper end of the sliding support 11, and the adjustment handle 13 is fastened to the tab hole formed in the tab plate. And the lower end of the adjustment handle is fastened to the stud hole (10a) formed on the upper end of the slider (10). When the adjustment handle is rotated in this configuration, only the slider is lifted and lowered while the sliding support is fixed. The lower end of the slider is strongly buried with the left end and the right end of the plate to be corrected by means of a pair of fixed bytes 10a, thereby enabling torsional correction work.

The lower end of the sliding support 11 is supported by the base 15 so as to support the lower end and the front end of the actuating rod 16 of the hydraulic cylinder 16 and the outer base 15a, and both sides of the standard base (D) In this configuration, it is possible to move forward or backward toward the center. This configuration allows for strong and stable gripping even when the metal plates are slightly different in size.

As described above, the side end fixing portion is configured to be forward and backward by fastening the operating rod to the outer base 15a installed at the bottom, and the right or left side fixing portion is configured to simultaneously rotate and move together with the simple forward and reverse movement. It was.

In more detail, as shown in FIG. 4, instead of the operating rod 16, the rotating shaft 41 of the straightening unit capable of simultaneously rotating forward and backward is fastened to the base.

In the present invention, for convenience of explanation, the rotary shaft is installed on the left end fixing part (A), but this type of installation may be equally installed on the right fixing part according to the structure of the site to be installed and the needs of the consumer.

The calibration reference point fixing part of the present invention is to install the left and right moving guiding part 21 on the lower base 100 of the torsional calibration device and at the same time installs the forward and backward guiding part 23 via the horizontal moving guider and the vertical angle 22. ,

When the start point of the torsion is determined, the calibration reference point fixing unit as shown by the arrow in Fig. 8 advances the reference byte 24 to ask the torsion start position of the metal plate. In this fixed state, the torsion correction operation of the required degree is performed by rotating the rotary shaft 41 of the correction unit installed on the left end fixing part.

Conventionally, without the calibration reference point fixation, only the two sides of the metal plate are fixed and corrected, and the original twist is restored by the elasticity after the correction. Even in the torsional form, the plate was leveled to recycle waste plates.

In the present invention, as shown in Fig. 6, the standard base is provided with a surface plate 31 between the left end fixing part and the right end fixing part installed on both sides,

The above-described surface plate was formed to guide the guide groove 33 which is allowed to go out of the seating bar 32, so that the seating bar is raised and lowered by the entry and exit operation of the operation rod of the lower pneumatic cylinder was configured to seat the plate (P).

The surface of the standard base is always at a constant plane, and when placed here on a plate that needs to be calibrated, the direction and degree of torsion can be measured.

And with the seat bar in place, the heavy plate can be easily fixed without the use of manpower.

In the present invention, as shown in FIG. 4, the straightening portion fastens the shaft end portion 41a of the rotating shaft 41 to the outer base 15a of the left end fixing portion A so that the entire left end fixing portion is rotatable by rotation of the rotating shaft. Install it,

As shown in the calibration unit, it is possible to secure the accuracy of the torsion correction by installing a separate angle measuring device 55 to match the correct calibration angle according to the degree of torsion measured on the surface plate. The same correction part is installed in the right side fixing unit opposite to the left side fixing unit. Furthermore, it is also possible to install the calibration part on both the left and right fixing parts in the same way, and at the same time, by simultaneously twisting the metal plate from the left and right, it is possible to perform the calibration at the same time.

The operational relationship of the present invention according to the structural features described above will be described with reference to FIG.

As shown in FIG. 7, when the right and left sides are shifted from each other to produce a twisted metal plate P, the metal plate is disposed on the surface plate 31 of the present invention. When placed on the surface plate, the degree of twisting and the twisting direction of the metal plate are visually identified or measured using a separate measuring device.

In the state where the metal plate is placed on the surface plate, the pneumatic cylinder installed at the bottom of the surface plate is operated, and the seating bar 32 lifts the metal plate, and arranges both ends at the left end fixing part and the right end fixing part installed at the left and right sides.

In this arrangement, the adjustment handles of the left end fixing part and the right end fixing part are properly adjusted to fix both ends of the metal plate to be horizontal to each other.

When the fixing of left and right is completed, fix the part where the torsion starts by the calibration reference point fixing part installed in the center. The horizontal position is set to the position where the torsion starts along the left and right movement guiding part 21 on the lower base 100. The reference byte is then advanced toward the metal plate as indicated by arrow K.
