Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cutting device for cutting a hat-shaped cross-section press product into a plurality of pieces.

[0002]

[Prior Art]

 As the body components of automobiles become larger, as shown in FIG. 9, as a replenishment part that is easy to carry, a hat-shaped cross-section press product W is press-cut at a plurality of places C1 to C4, and a plurality of parts W1 to W4 are It is divided.

[0003]

[Problems to be solved by the device]

 As shown in FIG. 10, the upper die cutting edge E for press-cutting the hat-shaped cross-section pressed product W is different from the cross-sectional shape of the hat-shaped cross-section pressed product W, so that the upper die cutting edge is There is a problem that the press product W on the E side is deformed by being pressed by the upper die cutting edge E during cutting.

An object of the present invention is to provide a press product cutting device that solves the above-mentioned conventional problems.

[0005]

[Means for Solving the Problems]

 The gist of the present invention for achieving the above object is a cutting device for cutting a hat-shaped cross-section pressed product into a plurality of pieces, and a lower cutting blade having the same shape as the inner shape of the hat-shaped cross-section. A lower die having a lower pad and a lower pad; and an upper die having the same shape as the inner shape of the hat-shaped cross-section, the upper die having a contact with the lower pad, and the upper pad having an abutment with the lower blade. It consists of an upper mold, and the lower pad is divided into left and right parts from the center, and can be expanded and contracted left and right by a spring with a stroke equivalent to the thickness of the pressed product.

[0006]

[Action]

 With the above configuration, the upper die descends, the upper pad hits the pressed product, and then the upper die cutting blade cuts the pressed product. The lower pad is pressed down by the upper die cutting edge while holding down the pressed product, allowing the deformation of the pressed product to be cut to a minimum.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 1 is a lower mold and 2 is an upper mold. The lower mold 1 is provided with a lower mold cutting blade 3 and a lower pad 4 elastically supported in the vertical direction by a spring 5. Further, the upper die 2 is provided with an upper die cutting blade 6 that is in contact with the lower die 5 and an upper pad 7 that is elastically supported in the vertical direction by a spring 8 and that is in contact with the lower die cutting blade 3 described above. ing. W is a press product having a hat-shaped cross section.

As shown in FIG. 2, the lower die cutting edge 3 and the upper die cutting edge 6 have the same shape as the inner shape of the hat-shaped cross section of the pressed product W. Further, both the lower pad 4 and the upper pad 7 have the same shape as the inner shape of the hat-shaped cross section of the pressed product W.

As shown in FIG. 5, the lower pad 4 is composed of blocks 4a and 4b which are divided into left and right parts from the center, and a base 4e elastically supported by the spring 5 at a vertical stroke S3 (see FIG. 8). It is held slidably in the left and right direction above, a spring 4c is interposed between both blocks 4a and 4b, and a stroke S1 corresponding to the plate thickness of the pressed product W is provided by a stopper 4d provided at the side end of both blocks 4a and 4b. (See FIG. 7) It is a structure that can be expanded and contracted to the left and right.

The press product W can be expanded and contracted to the left and right with a stroke equivalent to the plate thickness, and can be moved up and down. On the upper part of the lifter 2, left and right downward inclined surfaces 3a and 3b are formed, which slide the left and right pair of pressed products WR and WL on the lower mold 1 to the left and right.

Since the present invention has the structure as described above, a press product W having a hat-shaped cross-sectional shape as shown in FIG. 9 is set on the lower mold 1 and the upper mold 2 is lowered. As a result, as shown in FIG. 2, when the upper die cutting edge 6 descends to H1 before bottom dead center and the side surface of the upper die cutting edge 6 is inconsistent with the side surface of the lower die cutting edge 3, the press product W is still left. Neither the side surface nor the upper surface of the is cut.

Further, as shown in FIG. 3, when the upper die cutting edge 6 is lowered from H1 before the bottom dead center by H2, one standing wall portion of the pressed product W is cut by Δt. However, the other standing wall portion and the flat surface portion of the pressed product W are not cut.

Further, as shown in FIG. 4, when the upper die cutting blade 6 is lowered to the bottom dead center, the other standing wall portion and the flat surface portion of the pressed product W are cut, and the cutting product W is completely cut. As shown in FIGS. 7 and 8, when the upper die cutting edge 6 is lowered to the bottom dead center, the left and right blocks 4a and 4b of the lower pad 4 are reduced in a stroke corresponding to the plate thickness of the pressed product W. It The other standing wall portion of the pressed product W is pushed inward by that amount, and the other standing wall portion is cut by the upper die cutting blade 6 and the lower die cutting blade 3.

At the same time, the lower pad 4 is pushed downward by the stroke S3 via the base 4e, so that the flat surface portion of the press product W is lowered by the stroke S2, whereby the upper die cutting edge 6 and the lower die 6 are lowered. It is cut by the mold cutting blade 3.

[0015]

[Effect of the device]

 As described above, according to the present invention, a lower die having a lower cutting edge and a lower pad having the same shape as the inner shape of a hat-shaped cross-section press product, and the inner shape having the hat-shaped cross-sectional shape are the same shape. An upper die having an upper die cutting edge that is in contact with the lower pad and an upper die that is in contact with the lower die cutting edge, and the lower pad is divided into left and right from the center, and is pressed by a spring. Since it can be expanded and contracted to the left and right with a stroke equivalent to the plate thickness, it is possible to cut a plurality of parts in the pressing process with a minimum amount of deformation to provide a divided supply part.
