Description

  The present invention relates to a cutting bar having cuts made on the upper and lower surfaces and both side surfaces of a flat rectangular cutting bar.

Conventionally, in order to prevent non-uniform expansion when kerchief is baked, a technique is known in which a cross-shaped cut is made on the upper surface or the upper and lower surfaces, or a cut parallel to the upper surface is made on the side surface.
Patent No. 3620045 Japanese Patent No. 3817255 Japanese Patent No. 4111382

  Conventionally, there has been a proposal of a cutting rod in which a cross cut is made on the upper and lower surfaces of the cutting rod, and the depth is cut to the long side surface to make a cutting of 30 to 40% of the thickness of the rod (Patent Document 1). In addition, there is a proposal of a scissors in which cuts having different front and rear depths are made on the peripheral side surface of the housing (Patent Document 2).

Furthermore, there is a proposal of a scissors that is provided with an annular cut portion on the side surface of the housing or a cut portion on opposite two side surfaces (Patent Document 3).
In the above-mentioned conventional invention, it is aimed to achieve uniform expansion when baked by deepening the cuts on the side surfaces or by making the cuts in an annular shape. In the present invention, not only the upper and lower surfaces are cut, but the side surface is not an annular cut or deepened, and the cuts are provided obliquely and crossed to achieve equal expansion of each part. is there.

  Originally, chopped soot is obtained by rolling, so the quality is uniform, but it tends to cause uneven expansion due to uneven distribution of bubbles, uneven viscosity, uneven heat transfer, etc. Become. In order to prevent this, as in the above-described conventional invention, the incision is provided in an annular shape or the incision depth is devised, but it has been difficult to achieve uniform expansion.

  In the prior art, in order to provide the cut in an annular shape, the number of processing steps is increased by one step, and in order to increase the depth of cut, there is a problem in processing such as special consideration at the time of cutting. . Further, due to the homogeneity of the soot and the non-uniformity of the heat conduction during firing, there is a possibility that non-uniform expansion may occur even with the conventional notches.

  This invention is a case where cuts are made on the upper and lower surfaces and both side surfaces of the cutting rivet, and the cuts on both side surfaces are prone to uneven expansion due to rolling, firing or other causes by providing oblique cuts. Even so, the steam could easily escape from each notch, and as a result, it was able to expect uniform expansion and a beautiful appearance.

  That is, according to the present invention, in a scissor made by cutting into the upper and lower surfaces of the flat rectangular frame and the two opposite side surfaces, a cut is made parallel to the side surface at the center of the upper and lower surfaces, and the notches on the two side surfaces are inclined. It is a cutting rod characterized by being cut so as to intersect.

  In the above description, the cutting rod has a flat rectangular shape, but a square shape has the same effect, and thus has a flat rectangular shape.

  In addition, in a cutting rod having cuts in the upper and lower surfaces of the flat rectangular housing and the two opposite side surfaces, a cut is made in the center of the upper and lower surfaces in parallel with the side surfaces, and oblique cuts are crossed over the two side surfaces. In addition, the upper and lower ends of the oblique notch facing the upper and lower surfaces are made to not reach the upper surface or the lower surface, and the upper and lower center cuts are cross-shaped. The two side surfaces are long side surfaces, the long side cuts are inclined at 10 to 80 degrees with respect to the upper or lower surface, and the side cuts are 1.0 mm to 5.0 mm deep. It is.

  As described above, the oblique cut angle in the present invention is 10 to 80 degrees with respect to the upper surface or the lower surface, and preferably 20 to 50 degrees. When the angle is 10 degrees or less, if each oblique line is set at a predetermined interval (for example, 5 mm to 10 mm), not only the number of oblique lines provided on the side surface of the cutting bar is reduced, but also the number of intersection points is reduced, resulting in uneven expansion. Is likely to occur. On the other hand, if the angle is 80 degrees or more, the number of cuts increases at the same pitch, but the cuts are not preferable because the cuts prevent the expansion of the ridges, making it difficult for heated air to escape and causing uneven expansion.

  Next, the depth of the cut may be 1.0 mm to 5.0 mm as described above, and the side surface of the cutting bar is the cut surface (the surface cut by the cutting blade), and the same quality as the inside of the bar (surface hardening, etc.) Therefore, the expansion force is uniform and the average expansion is facilitated. In addition, since the effect does not change even if the cuts are provided on the four side surfaces, the two side surfaces are provided.

  According to the present invention, the upper and lower surfaces of the casing are provided with cuts, and the diagonal cuts are provided on the two side surfaces, so that when the bowl is baked, it expands evenly to prevent partial abnormal expansion and evenly. There is an effect that can expand.

  In addition, since the cut is relatively shallow and it is sufficient to provide it only on the opposite two side surfaces (in the case of a rectangular shape, it is usually provided on the long side surface), the processing is simple and the product is manufactured. Since there is no need to increase the number of processes and high-speed machining can be performed, there are various effects such as improvement in efficiency.

  The present invention is a cutting rod having a cut in the upper and lower surfaces and both long side surfaces of a flat rectangular frame, and a cut in parallel to the side surface is made in the center of the upper and lower surfaces, and oblique cuts are made in both long side surfaces. The crossing is made so that a long cut is provided with an intersection. The depth of the cut was set to 1.0 mm to 5.0 mm.

  In the above description, the planar rectangular cutting rod has been described. However, in the case of a planar square, it is possible to achieve equalization of expansion by providing it on any pair of opposing side surfaces (front and rear side surfaces or left and right side surfaces).

  Therefore, in the case of a rectangular cutting flaw, even if a cut is made on the short side, there is no great difference in effect. This is because the difference in length between the long side surface and the opposite side surface is about 20 mm (60 mm × 40 mm), both are cut skin, and the resistance to expansion is almost the same. This is because there is no big difference. However, in the case of a rectangular cutting bar, it is preferable to provide a cut on the long side surface because the difference in expansion resistance from the inside can be reduced.

  The depth of the cut varies depending on the state of the wrinkles, but is preferably 2 mm to 4 mm. For example, when the depth is less than 1 mm, the degree of steam escape tends to be uneven, and even when the depth exceeds 5 mm, there is no great difference in the degree of steam escape. Further, when the depth reaches 4 mm, a microcrack is formed at the tip of the cut, and the vapor escape condition may be improved.

  An embodiment of the present invention will be described with reference to FIG. 1. Cross cuts 4 and 4 are provided on the upper and lower surfaces of the housing 1, and cuts 2a and 2b having an angle of 30 degrees are provided on the long side surfaces 1a and 1b. The cutting rod 5 of the invention was configured. The interval (vertical direction) L between adjacent cuts is about 6 mm. However, it is not necessary to limit the dimension of L.

  In the above embodiment, there are three or more intersections 3 and 3 on one incision line, but the objective (equalization of expansion) can be sufficiently achieved even with three or less. Since there is no practical limitation to the number of intersections, it is considered that one or two per cut is sufficient.

  When the cut rice cake of the above embodiment is baked in a normal manner, it expands almost evenly as shown in FIG.

  Even if a cross-shaped cut 4 is made at the center of the upper surface and the lower surface of the housing and a cut 7 parallel to the upper surface is made at the center of the side surface, it may swell evenly. Yes (FIG. 1 (d)). In short, in the case of the above-described embodiment (FIG. 1C), it is highly probable that the bulge is equally beautiful, but in the case of the conventional example (FIG. 1D), there are many cases of uneven bulging. That is.

  A large number of rhombuses can be formed by cutting the both side surfaces of the above embodiment, but the shape of the rhombus varies depending on the angle of cut, but there is no difference due to this shape.

  Referring to FIG. 2, another embodiment of the present invention will be described. Cross cuts 4 and 4 are provided on the upper and lower surfaces of the casing 1, and cuts 2a and 2b having an angle of 30 degrees are provided on the long side surfaces 1a and 1b. The upper and lower ends and the upper and lower surfaces of the cuts 2a and 2b are spaced apart from each other by an interval H. The reason for providing this distance H is that if the notches 2a and 2b are made to intersect with the upper surface or the lower surface, the wrinkles at the intersecting portions (points c and d) may be slightly broken.

  Even if the notches 2a and 2b do not reach the upper surface 1c or the lower surface 1d, the effect of extracting steam is not changed. In FIG. 2B, H is 1 mm to 3 mm, usually about 2 mm.

  The difference between the first embodiment and the second embodiment is whether or not the notch reaches the upper surface 1c or the lower surface 1d, and the others are the same. And In Example 2, the oblique cut did not reach the upper surface and the lower surface, so there was no possibility of chipping from the cut portion.

(A) The perspective view of the Example of this invention, (b) The same front view, (c) The reduction | decrease perspective view similarly fired, (d) The perspective view which the same conventional firewood fired. (A) The perspective view of another Example similarly, (b) Similarly a front view.
