Abstract

PURPOSE:To enable carving to be easily effectively carried out especially when a drawing pattern of a leather product is treated by a method wherein a pyramid shaped chisel consisting of four sides and four ridgelines is formed of a hard material and besides, respective aperture angles of a side end, a lower end, and the side end to the lower end at a tip part are respectively specified. CONSTITUTION:A chisel is formed of a hard material of steel, cemented carbide, or ceramics, etc. Then, dimensions and angles of a four side pyramid shape at a tip part 14 of the chisel are constructed as follows. Tlhat is, in a plan at a bladed part of the chisel, a side edge blade aperture angle 7 as given in A-A' sectional part 41 is set to 90+ or -20 deg.. Further, a lower end blade aperture angle 8 as given in B-B' sectional part 42 is also set to 90+ or -20 deg.. Furthermore, a side edge blade to lower end blade aperture angle 9 is also set to 90+ or -20 deg.. Thereby especially when a drawing pattern of a leather product is treated, thrust of a wire drawing start point is improved, and conversion of a wire drawing direction is made free. Besides, a carved seal which is deep in carving will be enabled to be easily effectively carried out.

Description of the Related Art As similar and approximate tools, there are mason chisel for stone, carpenter chisel for wood, punch cone for metal, etc .; It is not suitable for carving, and its cutting edge as a processing tool is limited to a conical shape or a single-edged shape.
There are also tools such as modelers, shape punches, groovers, needles and cones for leather processing; the blade tips are not the same as the invention of the present invention because they are not for cutting pictorial patterns composed of continuous curve figures. It has a shape. As the wire drawing blade for directly processing the leather, which is directly related to the present invention,
There is a double-sided double-edged blade whose side wall surface remains flat. However, the following difficulties have been pointed out. In other words, because the side wall surface is flat and the blade is not sharpened; the biting at the drawing start point is poor and the initial positioning is difficult, and the blade edge opening angle is about 60 ° and it seems easy to engrave at first glance, Extra pressure is required, and the flatness of the surface of the plate material at the starting point is lost, resulting in damage to the cortex and image quality. It is difficult to change the direction of the lines, and it is not possible to cut delicate and elegant pictorial patterns. ， Because the push-open angle is small, only shallow marking is possible; there are many drawbacks.

となって，経済的に有利となるからである。The dimensions and angles of the tetrahedral pyramid shape of the tip portion 14 which is preferable as the engraving blade according to the present invention will be described below. The side edge blade opening angle 7 is 90 ± 20 °, more preferably 9 ± 10 °; if it is too small, it is difficult to push down and push up and the depth of carving cannot be obtained. Only a rough pattern can be obtained, and the pinpoint marking is also sweet; neither is preferable. The lower edge opening angle 8 is also preferably 90 ± 20 °, more preferably 90 ± 10 ° for the same reason. Side edge blade-bottom edge blade opening angle 9 is 90
A range of ± 20 ° is preferable. Furthermore, 90 ° is more preferable. The reason for being nearly right is that the finishing of the cutting edge becomes easy, which is economically advantageous.

業を高能率で行うことが出来る。In the conventional case, the side wall surface 6 is flat and there is no blade, so that the cutting of the blade is bad, but since the tip portion 14 of the engraving blade of the present invention has a pyramidal shape with four sides and four ridges; The starting point is easy to position, the blade bites well, pinpoint marking is possible, line drawing can be started smoothly, and fine lines with a small curvature can be cut freely in any direction. The work of the sharp edge makes it possible to perform work with high efficiency.
