Abstract

PURPOSE:To manufacture of a saw tough, sharp and durable, with the use of compound materials. CONSTITUTION:Carbon hard steel plates 2 for blades are superposed on both surfaces of a soft iron plate 1, leaving both end parts thereof left corresponding to cutting blades. Cutting carbon hard steel plates 3 which are harder than the hard steel plates 2 are superposed to the left parts of the soft iron plate 1. Covering carbon hard steel plates 4 are covered and superposed on both surfaces of the above-mentioned superposed material. Both end faces of the superposed material are connected with welded members 5 so that a compound material is formed. The compound material is made into a saw having cutting blades 6 by a conventional method having the steps of shaping, quenching, sharpening, etc. The saw is completely formed by removing the above-mentioned covering carbon hard steel plates 4 in the step of grinding or the like.

Description

[Detailed description of the invention] The present invention uses %-gold material to make it strong and have a sharp cut.

The details are as follows.

The - direction indicates the cutting edge of a double-edged saw, or in the case of a single-edged saw, it is convenient to cut the central part of the saw material (k<b).

Conventionally, for mating material 1: There was a one-off decision to use a convenient saw, and it was possible to reduce costs, but if a material with a stiffness was used, the board would break due to warping when inserted into the bladder. Because of this, it is difficult to use materials that are too expensive to cut, and it is necessary to use a saw that cannot cut.Composite materials such as QJ and Confucian materials are also used for soft iron plates and soft iron plates. Nikyo-kV is a single-axis type and 1
For this reason, composite members and arrow members may become thicker or sag immediately, resulting in a 11% increase in durability! There was a drawback that it could not be used.

The superposition has solved these drawbacks and is strong, sharp, and durable. This is the only 1kL saw that can be used, and having accomplished the above-mentioned method, it has the following features.

1 Akira, the deceiver, committed the robbery of the blade plate to the soft iron plate mouth J, as shown in gi11-Masaka No. 5-.
1 and 3) were used, and the IR volume for the blade & (2) was better than the 1 & (2) for the cutting blade.
Since the cutting blade (67) is electrically charged to a certain level, it becomes a saw that cuts well.

In this case, since the soft iron & .

2 Also, in this case, as shown in Section 2, υ is the cutting sword (center of 67ki) when it was formed as m Because it is located at T, it does not become a soft iron plate mouth) or a bonneron corridor when cutting.
This will prevent the sharpness from decreasing. Ii) and kIkThV-imitating charcoal-thin plate (3) for cutting blades (
Shake it with 4 steps, test one thin noodle with melted thin noodle material, and use the composite material (gradient vml heat, roll EE, etc.), so there will be no outside air coming in from the outside. 1. Shinkin when trying to bond with creases - Soft #ic huan (1), blade (2), cut-

Since it is possible to reach t'- and the saw (C) &-, the Iris III member a@- does not exist, so it also becomes m-, which is durable.◇ 4. charcoal dumplings
Depending on the cutting blade (61)
In its-Pengjing (4), the carbon steel plate for the cutting blade (37V) is set so that it is not cooled as a proverb and is slowly cooled. To eliminate distortion and prevent warping, it is therefore possible to use a material with a high straightness Vt* on the cutting edge of the Ni vertical bulk 411km plate (3), and that is all. A well-placed saw (C) V k will be provided e Rumored 5 This person's wrinkles 41! After sharpening the mausoleum board (4), the sharpening stone is removed until the surface is exposed, so there is no harm to one's body, and one cannot spin a sharp song.

6 In the case of this stomach-I&/pressure, the composite material (because the arrangement of the seasonal Ogodake layer members is symmetrical) material board ( It becomes easy to make the cut, and there is no need to straighten the material plate (b), so it becomes even easier to make and do the same thing.
