でき難いという難点を有している。
In conventional saws with a back metal, the back metal is directly fitted to the back of the saw blade, but this fitting requires that the thickness of the saw blade and the groove width of the groove in the back metal are equal. something is required. In other words, if the thickness of the saw blade is thicker than the groove width of the groove in the back metal, it will be difficult to fit them together, and if you try to force the back metal to fit into the back of the saw blade, the back metal will not engage. The back part of the saw blade expands, and the internal stress generated by this expansion causes the entire saw blade to lose its balance and become distorted. When used, the workpiece will be cut in a curved manner, and if the thickness of the saw blade is thinner than the groove width, there will be a gap between the two, causing the saw blade to wobble within the backrest, making it difficult to use. . For this reason, normally, the groove width of the groove on the back metal is made larger than the thickness of the saw blade, and the back of the saw is inserted into the groove, and the back metal is struck or pressed from the front and back sides. The groove width is narrowed to hold the back of the saw blade, but the dimensional accuracy of the steel plate itself is not good, and the processing accuracy of the steel plate used for the saw blade and back plate is low. The total error is quite large when the dimensional errors caused by the dimensional errors are added, and if the saw blade is clamped to the back plate by the machine, many defective products will be produced for the reasons mentioned above. It has the disadvantage that it cannot be done by just anyone, as it is assembled by skilled craftsmen while considering the condition of each piece, and therefore, it is difficult to mass produce.

In order to solve the above-mentioned problems, the present invention has a back plate 3 having an inverted U-shaped cross section on the back part 2 of the saw blade 1. A buffer body 4 is provided between the inner surface 3 and the inner surface 3 of 1 , and the buffer body 4 may be one piece, or each thin plate may peel off a plurality of thin plates 4 1 , 4 2 , 4 3 , 4 4 . A laminate plate may also be used, and the above-mentioned buffer body 4 may also be used.
may be engaged with the back plate while simply stacked on the back part of the saw blade 1, or it may be attached to the back part 2 of the saw blade 1 in advance and then the back part 2 of the saw blade 1 is inserted into the groove of the back plate 3. 3 It is also possible to engage within 1 .
本案は上記の構成であつて次のように作用をす

ければならない。
The present proposal has the above structure and operates as follows. Conventional saws with a backrest are made by directly fitting a mild steel backing with an inverted U-shaped cross section to the back of a hard steel saw blade, so any distortion in the backing is immediately transferred to the saw blade. It distorts the saw blade, making it difficult to use the saw.The saw blade is very hard, so if you apply too much distortion, it may break. Particularly when the saw blade is extremely thin (0.2 mm to 0.5 mm), such as a conductive saw, there is a risk of damage even if the blade is subjected to even a small amount of distortion, so distortion must be avoided.
ところが現実は、鋸身や背金となる鋼板の板厚

１に加算されないようにしたものであり、逆に鋸
身が歪んで歪修整をした場合、鋸身の歪が緩衝体
４に吸収され背金３に歪修整を妨げられることな
く背金３が付いたまゝ歪修整ができる。 However, in reality, there is a large degree of allowable error in the thickness of the steel plates that make up the saw blade and back metal, and the machining accuracy of the saw blade and back metal is not very good. It is difficult to engage the back part 2 of the saw blade 1 accurately and reliably, which often results in damage to the saw blade.
A buffer body 4 is provided between the inner surface 3 2 of the groove 3 1 of the back plate 3, and when the back plate 3 clamps the back part 2 of the saw blade 1, the strain force of the back plate 3 is absorbed by the buffer body 4. This is to prevent the distortion of the back plate 3 from being added to the saw blade 1. Conversely, when the saw blade is distorted and the distortion is corrected, the distortion of the saw blade is absorbed by the buffer 4 and the distortion is corrected in the back plate 3. Distortion can be corrected with the back plate 3 attached without being obstructed.

係合するものであるから鋸身１と背金３との係合
が正確且確実になし得るものである。 Moreover, the buffer body 4 consists of thin plates 4 1 , 4 2 , 4 3 , 4 4 .
...However, if each thin plate is made of a laminated plate that can be peeled off, there will be a mismatch between the groove width b of the groove 3 1 of the back plate 3 and the thickness of the saw blade 1. For example, the thickness of the saw blade side will be If it is thicker than the groove width b, the thin plate can be peeled off and adjusted to the optimal thickness for engagement, allowing for easy clamping. Furthermore, the buffer body 4 is attached to the back 2 of the saw blade 1 in advance.
If the shock absorber 4 is bonded with adhesive or the like and then engaged with the back metal 3, the cushioning body 4 can be smoothly engaged without damaging it. When inserting the buffer body 4 bent into an inverted U-shape into the inside of the saw blade 1 and then trying to fit the back part 2 of the saw blade 1, it is quite difficult to insert the buffer body 4 into the concave groove 31 of the back plate 3. It is accompanied by a concave groove 3 1
Accurate and reliable insertion to the innermost part of the saw blade cannot be expected, and this will cause problems in the subsequent engagement of the back part 2 of the saw blade 1 with the back metal 3. However, in this case, the saw blade 1 with the buffer 4 installed on the back part 2 in advance is engaged with the back metal 3, so the engagement between the saw blade 1 and the back metal 3 can be achieved accurately and reliably. .

しているもので、まことに面倒なものであつた。 If this outer design is used as a replaceable blade saw and the saw blade 1 is detachable from the back plate 3, when replacing the saw blade 1,
Since the back metal of this type of saw with a back metal often becomes distorted after repeated use, it is not recommended to directly engage the saw blade 1 with the groove 31 of the back metal 3 without using the buffer 4. Saw blade 1 that engages with gold 3 unless the distortion is corrected
will suddenly become distorted. However, it is impossible to correct the back plate 3 due to its structure, and in the past, distortion correction had to be done by hand by trained distortion correction craftsmen to a barely usable condition, which was extremely troublesome.

Even if the buffer body 4 absorbs the strain on the back plate 3, the saw blade 1
The saw can be used smoothly and accurate cuts can be made without adversely affecting the machine.

FIG. 3 is a front view of the saw blade with a buffer attached to the back, FIG. 4 is a sectional view illustrating the engagement relationship between the back plate and the saw blade, and FIG. 5 is a sectional view taken along the - line. Figure 6 is a - line cross-sectional view, and 1 has a plate thickness of 0.2 mm.
It is an extremely thin heat-treated steel saw blade of ~0.5 mm, and the cross section is inverted U-shaped and the groove width b is 0.3 mm.
It is a back metal having a concave groove 31 of about 0.6 mm, and 4 is 0.1 mm 0.2 made of soft and elastic metal foil such as aluminum or copper, paper, plastic film, etc.
This is a buffer with a size of about mm and is provided between the back part 2 of the saw blade 1 and the back metal 3. This buffer 4 may be in the form of a single plate, or it may be a laminate made of two to four extremely thin plates, for example, about 0.01 mm, each of which can be peeled off. In case,
The back part 2 of the saw blade 1 can be engaged with the back metal 3 in an optimal state. That is, the thickness c of the back part 2 on which the buffer body 4 of the laminated plate is attached is made considerably thicker than the thickness a of the saw blade 1, and when the back part 2 is engaged with the back part 3, the concave groove 31 of the back part 3 is made considerably thicker. By peeling off and using an ultra-thin plate-shaped material so that the thickness corresponds to the groove width b, the engagement between the back plate 3 and the saw blade 1 can be properly achieved, and when replacing the saw blade 1, it is possible to By adjusting the thickness c of the back without changing the groove width of the back metal like a saw, it is possible to achieve proper engagement and eliminate the distortion caused by touching the back metal 3, which is one of the causes of distortion in the back metal 3. The concave groove 3 of the back plate 3 will eliminate the inconvenience that may occur.
It is most suitable for a saw blade for a replaceable blade used in a saw with a back metal of the replaceable blade type where the groove width b of 1 tends to change and become irregular during use. The cushioning body 4 may be made of the same material, but in order to ensure smooth insertion of the back plate 3 into the groove 31 , it may be made of a material with a slippery surface, such as gold foil or paper, and a soft cushion inside. For example, a composite material made of different materials such as plastic film may be used. Furthermore, if the buffer body 4 is attached in advance to the back part 2 of the saw blade 1, engagement with the back metal 3 is facilitated. A saw with a back metal of the present invention is constructed by attaching a buffer body 4 to the back part 2 of such a saw blade 1 and engaging the back metal 3 onto the buffer body 4.

As described in detail above, the saw with a back bar according to the present invention has a buffer 4 between the back part 2 of the saw blade 1 and the back bar 3 that engages with the back part 2 of the saw blade 1.
By providing this, by engaging the back plate 3 with the saw blade 1, the clamping force that clamps the saw blade 1 eliminates the strain imbalance of the saw blade 1 caused by the elongation of the clamping part, and also eliminates the strain imbalance that occurs during use. There is no distortion of the saw blade 1 due to distortion of the back metal 3, and even if the saw blade 1 itself begins to become distorted during use, the back metal is Unlike the case where the saw blade is fixed and there is no place for the strain to escape, causing the saw blade to become distorted, the strain generated in the saw blade 1 escapes to the buffer 4 and is absorbed, preventing the saw blade 1 from being distorted. It is a thing,
The buffer body 4 also includes a plurality of thin plates 4 1 , 4 2 , 4 3 , 4 4 .
By making it a laminated plate, the thickness of the part of the saw blade 1 that engages with the back metal 3 can be adjusted by peeling off the thin plate, making it impossible to engage the back metal 3 and the saw blade 1. This allows for the best possible engagement without any friction. Furthermore, if the buffer body 4 is made of a laminated plate of thin plates, each of which can be peeled off, the thickness c of the back of the saw blade 1, which is the sum of the thickness a of the saw blade 1 and the thickness of the buffer body 4, can be changed. , it is possible to respond to changes in the groove width b of the concave groove 3 1 of the back metal 3 with which the saw blade 1 is to be engaged, and if the thickness c of the back part is larger than the groove width b, the thickness of the buffer body 4 can be changed. This invention has the advantage of being thin and capable of achieving optimal engagement, and of achieving optimal engagement between the saw blade 1 and the back metal 3.
