Abstract
The present invention improves a sawing saw that is attached to the end of a long pole 300 to easily cut branches that are located higher than the operator's key so that the blade is bent before the last part is cut off due to its own weight during cutting And moreover, to a new top structure and a molding method thereof which can be manufactured at a low cost and at a simpler speed at the time of formation and processing of a saw blade.
That is, a coupling portion 110 is formed in which one or more bolting grooves 111 are opened so as to be coupled with the pole 300, and on the upper side of the coupling portion, a curved top body A basic saw blade 130 serving as a cutting element for a wood material is formed on one side of the curved top body steel plate 120 and the basic saw blade 130 has a predetermined size A plurality of saw teeth 131 are formed in parallel at regular pitch intervals. In the structure of the saw cut only saw, the other side of the curved top body steel plate 220 at a position opposite to the basic saw blade 130 And an additional second saw blade 200, which is separate from the basic saw blade 130, is further formed.
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a saw that can be used for cutting branches having a relatively small thickness and a method of forming and processing the saw blade.
Usually, branches are an essential element in the growth of trees and fruit, but it is required to cut off early if it becomes unnecessary laughing or obstructing the growth of other faithful branches.
Meanwhile, in the conventional saw cutter, the saw for sawing wood is firmly tied or bonded to the end of the long pole 300, so that even a branch located at a high position not reaching by hand can be cut easily do.
A conventional saw cutter B for cutting a tree cut at the end of a long pole 300 is formed with an
A curved top
A
The
At this time, not only the plurality of
It is common that the width of the teeth is slightly larger than the thickness of the steel plate because the steel plates are alternately bent in the thickness direction.
However, the above-mentioned conventional saw blade (B) structure is very effective in the case of relatively thick wood having a higher support base than the resistance involved in sawing (forward and backward movement) While it is true that efficiency can be achieved,
In the case of the branch having a thin thickness and a weak support base, there is a problem in that it is difficult to perform the actual cutting only by shaking due to the resistance of the saw blade to the sawing (forward and backward movement of the saw).
That is, as described above, the conventional saw blade has not only different inclination angles formed on both sides of each of the saw blades but also has a shape in which the width of the saw teeth is slightly wider than the thickness of the steel sheet, Because of,
Cutting efficiency is very high, but when cutting saw branches with weak resistance (support base) due to high resistance to saw blade during sawing (forward and backward movement), they move only in accordance with the movement of the saw, many.
In this case, cutting can be accomplished only by sawing at a high speed which is much higher than the speed of general sawing, which makes it difficult to work for a long time.
Conventional saw blade forming and machining methods can also be applied to various kinds of high-priced equipments to form a basic saw blade, to set up different inclined blades on each tooth, to stagger each raised saw tooth, to heat treatment process and plating process, Processing and molding processes, as well as a high level of technical expertise and know-how, and a considerable cost.
Further, since the conventional saw cutter is formed only on one side of the saw body steel sheet, it can not be sawed in only one direction in which the saw blade is formed,
Therefore, if you need to cut a piece of the bottom part to prevent damage to the torn wood, cut the last part of the trunk while the branch is cut off, and turn the whole heavy and long branch cutting saw hard by 180 ° There was a problem that it was inconvenient.
Accordingly, the present invention provides a new twig saw top structure and a method of forming and processing the saw blade, which can cut the branches having a small thickness and a weak thickness with a certain degree of cutting force, while minimizing the resistance in the sawing process. And it was completed as a technical problem.
In order to accomplish the above object, according to the present invention, there is provided a
As described above, the saw cut-only saw structure according to the present invention and the saw blade forming method of the present invention have the additional saw blades formed on the concave side of the other side as well as the one convex side of the curved body steel sheet, Since both branches can be cut using both directions, it is possible to cut off the upper and lower cutting edges of the branches even if the bar 300 (including the heavy and long saw) And the manufacturing process of the saw blade including the saw blade can be greatly simplified and simplified by using the laser cutting method which has never been tried in the saw blade field at least in the shaping and processing of the saw blade In addition, the time and cost of the operation can be greatly reduced compared to the existing one, which is expected to contribute considerably to the cost reduction. Is a useful invention.

As the need arises, for the purpose of increasing the cutting force, a slanting chamfer is formed on both sides of the tooth so as to form a sharp edge, and adjacent teeth are chamfered on both sides opposite to each other so that the pointed portions between the teeth are shifted from each other, A step of raising a saw tooth to further exert an effective cutting force on the workpiece W can be further performed.
In this case, the blade cutting operation can be performed using the polishing method which was used in the previous blade manufacturing, but the laser cutting technique used in forming the saw blade of the present invention can be used.
That is, when cutting is performed by inclining the angle of irradiation of the laser beam when the blade is slanted by performing a slanting chamfering process on one side of each of the saw blades cut by the laser and opposite sides of the opposite sides of the other side, It can be a day cutting method.
