Abstract
The utility model relates to a hardware tool, particularly a gear tool connecting sheet for a saw chain when wood is sawed. The left upper part of the connecting sheet is provided with a cutting plane, a cutting side, a cutting edge of the cutting plane and a cutting edge of the cutting side. The right upper part of the connecting sheet is provided with stuff limiting teeth, and the lower part of the gear tool connecting sheet for a saw chain is provided with saw chain holes. The utility model is characterized in that the cutting edge of the cutting side presents a flat shape, and the included angle of the cutting edge of the cutting plane and the cutting edge of the cutting side is less than 90DEG. After the utility model is used, the cutting resistance is reduced, the cutting performance is improved, and the cutting efficiency is enhanced.
Description
The utility model relates to a kind of hardware ﹠ tools, and used saw chain cutting in flakes when referring in particular to a kind of sawmilling material.
Saw chain is the workpiece of chain saw and electric chain saw, is a kind of flexible cutting tool of particularity.The cutting ability of saw chain to the productivity ratio of saw chain complete machine and unit cost of production influence greatly also has certain influence to operator's labour intensity and personal safety.Along with the update of saw chain, external saw chain has progressively captured the saw chain market of China with its superiority.Therefore, the cutting ability that improves homemade saw chain has become regenerates one of manufacturing key technology of China's saw chain, and saw chain cutting cutting ability has in flakes directly determined the cutting ability of whole piece saw chain.
The cutting ability of saw chain mainly comprises sharpness and advances to saw resistance, the tradition saw chain cutting cutting edge 4 of 7 cutting side 2 in flakes is circular arc, as shown in Figure 1, 2, the fatal shortcoming that this kind cutting edge exists is a cutting edge grinding difficulty, the uniformity of its back angle and arc radius is difficult to be guaranteed, like this, its sharpness is just had a greatly reduced quality, owing to can not guarantee the uniformity of arc radius, during cutting, the depth gauge h disunity of each cutting chain on the whole piece saw chain, and, the area of cut is bigger during cutting, thereby advances to saw resistance and obviously increase.
The purpose of this utility model is to seek a kind ofly to reduce cutting resistance, improve cutting ability, improve the saw chain Cutting teeth chair blade of stock-removing efficiency.
Its main technical schemes is in saw chain cutting left upper portion in flakes cutting plane, cutting side and cutting plane cutting edge and cutting side cutting edge to be arranged, at the limited material tooth of its right upper portion, in saw chain cutting bottom in flakes the saw chain hole is arranged, it is characterized in that cutting the side cutting edge and be plane.
Its another feature is that angle between cutting plane cutting edge and the cutting side cutting edge is less than 90 °; The cutting plane angle of inclination beta is 1 °～7 °; The thinnest part thickness of cutting edge is more than or equal to 1.3 millimeters.
The utility model has the advantages that because cutting side cutting edge is plane, avoided original back angle and arc radius to be difficult to unified problem, itself and the angle that cuts between the cutting edge of side are acute angle, thereby be convenient to the grinding cutting edge, guaranteed the sharp of cutting edge, improved the sharpness of saw chain, cutting resistance has been reduced to minimum zone, improve cutting ability, improved stock-removing efficiency effectively.
Fig. 1 is an existing saw chain cutting structure chart in flakes.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is a structure chart of the present utility model.
Fig. 4 is the left view of Fig. 3.
As Fig. 3, shown in 4: the saw chain cutting in flakes 9 upper left quarter crossing cutting plane 1 and cutting side 12 are arranged, and the cutting plane cutting edge 3 that forms by the right side of plane 1 and side 12 and cut side cutting edge 8, and, between cutting plane cutting edge 3 and the cutting side cutting edge 8 angle---the cutting angle is less than 90 °, one gap 10 is arranged 9 top in flakes in the saw chain cutting, be used for grinding cutting plane cutting edge 3 and cutting side cutting edge 8, its right-hand member is a limit material tooth 5, spacing h between the upper surface of this limit material tooth 5 and the top of cutting plane cutting edge 3 is depth gauge, be used to control the depth of cut of saw chain, at saw chain cutting 9 uniform two chain-axis holes 6 in bottom in flakes, be used to install saw chain.The cutting plane angle of inclination beta is 1 °, and cutting side inclination alpha is 5 °, and the angle of β and α changes and should guarantee cutting plane cutting edge 3 and cut angle between the side cutting edge 8 less than 90 °.The thinnest part thickness of cutting edge is more than or equal to 1.3 millimeters, to guarantee the cutting hardness of cutting edge.
