Abstract
The utility model discloses a saw chain gear cutting piece puts first edge on a knife or a pair of scissors, the blade of gear cutting piece after putting the first edge on a knife or a pair of scissors be including top sword and kicker, the top sword be the straightway, the kicker be ARC segments, the edge of a knife of blade is 60 2.5 with the contained angle of saw chain transmission direction. The utility model discloses an optimize edge of a knife shape and angle, greatly improved the result of use of very hateful piece.
Description
Technical field
The utility model relates to saw chain, particularly relates to saw chain cutting teeth sheet and puts the first edge on a knife or a pair of scissors.
Background technology
Cutting sheet is put the first edge on a knife or a pair of scissors by wheel grinding, obtains certain knife edge shape and angle after putting the first edge on a knife or a pair of scissors, and the shape of the knife edge and the performance of angle on cutting sheet have remarkable impact, but the design of knife edge shape and angle still has larger room for improvement at present.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of saw chain cutting teeth sheet and puts the first edge on a knife or a pair of scissors, and is improved the result of use of cutting sheet by optimization knife edge shape and angle.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: saw chain cutting teeth sheet puts the first edge on a knife or a pair of scissors, and the cutting edge after cutting sheet puts the first edge on a knife or a pair of scissors comprises top sword and side edge, and described top sword is straightway, described side edge is arc, and the knife edge of cutting edge and the angle of saw chain transmission direction are 60 ° ± 2.5 °.
Preferably, the angle of described top sword and upper knife face is 52 ° ± 2.5 °.
Preferably, the angle pushing up sword forward terminal and the line between top sword and side edge transfer point and vertical direction is 21 ° ± 3 °.
Preferably, the knife back elevation angle when cutting sheet knife back is shaping is 7 ° ± 1.5 °.
The utility model, by optimizing knife edge shape and angle, greatly improves the result of use of cutting sheet.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is the front schematic view of saw chain;
Fig. 2 is the schematic diagram of the saw chain cutting teeth sheet knife edge;
Fig. 3 be saw chain entirety face upward 28 degree time schematic diagram;
Fig. 4 is the perspective view of Fig. 3;
Fig. 5 is E place amplification assumption diagram in Fig. 4.
Detailed description of the invention
The knife edge shape that saw chain cutting teeth sheet is obtained after being put the first edge on a knife or a pair of scissors by wheel grinding and angle are as shown in Figures 1 to 5, cutting sheet 1 is located on saw chain matrix 2, cutting sheet 1 is become one structure by the mode of welding and saw chain matrix 2, and the knife edge angle shown in Fig. 1 to Fig. 5 is one of them preferred value.
As shown in Figure 1, the cutting edge after saw chain cutting teeth sheet 1 puts the first edge on a knife or a pair of scissors comprises top sword 11 and side edge 12, and described top sword 11 is straightway, and described side edge 12 is the arc of circular arc recess, and top sword 11 and side edge 12 coordinate formation cutting edge, cut timber.
In addition, also illustrate in Fig. 1, the angle of top sword forward terminal and line and vertical direction between top sword and side edge transfer point is 21 ° ± 3 °, and preferably 21 °, this angle can ensure the wearability of the knife edge, makes the cutting sheet knife edge can not rust rapidly.
The knife back elevation angle when cutting sheet knife back 15 is shaping is 7 ° ± 2.5 °, is preferably 7 °, and along with the increase of service time, limiting tooth wearing and tearing on front side of cutting sheet, this angle enables the knife edge cut timber smoothly, ensures that cutting sheet cuts lumber thickness and stablizes.
As shown in Figure 2, the knife edge 13 of cutting edge is 60 ° ± 2.5 ° with the angle of saw chain transmission direction, is preferably 60 °.This angle is cutting angle, and making the knife edge enter the state of timber for progressing into, is oblique along the cutting edge of cutting sheet by drag decomposition.
As shown in Figures 3 to 5, saw chain entirety face upward 28 degree time project, can find out, top sword 11 is 52 ° ± 2.5 ° with the angle of upper knife face 14, is preferably 52 °.This angle ensures that cutting sheet cutting edge has and keeps good sharpness.
Claims (4)
1. saw chain cutting teeth sheet puts the first edge on a knife or a pair of scissors, and it is characterized in that: the cutting edge after cutting sheet puts the first edge on a knife or a pair of scissors comprises top sword and side edge, and described top sword is straightway, and described side edge is arc, and the knife edge of cutting edge and the angle of saw chain transmission direction are 60 ° ± 2.5 °.
2. saw chain cutting teeth sheet according to claim 1 puts the first edge on a knife or a pair of scissors, and it is characterized in that: the angle of described top sword and upper knife face is 52 ° ± 2.5 °.
