Cutter link includes the left cutter link 3 and right cutter link 4 set in turn.
Described connection chain link is by two connection sheets 11 and is integrally attached between two connection sheets and is located at length side
Formed to the connecting portion 12 in centre position, connection chain link is by a complete sheet metal punch forming；In one connection sheet
Two huge linkage holes 62 are offered, the position of corresponding two huge linkage holes offers two small connections in another described connection sheet
Hole 61, the aperture of small connecting hole are less than the aperture of huge linkage hole；The inside and outside wall of the huge linkage hole, small connecting hole and connection sheet
Between form chamfering；Periphery in the outside wall surface of the connection sheet for having opened up small connecting hole positioned at small connecting hole forms
Recessed circle a14；Each connection sheet forms two symmetrically arranged branch fasteners 13 different from the side of connecting portion, branch fastener it is outer
Hold curved.
The hardness of the connection sheet is HRC46, the connecting portion, and connecting portion and the hardness of connection sheet connecting part is
HRC42.Connecting portion position is slightly soft to enable following lassos to fit more easily into.
It is connected with a lasso 56 in the connection chain link between relative huge linkage hole and small connecting hole, two of lasso
The clamping flange collar 562 being engaged with the chamfering position on huge linkage hole, small connecting hole, the periphery of lasso are formed on end face respectively
It is rotatably assorted and is connected with the connecting hole on driving piece, there is a positioning step portion 561, lasso inner circumferential position among the inner circumferential of lasso
In the both sides in positioning step portion be different two socket parts in aperture.
The hardness of the lasso periphery is HRC55, and the hardness of lasso inner circumferential is HRC40.Lasso periphery is with driving on piece
Connecting hole is rotatablely connected, and for hardness compared with high wear resistance, lasso inner circumferential hardness is slightly lower, is fitted close with rivet and forms certain radial direction
Pretightning force.

The cutting tip 34 away from connection part side in main connection sheet is connected to, and is integrally attached in main connection sheet and is located at cutting
Spacing first 33 in front of blade, a breach is left between spacing head and cutting tip；The left cutter link is complete by one
Sheet metal punch forming；Two huge linkage holes 62 are offered in the main connection sheet, it is corresponding two big in the secondary connection sheet
The position of connecting hole offers two small connecting hole 61, and the aperture of small connecting hole is less than the aperture of huge linkage hole；The big connection
Chamfering is formed between the inside and outside wall in hole, small connecting hole and connection sheet；It is located at little Lian in the outside wall surface of the secondary connection sheet
The periphery for connecing hole forms recessed circle b311；Also it is connected between relative huge linkage hole, small connecting hole in the left cutter link
Described lasso.
Described cutting tip is in integrally front wide and rear narrow taper cambered surface, and cutting tip and main connection sheet connected component are close
One end outward bending of spacing head, the front end of cutting tip are formed close to the first blade 341 of main connection sheet side and close
Second blade 342 of secondary connection sheet side, the first blade and the second blade joint form the point of a knife extended to cutting direction
343；Machine-shaping to form first blade, the respectively for the cutting tip front end and cutting tip internal face crossover position
The first grinding surface 3411 and the second grinding surface 3421 of two blades.
The ratio between radius of periphery residing for first grinding surface and the second grinding surface is 4 ﹕ 5, is justified residing for the first grinding surface
The radius of side face is 10mm；The axis p of circumference and left cut form 42 between cutting zip length direction residing for first grinding surface
The angle a of degree, 47 degree of angle is formed residing for first grinding surface between the axis of circumference and left cutter link width
c；The axis q of circumference and left cut residing for second grinding surface are cut and 48 degree of angle b are formed between zip length direction, and described the
127 degree of angle d is formed between the axis of circumference residing for two grinding surfaces and left cutter link width.
The point of a knife cut in left cut it is relative with spacing head on zip length direction, and among point of a knife and spacing head thickness direction
The distance between point t is 0.05mm；The distance between cutting tip front end outside wall surface and main connection sheet outer face s are 2mm；
First blade extends to cutting tip front Middle face position from cutting tip top surface medium position, due to so being cut
The wood chip cut off can be shredded again by the part that the first blade is located in the middle part of side, will not be stuck in gap position.Two blade phases
Position is handed over to form a fin, point of a knife is located at the top of fin, and the tail end of fin extends to main connection sheet side, so by the
The wood chip that two blades are cut can be pushed open by fin toward secondary connection sheet side, will not be snapped into breach side and be caused saw vessel used to hold grain at the imperial sacrifice can not be normal
Work.
The main connection sheet, the hardness of secondary connection sheet are HRC47, the connection part, and connection part and main connection sheet, pair
The hardness of connection sheet connecting part is HRC43, and cutting tip front portion hardness is HRC60, cutting tip rear portion hardness
For HRC52.
Cutting tip, spacing head, huge linkage hole and the small connecting hole of the right cutter link cut cutting for chain link with respect to left cut
Paring blade, spacing head, huge linkage hole and small connecting hole specular are set, and the mirror image face of the specular is and main connection
Piece, secondary connection sheet be parallel and equidistant plane.The main connection sheet, the saying of secondary connection sheet are only easy for describing part
Position relationship, without the major-minor on essential meaning point.
The rivet is made up of the manufactured head 51 of integrally connected successively, thick bar portion 52, thin rod part 53 and riveting end 55, thick bar
Portion forms a positioning shoulder 54 with thin rod part connecting position；Rivet penetrates from huge linkage hole, is passed from small connecting hole, the positioning
Shoulder is engaged with the positioning step portion of lasso, and thick bar portion, thin rod part are interference fitted with two socket parts of lasso inner circumferential respectively to be connected
Connect；After the riveting end forms riveting first 550 by pendulum stone roller riveting, the inwall of riveting head corresponds to recessed circle a, recessed circle b position shape
Into the riveting ring 551 being engaged with recessed circle a, recessed circle b.
The periphery hardness that the rivet is located at thin rod part and riveting end junction is HRC29, riveting end other parts
Hardness be HRC36, the hardness of the rivet other parts is HRC59.Thin rod part is hard with the periphery of riveting end crossover position
The relative other positions of degree are minimum, so after the shaping of riveting end riveting, the minimum region of the hardness be squeezed to be formed compared with
High density, and formed closely with small connecting hole with generation pretightning force is merged, it is not likely to produce loosening.
HRC described in text is the C scale of Rockwell hardness scale.
Embodiment 2
