Abstract
The utility model discloses a chemical fiber cut-off tool which comprises a cutter body and a cutting edge arranged on the edge of one side of the cutter body. The cutting edge comprises a first cutting edge body and a second cutting edge body, wherein the second cutting edge body is arranged between the cutter body and the first cutting edge body, the cutting edge angle of the first cutting edge body is larger than that of the second cutting edge body, the cutting edge angle of the first cutting edge body is 30-45 degrees, the cutting edge angle of the second cutting edge body is 4-25 degrees, the cutting edge angle of the first cutting edge body is 30 degrees, the cutting edge angle of the second cutting edge body is 17 degrees, the cutting edge angle of the first cutting edge body is 42 degrees, the cutting edge angle of the second cutting edge body is 17 degrees, the cutting edge is made of hard alloy, and the surface roughness of the first cutting edge body and the surface roughness of the second cutting edge body are both 0.02 micrometer. The cutting edge of the chemical fiber cut-off tool is designed to be double, when the chemical fiber cut-off tool is used for cutting chemical fibers, friction force between the cutting edge and the chemical fibers can be effectively reduced, and incision orderliness is guaranteed.
Description
Technical field
The utility model relates to the cutter field, especially a kind of cutter blade.
Background technology
Cutoff tool is the vital part on the chemical fibre cutting machine, and cut-out quality and the efficiency of chemical fibre is had to critical impact.In prior art, the blade of cutter blade is the substance cutting edge, and in cutting process, between cutting edge and chemical fibre, frictional force is large, and otch is coarse, cuts off effect bad.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of cutter blade that can reduce frictional force between cutting edge and chemical fibre.
The utility model solves the cutter blade that its technical problem adopts, comprise cutter hub and the blade that is arranged on this cutter hub one lateral edges place, described blade comprises the first heavy cutting edge and the second heavy cutting edge, the second heavy cutting edge is between cutter hub and the first heavy cutting edge, and the blade angle of the first heavy cutting edge is greater than the blade angle of the second heavy cutting edge.
Further, the blade angle of described the first heavy cutting edge is 30 °～45 °, and the blade angle of described the second heavy cutting edge is 4 °～25 °.
Further, the blade angle of described the first heavy cutting edge is 30 °, and the blade angle of described the second heavy cutting edge is 17 °.
Further, the blade angle of described the first heavy cutting edge is 42 °, and the blade angle of described the second heavy cutting edge is 17 °.
Further, the material of described blade is carbide alloy.
Further, the surface roughness of the described first heavy cutting edge and the second heavy cutting edge is 0.02um.
The beneficial effects of the utility model are: the blade of cutter blade is set to double cutting edge, in the use cutter blade is cut the process of chemical fibre, can effectively reduce the frictional force between cutting edge and chemical fibre, guarantees that otch is neat.
The accompanying drawing explanation
Fig. 1 is top view of the present utility model.
Fig. 2 is left view of the present utility model.
Fig. 3 is the partial enlarged drawing of A in Fig. 2.
In figure, indicate: 1-cutter hub, 2-blade, the heavy cutting edge of 21-first, the heavy cutting edge of 22-second.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
as Fig. 1, shown in Figure 2, cutter blade of the present utility model, comprise cutter hub 1 and the blade 2 that is arranged on these cutter hub 1 one lateral edges places, described blade 2 comprises the first heavy cutting edge 21 and the second heavy cutting edge 22, the second heavy cutting edge 22 is between cutter hub 1 and the first heavy cutting edge 21, the blade angle of the first heavy cutting edge 21 is greater than the blade angle of the second heavy cutting edge 22, in the use cutter blade is cut the process of chemical fibre, when chemical fibre passes through the corner between the first heavy cutting edge 21 and the second heavy cutting edge 22, this corner separates chemical fibre with the first heavy cutting edge 21, so just can effectively reduce the frictional force between chemical fibre and the first heavy cutting edge 21, the assurance otch is neat.
As shown in Figure 3, the blade angle of the described first heavy cutting edge 21 is 30 °～45 °, preferred 30o and 42o; The blade angle of the described second heavy cutting edge 22 is 4 °～25 °, preferred 17 °; Blade angle is controlled in described scope, can improve the durability of cutting edge 21, thereby improves the service life of cutter blade.
The material of described blade 2 is carbide alloy, and Cemented Carbide Hardness is high, and wearability is good, and the carbide alloy cutoff tool is higher 4～7 times than the cutting speed of high-speed steel cutoff tool, and cutter life is high 5～80 times.
The surface roughness of the described first heavy cutting edge 21 and the second heavy cutting edge 22 is 0.02um, arrives mirror status more than 12 grades, has effectively overcome viscose glue, has reduced frictional force.
