Abstract
The utility model provides a knife edge joint type cutting knife, composed of a superfine and hard alloy knife edge with high abrasion-proof and cutting ability, and a body made of metal alloy material, such as iron, steel, etc. with low price. Consequently, the utility model ensures the service life of the cutting knife, reduces the price, and is easy to popularize for the chemical fibre industry.
Description
The utility model relates to a kind of fibre cutting cutter that is used for the field of textiles chemical fibre industry.
Domestic in chemical fibre industry, the whole ultra-fine cemented carbide blank of sinter molding that adopts of the cutoff tool of representative level is through processing in the short fiber production at present.This monoblock type cutoff tool as shown in Figure 1, its advantage is that hardness height, wearability are good, according to different its single of the fiber object of producing service life be tens hours to several days, the certain number of times of sharpening repeatedly is so use is longer entire life.This monoblock type cutoff tool can not be again with scrapping owing to highly lowering behind the certain number of times of sharpening in the production.Its shortcoming is to adopt the ultra-fine cemented carbide material to cause owing to the monoblock type cutoff tool is whole to cost an arm and a leg.External development in recent years a kind of surface-treated steel cutoff tool that gets up, its advantage is that price is low, its shortcoming is that this monoblock type cutoff tool use once must be scrapped, and single is shorter service life than the single of ultra-fine cemented carbide cutoff tool service life, need frequent tool changing influence to produce in causing producing, so do not accepted by domestic users.
Analyze from life-span, price and the existing cutter kind of cutoff tool, the parent of cutoff tool separates with cutting edge, adopts the different material of both performances, makes made cutoff tool not only guarantee the life-span but also reduce price, and the life-span/price index that promptly improves cutoff tool is its research direction.
The purpose of this utility model is to provide a kind of blade engagement type cutoff tool.
Blade engagement type cutoff tool of the present utility model as shown in Figure 2.It is made up of knife edge part 1 and parent fraction 2, and both link into an integrated entity by adhesive.The shape of knife edge part 1 and parent fraction 2 is respectively shown in Fig. 3 (a) and Fig. 3 (b).Its size relationship is: B=(1.5～1.85) * B
1Mm, B
2=B
1Mm, H
2=(H
1～40) mm, α=5～30 °, θ=10～75 °, wherein 0.4mm≤B
1≤ 2.5mm, 4mm≤H
1≤ 25mm.The material of knife edge part 1 adopts ultra-fine cemented carbide, and the material of parent fraction 2 adopts iron and steel or other metal alloy compositions.Adhesive adopts homemade trade mark products such as SA-201, SA-202, anchor 350,420 glue all can.
The utility model has the advantages that owing to adopted the ultra-fine cemented carbide blade of high abrasion cutting power and cheap metal alloy compositions parents such as iron and steel to form, though thereby service life is basic identical with former whole cutoff tool, but the cutter cost of raw material reduces, and life-span/price index is greatly improved.
Accompanying drawing of the present utility model has:
Fig. 1 is a monoblock type cutoff tool schematic diagram
Fig. 2 is a blade engagement type cutoff tool schematic diagram
Fig. 3 is a blade engagement type cutoff tool decomposing schematic representation
Blade engagement type cutoff tool is in when work, and what chemical-fibres filaments was played cutting action is knife edge part, and parent fraction plays the support reinforcing effect.
