Abstract
The roller for metal card clothing of casting belongs to technical field of textile machine, can reduce the cost of carding machine roller for metal card clothing, and roll is to form through forging, car, quenching, mill with expensive high-speed tool steel at present, finished product only is 40% of a blank, waste is many, cost height, difficult processing.Adopt casting roll, available particle and recovery waste material, yield rate height, cost only reach 1/3rd of forging.
Description
The invention belongs to technical field of textile machine.
Produce the carding machine roller for metal card clothing at present and adopt expensive high-speed tool steel bar, form through forging, turning, quenching, grinding.Be a metal integral, have two large problems in the production.(1) solid forging, each part need the monoblock blank of certain size and weight, have crack defect promptly to scrap in the forging slightly.The roll of (2) one pairs of external diameter φ 205 need blank 70-80Kg, and finished product net weight 28.2Kg has wasted more than 60%, so roll cost height, and it is difficult to produce.But over nearly 25 years, all be to make like this, do not improve in field of textile machinery.
The invention proposes a kind of new fabrication scheme, to save material, reduces cost.
This programme is to adopt casting to reach this purpose.The high-speed tool steel roll of casting, be considered to the high-speed tool steel roll that its performance is lower than forging, this is a kind of traditional view, thereby textile machine circle engineering staff has no talent and adopts casting to make roll, the experiment proved that now two kinds of roller for metal card clothing have same result of use, its service life is all than long four to five times of the card clothing roll campaign of forging with the GCr15 bearing steel, and therefore the roll of casting can replace the card clothing roll that forges.
Casting method has multiple, as gravitational casting, wax pattern casting, compression casting, centrifugal casting, hot investment casting or the like, adopt any method can, but necessarily require roll that defectives such as any airhole must not be arranged.This requirement is than higher, but experiment showed, that adopting correct technology is can cast out qualified product fully.
Prove in the experiment, the card clothing roll that uses materials such as Cr12, GCr15 to make, be short service life, in every case be temperature at the material that still can keep the hardness more than the HRC60 more than 540 ℃, the roll of making all can have identical or approaching result of use or better effect with the roll that high-speed tool steel is made.
The card clothing roll can adopt the casting manufacturing, has enlarged the material source scope.The ultrahard material that some can't forge can be cast application, and this improves hardness just for the card clothing roll and has opened up new road.
In order further to save expensive material, can cast the major part of roll work separately, then, become the assembly roller that replaces solid roll with other part combinations.
Casting roll and forging roller have same or approaching result of use, but cost has a great difference, with the present price counting, forge a secondary roll, cost is above 2,000 yuan, and adopt casting to be no more than 700 yuan, essential monoblock material with a certain size when forging only reaches the former 1/3rd, because have incompleteness promptly to make waste material slightly, therefore this programme is the right way that reduces cost, saves material, makes full use of the expensive saving energy increase wealth of society, and good economic effect is arranged.
Claims (3)
1, a kind of roll of producing carding machine metallic card clothing is characterized in that: process after the solid roll casting.
2, roll according to claim 1 is characterized in that: founding materials is high-speed tool steel or the material that still has high rigidity through high tempering.
3, roll according to claim 1 is characterized in that: roll can be made up of two or more parts, and wherein a part is cast.
