Description
Technical field
The present invention relates to disc cutter production field, concretely relate to the upstream auxiliary mould of a kind of disc cutter compacting.
Background technology
Disc cutter, also known as cutting disc, is usually used in the work such as polishing, cutting, has market widely at mechanical field.Existing
Disc cutter production process in, use pellet or powder pressing to become semi-finished product disk, high temperature sintering realizes consolidation molding afterwards.But
The existing compressing difficulty of semi-finished product disc cutter, due to semi-finished product be relatively large in diameter, the thinnest, when using pellet compacting, half becomes
Product density is poor, and product is difficult to put on ware dish, and product metallographic can not be guaranteed.If use powder pressing, powder flows
Property is poor, is easily caused compacting non-uniform charging so that after sintering, deformation of products is big.Therefore, for disc cutter in prior art
Producing, its percent defective is the highest, wastes the biggest.
Summary of the invention
The present invention proposes the upstream auxiliary mould of a kind of disc cutter compacting, to solve the problems referred to above of the prior art, real
Now reduce disc cutter and produce the purpose of percent defective.
The present invention is achieved through the following technical solutions:
The upstream auxiliary mould of a kind of disc cutter compacting, including charging aperture, described charging aperture is provided with the mistake that mesh number is 20 mesh
Filter screen, charging aperture is communicated to teeter chamber, arrange agitating device in described teeter chamber, arranges vibration below the discharge end of teeter chamber
Sieve, described vibrosieve has three-layer screen, and three-layer screen its mesh number from top to bottom is followed successively by 40 mesh, 60 mesh, 80 mesh, described vibration
Material-receiving device is set below sieve.
One-time success rate compressing in disc cutter production process in prior art is less than 20%, and percent defective is high, and waste is very
Greatly, for this problem, the present invention proposes the upstream auxiliary mould of a kind of disc cutter compacting.Mixing raw material is entered by charging aperture and stirs
Mix indoor, charging aperture arranges the drainage screen of 20 mesh, in order to filter out the foreign material in raw material, it is ensured that the compound carrying out suppressing is done
Clean no-sundries.Agitating device is set in teeter chamber, for will compacting disc cutter raw material stirring uniform, it is ensured that subsequent handling be
Carry out in the case of raw material is uniform, it is ensured that the disc cutter metallographic stable and uniform of compacting.Below the discharge end of teeter chamber, vibration is set
Sieve, utilizes vibrosieve to screen compound.Described vibrosieve has three-layer screen, and three-layer screen its mesh number from top to bottom depends on
Secondary is 40 mesh, 60 mesh, 80 mesh, is i.e. that the eyelet of three-layer screen from top to bottom tapers into, by three-layer screen screening successively
Filtering, reduce the operating pressure of monolayer screen cloth, finishing screen is selected can be by the pellet of 80 eye mesh screens and powder.If sieve mesh
Number is the least, pellet large percentage in the compound sifted out, and owing to there is gap between adjacent pellet all the time, and now powder is not enough
To fill up all of gap, the disc cutter Density Distribution that i.e. can cause compacting is uneven, and metallographic can not be guaranteed.Otherwise, if screen cloth
Mesh number is too big, and in the compound sifted out, powder ratio is excessive, the mobility of compound, granularity can be caused to be decreased obviously, make
Before becoming compacting, the charging in mould is irregular, and after causing sintering, deflection is big, is unfavorable for that the compacting of circular knife produces equally.And
Its aperture of the screen cloth of 80 mesh is near 180 microns, it is possible to avoids the pellet that particle diameter is bigger to enter and produces, meets powder simultaneously and lead to
Cross so that entering the raw material of pressing stage, its size is uniform and stable, does not haves the situation that the gap between pellet is suddenly big or suddenly small,
So that it is guaranteed that the semi-finished product circular knife suppressed has good metallographic, its Density Distribution is the most uniform and stable, can make with this
The one-time success rate of compacting semi-finished product circular knife is improved, and reduces cost.If additionally, use monolayer 80 eye mesh screen, can cause
This layer of screen cloth load-carrying is too big, has a strong impact on screening efficiency, and causes sieve breakage to be accelerated, and replacement frequency is greatly improved, and causes
Cost raises, and therefore the present invention arranges the mesh structure of three layers of gradually filtering type, reduces the operating pressure of monolayer screen cloth, improves sieve
In the service life of net, reduce cost.Additionally, arrange material-receiving device below described vibrosieve, screen from vibrosieve in order to collect
Compound out.
Further, described material-receiving device is belt conveyor.The compound screened from vibrosieve directly drops
On belt conveyor, thus it is immediately conveyed to the manufacturing side easily and fast and carries out filling compacting, improve production efficiency, save people
Power cost.
Further, described vibrosieve is linear vibrating screen.Linear vibrating screen utilize vibrating motor exciting as vibration source,
Make material tossed on screen cloth, the most for linear motion.Linear vibrating screen have power consumption low, efficiency is high, simple in construction,
The features such as easy-maintaining, are more suitable for the rapidly and efficiently operation of streamline.
Further, described charging aperture has multiple, and multiple charging apertures are all communicated to teeter chamber.Improved by multiple charging apertures
Powder feeding efficiency, it is to avoid the situation that after single charging aperture generation congestion situations, whole device i.e. cannot be properly functioning occurs.
Further, described agitating device is blender.Blender utilizes blade to rotate in teeter chamber, thus to compacting
The raw material of disc cutter is stirred mixing, full and uniform to guarantee to mix, and is capable of the automated production of higher degree simultaneously.
The present invention compared with prior art, has such advantages as and beneficial effect:
The upstream auxiliary mould of a kind of disc cutter of present invention compacting, including charging aperture, it is 20 purposes that charging aperture is provided with mesh number
Drainage screen, charging aperture is communicated to teeter chamber, arranges agitating device in teeter chamber, arranges vibrosieve below the discharge end of teeter chamber,
Vibrosieve has three-layer screen, and three-layer screen its mesh number from top to bottom is followed successively by 40 mesh, 60 mesh, 80 mesh, arranges below vibrosieve
Material-receiving device.The present invention arranges the mesh structure of three layers of gradually filtering type, reduces the operating pressure of monolayer screen cloth, improves screen cloth
In service life, finishing screen is selected can be by the raw material of 80 eye mesh screens so that entering the raw material of pressing stage, its size is the most steady
Fixed, do not have the situation that the gap between pellet is suddenly big or suddenly small, so that it is guaranteed that the semi-finished product circular knife suppressed has good
Metallographic, its Density Distribution is uniform and stable, with this realize improve compacting the one-time success rate of semi-finished product circular knife, rate of reducing the number of rejects and seconds,
Reduce the purpose of cost.
