Abstract
The utility model relates to a compound dull and stereotyped round -hole punched plate of material screening belongs to the material and carries the equipment field. Among the modern industry, screening equipment commonly used carries out grading of granule size to the material, and the sieve is very crucial among a screening equipment parts, and in the course of the work with material direct contact, the impact abrasion who bears the material acts on, and is consequently very high to the requirement of its wearability. The utility model discloses containing the steel sheet, being equipped with the sieve mesh on the steel sheet, the complex has the wearing layer around steel sheet upper surface sieve mesh, and the disperse distributes in the wearing layer has super high hardness wear resistant particles, and its thickness is between 2~3 millimeters. Because the hardness of wearing layer is much higher than in the hardness, especially wearing layer of steel sheet still disperse and distributes and have the wear resistant particles of super high hardness, therefore wear resistance improves greatly, compares with the sieve of clean steel board preparation, and life prolongs greatly, has very obvious advantage, can use in the screening field that has the special requirement to wear resistance.
Description
Technical field
This utility model is related to a kind of compound slab round-hole punched plate for material screening, belongs to material conveying equipment neck
Domain.
Background knowledge
In modern industry production, conventional screening plant carries out the classification of granular size to material, and sieve plate is in screening plant
A very crucial part, in the course of the work with material directly contact, bears the impact erosive wear effect of material, therefore
Requirement to its wearability is very high.The sieve plate being industrially most widely used is braided steel wire sieve plate, and this sieve plate is in work
During the easy wear and rupture of steel wire, therefore service life is very short.It is a large amount of at present to be made using steel plate in order to solve this problem
To make the raw material of sieve plate, this sieve plate processes sieve aperture on steel plate, because the wear-resisting area and thickness of steel plate typically set
It is calculated as being greatly improved compared with braided steel wire screen cloth more than gauge of wire used by woven screen, therefore anti-wear performance.But it is right
For current big commercial production, very big due to crossing doses on sieve plate, a hour for having can reach more than 500 tons, therefore
Existing steel plate sieve plate still cannot effectively achieve the requirement of sieve plate service life.Need to replace using new sieve plate for this
The sieve plate that existing plain plate makes.
Utility model content
The purpose of this utility model is just to provide a kind of compound slab round-hole punched plate, and it can efficiently solve existing steel plate sieve
The problems of plate.
What the purpose of this utility model was realized in：A kind of compound slab round-hole punched plate for material screening, comprising
Plain plate (1), plain plate is provided with rotary strainer hole (2), and wearing layer (3) is compounded with around plain plate upper surface rotary strainer hole, described
Dispersed precipitate has ultrahigh hardness abrasion resistant particles (4) in wearing layer.
Rotary strainer hole on the plain plate is up-small and down-big with gradient bellmouth.
The width of wearing layer is between 5～10 millimeters around the rotary strainer hole.
The thickness of the wearing layer is between 2～3 millimeters.
The ultrahigh hardness abrasion resistant particles of Dispersed precipitate is shaped as polygon in the wearing layer.
One layer of wearing layer is combined around original flat board sieve plate upper surface rotary strainer hole, its hardness is much higher than steel plate sheet
The hardness of body, therefore its anti-wear performance is also much higher than steel plate itself, so, so that it may greatly improve original steel plate stamped sieve plate
Service life.Due to being position that material is easiest to wear and tear around sieve aperture, therefore only 5～10 millimeters of the model around rotary strainer hole
Interior composite wear-resistant layer is enclosed, the consumption of composite material can be effectively reduced, reduce production cost.
Anti-wear performance is had on the sieve plate of requirements at the higher level at some, mix wear-resisting of high rigidity in advance in composite
Grain, these granules Dispersed precipitate in recombination process in wearing layer, can further improve the anti-wear performance of wearing layer, so as to
Further improve the service life of sieve plate.High hard abrasion resistant particles are shaped as polygon, can increase high hard abrasion resistant particles and base
Bonding strength between body metal, improves the reliability of wearing layer.
The THICKNESS CONTROL of wearing layer ensure that the Acceptable life of sieve plate between 2～3 millimeters, while producing work
Also it is easily controlled in skill and realizes, with particular advantage.
Rotary strainer hole on plain plate is up-small and down-big with gradient bellmouth.Card of the material in sieve aperture can be prevented
It is stifled, improve the sieve plate reliability for using and the service efficiency for ensureing sieve plate.
Description of the drawings
Accompanying drawing show structure principle chart of the present utility model, and wherein Fig. 1 show the top view of Fig. 2, and Fig. 2 show figure
The sectional view of A--A positions in 1.
Specific embodiment
Accompanying drawing show embodiment of the present utility model, and in fig. 1 and 2,1 is steel plate, and 2 is sieve aperture, and 3 is wearing layer, and 4
For the ultrahigh hardness abrasion resistant particles of Dispersed precipitate in wearing layer, polygon is shaped as.5 is the installation of plate compounding round-hole punched plate
Hole.
In this embodiment, plain plate 1 adopts normal carbon steel plate, and the sieve aperture 2 of up-small and down-big conical bore is machined with thereon,
It is provided with round installing hole 5 on four angles of sieve plate simultaneously.One layer of wearing layer 3, wearing layer are compounded with around upper surface of steel plate sieve aperture
Interior Dispersed precipitate has ultrahigh hardness abrasion resistant particles 4.During plate compounding round-hole punched plate screening materials carrying, material is from plain plate
And pass through on the wearing layer around rotary strainer hole, the erosive wear due to being most susceptible to material around rotary strainer hole, and apart from sieve aperture
Then wear and tear relatively slight at plain plate farther out, therefore compound wearing layer can effectively improve the anti-wear performance of sieve plate.Brush hits
Wearing layer is hit, but does not reach steel plate, because the hardness of wearing layer is much higher than in the hardness of steel plate, particularly wearing layer also more
The abrasion resistant particles that ultrahigh hardness is distributed with are dissipated, therefore anti-wear performance is greatly improved, and compared with the sieve plate that clean steel plate makes, is used
Life-span greatly prolongs, and with obviously advantage, can apply in the screening field for having particular/special requirement to anti-wear performance.
