Description
Technical field
The utility model is related to grinding wheel manufacturing technology fields, and in particular to be a kind of boart boart with seedpod of the lotus structure
Wheel.
Background technology
Grinding wheel can be divided into metal base grinding wheel and non-metal base grinding wheel, either metal base grinding wheel and non-metal base grinding wheel,
The bonding agent of grinding wheel influences intensity, impact resistance, heat resistance, the corrosion resistance etc. of grinding wheel, and to grinding accuracy and grinding efficiency
Have a great impact.Non-metal base grinding wheel is to represent resin wheel preferable elasticity and yielding since matrix has with phenolic resin
Property, vibration and impact can be absorbed, but heat resistance is bad and abrasive grain is easy to fall off, durability is not high.Metal base grinding wheel is because have
Rigidity is big, the high feature of durability, so metal base grinding wheel is 3 times of resin bond wheel service life or more.But it is golden
Belonging to base grinding wheel, equally there is also deficiencies, by taking Metal Substrate super-hard abrasive (diamond) grinding wheel as an example, Metal Substrate super-hard abrasive (Buddha's warrior attendant
Stone) grinding wheel has rigidity big, and the high feature of durability is suitble to highly-efficient processing, but because its deformability is poor, so being unfavorable in precision

The cyclic annular foam element 5 of fat bond diamond grinding block 3.
(3) grinding wheel integral foam plastic pattern is prepared：It is embedded with the resin bonding agent diamond by what is obtained in step (2)
The cyclic annular foam element 5 of abrading block 3 is placed in the center of 6 cavity of foaming mould, then diamond particles, the PS beads of prefoam
The ratio of diamond concentration of the PS foamed plastics powder to have foamed on a small quantity as framework material routinely is mixed into composite wood
Material, then composite material is inserted in the annular gap that the annular foam part is constituted with cavity, after hot-pressing and foaming is molded, obtain
The diamond grinding layer composite foam to combine together with the cyclic annular foam element 5 and the resin bonding agent diamond abrading block 3
Model 7, the ring-type foam element 5,7 structure of the resin bonding agent diamond abrading block 3 and diamond grinding layer composite foam model
At complete grinding wheel block mold 8.
(4) foamed plastics casting model is prepared：First dead head 9 is cut into foamed plastics (i.e.：Running channel), then take step
Suddenly two complete grinding wheel block molds 8 that prepared by (3) are connect with the dead head 9 being cut into foamed plastics, then to bubble
The outer surface application fireproof coating of dead head 9 and two complete grinding wheel block molds 8 that foam plastics are cut into and it is dry at
Reason, obtains required evaporative pattern casting model.
(5) cast molding：The evaporative pattern casting model obtained in step (4) is embedded in sandbox, sandbox is placed on routine
Three-dimensional bumper on carry out vibrations compacting, then sandbox is taken out from conventional three-dimensional bumper again, then again by sandbox
It is connect with conventional negative pressure equipment by tracheae, conventional negative pressure equipment vacuumizes sandbox by tracheae, past again after the completion of vacuumizing
The metal melt of sandbox casting high temperature obtains the grinding wheel for carrying 9 condensate of dead head, then will after casting completion after cooling knockout
Grinding wheel with 9 condensate of dead head is sent to dead head 9 is fallen by milling machine or lathe cut again on milling machine either lathe, obtains sand
Take turns blank.
(6) Shape correction：The grinding wheel blank obtained in step (5) is modified using dresser, is obtained with lotus
The skive of fluffy structure.
In step (1), press selects existing conventional hot press, when compacting, the fire resistant resin phenolic resin or poly-
Imide resin, select phenolic resin when, hot pressing temperature be 160~200 DEG C, select polyimides when, hot pressing temperature be 205~
245 DEG C, control unit pressure is 40~100MPa, is 10~30h the time required to solidification.
Preferably, when selecting phenolic resin, hot pressing temperature is 170 DEG C, 185 DEG C or 195 DEG C.Select polyimides
When, hot pressing temperature is 215 DEG C, 225 DEG C, 230 DEG C or 245 DEG C.Control unit pressure is 60MPa or 80MPa.Here needed for solidification
Time and hot press unit pressure are depending on the fire resistant resin of selection.
In the step, the binder of resin bonding agent diamond abrading block 3 is using modified phenolic resin (PF), modified phenol
Urea formaldehyde (PF) prepares resin bonding agent diamond abrading block 3 by the method for compression moulding.Using boron carbide B4C changes PF
Property, B4Part fugitive constituent is converted to amorphous carbon by the reactivity between the part fugitive constituent discharged in C and PF cracking process
And be retained in resinoid bond to the height carbon yield of resin, improve the density of resinoid bond, and resin is made to have
Certain selfreparing.The binder of resin bonding agent diamond abrading block 3 can also use the high temperature resistance phenolic aldehyde of inorganic-organic hybrid
Material of the resin as manufacture resin grinding block, the abrading block shape as obtained by particular mold compacting.
In step (2), the blind hole is on annular foam part outer round surface with regular array or irregular arrangement form cloth
It sets, the resin bonding agent diamond abrading block 3 all has fixed part and grinding part, and the resin bonding agent diamond abrading block 3 is equal
Fixed part be inserted into the blind hole on the circumferential surface of annular foam element, the grinding part of the resin bonding agent diamond abrading block 3
Radial direction outside the circumference of the grinding wheel inner ring bubbles model of the annular shape protrudes.
Specifically：In the utility model, the fixed part of each resin bonding agent diamond abrading block 3 is cylinder boss structure, institute
State that diameter of blind hole is identical as the diameter of fixed part of the resin bonding agent diamond abrading block 3, the depth of the blind hole and institute
The height for stating the fixed part of resin bonding agent diamond abrading block 3 is consistent.The resin bonding agent diamond is enabled in this way
The fixed part of abrading block 3 is completely embedded into blind hole, and is fitted close with blind hole, so that resin bonding agent diamond abrading block 3
Fixation is more secured.Meanwhile matrix 1 and diamond grinding layer 2 can also be made not to have gap, it is convenient for diamond grinding layer 2
It is closely connect with matrix 1, is conducive to diamond grinding layer 2 and is securely fixed on matrix 1.
In step (3), conventional ratio refers to the common ratio of each material in super-abrasive grinding wheel working lining in the prior art,
Control diamond concentration is 80%-200%.The diamond concentration of common metal binding agent sand wheel is 75% to 150%.This ratio
Example is determined according to corase grinding or fine grinding and abrasive grain size, roughly grinds that the concentration used is smaller, and fine grinding is selected bigger dense
Larger concentration can be selected when smaller in degree abrasive grains.The process that the utility model prepares grinding wheel can prepare conventional ratio
Grinding wheel can also prepare more fine granularity grinding wheel.In step (4), vacuum pump may be used in conventional negative pressure equipment, high toward sandbox casting
The mode of the metal melt of temperature is bottom filling or top pouring type.Specifically：In step (4), lost foam casting uses one mould of bottom filling
Two chambers are molded, and can also be poured into a mould by the way of top pouring type.
In step (5), the mode toward the metal melt of sandbox casting high temperature is bottom filling or top pouring type.
In step (6), can also matrix 1 quickly first be modified using electrolysis, then golden with trimmer finishing resin binding agent
3 part of hard rock abrading block, to obtain that there is the skive of seedpod of the lotus structure.
It should be noted that：Abrasive grain used in the skive of the utility model is not limited to Buddha's warrior attendant stone mill
