Abstract
The invention discloses a kind of resin grinding wheel shaping methods that stock removal compensates automatically, including material mixing, molding, solidification, manufacturing procedure, cover half compression moulding is used in molding procedure, the upper surface of molding mass is spread to 2~5 ° outer low and inner high of inclined-plane with dedicated material scraper when scraper, it is suppressed using half heat pressing process, it is divided into 6 stage control pressing pressures and press temperature, maximum pressing pressure is 25N/m ㎡, and highest press temperature is 80 DEG C.The grinding wheel of technical solution of the present invention production is when in use, since its density is gradually incremented by from outside to inside, with the reduction of outer diameter, but due to the increasing of density, the abrasive particle number for participating in grinding is increased, effectively stock removal is compensated, greatly improves grinding efficiency, extends the service life of grinding wheel.Simultaneously as grinding wheel density is gradually incremented by from outside to inside, the mechanical strength of grinding wheel promotes 10% or more.
Description
Technical field
The present invention relates to a kind of resin grinding wheels, are specifically related to a kind of resin fine grinding for making stock removal and compensating automatically
Abrasive wheel forming method.
Background technique
The grinding wheel that resin wheel is made of resinoid bond and abrasive material, since resin is a kind of organic bond, manufacture
Wheel strength it is high, there is certain elasticity, heat resistance is low, and self-sharpening is good, and simple for production, process cycle is short, is widely used in thick
It mill, snagging, cutting and is freely ground.With the development of grinding wheel manufacturing technology, more and more accurate grindings use resin wheel,
The resin wheel of Ultra-fine can be mainly made of resinoid bond, and vitrified bond is made super by its properties affect
It can a large amount of cracked waste products when fine granularity grinding wheel.It is well known that the speed of mainshaft of the equipment for grinding such as lathe, grinding machine is usually solid
Fixed, when grinding wheel uses at the beginning, its outer diameter is larger, and the abrasive grain for participating in grinding is more, grinding efficiency and ground effect all compared with
It is good；With the use of grinding wheel, consumption, outer diameter is smaller and smaller, and the abrasive grain for participating in grinding is fewer and fewer, and grinding efficiency is reduced, ground
Requirement cannot be reached by cutting effect.Therefore, resource can only be caused in grinding wheel there are also being replaced in the case where larger outer diameter
Waste, while also improving use cost.
Summary of the invention
It is mentioned immediately above in order to solve the problems, such as, stock removal, grinding can be compensated automatically the purpose of the present invention is to provide a kind of
High-efficient, grinding wheel resin grinding wheel shaping method with long service life.
The technical scheme is that a kind of resin grinding wheel shaping method that stock removal compensates automatically, including mixing,
Molding, solidification, manufacturing procedure the improvement is that molding procedure, will using the cover half compression moulding on abrasive wheel forming unit
Mould circle, plug are fixed on the rotating-table apparatus of abrasive wheel forming unit, are put into lower template, start turntable, by load weighted molding mass
The centre of mould circle and plug is uniformly put into, material is pulled when feeding intake, it, will be at dedicated material scraper after whole molding mass are put into
The upper surface of moulding mixture spreads to 2~5 ° outer low and inner high of inclined-plane, covers cope plate, is suppressed using half heat pressing process, pressure
Pressing pressure and press temperature technological parameter are as follows:
After release, takes out grinding wheel blank and solidified again, processed.
The invention adopts the above technical scheme, in scraper that the charge level at plug is higher than outer ring charge level, due to upper and lower
Template is all plane, and grinding wheel blank is formed after compacting, and density is gradually incremented by from outside to inside；Half heat pressing process, control are used simultaneously
It makes each step-up temperature, keep the temperature the pressing pressure of speed and each stage, to ensure that tall stupefied waste product will not occur for grinding wheel.It is this
Method production grinding wheel when in use, since its density is gradually incremented by from outside to inside, although with the reduction of outer diameter, effectively be ground
Area becomes smaller, but due to the increasing of density, the abrasive particle number for participating in grinding is increased, effectively compensated stock removal,
Grinding efficiency is greatly improved, the service life of grinding wheel is extended.And the angle due to controlling inclined-plane, so that grinding wheel
Integral hardness controls within the scope of half small grade, does not influence the ground effect of grinding wheel.Simultaneously as grinding wheel density from outside to inside by
Step is incremented by, and the mechanical strength of grinding wheel promotes 10% or more.
Specific embodiment
Production 1-600*75*305-WA/F320K7B2-50m/s resin grinding wheel 50, by formula mixing, by above-mentioned
Method, technological parameter progress half are hot-forming, and the gradient on the inclined-plane is 3 °, obtain after cured, processing.Through detecting, grinding wheel
Inside and outside difference of hardness be 0.3 small grade, mechanical strength reach 60m/s.Used through domestic multiple producers, grinding efficiency improve 20% with
On, service life improves 50% or more, is better than similar product.
Claims (1)
1. a kind of resin grinding wheel shaping method that stock removal compensates automatically, including material mixing, molding, solidification, manufacturing procedure,
