Description
Technical field
A kind of detachable soldering locking nub emery wheel, belongs to super hard abrasive instrument manufacturing field.
Background technology
Soldering super-abrasive grinding wheel can be used for the materials such as grey cast-iron, spheroidal graphite cast-iron, plastics, nylon, rubber, stone material, steel
The surface grinding of material.The grinding of usual above-mentioned material uses Conventional abrasives more（Corundum wheel or carborundum）Emery wheel, profit
It is installed on when resinoid bond or vitrified bond hot pressing consolidation preparation, use beneficial to Internal hole positioning on abrasive machine.Due to pricker
Weldering super hard abrasive instrument relative to corundum wheel and plating super-abrasive grinding wheel there is abrasive material to hold intensity height, abrasive material exposure
Height, grinding is sharp, the advantages that radiating efficiency is high, and abrasive material is difficult for drop-off, and no dust is vaporized, the mill applied to above-mentioned material field
It is whittled into as preferably selection.
But for soldering emery wheel, mostly one-piece base body, then soldering super hard abrasive preparation.The superhard emery wheel of current soldering
Problems be present in the surface grinding applied to materials such as grey cast-iron, spheroidal graphite cast-iron, plastics, nylon, rubber, stone material, steels：
（1）Due to super hard abrasive solder could be prepared in steel matrix by high-temperature heating, therefore the base of soldering emery wheel
The internal stress of body is not easy to discharge, and certain deformation easily be present in welding, for discoid grinding wheel base body,
Deformation is not only present in circumferencial direction, is also present in disk direction.Machining accuracy during this deformation effect emery wheel rapidoprint
（The accuracies of form and position such as circularity, flatness, rotating accuracy）, it is unfavorable for installing.And this precision is difficult to be adjusted by dynamic balancing.If
Unreasonable installation and use, easily cause certain danger.
（2）Abrasive wheel substrate is mostly steel matrix, and quality is big, most weight of emery wheel instrument is occupied, to plant capacity
It is it is required that higher.Conventional emery wheel is corundum wheel, its density about 2.5 ~ 3g/cm3Left and right, far below 7.9 g/cm of steel3.Therefore
The plant capacity for matching the lathe of conventional emery wheel does not reach the adaptation detachable soldering locking nub emery wheel requirement of soldering, removable to soldering
The application for unloading formula soldering locking nub emery wheel has considerable influence.And on steel matrix surface by processing the modes such as lightening hole, material removal
Can be got up partial action, but because the density of steel is about 2.5 ~ 3 times of emery wheel density, can not fundamentally mitigate the weight of emery wheel
Amount, and the material that loss of weight removes is the more, and loss of weight hole number is bigger with aperture, higher to the rigid requirements of emery wheel, adds survey
Examination and the difficulty and number of l-G simulation test, are unfavorable for the control and product development of cost.
（3）When emery wheel specification is larger, such as more than external diameter 300mm, the detachable soldering locking nub emery wheel of soldering is entered completely
Row soldering is heated, higher to vacuum brazing furnace space requirement, between vacuum drying oven effective heating area width at least above more than 400mm,
Heating soldering could be preferably carried out, and vacuum furnace inner space is limited, heat time length, if single furnaceman's part is less, to be unfavorable for
Production efficiency is improved, and largely effects on the production cost of detachable soldering locking nub emery wheel.
（4）Because Conventional abrasives emery wheel is using the preparation of hot pressing consolidation technique, bonding agent is mostly resin or vitrified bond, is ground
Emery wheel has certain elasticity when cutting, and can reduce impact rigidity of the emery wheel to workpiece surface, the vibration one of emery wheel when making grinding
Determine degree reduction.And soldering super-abrasive grinding wheel is because matrix is steel, the firm soldering of super hard abrasive, with workpiece surface Grinding Contact
When be rigid contact, the out-of-flatness of workpiece surface is easily conducted to lathe, cause grinding vibrate, influence to be ground.Additionally due to just
Property grinding, easily superabrasive surface landforms are resulted in blockage when the amount of feeding is big, although super hard abrasive radiating efficiency is high, chip removal
It is good, but because abrasive material is not fallen off, abrasive dust caused by moment is possible to block part region surface, causes temperatures at localized regions drastically
Rise, be damaged abrasive material high temperature oxidation herein, grinding workpiece surface causes grinding burn.In this case, soldering is detachable
The grinding life-span of formula soldering locking nub emery wheel can not be guaranteed, and increase unpredictability.
Corresponding with the detachable soldering locking nub emery wheel of soldering is the detachable soldering locking nub emery wheel of plating, due to galvanizer
For skill without high-temperature heating, the stress of matrix is small, can be by the way that matrix material partial replacement, and overall plating are reached into higher
Assembly precision and efficiency, and the detachable soldering locking nub emery wheel of soldering is then difficult to reach this effect.But from application efficiency and sexual valence
From the point of view of than on, detachable its grinding performance of soldering locking nub emery wheel of soldering is better than electroplating technology.Using soldering super hard abrasive technique
Emery wheel it is more advantageous.
Patent（CN200710132643- super-abrasive grinding wheels）By the way that the grinding area of emery wheel is used into multi-block type system
Standby, grinding wheel base body does not have into stove heat, and this mode causes soldering heating part to reduce, and is advantageous to soldering preparation, but in order to ensure
It is complicated radially with the fixation of circumference, and without loss of weight measure, be not suitable for being applied to replace Conventional abrasives emery wheel superhard with electroplating
Abrasive grinding wheel.
Patent（A kind of combined type brazing super-abrasive grinding wheel matrixes suitable for superhigh speed grinding of CN201010514158）
Also utility model a kind of knockdown grinding wheel base body, this matrix fixes locking nub emery wheel locking nub beneficial to two covering plate structures, and
Compressed using screw thread.Designed locking nub is complicated, and dimension precision requirement is higher, therefore suitable for superhigh speed grinding processing,
Can not effectively it be substituted for conventional wheel grinding.
Therefore to be preferably beneficial to the advantage of soldering processes, replacement Conventional abrasives emery wheel and plating super-abrasive grinding wheel,
Need a kind of new wheel structure, by wheel structure is simple, light weight, be easy to soldering heating, grinding efficiency height is not easy to burn
Some is organically combined.Effective application of emery wheel involved by the utility model, can not only reduce powder caused by conventional emery wheel
Dirt, gaseous contamination and grinding efficiency, production efficiency can be improved, be advantageous to the upgrading of national equipment manufacture and green plus
Work develops.
