Description
1, technical field:
The present invention is a kind of pair of efficient mirror finish device of bistrique and bright finished process thereof, belongs to the innovative technology of mirror finish device and mirror-polishing process method thereof.
2, background technology:
There is a large amount of cylindrical mirror finish work in the industrial production, as: various minute surface roll, auxilliary moving sleeve, all kinds of axle part, container conduit etc.General big-and-middle-sized cylindrical mirror finish is all through following 3 classes, 7 procedures: blank → rough turn → half finish turning → finish turning → half correct grinding → correct grinding → mirror finish etc.; Relate to 3 kinds of equipment: lathe, grinding machine, mirror finish special equipment etc.; Workpiece clamping and logistics through 3 times from the blank to the finished product transported; Three kind equipments (especially grinding machine and mirror finish special plane) fixed investment itself is big, needs to use more operator, takies more place and space.
The precision mirror surface polishing technology method of cylindrical mainly contains at present: the processing of oilstone polishing, and open type diamond lap band ultrasonic vibration mirror finish, electrochemical machinery composite polishing etc., but all have such-and-such shortcoming or deficiency:
Oilstone polishing processing needs special equipment, the initial roughness before polishing is required low, must reach below the Ra0.4 μ m, and oilstone belongs to bonded abrasive tool, and quality is bigger, and efficient is lower, and what have applies vibration, but that frequency is difficult for reaching is higher; Need cooling fluid and corresponding circulated filter system.
Open type diamond lap band ultrasonic vibration polishing, not only require initial roughness low, need complicated huge special equipment, and since open type grind band unwinding and rewinding speed objectively can not be higher and same efficient is not ideal too, and diamond lap band cost is higher, needs cooling fluid and circulated filter system.
Though electrochemical machinery efficient is higher, original Ra is same less demanding in 0.8 μ m.Professional equipment needs the large power supply and the complicated electrolyte filtering circulatory system, electrolyte contamination workpiece and operating environment, and health risk, the workpiece post processing is cumbersome, and the processing of waste and old electrolyte is a problem.
Above-mentioned mirror finish method not only has higher requirement to initial roughness, operation is many, equipment is many, transhipment often, need the operator many, and all need special equipment than complex and expensive, efficient is lower, and all be non-dry type processing, the subsequent treatment of need complexity.
3, summary of the invention:
The objective of the invention is to overcome above-mentioned shortcoming and provide a kind of simple in structure, the efficient mirror finish device of two bistriques that working (machining) efficiency is high.
Another object of the present invention is to provide a kind of dry-type processing that is, do not need the bright finished process of complicated subsequent treatment.

The efficient mirror finish device of the two bistriques of the present invention adopts the structure of polishing abrasive band as the rubbing down tool, and the present invention can carry out bright finished process with this device on lathe, and therefore, it compared with prior art has following purpose advantage:
1. fixed investment is few, makes about 3000 yuan of the two grinding head devices of a cover, and by contrast, grinding machine and mirror finish special plane are hundreds thousand of at least.
2. be easy to implement, time is few, and versatility is good, and bistrique is as the installation of lathe tool, and the replacing adjustment in abrasive band is also easier lathe tool than installation one, and is not high to workman's specification requirement.All general to the medium-and-large-sized lathe more than the C616, little lathe must be according to same principle specialized designs separately.
3. safe, both just having ruptured to cut off in the abrasive band does not have the hidden danger of hurting sb.'s feelings, hindering equipment yet,
4. it is precise polished to change the wet-milling of original emery wheel, oilstone, dry type grinding that wet type is finished to the abrasive band and dry type correct grinding, does not use expensive superhard abrasive material grinding tool such as diamond and CBN, reduces the instrument cost, improves exploitativeness and practicality.And wheel grinding needs dynamic balancing and correction of the flank shape in time to keep sharp, and the abrasive band only need be changed, and quick-change mechanism can guarantee efficiently to carry out fast; The thick fine ginding in abrasive band, polishing are entirely changed different abrasive bands and are carried out on a cover polishing head device, and emery wheel needs the grinding machine of different accuracy grade and different emery wheel types; And the consumption of the no grinding fluid of dry grinding, the many convenience that can avoid grinding fluid and polishing fluid to bring; Produce in enormous quantities in conventional abrasive band, and in liberal supply, the hyperfine abrasive band use cost that mirror finish is used is about about 1/20 of diamond lap band.
5. adopt two bistriques can accomplish the thick fine finishining concurrent working of grinding and polishing, the abrasive band belongs to coated abrasive tool, and enclosed abrasive band speed can be up to 40m/s, the characteristics of coated abrasive tool electrostatic sand-planting manufacturing process self guarantee that it is sharp and do not block, significantly improve grinding and mirror finish efficient, cut down finished cost, the efficient of conventional sbrasive belt grinding is more than 4 times of wheel grinding, bright finished efficient and electrochemical machinery are suitable, being more than 20 times of oilstone polishing, is more than 5 times of polishing of diamond lap band vibration.The abrasive band abrasive grain of Shi Yonging is from 36#～800# simultaneously, for the mirror finish of low roughness provides objective base;
6. grinding force is little, and heating is few, the workpiece of also not burning of dry grinding, and grinding force is little little to cylindrical shell generation distortion, and precision stability is good, the mirror effect that obtainable minimum Ra value is 0.018 μ m, crudy is good.But non-ferrous metals such as grinding copper aluminium do not block yet and hold the chip removal space, and machining accuracy depends on the front turning process,
7. the range of work and application prospect are extremely wide, and it is because the institutional framework of material self is limited that the cylindrical part of nearly all metal and most nonmetallic materials, the material that has can not be worked into minute surface.
8). adopt two bistriques to accomplish the thick fine finishining concurrent working of grinding and polishing, the abrasive band belongs to coated abrasive tool, and enclosed abrasive band speed can be up to 40m/s, solve the inefficiency problem of additive method, significantly improve grinding and mirror finish efficient, cut down finished cost, the abrasive band abrasive grain of Shi Yonging is from 36#～800# simultaneously, for the mirror finish of low roughness provides objective base.
The two efficient mirror finish device of the bistrique versatilities of the present invention are good, rationally distributed, compact conformation, easy to operate, with low cost, security is good.The two efficient mirror finish devices of bistrique of the present invention can be installed on the dissimilar lathes, make lathe have the grinding machine function, and the function multiplication after bistrique is removed, does not influence original lathe function at all.Process of the present invention belongs to dry type glossing pure mechanical system, that do not need subsequent treatment, does not use any cutting fluid or polishing fluid, does not also just need corresponding circulated filter system.Process of the present invention makes workpiece once can finish rough turn, finish turning, half finish turning, half correct grinding, correct grinding and mirror finish etc. on the lathe behind the clamping, reduced the equipment input, operating personnel have been reduced, reduced the work-yard, reduced workpiece transhipment and clamping times, the operation that solves original method is many, equipment is many, personnel are many, the place take many, workpiece transport more than and clamping workpiece wait " more than 6 " problem often.
