Description
Technical field
The present invention relates to a kind of spiral complex-curved viscoplasticity abrasive flow finishing method and device, belong to plant equipment field.
Background technology
Spiral camber is a kind of complex-curved, and complex structure, the cost of complex-curved class part process equipment are high, and its surface polishing technique has become a large focus in Precision Machining field.Wherein, screw rod is a kind of workpiece typically with spiral camber.In recent years, the application of screw rod in air compressor machine, refrigerator, industrial pump, plastics machinery is more and more extensive.Screw rod is plastics machinery " heart " parts, and the height of its quality directly has influence on the quality of service life of a machine and moulded products.How to process high-quality screw rod, make it reach designing requirement, become the manufacturing important topic of domestic and international plastics machinery.
The typical process of plastic mechanical screw is at present: the grinding → polishing of forging stock → turning → rough milling → heat treatment (quenching) → cylindricalo grinding → numerical-control screw rod.Wherein, polishing process is last procedure that screw rod is manufactured, and object is to realize reducing screw surface roughness, minimizing helical surface manufacturing deficiency and residual stress, ensures that screw surface quality reaches design and use requirement.Because the height of screw surface quality directly affects the service life of molding machine and the quality of moulded products, therefore screw rod glossing is more and more subject to the attention of manufacturer.But screw spiral curved surface is that one is typically complex-curved, is difficult to realize the automation of process.Current middle-size and small-size screw rod manufacturing enterprise adopts abrasive band polishing and hand-polished mode to complete.Wherein, abrasive band polishing needs special lathe, easily produces dust in polishing process, and the easy loss in abrasive band, and processing cost is high; Manual polishing, labour intensity is large, poor working environment, its crudy is directly subject to the impact of workman's skills involved in the labour, and technology stability and uniformity are poor, are difficult to meet the instructions for use of precise plastic machinery.
Day by day fierce along with improving constantly of requiring of screw rod properties of product and market competition, superseded low and middle-grade times of requirement manufacturing enterprise, the product that precision is poor, added value of product is lower, promote intensive processing level, more new technology and equipment, the high added value screw rod product that Development and Production is new.
Also there is no at present polishing technology and the equipment for the complex-curved processing characteristic of spiral.Therefore, in the urgent need to a kind of new automation polishing technology, to realize complex-curved efficient, the high uniformity of spiral, polishing cheaply.
Summary of the invention
For the problem that in the complex-curved polishing process of current spiral, polishing effect is poor, cost is high, the present invention proposes a kind of working ability is strong, efficiency is high, cost is low, the spiral of high-efficiency environment friendly is complex-curved finishing method and
Device.
The complex-curved viscoplasticity abrasive flow of a kind of spiral burnishing device, comprise processed screw rod, abrasive material, seal box, fixed mould, gap and spiro driving device, described processed screw rod one end is connected with spiro driving device, the other end immerses in abrasive material, spiro driving device is arranged on seal box top, fixed mould is arranged on seal box inside by pole, and abrasive material is viscoplasticity abrasive material, and fixed mould is cannulated mould.
Described abrasive material adds fine abrasive particle to form viscoplasticity abrasive material by full-bodied solution, mixed liquor.
Described fixed mould length is greater than the length of the helicoid of processed screw rod, and the helicoid position of processed screw rod is setting in the centre position of fixed mould.
Between described fixed mould and processed screw rod, there is the machining gap of 0.1-5mm.
Middle part, described fixed mould below is provided with scroll positioning piece, for the processed screw rod that is located by connecting.
Full-bodied solution, mixed liquor can be mixed by polyethylene glycol oxide, silicone oil, NaOH etc., also can be by compositions such as aviation kerosine, silica gel, triethanolamines.
Fine abrasive is following one or more mixtures: diamond, cubic boron nitride, carborundum, aluminium oxide, cerium oxide, silica, zirconia etc.
Add man-hour, processed screw rod drives High Rotation Speed by spiro driving device, and in the time of screw rod High Rotation Speed, abrasive material moves the spiral grooves along screw rod upward, the direct high speed polishing workpiece to be machined of abrasive material being transmitted.In order to make the constantly do action and reusing of abrasive material in processing, therefore fixed mould is designed to a hollow mould.Actual while carrying out polishing, because abrasive material is closed in body, so do not have and leak, constantly repetitive cycling is used, and in the time that screw rod High Rotation Speed drives abrasive material screw, abrasive material can simultaneously push processed screw surface, one side is carried out high-speed screw rotation, because abrasive material is a kind of smart micro-machined viscoplasticity abrasive material that is applicable to, in the time that abrasive material rapid spiral rotates by screw surface, can carry out denier polishing to screw surface; And by the abrasive material of screw rod, reaching cannot be upwards soaring again behind mould top, be just pushed to side and flow by thing followed abrasive material; When abrasive material is away from the screw rod in rotating, the upwards support force that screw rod provides just reduces greatly, and now because the impact of gravity starts to whereabouts, so periodically motion completes the object recycling.The movement travel of helical polishing is long compared with the stroke of conventional reciprocating formula abrasive flow polishing, can make helical surface obtain uniform polishing action.Because the abrasive material in burnishing device has the function circulating, viscoplasticity abrasive material cost is low and consumption is few, has low cost, high efficiency, can remove the function such as burr, metamorphic layer, reaches the processing effect of work piece fast polishing.
The invention has the beneficial effects as follows: 1. because the course of work of this polishing processing and screw rod is similar, can make processing effect more meet the need of work of screw rod, therefore this finishing method can be realized the polishing of this complicated surface of helical surface and ensure building motion without complicated high precision machine tool.2. do not need the lathe of high accuracy and high rigidity, there is no the problems such as rigidity, precision, vibration or the vibration of traditional precision equipment.Between abrasive material and surface of the work and non-rigid contact, so even if having the large abrasive particle of minority to exist or inhomogeneous hard point accidentally appears in surface of the work, also can not scratch surface of the work because of cutting force flip-flop.3. viscoplasticity abrasive material has viscosity variation effect, is extremely applicable to essence and throws, and polish pressure is evenly distributed, so workpiece can not be out of shape and excessive cutting.4. spiral abrasive flow burnishing device can be set up on common or Digit Control Machine Tool (lathe, milling machine), and interchangeability is high, can reach comprehensive automation, saves equipment investment, meets economic benefit.5. abrasive material is reusable and consumption is little, operating maintenance is easy, cost is low, productivity ratio is high.Therefore, this polishing technology has good realizability, can realize screw rod high efficiency, high-quality and high conforming polishing.
