Description
Technical field
The present invention relates to the slide fastener technical field, refer in particular to a kind of technology of utilizing the differential spirally-wound principle that metal slide fastener surface is carried out minute surface polishing, grinding, polishing, the special equipment of accomplishing this technology is provided simultaneously.
Background technology
At present domestic slide fastener is carried out polishing is to adopt the wire wheel polishing technology, and wire wheel rotates at a high speed, drive the wire wheel polish brush and contact with slide fastener point, and the realization grinding, the problem of its existence is many.
1. wire wheel polishing technology; Its polishing principles is to be slide fastener surface scratch brushing and deburring, because it is not to work with the mode of removing material, therefore can't accomplish the complete light face of slide fastener surface at all; Though the slide fastener surface burr amount after the polishing reduces; But its surface smoothness is still very coarse, can't remove the trace that draws that stays behind the metal zip fastener stamping-out, and the surplus that causes slide fastener to retain originally can't be removed.In order to solve this drawback, equipment producer has increased by one calendering on every equipment, utilizes 2-4 roll, and slide fastener is pressed onto size and pull head cooperation, could normally use.
The major reason that the manufactured goods surface roughness Ra value of polishing with wire wheel can't improve is that the steel wire of wire wheel can't accomplish superfine, and the thinnest steel wire is 0.10mm at present, and so thin wire wheel price is very high; Not only fracture of wire causes slide fastener can not cross needle checking machine easily; And the degree of wear is very fast, even like this, the slide fastener surface cut that it can polish out also only is about 0.10mm; And the slide fastener surface that it is inswept is diffuse reflection; Light reflection directly perceived is laxed, and optically focused not can't reach the effect of light face, minute surface at all.
2. the key equipment in the wire wheel polishing technology is the wire wheel polish brush; Its fracture of wire very easily in polishing process, the wire that causes fractureing is mixed in the ribbon of slide fastener, makes slide fastener or clothes when making the article check, can't cross the inspection pin; The fracture of wire diameter is generally between 0.12-0.20mm; Length does not wait at 5mm-12mm, and the consumer is caused great potential safety hazard, particularly children's garment.
In order to pursue polishing effect and brightness; Usually the wire wheel rotating speed is set to 2800RPM-4000RPM, almost surpasses the limit line speed of wire wheel safe handling, because the five equilibrium uniformity of wire wheel circumferencial direction steel wire quantity can't be accomplished by wire wheel manufacturer; Therefore almost the neither one wire wheel does not exist centrifugal force and circle to beat; Under high speed rotating, the jerk value of wire wheel has directly been buried potential safety hazard, has also increased the noise of equipment; Reduced the life-span of bearing, more serious is run up can cause down reeling off raw silk from cocoons, the phenomenon of running.
In addition, on material, develop from those early years ordinary steel wire always and to upgrade to high-carbon steel steel wire, stainless steel steel wire, coppered steel wire; Even developed into utilization import piano wire, but still satisfied not the needs that continuous polishing is produced, the external diameter of wire wheel is under the friction of high speed rotation and slide fastener; Constantly dwindle, cause the operative employee will often remove to estimate wire wheel and whether touch slide fastener, if do not touch; Then to adjust immediately, and find not that sometimes then the defective products slide fastener then creates continually; Controllability is low, has directly caused the instability of product quality and the increase of rework cost.
3. in order to prolong the service life of wire wheel, improve polishing brightness and effect directly perceived, constantly increasing the wire wheel quantity of a machine in recent years; From 4 wire wheels the earliest, be increased to 10 of today, 12 wire wheels always; Not only equipment price is very high; Difficult in maintenance, more serious is, and to cause a slide fastener in equipment, to twine the girth of turnover oversize, causes exporting the active pulling force excess load of drive; In order to improve this situation, equipment has increased the power of motor, and the result has caused slide fastener fracture easily in equipment again, ruptures more easily because its pulling force has surpassed the tensile strength, particularly joint of slide fastener itself.Each fracture; The operative employee wears the band leader tape again often will spend the plenty of time; As the slide fastener that runs into fracture involved in the equipment revolving part, not only has potential safety hazard, also causes fault power time oversize; Incur loss through delay the delivery date that can not expect that has directly influenced the slide fastener product, and the significantly improving of manufacturing cost.
4. polish brush is in manufacture process, and it all has one deck lubricant grease above steel wire, intensive in wire wheel, changes new wire wheel at every turn, and equipment one gets into smooth, and grease is write freely and easily out, cause zipper strap particularly the strap of light colour by oil pollution.
5. in recent years, along with consumer and client's aesthetic conceptions, quality requirements progressively promotes, zipper fabrication producer suffers from does not have new technical equipment to emerge; When running into the product of having relatively high expectations, usually slide fastener is repeated to polish 5-6 time, hope to reach the effect of import brand slide fastener; Though the slide fastener surface effect increases, owing to repeat friction, zipper cloth belt has the phenomenon of generally fluffing and dirty band; Finally still fail to reach requirement of client, particularly exported product.
External slide fastener polishing technology, in order to pursue the fineness of slide fastener miaow tooth, employing be miaow tooth particle vibropolish; Be assembled into one by one on the ribbon with special equipment after the polishing, CT Cycle Time is very long again, and production link is complicated; Quality control point distributes wider; Yield rate is lower, and efficient is extremely low, causes manufacturing cost very high.
Summary of the invention
The present invention is just in order to overcome above-mentioned deficiency; A kind of differential spirally-wound type metal zip fastener mirror-polishing process is provided; The chain code that closes to metal zip fasteners such as copper, aluminium, stainless irons is adorned; Carry out mirror finish to one-shot forming, make metal zip fastener obtain the surface quality of high accuracy, best bright finish, solved professional difficult problems such as metal zip fastener tradition glossing polishing effect is not obvious, efficient is low, system loss rate height.Main innovation is that with the differential spirally-wound device be core; Be aided with the flexible abrasive material sand belt; Handle metal slide fastener surface through differential spirally-wound along throwing principle; Promptly to be the processing mode of removing material with grinding process crude, uneven of metal zip fastener, stamping-out cutter trade surface, not only improved the thickness residual that surface accuracy has also been eliminated slide fastener.
Specifically implement like this: differential spirally-wound type metal zip fastener mirror-polishing process; It is characterized in that the chain tooth surface of metal zip fastener is contacted with flexible grinding band formation face; Slide fastener and flexible grinding band with at the uniform velocity or speed change advance; Slide fastener and flexible grinding interband form along the speed difference that advances, and the crude top layer of slide fastener is removed by the cutting of flexible grinding band.
The surface attachment of flexible grinding band is useful on the grit of cutting.Select suitable abrasive material sand belt customized respectively for use according to the material of processed slide fastener, select for use the sand belt of suitable granularity to carry out thick fine finishining according to the blank roughness of processed slide fastener.The sand belt granularity that is specially adapted to above burnishing parameters commonly used has 100#, 120#, 180#, 320#, 400#, 600#, rationally selects for use according to the slide fastener crude green body of the crude degree of difference.Quality to the flexible grinding band is selected for use, be to its abrasive material (corundum. carbon silicon), granularity (thickness 46---1200#), conjugation (soft or hard H-I-J-K-L), tissue (pore 5.6.7.8), bond (pottery. resin. rubber etc.) these characteristics stipulate.
Consider that from practicality the flexible grinding band is installed ringwise, the linear velocity that the high speed circular motion forms more helps improving cuts nitre efficient.
Each the free drive assembly of action of advancing of slide fastener and flexible grinding band is accomplished in this technology; The slide fastener gait of march be 900-2200 rice/hour; Optimum speed 1000-1500 rice/hour, the velocity ratio of slide fastener and flexible grinding band is 1:150-800, optimum speed is than being 1:300-600.Through the ratio of governing speed difference, can accomplish corase grind and correct grinding.
In order to accomplish the polissoir of above-mentioned differential spirally-wound type metal zip fastener mirror-polishing process; Sand belt polishing unit by a group or more is formed; The structure of sand belt polishing unit is: sand belt is provided with one or several polishing points, and each polishing is o'clock spacing by two position-limited wheels, and position-limited wheel is fixed on the crossbeam two ends of T shape push rod; Be used to keep polishing the positional stability of sand belt in the zone; T shape push rod is installed on the fixing adjustment seat, is close to the upper surface or the lower surface of sand belt at polishing point place by the slide fastener of transition guide wheel group support, and slide fastener is connected slide fastener drive assembly and sand belt drive assembly respectively with sand belt.
This polissoir is through design 1 or many sand belts; Several polishing points of design on every sand belt; Slide fastener can form the strip winding mode of different modes between the polishing point of sand belt under the guiding of guide wheel, realize that the single face of slide fastener, two-sided stock removal polishing are to finished product.For example: polishing both surfaces, polish unit combination by four groups of sand belts, 2 sand belts are thrown the front, and 2 sand belts are thrown reverse side, and are respectively smart throwings of a thick throwing.Accomplish ultra lappingout if any customer requirement, glossing just is formulated to thick the throwing with half essence of first pass and throws second time smart throwing and ultra lappingout so.It is just passable only to need to change thinner sand belt for second time, and also can be headtotail when throwing second time, throws for second time to connect leader tape again after good, wait the head of leader tape to come out after, cut off, just finished the work.
