To make cold roll the whorl size that approachs treatment accurate, stable, put forward to rolling the diametical dimension of filar preform relatively high accuracy requirement. Accordingly, cold to needing for the most part roll the preform diameter that presses treatment whorl to all need to undertake accurate turning or grinding are machined, boil otherwise make the whorl dimension precision that go out low, quality is not stable, and cold boil press treatment process to be controlled not easily, it is more difficult also that the machine tool is adjusted, still can squeeze bad sometimes roll filar annulus, lower the working life of tool and machine tool. Use cold boil press coincide of old way of whorl and turning whorl to machine craft, criterion but better solve afore-mentioned problems. Graph 1 need to roll the part of hollow Bao Bi that controls treatment 1 craft principle and characteristic are cold rolling the principle that presses coincide of old way of treatment whorl and turning whorl to machine craft is boil in common machine tool rolling silk when pressing treatment whorl, do not use the guide plate that prop up to support work, use core axis to support hollow work however inside aperture, or the form that prop up props up the upside that uses other type to be boiled to approach work. The position that supports guide plate formerly in workpiece bottom installs lathe tool of figuration of plane of a wide blade, the whorl old way that in will rolling filar process at any time, this lathe tool can form exceeds the turning of spare part metal that the standard asks to drop. Because process of this one treatment is boiling,press treatment to form whorl tooth model while old to whorl way undertakes turning is machined, because this is called cold boil press treatment of coincide of old way of treatment whorl and turning whorl. This craft and roll the craft appearance that controls treatment whorl to compare alone formerly, increased to use the process of old way of whorl of turning of figuration lathe tool. In because boiling,controlling whorl process, can control dimension of whorl old way through adjusting lathe tool position, when because this boils,pressing whorl, ask to the dimension precision of preform but need not boil like convention pressure whorl craft is strict in that way, diameter of original preform rolling silk must make sure through finish machining ability working procedure rolling silk asks, and when using coincide to machine craft, preform diameter simply can satisfy a requirement through rough machining (dimension of diameter of the preform before needing to will roll silk only increases 0 ～ a bit 0.

3mm) , precision asks but from make an appointment with IT9 class to reduce to IT12 class. Be like the tape spool shoulder that the graph shows 1 times spare parts of hollow Bao Bi, machine the preform diameter D0=25 that whorl needs actually.

95-0.

06mm, after using coincide of old way of whorl of turning rolling silk to machine craft, practical technology measure is D0=26.

23-0.

28mm. Coincide of old way of whorl of turning rolling silk machines craft to have the following characteristic: The dimension of whorl old way of treatment is accurate, stable; The whorl tooth tip that gains after treatment shows echelon, adjacent and academic tooth the tooth supports; Ask to reduce to rolling the precision of dimension of diameter of the preform before silk, reduced finish machining process, reduced production difficulty, the sources of energy to use up with finished cost; The use that enlarged common machine tool rolling silk adjusts range, realized one machine much can, rose to machine benefit. 2 technology unit pursues 2 to machine tape spool shoulder the coincide of old way of whorl of turning rolling silk of spare parts of hollow Bao Bi machines device sketch map. 1.

Bolt of cutting tool close solid pursues spare partses of 2 hollow Bao Bi roll coincide of old way of filar turning whorl to machine device to boil pressing whorl device to roll coincide of old way of filar turning whorl to process technology unit is change his costume or dress on common machine tool rolling silk and become, its structure is simple, change one's costume or dress convenient, workload is not big. The part rolling silk of this device still maintains primary machine tool to roll the basic structure that controls whorl share, namely by gyro wheel of fixed gyro wheel and activity two parts are comprised. Fixed gyro wheel is to show installation is rolling what filar machine tool secures main shaft to go up to roll filar annulus, boil when pressing whorl, it makes whirligig only; Mobile gyro wheel is to show installation is in those who roll main shaft of activity of filar machine tool to go up to roll filar annulus, boil when pressing whorl, it divides whirligig outside, still procrastinate as the activity of the machine tool board (drive in cam or hydraulic pressure oil cylinder below) make perpendicular the feed at axes direction, regressive or intermittent motion. When feed of towards the left of mobile gyro wheel, undertake boiling pressing machining to workpiece; Right when go back and cease, can assemble and unassemble workpiece. Bearing part rolls what coincide of old way of filar turning whorl processes technology unit to go up on bearing part basically comprises bearing core the spare parts such as axis, bearing support, eccentric shafe and bearing (2) seeing a picture. Bearing part is on change on primary machine tool rolling silk make assemble and become. Boil when pressing whorl, the core axis installation that is used at bearing workpiece is in bearing support is lower two only kinds inside aperture of tapered roller bearing, in order to ensure core axis is rotational and agile. Bearing of bearing core axis is hollow thin wall spare parts, use at determining the centre height of the spare parts and axial position. The upside of bearing support secures the link that rolling filar machine tool with eccentric shafe of a square head board on. Bearing support and square head eccentric shafe are used slip cooperate to be assembled together, bearing support is the centre of a circle with square head eccentric shafe, can realize freedom to swing. Through adjusting the axes position of square head eccentric shafe, can adjust the centre height of axis of core of bearing of bottom of bearing support along with, adjust the centre height that is boiled to control a part then. Turning device is shown 2 times like the graph, while to hollow Bao Bi the spare parts undertakes silk is machined boiling, by the wide blade lathe tool on turning device old to whorl way is undertaken turning is machined. Turning device tightens solid bolt, cutting tool to adjust the composition such as bolt by tool carrier body, lathe tool, cutting tool, installation is rolling the base position of guide plate of former bearing of filar machine tool. Boil to suit press turning the whorl spare parts of different specifications, obtain size of exact whorl old way, the lathe tool distance to work center line is adjustable. When adjusting lathe tool to be apart from, loosen cutting tool tightens solid screw above all, pigheaded move embed the T form inside lathe tool body to adjust bolt, can make plain top lathe tool rises or drop, change the blade distance to work center line, control dimension of workpiece whorl old way thereby. The base position of the machine tool rolling silk that takes tool carrier put oneself in another's position can be controlled adjust, be apart from H in order to make with work center the line maintains a level before plain top lathe tool, obtain G of the horn before lathe tool thereby. Before 3 operations should choose treatment, answer above all the basis is machined the whorl norms of spare parts of hollow Bao Bi, roll place of make choice of of the concerned parameter such as size of aperture of the length that controls whorl share, spare parts and treatment requirement to need roll lathe tool of axis of core of filar annulus, bearing, plain top and whorl to measure a tool to wait, adjust a requirement by installation correct installation rolls lathe tool of mouth of peace of axis of core of filar annulus, bearing. Choose those who roll filar machine tool to boil according to workpiece characteristic and treatment requirement next pressure speed of rotate speed of dosage, main shaft, feed and boil press total cycle time to wait. Open motive bed, it is normal that examination machine tool runs partly each, make the machine tool enters automatic loop to machine condition. After preparation and tone full employment end, when machine tool rolling silk two roll the center of buy of position of wheel when the space is the largest, get on axis of core of bearing be goinged to by installation of treatment spare parts. Right now the machine tool already entered automatic loop to machine a process, feed of mobile gyro wheel, promote work and axis of core of along with bearing and bracket are placed to fixed gyro wheel at the same time, should boil press plastics of old way of whorl, turning whorl, stabilized voltage to achieve beforehand after the handling time of setting, former position of go back of mobile gyro wheel and cease. Right now, operation personnel can get off workpiece, examination whorl is departmental one-tenth size and spare parts quality are normal, according to the quality problem of existence and blemish, can analyse search an account, continue to adjust a machine tool, exclude all sorts of unusual factors, proceed boils press treatment. After it is eligible, stable, normal to wait for spare parts diameter, treatment operation can undertake automatically circularly. CNC Milling CNC Machining
