45mm, the system repeats ± of fixed position precision 0.
15mm. Technological process: Robot issueing core awaits arenaceous core and sandbox to reach worker worker the sandbox → robot that → vision system reachs sandbox to undertake the robot informs a system output falls good core locating arenaceous core of → robot capture puts the → inside sandbox to arenaceous core returns original position, cycle issueing core ends. Fine technology rises as what quality to cast material mechanical performance asks, original general carbon steel is replaced by low-alloy steel, if lorry shakes material of pillow, bogie side frame pledges by ZG230 - 450 raise B class steel and B+ class steel in succession, coupling material raises C class steel and E class steel by general carbon steel character. Rise as a result of what material asks character, taller to fusion equipment requirement, cast steel fusion uses electric arc heat, cast-iron use electric stove, make cast steel, cast-iron fusion quality rises greatly. The use that new technology is like technology of technology of the fine inside L-F furnace, the fine outside steel fluid furnace improved steel fluid quality further, can make steel is planted the content of S (quality mark) reach pair of levels of 0. A fine of fluid of the steel that blow argon is being fed outside furnace is craft of fine of fluid of the steel outside a kind of furnace, after tapping, to contain breathe freely steel fluid of the brick feeds aluminum steel in the bag or line of Si-Ca-Ba Bao Xin undertakes deoxidization, the brick breathes freely to purify steel fluid to gas of argon of the inbreathe in steel fluid through pottery and porcelain in the meantime, because breathe freely,bricky outfit includes floor in steel, the gas that blow argon makes steel fluid churns, form small and dispersive argon bleb. Argon bleb rise causes steel fluid churn, the petty be mingled with that can make disperse in steel fluid gets collision, assemble forms low melting point big grain be mingled with is adsorptive the exterior eduction at bleb, raised the rise rate of be mingled with thereby, achieve depurative goal. Craft of the fine outside steel fluid furnace can reduce the aeriform content in steel and field trash effectively, improve the configuration of field trash, raised cast immanent quality. This technology applies extensively already in coupling to reach shake the cast steel such as pillow, bogie side frame in production. Fall arenaceous 50 time begin 20 centuries, CO2 sclerotic water glass is arenaceous as a result of craft handy, price is low with pollution degree is small, be used extensively by manufacturing industry of cast steel of our country lorry. To 60 time metaphase, water explodes, use of water bath craft in succession, solved the difficult problem of arenaceous difficulty of water glass arenaceous Qing Dynasty, CO2 sclerotic water glass is arenaceous received wider application. But cast steel mix in casting condition stimulate cold condition to fall to produce limitation of Mao Xi crackle easily, water pollution issue is increasingly outstanding also at the same time. Rise as what ask to burden of railroad high speed, 90 time evening, lorry is important cast steel begin to use dry method to fall arenaceous craft, use generally already at present. Dry method falls arenaceous use, showing the generation that reduced crackle, for lorry moving safety reduced hidden danger. Cast steel of heat treatment van shakes pillow, bogie side frame is steel of B + class, use technology of normalizing heat treatment, coupling is E class steel, use technology of tone simple heat treatment. To raise the consistency of quality of cast heat treatment, coupling already was used continuous heat treatment craft, shake pillow, bogie side frame already also was popularized use continuous heat treatment craft. Processing of the aggrandizement that throw ball shakes pillow, bogie side frame uses the puissant processing that throw ball, improved the exterior quality of cast, form in the surface of cast at the same time press stress, in order to increase the exterior strength of cast, the fatigue resistance that increases cast then can. Cast detects the safety for burden of safeguard lorry high speed, detect to cast the technology raised taller requirement. Offer pair of cast products on one hand detect, like the iron award that implemented on July 1, 2005 TB/T3105 - 2005 " railroad van cast steel shakes flaw detection of magnetic particle of pillow, bogie side frame " , carry assembled freight car 2007 [2007]310 date file asks " railroad van cast steel shakes ray of pillow, bogie side frame takes a picture examine technical condition " , " railroad van cast steel shakes condition of technology of flaw detection of ultrasonic of pillow, bogie side frame " , " railroad van cast steel shakes magnetic particle flaw detection sets fluorescence of pillow, bogie side frame " . Detect newly the technology if flaw detection of magnetic particle flaw detection, fluorescent magnetic particle, ray flaw detection, ultrasonic flaw detection and ultrasonic are measured thick be used in succession at lorry cast. In addition, the form that still raised pair of cast nearly two years tolerancepublic errand undertakes 3 coordinate detect, applied DR to cast substance - real time is become resemble detecting with CT technology. On the other hand, used generally in cast production process fast, advanced detect technology, if read spectrometer, furnace continuously before fast analyzer, mensurable metallographic analyzer. New cast detects technical use, provided safeguard to acquire reliable cast quality. Cast technical management to cast production working procedure is much, the factor that affects quality is more complex, control of manufacturing process quality is attached most importance to especially should. For this, lorry shakes manufacturing plant carried out pillow, bogie side frame to be in charge of a branch to allot by the railway ministry " shake pillow, bogie side frame casts manufacturing technology to run a point " . Its are main content includes: The government that appearance of the management of the management of the execution of the management of file of mold design and evaluation, craft test and verify, craft, craft and examination, raw material, tool and equipment, metric instrument and detector have, employee grooms, the control of process of the control of molding process, fusion, pouring, and 22 quality record, ask cast uses one calorie is made, namely every shake pillow, bogie side frame fills in a piece of quality assures card. Cast the application of new technology, it is the fundamental strength that drives lorry high speed, burden, these new technologies already formed the industry standard that produces for lorry cast at present. As the flying development of national economy, rise ceaselessly to the requirement of lorry cast, will have updated casting the technology is applied extensively. CNC Milling CNC Machining
