Hydraulic pressure of H160/25 programmed control coils earphone is transformed

05 document label piles up: Hydraulic pressure of H160/25 of B my company programmed control coils earphone, basically finish all sorts of cars a smooth ear of board reed, center ear and Bao Er, it is the crucial equipment that board reed machines. It can circle heating board base core axis to coil make shape. Pass old maintenance and specific aim to transform, obtained better economic benefits. One, problem analysis and solve 1. The pattern is mixed, change adjust difficulty, market of not downy equipment cuts manufacturing efficiency head, dozen curved, shape at a suit, although the structure is compact but operation space is relatively narrow, change every time those who cut a head want to change at the same time when breed " V " model piece, cut axis of knife, core and core axis rotary sleeve to wait, time-consuming it is long, difficult to adjust. When transforming, will cut with roll ear process is separate, make cut dozen of turn and roll ear undertakes at the same time, shortened the handling time of every leaf spring, efficiency rises greatly. When breed is adjusted, cut working procedure is mixed the mould of an ear working procedure can change at the same time, the time that change a pattern decreases greatly. Structure of former core axis includes outside fixed cylinder, inside oriented copper is covered, core axis is fixed set, core axis crock, when transforming will outside semicircle of fixed cylinder make it opens wide type, join with a hinge of core axis crock at semicircle canister rear, replace oriented copper to cover with oriented lever make a structure more compact and intuitionistic, change a pattern more convenient and quick. 2. Roll ear connect is seamed not stable, when the angle that include side is more than 240 ° cannot shape original turning mechanism is crock of hydraulic pressure of rack drive piston drives crankshaft to rotate, corner coming back is spent through adjusting journey switch and flange dish the position of armature comes true. Because do not have contact switch, PLC to output relay and electromagnetism reversal valve 3 person answer precision error and random failure, cause an error of side point of view to slant great quality is not stable. Because rotate formerly crock rack journey is small reach workbench structure limitation to wait, the ability after the mould when old point of view includes side must make a turn first shapes, cost is efficient low. Italy is chosen to produce coder of DKZOR-A-171-L5 scale reversal valve, PIE-1800-G24C photoelectricity when transforming, dial a code dish etc form angle to detect orgnaization, differ according to the product dialing a code directly dish on the corner coming back that the setting needs is spent, intuitionistic and convenient, PLC new process designing, implementation ends new to clear circularly every time, rotate circularly every time angle error is less than 1 ° . New treatment rotates crock end lid reachs journey adjustment link stopper, increase the journey of rack, with cast steel replace cast-iron a bedplate of the new job that make, in ensure to workbench bulk and thickness are reduced as far as possible below the condition of intensity. The corner coming back after transforming spends 0~270 ° successive and adjustable, ensure old point of view wraps ear to be able to shape. 3. Roll earhole diameter volume is not steady, the mould wears away fast, life weak point coils the path after earhole diameter is affected directly controls a process, bore diameter slants big earhole lining and earhole cooperate clearance to cross Dayisong to take off, bore diameter slants small press fashionable and changeful form to affect exterior quality. The element that causes earhole size to be not stabilized heats besides preform outside temperature, basically be a be heated of ear core axis expand cause earhole aperture to heat up deflection different be caused by, anneal of long-term be heated accelerates core axis again its wear away. In transforming, divide cold outside circular cooling water is used when core axis go back, still be on the foundation that assures an intensity of ear core axis machine in center of each core axis enough long inside aperture, introduce with copper pipe inside circular water cold. The effect is used after transforming good, heat in preform below the case with particular temperature, bore diameter deviation is in person 0.

Lmm less than, accord with craft requirement completely. 4. Workbench height adjusts inconvenience, oil of leakage of hydraulic pressure crock overhauls frequent former workbench badly the adjustment of perpendicular direction relies on ratchet orgnaization to come true, because ratchet teeth of a cogwheel is smeary reach use time to grow easy wear away skid, length of together with workbench is longer, rise the around when falling hard synchronous, often get stuck dead. The around when transforming uses worm of double worm wheel intermediate join with a hinge, the simply when adjusting adjusts the adjustment of worm of back end worm wheel handle can realize workbench around synchronism to rise fall, convenient save labour. Cut worker worker press a crock beforehand, cut crock and roll ear is versed in because clamp crock, impaction crock is long-term be heated, sealing ring is easy thermoplastic ageing loses sealed action and leakage is oily, u is chosen when transforming model get together ammoniac fat replaces former Yx group into gasket, machine cooling conduit to introduce cooling water inside the osculatory face plate that presses crock and impaction crock beforehand. 2, it is normal that the equipment after transforming the effect moves, fault rate is reduced greatly, manufacturing efficiency and product quality have bigger rise, economic benefits is remarkable.
