Description
The (1) technical field: the utility model relates to the machining mould, and especially a kind of compressor motor stator notch recovers mould.
The (2) prior art: the continuous upgrading along with national energy consumption market access rule and energy consumption standard, all brought higher requirement to intense market competition.Therefore, each Compressors Factory adopts the high-efficient compressor motor reaching energy-conservation purpose one after another, to the requirement of motor also in continuous upgrading, inefficient, expensive motor will be progressively by novel efficient, motor replaces cheaply.In compressor electric motor manufactured and designed, the notch of existing stator designed broad usually, and loss is big, and the harmonic content in the air gap flux density increases.The stator rabbet width should be more little good more, will be little to the stray loss of motor, and efficient will be high; Therefore, under the situation that can guarantee the setting-in coil, notch is more little good more; Efficiency of motor is just high more, if the compressor high efficiency motor can be accomplished 1.3 following notches, efficient can reach 85%.But notch is too small, and wire insertion technology can't be accomplished, and at present, is limited by the influence of wire insertion technology, and domestic electric machine stator rabbet width is generally at 1.6-2.3mm, the minimum 1.4mm that also only accomplishes.Therefore the applicant has proposed a kind of new stator production technology, is earlier that the stator rabbet punching out is less, with the notch expansion, notch is recovered behind the setting-in coil then again.In order to enhance productivity and crudy, it is very necessary designing a kind of unique stator notch recovery mould.
The (3) summary of the invention: the purpose of the utility model will improve electric efficiency exactly, satisfies the production demand of sulculus mouth motor, provides a kind of compressor motor stator notch to recover mould.The concrete scheme of the utility model is: a kind of compressor motor stator notch recovers mould; Comprise patrix partly and counterdie partly form; It is characterized in that: said patrix partly includes die shank, upper bolster, the pre-compacted cover of butt joint successively; In upper bolster and pre-compacted cover, the taper thimble is installed, the conehead of taper thimble extends the outside of pre-compacted cover downwards, and the afterbody of taper thimble places upper bolster and locatees through firm bolt; Said counterdie partly has die shoe, and the annular seating of step surface in the band is installed on the die shoe, and annular expansion set is installed in the annular seating, and annular expansion set extends upward one section, and the middle part of annular expansion set is a bellmouth, cooperates expansion with the taper thimble; At least two workpiece reference columns also are housed on annular seating.
Be to guarantee stable working, realize pre-compacted work, the utility model patrix partly in, at least two stay bolts of employing are connected between upper bolster and the pre-compacted cover; And on every bolt, be set with the compression spring, the pre-compacted cover formed with upper bolster be flexible coupling.
For making annular expansion set after expansion work is accomplished, automatically reset, make things convenient for next procedure operation; The utility model is in the counterdie part; Said annular expansion set is to be formed by the bloated piece system of enclosing of some lobes, between the bottom of the bloated piece of every lobe and the annular seating radially-directed post is housed, and back-moving spring is housed on the lead.
For making things convenient for the positioning requirements of Mould Machining and workpiece, the utility model adds a positioning sleeve in the junction, top of annular expansion set and annular seating in the counterdie part.
The utility model can be fast reduces recovery with the stator rabbet after the expansion; The limit that has realized sulculus mouth motor rule breaks through; The design and the production of the width of rebate stator motor of 0.3-1.3mm are achieved; Thereby improve electric efficiency to greatest extent, energy savings, its application prospect is very wide.
The utility model design is ingenious, simple in structure, and reliable operation is easy to operate, quick, the stator rabbet after the reduction of ability high-quality is recovered and expanded.，
