Description
Technical field
The utility model relates to the slice stamping field, particularly relates to a kind of self-discharging motor stator monolithic punching mechanism.
Background technology
Motor is a kind of equipment of mechanical energy that electric energy is converted to, it is to utilize stator winding to produce rotating magnetic field and act on the closed aluminium frame of rotor mouse cage to form magnetoelectricity dynamic rotation moment of torsion, under the effect of stator winding rotating magnetic field, in the closed aluminium frame of mouse cage, have electric current by and be subject to the effect in magnetic field that the aluminium frame is rotated.Stator core generally by 0.35-0.5 millimeters thick surface have insulating barrier punching silicon-steel, be overrided to form, the circumference upper punch of silicon steel sheet has equally distributed groove, in order to embed stator winding, the centre punch of silicon steel sheet has circular hole, for the installation of stator.
Self-discharging motor stator monolithic punching mechanism is that monolithic to be rushed is placed on lower cavity die, and upper male mould undershoot under the active force of die shank completes the punching in required hole and groove on silicon steel sheet.Yet monolithic tends to stick on upper bolster in punching course, after stickup, need manually monolithic just can be carried out to punching press next time after upper bolster separates, affect ram efficiency.
The utility model content
For monolithic in the punching course of above-mentioned existence, tend to stick on upper bolster, after stickup, need manually monolithic just can be carried out to punching press next time after upper bolster separates, affect the problem of ram efficiency, the utility model provides a kind of self-discharging motor stator monolithic punching mechanism.
For addressing the above problem, the self-discharging motor stator monolithic punching mechanism that the utility model provides solves problem by following technical essential: self-discharging motor stator monolithic punching mechanism, comprise die shoe, be arranged on the die of described die shoe upper surface, upper bolster directly over described die shoe, be positioned at the punch that described upper bolster below and upper bolster are set to one, the below of described upper bolster also is provided with discharging rubber and the de-liner plate that all there is through hole at center, described discharging rubber is between upper bolster and de-liner plate, and with the lower surface of upper bolster and the upper surface of de-liner plate, contact respectively, described punch is positioned at the through hole of the center setting of discharging rubber and de-liner plate.
Pass through this set, the monolithic that punching press completes in punching course sticks on the lower surface of de-liner plate, after completing punching press, upper bolster moves upward, the resilience in upper bolster moves upward process of the compressive deformation of discharging rubber when upper bolster presses down, after de-liner plate is defined with respect to the position of upper bolster, monolithic also has the speed of discharging rubber resilience, makes monolithic separate with de-liner plate.
Preferably, also comprise die shank, described die shank is fixed on the middle position of upper bolster upper surface.
The die shank arranged is intended to be beneficial to being connected of upper bolster and slider of punch, makes slider of punch drive upper bolster move along the direction of motion of slide block.
Preferably, on described de-liner plate, also be provided with the reducing bolt hole, in the reducing bolt hole, be provided with screw, the end of thread of described screw is connected with upper bolster.
The reducing bolt hole arranged and screw are intended to limit the extreme lower position of de-liner plate with respect to upper bolster, adopt screw to connect simultaneously, convenient de-liner plate dismounting, i.e. and when discharging rubber generation plastic deformation or elasticity are not enough, the replacing of aspect discharging rubber.
Preferably, described die shoe upper surface also is provided with guide pillar, also is provided with the guide pillar hole on the upper bolster directly over described guide pillar, and the guide pillar internal surface of hole also is provided with guide pin bushing, and described guide pin bushing internal diameter is than the large 0.1-0.2 millimeter of guide pillar external diameter.
Be separately positioned on guide pillar on die shoe and the guide pillar hole on upper bolster, the restriction upper bolster can only move along the guide pillar direction with respect to die shoe, guide pillar and the guide pillar hole of a plurality of pairings are set, can further limit the movement locus of upper bolster with respect to die shoe, thereby guarantee to be fixed on punch on upper bolster with respect to the position relationship that is arranged on the die shoe upper cavity die, improve the positioning precision of punch and die; The guide pin bushing arranged is intended to avoid the guide pillar hole directly to contact with guide pillar, necessary integral replacing upper bolster, die shoe or processing guide pillar after wearing and tearing, after adopting material to be softer than the guide pin bushing of guide pillar material, wearing and tearing generally only occur, on guide pin bushing, when quality of fit does not meet the demands, only need change guide pin bushing; Employing has the guide pin bushing of self lubricity, is conducive to reduce the wearing and tearing of guide pin bushing and guide pillar; The guide pin bushing internal diameter arranged, than the large 0.1-0.2 millimeter of guide pillar external diameter, when considering guide pin bushing and guide pillar working ability, is considered guide pin bushing and guide pillar thermal coefficient of expansion and the guide pin bushing of requirement and the quality of fit of guide pillar in the course of the work.
Further, the material of institute's guide pin bushing is copper, and the material of described guide pillar is carbon steel.
Be arranged to the guide pin bushing material and be softer than the guide pillar material, make described guide pin bushing and guide pillar wear and tear at work and mainly occur on guide pin bushing, only need to change guide pin bushing after guide pin bushing and the decline of guide pillar quality of fit, be conducive to protect guide pillar.
Preferably, also be provided with on the junction axial direction of described die shoe and guide pillar and there is flexible lining.
Adopt as lining that material is rubber, be conducive to press down stroke when larger when upper bolster, avoid the guide pin bushing on upper bolster to contact with the direct rigidity of die shoe, protect upper bolster parts and die shoe not damaged.
The utlity model has following beneficial effect:
The monolithic that punching press completes in punching course sticks on the lower surface of de-liner plate, after completing punching press, upper bolster moves upward, the resilience in upper bolster moves upward process of the compressive deformation of discharging rubber when upper bolster presses down, after de-liner plate is defined with respect to the position of upper bolster, monolithic also has the speed of discharging rubber resilience, makes monolithic separate with de-liner plate.
