The technical scheme that the utility model adopted is; A kind of high speed stamping lathe slider of punch bottom-dead-center position compensating adjusting device; Comprise the variable-frequency motor that the high speed stamping lathe is installed; And the slider of punch guiding mechanism of forming by worm screw, worm gear, adjustment nut, adjustment screw rod that connects on the bent axle that drives of variable-frequency motor, connecting rod; Described variable-frequency motor is provided with the frequency collection device, and the frequency collection device connects a signal processor, and the servomotor of installing on signal processor and the guiding mechanism worm screw is connected.
The described high speed stamping lathe of the utility model slider of punch bottom-dead-center position compensating adjusting device, its characteristic also be,
Described frequency collection device is sent to signal processor with frequency variation signal; By signal processor control driven by servomotor worm screw, the slider of punch guiding mechanism that drives worm gear, adjustment nut, adjustment screw rod composition carries out the compensation of slider of punch lower dead point position.
The utility model high speed stamping lathe slider of punch bottom-dead-center position compensating adjusting device; It sends to signal processor through the frequency collection device after with the collection of variable-frequency motor frequency variation signal; Controlling servomotor drive worm screw through signal processor; Drive worm gear rotate, and drive the adjustment nut, the adjustment screw rod is done small moving; Compensation is because speed of crankshaft changes the variation of the slider of punch lower dead point position cause, and the variable quantity of bottom dead centre is controlled to minimum, guarantees the crudy of workpiece.
Description of drawings
Fig. 1 is the utility model high speed stamping lathe slider of punch bottom-dead-center position compensating adjusting device structural representation;
Fig. 2 is the utility model high speed stamping lathe slider of punch bottom-dead-center position compensating adjusting device fundamental diagram.
Among the figure, 1. variable-frequency motor, 2. bent axle, 3. connecting rod, 4. worm screw, 5. worm gear, 6. adjustment nut, 7. adjustment screw rod, 8. frequency collection device, 9. signal processor, 10. servomotor, 11. slide block guide posts, 12. slider of punch.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is elaborated.
High speed stamping lathe slider of punch bottom-dead-center position compensating adjusting device; As depicted in figs. 1 and 2; Comprise the variable-frequency motor 1 that the high speed stamping lathe is installed, and the slider of punch guiding mechanism of forming by worm screw 4, worm gear 5, adjustment nut 6,7 that connects on the bent axle 2 that drives of variable-frequency motor 1, connecting rod 3, described variable-frequency motor 1 is provided with frequency collection device 8; Frequency collection device 8 connects a signal processor 9, and the servomotor 10 of installation is connected on signal processor 9 and the guiding mechanism worm screw 4.
The frequency collection device 8 of the utility model is sent to signal processor 9 with frequency variation signal; Drive worm screw 4 by signal processor 9 control servomotors 10, the slider of punch guiding mechanism of drive worm gear 5, adjust nut 6, adjustment screw rod 7 being formed carries out the compensation of slider of punch lower dead point position.
Just right for what the patrix that is fixed on slider of punch 12 was contacted with the counterdie that is fixed on the punch press workbench; Let the position of bottom dead centre of the slider of punch 12 adjusted at inactive state and lower-speed state; During with the change of speed of crankshaft and actual high speed stamping; The position of the bottom dead centre of slider of punch reduces to minimum with the location variation of adjusting in advance; The utility model high speed stamping lathe slider of punch bottom-dead-center position compensating adjusting device, the frequency collection device 8 that is provided with through variable-frequency motor 1 is gathered the frequency signal of variable-frequency motors when high speed stamping, and the frequency signal of gathering is sent to signal processor 9; At variable quantity through the position of the bottom dead centre that obtains slider of punch 12 after signal processor 9 analyzing and processing; And then sending compensating signal to servomotor 10, control servomotor 10 drives worm screws 4, drives worm gear 5 and rotates; Drive worm gear 5 and drive adjustment nuts 6 and do small moving, and the slide block guide posts 11 that lets adjustment screw rod 7 connect is being with slider of punch 12 to make minute movement with adjustment screw rod 7.Compensation is because variable-frequency motor 1 drives the variation of slider of punch 12 lower dead point positions that bent axle 2 rotation speed change are caused, and the variable quantity of bottom dead centre is reduced to minimum,
Timing on variable-frequency motor 1 frequency, bent axle 2 rotating speeds rise, and when variable-frequency motor 1 frequency downconverts, bent axle 2 rotating speeds descend.This moment, the bottom dead centre of slider of punch 2 also can move down along with the rising of bent axle 2 rotating speeds, moved in the decline generation along with bent axle 2 rotating speeds.Therefore adopt the utility model high speed stamping lathe slider of punch bottom-dead-center position compensating adjusting device; Just can compensate because speed of crankshaft changes the variation of the slider of punch lower dead point position that causes; The variable quantity of the bottom dead centre of slider of punch 2 is reduced to minimum, guarantee the crudy of workpiece.
Above-mentioned embodiment is an instance of the utility model; Not enforcement and the interest field that is used for limiting the utility model; All equivalences of making according to the described content of the utility model patent protection scope change and modify, and all should be included in the utility model claim.
