Embodiment
For the effect that describes structure of the present invention in detail and reached, the existing act under following preferred embodiment and the conjunction with figs. explanation.
As shown in Figure 1 and Figure 2, be the partial cutaway diagrammatic sketch of a better embodiment provided by the present invention, as shown in the figure, the present invention consists predominantly of:
One bent axle 1, it has the cam 12 of an off-centre, and has the driven rotating disk 11 of a concentric on the axle center of bent axle 1 one ends, can rotate synchronously with bent axle 1.
One connecting rod 2, one end are articulated on the cam 12 of bent axle 1, can produce simple harmonic motion under the drive of bent axle 1.
One slide block 3, vertical being slidedly arranged on the punch press can be carried out reciprocating punching processing running under the drive of connecting rod 2, and installs the patrix 33 of a mould in slide block 3 bottoms.
One transmission shaft 5, be located at the eccentric position of bent axle 1 one ends below, transmission shaft 5 one ends are provided with a clutch brake 71 and a flywheel 72, and on the rotating shaft of a motor 7 and flywheel 72 a sheathed drivign belt 73, flywheel 72 can be turned round under the power transmission of motor 7, and utilize flywheel 72 interlock clutch brakes 71 to drive transmission shaft 5 run-in synchronisms.The active rotating disk 51 that has a concentric on the axle center of transmission shaft 5 the other ends, it can rotate synchronously with transmission shaft 5, and initiatively has a guide slot 52 on the rotating disk 51, and cunning is established a guiding block 53 in guide slot 52.
One shaft tip 6, one end are hubbed at the eccentric position on the driven rotating disk 11 of bent axle 1, can drive bent axle 1 rotation.The other end is articulated on the guiding block 53, is slidingly installed in the guide slot 52 of transmission shaft 5, when transmission shaft 5 rotates, can link the power of transmission shaft 5 running institutes transmission under the guiding and drive of guide slot 52.
In addition, slide block 3 is slidedly arranged on the mode of execution on the punch press, can be a plurality of sliding sleeves 321 are set on punch press, and be slidingly equipped with a guide rod 32 in each sliding sleeve 321, each guide rod 32 1 end combines with slide block 3, make slide block 3 can be via the guiding of a plurality of guide rods 32 on punch press vertical slip.Also can as shown in Figure 6 a plurality of guide rods 320 be set on punch press, and slidingly on each guide rod 320 establish a sliding sleeve 322, each sliding sleeve 322 1 end combines with slide block 3, make slide block 3 can be via the guiding of a plurality of sliding sleeves 322 on punch press vertical slip.
In addition, as shown in Figure 1, be provided with a guide pillar 4 between connecting rod 2 and the slide block 3 at least, make slide block 3 can accept the drive of connecting rod 2 via guide pillar 4.
Simultaneously, can also be connected by a regulating lever 9 between connecting rod 2 and the guide pillar 4, and have helical pitch worm gear 91 on the regulating lever 9, and be provided with a worm screw 92 at regulating lever 9 sides, can engagement rotate the worm gear 91 on the regulating lever 9, to adjust the height of the slide block 3 that each guide pillar 4 is connected.
And slide block 3 bottoms also have a dish 31 nearby, can engage when the downward landing of slide block 3, and can install the counterdie 34 of a mould at platform dish 31 tops.
Adopt said structure, the present invention can make transmission shaft axle center 50 be positioned at the below (as shown in Figure 3) in bent axle axle center 10, realize effect of the present invention, particularly when transmission shaft 5 (as shown in Figure 1 and Figure 2) is accepted the running of motor 7 power transmission, shaft tip 6 can center on bent axle axle center 10 rotations (as shown in Figure 3) with driven rotating disk 11 pivot ends, simultaneously, the pivot end of shaft tip 6 and guiding block 53 can be guided groove 52 guiding and drive, and on active rotating disk 51 along the sense of rotation slippage of transmission shaft 5.At this moment, if transmission shaft 5 drives the pivot end of shaft tip 6 and guiding block 53 by 0 ° of position that turns to 90 °, the pivot end of shaft tip 6 and driven rotating disk 11 can be driven 120 ° position to bent axle 1 synchronously, according to the relation of V (speed)=L (distance)/T (time) as can be known, because bent axle 1 is compared transmission shaft more than 5 and has been rotated 30 °, so the rotational velocity of bent axle 1 is faster than transmission shaft 5, has drawing velocity preferably during making slide block 3 downward landings.The pivot end that drives shaft tips 6 and guiding block 53 when transmission shaft 5 is by 90 ° of positions that turn to 180 ° when (as shown in Figure 4), shaft tip 6 can be driven to 180 ° of positions by synchronous 120 ° of positions by bent axle 1 with the pivot end of driven rotating disk 11, therefore bent axle 1 is compared transmission shaft 5 and has been rotated 30 ° less, so the rotational velocity of bent axle 1 is slower than transmission shaft 5, the drawing velocity when making the downward landing of slide block 3 reduces gradually.Thus, the line segment length that slider displacement stroke 8 is fallen in trough 81 zones of its working depth line below 82 increases, from forming a distortion sinusoidal curve (as shown in Figure 5), autorotation speed that can also conversion bent axle 1, increasing workpiece, and then promote the stamping forming quality of workpiece by the time of slide block 3 punch process.In addition, structure of the present invention is simpler than the toggle formula punch press on the market, thus manufacturing technology be easy to control, can reduce manufacture cost.
Further implementing, the guide pillar 4 at slide block 3 tops also can be set up and be at least two guide pillars 40 (as shown in Figure 6), and a joint seat 35 is set between plain connecting rod 2 and each guide pillar 40, can under the drive of plain connecting rod 2, together produce reciprocatory motion with each guide pillar 40, the active force conduction of 40 of each guide pillars is reached unanimity, realize that each guide pillar 40 drives slide block 30 synchronously with uniform active force and carries out reciprocating punching processing running.Simultaneously, when adjusting the position of slide block 30 bottom patrixes 33, can control the accurate position precision of the slide block 30 of each guide pillar 40 bottoms institute interlock by plain connecting rod 2, and then the shut die precision of patrix 33 is controlled easily.
Can be connected (as shown in Figure 6) by a regulating lever 90 equally between connecting rod 2 and the joint seat 35, and also has helical pitch worm gear 901 on the regulating lever 90, and be provided with a worm screw 902 at regulating lever 90 sides, worm gear 901 on its engageable rotation regulating lever 90 is adjusted the height that joint seat 35 reaches the slide block 30 that is connected via each guide pillar 40.
The above is preferred embodiment of the present invention only, is not to be used to limit scope of patent protection of the present invention, and all equivalences that does not break away from invention aim of the present invention and finish are modified or displacement, all should be included in the scope of patent protection of the present invention.
