In addition, as shown in Figure 2, the first driving belt 212 is sheathed on flywheel 231 and the first belt pulley 213, can rely on rotating shaft 214 to rotate the first belt pulley 213 when the first motor 211 rotates, and then rotatable the first driving belt 212 and flywheel 231, make flywheel 231 have one first rotating speed.In addition, sheathed the second belt pulley 223 of the second driving belt 222 and the 3rd belt pulley 235 that is connected with ratchet 232, when rotating, the second motor 221 can rely on rotating shaft 224 and the second belt pulley 223 to rotate the second driving belt 222, and then can drive the 3rd belt pulley 235 and ratchet 232(and power transmission shaft 233) rotate, make ratchet 232 have one second rotating speed.
Special one carry be, the utility model does not limit certain use and wants the first belt pulley 213 and the first driving belt 212 to come flywheel driven 231 to rotate, in addition, do not limit yet and to use the second belt pulley 223 and the second driving belt 222 to drive the 3rd belt pulley 235 and ratchet 232 rotations, in other enforcement aspect, also can use other kind of drive flywheel driven 231 and ratchet 232 to rotate.For example the first power source 21 can have one first gear train (figure shows), and the first gear train can be arranged between the first motor 211 and flywheel 231, and the first motor 211 can drive flywheel 231 rotations by the first gear train.In addition, the second power source 22 also can have one second gear train (figure does not show), and the second gear train can be arranged between the second motor 221 and ratchet 232, and the second motor 221 can rotate by the second gear train driving pawl 232.
In addition, please be simultaneously with reference to Fig. 2 and shown in Figure 3, wherein, Fig. 3 is the schematic side view of the utility model non-return device 23.
Please refer to shown in Fig. 2, Fig. 4 A and Fig. 4 B, it is the action schematic diagram that is respectively the utility model non-return device 23.
As mentioned above, when the first motor 211 rotates, but flywheel driven 231 rotates, make flywheel 231 have the first rotating speed of the adjustable rotating speed of adjusting, and the second motor 221 can drive the 3rd belt pulley 235 when rotating and ratchet 232 rotates, and makes ratchet 232 have the second rotating speed of variable-ratio.
As shown in Fig. 4 A, during less than the second rotational speed N 2, when namely flywheel 231 first rotational speed N 1 were less than ratchet 232 the second rotational speed N 2, ratchet 232 backed down prong 236 when the first rotational speed N 1, make not contact ratchet 232 of prong 236, and flywheel 231 will not drive ratchet 232 and power transmission shaft 233 motions.Particularly, when flywheel 231 first rotational speed N 1 when slower (for example first rotational speed N 1 of fixing of flywheel 231 is 60rpm), the prong 236 that is fixed on flywheel 231 also and then rotates slow (rotating speed is also 60rpm), therefore, rotate ratchet 232(the second rotational speed N 2 faster greater than 60rpm) hook tooth G will back down prong 236, namely the prong 236 hook tooth G of contact ratchet 232 not, do not rotate together therefore flywheel 231 can not drive ratchet 232, certainly can not drive power transmission shaft 233 motions yet.At this moment, flywheel 231 idle running and do not drive ratchet 232 and power transmission shaft 233 rotates can not be exported crank mechanism 11, and slide block 13 will not do work, and the second motor 221 underloads and run up and do not do work.In other words, the second motor 221 does not do work and for running up, and flywheel 231 can not drive crank mechanism 11, connecting rod 12 and slide block 13 motions in the time need not doing work, at this moment, and 231 energy of being responsible for storing acting next time of flywheel.
As shown in Figure 4 B, when the first rotational speed N 1 was not less than the second rotational speed N 2, when namely flywheel 231 first rotational speed N 1 were more than or equal to ratchet 232 the second rotational speed N 2, flywheel 231 can drive ratchet 232 and rotate, and then drive power transmission shaft 233, crank mechanism 11 and connecting rod 12 motions, so that slide block 13 actings.Particularly, when flywheel 231 first rotational speed N 1 are very fast (for example first rotational speed N 1 of fixing of flywheel 231 is 60rpm), the prong 236 that is fixed on flywheel 231 also and then rotates very fast (rotating speed is also 60rpm), therefore, prong 236 can be resisted against by means of elastic parts 237 the hook tooth G(dotted portion of the less ratchet 232 of the second rotational speed N 2), flywheel 231 can rely on the hook tooth G of prong 236 contact ratchets 232 and drive ratchet 232 and power transmission shaft 233 motions this moment.Wherein, flywheel 231 relies on prong 236 pushing away ratchet 232 and power transmission shaft 233 rotates, that is to say, flywheel 231 is synchronizeed with ratchet 232, and the macro-energy that makes flywheel 231 store is output to crank mechanism 11, connecting rod 12 and drives slide block 13 actings (for example carrying out punch forming or flat die thread rolling moulding etc.).
Again one carry be, non-return device 23 of the present utility model utilizes the principle of one-way clutch, not only the structure of non-return device 23 is relatively simple, and the macro-energy that flywheel 231 stores is output to crank mechanism 11 and 13 actings of band movable slider.when not needing slide block 13 acting, flywheel 231 relies on hook tooth G to back down prong 236, make flywheel 231 not drive crank mechanism 11, connecting rod 12 and slide block 13 motions, at this moment, the second motor 221 underloads and run up and do not do work, and 231 energy of being responsible for storing acting next time of flywheel, therefore, compare with the punch press that existing pure servo motor drives, the power output of servo motor of the present utility model (the second motor 221) can not need so high (progression that is motor can be less), so, the electricity charge in the time of can saving equipment cost and use, more comparable traditional fixed speed punch press (screw spiral shell for example, the cap forming machine) output improves a lot.In addition, the utility model need not use the deceleration device of prior art, and relatively, equipment cost is also relatively low.In addition, then one carry be, the utility model capable of regulating and rotating speed when making punching press or rolling and processing meets the speed of flow of metal, and can have the high speed sky and walk stroke when not punching press or roll extrusion, make mold materials be not easy to split, therefore, also can not reduce die life and increase production cost.
In sum, because of according in punching press dynamical system of the present utility model and decompressor, when the first rotating speed of the flywheel of non-return device was not less than the second rotating speed of ratchet, flywheel can drive ratchet and rotate, and then drive power transmission shaft and crank mechanism motion, to drive the slide block acting.So, not only the structure of non-return device is relatively simple, and need not use the deceleration device of prior art, therefore, can make equipment cost relatively low.In addition, compare with the punch press that existing pure servo motor drives, the power output of servo motor of the present utility model can not need so high (progression that is motor can be less), so, the electricity charge in the time of can saving equipment cost and use, the output of more comparable traditional fixed speed punch press (for example screw spiral shell, cap forming machine) improves a lot.Therefore, punching press dynamical system of the present utility model and decompressor, not only simple in structure, can reduce energy resource consumption, have more lower production cost, and can improve output.In addition, the utility model capable of regulating and rotating speed when making punching press or rolling and processing meets the speed of flow of metal, and can have the high speed sky walk stroke when not punching press or roll extrusion, make mold materials be not easy to split, therefore, can not reduce die life yet and increase production cost.
Above explanation is just illustrative for the utility model; and nonrestrictive, those of ordinary skills understand, in the situation that do not break away from the spirit and scope that claim limits; can make many modifications, variation or equivalence, but within all falling into protection domain of the present utility model.
