The specific embodiment
See also Fig. 1 and in conjunction with Fig. 2 and Fig. 3, the die set shown in the figure comprises male model member and master mold member.Described male model member comprises counterdie 1, counterdie slide 2, following moulded board 19, cylindrical guide 6, cylindrical guide seat 7, interior angle thin nut 24, clamp nut 10, hexagon-headed bolt 28.See also Fig. 2, cylindrical guide seat 7 has two, is installed in cylindrical guide 6 both sides respectively, and a side is fixed by the socket cap of cylindrical guide 6, and the inner angle of side thin nut 24 is fixing.Between counterdie slide 2 and the cylindrical guide 6 steel bushing 16 is installed.Two cylindrical guide seats 7 define the motion path of counterdie slide 2.Hexagon-headed bolt 28 is fixed on counterdie 1 on the counterdie slide 2 by clamp nut 10, and like this, when 2 motions of counterdie slide, counterdie slide 2 just can drive counterdie 1 and move towards the stamping position of workpiece.Counterdie 1 matches with the profile of workpiece, and is provided with towards pin (not shown) in stamping position.
The master mold member comprises drift 8, punch holder 9, positioning seat 17, soket head cap screw 22, and wherein soket head cap screw 22 is fixed drift 8, punch holder 9 and positioning seat 17 threes.The center of positioning seat 17 is exactly the centre of location A of workpiece.See also Fig. 2, when carrying out punching press, workpiece is placed on the drift 8, promptly on the location of workpiece B.See also Fig. 3, the master mold member also comprises the buffer unit that is installed on above the positioning seat 17, and it comprises guide rail 5, guide rail pad 11, needle roller 34, cages for needle 12, roller guide retainer 4.Guide rail 5 is connected (consulting Fig. 3) with guide rail pad 11 by soket head cap screw 33; Guide rail pad 11 is connected (consulting Fig. 1) with cages for needle 12 by taper bolt 21; Connect by straight pin 13 between roller guide retainer 4 and the guide rail 5, and straight pin 13 is equipped with adjustment magnet 13 away from roller guide retainer 4 one sides.Because the master mold member is provided with buffer unit, the master mold member can carry out displacement more by a small margin when forces are applied like this, and such structure can effectively be avoided the distortion of workpiece in punching course, easily the controlling dimension precision.
In addition, be respectively equipped with fixture on the male model member of die set shown in Figure 1 and the master mold member.The male model member can respectively be established a fixture at counterdie 1 towards about pin, the master mold member can be provided with the set positions of corresponding counterdie 1 upper fixing element on drift 8 or punch holder 9.Need to prove that these fixtures (not shown) are scalable installations, that is to say that these fixtures only just can be fixed the left and right sides and the interior outside of workpiece stamping position and fix in punching press.After finishing a station, described fixture withdrawal, next station of arrival so that workpiece rotates, rises, descends.
Described die set is provided with the parts (fixture) of fixation workpiece on the male and female die component, make workpiece be not easy to deform in punching course.In addition, the master mold member is provided with buffer gear, can realize the impact style that floats like this, even the out-of-shape of workpiece also can be controlled at the dimensional accuracy of workpiece in the claimed range.
Adopt the numerical control stamping machine tool of process for stamping of the present invention to comprise that above-mentioned die set, fluid pressure drive device, feed mechanism (are lifting platform, as shown in Figure 1).This lifting platform comprises base 38, lifting shaft 37, plummer 36, workbench 35.Lifting platform is placed on workpiece to be punched on the workbench 35 by handler when initial position, and perhaps that punching press is good workpiece is unloaded down from workbench 35.After the described lifting platform starting, lifting shaft 37 can be done rising, descending motion under the driving of hydraulic pump.
Fig. 4 is the block flow diagram of the process for stamping of the embodiment of the invention, understands this process for stamping for clearer, below the step of this process for stamping is described one by one:
(1) power on, pilot engine, engine drives fluid power system pressure and starts automatically; This fluid power system comprises first fluid power system on the die set and second fluid power system that is positioned at lifting platform; First fluid power system comprises oil cylinder 18, piston rod 20 and the piston that is connected with piston rod 20, sees also Fig. 1;
(2) workpiece to be punched is installed on the workbench 35 of lifting platform, has locating shaft (not shown) on the workbench 35, workpiece is positioned fixing, rotate this locating shaft by servomotor, can realize workpiece is rotated, so just can change the stamping position of workpiece, with diverse location upper punch waist hole at workpiece;
(3) initial setting, cycle-index I=0 need be N in the number in workpiece upper punch waist hole;
(4) workpiece is installed after, lifting platform rises, promptly lifting shaft 37 extends upward under the effect of second fluid power system (also can adopt other adaptable drive systems), drives workbench 35 and moves up to the precalculated position;
(5) lifting platform release;
(6) servomotor carries out the corner location by locating shaft to workpiece;
(7) lifting platform continues to rise to first station, and at this moment, the fixture that is positioned on male model member and the master mold member extends respectively, thereby with about fixing around the stamping position of first station of workpiece, workpiece can not be offset when being subjected to big impulse force; Wherein, adjust the height of current workpiece by adjusting distance that work stage rises, on the differing heights of current workpiece, to form the waist hole;
(8) then, punching cylinder stretches out; Be that the first hydraulic drive system drives counterdie 1 shown in Figure 1 moves right and carries out punching press; Because in punching course, the fixture on counterdie 1 and drift 8 or the punch holder 9 towards adopting method of clamping to fix near the stamping position in waist hole, has avoided stamping press to cause the workpiece skew workpiece; In the present embodiment, described fixture is fixed on adjacent two stamping position places of the current stamping position of current workpiece; In addition, institute's use master mold member is provided with buffer gear, has realized unsteady impact style, has avoided like this causing the undesirable phenomenon of dimensional accuracy because of the out-of-shape of workpiece;
After (9) stations were finished, punching cylinder was return, and promptly counterdie 1 returns to initial position under the drive of first fluid power system;
(10) judging whether punching press number of times I equals need need be towards the number N in waist hole at current workpiece, if I＜N, I=I+1, the execution in step that circulates (2)～(9); Otherwise, execution in step (11);
(11) lifting platform descends, and changes workpiece, and (2)～(10) are carried out in circulation, realizes producing in batches.
Foregoing description; only being the specific descriptions to preferred embodiment of the present invention, is not to any qualification of the present invention, for the person of ordinary skill of the art; can carry out simple modification, interpolation, conversion according to above-mentioned disclosure, and all belong to the content of protecting in claims.
