The specific embodiment
For the ease of those skilled in the art's understanding, below in conjunction with embodiment and accompanying drawing the utility model is further described, the content that embodiment is mentioned not is to qualification of the present utility model.
As shown in Figures 1 to 4, a kind of one-body molded essence is taken out stator mould, comprise mould bases, upper bolster 1, die shoe 2 and be arranged at the guide pillar of mould bases, be set with mobilizable guide pin bushing on the guide pillar, die shoe 2 is connected with guide pillar, upper bolster 1 is connected with guide pin bushing, upper bolster 1 is provided with punch 3, die shoe 2 is provided with die 4, described punch 3 is provided with angle cam trimming drift 5, vertical trimming punch 6 and blanking die, described die 4 is provided with respectively and angle cam trimming drift 5, first stamping-out cover 8 that vertical trimming punch 6 and blanking die adapt, second stamping-out cover and the second stamping-out cover, described punch 3 is provided with porose drift 11, stretch drift 13 under bending shaping cover 15 and at least three extension elongation β are unequal mutually, stretch under at least three drift 13 according to job order from being short to long array, reduce gradually from the described diameter of stretching drift 13 down that is short to long array; Described die 4 is equiped with hole drift 11 corresponding punching covers 14 and with the bending shaping and overlaps 15 corresponding bending drifts 12, and the internal diameter of this punching cover 14 and the diameter of hole drift 11 adapt; Described die 4 offers and down stretches the identical shrinkage pool of drift 13 quantity, is provided with stamping-out cover 16 in each shrinkage pool, and stamping-out cover 16 is with to stretch drift 13 down corresponding one by one, and stamping-out overlaps 16 internal diameter and the following diameter of stretching drift 13 and adapts.
In process, punch 3 is done motion up and down under the effect of driving mechanism, when punch 3 is moved downward near die 4, described angle cam trimming drift 5, vertical trimming punch 6, hole drift 11, bending drift 12 and blanking die are inserted into corresponding first stamping-out cover, 8, the second stamping-out cover, punching cover 14 respectively, bend in shaping cover 15 and second stamping-out cover, at least three unequal mutually drifts 13 of stretching down of length are inserted into respectively in the stamping-out cover 16 that adapts, to realize stamping-out or punching press action.Strip 23 is at from left to right intermittence in the moving process, a machining position of strip 23 station that whenever moves right, and punch 3 moves once up and down.
Cut edge by the left and right sides of 5 pairs of these machining position of angle cam trimming drift earlier, cut edge by the both sides up and down of 6 pairs of these machining position of vertical trimming punch, after twice side cut, this machining position leaves crooked scrap (bridge); Successively strip 23 is carried out punching press by stretching drift 13 under at least three according to job order more subsequently, strip 23 is stretched under first after drift 13 punching presses, this machining position little blind hole of the big degree of depth of diameter that is stamped out; Subsequently, strip 23 station that moves right carries out punching press by stretching 13 pairs of these machining position of drift under second, makes the degree of depth of described blind hole become big, and diameter diminishes; Through stretching under at least three after the punching press successively of drift 13, the degree of depth of blind hole and diameter all reach the setting requirement, thereby obtain the one-level blank of motor stator, i.e. the first half blank; Subsequently, carry out the punching processing by the bottom of hole drift 11 and 14 pairs of the first half blanks of punching cover, thereby obtain the secondary blank of motor stator, i.e. the first half; Secondary blank by bending drift 12 and 15 pairs of motor stators of bending shaping cover carries out the bending shaping processing of the latter half again, obtain three grades of blanks of motor stator, by blanking die resulting three grades of blanks stamping-out from the strip 23 is got off at last, promptly obtain final motor stator finished product.Because through after twice side cut, machining position leaves crooked scrap (bridge), scrap (bridge) crooked in the process can not broken away from machining position with strip 23 by stretching gradually, guarantees machining position before blanking, and machining position moves right with strip 23 all the time.Utilize and stretch 13 pairs of strips of drift 23 under a plurality of and carry out repeatedly punching press, gradually it is struck out standard compliant dimensions, guarantee that the diameter and the overall height in inside and outside hole meets the requirements of accuracy, the rate of reducing the number of rejects and seconds greatly, machining accuracy improves greatly.
One-body molded essence described in the utility model is smoked the motor stator mould and is integrated precision and smoke dark and bending stamping-out, can carry out precision to motor stator and take out dark and bending stamping-out, the first half of motor stator and the welding between the latter half have been avoided, simplified the manufacturing procedure of motor stator greatly, difficulty of processing is lower, the production efficiency height.
Stretch under described adjacent two of present embodiment and be provided with worker's drift 17 of standing between the drift 13, worker's drift 17 of standing is connected with described punch 3; Described die 4 offers the calibration shrinkage pool that drift 17 quantity equate of standing with the worker, is provided with calibration cover 18 in the calibration shrinkage pool, and calibration cover 18 and the worker drift 17 of standing is corresponding one by one, calibrates to overlap the stand diameter of drift 17 of 18 internal diameter and worker and adapt.Utilize worker's 17 pairs of strips 23 of drift of standing to calibrate the location, guarantee the concentricity of the pipe thickness uniformity and inside and outside wall.
Be set with locating pin 19 in described each stamping-out cover 16 of present embodiment, submergence depth α and the corresponding extension elongation β that down stretch drift 13 of the upper end of this locating pin 19 in stamping-out cover 16 adapts.Locating pin 19 is used for the following pan position of stretching drift 13 is down positioned, the excessive and damage equipment of the moving displacement that prevents from down to stretch drift 13 or damage processed workpiece, and practicality is stronger.
The lower end of the described locating pin 19 of present embodiment is provided with strengthening cap 20, and strengthening cap 20 is embedded in the die shoe 2, is used to improve the bonding strength of locating pin 19 and die shoe 2, increases the service life.
The below of the described punch 3 of present embodiment is provided with correcting plate 21, offers several correcting holes on this correcting plate 21, stretches drift 13 under each and passes a correcting hole.Concrete, described angle cam trimming drift 5, vertically stretch drift 13, hole drift 11, bending drift 12 and blanking die under the trimming punch 6, at least three and be set in turn in described punch 3 according to manufacturing procedure.Being provided for of correcting hole carried out more accurate correction to the pressing direction of stretching drift 13 down, prevents from down to stretch drift 13 and lateral shifts takes place and influence the wall thickness uniformity of metal tube and the concentricity of inside and outside wall, and machining accuracy is higher, and practicality is stronger.
The described hole drift 11 of present embodiment and bending are provided with between the drift 12 cuts shape drift 22, and this is cut shape drift 22 and is connected with described punch 3, and described die 4 is provided with and cuts the shape of cutting that shape drift 22 adapts and overlaps.Cut shape drift 22 and cut the shape cover and cut shape processing before being used for the secondary blank that is about to bend shaping bent, make the contour structure size precision more of the latter half of motor stator, further improve machining accuracy.
The foregoing description is one of preferable implementation of the utility model; in addition; the utility model can also realize by alternate manner that any conspicuous replacement is all within protection domain of the present utility model under the prerequisite that does not break away from the present utility model design.
