Face contacts with each other with the upper surface of punching and blanking multistation die 21, and then, loading and unloading material plate 4 contacts with die limit for height block 20 and presses
Contracting loading and unloading material spring is until the spacing dead-centre position of loading and unloading material plate caging bolt 13;
The most then, rush step pitch hole punch 6 and contact with locking packing ring blank 26 and continue to move downward, until working on lathe
Till platform runs to bottom dead centre, make locking packing ring blank 26 rush step pitch hole punch 6 and punching and blanking multistation die 21 it
Between effect under complete two punching determining step pitch circular hole, punch process i.e. for the first time;Current process process status such as Fig. 3
Middle OP1O(the first station) shown in.
3rd step, work platforms and upper mold upwards return on forcing press, meanwhile, autoloader is by roll-shaped banding
Locking packing ring blank 26 has gone up from two rows between the retainer pin 25 of return and forwards feeds, it may be assumed that advance into from left to right
The top of the next station of this station, the waste material after punching falls to fall into from lathe material spilling hole and is placed on giving up below lathe
In hopper;
4th step, repeats second step 1. process, starts forcing press and locking packing ring blank 26 carries out second time punch process,
In the process, the step pitch hole pilot pin 15 of two pieces punching 12 assembling small sircle hole enters locking packing ring blank 26 for the first time
Positioning further in the step pitch circular hole that punching is good, punching is installed Pinhole Punch 9 and is synchronized contact and continue with locking packing ring blank 26
Continue and move downward, until work platforms runs to bottom dead centre on lathe, make locking packing ring blank 26 rush step pitch hole punch
6, punching complete under the effect between Pinhole Punch 9 and punching and blanking multistation die 21 is installed two second time determine step pitch circular hole and
The punching of 12 assembling small sircle holes;Current process process status such as OP2O(the second station in Fig. 3) shown in.
5th step, repeats the 3rd step;
6th step, repeats second step 1. process, starts forcing press and locking packing ring blank 26 carries out third time punch process,
In the process, four step pitch hole pilot pins 15 of punching 12 assembling small sircle hole and punching installation macropore punch enter locking pad
Position further in the step pitch circular hole that circle blank 26 is for the first time, punching for the second time is good, rush step pitch hole punch 6, punching installation
Pinhole Punch 9 is installed macropore punch 10 and is synchronized contact and continue to move downward with locking packing ring blank 26 with punching, until on lathe
Till work platforms runs to bottom dead centre, wherein, punching is installed dislocation on macropore punch 10 and is provided with punching installation Pinhole Punch 9, makes lock
Only packing ring blank 26 is rushing step pitch hole punch 6, punching installation Pinhole Punch 9, punching installation macropore punch 10 and punching and blanking multistation
Complete two third times under effect between die 21 and determine step pitch circular hole, 24 assembling small sircle holes and an assembling big hole
Punching;Current process process status such as OP3O(the 3rd station in Fig. 3) shown in.
7th step, repeats the 3rd step;
8th step, repeats second step 1. process, starts forcing press and locking packing ring blank 26 carries out the 4th punch process,
In the process, six step pitch holes of punching 12 assembling small sircle hole, punching installation macropore punch and punching installation macropore punch are led
Positive pin 15 enter locking packing ring blank 26 for the first time, for the second time, carry out in the good step pitch circular hole of punching for the third time fixed further
Position, subsequently rushes step pitch hole punch 6, punching installation Pinhole Punch 9, punching installation macropore punch 10 and blanking punch 11 and locking packing ring
Blank 26 synchronizes contact and continues to move downward, until work platforms runs to bottom dead centre on lathe, makes locking washer blank
Material 26 is rushing step pitch hole punch 6, punching installation Pinhole Punch 9, punching installation macropore punch 10, blanking punch 11 and punching and blanking multiplexing
Complete two second circulations under effect between the die 21 of position and determine step pitch circular hole, 24 assembling small sircle holes and one for the first time
The punching of assembling big hole and the blanking of a locking packing ring 19;And reach blanking external diameter φ 88.5 mm, macropore internal diameter φ is installed
52.2 mm, seam width 8.0 mm, seam position are by width 49.5 mm, installation hole diameter φ 7.0 mm, installation aperture
Position φ 76.0 mm, installation aperture are relative to position degree 0.16 mm of product design;After punching and blanking, the knot of workpiece
Structure as shown in Figure 4, Figure 5, current process process status such as OP4O(the 4th station in Fig. 3) shown in.
9th step, repeats the 3rd step;
Tenth step, repeats second step 1. process, starts forcing press and locking packing ring blank 26 carries out the second circulation for the first time
Punch process, in the process, punching 12 assembling small sircle hole, punching are installed macropore punch and rush six of installation macropore punch
Step pitch hole pilot pin 15 enter locking packing ring blank 26 second time, for the third time, step pitch circle that the second circulation for the first time punching is good
Position further in hole, rush step pitch hole punch 6, punching installation Pinhole Punch 9, punching installation macropore punch 10, blanking punch 11
Cut off upper mold 12 to synchronize contact and continue to move downward with locking packing ring blank 26 with leftover pieces, until work platforms fortune on lathe
Row, to bottom dead centre, makes locking packing ring blank 26 rush step pitch hole punch 6, punching installation Pinhole Punch 9, punching installation macropore punch
10, two fixed steps of two second circulation second time are completed under the effect between blanking punch 11 and punching and blanking multistation die 21
Away from circular hole, 24 assembling small sircle holes and the punching of an assembling big hole and the blanking of a locking packing ring 19, and simultaneously
Locking packing ring blank 26 and locking packing ring is completed under the effect that leftover pieces cut off between upper mold 12 and leftover pieces cut-out lower mold 17
The separation of leftover pieces 16;Current process process status such as OP5O(the 5th station in Fig. 3) shown in.
Carry out Continuous maching by the above process.
Use the locking packing ring profile that automobile drive axle locking packing ring punching and blanking progressive die of the present utility model makes
Dimensionally stable passes through in blanking external diameter φ 88.5 mm, installation macropore internal diameter φ 52.2 mm, seam width 8.0 mm, seam position
Width 49.5 mm, installation hole diameter φ 7.0 mm, installation aperture position φ 76.0 mm, installation aperture are relative to product design
Position degree 0.16 mm, the concordance of product monnolithic case is regular, and the sustainable stable overall dimensions guaranteeing locking packing ring reaches
Design requirement to product drawing.Also production capacity is improved, this light truck-type drive axle locking pad while improving product quality
Blank feed, product blanking and the leftover pieces discharging process of circle are the most smooth and easy, stable, and the maintenance time of punching and blanking progressive die
Number to significantly reduce than the mold repair number of times of traditional handicraft, and die life is significantly improved.Single products split run production capacity by
3800 are promoted to 8600, and split run production capacity improves 126.3%.
