The both ends of support spring 15 are connected to gag lever post 10 and stopper respectively, and when extracting gag lever post 10 out, support spring 15 is compressed, when
Handle 32 is unclamped, until the one end of gag lever post 10 is alignd again with spliced eye 9, gag lever post 10 is embedding under the active force of support spring 15
Enter in spliced eye 9, improve the fixed efficiency of mould.
As shown in Figure 2 and Figure 6, fillet surface 91 is set in the inserted terminal of spliced eye 9, when gag lever post 10 enters spliced eye 9,
One end of gag lever post 10 abuts with fillet surface 91, and fillet surface 91 guides gag lever post 10 to enter spliced eye 9, reduces the deflection of gag lever post 10
Abutting cannot be introduced into spliced eye 9, improve the splicing stability of gag lever post 10.
Specific implementation process：
The punching position adjustment of punch-pin 12 and die hole 22：Handle 32 is twitched, when support spring 15 can not be compressed, illustrates limit
Position bar 10 completely disengages spliced eye 9, is then plugged in by die nut in the inserting groove 811 in rotary shaft 81, and drives and turn
Moving axis 81 so that the rotation for the gear 8 being connected with rotary shaft 81, rack 7 are fixed, so that length side of the gear 8 along rack 7
To rolling, under the restriction of slideway 5, gear 8 drives top shoe 3 to be moved with sliding block 4 along slideway 5, now spliced eye 9 and gag lever post
10 dislocation, unclamp handle 32, and gag lever post 10 is connected to top shoe 3 or sliding block 4, until spliced eye 9 is right with gag lever post 10 again
Together, gag lever post 10 is embedded in spliced eye 9 again under the deformation force effect of support spring 15, is realized to top shoe 3 and sliding block 4
Fixation.
Blanking process：Mold 1 is pushed, and stripper 19 abuts with concave template 21, and upper bolster 13 is held with punch retainer 11
Continuous to glide, the punch-pin 12 of the setting on punch retainer 11 cooperatively forms punching through stripper 19 with die hole 22；Work as punching
After the completion of, upper bolster 13 slides straight up with punch retainer 11, due to the square between punch retainer 11 and stripper 19
Shape spring 201 is compressed in punching, and stripper 19 keeps abutting with the sheet material on concave template 21, until punch-pin 12 is completely de-
From die hole 22.
Embodiment two is compared to be with the difference of embodiment one：
As shown in Figure 7 and Figure 8, the drive component for setting driving gag lever post 10 to move on punch retainer 11, drive component bag
