In the corner location of installation pedestal, telescopic end is against on material pressing core 51, when for the switching of switching mechanism working condition, is provided vertical
The switching power just moved upwards.The stroke for switching nitrogen gas spring 35 is greater than the stroke of binder nitrogen gas spring 34.
Pedestal flipper guide 36: being fixedly mounted on 315 border side wall of insert mounting base, and edge-on in border material pressing core 41
Wall slide guide, slide guide is oriented to when playing border material pressing core 41 and the movement of installation pedestal 31.
Flanging and restriking insert 37: flanging and restriking cavity plate, when work and flanging forming is completed in the cooperation of the punch-pin of lower die.
Border material pressing core 41: the substantially ring structure similar with day window shape is mounted on by binder work bolt 33
In installation pedestal 31, it to be used for skylight border binder.
Internal pressure core flipper guide 42: it is fixedly mounted on the outside border wall of border material pressing core 41, contacts and leads with material pressing core 51
It is sliding, play the role of slide guide guiding.
Material pressing core 51: it is used for top cover outside plate entirety binder, is connect with upper die holder.
In actual use, when production has the top cover of skylight, switching mechanism working condition is as shown in Figure 1, Figure 2, Figure 4 shows, gas
Cylinder 16 is ejection state, and switching bracket 11 moves to front side, switches the lower surface of bracket 11 and the nitrogen gas spring of installation pedestal 31
The bracket slide guide face 312 of 311 bottom of mounting base contacts.When punching production upper die holder declines, material pressing core 51 first contacts product progress
Binder, upper die holder continue downwards, border material pressing core 41 start contact skylight border plate, subsequent binder nitrogen gas spring 34 gradually by
Pressure-plate-force is compressed and provides, then upper die holder continues to move downward, and the flanging and restriking insert 37 in installation pedestal 31 carries out skylight
Flanging and restriking work.After material pressing core 51 starts binder, switching nitrogen gas spring 35 is gradually compressed up to mold closure.
When producing the top cover without skylight version, working condition switches to off working state, referring to Fig. 9 Figure 10, detailed process
As follows: cylinder 16 shrinks and drives the 11 mobile set distance in whole side backward of switching bracket, and switching nitrogen gas spring 35 will always
In uncompressed free state, installation pedestal integrated support is located inside material pressing core 51, the frame body of switching bracket 11 exists
Projection in installation pedestal 31 is located in the groove that nitrogen gas spring mounting base 311 is formed.When punching production, upper mold is moved downward,
Material pressing core 51 first contacts product and carries out binder, then carries out corresponding press work content, until mold is closed.In the process
Switch nitrogen gas spring 35 and be in jack-up state always, so that border material pressing core and installation pedestal are integrally located on 51 type face of material pressing core
Side, flanging and restriking insert 37 is not involved in work, while binder nitrogen gas spring 34 is free elongation state, and protects with border material pressing core
There are 2mm distances.Until the chassis body for switching bracket 11 can be in nitrogen gas spring installation in installation pedestal 31 when mold closure
In the groove that seat 311 is formed, reach state as shown in Figure 9, Figure 10.
In addition, pedestal flipper guide 36 and internal pressure core flipper guide can rise during punching production and the above two state of switching
The effect being oriented to slide guide, while installation pedestal 31, border material pressing core 41, material pressing core 51 are effectively ensured relatively stable
State.
Structure, feature and effect of the invention, the above institute are described in detail based on the embodiments shown in the drawings
Only presently preferred embodiments of the present invention is stated, but the present invention does not limit the scope of implementation as shown in the drawings, it is all according to structure of the invention
Think made change or equivalent example modified to equivalent change, when not going beyond the spirit of the description and the drawings,
It should all be within the scope of the present invention.
