Lead is delivered to lead guider 35 by power, and then lead is fixed on punching inserting mechanism 4 by lead guider 35
In the groove 75 of block 71, and then lead is delivered in gun barrel 6, after the completion of traction, cylinder drives the second spur gear 31 fortune upwards
Dynamic, big pinch roller 33 and small pinch roller 34 are not rotated, and traction cylinder 32 returns to summit and waits next triggering, and so on carries out, no
Disconnected draw lead to lead guider 35 uses for punching inserting mechanism；
At the same time, insert bleed cylinder 45 to start working, drive the slotting set 42 that draws to move downward, insert and draw the band He of active slotting-tool 44 of set 42
Second connecting rod 493 declines simultaneously, and slotting tool 44 is punched downwards, now, due to the pre-pressing force of stopper spring 72 so that block 71 is kept off
Firmly support knife 43 so that will not continue to move downward to knife 43.
When two slotting tools 44 complete the punching work between two adjacent fireworks, while lead is thrust.Due to
The lower hinge of two connecting rods 493 can be slided in the chute 76 of block push rod 74, when sliding into the rear end of chute 76, can be driven
Block push rod 74 is moved backward, pulls open block 71.Now, not by block 71 block support knife 43 by lead be pushed into slotting tool 44 it is firm
In the hole accomplished fluently, complete to insert and draw work.
When the punching inserting mechanism 4 of the present invention works, each working cycles are by two adjacent gun barrels 6 while punching simultaneously
Insert and draw simultaneously, keep two adjacent gun barrels to be connected by lead, so, each gun barrel 6 can be made a call to two holes, each big gun
Cylinder and front and rear gun barrel are all connected by lead.This mode is suitable for the artillery salvo, and the punching of basin big gun etc. form is inserted
Draw work.
In addition, the punching inserting mechanism 4 of the present invention is easy to use, multitool can be extended to, to improve production efficiency.Example
Such as：Double-pole can be changed to by multiple-pin structure by the similar parallel design for punching inserting mechanism；Or local modification punching is inserted
Leading-in device structure, is multiple-pin structure in parallel by double-pole structural modification, realizes multitool and draw while inserting.At the same time it can also according to flower
Big gun is seted off is slowly inserted different kinds of leads soon, i.e., by adjusting the spacing of two lead pinch rollers, to adapt to different-diameter, hardness etc.
The traction requirement of lead.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made.These improvements and modifications also should
It is considered as protection scope of the present invention.
