Fig. 2 is the 3-D view of the cutter of one embodiment of the invention.
Embodiment
Detail is elaborated in the following description in order to fully understand the present invention.But the present invention can with it is a variety of not Other manner described here is same as to implement, those skilled in the art can do class in the case of without prejudice to intension of the present invention Like popularization.Therefore, the present invention is not limited by following public embodiment.
The structure composition of the present invention is described further below in conjunction with the accompanying drawings.
To realize the lightweight of cutter, miniaturization, the design creation for follow-up connection tripper is more favorably set Count space.The present invention provides a kind of cutter, including initiator 1, body 2, detonator 4, O-ring 5, back-up ring 6, cutting knife 7, locking Screw 8, knife anvil 9 form, for cutting thing to be cut.
Optionally, the cutting knife 7 is equipped with cutting edge with knife anvil 9, forms two-sided cutting form collective effect in thing to be cut.
Optionally, the end face of knife anvil 9 is provided with skewed slot, for collecting caused fifth wheel after cutter works.
Optionally, in addition to positioned at the outside of detonator 4 steel bushing 3 set, for strengthening main detonation area carrier ability.
Optionally, the cutting knife 7 is fixed by the lock-screw 8, and after being connected to work order, the initiator 1 produces quick-fried Hong ripple, the detonation wave saequential transmission quirk detonating primer 4, detonator 4 produce detonation wave after igniting and promote cutting knife 7, lock-screw 8 is cut It is disconnected, carry out cutting thing to be cut to the movement progress of knife anvil 9.
Optionally, the O-ring 5 and back-up ring 6 are located at the surface of cutting knife 7, for fixing the cutting knife 7 so that cutting knife 7 is cut During promoted along predefined paths.
Optionally, the detonator 4 is located at the side of the cutting knife 7, i.e., between the cutting knife 7 and the initiator 1.
Optionally, the knife anvil 9 is located at the opposite side of cutting knife 7.
Optionally, the initiator 1 is connected to the side of body 2, for producing detonation wave saequential transmission quirk detonating primer 4, for promoting the cutting knife 7.
Optionally, before cutter work, the cutting knife 7 screw 8 that is locked is fixed, described when cutter works Cutting knife 7 cuts lock-screw 8.
Optionally, the thing to be cut is titanium bar.
Optionally, the body 2 of the cutter uses integrated design.
The invention discloses a kind of new cutter, by carrying out firer's component parameters design optimizing, bearing structure Design optimizing, motion design optimizing etc. are studied, breakthrough light-high-strength high rigidity restraining structure designing technique, The key technologies such as motion Miniaturization Design technology, fifth wheel control technology, realize that the lightweight of cutter, miniaturization are set Meter, there is outstanding advantages of simple in construction, in light weight, small volume, high reliability.
As shown in Figure 1 and Figure 2, cutter is mainly by initiator 1, body 2, steel bushing 3, O-ring 5, back-up ring 6, cutting knife 7, lock The compositions such as tight screw 8, lock-screw 8.Before cutter work, the screw 8 that is locked of cutting knife 7 is fixed, and after being connected to work order, is risen The quick-fried work of device 1 produces detonation wave saequential transmission quirk detonating primer 4, and detonator 4 produces detonation wave and promotes cutting knife 7 by locking screw after detonating Nail 8 is cut to knife anvil 9 and moves cut-out titanium bar 11.
The present invention key technology and innovative point be:Cutting knife 7 is equipped with cutting edge with knife anvil 9, forms two-sided cutting form and is total to Same-action improves cutter operating efficiency in titanium bar 11;The end face of knife anvil 9 is provided with skewed slot, collects caused by after cutter work Fifth wheel;The outside of detonator 4 sets steel bushing 3, strengthens main detonation area carrier ability;The work of initiator 1 produces detonation wave saequential transmission fire Road detonating primer 4, detonator 4 produce detonation wave and promote cutting knife 7 to move cut-out titanium bar 11 to knife anvil 9 after detonating;Torch body 2 is adopted With integrated design, annexation is reduced, mitigates this body weight.
After the cutter is connected to work order, initiator work produces detonation wave saequential transmission quirk detonating primer, and detonator rises Detonation wave is produced after quick-fried promotes cutting knife to move cut-out titanium bar to knife anvil.It is horizontal with reference to integrated stress for cutter operation principle Optimize housing outer casing thickness;Main detonation area selects high intensity rigid material;Cutter shell uses integrated design, reduces cutting Device profile, mitigate cutter weight.
