The specific embodiment

Should know, this paper lays particular emphasis on the encapsulation of gun barrel 006, as for the moulding of gun barrel 006 own, does not repeat them here; The gun barrel 006 here shown in Figure of description 6, is the cylindrical tubular member of moulding, and two ends do not have sealing-in.

Should know simultaneously, gun barrel 006 material used mostly is the multilayer papery according to the general general knowledge of this area, and auxiliary just like plastic sheeting or other material layers, and in some applications or be furnished with prefabricated broken ticker tape, this is known, also is not described in detail at this.

In following method and apparatus, and be not suitable for being bundled into the encapsulation of the firecracker cylinder subgroup of cake, but do not represent that each molding procedure can only complete the encapsulation of a gun barrel 006, obviously, by array, still can satisfy a punching press and complete many gun barrels in the moulding of corresponding station.

The lead end of firecrackers also is called head end or top usually, and the other end is tail end or bottom, can adopt different titles for convenience of describing in different positions in following content.Should know simultaneously, due to the firecrackers bobbin in other words gun barrel 006 it is not distinguished end to end usually as blank, therefore, at one end be also clear and definite in the differentiation of the other end.

A kind of firecrackers method for packing, for gun barrel 006 cylindraceous, its method for packing comprises the following steps:

1) the described gun barrel 006 take an end as foundation location is to guarantee that gun barrel 006 in the scope that the axiality of each station and drift is being scheduled to, also should guarantee easy-unloading with this understanding as much as possible; Moulding other end predetermined length is conical barrel port, and leaves to insert at the vertex of a cone and draw the gap;

Annotate: the predetermined length here refers to the axial length of gun barrel 006, predetermined length how much depend on this end of final sealing-in the time, respective end is extended to radially should sealing-in nozzle and jam-packed lead-in wire, on this basis, test through limited number of time for different gun barrel kinds and all can determine, problem only is to determine relatively difficulty of optimum length.The inventor thinks that time test can be determined a relatively large scope through excellent limit, can be by follow-up checking, as defect rate etc., come gradually to determine better described predetermined length.Those skilled in the art is to be understood that, any technique all can not be known the problem that all need to be revised or face in early stage, usually need to find one by one in production practices and solve, be mostly to determine in production practices for a long time as a certain usable levels of above-mentioned predetermined length.

Have hereinafter the usable levels of correlation values, recommendation and preferred values.Simultaneously those skilled in the art also should be appreciated that the impact that is subjected to as gun barrel papery etc., and some numerical value need to be revised according to workpiece self, in this article, lay particular emphasis on and provide recommendation, but not preferred values more do not lay particular emphasis on and provide optimum value.

2) described insert of coupling drawn the gap and inserts and draw;

Insert draw the gap as if ought to be greater than lead-in wire 005 external diameter, yet, the stroke of conical barrel port, its top is in fact relatively fluffy, going between 005, have must hardness and rigidity, very close to each other even if macroscopic view seems, still can satisfy to insert and draw technological requirement.Therefore, the slotting gap of drawing here, understanding more accurately should be to satisfy lead-in wire 005 structure of inserting, obviously, it is also feasible having the gap of macroscopic view.

In addition, may not stamp out the good slotting gap of drawing of comparison of coherence of rule due to punching press, simultaneously, also should be appreciated that under identical process conditions, slotting uniformity of drawing the gap still can guarantee within the specific limits, even if deviation is arranged, the fluffy vertex of a cone also can satisfy passing through of lead-in wire.Being guaranteed, is exactly the set of lead-in wire, and preferably aided positioning clamping apparatus or miscellaneous part are located lead-in wire, to guarantee carrying out smoothly of subsequent step.

Lead-in wire 005 location has enough spaces 005 to position going between preferably at the other end of gun barrel 006 lead end.

Because lead-in wire 005 has certain rigidity, can keep cylindricality, also can be feasible to its location.

3) the further axial punch of described conical barrel port, increase tapering and make lead-in wire 005 by Primary Location, namely to the 005 formation clamping that goes between; Here increase tapering and can be understood as and go between under this tapering condition and can reliably be located, but not necessarily clamp fully, namely Primary Location; Should be appreciated that simultaneously the state under the certain taper condition keeps owing to wanting filling stuffing and compacting in follow-up step, filler can not spill yet.It is evident that, here tapering is large, has the infinitely-great limiting case of tapering, namely forms the plane.

What be appreciated that further punching press need to guarantee from above explanation is that filler can not spill from this end, and can clamp described lead-in wire 005.And lead end is in most of the cases the plane, can adopt the version of sphere or the conical surface in some cases, should note, fine taper nozzle 002 as shown in Figure 2, its structure is not proper round platform, be not more proper circular cone, but those skilled in the art is to be understood that its version.

About can relating in the distortion content below in gun barrel reducing process, the structure that molds does not have the strict geometry that retrains as taper yet, and those skilled in the art is to be understood that.

4) gun barrel 006 after upset Primary Location lead-in wire 005, and gun barrel 006 lead end is located, facilitate adding of gunpowder, and the encapsulation of bottom;

The lead end of this moment is cylindrical portion, based on this, can select columnar member at the way of restraint of its axial freedom, prevents simultaneously its deflection, therefore preferably adopts external member to locate.

In view of the difficult point that encapsulates is lead end, and due to based on above step as can be known, direct sealing-in bottom after the complete lead end of sealing-in, do not need extra spontaneous curing, make sealing-in difficulty in bottom reduce, therefore, can adopt the sealing-in mode identical with head end to carry out the sealing-in of bottom in the situation that do not consider to go between, also can adopt traditional mode to the bottom sealing-in.

5) perfusion lead end filler and compacting;

6) add gunpowder, sealing-in bottom after the filler of bottom.

Adopt the mode moulding of directed punching press about the moulding of lead end, the method is utilized several mould moldings as shown in Fig. 8-10, taper diel as shown in Figure 9, and its fine taper mould 300 has the taper body, has homing effect., should know, gun barrel 006 is cylinder type for this reason, if not guiding of axial directed punching press can make moulding there is no directionality, it is necessary first molding conical barrel port.But depend on the conical barrel port that molds as fine taper mould 300, its transformation rule uniformity in other words is slightly poor, although gun barrel 006 structure ability of anti-deformation is substantially even, but inconsistent after all, and during punching press, can not guarantee that mould and gun barrel 006 have desirable axiality, simple said structure, percent defective are slightly high.

For this reason, in certain embodiments, accept foregoing description, in step 1) at the moulding other end, and before lead end is taper, also comprise the cylinder section of corresponding described conical barrel port is molded centripetal recessed and extend vertically circumferential uniform pleat groove.Like this, fold can produce stress and concentrate, and then, produces the distortion guide effect, thereby when rushing conical barrel port, can obtain the comparatively shape of rule.

On the other hand, draw step about aforesaid inserting, the conical barrel port of rule relatively of moulding can guarantee to insert carrying out smoothly of drawing, and guarantees carrying out smoothly of follow-up other steps.

The fold moulding is relatively simple, and shape is regular shape as previously mentioned to a certain extent, and other structures have certain arbitrariness relatively.Fold can show as shape nozzle 001 as star-like in polygon in Fig. 1, and its external manifestation is folding groove shape, and more excellent selection is the square groove structure.This structure, it is in the large process of conical barrel port tapering change, and bottom land produces deforming trend, and the conical barrel port of formation is more regular.

Consider directed punching press, be mainly gun barrel 006 axially carry out punching press, the fold here shows certain characteristics, namely fold is less than other parts at the end of pressing direction in the extension of radial direction, is beneficial to the importing of forming part.And this structure more is conducive to the moulding of subsequent step, and obviously, strong the closer to its distortion Shaoxing opera of position of nozzle, this requirement is exactly satisfied in this directed punching press.

Sealing structure for formation rule, described pleat groove should be no less than 3, cross Mold Making difficulty at most and reach, the conical barrel port that more easily molds is even so got over close to circle, but also unnecessary, available pleat groove mostly is 9 most, recommend 5 ~ 7, in recommendation, through experiment, the conical barrel port that molds is rule relatively, and Mold Making is also more convenient.In fact, answer the situation of preferred axes symmetrical structure, therefore, optimal selection should be 6, and the moulding guidance quality is better.

Preferably, the bosom of described pleat groove is less than the interior pore radius of described gun barrel 006.need to prove, the not absolute demand of pleat groove produces pleat groove shape as shown in Figure 1, in certain embodiments, the pleat groove can show as the gun barrel 006 state groove depth structure of linear change from top to bottom as shown in Figure 1, consider resilience, when making corresponding mould, the strong point of this type of mould tooth can be close to the radius of gun barrel 006, but draw in order to insert, actual groove depth maximum should be at the 1/3 interior pore radius of gun barrel 006, in gun barrel, pore radius is designated as r, like this, available groove body H is r/10≤H≤2r/3, recommend r/8≤H≤r/3, when adopting the groove depth structure of linear change as above, the bosom can be slightly large, and flute profile shown in Figure 1, its main body is relatively even, removes the leader of tail end, under these technical conditions, should select more shallow groove depth parameter.

Should be appreciated that above-mentioned linear change, actually more darker near nozzle.

Should consider front and back step and himself intensity after the firecrackers global formation of sealing-in as for the axial length of described pleat groove, available scope is 1.02 ~ 1.50 times of described gun barrel 006 interior pore radius, the difficulty or ease of step before and after considering, if the easier front numerical value of choosing the scope of stating, if consider the intensity of this end, consider the numerical value after above-mentioned scope.Draw as inserting, obviously need to consider the tapering of conical barrel port, draw still can insert than more smoothly under this tapering condition.Therefore, the structure here and the tapering of follow-up conical barrel port can be subject to relative impact, when two groups of parameters are selected, need to consider.

In certain embodiments, for the shape of the conical barrel port that guarantees final molding rule relatively, the described conical barrel port of moulding has two stages, phase I, second stage went out tapering greater than the large conical barrel port 003 of described fine taper nozzle tapering for the basic enterprising one-step shaping at fine taper nozzle 002 in order to mold fine taper nozzle 002.

The tapering magnitude relationship here is a relative concept, has the ordinal relation on operation, and should consider the length of foregoing fold.

Under the impact that weakens fold length, the tapering of the described fine taper nozzle of recommendation is 12:8 ~ 12:5, and the tapering of described large conical barrel port is 12:4 ~ 12:1, two taper value positive correlations in the scope of correspondence in the choice.

The tapering of final large conical barrel port 003 should be as much as possible close to 1:12, convenient final nozzle moulding.

Accept aforesaid content, nozzle can not produce proper in the process of reducing as be conical, because reducing is a concept of macroscopic view relatively, cover excessive, here use conical barrel port to characterize the structure with flared structure, can be namely the structure with equivalent spherical shape, can be also the structure with equivalent circular cone/platform structure.And in deformation process, due to distortion and the disunity of gun barrel self, the taper in design can't produce the taper in ideal, and the variation of this intermediate shape can not produce significant impact to final shape.

Simultaneously, comprising the description of above-mentioned tapering, according to the General Definition of tapering, get the content of its latter half, be characterized by as top defined flared structure, for the ratio of its bottom surface radius with height, is also can be to be understood by the person skilled in the art.

In structure as shown in Figure 4, corresponding, the nozzle of described step 3) final molding is flat nozzle 004.Need to prove, as shown in Figure 4, sit certain distance under the part of flat nozzle 004 in stack shell, the structure that is beneficial to institute's moulding keeps, can show as chamfering or rounding on mould, it is of a size of the length of side of falling the pin or the lower size of sitting can be chosen as 0.5mm ~ 2mm for 10mm gun barrel 006 diameter, and the gun barrel diameter increases or when dwindling, can this scope of positive correlation.

Point out in aforesaid content, the gun barrel bottom can adopt traditional technique to encapsulate, also can further adopt the mode that this paper proposes to encapsulate, to guarantee the continuity of technique, in step 6) after bottom filling and compacting after, this end nozzle is reserved with the cylinder section of 1.1 ~ 1.5 times that length is gun barrel 006 interior pore radius, by directed punching press, stamps out tapering until punching is put down and sealing-in.Here not only consider the lumber recovery in forming process, and it is broken and affect the final effect of firecrackers to consider to place in transportation bed mud.

Preferably, in step 1), the locate mode of described gun barrel 006 is to the end face location of gun barrel at this end take an end as foundation location, and assisting has the cylinder 103 that is inserted in the gun barrel endoporus from this other end, and reserve profiled section at this another section end, be conducive to not to the utmost moulding, and can keep the stability of gun barrel 006, and the nozzle root edge that molds is more regular.
