As Fig. 1～shown in Figure 4, connector 21 of the present invention is made up of pipe 24, a side connecting pin 22 and opposite side connecting pin 23.Especially will be at the width of watchband 25 when a relative lateral edges chain piece 26 is connected with opposite side boundary chain piece, use 2 metal connecting pins 22,23.
One side connecting pin 22 has elongate cylinder oblique crank Z 22a.End at axle 22a is provided with the cylindrical head 22b thicker than axle 22a.That is be M, then L＜M, if the external diameter of establishing a 22a is the external diameter of L, head 22b.
Form the inclined plane 22c of truncated cone at the position of head 22b near axle 22a.That is, between axle 22a and the head 22b through mild inclined plane 22c and continuous.In addition, the protruding 22d of truncated cone from the head the open end of 22b rise along the length direction of axle 22a and protrude.
Opposite side connecting pin 23 has the axle 23a shorter than the axle 22a of a side connecting pin 22.And same with a side connecting pin 22, each self-forming head 23b, inclined plane 23c and protruding 23d on axle 23a.
Above-mentioned connecting pin 22,23 can be produced in enormous quantities at low cost continuously with automatic cutter.
In addition, also be provided with metal hollow cylinder, promptly pipe 24.As shown in Figure 4, the internal diameter of pipe 24 is greater than the external diameter L of axle 22a, the 23a of connecting pin 22,23, and less than the external diameter M of head 22b, 23b.That is, if the internal diameter of establishing pipe 24 is N, L＜N＜M then.
An above-mentioned side connecting pin 22, opposite side connecting pin 23 and pipe 24 constitute connector 21.One lateral edges chain piece 26 has at the relative end that has of the width of watchband 25 with opposite side boundary chain piece 27 and is connected blind hole 28,29.Medial surface at a lateral edges chain piece 26 wears connecting hole 28, wears connecting hole 29 at the medial surface of opposite side boundary chain piece 27.Owing to be to use bit bore, connecting hole 28,29 bottom surface 28b, 29b separately is taper shape.
As shown in Figure 4, the internal diameter Q of connecting hole 28,29 is greater than the external diameter P1 of pipe 24, and as described later, head 22b, the 23b of connecting pin 22,23 is pressed in the pipe 24, and pipe 24 is less than the external diameter P2 of the enlarged portion 24a that forms after the radial dilatation, 24b (Fig. 3).Be P1＜Q＜P2.
Here, the degree of depth of establishing the deep end from peristome 28a, the 29a of connecting hole 28,29 to bottom surface 28b, 29b is R, and then the length (S+T) of degree of depth R after than the length T addition of the length S of head 22b, the 23b of connecting pin 22,23 and protruding 22d, 23d is also dark.That is R＞(S+T).
Above-mentioned connector 21 is fixed through following number of assembling steps with boundary chain piece 26,27.The wherein so-called above-below direction that is meant up and down in Fig. 5～19.
Step 1
At first as shown in Figure 5, with suitable anchor clamps (not shown) a lateral edges chain piece 26 is remained on the upper side that holds mould 31.Connecting hole 28 upward openings of one lateral edges chain piece 26.Similarly use anchor clamps (not shown) that connection chain piece 30 is remained on the lateral edges chain piece 6 again.At this moment, the connecting hole 30a that connects connection chain piece 30 is alignd with connecting hole 28.The internal diameter of connecting hole 30a also can be identical with the internal diameter of connecting hole 28, but preferably as scheming greater than the internal diameter of connecting hole 28.
Step 2
Then as shown in Figure 6, the opening that makes progress from the connecting hole 30a of connection chain piece 30 inserts a side connecting pin 22.The connecting pin 22 of one side must insert head 22b downwards.The head 22b of connecting pin 22 insert in the connecting hole 28 of boundary chain piece 26 and with bottom surface 28b butt.Specifically, be the front end of protruding 22d of head 22b and the inclined-plane butt of bottom surface 28b, the moving axially of restriction connecting pin 22.
Because R＞(S+T), so the head 22b of connecting pin 22 entirely submerges in the connecting hole 28.In addition, the axle 22a of connecting pin 22 exposes from the opening of the connecting hole 30a of connection chain piece 30.Like this, connecting pin 22 just is communicated with connecting hole 30a with connecting hole 28.
Step 3
Then as shown in Figure 7, from the opening of the connecting hole 30a of connection chain piece 30 from last insertion pipe 24.The axle 22a of the connecting pin 22 of before having packed into passes in the pipe 24.Because N＜M is so pipe 24 is inserted into the peristome edge of pipe 24 1 ends and the inclined plane 22c butt of connecting pin 22 always.The pipe 24 that connecting hole 30a is communicated with connecting hole 28 encases the axle 22a of connecting pin 22, arrives near the opening of connecting hole 30a of connection chain piece 30.Perhaps also can expose upward from the opening of connecting hole 30.The axle 22a of connecting pin 22 then submerges in the pipe 24 fully.The open end of axle 22a does not stretch out from the other end peristome of pipe 24.
Because P1＜Q, so allow pipe 24 to rock at connecting hole 30a and connecting hole 28 inner radial.Again owing to L＜M＜Q, so allow the head 22b of connecting pin 22 and axle 22a to rock in pipe 24 inner radial (horizontal among the figure).
Then as shown in Figure 8, the other end peristome of the pipe 24 that stretches out upward at the connecting hole 30a from connection chain piece 30 inserts the axle 23a of opposite side connecting pin 23 with a gap.Because L＜M＜Q, so have only a 23a to insert pipe 24 inside with a gap, head 23b is protruding from pipe 24.At this moment, the inclined plane 23c butt of the peristome edge of pipe 24 other ends and connecting pin 23.Allow axle 23a to rock in pipe 24 inner radial.
Step 5
Then as shown in Figure 9, be ready to the boundary chain piece 27 of opposite side.The head 23b of connecting pin 23 is inserted in the connecting hole 29 of boundary chain piece 27.With suitable anchor clamps (not shown) boundary chain piece 27 is remained on the top of connection chain piece 30 again.Here, connecting hole 28, connecting hole 30a and connecting hole 29 are arranged on same the straight line.
At this moment, between the open end of axle 22a in inserting pipe 24 and axle 23a, leave later step 26 desired enough space A.The length W (see figure 4) of pipe 4 must be the non-touching size of open end that makes a 22a, axle 23a.
At this moment, inserted near the peristome of connecting hole 29 that space A between the open end of axle 22a, 23a in the pipe 24 preferably is positioned at boundary chain piece 27.Specifically, space A is positioned at the outside slightly of the peristome of connecting hole 29.
Preferably in advance the other end edge of pipe 24 is inserted in the connecting hole 29 of boundary chain piece 27 this moment.
Then as shown in figure 10, pressing mold 23 pushes boundary chain piece 27 downwards.Make boundary chain piece 27 along the vertical direction near boundary chain piece 26.
So, the head 23b of connecting pin 23 just with the bottom surface 29b butt of the connecting hole 29 of boundary chain piece 27.Be the front end of protruding 23d of head 23b and the inclined-plane butt of bottom surface 29b specifically, the moving axially of restriction connecting pin 23.Because R＞(S+T), so the head 23b of connecting pin 23 entirely submerges in the connecting hole 29.
At this moment, as shown in figure 11, the inclined plane 22c butt of pipe 24 openings at two ends portion edges and connecting pin 22.Allow axle 22a to rock in pipe 24 inner radial.
Equally, as shown in figure 12, each inclined plane 23c butt of pipe 24 openings at two ends portion edges and connecting pin 23.Allow axle 23a to rock in pipe 24 inner radial.
Step 7
Then as shown in figure 13, pressing mold 32 is with further pushing downwards of boundary chain piece 27, and boundary chain piece 27 is along the vertical direction more near boundary chain piece 26.So, because L＜N＜M, so as shown in figure 14, the peristome edge of pipe 24 1 ends is along the inclined plane 22c expansion of connecting pin 22.Equally, as shown in figure 15, the peristome edge of pipe 24 other ends is along the inclined plane 23c expansion of connecting pin 23.
Then as shown in figure 16, pressing mold 32 is with further pushing downwards of boundary chain piece 27.So, the head 22b of connecting pin 22 is pressed into pipe 24 inside from the peristome of pipe 24 1 ends.The head 22b of connecting pin 22 is engaged with pipe 24 crimping.
As shown in figure 17, one edge, the peristome edge inclined plane 22c of pipe 24 1 ends expansion is Yi Bian encase the outside of the head 22b of connecting pin 22.Thereby owing to being pressed into of head 22b, pipe 24 forms the enlarged portion 24a that expands outwardly.At this moment, because P1＜Q＜P2, so the outer peripheral face of enlarged portion 24a engages with the internal perisporium crimping of the connecting hole 28 of boundary chain piece 26.
Equally, the head 23b of connecting pin 23 is pressed into pipe 24 inside from the peristome of pipe 24 other ends.The head 23b of connecting pin 23 is engaged with pipe 24 crimping.
As shown in figure 18, pipe 24 other end peristome edge one edge inclined plane 23c expansion Yi Bian encase the outside of the head 23b of connecting pin 23, forms enlarged portion 24b.The outer peripheral face of enlarged portion 24b is engaged with the internal perisporium crimping of the connecting hole 29 of boundary chain piece 27.Pipe 24 is fixed on the boundary chain piece 27 like this reliably.
So connector 21 just is fixed on boundary chain piece 26 and the opposite side boundary chain piece 27.Rotating shaft with the connector 21 double as connection chain pieces 30 of boundary chain piece 26 and 27 bridge joints.
At this moment, shown in Fig. 3,17,18, enlarged portion 24a, 24b are preferably in than forming near the position darker connecting hole 28,29 peristome separately.And preferably keep initial internal diameter Q near connecting hole 28,29 peristome separately.
In addition, enlarged portion 24a, 24b are preferably in connecting hole 28,29 inside separately and fully expand, and keep the external diameter P2 greater than the internal diameter Q of connecting hole 28,29.
So, since the external diameter of enlarged portion 24a, 24b greater than near the internal diameter the peristome of connecting hole 28,29, so enlarged portion 24a, 24b will not deviate from from the peristome of connecting hole 28,29.Thereby guaranteed the secure fixation of 26,27 of connector 21 and boundary chain pieces.
In order to form enlarged portion 24a, 24b near the position darker than connecting hole 28,29 peristome separately, to accomplish R＞(S+T) at least.
In addition, near connecting hole 28,29 peristome separately, keeping initial internal diameter Q, near above-mentioned peristome,, also must not form enlarged portion 24a, 24b even temporary transient.Even enlarged portion 24a, the 24b that will form in the outside of connecting hole 28,29 are pressed in the connecting hole 28,29, the internal diameter Q of above-mentioned peristome also can enlarge.
Step is described as described above, and a near manufacture process that only on the darker position head 22b, the 23b of connecting pin 22,23 is pressed into than above-mentioned peristome in the pipe 24 must be arranged.
In addition, on watchband 25, for enlarged portion 24a, 24b are fully expanded in connecting hole 28,29 inside separately, make it have external diameter P2 greater than internal diameter Q, pressing mold 32 will apply 60 kilograms pressure at above-below direction at least.
At this moment, the open end that has inserted axle 22a, 23a in the pipe 24 is preferably in than approaching mutually with the gap less than space A on the slightly outer position of the peristome of the connecting hole 29 of boundary chain piece 27.Perhaps, the open end of axle 22a, 23a preferably is in contact with one another.In order to accomplish this point, the axle 22a that is fixed on the connecting pin 22 in the connecting hole 28 of boundary chain piece 26 must have near the length the connecting hole 29 that can arrive boundary chain piece 27.
Thus, even boundary chain piece 26,27 and connection chain piece 30 are oppositely pullled each other, pipe 24 can be not crooked yet.So just make watchband 25 possess the pulling force that enough intensity is born length direction.
In step 6～8, the pushing force of pressing mold 32 might make in the pipe 24 and bend or fracture near the residing position B of space A (Figure 13).This is because this position does not have the supporting of axle 22a, the 23a of connecting pin 22,23.
Yet,, can avoid the crooked of above-mentioned pipe 24 or fracture if the position B of pipe 24 is positioned near the peristome of connecting hole 29 of boundary chain piece 27 in step 5.This is because the inwall of connecting hole 29 has supported pipe 24, can prevent that it is crooked or fractures.
In addition, if near step 5 makes the other end of pipe 24, insert in the connecting hole 29 of boundary chain piece 27, then in step 7 and 8, pipe 24 can be inserted in the connecting hole 29 reliably.And the head 23b of connecting pin 23 can not be pressed in the pipe 24 near the peristome of connecting hole 29.
Poor (P2-Q) of the external diameter P2 of the bed knife between connector 21 and the boundary chain piece 26,27 and enlarged portion 24a, the 24b of pipe 24 and the internal diameter Q of connecting hole 28,29 is proportional.(P2-Q) proportional with the internal diameter N of the external diameter M of head 22b, the 23b of connecting pin 22,23 and pipe 24 poor (M-N).
And the bed knife that connector 21 and boundary chain piece are 26,27 and head 22b, the 23b of connecting pin 22,23 be the length S, in more detail of direction along the axial length, is proportional with the length T that is pressed into head 22b, 23b in the pipe 24.If head 22b, the 23b of connecting pin 22,23 entirely are pressed in the pipe 24, then S=T.
In addition, the load that applies of pressing mold 32 is also influential.
In case (M-N) and T excessive, in abovementioned steps 6～8, the danger that A residing position in space bends or fractures on the pipe 24 will increase.On the contrary, if too small, then the bed knife of 26,27 of connector 21 and boundary chain pieces is also little, can cause connector 21 to be deviate from from boundary chain piece 26,27.
Therefore, (M-N) and S preferably be set in the suitable scope.
The scope of the M value of watchband 25 is preferably 0.50～1.50mm, be more preferably 0.80～0.95mm, 0.85～0.90mm preferably, the scope of N value is preferably 0.50～1.50mm, be more preferably 0.80～0.95mm, preferably 0.82～0.86mm (M-N) is preferably 0.10～0.80mm, be more preferably 0.20～0.60mm, preferably 0.4mm.
The scope of the T value of watchband is preferably 0.20～1.00mm, is more preferably 0.40～0.80mm, preferably 0.6mm.
For above embodiment, the insider also can do various changes and append.
For example, the head 22b of above connecting pin 22,23, the external diameter of 23b are M, become various outer diameter but also can set in the scope that can obtain held stationary power.About the external diameter L of axle 22a, 23a, the axial length S of head 22b, 23b also is like this.The internal diameter Q of the connecting hole 28,29 of boundary chain piece 26,27 also not necessarily will equate.
In addition, also the part of head 22b, the 23b of connecting pin 22,23 can be pressed in the pipe 24.At this occasion, S＞T.
In addition, head 22b, the 23b of connecting pin 22,23 also can not establish protruding 22d, 23d.
In addition, connection chain piece 30 is not limited to 1.Also can be as shown in figure 19, also 2 connection chain piece 30A can be arranged above and below with 30B is connected with connector 21.Also can use more connection chain piece.
In addition,,, be not limited to above-mentioned step, can consider other various assemble methods for the state of completing steps 5 in the assembling stage.

In addition, also pipe 24 and connecting pin 22,23 can be assembled in advance.That is, axle 22a, the 23a of connecting pin 22,23 relatively inserted in the pipe 24 from the both ends open portion of pipe 24 respectively, and head 22b, 23b are stretched out to the outside of pipe 24.At this moment, if connecting pin 22,23 is pressed in the pipe 24 slightly, make the peristome edge crimping gently of inclined plane 22c, 23c and pipe 24, then connecting pin 22,23 just can not deviate from from pipe 24, so very convenient.
Second embodiment
Below in conjunction with Figure 20, the 21 explanation second embodiment of the present invention.
Figure 20 is the biopsy cavity marker devices vertical view of the belt decorative product of second embodiment of the invention, and Figure 21 is the local amplification view of enlarged portion of the belt decorative product of Figure 20.All structures identical with first embodiment are all represented with same-sign, and detailed, and difference only is described.
As shown in the figure, the difference of the connector 21 of second embodiment and first embodiment is the length of connecting pin 32 and connecting pin 33.
That is, connecting pin 32 is shorter.The axle 32a of connecting pin 32 at the total length U of length direction less than the peristome 28a of connecting hole 28 degree of depth R to the deep end of bottom surface 28b.Be U＜R.
Like this, it is just correspondingly elongated that the part of connecting pin 32 shortenings just makes connecting pin 3.The length of the axle 33a of connecting pin 33 after the total length of length direction equals the total length addition of connecting pin 22,23 of connector 21 from first embodiment deducts the total length U of connecting pin 32.As shown in figure 20, the total length of connecting pin 33 has the sufficient length of boundary chain piece 26,27 being carried out bridge joint through connection chain piece 30.
Above-mentioned connector 21 is fixed through the number of assembling steps identical with first embodiment with boundary chain piece 26 and boundary chain piece 27.
So, as shown in figure 21, connecting pin 33 is inserted into connecting hole 28 inside of boundary chain piece 26.Thereby the danger that can get rid of connector 21 bendings or fracture.
When adopting first and second embodiment, the fixture that is made of boundary chain piece and connector can obtain the bed knife of firm stable by the crimping of pipe, and the crimping between the connecting hole of connector and boundary chain piece can not relax.Thereby, can obtain can not taking place the belt decorative product that connector breaks away from boundary chain piece phenomenon.
Figure 22 is the stereogram of the connecting pin structure of expression third embodiment of the invention.Connecting pin 42 is processed by pole stock, has axial region 42a and establishes at one end head 42b.Axial region 42a is columniform rigid body, and for the ease of inserting the connecting hole of chain piece, its front end (left end among the figure) forms the thin inclined-plane 42c in front side towards end face 42d.The diameter of head 42b is greater than axial region 42a, forms joint-cutting 42f vertically from the central portion of its end face 42e.Outer peripheral face at this head 42b is provided with: at crimping face 42g, the inclined-plane 42h that forms between crimping face 42g and axial region 42a for ease of insertion of the connecting hole inwall crimping of its substantial middle and chain piece, the inclined-plane 42i that forms around end face 42e for ease of releasing from connecting hole.And the slightly larger in diameter of head 42b is in the connecting hole 36d of chain piece (Figure 23).In addition, as shown in the figure, not only on head 42b, on axial region 42a, also form joint-cutting 42f.
Below in conjunction with Figure 23 the state that connects the chain piece of watchbands with usefulness connecting pin 42 shown in Figure 22 is described to Figure 26.Figure 23 and watchband 34 shown in Figure 24 are made of boundary chain piece 36 and connection chain piece 38, and the connection chain piece is the rectangle ring bodies as shown in figure 24.Fixing connecting plate 36c between boundary chain piece 36, connection chain piece 38 surrounds its installation.On this watchband, for connection chain piece 38 being connected with adjacent boundary chain piece 36 with connecting pin 42, each chain piece to be positioned to the state that connecting hole 36d, the 36e of boundary chain piece 36 are communicated with the connecting hole 38a of connection chain piece 38, and connecting pin 42 is inserted connecting hole 36d, 36e, 38a.At this moment, connecting pin 42 inserts connecting hole 36d, 36e, 38a from end face 42d one side of its axial region 42a, and the front end of axial region 42a and head 42b successfully insert owing to their inclined-plane 42c, 42h, and the opening portion that can not be connected hole 36d, 36e, 38a hooks.
Because the diameter of the head 42b of connecting pin 42 is greater than connecting hole 36d, so insert in the connecting hole 36d radially being compressed.And this head 42b utilizes its elasticity and with the inwall that crimping face 42g is crimped on connecting hole 36d, connecting pin 42 is fixed in connecting hole 36d, 36e, the 38a.Because the diameter of axial region 42a is less than connecting hole 38a, the earth's axis is bearing on the axial region 42a so connection chain piece 38 rotates freely.
In case with connecting pin 42 connection chain piece 38 is connected with boundary chain piece 36 as described above, the axial region 42a of the connecting pin 42 that intensity is high promptly supports connection chain piece 38 and chain piece 36, even the tension force of oriented watchband length direction applies, connecting pin 42 can not deform or fracture yet, and can realize high-intensity connection.
In the time of connecting pin 42 will being taken out for the reconciliation statement strip length, utilize the end face 42d of pushing connecting pin 42 such as instrument, just head 42b can be taken off from connecting hole 36d release.
As mentioned above, connecting pin 42 can be used for the watchband of various structures and shape, but also can be used for connecting snap-fit feature.For example, as shown in figure 27, on the hasp 60 of three folded structures that constitute by surface plate 62, middle plate 64 and lower plate 66, can the part of chain piece 68 that connects watchband one end and surface plate 62, be connected surface cover 62 and middle plate 64 part, be connected in plate 64 and lower plate 66 part and be connected lower plate 66 and the part of the chain piece 70 of the watchband other end is connected with connecting pin 42 respectively.That is, connecting hole 62c, 62d on sidewall 62a, the 62b of surface plate 62 are communicated with connecting hole 68a, the 68b of chain piece 68, and insert connecting pin 42 therein.In addition, connecting hole 64c, 64d in tube 64a, the 64b of other connecting hole 62e, 62f and middle plate 64 1 ends on sidewall 62a, the 62b of surface plate 62 are communicated with, and insert connecting pin 42 therein.Interior connecting hole 66c, the 66d of connecting hole 64f in making again in the tube 64e of plate 64 other ends and tube 66a, the 66b of lower plate 66 1 ends is communicated with, and inserts connecting pin 42 therein.Interior connecting hole 66g, the 66h of tube 66e, 66f of lower plate 66 other ends is communicated with the connecting hole 70a of chain piece 70, and inserts connecting pin 42 therein.
No matter in above-mentioned which coupling part, the diameter of the axial region 42a of connecting pin 42 all is less than connecting hole, and with the rotatable earth's axis supporting of each, the diameter of head 42b utilizes the inner face crimping of its elasticity and connecting hole then greater than connecting hole.
Example when Figure 28 represents to be used to connect watchband and table main body.
As shown in the figure, when the watchband 74 that leather or rubber etc. make is installed between connecting pin 72a, the 72b of table main body 72, connecting hole 72c, the 72d of connecting pin 72a, 72b is communicated with the connecting hole 74a of watchband 74 ends, and inserts connecting pin 42 therein.
In addition, as shown in figure 29, when being installed to from installation portion 76a that table main body 76 protrude with 78 metal tabulation, the connecting hole 72b of installation portion 76a being communicated with connecting hole 78b, the 78c of chain piece 78, and inserting connecting pin 42 therein.
The connecting pin that is used for the chain piece that watchband need not to regulate the length part, the submersion watch that uses, hasp etc. under rigor condition requires firmly to connect, difficult drop-off.
Figure 29 represents to be used for the connecting pin of this class occasion.As shown in the figure, connecting pin 42A is provided with head 42b at the two ends of its axial region 42a.Two head 42b are identical with the head 42b structure of connecting pin 42 shown in Figure 22, radially have elasticity owing to be provided with joint-cutting.
When being provided with the connecting pin 42A connection chain piece of head 42b with this two ends, as shown in figure 29, each head 42b clips the inwall crimping of connecting hole 78c, 78d of two chain piece 78a of central chain piece 78d with two ends from the watchband width with regard to utilizing its elasticity, in the time of it will being extracted, will be than the power of the connecting pin more than 42 that has only a head 42b with one times.And, even chain piece 78 on one side from the head 42b extract, just not can not come off as long as head 42b does not on one side pass the connecting hole 78e of connection chain piece 78d, so unless with taking-ups such as instruments, otherwise can not come off.
When using two ends that the connecting pin 42 of head 42b is arranged as described above, also connecting hole 78b, the 78c that can the connecting hole that is located on the chain piece 78a not made as shown in figure 29 connects the through hole of chain piece 78 like that, but makes as shown in figure 30 blind hole 78f, 78g.By making blind hole, the head 42b of connecting hole 78f, 78g and connecting pin 42A just can not appear in the watchband side, helps improving the aesthetic property of watchband.In addition, the edge that also can avoid being exposed to the connecting hole opening portion of watchband side chafes wrist, make wear more comfortable.
The manufacture method of connecting pin 42 below is described.In the present embodiment, but be to forge the profile that forms connecting pins 42 with pole stock shown in Figure 31 80 and fixed die shown in Figure 32 82 and dynamic model 84.This pole stock 80 be stainless steel make cylindrical, fixed die 80 have the axial region formation 82a of portion of the profile of the axial region 42a that forms connecting pin 42, the end face 42d that forms axial region 42a and inclined-plane 42c axial region end face formation 82d of portion and the 82c of axial region inclined-plane formation portion, form the 82h of head inclined-plane formation portion of the inclined-plane 42h of head 42b.The axial region end face formation 82d of portion is made of the end face that is located at the scotch 86 in the fixed die 82.But 84 internal diameters that have greater than the 82a of formation portion of dynamic model have crimping face 42g, the end face 42e of the head 42b that forms connecting pin 42 respectively and the crimping face formation 84g of portion, the head end formation 84e of portion and the 84i of head inclined-plane formation portion of inclined-plane 42i.
At first as shown in figure 33, pole stock 80 is embedded in the fixed die 82, but then exert pressure to pole stock 80 along direction shown in the arrow among Figure 34 88, pole stock 80 is pressed into the shape of connecting pin 42 with dynamic model 84.Then, preferably the connecting pin 42 that will so forge formation is carried out milled processed such as barreling.Grind by this, can remove the burr or the distortion that on connecting pin 42, produce in the forging process, make connecting pin 42 smooth surfaces.So not only can improve the aesthetic property of connecting pin 42, and can avoid connecting pin 42 to wipe and bump, connecting pin 42 successfully can be inserted in the connecting hole with the inwall of connecting hole.On head 42b, form joint-cutting 42f by machining then.
But said fixing mould 82 and dynamic model 84 are that the profile with connecting pin 42 roughly is divided into axial region 42a and head 42b forms, but also can form big portion with fixed die 82 as Figure 35 and shown in Figure 36.That is the axial region formation 82a of portion, the axial region end face formation 82d of portion, the 82c of axial region inclined-plane formation portion, the crimping face formation 82g of portion and the 82h of head inclined-plane formation portion of inclined-plane 42h of crimping face 42g, the head 42b of the axial region 42a, its end face 42d that form connecting pin 42 respectively and inclined-plane 42c, head 42b, is set in fixed die 82.And but the end face 44e of the head 42b that forms connecting pin 42 and head end formation 84e of portion and the 84i of head inclined-plane formation portion of inclined-plane 44i be set on dynamic model 84.
Also can be as Figure 37 and shown in Figure 38, but remove the head inclined-plane 84i of formation portion from dynamic model shown in Figure 34 84, a head end that is made of the plane only is set forms the 84e of portion.But when forming the profile of connecting pins 42 with Figure 37 and fixed die 82 shown in Figure 38 with dynamic model 84, size is the most stable.
But Figure 32 also can be an inverted configuration to fixed die shown in Figure 38 82 and dynamic model 84, but promptly fixed die 82 as dynamic model, but and handle dynamic model 84 as fixed die.
In case by axial pressure pole stock 80 is made the profile of connecting pin 42 as described above, just can improve hardness.For example when pole stock 80 used hardness as the SUS304 material of HV230, the hardness of connecting pin 42 can be brought up to HV about 440.
By improving hardness as described above, its axial region 42a opposing from horizontal, to act on its intensity of force radially just very high.The connecting pin 42 of the present embodiment that table 1 expression is for example made with same material and the transverse strength contrast of the hair fastener shape connector 4 of conventional art.
Table 1
| The pressurization number of | Connecting pin | 42 | | |||
| Recoverable plus-pressure Kg | Plus-pressure Kg during distortion | Recoverable plus-pressure Kg | Plus-pressure Kg during distortion | |||
| 1 | 6.5 | 9.0 | 1.5 | 3.0 | ||
| 2 | 6.5 | 8.5 | 2.0 | 3.0 | ||
| 3 | 6.5 | 9.0 | 2.0 | 2.5 | ||
| 4 | 5.5 | 9.0 | 2.0 | 2.5 | ||
| 5 | 5.5 | 8.5 | 2.0 | 2.5 | ||
As shown in table 1, connecting pin 42 opposings are roughly 2～3 times of connector 4 from horizontal intensity of force.
On the other hand, the connecting pin of the machining manufacturing by automatic lathe etc. and with the connecting pin of forging processing and manufacturings such as punch press from being easy to difference in appearance.That is, the outer surface of the connecting pin of machining leaves revolution mark.And the outer surface of connecting pin that forges processing does not have this class revolution mark near joint-cutting.Especially, if the connecting pin that forges processing is imposed aforesaid barreling, then the outer surface of this connecting pin is quite smooth, so difference is more obvious.
On the connecting pin 42 that forms with above-mentioned forging method, form axial joint-cutting 42f at its head 42b.The external diameters of the size of this axial joint-cutting 42f and head 42b etc. together determine to make the flexible power of crimping face 42g crimping, and the size of each one is preferably set with following condition and scope during with symbolic representation shown in Figure 39.
As shown in figure 39, if the axial depth that the external diameter of head 42b is the opening of L, joint-cutting 42f is spaced apart M, joint-cutting 42f is the internal diameter of the connecting hole 92 of N, chain piece 90 is that the crimping face 42g of area of the inwall crimping of K, decision crimping face 42g and connecting hole 92 is P in axial length, then head 42b is determined by (L-K) to radially elastic deformation amount, the flexible power of the inner face crimping of the crimping face of making 42g and connecting hole 92 is by (L-M) and (N) decision, and the crimping area of crimping face 42g is determined by (P).That is, (L-K) set greatly more, the elastic deformation amount increases, so connecting pin 42 is difficult for coming off from connecting hole 92.In addition, (L-M) and (N) set greatly more, elasticity increases, so connecting pin 42 same difficult drop-offs.Have, (P) set greatly more, the crimping area of crimping face 42g is big more, so connecting pin 42 same difficult drop-offs.Yet if connecting pin 42 is excessive for the crimp force of connecting hole 92, plastic deformation may take place in head 42b.On the contrary, if (L-K), (L-M), (N) and size (P) set too smallly, then connecting pin 42 is too small for the crimp force of connecting hole 92, and connecting pin 42 may come off from connecting hole 92 in careless.Therefore, preferably (L-K), (L-M), (N) and size (P) are set in the scope of certain regulation.
For this reason, be preferably in the interior above-mentioned elastic deformation amount (L-K) of setting of scope of 0.6～0.05mm.When especially deflection being set greatly, be preferably in the scope of 0.6～0.4mm and set, set hour, be preferably in the scope of 0.2～0.05mm and set.
In addition, be preferably in the interior flexible power (L-M) of setting of scope of 4.0～0.3mm.When especially elasticity is set by force, be preferably in interior setting of scope of 0.6～0.4mm, when setting more weakly, be preferably in interior setting of scope of 1.0～0.3mm.
In addition, be preferably in the interior flexible power (N) of setting of scope of 5.0～0.3mm.When especially elasticity is set by force, be preferably in interior setting of scope of 6.0～4.0mm, when setting more weakly, be preferably in interior setting of scope of 1.5～0.3mm.
In addition, be preferably in the interior crimping area (P) of setting crimping face 42g of scope of 6.0～0.2mm.When especially crimp strength is set by force, be preferably in interior setting of scope of 6.0～4.0mm, when setting more weakly, be preferably in interior setting of scope of 2.0～0.2mm.
Even improved intensity as described above and then suitably set flexible connecting pin 42 and inserted in connecting hole repeatedly and extract, the elasticity of head 42b can extremely not die down yet.The variation example of withdrawal force when extracting is inserted in table 2 expression repeatedly in the connecting hole of watchband.
Table 2
| The number of occurrence | Withdrawal force Kg |
| 1 | 3.0 |
| 2 | 2.8 |
| 3 | 2.2 |
| 4 | 2.3 |

| 6 | 2.1 |
| 7 | 2.0 |
| 8 | 2.0 |
| 9 | 2.3 |
| 10 | 2.0 |
As shown in table 2, the variation of withdrawal force is minimum, inserts repeatedly and extracts, and head 42b can not follow the string yet.
When adopting the 3rd embodiment, the axial region that is vulnerable to external force most is to make with rigid body, and makes head have fixing required strong elasticity, so can realize the structure that intensity is high, prevents and is out of shape or fractures.
Owing to be to make the connecting pin with said structure by forging, so can improve its hardness, intensity is high, the elasticity increase is inserted to extract also repeatedly and can not reduced flexible connecting pin even can provide again.
In addition, make connecting pin than enhancing productivity more than 5 times, can reduce cost with automatic lathe etc. with forging method.
The watchband of fourth embodiment of the invention is described to Figure 45 below in conjunction with Figure 40.This watchband is made of the boundary chain piece 101,102 and inboard connection chain piece 103a, the 103b in the outside.On each boundary chain piece, form with the 3rd embodiment in the same through hole 104 of connecting hole 36d and the blind hole connecting hole 105 same with the connecting hole 28 among first embodiment.
In a side connecting hole 103a, 103b, form connecting hole 106,107.
Extending to form the cross section at the central portion of the watchband length direction side of connection chain piece 103a along the width of watchband is semicircular raised line 108.Then forming the cross section that the raised line 108 for adjacent connection chain piece 103b engages rotationally in the side of an opposite side is semicircular recess 109.
Boundary chain piece 101,102 uses the connector 110 identical with first embodiment to be connected with connection chain piece 103a.In this occasion, the pipe of connector 110 111 and connecting hole 105 and 107 crimping, boundary chain piece 101 and 102 and connection chain piece 103a form one.
Then that the raised line 108 of adjacent connection chain piece 103b is chimeric with the recess 109 of connection chain piece 103a, and in the connecting hole 106 of the connecting hole 104 of boundary chain piece 101,102 and connection chain piece 103b, insert the connecting pin 112 same with the connecting pin 42 of the 3rd embodiment, and make the head 112b of connecting pin and the inwall crimping in hole 104, make axial region 112a and hole 106 chimeric with a gap.Like this, connection chain piece 103b just is connected with connection chain piece 103a rotationally.
Similarly connect each chain piece later on, form watchband.
Adjacent connection chain piece 103a, 103b are that semicircular raised line 108 rotates as shown in Figure 45 smoothly with engaging of recess 109 by the cross section.And, can prevent with the watchband longitudinal axis to be the chain piece distortion at center by engaging between the raised line that extends along the watchband width and recess, prevent that connecting pin from coming off.
When adopting the 4th embodiment, can prevent the distortion of chain piece, can not make it to come off so connect the inwall of pin-and-hole and connecting pin butt.In addition, owing to suppressed the distortion of chain piece, so can rotate smoothly between chain piece and the chain piece.Have again, because whole watchband is along the wrist smooth curved, so wear comfortable.And on the watchband that is provided with the boundary chain piece, recess and raised line are hidden in the boundary chain piece, can not diminish the aesthetic property of watchband.
The possibility of industrial utilization
