Specific embodiment
The following describes the present invention in detail with reference to the accompanying drawings and embodiments:
Refering to Fig. 2,3, an embodiment of the manufacturing method of short sleeve of the present invention is comprised the steps of
Steady step 11: preparing a raw material 2, which has opposite a first end 21 and a second end 22.It will be first
Row explanation, the size of the raw material 2, be it is corresponding used in mold kenel, and the specification of short sleeve made of being intended to and it is pre-
It is standby.And the selection of the size of the detail characteristic and raw material 2 of the mold in relation to using, belonging to those skilled in the art can be according to
According to the technology contents that demand is completed, and not reach the main feature of this case problem to be solved, therefore no longer adds to repeat in this.
One pre-profiling step 12: one first chamfering 211 is molded in the first end 21 of the raw material 2.
One continuous forming step 13: the first end 21 of the raw material 2 is inverted with the second end 22, then in the raw material 2
First end 21 molds one first pit 212, and forms one second chamfering 221 in the second end 22 of the raw material 2 simultaneously.It is special
Illustrate, in the present embodiment by the inverted movement of raw material 2, is the design of mating mold and carries out, in present embodiment
The subsequent inversion movement referred to is also same, no longer additional description.
One forges expanding step 14: the first end 21 of the raw material 2 being inverted with the second end 22, then forges and squeezes this
Raw material 2 molds a second dimple 222 in the second end 22 of the raw material 2, and make the raw material 2 have length by this second
End 22 extend towards 21 direction of first end and 23, one, the head of width radial expansion by the first end 21 towards the head 23
The bar portion 24 and a necking part 25 being integrally connected between the head 23 and the bar portion 24 that direction extends.At this point, due to the original
Material 2 is all integrally solid rather than hollow state, therefore in the raw material 2 integrally by powerful when forging power, in addition to preboarding
Outside part at the head 23, the predetermined part for forming the bar portion 24, which is also enough to support, described forges power.Furthermore when the head
Portion 23 forges at this and tentatively forges molding in expanding step 14, and subsequent extruding movement mainly makes the head 23 and the bar
The size or ratio in portion 24 meet demand, and are uniformly to apply to the raw material 2 outer compared to range bigger for forging
Power, in the case where the 2 still not formed large-scale hollow space of raw material, which forges in expanding step 14 also not at this
The phenomenon that being easy to happen skew or fracture.In addition, the section of the necking part 25 be by the head 23 towards 24 direction of bar portion gradually
Contracting, and is being formed with a lead angle 251 with 24 junction of bar portion, enable the head 23 via the necking part 25 bar portion 24 that arrives
The extension that curve is presented, optimizes whole structural strength whereby.
One punching step 15: it along 222 punching press of the second dimple raw material 2, molds one and extends to this from the second end 22
The preparation blind hole 200 of bar portion 24 and a block in the preparation blind hole 200 one end and adjacent to the thin-walled of the first end 21 209.
In the present embodiment, the thin-walled 209 with a thickness of 3 millimeters, but size for molding must be cooperated to adjust when actual implementation, and
It is not limited.
One perforation step 16: as shown by the arrows in Figure 2, punching press is carried out from the thin-walled 209 toward the second end 22, is formed consistent
Through-hole 201.
One pressing steps 17: being the mold (not being painted in figure) of quadrangle from the second end 22 toward the first end using a section
21 carry out punching press, mold second groove 223 extended by the second end 22 towards the first end 21.As shown in figure 4, this second
The section of groove 223 is in quadrangle.It then using a section is again the mold (not being painted in figure) of hexagon from the first end 21
Punching press is carried out toward the second end 22, molds first groove 213 extended by the first end 21 towards the second end 22.Such as Fig. 5
Shown, the section of first groove 213 is hexagonal.After completing the pressing steps 17, that is, it can be made into a short sleeve finished product
3。
Again refering to Fig. 2 and Fig. 3, in the past when forming inner hole, it is necessary to first be molded respectively by the opposite end of the raw material 2
The circular hole of initial kenel, it is subsequent also need respectively to be carried out by opposite end again to be extruded from type go out predetermined shape.But the present embodiment
It is that the program of the preparation blind hole 200 of prepared subsequent extrusion groove is disposably directly reached, at this with the punching step 15
Pressing steps 17 can respectively shape first groove that section is hexagon respectively from the first end 21 and the second end 22
213 and section be quadrangle second groove 223.In addition to this, it more can be formed directly in the perforation step 16 predetermined
Section in the necking part 24 is the circular through hole 201.Therefore, the present embodiment is compared to previous manufacturing method,
Really it can reach the purpose of simplified step.
And the bar portion 54 of made short sleeve finished product 3 and the lenth ratio range on the head 53 are 1~1.2, with symbol
Close the specification used that circulates now.
