Preferably, the forming method of aforementioned long sleeve, wherein first groove of the step (D) have one by this first
Hold extend towards second extreme direction and section be polygon first segment and one by the first segment towards second extreme direction
Extend and section is circular second segment.
Preferably, the forming method of aforementioned long sleeve, wherein the step (D) is first to mold the first segment reshaping to go out to be somebody's turn to do
Second segment.
Preferably, the forming method of aforementioned long sleeve, wherein the section of second groove of the step (F) is polygon.
Preferably, the forming method of aforementioned long sleeve, wherein the forming method of the long sleeve also includes one and is connected in this
Step (G) after step (F), the step (G) remove the partition wall to be connected to first groove and second groove.
The beneficial effects of the present invention are: the long sleeve that sequentially raw material can be made to be molded via above-mentioned steps is not necessarily to
By cutting processing procedure, equipment and cost of material can be effectively reduced, reduce process time and improve production efficiency, moreover it is possible to be promoted whole strong
Degree.

Specific embodiment
The following describes the present invention in detail with reference to the accompanying drawings and embodiments.
Referring to Fig.2, the embodiment of the forming method of long sleeve of the present invention sequentially comprises the steps of firstly, step 21 is
Prepare the column raw material 3 of a predetermined size, which has opposite a first end 31 and a second end 32.In the present embodiment
In, which is cylindric.
Then, step 22 is to mold one first chamfering 311 in the first end 31 of the raw material 3.Next, step 23 be by
After the first end 31 of the raw material 3 of step 22 and 32 turned upside down of second end, the first end 31 then at the raw material 3 is molded
One first pit 312, while one second chamfering 321 is formed in the second end of the raw material 3 32.
Refering to Fig. 2,3,4, step 24 be mold a second dimple 322 in the second end 32 of the raw material 3, and along this first
Pit 312 squeezes the first end 31 of the raw material 3, and mold one extended by the first end 31 towards 32 direction of second end the
One groove 313.First groove 313 has one to be extended by the first end 31 towards 32 direction of second end and section is polygon
First segment 314 and one by the first segment 314 towards 32 direction of second end extend and section be circular second segment 315.In
In the present embodiment, which is first to mold 314 reshaping of first segment to go out the second segment 315, the section of the first segment 314
For hexagon.
Herein it should be particularly noted that, since step 24 is the first end along 312 reverse extrusion of the first pit raw material 3
31, therefore, the length of raw material 3 can be greater than 3 length of raw material of previous step 23 in step 24.
Then, step 25 is will first to forge again after the first end 31 of the raw material 3 of the step 24 is inverted with second end 32
The raw material 3 is broken, the raw material 3 is made to have 33, one, a head extended by the second end 32 towards 31 direction of first end by this
Bar portion 34 that first end 31 extends towards 33 direction of head and one are integrally connected with the necking part on the head 33 and the bar portion 34
35, the section of the necking part 35 is tapered towards 34 direction of bar portion by the head 33, and the outer diameter of the bar portion 34 is less than this
The outer diameter on head 33.
Refering to Fig. 2,5, step 26 is the second end 32 of the raw material 3 to be squeezed along the second dimple 322, and mold one by this
Second end 32 extends towards 34 direction of bar portion and section is the second groove 323 and one of polygon between second groove 323
With the partition wall 36 between first groove 313.In this present embodiment, the section of second groove 323 is quadrangle.
Herein it should be particularly noted that, since step 26 is the second end along 322 reverse extrusion of the second dimple raw material 3
32, therefore, the length of raw material 3 can be greater than the length of raw material 3 in step 25 in step 26.
Finally, step 27 is to thrust the partition wall 36 to be connected to first groove 313 and second groove 323, and be made
One long sleeve 4.
Herein it should be particularly noted that, above-mentioned steps 21 are to step 27 to be carried out using corresponding mold, and mold
The existing knowledge for being designed as those skilled in the art, herein not add to repeat.
