Pit, while it is molded second chamfering at the second end of the raw material.
It is preferred that the forming method of foregoing long sleeve, the wherein step (E) are will to pass through the step
Suddenly the first end of the raw material of (D) forges the raw material again after being inverted with the second end.
It is preferred that first groove of the forming method of foregoing long sleeve, the wherein step (D)
Section be polygon.
It is preferred that first groove of the forming method of foregoing long sleeve, the wherein step (D)
Extended with one by the first end towards second extreme direction and section is the first of polygon
Section, and one extended and section is circular second by the first paragraph towards second extreme direction
Section.
It is preferred that the forming method of foregoing long sleeve, wherein the step (D) is first to mold this
First paragraph reshaping goes out the second segment.
It is preferred that second groove of the forming method of foregoing long sleeve, the wherein step (F)
Section be polygon.
It is preferred that the forming method of the forming method of foregoing long sleeve, the wherein long sleeve also wraps
Containing a step (G) being connected in after the step (F), the step (G) removes the partition wall with even
Lead to first groove and second groove.
The beneficial effects of the present invention are：Sequentially can be molded the raw material via above-mentioned steps
Long sleeve, need not move through cutting processing procedure, can effectively reduce equipment and cost of material, reduce plus
Production efficiency is improved between man-hour, moreover it is possible to lift bulk strength.

Embodiment
Below in conjunction with the accompanying drawings and embodiment the present invention is described in detail.
Refering to Fig. 2, the embodiment of the forming method of long sleeve of the present invention sequentially comprises the steps of：
First, step 21 is to prepare the column raw material 3 of a preliminary dimension, and the raw material 3 has opposite
One first end 31 and one second end 32.In the present embodiment, the raw material 3 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 is by the end of first end 31 and second of the raw material 3 Jing Guo step 22
After 32 turned upside downs, one first pit 312 is molded then at the first end 31 of the raw material 3,
Simultaneously one second chamfering 321 is molded at the second end 32 of the raw material 3.
Refering to Fig. 2,3,4, step 24 is that one is molded at the second end 32 of the raw material 3
Two pits 322, and along the first end 31 of the first pit 312 extruding raw material 3, and be molded
Go out first groove 313 extended by the first end 31 towards the direction of the second end 32.This
One groove 313 has one to be extended by the first end 31 towards the direction of the second end 32 and section is
The first paragraph 314 of polygon, and one by the first paragraph 314 towards the direction of the second end 32 extend
And section is circular second segment 315.In the present embodiment, the step 24 is first to mold this
The reshaping of first paragraph 314 goes out the second segment 315, and the section of the first paragraph 314 is hexagon.
To be illustrated herein, because step 24 is reversely squeezed along first pit 312
The first end 31 of the raw material 3 is pressed, therefore, the length of raw material 3 can be more than previous in step 24
The length of raw material 3 of step 23.
Then, step 25 be first by the first end 31 of the raw material 3 Jing Guo the step 24 with
Second end 32 forges the raw material 3 again after being inverted, and the raw material 3 is had one by second end 32
Towards 33, one, the head of the direction of first end 31 extension by the first end 31 towards the head
The bar portion 34 of 33 directions extension, and a contracting for being integrally connected with the head 33 and the bar portion 34
Neck 35, the section of the necking part 35 be it is tapered towards the direction of bar portion 34 by the head 33,
And the external diameter of the bar portion 34 is less than the external diameter on the head 33.
Refering to Fig. 2,5, step 26 is second that the raw material 3 is extruded along second pit 322
End 32, and mold one by second end 32 towards the direction of bar portion 34 extension and section be more
Second groove 323 of side shape, and one between second groove 323 and first groove 313
Partition wall 36.In the present embodiment, the section of second groove 323 is quadrangle.
To be illustrated herein, because step 26 is reversely squeezed along second pit 322
The second end 32 of the raw material 3 is pressed, therefore, the length of raw material 3 can be more than step in step 26
The length of raw material 3 in 25.
Finally, step 27 be thrust the partition wall 36 with connect first groove 313 with this
Two grooves 323, and a long sleeve 4 is made.
To be illustrated herein, above-mentioned steps 21 to step 27 are all using corresponding
Mould is carried out, and the existing knowledge for being designed as those skilled in the art of mould, is refused herein more
Add and repeat.
