As shown in Fig. 1~Figure 16, the invention is realized in this way, provide a kind of manufacturer of hollow long bolt bolt
Method, comprising the following steps:
Step S1 manufactures head 1 and hollow long bolt 2 respectively；
Head 1 is connect to form hollow long bolt bolt by step S2 by friction welding with hollow long bolt 2.
Then the embodiment of the present invention passes through friction welding by being first manufactured on head 1 and hollow long bolt 2 respectively
Mode makes head 1 connect to form hollow long bolt bolt with hollow long bolt 2, without using highly energy-consuming and the multitask of high price
Position forming machine makes hollow long bolt bolt, and overall process do not need addition lubricant and filler metal, can it is effectively save at
This；In addition, it is original in such a way that molding machine types it out again secondary deep hole machining using friction welding substitution, it can effectively improve
Productivity and yields；Processing charges is low, power saving, being capable of effectively save cost；Weldment is not necessarily to special cleaning, Yi Shixian mechanization
And automation, it is simple and convenient.
Embodiment two
The step " manufacturing head 1 and hollow long bolt 2 respectively " specifically includes:
The head is manufactured by cold-heading molding；
Select hollow long bolt described in tubular object extruding.
In the present embodiment, by the way that head 1 and hollow long bolt 2 to be separately formed, the two can be welded convenient for subsequent
It connects, in addition, the two is separately formed, can effectively simplify process, it is simple and convenient.
Specifically, the hollow long bolt is the tubing that preset length is required by measuring, then by the hair at tubing both ends
Thorn removes, then tapping etc. is fabricated on the excircle of tubing.Tubing generally selects steel pipe.Hollow long spiral shell described herein
Bar refers to the length of the screw rod long bolt more much larger than the outer diameter of screw rod and internal orifice dimension, this long bolt using common cold-heading at
Type technique is difficult to make qualified finished product, and thin deep hole machining difficulty is big, is also easy to tool for breaking off, and the sky in the application citing is long
Spiro rod length is greater than 160mm, and the outer diameter of screw rod is less than 10mm, and internal orifice dimension is less than 6mm, and however, it is not limited to this, in citing in
The size of empty long bolt and the protection scope of the application are unrelated.
Embodiment three

Include:
Step S21 generates head and hollow long bolt 2 by parameter preset, high speed rotation stirring tool and weldment
Squeeze forging and friction-stir；
Step S22, head 1 and hollow long bolt 2 generate welding fabrication after violent Plastic Flow.
In the present embodiment, by high speed rotation stirring tool and weldment, without using highly energy-consuming and the Multi-task position of high price
Forming machine makes hollow long bolt bolt, and overall process does not need addition lubricant and filler metal, being capable of effectively save cost.
Example IV
The parameter preset includes speed of agitator, stirring input power, stirs and squeeze into rate, stirring residence time and stirring
Direction.By the setting and debugging to different parameter presets, it can effectively optimize the friction welding (FW) between head and hollow long bolt 2
Connect efficiency and welding quality.
Embodiment five
The range of the speed of agitator is between 900RPM~2700RPM.The range of the stirring input power 0~
Between 25KJ.The range for squeezing into rate is between 0.5mm/s~2mm/s.The stirring residence time is between 1s~9s；

3s, 4.5s or 9s.
3~Figure 13 of comparison diagram is consequently increased by the quantity of material of transport flow when the residence time increases, and then makes stirring area
Expand growth；Improving revolving speed facilitates material by thermal softening, reduces flow impedance, and then forms stirring area, and due to increasing
Add the material of unit time to convey behavior, thus effectively helps material flowing.However, excessive speeds be easy to cause the strength of materials terraced
Degree decline, and the relative motion state of stirring tool and storeroom changes, thus weaken the ability of screw thread geometry conveying material；
Change stirring tool direction of rotation to impact material sucking point and point of release, thus it is turned to material flowing and weldment shape
Looks influence very huge.
The great influence of destruction bond strength of friction welding process parameter butt-welding fitting, wherein the revolving speed of stirring tool is imitated
It should be the most obvious.
When 900rpm, the discovery of weldment pattern is looked into sight, and weldment interface generates complete engagement, with torque wrench and tensile test
After machine experiment, its bond strength highest is found.However, the bond strength of weldment can not substantially be influenced by squeezing into rate variation.And it stirs
The increase for mixing the residence time improves heat input, and then makes the complete speed of joint interface, improves bond strength.
