Abstract
The utility model provides a multi sphere section stirring head for under high temperature, it includes centre gripping handle (1), the shaft shoulder (2) and shank -pin (3), characterized by the shaft shoulder (2) be multi sphere section curve solid of revolution structure, centre gripping handle (1) and shank -pin (3) links to each other with the both ends of the multi sphere section curve solid of revolution are whole respectively. The utility model discloses a shank -pin can not only save a large amount of raw and other materials, has good heat dissipation moreover, inhales that to shake efficiency good, can bear high temperature welded advantage.
Description
Technical field
The utility model relates to a kind of agitating friction solder technology, especially a kind of stirring-head of perfect heat-dissipating, specifically a kind of for the multi sphere section stirring-head under high temperature.
Background technology
As everyone knows, stirring-head is the key tool of agitating friction welding, whether its structural design is reasonable, be directly connected to the service life of stirring-head, and existing stirring-head is made up of cylindrical clamping part, back taper shaft shoulder portion and pin portion mostly, its absorbing, stability affect very greatly by welding material, and especially high temperature resistance is poor, therefore design a kind of energy and realize cooling fast, saving material, absorbing, stablize good etc. mixing needle being the key improving friction stir welding.
Utility model content
The purpose of this utility model is single for the stirring-head structure of existing agitating friction, and poor-performing, is difficult to the problem meeting applied at elevated temperature, designs a kind of for the multi sphere section stirring-head under high temperature.
The technical solution of the utility model is:
For the multi sphere section stirring-head under high temperature, it comprises grip shank 1, the shaft shoulder 2 and mixing needle 3, it is characterized in that the described shaft shoulder 2 is multi sphere section curve revolving body structure, and grip shank 1 and mixing needle 3 are connected with the two ends entirety of multi sphere section curve revolving body respectively.
Described multi sphere section curve is serpentine.
The described shaft shoulder 2 is made up of three sections of arc curve revolving bodies, a concave inward structure 4 being conducive to reducing material usage and be convenient to the inside contraction of dispelling the heat is formed between the second segment arc curve revolving body of the first paragraph arc curve revolving body be wherein connected with grip shank 1 and next-door neighbour, the 3rd section of structure that arc curve revolving body is big up and small down be close to second segment arc curve revolving body, the progressively step surface that matches of transition formation and mixing needle 3.
The beneficial effects of the utility model:
Mixing needle of the present utility model can not only save a large amount of raw material, and has that thermal diffusivity is good, absorbing efficiency is good, can bear the advantage of high-temperature soldering.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 1.
For the multi sphere section stirring-head under high temperature, it comprises grip shank 1, the shaft shoulder 2 and mixing needle 3, it is characterized in that the described shaft shoulder 2 is multi sphere section curve revolving body structure, and grip shank 1 and mixing needle 3 are connected with the two ends entirety of multi sphere section curve revolving body respectively.The multi sphere section shaft shoulder 2 is conducive to the heat radiation of stirring-head and saves material, and simultaneously by ascending more from big to small for shoulder design, finally descending serpentine, stirring-head is good stability in rotary course.And the serpentine shaft shoulder can also realize whirlwind, accelerate the heat radiation of stirring-head.As shown in Figure 1, the shaft shoulder 2 is made up of three sections of arc curve revolving bodies, a concave inward structure 4 being conducive to reducing material usage and be convenient to the inside contraction of dispelling the heat is formed between the second segment arc curve revolving body of the first paragraph arc curve revolving body be wherein connected with grip shank 1 and next-door neighbour, the 3rd section of structure that arc curve revolving body is big up and small down be close to second segment arc curve revolving body, the progressively step surface that matches of transition formation and mixing needle 3.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art and is realized.
