Abstract
The utility model relates to a kind of mfg. moulding die of aluminium alloy flexible pipe, and it comprises body, and body has relative first end and the second end, and first end has flexible pipe and draws structure, and flexible pipe draws structure and has the jut gone out from body surface projection.Jut comprises and is connected to the first wall on body and the second wall, and is connected to the end face between the first wall and the second wall, and wherein the junction of end face and the first wall and the second wall is arc.The second end is column type, and the radius of curvature of above-mentioned arc and the equal diameters of the second end.Equal by by the radius of curvature of arc and the diameter design of the second end, make flexible pipe draw structure when contact with aluminium alloy flexible pipe, reduce the stress intensity at arc place, the shutdown reducing the handing-over material place of aluminium alloy flexible pipe prints the probability ruptured.
Description
Technical field
The utility model relates to a kind of manufacture field of aluminium alloy flexible pipe, is more particularly a kind of mfg. moulding die of aluminium alloy flexible pipe.
Background technology
Aluminium alloy condenser pipe is mainly used in radiator and the air conditioning water tank pipe of automobile.At present, composition starts to use at condenser pipe close to 1050 series alloys flexible pipes, but at pulling process, very easily ruptures, have a strong impact on finished product length in the shutdown print at handing-over material place, and broken end is continuous draws at substantial man-hour; Only manage a lot of aluminium alloy producer and carry out various adjustment to composition within the scope of GB, drawing passage variable is changed to change again and still effectively can not be solved handing-over material breakage problem; Going the shutdown print solving aluminium alloy flexible pipe handing-over material to break so find a kind of effective method, is the fact that aluminium alloy condenser pipe manufacturing can not be evaded.
Utility model content
For deficiency of the prior art, the purpose of this utility model is to provide a kind of mfg. moulding die of aluminium alloy flexible pipe, to solve the problem of prior art.
The technical scheme that the utility model solves the problems of the technologies described above is, a mfg. moulding die for aluminium alloy flexible pipe, it comprises body, and body has relative first end and the second end, first end has flexible pipe and draws structure, and flexible pipe draws structure and has the jut gone out from body surface projection.Jut comprises and is vertically connected at the first wall on body and the second wall, and the first wall and the second wall are oppositely arranged; And the end face be connected between the first wall and the second wall, wherein the junction of end face and the first wall and the second wall is respectively arc.Further, the second end is column type, and the radius of curvature of above-mentioned arc and the equal diameters of the second end.
Preferably, the end of first end is column type, and the diameter of the end of first end is less than the diameter of the second end.
Preferably, the diameter of first end reduces gradually from jut toward the direction of the end of first end.
The beneficial effects of the utility model are; equal by by the radius of curvature of arc and the diameter design of the second end; when flexible pipe drawing structure can be made to contact with aluminium alloy flexible pipe; farthest reduce the stress intensity at arc place, reduce the probability of the shutdown print fracture at the handing-over material place of aluminium alloy flexible pipe.

Description of reference numerals:
The mfg. moulding die 10 of aluminium alloy flexible pipe, body 11, first end 12, flexible pipe draw structure 12a, the second end 13, jut 14, first wall 15, second wall 16, arc 15a, 16a, diameter R1, R2.
Detailed description of the invention
Below will with graphic exposure multiple embodiment of the present utility model, as clearly stated, the details in many practices will be explained in the following description.But should be appreciated that, the details in these practices is not applied to limit the utility model.That is, in some embodiments of the present utility model, the details in these practices is non-essential.In addition, for the purpose of simplicity of illustration, some known usual structures and assembly illustrate it by the mode simply illustrated in the drawings.
Fig. 1 is the schematic diagram of the mfg. moulding die of the aluminium alloy flexible pipe of the utility model one embodiment.As shown in the figure, the mfg. moulding die 10 of aluminium alloy flexible pipe of the present utility model comprises body 11, and body 11 has relative first end 12 and the second end 13.First end 12 has flexible pipe and draws structure 12a.Flexible pipe drawing structure 12a has the jut 14 from body 11 protrusion of surface.Jut 14 comprises the first wall 15 and the second wall 16 be vertically connected on body 11, and the first wall 15 and the second wall 16 are oppositely arranged.Jut 14 also comprises the end face 17 be connected between the first wall 15 and the second wall 16, and wherein the junction of end face 17 and the first wall 15 and the second wall 16 is respectively arc 15a, 16a.In addition, first end 12 is column type, and the radius of curvature of arc 15a, 16a is equal with the diameter R1 of the second end 13.
Because the junction of the first wall 15 and the second wall 16 is respectively arc 15a, 16a, therefore when the mfg. moulding die 10 of the aluminium alloy flexible pipe of present embodiment is when drawing aluminium alloy flexible pipe, the stress concentration degree that flexible pipe draws the position of structure 12a can be reduced.By reducing stress concentration degree, can avoid the mfg. moulding die 10 of aluminium alloy flexible pipe in the process drawn, cause the shutdown print breakage problem at the handing-over material place of aluminium alloy flexible pipe.
Furthermore; during practical application; by by the radius of curvature of arc 15a, 16a with the diameter R1 of the second end 13 design equal; when the work strip of mfg. moulding die 10 (being the position that flexible pipe draws structure 12a) can be made to contact with aluminium alloy flexible pipe; farthest reduce the stress intensity at arc 15a, 16a place, reduce the probability of the shutdown print fracture at the handing-over material place of aluminium alloy flexible pipe.
In addition, the end of the first end 12 of present embodiment is preferably column type, and the diameter R2 of first end 12 is less than the diameter R1 of the second end 13.So, circular shape dispersibles the stress distribution at the handing-over material place of aluminium alloy flexible pipe, avoids the shutdown print fracture joining material place.Preferably, the direction of the diameter R2 of first end 12 from jut 14 toward the end of the second end 13 reduces gradually.Present embodiment, by reducing and the design of circular arc type, avoids stress concentration at somewhere, and reduces the probability of the shutdown print fracture at handing-over material place.
Be described in detail the mfg. moulding die of aluminium alloy flexible pipe provided by the utility model above, the explanation of above embodiment just understands structure of the present utility model for helping; Meanwhile, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications.In sum, this description should not be construed as restriction of the present utility model.
