Detailed description of the invention
Be described in further detail the utility model in conjunction with the accompanying drawings and embodiments now, these accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in figures 1-8, a kind of umbrella handle copper pipe 7 drawing-die 1 with guide groove 8, have in certain thickness drawing-die 1 and be placed with several nibs 2, the thickness direction of drawing-die 1 that what nib 2 was vertical run through, nib 2 madial wall is provided with a projection 3, protruding 3 become large from nib 2 one end gradually to other end size, the nib 2 mouthfuls of protruding 3 minimum one end of size is entrance 4, the nib 2 mouthfuls of protruding 3 maximum one end of size is outlet 5, copper pipe 7 can peripheral shape coupling penetrate nib 2 from entrance 4, and copper pipe 7 can peripheral shape coupling pass nib 2 from outlet 5.Size becomes large projection 3 gradually can ensure that copper pipe 7 is gradual by the deformation produced during nib 2, can not produce comparatively macrolesion because of copper pipe 7 at deformation process.
Drawing-die 1 is disc, and what nib 2 ran through is distributed in disc drawing-die 1.On the securing means, the nib 2 that the copper pipe 7 that many copper pipes 7 can be synchronous is different, working (machining) efficiency is very high in the setting that discoidal drawing-die 1 can be fixed.
The shape of cross section of entrance 4 is circular, and the shape of cross section of outlet 5 is the circle with the arcuate structure inwardly concaved, and nib 2 shape of cross section from entrance 4 to outlet 5 is become large circle gradually with recessed arcuate structure size.The shape of cross section of entrance 4 makes copper pipe 7 can be easy to enter into nib 2, and projection 3 size of gradual change can make copper pipe 7 be positioned at the inner optional position of nib 2 can both ensure that copper pipe 7 shape of cross section herein agrees with nib 2 inner wall shape herein to greatest extent.
Penetrate nib 2 from entrance 4 and pass the copper pipe 7 of nib 2 from outlet 5, its shape of cross section coincide with nib 2 shape of cross section at place place all the time in nib 2.The structure of protruding 3 is coincide in the structure of outlet 5 place and copper pipe 7 finished product guide groove 8.
Nib 2 and protruding 3 inner surfaces thereof are provided with some the stripeds 6 protruded at nib 2 inner surface of evenly arrangement, and striped 6 is consistent with nib 2 Axis Extension direction.Striped 6 shape of cross section is circular arc or triangle.When striped 6 structure can make copper pipe 7 inner by nib 2, copper pipe 7 outer wall can be ground by striped 6 striped 6 marked along copper pipe 7 Axis Extension direction, the adhesion area that such striped 6 is conducive to stiction when copper pipe 7 is fixed on umbrella handle inside pipe wall or is sticked together.
Line between the shape of cross section of protruding 3 and the shape of cross section of nib 2 is the smooth line of arc.Be that the larger place of bending angle occurs, it needs smooth arc excessive, is unlikely to copper pipe 7 in Forging Process like this and is subject to macrolesion at bending part herein.
Guide groove 8 is conducive to the guiding in umbrella handle telescopic process, and avoids rotation circumferential between the ectonexine of umbrella handle.
The utility model in use, entrance 4 place of each nib 2 of insertion that copper pipe 7 free end of many circular cross sections is corresponding, then apply tractive force copper pipe 7 is pulled out from outlet 5 one end, because the structure of protruding 3 and striped 6 can be had an effect with copper pipe 7, now just there is deformation in copper pipe 7 accordingly.Copper pipe 7 of the present utility model can be that theory unlimited is long, also can the copper pipe 7 of a joint finite length above, the copper pipe 7 of finite length can be after a copper pipe 7 promote reach, finally leave nib 2, and end feeding copper pipe 7 successively.
Above according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, related personnel in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine technical scope according to right.
