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 to 6, a kind of gradual drawing-die umbrella handle copper pipe 3 group 1, sheet group 1 is rectangular sheet, sheet group 1 is integrally connected to form at length direction head and the tail by continuous print some copper sheets 2, the width of copper sheet 2 junction is provided with recessed cutting groove 4, and being provided with of cutting groove 4 is beneficial to copper sheet 2 and is wound into separation cuts to adjacent two copper pipes 3 after copper pipe 3; Two long limits of copper sheet 2 are the edge structure sword limit 7 that thickness diminishes gradually, sword limit 7 is after copper sheet 2 is wound into copper pipe 3, two sword limits 7 can superpose staggered being close together, the change of thickness is designed with and is beneficial to the level and smooth of the wall thickness that interlocks, thickness transitions is mild, when copper sheet 2 is bent into copper pipe 3, being crisscross arranged of sword limit about 7 overlying contact of both sides; The surface of copper sheet 2 one side is provided with some chamfered grooves 5, and chamfered groove 5 axis is parallel with copper sheet 2 length direction, and some chamfered grooves 5 are equally spaced arranged in parallel, after copper sheet 2 is wound into copper pipe 3, be positioned at copper pipe 3 inwall with chamfered groove 5 one side, chamfered groove 5 is conducive to the deformation of Forging Process, is conducive to the shaping of copper pipe 3.It can be bent into cross section with the circular copper pipe 3 inwardly concaving structure at width by drawing-die constraint, drawing-die is a kind of mould that can retrain bending copper sheet 2 width angle, the bending that copper sheet 2 can comply with drawing-die relates to, make it to produce recessed structure, namely on copper pipe 3, bending goes out the arcuate structure that recessed cross section is the inner side of circular copper pipe 3, and this arcuate structure becomes guide groove 8.Guide groove 8 is conducive to the guiding in umbrella handle telescopic process, and avoids rotation circumferential between the ectonexine of umbrella handle.
Cutting groove 4 and chamfered groove 5 are in the tow sides of copper sheet 2.Like this after copper sheet 2 is wound into copper pipe 3, chamfered groove 5 is positioned at copper pipe 3 inwall, cutting groove 4 is positioned at the outer axial surface of copper pipe 3, can be conducive to the cutting and separating between adjacent two copper pipes 3 at the cutting groove 4 in outside, adjacent two copper pipes 3 are copper pipe 3 and reel and be separated with the copper sheet 2 of cutting groove 4 between the first two.
Chamfered groove 5 for the cross section being absorbed in copper sheet 2 lower face be the groove of triangular structure.After copper sheet 2 is bent into copper pipe 3, chamfered groove 5 is positioned at copper pipe 3 inwall side, chamfered groove 5 axis and copper pipe 3 axis being parallel, and the chamfered groove 5 cross section shape in copper pipe 3 becomes linear, and cutting groove 4 is around copper pipe 3 circle outer Monday.Leg-of-mutton chamfered groove 5 after copper sheet 2 is wound generation deformation, or closes into a line, and the space of chamfered groove 5 inside originally reduces just, simultaneously with providing deformation space for the deformation of copper sheet 2.
Copper sheet 2 is provided with the through hole 6 in impenetrating thickness direction.Through hole 6 is first carried out before copper sheet 2 is wound into copper pipe 3, which decreases the difficulty of perforate, once after copper sheet 2 is wound into copper pipe 3, the perforate work of through hole 6 is just not easy to carry out.
Chamfered groove 5 is arranged in the middle part of copper sheet 2 width, near sword limit 7, be not provided with chamfered groove 5.Because do not need large bending deformation near the guide groove 8 of copper pipe 3, therefore chamfered groove 5 arrangement of copper sheet 2 is avoided making chamfered groove 5 herein, saves labour cost.
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.
