The specific embodiment
For the technical solution of the utility model is described better, provided preferred embodiment of the present utility model below.Yet be understandable that, following embodiment is only the preferred technical scheme of the utility model, can not be interpreted as restriction of the present utility model.
As shown in Figure 1, a kind of telescopic antenna copper pipe disclosed in the utility model enlarging and necking processing device comprise: expansion-contraction pipe machine 1, flaring die 2, reducing die 3, mandrel 4, upper clamp formwork 5 and lower clamp formwork 6.
Described expansion-contraction pipe machine is for applying enlarging and necking force to processed telescopic antenna copper pipe; Expansion-contraction pipe machine is the existing technology in this area, adopts existing expansion-contraction pipe machine.
As shown in Figure 3, described flaring die 3, is installed on described expansion-contraction pipe machine, the enlarging size while controlling described processed telescopic antenna sleeve pipe enlarging when flared end is carried out to enlarging.After described antenna tube need to being extended to corresponding size, need corresponding with it enlarging film.Described pipeline dragged the restriction of flaring die to carry out controller size and dimension.
As shown in Figure 2, described reducing die 2, is installed on described expansion-contraction pipe machine, the reducing size when controlling described processed telescopic antenna copper pipe reducing when necking end is carried out to reducing; After described antenna tube need to being contracted to corresponding size, need corresponding with it reducing die.Described pipeline dragged the restriction of flaring die to carry out controller size and dimension.
Mandrel 4, is installed on described expansion-contraction pipe machine, for from telescopic antenna copper pipe described in inner support; To facilitate the processing of described enlarging and reducing.
Described upper clamp formwork 5 and described lower clamp formwork 6 as shown in Figure 4,5, for providing chucking power from above-below direction for described processed telescopic antenna respectively.Preferably, upper and lower clamping comprises clamp body 7 and fixture core 8, the plastic-steel material manufacture of fixture core, and fixture core end face exceeds clamp body end face 0.2mm, and fixture core center has circular arc, and the apex height difference in height high and fixture wicking surface of center circular arc is 0.05mm.Among one of described upper and lower clamping, be provided with guide finger 9, the another one of described upper lower clamp formwork is provided with pilot hole 10, and described guide finger and pilot hole are to being applied to guide the concrete movement position of upper lower clamp formwork.
Further, when the wall thickness of telescopic antenna sleeve pipe is 0.2mm, according to the requirement of YS/T267-1994 standard, the error range of the machining accuracy of its enlarging and reducing is at 0.06mm.And find according to a large amount of further investigations of the present utility model, while only having the error of wall thickness to be controlled at 0.05mm within the scope of, guarantee antenna is bearing while transshipping still in extended state.
As shown in Figure 6,7, based on above-mentioned discovery, device of the present utility model creatively also comprises refine reducing die 13, refine flaring die 12, and described refine reducing die, for the external diameter of meticulous finishing pipe, makes its machining tolerance scope within 0.02mm; Described refine flaring die is for the internal diameter of refine pipe, makes within its machining tolerance is controlled at 0.02mm.The structure similar of the refine reducing in Fig. 6,7, flaring die and aforesaid reducing flaring die, but its size is more accurate, thus guaranteed the quality of processing.
The utility model is stated in the use device and is carried out antenna processing step while manufacturing: the second section antenna tube (accompanying drawing 2-2) of take be example: fill flaring die-load onto, lower clamp formwork-flaring die and upper and lower clamping to center-dress part and mandrel-enlarging-dress refine reducing die-refine external diameter-dress reducing die-reducing-dress refine flaring die-refine internal diameter.
First adopt above-mentioned processing step to carry out the mode that preliminary reducing, enlarging and refine enlarging, reducing combine can guarantee adding and just can form comparatively approaching size man-hour for the first time, then carry out meticulous repairing and so progressively approach the difficulty that first desirable size has reduced processing, because one-shot forming can reach the precision needing, for machine for shrinking, be difficult to accomplish, through secondary, meticulous correction can guarantee the precision of processing simultaneously, thereby has accomplished well to take into account on difficulty of processing He in precision.Above-mentioned advantage is all further provided with refine reducing die and refine flaring die and brings in the utility model.
Closer, because domestic common machine for shrinking precision is not high, easily cause the problems such as part ftractures, and unstability is wrinkling, difficulty is shaped.In this practicality row embodiment, for driving the drive unit of flaring die and reducing die to be equipped with linear guides 11 and control valve, improve machine tool motion precision and stationarity, the size of power while controlling expansion, reducing.Cross the travel speed that described flow speed control valve regulates existing guide rail slide plate expand to control, the size of power during reducing
The beneficial effects of the utility model: the unique design the utility model proposes, there is following advantage and disadvantage: 1, clamping deformation is little, after copper pipe is end formed, substantially unchanged before measuring the cylindricity of copper pipe and processing.2, copper pipe is end formed easily, part high conformity, and efficiency is high, and qualification rate reaches more than 99%.3, the antenna of processing is through field trial in this way, and reliability is high.
