Description
Technical field
The invention belongs to little manufacturing field, more specifically, relate to manufacturing installation and the method for a kind of little footpath silk or pipe.
Background technology
In recent years, because the fast development in fields such as Aero-Space, national defense and military, manufacturing has more and more higher requirement to Precision Machining, in addition, because successful Application and the popularization of microrobot, miniature performance element in the medical domain have big demand for micro-diameter pipe, microelectrode more microminiaturized, low-cost, that high yield quantizes.
Little footpath silk or pipe refer to have the micron order diameter, the silk of slenderness ratio high (greater than 10) or pipe, because little footpath silk or pipe are equipped with special performances, as electrophoresis, be similar to performances such as human body capillary mechanism and high ductibility, miniature property, thereby have a wide range of applications in fields such as information, the energy, medical treatment, national defence.For example, in medical science, minisize capillary pipe inserted carry out in the animal body in the body in real time, analyze continuously, directly obtain chemical action message in the body, in life science, obtained important use.
Little footpath silk also can be used as microelectrode and uses, and microelectrode generally includes two kinds of connotations: (1) refers to the diameter dimension microminiaturization of electrode, as microminiaturized ISE.(2) refer to that in electrochemical analysis electrode area is very little but entire electrode is not a microminiaturized class electrode, as the indicator electrode used in polarography and the voltammetry etc.Because the electrode surface of microelectrode is very little, its electrochemical properties has the unexistent distinct advantages of many conventional electrodes, for example the starting the arc electrode of using as spark machined in the Precision Machining.
At present, little footpath silk of glass fiber material or pipe generally are to utilize alcohol blast burner to elongate under the effect of mould to conduit heating back, little footpath silk of metal material or pipe generally are to use multistage mould to carry out descending drawing or compression moulding, preceding kind method is difficult to internal diameter and the wall thickness control of little footpath silk or pipe, generally all be to judge with subjective sensation, product parameters is difficult to standardization, and efficient is very low; Though then the prepared product parameters of a kind of method is more accurate, the preparation expense of mould is too high, and requires metal material to possess good ductility and tensility, otherwise " fracture of wire " can occur.These two kinds of methods are commonly used to prepare diameter silk and pipe big (more than the millimeter level), that specification is more single, and are then helpless for meticulousr little footpath silk and pipe (about ten microns of diameters).
Chinese patent literature 201210010675.5 discloses a kind of apparatus and method that prepare the array pattern based on the static spray printing, it utilizes the principle of electrostatic spinning spray printing to carry out the pattern preparation, but this scheme only is used for the preparation of pattern, be not suitable for the preparation of micron-sized silk or pipe, and the jet that this scheme sprays nozzle only is to rely on flow pump to control, can't accurately control flow velocity and the flow of spray printing jet, make the pattern of preparation evenly to distribute, influence the electric property of device.Particularly, owing to can't accurately regulate and control jet, make and to regulate the occasion of the multiple not isostructure spinning structure of can't satisfying the demand to the spinning inner wall structure that jet forms.
