Embodiment Construction
[0030] Combine below Figure 1 to Figure 8 , to further describe in detail the specific implementation of the present invention - "a method for processing a metal nozzle".
[0031] (1) Take a stainless steel plate 1, and process a cylindrical boss array 2 on the plate, such as figure 2 shown.
[0032] Preferably, the stainless steel plate 1 used in this case is made of sus304, has a diameter of 30mm, and a thickness of 1mm.
[0033] Preferably, in this case, the cylindrical boss array 2 is processed on the flat plate 1 by a CNC milling machine.
[0034] Preferably, the number of cylindrical bosses contained in the cylindrical boss array 2 can be designed according to actual needs, and can be arranged in a linear or circular matrix, and the size of the bosses can be determined according to actual requirements. In this case, six cylindrical bosses 3 uniformly distributed along the circumference are selected, and each cylindrical boss 3 has a diameter of 0.5 mm and a height o...

The invention discloses a machining method for a metal spraying nozzle. A high-performance metal spraying nozzle structure is machined through an electroforming process by utilizing the characteristicthat stainless steel is not easily dissolved by electrochemistry and taking a stainless steel plate which contains micro-through hole arrays as a base. The machining method comprises the following steps: first, providing a flat stainless steel plate, forming cylindrical boss structures of an array on the flat plate, and forming a through hole in the centre of each cylindrical boss structure; then, performing an electroforming process on the flat plate to form a metal layer with open holes; peeling the metal layer to form a group spraying nozzle blank plate; and performing thinning and cuttingtreatment on the group spraying nozzle blank plate to obtain a plurality of metal spraying nozzles with certain thickness and aperture. According to the machining method for the metal spraying nozzle, the cost can be greatly reduced; the process can be simplified; small-aperture horn-shaped metal spraying nozzles of which hole walls are in smooth transition are produced at high efficiency in batches; and the machining method for the metal spraying nozzle is more suitable for practical production.
Description
technical field [0001] The invention belongs to the field of micro special processing, in particular to a processing method of a metal nozzle. Background technique [0002] At present, metal mesh parts are widely used in precision instruments, aerospace, medical equipment, pharmaceuticals, chemical fibers and other fields. In terms of pharmaceuticals and medical equipment, metal nozzles play an extremely important role in these aspects. So far, the manufacturing methods of micro metal nozzles generally include methods such as electric discharge machining, laser machining, and electroforming. Among them, it is difficult to prepare the micro-tool electrodes required for the micro-holes of EDM, so it is difficult to be widely used; the micro-holes formed by laser processing will inevitably produce recasting layers or even micro-cracks, and there are tumors at the port below the small holes. Accumulation is not suitable for processing holes with high requirements on hole wall ...
