Technical field

The present invention relates to wire mesh edge bonding methods in aircraft engine nacelle ventilation cooling system.

Background technique

In the dynamical system design installation of aircraft, to guarantee that engine indoor environment temperature meets accessory temperature requirement, Cooling need to be aerated to enging cabin, as ventilating and cooling channel be a kind of common design means using wire mesh, be Meet ventilating and cooling air inflow demand, the wire mesh grid spacing used is larger, when aircraft is in flying for long time, pneumatic Under the action of power, the wire at silk screen edge is easy to take off gradually from edge de-, influences continuing to use for silk screen.Therefore it is designing In, to wire mesh edge sealing, wire mesh running under long-term ventilation vibration environment is prevented, guaranteeing that silk screen does not rupture is a set Count difficult point.Wire mesh running in order to prevent needs to carry out wire mesh edge sealing processing, wire mesh envelope in previous design It being handled when side using wire mesh edge welding metal plate mouth frame, in this kind of processing method, mouth frame sheet metal component needs cut, flange, Then it is welded with silk screen, while 45 ° of oblique angle butt welding.Existing edge bonding method has a defect that constitutional detail is more, processes work Skill is complicated, and manufactured pts wt is big, and in use silk screen silk material easily with mouth frame desoldering, be unfavorable for system use it is safe.

Summary of the invention

The application's is designed to provide a kind of wire mesh edge bonding method, realizes under the premise of not increasing component part Edge sealing is carried out to wire mesh, wire mesh running under long-term ventilation vibration environment can be prevented, silk screen does not rupture.

A kind of wire mesh edge bonding method, it is characterised in that include the following contents: 1) to the region on wire mesh periphery into Row electroplating processes determine the edge sealing region for needing edge sealing, and the region of electroplating processes is greater than edge sealing region；2) to wire mesh Edge sealing carries out cored solder filling, the wire mesh grid in edge sealing region is filled up with cored solder, the two of wire mesh edge sealing region Side forms cored solder coating；Wire cross point in wire mesh edge sealing region is completely covered cored solder coating.

The wire mesh edge sealing peak width is 3~4 times of adjacent wire spacing.

The beneficial effects of the present application are as follows: 1) using method that plating and soldering combine in the neighboring area of wire mesh The silk screen edge sealing of the integral structure of cored solder covering wire is formed, part manufacture craft is simple, and manufacturing cost is low, pts wt It is lighter than the edge sealing part of traditional metal plate soldering opening frame.For aircraft under long-term high-altitude flight vibration environment, silk screen edge sealing is reliable, solid Fixed secured, not running, ventilating and cooling work well, and meet the use technical requirements of aircraft and engine.2) silk in the application Net edge sealing, edge sealing region can also be used in the connection impetus of silk screen and housing construction, and silk screen installation is very convenient.3) the edge sealing skill Art is to silk screen shape without particular/special requirement, it is convenient to make edge sealing to special-shaped shape (the non-directional silk screen in edge).

Attached drawing is described in further detail the application with reference to embodiments.

Fig. 2 is edge sealing region A-A profile structure diagram in Fig. 1.

Explanation: 1 wire mesh, 2 edge sealing regions, 3 cored solder coatings, 4 wire cross point is numbered in figure

Specific embodiment

Referring to attached drawing, cored solder adhesion-tight when in order to guarantee to carry out wire mesh edge sealing soldering, before edge sealing soldering Electroplating processes must be carried out using with soldering identical metal to metal silk screen neighboring area, the region of electroplating processes is greater than envelope Border region can also all carry out electroplating processes to wire mesh in implementation, could guarantee that the edge sealing of wire mesh is uniform in this way, Silk screen crosspoint is firmly bonded, and edge sealing region is smooth, is fixed convenient for later period installation.
