Abstract

The invention provides a kind of aviation composite part spray painting Design of Production Line method, it is characterized in that, set gradually paint spray booth, levelling room and drying chamber, paint spray booth, levelling room and drying chamber are connected by anti-explosion electric rolling screen door, part is set to be sprayed in paint spray booth, stopped more than half an hour in the levelling room for possessing filtering dust ability, the solvent in paint film is set slowly to volatilize, avoid in drying chamber making solvent drastically volatilize to cause coating surface the defects such as substantial amounts of pin hole occur because temperature increases, so that part is in spray painting, levelling and dry overall process be in cleaning ambient in, ensure piece surface painting quality.

Description

A kind of aviation composite part spray painting Design of Production Line method

Technical field

The invention belongs to machining technology field.

Background technology

By situation investigation of being painted to domestic several main engine plants' composites, the surprising phase of the spray painting problem of each main engine plants is perplexed at present Seemingly, dust falls after rise after being concentrated mainly on spray painting, causes coating surface particle, grows dim, solidifies the defect such as bad.

Domestic composite painting line is roughly divided into two kinds of forms：Set in worker-house without being set in pump water curtain coating booth or worker-house Put " room in room " form of paint spray booth.The production line of the first form, because ventilation volume is big in worker-house, humiture and air are clear Cleanliness can not be controlled effectively, and surface quality of workpieces is poor after spray painting.Second production line of form, is unidirectional entrance and exit type layout, Part levelling region after special spray painting is not provided with, after workpiece is painted or spray painting area resource is taken, or non-clean area is placed on Domain.Workpiece is had to by Polluted area between paint spray booth and drying chamber in circular flow, causes the coating surface of workpiece to produce The defects such as particle.

The content of the invention

According to composite material parts painting process, reasonable design technology layout improves composite material parts painting environment control accuracy, Make to be completely under cleaning ambient during part spray painting to drying, dust falls the film defect for causing after rise after solving spray painting.

A kind of aviation composite part spray painting Design of Production Line method, according to composite material parts painting process, spray painting is produced Line is designed as " room in room " formula structure, sets gradually paint spray booth, levelling room and drying chamber, paint spray booth, levelling room and drying chamber Connected by anti-explosion electric rolling screen door,

Part is sprayed in paint spray booth, stopped more than half an hour in the levelling room for possessing filtering dust ability, make molten in paint film Agent is slowly volatilized, it is to avoid make solvent drastically volatilize to cause coating surface substantial amounts of pin hole etc. occur because temperature increases in drying chamber Defect so that part spray painting, levelling and dry overall process be in cleaning ambient in, it is ensured that piece surface painting quality.

Rationally, its function fully meets expected design for the set painting line process layout and flow scheme design, especially to ash after spraying The phenomenon that dirt descends slowly and lightly prevents substantially.By spraying Boeing product, its spray painting first-time qualification rate reaches more than 90% from 82% lifting, Spray painting pays qualification rate up to 98%.Coming into operation for the production line, improves the environment of composite spray painting, is greatly enhanced Painting quality, reduces the turnover repeatedly during part spray painting, improves production efficiency, effectively alleviates composite spray The bottleneck effect of paint, improves painting quality.

Specific embodiment

Painting line is designed as " room in room " formula structure according to composite material parts painting process, i.e., is set in spray painting factory building Put professional paint spray booth, levelling room and drying chamber.Special cleaning region is set used as stream between traditional spray painting and drying simultaneously Flat room, is the integrated design " by formula " by paint spray booth, levelling room and drying chamber layout, and each equipment room is rolled up by anti-explosion electric Curtain door is connected, and part is sprayed in the paint spray booth that humiture, air cleanliness, laminar flow wind speed can be effectively ensured, and is possessing ash Stopped more than half an hour in the levelling room of dirt filter capacity, the solvent in paint film is slowly volatilized, it is to avoid due to temperature in drying chamber Degree increases to be made solvent drastically volatilize to cause coating surface the defects such as substantial amounts of pin hole occur, so that part is in spray painting, levelling and dry Dry overall process is in cleaning ambient, it is ensured that piece surface painting quality.

Each primary parameters of test apparatus is shown in Table 1.

Table 1 passes through each primary parameters of test apparatus of formula painting line

Claims (1)

1. a kind of aviation composite part spray painting Design of Production Line method, it is characterised in that set gradually paint spray booth, levelling Room and drying chamber, paint spray booth, levelling room and drying chamber are connected by anti-explosion electric rolling screen door,

Part is sprayed in paint spray booth, stopped more than half an hour in the levelling room for possessing filtering dust ability, make molten in paint film Agent is slowly volatilized, it is to avoid make solvent drastically volatilize to cause coating surface substantial amounts of pin hole etc. occur because temperature increases in drying chamber Defect so that part spray painting, levelling and dry overall process be in cleaning ambient in, it is ensured that piece surface painting quality.
