Изобретение относитс к производству изделий из композиционных материалов.The invention relates to the manufacture of products from composite materials.

Известно устройство дл формовани композиционных материалов, содержащее пресскамеру , состо щую из основани н крышки, оправки с осевыми отверсти ми, эластичного чехла н KOMneHCHpjToiaHx прокладок 1.A device for molding composite materials is known, comprising a press chamber consisting of a base n of a cap, a mandrel with axial holes, an elastic cover on KOMneHCHpjToiaHx gaskets 1.

Известное устройство позвол ет изготовить только одно изделие.The known device permits the manufacture of only one product.

Наиболее близким к предлагаемому вл етс устройство дл формовани изделий из композиционных материалов, включающее корпус с крышкой и основанием и установлен1ШЙ в нем р д параллельных формующих эластичных диафрагм, образующих камеры давлени , установленные с зазором 2.Closest to the present invention is a device for molding articles made of composite materials, including a body with a lid and a base and installed in it a number of parallel forming elastic diaphragms forming pressure chambers mounted with a gap 2.

Данное устройство не обеспечивает удалени воздушных включений в изделии,This device does not remove air inclusions in the product,

Цель изобретени - повышение качества изделий и надежиости работы устрсйства.The purpose of the invention is to improve the quality of products and the reliability of the operation of the device.

Поставлети цель достигаетс за счет того, что в устройстве, дл формовани изделий из композиционных материалов, включающемThe goal is achieved due to the fact that in the device for molding articles from composite materials, including

корпус с крышкой и основанием и установленный в нем р д параллельных формующих эластичных диафрап(, образующих камеры давлени , установленные с зазором, диафрагмы попарно соединены вогнутыми вовнутрь жесткими злементами, образующнми боковые поверхности камер, снабженных пггуцерами хш соединени с системой вакуумнровани .a housing with a lid and a base and a series of parallel forming elastic diaphragms installed therein (forming pressure chambers installed with a gap, the diaphragms are connected in pairs by concave inward rigid elements forming the lateral surfaces of chambers equipped with hsh connection with a vacuum system.

При зтом под нижней диафрагмой каждой вакуумной KaAfepb установлен перфорнрованный металлический лист.At this, a perforated metal sheet is installed under the lower diaphragm of each vacuum KaAfepb.

На фиг. 1 изображено предлагаемое устройство , общий вид; на фиг. 2 - то же, вид в плане.FIG. 1 shows the proposed device, a general view; in fig. 2 - the same plan view.

Устройство включает о(нование 1 с крышкой 2 и установленный в нем р д зластичных диафрагм 3, образующих камеры 4 давлени и вакуумные камеры 5.The device includes about (innovation 1 with cover 2 and a row of elastic diaphragms 3 installed therein, forming pressure chambers 4 and vacuum chambers 5.

Claims

The pressure chambers 4 are interconnected and with the supply system of the working medium by the pipeline 6. The vacuum chambers 5 are connected to each other with the vacuum system of the pipeline 7. E9 To reduce the concentration (rigid side walls 8 of the chambers 5 on the flexible diaphragm, the evacuations are concave inward and fastened together 9. A perforated metal sheet is installed under the lower diaphragm 3 of each vacuum chamber 5. 10. Boops 11 connect the cover 2 and the base 1. Thermolars 12 are installed in the ratchet 2 and the base 1. The solvency works as follows: When the cover 2 is removed, the elastic diaphragms 3 of the vacuum strips 5 of the composite material are placed on the bottom 2. The perforated 1 metal sheets 10 prevent the diaphragm 3 from sagging, and then the base 1 with the cover 2 is bolted 11. Pipelines 6 are connected in series to pressure gauge 4, and pipelines 7 in parallel are connected to vacuum chambers 5. The mounted device is interfered with in a thermo-furnace and then connected to vacuum systems and supplying the working medium, the output thermo a predetermined temperature. Under the action of vacuum in chambers 5 and the pressure of the upper and lower. elastic diaphragms 3, the product is pressed. On heating the device in thermal furnace provides curing. After molding, the device is removed from the thermal furnace, the finished products are demonstrated and removed. Then the work is repeated. The implementation of the proposed device allows to improve the quality of the molded products, in addition, the reliability of its operation is enhanced by the design of vacuum chambers with lateral rigid elements and. Claim 1. A device for forming articles made of composite materials, comprising a housing with a ratchet and base and a number of parallel forming elastic elastic diaphragms installed therein, forming pressure chambers, which are designed so as to improve the quality products and reliability of operation of the device, diaphragms are pairwise connected by rigid elements into the air, rigid elements forming the side surfaces of the chambers equipped with fittings for connection to the vacuum system and. 2. The device according to claim 1, of which there is a perforated metal sheet below the bottom diaphragm of each vacuum chamber. Sources of information taken into account in the examination 1.
