Control system and machining method of door and window aluminum profile vacuum casting

Abstract

The invention discloses a control system and a machining method of door and window aluminum profile vacuum casting. The control system comprises a vacuum pressure controller and a temperature controller, wherein the vacuum pressure controller and the temperature controller are connected with the PLC, wherein the vacuum pressure controller is connected to a outdoor cooling vacuum pump which is connected with a vacuum airtight pouring chamber with 0.7 to 0.8 MPa through a pouring vacuum pump to control the cooling vacuum pump to be in an vacuum state; and is connected with a vacuum dust-free closed cooling chamber with 0.8-0.9 MPa to control the vacuum dust-free closed cooling chamber to be in the vacuum state; and a pouring temperature sensor 7 of the vacuum airtight pouring chamber with 0.7 to 0.8 MPa, a cooling temperature sensor of the vacuum dust-free closed cooling chamber with 0.8-0.9 MPa and aluminum alloy section spraying and a drying temperature sensor of a curing and drying room are connected with the temperature controller. The aluminum alloy door and window manufactured by using the vacuum pouring control system and the method machining technology are strong in weather resistance and corrosion resistance, the appearance quality is good, the system and method can be used in various climate environments, and a anti-fatigue performance is good, the system and the methodare wide in application range and long in overall service life.

Description

technical field [0001] The invention relates to the technical field of aluminum profiles, in particular to a control system for vacuum pouring of aluminum profiles for doors and windows and a processing method thereof. Background technique [0002] When the existing aluminum material is processed, especially when it is processed into aluminum rods, customers have different requirements for different specifications of aluminum rods, and it is necessary to add various ingredients to the molten aluminum after the aluminum material is melted to meet the needs of customers; Therefore, there is currently a heat preservation furnace used for heat preservation during batching of molten aluminum, which can perform heat preservation during batching of molten aluminum to ensure that the molten aluminum and ingredients can be fully fused. However, the existing holding furnaces of this type will generate and discharge certain flue gas and exhaust gas during use, causing certain environme...

Problems solved by technology

[0004] Although this application makes full use of the waste heat generated in the holding furnace and purifies the flue gas generated in time to achieve the effect of environmental protection, the heat collecting furnace and the heat collecting casting unit on the top occupy a large space, and the structure of the entire processing system is comparatively relatively large. Huge, with many overall support structures and complex

In addition, for the aluminum alloy profiles used in doors and windows, the thermal insulation structure and system practicability are not very good
