Embodiment 1

[0024] The surface of the selected aluminum plate with a thickness of 1.5 mm, 5.0 mm, and 5.0 mm is roughened with a wire roller brush, and the aluminum powder attached to the surface is blown off with 0.3-0.8 MPa dry air. After the temperature of the aluminum plate dropped to room temperature, different graphite circuit diagrams were printed on the two polished surfaces of the aluminum plate with a thickness of 1.5 mm. Two aluminum plates with a thickness of 5.0 mm sandwich a 1.5 mm thick aluminum plate with graphite line patterns on both sides, and the three sides are aligned and riveted along the edges. After the riveted aluminum plate is heated by the heating furnace, it is sent to the hot rolling mill for rolling. According to the requirements of different specifications, the aluminum plate of the required length can be obtained. Anneal the aluminum plate with qualified length in the annealing furnace and cool it to room temperature; drill a process hole on the graphite l...

Abstract

The invention relates to a double-faced flat-bulging process of a pure aluminum panel. The double-faced flat-bulging process comprises the following steps of a. roughening and blowing down the surfaces of three shearing-formed aluminum panels with different thicknesses; b. forming different graphite lines on two roughened surfaces of a thinner aluminum panel by using a graphite printing method; c. jointing two surfaces of the thinner aluminum panel with roughened surfaces of two thicker aluminum panels, aligning three sides, riveting along the edges; d. heating the aluminum panels in a continuous heating furnace to a certain temperature and maintaining for a certain time, carrying out hot rolling to form a composite aluminum panel after taking out; e. softening and annealing the composite aluminum panel, cooling, then drilling a process hole in a position of the aluminum panel graphite line to a graphite layer, and prying an opening in an air inlet pipe; and f. placing the composite aluminum panel on a large-tonnage oil press bulged template, aligning the process hole to an air inlet, jointing an upper template on the upper surfaces of the aluminum panels, filling high-pressure fluid in a pipeline until the pipeline expands to form a composite aluminum panel with two smooth surfaces and a groove channel formed in the interlayer in the middle. A composite aluminum panel pipeline bulged by using the process is high in jointing strength, and is capable of bearing high pressure without deforming.

Description

technical field [0001] The invention relates to an inflation process for compounding and forming complex internal channel network with three layers of aluminum plates. In particular, it is a process in which both sides are flat and the middle interlayer forms a channel. Background technique [0002] In the prior art, a double-layer aluminum plate with similar thickness and compounded with different materials is used, and one side of the duralumin plate is smoother after bulging. When it is used in the refrigeration parts of the refrigerator system, the pipeline works in a negative or low pressure state, and the flat surface will not be damaged. However, when the internal pipeline of the composite aluminum plate is under high pressure, the flat surface is easily damaged, which cannot meet the requirements of use. Contents of the invention [0003] The object of the present invention is to provide a double-sided flat inflation process for pure aluminum plates, which mainly...
