Problems solved by technology

[0005] The above solution solves the problems of easy degumming and low strength of the honeycomb panel during use, and obtains a brazed metal honeycomb panel with high strength, high rigidity, heat insulation and sound insulation, and low cost
But the above-mentioned scheme still does not solve the defect that is easy to be deformed at high temperature during brazing

Embodiment Construction

[0030] Such as Figure 1-3 Shown, a kind of manufacturing process of glue-free composite board comprises the following steps:

[0031] A. Making plates and cores: get aluminum plates and cut them into blocks for later use to obtain composite plates; take aluminum foil to make honeycomb cores and cut them into sizes corresponding to the composite plates to obtain cores;

[0032] B. Assembly: smear flux on the upper and lower surfaces of the core, and cover the upper and lower surfaces of the core with composite plates to obtain a block-shaped composite honeycomb panel, and clamp the composite honeycomb panel with a fixture;

[0033] C. Brazing: Dry the composite honeycomb panel and put it into a brazing furnace for brazing to obtain a glue-free composite panel.

[0034] Because the composite honeycomb board is clamped by the fixture, the composite board and the board core will not be deformed during high-temperature brazing, thereby improving the manufacturing quality. Therefo...

Abstract

The invention provides a self-bonding composite board and a manufacturing process thereof and belongs to the technical field of soldering. The manufacturing process comprises the steps of A, manufacturing board bodies and board cores, wherein an aluminum board is cut into blocks so that the board bodies for composition can be obtained, honeycomb cores are manufactured with aluminum foil and cut into a size corresponding to that of the board bodies for composition so that the board cores can be obtained, and the board bodies for composition and the board cores can be machined with corresponding dies manufactured according to different specification requirements; B, conducting assembly, wherein the upper surface and lower surface of each board core are smeared with soldering flux and covered with the corresponding board bodies for composition to obtain a blocky composite cellular board, and the composite cellular boards are clamped to be shaped with a clamp; C, conducting soldering, wherein the composite cellular boards are dried and fed into a soldering furnace to be soldered so that the self-bonding composite board can be obtained. According to the self-bonding composite board and the manufacturing process thereof, deformation of the composite board during high-temperature soldering can be prevented, so that soldering quality is improved, production cost is reduced and the high-quality self-bonding composite board is obtained.

Description

technical field [0001] The invention belongs to the technical field of brazing, and relates to a glue-free composite board and a manufacturing process thereof. Background technique [0002] Brazing is to use a metal material with a lower melting point than the base metal as the solder, heat the weldment and the solder to a temperature higher than the melting point of the solder and lower than the melting temperature of the base metal, use liquid solder to wet the base metal, fill the gap between the joints and The method of interdiffusion with the base metal to realize the connection of the weldment. The brazing deformation is small, and the joint is smooth and beautiful. It is suitable for welding precision, complex and components composed of different materials, such as honeycomb structure plates, turbine blades, hard alloy tools and printed circuit boards. Before brazing, the workpiece must be carefully processed and strictly cleaned to remove oil stains and excessively ...
