[0014] like Figure 1 As shown, the present invention provides a technical solution: a method for processing an aluminum honeycomb panel, comprising the following steps: Obtain an aluminum honeycomb material, and attach a label to a long axial reference edge of the aluminum honeycomb material to form a workpiece to be processed with a reference mark; Fix the workpiece to be processed on the water jet cutting workbench and use the water jet cutting equipment to cut the surface of the workpiece to be processed. The process of water jet cutting of the surface of the workpiece to be processed is as follows: Install an infrared locator on the spindle of the water jet cutting equipment, adjust the spindle of the mobile equipment, and adjust the infrared light spot of the infrared locator to align with the long axial core grid of the workpiece to be processed, that is, the workpiece to be processed is consistent with the engineering requirements; The water pressure, abrasive flow rate and moving speed of the abrasive nozzle of the water jet cutting equipment are adjusted to process the workpiece. The moving speed of the abrasive nozzle is calculated by formula (1), which is as follows: F=t×n×s In the formula: F represents the equipment processing feed speed; t represents the part thickness; n represents the material core size; s represents the sand removal rate.

[0015] In this embodiment, an aluminum honeycomb panel of 450mm×500mm size is used, and the water cutting equipment uses a water pressure of 30Mpa, an abrasive flow rate of 0.01kg / min, and an abrasive nozzle moving speed of 50mm / min to cut the aluminum honeycomb panel. A reference mark is formed by affixing a label to the long axial reference edge of the aluminum honeycomb material, and a coordinate system is established with the reference mark as a reference basis. The aluminum honeycomb material is cut by using the water cutting equipment, which effectively reduces the production cost and solves the problem of extrusion deformation of the honeycomb contour processing.

[0016] After the aluminum honeycomb panel is cut, the cut aluminum honeycomb panel is cleaned. The cleaning process is as follows: The honeycomb surface of the workpiece to be processed is rinsed with tap water, and the diamond grit and debris on the honeycomb surface are visually checked until there is no diamond grit and debris on the honeycomb surface. Then, compressed air is sprayed to the honeycomb surface through air compression equipment to complete the cleaning of the diamond grit and debris on the honeycomb surface. After the cleaning is completed, the cut piece is obtained.

[0017] Place the cut piece on the five-axis machine tool, adjust the cut piece to align with the X-axis of the five-axis machine tool through the infrared device, and position the cut piece on the five-axis machine tool. The positioning process of the cut piece on the five-axis machine tool is as follows: Use adhesive to bond the cut piece to the fitting surface of the tooling. According to the reference mark on the cut piece, use the infrared locator on the five-axis machine tool to limit the cut piece on the five-axis machine tool. Turn on vacuum adsorption to limit the cut piece to the predetermined position on the five-axis machine tool.

[0018] After the positioning of the cut piece is completed, the machining coordinate system is established, and the machined piece is machined by a five-axis machine tool. The machining process of the five-axis machine tool is as follows: A combined honeycomb milling cutter is used to perform rough and fine processing on the cutting piece. In the present embodiment, the combined honeycomb milling cutter adopts a crushing body and a honeycomb blade which are fixed by bolts to form a combined honeycomb milling cutter. In the process of using the combined honeycomb milling cutter to process the cutting piece, the cutting piece is firstly rough-processed. The surface of the workpiece is rough-processed with a spindle speed of 12000rpm, a rough processing feed of 2000mm / min, and a single-layer cutting depth of 3mm. After the rough processing is completed, fine processing is performed. In the fine processing process, the spindle speed is 12000rpm, the fine processing feed is 500mm / min, and the single-layer cutting depth is 0.3mm. The surface of the workpiece is fine-processed. After the fine processing is completed, compressed air is used in combination with tweezers to clean up the metal debris remaining on the surface of the workpiece, and the surface processing of the cutting piece can be completed to obtain the workpiece.

[0019] Move the workpiece to the water jet cutting equipment, adjust the workpiece to align with the main axis of the water jet cutting equipment, set the processing reference for water jet cutting, and clean it after the processing is completed to obtain the aluminum honeycomb parts. The water jet cutting process of the outline of the workpiece is as follows: Install the workpiece on the water jet cutting equipment, adjust the main shaft of the equipment through the infrared locator on the main shaft of the water jet cutting equipment, and adjust the infrared light spot of the infrared locator to align with the long axial core grid of the workpiece to be processed, that is, the workpiece is consistent with the engineering requirements; The contour of the workpiece is processed by adjusting the water pressure, abrasive flow rate and moving speed of the abrasive nozzle of the water jet cutting equipment. The moving speed of the abrasive nozzle is calculated by formula (1), which is as follows: F=t×n×s Where: F represents the processing feed speed of the equipment; t represents the thickness of the part; n represents the size of the material core grid; s represents the sand removal rate. In this embodiment, the contour of the aluminum honeycomb panel with a size of 450mm×500mm is subjected to water cutting. During the cutting process, the water cutting equipment uses a water pressure value of 30Mpa, an abrasive flow rate of 0.05kg / min, and an abrasive nozzle moving speed of 50mm / min to cut the contour of the aluminum honeycomb panel, and obtains a circular workpiece with a diameter of 400mm.

[0020] After the contour water cutting of the workpiece is completed, the honeycomb surface of the workpiece that has completed the contour cutting is rinsed with tap water, and the diamond sand and debris on the honeycomb surface are visually checked until there is no diamond sand and debris on the honeycomb surface. Compressed air is sprayed to the honeycomb surface through air compression equipment to complete the cleaning of the diamond sand and debris on the honeycomb surface. During the water cutting process, the aluminum honeycomb panel will not expand, warp or deform along the cutting edge due to high temperature, thereby reducing the generation of burrs, and there is no need to grind the aluminum honeycomb panel, shortening the processing process of the aluminum honeycomb panel. The surface of the workpiece is rinsed with tap water to obtain aluminum honeycomb parts.

[0021] The preferred embodiments of the present invention are described in detail above; however, the present invention is not limited to the specific details in the above embodiments.
