Their unique performance advantages have made composite materials widely used in the aviation field.

[0003] At present, the conventional manufacturing route of composite materials is to first use composite forming tooling to autoclave curing and forming, and then use the milling tooling designed to match it for CNC machining. This has the disadvantages of long process cycle, high processing cost and low efficiency. In addition, because composite materials are cured and formed at high temperature in autoclaves, they expand due to heat. After the product is demoulded, it is transferred to the milling tooling for processing. Repeated positioning will lead to inaccurate product positioning and poor matching with the tooling. At the same time, the cumulative manufacturing errors of composite forming tooling and milling tooling lead to great difficulty in product processing, low product qualification rate and high scrap rate.

DETAILED DESCRIPTION

[0027] The present invention is further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0028] like Figure 1-Figure 4 As shown, a composite material forming and milling integrated tooling for reinforced wall panels includes a tooling body 1, an insert 2, a machine pressure plate 3, a gantry 4, a rib forming die 5 and a drilling jig assembly 6. The top surface of the tooling body 1 is provided with a product laying area adapted to the product shape, and the product laying area is reserved with a laying margin; the insert 2 is configured to form a tooling profile with the tooling body 1 so that the wall panel can be laid and formed on the tooling profile; the machine pressure plate 3 is configured to perform shape processing on the wall panel; the gantry 4 and the rib forming die 5 are configured to glue the processed wall panel and the ribs to form a reinforced wall panel; the drilling jig assembly 6 is configured to process positioning holes for the reinforced wall panel.

[0029] like Figure 1 , Figure 2 As shown, the insert 2 is detachably mounted on the tooling body 1 and located at the center of the product paving area. Specifically, an inlay hole matching the shape of the insert 2 is opened on the tooling body 1 at the center of the product paving area, and the insert 2 is embedded in the inlay hole from the bottom of the tooling body 1 and connected to the bottom of the tooling body 1 through a locking screw 7.

[0030] After installing the inlay 2, the composite material is laid around the inlay 2 in the product laying area, and then the composite material is hot-pressed and cured into shape. Finally, the surface of the formed wall panel is directly CNC-machined without demolding. Since the CNC-machined area on the wall panel needs to be kept away from air, the inlay 2 needs to be removed from the bottom of the tooling body 1 before CNC-machining the formed wall panel.

[0031] like Figure 1 , Figure 5As shown, the machine pressure plate 3 is detachably arranged on the top of the tooling body 1 on both sides of the product paving area. Specifically, a waist-shaped groove 8 is provided on the machine pressure plate 3, and a clamping screw 17 threadedly connected to the tooling body 1 is inserted into the waist-shaped groove 8, and the waist-shaped groove 8 is slidably connected to the clamping screw 17. After the surface processing of the wall panel is completed, the position of the machine pressure plate 3 is adjusted by the relative sliding of the waist-shaped groove 8 and the clamping screw 17, so that the machine pressure 3 can press the wall panel without affecting the processing of the wall panel, and then tighten the clamping screw 17 to press the machine pressure plate 3 on the tooling body 1 to complete the fixation of the machine pressure plate 3, and then the wall panel is pressed by the machine pressure plate 3, and then the shape of the wall panel can be CNC processed, and the machine pressure plate 3 can be removed by removing the clamping screw 17.

[0032] like Figure 1 , Figure 3 As shown, the gantry 4 is detachably arranged on the top of the tooling body 1, and the rib forming mold 5 is positioned in the product paving area through the gantry 4. The number of rib forming molds 5 is selected according to the number of rib installation requirements. In this embodiment, six forming molds are provided. Specifically, the gantry 4 is a steel structure, which is welded from square steel of different specifications. The gantry 4 is plugged with the top of the tooling body 1 through the first positioning pin 9, and the gantry 4 is connected to the top of the tooling body 1 through the locking screw 7. The gantry 4 is positioned on the tooling body 1 through the first positioning pin 9 and then fixed through the locking screw 7. When gluing the ribs, the ribs are first laid on the bottom of the rib forming mold 5, and then the gantry 4 is installed to position the rib forming mold 5 at the gluing position of the ribs. After the rib forming mold 5 is positioned, the gantry 4 is removed, and then the bag is sealed on the positioning column 10 and the gantry 4 is installed. The gantry 4 is positioned through the first positioning pins 9 of different specifications so that the ribs are glued to the wallboard along the positioning direction.

[0033] Since the installation and positioning of the ribs on the product is unique, in order to prevent the product from being scrapped due to the wrong hinge of the ribs, it is necessary to carry out an error-proofing design on the positioning of the rib forming mold 5 to ensure the processing accuracy. For this, a positioning column 10 is fixed on the top of the rib forming mold 5, and two positioning sockets are provided on the positioning column 10, and the apertures of the two positioning sockets on the positioning column 10 are different. A positioning support 11 corresponding to the positioning sockets is fixed on the gantry 4, and a second positioning pin 12 plugged into the corresponding positioning socket is provided on the positioning support 11. Since the apertures of the two positioning sockets on the positioning column 10 are different, the size specifications of the two second positioning pins 12 corresponding to the positioning column 10 are different. In this way, when the rib forming mold 5 is positioned, if the direction of the rib forming mold 5 is changed, it cannot be positioned, and the ribs can only be installed in a unique direction. Similarly, the gantry 4 can also be positioned on the tooling body 1 through first positioning pins 9 of different specifications, and the gantry 4 can be prevented from being installed in the wrong direction through the error-proofing design.

[0034] like Figure 1 , Figure 4 As shown, the drilling template assembly 6 is detachably arranged on the top of the tooling body 1 and is located at the edge of the product paving area. The number of drilling template assemblies 6 can be selected according to the number of holes to be drilled. In this embodiment, four sets of drilling template assemblies 6 are provided. Specifically, the drilling template assembly 6 includes a drilling template 61, a drilling sleeve 62 and a limit pin 63. The drilling template 61 is provided with a drill sleeve 62 at one end, and a limit pin 63 plugged into the top of the tooling body 1 is provided at the other end of the drilling template 61. The other end of the drilling template 61 is connected to the bottom of the tooling body 1 through a locking screw 7.

[0035] After the ribs are glued, the ribs can be polished and cut according to the shape of the rib forming die 5 to complete the forming of the wall panel, and then the drilling jig assembly 6 is installed to process the positioning holes of the reinforced wall panel. When installing the drilling jig assembly 6, the gantry 4 and the rib forming die 5 are first removed, and then the drilling template 61 is positioned on the tooling body 1 through the limit pin 63, and the drilling template 61 is fixed by the locking screw 7. After the drilling template 61 is fixed, the reinforced wall panel is drilled through the drill sleeve 62.

[0036] In addition, if Figure 1 As shown, a machining reference hole 13 and a test tool seat mounting hole 14 are provided on the top of the tool body 1. The machining reference hole 13 is used to establish a measurement coordinate system together with a plurality of positioning holes machined on the reinforced wall panel, so that the relevant parameters of the reinforced wall panel can be measured through the measurement coordinate system to see whether they meet the preset machining technical requirements. The test tool seat mounting hole 14 is used to install a test tool seat, so that a test knife is first carried out through the test tool seat before machining to verify whether the positioning is accurate. After the test knife is verified to be qualified, the milling machining of the wall panel is carried out. Lifting rings 15 are installed on the tool body 1 and the gantry 4 to facilitate lifting the tool body 1 and the gantry 4. A forklift hole 16 is provided at the bottom of the tool body 1 to facilitate carrying the tool body 1 by a forklift.

[0037] Based on the above structural description, when the reinforced wall panel is formed and holed by the above reinforced wall panel composite material forming and milling integrated tooling, the specific processing steps are as follows: S1. Install the insert 2 on the tooling body 1, and then lay the composite material around the insert 2 on the product laying area on the tooling body 1. Then, seal the installation area of ​​the insert 2 at the bottom of the tooling body 1 to ensure the air tightness of the tooling as a whole. Finally, put the tooling body 1 into the autoclave and lay the composite material to obtain the wall panel.

[0038] S2. Remove the edge sealing bag at the bottom of the tooling body 1, seal the bag at the paving margin in the product paving area and draw a vacuum to make the wall panel fit tightly with the top surface of the tooling body 1, and perform initial CNC processing on the surface of the wall panel to ensure the surface accuracy of the wall panel.

[0039] S3, remove the insert 2 and install the machine pressure plate 3 on the top of the tooling body 1 to press the wall panel, perform secondary CNC processing on the wall panel, and process the target shape of the wall panel.

[0040] S4, laying ribs at the bottom of the rib forming mold 5, installing the gantry 4 to perform initial positioning on the rib forming mold 5, removing the gantry 4 after the initial positioning of the rib forming mold 5, then sealing the bag on the positioning column 10 and installing the gantry 4, positioning it through first positioning pins 9 of different specifications so that the ribs are glued to the wall panel along the positioning direction to obtain a reinforced wall panel.

[0041] S5. Grind and cut the ribs on the reinforced wall panel according to the shape of the rib forming die 5 to obtain a formed reinforced wall panel, remove the gantry 4 and the rib forming die 5, install multiple sets of drilling jig assemblies 6, and process multiple positioning holes on the reinforced wall panel through the drilling jig assemblies 6.

[0042] S6. The processed reference hole 13 and the processed multiple positioning holes jointly establish a measurement coordinate system, and measure whether the relevant parameters of the stiffened wall panel meet the preset processing technical requirements.

[0043] The tooling of the present invention integrates the composite material forming function and the milling cutting function. After the reinforced wall panel is composite material solidified and formed, the product can be CNC-processed without demolding the product, thereby shortening the manufacturing cycle, improving processing efficiency, and saving processing costs. At the same time, the installation and positioning of the rib forming mold 5 is unique, which can further improve the processing accuracy.
