[0024] The present invention also provides a method for molding a composite material of an aero-engine air intake duct, and the molding method is as follows:
[0025] S1: Place the workpiece to be processed under the moving device and start the machine, so that the moving device is lowered and the lifting rod is lowered by the cylinder, and the support rod is supported by the push block and the contact ball so that the support plate supports the inner wall of the workpiece to be processed and moves;
[0026] S2: Before the moving device places the part to be processed on the top surface of the turntable, the clamping device is controlled to clamp the reinforcing rib and place it on the top surface of the turntable. When the moving device drives the part to be processed to be placed on the top surface of the turntable, the clamping device starts to move up and down, and stops moving when it is adjusted to a suitable position;
[0027] S3: At this time, the movable welding device 1 is lowered to the upper side of the reinforcing rib, and the movable welding device 2 is raised to the lower side of the reinforcing rib, and the welding is started after the movable welding device 1 and the movable welding device 2 are adjusted to the specified position;
[0028] S4: During welding, the turntable rotates at a constant speed, so that the movable welding device 1 and the movable welding device 2 weld the entire circle of the upper and lower sides of the reinforcing rib. After welding, the movable welding device 1 and the movable welding device return to their original positions, the parts to be processed are removed, and the moving device is used to move the parts to be processed to the outside of the part fixing block. At this time, the hydraulic rod 3 is started to move the molds on both sides of the carbon fiber mold;
[0029] S5: After the carbon fiber mold completely wraps the part to be processed, connect the hose and inject the hot-melt carbon fiber material into the mold. After cooling, start the hydraulic rod 3 to separate the molds on both sides and remove the processed air intake duct.
[0030] Compared with the prior art, the present invention provides an aircraft engine air intake composite molding equipment and molding method, which has the following beneficial effects:
[0031] 1. The composite material forming equipment and forming method of the aircraft engine air intake duct, first, place the part to be processed under the moving device and start the machine, so that the moving device is lowered and the lifting rod is lowered by the cylinder, and the support plate is supported and moved by the push block and the contact ball to support the inner wall of the part to be processed. The layer of rubber anti-skid material covered on the surface of the support plate has a good anti-skid effect, which not only ensures that the possibility of the part to be processed falling can be reduced during movement, but also avoids the material of the inner wall being damaged by the support plate when supporting the inner wall. Before the moving device places the part to be processed on the top surface of the turntable, the clamping device is controlled to clamp the reinforcing rib and place it on the top surface of the turntable. When the moving device drives the part to be processed to be placed on the top surface of the turntable, the clamping device starts to move up and down to adjust the welding position of the reinforcing rib. When it is adjusted to a suitable position, it stops moving. At this time, the movable welding device first descends to the upper side of the reinforcing rib, and the movable welding device second rises to the lower side of the reinforcing rib.
[0032] 2. The composite material forming equipment and forming method of the aircraft engine air intake duct starts welding after the movable welding device 1 and the movable welding device 2 are adjusted to the appropriate position. The welding device that can adjust the position can adjust the position according to the size of the part to be processed. The electric telescopic rod that can be extended up and down also allows welding when facing parts with different positions of the reinforcement ribs, which further improves the use scenario of the machine. During welding, the turntable rotates at a uniform speed, so that the movable welding device 1 and the movable welding device 2 weld the upper and lower sides of the reinforcement ribs in a full circle, avoiding the need to use manpower to weld the reinforcement ribs in a full circle in the processing cabinet, saving the company's labor costs. After welding is completed, the movable welding device 1 and the movable welding device return to their original positions, remove the parts to be processed, and use the movable welding device 1 to weld the parts to be processed. The moving device moves the part to be processed to the outside of the part fixing block. At this time, the hydraulic rod three is started to move the molds on both sides of the carbon fiber mold. After the carbon fiber mold completely wraps the part to be processed, the hose is connected to inject the hot-melt carbon fiber material into the mold. After cooling, the hydraulic rod three is started to separate the molds on both sides and the processed air intake duct is removed. Carbon fiber composite materials have high vibration damping, can effectively absorb and disperse vibration energy, thereby reducing structural vibration and noise, have good resistance to chemical substances such as acids, alkalis, and salts, are not easily corroded, and can maintain their physical and chemical properties in high temperature environments. When impacted, they can effectively absorb impact energy, thereby reducing damage to the structure and improving the safety of vehicles, which is particularly important in fields such as aerospace.
