[0016] This utility model provides a device for forming the sinking of aircraft profiles, such as... Figure 1-3 As shown, it includes an upper template 101, which is connected to an upper top plate 102. The upper top plate 102 is connected to a left upper pressure block 104 and a right upper pressure block 105 on the side away from the upper template 101 through a first connecting component and a second connecting component, respectively. The bottom surfaces of the left upper pressure block 104 and the right upper pressure block 105 are not on the same plane. An upper elastic rubber block 103 is provided between the left upper pressure block 104 and the upper top plate 102. It also includes a lower mold 200, in which a replacement mold assembly is sandwiched. The replacement mold assembly is arranged opposite to the left upper pressure block 104 and the right upper pressure block 105. The upper mold 100 is composed of components such as the upper template 101, upper top plate 102, upper elastic rubber block 103, upper left pressure block 104, and upper right pressure block 105. The upper mold 100 is positioned opposite to the replacement mold assembly in the lower mold 200. The profile 303 is placed on the replacement mold assembly, and the replacement mold assembly is clamped by the lower mold. The lower mold 200 is fixed on the machine tool worktable, and the upper mold 100 is fixed to the machine tool slider. The machine tool stroke is set, the upper mold 100 descends, pressing the profile 303 down to the set depth to form a depression, and the upper mold 100 returns to remove the formed workpiece. The mold assembly can be replaced according to the shape of the profile 303, without the need to replace the upper mold 100 and the lower mold 200, which saves costs, shortens the replacement time, and greatly increases production efficiency.

[0017] Example 1 The device for forming aircraft profiles includes an upper template 101, which is connected to an upper top plate 102. The upper top plate 102 is connected to a left upper pressure block 104 and a right upper pressure block 105 on the side away from the upper template 101 via a first connecting component and a second connecting component. The bottom surfaces of the left upper pressure block 104 and the right upper pressure block 105 are not on the same plane. An upper elastic rubber block 103 is provided between the left upper pressure block 104 and the upper top plate 102. The device also includes a lower mold 200, in which a replacement mold assembly is sandwiched. The replacement mold assembly is positioned opposite to the left upper pressure block 104 and the right upper pressure block 105.

[0018] The first connecting component includes a connecting block 106, with a connecting rod 107 extending through the connecting block 106 along its length. The bottom surface of the connecting block 106 has grooves on both opposite sides along its length. A left upper pressure block 104 is disposed within the groove. A groove is formed in the upper top plate 102, and an upper elastic rubber block 103 is disposed within the groove. A circular hole is formed in the inner wall of the groove, and one end of the connecting rod 107 matches the circular hole. A through hole is formed on the side wall opposite the circular hole in the groove, through which the connecting rod 107 passes. There is a 9mm height difference between the left upper pressure block 104 and the right upper pressure block 105. During the downward movement of the upper mold 100, the left upper pressure block 104 first contacts the profile 303 for positioning. As the upper mold 100 continues to move downward, the right upper pressure block 105 contacts the profile 303 and presses down to determine the depth of the profile 303's depression. During this process, the left upper pressure block 104 compresses the upper elastic rubber block 103 through the connecting block 106. The dimensions of the round hole and the through hole are larger than the dimensions of the connecting rod 107, ensuring that the upper left pressure block 104 can drive the connecting block 106 to move smoothly upward during the downward movement of the upper mold 100. The upper left pressure block 104 is installed on the bottom surface of the connecting block 106 through a slide groove for easy replacement. During operation, the end of the connecting rod 107 is connected to the limiting rod 109.
