Description

Technical Field

[0001] The utility model relates to the technical field of wing skin tooling, in particular to a wing lower skin tooling. Background Art

[0002] The wing skin is surrounded by the aircraft wing frame structure and fixed to the wing frame with adhesives or rivets. The skin structure composed of the wing skin and the frame has a large load-bearing capacity and rigidity, but a very light weight, and plays the role of bearing and transmitting aerodynamic loads. Common wing skins include metal skins, composite laminated skins, sandwich skins and integral wall panels. Among them, the metal skin is usually pressed using a tooling as a mold, and the metal skin is molded into a shape corresponding to the mold by pressing the mold in the tooling with the metal skin.

[0003] However, the existing lower wing skin tooling and the tire mold surface are mostly integrated structures, which are not convenient to replace. After pressing a certain number of lower wing skins, the tire mold surface of the tooling is prone to wear, affecting the accuracy of subsequent products. In addition, the existing tooling is mostly customized with the wing frame. When the wing frame design is changed, the tooling needs to be modified synchronously, which increases the cost of use. In order to solve the shortcomings of the existing technology, we propose a lower wing skin tooling. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-Figure 4 As shown, the wing lower skin tooling includes a tooling upper template 1. When the skin is processed, the positioning pin 11 is used to position the tooling upper template 1, and then the hydraulic equipment is used to push the first top plate 14 to push the first fixed frame 13 to push the tooling upper template 1 to push the side mold frame 7. The side mold frame 7 drives the tire template 3 to press the metal plate to be processed between the tooling lower template 8 and the side mold frame 7 by driving the first connecting rod 4 and the second connecting rod 5. The bottom of the tooling lower template 8 and the top of the side mold frame 7 clamp the metal plate to be processed, and then the tire template 3 extrude the metal plate to be processed into the tooling lower template 8 to complete the processing of the skin. The tire template 3 is connected and installed with the side mold frame 7 by the first connecting rod 4 and the second connecting rod 5, and then fixed and positioned by the positioning rod 10. The tire template 3, the side mold frame 7 and the tooling upper template 1 are each independent individuals. Compared with the traditional integrated tooling mold, it is convenient for the staff to separately repair them. The tire template 3 can also be conveniently disassembled and replaced after being worn, so as to maintain the processing accuracy. The surface of the processed skin is smooth and meets the use requirements.

[0023] like Figure 1-Figure 4 As shown, when the tire template 3 customized according to the wing frame changes its design shape, the tire template 3 can be easily replaced with a tire template 3 of a new shape by disassembling the tire template 3, and the gap between the tire template 3 and the inner side of the lower tooling template 8 allows the metal plate to be processed to not contact the inner side of the lower tooling template 8. Therefore, the tire template 3 with a changed shape can be easily replaced, and then the new tire template 3 is used to extrude the metal plate to be processed into the gap between the lower tooling template 8 and the tire template 3, so that the metal plate to be processed is processed into the shape of the new tire template 3, which meets the processing requirements of tire templates 3 of different shapes, has a wider range of applications, and saves usage costs compared to the traditional replacement of the entire tooling mold.

[0024] How it works

[0025] It should be noted that the utility model is a wing lower skin tooling. When in use, first, the second lifting ring 15 is lifted to drive the tooling lower template 8 to drive the second fixing frame 16 to drive the second top plate 17, and the second top plate 17 is placed in the working position, and then the handle 6 is pulled to drive the second connecting rod 5 to be pulled out from the tire template 3, and then the first connecting rod 4 on the tire template 3 is pulled out, and then the tire template 3 is placed on the inner side of the side mold frame 7, and the first connecting rod 4 is passed through one side of the side mold frame 7 and then inserted back into the tire template 3. Similarly, the handle 6 is pulled to drive the second connecting rod 5 to pass the second connecting rod 5 through the other side of the side mold frame 7 and then inserted back into the tire template 3, and the tire template 3 is installed on the inner side of the side mold frame 7, and then the top of the side mold frame 7 is installed to the bottom of the tooling upper template 1, and then the positioning rod 10 is inserted into the positioning hole on one side of the tire template 3 through the slide groove opened at the bottom of the tooling upper template 1 to fix the position of the tire template 3 in the side mold frame 7, and then the tire template 3 to be loaded The metal plate is placed on the tooling lower template 8, and then the tooling upper template 1 is hoisted and aligned with the positioning pin 11 through the first lifting ring 12, and the positioning pin 11 is used to position and pass through the tooling upper template 1, and then the first top plate 14 is pushed by the hydraulic equipment to push the first fixed frame 13, and the first fixed frame 13 pushes the tooling upper template 1 to push the side mold frame 7, and the side mold frame 7 drives the tire template 3 by driving the first connecting rod 4 and the second connecting rod 5, and presses the tire template 3 to be processed on the tooling lower template 8. The top of the tooling lower template 8 is connected to the side mold frame 7, and the bottom of the tooling lower template 8 is supported by the second fixed frame 16 and the second top plate 17. Since a gap is set between the bottom of the tire template 3 and the top of the tooling lower template 8, the tire template 3 extrude the metal plate to be processed into the tooling lower template 8 to form the shape of the tire template 3. After the pressing is completed, the processed skin is ejected by pushing the ejection block 9 from the bottom of the tooling lower template 8 to realize the manufacturing of the skin.

[0026] After the tire template 3 has been used for a period of time, the tire template 3 presses a certain amount of skin and becomes worn. The positioning rod 10 is pulled out of one side of the tire template 3, and then the handle 6 is pulled to drive the second connecting rod 5 to separate from the tire template 3. The first connecting rod 4 is pulled to separate from the tire template 3 to disassemble the worn tire template 3 and replace it with a new tire template 3. After the new tire template 3 is installed back into the side mold frame 7 through the first connecting rod 4 and the second connecting rod 5, the positioning rod 10 is inserted into one side of the tire template 3 again to fix the position of the tire template 3, thereby achieving the purpose of convenient disassembly and replacement of the tire template 3.

[0027] When the tire template 3 extrude and shapes the skin into the lower tooling template 8, since the skin is sandwiched between the lower tooling template 8 and the side mold frame 7, the tire template 3 squeezes and pushes the skin to protrude into the gap between the lower tooling template 8 and the tire template 3, and the protruding part of the skin does not contact the inner side of the lower tooling template 8 and is formed due to the shape of the tire template 3. After replacing the tire template 3 with a different shape, the skin is still squeezed and pushed by the tire template 3 to protrude into the gap between the lower tooling template 8 and the tire template 3, thereby achieving the purpose of adapting to the skin processing of tire templates 3 with different shapes.

[0028] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
