[0024] like Figures 1-4 The tooling for forming a French-made helicopter equipment duct assembly includes: a base 1 with an L-shaped cross section, and a template 2 set on one side plate of the base 1 for bending and fixing the duct 8 into an irregular shape. The template 2 has a groove that matches the shape of the bent duct 8, and multiple quick-release clamps 3 set on the template 2 for fixing the duct 8.

[0025] The quick-release pipe clamp 3 is arranged along the groove direction.

[0026] Working principle:

[0027] First, the conduit 8 before bending is placed on the template 2, the template 2 has a groove consistent with the shape of the conduit 8 after forming, the conduit 8 is gradually bent along the groove of the template 2, wherein the conduit 8 is 5A02 aluminum alloy, and the size of the conduit 8 is 16mm*1mm. Because the shape of the groove limits the final shape of the conduit 8, the conduit 8 will be gradually bent and fixed into the required special-shaped part in the process of applying external force (such as manual or with the help of some matching bending tool) to make the conduit 8 fit the groove. The groove plays a precise shape guiding and restraining role, so that the conduit 8 can be accurately bent into the shape required by the helicopter equipment conduit assembly. After bending, lock the multiple quick-release pipe clamps 3 on the template 2 to fix the bent conduit 8, and when the conduit 8 is completely bent to the end along the groove, the transformation from the initial straight pipe state to the special-shaped part is completed. At this time, all quick-release pipe clamps 3 are in the clamping state, and the conduit 8 is firmly fixed in the formed position to ensure that the shape of the conduit 8 is stable and unchanged.

[0028] Further comprising: a flexible layer arranged on the groove and the U-shaped notch. By adopting the technical scheme, the conduit 8 frequently contacts and rubs with the groove and the U-shaped notch during the bending and forming of the conduit 8. The flexible layer can effectively prevent the surface of the conduit 8 from being scratched. At the same time, the arrangement of the flexible layer can increase the friction between the conduit 8 and the groove and the quick-release pipe clamp 3, and reduce the shape deviation caused by insecure fixing.

[0029] In the above technical scheme, the one side plate of the base 1 is provided with a mounting joint 5 matched with the threaded joint 4 at one end of the conduit 8, and the other side plate of the base 1 is provided with a mounting interface 6 matched with the threaded joint 4 at the other end of the conduit 8; wherein the threaded joint 4 at one end of the conduit 8 is connected with the mounting joint 5 through internal threads, and the threaded joint 4 at the other end of the conduit 8 is connected with the mounting interface 6 through external threads. By adopting the technical scheme, in actual operation, the threaded joints 4 are respectively installed to the mounting joint 5 and the mounting interface 6 on the two side plates of the base 1, and are screwed tightly through threaded connection, wherein the threaded joints 4 at the two ends of the conduit 8 are external threaded joints at one end and internal threaded joints at the other end, the threaded joint 4 comprises a connecting pipe welded with the conduit 8, a connecting head sleeved on the connecting pipe, and an external thread arranged on the connecting head and connected with the mounting interface, and a boss larger than the rear end size of the connecting surface of the connecting head is arranged around the surface of the connecting pipe. The threaded joints 4 are welded to the two ends of the conduit 8 to form a conduit assembly.

[0030] In the above technical solution, the quick release pipe clamp 3 comprises: a clamping piece 31 rotatably arranged on one side of the groove, the clamping piece 31 being provided with a U-shaped notch on the contact surface with the conduit 8, a fixed base 32 arranged on the other side of the groove, and a connecting rod 33 rotatably arranged on the fixed base 32 and matched with the clamping part; wherein the clamping part is provided with a notch matching the size of the connecting rod 33, and the connecting rod 33 is threadedly connected with a wing nut 34. With this technical solution, the clamping part is rotatably arranged on one side of the groove, and the clamping piece 31 is provided with a U-shaped notch on the contact surface with the conduit 8, which is matched with the connecting rod 33 rotatably arranged on the fixed base 32 on the other side of the groove, forming the structure of the clamp. This rotatable connection allows the clamping part and the connecting rod 33 to rotate relatively flexibly, making it easy for the operator to easily put or take out the conduit 8. When the conduit 8 needs to be fixed, the operator only needs to rotate the clamping part to make it close to the connecting rod 33, and make the connecting rod 33 extend into the notch in the clamping part, so as to quickly realize the preliminary clamping and positioning of the conduit 8. The operation is very convenient and meets the needs of quick disassembly. The wing nut 34 is threadedly connected to the connecting rod 33. The wing nut 34 can be easily twisted by hand without the help of tools due to its unique shape. After the conduit 8 is preliminarily clamped, the wing nut 34 can be tightened to further enhance the clamping force on the conduit 8, ensuring that the conduit 8 is stably fixed in the groove of the mold plate 2 during the bending and forming process. When the conduit 8 needs to be disassembled, the wing nut 34 is loosened in the opposite direction to quickly release the clamping state of the conduit 8, and the conduit 8 can be taken out by rotating the clamping part again. The whole process is simple and efficient, greatly improving the convenience and efficiency of the tool.

[0031] The wing nut 34 is threadedly connected to the connecting rod 33, and the tightening degree can accurately control the size of the clamping force. During the forming process of the conduit 8, different conduit 8 materials, pipe diameters and bending degrees have different requirements for the clamping force. For example, for a conduit 8 with a harder material or a larger bending angle, a larger clamping force may be needed to ensure the stable fixation of the conduit 8 in the groove of the mold plate 2. Using the wing nut 34, the operator can finely adjust the clamping force by rotating the wing nut 34 according to the actual situation, so as to achieve the best fixing effect. The buckle locking method usually fixes it by the engagement of the buckle, and the clamping force is relatively fixed, which is difficult to adjust accurately, and may not meet the accuracy requirements of different conduit 8 fixing needs.

[0032] In the above technical solution, further comprising: a gasket 7 sleeved on the connecting rod 33, the gasket 7 is located on the contact surface of the wing nut 34 and the clamping piece 31. With this technical solution, when the wing nut 34 is tightened to clamp the conduit 8, the gasket 7 can play a role in uniformly dispersing the pressure. Because if there is no gasket 7, the wing nut 34 directly contacts the clamping piece 31, and during the application of the clamping force, the pressure will be concentrated near the contact point due to the relatively small contact area of the wing nut 34 and the clamping piece 31. The gasket 7 can increase the contact area, so that the clamping force can be more evenly distributed on the clamping piece 31, thereby avoiding deformation or damage of the clamping piece 31 due to excessive local pressure, and ensuring the stability and reliability of the clamping piece 31 clamping the conduit 8. At the same time, the presence of the gasket 7 can also prevent local wear caused by direct friction between the wing nut 34 and the clamping piece 31.

[0033] Although the embodiments of the present application have been disclosed as above, it is not limited to the application listed in the specification and the embodiments, and can be fully applied to various fields suitable for the present application. For those skilled in the art, other modifications can be easily realized, and therefore the present application is not limited to specific details and the figures shown and described herein.
