[0061] The riveting die for the fixing plate of a large torque UAV according to an embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0062] Reference Figures 1 to 6 As shown, the high-torque UAV fixing plate riveting die provided according to the embodiment of the utility model includes a lower die assembly 10, a pre-riveting assembly 20 and a pressure riveting assembly 30.

[0063] The lower die assembly 10 is disposed on a punching machine, and a plurality of die holes 131 are evenly spaced apart on the lower die assembly 10 . The plurality of die holes 131 are used to install the parts to be riveted and the rivets 133 .

[0064] The lower mold assembly 10 is mainly used to fix parts and rivets 133. A plurality of mold holes 131 are arranged thereon. The plurality of mold holes 131 are arranged side by side. A part and a rivet 133 can be assembled in each mold hole 131 at the same time. In this way, a plurality of parts and a plurality of rivets can be assembled in a plurality of mold holes 131 at the same time.

[0065] The pre-riveting assembly 20 includes a pre-riveting upper template 21, a pre-riveting upper clamping plate 22 and a plurality of pre-riveting punches 23. The pre-riveting upper template 21 is detachably arranged on a punching machine device. The pre-riveting upper clamping plate 22 is arranged at the bottom of the pre-riveting upper template 21. The plurality of pre-riveting punches 23 are all arranged on the pre-riveting upper template 21 and pass through the pre-riveting upper clamping plate 22 to pre-press the parts and rivets in the plurality of die holes 131. The lower end of the pre-riveting punch 23 is a conical structure.

[0066] The pre-riveting assembly 20 is mainly used for pre-riveting parts and rivets in multiple die holes 131, that is, to preliminarily rivet the parts and rivets. It specifically includes a pre-riveting upper template 21, a pre-riveting upper clamping plate 22 and multiple pre-riveting punches 23. The pre-riveting upper template 21 can be assembled on the punching machine equipment and located above the lower die assembly 10, and then the pre-riveting upper clamping plate 22 and multiple pre-riveting punches 23 are fixed above the lower die assembly 10. In this way, during pre-riveting, the punching machine equipment can drive multiple pre-riveting punches 23 to simultaneously press the parts and rivets in multiple die holes 131, and the lower end of the pre-riveting punch 23 is a conical structure. Then, when the pre-riveting punch 23 presses the parts and rivets, the pressure on the parts and rivets is more concentrated, and accordingly, the pressure on the parts and rivets is greater, so that the rivets can be better pressed into the parts, thereby better making the parts and rivets preliminarily riveted.

[0067] The riveting assembly 30 includes an upper riveting template 31, an upper riveting clamp 32 and a plurality of riveting punches 33. The upper riveting template 31 is detachably arranged on a punching machine. The upper riveting clamp 32 is arranged at the bottom of the upper riveting template 31. The plurality of riveting punches 33 are all arranged on the upper riveting template 31 and pass through the upper riveting clamp 32 to rivet the parts and rivets 133 in the plurality of die holes 131. The lower end of the pre-riveting punch 23 is a flat structure.

[0068] The riveting assembly 30 is mainly used to completely rivet the pre-riveted parts and rivets in multiple die holes 131, that is, to rivet the parts and rivets in place to form a finished product. It specifically includes an upper riveting template 31, an upper riveting clamp 32 and multiple riveting punches 33. The upper riveting template 31 can be assembled on a punching machine and located above the lower die assembly 10, and then the upper riveting clamp 32 and multiple riveting punches 33 are fixed above the lower die assembly 10. In this way, during riveting, the punching machine can drive multiple riveting punches 33 to simultaneously press the parts and rivets in multiple die holes 131, and the lower end of the riveting punch 33 is a flat structure. Then, when the riveting punch 33 presses the parts and rivets, the pressure on the parts and rivets is more uniform, and accordingly, the pressure on the parts and rivets is more uniform, so that the rivets can be better pressed into the parts, thereby better completing the riveting of the parts and rivets.

[0069] More specifically, when in use, the pre-rivet component 20 is first installed on the punching equipment, and then the parts and rivets are respectively installed in the die holes 131 on the lower die assembly 10. After the installation is completed, the punching equipment can be turned on to move the pre-rivet component 20 downward by a predetermined distance. During this process, the multiple pre-rivet punches 23 on the pre-rivet component 20 can respectively exert a certain pressure on the parts and products in the multiple die holes 131, thereby making the parts and rivets initially riveted; further, the punching equipment drives the pre-rivet component 20 to reset upward, the staff removes the pre-rivet component 20 from the punching equipment, and then replaces the upper riveting component 30, and the punching equipment drives the riveting component 30 downward by a certain distance. During this process, the multiple riveting punches 33 can exert a certain pressure on the pre-riveted parts and rivets in the multiple die holes 131, thereby making the parts and rivets completely riveted together, so that the parts and rivets can be processed into finished products.

[0070] According to the riveting die for the fixing plate of a large torque UAV provided by the utility model, when riveting parts and rivets 133, pre-riveting can be performed first, and then pressure riveting can be performed to improve the riveting quality of parts and rivets and the qualified rate of products. At the same time, multiple products can be processed at one time, thereby improving processing efficiency and facilitating popularization and use.

[0071] Advantageously, in one embodiment of the present invention, the lower mold assembly 10 comprises:

[0072] A lower die base 11, wherein the lower die base 11 is connected to a punch press device;

[0073] A lower pad 12, wherein the lower pad 12 is disposed on the lower die base 11;

[0074] The lower template 13 is arranged on the lower pad 12, and the plurality of mold holes 131 are arranged in the lower template 13. The plurality of mold holes 131 are each provided with a press rivet insert 132, and the plurality of press rivet inserts 132 are used to support the parts.

[0075] Preferably, the rivet insert 132 is provided with a through hole 1321 , and the rivet is passed through the through hole 1321 .

[0076] The lower die base 11 is fixed on the punching machine, and then the lower pad 12 and the lower template 13 are installed on the punching machine. The lower template 13 is provided with a plurality of die holes 131, and a rivet insert 132 is provided in each die hole 131. Therefore, when the part is installed in the die hole 131, the part can be abutted against the upper surface of the rivet insert 132, and the rivet insert 132 is provided with a through hole 1321. Then, the rivet can be inserted into the through hole 1321 after passing through the part. In this way, during the pre-riveting and rivet pressing stages, the rivet can move downward along the through hole 1321 until it is finally riveted together with the part.

[0077] Advantageously, in another embodiment of the present invention, a plurality of support assemblies 14 are further included, each of the plurality of support assemblies 14 includes a press-riveted top material block 142 and an elastic support member 141;

[0078] The pressure riveting top material block 142 is movably disposed in the through hole 1321 to push the rivet upward;

[0079] The elastic support member 141 is disposed on the lower die base 11 and connected to the pressure riveting top material block 142 , and is used to eject the riveted parts and the rivet 133 from the die hole 131 through the pressure riveting top material block 142 .

[0080] Preferably, the elastic support member 141 includes a spring member and a support rod;

[0081] The lower end of the spring member is connected to the lower die base 11, and the upper end is connected to the support rod;

[0082] The support rod is inserted into the pressure riveting insert 132 and connected to the pressure riveting top material block 142 .

[0083] The number of support components 14 is equal to the number of die holes 131, and the rivets can be inserted into the rivet inserts 132 in the die holes 131 to support the rivets. Specifically, the rivet top material block 142 of the support component 14 is movably inserted into the through hole 1321 on the rivet insert 132, and can move up and down along the through hole 1321, and the elastic support member 141 of the support component 14 is installed on the lower die base 11 and connected to the rivet top material block 142. In this way, when riveting parts and rivets, the parts are supported by the rivet inserts 132, and the rivets are inserted into the parts and abut against the rivet top material block 142. When the rivet component 30 gradually presses the rivet down to rivet with the parts, the rivet can be pressed downward to rivet. The push block 142 then presses the elastic support member 141 through the pressure riveting push block 142, so that the elastic support member 141 is compressed to generate elastic force. Therefore, after the parts and the rivets are riveted, in the process of the pressure riveting assembly 30 moving upward and resetting, the compressed elastic support member 141 can generate an upward thrust on the rivet, thereby lifting the riveted product on the pressure riveting insert 132 until it is ejected into the die hole 131. In this way, it is convenient for the staff to take out the riveted products and re-assemble new parts and rivets in the die hole 131.

[0084] Advantageously, in some embodiments of the present invention, a plurality of pre-riveting guide fixing members 24 are provided on the pre-riveting upper clamping plate 22 , and the plurality of pre-riveting guide fixing members 24 are vertically opposite to the plurality of die holes 131 , and are used to press and fix the parts on the press rivet inserts 132 .

[0085] On the one hand, the pre-riveting guide fixing member 24 can position the pre-riveting assembly 20 and the lower die assembly 10 to ensure that the pre-riveting punch 23 on the pre-riveting assembly 20 can be aligned with the die hole 131, thereby pre-riveting the parts and rivets in the die hole 131; on the other hand, the pre-riveting guide fixing member 24 can also press and fix the parts to prevent the parts from shifting during the pre-riveting process and affecting the pressure riveting effect.

[0086] Preferably, a riveting guide fixing member 34 is also provided in the riveting upper template to position the riveting die set and the lower die assembly for accurate riveting.

[0087] Advantageously, in some other embodiments of the present invention, the number of the mold holes 131 is nine.

[0088] In this way, a part and a rivet can be installed in each of the nine die holes 131. In this way, during pre-riveting and press riveting, the pre-riveting component 20 and the press riveting component 30 can be used to pre-rivet and press rivet the parts and rivets in the nine die holes 131 at the same time. Accordingly, nine products can be processed at one time, thereby greatly improving the processing efficiency.

[0089] Of course, in other embodiments, the number of die holes 131 can be set to be more or less according to usage requirements, and the number of pre-riveting punches 23 and press-riveting punches 33 can be adjusted accordingly.
