Detailed Description of the Preferred Embodiments

[0020] The technical solutions of the utility model will be further specifically described below through embodiments and in conjunction with the drawings.

[0021] Embodiment: AsFigures 1-5 As shown in the figure, a split beam riveting tooling structure includes a tooling component 2, which is composed of an upper template 6 and a lower template 12. A central positioning disc 10 is arranged between the upper template 6 and the lower template 12. A pair of upper beam punching sheets 5 and lower beam punching sheets 11 are respectively arranged at the front and rear ends of the central positioning disc 10. A pair of reinforcing ribs 20 inserted into the upper beam punching sheets 5 are arranged between the upper beam punching sheets 5. Two pairs of reinforcing ribs 20 inserted into the lower beam punching sheets 11 are arranged between the lower beam punching sheets 11. Oil cylinder fixing plates 3 are arranged on both sides of the front end and the rear end of the floating positioning plate 16. A propulsion oil cylinder 1 is arranged on the oil cylinder fixing plate 3. Reinforcing rib fixing inserts 4 are arranged between the propulsion oil cylinder 1 and the reinforcing ribs 20. A pressing plate 9 is arranged between the central positioning disc 10 and the upper template 6. Riveting joints 17 for corresponding riveting with the reinforcing ribs 20 are arranged between the upper beam punching sheets 5 and the pressing plate 9, and between the lower beam punching sheets 11 and the pressing plate 9. An upper backing plate 7 is arranged between the upper template 6 and the pressing plate 9. Ten pressure springs 8 penetrating through the upper backing plate 7 are arranged between the upper template 6 and the pressing plate 9. A floating positioning plate 16 is arranged between the central positioning disc 10 and the lower template 12. A lower backing plate 15 is arranged between the lower template 12 and the floating positioning plate 16. Ten floating springs 14 penetrating through the lower backing plate 15 are arranged between the lower template 12 and the floating positioning plate 16. Upper beam positioning seats 19 fixed to the floating positioning plate 16 by screw connections are arranged on both sides of the upper beam punching sheets 5. Lower beam positioning seats 18 fixed to the floating positioning plate 16 by screw connections are arranged at the rear end of the lower beam punching sheets 11. Guide posts 13 penetrating through the pressing plate 9 and the floating positioning plate 16 are arranged on the side of the upper beam positioning seat 19 and the lower beam positioning seat 18. The guide posts 13 are located between the upper template 6 and the lower template 12.

[0022] Working principle: Pre-assemble 2 upper support beam punching sheets 5 and 2 stiffeners 20, and at the same time pre-assemble 2 lower support beam punching sheets 11 and 4 stiffeners 20. Then place them respectively into the slots between the front and rear ends of the central positioning disk 10 and the lower support beam positioning seat 18 and the upper support beam positioning seat 19. Driven by the equipment, the propulsion oil cylinder 1 pushes the stiffener fixing insert block 4 forward to make full contact with the stiffener 20, playing a role in protecting the stiffener and ensuring that the stiffener will not turn over during the riveting process. Subsequently, press down the upper template 6 so that the pressure plate 9 contacts the upper support beam punching sheet 5 and the lower support beam punching sheet 11, and the tooling clamping component. Then the hydraulic press starts to pressurize, and the floating positioning plate 16 moves down to closely adhere to the lower backing plate 15. At this time, the riveting head 17 makes full contact with the stiffener 20 and rivets the head teeth shape, and fully combines with the upper support beam punching sheet 5 and the lower support beam punching sheet 11 on the side of the floating positioning plate 16. Continue to pressurize, and the riveting head 17 makes full contact with the stiffener 20 and rivets the head teeth shape, and fully combines with the upper support beam punching sheet 5 and the lower support beam punching sheet 11 on the side of the pressure plate 9 that is adhered to. At this time, start to hold the pressure for 3 seconds, and then the equipment starts to return. After the pressure plate 9 disengages from the parts, the floating spring 14 pushes the floating positioning plate 16 to push the product away to the zero position, and the propulsion oil cylinder 1 drives the stiffener fixing insert block 4 to reset. At this time, the parts can be taken out, and the product riveting is completed.

[0023] In summary, the split support beam riveting tooling structure has the characteristics of compact structure, convenient operation and good running stability. The riveting is a cold working process, which avoids the problems of product thermal deformation and stress concentration during the welding process. Due to the split support beam design, the upper and lower support beams that originally needed to be welded or riveted in two times can now be riveted in one time.
