[0047] As shown in Figure 7 and Figure 8It is also necessary to understand that the saddle bottom plate mold 5 also includes a carrier plate two 507, and the carrier plate two 507 is provided with a bottom plate assembly mold 509 on the side facing the hot branding device 7, and the bottom plate assembly mold 509 is used to install the saddle bottom plate.

In use, the saddle bottom plate is stably attached to the bottom plate assembly mold 509 by the suction force generated by the suction cup port 592, which can effectively ensure the stability during movement.

[0048] Looking back Figure 7 Similarly, the saddle bottom plate mold 5 also includes a balance plate two 501, and the balance plate two 501 is provided with a cylinder two 502 on the side away from the bottom plate assembly mold 509. The movement of the balance plate two 501 in the vertical direction can be directly controlled through the cylinder two 502. Similarly, a connecting plate two 503 is fixed on the side away from the cylinder two 502. The connecting plate two 503 and the carrier plate two 507 are also connected and fixed by a plurality of fixed rods two 506, and the carrier plate two 507 and the fixed rod two 506 are connected and fixed by bolts, which facilitates the installation, disassembly or replacement of the bottom plate assembly mold 509. Among them, the middle rod two 505 is also connected between the middle part of the carrier plate two 507 and the connecting plate two 503 to improve the stability.

[0049] Looking back Figure 1 It should be understood that the saddle hot welding device also includes a rack, which provides a stable carrier and working environment for the device. The rack includes a base 1 and a top plate 3, and the base 1 and the top plate 3 are connected and fixed by a frame rod 2. Among them, the slide liner one 408 and the slide liner two 504 are respectively arranged on the balance plate one 401 and the balance plate two 501 corresponding to the frame rod 2 to reduce friction. The saddle surface mold 4 and the saddle bottom plate mold 5 move in the vertical direction relying on the rack after being controlled by the cylinder one 402 and the cylinder two 502.

[0050] It should be understood that the two sides of the rack are provided with rails 6, and the two rails 6 are fixed at the frame rod 2 by fixed hoops 8. The two rails 6 are parallelly arranged between each other and the ground. The hot branding device 7 is arranged on the rails 6, and moves to the between the saddle bottom plate mold 5 and the saddle surface mold 4 through the rails 6. The end of the rail 6 away from the rack is in contact with the ground through the supporting leg 9 to keep stable and balanced.

[0051] As Figure 8 shown, in order to ensure the smooth implementation of the above embodiment, it is necessary to understand that the hot branding device 7 includes a shelf plate 701, both ends of the shelf plate 701 are fixed with a side lap 705, the side lap 705 supports the hot branding device 7 between the two tracks 6, and an electric drive wheel is arranged at the side lap 705 to facilitate movement. The hot branding device 7 and the track 6 can be assembled to form a linear sliding table to control the movement of the hot branding device 7, so as to transfer the hot branding device 7.

[0052] As Figure 9 shown, the side of the shelf plate 701 facing the saddle surface mold 4 and the saddle bottom plate mold 5 is respectively provided with a hot branding plate one 703 and a hot branding plate two 704, and the side of the hot branding plate one 703 and the hot branding plate two 704 facing the shelf plate 701 is fixed with a heat conducting plate 702. The heat conducting plate 702 is connected with the shelf plate 701 through a plurality of support columns, so as to leave a gap between the heat conducting plate 702 and the shelf plate 701, so as to dissipate heat in a continuous working state. Among them, the hot branding plate one 703 is attached to the side surface of the saddle bottom plate B, and the hot branding plate two 704 is attached to the side surface of the saddle surface seat B.

[0053] As Figure 10 and Figure 11 shown, further to the scheme, the hot welding technology of the saddle is to heat and melt the hot branding protrusions on the saddle surface seat and the saddle bottom plate, and then press and splice the saddle surface seat and the saddle bottom plate. After cooling at the hot branding protrusions, the hot welding between the saddle surface seat and the saddle bottom plate is realized. In order to realize the above process, it is also necessary to understand that the heat conducting plate 702 includes a frame plate 10 and a cover plate 12, and the hot branding plate one 703 and the hot branding plate two 704 are fixed on the corresponding cover plate 12. It should be understood that the hot branding plate one 703 and the hot branding plate two 704 are both provided with texture fitting grooves 15 matched with the hot branding protrusions on the saddle surface seat and the saddle bottom plate, and hot branding wires 16 are arranged in the texture fitting grooves 15. The hot branding protrusions are directly heated by the hot branding wires 16, but it should be understood that the height of the hot branding wires 16 is lower than the top surface height of the hot branding plate one 703 and the hot branding plate two 704, and the width of the texture fitting groove 15 is also greater than the width of the hot branding protrusion. In this way, the hot branding area can be limited to the hot branding protrusion, the heat dissipation is reduced, and the saddle deformation problem caused by heat dissipation is reduced.

[0054] As Figure 11As shown, it is understood that the cover plate 12 can slide along the inner wall of the frame plate 10, and the bottom of the frame plate 10 is provided with a plurality of threaded ends 13, and the cover plate 12 is provided with screws 11 that pass through the cover plate 12 and are screwed with the threaded ends 13, and the screws 11 are sleeved with springs 14 at the inner part of the frame plate 10, that is, when the cover plate 12 is pressed and moves towards the frame plate 10, the cover plate 12 will automatically reset after the pressing is removed, and the hot branding wire 16 is fixed on the frame plate 10 through a plurality of supports 17, that is, the height of the hot branding wire 16 does not change.

[0055] In this case, taking the saddle bottom plate mold 5 as an example, after the saddle bottom plate is installed on the saddle bottom plate mold 5, the height of the saddle bottom plate mold 5 is controlled to make the saddle bottom plate mold 5 close to the hot branding plate one 703 and contact, and then continue to press towards the hot branding plate one 703, at this time, the hot branding plate one 703 will move with the cover plate 12, and the hot branding convex part of the saddle bottom plate will be in contact with the hot branding wire 16, so as to realize the heating of the hot branding convex part.

[0056] It is understood that a press switch is arranged at the bottom wall of the frame plate 10 to control whether the hot branding wire 16 is heated, when the cover plate 12 moves and contacts the press switch, the hot branding wire 16 is heated, and when the cover plate 12 leaves the press switch, the hot branding wire 16 stops heating, which can effectively avoid the heat dissipation caused by the continuous heating of the hot branding wire 16, and avoid the generation of quality problems in the heating process.

[0057] In summary, based on the above device, we propose a use method of saddle hot welding, which includes the following steps:

[0058] Step one: place the saddle surface seat on the placing area of the saddle surface combined mold 407, and ensure that the middle bone module 471 and the thigh pad module 472 are completely attached to the side surface of the saddle surface seat B.

[0063] Step six: keep the pressure for 1-3 seconds, and the hot branding filament 16 partially melts the hot branding protrusion to form a molten layer.

[0064] Step seven: after heating, the air cylinder one 402 and the air cylinder two 502 are temporarily retracted by 10-30 cm, and the hot branding device 7 moves out of the working position along the track 6.

[0065] Step eight: drive the air cylinder one 402 and the air cylinder two 502 to pressurize again, so that the molten hot branding protrusion of the saddle face seat tightly engages with the saddle base plate. Keep the pressure for 5-10 seconds until the molten part cools and solidifies to form a firm welding point.

[0066] Regarding the above embodiment, it also needs to be supplemented that the Chinese patent with the authorization announcement number CN218967076U discloses a kind of intermediate plate between saddle face seat and saddle base plate, which is welded by intermediate plate and saddle face seat and saddle base plate, which can also be applied to the device, including the following steps:

[0070] Step four: start the air cylinder one 402 to drive the saddle face die 4 to move towards the hot branding device 7.

[0071] Step five: when the hot branding protrusion of the intermediate plate contacts the hot branding plate two 704, continue to press until the cover plate 12 compresses the spring 14, triggering the press switch to start the hot branding filament 16.

[0072] Step six: keep the pressure for 1-3 seconds, and the hot branding filament 16 partially melts the hot branding protrusion to form a molten layer.

[0073] Step seven: after heating, the air cylinder one 402 is temporarily retracted by 10-30 cm, and the hot branding device 7 moves out of the working position along the track 6.

[0074] Step eight: drive the air cylinder one 402 and the air cylinder two 502 to make the molten hot branding protrusion of the intermediate plate tightly engage with the saddle base plate, or separately drive the air cylinder one 402 to make the molten hot branding protrusion of the intermediate plate tightly engage with the saddle base plate.

[0075] Step nine: start the air cylinder one 402 to reset the saddle face die 4.

[0076] Step ten: move the hot branding device 7 to the center position between the saddle surface mold 4 and the saddle bottom plate mold 5 along the track 6.

[0077] Step eleven: drive the cylinder two 502 to move the saddle bottom plate mold 5 to the hot branding device 7.

[0078] Step twelve: when the hot branding convex part of the intermediate plate contacts the hot branding plate one 703, continue to press until the cover plate 12 compresses the spring 14, and the press-on switch triggers the hot branding wire 16.

[0079] Step thirteen: keep the pressure for 1-3 seconds, and the hot branding wire 16 partially melts the hot branding convex part to form a molten layer.

[0080] Step fourteen: after the heating is completed, the cylinder two 502 is temporarily retracted by 10-30 cm, and the hot branding device 7 is horizontally moved out of the working position along the track 6.
