[0032] Example 4

[0033] like Figures 1 to 10 As shown, especially with Figure 1 Taking the view direction shown as an example, the directions of other views can be referenced. Figure 1 Based on Embodiments 1, 2, and 3, a device for heat-shrinking and shaping S-shaped wire harness tubing is provided. The bottom ends of the moving platform 6 are slidably mounted on the auxiliary slide rail 12 and the main slide rail 2 via platform sliders 5.

The platform moving screw 3 is threadedly connected to a screw nut 4 below the moving platform 6, and the screw nut 4 is fixedly connected to the moving platform 6. The platform moving screw 3 is connected to the output end of the platform servo motor 1.

[0034] Based on the above embodiments, this application will further describe and explain the technical features involved, the functional role of the technical features in the technical solution, and the working process of this application, so as to help those skilled in the art to fully understand the technical solution described in this application and be able to reproduce it.

[0035] In this application, the mobile platform 6 is provided with two processing stations, which can be driven by the platform servo motor 1, the platform main slide rail 2, the platform moving lead screw 3, the lead screw nut 4, the platform slider 5, and the platform auxiliary slide rail 12 to realize the alternation of the two stations.

[0036] The working process of this application is as follows: After the wire harness 17 is fitted with a thermoplastic insulating protective sleeve, one end of the wire harness 17 is snapped and fixed to the cold air box 24 of the wire harness fixing base B20, and the other end of the wire harness 17 is snapped and fixed to the wire harness fixing base A16. The wire harness fixing base A16 and the wire harness fixing base B20 (or the cold air box 24) are connected by an insulating protective sleeve. After placement, the lifting cylinder 9 starts to work. The extension end of the lifting cylinder 9 drives the hot air heating tube 10 to move upward through the connecting plate. During the upward movement of the hot air heating tube 10, it will drive the U-shaped hot air gun 11 connected to it to move upward. The U-shaped hot air gun 11 extends out from the hot air gun extension hole 22 and stops after the U-shaped chamber of the U-shaped hot air gun 11 accommodates the wire harness 17 and the thermoplastic insulating protective sleeve.

[0037] The hot air heating tube 10 and the U-shaped hot air gun 11 heat the wire harness 17 and the thermoplastic insulating protective sleeve located in the U-shaped chamber with hot air, so that the thermoplastic insulating protective sleeve covers the wire harness 17. After the thermoplasticization is completed, the lifting cylinder 9 drives the hot air heating tube 10 to move downward, so that the U-shaped hot air gun 11 moves downward from the hot air gun extension hole 22 until it is detached from the wire harness 17.

[0038] High-pressure gas is introduced into the pre-cooling duct 23 and passes through the cold air box 24 toward the cold air outlet of the wire harness 17 to cool the end of the wire harness 17 located in the cold air box 24. After cooling is completed, the high-pressure gas is stopped being introduced into the pre-cooling duct 23.

[0039] At this time, the cooling cylinder 13 starts working, driving the cooling and shaping air box 15 to move along the wire harness fixing seat A16 until it is aligned with the guide frame 18. After the cooling and shaping air box 15 is aligned with the guide frame 18, it stops moving along the wire harness fixing seat A16. The guide frame 18 is connected to the telescopic end of the guide cylinder 19 and moves closer to and fits against the cooling and shaping air box 15 under the action of the guide cylinder 19. The other end of the wire harness 17 covered with a thermoplastic insulating protective sleeve is located between the cooling and shaping air box 15 and the wire harness 17, and its vertical movement is limited by the cooling and shaping air box 15 and the wire harness 17. Specifically, the wire harness 17 is located in the internal space formed by the notch chamber where the S-shaped surface 31 is located and the guide opening 33.

[0040] After the above process is completed, the shaping cylinder 7 starts to work. The extension end of the shaping cylinder 7 drives the wire harness fixing seat B20 to move along the fixing seat slide rail 21. Since the other end of the wire harness 17 is limited by the cooling and shaping air box 15 and the guide frame 18, the movement of the shaping cylinder 7 and the wire harness fixing seat B20 will cause the cold air box 24 to move the end of the wire harness 17 located at that position. The other end of the wire harness 17 that has not been temporarily cooled will gradually adhere to the S-shaped surface 31. Under the action of the compressed air outlet 30 on the S-shaped surface 31, the cooling of this end is achieved.

[0041] After cooling is complete, all structures are reset, and wire harness 17 can be removed from wire harness fixing seat A16 and wire harness fixing seat B20. When the moving platform 6 is working in dual positions, after the platform servo motor 1 drives the moving platform 6 to slide along the platform main slide rail 2 and platform auxiliary slide rail 12 via the platform slider 5 to the other position through the platform moving screw 3 and screw nut 4, the wire harness 17 can be removed.

[0042] Finally, although the technical solutions in this application are described by way of embodiments, new embodiments obtained by rearranging and combining the embodiments of this application under the conditions of the prior art that those skilled in the art have mastered should be understood to still be within the protection scope of this application and be protected by this application.
