[0025] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0026] Embodiment 1

[0027] like Figure 1-4 As shown, a disposable titanium clamp rod heat shrink tooling includes a heating coil 2 and an annular air knife body 3. The heating coil 2 and the annular air knife body 3 are sealed and fixedly connected. The interiors of the heating coil 2 and the annular air knife body 3 are provided with cavities penetrating through the heating coil 2 and the annular air knife body 3 and are interconnected. The cavity is suitable for inserting a heat shrink tube 1, and the interior of the heat shrink tube 1 is suitable for placing the clamp rod body 5. The annular air knife body 3 is suitable for introducing air into the interior of the heating coil 2 to quickly heat the heat shrink tube 1.

[0028] In this embodiment, if Figure 2 As shown, a fixing component is provided between the heating coil 2 and the heat shrink tube 1. The fixing component may be a locking cover, which is connected to the heating coil 2. The locking cover, the heat shrink tube 1 and the clamp rod body 5 are locked by a locking bolt, while ensuring that the airflow can pass through the heating coil normally. This is different from the manual heat shrinking of the heat shrink gun in the prior art, reduces inconsistency and instability, and reduces labor costs.

[0029] In this embodiment, if Figure 1-4 As shown, a power line 4 is arranged outside the heating coil 2 .

[0030] Embodiment 2

[0031] like Figure 1-4 As shown, this embodiment further includes the following structure on the basis of the first embodiment: the annular wind knife body 3 is provided with a compressed air inlet 8, a guide channel and an annular Coanda wall 11, the Coanda wall 11 is a partial cavity wall of the cavity, the guide channel guides the compressed air entering from the compressed air inlet 8 to the Coanda wall 11, and the Coanda wall 11 is suitable for spraying the compressed air guided thereto to the right side of the annular wind knife body 3 and forming a low-pressure area 12 on the left side of the annular wind knife body 3.

[0032] like Figure 1-4 As shown, the guide channel includes an annular cavity 10 connected to the compressed air inlet 8 and an annular nozzle 9 connected to the annular cavity, and the annular nozzle 9 is connected to the Coanda wall 11.

[0033] The annular wind knife body 3 includes an annular wind knife lower cover plate 6 and an annular wind knife upper cover plate 7 which are connected; specifically, the annular wind knife lower cover plate 6 and the annular wind knife upper cover plate 7 can be connected by screws.

[0034] Specifically, Figure 3-4 As shown, the compressed air inlet 8 is arranged inside the lower cover plate 6 of the annular wind knife.

[0035] Specifically, Figure 3-4 As shown, the annular cavity 10 is arranged in the lower cover plate 6 of the annular wind knife.

[0036] like Figure 3-4 As shown, the nozzle 9 is specifically formed between the annular wind knife lower cover plate 6 and the annular wind knife upper cover plate 7. The nozzle 9 is communicated with the annular cavity 10 and is suitable for guiding the passing airflow.

[0037] like Figure 3-4 As shown, the Coanda wall 11 is in a tapered shape that gradually becomes larger from right to left along the axial direction.

[0038] like Figure 3 As shown, the low-pressure area 12 can draw external air into the interior of the heating coil 2 to form an annular hot air flow 13.

[0039] The working principle of this embodiment is as follows:

[0040] When in use, the disposable titanium clamp rod that needs to be heat shrunk is placed inside the heat shrink tube 1, and the heat shrink tube 1 is fixed inside the heating coil 2 through a fixing component and passes through the heating coil 2 and the annular air knife body 3. It should be noted that the heat shrink tube 1 will not completely block the opening of the internal cavity of the heating coil 2, leaving a gap for exhausting gas.

[0041] During the heat shrink process, air is first introduced from the compressed air inlet 8, and the air flows into the inside of the annular cavity 10 to form an air ring. Then the air flow passes through the annular nozzle 9 at a high speed, and is discharged at a high speed along the Coanda wall 11 on the lower cover plate 6 of the annular wind knife, and is ejected from the right side of the heating coil 2 along the side wall of the air ring at the angle of the Coanda wall 11, thereby generating a low-pressure area 12 in the center of the air ring. The negative pressure of the low-pressure area 12 will force a large amount of surrounding air to be sucked into the interior of the heating coil 2 along the center position.

[0042] At this time, the heating coil 2 is energized to heat the inhaled airflow. When the inhaled air leaves the air ring and leaves from the right side of the heating coil 2, a 360° conical circular hot airflow 13 is generated. The uniform and powerful circular hot airflow 13 can continuously and stably blow toward the heat shrink tube 1 on the right side of the heating coil 2, and heat the heat shrink tube 1 while discharging the gas inside the heat shrink tube 1, uniformly shrinking the disposable titanium clamp rod of the shaft parts by 360°, thereby improving work efficiency, ensuring the tightness and airtightness of the product while ensuring the beautiful appearance of the parts.

[0043] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
