[0040] In this embodiment:

[0041] Reference Figure 1-Figure 3 As shown, a preferred embodiment of the present invention is provided.

[0042] The cable protection tube processing equipment of this embodiment includes a support plate 1 and a control device 14. The two ends of the support plate 1 are equipped with clamping plates 2 through spring shaft connecting pieces 24. The clamping plates 2 are used to fix the cable protection tube 5.

[0043] A support 131 is installed on the support plate 1, and the support 131 is used to apply a force to the cable protection tube 5;

[0044] The other end of the support plate 1 is also connected to force arms 3 on both sides through a rotating shaft, and a connecting steel cable 4 is connected between the ends of the two force arms 3. The outer side of the connecting steel cable 4 is provided with an expansion bag 43 placed inside the cable protection tube 5. The expansion bag 43 is filled with expandable silicone particles. An electric heating rod 431 is also installed inside the expansion bag 43. The electric heating rod 431 is used to heat the expandable silicone particles to support the inner wall of the cable protection tube 5, and cooperate with the support 131 to complete the bending operation.

[0045] The expansion bag 43 is provided with an electric heating rod 431, which is used to heat the expansion silica gel particles in the expansion bag 43, so that the expansion silica gel particles can fill the inner side of the bending part of the cable protection tube 5, and conduct the heat to the bending part of the cable protection tube 5, so that it can be better bent by external force;

[0046] Meanwhile, the control device 14 includes a power supply and a PLC, which is electrically connected to each electrical component via a PLC of model S7-400, uses the power supply to supply power to each electrical component, and realizes automatic bending operation on the cable protection tube 5 .

[0047] In the attached Figure 1 In the embodiment, a force motor 11 is installed at the end of the support plate 1, and the output shaft of the force motor 11 is connected to a guide rod 12 extending to the inside of the support plate 1, and the external thread of the guide rod 12 is connected to a guide seat 13, and the support 131 is fixed by the guide seat 13. The guide rod 12 is driven to rotate by the force motor 11, thereby pushing the guide seat 13 connected to its external thread to slide, so that the support 131 installed on the guide seat 13 cooperates with the expansion bag 43 to complete the bending operation of the cable protection tube 5.

[0048] In the attached Figure 2-Figure 3 In the embodiment, the clamping plate 2 includes a first sleeve 21, the inner bearing at the end of the first sleeve 21 is connected to a clamping position adjusting rod 22, the outer side of the clamping position adjusting rod 22 is threadedly connected to a first telescopic rod 23, the end of the first telescopic rod 23 passes through and extends to the outer side of the end of the first sleeve 21, and is fixed to the spring shaft connecting piece 24, the support plate 1 is located at the outer side of the connection with the spring shaft connecting piece 24 and is marked with an angle scale 25, and a limit baffle 26 is also provided on the support plate 1, under the action of the limit baffle 26, it is used to limit the angle between the clamping plate 2 and the support plate 1 to prevent the cable protection tube 5 from being heated and deformed in reverse, and at the same time, the bending angle of the cable protection tube 5 can be quickly obtained through the angle scale 25 to improve the bending accuracy.

[0049] It is worth noting that a clamping piece 27 is also installed on the clamping plate 2. Four clamping rods 271 are connected to the bearings on the clamping plate 2. The clamping piece 27 is connected to the four clamping rods 271 through threaded cooperation, and the ends of the four clamping rods 271 are connected through belt transmission. By rotating one of the clamping rods 271, the other three clamping rods 271 can be driven to rotate synchronously, driving the clamping piece 27 connected to the external thread to rise and fall, so as to be able to clamp and release the cable protection tube 5.

[0050] Furthermore, by rotating the clamping position adjusting rod 22, the first telescopic rod 23 connected to its external thread is driven to extend and retract. A thread groove corresponding to the thread on the surface of the clamping position adjusting rod 22 is provided on the inner wall of the first telescopic rod 23, thereby adjusting the distance between the clamp 27 and the support plate 1, thereby changing the relative position of the clamp 27 clamping the cable protection tube 5 to adapt to the bending requirements of cable protection tubes 5 of different lengths.

[0051] In the attached Figure 4 In the figure, the end of the force arm 3 is connected to a turntable 31 via a rotating shaft, a connecting cylinder 32 is provided on one side of the turntable 31, the connecting steel cable 4 passes through the connecting cylinder 32, and a locking rod 33 is also connected to one side of the connecting cylinder 32 via a thread, and the connecting steel cable 4 inserted into the connecting cylinder 32 is locked or released by rotating the locking rod 33, so that the connecting steel cable 4 can always remain in a taut state during the bending process of the cable protection tube 5.

[0052] Refer to the attached Figure 2 and attached Figure 5 As shown, both ends of the expansion bag 43 are respectively provided with a storage bin 42 and a second sleeve 41, the storage bin 42 is used to store the expanded silica gel particles, the inner side bearing of the end of the second sleeve 41 is connected to a rotating rod 411, the outer thread of the rotating rod 411 is connected to a second telescopic rod 412, the inner wall of the second telescopic rod 412 is provided with a thread groove corresponding to the thread on the surface of the rotating rod 411, the end of the second telescopic rod 412 penetrates and extends to the interior of the storage bin 42, and the end of the second telescopic rod 412 is connected to the outer side of the second telescopic rod 412. The part is also provided with a push plate 413. The end of the connecting steel cable 4 is connected to the end of the rotating rod 411. The rotating rod 411 can be driven to rotate by rotating the connecting steel cable 4, and then the rotating rod 411 is used to push the second telescopic rod 412 to extend and retract, so that the push plate 413 at the telescopic end of the second telescopic rod 412 pushes the expanded silica gel particles in the material storage bin 42 into the expansion bag 43, so that the expanded silica gel particles are pressed against the inside of the cable protection tube 5, and the temperature is provided for the cable protection tube 5, so as to avoid the cable protection tube 5 from breaking or deforming when being bent.

[0053] The four sides of the material storage bin 42 are connected to the support rod 421 through a spring shaft, and the ends of the support rod 421 are installed with a pulley 422. It is worth noting that this allows the support rod 421 to be stretched outward when the expansion bag 43 is inserted into and the cable protection tube 5 is withdrawn, so that the pulley 422 can be pressed against the inner wall of the cable protection tube 5, thereby improving the smoothness of insertion and withdrawal.

[0054] The cable protection tube bending equipment uses a support plate 1 as the main frame, and an angle-adjustable clamping plate 2 is installed through spring shaft connecting pieces 24 on both sides. The clamping plate 2 includes a first sleeve 21, a clamping position adjustment rod 22, a first telescopic rod 23, and a clamping rod 271 driven by four belts to drive a clamping piece 27, so as to achieve the clamping and position adjustment of the cable protection tube 5;

The inner wall of the cable protection tube 5 is supported by heating and expanding silicone particles. The material bin 42 and the rotating rod 411 in the second sleeve 41 drive the push plate 413 to transport the particles, and the support rod 421 and the pulley 422 are used to improve the smoothness of the expansion bag 43 passing through the tube; the control device 14 links various components through the S7-400 PLC, combines the angle scale 25 and the limit baffle 26 to accurately control the bending angle, and finally realizes the automatic thermoplastic bending of the cable protection tube 5, effectively avoiding deformation and breakage.
