[0047] Embodiment 1
[0048] Please refer to Figures 1 to 6 , Embodiment 1 of the present utility model is: a cable bending machine for bending cables, wherein the cables include but are not limited to coaxial cables.
[0049] The cable bending machine includes a frame 1, a base 2, a first driving member 3, a second driving member 4, a third driving member 5, a first rotating clamping arm 61, a first reset member 62, a second rotating clamping arm 71 and a second reset member 74; the base 2 is arranged on the frame 1, and a fixed clamping block 21 is arranged on the base 2; the first driving member 3 is arranged on the frame 1, and the output end of the first driving member is connected to a moving clamping block 31, and the moving clamping block 31 is arranged corresponding to the fixed clamping block 21; the second driving member 4 is arranged on the frame 1, and the output end of the second driving member is connected to a first pushing block 41; the third driving member 5 is arranged on the frame 1, and the output end of the third driving member is connected to The second push block 51; the first rotating clamping arm 61 is rotatably disposed on the first push block 41, the first reset member 62 contacts the first rotating clamping arm 61 and the first push block 41 respectively to drive the first rotating clamping arm 61 to reset, and the first push block 41 is provided with a stop block 42 for stopping the first rotating clamping arm 61; the second rotating clamping arm 71 is rotatably disposed on the base 2, and the second rotating clamping arm 71 is used to cooperate with the first rotating clamping arm 61 to clamp a partial area of the cable; the second reset member 74 contacts the second rotating clamping arm 71 and the base 2 respectively to drive the first rotating clamping arm 61 to reset;
[0050] When bending the cable, the first driving member 3 drives the movable clamping block 31 to approach the fixed clamping block 21 so that a partial area of the cable is clamped and fixed between the fixed clamping block 21 and the movable clamping block 31; the second driving member 4 drives the first pushing block 41 to drive the first rotating clamping arm 61 to approach the second rotating clamping arm 71 so that a partial area of the cable is clamped and fixed between the first rotating clamping arm 61 and the second rotating clamping arm 71; the third driving member 5 drives the second pushing block 51 to push the first rotating clamping arm 61 to drive the second rotating clamping arm 71 to rotate to bend the cable.
[0051] Preferably, when the first rotating clamping arm 61 and the second rotating clamping arm 71 contact and clamp the cable simultaneously, the rotation center axis of the first rotating clamping arm 61 and the rotation center axis of the second rotating clamping arm 71 are coaxial.
[0052] The base 2 and the frame 1 can be either a separate structure or an integrated structure, and can be selected and set according to actual manufacturing conditions.
[0053] In order to facilitate the staff to place the cables accurately on the base 2, the base 2 is provided with a cable groove 22 for positioning the cables.
[0054] Optionally, the base 2 is provided with an escape groove 23 for evading the end of the cable, and the escape groove 23 is located on the side of the second rotating clamping arm 71 away from the fixed clamping block 21. When the bending position on the cable is far away from the end of the cable, in order to avoid interference between the end of the cable and the base 2, it is necessary to provide the escape groove 23 on the base 2.
[0055] Specifically, the first rotating clamping arm 61 is rotationally connected to the first pushing block 41 through the first shaft member 63, the first reset member 62 is a torsion spring, the first reset member 62 is sleeved on the first shaft member 63, and the first reset member 62 is respectively connected to the first pushing block 41 and the first rotating clamping arm 61; the second rotating clamping arm 71 is rotationally connected to the base 2 through the second shaft member 72, the second reset member 74 is a torsion spring, the second reset member 74 is sleeved on the second shaft member 72, and the second reset member 74 is respectively connected to the base 2 and the second rotating clamping arm 71.
[0056] In this embodiment, the base 2 is provided with an arc limit groove 24, and the bottom of the second rotating clamping arm 71 is provided with a limit block 73 extending into the arc limit groove 24, and the center of the arc limit groove 24 is located on the central axis of the second shaft member 72.
[0057] The first driving member 3 is a cylinder, an electric push rod, a hydraulic push rod or a motor screw assembly; similarly, the second driving member 4 is a cylinder, an electric push rod, a hydraulic push rod or a motor screw assembly; the third driving member 5 is a cylinder, an electric push rod, a hydraulic push rod or a motor screw assembly. In this embodiment, the first driving member 3, the second driving member 4 and the third driving member 5 are cylinders respectively.
[0058] The frame 1 is provided with an electrically connected control switch 8 and a control panel. The control panel is housed in an electric control box 9. The control panel is electrically connected to the first driving member 3, the second driving member 4 and the third driving member 5 respectively.
[0059] The frame 1 or the base 2 is also provided with a holding mechanism, which is used to hold the second rotating clamping arm 71, so as to prevent the second rotating clamping arm 71 from being unexpectedly reset under the action of the second reset member 74. Specifically, after the cable is bent, when the staff removes the bent cable from the cable bending machine, the first push block 41, the first rotating clamping arm 61 and the movable clamping block 31 are reset respectively. Since the position of the second rotating clamping arm 71 is held by the holding mechanism, the second rotating clamping arm 71 will not be reset directly, and can only be reset after the holding mechanism releases the hold. Therefore, the staff has enough time to remove the bent cable. The holding mechanism includes common holding components such as a pin shaft or an electromagnet. When the holding mechanism includes a latch, the base 2 has a latch hole, and the second rotating clamping arm 71 is provided with a hole corresponding to the latch hole. The pin shaft is inserted into the hole through the latch hole manually or driven by a driving member, thereby preventing the second rotating clamping arm 71 from resetting under the drive of the second resetting member 74. When the holding mechanism includes an electromagnet, the second rotating clamping arm 71 is provided with a magnet or patch that cooperates with the electromagnet.
[0060] The working process of the cable bending machine is briefly described as follows: when bending the cable, the staff first places the coaxial line into the cable groove 22, and then presses the control switch 8, and the control panel sequentially controls the first driving member 3, the second driving member 4 and the third driving member 5 to act. When the first driving member 3 is working, the movable clamping block 31 is driven by the first driving member 3 to approach the fixed clamping block 21 to cooperate with the fixed clamping block 21 to clamp and fix the cable. When the second driving member 4 is working, the first pushing block 41 drives the first rotating clamping arm 61 to approach the second rotating clamping arm 71 until the first rotating clamping arm 61 and the second rotating clamping arm 71 clamp the cable. At this time, the first shaft 63 and the second shaft The second driving member 72 is coaxial. When the third driving member 5 is working, the second pushing block 51 contacts the first rotating clamping arm 61 and pushes the first rotating clamping arm 61 to rotate. At the same time, the first rotating clamping arm 61 pushes a partial area of the cable to drive the second rotating clamping arm 71 to rotate together, so that the cable is bent to achieve the bending of the cable. After that, the holding mechanism works to lock the second rotating clamping arm 71. Then, the third driving member 5, the second driving member 4 and the first driving member 3 are reset in turn. After the staff removes the bent cable, the holding mechanism releases the lock on the second rotating clamping arm 71, and the second rotating clamping arm 71 is reset under the drive of the second resetting member 74.
[0061] The above are only optional embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present invention.
