[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0036] When laying cables in vacuum containers, mineral insulated cables are mostly used; mineral insulated cables are covered with a metal outer layer, and have the characteristics of small outer diameter, high hardness, and high length accuracy requirements of mineral insulated cables. At present, mineral insulated cables can only be bent once by hand or with auxiliary tools, and multiple checks are required after bending to meet the requirements for laying mineral insulated cables in vacuum containers. When bending cables by hand or with auxiliary tools, the bending force cannot be controlled, which may damage the cables.

[0037] Since the operating space in the vacuum container is limited, most existing devices cannot perform cable bending operations in the limited space, and the bending precision is low, which often cannot meet the requirements of cable laying.

[0038] In view of this, an embodiment of the present invention provides a cable bending device, which can effectively improve the efficiency of cable bending. Through cylinder control, the cable can be continuously bent and the cable bending angle can be standardized and consistent, and the cable bending force can be controlled according to the cylinder.

[0039] Combine the following Figure 1 to Figure 2 , describing an embodiment of the present invention.

[0040] According to an embodiment of the present invention, a cable bending device is provided, comprising: a main body 100; a pressure unit, arranged on the main body 100, for applying pressure to a cable 200; a support unit, arranged on the main body 100, arranged opposite to the pressure unit, for supporting the cable 200; the pressure unit comprises a first pressure assembly 110, a second pressure assembly 120, and a third pressure assembly 130; the first pressure assembly 110 comprises a first cylinder 111 and a first pressure head 112, and the second pressure assembly 120 comprises a second cylinder 121 and a second pressure head 130. The pressure head 122, the third pressure assembly 130 includes a third cylinder 131 and a third pressure head 132; at least one cable 200 is supported on the support unit, and the first cylinder 111, the second cylinder 121 and the third cylinder 131 respectively control the first pressure head 112, the second pressure head 122 and the third pressure head 132 to pre-press the cable 200, and the second cylinder 121 and the third cylinder 131 continue to move to drive the first cylinder 111 to move, and the first pressure head 112 automatically presses the cable 200 to bend the cable 200. Among them, the first cylinder 111 can be a slide cylinder, the second cylinder 121 and the third cylinder 131 are main force cylinders, and the second cylinder 121 and the third cylinder 131 apply force to drive the movement of the first cylinder 111.

[0041] The cable bending device provided in the embodiment of the present invention controls the movements of the first pressing head 112, the second pressing head 122 and the third pressing head 132 respectively through the first cylinder 111, the second cylinder 121 and the third cylinder 131, so that the three pressing heads cooperate with the supporting unit, thereby automatically pressing at least one cable 200, which can effectively improve the efficiency of cable bending. Through cylinder control, the cable can be bent continuously and the standardization and consistency of the cable bending angle can be maintained, and the cable bending force can be controlled according to the cylinder.

[0042] In other embodiments, two cables 200 may be supported on a supporting unit, and the first cylinder 111, the second cylinder 121, and the third cylinder 131 respectively control the first pressing head 112, the second pressing head 122, and the third pressing head 132 to pre-press the two cables 200 at the same time, and the second cylinder 121 and the third cylinder 131 continue to move to drive the first cylinder 111 to move, and the first pressing head 112 automatically presses the two cables 200 at the same time to simultaneously bend the two cables 200. When the cable bending device provided by the embodiment of the present invention is used to bend multiple cables at the same time, not only can the cables 200 be bent continuously, but also the bending angles of the two cables 200 can be standardized and consistent.

[0043] In one embodiment, the first pressure assembly 110, the second pressure assembly 120 and the third pressure assembly 130 are arranged on the same support frame 170, so that the first pressure head 112, the second pressure head 122 and the third pressure head 132 are in the same horizontal direction. In this embodiment, the first pressure assembly 110, the second pressure assembly 120 and the third pressure assembly 130 can be arranged on the same support frame 170 by welding. When the first pressure assembly 110, the second pressure assembly 120 and the third pressure assembly 130 move, the three pressure assemblies can be driven to move synchronously by the support frame 170, so that the movement of the three pressure assemblies is consistent. When the three pressure assemblies are welded to the support frame 170, it is also necessary to ensure that the first pressure head 112, the second pressure head 122 and the third pressure head 132 are in the same horizontal direction, so as to ensure that the cable 200 is subjected to uniform pressure during the bending process, reduce the situation of local excessive force, and facilitate the bending of the cable.

[0044] Further, the second pressure assembly 120 and the third pressure assembly 130 are connected to the main body 100 through a bracket. The specific connection method can be welding, and the second pressure assembly 120 and the third pressure assembly 130 can be more firmly fixed to the main body 100 by welding. Since the first pressure assembly 110, the second pressure assembly 120 and the third pressure assembly 130 are welded on the same support frame 170, when the second cylinder 121 and the third cylinder 131 move, the support frame 170 can be driven to move, thereby synchronously driving the first cylinder 111 to move, and the first pressure head 112, the second pressure head 122 and the third pressure head 132 can be kept in consistent movement.

[0045] In one embodiment, a first elastic member 123 is provided between the second cylinder 121 and the second pressure head 122; a second elastic member 133 is provided between the third cylinder 131 and the third pressure head 132; the first elastic member 123 and the second elastic member 133 are used to adjust the pressure applied by the pressure unit to the cable 200. In this embodiment, the first elastic member 123 and the second elastic member 133 can both be springs; the pressure provided by the cable bending device is between 0-300kg, and the pressure provided by the cable bending device can be adjusted by replacing the models of the first elastic member 123 and the second elastic member 133, so that the bending degree of the cable can be controlled, so as to better bend the cable according to practical needs.

[0046] In one embodiment, the first pressing head 112, the second pressing head 122 and the third pressing head 132 are detachably connected to the first cylinder 111, the second cylinder 121 and the third cylinder 131, respectively. In this embodiment, the first pressing head 112, the second pressing head 122 and the third pressing head 132 can be detachably connected to the first cylinder 111, the second cylinder 121 and the third cylinder 131, respectively, by bolts. In the actual cable bending process, different usage scenarios may be encountered. By replacing the pressing head on the cylinder, the cable is pressed so that the pressed cable meets the bending requirements and the bent cable can adapt to various scenarios.

[0047] In one embodiment, the support unit includes at least one cable support block 140, which is arranged on the main body 100; at least one bearing assembly 150, which is arranged on the main body 100; and the bearing assembly 150 and the cable support block 140 are in the same horizontal direction. In this embodiment, the cable support block 140 is welded to the main body 100 to enhance the stability of the cable support block 140; the bearing assembly 150 is detachably connected to the main body 100 by bolts, and the bearing assembly 150 can cooperate with the first pressure head 112, the second pressure head 122 and the third pressure head 132 to meet more cable bending design requirements. By arranging the cable support block 140 and the bearing assembly 150 in the same horizontal direction, better support is provided for the cable 200, the shaking of the structure is reduced, and it is convenient for the pressure assembly to press the cable 200.

[0048] In other embodiments, two cable support blocks 140 are provided, and four bearing assemblies 150 are provided; four bearing assemblies 150 are provided between two cable support blocks 140; two bearing assemblies close to the cable support block 140 are provided below the second pressure head 122 and the third pressure head 132, respectively, and when the pressure unit is in a pre-pressed state, the second pressure head 122 and the third pressure head 132 are in contact with the bearing assemblies. By providing two cable support blocks 140 and four bearing assemblies 150 to support the cable 200, the horizontal state of the cable 200 on the support unit can be ensured, so that the weight is more evenly distributed on the support unit, and a single support point is prevented from being subjected to excessive pressure, thereby preventing the cable from being damaged when the cable is bent.

[0049] In other embodiments, the bearing assembly 150 is a U-shaped bearing assembly, including a U-shaped bearing body for support and rotation; inner and outer rings, respectively matched with the shaft and the bearing seat; rolling bodies, such as balls or rollers, for rolling between the inner and outer rings to reduce friction; a retaining frame for evenly separating the rolling bodies to prevent mutual collision; and a sealing device for preventing dust, impurities, etc. from entering the interior of the bearing. By providing a U-shaped bearing assembly, the cable can be moved better when bending the cable, so that the bending of the cable remains continuous.

[0050] In one embodiment, at least one groove is provided on the cable support block 140, and at least one groove is provided on the bearing assembly 150, for fixing the cable 200. The grooves are provided on the bearing assembly 150 and the cable support block 140 to facilitate fixing the cable 200, and to prevent the cable 200 from rolling freely on the bearing assembly 150 and the cable support block 140 when the cable 200 is bent. Further, two grooves are provided on the cable support block 140, and two grooves are provided on the bearing assembly 150; by providing two grooves, two cables can be placed on the support unit at the same time, and the two cables can be pressed at the same time, which effectively improves the bending efficiency of the cable. In other embodiments, the number of grooves on the cable support block 140 and the bearing assembly 150 can be 3, 4, etc., as long as the number of grooves on the cable support block 140 and the bearing assembly 150 matches. The specific setting of the number of grooves can be set according to the use requirements, and no specific restrictions are made here.

[0051] In one embodiment, at least one groove is provided on the first pressing head 112, the second pressing head 122 and the third pressing head 132, which matches the groove on the bearing assembly 150 and is used to fix the cable 200. Further, two grooves are provided on the first pressing head 112, the second pressing head 122 and the third pressing head 132. By matching the grooves provided on the pressing heads with the grooves on the bearing assembly 150, the cable to be bent can be completely covered, the stability of the bent cable is improved, and the bent cable is more in line with the design requirements; the two grooves can be provided to press the two cables at the same time, improving the cable bending efficiency.

[0052] In one embodiment, the groove width on the first pressing head 112, the second pressing head 122, the third pressing head 132, the cable support block 140 and the bearing assembly 150 is 5 mm, and the groove depth is 2.5 mm. Since the diameter of the mineral insulated cable is 4 mm, a 0.5 mm thick sheath is wrapped outside the mineral insulated cable, so that the total diameter of the mineral insulated cable becomes 5 mm. After the mineral insulated cable is placed on the cable support block 140 and the bearing assembly 150, when the pressure unit is in a pre-pressing state, the first pressing head 112, the second pressing head 122 and the third pressing head 132 are in contact with the cable, and the second pressing head 122 and the third pressing head 132 cooperate with the bearing assembly 150 to completely cover the mineral insulated cable, so that the cable is more firmly fixed on the support unit, providing better stability when pressing the cable.

[0053] In one embodiment, at least one operation button 160 is also provided on the main body 100 for controlling the pressure unit. Furthermore, three operation buttons 160 are provided, and the three operation buttons respectively control the pressure unit to perform pre-pressing operation, pressing operation and reset operation. In this embodiment, the three operation buttons are respectively a pre-pressing operation button, a pressing operation button and a reset operation button; after the cable 200 is placed on the support unit, when the pre-pressing operation button is pressed, the pressure unit moves to the pre-pressing state, the first pressure head 112, the second pressure head 122 and the third pressure head 132 are respectively in contact with the cable 200, and the second pressure head 122 and the third pressure head 132 cooperate with the bearing assembly 150 to pre-press the cable 200. When the pressing operation button is pressed, the second cylinder 121 and the third cylinder 131 continue to move toward the bearing assembly 150, thereby driving the first cylinder 111 to move and pressing the cable 200 through the first pressing head 112; when the pressing is completed, the reset operation button is pressed to reset the pressure unit, and the pressing is repeated after the cable 200 is moved to maintain the continuity of the pressing of the cable 200 and improve the pressing efficiency of the cable 200. By setting three operation buttons to control the pressure unit to perform pre-pressing operation, pressing operation and reset operation, the appropriate operation mode can be selected according to specific needs, the control flexibility is increased, the operation safety is improved, the occurrence of misoperation is avoided, and the convenience of cable bending operation is further improved.

[0054] In other embodiments, the main body 100, the first cylinder 111, the second cylinder 121, the third cylinder 131, the first pressure head 112, the second pressure head 122, the third pressure head 132, the cable support block 140, the bearing assembly 150, the support frame 170, the first elastic member 123 and the second elastic member 133 are all made of metal, such as stainless steel, copper, etc. The specific material used can be selected according to the needs. The material of the operating button 160 is plastic. By using plastic to make the operating button 160, the weight of the entire device can be reduced and it is more convenient to carry; using metal materials to make other parts except the operating button 160 can enhance the overall strength of the device, be able to bear greater pressure and load, have strong stability and ensure the safety of the device.

[0055] In other embodiments, the size of the second cylinder 121 is about 60mm×60mm×150mm, the third cylinder 131 and the second cylinder 121 have the same specifications, and the overall volume of the cable bending device is about 40cm×60cm×40cm, and the weight is about 20KG. A device with a small volume and a small weight is more suitable for a vacuum container with limited operating space, and is easy to carry. Among them, the size of the second cylinder 121 and the third cylinder 131 and the overall volume and weight of the device are only exemplary and are not specifically limited. They can be set according to the use requirements.
