Description

Technical Field

[0001] The utility model relates to the technical field of electric tools, in particular to a power line diameter variable bender. Background Art

[0002] During the installation and maintenance of power lines, the bending operation of power lines is an indispensable part. The bending radius of power lines is directly related to their transmission efficiency and safety. Therefore, high requirements are placed on the accuracy and flexibility of power line bending. Traditional power line bending methods often rely on manual operations, which are not only inefficient but also difficult to ensure the accuracy and consistency of bending.

[0003] At present, although there are some power line bending tools on the market, most of them cannot conveniently adjust the bending radius during the bending process, resulting in poor flexibility and adaptability of power line bending. In order to meet the power line bending needs in different scenarios, it is particularly important to develop a power line bending tool that can conveniently adjust the bending radius and improve bending accuracy and efficiency.

[0007] The power line is inserted into the threading frame and the bending frame, and when the bending frame rotates, the power line can be attached to the side wall of the truncated cone block, thereby bending the power line;

[0008] When the truncated cone block moves up and down, the vertical position of the electric power line attached to the side wall of the truncated cone block changes, so that the bending radius of the electric power line changes.

[0009] Furthermore, the support mechanism comprises a workbench, the bottom of the workbench is connected to a support leg, and the upper surface of the workbench is connected to a bracket;

[0010] The threading frame and the bending frame are both connected to the workbench;

[0012] Furthermore, a first threaded rod is threadedly connected to the bending frame, a pressure plate is connected to the bottom end of the first threaded rod, the pressure plate is located inside the bending frame, and when the first threaded rod is rotated, the pressure plate can press the power line tightly inside the bending frame.

When the second threaded rod rotates, the truncated cone block can move vertically.

[0015] Furthermore, the bracket is connected with a limit plate, the truncated table block is connected with a slide bar, and the limit plate is provided with an inclined slide groove matched with the slide bar;

[0016] The slope of the inclined slide groove is equal to the taper of the truncated cone block, so that when the truncated cone block moves, the distance between the side wall of the truncated cone block and the threading rack remains unchanged.

[0017] Furthermore, a swivel is rotatably connected to the side wall of the truncated cone block, and the sliding rod is fixedly connected to the outer wall of the swivel.

[0018] Furthermore, the number of the sliding rods and the number of the limiting plates are both two, and the two sliding rods and the two limiting plates are symmetrically arranged on both sides of the bracket.

[0020] A circular ring is rotatably connected to the side wall of the positioning plate, a sliding frame is connected to the circular ring, the bending frame is slidably connected to the sliding frame, and the positioning plate is synchronized with the lateral movement of the truncated cone block, so that the bending frame can always swing with the truncated cone block as the center of the circle.

[0021] Furthermore, a third threaded rod is connected to the top of the cylindrical rod, and the third threaded rod is threadedly connected to the bottom of the truncated cone block;

[0022] When the third threaded rod is separated from the truncated cone block, the bent electric power line can be separated from the truncated cone block.

[0025] The power lines are inserted into the threading frame, and the threading frame is fixedly connected to the supporting mechanism to ensure the transmission and fixation of the power lines during the bending process. The bending frame is rotatably connected to the supporting mechanism. When the bending frame rotates, it can apply bending force to the power lines so that the power lines are attached to the side walls of the truncated cone block. The vertical position of the side walls of the truncated cone block determines the radius of the bending of the power lines. The truncated cone block in the adjustment mechanism is set to move up and down, so that the truncated cone block can move up and down on the supporting mechanism. When the truncated cone block moves up and down, the vertical position of the power line attached to the side walls of the truncated cone block will change accordingly, thereby changing the bending radius of the power line. Whether a small radius bending or a large radius bending is required, it can be achieved by adjusting the position of the truncated cone block, thereby adapting to power line bending operations with different needs.

[0037] Example

[0038] like Figure 1-Figure 5As shown, a power line diameter variable bender includes a support mechanism 100 and a bending mechanism 200, the bending mechanism 200 includes a threading frame 210 and a bending frame 220, the threading frame 210 is fixedly connected to the support mechanism 100, and the bending frame 220 is rotatably connected to the support mechanism 100, and an adjustment mechanism 300 is provided on the support mechanism 100, and the adjustment mechanism 300 includes a truncated cone block 330 which is movable up and down and is arranged on the support mechanism 100; the power line is inserted into the threading frame 210 and the bending frame 220, and when the bending frame 220 rotates, the power line can be attached to the side wall of the truncated cone block 330, thereby bending the power line; when the truncated cone block 330 moves up and down, the vertical position of the power line attached to the side wall of the truncated cone block 330 changes, thereby changing the bending radius of the power line.

[0039] The working mechanism of the variable diameter power line bender provided in this embodiment is as follows:

[0040] The power line is inserted into the threading frame 210, and the threading frame 210 is fixedly connected to the support mechanism 100 to ensure the transmission and fixation of the power line during the bending process. The bending frame 220 is rotatably connected to the support mechanism 100. When the bending frame 220 rotates, it can apply a bending force to the power line so that the power line is attached to the side wall of the truncated cone block 330. The vertical position of the side wall of the truncated cone block 330 determines the radius of the bending of the power line. The truncated cone block 330 in the adjustment mechanism 300 is arranged to move up and down, so that the truncated cone block 330 can move up and down on the support mechanism 100. When the truncated cone block 330 moves up and down, the vertical position of the power line attached to the side wall of the truncated cone block 330 will change accordingly, thereby changing the bending radius of the power line. Whether a small radius bending or a large radius bending is required, it can be achieved by adjusting the position of the truncated cone block 330, thereby adapting to power line bending operations with different requirements.

[0041] Regarding the structure of the support mechanism 100, specifically:

[0042] The support mechanism 100 includes a workbench 110 , the bottom of the workbench 110 is connected to a support leg 130 , the upper surface of the workbench 110 is connected to a bracket 120 ; the threading frame 210 and the bending frame 220 are both connected to the workbench 110 ; and the truncated table block 330 is connected to the bracket 120 .

[0043] The setting of the workbench 110 supports the entire device, the support legs 130 support the workbench 110, the setting of the bracket 120 provides support for the installation of the truncated table block 330, and the threading frame 210 and the bending frame 220 are connected to the workbench 110, so that the workbench 110 provides positioning for the threading frame 210 and the bending frame 220.

[0044] Regarding how to fix the power line in the bending frame 220, specifically:

[0045] A first threaded rod 240 is threadedly connected to the bending frame 220 , and a pressing plate 241 is connected to the bottom end of the first threaded rod 240 . The pressing plate 241 is located inside the bending frame 220 , and when the first threaded rod 240 is rotated, the pressing plate 241 can press the power line tightly inside the bending frame 220 .

[0046] The power line to be bent is passed through the threading rack 210. The cross-section of the threading rack 210 is L-shaped, and the L-shaped opening faces the truncated cone block 330, so that the power line can be easily bent. After passing through the threading rack 210, the power line is inserted into the bending rack 220. Tightening the first threaded rod 240 can make the pressure plate 241 press the power line, so that the end of the power line is fixed in the bending rack 220, so that the power line will not be separated from the bending rack 220 during subsequent bending, so that the power line can be stably bent.

[0047] Among the optional methods of this embodiment, the more preferred ones are:

[0048] A handle 230 is connected to the end of the bending frame 220 .

[0049] The handle 230 is provided for the convenience of the operator to hold. When the power line is fixed, the operator holds the handle 230 and turns the bending frame 220 to bend the power line.

[0050] Among the optional methods of this embodiment, the more preferred ones are:

[0051] The bracket 120 is slidably connected with a slider 310 , the slider 310 is threadedly connected with a second threaded rod 320 , and the truncated cone block 330 is connected to the bottom end of the second threaded rod 320 . When the second threaded rod 320 rotates, the truncated cone block 330 can move vertically.

[0052] The setting of the slider 310 allows the second threaded rod 320 to be installed and fixed, and the slider 310 does not move in the vertical direction. The truncated cone block 330 is connected to the bottom of the second threaded rod 320, so that when the second threaded rod 320 is rotated, the vertical position of the truncated cone block 330 can be changed, thereby changing the bending radius of the power line.

[0053] How to ensure that the distance between the truncated cone block 330 and the electric line remains unchanged when the bending radius changes, specifically:

[0054] A limit plate 360 ​​is connected to the bracket 120, a slide rod 351 is connected to the truncated cone block 330, and an inclined slide groove 361 cooperating with the slide rod 351 is provided on the limit plate 360; the inclination of the inclined slide groove 361 is equal to the taper of the truncated cone block 330, so that when the truncated cone block 330 moves, the distance between the side wall of the truncated cone block 330 and the threading rack 210 remains unchanged.

[0055] When the truncated cone block 330 moves up and down, the slide rod 351 connected to the truncated cone block 330 can slide in the inclined groove 361 on the limiting plate 360, and since the slope of the inclined groove 361 is equal to the taper of the truncated cone block 330, the truncated cone block 330 will also move laterally while moving downward, thereby keeping the distance between the side wall of the truncated cone block 330 and the threading rack 210 unchanged.

[0056] Among the optional methods of this embodiment, the more preferred ones are:

[0057] A rotating ring 350 is rotatably connected to the side wall of the truncated cone block 330 , and a sliding rod 351 is fixedly connected to the outer wall of the rotating ring 350 .

[0058] The setting of the rotating ring 350 ensures that the slide bar 351 will not rotate synchronously when the truncated block 330 rotates following the second threaded rod 320, thereby ensuring that the slide bar 351 slides stably in the inclined slide groove 361 and also ensuring that the movement of the truncated block 330 is not interfered with and stuck.

[0059] Among the optional methods of this embodiment, the more preferred ones are:

[0060] The number of the sliding rods 351 and the number of the limiting plates 360 are both two, and the two sliding rods 351 and the two limiting plates 360 are symmetrically arranged on both sides of the bracket 120 .

[0061] The arrangement of the two sliding rods 351 and the two limiting plates 360 enables the forces on both sides of the truncated cone block 330 to be balanced when the truncated cone block 330 moves, thereby ensuring the stable movement of the truncated cone block 330 .

[0062] Regarding how to ensure that the rotation center of the bending frame 220 is maintained at the axial position of the truncated cone block 330, specifically:

[0063] A cylindrical rod 340 is connected to the bottom of the truncated cone block 330, a positioning plate 270 is slidably connected to the workbench 110, and the cylindrical rod 340 is inserted into the middle of the positioning plate 270; a ring 260 is rotatably connected to the side wall of the positioning plate 270, a sliding frame 250 is connected to the ring 260, and the bending frame 220 is slidably connected to the sliding frame 250. The positioning plate 270 is synchronized with the lateral movement of the truncated cone block 330, so that the bending frame 220 can always swing with the truncated cone block 330 as the center of the circle.

[0064] Since the truncated cone block 330 will also move laterally when it moves downward, the center position of the truncated cone block 330 will change, and the cylindrical rod 340 at the lower part of the truncated cone block 330 is inserted into the positioning plate 270, so that the vertical movement of the truncated cone block 330 will not be restricted, and the lateral movement of the truncated cone block 330 can drive the positioning plate 270 to move laterally synchronously, and the positioning plate 270 can drive the bending frame 220 to move synchronously through the ring 260 and the sliding frame 250 when it moves laterally, thereby ensuring that the rotation center of the bending frame 220 can always fall on the axis of the truncated cone block 330 to ensure the bending effect of the power line. When adjusting the bending radius of the power line, first insert the power line into the threading frame 210 and the bending frame 220, and then adjust the position of the truncated cone block 330, so as to ensure that the insertion of the power line is easier.

[0065] Regarding how to take out the bent power line, specifically:

[0066] The top of the cylindrical rod 340 is connected to a third threaded rod 341 , which is threadedly connected to the bottom of the truncated cone block 330 ; when the third threaded rod 341 is separated from the truncated cone block 330 , the bent power lines can be separated from the truncated cone block 330 .

[0067] After the power line is bent, the first threaded rod 240 is rotated to release the fixation between the bending frame 220 and the power line, and then the cylindrical rod 340 is rotated to make the third threaded rod 341 disengage from the truncated cone block 330, so that the bent power line can be taken out of the device at this time, completing the bending operation of the power line.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of each embodiment of the utility model.
