Description

Technical Field

[0001] This utility model relates to the field of conduit cutting production technology, and in particular to a conduit cutting device. Background Technology

[0002] In the production of power and communication conduits, cutting is a crucial process to ensure the conduits are suitable for power and communication projects. To enable conduits to be better applied in power and communication construction, address the matching issue between conduits and spacing in complex terrain, and avoid material waste or shortages due to length redundancy, it is necessary to cut conduits to specified lengths according to construction requirements. Furthermore, precise cutting eliminates length errors generated during conduit production, ensuring dimensional consistency when splicing multiple conduit segments. Conduit cutting typically utilizes conduit cutting equipment. Current equipment uses a clamping module to hold the conduit in place before cutting with a cutter. However, existing equipment can easily damage the conduit surface during the clamping process, even causing irreversible deformation and affecting product quality. Utility Model Content

[0037] Reference Figures 1 to 4 This utility model provides a conduit cutting device, including a feeding assembly 100 for conveying the conduit 700 to be cut to a cutting assembly; the cutting assembly includes a support platform 200, a first fixing mechanism 300, and a cutting mechanism 500. The first fixing mechanism 300 is disposed on the discharge side of the feeding assembly 100, and the cutting mechanism 500 is disposed on the side of the first fixing mechanism 300 away from the feeding assembly 100. The support platform 200 is connected to the lower side of the first fixing mechanism 300. Specifically, the cutting mechanism 500 cooperates with the support platform 200 to cut the conduit 700, and the first fixing mechanism 300 cooperates with the support platform 200 to fix the conduit 700 to be cut, so as to avoid cutting defects caused by the shaking of the conduit 700.

[0038] The first fixing mechanism 300 includes a pressing module 320 and a limiting module 330. The limiting module 330 is connected to the pressing module 320 and is used to limit the movement of the pressing module 320. Specifically, the pressing module 320 can move vertically to press the conduit 700 downward and to release the conduit 700 upward. Specifically, the limiting module 330 can limit the downward movement of the pressing module 320. When the pressing module 320 moves downward to the maximum position, the limiting module 330 can limit the pressing module 320 to prevent it from moving further downward. At this time, the pressing module 320 presses and fixes the conduit 700, so that the conduit 700 obtains a certain elastic deformation but does not cause damage or irreversible deformation.

[0039] The first fixing mechanism 300, in conjunction with the support platform 200, can fix the conduit 700 to be cut. Then, the cutting mechanism 500, in conjunction with the support platform 200, can cut the conduit 700, preventing wobbling during cutting and improving cutting accuracy and quality. The limiting module 330 can limit the downward movement of the clamping module 320, preventing excessive pressure on the conduit 700, reducing damage to the surface of the conduit 700, and preventing irreversible deformation, thus improving the quality of the conduit 700. The limiting module 330 restricts the downward movement of the clamping module 320, limiting the deformation of the conduit 700 to a level that can elastically recover. When the clamping module 320 releases the conduit 700, the conduit 700 can automatically return to its normal size and shape, providing good protection for the conduit 700 during the cutting process.

[0040] According to some embodiments of this application, refer to Figure 3 The first fixing mechanism 300 further includes a first driving member 310. The clamping module 320 includes a clamping head 321 and a first transmission shaft 322. The clamping head 321 is connected to the lower end of the first transmission shaft 322, which is drively connected to the first driving member 310. The first driving member 310 can drive the first transmission shaft 322 to move up and down, thereby driving the clamping head 321 to move up and down. A limiting module 330 is connected to the first transmission shaft 322 and can limit the travel of the first transmission shaft 322. The first driving member 310 can be a linear motor, a double-acting cylinder, or other device capable of providing upward and downward drive. Specifically, the first fixing mechanism 300 also includes a first connecting frame 340, through which the first driving member 310 is fixedly connected to the upper part of the support platform 200. Figure 3The first connecting frame 340 has a hollow structure to allow the conduit 700 to pass through it. The limiting module 330 limits the downward travel of the first drive shaft 322, thereby limiting the downward travel of the clamping head 321 and preventing the clamping head 321 from excessively clamping the conduit 700.

[0041] As a preferred option, refer to Figure 3 The lower side of the clamping head 321 has a crescent-shaped structure. The crescent-shaped structure of the lower side of the clamping head 321 can better clamp the conduit 700 and also make the conduit 700 gather towards the center of the clamping head 321 to achieve a positioning effect.

[0042] Furthermore, the limiting module 330 is connected to the end of the first drive shaft 322 away from the support platform 200. Specifically, refer to... Figure 3 When the first drive shaft 322 moves downward to its maximum stroke, the limiting module 330 moves to the top of the first drive member 310. The first drive member 310 restricts the limiting module 330 from moving downward, thereby restricting the first drive shaft 322 from moving downward.

[0043] Furthermore, a threaded portion 323 is provided at the end of the first drive shaft 322 away from the support platform 200, and the limiting module 330 is threadedly connected to the threaded portion 323. Specifically, the limiting module 330 and the threaded portion 323 are movably connected by threads to achieve an adjustable relative position between the limiting module 330 and the first drive shaft 322. This facilitates adjusting the connection position of the limiting module 330 on the first drive shaft 322 according to the different outer diameter of the conduit 700, thereby adjusting the maximum downward stroke of the first drive shaft 322 and the pressing head 321.

[0044] Furthermore, the limiting module 330 includes a limiting sleeve 331 and a connecting nut 332. The limiting sleeve 331 and the connecting nut 332 are fixedly connected. The limiting sleeve 331 is sleeved on the outside of the first drive shaft 322, and the connecting nut 332 is threadedly connected to the threaded part 323. This allows the connecting nut 332 to be turned with a wrench or other tools to adjust the connection position of the limiting module 330 on the first drive shaft 322.

[0045] According to some embodiments of this application, refer to Figure 2 and Figure 4 The cutting mechanism 500 includes a second driving member 510, a second connecting frame 550, a second drive shaft 520, and a cutter 530. The cutter 530 is connected to the second drive shaft 520, which is drively connected to the second driving member 510. The second driving member 510 is fixedly connected to the support platform 200 via the second connecting frame 550. The second driving member 510 can be a linear motor, a double-acting cylinder, or other device capable of providing upward and downward drive. Specifically, refer to... Figure 4The second driving member 510 and the second connecting bracket 550 are disposed on the lower side of the support platform 200. The second connecting bracket 550 is fixedly connected to the second driving member 510 and the support platform 200 respectively, so that the relative position between the second driving member 510 and the support platform 200 remains unchanged. Specifically, the support platform 200 is provided with a through hole, and the second drive shaft 520 extends above the support platform 200 after passing through the through hole. The second drive shaft 520 is connected to the cutter 530 above the support platform 200. The second driving member 510 drives the second drive shaft 520 to move up and down, thereby driving the cutter 530 to move up and down, so that the cutter 530 can cut the conduit 700 downwards.

[0046] Specifically, refer to Figure 3 The second drive shaft 520 includes a main shaft portion 521, two branch shaft portions 522, and a connecting portion 523, which are connected sequentially from bottom to top. The lower end of the main shaft portion 521 is drively connected to the output end of the second drive member 510; the lower ends of the two branch shaft portions 522 are fixedly connected to the upper end of the main shaft portion 521. The two branch shaft portions 522 extend through the through holes of the support platform 200 to the top of the support platform 200, and the upper ends of the two branch shaft portions 522 are fixedly connected to both ends of the connecting portion 523 above the support platform 200.

[0047] Furthermore, the cutting mechanism 500 also includes an electric heater 540, which is attached to the cutter 530. Specifically, the electric heater 540 is a resistance heater, an electromagnetic induction heater, or other device capable of converting electrical energy into heat energy. The electric heater 540 is used to heat the cutter 530 to improve the cutting efficiency and quality of the cutter 530 on the conduit 700.

[0048] According to some embodiments of this application, refer to Figure 1 The feeding assembly 100 includes a first conveyor belt 110 and a second conveyor belt 120. The first conveyor belt 110 is disposed above the second conveyor belt 120, and a transmission channel 130 is formed between the first conveyor belt 110 and the second conveyor belt 120. Specifically, the first conveyor belt 110 and the second conveyor belt 120 rotate in opposite directions, and together they form a leftward transmission force in the transmission channel 130 to improve the feeding and transmission effect of the conduit 700 in the transmission channel 130.

[0049] Furthermore, the feeding assembly 100 also includes a ranging module 140, which is rotatably connected to the first conveyor belt 110. Specifically, the ranging module 140 includes a ranging wheel and an angle measuring instrument, with the ranging wheel rotatably connected to the first conveyor belt 110. The ranging wheel rotates with the first conveyor belt 110, and the angle measuring instrument measures the rotation distance of the outer circumference of the ranging wheel to obtain the rotation distance of the first conveyor belt 110. After the first conveyor belt 110 has rotated a specified distance, the first conveyor belt 110 and the second conveyor belt 120 are stopped. At this time, the cutting assembly is used to cut the conduit 700 to obtain a conduit 700 of a specified length.

[0050] According to some embodiments of this application, refer to Figure 1 It also includes a feeding rack 600, which is located on the side of the cutting assembly away from the feeding assembly 100. The feeding rack 600 is used to support the cut conduit 700. The feeding rack 600 is also used to support the left end of the conduit 700 when the cutting assembly cuts the conduit 700, so as to reduce the deformation of the conduit 700 due to gravity on the left end, which would affect the perpendicularity of the cut. Specifically, refer to Figure 1 The unloading rack 600 is equipped with a ramp. When the conduit 700 is cut, the subsequent conduit 700 to be cut is driven to move to the left, pushing the cut conduit 700 to the left onto the ramp. The cut conduit 700 can then slide down to the ground under the guidance of the ramp, thus completing the unloading.

[0051] It is understood that in some other embodiments, the cutting assembly further includes a second fixing mechanism 400. The first fixing mechanism 300 and the second fixing mechanism 400 are respectively disposed on the left and right sides of the cutting mechanism 500 to improve the clamping and fixing effect on the conduit 700 during cutting. Specifically, the second fixing mechanism 400 has the same structure as the first fixing mechanism 300.

[0052] Working principle: The conduit 700 to be cut is placed in the transmission channel 130. The first transmission belt 110 and the second transmission belt 120 together transport the conduit 700 towards the cutting assembly. When the ranging module 140 measures that the conduit 700 has moved a specified length, the operation of the first transmission belt 110 and the second transmission belt 120 is stopped. The first driving member 310 drives the clamping head 321 downward through the first drive shaft 322 to clamp and fix the conduit 700. When the limiting cylinder 331 of the limiting module 330 abuts against the first driving member 310, the clamping head 321 stops. The first fixing mechanism 300 and the cutting mechanism 500 are removed from the conduit 700. The second driving component 510 drives the cutting mechanism 530 downward to cut the conduit 700 through the second transmission shaft 520. After cutting, the first fixing mechanism 300 and the cutting mechanism 500 leave the conduit 700. The feeding component 100 starts to transport the subsequent conduits 700 to be cut to the cutting component. The conduits 700 that have been cut are pushed down along the unloading rack 600 to the ground by the subsequent conduits 700 to be cut.
