Description

Technical Field

[0001] This utility model relates to the field of heavy-duty tube bundle processing technology, specifically a fixed-length cutting device for heavy-duty tube bundle production. Background Technology

[0002] Heavy-duty tubing bundles are widely used in many fields such as petrochemicals, marine engineering, and power. For example, in petrochemical pipeline transportation systems, the length of the tubing bundle needs to be precisely matched to the pipeline layout and connection requirements. If the length of the tubing bundle does not meet the standards, it may lead to difficulties in pipeline connection, potential leakage hazards, and affect the safety and normal operation of the entire system. Therefore, heavy-duty tubing bundles need to be cut to a fixed length during processing.

[0003] Existing fixed-length cutting devices for heavy-duty tube bundle production have some shortcomings. Firstly, some devices simply use roller conveyors or rely on friction to propel the tube bundle forward. This makes the tube bundle prone to swaying and positional shifts during transport due to uneven power transmission or poor roller synchronization, thus affecting cutting quality and accuracy. Furthermore, this simple transport method is difficult to adapt to heavy-duty tube bundles of different diameters. For smaller diameters, the tube bundle may not be effectively clamped, leading to slippage during transport; for larger diameters, it may not fit tightly, causing swaying and shifting, affecting cutting accuracy. Secondly, some devices may use saw blades that only rotate in one direction or move simply up and down. This cutting method is less flexible when dealing with the complex materials and hardness of heavy-duty tube bundles, easily causing cutting jams and significant vibrations, resulting in uneven cut surfaces and reduced cutting quality. Utility Model Content

[0004] The purpose of this invention is to provide a fixed-length cutting device for heavy-duty tube bundle production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixed-length cutting device for heavy-duty tube bundle production, including a workbench, a cutting table on the right side of the workbench, a material collection box at the material outlet of the cutting table, a cutting frame slidably connected inside the cutting table, a feeding mechanism inside the workbench, and a cutting mechanism inside the cutting table.

[0006] The feeding mechanism includes an adjustment component and a transmission component, both of which are located inside the worktable.

[0007] Preferably, the adjusting component includes an adjusting threaded rod, which is rotatably connected between the top inner wall and the bottom inner wall of the front of the worktable. An adjusting wheel is fixedly connected to the top of the adjusting threaded rod, and a connecting rod is slidably connected inside the front of the worktable. Upper rollers are rotatably connected to both sides of the connecting rod.

[0008] Preferably, the connecting rod is threaded onto the surface of the adjustable pitch threaded rod.

[0009] Preferably, the transmission component includes a transmission motor, which is disposed on the front of the worktable. Two lower rollers are rotatably connected to the inner side of the worktable. A transmission belt is drivenly connected between the output end surface of the transmission motor and the surface of the lower roller on the right side. A gear set is fixedly connected to one end of the back of both the upper roller and the lower roller. A connecting rod set is rotatably connected to the surface of the gear set.

[0010] Preferably, the gear sets mesh with each other, and the lower roller on the left side is fixedly connected to the output end of the transmission motor.

[0011] Preferably, the cutting mechanism includes a cutting motor, which is mounted on the top of the cutting frame. A rotating disk is fixedly connected to the output end of the cutting motor. A saw blade is slidably connected to the bottom of the cutting frame. A cutting connecting rod is rotatably connected between the saw blade and the rotating disk. A pressing motor is mounted on the top of the cutting table. A pressing threaded rod is fixedly connected to the output end of the pressing motor. A fixed-length threaded rod is rotatably connected inside the cutting table. A fixed-length plate is threaded onto the surface of the fixed-length threaded rod.

[0012] Preferably, the cutting frame is threaded to the surface of the pressing threaded rod, and the material outlet of the cutting table adopts a ramp design.

[0013] Compared with the prior art, this utility model provides a fixed-length cutting device for heavy-duty tube bundle production, which has the following advantages:

[0014] 1. This fixed-length cutting device for heavy-duty tube bundle production allows for convenient adjustment of the distance between the upper and lower rollers via an adjustable distance assembly. This enables the device to adapt to heavy-duty tube bundles of different diameters, ensuring stable clamping and transmission of the tube bundles during transport. This avoids instability caused by differences in tube diameter. The transmission assembly utilizes a gear and linkage design, ensuring that the gears remain engaged even when the distance between the upper and lower rollers changes. This guarantees that the upper and lower rollers rotate synchronously and stably, ensuring subsequent cutting tasks. Furthermore, since the heavy-duty tube bundles are transported under compression, it also provides a certain straightening effect.

[0015] 2. This fixed-length cutting device for heavy-duty tube bundle production utilizes a cutting motor in the cutting mechanism to drive the saw blade in reciprocating motion via a rotating disk and cutting linkage. This design makes the saw blade's cutting action more flexible and efficient. The reciprocating motion of the saw blade is likely more advantageous when cutting heavy-duty tube bundles with different materials and hardness, reducing jamming and vibration during the cutting process, thereby improving cutting quality. The cutting frame is connected to the downward-pressing motor via a downward-pressing threaded rod, allowing for vertical movement. This enables adjustment of the saw blade's cutting height according to different tube diameters, making the cutting operation more precise. Simultaneously, the design of the fixed-length threaded rod and fixed-length plate facilitates adjustment of the fixed-length dimension, promoting accurate fixed-length cutting and effectively reducing cutting length errors.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] Example 1:

[0027] Please see Figure 1-5 This utility model provides a technical solution: a fixed-length cutting device for heavy tube bundle production, including a workbench 1, a cutting table 2 is provided on the right side of the workbench 1, a material collection box 3 is provided at the material outlet of the cutting table 2, a cutting frame 4 is slidably connected inside the cutting table 2, a feeding mechanism 5 is provided inside the workbench 1, and a cutting mechanism 6 is provided inside the cutting table 2.

[0028] The feeding mechanism 5 includes a distance adjustment component 51 and a transmission component 52, both of which are located inside the worktable 1.

[0029] Furthermore, the pitch adjustment assembly 51 includes a pitch adjustment threaded rod 511, which is rotatably connected between the top inner wall and the bottom inner wall of the front of the worktable 1. A pitch adjustment wheel 512 is fixedly connected to the top of the pitch adjustment threaded rod 511. A connecting rod 514 is slidably connected inside the front of the worktable 1. Upper rollers 513 are rotatably connected to both sides of the connecting rod 514. By sliding the connecting rod 514, the two upper rollers 513 can be driven to move up and down synchronously.

[0030] Furthermore, the connecting rod 514 is threaded onto the surface of the adjusting threaded rod 511. Rotating the adjusting wheel 512 can drive the adjusting threaded rod 511 to rotate, thereby causing the connecting rod 514 to move up and down.

[0031] Furthermore, the transmission component 52 includes a transmission motor 521, which is located on the front of the worktable 1. Two lower rollers 522 are rotatably connected to the inner side of the worktable 1. A transmission belt 523 is connected to the output end surface of the transmission motor 521 and the surface of the right lower roller 522. A gear set 524 is fixedly connected to one end of the back of both the upper roller 513 and the lower roller 522. A connecting rod set 525 is rotatably connected to the surface of the gear set 524. When the transmission motor 521 is started, it can drive the two lower rollers 522 to rotate together.

[0032] Furthermore, the gear sets 524 mesh with each other, and the lower roller 522 on the left is fixedly connected to the output end of the transmission motor 521. Since the length of the connecting rod assembly 525 is fixed, even if the distance between the upper roller 513 and the lower roller 522 changes, the gear sets 524 are still meshed. When the transmission motor 521 rotates, it can drive the gear sets 524 to rotate, thereby driving the upper roller 513 and the lower roller 522 to rotate together.

[0033] Example 2:

[0034] Please see Figure 6 In conjunction with Embodiment 1, the cutting mechanism 6 includes a cutting motor 61, which is mounted on the top of the cutting frame 4. A rotating disk 62 is fixedly connected to the output end of the cutting motor 61. A saw blade 63 is slidably connected to the bottom of the cutting frame 4. A cutting connecting rod 64 is rotatably connected between the saw blade 63 and the rotating disk 62. A pressing motor 65 is mounted on the top of the cutting table 2. A pressing threaded rod 66 is fixedly connected to the output end of the pressing motor 65. A fixed-length threaded rod 67 is rotatably connected inside the cutting table 2. A fixed-length plate 68 is threadedly connected to the surface of the fixed-length threaded rod 67. Starting the cutting motor 61 will drive the rotating disk 62 to rotate. Due to the cutting connecting rod 64, the saw blade 63 can be driven to reciprocate. When the fixed-length threaded rod 67 is rotated, the position of the fixed-length plate 68 can be changed.

[0035] Furthermore, the cutting frame 4 is threaded onto the surface of the pressing threaded rod 66. The discharge point of the cutting table 2 adopts a ramp design. Starting the pressing motor 65 can drive the pressing threaded rod 66 to rotate, thereby driving the cutting frame 4 to move up and down. When the cutting is completed, the cut heavy tube bundle will enter the discharge and storage box 3 from the ramp.

[0036] In actual operation, when this device is used, the heavy tube bundle needs to be inserted between the upper roller 513 and the lower roller 522. Rotate the adjusting wheel 512 to move the upper roller 513 down and press the heavy tube bundle. Rotate the fixed-length threaded rod 67 according to the desired cutting length to adjust the distance between the fixed-length plate 68 and the worktable 1. Start the transmission motor 521 to drive the upper roller 513 and the lower roller 522 to rotate together. Since the heavy tube bundle is in a pressed state, it will move forward. During the movement, the heavy tube bundle can be straightened to a certain extent. When the heavy tube bundle moves to the fixed-length plate 68, start the pressing motor 65 and the cutting motor 61. The pressing motor 65 will drive the cutting frame 4 down, and the cutting motor 61 will drive the saw blade 63 to reciprocate, thereby cutting the heavy tube bundle. When the cutting is completed, the heavy tube bundle will enter the discharge and storage box 3 from the ramp.
