Description

Technical Field

[0001] This invention relates to the technical field of cutting devices, and in particular to a cutting device for cable production. Background Technology

[0002] A cable is a device for transmitting electrical energy or signals, typically composed of several or groups of conductors. With societal development and technological advancements, the cable manufacturing technology field has witnessed significant progress. Within this field, a crucial step in cable production is the use of cutting devices to cut cables during the manufacturing process.

[0003] Currently, cable cutting devices on the market require workers to first fix the cable on a workbench before using the device to cut it. This process is cumbersome, inconvenient, increases workload, and significantly impacts efficiency, resulting in poor practicality. Patent CN116140505A discloses a cable cutting device where, during use, the worker first starts a servo motor in the transmission assembly. The output shaft of the servo motor drives a first bevel gear to rotate, which in turn drives a second bevel gear, which in turn drives a reciprocating screw. This causes a moving block to move vertically downwards within a rotating groove. The moving block then moves a connecting block downwards, which in turn moves a lifting plate vertically downwards, thus raising and lowering the cable. The plate moves the cutter vertically downwards until it cuts the cable. Then, under the action of the reciprocating screw, the cutter moves vertically upwards. The reciprocating screw continuously drives the cutter to move up and down, thus continuously cutting the cable. The operation is simple and effectively improves work efficiency. However, in actual use, although the lifting plate, moving rod, slider, telescopic spring, connecting rod, reciprocating screw and transmission components can fix the cable while cutting it, eliminating the need for workers to fix the cable beforehand, the sliding range of the telescopic spring and moving rod cannot be adjusted. This results in the same clamping force being maintained when cutting different types and models of cables, leading to poor limiting effect and inconvenience in use. Summary of the Invention

[0004] The purpose of this invention is to provide a cutting device for cable production to solve the problems mentioned in the background art.

[0005] The technical solution adopted in this invention is: A cable cutting device for cable production includes: a processing table with a column fixedly connected to its top; an adjustment mechanism disposed on the column; a mounting block slidably connected to the side of the column, the adjustment mechanism being used to adjust the height of the mounting block; a mounting frame fixedly connected to the bottom of the mounting block; a knife holder fixedly connected to the bottom of the mounting frame; a cutting blade fixedly connected to the bottom of the knife holder; a first fixed seat fixedly connected to the processing table; a second fixed seat disposed on the first fixed seat; a limiting rod slidably connected to the second fixed seat; a pressure plate fixedly connected to the top of the limiting rod; a round-headed rod slidably connected to the knife holder; a spring sleeved on the outside of the first round-headed rod; a pad fixedly connected to the bottom end of the first spring; a clamping plate fixedly connected to the pressure plate and the second fixed seat facing each other; a groove formed on the side of the mounting frame; a slider slidably connected within the groove; and a set bolt threadedly connected to the slider, one end of the set bolt abutting against the mounting frame.

[0006] Optionally, the second fixed seat, the limiting rod, the pressure plate, the first round-headed rod, the first spring, and the pad are a group, and multiple groups are provided between the first fixed seat and the tool holder.

[0007] Optionally, the slider is in the shape of an I-beam.

[0008] Optionally, the bottom end of the pad is lower than the bottom end of the cutter.

[0009] Optionally, a slot is provided on the first fixing seat, the second fixing seat is inserted into the slot, a round-headed rod is slidably connected to the first fixing seat, a spring is sleeved on the outside of the round-headed rod, and one end of the round-headed rod is inserted into the second fixing seat.

[0010] Optionally, the round-headed rod 2 and the spring 2 are a set, and multiple sets are provided on the fixing seat 1.

[0011] Optionally, the fixed base two has a cavity, a push block is slidably connected in the cavity, a push rod is fixedly connected to one side of the push block, and one end of the push rod is pressed against the round-headed rod two.

[0012] Optionally, both the push block and the limiting rod are provided with inclined surfaces.

[0013] Compared with the prior art, the beneficial effects of the present invention are: In use, after the clamping plate contacts the cable, the adjustment mechanism is activated, allowing the clamping plate to limit the cable's movement. Then, the cutter contacts the cable and cuts it. The slider limits the sliding range of the round-headed rod, ensuring that when cutting the cable, the pad presses against the pressure plate, and the clamping plate on the pressure plate always clamps the cable, providing a good limiting effect and preventing cable displacement, thus improving stability. By manually pushing the slider, its height can be adjusted. Increasing the slider height increases the sliding range of the round-headed rod, and vice versa, changing the maximum height and sliding range of the pad, indirectly altering the pushing force of the pad on the pressure plate, and thus adjusting the clamping force on the cable. This expands the device's applicability and improves its practicality, solving the problem that existing cable cutting devices lack adequate limiting and adjustment functions.

[0017] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use, or the orientation or positional relationship commonly understood by those skilled in the art. They are only used to facilitate the description of this invention and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0018] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0019] In the current technology, the operator first starts the servo motor in the transmission assembly. The output shaft of the servo motor drives the first bevel gear to rotate, which in turn drives the second bevel gear to rotate. The second bevel gear then drives the reciprocating screw to rotate, causing the moving block to move vertically downward within the rotating groove. The moving block then drives the connecting block to move downward, which in turn drives the lifting plate to move vertically downward. The lifting plate then drives the cutter to move vertically downward until the cutter cuts the cable. Finally, under the action of the reciprocating screw, the cutter moves vertically upward. The reciprocating screw continuously drives the cutter to move up and down repeatedly. The device allows for continuous cable cutting through movement, simplifying operation and improving work efficiency. However, in actual use, although the lifting plate, moving rod, slider, telescopic spring, connecting rod, reciprocating screw, and transmission components work together to simultaneously fix the cable during cutting, eliminating the need for pre-fixation by personnel, the inability to adjust the sliding range of the telescopic spring and moving rod results in a situation where the same clamping force is maintained when cutting different types and models of cables, leading to poor limiting effect and inconvenience.

[0020] like Figure 1-3As shown, this embodiment of the invention provides a cable cutting device, comprising: a processing table 10 with a column 11 fixedly connected to its top; an adjustment mechanism 12 disposed on the column 11; a mounting block 13 slidably connected to the side of the column 11, the adjustment mechanism 12 being used to adjust the height of the mounting block 13; a mounting frame 14 fixedly connected to the bottom of the mounting block 13; a knife holder 15 fixedly connected to the bottom of the mounting frame 14; a cutting blade 16 fixedly connected to the bottom of the knife holder 15; a first fixing seat 20 fixedly connected to the processing table 10; and a second fixing seat 21 disposed on the first fixing seat 20. The limiting rod 22 is slidably connected to the fixed seat 21; the pressure plate 23 is fixedly connected to the top of the limiting rod 22; the round-headed rod 24 is slidably connected to the knife holder 15; the spring 25 is sleeved on the outside of the round-headed rod 24; the pad 26 is fixedly connected to the bottom end of the spring 25; the clamping plate 27 is fixedly connected to the opposing surfaces of the pressure plate 23 and the fixed seat 21; the slide groove 30 is opened on the side of the mounting frame 14; the slider 31 is slidably connected in the slide groove 30; the set bolt 32 is threadedly connected to the slider 31, and one end of the set bolt 32 abuts against the mounting frame 14.

[0021] After placing the processing table 10 in the designated position, pull the pressure plate 23 upwards, causing the pressure plate 23 to slide the limit rod 22 out of the fixed seat 21. Then, pass the cable to be processed between the upper and lower clamping plates 27, release the pressure plate 23, and ensure that both clamping plates 27 are in contact with the cable. Then, activate the adjustment mechanism 12 to adjust the height of the mounting block 13, causing the mounting block 13 to slide downwards along with the mounting frame 14, the tool holder 15, and the cutter 16. Simultaneously, the tool holder 15 causes the round-headed rod 24 to slide downwards. Subsequently, the pad 26 at the bottom of the round-headed rod 24 contacts the pressure plate 23 first, pushing the pressure plate 23 to generate a downward force. The clamping plate 27 acts on the cable to limit its movement. Then, as the cutter 16 continues to slide downwards, the round-headed rod 24 slides on the cutter 15 and pulls the spring 25. After the cutter 16 contacts the cable, it cuts the cable. While the round-headed rod 24 slides on the cutter 15, the sliding range of the round-headed rod 24 is limited by the slider 31. When the cable is cut, the pad 26 presses the pressure plate 23, and the clamping plate 27 on the pressure plate 23 always clamps the cable, which has a good limiting effect on the cable, thereby preventing the cable position from shifting and improving stability. After unlocking the slider 31 by rotating the set bolt 32, the slider 31 can be manually pushed to slide up and down in the groove 30. After adjusting the height of the slider 31, the set bolt 32 is rotated again to lock the position of the slider 31. When the subsequent knife holder 15 slides down, the sliding range of the round-head rod 24 is changed. When the height of the slider 31 increases, the sliding range of the round-head rod 24 increases, and vice versa. This changes the maximum height and sliding range of the pad 26, indirectly changing the pushing force of the pad 26 on the pressure plate 23, thereby adjusting the clamping force of the clamp 27 on the cable, increasing the applicability of the device and improving its practicality.

[0022] Furthermore, the fixed seat 21, the limiting rod 22, the pressure plate 23, the round-head rod 24, the spring 25, and the pad 26 are a group. Multiple groups are provided between the fixed seat 20 and the knife holder 15. When the knife holder 15 slides downward, it drives the two round-head rods 24 and the two pads 26 to slide downward at the same time. This causes the pads 26 to push the two pressure plates 23, so that the two clamping plates 27 on the pressure plates 23 can clamp and limit the two positions of the cable at the same time, which facilitates the subsequent cutting operation.

[0023] Furthermore, the slider 31 is generally H-shaped, which allows the slider 31 to slide only longitudinally, making its sliding more stable.

[0024] Furthermore, the bottom end of the pad 26 is lower than the bottom end of the cutter 16, so that the pad 26 contacts the pressure plate 23 first, thereby achieving a better limiting effect on the cable.

[0025] Furthermore, a slot 40 is provided on the first fixing seat 20, and the second fixing seat 21 is inserted into the slot 40. A round-headed rod 41 is slidably connected to the first fixing seat 20, and a spring 42 is sleeved on the outside of the round-headed rod 41. One end of the round-headed rod 41 is inserted into the second fixing seat 21.

[0026] When it is necessary to disassemble and maintain the second fixed base 21 and its structure, pull the second round-headed rod 41 outward so that it slides outward on the first fixed base 20. At the same time, pull the second spring 42 until one end of the second round-headed rod 41 slides out of the second fixed base 21. After that, release the limit on the second fixed base 21 and pull the second fixed base 21 directly upward so that the second fixed base 21 slides out of the slot 40. This allows for the disassembly of the second fixed base 21, which facilitates the disassembly, maintenance or replacement of the second fixed base 21 and its structure, thus improving its practicality.

[0027] Furthermore, the round-headed rod 41 and the spring 42 are a set, and multiple sets are provided on the fixed seat 20, so that multiple round-headed rods 41 can simultaneously limit the fixed seat 21, thereby improving stability.

[0028] Furthermore, a cavity 50 is provided inside the fixed base 21, and a push block 51 is slidably connected inside the cavity 50. A push rod 52 is fixedly connected to one side of the push block 51, and one end of the push rod 52 abuts against the round-headed rod 41.

[0029] When there is a cable between the two clamping plates 27, the bottom end of the limiting rod 22 will not contact the push block 51, so that the push block 51 will not work during normal cutting operations. When there is no cable between the two clamping plates 27, the bottom end of the limiting rod 22 will contact the push block 51. At this time, the pressure plate 23 is pushed down, so that the pressure plate 23 pushes the push block 51 through the limiting rod 22, so that the push block 51 pushes the round-headed rod 41 out of the fixed seat 21 through the push rod 52. Moreover, one hand can push the two pressure plates 23 at the same time, so that multiple round-headed rods 41 slide out at the same time. Then, it is convenient to directly pull the fixed seat 21 for disassembly operations, improving disassembly efficiency.

[0030] Furthermore, both the push block 51 and the limiting rod 22 are provided with inclined surfaces. When the limiting rod 22 slides downward, the inclined surface at the bottom of the limiting rod 22 contacts the inclined surface at the top of the push block 51, causing the inclined surface at the top of the push block 51 to be subjected to force and slide outward, thereby pushing the push rod 52, which facilitates the subsequent pushing of the round-headed rod 41 out of the fixed seat 21.

[0031] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
