Description

Technical Field

[0001] This utility model belongs to the field of cable processing technology, and specifically relates to a cutting device for cable processing production. Background Technology

[0002] Cables are a general term for items such as optical cables and electrical cables. During their processing and production, the processed cables need to be wound onto cable reels for placement, transportation, or storage. When the cable is wound to a certain length, it needs to be cut, replaced with a new cable reel, and then wound up again.

[0003] Existing technologies disclose cutting devices related to cable processing and production. For example, patent CN221133875U discloses a cutting device for wire and cable production, including a processing table and a cutting frame. One end of the processing table is equipped with an active roller and a driven frame. A moving block is sleeved in the moving groove inside the driven frame. A first telescopic rod is provided at the top of the moving block. A driven roller connected to the bearing of the moving block is provided on the outside of the moving groove. A cutting knife is provided at the bottom of the cutting frame. The height of the driven roller is adjusted by the first telescopic rod. The active roller and the driven roller automatically feed the cable. The cutting knife of the cutting frame automatically cuts the fed cable, which is convenient for automatic feeding and cutting of cables of different specifications.

[0004] Undeniably, the cutting device for wire and cable production disclosed in this patent can indeed achieve the above-mentioned effects, but it still has some shortcomings: it mainly relies on the second telescopic rod and the cutting tool to cut the cable, without limiting and fixing the cable. This situation can easily cause the cutting point to shift, resulting in a skewed cut, affecting the quality of the cable end face, and increasing the workload of subsequent processing (such as crimping terminals).

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this utility model is to provide a cutting device for cable processing and production, so as to solve the problems existing in the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A cutting device for cable processing and production, comprising:

[0009] Workbench;

[0010] The cutting assembly includes a cutting frame fixed to the top of the workbench, a cutting cylinder fixed to the top of the cutting frame with its telescopic end extending vertically downward through the cutting frame, a lifting plate fixed to the telescopic end of the cutting cylinder, a movable blade fixed to one side of the bottom of the lifting plate, and a fixed blade fixed to the bottom of the cutting frame; wherein the blade of the movable blade is vertically downward, the blade of the fixed blade is vertically upward, and when the movable blade moves downward to the bottom of the cutting frame, the sides of the movable blade and the fixed blade that are close to each other are in contact;

[0011] The limiting assembly includes a fixed frame fixed to the bottom of the cutting frame and located in front of the fixed blade, a movable frame fixed to the bottom of the lifting plate and located in front of the movable blade, and two limiting rods fixed at intervals along the length of the movable frame and vertically extending through the lifting plate; wherein, a limiting cap is fixed to the top of the limiting rod;

[0012] Guide components are spaced apart on the front and rear sides of the cutting component.

[0013] Furthermore, the moving blade has an upwardly recessed center; the fixed blade has a downwardly recessed center.

[0014] Furthermore, the cutting assembly also includes two guide rods that are fixed at intervals along the length of the lifting plate to the top of the lifting plate and extend vertically upward through the top of the cutting frame.

[0015] Furthermore, the limiting component also includes a return spring sleeved on the limiting rod, with the bottom of the return spring abutting against the movable frame and the top abutting against the lifting plate.

[0016] Furthermore, the movable frame and the fixed frame are vertically aligned; the bottom center of the movable frame is recessed upward to form an upper limit groove, and the top center of the fixed frame is recessed downward to form a lower limit groove, with the upper limit groove and the lower limit groove being vertically aligned.

[0017] Furthermore, the guide assembly includes two fixed plates fixed at intervals along the width direction of the workbench, two rotating shafts arranged vertically at intervals, and guide wheels fixed on the rotating shafts; wherein, both ends of the rotating shafts pass through the fixed plates and are rotatably connected to the fixed plates; and the guide wheels have an arc-shaped guide groove in the middle.

[0018] Furthermore, a drive motor is fixed to the outer side of one of the guide component fixing plates on the front side of the cutting assembly, and the output shaft of the drive motor is connected to the outer end of the upper rotating shaft through a coupling.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) The upper moving frame upper limit groove and the lower moving lower limit groove of the limit component of this utility model can firmly limit and fix the cable before the cable cutting action occurs, so that the cable cutting end face is neat and vertical, ensuring the quality of the cable cutting end face and helping to improve the efficiency of subsequent processing.

[0021] (2) In the cutting assembly of this utility model, the guide rod ensures that the lifting plate can only drive the moving blade to move in the vertical direction, avoiding offset and shaking caused by cylinder or structural gaps; similarly, the limit rod ensures the vertical movement trajectory of the moving frame. By setting the guide rod and the limit rod, the stability of the entire device is enhanced, making the cable cutting process smoother and more precise.

[0022] (3) The guide groove of the guide wheel of this utility model guides the path of the cable, ensuring that the cable can accurately fall into the lower limit groove of the fixed frame when it enters the cutting area, and then be pressed by the upper limit groove, which helps to improve the efficiency of cable cutting operation.

[0023] (4) This utility model utilizes the descent action of the same cylinder to first drive the moving frame to complete the cable limit and fixation, then compress the return spring and drive the moving knife to complete the cutting action, and finally reset the moving frame by the return spring when the cylinder returns, thus realizing the linkage between the moving frame limit and the cutting action. The structure is compact and the action sequence is reasonable.

[0024] In summary, this invention, by incorporating a cutting component, a limiting component, and a guiding component, ensures that the cable is firmly fixed and limited during the cutting action, effectively solving the problem of skewed cuts and improving the quality of the cut surface. Furthermore, the guide rod and limiting rod ensure motion accuracy, while the return spring provides cushioning and automatic reset. These features enable fast and high-quality cable cutting.

[0037] Example

[0038] See Figure 1-6 A cutting device for cable processing and production, comprising:

[0039] Workbench 1;

[0040] The cutting assembly 2 includes a cutting frame 21 fixed to the top of the workbench 1, a cutting cylinder 22 fixed to the top of the cutting frame 21 with its telescopic end extending vertically downward through the cutting frame 21, a lifting plate 23 fixed to the telescopic end of the cutting cylinder 22, a moving blade 24 fixed to one side of the bottom of the lifting plate 23, a fixed blade 25 fixed to the bottom of the cutting frame 21, and two guide rods 26 fixed at intervals along the length of the lifting plate 23 to the top of the lifting plate 23 with their tops extending vertically upward through the top of the cutting frame 21; wherein, the blade of the moving blade 24 is vertically downward, the blade of the fixed blade 25 is vertically upward, and the middle of the blade of the moving blade 24 is concave upward, while the middle of the blade of the fixed blade 25 is concave downward; when the moving blade 24 moves downward to the bottom of the cutting frame 21, the sides of the moving blade 24 and the fixed blade 25 approach each other and fit together, so that the fixed blade 25 does not interfere with the movement of the moving blade 24;

[0041] The limiting assembly 3 includes a fixed frame 31 fixed to the bottom of the cutting frame 21 and located in front of the fixed blade 25, a movable frame 32 fixed to the bottom of the lifting plate 23 and located in front of the movable blade 24, two limiting rods 33 fixed at intervals along the length of the movable frame 32 and vertically extending through the lifting plate 23, and a return spring 34 sleeved on the limiting rods 33; wherein, a limiting cap 35 is fixed to the top of the limiting rod 33; the bottom of the return spring 34 abuts against the movable frame 32, and the top of the return spring 34 abuts against the lifting plate 23;

[0042] Guide components 4 are spaced apart on the front and rear sides of the cutting component 2. Guide components 4 include two fixed plates 41 fixed at intervals along the width direction of the workbench 1, two rotating shafts 42 spaced apart vertically, and guide wheels 43 fixed on the rotating shafts 42. The two ends of the rotating shafts 42 pass through the fixed plates 41 and are rotatably connected to the fixed plates 41. The guide wheels 43 have an arc-shaped guide groove 431 in the middle. In this embodiment, a drive motor 44 is fixed on the outer side of one of the guide components 4 fixed plates 41 on the front side of the cutting component 2. The output shaft of the drive motor 44 is connected to the outer end of the upper rotating shaft 42 through a coupling.

[0043] In this embodiment, the movable frame 32 and the fixed frame 31 are vertically aligned; the upper limit groove 321 is formed by an upward recess at the middle of the bottom of the movable frame 32, and the lower limit groove 311 is formed by a downward recess at the middle of the top of the fixed frame 31. The upper limit groove 321 and the lower limit groove 311 are vertically aligned.

[0044] It should be noted that in this embodiment, the drive motor 44 is connected to an external power source to cut off the air supply to the cylinder 22 connection; the position of the guide groove 431 of the lower guide wheel 43 corresponds to the position of the lower limit groove 311 of the fixed frame 31; the bottom of the moving frame 32 is lower than the bottom of the moving blade 24 to ensure that the upper limit groove 321 of the moving frame 32 contacts the cut cable first, thereby limiting and fixing the cable; the lowest point of the lower limit groove 311 is not lower than the lowest point of the middle of the blade of the fixed blade 25 to avoid the blade of the fixed blade 25 interfering with the movement of the cable;

[0045] In use, the cable to be wound passes sequentially through the guide assembly 4 on the front side of the cutting assembly 2. The cable is located between the guide grooves 431 of the upper and lower guide wheels 43, and the cable makes frictional contact with the guide grooves 431 that it contacts. It should be noted that the diameter of the cable is larger than the distance between the upper and lower guide grooves 431. Since the cable sheath is elastic, when the cable enters between the upper and lower limiting grooves 311, the cable sheath is squeezed and contracted by the guide grooves 431, which can ensure sufficient friction between the cable and the limiting grooves so that the subsequent drive motor 44 can drive the cable to move. When the drive motor 44 starts, the drive motor 44 drives the rotating shaft 42 connected to it to rotate, and the rotating shaft 42 drives the corresponding guide wheel 43 to rotate. When the guide wheel 43 rotates, it relies on the friction between the guide groove 431 and the outer surface of the cable to drive the cable to move in the direction of the cutting assembly 2.

[0046] When the cable to be wound passes through all the guide components 4 and is wound onto the external cable reel, and is wound to a suitable length to be cut, the drive motor 44 is turned off and the rotation of the external cable reel stops. The extension end of the control cutting cylinder 22 extends, driving the lifting plate 23 to move downward. After the lifting plate 23 moves downward a certain distance, the upper limit groove 321 of the moving frame 32 presses against the top of the cable, and the bottom of the cable is located in the lower limit groove 311. In this way, the upper limit groove 321 and the lower limit groove 311 can limit and fix the cable. When the lifting plate 23 continues to move downward, the moving frame 32 stops moving downward, the return spring 34 is compressed, the moving blade 24 continues to move downward, and the moving blade 24 and the fixed blade 25 cut the cable. Then, control the retraction end of the cutting cylinder 22 to retract, the lifting plate 23 and the moving knife 24 to move upward, the upper limit groove 321 of the moving frame 32 to separate from the cable, the reset spring 34 to reset, and control the cutting cylinder 22 to stop when the retraction end of the cutting cylinder 22 returns to the initial position.

[0047] When the lifting plate 23 moves up and down, the two guide rods 26 slide and guide with the cutting frame 21, limiting the movement trajectory of the lifting plate 23 and preventing it from deviating during its movement. Similarly, during the movement of the moving frame 32, the two limiting rods 33 slide and guide with the lifting plate 23, limiting the movement trajectory of the moving frame 32 and preventing it from deviating during its movement. The guide rods 26 and the limiting rods 33 improve the reliability and stability of the device in this application.

[0048] Finally, it should be noted that when cutting cables of different diameters, it is necessary to select and replace the appropriate guide assembly 4.

[0049] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings. The exemplary embodiments were chosen and described in order to explain the specific principles of the present invention and its practical application, thereby enabling those skilled in the art to implement and utilize various different exemplary embodiments of the present invention, as well as various different choices and variations.
