Description

Technical Field

[0001] The present invention relates to the technical field of cable cutting, and in particular to an automatic cable cutting device and its working method. Background Art

[0002] In the production process of wire and cable, the traditional manual operation in the wire cutting process has significant limitations. The specific operation process requires two operators to cooperate: one is responsible for pulling the wire head to the cutting starting point for positioning, and the other needs to stretch the wire to the predetermined length end point for manual cutting. This operation mode exposes two prominent problems in practical applications: firstly, manual positioning is prone to deviation, resulting in difficulty in ensuring the length accuracy of the cut wire, directly affecting the consistency of product specifications; secondly, the double-operator cooperative operation process has time-consuming action connection, resulting in low output efficiency per unit time, and at the same time, the superposition effect of labor costs significantly increases the comprehensive production cost. Especially in the batch production scenario, the disadvantages of such traditional processes become more prominent, and it has become a bottleneck restricting the automation upgrade of cable manufacturing.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings.

[0022] Such as Figure 1As shown in the figure, the specific structure of the automated cable cutting device includes: a straightening component 1 for straightening and cutting cables, a loading component 2 for collecting the cut cables, and a traction component 3 for pulling the cables from the straightening component 1 to the loading component 2. First, the cable is straightened and cut by the straightening component 1, and then the straightened and cut cable is moved to the loading component 2 for collection by the traction component 3.

[0023] This device can achieve automated cable cutting, and the cutting length can be flexibly adjusted according to requirements. At the same time, the device has a built-in cable straightening function to ensure the accuracy of the cutting length and meet the requirements of high-precision processing. This device integrates the entire process of straightening, cutting, traction, and collection automation operations, realizing the full-chain automation of cable processing. It significantly improves production efficiency, optimizes the overall process flow, reduces manual intervention, and lowers production costs.

[0024] As Figure 2 、 3 As shown in the figure, the specific structure of the straightening component 1 includes a frame 101. A rotating mechanism 102 is arranged on the frame 101 for rotating and straightening the cable. A cutting mechanism 103 is arranged on the frame 101 for cutting the cable. In a specific implementation, a cable straightening pulley assembly is also arranged between the rotating mechanism 102 and the cutting mechanism 103, and the cable straightening pulley assembly can further straighten the cable. The cable straightening pulley assembly is a prior art. The cable passes through the rotating mechanism 102, the cable straightening pulley assembly, and the cutting mechanism 103 in sequence.

[0025] The specific structure of the rotating mechanism 102 includes a rotating seat 1021, and the rotating seat 1021 is fixedly connected to the frame 101. A rotating frame 1022 is rotatably arranged on the rotating seat 1021, and the rotating seat 1021 is located at both ends of the rotating frame 1022. Cross plates 1023 are arranged on opposite sides of the rotating frame 1022, and the opposite cross plates 1023 are arranged at intervals and offset. Inclined frames 1024 are arranged on the cross plates 1023. Rollers 1025 are rotatably arranged on the inclined frames 1024, and the rotation direction of the rollers 1025 is inclined to the rotation direction of the rotating frame 1022. The rotation of the rotating frame 1022 can drive the rollers 1025 to roll on the outer circumference of the cable, thereby straightening the cable.

[0026] Through the three-dimensional space straightening system composed of the rotating frame 1022 and the inclined rollers 1025, the device realizes the combined correction of axial torsion and radial bending of the cable. It effectively eliminates the influence of material springback on the cutting accuracy and ensures the stable and reliable processing quality.

[0027] The inclined frame 1024 is provided with a stud 1026 and a limiting shaft 1027. The stud 1026 is connected to the cross plate 1023 through a nut, and the limiting shaft 1027 is slidably inserted into the cross plate 1023.

[0028] The distance between the inclined frame 1024 and the cross plate 1023 can be adjusted by the stud 1026, so as to adjust the straightening force of the roller 1025 on the cable. The inclination angle of the inclined frame 1024 can be limited by the limit shaft 1027. In a specific implementation, the inclination angle of the inclined frame 1024 relative to the cross plate 1023 is 45°.

[0029] As Figure 4 、 5 As shown, the specific structure of the cutting mechanism 103 includes a moving frame 1031, and the moving frame 1031 is connected to the frame 101. In a specific implementation, two parallel guide columns 1035 are provided on the frame 101. A guide sleeve is provided at the lower end of the moving frame 1031, and the guide sleeve is slidably sleeved on the guide column 1035. A first spring 1036 is provided between the moving frame 1031 and the frame 101. The first spring 1036 is sleeved on the outer periphery of the guide column 1035, and both ends of the first spring 1036 are in contact with the frame 101 and the moving frame 1031 respectively. The wire threading block 1032 is provided on the moving frame 1031, and the wire threading block 1032 is provided with a through wire threading hole 1037, and the cable can slidably pass through the wire threading hole 1037 on the wire threading block 1032. The cutting knife 1033 is slidably connected to the wire threading block 1032, and the cutting knife 1033 is driven by a cutting cylinder 1034. The cutting knife 1033 can cut the cable in the wire threading block 1032.

[0030] The cable is located in the wire threading hole 1037, and the diameter of the wire threading hole 1037 is only slightly larger than the diameter of the cable, and the movement margin of the cable in the wire threading hole 1037 is very small. In addition, the cutting edge of the cutting knife 1033 is close to one end of the wire threading hole 1037. This layout and structure can ensure that the cable will not produce offset or deformation that affects the cutting accuracy during the cutting process of the cutting knife 1033.

[0031] As Figure 6 As shown, the specific structure of the traction assembly 3 includes a guide rail 304, and a chain 301 is rotatably provided on one side of the guide rail 304. The chain 301 is driven by a motor. A slider 302 is slidably provided in the guide rail 304, and the lower end surface of the slider 302 is connected to the chain 301, and the chain 301 drives the slider 302 to move along the guide rail 304. A clamping mechanism 303 is provided on the slider 302 for clamping the cable.

[0032] As Figure 7As shown in the figure, the specific structure of the clamping mechanism 303 includes a moving bracket 3031. The moving bracket 3031 is arranged on the slider 302, and the slider 302 can drive the moving bracket 3031 to move. The inner cylinder 3033 is fixedly connected to the moving bracket 3031. The clamping flap 3035 is hinged to the inner cylinder 3033. The torsion spring 3034 is arranged between the clamping flap 3035 and the inner cylinder 3033. The conical groove 3036 is arranged at the outer end of the clamping flap 3035. The clamping part 3037 is arranged at the inner end of the clamping flap 3035.

[0033] The torsion spring 3034 can drive the clamping flap 3035 to form a closed clamping cavity. At this time, the clamping flap 3035 reaches the critical state of geometric self-locking. The clamping flap 3035 generates a self-locking effect. The dual constraint mechanism formed by the elastic energy storage of the torsion spring 3034 and the dead point of the mechanism of the clamping flap 3035 can ensure that the clamping flap 3035 maintains a stable clamping state on the cable without external force intervention. The clamping mechanism 303 adopts a self-locking clamping design, and the clamping flap 3035 can firmly clamp the cable to ensure stability during the processing.

[0034] In specific implementation, the moving bracket 3031 is provided with a fixed sleeve 3032. The inner cylinder 3033 is inserted into the fixed sleeve 3032, and the inner cylinder 3033 and the fixed sleeve 3032 are fixed by bolts 3038.

[0035] With the above structure, it is possible to conveniently replace the inner cylinder 3033 of different specifications and the matching clamping flap 3035. By combining and matching the inner cylinder 3033 and the clamping flap 3035 of corresponding sizes, a clamping system suitable for cables of different diameters can be formed, realizing compatible operation of various specifications of cables.

[0036] As Figure 8 shown in the figure, the specific structure of the loading assembly 2 includes a fixed frame 201. An L-shaped frame for receiving the cable is arranged on one side of the fixed frame 201. The unloading chute 202 is rotatably arranged at the upper end of the fixed frame 201, and the unloading chute 202 is driven by an unloading cylinder 203. The unloading cylinder 203 can drive the unloading chute 202 to flip, so that the cable on the unloading chute 202 falls into the L-shaped frame on one side of the fixed frame 201.

[0037] The clamping mechanism 303 is located directly above the unloading chute 202, and the height of the clamping mechanism 303 is slightly higher than the height of the unloading chute 202. The drop of the cable is small, ensuring that the cable can stably fall into the unloading chute 202 after leaving the clamping mechanism 303.

[0038] The height of the wire threading hole 1037 is slightly higher than the height of the unloading chute 202. The cable spanning the wire threading hole 1037 and the unloading chute 202 in the natural state will not have a large inclination deformation due to the height difference between the wire threading hole 1037 and the unloading chute 202, thus ensuring the cutting accuracy of the cable.

[0039] AsFigure 9 As shown, a limiting mechanism 204 is provided at the upper end of the fixed frame 201. The specific structure of the limiting mechanism 204 includes an adjusting bracket 2041, and the adjusting bracket 2041 is provided on the fixed frame 201. The adjusting bracket 2041 has multiple installation positions on the fixed frame 201, and can be multi-stage positionally adjusted on the fixed frame 201, and can be linked to control the stroke parameters of the clamping mechanism 303, so as to accurately adapt to the fixed-length cutting requirements of cables of different specifications. The sliding shaft 2042 is slidably provided on the adjusting bracket 2041. The second spring 2043 is provided between the sliding shaft 2042 and the adjusting bracket 2041. The second spring 2043 is sleeved on the outer periphery of the sliding shaft 2042. The limiting platform 2044 is provided at the front end of the sliding shaft 2042. The two ends of the second spring 2043 are respectively in contact with the adjusting bracket 2041 and the limiting platform 2044. The frustum 2045 is arranged at the front end of the limiting platform 2044, and the frustum 2045 cooperates with the conical groove 3036. The through groove 2046 runs through the frustum 2045, the limiting platform 2044 and the sliding shaft 2042. The through groove 2046 is used to accommodate the cable.

[0040] The cone 2045 forms a kinematic pair with the cone groove 3036 of the clamping flap 3035 through its cone surface. When the clamping mechanism 303 moves toward the cone 2045, the radial component force generated by the cone surface of the cone 2045 drives the clamping flap 3035 to achieve synchronous radial expansion, thereby quickly releasing the clamping constraint on the cable. The mechanical decoupling device can accurately control the opening and closing state of the clamping mechanism 303. The structural design of the cone 2045 of the limiting mechanism 204 enables the clamping flap 3035 to quickly release the clamping of the cable, greatly improving the transfer efficiency of the cable. Not only is the structure simple, but it also facilitates the transfer of the cable and improves the convenience of operation.

[0041] The working process of the clamping mechanism 303 and the cable is further supplemented. Figure 10 , 11 As shown, in the L1 stroke, that is, when the clamping mechanism 303 moves in the direction away from the cutting mechanism 103, the cone 2045 continuously acts on the cone groove 3036, and through the mechanical transmission of the cone surface matching, the clamping petal 3035 is always in a radial expansion state. This linkage mechanism effectively reduces the resistance between the clamping mechanism 303 and the cable, ensuring that the cable can be separated from the clamping mechanism 303 within the predetermined stroke.

[0042] During the L2 stroke, the second spring 2043 keeps the clamping flap 3035 in a radially expanded state, and the cable is separated from the clamping mechanism 303. As the clamping mechanism 303 moves further, the second spring 2043 is further shortened, and the through slot 2046 also moves further, and the cable will be separated from the clamping mechanism 303 and the through slot 2046 and fall onto the discharge chute 202.

[0043] During the L3 stroke, after the cable detaches from the clamping mechanism 303, the clamping mechanism 303 returns to its initial position.

[0044] The working method of the automatic cable cutting device includes the following steps: a. The cable is straightened by the rotation of the rotating mechanism 102 and then passes through the threading block 1032.

[0045] b. The cutter 1033 cuts the cable in the threading block 1032, and after cutting, the cutter 1033 resets.

[0046] c. The traction assembly 3 drives the clamping mechanism 303 to move towards the cutting mechanism 103. The moving bracket 3031 pushes the threading block 1032 to move. The cable in the threading block 1032 extends out of the threading block 1032 and is inserted into the clamping part 3037, and the clamping part 3037 clamps and fixes the cable.

[0047] As Figure 12 shown, when the clamping mechanism 303 moves towards the cutting mechanism 103, the cable is inserted into the inner cylinder 3033. The outer end of the cable can abut against the end face of the clamping flap 3035 facing the inner cylinder 3033, which causes the clamping flap 3035 to expand outward along the radial direction of the inner cylinder 3033 with the hinge point as the fulcrum.

[0048] Until the outer end of the cable moves to the clamping part 3037. Under the action of the torsion spring 3034, the clamping part 3037 clamps on the outer circumference of the cable.

[0049] It should be noted that due to the large resistance between the cable and the rotating mechanism 102, when the threading block 1032 moves, the position of the cable in the threading block 1032 remains fixed, so that the cable in the threading block 1032 extends out of the threading block 1032 and is inserted into the clamping part 3037.

[0050] d. The traction assembly 3 drives the clamping mechanism 303 to move away from the cutting mechanism 103, and the clamping mechanism 303 pulls the cable to the discharge chute 202.

[0051] As Figure 12 shown, when the clamping mechanism 303 moves away from the cutting mechanism 103, the frictional force between the cable and the clamping part 3037 drives the clamping flap 3035 to retract inward along the radial direction of the inner cylinder 3033 with the hinge point as the fulcrum. Until several clamping flaps 3035 form a closed cylindrical cavity. At this time, the cable is firmly clamped between the clamping parts 3037 of several clamping flaps 3035, and several clamping flaps 3035 achieve self-locking clamping on the cable. The clamping mechanism 303 can pull the cable to move.

[0052] e. When the clamping mechanism 303 cooperates with the limiting mechanism 204, the frustum 2045 expands the clamping flaps 3035 through the conical groove 3036, and the cable is separated from the clamping portion 3037.

[0053] f. The clamping mechanism 303 continues to move until the cable is separated from the clamping mechanism 303 and falls onto the discharge chute 202.

[0054] It should be noted that during the continuous movement of the clamping mechanism 303, the second spring 2043 is forced to produce a progressive compression deformation. This elastic deformation drives the frustum 2045 to continuously act on the conical groove 3036. Through the mechanical transmission of the conical surface fit, the clamping flaps 3035 are always in a radially expanded state. This linkage mechanism effectively reduces the resistance between the clamping mechanism 303 and the cable, ensuring that the cable can be separated from the clamping mechanism 303 within a predetermined stroke.

[0055] g. The cutting mechanism 103 cuts the other end of the cable, and the entire cable falls onto the discharge chute 202.

[0056] h. The discharge chute 202 flips, and the cable falls onto the fixing frame 201.
