Description

Technical Field

[0001] This utility model relates to the technical field of cable cutting equipment, specifically a cutting device for cable production. Background Technology

[0002] Currently, cable cutting is a common process in cable production and processing. Existing cable cutting devices mostly employ a single-sided blade or a top-and-bottom cutting blade structure, using external force to drive the blades to complete the cut. While these devices are relatively simple in structure and can meet the cutting requirements of some cables, they still have the following shortcomings in practical applications: Traditional unidirectional cutting methods can only cut cables from one direction, which can easily lead to slanted cuts or uneven cutting, especially when processing large-section cables, making it more likely to damage the core material and affect the cable's performance. Existing devices with an upper and lower cutting structure can improve the cutting effect to some extent, but due to the limited number of cutters and insufficient force points, uneven cutting surfaces and incomplete cuts still occur, leading to inconvenience in subsequent operations.

[0003] In addition, existing devices mostly rely on complex drive or multi-point clamping structures in their structural design, which not only has high processing costs, but also makes adjustment and maintenance cumbersome, making it difficult to meet the high-efficiency cutting requirements of cables of different specifications.

[0004] Therefore, existing cable cutting technologies generally suffer from problems such as insufficient cutting accuracy, poor protection of cable core materials, complex structure, and limited applicability. There is an urgent need to propose a cable cutting device that can achieve multi-directional synchronous cutting, has a simple structure, and is highly adaptable, so as to improve the efficiency and reliability of cutting. Utility Model Content

[0005] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the technical solution adopted by this utility model is as follows: a cutting device for cable production, including a fixed base, a fixed ring disk, a rotating ring disk, and a drive rod for driving the rotating ring disk to deflect. The surfaces of the fixed ring disk and the rotating ring disk are respectively provided with a radial groove and an arc groove. The Type I and Type II cutters in the cutting blade assembly are slidably sleeved on the inner sides of the radial groove and the arc groove via sliding pins. Through the deflection motion of the rotating ring disk, the arc groove drives the sliding pin to move relative to it, thereby driving the cutting blade assembly to achieve radial linear cutting along the radial groove.

[0007] Specifically, the design achieves synchronous radial convergence of the cutting blade assembly, enabling the cable to be cut evenly under multi-directional force, thus avoiding the problem of uneven cutting by a single blade.

[0008] In a preferred example, both the Type I cutter and the Type II cutter are slidably mounted on the inner side of the fixed ring disk, and the rotating ring disk is rotatably mounted on one side of the fixed ring disk.

[0009] Specifically, this structure ensures the stability and guidance of the cutting tool assembly during movement, improving the accuracy and smoothness of cutting.

[0010] In a preferred example, the fixed ring disk has an arc-shaped structure with slots on its surface for cable placement and radial grooves for limiting the radial guiding movement of the sliding pin.

[0011] Specifically, this structure facilitates quick cable positioning and centering, ensuring the accuracy of the cutting position.

[0012] In a preferred example, the rotating disc is an arc-shaped structure with a groove on its surface corresponding to the cable. In the initial state, it coincides with the groove of the fixed disc. The arc groove and the radial groove cooperate with each other to form the sliding channel of the sliding pin.

[0013] Specifically, the design allows the cable to be easily inserted and secured, and the cutter assembly operates stably and has a controllable trajectory during the cutting process.

[0014] In a preferred example, the Type I cutter has a fan-shaped structure with a right angle at the center, and there are two of them arranged opposite each other; the Type II cutter has a fan-shaped acute-angle structure, and there are at least three of them, which are arranged alternately with the Type I cutter along the circumference.

[0015] Specifically, this combined structure can cut the cable at different angles to achieve a complete and uniform cutting effect, avoiding residue or incomplete cutting.

[0016] In a preferred example, the sliding pin engages with both the radial and arc-shaped sliding grooves to achieve radial linear motion when the rotating disc deflects.

[0017] Specifically, this design effectively converts the deflection motion of the rotating disc into the radial linear motion of the cutting tool assembly, ensuring the stability and reliability of the cutting process.

[0018] In a preferred example, one end of the rotating disk is provided with an ear plate, which is connected to a drive rod, thereby achieving the deflection of the rotating disk through the operation of the drive rod.

[0019] Specifically, the design simplifies the drive structure, making it easier for operators to quickly control the movement of the cutter assembly and reducing the difficulty of using the device.

[0020] The beneficial effects achieved by this utility model are as follows: 1. In this invention, through the coordinated operation of the fixed ring disc, rotating ring disc, radial slide groove, arc slide groove, and cutting blade assembly, the radial linear cutting motion of the I-shaped cutter and the II-shaped cutter can be achieved under the drive of the drive rod, thereby ensuring uniform cutting of the cable. Compared with existing devices that rely on unidirectional cutting blades, this invention can simultaneously approach the cable from multiple directions, avoiding miscutting or damage to the core material, and significantly improving the stability and reliability of cutting.

[0021] 2. In this utility model, the I-shaped cutter and the II-shaped cutter are arranged alternately in a circumferential direction, and synchronously converge to cut under the cooperation of the sliding pin, thereby forming a ring-shaped cutting edge, which can achieve rapid and complete cutting of cables. This structure not only improves cutting efficiency, but also simplifies the driving method, and can achieve stable operation without complex control. It has the advantages of compact structure, high degree of automation, and wide applicability. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0025] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0026] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a cutting device for cable production.

[0027] Combination Figures 1-5 As shown, the present invention provides a cutting device for cable production, including a fixed base 100, a fixed ring plate 200, a rotating ring plate 300, a drive rod 110, a cutting blade assembly 400, and several mating parts.

[0028] The fixing base 100 is used to support and fix the overall structure. A fixed ring disk 200 is fixedly connected to its surface. The fixed ring disk 200 has an arc-shaped annular structure and a slot for placing cables is opened on its surface. In the initial state, the slot on the surface of the fixed ring disk 200 coincides with that on the rotating disk 300, and together with the central annular hole, they form a through semi-annular channel, which facilitates cable insertion and positioning.

[0029] The rotating disk 300 has an arc-shaped structure, with an ear piece 301 at one end, which is connected to the drive rod 110. The drive rod 110 is fixedly mounted on the surface of the fixed base 100 and is used to drive the rotating disk 300 to deflect relative to the fixed disk 200.

[0030] The surface of the fixed ring disk 200 is uniformly provided with radial grooves 210 to provide radial guidance; the surface of the rotating ring disk 300 is provided with arc grooves 310 to form a sliding fit with the sliding pin 430 during deflection.

[0031] The cutting blade assembly 400 includes a type I cutter 410 and a type II cutter 420, both arranged in a fan shape. The central angle of the type I cutter 410 is a right angle, and the central angle of the type II cutter 420 is an acute angle. There are two type I cutters 410 arranged opposite each other, and at least three type II cutters 420 arranged circumferentially spaced from the type I cutters 410. The type I cutters 410 and type II cutters 420 slide in contact with each other, together forming an annular cutting edge.

[0032] Both the Type I cutter 410 and the Type II cutter 420 are fixedly mounted with sliding pins 430. The sliding pins 430 pass through the radial groove 210 of the fixed ring disk 200 and are slidably sleeved inside the arc groove 310 of the rotating ring disk 300. Through this structure, as the rotating ring disk 300 deflects, the arc groove 310 drives the sliding pins 430 to slide along the radial groove 210, thereby driving the Type I cutter 410 and the Type II cutter 420 to move synchronously in a linear motion along the radial direction.

[0033] Through the above structural design, this utility model can achieve radial linear cutting of the cutter group 400 under the simple driving action of the drive rod 110, ensuring the uniformity and reliability of the cutting process, avoiding the problems of off-cut or damage caused by traditional manual or unidirectional cutting, thereby greatly improving the automation level and processing efficiency of cable production.

[0034] Working principle and usage process of this utility model: The cable is first placed into the slots on the surfaces of the fixed ring disk 200 and the rotating ring disk 300. In the initial state, the slots of the fixed ring disk 200 and the rotating ring disk 300 overlap to form a through semi-annular opening, which, together with the central annular hole, defines the cable placement channel, facilitating cable insertion and positioning.

[0035] The drive rod 110 is connected to the lug 301 at one end of the rotating disk 300. When the drive rod 110 is in operation, it causes the rotating disk 300 to deflect relative to the fixed disk 200.

[0036] In the cutter assembly 400, the Type I cutter 410 and Type II cutter 420 are synchronously slidably mounted in the radial groove 210 of the fixed ring disk 200 and the arc groove 310 of the rotating ring disk 300 via a sliding pin 430. That is, the sliding pin 430 passes through the radial groove 210 and is slidably sleeved on the inner side of the arc groove 310. As the rotating ring disk 300 deflects, the arc groove 310 drives the sliding pin 430 to move relative to it, thereby driving the cutter assembly 400 to make radial linear motion along the radial groove 210.

[0037] As the cutter assembly 400 gradually retracts radially, the I-shaped cutter 410 and the II-shaped cutter 420 approach and slide into contact in a circular direction, cutting the cable sheath and core material from different angles. When the cutter assembly 400 is fully retracted, the cable is radially cut, and the cutting action is completed.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0039] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
