Description

Technical Field

[0001] This utility model relates to the field of wire and cable manufacturing technology, specifically, it demonstrates a cutting mechanism for cable processing and production. Background Technology

[0002] Cables are a general term encompassing optical fibers, electrical cables, and similar items. They have numerous uses, primarily for control installations, equipment connections, and power transmission, making them a common and indispensable consumable in daily life. In routine cable manufacturing, the quality of cable cutting directly affects the conductivity of components. Therefore, ensuring the flatness of the cut cable and that the cut surface is perpendicular to the cable becomes a crucial indicator of cable yield.

[0003] For example, Chinese patent CN221414829U discloses a wire cutting device, which uses a cutting blade in conjunction with a motor, the motor driving the cutting blade in conjunction with the motor, and a slider in conjunction with a pulley, the slider moving to cut the wire and the pulley moving to cut the wire, thereby achieving the cutting effect.

[0004] However, when the cutting blade of the device cuts, it exerts strong local pressure on the cable cutting point, while the area around the cutting point is not restricted. The outer strands of the cable are squeezed and deformed, and the cutting surface is tilted, resulting in deformation of the cutting surface. Utility Model Content

[0005] The purpose of this invention is to provide a cutting mechanism for cable processing and production, which has a simple and practical structure and good cutting effect.

[0006] The technical solution is as follows:

[0007] A cutting mechanism for cable processing and production includes a frame, on which:

[0008] The upper cutter and the drive structure that drives the upper cutter to move up and down;

[0009] The lower cutter is located below the upper cutter. The cutting edge of the lower cutter is staggered with the cutting edge of the upper cutter. The interior of the lower cutter has a through-hole for wire exiting.

[0010] The wire feed shaft is hollow inside and has a wire outlet channel for the cable to pass through, and the wire outlet channel is connected to the wire outlet hole.

[0011] The cable feeding structure is located at the beginning of the cable feeding shaft, so that the cable flows into the cable outlet channel and cable outlet hole in sequence along the direction of the cable feeding shaft and is exposed to the outside from the cutting edge of the lower cutter.

[0012] In addition, the above embodiments of this utility model may also have the following additional technical features:

[0013] According to one embodiment of the present invention, a wire support seat is further provided outside the lower cutter, the upper surface of the wire support seat being flush with the lower cut surface of the cable outlet channel. When the cable is exposed outward from the cable outlet channel of the lower cutter (the exposed portion is the section to be cut), the wire support seat provides an additional horizontal support platform.

[0014] In one embodiment, a wire clamping head and a lifting cylinder for driving the wire clamping head to move up and down are provided above the wire holder. The head of the wire clamping head is provided with an arc-shaped limiting groove. This fixes the position of the cable on the wire holder, ensuring that the wire is fixed during cutting.

[0015] According to one embodiment of the present invention, the driving structure includes:

[0016] The main rod, the middle part of which is hinged to the frame via a hinge seat;

[0017] A connecting rod, one end of which is hinged to the main rod;

[0018] A movable slide body has a slide seat movably mounted on it by a snap-fit ​​mechanism. The slide seat is mounted on the frame. One end of the movable slide body is hinged to a connecting rod, and the other end is connected to the upper cutter.

[0019] A drive cylinder is mounted on the frame, and its output shaft is hinged to the other end of the main rod.

[0020] The sliding block on the movable slide works in conjunction with the frame to provide cushioning and guidance, ensuring a smooth and uninterrupted downward pressing process for the upper cutter.

[0021] In one embodiment, the end of the upper cutter is constructed as an inclined surface, with an arched groove recessed inward on the inclined surface. The center line of the arched groove coincides with the center line of the wire outlet channel. This avoids outward deformation of the wire strands caused by direct hard contact between the upper cutter and the wire.

[0022] According to one embodiment of the present invention, the wire feeding structure includes:

[0023] The cable feeder has a pair of mirrored side plates with opposing through holes that communicate with the cable outlet channel.

[0024] The wire feeding groove is recessed along the length of the wire feeding base and located between a pair of side plates.

[0025] The wire feeding roller is located directly above the wire groove and is spaced apart from the wire groove. The rolling direction of the wire feeding roller is parallel to the extension direction of the wire groove.

[0026] The wire feeding motor has its output end connected to the wire feeding roller.

[0027] The cable feed motor drives the rollers to rotate, and the cable is gradually fed in by friction, ensuring stable delivery.

[0028] In one embodiment, the center lines of the through hole, the wire rolling groove, the wire exit groove, and the wire exit hole are located on the same straight line. This ensures that the cable is free from any bending or twisting from the wire feeding inlet to the cutting outlet, protecting the original shape of the cable.

[0029] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0030] 1. The blades of the upper and lower cutters are staggered, forming a shearing mechanism similar to scissors, rather than single-point compression. During cutting, the upper cutter presses down and the lower cutter generates staggered shearing forces, so that the cutting force is evenly distributed throughout the cutting point, rather than concentrated in a single position, ensuring a flat and highly perpendicular cut surface.

[0031] 2. The lower cutter has a through-hole for cable exiting from the front and back. The cable enters the exit hole from the cable feed shaft and protrudes outward at one end. The exit hole acts as a built-in guide structure for the cutting point, which constrains the cable circumferentially during the cutting process, similar to the effect of a "conduit". This prevents the part of the cable around the cutting point from bending or shifting due to force, which keeps the cable in a straight position and keeps the cutting point in the center, thus avoiding skewed cutting surfaces.

[0032] 3. The cable outlet channel of the cable feeding shaft is connected to the cable outlet channel of the lower cutter. Together with the cable feeding structure, the cable is driven to flow in. This realizes a straight path for the cable from feeding to cutting, avoiding bending or instability caused by manual feeding.

[0033] 4. The wire feeding, guiding and cutting are integrated into one unit. The vertical movement of the upper cutter and the fixed support of the lower cutter form a dynamic cutting system. Compared with the existing technology, the cutting process is more stable and the vibration is smaller. Attached Figure Description

Detailed Implementation

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0040] Example 1

[0041] This utility model embodiment proposes a cutting mechanism for cable processing and production, including a frame 1, and an upper cutter 2, a drive structure 3, a lower cutter 4, a wire feeding shaft 5, and a wire feeding structure 6 disposed on the frame 1.

[0042] See Figure 2 As shown, the upper cutter 2 and the lower cutter 4 are arranged vertically opposite each other. The driving structure 3 can drive the upper cutter 2 to move up and down relative to the lower cutter 4. During the movement of the upper cutter 2, the cutting surface of the lower cutter 4 and the cutting edge of the upper cutter 2 can form an alternating vertical arrangement. A wire outlet channel 41 that runs through the front and back is provided inside the lower cutter 4. The wire outlet channel 41 is cylindrical in shape, and both ends of the wire outlet channel 41 can be exposed outward from the side of the lower cutter 4.

[0043] See Figure 1 As shown, the wire feeding shaft 5 is horizontally arranged, hollow inside and has a wire outlet channel 51 for cable flow. That is to say, the wire outlet channel 51 is opened along the length of the wire feeding shaft 5, and it is also cylindrical. The wire feeding shaft 5 is distributed on one side of the lower cutter 4, so that the wire outlet channel 51 is connected to the wire outlet hole 41, forming a route for cable travel. The wire feeding structure 6 is set at the beginning of the wire feeding shaft 5. The cable enters the wire outlet channel 51 of the wire feeding shaft 5 through the wire feeding structure 6, and finally the cable flows into the wire outlet channel 51 and the wire outlet hole 41 in sequence along the direction of the wire feeding shaft 5 and is exposed outward from the cutting edge of the lower cutter 4. The exposed part is the section to be cut.

[0044] During cutting, the upper cutter presses down and the lower cutter generates staggered shearing forces, ensuring that the cutting force is evenly distributed across the entire cutting point rather than concentrated in a single location. This guarantees a flat and highly perpendicular cut surface. The lower cutter has a through-hole for cable exiting from the front and back. The cable enters the exit hole from the cable feed shaft's exit groove, with a section protruding outwards. The exit hole acts as a built-in guide structure at the cutting point, providing circumferential constraint on the cable during the cutting process, similar to a "conduit" effect. This prevents the portion of the cable around the cutting point from bending or shifting due to force, keeping the cable straight and ensuring that the cutting point remains centered, thus avoiding a skewed cut surface.

[0045] See Figure 1 As shown, the drive structure 3 comprises a main rod 31, a connecting rod 33, a movable slide body 34, a slide seat 35, and a drive cylinder component 36, designed as follows: The main rod 31 is hinged to the frame 1 at its middle position via a hinge seat 32, forming a seesaw-like structure. The end of the main rod 31 is hinged to a connecting rod 33, and the beginning of the main rod 31 is hinged to the drive output shaft end of a drive cylinder component 36. The drive cylinder component 36 is fixed on the frame 1, and the drive cylinder component 36 drives the main rod 31 to swing up and down with its middle position as the fulcrum. The other end of the connecting rod 33 is hinged to a movable slide body 34, and the lower end of the movable slide body 34 is connected to the cutter 2. The slide seat 35 is movably mounted on the movable slide body 34 in a snap-fit ​​manner, and the slide seat 35 is fixed on the frame 1.

[0046] The drive structure employs a hinged design of connecting rods and main rods, converting the linear motion of the drive cylinder into the precise vertical motion of the upper cutter. The sliding block on the movable slide works in conjunction with the frame, providing cushioning and guidance, ensuring a smooth and uninterrupted downward movement of the upper cutter and preventing micro-deformation or tilted cutting caused by uneven cable stress. The lever principle of the main rod amplifies the force of the drive cylinder, while the connecting rod and movable slide achieve a combined force-amplifying and guiding effect. This allows the upper cutter to apply uniform cutting force with minimal energy consumption. Simultaneously, the locking design of the sliding block allows for fine-tuning of the upper cutter position, ensuring the blade is always staggered and aligned with the lower cutter, extending tool life.

[0047] See Figure 2 As shown, the end of the upper cutter 2 has an inclined surface with an inwardly recessed arched groove 21. The centerline of the arched groove 21 coincides with the centerline of the cable outlet 41. The inclined blade design helps the upper cutter easily cut into the cable, reducing initial resistance and making the cutting process smooth and efficient. Moreover, the inwardly recessed arched groove at the end of the upper cutter provides a space to accommodate the cable at the moment of cutting, allowing the cable tip to slightly sink into the groove, avoiding the outward expansion deformation of the wire strands caused by direct hard contact of the upper cutter. The arched design of the groove (such as a semi-circle) matches the cable cross-section, evenly distributing the cutting force and protecting the integrity of the sheath or insulation layer.

[0048] See Figure 3 As shown, the wire feeding structure 6 comprises a wire feeding base 61, a wire rolling groove 64, a wire feeding roller 65, and a wire feeding motor 66, designed as follows: The wire feeding base 61 is horizontally arranged, and its top surface has a pair of mirrored side plates 62. Opposite through holes 63 are opened on the two side plates 62, and the two through holes 63 communicate with the wire outlet channel 51. The wire rolling groove 64 is recessed along the length of the wire feeding base 61 on its top surface. The longitudinal section of the wire rolling groove 64 is semi-arc-shaped, and the wire rolling groove 64 is located between the pair of side plates 62. It is worth noting that the through holes 63 and the wire rolling groove 64... The center lines of the cable outlet channel 51 and the cable outlet hole 41 must be aligned to ensure that the cable is fed in a straight line from the cable inlet to the cutting outlet without any bends or twists. The cable feeding roller 65 is located directly above the cable rolling groove 64 and there is a gap between it and the bottom of the cable rolling groove 64. The rolling direction of the cable feeding roller 65 is parallel to the extension direction of the cable rolling groove 64. The cable feeding motor 66 is mounted on the cable feeding base 61 and its output end is connected to the cable feeding roller 65. The cable feeding motor 66 drives the cable feeding roller 65 to rotate, and the cable is gradually fed by friction.

[0049] There is a gap between the wire feeding roller and the wire rolling groove to form an adjustable clamping gap, which can accommodate cables of different diameters. The wire feeding motor drives the roller to rotate and push the cable forward by friction (not compression), avoiding direct compression by the roller to prevent deformation of the cable surface or wear of the sheath. The wire rolling groove acts as a support structure to keep the cable transported horizontally.

[0050] Example 2

[0051] The design scheme of this embodiment is based on the technical solution of embodiment 1.

[0052] See Figure 4 As shown, a cable holder 7 is provided on the outside of the lower cutter 4. The cable holder 7 is parallel to the lower cutter 4 and has a certain distance between them. The upper surface of the cable holder 7 is flush with the lower cut surface of the cable outlet 41. When the cable is exposed outward from the cable outlet of the lower cutter (the exposed part is the section to be cut), the cable holder provides an additional horizontal support platform, which means that the end of the cable is naturally laid flat on the cable holder before cutting, avoiding drooping or bending caused by gravity, ensuring that the entire cable section remains horizontal at the moment of cutting, and reducing the offset or deformation of the cutting point caused by suspension.

[0053] In other possible implementations, a wire clamping head 8 and a lifting cylinder 9 that drives the wire clamping head 8 to move up and down are provided above the wire holder 7. The head end of the wire clamping head 8 is provided with an arc-shaped limiting groove 81. Before cutting, the lifting cylinder drives the wire clamping head to press down, and its arc-shaped limiting groove fits the outer surface of the cable to form a non-destructive clamping. This fixes the position of the cable on the wire holder, prevents the section to be cut from shifting during cutting, ensures that the wire is fixed during cutting, and improves the perpendicularity and consistency of the cut end face.

[0054] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
