Description

Technical Field

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

[0002] A cable is an electrical or signal transmission device, typically composed of several or groups of conductors, and characterized by internal current conduction and external insulation. Cables can be used to transmit electrical (magnetic) energy and information, realizing the conversion of electromagnetic energy. They are widely used in urban underground power grids, power plant lead-out lines, internal power supply in industrial and mining enterprises, and underwater power transmission lines across rivers and seas. There are many types of cables, including power cables, control cables, compensating cables, shielded cables, and high-temperature cables. They consist of single or multiple conductors and insulation layers, used to connect circuits and electrical appliances.

[0003] Existing cutting equipment (especially equipment that relies on traditional cutting methods) often struggles to achieve precise length control when dealing with small-sized cables with complex bending shapes (such as spirals or irregular bends). During the cutting process, the cutter is easily affected by factors such as deformation of the cable's bending parts and unstable positioning, which can cause the cut position to deviate from the preset value or the actual length of the cable after cutting to exceed the allowable tolerance, ultimately resulting in cutting failure and the production of dimensionally non-conforming products. Utility Model Content

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A cable cutting device includes a cutting mechanism, a wire support mechanism, and a straightening mechanism. The cutting mechanism includes a mounting plate and a cutting machine penetrating the top of the mounting plate. The wire support mechanism includes two sector gears movably mounted on the front side of the mounting plate via a rotating shaft, a shear bar I sleeved on the front end of the rotating shaft, a shear bar II movably connected to the top end of the shear bar I, a support plate connected between the two shear bars II, two wire straightening slides slidably connected to the top of the support plate, and a motor connected to the rear side of the mounting plate. The output shaft of the motor is connected to a rotating shaft near the left side of the mounting plate, and the two sector gears mesh with each other. The straightening mechanism includes a main drive rod sleeved on the rear end of the rotating shaft, an auxiliary drive rod parallel to the outside of the main drive rod and movably connected to the mounting plate, a pressure plate connected between the main drive rod and the auxiliary drive rod, and a wire straightening block connected to the bottom of the pressure plate.

[0007] By adopting the above technical solution,

[0008] In a preferred embodiment, the present invention can be further configured such that: the bottom of the mounting plate has multiple threaded holes arranged in a matrix.

[0009] In a preferred embodiment, the present invention can be further configured such that: a guide rod is fixedly connected to the rear side of the pallet, the guide rod slides through the rear side of the mounting plate, and the mounting plate has an opening suitable for the lifting and lowering of the guide rod.

[0029] 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.

[0030] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0031] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a wire cutting device for cable processing. Example

[0032] Combination Figure 1-6 As shown, the present invention provides a wire cutting device for cable processing, including a wire cutting mechanism 100, a wire supporting mechanism 200 and a straightening mechanism 300. The wire cutting mechanism 100 includes a mounting plate 110 and a wire cutting machine 120 passing through the top of the mounting plate 110.

[0033] The cable support mechanism 200 includes two sector gears 210 movably mounted on the front side of the mounting plate 110 via a rotating shaft, a shear bar 220 sleeved on the front end of the rotating shaft, a shear bar 230 movably connected to the top end of the shear bar 220, a support plate 240 connected between the two shear bars 230, two cable-strapping slides 250 slidably connected to the top of the support plate 240, and a motor 260 connected to the rear side of the mounting plate 110. The output shaft of the motor 260 is connected to a rotating shaft near the left side of the mounting plate 110, and the two sector gears 210 mesh with each other.

[0034] The straightening mechanism 300 includes a main drive rod 310 sleeved at the rear end of the rotating shaft, an auxiliary drive rod 320 parallel to the outside of the main drive rod 310 and movably connected to the mounting plate 110, a pressure plate 330 connected between the main drive rod 310 and the auxiliary drive rod 320, and a straightening block 340 connected to the bottom of the pressure plate 330.

[0035] Furthermore, the winding slide 250 is composed of a concave seat and a convex block. The convex block is integrally formed at the bottom of the concave seat. The top of the support plate 240 is provided with a slide track suitable for the sliding of the convex block. The length of the slide track is less than the length of the support plate 240. The shape design of the winding slide 250 ensures that it will not separate from the support plate 240 during sliding, and also better fits the shape of the wire, providing conditions for stably supporting the wire.

[0036] Furthermore, the bottom of the concave seat cavity and the bottom of the wire-straightening block 340 are both machined into arc surfaces with equal diameters. The shape design of the concave seat and the wire-straightening block 340 allows for a more secure clamping of the wire.

[0037] Furthermore, both pressure plates 330 are located on top of the support plate 240 and are vertically symmetrical about the vertical center plane of the support plate 240. The layout design of the pressure plates 330 provides conditions for the wire straightening block 340 to press the wire inside the wire straightening slide 250.

[0038] Furthermore, multiple inner steel bars 500 are installed at the bottom of the inner cavity of the wire-strapping slide 250, and multiple outer steel bars 600 are installed at the bottom of the wire-strapping block 340. The inner steel bars 500 and outer steel bars 600 work together to increase the friction force when the wire-strapping slide 250 and the wire-strapping block 340 clamp the wire, thereby improving the clamping strength. Example

[0039] Combination Figure 1-3 As shown, based on Embodiment 1, the mounting plate 110 has multiple threaded holes at its bottom, which are arranged in a matrix to facilitate the connection of the mounting plate 110 to the external plane. Example

[0040] Combination Figure 1 , 2 and Figure 4 As shown in the above embodiment, a guide rod frame 400 is fixedly connected to the rear side of the pallet 240. The guide rod frame 400 slides through the rear side of the mounting plate 110. An opening suitable for the lifting and lowering of the guide rod frame 400 is provided on the mounting plate 110. The guide rod frame 400 can guide the movement trajectory of the pallet 240 and improve the stability of the straightening wire operation.

[0041] The working principle and usage process of this utility model are as follows: First, the two cable-strapping slides 250 are gathered together, and the short and curved cable is placed between them. Then, the control motor 260 drives its output shaft to rotate counterclockwise, and the two sector gears 210 mesh with each other, driving the angle between shear bar 1 220 and shear bar 230 to increase, thereby causing the support plate 240 to rise in a straight line.

[0042] At the same time, the rotation of the sector gear 210 also drives the main transmission rod 310 to rotate, and then, under the guidance of the auxiliary transmission rod 320, pushes the pressure plate 330 to drive the cable straightening block 340 to move to the outside of the support plate 240. The cable straightening block 340 cooperates with the cable straightening slide 250 to clamp the two ends of the cable together.

[0043] Under the clamping pressure, the straightening block 340 drives the straightening slide 250 to move outward synchronously, straightening the bent cable. At this time, the wire cutter 120 can perform a clean cut operation, which effectively improves the yield of wire cutting.

[0044] 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.
