Description

Technical Field

[0001] The invention relates to the technical field of cable ring cutting, in particular to a ring cutting device and a ring cutting method for cable processing. Background Art

[0002] In today's power engineering, electrical equipment manufacturing, and various fields involving the use and installation of cables, cables are the key carriers of power transmission and signal conduction, and their processing is crucial. Whether it is the laying of new power lines or the maintenance and upgrading of old lines, it is inseparable from the precise operation of cables to meet the use requirements under different working conditions.

[0003] As for the basic and key processing procedure of cable ring cutting, the traditional manual ring cutting method has long dominated. Workers hold knives and perform ring cutting operations on the cable sheath based on experience and manual skills. However, this method has many disadvantages. On the one hand, it is difficult to ensure the uniformity of wrist force and the consistency of the knife cutting angle each time the manual operation is carried out, which can easily lead to uneven incisions and different depths. This not only affects the appearance quality of the cable after ring cutting, but is also likely to cause premature damage to the cable sheath due to uneven stress distribution at the incision during subsequent use, reducing the service life of the cable, and even affecting the stability of power transmission, bringing potential risks to the power system. On the other hand, when facing cables of different specifications and sizes, traditional manual ring cutting lacks effective adaptive adjustment means. Workers often need to stop their work and spend extra time to find knives suitable for the new cable size, or carefully adjust the cutting force and depth by feeling. The whole process is cumbersome and inefficient, and greatly consumes manpower and time costs. In addition, in order to further process the cable later, such as stripping the insulation sleeve, the cable after traditional ring cutting is also quite difficult to handle. Since there is no auxiliary structure to prepare for the removal of the insulating sleeve during ring cutting, workers can only rely on brute force or sharp tools to forcibly tear off the insulating sleeve. This is not only a huge workload, but also very easy to damage the battery core, causing the cable to be scrapped and increasing production costs. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a ring cutting device and a ring cutting method for cable processing, which solves the problems of uneven stress distribution at the incision, causing premature damage to the cable sheath and reducing the service life of the cable. When facing cables of different specifications and sizes, traditional manual ring cutting lacks effective adaptive adjustment means and forcibly tears off the insulating sleeve, resulting in a huge workload, and is also very likely to damage the battery core, causing the cable to be scrapped and increasing production costs.

[0005] To achieve the above purpose, the present invention is implemented through the following technical scheme: a ring cutting device for cable processing, comprising: A sleeve, an annular chute is provided on the outer wall of the rear end of the sleeve, a slider is slidably connected inside the annular chute, a cutting ring blade is slidably connected to the inner wall of the slider, a T-shaped linkage plate is fixedly connected to the outer wall of the cutting ring blade, and a handle is provided on the top side of the T-shaped linkage plate for controlling the sliding of the cutting ring blade inside the slider; A fixed shaft, the fixed shaft is fixedly connected to the outer wall of the sleeve, a sliding rod is fixedly connected to the middle end of the fixed shaft, and a fixing component is provided on the outer wall of the sliding rod for fixing the cable to be cut, and a rotating disk is rotatably connected to the front side of the fixed shaft; A fixed rod, the fixed rod is slidably connected to the rear end of the T-shaped linkage plate, a support plate is fixedly connected to the end of the fixed rod away from the T-shaped linkage plate, a stripping component is provided on the outer wall of the support plate for stripping the cable insulating sleeve after cutting, and the rear side of the slider is connected to the support plate through a support component for controlling the lifting of the support plate.

[0006] Preferably, the fixing component includes a fixing plate slidably connected to the outer wall of the sliding rod, an upper arc-shaped fixing block is fixedly connected to the outer wall of the upper fixing plate, a lower arc-shaped fixing block is fixedly connected to the outer wall of the lower fixing plate, and a dial is fixedly connected to the front side of the fixing plate.

[0007] Preferably, the stripping component includes an upper arc-shaped card fixedly connected to the outer wall of the upper support plate, a lower arc-shaped card is fixedly connected to the outer wall of the lower support plate, and support shafts are provided on the inner walls of the upper arc-shaped card and the lower arc-shaped card.

[0008] Preferably, the handle includes a mounting block fixedly connected to the outer wall of the T-shaped linkage plate, and a grip is fixedly connected to the outer wall of the mounting block.

[0009] Preferably, the support component includes a support shaft fixedly connected to the rear side of the slider, a support rod is fixedly connected to the rear end of the support shaft, and the support plate is slidably connected to the outer wall of the support rod.

[0010] Preferably, a return spring is provided on the outer wall of the sliding rod for driving the reset of the fixing plate.

[0011] Preferably, a compression spring is provided on the outer wall of the fixed rod for driving the reset of the support plate.

[0012] Preferably, the cutting ring blade is arranged at the rear side of the sleeve for cutting the cable in a circular shape.

[0013] A composite plating method includes the following steps; Step 1: First, rotate the rotating disk so that the through hole opened on the outer wall of the rotating disk moves to the front side of the upper arc-shaped fixing block, and then pass the cable through the through hole on the outer wall of the rotating disk, the inner wall of the sleeve and the bottom side of the upper arc-shaped card in sequence; Step 2: Then, drive the fixed plate to slide on the outer wall of the sliding rod by toggling the dial to compress the return spring, so that the upper arc-shaped fixing block and the lower arc-shaped fixing block fix the cable. Then, hold the grip piece to drive the T-shaped linkage plate and the cutting ring blade to slide inside the slider, and drive the upper arc-shaped card and the lower arc-shaped card to press on the outer wall of the cable. Step 3: Then, continue to press down the grip piece to drive the T-shaped linkage plate and the cutting ring blade to continue sliding inside the slider, and insert the cutting ring blade into the cable until it reaches an appropriate depth. Step 4: Then, continue to press the dial to clamp and fix the cable through the upper arc-shaped fixing block and the lower arc-shaped fixing block. Then, control the slider to slide on the outer wall of the sleeve to drive the cutting ring blade to cut the cable inside the sleeve. Step 5: After the cable is cut, first release the dial to release the clamping and fixing of the cable by the upper arc-shaped fixing block and the lower arc-shaped fixing block. Then, continue to hold the dial and pull the sleeve and the dial to separate the cut cable outer skin from the outer wall of the cable core.

[0014] Preferably, when the dial is continuously pressed in Step 3, when the upper arc-shaped card and the lower arc-shaped card press on the outer wall of the cable, they will not continue to clamp the outer wall of the cable as the dial is pressed down. The T-shaped linkage plate will slide between the fixed plate to compress the compression spring, and a shallow groove will be cut on the outer wall of the cable.

[0015] The present invention provides a cutting ring device and a cutting ring method for cable processing. It has the following beneficial effects: 1. Through the cooperation of structures such as the annular chute, the slider, the cutting ring blade, and the T-shaped linkage plate, the present invention can achieve precise cutting of the cable. When the cutting ring blade slides inside the slider, it can perform uniform and stable cutting on the cable at the rear of the sleeve, avoiding problems such as uneven cut and inconsistent depth that may occur in traditional manual cutting, ensuring the cutting quality. At the same time, the through-hole design on the outer wall of the rotating disc enables cables of different sizes to be quickly inserted into the through-hole, and then pass through the inner wall of the sleeve and the space between the upper arc-shaped card and the lower arc-shaped card in sequence, conveniently and quickly adapting to cables of different specifications without frequently replacing equipment or adjusting the device, greatly improving the efficiency of cable processing and saving time and labor costs.

[0016] 2. The present invention enables the staff to easily hold the grip piece manually through the setting of the grip piece, driving the T-shaped linkage plate and the cutting ring blade to slide inside the slider. The operation is simple and intuitive, without complex mechanical operations or electrical controls, reducing the operation difficulty. Even non-professionals can quickly get started. The upper arc-shaped fixing block and the lower arc-shaped fixing block slide on the outer wall of the sliding rod through the fixing plate, and cooperate with the pressing of the dial piece to firmly clamp the cable. The design of the return spring can automatically release the clamping and fixing when the dial piece is released. This fixing method not only ensures the stability of the cable during the cutting process, avoiding the influence of cable shaking on the cutting effect, but also facilitates the quick loading and unloading of the cable, improving the work efficiency.

[0017] 3. The present invention cuts a shallow groove on the outer wall of the cable through the upper arc-shaped card and the lower arc-shaped card via the support shaft, which combines with the groove after the cable is cut by the cutting ring blade, making it easier for the cut cable insulating sleeve to be detached from the outer wall of the battery core, reducing the workload and difficulty of manual stripping of the insulating sleeve, and improving the overall efficiency of cable processing. The support shaft is fixedly connected to the outer wall of the slider, and the support rod is fixedly connected to the rear end of the support shaft, providing stable support for the sliding of the support plate, the upper arc-shaped card and the lower arc-shaped card, ensuring the stability of the entire device during the cutting and the detachment of the insulating sleeve.
