Description

Technical Field

[0001] The utility model relates to the technical field of ratio scissors, in particular to a bulletproof wire ratio scissors structure. Background Art

[0002] With the wide popularization and rapid development of electronic products, cables, as key components for connecting devices, play an important role in data transmission and power supply. In the production process of cables, the ratio cutting process is a crucial link, which involves precisely cutting multiple core wires in the cable to meet the requirements of different devices and applications. In the traditional cable ratio cutting process, flat mouth ratio scissors are mainly used for ratio cutting. When the traditional flat mouth ratio scissors are used to cut internal fillers such as bulletproof wires, they often cannot cut in place at one time and need secondary trimming. This not only reduces production efficiency but also increases production costs.

[0003] The prior art CN218109198U discloses a special-shaped core wire ratio scissors structure, which includes an upper ratio scissors blade and a lower ratio scissors blade, and the upper ratio scissors blade and the lower ratio scissors blade can move towards or away from each other. At the top end of the lower ratio scissors blade, there are a first cutting part and a second cutting part, and the width of the first cutting part is greater than that of the second cutting part. At the bottom end of the upper ratio scissors blade, there are a first cutter and a second cutter. The first cutter corresponds to the first cutting part, and the second cutter corresponds to the second cutting part. When ratio cutting the core wires, multiple core wires are placed in the corresponding cutting parts, and then the first cutter and the second cutter cooperate with the first cutting part and the second cutting part respectively to cut the multiple core wires. And because the width of the first cutting part is greater than that of the second cutting part, the lengths of the core wires cut by the first cutting part and the second cutting part will be different, so as to realize ratio cutting multiple core wires with different length dimensions at the same time, and finally improve the ratio cutting efficiency and ensure the ratio cutting quality.

[0004] However, this ratio scissors structure still cannot cut the internal fillers such as bulletproof wires of the cable in place at one time. Summary of the Utility Model

[0028] The preferred embodiments of the present utility model will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present utility model are shown in the drawings, it should be understood that the present utility model can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present utility model more thorough and complete, and to fully convey the scope of the present utility model to those skilled in the art.

[0029] In the existing production process of cables, the ratio cutting process is a crucial link, which involves precise cutting of multiple core wires in the cable to meet the requirements of different devices and applications. In the traditional cable ratio cutting process, flat mouth ratio cutting scissors are mainly used. When the traditional flat mouth ratio cutting scissors cut internal fillers such as bulletproof wires, they often cannot cut in place at one time and need secondary trimming. This not only reduces production efficiency but also increases production costs.

[0030] Based on this, the present application provides a bulletproof wire ratio cutting scissors structure.

[0031] Embodiment 1

[0032] See Figures 1-4 , this embodiment provides a bulletproof wire ratio cutting scissors structure, including an upper cutter seat 1 and a lower cutter seat 2 that can move towards or away from each other;

[0033] The upper cutter seat 1 includes an upper cutting piece 11. A first cutting surface 111 and a second cutting surface 112 are provided at the bottom of the upper cutting piece 11, and the first cutting surface 111 and the second cutting surface 112 are connected to each other; the first cutting surface 111 is located below the second cutting surface 112, and the angle α between the first cutting surface 111 and the vertical direction is greater than the angle β between the second cutting surface 112 and the vertical direction;

[0034] A cutting groove 24 is provided on the lower cutter seat 2, and the cutting groove 24 corresponds to the upper cutting piece 11. A plurality of limiting grooves 212 are provided at the top of one side of the cutting groove 24, and the plurality of limiting grooves 212 are arranged along the length direction of the cutting groove 24.

[0035] Specifically, the grooving 24 corresponds to the upper slicing blade 11 and is used to accommodate the cable to be sheared. During use, since the angles between the two cutting surfaces of the upper slicing blade 11 and the vertical direction are different, the two cutting surfaces can perform two shearing operations on the cable, thus ensuring effective cutting of the cable. When using this shearing structure, the operator places the cable to be sheared into the grooving 24 of the lower cutter base 2 and fixes the position of the cable through the limiting groove 212. Subsequently, the upper cutter base 1 and the lower cutter base 2 are driven to move towards each other, so that the upper slicing blade 11 contacts the cable and starts shearing. Since the upper slicing blade 11 has two cutting surfaces with different angles and the inclination angle of the first cutting surface 111 is larger, it can more effectively cut the cable and the bulletproof wire inside it. At the same time, the design of the limiting groove 212 prevents the cable from moving during the shearing process, ensuring the accuracy of shearing.

[0036] In the above bulletproof wire shearing structure, during use, the cable can be fixed through the limiting groove 212 to prevent the cable from moving during the shearing process, ensuring the accuracy and consistency of shearing. The upper slicing blade 11 including two cutting surfaces can effectively cut the cable and the bulletproof wire in the cable. The interaction between the limiting groove 212 and the upper slicing blade 11 enables this structure to shear the cable with internal fillers such as bulletproof wire in place at one time without secondary trimming. Since the number of shearing operations and subsequent processing steps are reduced, this shearing structure helps to improve production efficiency, and can also reduce the repetitive actions and physical consumption of the operator, thereby reducing the labor intensity.

[0037] Specifically, the upper cutter base 1 further includes a first gasket 12, and the first gasket 12 is arranged on one side of the upper slicing blade 11 and protrudes outward from one side of the upper slicing blade 11.

[0038] The first gasket 12 can play a role in limiting, preventing the upper cutter base 1 and the upper cutter base 1 from colliding with each other during the moving towards each other process, resulting in structural damage.

[0039] Further, the size of α is 40° - 45°; the size of β is 30° - 35°.

[0040] Preferably, α is 45°, and the size of β is 35°. The angle design of α and β enables the first cutting surface 111 and the second cutting surface 112 to effectively cut the cable and internal fillers such as bulletproof wire inside the cable during the shearing process, thereby improving the shearing efficiency.

[0041] More specifically, the lower cutting tool base 2 includes a limiting piece 21, a second gasket 22, and a lower cutting piece 23 that are connected in sequence. The second gasket 22 is located between the limiting piece 21 and the lower cutting piece 23, and the height of the top of the second gasket 22 is lower than the heights of the tops of the limiting piece 21 and the lower cutting piece 23. A cutting groove 24 is formed between the limiting piece 21 and the lower cutting piece 23. The cutting groove 24 is naturally formed among the limiting piece 21, the lower cutting piece 23, and the second gasket 22. In actual operation, the cable can be placed in the cutting groove 24 and cut by the cooperation of the first cutting piece and the lower cutting piece 23.

[0042] A plurality of limiting grooves 212 are provided at the top of the limiting piece 21.

[0043] The limiting grooves 212 are provided at the top of the limiting piece 21 and are used to limit the cable to be cut and sheared in the cutting groove 24, preventing the cable from moving disorderly during the cutting and shearing process, so as to ensure the effect of cutting and shearing and help improve the efficiency of cutting and shearing.

[0044] In a better implementation manner, the limiting grooves 212 are recessed downward from the top of the limiting piece 21, and along the length direction of the cutting groove 24, the limiting grooves 212 are connected end to end.

[0045] The width of the limiting groove 212 is 1 cm - 3 cm, and the depth of the limiting groove 212 is 0.3 cm - 0.5 cm.

[0046] The continuous limiting grooves 212 can effectively restrain the cable, which is beneficial to the limitation of the cable. The specific dimensions of the limiting grooves 212 are that the width is controlled between 1 cm and 3 cm, and the depth is between 0.3 cm and 0.5 cm. Such a dimension range can not only ensure the stable limitation of the cable, but also not damage the cable. At the same time, it is also convenient for the operator to quickly and accurately place the cable during the cutting and shearing process.

[0047] Furthermore, an avoidance groove 211 is provided on the limiting piece 21. The avoidance groove 211 is located on one side of the cutting groove 24, and the length direction of the avoidance groove 211 is the same as the length direction of the cutting groove 24.

[0048] An avoidance inclined surface 2111 is provided at the top of the avoidance groove 211, and the included angle δ between the avoidance inclined surface 2111 and the vertical direction is 3° - 5°. The design of the avoidance groove 211, on the one hand, saves the material used in the structure of this cutting and shearing tool; on the other hand, it makes the position of the cutting groove 24 have enough space to accommodate the cable. Moreover, avoiding the space on one side of the cutting groove 24 can prevent the cable from shifting due to the extrusion of the internal filler of the cable during the cutting and shearing process, resulting in the phenomenon that the cutting and shearing position is not neat.

[0049] In a better embodiment, a third cutting surface 231 is provided at the top of the lower slicing member 23, and the third cutting surface 231 is disposed close to the cutting groove 24.

[0050] An avoidance space 232 is further provided on the lower slicing member 23, and the avoidance space 232 penetrates through the cutting groove 24 along the width direction of the cutting groove 24.

[0051] This avoidance space 232 can save the material of the entire cable-shearing structure, thereby reducing the manufacturing cost of this structure. The third cutting surface 231 cooperates with the first cutting surface 111 and the second cutting surface 112 to effectively shear the cable.

[0052] Embodiment 2

[0053] This embodiment provides a cable-shearing device, which includes a main body, and a workbench is provided on the main body. It further includes the bulletproof wire cable-shearing structure as described above.

[0054] Specifically, the lower cutter base 2 is fixed on the workbench. A driving device is further provided above the workbench, and the upper cutter base 1 is fixed on the driving device. The driving device drives the upper cutter base 1 to move up and down, so as to perform cable-shearing on the cable placed on the lower cutter base 2.

[0055] During the cable-shearing process, first place the cable in the cutting groove 24 of the lower cutter base 2, and use the limiting groove 212 to limit the cable. Then, start the driving device to make the upper cutter base 1 move downward, cooperate with the lower cutter base 2, and perform precise cable-shearing on the cable. This design not only improves the accuracy and efficiency of cable-shearing, but also greatly reduces the operation difficulty, making the cable-shearing work easier and faster.

[0056] For the sake of description, spatial relative terms, such as "above...", "over...", "on the upper surface of...", "upper...", etc., can be used here to describe the spatial position relationship between one device or feature and other devices or features as shown in the figure. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation of the device described in the figure. For example, if the device in the figure is inverted, the device described as "above other devices or structures" or "over other devices or structures" will be positioned as "below other devices or structures" or "under other devices or structures" afterwards. Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding explanations are made for the spatial relative descriptions used here.

[0057] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Without additional declaration, the above terms have no special meaning, and therefore should not be construed as a limitation on the protection scope of this application.

[0058] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
