Description

Technical Field

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0033] In the embodiments of the present invention, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium; internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.

[0034] In one embodiment of the present invention, according to Figure 1-3 As shown, a wire shearing device includes a shearing assembly; the shearing assembly includes a first blade 100, a second blade 200 and a driving device 300; the first blade 100 and the second blade 200 partially overlap with each other to form an overlapping position 400, and the driving device 300 is provided with a limiting shaft 310, and the first blade 100 and the second blade 200 are rotatably connected to one end of the limiting shaft 310 with the overlapping position 400 as the axis. A first shearing portion 110 is provided at one end of the first blade 100, and a first driving portion 120 is provided at the other end; a second shearing portion 210 is provided at one end of the second blade 200, and a second driving portion 220 is provided at the other end, characterized in that both the first shearing portion 110 and the second shearing portion 210 are provided with an arc-shaped shearing notch 500, and the driving device 300 is respectively connected to and drives the first driving portion 120 and the second driving portion 220, so that the first blade 100 and the second blade 200 rotate with the overlapping position 400 as the axis to shear the wire.

[0035] Specifically, by providing an arc-shaped cutting cut 500 on the first cutting portion 110 and the second cutting portion 210, when cutting the wire, the shearing force is uniformly contracted inward around the wire, so that the wire after cutting will not have obvious sharp protrusions at the cutting cut, and the cutting cut is relatively smooth, and will not scratch the user during subsequent use and processing.

[0036] In another embodiment of the present invention, according to Figure 1 and 2 As shown, a first avoidance position 311 is provided at one end of the limit shaft 310, and the overlapping position 400 is provided in the first avoidance position 311. A first limit pin 312 passes through the limit shaft 310 and the overlapping position 400 to rotationally connect the first blade 100 and the second blade 200 to one end of the limit shaft 310.

[0037] Specifically, by providing the first avoidance position 311 and then arranging the overlapping position 400 within the first avoidance position 311, the connection can be made more secure, and the first blade 100 and the second blade 200 can rotate with the first limiting pin 312 as the axis. When the driving device 300 drives the first driving part 120 and the second driving part 220, the first blade 100 and the second blade 200 can open and close to perform shearing. It is understandable that when the first driving part 120 and the second driving part 220 are fixed, the driving device 300 can also drive the limiting shaft 310 to achieve the above-mentioned opening and closing function.

[0038] In another embodiment of the present invention, according to Figure 1 and 2 As shown, the drive device 300 includes a cylinder 320 and a base plate 330; the cylinder 320 includes a piston rod 321 and a cylinder body 322; the base plate 330 is fixedly connected to the cylinder body 322, and a limit shaft 310 passes through the base plate 330 and is connected to the piston rod 321. The piston rod 321 has one end connected to the limit shaft 310 and the other end connected to a fixed plate 340. The base plate 330 is connected to the first drive unit 120 and the second drive unit 220 via a first connecting shaft 130 and a second connecting shaft 230, respectively. The cylinder body 322 and the base plate 330 move on the piston rod 321, thereby driving the first drive unit 120 and the second drive unit 220 to move, causing the first blade 100 and the second blade 200 to rotate around the overlapping position 400 as the axis to shear the wire. The base plate 330 is provided with a through hole 380. One end of the limit shaft 310 is connected to the overlapping position 400, and the other end passes through the through hole 380 and is connected to the piston rod 321.

[0039] Specifically, the fixed plate 340 and the piston rod 321 are fixed, and the cylinder body 322 and the bottom plate 330 move up and down, thereby driving the first connecting shaft 130 and the second connecting shaft 230 to move up and down, and then driving the first driving part 120 and the second driving part 220, so that the first blade 100 and the second blade 200 rotate around the overlapping position 400 as the axis to open and close for shearing. It can be understood that the overlapping position 400 as the axis and the first limit pin 312 as the axis are the same position.

[0040] In another embodiment of the present invention, according to Figure 1 and 2As shown, both the first connecting shaft 130 and the second connecting shaft 230 are provided with a second avoidance position 131, and the first driving portion 120 and the second driving portion 220 are respectively provided in the two second avoidance positions 131. A second limiting pin 350 is provided through the first connecting shaft 130 and the first driving portion 120, and a third limiting pin 360 is provided through the second connecting shaft 230 and the second driving portion 220. The first driving portion 120 is provided with a first slotted hole 121, and the second driving portion 220 is provided with a second slotted hole 221. The second limiting pin 350 passes through the first connecting shaft 130 and the first slotted hole 121, thereby connecting the first connecting shaft 130 to the first driving portion 120. The third limiting pin 360 passes through the second connecting shaft 230 and the second slotted hole 221, thereby connecting the second connecting shaft 230 to the second driving portion 220.

[0041] Specifically, by setting the first slot hole 121 and the second slot hole 221, some space can be given to drive the first blade 100 and the second blade 200 to rotate during the up and down movement of the first connecting shaft 130 and the second connecting shaft 230. If the first slot hole 121 and the second slot hole 221 are not set, the first connecting shaft 130 and the second connecting shaft 230 will be stuck when driving the first driving part 120 and the second driving part 220, and the opening and closing rotation of the first blade 100 and the second blade 200 will not be achieved.

[0042] In another embodiment of the present invention, according to Figure 1 and 2 As shown, a guide rod 370 is further provided on the bottom plate 330 , one end of the guide rod 370 is connected to the bottom plate 330 , and the other end is passed through the fixing plate 340 .

[0043] Specifically, the guide rod 370 plays a guiding role, increasing the stability of the cylinder body 322 moving up and down.

[0044] In another embodiment of the present invention, Figure 3As shown, the apparatus also includes a bracket 600, on which is mounted a moving device 700. The moving device 700 is connected to and drives the shearing assembly up and down. The moving device 700 includes a slider 710 and a guide rail 720. The slider 710 slides relative to the guide rail 720 and is fixedly connected to the bracket 600. A driving assembly 730 drives the guide rail 720 up and down on the slider 710, thereby driving the shearing assembly up and down. The guide rail 720 is connected to the fixed plate 340. The driving assembly 730 drives the fixed plate 340 up and down, thereby driving the first blade 100 and the second blade 200 to move up and down to cut the wire material. Specifically, the moving device 700 is used to drive the shearing assembly up and down to cut the wire material. The moving device 700 utilizes a slider 710 and a guide rail 720, which slide relative to each other. In this design, the slider 710 is fixed to enable the guide rail 720 to move, while the guide rail 720 can also be fixed to enable the slider 710 to move, both of which can achieve the aforementioned functions. The driving assembly 730 is disposed on the bracket 600 . The driving assembly 730 drives the slider 710 and the guide rail 720 to slide relative to each other, thereby achieving the purpose of moving the shearing assembly up and down to shear the wire.

[0045] It is understandable that the driving assembly 730 can be a cylinder, a motor, a screw, an electric push rod, or other devices.

[0046] The above description further details the present invention in conjunction with specific preferred embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. A person skilled in the art of the present invention will appreciate that its architecture is flexible and adaptable, allowing for the development of a series of products without departing from the present invention's concept. Simple deductions or substitutions should be considered within the scope of patent protection for the present invention as defined by the submitted claims.
