DETAILED DESCRIPTION
[0018] The present invention is further described clearly and completely below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0019] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.
[0020] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values of the parts and steps described in these embodiments do not limit the scope of the utility model. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in one drawing, it does not need to be further discussed in subsequent drawings.
[0021] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.
[0022] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0023] 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. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.
[0024] The utility model discloses a wire shearing device, such as Figure 1-3 As shown, it includes a base 1, and a transmission mechanism and a shearing mechanism arranged on the base 1, the transmission mechanism includes a transmission shaft 2 and a clamping shaft 3 arranged above the transmission shaft 2 and adjustable up and down. Specifically, the surface of the transmission shaft 2 is provided with a knurling design to enhance friction, and the transmission shaft 2 and the clamping shaft 3 are both installed on the base 1 through a bearing seat 7. One end of the transmission shaft 2 is connected to a motor 8 and can realize transmission under the drive of the motor 8. A pressure block 9, a clamping spring 10 and a spring pressure plate 11 are provided above the left and right ends of the clamping shaft 3. A gap is provided between the transmission shaft 2 and the clamping shaft 3 for the steel wire 4 to pass through. When in use, the clamping spring 10 is squeezed by the spring pressure plate 11, so that the clamping spring 10 squeezes the clamping shaft 3 downward through the pressure block 9, thereby clamping the steel wire 4 between the clamping shaft 3 and the transmission shaft 2, increasing friction and facilitating the transmission of the steel wire 4 to the shearing mechanism. Furthermore, a wire guide block 12 is provided on the side of the transmission mechanism away from the shearing mechanism, and a guide hole 13 is provided on the wire guide block 12 which matches the gap between the transmission shaft 2 and the clamping shaft 3.
[0025] The shearing mechanism is arranged on one side of the transmission mechanism, including a wire support plate 5 and a shearing knife 6 arranged above the wire support plate 5. Specifically, a wire guide groove Ⅰ14 is provided above the wire support plate 5, and a bell mouth 15 extending outward is provided at the end of the wire guide groove Ⅰ14. A support plate spring 16 is connected to the bottom of the wire support plate 5. The shearing knife 6 is connected to a driving member for driving it to move downward to achieve shearing. The driving member can be a cylinder, a hydraulic cylinder or a punching machine. A wire guide groove Ⅱ17 is provided at the bottom of the shearing knife 6, and the end edge of the wire guide groove Ⅱ17 is a shearing blade.
[0026] When the utility model is used, the steel wire 4 enters between the transmission shaft 2 and the clamping shaft 3 through the guide hole 13, and the steel wire of the set length is sent into the shearing mechanism under the rotation of the transmission shaft 2. When the shearing knife 6 cuts down, the steel wire supporting plate 5 moves down with the cutting of the shearing knife 6. When the steel wire 4 is cut, the shearing knife 6 will bounce the steel wire supporting plate 5 and the shearing knife 6 back to the original position together through the elastic force of the supporting plate spring 16. After the steel wire is cut, it will naturally fall along the bell mouth 15 due to gravity, and no further processing is required. The shearing of one steel wire is completed, and then the transmission shaft 2 rotates again to send the steel wire to the set length, and then the next cutting is carried out, and this is repeated.
[0027] To sum up, the utility model provides a wire shearing device with simple structure, stability and reliability, low processing cost, high shearing efficiency, good consistency in the length of the sheared wire, precise size, smooth shearing surface and no small burrs, which can meet the needs of mass production, has great market value, and is worthy of wide promotion and application.
[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
