Technical Field
[0001] This utility model relates to the field of wire cutting and forming technology, specifically to a novel dual-blade cutting module. Background Technology
[0002] Currently, the main production processes of metal wire products on the market, such as bending and cutting, are completed by CNC 3D wire forming machines. For a specific example of a common CNC 3D wire forming machine, please refer to the invention patent previously filed by the applicant, patent number 201710607638.5, which discloses a fully automatic CNC 3D wire forming machine.
[0003] The aforementioned metal wire products mainly include daily-use hardware wire products, iron wire craft products, various mesh cages, and various hook structures. In production... Figure 1 In the present invention, the existing technology typically employs a CNC 3D wire forming machine to sequentially straighten, bend, and cut the wire to manufacture the various sub-components 11 that constitute the mesh cage 10. Subsequently, with all sub-components 11 prepared, they are assembled and welded into a complete mesh cage 10.
[0004] With the diversification of product design, such as Figure 2 As shown, many metal wire products currently undergo aesthetic enhancement treatments (rounded corners or other shapes) at both ends of sub-components. However, current CNC 3D wire forming machines cannot complete the aesthetic forming process at both ends of sub-component 11. This results in sub-component 11 requiring external equipment to form its ends after processing by the CNC 3D wire forming machine. Furthermore, since sub-component 11 has already undergone bending, interference occurs at the other end (the end point) during the forming process, increasing the difficulty of production and further reducing efficiency. Additionally, the secondary clamping and positioning during forming results in lower forming accuracy and insufficient aesthetic effect in the metal wire products. Therefore, this utility model proposes a novel dual-blade cutting module. Summary of the Invention
[0005] This utility model provides a novel dual-blade cutting module, which solves the technical problem that existing CNC 3D wire forming machines cannot complete the wire cutting and forming process in one go.
[0006] The objective of this utility model is achieved through the following means:
[0007] A novel dual-blade cutting module is applied to a wire forming machine. The dual-blade cutting module includes a fixed frame, a cutting blade, and a drive structure for driving the cutting blade to reciprocate. Two forming blade holders are arranged opposite each other on the fixed frame, and a forming cavity for accommodating the cutting blade is provided between the two forming blade holders. A mold core for forming the forming cavity is provided on the adjacent side of the two forming blade holders. A material channel is provided on the fixed frame that passes through the two forming blade holders in sequence.
[0008] Furthermore, the mold core adopts a protrusion or groove structure, and the mold core extends along the moving direction of the cutting blade to form a guide portion that slides with the cutting blade.
[0009] Furthermore, the cutting blade is V-shaped, and the middle part of the cutting blade mates with the mold core.
[0010] Furthermore, the forming tool holder is rotatably mounted on a fixed frame, and the fixed frame is provided with screws for fixing the forming tool holder.
[0011] Furthermore, the drive structure includes a drive motor, an eccentric wheel mounted on the drive motor, and a transmission bracket rotatably mounted on one end of the fixed frame. The cutting blade is fixedly mounted on the transmission bracket, and the transmission bracket is provided with a drive slot for cooperating with the eccentric wheel.
[0012] Furthermore, the eccentric wheel includes an eccentric shaft for connecting to the output end of the drive motor, a bearing sleeved on the eccentric shaft, and a fixed cover plate installed at the end of the eccentric shaft.
[0013] Furthermore, the eccentric shaft is composed of a first shaft portion and a second shaft portion eccentrically disposed on one side of the first shaft portion. The first shaft portion is connected to the output end of the drive motor and is concentrically disposed therewith.
[0014] Furthermore, the fixing cover is installed on the side of the second shaft away from the first shaft, and the output end of the drive motor passes through the eccentric shaft and is fixedly connected to the fixing cover.
[0015] Furthermore, the drive structure includes a linear cylinder or a linear electric cylinder.
[0016] This invention employs a dual-forming blade design, enabling the cutting module to simultaneously perform aesthetic shaping of both ends of the wire while cutting, avoiding the cumbersome secondary shaping steps required by traditional technologies. Thanks to the integration of the dual-forming blade cutting module, the existing cutting and aesthetic shaping processes can be combined into one, significantly improving production efficiency while avoiding secondary clamping and positioning issues for the wire. This results in significantly improved forming accuracy of metal wire products, ensuring aesthetically pleasing shaping effects, shortening the production cycle, and effectively reducing production costs.

Detailed Implementation
[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0028] Example 1:
[0029] In this embodiment, refer to Figure 1 - Figure 8 The present invention relates to a novel dual-blade cutting module for use in a wire forming machine, comprising a fixed frame 1, a cutting blade 2, and a drive structure for driving the cutting blade 2 to reciprocate. Two forming blade holders 3 are arranged opposite to each other on the fixed frame 1, and a forming cavity for accommodating the cutting blade 2 is provided between the two forming blade holders 3. A mold core 301 for forming the forming cavity is provided on the adjacent side of the two forming blade holders 3, and a material channel 302 is provided on the fixed frame 1 that passes through the two forming blade holders 3 in sequence.
[0030] In this embodiment, the mold core 301 adopts a semi-circular protrusion structure, the purpose of which is to enable the two ends of the wire to form a shape like... Figure 2 The rounded corner structure shown.
[0031] Furthermore, to meet the diverse requirements of product design, the die core 301 can be adjusted in shape according to the actual needs of the wire. Different shapes of die cores 301 can produce wires of different shapes, such as... Figure 9 As shown, grooved mold cores 301 and raised mold cores 301 are respectively arranged on both sides of the cutting blade 2, which can cut raised and grooved structures at both ends of the wire. Furthermore, serrated structures, beveled structures, triangular structures, or other irregular raised and grooved structures can also be produced. Using mold cores 301 of different shapes can ensure that the wire forms different molding and aesthetic effects, realizing the diversification of product design.
[0032] In this embodiment, the driving structure includes a drive motor 5, an eccentric wheel 6 mounted on the drive motor 5, and a transmission bracket 7 rotatably mounted on one end of the fixed frame 1. The cutting blade 2 is fixedly mounted on the transmission bracket 7, which has a drive slot 701 for engaging with the eccentric wheel 6. In actual use, the drive motor 5 drives the eccentric wheel 6 to rotate eccentrically within the drive slot 701, thereby driving the transmission bracket 7 to reciprocate along one end of the fixed frame 1. This drives the cutting blade 2 to reciprocate, enabling it to engage with the two mold cores 301 to complete the cutting and shaping action.
[0033] Furthermore, the eccentric wheel 6 includes an eccentric shaft 601 for connecting to the output end of the drive motor 5, a bearing 602 sleeved on the eccentric shaft 601, and a fixing cover plate 603 installed at the end of the eccentric shaft 601. The eccentric shaft 601 is composed of a first shaft portion and a second shaft portion eccentrically disposed on one side of the first shaft portion. The first shaft portion is connected to and concentrically disposed with the output end of the drive motor 5. The fixing cover plate 603 is installed on the side of the second shaft portion away from the first shaft portion, and the output end of the drive motor 5 passes through the eccentric shaft 601 and is fixedly connected to the fixing cover plate 603.
[0034] Furthermore, the transmission bracket 7 is rotatably mounted on one end of the fixed frame 1 via the rotating shaft structure 4.
[0035] In this embodiment, the mold core 301 extends along the moving direction of the cutting blade 2 to form a guide portion that slides with the cutting blade 2. The function of the guide portion is to improve the smoothness of the reciprocating movement of the cutting blade 2 and avoid jamming.
[0036] Furthermore, the cutting blade 2 is V-shaped, and the middle part of the cutting blade 2 cooperates with the mold core 301. The V-shaped design of the cutting blade 2 can effectively concentrate the wire during the cutting and forming process, avoid wire deviation, and improve the forming accuracy and efficiency of the wire.
[0037] Furthermore, the forming blade holder 3 is rotatably mounted on the fixed frame 1 to adapt to different wires or different wire input angles or different cutting angles. The fixed frame 1 is provided with screws for fixing the forming blade holder 3.
[0038] Specifically, the mesh cage produced in this embodiment adopts a wire structure with a rectangular cross-section. Therefore, the cross-sectional shape of the material channel 302 is also set in the same rectangular shape as the wire structure to ensure the stability of the wire movement.
[0039] This invention employs a dual-forming blade design, enabling the cutting module to simultaneously perform aesthetic shaping of both ends of the wire while cutting, thus avoiding the cumbersome secondary shaping steps required by traditional technologies. Thanks to the integration of the dual-forming blade cutting module, existing wire forming machines can combine cutting and aesthetic shaping processes into one, significantly improving production efficiency while avoiding secondary clamping and positioning issues. This results in significantly improved forming accuracy of metal wire products, ensuring aesthetically pleasing results, shortening production cycles, and effectively reducing production costs.
[0040] In practical applications, the input and output ends of the dual-blade cutting module are connected to the straightening mechanism and bending mechanism of the wire forming machine, respectively. The straightened wire enters the two forming blade holders 3 through the material channel 302. At that time, driven by the drive structure, the reciprocating cutting blade 2 forms a shearing force with the outer contour of the mold core 301, thereby cutting and forming the wire located at the forming cavity. The mold core 301 set on both sides of the cutting blade 2 enables it to complete the cutting and forming process of the beginning and end of the wire in one go, which greatly improves the production efficiency.
[0041] Example 2:
[0042] The difference between this embodiment and Embodiment 1 is that the driving structure uses a linear cylinder or linear electric cylinder that can drive the cutting blade 2 to perform linear reciprocating motion.
[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
