Description

Technical Field

[0001] The present invention relates to the technical field of wire cutting and forming, and in particular to a novel double-tool cutting module. Background Art

[0002] Currently, metal wire products on the market are mainly produced by CNC 3D wire forming machines, which complete the main bending, cutting and other production processes. For common CNC 3D wire forming machines, please refer to the invention patent previously applied for by the applicant, patent number 201710607638.5, which discloses a fully automatic CNC 3D wire forming machine.

[0003] The above-mentioned metal wire products mainly include daily hardware wire products, iron wire craft products, various mesh cages and various hook structures. Figure 1 In the mesh cage 10 shown, the prior art generally uses a CNC 3D wire forming machine to sequentially straighten, bend, and cut the wire to produce the various subassemblies 11 that make up the mesh cage 10. Subsequently, when all the subassemblies 11 are prepared, they are combined and welded to form the complete mesh cage 10.

[0004] With the diversification of product designs, such as Figure 2 As shown, many metal wire products currently have aesthetically optimized processing (rounded corners or other shapes) at both ends of the sub-accessories, and the current CNC 3D wire forming machine is unable to complete the aesthetic forming process of the sub-accessory 11 at both ends, resulting in the sub-accessory 11 still requiring external equipment to perform forming processing on both ends after being processed by the CNC 3D wire forming machine. Moreover, since the sub-accessory 11 has completed the bending processing, the other end (end) of the sub-accessory 11 will cause interference when the head end is being formed, which not only increases the difficulty of process production, but also further reduces production efficiency. Secondly, due to the secondary clamping and positioning of the forming process, the forming accuracy of the metal wire product is low, and the beautification effect is insufficient. Therefore, the present invention proposes a new double-tool cutting module. Summary of the Invention

[0005] The present invention provides a novel double-tool cutting module, which solves the technical problem in the prior art that a CNC 3D wire forming machine cannot complete the wire cutting and forming process in one go.

[0006] The object of the present invention is achieved in the following ways:

[0007] A new type of double-position cutting module is used in a wire forming machine. The double-position cutting module includes a fixed frame, a cutting knife and a driving structure for driving the cutting knife to move back and forth. Two forming knife seats are relatively arranged on the fixed frame, and a forming cavity for accommodating the cutting knife is provided between the two forming knife seats. A mold core for forming the forming cavity is respectively provided on the adjacent side of the two forming knife seats, and a material channel is provided on the fixed frame that sequentially passes through the two forming knife seats.

[0008] Furthermore, the mold core adopts a protrusion or groove structure, and the mold core extends along the moving direction of the cutting knife to form a guide portion that slides with the cutting knife.

[0009] Furthermore, the cutting knife is arranged in a V shape, and the middle part of the cutting knife cooperates 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 driving structure includes a driving motor, an eccentric wheel mounted on the driving motor, and a transmission bracket rotatably mounted at one end of the fixed frame. The cutting knife is fixedly mounted on the transmission bracket, and the transmission bracket is provided with a driving slot for cooperating with the eccentric wheel.

[0012] Furthermore, the eccentric wheel includes an eccentric shaft body for connecting to the output end of the drive motor, a bearing sleeved on the eccentric shaft body, and a fixed cover plate installed at the end of the eccentric shaft body.

[0013] Furthermore, the eccentric shaft body is composed of a first shaft portion and a second shaft portion eccentrically arranged on one side of the first shaft portion. The first shaft portion is connected to the output end of the driving motor and is concentrically arranged therewith.

[0014] Furthermore, the fixed cover is mounted on a side of the second shaft portion away from the first shaft portion, and the output end of the drive motor passes through the eccentric shaft body to be fixedly connected to the fixed cover.

[0015] Furthermore, the driving structure includes a linear cylinder or a linear electric cylinder.

[0016] The present invention utilizes a dual-forming tool design, allowing the cutting module to simultaneously complete the wire cutting process while also achieving aesthetic shaping of both ends of the wire, avoiding the cumbersome secondary shaping process required by traditional technologies, which requires additional equipment. Thanks to the integration of the dual-forming tool cutting module, the existing cutting and aesthetic shaping processes can be combined into one, significantly improving production efficiency while also avoiding the issues of secondary clamping and positioning of the wire. This significantly improves the forming accuracy of metal wire products, ensures aesthetic shaping effects, shortens production cycles, and effectively reduces production costs.

DETAILED DESCRIPTION

[0027] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0028] Example 1:

[0029] In this embodiment, refer to Figure 1 - Figure 8 , which specifically implements a new double-tool cutting module for a wire forming machine, including a fixed frame 1, a cutting knife 2 and a driving structure for driving the cutting knife 2 to move back and forth, two forming knife seats 3 are relatively arranged on the fixed frame 1, a forming cavity for accommodating the cutting knife 2 is provided between the two forming knife seats 3, and a mold core 301 for forming the forming cavity is respectively provided on the adjacent side of the two forming knife seats 3, and a material channel 302 is provided on the fixed frame 1 that sequentially passes through the two forming knife seats 3.

[0030] In this embodiment, the mold core 301 adopts a semicircular convex structure, the purpose of which is to form a semicircular convex structure at both ends of the wire. Figure 2 The rounded structure shown.

[0031] Furthermore, in order to meet the requirements of diversified product design, the shape of the mold core 301 can be adjusted according to the actual needs of the wire. Different shapes of the mold core 301 can produce wires of different shapes, such as Figure 9 As shown, a core mold 301 with a groove structure and a core mold 301 with a protrusion structure are arranged on both sides of the cutting blade 2, respectively. This allows the protrusion and groove structures to be cut and formed at the beginning and end of the wire rod, respectively. Furthermore, serrated, oblique, triangular, or other irregularly shaped protrusions and grooves can also be produced. Using core molds 301 of different shapes ensures that the wire rod can achieve different molding and aesthetic effects, achieving diversified product design.

[0032] In this embodiment, the drive structure includes a drive motor 5, an eccentric wheel 6 mounted on the drive motor 5, and a transmission bracket 7 rotatably mounted at one end of the fixed frame 1. The cutting blade 2 is fixedly mounted on the transmission bracket 7, and the transmission bracket 7 is provided with a drive notch 701 for cooperating with the eccentric wheel 6. In actual use, the drive motor 5 drives the eccentric wheel 6 to rotate eccentrically within the drive notch 701, thereby driving the transmission bracket 7 to swing back and forth along one end of the fixed frame 1, thereby driving the cutting blade 2 to reciprocate, so that the cutting blade 2 can cooperate with the two mold cores 301 to complete the cutting and forming 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 fixed 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 arranged to one side of the first shaft portion. The first shaft portion is connected to the output end of the drive motor 5 and is arranged concentrically therewith. The fixed cover plate 603 is installed on the side of the second shaft portion away from the first shaft portion. The output end of the drive motor 5 passes through the eccentric shaft 601 and is fixedly connected to the fixed 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 knife 2 to form a guide portion that slides with the cutting knife 2. The function of the guide portion is to improve the smoothness of the reciprocating movement of the cutting knife 2 and avoid jamming.

[0036] Furthermore, the cutting knife 2 is arranged in a V shape, and the middle part of the cutting knife 2 cooperates with the mold core 301. The V-shaped arrangement of the cutting knife 2 can effectively concentrate the wire during the cutting and forming process, avoid the deviation of the wire, and improve the forming accuracy and efficiency of the wire.

[0037] Furthermore, the forming tool holder 3 is rotatably mounted on the fixed frame 1 for adapting to different wires or different wire input angles or different cutting angles. The fixed frame 1 is provided with screws for fixing the forming tool 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 also adopts the same rectangular setting as the wire structure to ensure the stability of the wire movement.

[0039] The present invention utilizes a dual-forming tool design, allowing the cutting module to simultaneously complete the wire cutting process while also aesthetically shaping the wire ends, avoiding the cumbersome secondary forming process required by traditional techniques, which requires additional equipment. Thanks to the integration of the dual-forming tool cutting module, existing wire forming machines can combine the cutting and aesthetic forming processes into one, significantly improving production efficiency while also avoiding the need for secondary clamping and positioning of the wire. This significantly improves the forming accuracy of metal wire products, ensures aesthetically pleasing molding results, shortens production cycles, and effectively reduces production costs.

[0040] In actual application, the input and output ends of the double-blade cutting module are respectively connected to the straightening mechanism and bending mechanism of the wire forming machine. The straightened wire enters the two forming knife seats 3 through the material channel 302. At that time, driven by the driving structure, the reciprocating cutting knife 2 and the outer contour of the mold core 301 form a shear force, thereby cutting and forming the wire located at the forming cavity position. The mold core 301 arranged on both sides of the cutting knife 2 enables it to complete the cutting and forming process of the wire ends at one time, greatly improving production efficiency.

[0041] Example 2:

[0042] The difference between this embodiment and the first embodiment is that the driving structure adopts a linear cylinder or a linear electric cylinder that can drive the cutting knife 2 to perform linear reciprocating motion.

[0043] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention is disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments according to the technology of the present invention are all within the scope of the technical solution of the present invention without departing from the content of the technical solution of the present invention.
