Description
Technical Field
[0001] This utility model relates to the field of wire cutting, and in particular to a lightweight wire cutting device. Background Technology
[0002] Wire EDM is a key processing technology in modern industrial manufacturing, with wide applications in precision metal machining, composite material cutting, and thermoplastic material molding. This technology primarily relies on the kinetic energy conversion effect generated between a high-speed moving metal cutting wire (such as steel wire) and the workpiece surface, achieving efficient material processing through frictional melting or mechanical cutting principles.
[0003] However, traditional wire EDM equipment is usually equipped with a dedicated motor drive unit and adopts an integrated structural design. This results in a large overall size and bulky structure, making it difficult to adapt to the mobile operation needs of confined working spaces or outdoor scenarios, thus restricting the application scenarios of wire EDM technology. Utility Model Content

[0027] This invention proposes a lightweight wire cutting device.
[0028] like Figures 1 to 3As shown, in one embodiment of this utility model, the lightweight wire cutting device includes a mounting assembly and a cutting coil 4, with the cutting coil 4 mounted on the mounting assembly. Specifically, the mounting assembly includes a pair of symmetrically distributed fixed supports 1, a drive shaft 2, and two first pulleys 3. The drive shaft 2 and the first pulleys 3 are rotatably mounted between the symmetrically distributed fixed supports 1. The fixed supports 1 are V-shaped. The drive shaft 2 is mounted to the bottom of the V-shaped fixed supports 1 via bearings. The two first pulleys 3 are respectively mounted to the top of both sides of the V-shaped fixed supports 1 via fixing bolts (not shown in the figure). The three are arranged in a triangular distribution. The cutting coil 4 is arranged around the drive shaft 2 and the two first pulleys 3. It is worth noting that the portion of the cutting coil 4 located at the V-shaped opening of the fixed supports 1 is the cutting segment, which is typically used by the user for wire cutting operations.
[0029] Furthermore, the aforementioned drive shaft 2 includes an outer section that extends outward through one of the fixed brackets 1 and can be connected to the output end of the drive tool. In this embodiment, the drive tool can be a power tool such as an electric drill or an angle grinder, and the outer section is a hexagonal bolt. In use, the power tool such as the electric drill or angle grinder is connected to the drive shaft 2, thereby driving the drive shaft 2, the first pulley 3, and the cutting coil 4 to rotate to perform the corresponding wire cutting operation.
[0030] Compared to traditional wire EDM equipment, this lightweight wire EDM device does not require a dedicated, integrated motor drive unit, effectively reducing the size and weight of the device. Therefore, it is suitable for confined spaces or outdoor environments, improving the adaptability of wire EDM technology to various scenarios.
[0031] like Figure 1 and 2 As shown, the fixed bracket 1 also includes two first mounting holes 11 and two tensioning bolts 14. Each first mounting hole 11 includes a linear movable area, the linear movable area being in the same direction as the cutting segment. The two ends of the first pulley 3 are respectively located within the first mounting holes 11 of the two fixed brackets 1. The tensioning bolts 14 are located on the side of the first mounting hole 11 facing the adjacent first pulley 3, with one end of the tensioning bolt 14 abutting against the end of the first pulley 3. In this embodiment, after the cutting coil 4 is installed, the user can adjust the relative position of the first pulley 3 and the first mounting holes 11 using the tensioning bolts 14, causing the two first pulleys 3 to move away from each other along the cutting segment's linear direction. This ensures the cutting coil 4 has appropriate tension, meeting the tension requirements of the wire cutting operation, guaranteeing cutting accuracy and safety, and allowing the wire cutting operation to proceed smoothly.
[0032] Specifically, the first mounting hole 11 is an elliptical hole, and the major axis of the elliptical hole is the linear movable area of the end of the first pulley 3. When assembling the fixed bracket 1 and the first pulley 3, the first pulley 3 is first installed between the symmetrically distributed fixed brackets 1 using fixing bolts, leaving a certain amount of movable allowance; after the cutting coil 4 is installed, the two first pulleys 3 are forced to move away from each other along the straight line of the cutting section using tension bolts 14, so that the cutting coil 4 has an appropriate tension force. Then, the first pulley 3 is completely fixed using fixing bolts. At this time, the first pulley 3 is doubly fixed by fixing bolts and tension bolts 14.
[0033] This embodiment also includes positioning bolts (not shown in the figure), and the aforementioned fixing bracket 1 further includes a first arm and a second arm, wherein both the first arm and the second arm include an overlapping area. Specifically, a plurality of limiting holes 13 are provided in the overlapping area of the first arm and the second arm, and the plurality of limiting holes 13 are distributed along the arc of the relative movement of the first arm and the second arm. The positioning bolt can pass through the limiting holes 13 of the first arm and the second arm in sequence and be locked. In addition, the aforementioned cutting coil 4 has a plurality of length dimensions that are the same number as the limiting holes 13.
[0034] like Figure 1 and 3 As shown, the first and second arms of the fixed bracket 1 can rotate relative to each other, thereby changing the angle between the first and second arms. The adjusted state of the first and second arms is then fixed by positioning bolts. Specifically, the number of limiting holes 13 corresponds to the number of adjustable states of the first and second arms. Different angles between the first and second arms correspond to different lengths of cutting coils 4. In use, the user can determine the angle between the first and second arms according to the actual size requirements, then fix the first and second arms with positioning bolts to complete the assembly of the mounting components. Finally, the corresponding size of the cutting coil 4 is installed, thus adapting this lightweight wire cutting device to the current wire cutting operation requirements.
[0035] In this embodiment, the mounting assembly also includes a second pulley, which is rotatably mounted between symmetrically distributed fixed supports 1. The second pulley is sleeved on the drive shaft 2 and rotates synchronously with the drive shaft 2. The second pulley helps the drive shaft 2 to better drive the cutting coil 4. In addition, both the first pulley 3 and the second pulley include limiting grooves. The cutting coil 4 is installed in the limiting grooves. The limiting grooves help improve the stability of the cutting coil 4 rotating around the first pulley 3 and the second pulley.
[0036] Specifically, the working principle and process of this utility model are as follows:
[0037] In this embodiment, the mounting assembly includes only a pair of symmetrically distributed fixed brackets 1, a drive shaft 2, and two first pulleys 3. The drive shaft 2 is connected to the output end of a driving tool such as an electric drill to drive the cutting coil 4 to rotate. This allows users to perform corresponding wire cutting operations using this lightweight wire cutting device without the need for a dedicated, integrated motor drive unit. This effectively reduces the size and weight of the wire cutting device, making it suitable for confined working spaces or outdoor scenarios, thus improving the adaptability of wire cutting technology to various scenarios.
[0038] In addition, users can determine the included angle between the first and second arms according to the actual size requirements of the application, and then fix the first and second arms with positioning bolts to complete the assembly of the installation components. Then, the corresponding size of the cutting coil 4 is installed, so that the lightweight wire cutting device can adapt to the current wire cutting operation requirements, further increasing the application scenarios that the lightweight wire cutting device can adapt to, and improving the application scenarios of wire cutting technology.
[0039] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
