Description

Technical Field

[0001] This utility model belongs to the field of cutting wire manufacturing equipment, and specifically relates to a cutting wire deformation device. Background Technology

[0002] Slurry wire EDM uses a cutting wire to carry loose slurry into the cutting edge of a hard material, thus cutting the material with the slurry. Therefore, the slurry-carrying capacity of the cutting wire directly affects the cutting efficiency.

[0003] Bending and deforming the cutting wire to form ripples or other shapes is an effective way to improve the abrasive carrying capacity of the cutting wire. Since the direction of the cutting wire changes randomly during the cutting process and is difficult to control, in order to ensure the abrasive carrying capacity of the cutting wire in all directions, it is often necessary to twist the cutting wire to form a spiral structure, so that the cutting wire has a deformable structure in all directions.

[0004] The cutting wire is usually twisted by using a rotating mechanism to rotate it and create a spiral structure. This method requires a separate rotating mechanism, making the structure relatively complex. Utility Model Content

[0005] To address the shortcomings of complex structures in existing cutting wire deformation mechanisms, this utility model provides a cutting wire deformation device.

[0006] The technical solution adopted by this utility model is as follows: a cutting wire deformation device, comprising a first deformation mechanism, a screw mechanism, a second deformation mechanism and a traction mechanism arranged in sequence. The first deformation mechanism includes a pair of meshing first gears, and the second deformation mechanism includes a pair of meshing second gears. The line connecting the midpoint of the distance between the axes of the pair of first gears and the midpoint of the distance between the axes of the pair of second gears is collinear with the axis of the screw mechanism.

[0007] In one embodiment, the axis of the first gear is parallel to the axis of the second gear.

[0008] In another embodiment, the axis of the first gear is perpendicular to the axis of the second gear.

[0009] Furthermore, specifically, in some embodiments, the screw mechanism sequentially includes an inlet section, a threaded section, and an outlet section along the cutting wire's travel direction. The inlet section has an inlet hole at its center on its end face, and an inlet channel is formed between the inlet hole and the threaded start end of the threaded section. The outlet section has an outlet hole at its center on its end face, and an outlet channel is formed between the outlet hole and the threaded end of the threaded section.

[0010] In some embodiments, the inlet channel smoothly connects the inlet hole and the thread start end; the outlet channel smoothly connects the outlet hole and the thread end.

[0011] Specifically, in some embodiments, a mounting frame is also included, on which the first gear, screw mechanism, and second gear are all mounted.

[0012] In some embodiments, the screw mechanism is provided with connecting rods on the input and output sections, and the screw mechanism is mounted on the mounting frame via the connecting rods.

[0013] In some embodiments, the depth of the thread on the screw mechanism is at least twice the diameter of the cutting wire substrate.

[0014] Beneficial effects: This utility model sets a screw mechanism on the path of the cutting wire, so that the cutting wire will naturally twist and deform as it travels along the thread of the screw mechanism, thereby forming a spiral structure. There is no need to set up an independent rotating mechanism, the structure is simpler, and the equipment cost is reduced. Attached Figure Description

[0020] The present invention will be further described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative changes are within the protection scope of the present invention.

[0021] like Figure 1 and 2As shown, the structure of the cutting wire deformation device provided by this utility model is as follows: it includes a first deformation mechanism, a screw mechanism 2, a second deformation mechanism, and a traction mechanism 4 arranged in sequence. The first deformation mechanism includes a pair of meshing first gears 1, and the second deformation mechanism includes a pair of meshing second gears 3. The line connecting the midpoint of the distance between the axes of the pair of first gears 1 and the midpoint of the distance between the axes of the pair of second gears 3 is collinear with the axis of the screw mechanism 2.

[0022] Under the traction power of the traction mechanism 4, the cutting wire first passes through the first deformation mechanism. A pair of meshing first gears 1 in the first deformation mechanism deform the cutting wire for the first time, forming a corrugated structure. Then, it winds around the threaded structure along the screw mechanism 2 and undergoes a second deformation through the second deformation mechanism. During this process, the threaded structure of the screw mechanism 2 causes the cutting wire to form a spring-like structure. Due to the traction action of the traction mechanism 4 at the rear end of the second deformation mechanism, the spring-like structure of the cutting wire tends to straighten when entering the second deformation mechanism. Simultaneously, the gears of the first and second deformation mechanisms clamp the cutting wire, preventing the torsional force exerted by the screw mechanism 2 on the cutting wire from being released. This stretches the spring-like structure of the cutting wire, forming a spiral structure that twists along its own axis. Ultimately, a cutting wire with corrugated, spiral, and second corrugated structures is formed. The spiral structure makes the corrugated structure more uniform in all directions of the cutting wire, which is beneficial for improving the wire's sand-carrying capacity and cutting efficiency during the cutting process. This utility model device does not require an additional rotary power mechanism to drive the cutting wire to rotate, nor does it require a torsion limit wheel or other mechanism that works with the rotary power mechanism, which greatly simplifies the equipment structure.

[0023] like Figure 1 As shown in one embodiment, the axis of the first gear 1 is parallel to the axis of the second gear 3. Although the axis of the first gear 1 is parallel to the axis of the second gear 3, meaning that the ripples formed by the deformation of the cutting wire are in the same direction, the screw mechanism 2 is provided at the rear end of the first deformation mechanism. The spiral structure formed by the screw mechanism 2 causes the ripple structure formed by the first deformation mechanism to be distributed in various directions. The second deformation mechanism performs superimposed deformation on the basis of the first thread deformation and spiral structure, further increasing the deformation structure of the cutting wire and improving the sand-carrying capacity of the cutting wire.

[0024] like Figure 2 As shown, in another embodiment, unlike the above embodiment, the axis of the first gear 1 is perpendicular to the axis of the second gear 3. The first gear 1 and the second gear 3 produce corrugations in different directions due to the deformation of the cutting wire, further improving the distribution of the deformed structure on the cutting wire in all directions and enhancing the cutting wire's sand-carrying capacity.

[0025] like Figure 3 As shown, specifically, the screw mechanism 2 includes, in sequence along the cutting wire travel direction, an inlet section 21, a threaded section 22, and an outlet section 23. The inlet section 21 has an inlet hole 211 at its end face center, and an inlet channel 212 is provided between the inlet hole 211 and the thread start end of the threaded section 22. The outlet section 23 has an outlet hole 231 at its end face center, and an outlet channel 232 is provided between the outlet hole 231 and the thread end of the threaded section 22. After being deformed by the first deformation mechanism, the cutting wire enters the threaded section 22 of the screw mechanism 2 through the inlet hole 211 and the inlet channel 212. After passing through the threaded path of the threaded section 22, it is discharged through the outlet channel 232 and the outlet hole 231. The inlet hole 211, the inlet channel 212, the outlet hole 231, and the outlet channel 232 can effectively guide the cutting wire into and out of the screw mechanism 2, and also prevent the cutting wire from detaching from the threaded path of the threaded section 22 during its journey, thus playing a limiting role. Moreover, the outlet channel 232 also helps the spring-like structure of the cutting wire to tend to straighten and transform into a spiral structure that twists along its own axis. At the same time, setting the inlet hole 211 and the outlet hole 231 on the axis of the screw mechanism 2 can also prevent the cutting wire from deviating on the first deformation mechanism and the second deformation mechanism, making the equipment operation more stable.

[0026] To improve the service life of the screw mechanism 2 and reduce wear from the cutting wire, a lubricating coating, such as a polytetrafluoroethylene coating, is applied to the wire inlet channel 212 and wire outlet channel 232 of the threaded section 22 of the screw mechanism 2. This is an effective method. To prevent the cutting wire from dislodging from the threads of the screw mechanism 2 during travel, the depth of the threads on the screw mechanism 2 is at least twice the diameter of the cutting wire substrate. The cutting wire travels entirely within the threaded structure of the threaded section 22, improving the stability of equipment operation.

[0027] To facilitate smoother entry of the cutting wire from the inlet hole 211 into the thread start end of the threaded section 22 and from the end of the threaded section 22 into the outlet hole 231, the inlet channel 212 smoothly connects the inlet hole 211 and the thread start end; the outlet channel 232 smoothly connects the outlet hole 231 and the thread end, specifically through an arc-shaped channel structure.

[0028] To facilitate the installation and assembly of the mechanism, specifically, the wire cutting deformation device also includes a mounting frame 5, on which the first gear 1, screw mechanism 2, and second gear 3 are all mounted. The mounting frame 5 allows the first deformation mechanism, screw mechanism 2, and second deformation mechanism to be assembled into a single module, which can then be installed on different production lines. For example, it can be installed at the rear end of a wire drawing equipment to guide the drawn steel wire into the deformation device of this application for direct deformation to form a cutting wire. Alternatively, it can be installed at the rear end of a wire feeding equipment to deform the steel wire unwound by the feeding equipment, allowing for flexible assembly.

[0029] like Figure 4 As shown, to facilitate the installation of the screw mechanism 2 within the mounting frame 5, specifically, connecting rods 24 are provided on the input section 21 and output section 23 of the screw mechanism 2, and the screw mechanism 2 is mounted on the mounting frame 5 via the connecting rods 24. The shafts of the first gear 1 and the second gear 3 can be directly mounted on the mounting frame 5.

[0030] The above content is only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed in this utility model shall fall within the scope of protection of the claims of this utility model.
