Description

Technical Field

[0001] This utility model belongs to the technical field of electrode preparation device, specifically relating to a winding type double-wire tool electrode preparation device. Background Technology

[0002] In electrical discharge machining (EDM) and electrochemical machining, the form of the tool electrode determines the machining efficiency and quality. With increasing manufacturing demands and the development of new materials and technologies, the requirements for tool electrode forms are becoming increasingly stringent, leading to the gradual shift from wire-shaped tool electrodes to dual-wire composite tool electrodes. Compared to the twisted dual-wire tool electrode, which consists of two electrodes twisted together, the wound dual-wire tool electrode is formed by one electrode wire winding around another. This winding structure causes a certain regularity in the electric field distribution between the electrode wires, resulting in variations in the intensity of the discharge or electrolytic reaction at different locations, thus affecting the machining effect. It has certain advantages in machining applications requiring high discharge energy and specific surface morphologies. However, the main drawback of existing devices for the fabrication of dual-wire tool electrodes is:

[0003] Existing devices are mostly twisted-type two-wire tool electrode preparation devices, which rely on the rigidity and large diameter of the wires themselves to maintain the structural stability after twisting. They are used for twisting thicker wires such as cables, but it is difficult to complete the twisting of very small diameter wires used in electrical discharge machining. For the preparation of wound-type two-wire tool electrodes, there is currently a lack of corresponding preparation devices. Although some wire preparation processes include a winding mechanism, existing winding mechanisms generally use a spindle to drive the core wire to rotate, and the wire is attached to the core wire at a fixed angle through a wire guide mechanism. At the same time, the wire guide mechanism moves back and forth along the axial direction to achieve the spiral winding of the wire on the surface of the core wire. Due to the limited travel of the wire guide mechanism, the length of wire processed at one time is limited, and there is idle travel loss. It is impossible to continuously process wound-type two-wire tool electrodes. At the same time, it affects the uniform and neat winding arrangement of the electrode wire. If the wire is unevenly arranged during winding, it will lead to excessive surface roughness of the electrode, unstable conductivity, and even scrap of the workpiece due to uneven partial discharge during electrical discharge machining.

[0004] Secondly, existing winding mechanisms use non-rigid transmissions such as belts and chains, which can lead to slippage and wear, resulting in unstable core wire rotation speed or guide wire movement speed, making it difficult to accurately control the winding pitch of the winding type double-wire tool electrode.

[0005] In addition, the wire is prone to radial runout due to the winding and stretching effect during the winding process. The vibration is more obvious when winding at high speed, which can lead to the deviation of the electrode winding trajectory, the overlap of electrode wires or the excessive gap, affecting the winding accuracy and causing the electrode arrangement to be uneven when taking the wire away. Utility Model Content

[0006] The present invention aims to solve at least one of the above-mentioned technical problems. The present invention provides a winding-type double-wire tool electrode preparation device, which can complete the continuous preparation and neat winding arrangement of winding-type double-wire tool electrodes, and can flexibly adjust the winding pitch and improve the winding accuracy.

[0007] The technical solution adopted by this utility model to solve its technical problem is:

[0008] A device for preparing a wound-type double-wire tool electrode includes a wire feeding mechanism, a wire winding mechanism, and a wire take-up and discharge mechanism arranged sequentially. The wire winding mechanism includes a first driving mechanism and an annular turntable. The first driving mechanism is used to drive the annular turntable to rotate around the axial direction. The annular turntable is provided with a wire winding component. The wire take-up and discharge mechanism includes a second driving mechanism and a wire take-up component. The second driving mechanism is used to drive the wire take-up component to rotate along the radial parallel direction of the annular turntable and to drive the wire take-up component to reciprocate along the radial parallel direction of the annular turntable.

[0009] In order to further reduce the device space, simplify electrode wire feeding, and adapt to the winding position, in a preferred technical solution, the wire feeding mechanism includes a wire feeding component that can rotate along the radial parallel direction of the annular turntable.

[0010] In order to further reduce the device space, simplify the driving of the annular turntable, and improve the winding accuracy, in a preferred technical solution, the first driving mechanism includes a first driving member, a driving gear, and a support assembly. The first driving member is used to drive the driving gear to rotate. The annular turntable is provided with teeth that mesh with the driving gear. The support assembly is used to support the rotation of the annular turntable.

[0011] To further simplify the driving of the annular turntable and facilitate the adjustment of the winding pitch of the dual-wire tool electrode, in a preferred embodiment, the first driving component is a wire winding motor coaxially connected to the drive gear.

[0012] To further improve the support stability of the rotating annular turntable and increase the winding accuracy, in a preferred embodiment, the support assembly includes at least two driven gears that mesh with gear teeth respectively.

[0013] In order to further adapt to the electrode winding trajectory and reduce the influence of bending stress during the electrode winding process, in a preferred technical solution, the winding component can rotate in a direction parallel to the axis of the annular turntable.

[0014] To further simplify the driving of the take-up component, reduce the difficulty of driving control, facilitate the adjustment of the winding pitch, and improve the winding accuracy, in a preferred technical solution, the second driving mechanism includes a second driving member and a third driving member. The second driving member is used to drive the take-up component to rotate in the radial parallel direction of the annular turntable, and the third driving member is used to drive the take-up component and the second driving member to reciprocate in the radial parallel direction of the annular turntable.

[0015] In order to further simplify the rotation drive of the take-up component and improve the uniformity and neatness of the winding arrangement of the dual-wire tool electrode, in a preferred technical solution, the second drive component is a take-up motor coaxially connected to the take-up component.

[0016] To further simplify the wire feeding drive of the take-up component, in a preferred embodiment, the third drive component includes a wire feeding motor, a wire feeding bracket, and a slide rail. The wire feeding motor drives the wire feeding bracket to reciprocate along the slide rail. The wire feeding bracket supports the second drive component and the take-up component. The slide rail is parallel to the radial direction of the annular turntable.

[0017] To further eliminate the shaking of the yarn during the preparation process, which is beneficial for subsequent yarn winding and unwinding and improves the preparation quality, the preferred technical solution includes a shaking-reducing mechanism located between the winding mechanism and the yarn winding and unwinding mechanism. The shaking-reducing mechanism includes at least one set of two pressure rollers spaced apart, and the pressure rollers can rotate in the radial parallel direction along the annular turntable.

[0018] Compared with the prior art, the beneficial effects of this utility model are at least as follows:

[0019] (1) The wire feeding mechanism of this utility model releases the first wire that is wound as the wire in the winding type double wire tool electrode. During the conveying process, the first wire passes through the inside of the annular turntable and is collected by the wire take-up member. The first driving mechanism of the winding mechanism drives the annular turntable to rotate around the axis, so that the wire winding member rotates around the circumference of the first wire. The wire winding member releases the second wire that is wound as the wire in the winding type double wire tool electrode, so that the second wire is continuously wound on the first wire. This can solve the problem of continuous preparation of winding type double wire tool electrodes and improve production efficiency.

[0020] (2) The wire take-up and take-up mechanism of this utility model is driven by the second drive mechanism to rotate the take-up part in the radial parallel direction of the annular turntable, which can collect the prepared double-wire tool electrode on the take-up part. At the same time, the second drive mechanism drives the take-up part to move back and forth in the radial parallel direction of the annular turntable, so that the double-wire tool electrode is evenly and neatly wound and arranged in the take-up part. This can solve the problem of neat winding and arrangement in the continuous preparation of wound double-wire tool electrode, and improve production efficiency and quality.

[0021] (3) The present invention can control the winding speed of the second wire by the first driving mechanism; and / or control the take-up speed of the first wire by the second driving mechanism, so as to flexibly adjust the winding pitch of the double wire tool electrode. It can be used to prepare a double wire tool electrode made of two wires of different diameters and different materials with controllable winding pitch, thereby improving production flexibility and applicability.

[0022] (4) This utility model can further optimize the first driving mechanism and the second driving mechanism to simplify the device and improve the winding accuracy. By adding a vibration elimination mechanism, the vibration of the filaments during the preparation process can be eliminated, which is beneficial to the subsequent filament winding and filament arrangement, and further improves the preparation quality.

Detailed Implementation

[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0027] In the description of this utility model, it should be understood that the terms "upper," "lower," "axial," "radial," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] Given that existing devices are mostly twisted-wire double-wire tool electrode fabrication devices, and that existing winding mechanisms cannot continuously process wound double-wire tool electrodes, thus affecting the uniform and neat winding arrangement of the electrode wire, such as... Figure 1 As shown, this is a preferred embodiment of the winding-type double-wire tool electrode preparation device of the present invention. The winding-type double-wire tool electrode preparation device includes a wire feeding mechanism 20, a wire winding mechanism 21, and a wire take-up and discharge mechanism 22 arranged sequentially. The wire winding mechanism 21 includes a first driving mechanism and an annular turntable 8. The first driving mechanism is used to drive the annular turntable 8 to rotate around the axial direction. The annular turntable 8 is provided with a wire winding member 18. The wire take-up and discharge mechanism 22 includes a second driving mechanism and a wire take-up member 14. The second driving mechanism is used to drive the wire take-up member 14 to rotate in the radial parallel direction of the annular turntable 8 and to drive the wire take-up member 14 to reciprocate in the radial parallel direction of the annular turntable 8.

[0030] For example, taking the example of assembling the wire feeding mechanism 20, the wire winding mechanism 21, and the wire take-up and discharge mechanism 22 on the frame 1, the working principle of the above device can include: the wire feeding mechanism 20 feeds out the first wire 4, which is the wire wound in the wound type double-wire tool electrode. During the conveying process, the first wire 4 passes through the hollow interior of the annular turntable 8 and is collected by the wire take-up member 14. The first drive mechanism of the wire winding mechanism 21 drives the annular turntable 8 to rotate around the axial direction, causing the wire winding member 18 to rotate around the circumference of the first wire 4. As the wire winding member 18 feeds out the second wire 19, which is the wire wound in the wound type double-wire tool electrode, during the forward movement of the first wire 4, the wire feeding mechanism 20 and the wire winding mechanism 21 control the relative positional relationship between the first wire 4 and the second wire 19, so that the second wire 19 is continuously wound around the first wire 4 to form the wound type double-wire tool electrode. At the same time, the second drive mechanism of the wire take-up and discharge mechanism 22 drives the wire take-up member 14 to move parallel to the radial direction of the annular turntable 8. The rotating mechanism collects the prepared double-wire tool electrode 16 onto the take-up member 14. Simultaneously, the second driving mechanism drives the take-up member 14 to reciprocate along the radial parallel direction of the annular turntable 8, ensuring that the double-wire tool electrode 16 is uniformly and neatly wound and arranged in the take-up member 14. This completes the continuous preparation and neat winding arrangement of the wound double-wire tool electrode, solving the technical problems of the inability to continuously process wound double-wire tool electrodes or the difficulty in uniformly and neatly winding and arranging electrode take-up in the prior art. This is beneficial for the efficient and continuous production of wound double-wire tool electrodes, improving the consistency of electrode quality. Furthermore, the winding speed of the second wire 19 can be controlled by the first driving mechanism; and / or, the take-up speed of the first wire 4 can be controlled by the second driving mechanism to flexibly adjust the winding pitch of the double-wire tool electrode 16. This allows for the preparation of double-wire tool electrodes 16 made of two wires of different diameters and materials wound with a controllable winding pitch, providing a foundation for process upgrades in the field of electrical discharge machining.

[0031] Furthermore, the wire feeding mechanism 20 includes a wire feeding member 2, which is rotatable along the radial parallel direction of the annular turntable 8; for example, as Figure 1 As shown, the wire feeding component 2 is a wire feeding disc mounted on the horizontal axis 3 in the frame 1. The horizontal axis 3 is parallel to the radial direction of the annular turntable 8. The first wire 4 can be wound around the wire feeding disc. As the wire take-up and discharge mechanism 22 operates, the wire feeding disc rotates around the horizontal axis 3, that is, the wire feeding component 2 rotates in the radial direction parallel to the annular turntable 8 to feed the wire. This can further reduce the device space, simplify the electrode wire feeding, and adapt to the winding position.

[0032] Furthermore, the first driving mechanism includes a first driving member 5, a drive gear 7, and a support assembly. The first driving member 5 drives the drive gear 7 to rotate. The annular turntable 8 is provided with gear teeth 23 that mesh with the drive gear 7. The support assembly supports the rotation of the annular turntable 8. For example, as... Figure 1As shown, the first driving component 5 and the drive gear 7 are mounted on the column 6 in the frame 1 via a bracket. The gear teeth 23 are located on the outer ring of the annular turntable 8 and mesh with the drive gear 7. The drive gear 7 can be driven to rotate by the first driving component 5, which in turn drives the annular turntable 8 to rotate axially around the annular turntable 8 under the support of the support component. The direct drive by the drive gear 7 and the gear teeth 23 is more efficient than non-rigid transmission drives such as belts and chains, which can further reduce the device space, simplify the drive of the annular turntable 8, avoid slippage and wear problems caused by non-rigid transmissions, and improve winding accuracy. The module matching between the drive gear 7 and the gear teeth 23 is adapted to high-speed winding scenarios.

[0033] Furthermore, the first driving component 5 is a wire-winding motor coaxially connected to the driving gear 7; for example, such as Figure 1 As shown, the winding motor is mounted on the column 6 in the frame 1 by a bracket. The motor shaft of the winding motor is coaxially connected to the drive gear 7, which can further simplify the driving of the annular turntable 8. At the same time, the winding speed of the second wire 19 can be adjusted by adjusting the speed of the winding motor, which facilitates the adjustment of the winding pitch of the double-wire tool electrode 16.

[0034] Furthermore, the support assembly includes at least two driven gears 9 that mesh with the gear teeth 23 respectively; for example, as Figure 1 As shown, the driving gear 7 and the winding motor are mounted on one side column 6 of the frame 1 via a bracket. The two driven gears 9 are arranged vertically and mounted on the other side column 6 of the frame 1 via a bracket, so that the annular turntable 8, the driving gear 7, and the two driven gears 9 form a triangular space and mesh with each other through gear teeth 23. The winding motor drives the driving gear 7 to rotate. During the process of the driving gear 7 driving the annular turntable 8 to rotate through gear teeth 23, the driven gears 9 rotate to support the annular turntable 8. Compared with setting the annular turntable 8 in the annular track, which may generate torque off-center load due to peripheral friction and wear, the multiple driven gears 9 supporting the rotation of the turntable through gear teeth 23 can improve the support stiffness and stability of the turntable rotation, which can further improve the support stability of the annular turntable 8 rotation and improve the winding accuracy.

[0035] Furthermore, the winding member 18 is capable of rotating in a direction parallel to the axial direction of the annular turntable 8; for example, as... Figure 1 As shown, the winding component 18 is a winding spool installed in the inner space of the annular turntable 8 by a bracket. The second wire 19 is wound on the winding spool. As the second wire 19 is continuously wound on the first wire 4, the winding spool rotates parallel to the axial direction of the annular turntable 8 to continuously release wire. Compared with the winding component 18 rotating parallel to the radial direction of the annular turntable 8, the distortion of the winding trajectory caused by the angular deviation during the radial rotation can be avoided, further adapting to the electrode winding trajectory and reducing the influence of bending stress during the electrode winding process.

[0036] Furthermore, the second driving mechanism includes a second driving member 15 and a third driving member 11. The second driving member 15 drives the take-up member 14 to rotate along the radial parallel direction of the annular turntable 8, and the third driving member 11 drives the take-up member 14 and the second driving member 15 to reciprocate along the radial parallel direction of the annular turntable 8; for example, as... Figure 1 As shown, the take-up member 14 is a take-up reel. The second drive member 15 and the third drive member 11 are driven independently to realize the decoupled motion control of the rotation adjustment of the take-up reel and the radial movement control of the take-up reel to arrange the wire. This can further simplify the drive of the take-up member 14, reduce the difficulty of drive control, facilitate the adjustment of the winding distance, and improve the winding accuracy.

[0037] Furthermore, the second drive member 15 is a take-up motor coaxially connected to the take-up member 14, for example, such as Figure 1 As shown, the take-up component 14 is a take-up reel. The take-up reel and the take-up motor are mounted on the take-up bracket 13. The motor shaft of the take-up motor is coaxially connected to the take-up reel, which can further simplify the rotational take-up drive of the take-up component 14. The take-up speed can be adjusted by controlling the rotation speed of the take-up reel through the take-up motor, thereby adjusting the winding pitch of the double-wire tool electrode 16 and improving the uniformity and neatness of the winding arrangement of the double-wire tool electrode 16.

[0038] Furthermore, the third driving component 11 includes a wire-laying motor, a wire-laying bracket 13, and a slide rail 12. The wire-laying motor drives the wire-laying bracket 13 to reciprocate along the slide rail 12. The wire-laying bracket 13 supports the second driving component 15 and the wire-taking component 14. The slide rail 12 is parallel to the radial direction of the annular turntable 8; for example, as... Figure 1 As shown, the wire feeding motor and slide rail 12 are mounted on the frame 1. The motor shaft of the wire feeding motor is connected to a lead screw 24 that is threadedly engaged with the wire feeding bracket 13. The wire feeding bracket 13 is slidably mounted on the slide rail 12. The forward and reverse rotation of the wire feeding motor drives the lead screw 24 to rotate, so that the rotation of the wire feeding bracket 13 is converted into reciprocating linear motion along the slide rail 12 under the guidance and restriction of the threaded engagement and the slide rail 12. By moving the wire feeding bracket 13 and the take-up reel left and right, the wire feeding drive of the take-up component 14 can be further simplified, so that the double-wire tool electrode 16 is evenly and neatly wound and arranged in the take-up reel.

[0039] Furthermore, a de-vibration mechanism 25 is included, located between the winding mechanism 21 and the take-up and unwinding mechanism 22. The de-vibration mechanism 25 includes at least one set of two spaced-apart pressure rollers 17, which are rotatable along the radial parallel direction of the annular turntable 8; for example, as... Figure 1As shown, the pressure roller 17 is made of rubber. The two pressure rollers 17 are arranged vertically and vertically and are mounted on the crossbeam 10 in the frame 1 through the bracket. The double-wire tool electrode 16, which has passed through the winding mechanism, can pass between the two pressure rollers 17. The gap formed by the upper and lower pressure rollers 17 restricts the longitudinal movement of the double-wire tool electrode 16, which can further eliminate the radial vibration of the wire caused by the winding and stretching during the preparation process. It is suitable for high-speed winding scenarios. While eliminating vibration, the pressure rollers 17 can rotate in a direction parallel to the radial direction of the annular turntable 8 and roll and rub against the double-wire tool electrode 16 to avoid scratches on the surface of the double-wire tool electrode 16. The position and number of the two pressure rollers 17 can be configured to suppress vibration at different frequencies, avoiding electrode winding trajectory deviation, electrode wire overlap or excessive gap, which is beneficial for subsequent wire take-up and wire arrangement and improves the preparation quality.
