Description

Technical Field

[0001] This utility model belongs to the technical field of molybdenum wire feeding equipment, specifically relating to a swing-assisted molybdenum wire feeding mechanism. Background Technology

[0002] In the field of wire EDM, molybdenum wire is an important electrode consumable, and molybdenum wire installation is a crucial step in processing preparation. Traditional wire EDM machines tend to coil the molybdenum wire during the loading process, causing it to become haphazardly and disorderly wound on the wire spool. This can also lead to the wire slipping out of the guide roller's limiting groove. Once the wire jumps out of the guide roller, the machine must be stopped and readjusted, increasing the difficulty and time required for wire loading. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned problems by providing a swing-assisted molybdenum wire mechanism.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a rocking-assisted molybdenum wire upper mechanism, including a bed, a rocking column provided on one side of the bed, an upper cantilever connected to the rocking column and located horizontally above the bed, an upper molybdenum wire structure parallel to the upper cantilever on the upper side of the upper cantilever, a wire-pulling clamp assembly movably provided within the upper molybdenum wire structure, and the wire-pulling clamp assembly axially moving along the length direction of the upper molybdenum wire structure via a wire-pulling drive mechanism.

[0005] In the aforementioned swing-assisted molybdenum wire upper structure, the upper molybdenum wire structure includes a wire drawing support connected to the upper cantilever. The upper end of the wire drawing support has a wire drawing cover plate along its width direction. The inner side of the wire drawing support has a mounting cavity, and an axially extending opening connecting the wire drawing support and the wire drawing cover plate communicates with the mounting cavity. The wire drawing support is designed with a built-in mounting cavity that encloses core transmission components such as the ball bearing guide and synchronous belt, forming a closed or semi-closed space. This effectively prevents the intrusion of electrolytic corrosion products and dust, improving the reliability and lifespan of the transmission system.

[0006] In the aforementioned swing-assisted molybdenum wire mechanism, the drawing cover plate has a vertically arranged cover plate connecting part on the side near the drawing support. The lower end of the cover plate connecting part is connected to the opening side, and the upper end of the cover plate connecting part, away from the drawing support, has a bending part. An active space is formed between the bending part and the cover plate connecting part, and this active space communicates with the mounting cavity through the opening. The design of the cover plate connecting part and the bending part significantly enhances the structural strength and bending stiffness of the drawing cover plate itself, making it less prone to deformation when subjected to the torque generated by the movement of the clamp assembly, thus ensuring the stability of the movement. Simultaneously, the active space formed by the bending part and the cover plate connecting part provides the necessary precise guidance and limiting space for the axial movement of the drawing clamp assembly, while also ensuring communication with the internal mechanism.

[0007] In the aforementioned swing-assisted molybdenum wire mechanism, the length of the bending portion is less than the length of the cover plate connecting portion. The cover plate connecting portion, near the movable space, has miniature inductive switches at both ends that match the wire-drawing clamp assembly, and these miniature inductive switches are located above the opening. The placement of these miniature inductive switches at both ends of the cover plate connecting portion and above the opening reduces the risk of false triggering and damage, while also accurately detecting whether the clamp assembly has moved into position, thus achieving precise control.

[0008] In the aforementioned swing-assisted molybdenum wire feeding mechanism, the wire-drawing clamp assembly has a lower clamp block located within the movable space. The lower clamp block has an installation notch on the side away from the cover plate connection portion, and an upper clamp block is located within the installation notch. The lower clamp block has an inclined portion on its lower side, and a wire-drawing inlet groove is formed between the inclined portion and the lower clamp block. The lower clamp block, moving within the movable space, itself acts as a guide, ensuring the assembly moves along a predetermined trajectory without requiring an additional guiding mechanism. The wire-drawing inlet groove formed by the inclined portion of the upper clamp block and the lower clamp block is a V-shaped or wedge-shaped structure. This design automatically guides the molybdenum wire to slide into the bottom of the groove, achieving fast and accurate wire feeding operations, simplifying manual operation, and improving efficiency.

[0009] In the aforementioned swing-assisted molybdenum wire drawing mechanism, the drawing drive mechanism includes a ball bearing guide axially arranged within the mounting cavity. The upper side of the ball bearing guide extends into the movable space through an opening and contacts the cover plate connection portion. A transmission slider is movably connected to the ball bearing guide. The lower clamp block has a slider connection notch near the cover plate connection portion that connects to the upper end of the transmission slider, and the lower end of the transmission slider is connected to the drive connection assembly. Using a ball bearing guide as the guiding element has the advantages of low friction coefficient, smooth movement, high precision, and good rigidity, ensuring precise and wobbly reciprocating motion of the drawing clamp assembly. The transmission slider is directly connected to the lower clamp block, and the drive connection assembly directly transmits the power of the synchronous belt to the transmission slider. This direct drive method reduces intermediate links, has a short transmission chain, good rigidity, fast response speed, and no backlash, ensuring positioning accuracy.

[0010] In the aforementioned swing-assisted molybdenum wire mounting mechanism, a motor mounting base is provided on the inner side of the middle of the wire drawing support, and a drive motor connected to the motor mounting base is provided on the outer side of the middle of the wire drawing support. The motor shaft of the drive motor axially passes through the wire drawing support into the mounting cavity. A main synchronous pulley connected to the motor shaft is provided on the side of the motor mounting base away from the drive motor. Auxiliary pulleys are provided side-by-side at both ends of the main synchronous pulley. Synchronous pulley mounting bases are provided at both ends of the mounting cavity, and a secondary synchronous pulley is provided at the lower end of the synchronous pulley mounting base. A synchronous belt is wound around the main synchronous pulley, auxiliary pulley, and secondary synchronous pulley. The drive motor is embedded in the mounting groove, and the motor shaft extends directly into the mounting cavity to drive the main synchronous pulley. This built-in design greatly saves axial space, making the entire molybdenum wire mounting mechanism very compact. At the same time, the use of synchronous belts and main and secondary synchronous pulleys for transmission ensures precise synchronization of the transmission, with no slippage. The motor speed and the clamp movement distance strictly correspond, and the auxiliary pulleys are used for tensioning and increasing the wrap angle to prevent the synchronous belt from slipping or jumping, ensuring smooth and reliable transmission.

[0011] In the aforementioned oscillating assist molybdenum wire mechanism, the drive connection assembly includes a connecting sheet metal disposed at the lower end of the transmission slider on the side away from the ball guide rail. The connecting sheet metal has a vertical connecting portion fixedly connected to the transmission slider. A horizontal connecting portion is provided at the lower end of the vertical connecting portion. An oblique connecting portion is provided between the horizontal and vertical connecting portions, and a fixing plate connected to the timing belt is provided at the end of the horizontal connecting portion away from the oblique connecting portion. The design of the vertical, oblique, and horizontal connecting portions of the connecting sheet metal is a very ingenious avoidance structure. It allows the fixing plate of the timing belt to avoid the space below the ball guide rail and the transmission slider, connecting from the side. This solves the problem of power transmission between components with different axes in a compact space. Simultaneously, the use of sheet metal structure ensures connection rigidity while achieving lightweighting, reducing the inertia of moving parts, and facilitating rapid motor start-stop and precise control.

[0012] In the above-mentioned swing-assisted molybdenum wire mechanism, the outer side of the middle part of the wire drawing support has a mounting groove, the drive motor is located in the mounting groove, and the end of the mounting groove away from the drive motor is provided with a cantilever fixing seat connected to the upper cantilever.

[0013] In the above-mentioned swing-assisted molybdenum wire mechanism, a water tank is provided on one side of the swing column, and foot pedals are provided on both the side of the bed away from the swing column and the side of the bed away from the water tank. An upper slide and a middle slide are arranged sequentially on the upper part of the bed, and a wire conveying part is provided on the side of the swing column away from the water tank.

[0014] Compared with existing technologies, the advantages of this utility model are: 1. This device adopts automated wire feeding. The drive motor provides power, which is transmitted to the transmission slider through the synchronous belt and drive connection component. Finally, it drives the wire drawing clamp assembly to automatically move the molybdenum wire. There is no need for manual dragging of the molybdenum wire, which not only reduces the labor intensity of operators, but also avoids the problems of molybdenum wire deviation and damage caused by manual operation, thus improving the wire feeding efficiency.

[0015] 2. The device uses ball bearing guides as guiding elements, combined with synchronous belts and synchronous pulleys to ensure that the linear motion of the wire drawing clamp assembly has extremely high positioning accuracy, stability and rigidity, with a short transmission chain, no backlash and rapid response.

[0016] 3. The device, through the design of the inclined part of the wire drawing clamp assembly and the wire drawing entry groove, allows the molybdenum wire to enter the clamp quickly and smoothly through the inclined guide structure, without the need for precise manual alignment. The upper clamp block is embedded in the installation notch of the lower clamp block, and the clamping structure is stable. It can be adapted to molybdenum wires of different diameters, and has a wider range of applications.

[0017] 4. The miniature inductive switches at both ends of the cover plate connection of the device are precisely matched with the wire drawing clamp assembly. When the wire drawing clamp assembly moves to the two ends of the stroke, the inductive switch immediately feeds back a signal and controls the drive motor to start, stop or reverse, avoiding component collision and molybdenum wire breakage caused by overtravel. This forms a dual protection of automated action and electronic limit, greatly reducing the risk of mechanism failure and extending the service life of the equipment. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1-6 As shown, a rocking-assisted molybdenum wire raising mechanism includes a bed 1, a rocking column 11 on one side of the bed 1, an upper cantilever 12 connected to the rocking column 11 and positioned horizontally above the bed 1, an upper molybdenum wire structure 2 parallel to the upper cantilever 12 on the upper side, a wire pulling clamp assembly 3 movably disposed within the upper molybdenum wire structure 2, and the wire pulling clamp assembly 3 axially moving along the length direction of the upper molybdenum wire structure 2 via a wire pulling drive mechanism 4.

[0027] Combination Figure 2 and Figure 5 As shown, the upper molybdenum wire structure 2 includes a wire drawing support 21 connected to the upper cantilever 12. A wire drawing cover plate 22 is provided on the upper side of the wire drawing support 21 along its width direction. An installation cavity 23 is located inside the wire drawing support 21, and an axially extending opening 24 communicating with the installation cavity 23 is provided between the wire drawing support 21 and the wire drawing cover plate 22. The wire drawing support 21 is designed with a built-in installation cavity 23, which encloses core transmission components such as the ball bearing guide 41 and the synchronous belt 67, forming a closed or semi-closed space. This effectively prevents the intrusion of electrolytic corrosion products and dust, improving the reliability and lifespan of the transmission system.

[0028] The wire drawing cover plate 22 has a vertically arranged cover plate connecting part 25 on the side near the wire drawing support 21. The lower end of the cover plate connecting part 25 is connected to one side of the opening 24, and the upper end of the cover plate connecting part 25, away from the wire drawing support 21, has a bending part 26. A movable space 27 is formed between the bending part 26 and the cover plate connecting part 25, and the movable space 27 is connected to the mounting cavity 23 through the opening 24. The design of the cover plate connecting part 25 and the bending part 26 significantly enhances the structural strength and bending stiffness of the wire drawing cover plate 22 itself, making it less prone to deformation when subjected to the torque brought by the movement of the clamp assembly, thus ensuring the stability of the movement. At the same time, the movable space 27 formed by the bending part 26 and the cover plate connecting part 25 provides the necessary precise guidance and limiting space for the axial movement of the wire drawing clamp assembly 3, while ensuring communication with the internal mechanism.

[0029] Specifically, the length of the bent portion 26 is less than the length of the cover plate connecting portion 25. The cover plate connecting portion 25, near the movable space 27, has miniature induction switches 28 at both ends that match the wire-drawing clamp assembly 3, and these miniature induction switches 28 are located above the opening 24. The placement of the miniature induction switches 28 at both ends of the cover plate connecting portion 25 and above the opening 24 reduces the risk of false triggering and damage, while also accurately detecting whether the clamp assembly has moved into position, achieving precise control.

[0030] Combination Figures 4-6 As shown, the wire-drawing clamp assembly 3 has a lower clamp block 31 located within the movable space 27. The lower clamp block 31 has an installation notch 32 on the side away from the cover plate connection portion 25. An upper clamp block 33 is located within the installation notch 32. An inclined portion 34 is located on the lower side of the upper clamp block 33, and a wire-drawing inlet groove 35 is formed between the inclined portion 34 and the lower clamp block 31. The lower clamp block 31 moves within the movable space 27, thus acting as a guide and ensuring the assembly moves along a predetermined trajectory without requiring an additional guide mechanism. The wire-drawing inlet groove 35 formed by the inclined portion 34 of the upper clamp block 33 and the lower clamp block 31 is a V-shaped or wedge-shaped structure. This design automatically guides the molybdenum wire into the bottom of the groove, achieving fast and accurate wire-drawing operation, simplifying manual operation, and improving efficiency.

[0031] The wire drawing drive mechanism 4 includes a ball bearing guide 41 axially disposed within the mounting cavity 23. The upper side of the ball bearing guide 41 extends through an opening 24 into the movable space 27 and contacts the cover plate connection part 25. A transmission slider 42 is movably connected to the ball bearing guide 41. The lower clamp block 31 has a slider connection notch 43 on the side near the cover plate connection part 25, which connects to the upper end of the transmission slider 42. The lower end of the transmission slider 42 is connected to the drive connection assembly 5. Using the ball bearing guide 41 as the guiding element has the advantages of low friction coefficient, smooth movement, high precision, and good rigidity, ensuring that the wire drawing clamp assembly 3 reciprocates accurately and without shaking. The transmission slider 42 is directly connected to the lower clamp block 31, and the drive connection assembly 5 directly transmits the power of the synchronous belt 67 to the transmission slider 42. This direct drive method reduces intermediate links, has a short transmission chain, good rigidity, fast response speed, and no backlash, ensuring positioning accuracy.

[0032] Specifically, a motor mounting seat 6 is provided on the inner side of the middle part of the wire drawing support 21, and a drive motor 61 connected to the motor mounting seat 6 is provided on the outer side of the middle part of the wire drawing support 21. The motor shaft 62 of the drive motor 61 passes through the wire drawing support 21 axially into the mounting cavity 23. A main synchronous pulley 63 connected to the motor shaft 62 is provided on the side of the motor mounting seat 6 away from the drive motor 61. Auxiliary pulleys 64 are provided side by side at both ends of the main synchronous pulley 63. Synchronous pulley mounting seats 65 are provided at both ends of the mounting cavity 23. A secondary synchronous pulley 66 is provided at the lower end of the synchronous pulley mounting seat 65. A synchronous belt 67 is wound around the main synchronous pulley 63, the auxiliary pulley 64 and the secondary synchronous pulley 66. The drive motor 61 is embedded in the mounting groove 29, and the motor shaft 62 extends directly into the mounting cavity 23 to drive the main synchronous pulley 63. This built-in design greatly saves axial space, making the entire molybdenum wire upper mechanism 2 very compact. At the same time, the synchronous belt 67 and the main synchronous pulley 63 and the auxiliary synchronous pulley 66 are used for transmission, ensuring precise synchronization of the transmission without slippage. The motor speed and the clamp movement distance are strictly corresponded. In addition, the auxiliary wheel 64 is used to tension and increase the wrap angle to prevent the synchronous belt 67 from slipping or jumping, ensuring smooth and reliable transmission.

[0033] Furthermore, the drive connection assembly 5 includes a connecting sheet metal 51 disposed at the lower end of the transmission slider 42 on the side away from the ball guide rail 41. The connecting sheet metal 51 has a vertical connecting portion 52 fixedly connected to the transmission slider 42. A horizontal connecting portion 53 is provided at the lower end of the vertical connecting portion 52. An oblique connecting portion 54 is provided between the horizontal connecting portion 53 and the vertical connecting portion 52. A fixing plate 55 connected to the synchronous belt 67 is provided at the end of the horizontal connecting portion 53 away from the oblique connecting portion 54. The design of the vertical connecting portion 52, the oblique connecting portion 54, and the horizontal connecting portion 53 of the connecting sheet metal 51 is a very ingenious avoidance structure. It allows the fixing plate 55 of the synchronous belt 67 to avoid the space below the ball guide rail 41 and the transmission slider 42 and to connect from the side. This solves the problem of power transmission between components with different axes in a compact space. At the same time, the use of sheet metal structure ensures connection rigidity while achieving lightweighting, reducing the inertia of moving parts, and facilitating rapid start-stop and precise control of the motor.

[0034] like Figure 3 As shown, the wire drawing support 21 has a mounting groove 29 on the outer side of the middle part, the drive motor 61 is located in the mounting groove 29, and the end of the mounting groove 29 away from the drive motor 61 is provided with a cantilever fixing seat 30 connected to the upper cantilever 12.

[0035] like Figure 1 As shown, a water tank is provided on one side of the rocking column 11, and foot pedals 14 are provided on both the side of the bed 1 away from the rocking column 11 and the side of the bed 1 away from the water tank. The upper end of the bed 1 is provided with an upper slide 15 and a middle slide 16 in sequence, and the rocking column 11 is provided with a wire conveying part 17 on the side away from the water tank.

[0036] The principle of this embodiment is as follows: When the drive motor 61 is powered on, its motor shaft 62 drives the main synchronous pulley 63 in the mounting cavity 23 to rotate. The main synchronous pulley 63 transmits power to the auxiliary synchronous pulleys 66 at both ends through the synchronous belt 67 wrapped around it. At the same time, the auxiliary pulleys 64 on both sides of the main synchronous pulley 63 tension and guide the synchronous belt 67 to ensure smooth transmission. The synchronous belt 67 drives the transmission slider 42 to move through the drive connection assembly 5. The synchronous belt 67 is rigidly connected to the transverse connection part 53 of the connecting sheet metal 51 through the fixed pressure plate 55. When the synchronous belt 67 moves cyclically, the vertical connection part 52 of the connecting sheet metal 51 drives the transmission slider 42 to move axially linearly along the ball guide rail 41. The upper end of the transmission slider 42 is embedded in the lower clamp. The slider connection notch 43 of the sub-block 31 allows the entire wire drawing clamp assembly 3 to move synchronously within the movable space 27 when the slider moves. The molybdenum wire enters the clamp assembly through the wire drawing inlet groove 35 formed by the inclined part 34 of the upper clamp block 33 and the lower clamp block 31. The inclined part 34 is designed to facilitate the automatic introduction of the molybdenum wire. The clamp assembly moves along the length direction of the upper molybdenum wire structure 2 under the drive of the drive mechanism, realizing the axial transfer of the molybdenum wire and completing the wire feeding action. When the clamp assembly moves to both ends of the movable space 27, it will trigger the miniature induction switch 28 on the cover plate connection part 25. The induction switch feeds back a signal to the control system, controlling the drive motor to stop or reverse, realizing precise control of the stroke of the clamp assembly and avoiding overtravel.
