Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire cutting machine technology, and in particular to an automatic wire feeding structure with a moving wire spool. Background Technology
[0002] Wire EDM is a machining method that uses a moving metal wire (molybdenum wire, copper wire, or alloy wire) as the electrode wire. Pulsed electric sparks between the electrode wire and the workpiece generate high temperatures that melt or vaporize the metal, creating a kerf and thus cutting the part. When the electrode wire needs to pass through the workpiece, the wire end must first be detached from the wire spool, then the wire is passed through the workpiece, and finally the wire end is reconnected to the wire spool to form a closed loop. However, during machining, the electrode wire may be stretched or worn, causing the wire end to be too long or too short relative to the wire clamp on the wire spool. If the wire is too long, it will become loose after connection; if it is too short, it will not be able to connect to the wire spool.
[0003] Existing wire EDM machines can automatically disconnect, thread, and splice electrode wires. When the electrode wire is too long or too short, they adjust the wire length through a dynamic wire storage adjustment mechanism to change the position of the wire end relative to the wire spool clamp, thus achieving splicing. There are other research and development directions regarding the automatic wire splicing structure. Those skilled in the art hope for another automatic wire splicing structure that can also automatically splice wires when they are too long or too short. Utility Model Content
[0004] The main purpose of this invention is to propose a movable wire-jointing structure for wire spools, providing another structure that can automatically join wires when the electrode wire is too long or too short.
[0005] To achieve the above objectives, this utility model proposes a movable wire-spool automatic wire-connecting structure, including a base. The base is provided with a wire spool assembly, a clamping mechanism, an upper wire-threading mechanism, and a lower wire-threading mechanism arranged in sequence. The wire spool assembly, the clamping mechanism, the upper wire-threading mechanism, and the lower wire-threading mechanism form a wire-feeding path. The clamping mechanism is used to clamp and feed the electrode wire. A processing station is provided between the upper wire-threading mechanism and the lower wire-threading mechanism.
[0006] The wire spool assembly includes a movable base, a compensation moving mechanism, a wire spool, a wire feeding motor, and an angle detection device. The movable base is slidably connected to the base, and the compensation moving mechanism is drivenly connected to the movable base. The compensation moving mechanism can drive the movable base to move in a direction closer to or away from the wire feeding mechanism and control the moving distance of the movable base. The wire spool is rotatably connected to the movable base and is provided with a wire clamp for clamping or releasing the wire end of the electrode wire. The wire feeding motor is fixedly connected to the movable base and drivenly connected to the wire spool. The angle detection device can detect the rotation angle of the wire feeding motor.
[0007] The automatic wire feeding structure with movable wire spool also includes a wire end detection component. The conveying path includes a wire end detection position. The wire end detection component is located beside the wire end detection position. The wire end detection component is used to detect whether the wire end has reached the wire end detection position. The wire end detection component is signal connected to the wire feeding motor, the angle detection device, and the compensation moving mechanism. The wire end detection component, the wire feeding motor, the angle detection device, and the compensation moving mechanism work together to change the position of the wire spool so that the wire end of the cut electrode wire is connected to the wire clamping member.
[0008] During wire splicing, the wire feeding motor drives the wire drum to rotate and feed the electrode wire. An angle detection device detects the angle of the wire drum, a wire end detection component detects the position of the wire end, and a compensation movement mechanism determines the position of the wire drum. Based on the position of the wire end, the angle of the wire drum, and the position of the wire drum, the distance difference between the wire end and the clamping component can be determined. Then, the compensation movement mechanism moves the moving base and the wire drum a compensation distance, and the wire drum rotates. The clamping component rotates to the wire splicing angle, and the wire end moves precisely to the position of the clamping component, clamping the wire end and achieving connection between the wire end and the clamping component. This invention, through the cooperation of the wire end detection component, the wire feeding motor, the angle detection device, and the compensation movement mechanism, can move the position of the wire drum for compensation, ensuring that the wire end of the electrode wire aligns with the moved clamping component, thus achieving automatic wire splicing even when the electrode wire is too long or too short.

The detection drive unit is disposed on the base, and the conductive detection element is tractively connected to the detection drive unit. The detection drive unit can drive the conductive detection element into or away from the conveying path. When the conductive detection element enters the conveying path, it can contact the wire end to detect the wire end. The wire end detection assembly can detect the wire end through the contact between the conductive detection element and the wire end. The detection drive unit drives the conductive detection element into the conveying path. After the wire end touches the conductive detection element, the conductive detection element conducts electricity, thereby detecting the wire end. After detection, the detection drive unit drives the conductive detection element away from the conveying path, and the electrode wire can move.
[0012] Preferably, the automatic wire splicing structure with movable wire spool further includes a transversely arranged wire guide tube, which is located between the wire spool and the lower wire feeding mechanism, and is positioned to match the wire clamping member. The wire guide tube can guide and restrict the position of the electrode wire, allowing the electrode wire and wire end to be conveyed to the wire spool assembly.

[0031] like Figures 1 to 9 As shown, an automatic wire feeding structure with a moving wire spool includes a base 1. The base 1 has a wire spool assembly, a clamping mechanism 3, an upper wire threading mechanism 4, and a lower wire threading mechanism 5 arranged sequentially. The wire spool assembly, clamping mechanism 3, upper wire threading mechanism 4, and lower wire threading mechanism 5 form a transport path for the electrode wire 8. The clamping mechanism 3 clamps and transports the electrode wire 8. A processing station is provided between the upper wire threading mechanism 4 and the lower wire threading mechanism 5. The clamping mechanism 3 can transport the electrode wire 8, and in conjunction with the wire spool assembly, it maintains a certain tension on the electrode wire 8 during transport. The processing station between the upper wire threading mechanism 4 and the lower wire threading mechanism 5 can accommodate a workpiece. The electrode wire 8 passes through the upper wire threading mechanism 4 and the lower wire threading mechanism 5 to perform wire cutting on the workpiece. The structures of the clamping mechanism 3, the upper wire threading mechanism 4, and the lower wire threading mechanism 5 can refer to the structures of existing technologies and will not be described in detail here.
[0032] The wire drum assembly includes a movable base 21, a compensating movement mechanism 22, a wire drum 23, a wire feeding motor, and an angle detection device. The movable base 21 is slidably connected to the base 1. The compensating movement mechanism 22 is drivenly connected to the movable base 21. The compensating movement mechanism 22 can drive the movable base 21 to move in a direction closer to or away from the wire feeding mechanism 5 and control the moving distance of the movable base 21. The wire drum 23 is rotatably connected to the movable base 21. The wire drum 23 is provided with a wire clamping member 231 for clamping or releasing the wire head 81 of the electrode wire 8.

[0033] The automatic wire feeding structure with moving wire drum also includes a wire end detection component 6. The conveying path includes a wire end detection position. The wire end detection component 6 is located beside the wire end detection position. The wire end detection component 6 is used to detect whether the wire end 81 has reached the wire end detection position. The wire end detection component 6 is connected to the wire feeding motor, the angle detection device and the compensation moving mechanism 22. The wire end detection component 6, the wire feeding motor, the angle detection device and the compensation moving mechanism 22 work together to change the position of the wire drum 23 so that the wire end 81 of the cut electrode wire 8 is connected to the wire clamping member 231.
[0034] During wire feeding, the wire feeding motor drives the wire drum 23 to rotate and feed out the electrode wire 8. The angle detection device detects the angle of the wire drum 23, the wire end detection assembly 6 detects the position of the wire end 81, and the position of the wire drum 23 is determined by the compensation moving mechanism 22. Based on the position of the wire end 81, the angle of the wire drum 23, and the position of the wire drum 23, the distance difference between the wire end 81 and the wire clamping member 231 can be determined. Then, the compensation moving mechanism 22 drives the moving seat 21 and the wire drum 23 to move a compensation distance. If the electrode wire 8 is too short, refer to... Figures 1 to 3 Then the moving seat 21 and the wire spool 23 move towards the side closer to the lower wire threading mechanism 5. If the electrode wire 8 is too long, refer to... Figures 4 to 6 Then, the movable seat 21 and the wire drum 23 move away from the wire feeding mechanism 5, and the wire drum 23 rotates, causing the wire clamping member 231 to rotate to the wire receiving angle. The wire end 81 moves exactly to the position of the wire clamping member 231, and the wire clamping member 231 clamps the wire end 81, realizing the docking of the wire end 81 with the wire clamping member 231. Specifically, the compensation moving mechanism 22 can first drive the movable seat 21 and the wire drum 23 to move a compensation distance, and then the wire drum 23 rotates to dock with the wire end 81; or the wire drum 23 can first rotate to the docking angle, and then the compensation moving mechanism 22 can drive the movable seat 21 and the wire drum 23 to move a compensation distance to dock with the wire end 81; or the movement of the compensation moving mechanism 22 and the rotation of the wire drum 23 can be carried out synchronously.
[0035] This invention uses the cooperation of the wire end detection component 6, the wire feeding motor, the angle detection device and the compensation moving mechanism 22 to move the position of the wire drum 23 for compensation, so that the wire end 81 of the electrode wire 8 is connected to the wire clamping piece 231 after the movement, thereby realizing that the electrode wire 8 can be automatically connected even when it is too long or too short.
[0036] In some specific embodiments, reference is made to Figures 1 to 6 The yarn end detection component 6 is located on the side of the yarn spool assembly near the lower yarn threading mechanism 5. In other embodiments, refer to... Figure 7 The yarn end detection component 6 is located on the lower side of the upper yarn threading mechanism 4. The yarn end detection component 6 can be located on the side of the yarn spool 23 near the lower yarn threading mechanism 5, or on the lower side of the upper yarn threading mechanism 4. When the yarn end 81 moves to the position of the yarn end detection component 6, the yarn end 81 can be detected.
[0037] In some specific embodiments, reference is made to Figures 1 to 7 The thread detection component 6 is an infrared sensor, a photoelectric sensor, or a vision detector. The thread detection component 6 can detect the thread 81 through a non-contact detection method using an infrared sensor, a photoelectric sensor, or a vision detector.
[0038] In some specific embodiments, reference is made to Figure 8 and 9 The wire end detection assembly 6 includes a detection drive unit 61 and a conductive detection element 62. The detection drive unit 61 is mounted on the base 1. The conductive detection element 62 is connected to the detection drive unit 61 in a transmission manner. The detection drive unit 61 can drive the conductive detection element 62 into or away from the conveying path. When the conductive detection element 62 enters the conveying path, it can contact the wire end 81 to detect the wire end 81.
[0039] The wire end detection assembly 6 can detect the wire end 81 through contact between the conductive detection element 62 and the wire end 81. The detection drive unit 61 drives the conductive detection element 62 into the conveying path. After the wire end 81 touches the conductive detection element 62, the conductive detection element 62 conducts electricity, thus detecting the wire end 81. After detection, the detection drive unit 61 drives the conductive detection element 62 away from the conveying path, and the electrode wire 8 can move. The detection drive unit 61 can be a cylinder.
[0040] In some specific embodiments, the automatic wire splicing structure with movable wire spool further includes a transversely arranged wire guide tube 71, which is located between the wire spool 23 and the lower wire feeding mechanism 5, and is positioned to match the wire clamping member 231. The wire guide tube 71 can guide and restrict the position of the electrode wire 8, so that the electrode wire 8 and the wire end 81 are conveyed to the wire spool assembly.
[0041] In some specific embodiments, the wire clamp 231 is a spring sheet structure. The automatic wire splicing structure with movable wire spool also includes a guide tube drive mechanism 72. The guide tube drive mechanism 72 is connected to the guide tube 71 in a transmission manner. The guide tube drive mechanism 72 is connected to the compensation movement mechanism 22 in a signal manner. The guide tube drive mechanism 72 can drive the guide tube 71 to move closer to the wire clamp 231 to open the wire clamp 231 or move away from the wire clamp 231 to close the wire clamp 231.
[0042] The wire clamp 231 can adopt a spring-loaded structure. When the wire clamp 231 is at the origin angle position, the guide tube drive mechanism 72 drives the guide tube 71 to approach the wire clamp 231 and open it. The moving distance of the guide tube 71 driven by the guide tube drive mechanism 72 is determined according to the moving position of the wire spool 23. At this time, the wire end 81 can enter the wire clamp 231. Then, the guide tube drive mechanism 72 drives the guide tube 71 away from the wire clamp 231, and the wire clamp 231 resets and clamps the wire end 81 under the action of elasticity. The guide tube drive mechanism 72 can adopt a screw and nut motion module, a gear and rack motion module, or a synchronous pulley and synchronous belt motion module, etc. The spring-loaded wire clamp 231 can refer to the prior art. In this wire splicing method, the wire spool 23 can first rotate to the splicing angle and send out the electrode wire 8, while the clamping mechanism 3 does not send out the electrode wire 8 at first, and the electrode wire 8 is in a relaxed state. When the clamping member 231 is opened, the clamping mechanism 3 sends out the tensioned electrode wire 8 so that the wire end 81 enters the clamping member 231 to complete the wire splicing.
[0043] In some specific embodiments, reference is made to Figure 8 and Figure 9 The wire clamp 231 is movably connected to the wire drum 23. A return spring is connected between the wire clamp 231 and the wire drum 23. The moving seat 21 is also provided with a pressing drive mechanism. The pressing drive mechanism is matched with the position of the wire clamp 231. The pressing drive mechanism can press the wire clamp 231 to open the wire clamp 231, and the return spring can reset the wire clamp 231 to close.
[0044] The movable seat 21 is equipped with a pressing drive mechanism (not shown in the attached figure). When the wire clamp 231 is at the origin angle position, the pressing drive mechanism can press the wire clamp 231 to open it, allowing the wire end 81 to enter the wire clamp 231, while the guide tube 71 remains stationary. Then, the pressing drive mechanism releases the wire clamp 231, and the wire clamp 231 returns to its original position under the action of the return spring, clamping the wire end 81. The guide tube drive mechanism 72 can be a cylinder or the like. The pressing-type wire clamp 231 can refer to existing technology.
[0045] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
