Technical Field

[0001] This utility model belongs to the field of wire feeding devices, specifically, it relates to a wire cutting automatic wire threading device for fixing the guide tube of the eyelid and lowering the wire. Background Technology

[0002] In existing automated wire EDM threading devices, the upper eyelid typically moves up and down with the guide tube to guide and thread the molybdenum wire. However, the upper eyelid is prone to wear and gaps during long-term repetitive movement, leading to decreased guiding accuracy and affecting the stability and precision of the threading process. Furthermore, because the upper eyelid component wears quickly, the equipment requires frequent maintenance and parts replacement, increasing operating costs and downtime, making it difficult to meet the demands of high-precision, high-stability wire EDM processing.

[0003] In view of this, this utility model is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a wire cutting automatic wire threading and guide wire feeding device for fixing the eye membrane, which solves the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: The wire cutting automatic wire feeding device for upper eyelid fixation guide tube descent includes: a machine head with a receiving space, an upper eyelid installed inside the upper part of the machine head, a guide nozzle provided below the machine head, and an upper eyelid fixation tube located in the receiving space fixedly installed on one side of the guide nozzle. A sliding frame is slidably connected within the accommodating space. An upper wire feeding module and an upper wire clamping mechanism are provided above the sliding frame. A descending guide wire tube is connected below the sliding frame. The upper fixed eye membrane tube and the descending guide wire tube are concentrically arranged. The upper wire feeding module and the upper wire clamping mechanism are located between the upper fixed eye membrane tube and the descending guide wire tube.

[0006] Optionally, an upper guide nozzle is installed above the head, and the upper fixed eye membrane tube is embedded and fixed in the inner hole of the upper guide nozzle.

[0007] Optionally, the upper wire feeding module includes a wire feeding wheel rotatably connected within a sliding frame, and a servo motor is fixedly connected below the sliding frame. The output end of the servo motor passes through the sliding frame and is connected between the wire feeding wheel.

[0008] Optionally, the upper wire clamping mechanism includes a stepper motor fixedly connected to one side of the sliding frame, a screw fixedly connected to the output end of the stepper motor, a slider slidably connected inside the sliding frame, and a wire clamping wheel rotatably connected to one side of the slider, which is opposite to the upper wire feeding wheel.

[0009] Optionally, the guide tube lowering mechanism includes a first motor below the machine head, the output end of the first motor passes through the bottom of the machine head and is connected to a first synchronous pulley located in the receiving space, a second synchronous pulley is fixedly connected to the side of the receiving space near the lower guide rail, a synchronous belt is provided between the first synchronous pulley and the second synchronous pulley, a clamping member is fixedly connected to one side of the synchronous belt, and the clamping member is fixedly connected to the sliding frame.

[0010] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time: This invention effectively avoids the wear and gap problems caused by the up-and-down movement of the upper eyelid tube in traditional wire threading by setting an upper fixed eyelid tube, a sliding frame, and a descending guide wire tube within the machine head's accommodating space. An upper wire feeding module and an upper wire clamping mechanism are configured on the sliding frame, ensuring the upper fixed eyelid tube and the descending guide wire tube are arranged concentrically. The upper wire feeding module and the upper wire clamping mechanism are located between the two. This achieves stable guidance and smooth wire threading of the molybdenum wire, significantly improving threading accuracy and success rate, while reducing equipment maintenance costs and failure rates, and enhancing the overall stability and service life of the machine.

Detailed Implementation

[0015] The present invention will now be described in further detail with reference to the accompanying drawings.

[0016] Please see Figure 1As shown, this embodiment provides a wire cutting automatic wire threading upper eyelid fixation guide tube descent and wire feeding device, including a machine head 1 with a receiving space, an upper eyelid 2 installed inside the upper part of the machine head 1, a guide nozzle 3 provided below the machine head 1, and an upper fixation eyelid tube 4 located in the receiving space fixedly provided on one side of the guide nozzle 3. A sliding frame 5 is slidably connected within the accommodating space. An upper wire feeding module and an upper wire clamping mechanism are positioned above the sliding frame 5, and a descending wire guide tube 6 is connected below the sliding frame 5. The upper fixed eyelid tube 4 and the descending wire guide tube 6 are concentrically arranged, with the upper wire feeding module and the upper wire clamping mechanism located between them. By arranging the upper fixed eyelid tube 4, sliding frame 5, descending wire guide tube 6, upper wire feeding module, and upper wire clamping mechanism within the accommodating space of the machine head 1, and ensuring that the upper fixed eyelid tube 4 and the descending wire guide tube 6 are concentrically arranged, with the upper wire feeding module and the upper wire clamping mechanism located between them, this solution effectively avoids the gap and wear problems caused by the up-and-down movement of the traditional upper eyelid 2 during wire threading. This ensures stable guidance of the molybdenum wire during feeding and threading, improves threading accuracy, and thus significantly enhances the overall processing reliability and service life of the device.

[0017] In this embodiment, the upper fixed eye membrane tube 4 is embedded and fixed within the inner hole of the upper guide nozzle 3. By fixing the upper fixed eye membrane tube 4 in the inner hole of the guide nozzle 3 in an embedded manner, this solution can ensure the stability of the eye membrane tube's position during operation, avoiding guide deviations caused by loosening or displacement. This ensures that the descending guide wire tube 6 can always maintain coaxial guidance with the upper fixed eye membrane tube 4, thereby further improving the accuracy and stability of the wire threading process, while also reducing the difficulty of assembly and maintenance.

[0018] In this embodiment, the upper wire feeding module includes a wire feeding wheel 8 rotatably connected within a sliding frame 5. A servo motor is fixedly connected below the sliding frame 5, and the output end of the servo motor passes through the sliding frame 5 and connects to the wire feeding wheel 8. By rotatably connecting the wire feeding wheel 8 within the sliding frame 5 and placing the servo motor below the sliding frame 5, with the output end of the servo motor directly connecting to the wire feeding wheel 8 through the sliding frame 5, this solution enables precise control and stable drive of the wire feeding wheel 8, allowing the molybdenum wire to enter the descending guide tube 6 at a smooth and uniform speed. This reduces wire breakage or threading failures caused by unstable wire feeding, improving wire feeding efficiency and reliability.

[0019] In this embodiment, the upper wire clamping mechanism includes a stepper motor fixedly connected to one side of the sliding frame 5. A screw 9 is fixedly connected to the output end of the stepper motor. A slider 10, which is threadedly connected to the screw 9, is slidably connected inside the sliding frame 5. A wire clamping wheel 11, which is opposite to the upper wire feeding wheel 8, is rotatably connected to one side of the slider 10. By fixing the stepper motor to one side of the sliding frame 5 and using the screw 9 at its output end to drive the slider 10 to move, thereby driving the wire clamping wheel 11 to engage with the wire feeding wheel 8, this solution can achieve double-wheel clamping of the molybdenum wire, and the clamping force is controllable and stable. This effectively reduces the vibration of the molybdenum wire during the wire feeding process, ensures the straightness of the molybdenum wire and the success rate of wire threading, thereby improving the overall working performance of the device.

[0020] In this embodiment, the wire guide tube lowering mechanism includes a first motor below the machine head 1. The output end of the first motor passes through the lower part of the machine head 1 and is connected to a first synchronous pulley 12 located in the receiving space. A second synchronous pulley 13 is fixedly connected to the side of the receiving space near the lower guide rail. A synchronous belt 14 is provided between the first synchronous pulley 12 and the second synchronous pulley 13. A clamping member 15 is fixedly connected to one side of the synchronous belt 14, and the clamping member 15 is fixedly connected to the sliding frame 5. By setting the first motor below the machine head 1 and utilizing the cooperation of the first synchronous pulley 12, the second synchronous pulley 13 and the synchronous belt 14, and the fixed connection between the clamping member 15 on one side of the synchronous belt 14 and the sliding frame 5, this solution can drive the sliding frame 5 and the lowering wire guide tube 6 to descend smoothly in the vertical direction, ensuring the straightness and accuracy of the wire guide tube during the movement, while preventing damage to the workpiece or mechanism due to excessive descent, thereby improving the safety and reliability of the wire threading process.
