Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medium-speed wire cutting, in particular to a cleaning-free processing end of a medium-speed wire electric spark wire cutting machine. Background Art
[0002] Medium-speed wire cutting is an EDM technology that uses the principle of electric pulse discharge to generate high-temperature melting and vaporized metal on the workpiece through molybdenum wire or other electrode wire, thereby achieving material cutting. This technology is carried out in an insulating liquid (usually deionized water or a special cutting fluid). The workpiece is not contacted during the processing, so no mechanical stress and deformation are generated. It is suitable for the processing of thin-walled and fine parts. Medium-speed wire cutting has the advantages of high precision, high efficiency and good surface quality. It can achieve micron-level processing accuracy and is suitable for cutting various complex shapes and fine structures. It is widely used in mold manufacturing, precision machinery, aerospace, medical equipment and electronic manufacturing, and can process almost all conductive materials, including cemented carbide, titanium alloy and aluminum alloy.
[0003] At present, the medium-speed wire EDM includes an upper processing arm and a lower processing arm. The molybdenum wire is output by the wire output mechanism of the upper processing arm, passes through the workpiece and then reaches the wire feeding mechanism of the lower processing arm. The wire feeding mechanism can pull the molybdenum wire through the workpiece continuously. However, since the current wire feeding mechanism on the lower processing arm is exposed to the outside for a long time, impurities are easily accumulated and need to be cleaned frequently, which increases the maintenance cost of the equipment.

[0027] Embodiment 1:
[0028] As Figures 1 to 5 shown, this embodiment provides a cleaning-free processing end of a middle-wire electrical discharge wire cutting machine, including an upper processing arm 1 and a lower processing arm 2. An wire feeding mechanism is provided on the upper processing arm 1, and a wire feeding mechanism 3 is provided on the lower processing arm 2. The wire feeding mechanism 3 can refer to the wire feeding mechanism on the processing arm of a middle-wire electrical discharge wire cutting machine or other traditional wire cutting machines in the prior art. Among them, the workpiece is processed between the upper processing arm 1 and the lower processing arm 2.
[0029] In the embodiment of the present disclosure, a driver 4 and a sliding seat 5 slidably arranged along the length direction of the lower processing arm 2 are provided on the lower processing arm 2. Preferably, the driver 4 uses a driving cylinder. It should be understood that the driver 4 can also use a structure such as a motor配合丝杆滑块 (the description here seems incorrect, assuming it should be motor配合丝杆 and slider) that can achieve translation. In this embodiment, the case where the driver 4 uses a driving cylinder is taken as an example.
[0030] In the embodiment of the present disclosure, the wire feeding mechanism 3 is arranged on the sliding seat 5, and a protection cavity 6 is provided on the lower processing arm 2. The protection cavity 6 is formed by a protective cover 7 and the lower processing arm 2. Specifically, the lower processing arm 2 is L-shaped, the protective cover 7 is 冂-shaped (this shape description seems incorrect, assuming it should be U-shaped), the protective cover 7 is detachably connected to the lower processing arm 2, and the protection cavity 6 is formed between the two. The rear end of the protective cover 7 is closely attached to the lower processing arm 2. Through this setting, the L-shaped lower processing arm 2 and the U-shaped protective cover 7 are seamlessly and closely attached, forming a protection cavity 6 that is closed at the rear end and allows the wire feeding mechanism to pass through at the front end, reducing the influence of impurities and pollutants in the external environment on the wire feeding mechanism, and thus better protecting the wire feeding mechanism. In addition, the protective cover 7 is detachably connected to the lower processing arm 2, making the disassembly and installation process simple.
[0031] Secondly, the driver 4 is located in the protection cavity 6, which can effectively protect the driver 4.
[0032] Under the drive of the driver 4, the sliding seat 5 has a standby position retracted into the protection cavity 6 and a working position extending out of the protection cavity 6. Through this setting, by providing the protection cavity 6 and the sliding seat 5 on the lower processing arm 2, the wire feeding mechanism 3 is retracted into the protection cavity 6 in the standby state, avoiding the wire feeding mechanism 3 being exposed for a long time, and thus avoiding the accumulation of impurities on the wire feeding mechanism. Secondly, the frequency of cleaning and maintenance is effectively reduced, and further the maintenance cost of the equipment is reduced. In addition, the setting of the protection cavity 6 reduces the problems of wear and corrosion caused by the long-term exposure of the wire feeding mechanism 3, extends the service life of the wire feeding mechanism and related components, and improves the overall reliability of the equipment.
[0033] In the embodiment of the present disclosure, two fixed plates 8 are provided on the lower processing arm 2 at intervals, and the fixed plates 8 include a horizontal plate portion 80 and a vertical plate portion 81. The horizontal plate portion 80 is bolted to the lower processing arm 2, and the front and rear ends of the driver 4 are respectively connected to the vertical plate portions 81 of the two fixed plates 8, thereby providing a stable, reliable and easy-to-maintain fixed structure, which not only enhances the stability and driving accuracy of the equipment, but also extends the service life of the equipment.
[0034] The lower processing arm 2 is equipped with at least two sliders 9 located in front of the driver 4. These sliders 9 are equipped with slide rails 10. The sliding seat 5 is fixed to the front end of the slide rails 10, and the rear end of the sliding seat 5 is connected to the drive rod of the driver 4. The design of the sliders 9 and slide rails 10 provides precise guidance, ensuring the smoothness and positioning accuracy of the sliding seat 5 during movement. Furthermore, the at least two sliders 9 provide multi-point support for the movement of the sliding seat 5, dispersing mechanical stress and reducing the impact of single-point loads on the sliding mechanism, thereby enhancing the structural stability and durability of the entire device.
[0035] In the disclosed embodiment, the lower processing arm 2 is provided with a first step 20 and a second step 21 along its distal end. The upper end surface of the first step 20 is higher than the upper end surface of the second step 21. The driver 4 is mounted on the first step 20, and the slider 9 is mounted on the second step 21. The first step 20 is provided with a groove 22 for the slide rail 10 to pass through along the moving direction of the slide rail 10. The design of steps of different heights effectively utilizes space, avoids interference between components, and improves the compactness of the overall structure. In addition, compared to the traditional sliding structure in which the slide rail is fixed and the slider moves, the structure in which the slider is fixed and the slide rail moves is adopted in this embodiment, which helps to reduce the space occupied by the mechanism on the lower processing arm 2.
[0036] Furthermore, the portions of the slider 9 and the slide rail 10 that are not blocked by the slide seat 5 are all located in the protective cavity 6, thereby protecting the entire sliding mechanism and extending the service life of the mechanism.
[0037] Example 2:
[0038] like Figure 6 As shown, the difference between this embodiment and embodiment 1 is that a cover plate 70 is hinged on the upper side of the front end of the protective cover 7. When the wire feeding mechanism is pushed out of the protective cover 7, the cover plate 70 is pushed upward, and when the wire feeding mechanism is retracted into the protective cover 7, the cover plate 70 automatically falls under the action of gravity, closing the front end of the protective cavity 6.
[0039] Furthermore, a torsion spring is provided at the hinged position between the cover plate 70 and the protective cover 7 to ensure that the cover plate 70 stably closes the front end of the protective cavity 6 .

Although not expressly stated herein, those skilled in the art will understand that the present application requires various reasonable changes, improvements, and modifications to the embodiments.

[0041] Furthermore, it should be understood that in the foregoing descriptions of the embodiments of this application, in order to facilitate understanding of a feature and to simplify this application, this application combines various features into a single embodiment, figure, or description thereof. However, this does not mean that the combination of these features is required.
