Description

Technical Field

[0001] This utility model relates to the field of wire EDM machine tools, and in particular to a protective wire EDM machine tool. Background Technology

[0002] Wire EDM machines, falling under the category of electrical discharge machining, operate on the principle that free positive ions and electrons accumulate in an electric field, quickly forming an ionized conductive channel. Wire EDM machines operate in a semi-open environment, which cannot control the spread of waste generated during cutting, causing environmental pollution. This not only poses a significant threat to the health of operators but also violates increasingly stringent environmental policies, thus necessitating protective measures for the machines.

[0003] A search revealed a Chinese patent publication number CN222448602U, which discloses a wire EDM machine tool with a combined protective device. This patent includes a machine tool body, a worktable located at the upper end of the machine tool body, a groove on one side of the machine tool body, a storage plate screwed and fixed inside the groove, an extension plate slidably connected inside the storage plate, a scissor-type lifting frame fixed to the side of the extension plate facing the machine tool body, and a telescopic rubber sleeve covering the outside of the scissor-type lifting frame. A fixing plate is screwed to the end of the scissor-type lifting frame away from the extension plate. This device includes a retractable protective device that does not occupy extra space. When the machine tool is not in use, the protective device can be directly unfolded to prevent dust accumulation on the machine tool worktable and facilitate operation. However, this device uses a lead screw pair for drive, which affects the speed of unfolding the protective device. Furthermore, existing wire EDM machines lack comprehensive protection measures for the sides and top, and unfolding the protective device is inconvenient, affecting the operator's control of the wire EDM machine tool. Additionally, since coolant is required during wire EDM, the complex structure is susceptible to liquid damage, making it inconvenient to use. Utility Model Content

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figure 1 — Figure 6As shown, a protective wire EDM machine tool includes a base 101. A frame 102 and a cutting table 103 are mounted on the top of the base 101. A wire EDM device is mounted on the frame 102, and a fixing assembly is mounted on the cutting table 103. The fixing assembly for the wire EDM device and the workpiece is prior art and will not be described in detail. A storage mechanism is mounted on the front side of the base 101. The storage mechanism includes a storage box 201, which is bolted to the front side of the base 101. Sliding grooves 202 are provided on both sides of the storage box 201 for storing... The box 201 is equipped with a first protective mechanism, which includes a lifting plate 301. The lifting plate 301 has sliders 302 connected to both sides by bolts. The sliders 302 are slidably connected in the slide groove 202. The side of the lifting plate 301 away from the sliders 302 is equipped with a folding mechanism to protect the top of the cutting table 103. The base 101 is equipped with a second protective mechanism on both sides to protect the sides of the cutting table 103. The second protective mechanism is equipped with a locking component.

[0027] In this embodiment, the side of the slider 302 away from the lifting plate 301 is bolted to a mounting block 203. The locking assembly includes an insert block 505, and a push-pull handle 506 is bolted to the front end of the insert block 505. By operating the push-pull handle 506, the operator can control the position of the insert block 505 within the mounting block 203. The insert block 505 is slidably connected to the mounting block 203. The second protective mechanism includes several sets of fixing blocks 501. A third rotating shaft 502 is rotatably connected within the fixing blocks 501. The third rotating shaft 502 has a socket that mates with the insert block 505. 504, the cross-sectional shape of the insert 505 and the socket 504 is rectangular, and the intersection of the diagonals of the rectangular cross-sections of the insert 505 and the socket 504 is located on the axis of the third rotating shaft 502. The third rotating shaft 502 is connected to the flip plate 503 by bolts. By setting the insert 505 and the socket 504, when the flip plate 503 is in a vertical state, the rectangular cross-sections of the socket 504 and the insert 505 are aligned, so that locking can be achieved. In this way, the insert 505 can be inserted into the socket 504 to lock the third rotating shaft 502 and the flip plate 503.

[0028] In this embodiment, the folding mechanism includes two first connecting blocks 401. The first connecting blocks 401 are bolted to the end of the lifting plate 301 away from the slider 302. A first rotating shaft 402 is rotatably connected to the inner side of the first connecting blocks 401. A connecting plate 403 is bolted to the first rotating shaft 402. Two second connecting blocks 404 are bolted to the connecting plate 403. A second rotating shaft 405 is rotatably connected to the inner side of the second connecting blocks 404. A support plate 406 is bolted to the second rotating shaft 405.

[0029] In this embodiment, the connecting plate 403 is U-shaped, and the connecting plate 403 and the support plate 406 are hollowed out according to the size of the frame 102 to ensure that the connecting plate 403 and the support plate 406 can form a complete protection during wire cutting, and will not interfere with the frame 102 and other components during movement.

[0030] In this embodiment, two mating blocks 104 are bolted to the top of the base 101. The top of the mating block 104 is provided with a groove. The mating block 104 cooperates with the free end of the support plate 406. When the support plate 406 is unfolded, its free end is inserted into the groove of the mating block 104 to avoid the support plate 406 and the connecting plate 403 from sliding due to external force, which would affect the wire cutting operation.

[0031] In this embodiment, a sealing plate 303 is bolted to the end of the lifting plate 301 away from the slider 302. The sealing plate 303 is L-shaped and fills the gap between the lifting plate 301 and the connecting plate 403, forming a comprehensive protective structure. An observation window 304 is bolted to the lifting plate 301.

[0032] Working principle: In the initial state of use, the folding mechanism is folded, and the lifting plate 301 and the folding mechanism are together inside the storage box 201. The flipping plate 503 is in a low position. The operator fixes the workpiece to be wire-cut on the cutting table 103, then pulls the lifting plate 301 out of the storage box 201. At the same time, the push-pull handle 506 is controlled to position the insert block 505 on the outer side of the mounting block 203. When the lifting plate 301 is raised to the highest point, the insert block 505 is inserted into the corresponding insertion hole 504. The connecting plate 403 and the support plate 406 are unfolded, so that the free end of the support plate 406 is inserted into the docking block 104. The lifting plate 301, the connecting plate 403, and the support plate 406 are then connected. The three components (06, 506, 507, 508, 509, 5000) form a continuous protective cover in an inverted U-shape. Then, pull out the push-pull handles 506 one by one, while flipping up the rotating plate 503. When the rotating plate 503 is flipped to the high position, push the push-pull handles 506 to make the insert block 505 return to the insertion hole 504. This completes the protective measures. Start the wire cutting device to perform wire cutting operations. The operator can observe the internal processing through the observation window 304. The safety is high. After the processing is completed, the above operation is reversed to perform the next wire cutting operation. When the device is not used for a long time, the first protection and the second protection can be set to the protection state to prevent dust from falling on the cutting table 103, which can also play a certain protective role.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
