Technical Field

[0001] This utility model relates to the field of cutting equipment technology, specifically to an electrical discharge wire cutting machine. Background Technology

[0002] Wire EDM uses a continuously moving fine metal wire as an electrode to remove metal from a workpiece through pulsed spark discharge, thus shaping it. Chinese Patent CN222448605U discloses a traveling mechanism for a wire EDM machine, including a worktable and a transverse guide plate on the front side of the vertical plate, which is slidably connected to both sides of the vertical plate via side plates. This traveling mechanism not only allows the cutting components to move forward, backward, left, right, and up and down, enabling it to cut complex workpieces with higher precision and better results, but also automatically cleans debris from the machining groove, saving workers' cleaning time and improving processing efficiency.

[0003] However, the above-mentioned publicly available solutions have the following shortcomings: when the cutting component cuts the workpiece, it will generate flying electric sparks, which are metal particles, which can easily pose a danger to the workers. Moreover, the metal fragments falling onto the workpiece will also interfere with the cutting work and reduce the cutting efficiency. Utility Model Content

[0017] Example 1, as Figures 1 to 4 As shown, the present invention proposes an electrical discharge wire cutting machine, including an electrical discharge machine body 1, a lifting assembly, a clamping assembly, and a bracket 203; the electrical discharge machine body 1 has a processing cavity 101, which is located below the cutting assembly; the lifting assembly is adjustablely disposed in the processing cavity 101, and the lifting assembly consists of two sets of first driving components mounted on the electrical discharge machine body 1 and a mounting frame, which is driven by the two sets of first driving components to adjust along the height direction of the processing cavity 101; the clamping assembly is detachably mounted on the mounting frame; the bracket 203 is detachably mounted on the lifting assembly, and a universal cooling pipe is installed on the bracket 203, the output end of which corresponds to the clamping assembly and is connected to an external coolant supply mechanism.

[0018] The clamping assembly includes a reinforcing seat 401 mounted on the support frame 4. The reinforcing seat 401 is cross-shaped and detachably connected to the mounting bracket. A second driving member is disposed in the mounting groove on the support frame 4. Two sets of clamping seats 5 are provided. The two sets of clamping seats 5 are driven by the second driving member to adjust towards or away from each other along the top of the support frame 4. The second driving member consists of a bidirectional threaded rod rotatably connected in the mounting groove and a second stepper motor that is driven by the bidirectional threaded rod. The bottom end of the clamping seat 5 is slidably connected to the mounting groove and the bottom end of the clamping seat 5 is threadedly connected to the bidirectional threaded rod.

[0019] Furthermore, the first driving component consists of a first threaded rod rotatably connected to the body 1 of the electric discharge cutting machine and a first stepper motor that is drivenly connected to the first threaded rod, and the mounting bracket is installed between the two sets of first threaded rods.

[0020] Furthermore, the mounting frame includes a support base 2 and lifting rods 202; two sets of support rods 201 are symmetrically mounted on the support base 2, the support rods 201 are slidably connected to the processing cavity 101, two sets of slide rails are symmetrically opened on the side wall of the processing cavity 101, and the support rods 201 are slidably connected to the slide rails; two sets of lifting rods 202 are provided, the two sets of lifting rods 202 are symmetrically mounted on the support base 2, and the end of the lifting rod 202 away from the support base 2 extends to the outside of the processing cavity 101 and is threadedly connected to the first threaded rod; the bracket 203 is mounted on one set of lifting rods 202, and the docking seat 3 is mounted on the top of the support base 2.

[0021] Furthermore, the support base 2 in the mounting frame is provided with a docking assembly at its top. The reinforcing base 401 is detachably connected to the mounting frame through the docking assembly. The reinforcing base 401 is provided with a docking interface 402. Two sets of docking interfaces 402 are provided at the top of the docking interface 402 and on the reinforcing base 401. The docking assembly includes a docking seat 3, a slide 301, and a limiting plate 303. The docking seat 3 is installed on the support base 2 and is inserted into the docking interface 402. Two sets of slides 301 are provided, and the two sets of slides 301 slide. The inner wall of the connecting dock 3 is connected, and the side wall of the slide 301 is provided with a guide block. The guide block is slidably connected to the slide groove of the inner wall of the connecting dock 3. The guide block can prevent the slide 301 from separating from the connecting dock 3. An elastic element 302 is installed between the two sets of slides 301. The elastic element 302 is a spring. The limiting plate 303 is installed on the side wall of the slide 301. The side wall of the connecting dock 3 is symmetrically provided with two sets of sockets. The limiting plate 303 is slidably connected to the sockets. The two sets of limiting plates 303 respectively abut against the corresponding limiting grooves 403.

[0022] In this embodiment, the second driving component adjusts the two sets of clamping seats 5 to move closer to each other along the top of the support frame 4, clamping the workpiece between the two sets of clamping seats 5 to prevent displacement and interference with cutting. The first driving component drives the two sets of lifting rods 202 to move down along the processing cavity 101, moving the clamping assembly into the processing cavity 101 to prevent the electric sparks generated during cutting from splashing outside the processing cavity 101 and causing danger. The cutting assembly on the EDM machine body 1 is started to cut the workpiece. At the same time, coolant is supplied to the universal cooling pipe through the external coolant supply mechanism, and coolant is sprayed out to the output end of the cutting assembly through the universal cooling pipe to cool the electric sparks and the workpiece, flushing the generated metal particles into the processing cavity 101. The coolant that has absorbed heat and the metal particles are discharged along the drain pipe of the processing cavity 101. After completion, the metal particles accumulated on the clamping assembly are flushed away. Then, the first driving component drives the two sets of lifting rods 202 to rise along the processing cavity 101, so that the clamping assembly moves to a suitable height. The two sets of sliding blocks 301 slide close along the inner wall of the docking seat 3, so that the elastic element 302 is compressed. At the same time, the two sets of limiting plates 303 slide close along the insertion port until the limiting plates 303 are housed inside the docking seat 3. At this time, the limiting plates 303 no longer abut against the limiting groove 403. The reinforcing seat 401 can slide upward along the docking seat 3, thereby quickly separating the support frame 4 from the support seat 2. The inner wall of the processing cavity 101 can be thoroughly cleaned to avoid impurities remaining. The wastewater from the cleaning is discharged through the drain valve on the side wall of the EDM machine body 1. The clamping assembly is easy and quick to disassemble, which is convenient for daily maintenance and replacement.

[0023] Example 2, as Figure 1 As shown, the present invention proposes an electrical discharge wire cutting machine, which, compared with the first embodiment, has an inclined bottom surface of the processing chamber 101, and a drain pipe is installed at the lower end of the bottom surface of the processing chamber 101, so that the coolant can carry the metal particles generated by cutting to the lower position and discharge them along the drain pipe.

[0024] Furthermore, the drain pipe output end is connected to a guide pipe 102, and the guide pipe 102 output end is connected to a recovery mechanism 103. The recovery mechanism 103 consists of a box installed on the side wall of the EDM machine body 1 and a filter screen 104 that can be detachably installed inside the box. The box output end is connected to an external coolant supply mechanism through a pipe and a pump body, and a cooling component is provided in the middle of the pipe.

[0025] In this embodiment, the coolant and metal particles sprayed from the universal cooling pipe towards the cutting component flow towards the lower end in the processing chamber 101 and flow into the recovery mechanism 103 along the guide pipe 102. After being filtered by the filter screen 104, they gather at the bottom of the box. The filtered and recovered coolant can be pumped to the cooling component for heat dissipation and then to the external coolant supply mechanism for reuse, avoiding waste. The cooling component is existing technology, which those skilled in the art can clearly understand. By opening the sealed door on the side wall of the box, the filter screen 104 can be removed and the filtered impurities can be collected and processed.

[0026] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
