Description

Technical Field

[0001] This utility model relates to the field of cutting machine tool technology, specifically a CNC wire electrical discharge machining (EDM) machine tool. Background Technology

[0002] Electrical discharge wire cutting, sometimes called wire cutting, works by using a continuously moving fine metal wire as an electrode to remove metal and cut the workpiece using pulsed spark discharge. Electrical discharge wire cutting is a type of special machining. Unlike traditional machining techniques that require mechanical force and energy to remove material, it primarily uses electrical energy to process materials. Therefore, electrical discharge wire cutting is not limited by material properties and can process materials of any hardness, strength, or brittleness, making it a very important process in modern machining.

[0003] In existing wire EDM technology, cooling is required at the cutting position. However, some debris and dust generated during the cutting process fall into the coolant reservoir at the bottom of the cutting machine along with the coolant. If not handled, the debris and coolant will be drawn back, which may block the pipes and affect normal circulating cooling. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a CNC wire electrical discharge machining tool.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses a CNC wire EDM machine tool, including a machine tool body. The machine tool body has a processing table and a cutting assembly located above the processing table inside. The bottom of the machine tool body has a recovery and filtration mechanism for collecting coolant. The recovery and filtration mechanism includes an inclined funnel located inside the machine tool body and below the processing table. The machine tool body has a liquid storage chamber located below the inclined funnel inside. The liquid storage chamber is connected to a slag collection screen located at the outlet of the inclined funnel via a detachable component. The outer end wall of the slag collection screen is provided with a push-pull handle.

[0007] As a preferred embodiment of this utility model, a liquid pump is installed at the bottom of the liquid storage chamber, and the inlet of the liquid pump is flush with the bottom wall of the liquid storage chamber.

[0008] As a preferred embodiment of this utility model, the outlet of the liquid pump is connected to a liquid extraction pipe extending to the cutting assembly, and the outlet of the liquid extraction pipe is connected to a cooling nozzle.

[0009] As a preferred technical solution of this utility model, the detachable component includes two horizontal support plates provided on the inner wall of the liquid storage chamber, the top of the horizontal support plates is provided with a guide groove, and the bottom two sides of the slag receiving net box are provided with guide rollers that match the guide groove.

[0010] As a preferred embodiment of this utility model, one end of the two horizontal support plates is connected to the same positioning plate, and the bottom end of the horizontal support plate is provided with a reinforcing rib connected to the inner wall of the liquid storage cavity.

[0011] As a preferred technical solution of this utility model, the machine tool body is provided with a slag discharge port located at the horizontal support plate. A protective door is connected to the slag discharge port via a rotating shaft. The protective door is locked to the machine tool body by a latch and has a handle.

[0012] As a preferred technical solution of this utility model, one side of the positioning plate is provided with a first magnet, and one end of the slag receiving mesh box is provided with a second magnet with a magnetic field different from that of the first magnet.

[0013] The beneficial effects of this utility model are:

[0014] In this type of CNC wire EDM machine, during the wire EDM process, coolant and debris enter the inclined funnel inside the storage chamber. Guided by the inclined funnel, the coolant and debris enter the slag collection box. The debris remains inside the slag collection box, while the coolant flows through the mesh of the slag collection box into the storage chamber. This facilitates the filtration of debris mixed in with the coolant, preventing debris from entering the storage chamber and causing blockages in the subsequent pipeline, thus ensuring normal circulation.

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] Example: Figure 1 , Figure 2 and Figure 3 As shown, this utility model discloses a CNC wire electrical discharge machining (EDM) machine tool, including a machine tool body 1. The machine tool body 1 has a machining table 2 and a cutting assembly 3 located above the machining table 2 inside. The bottom of the machine tool body 1 has a recovery and filtration mechanism 4 for collecting coolant. The recovery and filtration mechanism 4 includes an inclined funnel 401 located inside the machine tool body 1 and below the machining table 2. The machine tool body 1 has a liquid storage chamber 402 located below the inclined funnel 401 inside. A slag collection screen 404 located at the outlet of the inclined funnel 401 is connected to the liquid storage chamber 402 via a detachable assembly 403. The outer end wall of the slag collection box 404 is equipped with a push-pull handle 405. During the wire cutting process, coolant and debris enter the inclined funnel 401 inside the liquid storage chamber 402. Under the guidance of the inclined funnel 401, coolant and debris enter the interior of the slag collection box 404. The debris remains inside the slag collection box 404, while the coolant flows through the mesh of the slag collection box 404 into the interior of the liquid storage chamber 402. This facilitates the filtration of debris mixed in with the coolant, preventing debris from entering the interior of the liquid storage chamber 402 and causing blockages in the subsequent pumping into the pipeline, thus ensuring normal circulation.

[0022] The liquid storage chamber 402 is equipped with a liquid pump 5 at its bottom. The inlet of the liquid pump 5 is flush with the bottom wall of the liquid storage chamber 402. The outlet of the liquid pump 5 is connected to a liquid extraction pipe 6 that extends to the cutting assembly 3. The outlet of the liquid extraction pipe 6 is connected to a cooling nozzle. When the liquid pump 5 is working, it will draw the coolant inside the liquid storage chamber 402 into the liquid extraction pipe 6 and spray it out through the cooling nozzle to cool the cutting position.

[0023] The detachable component 403 includes two horizontal support plates 4031 on the inner wall of the liquid storage chamber 402. The top of the horizontal support plate 4031 is provided with a guide groove 4032. The bottom sides of the slag receiving mesh box 404 are provided with guide rollers 4033 that match the guide groove 4032. The cooperation of the guide groove 4032 and the guide rollers 4033 can quickly position the slag receiving mesh box 404 and accurately move the slag receiving mesh box 404 directly below the outlet of the inclined funnel 401.

[0024] Among them, one end of each of the two horizontal support plates 4031 is connected to the same positioning plate 4034. The bottom end of the horizontal support plate 4031 is provided with a reinforcing rib 4035 connected to the inner wall of the liquid storage chamber 402. The positioning plate 4034 can quickly position the slag receiving mesh box 404. The reinforcing rib 4035 improves the stability of the horizontal support plate 4031, thus providing stability to the slag receiving mesh box 404.

[0025] The machine tool body 1 is provided with a slag discharge port 7 located at the horizontal support plate 4031. A protective door 8 is connected to the slag discharge port 7 via a rotating shaft. The protective door 8 is locked to the machine tool body 1 by a latch. The protective door 8 is provided with a handle. By opening the latch, the protective door 8 can be opened through the handle, thereby discharging the slag receiving mesh box 404 from the slag discharge port 7 (the size of the slag receiving mesh box 404 is smaller than the size of the slag discharge port 7).

[0026] One side of the positioning plate 4034 is provided with a first magnet 9, and one end of the slag receiving mesh box 404 is provided with a second magnet 10 with a magnetic field different from that of the first magnet 9. The arrangement of the first magnet 9 and the second magnet 10 improves the stability of the slag receiving mesh box 404.

[0027] During operation, in this type of CNC wire EDM machine, during the wire cutting process, coolant and debris enter the inclined funnel 401 inside the storage chamber 402. Guided by the inclined funnel 401, the coolant and debris enter the slag collection box 404. The debris remains inside the slag collection box 404, while the coolant flows through the mesh of the slag collection box 404 into the storage chamber 402. This facilitates the filtration of debris mixed in with the coolant, preventing debris from entering the storage chamber 402 and causing blockages in the subsequent pipeline, thus ensuring normal circulation.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
