Description

Technical Field

[0001] This utility model belongs to the technical field of wire cutting equipment, and in particular relates to a medium-speed wire cutting device that can perform dust removal. Background Technology

[0002] Wire EDM equipment can be divided into three main categories according to the wire feed speed: fast wire EDM equipment, medium wire EDM equipment, and slow wire EDM equipment. Medium wire EDM equipment is a type of EDM machine tool that achieves a processing quality between fast wire EDM and slow wire EDM by combining a composite wire feed method with multiple cutting technology.

[0003] Chinese patent application CN207723640U discloses a medium-speed wire EDM machine capable of dust removal, comprising a base plate, a base box fixedly connected to the top right side of the base plate, a wire EDM body fixedly connected to the top left side of the base box, a dust removal plate on the top of the base box, a dust removal pipe fixedly connected to the bottom of the dust removal plate penetrating the base box and extending into the interior of the base box, and a dust removal hole on the top of the dust removal plate. An exhaust fan is fixedly connected to the left side of the base box. This invention solves the problem of existing medium-speed wire EDM machines being unable to perform dust removal by using a dust removal plate, dust removal pipe, dust removal hole, exhaust fan, water tank, pipe, motor, rotating rod, first bearing, stirring rod, water outlet, and air outlet in a coordinated manner. This dust-removing medium-speed wire EDM machine has the advantage of dust removal, protects the user's health, and thus improves the practicality of medium-speed wire EDM machines.

[0004] The aforementioned type of medium-speed wire EDM machine capable of dust removal is equipped with an exhaust fan, a dust collection pipe, and a water tank. The exhaust fan provides negative pressure to the dust collection pipe, drawing dust from the machine body into the water tank for dissolution. However, since this dust mainly consists of metal dust and a small amount of other dust, directly introducing it into the water tank, while removing the dust, also rapidly contaminates the water, forming sediment or suspended matter. Therefore, frequent water changes are necessary to ensure the water tank can continue to purify the dust. This leads to water waste; furthermore, the bottom of the machine's casing is equipped with a dust collection plate, on which a dust collection pipe is embedded. The dust collection pipe connects to the internal environment of the casing through a dust collection hole. However, the metal dust in the wire EDM equipment is quite hot. Directly drawing this hot dust into the dust collection pipe by the exhaust fan not only damages the pipe but also causes some of the dust to adhere to the inner wall of the dust collection hole as it enters, leading to blockage. Therefore, we provide a wire EDM device capable of dust removal to solve the aforementioned problems. Utility Model Content

Finally, the atomizing nozzle sprays the misted water around the negative pressure head, thereby cooling the metal dust generated during the cutting process. Attached Figure Description

The slide 404a is fixedly installed on the upper middle outer wall of the hollow plate 404. The power component 201 and the wire cutting assembly 202 are both conventional equipment of medium-speed wire cutting equipment, i.e., existing technology. Example

[0027] Please see Figure 4 Based on Example 1, a water tank 3, a dust collection component 4, and a cooling component 5 are also provided. The cooling component 5 can spray mist water to cool down the metal dust generated during the cutting process. The dust collection component 4 absorbs the cooled metal dust and inputs it into the water tank 3.

[0028] Specifically, a mounting groove 102 is provided on the rear side wall of the upper end of the machine base 1. The mounting groove 102 is used for the installation of the water tank 3. The water tank 3 is also connected to the dust collection component 4 and the cooling component 5. The dust collection component 4 includes a negative pressure head 401, which is installed on the outer wall of the mounting block 402. The upper side wall of the mounting block 402 is connected to the hollow plate 404 through an electric push rod 403. The negative pressure head 401 is also connected to the hollow plate 404 through a negative pressure pipe 401b. The hollow plate 404 is also connected to the exhaust fan 406 through a first hose 405. The cooling component 5 includes an atomizing nozzle 501, which is connected to a water pipe 503 through a second hose 502. The water pipe 503 is also connected to a water pump 504, which is installed inside the water tank 3.

[0029] Furthermore, the exhaust fan 406 is connected to the water tank 3 via the exhaust pipe 406a. The water tank 3 is equipped with a water storage tank 303, and a purification plate 301 is installed inside the water storage tank 303. The upper end of the water tank 3 is covered with a tank cover 304. A pipe sleeve 305 for connecting to the exhaust pipe 406a is embedded in the purification plate 301. A metal mesh 401a is embedded on the negative pressure head 401, and the negative pressure head 401 is connected to the mounting block 4 via a pipe clamp 401c. 02 connection, one end of the hollow plate 404 is connected to the hose 405 through the bent plate 405a, the exhaust fan 406 is equipped with an exhaust pipe 406a, and the end of the exhaust pipe 406a is located below the purification plate 301. The atomizing nozzle 501 is connected to the side wall of the mounting block 402 through the pipe clamp 501a. The water pump 504 is connected to the inner wall of the water tank 3 above the purification plate 301 through the mounting bracket 504a.

[0030] The operation process of this embodiment is as follows: When in use, hold the slide 404a at the upper end of the hollow plate 404 and push it into the slide groove 101 until the negative pressure head 401 is aligned with the cutting position of the wire in the material. The cooperation of the first hose 405 and the second hose 502 ensures the completeness of the position adjustment. Then, start the electric push rod 403 to adjust the height. The water pump 504 works, which draws water from the purification plate 301 in the water tank 3 into the water pipe 503 and sprays it around the negative pressure head 401 through the atomizing nozzle 501. The exhaust fan 406 in the dust collection assembly 4 works, and the negative pressure it generates is transmitted through the first hose 405, Hollow plate 404 and negative pressure pipe 401b transmit the pressure to negative pressure head 401. Negative pressure head 401 absorbs metal dust and mist water in the surrounding environment through metal mesh 401a. During absorption, the metal dust comes into contact with the mist water, thereby achieving the effect of rapidly reducing the temperature of the metal dust. At this time, the cooled metal dust passes through the metal mesh and enters the negative pressure head 401, and enters the interior of water tank 3 through negative pressure pipe 401b, hollow plate 404, hose 405, exhaust fan 406 and air outlet pipe 406a. After contacting the water, the metal dust dissolves into the water in water tank 3, while the gas rises in the water and is discharged through air outlet pipe 302. Example

[0031] Please see Figure 5 Based on Embodiments 1 and 2, a purification plate 301 is also provided. By using the purification plate 301, metal dust can be left at the bottom of the water tank 3, while the clean water on the upper layer of the purification plate 301 can be reused for the cooling component 5.

[0032] Specifically, the purification plate 301 is horizontally positioned in the middle of the water storage tank 303, and the purification plate 301 contains a fruit shell filter plate 301a, a quartz sand filter plate 301b, and a sponge filter plate 301c.

[0033] Furthermore, a fruit shell filter plate 301a and a sponge filter plate 301c are respectively provided on the upper and lower sides of the quartz sand filter plate 301b, and the air outlet pipe 302 is provided on the box cover 304, with its end located above the purification plate 301.

[0034] The operation process of this embodiment is as follows: When in use, the gas containing metal dust drawn into the water tank 3 will enter the lower part of the purification plate 301 and come into contact with the water. Then, the gas will rise in the water and come into contact with the sponge filter plate 301c, the quartz sand filter plate 301b and the nut shell filter plate 301a in sequence. Then, it will pass through the nut shell filter plate 301a and enter the upper part of the purification plate 301, and finally flow out through the air outlet pipe 302.
