Description

Technical Field

[0001] This utility model relates to the technical field of wire electrical discharge machining, and in particular to a fast wire EDM CNC wire cutting machine. Background Technology

[0002] Fast wire EDM, also known as high-speed wire EDM, uses a continuous metal wire (such as tungsten wire) as an electrode. Through high-speed reciprocating motion, it generates an electric spark discharge with the workpiece. When the distance between the workpiece and the electrode wire is less than the discharge distance, a high-frequency pulse power supply is applied, causing the working fluid to ionize and break down, forming a discharge channel. Under the influence of the electric field, negatively charged electrons and positively charged ions move at high speed, generating high temperatures that melt or even vaporize the workpiece surface. The metal is ejected as the electrode wire moves and is impacted by the working fluid, creating pits on the workpiece surface. During the machining process, the electrode wire reciprocates at high speed, continuously generating electric spark discharges with the workpiece, gradually eroding the workpiece material through the discharge energy. A stepper motor controls the gap between the electrode wire and the workpiece, maintaining a necessary discharge gap, thus gradually cutting a slit in the workpiece. Therefore, a fast wire EDM CNC machine is needed.

[0003] Existing fast wire EDM CNC machines generate high temperatures and sparks during the wire cutting process, releasing metal vapors and other harmful gases, such as aluminum oxide and zinc oxide. Prolonged inhalation of these substances may lead to respiratory problems, such as asthma and chronic bronchitis. Utility Model Content

In the wire cutting process, the existing fast wire EDM CNC machine tool generates high temperature and sparks, and releases metal vapor and other harmful gases, such as aluminum oxide and zinc oxide. Long-term inhalation of these substances may lead to respiratory problems, such as asthma and chronic bronchitis.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fast wire EDM CNC wire cutting machine tool, comprising a machine tool, a first shaft plate fixedly connected to the upper surface of the machine tool, a second shaft plate connected to the surface of the first shaft plate, a worktable fixedly connected to the upper surface of the second shaft plate, a through hole opened on the surface of the worktable, a lifting platform fixedly installed on one side of the upper surface of the machine tool, a support plate connected to one side of the lifting platform, and a smoke removal mechanism provided at one end of the support plate;

Fixed plates are fixedly installed on both sides of the support plate, and clamping plates are fixedly installed on the surface of the fixed plates. A concave tube passes through one end of the clamping plate, and tapered openings are provided at both ends of the concave tube. A flexible tube is fixedly connected to one side of the concave tube, and a connecting pipe is connected to one end of the flexible tube.

[0008] Preferably, a base is welded to one side of the machine tool, and a blower is fixedly installed on one side of the surface of the base, and a coolant tank is fixedly placed on the upper side of the base.

[0009] Preferably, a return water pipe is fixedly connected to one side of the surface of the workbench, and one end of the return water pipe is connected through the coolant tank.

[0010] Preferably, a water outlet pipe is connected through one side of the coolant tank, a water pump is connected to one end of the water outlet pipe via a flange, and a connecting pipe is connected to one side of the water pump via a flange.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This fast wire EDM CNC wire cutting machine tool, through the setting of the smoke removal mechanism, has tapered openings at both ends of the concave tube located on both sides of the cutting work during use. During cutting, the suction force generated by the blower can adsorb the smoke generated during the cutting process through the tapered openings into the concave tube at the same time as the smoke is generated. Then, it is sent into the coolant tank through the flexible tube and the blower. The water-based coolant in the coolant tank can perform preliminary adsorption on the smoke. Then, the gas is further adsorbed by the adsorption packing. Finally, the purified smoke is discharged through the outlet. Attached Figure Description

Then, the fumes are sent into the coolant tank 10 through the concave pipe 803, flexible pipe 805, connecting pipe 806 and blower 807.

[0023] Furthermore, a support rod 808 is fixedly installed on one side of the upper surface of the second shaft plate 3. One end of the support rod 808 is fixedly connected to a collar 809, and the collar 809 is sleeved on the outer ring of the flexible tube 805. Through the setting of the support rod 808, the support rod 808 and the collar 809 can support the flexible tube 805. At the same time, when the support plate 7 is raised and lowered, it can pull the flexible tube 805, and the support rod 808 can also move on the second shaft plate 3. The range of movement of the first shaft plate 2 and the second shaft plate 3 fully meets the requirements of the support rod 808 and will not affect the use of the flexible tube 805.

[0024] Furthermore, a base 9 is welded to one side of the machine tool 1, and a blower 807 is fixedly installed on one side of the surface of the base 9. A coolant tank 10 is fixedly placed on the upper side of the base 9. Through the arrangement of the coolant tank 10, water-based coolant is stored in the coolant tank 10 at a position higher than the outlet pipe 12 and lower than the return pipe 11.

[0025] Furthermore, a return water pipe 11 is fixedly connected to one side of the surface of the workbench 4. One end of the return water pipe 11 is connected to the coolant tank 10.

[0029] Working principle: First, the workpiece to be processed is fixed on the fixed fixture above the worktable 4. Then, the workpiece is processed. At the same time, the coolant in the coolant tank 10 is delivered to the connecting pipe 14 by the water pump 13. Then, the cutting position is cooled and sprayed by the nozzle at one end of the connecting pipe 14. At the same time, when the cutting generates fumes, the blower 807 drives the conical nozzle 804 to generate suction. The fumes are absorbed on both sides of the cutting position. Then, they are sent into the coolant tank 10 through the concave pipe 803, flexible pipe 805, connecting pipe 806 and blower 807. The fumes enter the coolant tank 10 and are initially filtered by the coolant. Then, the fumes rise to the partition 15 and are further adsorbed and purified by the adsorption packing 16. Finally, they are discharged through the outlet 17.
