Description

Technical Field

[0001] The utility model relates to the technical field of wire cutting machines, in particular to a cooling liquid filtering device for wire cutting machines. Background Art

[0002] Wire EDM is referred to as "wire cutting". Its main working principle is that under the action of pulse power supply, spark discharge will be formed between the tool electrode and the workpiece, so that the workpiece is melted and the surface of the workpiece is processed. In order to cool the workpiece, coolant needs to be sprayed on the surface of the workpiece.

[0003] The coolant of existing cutting machine tools usually passes through a circulation system, is filtered and cooled, and then reused. However, when the filter used to filter impurities needs to be replaced and cleaned, the machine needs to be shut down for processing, which reduces work efficiency and is not suitable for industrial applications.

[0030] The second filter chamber 40 is connected to the second liquid outlet and is used to receive the coolant output from the second liquid outlet. The second filter chamber 40 is provided with a second filter 401 for filtering impurities.

[0031] The cooling chamber 50 is connected to the first filter chamber 30 and the second filter chamber 40 and is used to receive the coolant filtered from the first filter chamber 30 and the second filter chamber 40;

[0032] The pumping assembly 60 includes a first pumping unit connected to the working chamber 10 and the guide chamber 20 for pumping the coolant in the working chamber 10 to the guide chamber 20, and a second pumping unit connected to the cooling chamber 50 and the working chamber 10 for pumping the coolant in the cooling chamber 50 to the working chamber 10.

[0033] Specifically, in this embodiment, the coolant is transported to the guide chamber 20 through the first pumping unit. When the closing plate 201 is driven by the driving component and is located on the first liquid outlet, the first liquid outlet is closed, and the coolant enters the second filter chamber 40 through the second liquid outlet, and enters the cooling chamber 50 after being filtered by the second filter 401, and flows back to the working chamber 10 through the second pumping unit; when the closing plate 201 is driven by the driving component and is located on the second liquid outlet, the second liquid outlet is closed, and the coolant enters the first filter chamber 30 through the first liquid outlet, and enters the cooling chamber 50 after being filtered by the first filter 301, and flows back to the working chamber 10 through the second pumping unit; through the above arrangement, the recycling of the coolant is effectively realized. At the same time, when the first filter 301 / the second filter 401 needs to be replaced, it is only necessary to close the corresponding first liquid outlet / the second liquid outlet through the closing plate 201 as needed, without stopping work, which greatly improves work efficiency and is suitable for industrial applications.

[0034] Specifically, the drive assembly includes a third motor 202 and a screw rod 203; the screw rod 203 is installed in the connecting port, and the third motor 202 is installed on the side of the connecting port, and is used to drive the screw rod 203 to rotate, so that the screw rod drives the closing plate 201 to switch between closing the first filter chamber 30 and closing the second filter chamber 40.
