Description

Technical Field

[0001] This utility model relates to the field of multi-wire cutting machine technology, specifically to a filtration and cooling device for the backflow cutting fluid in a multi-wire cutting machine. Background Technology

[0002] A multi-wire cutting machine is a device used for cutting hard materials. Its working principle is to use the high-speed reciprocating motion of metal wires to bring abrasive into the processing area of ​​the material to be cut for grinding, and to cut the material into hundreds or thousands of thin slices at the same time.

[0003] Besides the combination of metal wire and abrasive, multi-wire cutting machines can also use a combination of diamond wire and cutting fluid. In a multi-wire cutting machine using this combination, the diamond wire moves at high speed to cut the material, while the cutting fluid acts as a coolant, carrying away the heat and debris generated during cutting and flowing back to the cutting fluid supply system. To achieve fluid recycling, the debris and impurities in the returned cutting fluid must be removed.

[0004] In the existing technology, the backflow of cutting fluid from multi-wire cutting machines cannot be effectively treated, resulting in a large number of impurities in the cutting fluid, which does not meet the requirements for the recycling of cutting fluid, thus affecting the quality of multi-wire cutting products. Utility Model Content

[0005] This utility model provides a device for treating reflux cutting fluid in a multi-wire cutting machine. It aims to achieve the deposition and filtration of debris and impurities in the reflux cutting fluid through the cooperation of a recovery unit, a filter plate, and a cooling unit, and to cool the filtered cutting fluid, so as to meet the requirements for the recycling of cutting fluid and improve the quality of multi-wire cutting products.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multi-wire cutting machine reflux cutting fluid treatment device is an overall box structure. A partition is provided in the inner cavity of the box to divide the box into a recovery section and a cooling section. A cutting fluid outflow port is provided on the partition to connect the recovery section and the cooling section. A filter plate is installed at the cutting fluid outflow port.

[0008] The top of the recovery section is provided with a first cover plate, and a filter cylinder is installed on the first cover plate. The upper end of the filter cylinder is connected to the cutting fluid return pipeline, and the bottom extends downward to the recovery section of the box. The recovery section is also provided with a sedimentation tank.

[0009] The top of the cooling section is provided with a second cover plate, on which a cutting fluid pump and a stirring assembly are installed. The stirring assembly includes a stirring motor and a stirring shaft. The inlet of the cutting fluid pump and the stirring shaft of the stirring assembly extend into the cooling section of the housing. The cooling section of the housing is also provided with cooling pipes. The inlet and outlet of the cooling pipes are respectively connected to a separately provided cooling medium supply system.

[0010] In the aforementioned multi-wire cutting machine reflux fluid treatment device, the filter cylinder in the recovery section has a double-layer sleeve structure. The outer cylinder is fixed to the first cover plate, and the inner cylinder wall and bottom are equipped with filter screens. The sedimentation tank includes an overflow tank and a guide tank. The overflow tank is located in the middle of the inner cavity of the recovery section. The inner cylinder of the filter cylinder extends into the overflow tank. The overflow tank has a rectangular structure, with one side wall height lower than the other three side walls, forming an overflow port. The guide tank surrounds the overflow tank in a semi-enclosed form. The overflow port of the overflow tank is connected to one end of the guide tank, which is also the inlet of the guide tank. The other end of the guide tank is the outlet of the guide tank. A set of baffles is set in the guide tank. The height of the baffles decreases from the inlet to the outlet of the guide tank. The outlet height of the guide tank is lower than the height of the filter plate at the fluid flow port.

[0011] The above-mentioned multi-wire cutting machine reflux cutting fluid treatment device has a door-shaped frame structure around the cutting fluid inlet on the partition plate, and slots are set on the vertical frames on both sides. There are two sets of filter plates, and the two sides of each set of filter plates are inserted into the corresponding slots from top to bottom. A filter plate handle is provided on the top of the filter plate.

[0012] The above-mentioned multi-wire cutting machine reflux cutting fluid treatment device also includes a liquid level monitor in the inner cavity of the recovery section; the liquid level monitor is arranged on the outside of the sedimentation tank.

[0013] The above-mentioned multi-wire cutting machine reflux cutting fluid treatment device has a support foot at the bottom of the sedimentation tank and a sedimentation tank handle on the side wall of the sedimentation tank.

[0014] The aforementioned multi-wire cutting machine reflux cutting fluid treatment device has a double-layer structure in the housing, forming a sealed cavity between the inner and outer walls of the housing.

Its working principle is as follows: the refluxed cutting fluid from the multi-wire cutting machine is collected in the recovery section, and large particles of debris and impurities are removed by the filter cartridge in the recovery section. Then, it passes through a sedimentation tank where larger particles of debris and impurities are further deposited at the bottom. Next, under the suction of the cutting fluid pump in the cooling section, the cutting fluid in the recovery section flows to the cooling section through the cutting fluid outlet of the partition. At the cutting fluid outlet, smaller particles of debris and impurities in the cutting fluid are removed by the filter plate. This three-stage filtration and sedimentation process meets the requirements for the recycling of the cutting fluid. This invention features two sets of filter plates, which are inserted into the cutting fluid outlet of the partition. One set of filter plates can be removed for cleaning without stopping the multi-wire cutting machine, thus saving filter plate maintenance time and improving production efficiency. This invention allows monitoring of the flow of cutting fluid and the deposition of debris and impurities in the tank through observation windows on the first cover plate of the recovery section and the second cover plate of the cooling section. Cutting fluid that is no longer suitable for recycling can be replaced through the drain port as needed. In summary, this utility model achieves the goals of meeting the requirements for the recycling of cutting fluid and improving the quality of multi-wire cutting products through the above technical means.

[0047] See also Figure 1 , Figure 2 , Figure 3The multi-wire cutting machine reflux cutting fluid treatment device of this utility model has a second cover plate 3 on the top of its cooling section II. A cutting fluid pump 6 and a stirring assembly 7 are installed on the second cover plate 3. The stirring assembly 7 includes a stirring motor and a stirring shaft.

[0050] See Figures 1 to 10 This utility model provides a device for treating reflux cutting fluid from a multi-wire cutting machine. Its working principle is as follows: the refluxed cutting fluid from the multi-wire cutting machine is collected in the recovery section I, and large particles of debris and impurities are removed by the filter cartridge 5 in the recovery section I. Then, it passes through a sedimentation tank 11, where larger particles of debris and impurities are further deposited at the bottom. Then, under the suction of the cutting fluid pump 6 in the cooling section, the cutting fluid in the recovery section I flows through the cutting fluid outlet of the partition 1-1 to the cooling section II. At the cutting fluid outlet, smaller debris and impurities in the cutting fluid are removed by the filter plate 4. This three-stage filtration and sedimentation process satisfies the requirements for the recycling of cutting fluid. (See attached diagram) Figure 10As shown, during the sedimentation tank 11 of the recovery section I of this utility model, the returned cutting fluid is filtered by the inner cylinder of the filter cylinder 5 and flows into the overflow tank 11-1 of the sedimentation tank 11. Then, it enters the guide tank 11-2 through the overflow port 11-3. Under the blocking effect of the baffle 11-5 with decreasing height inside the guide tank 11-2, the debris and impurities in the cutting fluid gradually settle at the bottom of the guide tank 11-2. The relatively clean cutting fluid at the top of the guide tank 11-2 flows from the outlet 11-4 of the guide tank to the cutting fluid outlet of the baffle 1-1. This invention features two sets of filter plates 4 at the cutting fluid inlet of the partition 1-1. These plates are inserted into slots 1-2 on the vertical sides of the cutting fluid inlet of the partition 1-1. A filter plate handle 4-1 is provided above the filter plates 4, exposed above the housing 1. Therefore, without stopping the multi-wire cutting machine, one set of filter plates 4 can be pulled out for cleaning via the handle 4-1, while the other set of filter plates 4 filters the cutting fluid. This saves filter plate maintenance time and improves production efficiency. This invention allows monitoring of the flow of cutting fluid and the deposition of debris and impurities in the housing 1 through observation windows on the first cover plate 2 of the recovery section I and the second cover plate 3 of the cooling section II. Cutting fluid that is no longer suitable for recycling can be replaced in a timely manner through the drain port 1-3. In this invention, the sedimentation tank 11 in the recovery section I is placed in the housing via bottom supports 11-6, and a sedimentation tank handle 11-7 is provided on the side wall of the sedimentation tank. After the multi-wire cutting machine has been working for a certain period of time, or when abnormal flow of the cutting fluid in the housing is observed, the first cover plate 2 above the recovery section I can be opened, and the sedimentation tank 11 can be removed from the housing 1 using lifting tools, and then the sedimentation tank 11 can be cleaned. This invention allows the housing 1 to be moved by pushing and pulling the handles 1-5 of the housing 1 to adapt to the overall layout of the multi-wire cutting machine.
