Description

Technical Field

[0001] The utility model relates to the field of machining cooling devices, in particular to a machining cooling device for duplex stainless steel. Background Art

[0002] Duplex stainless steel refers to stainless steel with ferrite and austenite accounting for about 50% each, and the content of the lesser phase generally needs to reach at least 30%. When duplex stainless steel products are cut with a turning tool, the smoothness of the product cannot meet the quality requirements if the machine tool speed is low. When the machine tool speed is high, the product overheats and discolors, and cutting fluid must be used for cooling and lubrication;

[0003] However, the cutting fluid on the market is generally collected through a collection box at the bottom of the machine tool and then transported by a water pump. However, after long-term use, due to the particularity of machining, more impurities such as iron filings will be generated, causing the filter plate to be blocked, affecting the transportation of cutting fluid;

[0004] Therefore, it is necessary to propose a machining cooling device for duplex stainless steel to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a machining cooling device for duplex stainless steel, so as to solve the problem that a filter plate of the cooling device is blocked after long-term use, thereby affecting the delivery of cutting fluid.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a duplex stainless steel machining cooling device, comprising a cooling box and a collecting box arranged on a machine tool, a water tank is fixedly arranged inside the cooling box, a sedimentation box for treating impurities is arranged inside the water tank, and a partition plate for dividing the internal space of the water tank is fixedly arranged inside the water tank;

[0007] An inclined plate is fixedly provided inside the sedimentation box, and a plurality of vertical holes are penetrated through one side of the inclined plate. A baffle is also fixedly provided inside the sedimentation box, and a return plate is fixedly provided on the upper end of the baffle, and the return plate is arranged in an arc shape.

[0008] Preferably, a first water pump and a second water pump are fixedly provided on the inner side of the cooling box, a liquid extraction pipe is fixedly provided on the input end of the second water pump, the liquid extraction pipe extends on the inner side of the water tank, a water spray head is fixedly provided on the upper end of the machine tool, and the output end of the second water pump is connected to the water spray head through a water pipe.

[0009] Preferably, the opening direction of the vertical hole and the output direction of the first water pump are arranged perpendicularly.

[0010] Preferably, a plurality of first liquid passage holes are provided at one end of the sedimentation box.

[0011] Preferably, the first water pump input end is connected to the inner side of the collecting box, and the first water pump output end is connected to the inner side of the sedimentation tank.

[0012] Preferably, a plurality of second liquid passage holes are formed through a side of the partition plate away from the sedimentation tank.

[0013] Technical effects and advantages of the utility model:

[0014] 1. Through the setting of the sedimentation box, the first water pump sucks the cutting fluid that has just been used into the sedimentation box, so that the cutting fluid with impurities such as iron chips contacts the inclined plate. Through the direction setting of the first water pump and the vertical hole, a water flow corner is generated at the vertical hole, so that the iron chips stay on the inclined plate, and the reflux plate is used to intercept the running iron chips. When the first water pump stops working, the iron chips are sunk by their own gravity and enter the bottom of the sedimentation box, and the baffle is used to intercept the precipitated iron chips;

[0015] 2. The water tank is separated into three separate chambers through the partition plate and the sedimentation tank, so that the cutting fluid can enter the second water pump after double filtration;

[0016] 3. The shape of the reflux plate is set to use the flowing cutting fluid to flush the back of the inclined plate, so that the cutting fluid drives the iron chips to move in a circular motion, and each time the iron chips move, the centrifugal force causes the iron chips to be on the outer side of the circle, so that the baffle intercepts a certain amount of iron chips.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides Figure 1 - Figure 4 A duplex stainless steel machining cooling device is shown, comprising a cooling box 1 and a collecting box 2, wherein the cooling box 1 and the collecting box are arranged on a machine tool, a first water pump 4 and a second water pump 6 are fixedly arranged inside the cooling box 1, and a control panel is arranged on the machine tool to control the first water pump 4 and the second water pump 6;

[0024] The cutting fluid is composed of water, talcum powder, alcohol, and liquid wax to form an oil-free cutting fluid, in which water accounts for 85%, talcum powder accounts for 5%, alcohol accounts for 4%, and liquid wax accounts for 6%. It is used to replace conventional oily cutting fluid and is used for machining of duplex stainless steel.

[0025] A liquid pumping pipe 601 is fixedly provided at the input end of the second water pump 6. The liquid pumping pipe 601 is a prior art and will not be described in detail here.

[0026] A water tank 3 is fixedly arranged inside the cooling box 1, and a liquid extraction pipe 601 extends inside the water tank 3. A sedimentation tank 7 for treating impurities is arranged inside the water tank 3. The input end of the first water pump 4 is connected to the inside of the collecting box 2, and the output end of the first water pump 4 is connected to the inside of the sedimentation tank 7. A partition plate 8 for dividing the internal space of the water tank 3 is fixedly arranged inside the water tank 3. The partition plate 8 is concavely arranged to fit the sedimentation tank 7.

[0027] An inclined plate 9 is fixedly provided on the inner side of the sedimentation box 7. A plurality of vertical holes 10 are penetrated through one side of the inclined plate 9. The first water pump 4 transports cutting fluid toward the inside of the sedimentation box 7. The opening direction of the vertical hole 10 is perpendicular to the output direction of the first water pump 4. A baffle plate 11 is also fixedly provided on the inner side of the sedimentation box 7. A return plate 12 is fixedly provided on the upper end of the baffle plate 11. The return plate 12 is arranged in an arc shape to wrap the inclined plate 9.

[0028] A water spray head 602 is fixedly provided at the upper end of the machine tool. The output end of the second water pump 6 is connected to the water spray head 602 through a water pipe. The water spray head 602 is controlled by a switch valve. The water spray head 602 is a prior art and will not be described in detail here.

[0029] A plurality of first liquid holes 701 are provided at one end of the sedimentation box 7 to facilitate the discharge of the cutting fluid inside the sedimentation box 7 .

[0030] A plurality of second liquid holes 801 are formed through one side of the partition plate 8 away from the sedimentation tank 7 to increase the path for the iron chips to follow the cutting fluid out of the partition plate 8 and reduce the iron chips from contacting the liquid extraction pipe 601 .

[0031] When the first water pump 4 and the second water pump 6 stop working, the cutting fluid inside the water tank 3 gradually becomes static, and the iron chips sink due to their own gravity and enter the bottom of the sedimentation tank. The baffle is used to intercept the thickly precipitated iron chips, and the flow force at the bottom of the water tank 3 is the smallest when the water pump is working, which can reduce the iron chips driven by the cutting fluid.

[0032] Working principle: The operator turns on the first water pump 4 and the second water pump 6 through the machine tool control panel, so that the second water pump 6 extracts the cutting fluid inside the water tank 3 through the liquid extraction pipe 601, and then transports it to the water spray head 602 through the pipeline to cool the duplex stainless steel machining;

[0033] At the same time, the cutting fluid discharged by the water spray head 602 enters the interior of the collecting box 2, and is then pumped by the first water pump 4 and enters the interior of the sedimentation box 7. The cutting fluid pumped in by the first water pump 4 contacts the inclined plate 9, and then the iron filings in the cutting fluid are intercepted for the first time through the setting of the vertical hole 10, and then the cutting fluid contacts the return plate 12. Through the shape setting of the return plate 12, the back of the inclined plate 9 is flushed with the flowing cutting fluid, so that the cutting fluid drives the iron filings to move in a circular motion, and each time the motion is carried out, the iron filings are located on the outer side of the circle through the centrifugal force, so that the baffle 11 intercepts a certain amount of iron filings, and the cutting fluid contacts the partition plate 8 through the first liquid hole 701, and then contacts the extraction pipe 601 from the second liquid hole 801, completing the recycling of the cutting fluid;

[0034] After the first water pump 4 and the second water pump 6 stop working, the cutting fluid gradually stops flowing, so that the iron filings in the cutting fluid settle to the bottom of the water tank 3 due to their own weight. In addition, the position setting of the first liquid hole 701 and the second liquid hole 801 can minimize the fluidity of the cutting fluid at the bottom of the water tank 3 and reduce the flow of iron filings to avoid blockage.
