Description

Technical Field

[0001] The present application relates to the field of chip removal equipment, and in particular to a chip removal device used in machine tools with high chip removal capacity. Background Art

[0002] Machine tool processing is a common processing method in the manufacturing industry. When the machine tool processes the workpiece, in order to reduce the temperature rise of the cutting head, a cutting fluid is usually used to cool the head. The cutting fluid is mixed with the waste chips cut off from the workpiece, so that the used cutting fluid cannot be directly reused. The amount of cutting fluid used is large, especially for machine tools with high chip discharge volume. The consumption of cutting fluid is even greater. For this reason, people began to discharge the waste chips in the cutting fluid so that the cutting fluid can be recycled and reused.

[0003] The traditional way to treat the cutting fluid is to let the cutting fluid pass through a layer of filter screen, and then filter out the waste chips in the cutting fluid through the filter screen to achieve the purpose of chip removal. However, for machine tools with high chip removal capacity, waste chips of different sizes in the cutting fluid will form a waste chip layer of a certain thickness on the filter screen in a short period of time, resulting in a decrease in the flow rate of the cutting fluid, thereby reducing the chip removal efficiency of the cutting fluid. At the same time, manual cleaning of the waste chips on the filter screen is required in a timely manner, further increasing the labor intensity of the workers. Summary of the Invention

[0004] In order to improve the problem that waste chips of different sizes in the cutting fluid will form a waste chip layer of a certain thickness on the filter net in a short time, thereby reducing the chip removal efficiency of the cutting fluid, the present application provides a chip removal device for use in machine tools with high chip removal capacity.

[0005] The present application provides a chip removal device for a high chip removal machine tool using the following technical solution:

[0006] A chip removal device for a machine tool with a high chip removal capacity comprises a conveying channel, a first cleaning trough, a second cleaning trough, a first chip removal unit, a second chip removal unit and a third chip removal unit. The conveying channel is used to collect a mixture of cutting fluid and waste chips discharged from the machine tool. The conveying channel is connected to the first cleaning trough. The first chip removal unit is used to discharge the upper floating chips in the cutting fluid flowing into the first cleaning trough. The second cleaning trough is used to receive the cutting fluid flowing out of the first cleaning trough. The second chip removal unit is used to discharge the suspended chips in the cutting fluid flowing into the second cleaning trough. The third chip removal unit is used to discharge the bottom precipitated chips in the cutting fluid flowing into the second cleaning trough.

[0007] By adopting the above technical solution, when processing the cutting fluid discharged from the machine tool, the cutting fluid generated by each machine tool is first collected through the conveying channel and passed into the first cleaning tank, and then the upper floating chips in the cutting fluid in the first cleaning tank are discharged through the first chip removal unit, and then the treated cutting fluid flows into the second cleaning tank, and the middle suspended chips in the second cleaning tank are discharged through the second chip removal unit, and the bottom precipitated chips in the second cleaning tank are discharged by the third chip removal unit, thereby realizing the chip removal of waste chips in the cutting fluid. By performing chip removal three times according to the characteristics of different waste chips, the chip removal efficiency of machine tools with high chip removal capacity is improved.

[0008] In a specific feasible implementation scheme, the first chip removal unit includes a material box and a first conveyor belt. The material box is arranged in the first cleaning trough, the conveying channel is connected to the material box, the first conveyor belt is slidably arranged in the material box, the material box is provided with a discharge port, the first conveyor belt is provided with a plurality of screening holes for screening out the upper floating chips, and the first conveyor belt extends from the conveying channel to the discharge port.

[0009] By adopting the above technical solution, when the cutting liquid flows into the material transport box from the conveying channel, the cutting liquid falls onto the first conveyor belt. The cutting liquid is screened by the screening holes, so that the upper floating chips remain on the first conveyor belt. Then the first conveyor belt transports the upper floating chips to the discharge port for discharge, thereby cleaning the upper floating chips and effectively avoiding excessive accumulation of waste chips on the first conveyor belt.

[0010] In a specific possible implementation scheme, the second chip removal unit includes a pumping unit, a storage box and a chip filter layer. The pumping unit is arranged in the second cleaning tank. A plurality of water pipes are provided at the outlet of the pumping unit. The chip filter layer is arranged at the liquid inlet of the storage box. Part of the water pipe extends away from one end of the pumping unit to the liquid inlet of the storage box and toward the chip filter layer. The chip filter layer is used to screen out the intermediate suspended chips in the cutting liquid.

[0011] By adopting the above technical solution, the cutting liquid in the second cleaning tank is pumped into the storage box through the water pipe by the pumping unit. When the cutting liquid enters the storage box, the intermediate suspended chips in the pumped cutting liquid are filtered out through the filter layer, thereby realizing the chip removal of waste chips in the cutting liquid, so that the cutting liquid in the storage box can be reused.

[0012] In a specific possible implementation manner, another portion of the water conduit extends into the delivery channel at an end away from the pumping unit and is communicated with the inner cavity of the delivery channel.

[0013] By adopting the above technical solution, the pumping unit pumps the cutting liquid in the second cleaning tank into the conveying channel through a part of the water pipe to flush the conveying channel, thereby flushing away the waste chips deposited in the conveying channel.

[0014] In a specific possible implementation scheme, the material transport box is provided with a drain port and a filter screen, and the filter screen covers the drain port.

[0015] By adopting the above technical solution, the processed cutting liquid in the material transport box flows into the second cleaning tank from the discharge port, and the filter net can effectively prevent the waste chips on the first conveyor belt from flowing into the second cleaning tank.

[0016] In a specific possible implementation scheme, the third chip removal unit includes a conveying box and a chip cleaning piece. The conveying box is arranged on the bottom wall of the second cleaning trough. The conveying box is used to collect the bottom sediment chips in the cutting liquid. The chip cleaning piece is arranged in the conveying box. The conveying box is provided with a drop port. The chip cleaning piece is used to transport the bottom sediment chips in the conveying box to the drop port.

[0017] By adopting the above technical solution, when the cutting fluid in the second cleaning tank is processed, the bottom sediment chips are settled in the transport box under the action of gravity, and then the waste chips settled in the transport box are cleaned by the chip cleaning part, thereby realizing the chip removal of the bottom sediment chips in the cutting fluid.

[0018] In a specific embodiment, the bottom wall of the first cleaning trough is provided with a first guide surface for guiding waste chips to move toward the conveying box, and the bottom wall of the second cleaning trough is provided with a second guide surface for guiding bottom sediment chips to move toward the conveying box.

[0019] By adopting the above technical solution, when waste chips are settling, the waste chips in the cutting liquid flowing out of the first cleaning trough are deposited along the first guide surface toward the conveying box, and the waste chips in the second cleaning trough are deposited along the second guide surface toward the conveying box, thereby effectively avoiding the accumulation of waste chips in the first cleaning trough and the second cleaning trough, and reducing the difficulty of manual cleaning of waste chips.

[0020] In a specific possible implementation scheme, the chip cleaning part includes a second conveyor belt and a push bar. The second conveyor belt is slidably arranged in the conveying box, the second conveyor belt extends to the drop port, and the push bar is arranged on the second conveyor belt along the width direction of the second conveyor belt.

[0021] By adopting the above technical solution, when the bottom-layer sediment chips settle into the conveying box, the bottom-layer sediment chips will be transferred to the second conveyor belt. The second conveyor belt will transfer the bottom-layer sediment chips to the drop port through the push bar and discharge them, thereby realizing the chip discharge of the bottom-layer sediment chips and effectively avoiding excessive accumulation of the bottom-layer sediment chips in the conveying box.

[0022] In a specific possible implementation scheme, the chip cleaning part includes a third conveyor belt and a collection net. The third conveyor belt is slidably arranged in the conveying box, and the third conveyor belt extends to the drop-out port. The collection net is rotatably arranged on the third conveyor belt. The third conveyor belt is provided with an elastic part for maintaining the collection net open. The collection net is opened to collect intermediate suspended chips. The conveying box is provided with a cleaning part at the drop-out port for cleaning the waste chips attached to the collection net and the third conveyor belt.

[0023] By adopting the above technical solution, when cleaning the settled waste chips, the third conveyor belt transports the waste chips settled in the transport box to the drop port and discharges them. During the movement of the conveyor belt, the collection net collects some of the intermediate suspended chips suspended in the cutting liquid, reducing the content of intermediate suspended chips in the cutting liquid and reducing the accumulation speed of waste chips on the filter layer. At the same time, the third conveyor belt and the collection net returned to the second cleaning tank are cleaned by the cleaning part, reducing the waste chips from entering the second cleaning tank again, and improving the chip removal efficiency of the third conveyor belt and the waste chips in the cutting liquid.

[0024] In a specific possible implementation scheme, the cleaning part includes a cleaning box, a cleaning cylinder, and an impact rod. The cleaning box is arranged on the conveying box, and the opposite side walls of the cleaning box are provided with passages for the third conveyor belt and the collecting net to pass through. The cleaning box is provided with an extrusion surface for pushing the collecting net to rotate toward the third conveyor belt, and the impact rod is arranged in the cleaning box. The collecting net is separated from the extrusion surface so that the collecting net hits the impact rod. The cleaning cylinder is rotatably arranged on the cleaning box, and the cleaning box is provided with a brush for cleaning the third conveyor belt and the collecting net. The cleaning box is provided with a telescopic spring for pulling the brush to fit the third conveyor belt or the collecting net.

[0025] By adopting the above technical solution, when the third conveyor belt and the cleaning net are cleaned, the third conveyor belt drives the cleaning net through the through port into the cleaning box, and the extrusion surface squeezes the collection net. At this time, the collection net is flipped and tilted. At this time, the elastic part contracts. When the collection net passes the extrusion surface and enters the cleaning box, the collection net hits the impact rod under the push of the elastic part. The vibration generated by the impact will vibrate off the waste debris attached to the cleaning net, and then the cleaning cylinder is driven to rotate. The cleaning cylinder contacts the conveyor belt under the pull of the telescopic spring, so that the brush can sweep off the waste debris attached to the third conveyor belt. As the third conveyor belt continues to move, the cleaning cylinder slides onto the cleaning net. At this time, the telescopic spring stretches, causing the cleaning cylinder to drive the brush to rotate on the cleaning net, thereby realizing the cleaning of the third conveyor belt and the waste debris on the cleaning net.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. When processing the chip liquid discharged from the machine tool, the chip liquid generated by each machine tool is first collected through the conveying channel and passed into the first cleaning tank. Then, the upper floating chips in the chip liquid in the first cleaning tank are discharged through the first chip discharge unit. Then, the treated chip liquid flows into the second cleaning tank. The middle suspended chips in the second cleaning tank are discharged through the second chip discharge unit. The third chip discharge unit discharges the bottom precipitated chips in the second cleaning tank, thereby realizing the chip removal of waste chips in the chip liquid. By performing chip removal three times according to the characteristics of different waste chips, the thickness of the waste chip layer during each chip removal can be reduced, thereby improving the chip removal efficiency of machine tools with high chip removal capacity.

[0028] 2. The upper floating liquid in the cutting liquid can be filtered and discharged through the first conveyor belt, and the bottom sediment in the cutting liquid can be discharged through the second conveyor belt. Only a small part of the intermediate suspension is filtered and discharged through the filter layer. The operator only needs to regularly clean the filter layer, thereby reducing the labor intensity;

[0029] 3. After the cleaning of the storage box, the chip liquid is returned to the machine tool for use again. At the same time, the pumping unit transports part of the chip liquid in the second cleaning tank to the conveying channel through the pipeline to flush the waste chips on the conveying channel. This can protect the chip liquid, speed up the flow of the chip liquid, and effectively avoid the chip liquid from stinking. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The following is combined with Figure 1-13 This application is described in further detail.

[0045] An embodiment of the present application discloses a chip removal device for use in a machine tool with a high chip removal capacity.

[0046] Example 1

[0047] Reference Figure 1 、 Figure 2 and Figure 4 A chip removal device for a high chip removal machine tool includes a conveying channel 11, a first cleaning trough 12, a second cleaning trough 13, a first chip removal unit 2, a second chip removal unit 3 and a third chip removal unit 4. In this embodiment, there are two conveying channels 11. The first cleaning trough 12 and the second cleaning trough 13 are both arranged on the foundation base 1. The first cleaning trough 12 is connected to the second cleaning trough 13. The depth of the second cleaning trough 13 is greater than the depth of the first cleaning trough 12. The waste chips in the cutting liquid in this embodiment mainly include upper floating chips, intermediate suspension and bottom sedimentation chips. When the surface tension resistance of the cutting liquid to the waste chips is greater than the gravity of the waste chips, the waste chips will float on the liquid surface of the cutting liquid to form upper floating chips. These upper floating chips Most of them are large in area and the largest in number, accounting for about 80% of the total amount of chips. When the resistance of the cutting liquid to the surface tension of the waste chips is approximately equal to the gravity of the waste chips, the waste chips are suspended in the cutting liquid to form intermediate suspended chips. The intermediate suspension accounts for about 10% of the total amount of chips. When the resistance of the cutting liquid to the surface tension of the waste chips is less than the gravity of the waste chips, these waste chips settle downward under the action of their own gravity to form bottom sediment chips. The bottom sediment chips account for about 10% of the total amount of chips. The first chip removal unit 2 will filter and discharge the upper floating chips in the chip liquid flowing through the first cleaning tank 12, the second chip removal unit 3 removes the intermediate suspended chips in the chip liquid in the second cleaning tank 13, and the third chip removal unit 4 removes the bottom sediment chips in the chip liquid in the second cleaning tank 13.

[0048] When the chip fluid of a high-chip removal machine tool is being discharged, the chip fluid used by each machine tool is discharged into the conveying channel 11, and then collected into the first cleaning tank 12 through the conveying channel 11, and then the upper floating chips in the chip fluid are discharged through the first chip removal unit 2. After the initial chip removal operation, the chip fluid enters the second cleaning tank 13, and then the bottom sediment chips in the chip fluid are discharged from the chip fluid through the third chip removal unit 4, and then the intermediate suspended chips are discharged from the chip fluid through the second chip removal unit 3, thereby realizing the chip removal of waste chips in the chip fluid, so that the chip fluid can be reused again, and at the same time, by performing chip removal three times according to the characteristics of different waste chips, the chip removal efficiency of the high-chip removal machine tool is improved.

[0049] Reference Figure 2 、 Figure 3The first chip removal unit 2 includes a material transport box 21 and a first conveyor belt 22. The material transport box 21 is laid flat in the first cleaning trough 12. A collection vehicle 14 is provided on the foundation layer 1. One end of the material transport box 21 first extends obliquely upward, and then extends horizontally to the top of the collection vehicle 14. A discharge port 211 is provided on the bottom wall of the material transport box 21. The discharge port 211 is located above the collection vehicle 14. The first conveyor belt 22 is slidably arranged in the material transport box 21. A motor is provided on the material transport box 21. The motor drives the first conveyor belt 22 to move in the material transport box 21 through a number of rotating rollers. Each conveying channel 11 is connected to the material transport box 21. The outlet of the conveying channel 11 is arranged above the first conveyor belt 22, and the other end of the first conveyor belt 22 extends to the top of the discharge port 211. The first conveyor belt 22 is provided with a plurality of screening holes 212, and the aperture of the screening holes 212 is smaller than the particle size of the upper floating debris. The opposite side walls of the material transport box 21 are provided with a drainage port 213 and a filter screen 214, and the filter screen 214 covers the drainage port 213. A plurality of baffles 23 are fixedly provided on the first conveyor belt 22, and each baffle 23 is arranged along the width direction of the first conveyor belt 22, and a plurality of baffles 23 are evenly arranged along the length direction of the first conveyor belt 22.

[0050] When the cutting liquid is discharged, the cutting liquid is transported to the material box 21 through the conveying channel 11, and then flows to the first conveyor belt 22. The upper floating chips in the cutting liquid are retained on the first conveyor belt 22 through the screening effect of the screening holes 212, and the cutting liquid flows into the second cleaning trough 13 through the discharge port 213. At the same time, the filter screen 214 can effectively prevent the waste chips screened out on the first conveyor belt 22 from flowing into the second cleaning trough 13. Then, the first conveyor belt 22 is driven by the motor to move, and the first conveyor belt 22 drives the waste chips to move to the discharge port 211, and then the waste chips fall into the collection vehicle 14 from the discharge port 211, thereby realizing the discharge of the upper floating chips in the cutting liquid. The waste chips are discharged by the first conveyor belt 22, which can reduce the workload of manual chip removal; the waste chips are pushed by the blocking bar 23, which can effectively prevent the waste chips from falling along the first conveyor belt 22 on the slope, thereby improving the stability of the first conveyor belt 22 in conveying waste chips.

[0051] Reference Figure 1 、 Figure 4The second chip removal unit 3 includes a pumping unit 31, a storage box 32 and a filter layer 33. The pumping unit 31 in this embodiment is a plurality of centrifugal pumps, which can also be screw pumps in other embodiments. The water outlet of each centrifugal pump is provided with a water pipe 34, the storage box 32 is arranged on the foundation base 1, and a water inlet is provided on the storage box 32. The filter layer 33 is arranged at the water inlet. The filter layer 33 is a mesh layer. The mesh diameter of the filter layer 33 is smaller than the maximum particle size of particles that can be contained in the recycled cutting liquid. A part of the water pipe 34 extends to the top of the filter layer 33, and the water outlet on the water pipe 34 faces the filter layer 33. Another part of the water pipe 34 extends to the front end of the waste liquid inflow of the conveying channel 11. The water pipe 34 is inserted into the conveying channel 11 and is connected to the conveying channel 11. A reflux pump 35 and a reflux pipe 36 are provided on the storage box 32. The reflux pump 35 and the reflux pipe 36 return the cutting liquid in the storage box 32 to the machine tool.

[0052] Reference Figure 4 、 Figure 5 and Figure 6 The third chip removal unit 4 includes a conveying box 41 and a chip cleaning member 42. The conveying box 41 is laid flat on the bottom wall of the second cleaning trough 13. One end of the conveying box 41 first extends obliquely upward, and then extends horizontally to the top of the collection vehicle 14. A drop opening 411 is provided on the bottom wall of the conveying box 41. The drop opening 411 is provided above the collection vehicle 14. In this embodiment, the chip cleaning member 42 includes a second conveyor belt 4211 and a plurality of push strips 4212. The second conveyor belt 4211 is slidably arranged in the conveying box 41. A motor is provided on the conveying box 41. The motor drives the second conveyor belt 4211 to slide in the conveying box 41 by rotating the roller. One end of the conveying box 41 extends To the top of the blanking port 411, each push bar 4212 is arranged along the width direction of the second conveyor belt 4211, and multiple push bars 4212 are arranged along the length direction of the second conveyor belt 4211. A guide groove 4213 is provided on the bottom wall of the first cleaning groove 12 and is connected to the second cleaning groove 13. The guide groove 4213 is located below the drain port 213, and a first guide surface 4214 is provided on the bottom wall of the guide groove 4213. The first guide surface 4214 is inclined and recessed toward the direction of the conveying box 41. A plurality of second guide surfaces 4215 are provided on the bottom wall of the second cleaning groove 13, and each second guide surface 4215 is inclined and recessed toward the conveying box 41.

[0053] When the cutting liquid flows from the first cleaning trough 12 into the second cleaning trough 13, the cutting liquid first enters the guide groove 4213 from the discharge port 213, and then flows into the second cleaning trough 13 along the first guide surface 4214. Through the setting of the first guide surface 4214, the waste chips precipitated in the cutting liquid can flow into the conveying box 41 along the first guide surface 4214, and then the cutting liquid flows toward the pumping unit 31. In the process of the cutting liquid flowing toward the pumping unit 31, the bottom sediment chips in the cutting liquid settle into the conveying box 41 under the action of its own gravity, and finally settle onto the second conveyor belt 4211. At this time, the second conveyor belt 4211 is driven to slide, and the second conveyor belt 4211 transports the precipitated bottom sediment chips to the drop port 411, and then falls into the collection vehicle 14 from the drop port 411, thereby realizing the chip discharge of the bottom sediment chips in the cutting liquid. The push bar 4212 can improve the stability of the second conveyor belt 4211 in transporting waste chips.

[0054] The pumping unit 31 then pumps the cutting liquid in the second cleaning tank 13 to the entrance of the storage box 32. When the cutting liquid passes through the filter layer 33, the intermediate suspended chips are separated from the cutting liquid, so that the content of waste chips in the cutting liquid entering the storage box 32 meets the standard for reuse. The operator only needs to replace or clean the filter layer 33 regularly, thereby reducing the labor intensity of the workers.

[0055] At the same time, the pumping unit 31 pumps the cutting liquid in the second cleaning tank 13 into the conveying channel 11 through the water pipe 34, flushes the waste chips in the conveying channel 11, and can wash away the waste chips settled in the conveying channel 11; the cutting liquid in the storage box 32 is returned to the machine tool under the pumping of the reflux pump 35 and the reflux pipe 36 for use by the machine tool. During the circulation of the cutting liquid, it can protect the cutting liquid and effectively prevent the cutting liquid from stinking for a long time.

[0056] The implementation principle of a chip removal device applied to a machine tool with a high chip removal capacity in an embodiment of the present application is as follows: when processing the chip liquid discharged from the machine tool, the chip liquid generated by each machine tool is first collected through the conveying channel 11 and passed into the first cleaning trough 12, and then the upper floating chips in the chip liquid in the first cleaning trough 12 are discharged through the first chip removal unit 2, and then the treated chip liquid flows into the second cleaning trough 13, and the middle suspended chips in the second cleaning trough 13 are discharged through the second chip removal unit 3, and the bottom precipitated chips in the second cleaning trough 13 are discharged by the third chip removal unit 4, thereby realizing the chip removal of waste chips in the chip liquid. By performing chip removal three times according to the characteristics of different waste chips, the thickness of the waste chip layer during each chip removal can be reduced, thereby improving the chip removal efficiency of the machine tool with a high chip removal capacity.

[0061] The implementation principle of Example 2 is as follows: when the cutting liquid in the second cleaning tank 13 is processed, the bottom sediment chips in the cutting liquid are settled onto the third conveyor belt 4221, and then the third conveyor belt 4221 is turned on to transport the settled waste chips to the drop port 411 and drop them onto the collection vehicle 14 for collection. When the third conveyor belt 4221 moves, the third conveyor belt 4221 drives the collection net 4222 to move while collecting some waste chips suspended in the cutting liquid, and then unloads the collected waste chips from the drop port 411 together with the third conveyor belt 4221, so that while cleaning the bottom sediment chips, the middle suspended chips can be cleaned, thereby reducing the accumulation speed of waste chips on the filter chip layer 33, reducing the frequency of cleaning and replacing the filter chip layer 33, and further reducing the labor intensity of workers.

[0062] The scraping net 4222 is then pulled away from the collecting net 4222, and the scraping net 4222 is then pulled away from the collecting net 4222. The scraping net 4222 is then pulled away from the collecting net 4222, and the scraping net 4222 is then pulled away from the collecting net 4222. The third conveyor belt 4221 is in conflict, and then the brush 442 rotates and brushes off the waste debris attached to the third conveyor belt 4221. As the collecting net 4222 moves, the limit block 4226 slides to the other end of the limit arc groove 4225. At this time, the angle between the collecting net 4222 and the third conveyor belt 4221 reaches the minimum value, and then the collecting net 4222 pushes the cleaning cylinder 432 to move downward. At this time, the telescopic spring 443 is extended, and the telescopic spring 443 still pulls the bristles to fit the collecting net 4222, thereby realizing the collection of the waste debris on the third conveyor belt 4221 and the collecting net 4222, thereby reducing the return amount of the third conveyor belt 4221 returning to the second cleaning slot 13, and improving the cleaning efficiency of the third conveyor belt 4221 for the deposited waste debris; the brush 442 hits the cleaning rod 444 when rotating, which can knock off the waste debris attached to the brush 442.
