Description

Technical Field

[0001] The present invention belongs to the technical field of waste cleaning of milling machines, and particularly relates to a waste cleaning device and method for a milling machine for processing die steel blanks. Background Art

[0002] During the processing of die steel blanks, a milling machine is one of the commonly used processing equipment. The milling machine performs cutting processing on the die steel blank by the rotation of the milling cutter and the movement of the workpiece to obtain the required shape and size. However, a large amount of waste, such as steel chips, powder, etc., will be generated during the processing. If these wastes are not cleaned up in time, a series of problems will occur.

[0003] Traditional cleaning methods, such as manually using tools such as brooms and brushes for cleaning, are not only inefficient but also difficult to clean thoroughly. Although some milling machines are equipped with simple waste collection devices, such as setting a waste tray at the bottom of the milling machine, these devices cannot effectively collect fine steel chips and powder, and do not solve the problem of waste accumulation inside the workbench.

[0004] Therefore, in view of the existing structure and deficiencies, research and improvement are carried out to provide a waste cleaning device and method for a milling machine for processing die steel blanks, in order to achieve a more practical purpose. Summary of the Invention

[0016] A waste cleaning method for a die steel blank processing milling machine, using the waste cleaning device of the die steel blank processing milling machine, includes the following steps:

[0017] S1 When the milling machine is working, start the circulating pump, control the liquid in the recovery box to be sprayed out through the second cleaning pipes on both sides of the fixed beam. Through the angle of the second cleaning holes, the broken materials entering the fixed beam can automatically enter the recovery tank along the side wall of the placement groove under the flushing of the liquid, and then flow back to the recovery box through the recovery tank. The broken materials are automatically filtered and separated by the filter screen, and the liquid can be recycled;

[0018] S2 After the milling machine finishes its work, disassemble and separate the fixture, then control the fixed beam to rise and rotate 180 degrees. In this rotational way, the waste on the upper surface of the fixed beam can automatically fall into the placement groove. At the same time, the upper surface of the fixed beam rotates above the third cleaning pipe. At this time, turn on the third cleaning pipe to automatically wash the broken material impurities on the upper surface of the fixed beam through the third cleaning pipe. After the flushing is completed, control the fixed beam to rotate 180 degrees. At this time, the first cleaning pipe is turned on, which can wash the broken material on the surface of the placement groove again, so that the waste can automatically flow into the recovery tank. After the waste is rinsed, control the fixed beam to return to its initial position, and at this time the cleaning is completed.

[0019] Compared with the prior art, the present invention has the following technical effects:

[0020] The original fixed workbench is changed to a movable fixed beam. In this way, through the up and down movement and rotation of the fixed beam, the broken material on the upper surface of the fixed beam can automatically rotate and fall into the placement groove, realizing the automatic collection of the broken material on the upper surface of the fixed beam. The design of the second cleaning pipe enables the liquid sprayed from the second cleaning holes to automatically wash the broken material into the recovery tank during the work of the workbench, effectively preventing excessive accumulation of broken material between the fixed beams and realizing the timely recovery of waste. The design of the first cleaning pipe enables the broken material on the upper surface of the fixed beam to fall into the placement groove automatically after the fixed beam rises and rotates. It is also easy for the broken material to fall directly below the fixed beam. If not cleaned, it is easy to cause the accumulation of broken material. Therefore, the design of the first cleaning pipe enables the waste in the placement groove to enter the recovery tank more thoroughly after the fixed beam rises and rotates, preventing the accumulation of broken material;

[0021] The design of the third cleaning pipe enables the upper surface of the fixed beam to be automatically sprayed and washed through the third cleaning pipe after the fixed beam rises and rotates. This can not only make the broken material on the upper surface of the fixed beam fall more thoroughly, but also realize the automatic cleaning of the upper surface of the fixed beam.

[0037] Example 1, please refer to Figure 1 、 Figure 2 and Figure 3 、 Figure 7, A waste cleaning device for a die steel blank processing milling machine, which is applied to the milling machine. The milling machine includes a milling machine main body 1, a workbench 2, a fixture 11 and a milling cutter 12. The workbench 2 is arranged on the milling machine main body 1. The milling cutter 12 is movably arranged on the workbench 2. The fixture 11 is detachably connected to the workbench 2. A placement groove 21 is provided on the workbench 2. A plurality of uniformly distributed fixed beams 22 are arranged in the placement groove 21. The waste cleaning device includes a first cleaning pipe 221 and a second cleaning pipe 222. A recovery groove 25 is provided in the middle of the placement groove 21. Both sides of the recovery groove 25 are inclined. The fixed beam 22 is arranged in the placement groove 21 so that it can move up and down and rotate. The first cleaning pipe 221 is arranged at the bottom of the fixed beam 22, and a plurality of first cleaning holes are provided on the first cleaning pipe 221. The first cleaning holes are inclined, and the liquid sprayed out of the first cleaning holes is used to wash the scraps in the placement groove 21 into the recovery groove 25. The second cleaning pipe 222 is arranged on both sides of the fixed beam 22, and a plurality of second cleaning holes are provided on the second cleaning pipe 222. The second cleaning holes are used to wash the waste between the fixed beams 22 when the fixed beam 22 is working. A third cleaning pipe 24 is arranged in the placement groove 21 below the fixed beam 22. A plurality of third cleaning holes 241 are provided on the third cleaning pipe 24. The liquid sprayed out of the third cleaning holes 241 is used to wash the scraps on the surface after the fixed beam 22 rotates. A recovery box 3 is provided at the bottom of the milling machine main body 1. A filter screen 32 is arranged in the recovery box 3. The upper inlet of the recovery box 3 is communicated with the outlet of the recovery groove 25. A circulation pump 35 for liquid recycling is provided on one side of the recovery box 3 and is communicated. The output end of the circulation pump 35 is provided with an output pipe 37. The output pipe 37 is selectively communicated with the first cleaning pipe 221, the second cleaning pipe 222 and the third cleaning pipe 24. In this application, the milling cutter 12 can move back and forth in the XYZ three directions to realize the processing of the steel blank by the milling cutter 12. Since this is prior art, this application will not describe it in too much detail. A circulation pipe 38 is provided and communicated between the liquid inlet end of the circulation pump 35 and the recovery box 3.

[0038] The original fixed workbench 2 is changed to a movable type with a fixed beam 22. In this way, through the up-and-down movement and rotation of the fixed beam 22, the scraps on the upper surface of the fixed beam 22 can automatically rotate and fall into the placement groove 21, realizing the automatic collection of the scraps on the upper surface of the fixed beam 22. The design of the second cleaning pipe 222 enables the liquid sprayed from the second cleaning holes to automatically wash the scraps into the recovery tank 25 during the operation of the workbench 2, effectively preventing excessive accumulation of scraps between the fixed beams 22 and realizing the timely recovery of waste materials. The design of the first cleaning pipe 221 enables, after the fixed beam 22 rises and rotates, since the scraps on the upper surface of the fixed beam 22 will automatically fall into the placement groove 21, it is also easy for the scraps to fall directly below the fixed beam 22. If not cleaned, it is easy to cause accumulation of scraps. Therefore, the design of the first cleaning pipe 221 enables, after the fixed beam 22 rises and rotates, the waste materials in the placement groove 21 to enter the recovery tank 25 more thoroughly, preventing the accumulation of scraps.

[0039] The design of the third cleaning pipe 24 enables, after the fixed beam 22 rises and rotates, the upper surface of the fixed beam 22 to be automatically sprayed and washed through the third cleaning pipe 24. This can not only make the scraps on the upper surface of the fixed beam 22 fall more thoroughly, but also realize the automatic cleaning of the upper surface of the fixed beam 22.

[0040] In this embodiment, please refer to Figure 3 and Figure 5 , a plurality of limiting grooves 243 are provided at the bottom of the placement groove 21. A limiting plate 244 that slides and is sealingly connected is provided in the limiting grooves 243. A protruding plate 220 that is fixedly connected and engages with the limiting grooves 243 is provided at the bottom of the fixed beam 22. The third cleaning pipe 24 is arranged at the bottom of the limiting plate 244, and a plurality of through holes communicating with the third cleaning holes 241 are provided on the limiting plate 244. A jacking spring 242 for driving the limiting plate 244 to eject and be flush with the placement groove 21 is provided in the limiting grooves 243. The design of the limiting plate 244 and the jacking spring 242 can drive the limiting plate 244 to automatically rise through the jacking spring 242, realizing that the sides of the placement groove 21 can remain flat during the cleaning process, effectively preventing the accumulation of scraps. At the same time, the design of the limiting grooves 243 and the protruding plate 220 can, through the engagement of the protruding plate 220 with the limiting grooves 243, make the fixed beam 22 stable during operation by the way of the engagement of the protruding plate 220 with the limiting grooves 243 during the use of the fixed beam 22, thus ensuring the stability of the fixture 11.

[0041] In this embodiment, a connecting hose is provided at the water inlet end of the third cleaning pipe 24, and a pressing plate fixedly connected to the bottom of the limiting plate 244 and used for pressing the connecting hose is provided. With such a design, during the operation of the fixed beam 22, the connecting hose can be pressed through the pressing plate, thereby realizing the automatic sealing of the third cleaning pipe 24.

[0042] In this embodiment, please refer to Figure 2 and Figure 3 A plurality of fixedly connected hydraulic rods 231 are provided on both sides of the placement groove 21. A fixed block 23 is fixedly connected to the end of the hydraulic rod 231. The fixed beam 22 is rotatably and sealingly connected to the fixed block 23.

[0043] In this embodiment, please refer to Figure 6 , rotating shafts 236 fixedly connected to both ends of the fixed beam 22 are provided. A connecting groove for rotatably connecting with the rotating shaft 236 is provided on one side of the fixing plate. A torsion spring 232 for driving the rotating shaft 236 to rotate to the initial position is provided in the connecting groove. A fixedly connected and bendable connecting member 233 is provided on the rotating shaft 236. The connecting member 233 is wound around the rotating shaft 236, and the extending end of the connecting member 233 movably passes through the side wall of the connecting groove and is fixedly connected to the bottom of the placement groove 21.

[0044] Since one end of the connecting member 233 is fixedly connected to the rotating shaft 236 and the connecting member 233 is arranged in a wound shape around the rotating shaft 236, with such a design, when the fixed block 23 drives the fixed beam 22 to rise, the connecting member 233 can automatically pull the rotating shaft 236 to rotate, thereby realizing the automatic rotation of the fixed beam 22. At the same time, with the design of the torsion spring 232, when the fixed block 23 descends, through the elasticity of the torsion spring 232, the automatic rotation of the fixed beam 22 to restore to the initial position is realized. Compared with the chain drive method, the structure is simpler and the cost is lower.

[0045] In this embodiment, the rotation of the rotating shaft 236 can also be controlled by using a chain and a motor.

[0046] In this embodiment, please refer to Figure 6 , a connecting ring groove 234 is provided on the fixing plate at one end of the fixed beam 22. A first hole 224 and a second hole 223 communicating with the connecting ring groove 234 are provided at one end of the fixed beam 22. The first hole 224 communicates with the first cleaning pipe 221, and the second hole 223 communicates with the second cleaning pipe 222. A communicating sealing groove 2254 is provided between the first hole 224 and the second hole 223. A sealing plate 225 that can move up and down and is used for selectively sealing the first hole 224 and the second hole 223 is provided in the sealing groove 2254. A communicating pipe 235 communicating with the output pipe 37 is provided at one end of the connecting ring groove 234.

[0047] In this embodiment, an electric hydraulic push rod can also be used to control the up and down movement of the sealing plate 225.

[0048] In this embodiment, please refer to Figure 6 , a reset groove is provided on one side of the sealing groove 2254 and is communicated therewith. A reset plate 2252 is slidably connected in the reset groove. The reset plate 2252 is fixedly connected to the sealing plate 225. A reset spring 2251 for driving the sealing plate 225 to automatically return to its initial position is provided in the reset groove. One end of the sealing plate 225 is fixedly connected with a ejector rod 2253. One end of the ejector rod 2253 movably passes through the sealing groove 2254. After the ejector rod 2253 contacts and presses against the placement groove 21, the sealing plate 225 is driven by the reset plate 2252 to seal the first hole 224. When the fixed beam 22 is working, liquid can only enter the second cleaning pipe 222 through the second hole 223 to wash the waste between the fixed beams 22. After the ejector rod 2253 is separated from the placement groove 21, the reset spring 2251 drives the sealing plate 225 to move, so that the first hole 224 is opened and the second hole 223 is sealed, so that the liquid can only wash the waste on the placement groove 21 through the first cleaning pipe 221.

[0049] In this embodiment, please refer to Figure 6 , a gravity groove is provided at the bottom of the first hole 224. A gravity plate 226 is slidably and sealingly connected in the gravity groove. After the fixed beam 22 rotates 180 degrees, the gravity plate 226 can automatically fall due to gravity to seal the first hole 224. Such a design can solve the problem that when the fixed beam 22 rotates 180 degrees and only the third cleaning pipe 24 needs to clean the surface of the fixed beam 22, the first hole 224 cannot be sealed.

[0050] In this embodiment, please refer to Figure 3 and Figure 5 , a screw conveyor blade 251 that is rotatable and used for waste conveying is provided in the recovery tank 25. A conveying motor for driving the screw conveyor blade 251 to rotate is provided on the milling machine main body 1.

[0051] In this embodiment, please refer to Figure 1 and Figure 7, a recovery pipe 31 is provided at the feeding end of the recovery box 3, and the recovery pipe 31 is communicated with the discharging end of the recovery tank 25. One end of the filter screen 32 is rotatably connected to the side wall of the recovery box 3, and a discharging port 33 is provided on the side wall of the recovery box 3 at the other end of the filter screen 32. A rotatably connected discharging plate 34 is provided in the discharging port 33. When the discharging plate 34 rotates vertically to seal the discharging port 33, the upper end of the discharging plate 34 supports and fixes the other end of the filter screen 32. The width of the discharging plate 34 is greater than the width of the filter screen 32, and a handle plate is provided on the discharging plate 34. Such a design can better control the rotation of the discharging plate 34.

[0052] The design of the discharging plate 34 enables the discharging plate 34 to seal the discharging port 33 when it is in a vertical state, and at the same time can effectively support the other end of the filter screen 32 to ensure the normal use of the filter screen 32. When the discharging plate 34 rotates, the discharging plate 34 can not only normally open the discharging port 33, but also serve as an extension plate after the filter screen 32 rotates, making up for the problem of insufficient length of the filter screen 32 after rotation, resulting in the falling of broken materials, so that the broken materials can be discharged better.

[0053] In this embodiment, please refer to Figure 7 , a drying fan 36 is further provided at the other end of the recovery box 3, and the drying fan 36 is communicated with an output pipe 37.

[0054] A waste cleaning method for a die steel blank processing milling machine, using the waste cleaning device of the die steel blank processing milling machine, includes the following steps:

[0055] S1 When the milling machine is working, at this time, the fixed beam 22 is located in the placement groove 21, the extrusion plate squeezes the connecting hose to seal the third cleaning pipe 24, and the ejector rod 2253 is squeezed at this time, so that the sealing plate 225 seals the first cleaning pipe 221. Start the circulation pump 35, and control the liquid in the recovery box 3 to be sprayed out through the second cleaning pipes 222 on both sides of the fixed beam 22. Through the angle of the second cleaning holes, the broken materials entering the fixed beam 22 can automatically enter the recovery tank 25 along the side wall of the placement groove 21 under the flushing of the liquid, and then flow back to the recovery box 3 through the recovery tank 25. The broken materials are automatically filtered and separated by the filter screen 32, and the liquid can be recycled, effectively preventing the accumulation of broken materials;

[0056] S2 After the milling machine finishes its work, disassemble and separate the fixture 11, and then control the fixed beam 22 to rise through the hydraulic rod 231. At this time, the ejecting spring 242 can drive the limit plate 244 to rise automatically, making the limit plate 244 flush with the placement groove 21. The extrusion plate is separated from the connecting hose, and the third cleaning pipe 24 is opened. At the same time, due to the movement of the fixed beam 22, the ejector rod 2253 moves automatically under the action of the return spring 2251, so that the sealing plate 225 seals the second cleaning pipe 222, and the first cleaning pipe 221 is automatically opened. As the fixed beam 22 continues to rise, at this time, the connecting piece 233 can drive the rotating shaft 236 to rotate. By controlling the length of the connecting piece 233, the fixed beam 22 can be automatically rotated 180 degrees. At this time, under the action of gravity, the gravity plate 226 can move downward automatically, so that the gravity plate 226 automatically closes the first cleaning pipe 221;

[0057] And through the rotation method, the waste on the upper surface of the fixed beam 22 can automatically fall into the placement groove 21. At the same time, the upper surface of the fixed beam 22 rotates above the third cleaning pipe 24. At this time, only need to control the circulating pump 35 to start, and the liquid automatically flushes the broken material impurities on the upper surface of the fixed beam 22 through the third cleaning pipe 24. After the flushing is completed; control the fixed plate to move downward to the set position. At this time, the fixed beam 22 can automatically rotate 180 degrees under the action of the torsion spring 232, making the upper surface of the fixed beam 22 face upward. At this time, under the action of gravity, the gravity plate 226 can automatically return to its initial position, making the first cleaning pipe 221 open. At this time, the liquid coming out of the circulating pump 35 can be sprayed out through the first cleaning pipe 221 and the third cleaning pipe 24 at the same time, and can flush the broken materials on the bottom surfaces of the placement groove 21 and the fixed beam 22 again, so that the waste can automatically flow into the recovery tank 25. After the waste is washed, turn off the circulating pump 35 to make the liquid in the pipeline flow back to the recovery tank 3. At this time, control the drying fan 36 to start, so that the hot air blows on the fixed beam 22 and the placement groove 21. Using the wind force can not only make the broken materials better enter the recovery tank 25, but also the wind force can dry the liquid in the fixed beam 22 and the placement groove 21 faster, keeping the whole dry. During the blowing process, the up and down movement of the fixed block 23 can also be continuously controlled, so that the fixed beam 22 can rotate continuously. The rotation can better throw off the liquid on the surface of the fixed beam 22, and at the same time can make the airflow blow more evenly;

[0058] After drying, continue to control the original fixed beam 22 to return to its initial position through the hydraulic rod 231, so that the convex plate 220 enters the limit groove 243 and is clamped and fixed. The extrusion of the convex plate 220 on the limit plate 244 can drive the extrusion plate to extrude the connecting hose, so that the third cleaning pipe is automatically closed. After being extruded, the ejector rod 2253 can drive the sealing plate 225 to move, opening the second cleaning pipe 222 and closing the first cleaning pipe 221. At this time, the liquid in the circulation pump 35 can only be ejected through the second cleaning pipe, so that when the fixed beam 22 is working normally, it continues to clean the waste.
