Description

Technical Field

[0001] The invention relates to the technical field of metal processing, in particular to a metal cutting device capable of recycling waste chips. Background Art

[0002] Metal cutting is the process of using a cutting tool to remove excess material from a blank or workpiece, creating chips to achieve a desired geometry, size, and surface quality. Metal cutting utilizes the relative motion between the workpiece and the tool, using the tool's cutting edge to remove excess metal from the workpiece, resulting in a component of a desired quality.

[0003] However, in the prior art, when a metal cutting device is performing cutting work, a large amount of cutting waste chips often splash everywhere, and need to be manually collected and sorted after the work is completed. This not only increases the labor intensity of the workers, but also the metal waste chips are often not recovered thoroughly enough, resulting in a waste of resources. For example, Chinese invention patent CN108772157A discloses a waste recovery device for cutting machine tool production and processing. In this invention, only scattered waste chips can be recovered, and entangled metal waste chips cannot be recovered. Another example is a cutting chip recovery and processing device disclosed in Chinese invention patent CN110961235A. Although it can solve the problem of entanglement of waste chips, it cannot classify different types of metal waste chips for recycling. A large amount of manual processing is still required later, which is inefficient. Summary of the Invention

DETAILED DESCRIPTION

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts also fall within the scope of protection of the present invention.

[0037] like Figure 1-4 As shown, the present invention provides a metal cutting device capable of recycling waste chips, comprising a cutting device 1 and a recycling device 2. The cutting device 1 comprises a chuck box 11, a tool holder box 12, a workbench 13 and a cutting frame 14 between the chuck box 11 and the tool holder box 12, a workpiece pallet 15 being provided on the workbench 13, and an air cooling device 16 being installed above the workbench 13. The recycling device 2 comprises two negative pressure collection devices 21 located below the workbench 13 and a waste chip crushing device 22 between the two negative pressure collection devices 21, a waste chip transfer device 23 being provided below the waste chip crushing device 22, and two waste chip transfer boxes 24 being provided below the waste chip transfer device 23, each waste chip transfer box 24 being connected to a pressing device 25, and the outlet of each pressing device 25 being connected to a waste chip box 26.

[0038] When the metal cutting device capable of recycling waste chips is in use, the cutting device 1 is used to process the metal workpiece, and the recycling device 2 is used to collect and process the cut metal waste chips. The chuck box 11 is located on the left side, on which a chuck 110 is installed for clamping the workpiece. The tool holder box 12 is located on the right side, and a tool holder 120 is provided in the tool holder box 12 for clamping the tool, and processing the workpiece clamped on the chuck box 11 through the tool. The workbench 13 is located between the chuck box 11 and the tool holder box 12. A workpiece pallet 15 is provided on the workbench 13 for placing the metal workpiece. The cutting frame 14 provided above the workbench 13 is used to process the workpiece on the workpiece pallet 15. The cutting frame 14 moves through the second slide rail 123 between the chuck box 11 and the tool holder box 12.

[0039] The tool holder 120 moves via a first slide rail 121 provided on the workbench 13. The workpiece tray 15 is located below the first slide rail 121 and does not affect the movement of the tool holder 120. A fan 122 is also installed in the tool holder box 12 to prevent metal scraps from entering the tool holder box 12.

[0040] The air cooling device 16 is used to blow out cooling gas to cool the metal workpiece being processed, and can also purge the workbench 13 at the same time.

[0041] The negative pressure collection device 21 in the recovery device 2 is used to initially collect the cut metal scraps. The scrap crushing device 22 is used to disperse the scrap metal scraps collected in the negative pressure collection device 21 for subsequent separation. The scrap metal transfer device 23 is used to classify the scrap metal scraps dispersed by the scrap crushing device 22 and transfer them to the scrap transfer box 24. The scrap metal scraps in the scrap transfer box 24 are compacted by the compacting device 25 and then discharged into the scrap box 26 for storage.

[0042] The present invention not only recovers the metal scraps generated during the cutting process, but also roughly separates the metal scraps through the coordinated action of the negative pressure collection device 21, the scrap crushing device 22, the scrap dividing device 23, and the pressing device 25 in the recovery device 2, thereby improving the efficiency of metal scrap recovery and sorting, reducing the labor intensity of workers, and avoiding waste of resources.

[0043] like Figure 5-7As shown, further, the negative pressure collection device 21 includes a plurality of slot blocks 210 arranged in parallel on the side of the workpiece pallet 15, a collection slot 211 is formed between two adjacent slot blocks 210, and a negative pressure collection box 212 is provided below the slot blocks 210. A filter layer 213 is provided at the bottom of the negative pressure collection box 212, and a plurality of air holes 214 are provided below the filter layer 213 and on the bottom plate of the negative pressure collection box 212, and the air holes 214 are connected to the negative pressure fan 215. A baffle 216 is provided on the side of the negative pressure collection box 212 close to the waste crushing device 22, and the baffle 216 is hinged to the bottom of the workbench 13. A rubber layer is provided at the bottom of the baffle 216. A first push plate 217 is also provided on the side of the negative pressure collection box 212 away from the baffle 216, and the first push plate 217 is connected to the first cylinder 219 through a first telescopic rod 218 that passes through the side wall of the negative pressure collection box 212.

[0044] The negative pressure collection device 21 comprises multiple slots 210 arranged parallel to the sides of the workpiece tray 15 and a negative pressure collection box 212 positioned below the slots 210. When cutting a metal workpiece, the negative pressure blower 215 is activated, creating a negative pressure zone within the negative pressure collection box 212. Simultaneously, the air cooling device 16 purges the cut metal waste through the collection slots 211 and into the negative pressure collection box 212.

[0045] The top of the tank block 210 is tilted, and the entrance of the collection tank 211 is low-side, which is convenient for collecting metal scraps. The bottom of the negative pressure collection box 212 is paved with a filter layer 213, which is used to prevent metal scraps from entering the negative pressure fan 215.

[0046] A baffle 216 is provided on one side of the negative pressure collection box 212 near the waste crushing device 22. The baffle 216 is hinged to the bottom of the workbench 13. The baffle 216 is used to separate the negative pressure collection box 212 from the waste crushing device 22. After a certain amount of metal scrap has been collected in the negative pressure collection box 212 or for a certain period of time, the first cylinder 219 is activated, driving the first telescopic rod 218 to push the first push plate 217. The first push plate 217 pushes the metal scrap to lift the baffle 216, and the metal scrap then falls into the waste crushing device 22. After the push is completed, the first telescopic rod 218 and the first push plate 217 are retracted, and the baffle 216 falls back, separating the negative pressure collection box 212 from the waste crushing device 22 again.

[0047] like Figure 5-7 As shown, further, the waste chip crushing device 22 includes a crushing area 220 located between the two negative pressure collection boxes 212, a crusher 221 is installed in the crushing area 220, and a gate valve 222 is installed at the outlet below the crushing area 220.

[0048] The metal scraps generated during the cutting process vary in shape. After being collected and placed in negative pressure collection device 21, they may become stuck together. Therefore, scrap crushing device 22 crushes and disperses the scraps for subsequent separation. Once crushing is complete, gate valve 222 below crushing zone 220 is opened, allowing the scraps to fall into transport box 230.

[0049] like Figure 8-10 As shown, the waste separation and transfer device 23 further comprises a plurality of transport boxes 230 arranged in parallel below the waste crushing device 22. Each transport box 230 is equipped with a conveyor belt 231. Waste outlets 232 are provided at both ends of the bottom of the transport box 230, and movable baffles 233 are installed on the waste outlets 232. An electromagnetic suction cup 234 is also installed above the conveyor belt 231. Furthermore, the crushing zone 220 is located above one end of the conveyor belt 231, and the electromagnetic suction cup 234 is located above the rest of the conveyor belt 231. Furthermore, the conveyor belt 231 is a spiral conveyor belt driven by a motor 235 outside the transport box 230.

[0050] The crushed metal scraps pass through the gate valves 222 and enter the transport box 230. Each transport box 230 has scrap outlets 232 at both ends of its bottom, each equipped with movable baffles 233. Electromagnetic suction cups are installed above the conveyor belt 231, excluding the gate valves 222. Once the scrap metal enters the transport box 230, a motor 235 drives the conveyor belt 231, which transports the scrap metal forward. At this point, the movable baffles 233 at both scrap outlets 232 are closed. As the spiral conveyor belt (conveyor belt 231) moves, the magnetic scrap metal is attracted by the electromagnetic suction cups 234, while the remaining non-magnetic scrap metal is transported to the other end of the spiral conveyor belt. To ensure a thorough separation of magnetic and non-magnetic scrap metal, the spiral conveyor belt can be rotated forward and backward multiple times to ensure that as much magnetic scrap metal as possible is attracted by the electromagnetic suction cups 234. During the final forward rotation, the movable flapper 233 on the side away from the gate valve 222 is opened, and the non-magnetic metal scraps are transported by the conveyor belt 231 and discharged through the corresponding scrap outlet 232. After the non-magnetic metal scraps are discharged, the flapper 233 on the other side is opened, and the electromagnetic suction cup 234 is closed, allowing the magnetic metal scraps to fall onto the conveyor belt 231. The conveyor belt 231 is then reversed, and the magnetic metal scraps are discharged through the corresponding scrap outlet 232.

[0051] like Figure 9-12As shown, two waste transfer boxes 24 are located on either side below the waste transfer device 23, and each waste transfer box 24 is simultaneously connected to the waste outlets 232 on one side of the multiple transport boxes 230. A discharge port 240 is defined on one side wall of the waste transfer box 24. A second push plate 241, shaped to match the discharge port 240, is located within the waste transfer box 24. The second push plate 241 is connected to a second cylinder 243 via a second telescopic rod 242 that extends through the other side wall of the waste transfer box 24. Furthermore, the pressing device 25 includes two pressing boxes 250, located outside the discharge port 240 and connected to each of the waste transfer boxes 24 in a one-to-one correspondence. A third air cylinder 251 is installed between the two compression boxes 250. The output end of the third air cylinder 251 is connected to a third push plate 253 inside the compression box 250 via a third telescopic rod 252 that extends through the side wall of the compression box 250. Furthermore, a slag discharge port 254 is defined on the end of the long side panel of the compression box 250, away from the third air cylinder 251. A second gate valve 255 is installed at this port. Furthermore, a fourth push plate 256, a fourth telescopic rod 257, and a fourth air cylinder 258 are provided at the end of the compression box 250, corresponding to the port 254.

[0052] The second cylinder 243 drives the second telescopic rod 242, which pushes the second push plate 241 to push the metal scraps in the scrap transfer box 24 through the discharge port 240 and into the compression box 250. At this point, the second push plate 241 does not retract but remains at the discharge port 240, forming a sealed space between it and the compression box 250. Simultaneously, the third cylinder 251 drives the third telescopic rod 252, which pushes the third push plate 253 forward, pushing and tightly compressing the metal scraps between the compression box 250 and the second push plate 241. After compression is complete, the second and third push plates 241, 253, retract, the second gate valve 255 opens, and the fourth push plate 256 drives the fourth telescopic rod 257 and the fourth cylinder 258 to discharge the compressed metal scrap blocks through the slag discharge port 254 into the scrap box 26.

[0053] like Figure 13 As shown, further, each waste box 26 is connected to the compression box 250 in a one-to-one correspondence through the second gate valve 255. A ramp 260 is installed at the entrance of the waste box 26, and the end of the ramp 260 close to the entrance of the waste box 26 is the high end, and the end away from the entrance of the waste box 26 is the bottom end.

[0054] Each waste box 26 is communicated with the pressing box 250 in a one-to-one correspondence through the second gate valve 255. Two groups of pressing boxes 250 and waste boxes 26, one group presses and places magnetic waste, and one group presses and places non-magnetic waste.

[0055] A ramp 260 is installed at the entrance of the waste box 26. When the metal scraps enter the waste box 26, they will slide down the ramp 260 and will not accumulate at the entrance of the waste box 26. After the device has been running for a period of time, the metal scraps in the waste box 26 can be taken out for unified treatment.

[0056] The following is the complete working principle of the present invention:

[0057] like Figure 1-13 As shown, when the metal cutting device that can recycle waste chips is used, a suitable cutting device 1 is selected according to the specific processing requirements. The tool holder box 12 is located on the right side. A tool holder 120 is provided in the tool holder box 12 for clamping the tool and processing the workpiece clamped on the chuck box 11 through the tool. The workbench 13 is located between the chuck box 11 and the tool holder box 12. A workpiece pallet 15 is provided on the workbench 13 for placing metal workpieces. The cutting rack 14 provided above the workbench 13 is used to process the workpiece on the workpiece pallet 15. The tool holder 120 is moved by a first slide rail 121 provided on the workbench 13. The workpiece pallet 15 is located below the first slide rail 121 and will not affect the movement of the tool holder 120. A fan 122 is also installed in the tool holder box 12. The operation of the fan 122 prevents metal waste chips from entering the tool holder box 12.

[0058] The air cooling device 16 is used to blow out cooling gas to cool the metal workpiece being processed, and can also be used to purge the workbench 13. The air source of the air cooling device 16 adopts a mixed gas source of low-temperature nitrogen (liquid nitrogen) and normal temperature air. The low-temperature nitrogen comes from a liquid nitrogen storage bottle, and the normal temperature air is extracted by a compressor. When in use, the liquid nitrogen is extracted from the outlet valve of the storage bottle, mixed with the normal temperature air in a certain proportion, and then sent to the air outlet pipeline of the air cooling device 16 for use. This is content well known to those skilled in the art and will not be elaborated here. A protective cover needs to be installed between the cutting device 1 and the recovery device 2, and an observation window is provided on the protective cover to facilitate observation of the processing process during processing (not shown in the figure).

[0059] When cutting a metal workpiece, the negative pressure blower 215 is activated, creating a negative pressure zone within the negative pressure collection box 212. Simultaneously, the air cooling device 16 purges the cut metal scraps through the collection trough 211 and into the negative pressure collection box 212. Once a certain amount of scrap metal has accumulated in the negative pressure collection box 212, or for a certain period of time, the first air cylinder 219 is activated, driving the first telescopic rod 218 to push the first push plate 217. This push plate 217 lifts the baffle 216, pushing the scrap metal into the scrap crushing device 22.

[0060] The scrap metal is broken up and dispersed in the scrap crushing device 22 for subsequent separation. Once crushing is complete, a gate valve 222 below the crushing zone 220 is opened, allowing the scrap metal to fall into a transport box 230. Crushing zone 220 is equipped with a crushing roller 223, which is connected to a crushing motor 224 outside the scrap crushing device 22. Crushing roller 223 is also equipped with multiple crushing blades 225 for agitating and crushing the scrap metal.

[0061] The crushed metal scraps pass through a gate valve 222 and enter a transport box 230. Inside the transport box 230, an electromagnetic suction cup 234 is located above the rear two-thirds of the conveyor belt 231 in its forward direction. A gate valve 222 (the scrap crushing device 22) is located above the front one-third. Once the metal scraps enter the transport box 230, a motor 235 drives the conveyor belt 231, which transports them forward. At this point, the movable baffles 233 at both scrap outlets 232 are closed. As the spiral conveyor belt (conveyor belt 231) moves, the magnetic metal scraps are attracted by the electromagnetic suction cup 234, while the remaining non-magnetic metal scraps are transported to the other end of the spiral conveyor belt. To ensure a thorough separation of magnetic and non-magnetic metal scraps, the spiral conveyor belt can be rotated forward and reversed multiple times to ensure that as much of the magnetic metal scrap as possible is attracted by the electromagnetic suction cup 234. During the final forward rotation, the movable flapper 233 on the side away from the gate valve 222 is opened, and the non-magnetic metal scraps are transported by the conveyor belt 231 and discharged through the corresponding scrap outlet 232. After the non-magnetic metal scraps are discharged, the flapper 233 on the other side is opened, and the electromagnetic suction cup 234 is closed, allowing the magnetic metal scraps to fall onto the conveyor belt 231. The conveyor belt 231 is then reversed, and the magnetic metal scraps are discharged through the corresponding scrap outlet 232.

[0062] The separated magnetic metal scraps and non-magnetic metal scraps enter different scrap transfer boxes 24 and are compressed by their corresponding compression boxes 250 , and finally enter the scrap box 26 for storage.

[0063] During compression, the second cylinder 243 drives the second telescopic rod 242, which pushes the second push plate 241 to push the metal scraps in the scrap transfer box 24 through the discharge port 240 and into the compression box 250. At this point, the second push plate 241 does not retract but remains at the discharge port 240, forming a sealed space between it and the compression box 250. Simultaneously, the third cylinder 251 drives the third telescopic rod 252, which pushes the third push plate 253 forward, pushing and tightly compressing the metal scraps between the compression box 250 and the second push plate 241. After compression is complete, the second and third push plates 241, 253, retract, the second gate valve 255 opens, and the fourth push plate 256 drives the fourth telescopic rod 257 and the fourth cylinder 258 to discharge the compressed metal scrap blocks through the slag discharge port 254 into the scrap box 26.

[0064] A ramp 260 is installed at the entrance of the waste box 26. When the metal scraps enter the waste box 26, they will slide down the ramp 260 and will not accumulate at the entrance of the waste box 26. After the device has been running for a period of time, the metal scraps in the waste box 26 can be taken out for unified treatment.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some or all of the technical features therein can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
