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] Cutting refers to the process of using cutting tools to cut off the excess material layer on the blank or workpiece into chips, so that the workpiece can obtain the specified geometric shape, size and surface quality. Metal cutting is the process of using the relative motion between the workpiece and the tool to remove the excess metal layer on the workpiece with the cutting edge on the tool to obtain parts with a certain processing quality.

[0003] However, in the prior art, when the metal cutting device is performing cutting work, a large amount of cutting waste chips often splash everywhere, and need to be collected and sorted manually after the work is completed, which not only increases the labor intensity of the workers, but also the metal waste chips are often not recycled thoroughly, 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.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present invention.

[0024] 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 is arranged on the workbench 13, and an air cooling device 16 is also 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 dividing device 23 is arranged below the waste chip crushing device 22, and two waste chip transfer boxes 24 are arranged below the waste chip dividing device 23, each waste chip transfer box 24 is connected to a pressing device 25, and the outlet of each pressing device 25 is connected to a waste chip box 26.

[0025] When the metal cutting device capable of recycling waste chips is in use, the cutting device 1 is used to process metal workpieces, 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 arranged in the tool holder box 12 for clamping the tool, and the workpiece clamped on the chuck box 11 is processed by the tool. The workbench 13 is located between the chuck box 11 and the tool holder box 12, and a workpiece pallet 15 is arranged on the workbench 13 for placing metal workpieces. The cutting frame 14 arranged above the workbench 13 is used to process the workpiece on the workpiece pallet 15, and the cutting frame 14 moves through the second slide rail 123 between the chuck box 11 and the tool holder box 12.

[0026] The tool rest 120 moves via a first slide rail 121 disposed on the workbench 13, and the workpiece tray 15 is located below the first slide rail 121 and does not affect the movement of the tool rest 120. A fan 122 is also installed in the tool rest box 12, and the operation of the fan 122 prevents metal scraps from entering the tool rest box 12.

[0027] 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.

[0028] The negative pressure collection device 21 in the recovery device 2 is used for preliminary collection of the cut metal scraps. The scrap crushing device 22 is used for dispersing the metal scraps collected in the negative pressure collection device 21 for subsequent separation. The scrap transfer device 23 is used for classifying the metal scraps dispersed by the scrap crushing device 22 and transferring them to the scrap transfer box 24. The metal scraps in the scrap transfer box 24 are compressed by the compression device 25 and then discharged into the scrap box 26 for storage.

[0029] The present invention not only realizes the recovery of metal waste generated in the cutting process, but also roughly classifies the metal waste through the coordinated action of the negative pressure collection device 21, the waste crushing device 22, the waste transfer device 23 and the pressing device 25 in the recovery device 2, thereby improving the efficiency of metal waste recovery and sorting, reducing the labor intensity of workers and avoiding waste of resources.

[0030] like Figure 5-7 As shown, further, the negative pressure collection device 21 includes a plurality of slot blocks 210 arranged in parallel on the side of the workpiece tray 15, a collection slot 211 is formed between two adjacent slot blocks 210, and a negative pressure collection box 212 is arranged below the slot blocks 210. A filter layer 213 is laid on the bottom of the negative pressure collection box 212, and a plurality of air holes 214 are opened 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 arranged 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 arranged at the bottom of the baffle 216. A first push plate 217 is also arranged 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 penetrates the side wall of the negative pressure collection box 212.

[0031] The negative pressure collection device 21 includes a plurality of slot blocks 210 arranged in parallel on the side of the workpiece tray 15 and a negative pressure collection box 212 arranged below the slot blocks 210. When cutting the metal workpiece, the negative pressure fan 215 is started, and a negative pressure area is formed in the negative pressure collection box 212 under the action of the negative pressure fan 215. At the same time, in conjunction with the purge of the air cooling device 16, the cut metal waste is sucked into the negative pressure collection box 212 through the collection slot 211.

[0032] The top of the tank block 210 is inclined, and the entrance of the collecting tank 211 is at a low side, which is convenient for collecting metal scraps. A filter layer 213 is laid at the bottom of the negative pressure collecting box 212, and the filter layer 213 is used to prevent metal scraps from entering the negative pressure fan 215.

[0033] A baffle 216 is provided on one side of the negative pressure collection box 212 near the waste crushing device 22, and 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. When a certain amount of metal waste is collected in the negative pressure collection box 212 or a certain period of time, the first cylinder 219 is started, and the first cylinder 219 drives the first telescopic rod 218 to push the first push plate 217, and the first push plate 217 pushes the metal waste to lift the baffle 216, and the metal waste falls into the waste crushing device 22. After the pushing is completed, the first telescopic rod 218 and the first push plate 217 are retracted, and the baffle 216 falls back, and the negative pressure collection box 212 and the waste crushing device 22 are separated again.

[0034] like Figure 5-7 As shown, further, the waste chip crushing device 22 includes a crushing area 220 located between 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 .

[0035] The metal scraps generated during the cutting process of the metal workpiece have different shapes. After being collected and entering the negative pressure collection device 21, the metal scraps may be adhered to each other. Therefore, the scrap crushing device 22 is used to crush and disperse the metal scraps for subsequent separation. When the crushing is completed, the gate valve 222 below the crushing area 220 is opened, and the metal scraps fall into the transport box 230.

[0036] like Figure 8-10 As shown, further, the waste chip distribution device 23 includes a plurality of transport boxes 230 arranged in parallel below the waste chip crushing device 22, each transport box 230 is installed with a conveyor belt 231, and waste chip outlets 232 are opened at both ends of the bottom of the transport box 230, and movable baffles 233 are installed on the waste chip outlets 232, and an electromagnetic suction cup 234 is also installed above the conveyor belt 231. Further, the crushing area 220 is located above the end of one side of the conveyor belt 231, and the electromagnetic suction cup 234 is located above the rest of the conveyor belt 231. Further, the conveyor belt 231 is a spiral conveyor belt, and the spiral conveyor belt is driven by a motor 235 outside the transport box 230.

[0037] The crushed metal scraps enter the transport box 230 through the gate valve 222. Both ends of the bottom of each transport box 230 are provided with scrap outlets 232, and movable baffles 233 are installed on the scrap outlets 232. Electromagnetic suction cups are installed above the conveyor belt 231 except for the gate valve 222. When the metal scraps enter the transport box 230, the motor 235 drives the conveyor belt 231, and the conveyor belt 231 transports the metal scraps forward. At this time, the movable baffles 233 at the two scrap outlets 232 are in a closed state. With the transportation of the spiral conveyor belt (conveyor belt 231), the magnetic metal scraps are adsorbed by the electromagnetic suction cup 234, and the remaining non-magnetic metal scraps are transported to the other end of the spiral conveyor belt. In order to ensure that the magnetic and non-magnetic metal scraps are separated more thoroughly, the spiral conveyor belt can be operated forward and reversely for many times so that the magnetic metal scraps are adsorbed by the electromagnetic suction cup 234 as much as possible. During the last forward rotation, the movable baffle 233 on the side away from the gate valve 222 is opened, and the non-magnetic metal scraps are discharged through the corresponding scrap outlet 232 under the transportation of the conveyor belt 231. After the non-magnetic metal scraps are discharged, the baffle 233 on the other side is opened, the electromagnetic suction cup 234 is closed, the magnetic metal scraps fall onto the conveyor belt 231, and the conveyor belt 231 is reversed, and the magnetic metal scraps are discharged from the corresponding scrap outlet 232.

[0038] like Figure 9-12 As shown, further, two waste transfer boxes 24 are respectively located on both sides below the waste transfer device 23, and each waste transfer box 24 is simultaneously connected to the waste outlet 232 on one side of the multiple transport boxes 230. A discharge port 240 is provided on one side wall of the waste transfer box 24, and a second push plate 241 matching the shape of the discharge port 240 is provided in the waste transfer box 24. The second push plate 241 is connected to the second cylinder 243 through a second telescopic rod 242 penetrating the other side wall of the waste transfer box 24. Further, the pressing device 25 includes two pressing boxes 250, which are located outside the discharge port 240 and are connected to the waste transfer boxes 24 one by one. A third cylinder 251 is installed between the two pressing boxes 250, and the output end of the third cylinder 251 is connected to the third push plate 253 inside the pressing box 250 in a one-to-one correspondence through a third telescopic rod 252 that penetrates the side wall of the pressing box 250. Furthermore, a slag discharge port 254 is provided at one end of the long side plate of the pressing box 250 away from the third cylinder 251, and a second gate valve 255 is installed at the slag discharge port 254. A fourth push plate 256, a fourth telescopic rod 257 and a fourth cylinder 258 corresponding to the slag discharge port 254 are also provided at the end of the pressing box 250.

[0039] The second cylinder 243 drives the second telescopic rod 242, and the second telescopic rod 242 pushes the second push plate 241 to push the metal scraps in the scrap transfer box 24 into the compression box 250 through the discharge port 240. At this time, the second push plate 241 is not recovered, but still stays at the discharge port 240, and forms a closed space between it and the compression box 250. At the same time, the third cylinder 251 drives the third telescopic rod 252, and the third telescopic rod 252 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 the compression is completed, the second push plate 241 and the third push plate 253 are recovered, the second gate valve 255 is opened, and the fourth push plate 256 drives the fourth telescopic rod 257 and the fourth cylinder 258 to discharge the compressed metal scraps from the slag discharge port 254 to the scrap box 26.

[0040] like Fig.13 As shown, further, each waste box 26 is connected to the compression box 250 one by one 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.

[0041] Each waste box 26 is connected to 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.

[0042] The entrance of the waste box 26 is provided with a ramp 260. When the metal waste pieces 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 waste pieces in the waste box 26 can be taken out for unified treatment.

[0043] The following is the complete working principle of the present invention: like Figure 1-13 As shown, when the metal cutting device capable of recycling waste chips is used, a suitable cutting device 1 is selected according to specific processing requirements. The tool holder box 12 is located on the right side. A tool holder 120 is arranged in the tool holder box 12 for clamping the tool, and the workpiece clamped on the chuck box 11 is processed by the tool. The workbench 13 is located between the chuck box 11 and the tool holder box 12. A workpiece tray 15 is arranged on the workbench 13 for placing metal workpieces. The cutting rack 14 arranged above the workbench 13 is used to process the workpiece on the workpiece tray 15. The tool holder 120 is moved by a first slide rail 121 arranged on the workbench 13. The workpiece tray 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 can prevent metal waste chips from entering the tool holder box 12.

[0044] 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. 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 through a compressor. When in use, liquid nitrogen is extracted from the outlet valve of the storage bottle, mixed with 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 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).

[0045] When cutting a metal workpiece, the negative pressure fan 215 is started, and a negative pressure area is formed in the negative pressure collection box 212 under the action of the negative pressure fan 215. At the same time, in conjunction with the purge of the air cooling device 16, the cut metal scraps are sucked into the negative pressure collection box 212 through the collection trough 211. When a certain amount of metal scraps are collected in the negative pressure collection box 212 or after a certain period of time, the first cylinder 219 is started, and the first cylinder 219 drives the first telescopic rod 218 to push the first push plate 217, and the first push plate 217 pushes the metal scraps to lift the baffle 216, and the metal scraps then fall into the scrap crushing device 22.

[0046] The metal scraps are broken up in the scrap crushing device 22 for subsequent separation. After the crushing is completed, the gate valve 222 below the crushing area 220 is opened, and the metal scraps fall into the transport box 230. A crushing roller 223 is provided in the crushing area 220, and the crushing roller 223 is connected to a crushing motor 224 outside the scrap crushing device 22. A plurality of crushing pieces 225 are also provided on the crushing roller 223 for stirring and crushing the metal scraps.

[0047] The crushed metal scraps enter the transport box 230 through the gate valve 222. An electromagnetic suction cup 234 is arranged above the rear 2 / 3 of the forward running of the conveyor belt 231 in the transport box 230, and a gate valve 222 (waste scrap crushing device 22) is arranged above the front 1 / 3. When the metal scraps enter the transport box 230, the motor 235 drives the conveyor belt 231, and the conveyor belt 231 transports the metal scraps forward. At this time, the movable baffles 233 at the two scrap outlets 232 are both in a closed state. With the transportation of the spiral conveyor belt (conveyor belt 231), the magnetic metal scraps are adsorbed by the electromagnetic suction cup 234, and the remaining non-magnetic metal scraps are transported to the other end of the spiral conveyor belt. In order to ensure that the magnetic and non-magnetic metal scraps are separated more thoroughly, the spiral conveyor belt can be operated forward and reversely for many times so that the magnetic metal scraps are adsorbed by the electromagnetic suction cup 234 as much as possible. During the last forward rotation, the movable baffle 233 on the side away from the gate valve 222 is opened, and the non-magnetic metal scraps are discharged through the corresponding scrap outlet 232 under the transportation of the conveyor belt 231. After the non-magnetic metal scraps are discharged, the baffle 233 on the other side is opened, the electromagnetic suction cup 234 is closed, the magnetic metal scraps fall onto the conveyor belt 231, and the conveyor belt 231 is reversed, and the magnetic metal scraps are discharged from the corresponding scrap outlet 232.

[0048] 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.

[0049] During compression, the second cylinder 243 drives the second telescopic rod 242, and the second telescopic rod 242 pushes the second push plate 241 to push the metal scraps in the scrap transfer box 24 into the compression box 250 through the discharge port 240. At this time, the second push plate 241 is not recovered, but still stays at the discharge port 240, and forms a closed space between the compression box 250. At the same time, the third cylinder 251 drives the third telescopic rod 252, and the third telescopic rod 252 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, the second push plate 241 and the third push plate 253 are recovered, the second gate valve 255 is opened, and the fourth push plate 256 drives the fourth telescopic rod 257 and the fourth cylinder 258 to discharge the compressed metal scraps from the slag discharge port 254 to the scrap box 26.

[0050] The entrance of the waste box 26 is provided with a ramp 260. When the metal waste pieces 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 waste pieces in the waste box 26 can be taken out for unified treatment.
