[0041] The following will be combined with the attached embodiment of the present invention Figure 1-10 , clearly and completely describe the technical solution of the present invention.

[0042] The present invention provides Figure 1-6 The metal stamping die waste recycling and processing system shown in the figure comprises a crusher 2 and a processing device 3 which are sequentially arranged on one side of the stamping die 1, a screw conveyor 1 4 is arranged between the crusher 2 and the stamping die 1, the feeding end of the screw conveyor 1 4 is arranged at the bottom of the stamping die 1, a screw conveyor 2 5 is arranged between the processing device 3 and the crusher 2, and a belt conveyor 6 is arranged at the discharge port of the processing device 3 away from the screw conveyor 2 5. The metal waste falling from the bottom of the stamping die 1 is transported to the crusher 2 by the screw conveyor 1 4 for crushing, and the crushed metal waste is then transported to the processing device 3 by the screw conveyor 2 5 to be compressed into metal waste blocks 7, and finally the metal waste blocks 7 are transported out by the belt conveyor 6, and the personnel then transport the metal waste blocks 7 to the furnace, and the metal waste blocks 7 are put into the furnace for smelting to produce other metal products, so as to realize the recycling and reuse of metal stamping die waste.

[0043] At the same time, during the process of crushing the metal waste by the crusher 2, the stamping oil between the metal waste is in the crushing roller and the metal waste, which has the advantages of reducing the friction between the two and reducing the load on the crushing roller, which helps to extend the service life of the crusher 2.

[0044] In order to prevent the stamping oil between the metal scraps from being melted along with the scraps in the furnace, the present invention designs the processing device 3, such as Figure 3 , Figure 4 and Figure 5 As shown, the processing device 3 includes a device housing 31, the interior of the device housing 31 is divided into a waste compression chamber 32 and an oil recovery chamber 33 distributed up and down by a partition 311, a compression assembly 34 is provided inside the waste compression chamber 32, and the compression assembly 34 includes a pressing block 341 and a bottom plate 342, the pressing block 341 is arranged at the top of the waste compression chamber 32, and the bottom plate 342 is arranged on the top of the partition 311, the pressing block 341 is driven to rise and fall by a hydraulic cylinder 343 fixed to the top of the device housing 31, and compresses the crushed metal waste in the waste compression chamber 32;

[0045] Next, a feeding assembly 35 for receiving the metal waste dropped from the screw conveyor 25 is provided on one side of the device housing 31 near the screw conveyor 25. The feeding assembly 35 includes a fixed pipe 351 fixed to one side of the device housing 31 by a connecting rod. A bellows 352 is fixed to the bottom of the fixed pipe 351. One end of the bellows 352 away from the fixed pipe 351 passes through one side of the device housing 31 and is connected to the waste compression chamber 32. The bellows 352 is away from the fixed pipe 351. 1 is fixed with a movable outer frame plate 353 at one end, the movable outer frame plate 353 is embedded in the inner wall of one side of the device housing 31, and the movable outer frame plate 353 is arranged between the pressing block 341 and the bottom plate 342, and at least one electric push rod 354 for pushing the movable outer frame plate 353 to move is fixed on one side of the device housing 31, and the movable outer frame plate 353 and the discharge end of the bellows 352 can move left and right in the waste compression chamber 32, so that the crushed metal waste can fall evenly into the waste compression chamber 32;

[0046] Moreover, a pressure sensor 313 is fixed on the top of the partition 311, and the pressure sensor 313 is arranged at the bottom of the bottom plate 342. Telescopic rods 312 are respectively fixed between the four corners of the top of the partition 311 and the four corners of the bottom of the bottom plate 342, and springs 310 are wound around the telescopic rods 312.

[0047] The crushed metal waste is conveyed to the fixed pipe 351 by the screw conveyor 25, and the metal waste then falls into the waste compression chamber 32 along the bellows 352. At the same time, the electric push rod 354 pushes the movable outer frame plate 353 to reciprocate left and right in the waste compression chamber 32, so as to drive the discharge end of the bellows 352 to move left and right in the waste compression chamber 32. Then, the metal waste falling from the discharge end of the bellows 352 falls evenly onto the bottom plate 342. Figure 7 As shown;

[0048] When the amount of scrap metal on the bottom plate 342 increases gradually, the scrap metal presses down the bottom plate 342. When the bottom plate 342 contacts the pressure sensor 313, the pressure sensor 313 receives the pressure signal and transmits it to the control machine at the front end of the device housing 31. At this time, the control machine drives the electric push rod 354 to reset, so that the movable outer frame plate 353 is embedded in the inner wall of the device housing 31. The hydraulic cylinder 343 starts to drive the pressing block 341 to descend. The pressing block 341 blocks the discharge end of the bellows 352 to stop the discharge. At the same time, the pressing block 341 and the bottom plate 342 jointly compress the scrap metal, thereby compressing the scrap metal into a scrap metal block 7, as shown in FIG. Figure 8 As shown;

[0049] At the same time, if Figure 3-4As shown, the waste compression chamber 32 and the oil recovery chamber 33 are connected by at least one oil pipe 38 fixed to the rear side of the device shell 31, and a filter screen is fixed at one end of the oil pipe 38 close to the waste compression chamber 32 to block the metal waste. When the metal waste is compressed, the stamping oil between the metal wastes is squeezed out, and the stamping oil flows into the oil recovery chamber 33 through the oil pipe 38. The rear end of the device shell 31 is also fixed with an oil drain pipe 39 connected to the oil recovery chamber 33. The stamping oil in the oil recovery chamber 33 is discharged and recovered, and the stamping oil can be reused after filtering and other treatments, thereby saving costs.

[0050] Stamping oil is not put into the furnace for melting along with the metal waste, which has the advantages of improving the quality of the manufactured metal products, avoiding environmental pollution and reducing the energy consumption of the furnace.

[0051] Then, if Figure 3-4 As shown, a pushing assembly 36 for pushing the metal waste block 7 is provided at the bottom of the unloading assembly 35 on one side of the device housing 31, and the pushing assembly 36 includes a movable push plate 361 embedded in the inner wall of one side of the device housing 31, and the movable push plate 361 is arranged between the bottom plate 342 and the movable outer frame plate 353, and the movable push plate 361 is arranged between the protrusions 344, and an electric cylinder 362 for pushing the movable push plate 361 to move is fixed on one side of the device housing 31, and a discharge port is opened on the other side of the device housing 31, and a sealing cover plate 37 is hinged in the opening, and the electric cylinder 362 drives the movable push plate 361 to move, and the movable push plate 361 pushes the metal waste block 7 out of the device housing 31 through the discharge port, and the belt conveyor 6 is arranged at the discharge port;

[0052] After the compression is completed, the pressing block 341 moves up (at this time, the pressing block 341 still blocks the discharge end of the bellows 352), and the electric cylinder 362 drives the movable push plate 361 to move and push the metal waste block 7, opening the sealing cover plate 37 (the sealing cover plate 37 can be opened manually or designed as an automatic door to achieve automatic opening), and the metal waste block 7 falls onto the belt conveyor 6 through the discharge port and is transported out of the sealing cover plate 37 by the belt conveyor 6.

[0053] In addition, if Figure 3 , 5As shown in Figures 9 and 10, at least one protrusion 344 is fixed on the top of the bottom plate 342, and the bottom of the pressing block 341 is provided with grooves 345 of the same number as the protrusions 344, and the grooves 345 are adapted to the shape of the protrusions 344. After the pressing block 341 and the bottom plate 342 compress the crushed metal waste into the metal waste block 7, at least one protrusion 71 adapted to the shape of the groove 345 is formed on the top of the metal waste block 7, and at least one concave portion 72 adapted to the shape of the protrusion 344 is formed on the bottom of the metal waste block 7. When multiple metal waste blocks 7 are stacked, the protrusion 71 on one metal waste block 7 is inserted into the concave portion 72 of the previous metal waste block 7, so as to facilitate the stacking of multiple metal waste blocks 7, thereby facilitating the transportation of multiple protrusions 71, improving the transportation efficiency, and further improving the overall recycling and processing efficiency.

[0054] Then the hydraulic cylinder 343 drives the pressing block 341 to move upward and reset, opening the discharge end of the bellows 352, and the bellows 352 continues to transport the metal waste into the waste compression chamber 32 for compression.

[0055] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
