Description

Technical Field

[0001] This utility model relates to the field of waste recycling technology, and more specifically, to a waste recycling device for metal mold stamping production. Background Technology

[0002] In modern manufacturing industries such as hardware products, auto parts, and home appliance casings, metal sheet stamping is a very common and efficient processing method. This process relies on the mold to separate or plastically deform the sheet under the huge pressure of the stamping equipment, thereby obtaining parts of the required shape. In the separation process such as blanking, a large amount of scrap and waste will inevitably be generated. However, the waste recycled by traditional waste recycling devices often has residual impurities and occupies a large space.

[0003] On the one hand, during the stamping process, in order to lubricate the mold, reduce friction, prevent workpiece scratches, and cool the mold and workpiece, cutting oil, lubricating oil, or emulsions are usually used continuously as cooling and lubricating media. These liquids inevitably adhere to the surface of the sheet metal in large quantities and are carried into the scrap area during the stamping process. These residual impurities not only pollute the scrap itself, causing it to produce odors and leaks during subsequent storage, transportation, and smelting recycling, but also cause secondary pollution.

[0004] On the other hand, the waste generated by stamping, especially strip-shaped, sheet-shaped, or porous waste, is usually loose and fluffy. When it is simply collected into bins, hoppers, or carts, there are a lot of voids inside, and the bulk density is very low. This means that the same weight of waste needs to occupy several times the volume of the compacted state. This low-density, loose state causes the waste to occupy valuable production space when it is temporarily stored in the workshop. More importantly, when it is loaded onto trucks and transported to the recycling plant, the loading space utilization rate of the transport vehicles is extremely low.

[0005] Therefore, existing waste recycling facilities need improvement in terms of waste residue treatment and the space occupied by waste. Utility Model Content

The piston rods of the two sets of hydraulic cylinders 103 are respectively connected to compression blocks 104 for applying pressure to the waste material and compressing it for transportation. A hot air blower 105 is installed on one side wall of the compression box 100 to deliver hot air into the box to dry the washed waste material. On the opposite side of the hot air blower 105, a feeding trough 106 is provided for receiving waste material to be processed. The bottom of the cleaning box 101 is supported by a support frame 107. The top opening of the waste tank 101 is equipped with a feeding hopper 108 for easy waste material input. The top of the waste removal tank 101 is equipped with multiple sets of high-pressure nozzles 109 for spraying and cleaning oil, coolant and other impurities on the waste material. One side of the waste removal tank 101 is equipped with an electric telescopic rod 110 for driving the push plate 114 to push the waste material out of the discharge trough 111. On the other side opposite to the electric telescopic rod 110, there is a discharge trough 111 for the cleaned waste material to enter the feeding trough 106. Inside the waste removal tank 101, a horizontal placement plate 112 is installed to support the waste material. A filter screen 113 is installed below the placement plate 112 to filter out fine waste residue in the wastewater. The end of the electric telescopic rod 110 is connected to the push plate 114.

[0029] The compression chamber 100 has an opening at its top, through which a top cover 115 is secured. A mounting bracket 102 is detachably connected to the top surface of the top cover 115 via bolts. Two sets of hydraulic cylinders 103 are fixedly mounted on the bottom frame of the mounting bracket 102. The hydraulic cylinders 103 provide power to the two sets of compression blocks 104, compressing the waste material for transport. The top center of each of the two sets of compression blocks 104 is rigidly connected to the piston rod ends of the two sets of hydraulic cylinders 103, ensuring effective pressure transmission.
