[0004] The existing simple gantry metal cold shearing machine generally does not have preset metal waste horizontal compression and vertical pre-compression function setting, so that the metal waste is often loose and thrown lightly, the bulk density of the raw material is low, the same shearing stroke greatly reduces the sheared metal waste, and the metal raw material shearing efficiency of the metal cold shearing machine is low. At the same time, due to the lack of sizing mechanism, the length of the finished product after shearing is not uniform, and the finished product is not convenient to feed into the electric furnace for smelting.

[0036] Please refer to Figures 1-5 A cold shearing machine compression shearing device is provided for the embodiment, wherein the cold shearing machine compression shearing device comprises:

[0037] The feeding chute 1 has oppositely arranged upstream end and downstream end, and the feeding chute 1 is used for accommodating metal scrap;

[0038] The compression mechanism 2 comprises a horizontal compression part 21, a horizontal compression cylinder 22, a vertical compression part 23 and a vertical compression cylinder 24. The horizontal compression part 21 is arranged at the downstream end of the feeding chute 1, and is connected with the output end of the horizontal compression cylinder 22. The horizontal compression cylinder 22 is used to drive the horizontal compression part 21 to extrude the metal waste along the horizontal direction. The vertical compression part 23 is arranged at the top of the horizontal compression part 21, and is connected with the output end of the vertical compression cylinder 24. The vertical compression cylinder 24 is used to drive the vertical compression part 23 to extrude the metal waste along the vertical direction.

[0039] The shearing mechanism 3 comprises a main shear blade 31 and a shearing cylinder 32. The main shear blade 31 is arranged at the downstream end of the vertical compression part 23, and is connected with the output end of the shearing cylinder 32. The bottom of the main shear blade 31 is arranged towards the discharge port at the most downstream end of the feeding chute 1. The shearing cylinder 32 is used to drive the main shear blade 31 to cut the metal waste into the discharge port.

[0040] The bottom of the vertical compression part 23 is arranged in a stepped shape, and the height of the stepped shape decreases from the upstream end to the downstream end.

[0041] In use, the operator only needs to throw the metal waste from the open position at the upstream end of the feeding chute 1, so that the metal waste falls into the feeding chute 1 and pushes it to the downstream end. When the metal waste passes through the position of the horizontal compression part 21 of the compression mechanism 2, the horizontal compression part 21 runs under the drive of the horizontal compression cylinder 22. The horizontal compression part 21 extrudes the metal waste at this position along the horizontal direction of the feeding chute 1, so that the metal waste is deformed in the horizontal direction and the volume is reduced. Then, similarly, the vertical compression part 23 is driven by the vertical compression cylinder 24 to extrude the metal waste at this position along the vertical direction of the feeding chute 1, so that the metal waste is deformed in the vertical direction, and the metal waste further forms a block with higher density. Then, the compression mechanism 2 returns. After the high-density metal waste after compression moves to a certain position downstream, the shearing cylinder 32 of the shearing mechanism 3 drives the main shear blade 31 to fall and cut off the metal waste into the discharge port. In the steps, the vertical compression part 23 is arranged in a stepped structure, so that the metal waste can be pre-pressed once, and then pressed in the vertical direction again before being processed by the shearing mechanism 3.

[0042] In the above process, the metal waste is compressed multiple times by the horizontal compression part 21 and the vertical compression part 23 to minimize the volume, thereby improving the shearing density of the embodiment. It is worth noting that the stepped part of the vertical compression part 23 can realize one-time pre-pressing, thereby further improving the actual compression density of the metal waste.

[0043] Further, the bottom edge of the main shear blade 31 is matched with the edge position of the most downstream end of the feed chute 1, that is, in this embodiment, the bottom of the main shear blade 31 is actually combined with the edge position of the most downstream end of the feed chute 1 into a scissor shape, so that the bulk metal scrap is completely cut off under the action of the two.

[0044] Further, the feed chute 1 is inclined downward from the upstream end to the downstream end to form a slope for the sliding of the metal scrap, and specifically, by means of the slope structure with the high upstream and the low downstream, the metal scrap placed in the feed chute 1 can be scattered in the downstream end direction under the guidance of the slope, and the slope shape can place more materials.

[0045] Further, the cutting edge of the main shear blade 31 for shearing the metal scrap is arranged in an inverted V shape, and specifically, the inverted V shape structure has a longer shearing line and can more sharply cut off the metal scrap. Figure 5 The structure has a longer shearing line and can more sharply cut off the metal scrap.

[0046] Further, referring to Figure 1 and Figure 6 , the cold shearing machine compression shearing device further comprises a sizing plate 4 arranged above the discharge port downstream of the shearing mechanism 3, and the sizing plate 4 is used to abut against the metal scrap at the downstream end before the shearing mechanism 3 shears the metal scrap. Specifically, in this embodiment, the sizing plate 4 and the feed chute 1 are fixed on the same rack, and by adjusting the distance of the sizing plate 4 relative to the feed chute 1, the length of the preset metal scrap block can be set.

[0047] Further, the stepped shape of the vertical compression part 23 is arranged in two steps, and the two steps are equal in width from the upstream end to the downstream end, that is, in the process of moving the metal scrap to the downstream end, the two steps of the vertical compression part 23 can uniformly compress the metal scrap, and the consistency of the product density is better.

[0048] The above disclosed content is only the preferred feasible embodiment of the utility model, and does not limit the patent application range of the utility model, so that any equivalent technical change made by applying the contents of the utility model specification and drawings is included in the patent application range of the utility model.

[0049] Each embodiment in the specification is described in a progressive manner, and the same or similar parts between each embodiment can be referred to each other, and each embodiment mainly describes the difference from other embodiments.

[0050] Although the present application is described through embodiments, those skilled in the art know that the present application has many modifications and changes without departing from the spirit of the present application, and it is hoped that the attached embodiments include these modifications and changes without departing from the present application.
