Description

Technical Field

[0002] In industrial production, there is often a large amount of metal waste left over. Shearing and recycling metal waste can save costs in industrial production and facilitate the full utilization of metal resources. When shearing metal waste, a waste shearing mechanism is needed to cut the waste. When shearing a larger area of ​​metal waste plate, it is inconvenient to move the metal waste plate due to the large area of ​​the metal waste plate, so it is inconvenient to shear according to the required shearing position, which affects the operator's use of the entire shearing mechanism. At the same time, when shearing thicker metal waste plates, there is a lack of auxiliary structure, and the shearing structure is difficult to cut the thicker metal waste plates, which makes it inconvenient to shear metal waste plates of different thicknesses, thereby affecting the applicability of the metal waste plate and inconvenient to use the shearing mechanism.

The second threaded rod 26 is threadedly connected to the slider 24 to drive the slider 24 and the movable frame 6 to move along the slide groove 25, thereby driving the steel plate to move toward the shearing knife 4 position.

The surface of the metal waste plate is cut by the cutting wheel 20, and the second push plate 23 is driven to move by the extension of the fifth electric push rod 22. The metal waste plate is pushed toward the direction of the shear knife 4 by the second push plate 23, thereby completing the pre-processing of the metal waste plate before shearing.

[0037] In summary, when used as a whole:

[0038] When the shearing position is determined, the scrap metal plate is placed on the moving frame 6, and the second threaded rod 26 is driven to rotate by the second motor 21. The second threaded rod 26 is threadedly connected to the slider 24 to drive the slider 24 and the moving frame 6 to move along the slide groove 25, thereby driving the steel plate to move toward the shear knife 4 position. After reaching the required position, according to the required cutting position of the scrap metal plate, the first electric push rod 9 arranged on the fixed frame 7 is extended to drive the first push plate 12 to move, and the first push plate 12 contacts the side end of the scrap metal plate, and the first threaded rod 11 is driven to rotate by the first motor 14.

The surface of the metal waste plate is cut by the cutting wheel 20, and the second push plate 23 is driven to move by the extension of the fifth electric push rod 22. The second push plate 23 pushes the metal waste plate toward the direction of the shear knife 4, thereby completing the pre-processing of the metal waste plate before shearing.

[0040] When the metal scrap plate is being sheared, the shear knife 4 is driven to rise or fall by the extension or contraction of the hydraulic rod 5 through the rotational connection between the support frame 2 and the shear knife 4, and the rotational connection between the shear knife 4 and the support frame 2, thereby shearing the metal scrap plate through the shear knife 4.
