[0030] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention.

[0031] like Figure 1-5 As shown, a metal shearing device comprises:

[0032] A support frame 1, wherein a bottom plate 11 is provided on the support frame 1;

[0033] A shearing unit 3 is provided on the support frame 1. The shearing unit 3 includes a cylinder 323 and a blade 31 provided at the output end of the cylinder 323. The blade 31 slides on the support frame 1.

[0034] The clamping unit 2 is provided on the bottom plate 11 and includes a clamping block 22 and a slider 25 provided on the clamping block 22. The clamping blocks 22 are symmetrically slidably provided on the bottom plate 11, and a clamping channel is formed between the two clamping blocks 22.

[0035] A motor 24 is provided at one end of the slider 25 , and a turntable 28 cooperating with the motor 24 is provided at the other end thereof. A push wheel 26 facing the clamping channel is provided at an eccentric position of the turntable 28 .

[0036] Specifically, the support frame 1 is composed of two side plates and a horizontal bottom plate 11. The clamping unit 2 is fixed to the bottom plate 11 and is used to clamp or push the metal material. The shearing unit 3 is located above the bottom plate 11 and is connected to the support frame 1. The metal material is sheared by the blade 31. When the blade 31 slides in the vertical direction, it will fit with one side wall of the bottom plate 11. The motor model is: MHMF042L1U2M2, and the cylinder model is: SCLB100x250. When the metal material needs to be sheared, the metal material is placed on the bottom plate 11. By moving the two clamping units, the metal material is sheared. The block 22 slides on the bottom plate 11 until the push wheel 26 contacts the metal material and applies a certain extrusion pressure to the metal material through the push wheel 26. The cylinder 323 then controls the blade 31 to slide downward in the vertical direction to shear the metal material. After shearing is completed, the motor 24 controls the turntable 28 to rotate. At this time, the push wheel 26 will push the metal material to slide on the bottom plate 11, so that the cutting part extends, and then the shearing operation is performed through the shearing unit 3. The above operation is repeated to make the size of the metal blocks after shearing the metal material more consistent, so as to facilitate the efficiency of subsequent dissolution and recovery.

[0037] As an embodiment further provided by the present invention, a first slide groove 110 and a second slide groove 111 are sequentially provided on the base plate 11, the slider 25 slides on the second slide groove 111, and a guide block 232 is slidingly provided in the first slide groove 110 and engaged with the clamping block 22, a support block 23 is provided on the base plate 11, and a rotating rod 233 is rotatably connected to the support block 23, the rotating rod 233 is threadedly connected to the guide block 232, and the guide block 232 is fixed to the clamping block 22 by a bolt 223, the first slide groove 110 plays the role of a guide limit, and the second slide groove 111 is provided with a rotating rod 233 to control the two guide blocks 232 to slide relative to or toward each other on the base plate 11 through the threaded groove, that is, to control the spacing between the two clamping blocks 22 so that the device can clamp metal materials of different sizes.

[0038] As an embodiment further provided by the present invention, a rotating wheel 231 is provided on the rotating rod 233, and grooves are provided on the rotating wheel 231 along a circumferential array. The rotating wheel 231 can be replaced with a dual-axis motor to control the rotation of the rotating rod 233 through the dual-axis motor. The grooves increase the friction between the hand and the rotating wheel 231, and the rotating rod 233 is rotated to make the two guide blocks 232 slide relative to or toward each other.

[0039] As an embodiment further provided by the present invention, a limiting groove 222 is provided on the clamping block 22, and a limiting plate 221 is slidingly arranged in the limiting groove 222. When shearing a metal plate or a long metal strip, the limiting plate 221 can be pushed to slide in the limiting groove 222, so that the limiting plate 221 limits the metal material, thereby improving the fixing effect when shearing the metal material.

[0040] As an embodiment further provided by the present invention, a square groove 281 is provided on the turntable 28, and a locking column 27 cooperating with the push wheel 26 is slidingly provided in the square groove 281. The locking column 27 can make the push wheel 26 slide on the square groove 281, that is, the eccentric position of the push wheel 26 relative to the turntable 28 is controlled to increase or decrease the extrusion force of the push wheel 26 relative to the metal material.

[0041] As a further embodiment provided by the present invention, a rubber sleeve 261 is clamped on the push wheel 26, and a protrusion is provided on the outer wall of the rubber sleeve 261. When the rubber sleeve 261 contacts the metal material, the protrusion improves the fitting effect of the metal material.

[0042] As an embodiment further provided by the present invention, the shearing unit 3 also includes a top plate 32 arranged on the support frame 1, the cylinder 323 is arranged on the top plate 32, and the output end of the cylinder 323 is provided with a slide plate 33 located on the support frame 1, and the blade 31 is clamped on the slide plate 33, and a triangular support member 321 is provided between the top plate 32 and the support frame 1. The triangular support member 1 is used to improve the connection and fixing effect between the top plate 32 and the support frame 1. At the same time, a guide plate 322 is provided on the top plate 32, and the output shaft of the cylinder 323 slides from the axis center of the guide plate 322, thereby improving the support effect on the cylinder 323.

[0043] As an embodiment further provided by the present invention, a bending plate 34 is provided on the slide plate 33, and a pressing block 30 is provided between the bending plate 34 and the slide plate 33, and a guide rod 301 is provided on the pressing block 30 that cooperates with the bending plate 34, and a screw 302 is threadedly connected to the bending plate 34, and one end of the screw 302 is provided with a spring 303 that cooperates with the pressing block 30, and one end of the pressing block 30 is provided with triangular grooves in a linear array, and the triangular grooves improve the clamping effect of the pressing block 30 and the metal material. When the slide plate 33 is located on the support frame 1 and slides vertically downward, the pressing block 30 will contact the metal material earlier than the blade 31. At this time, the pressing block 30 will be located in the bending plate 34 and the retracted extrusion spring 303 is compressed. The elastic force of the compression spring 303 pushes onto the pressing block 30, thereby clamping the metal material.

[0044] As an embodiment further provided by the present invention, an inclined plate 5 is provided on the support frame 1, and the inclined plate 5 is rotatably connected to the base plate 11. One end of the inclined plate 5 is located directly below the blade 31. After the blade 31 completes shearing, the cut portion of the metal material will fall onto the inclined plate 5 and slide along the inclined plate 5 for collection.

[0045] As a further embodiment provided by the present invention, a support frame 4 is provided on the support frame 1. The support frame 4 has an accommodating cavity. A weight block can be placed in the accommodating cavity to improve the stability of the device during processing and operation.

[0046] Working principle: First, the metal material is placed on the base plate 11, and the rotating rod 233 is rotated according to the size of the metal material. The two clamping blocks 22 are controlled by the guide block 232 to slide relative to or toward each other on the base plate 11 until the rubber sleeve 261 on the push wheel 26 contacts the metal material, and the push wheel 26 gives the metal material a certain clamping effect. The slide plate 33 is then controlled by the cylinder 323 to slide on the support frame 1. At this time, the pressing plate contacts the metal material in advance, and under the elastic action of the spring 303, a certain pre-compression fixing effect is given to the metal material. Then the blade 31 contacts the metal material to complete the shearing operation, and the cylinder 323 retracts. The motor 24 controls the rotation of the turntable 28. The turntable 28 is linked to the push wheel 26 to rotate to make the metal material slide on the base plate 11, and the cut end of the metal material is extended, and then the shearing operation of the shearing unit 3 is performed, so that the size of the metal material stretched out each time is more consistent, reducing the phenomenon of manual hand-held pushing of the metal material, and at the same time improving the subsequent metal material dissolution and recovery efficiency.
