[0031] A conveyor belt 11 for transporting scrap steel 7 is provided on one side of the processing table 1, and a fixed bar 24 is provided between the two fixed blocks 2. A first hydraulic rod 37 is fixedly installed on one side of the fixed bar 24, and the power output end of the first hydraulic rod 37 is fixedly connected to one side of the cutting knife 33.

[0032] A plurality of raised blocks 34 are fixedly connected to both sides of the cutting knife 33 . The raised blocks 34 are slidably connected to the extrusion block 3 . A first spring 35 is provided on one side of each raised block 34 . The first spring 35 is provided inside the extrusion block 3 .

[0033] Both ends of the cutting knife 33 are fixedly connected with a limiting block 45, which is used to be slidably connected to the third slide groove 32. One side of the limiting block 45 is rotatably connected to the toggle plate 4, and one side of the toggle plate 4 is fixedly connected to the interference rod 41. One side of the interference rod 41 is used to interfere with the smoothing block 5 and the sliding rod 51.

[0034] A ratchet 42 is provided on one side of the dial 4 . A gear 43 is rotatably connected to one side of the ratchet 42 . A pawl 44 is rotatably connected to one side of the gear 43 . The pawl 44 is used to abut against the ratchet 42 .

[0035] A pair of first sliding grooves 21 are formed on one side of the fixed block 2 . The first sliding grooves 21 are used for sliding connection with the sliding block 31 .

[0036] A second sliding groove 22 is provided on one side of the fixing block 2 . The second sliding groove 22 is located between the two first sliding grooves 21 . A rack 23 is provided inside the second sliding groove 22 . The rack 23 is used to engage with the gear 43 .

[0037] A docking block 6 is provided on one side of the processing table 1 , and a second hydraulic rod 61 is provided on both sides of the docking block 6 . The power output end of the second hydraulic rod 61 is fixedly connected to a docking slider 62 , and the docking slider 62 is slidably connected to the docking block 6 .

[0038] The docking block 6 is located at one end of the conveyor belt 11 , and the docking block 6 is located below the cutting blade 33 .

[0039] The cutting blade 33 is a highly wear-resistant shearing blade.

[0040] When the existing shearing machine for processing scrap steel 7 shears the scrap steel 7, due to the certain ductility of the scrap steel 7, the sheared part of the scrap steel 7 may be concave or uneven, which may have a certain impact on the subsequent processing and bring unnecessary trouble; the shearing machine for processing scrap steel 7 can automatically smooth the cut part after the scrap steel 7 is sheared, which can effectively eliminate the concave and unevenness that may occur during the cutting process, so that the scrap steel 7 can be flat after processing;

[0041] When the scrap steel 7 is cut, the scrap steel 7 is cut to the limit of 0.05mm and the scrap steel 7 is cut to the limit of 0.05mm.

[0042] Under the action of the first hydraulic rod 37 under the fixing bar 24, the cutting knife 33 is driven to slide downward. The position of the first hydraulic rod 37 can be fixed by the action of the fixing bar 24 to prevent the first hydraulic rod 37 from swinging during operation. At the same time, the design of the fixing bar 24 enables the first hydraulic rod 37 to effectively drive the cutting knife 33. When the cutting knife 33 slides downward, the extrusion block 3 is driven to slide downward together under the action of the protrusion block 34 and the first spring 35, so that the extrusion block 3 can slide downward. The block 31 slides in the first slide groove 21. The design of the fixed block 2 and the first slide groove 21 enables the extrusion block 3 to slide along a predetermined track, so that the extrusion block 3 can be restricted between the two fixed blocks 2, which can effectively prevent the extrusion block 3 from deviating during the downward sliding process. At the same time, the extrusion block 3 can effectively squeeze the scrap steel 7, so that the extrusion block 3 can press the scrap steel 7 tightly. The elastic force of the first spring 35 is also relatively large. At the same time, under the action of multiple first springs 35, the extrusion block 3 can squeeze the scrap steel The scrap steel 7 is tightly pressed against the docking block 6. At the same time, through such a design, before the cutting knife 33 cuts the scrap steel 7, the extrusion block 3 will first firmly fix the position of the scrap steel 7 to prevent the scrap steel 7 from deflecting and sliding when the cutting knife 33 cuts the scrap steel 7. When the position of the scrap steel 7 is fixed, as the first hydraulic rod 37 continues to push the cutting knife 33, the cutting knife 33 slides in the extrusion block 3, and the first spring 35 continues to deform. As the first hydraulic rod 37 The continued pushing of the cutting knife 33 causes the scrap steel 7 to be cut, and the cutting knife 33 slides toward the gap between the two docking sliders 62, so that the scrap steel 7 can be cut by the cutting knife 33; when the cutting knife 33 drives the extruding block 3 to slide downward along the fixed block 2, and when the extruding block 3 comes into contact with the scrap steel 7, the limiting block 45 between the cutting knife 33 and the toggle plate 4 slides in the third chute 32, so that the extruding block 3 will not restrict the sliding of the cutting knife 33, so that the cutting knife 33 can complete the cutting action of the scrap steel 7;

[0043] After the scrap steel 7 is cut by the cutting knife 33, the two docking slide blocks 62 are able to complete docking under the action of the second hydraulic rod 61, so that there is no gap between the two docking slide blocks 62, and a flat table surface can be formed under the scrap steel 7 to prepare for subsequent smoothing. At the same time, the docking slide block 62 has a certain hardness, and will not deform or dent the docking slide block 62 during the smoothing process of the scrap steel 7, and can provide a flat table surface for smoothing the cut portion of the scrap steel 7. Under the action of the second hydraulic rod 61, the docking slide block 62 will not slide or deviate during the smoothing process. At the same time, the design of squeezing the scrap steel 7 onto the docking block 6 by the squeezing block 3 ensures that the docking slide block 62 will not affect the cut scrap steel 7 during the sliding process, and will not cause the scrap steel 7 to deviate.

[0044] When the cutting knife 33 slides downward between the two fixed blocks 2, the ratchet 42 and the gear 43 on the toggle disk 4 at both ends of the cutting knife 33 will slide in the second sliding groove 22. At the same time, a torsion spring that can restore the ratchet 44 to its original position is provided on one side of the ratchet 44. The torsion spring design can drive the ratchet 44 to its initial state, so that the ratchet 44 can cooperate with the ratchet 42 when needed. At the same time, when the cutting knife 33 drives the ratchet 42 and the gear 43 to slide downward in the second sliding groove 22, and when the gear 43 slides to the rack 23, as the gear 43 continues to slide downward, it will cause the gear 43 to rotate, and the gear 4 When the gear 43 rotates, the pawl 44 is driven to rotate together. At this time, the pawl 44 does not interfere with the ratchet 42, so that the gear 43 rotates with the pawl 44 on one side of the ratchet 42. At this time, the gear 43 is in an idling state. At the same time, the length of the rack 23 is just enough for the gear 43 to rotate one circle, so the gear 43 does not rotate too much. Through this design, the ratchet 42 will not rotate before the scrap steel 7 is cut. After the cutting knife 33 completes cutting the scrap steel 7 and when the cutting knife 33 slides upward, the ratchet 42 will rotate in cooperation with the gear 43 and the pawl 44.

[0045] When the scrap steel 7 is cut, and the docking slide 62 is docked again under the drive of the second hydraulic rod 61, the first hydraulic rod 37 will drive the cutting knife 33 to slide upward, so that the cutting knife 33 can be away from the incision of the scrap steel 7. At the same time, under the action of the multiple first springs 35, the squeezing block 3 can still squeeze the scrap steel 7 at this time. At the same time, the elastic force of the first spring 35 is relatively large, so that the squeezing block 3 can effectively limit the position of the scrap steel 7. Through such a design, even if the first hydraulic rod 37 drives the cutting knife 33 to slide upward, the squeezing block 3 can still effectively squeeze the scrap steel 7, so that the incision of the scrap steel 7 can be effectively smoothed subsequently. At the same time, the upward sliding of the cutting knife 33 can also provide a certain space for smoothing the incision of the scrap steel 7.

[0046] When the cutting knife 33 slides upward, it drives the gears 43 at both ends to mesh with the rack 23 in the second sliding groove 22. At this time, the gear 43 reverses, and the reverse rotation of the gear 43 causes the gear 43 to drive the pawl 44 on the gear 43 to rotate together. The gear 43 drives the pawl 44 to reverse, and one end of the pawl 44 is provided with a stop block to prevent the pawl 44 from rotating with it, so that the pawl 44 conflicts with the ratchet teeth of the ratchet wheel 42, so that the ratchet wheel 42 rotates. When the ratchet wheel 42 rotates, it drives the dial plate 4 to rotate together. When the dial plate 4 rotates, it drives the interference rod 41 to swing. At the same time, the interference rod 41 will not contact the sliding block 31, and the sliding The position of the moving block 31 will not limit the swinging of the interference rod 41; as the interference rod 41 continues to swing, one end of the interference rod 41 first interferes with one end of the smoothing block 5. After the interference rod 41 interferes with the smoothing block 5, the smoothing block 5 will slide in the fourth slide groove 36. The sliding of the smoothing block 5 causes the third spring 54 on one side of the smoothing block 5 to be deformed. The deformation of the third spring 54 provides power for the subsequent restoration of the smoothing block 5 to its original position. Through the sliding of the smoothing block 5 and the cooperation of the docking slider 62, one end of the smoothing block 5 smoothes the depression or wrinkles at the cut of the scrap steel 7, so that the cut of the scrap steel 7 can be flat.

[0047] When the sliding rod 51 slides into the smoothing block 5, the second spring 52 is deformed, and the deformation of the second spring 52 provides power for the sliding rod 51 to return to its original position. 51 pushes the connecting rod 53 to move, and at the same time, the movement of the sliding rod 51 causes the smoothing wheel 56 to rotate. The connecting rod 53 is located at the eccentric position of the smoothing wheel 56. Through such a design, the connecting rod 53 can push the smoothing wheel 56 to rotate when sliding. At the same time, a groove 55 is provided on the smoothing block 5. The design of the groove 55 allows the smoothing wheel 56 to drive the convex arc block 57 to rotate together, and the convex arc block 57 can swing in the groove 55, providing a certain space for the swing of the convex arc block 57, so that the convex arc block 57 can swing outside the smoothing block 5, so that the convex arc block 57 can perform secondary smoothing on the incision of the scrap steel 7. The convex arc block 57 has a certain elasticity. Through the secondary smoothing of the incision of the scrap steel 7, the concave or wrinkled parts of the scrap steel 7 can be smoothed.

[0048] When the cut of the scrap steel material 7 is smoothed, as the first hydraulic rod 37 drives the extrusion block 3 to continue to slide upward, when the meshing of the gear 43 and the rack 23 is completed, the convex arc block 57 has completed the smoothing of the cut of the scrap steel material 7 again, and the interference rod 41 has also passed the position of the smoothing block 5 and the sliding rod 51, so that the interference rod 41 no longer interferes with the smoothing block 5 and the sliding rod 51. The design that the length of the rack 23 is just enough for the gear 43 to rotate one circle enables the gear 43 to drive the dial 4 and the interference rod 41 to rotate back to the initial state; at the same time, under the action of the second spring 52, the connecting rod 53 is driven to slide back, so that the smoothing wheel 56 is reversed, so that the smoothing wheel 56 drives the convex arc block 57 to return to its initial position. At the same time, under the action of the third spring 54, the smoothing block 5 slides in the fourth slide groove 36, so that the smoothing block 5 is restored to its initial position, and the next cut is smoothed;

[0049] As the first hydraulic rod 37 drives the cutting knife 33 to continue to slide upward, when the limiting blocks 45 at both ends of the cutting knife 33 slide to one end of the third slide groove 32, the limiting blocks 45 at this time will interfere with the extrusion block 3, so that the cutting knife 33 will drive the extrusion block 3 to slide upward together. As the extrusion block 3 slides upward, the extrusion block 3 releases the extrusion of the scrap steel 7, and the position of the scrap steel 7 can be moved. At this time, the conveyor belt 11 will automatically start to complete the cutting and transport the scrap steel 7 with the smoothed cut to the next processing link. At the same time, the intermittent time of the conveyor belt 11 is just enough for the cutting knife 33 to complete the cutting of the scrap steel 7 and restore the cutting knife 33 to its initial state.

[0050] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0051] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
