[0036] The utility model comprises a cutting knife 33, and the cutting knife 33 is a highly wear-resistant shearing knife.

[0037] When the existing shearing machine for processing scrap steel 7 shears the scrap steel 7, since the scrap steel 7 has a certain ductility, the shearing part of the scrap steel 7 may be dented or uneven, which may have a certain impact on the later processing and bring unnecessary troubles; the shearing machine for processing scrap steel 7 can automatically smooth the cut after the scrap steel 7 is sheared, which can effectively eliminate the dents and unevenness that may occur during the cutting process, so that the scrap steel 7 can be flat after processing; First, the scrap steel 7 to be sheared is placed on the conveyor belt 11, which is an intermittent conveyor belt 11 of the prior art. By adopting such a conveyor belt 11, the conveying of the scrap steel 7 can be stopped when the scrap steel 7 is sheared, so that the scrap steel 7 can stop moving, and the scrap steel 7 can be prevented from sliding during the shearing process, and the scrap steel 7 can also be prevented from deviating during the shearing process; when the scrap steel 7 is conveyed to the bottom of the extrusion block 3, the docking slider 62 at both sides slides on the docking block 6 under the drive of the second hydraulic rod 61, so that there is a certain gap between the docking sliders 62 on both sides, so that the cutting knife 33 can cut the scrap steel 7 normally, prevent the cutting knife 33 from being damaged, and extend the service life of the cutting knife 33. While protecting the cutting knife 33, the scrap steel 7 can also be effectively cut; 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. Through the design of the fixed block 2 and the first slide groove 21, the extrusion block 3 can 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 press the scrap steel 7. 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. The cutting knife 33 is pushed further, so that the cutting knife 33 cuts the scrap steel 7, and the cutting knife 33 slides toward the gap between the two docking slide blocks 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 fixing block 2, and when the extruding block 3 contacts the scrap steel 7, the limiting block 45 between the cutting knife 33 and the toggle plate 4 slides in the third slide groove 32, so that the extruding block 3 will not limit the sliding of the cutting knife 33, so that the cutting knife 33 can complete the cutting action of the scrap steel 7; After the scrap steel 7 is cut by the cutting knife 33, the two docking slide blocks 62 can be docked 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. A flat table surface can be provided for smoothing the cutout 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 does not affect the cut scrap steel 7 during the sliding process of the docking slide block 6, and will not cause the scrap steel 7 to deviate. When the cutting knife 33 slides downward between the two fixing blocks 2, the ratchet 42 and the gear 43 on the toggle plates 4 at both ends of the cutting knife 33 slide in the second slide groove 22, and 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 be in an 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 slide 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 3 will drive the pawl 44 to rotate together, and the pawl 44 will not interfere with the ratchet 42 at this time, so that the gear 43 and the pawl 44 rotate on one side of the ratchet 42, and the gear 43 is in an idling state at this time. At the same time, the length of the rack 23 is just enough for the gear 43 to rotate one circle, and the gear 43 will not rotate too much. Through such a design, the ratchet 42 will not rotate before cutting the scrap steel 7, so that the cutter 33 will not rotate until the scrap steel 7 is cut and the cutter 33 slides upward, and the ratchet 42 will rotate in cooperation with the gear 43 and the pawl 44. When the scrap steel 7 is cut, and the docking slide block 62 is docked under the drive of the second hydraulic rod 61, the first hydraulic rod 37 drives 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 plurality of 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 later. 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. When the cutting knife 33 slides upward, it will drive 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. The reverse rotation of the gear 43 drives the pawl 44 on the gear 43 to rotate together. The gear 43 drives the pawl 44 to reverse. One end of the pawl 44 is provided with a stop block to prevent the pawl 44 from rotating, 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 will drive the dial plate 4 to rotate together. When the dial plate 4 rotates, it will drive 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 swing of the resistance rod 41; as the resistance rod 41 continues to swing, one end of the resistance rod 41 first contacts one end of the smoothing block 5, and after the resistance rod 41 contacts the smoothing block 5, the smoothing block 5 will slide in the fourth slide groove 36, and the sliding of the smoothing block 5 causes the third spring 54 on one side of the smoothing block 5 to deform, and the deformation of the third spring 54 provides power for the subsequent restoration of the smoothing block 5 to its original position, and the sliding of the smoothing block 5 and the cooperation of the docking slider 62 cause one end of the smoothing block 5 to smooth the depression or wrinkles at the cut of the scrap steel 7, so that the cut of the scrap steel 7 can be flat; At the same time, as the resistance rod 41 continues to swing, when one end of the resistance rod 41 contacts the sliding rod 51, a protrusion is provided at the end of the sliding rod 51 that contacts the resistance rod 41. Through such a design, even if the resistance rod 41 slides upward with the cutting knife 33, the resistance rod 41 can contact the sliding rod 51 to the required position, so that the sliding rod 51 slides into the smoothing block 5. Through the design of the fixing plate 58, the sliding rod 51 can slide in the fixing plate 58 to prevent the sliding rod 51 from deviating when sliding. At the same time, the position of the second spring 52 can be restricted. When the sliding rod 51 slides into the smoothing block 5, the second spring 52 will be deformed. Through the deformation of the second spring 52, the sliding rod 51 provides power when it returns to its original position later, so that the sliding rod 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 part of the smoothing wheel 56. Such a design enables the connecting rod 53 to 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 enables 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 cut of the scrap steel 7. The convex arc block 57 has a certain elasticity, and the concave or wrinkled parts of the scrap steel 7 can be smoothed by secondary smoothing on the cut of the scrap steel 7. After the cut of the scrap steel 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 ends, the convex arc block 57 has completed the re-smoothing of the cut of the scrap steel 7, and the abutment rod 41 has also passed the position of the smoothing block 5 and the sliding rod 51, so that the abutment rod 41 no longer abuts the smoothing block 5 and the sliding rod 51. The length of the rack 23 is just enough for the gear 43 to rotate one circle, so that the gear 43 drives the dial 4 and the abutment 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 the initial position, and 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 returns to the initial position, so as to smooth the next cut; 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 conflict 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 incision 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.
