The driving assembly 6 can drive the first cutter disc 2 and the second cutter disc 3 to rotate, and then the first cutter disc 2 and the second cutter disc 3 drive the first shearing blade 21 and the second shearing blade 31 to shear the rolled piece 8. In addition, a first cam 22 is provided on the first cutter disc 21, and the first cam 22 cooperates with the second cutter disc 3 to clamp the rolled piece 8, so that the first shearing blade 21 and the second shearing blade 31 shear the rolled piece 8. The second cutter disc 3 is provided with a second cam 32, and the second cam 32 can be used to push the sheared rolled piece 8 into the first conduit 5.
[0043] In the present application, at least one first shearing blade 21 is provided on the first cutter disc 2, and at least one second shearing blade 31 is provided on the second cutter disc 3, thereby forming multiple shearing positions, which can realize operations such as head cutting, tail cutting, segmentation and breaking of the rolled piece 8; the rolled piece 8 to be sheared is adjusted to the positions of the first shearing blade 21 and the second shearing blade 31 by the adjusting component 4, so that the rolled piece 8 can be sheared at different shearing positions; the first cam 22 cooperates with the second cutter disc 3 to clamp the rolled piece 8 for shearing by the first shearing blade 21 and the second shearing blade 31, and the sheared rolled piece 8 is pushed into the first conduit 5 by the second cam 32, that is, the rolled piece 8 is pressed down and lifted up by the first cam 22 and the second cam 32, and the rolled piece 8 is horizontally swung by the adjusting component 4, and the rolled piece 8 is quickly transferred to the first conduit 5 through mutual cooperation, thereby avoiding the current situation of relying solely on the response time of the adjusting component 4 to realize the transfer of the rolled piece 8 and avoiding the occurrence of steel piling.
[0044] For further information, see Figure 7 As shown, one end face of the first conduit 5 facing the adjustment component 4 is L-shaped, and the other end face of the first conduit 5 away from the adjustment component 4 is circular. In this way, the L-shaped end face of the first conduit 5 facilitates the second cam 32 to push the rolled piece 8 into the first conduit 5, thereby improving the passing efficiency of the rolled piece 8 and avoiding the occurrence of steel piling. Of course, in this embodiment, according to actual conditions and specific needs, the end face shape of the first conduit 5 can also be set to other shapes, which is not limited here.
[0045] Preferably, see Figure 8 and Fig. 9 As shown, Figure 8 It is a structural diagram of the shearing process of the rolled piece, where Figure 8 a represents the beginning of cutting, b represents the middle of cutting, c represents the end of cutting, and d represents the end of cutting. Fig. 9 It is a structural diagram of the shearing process of the rolled piece tail, where Fig. 9 Among them, e represents the beginning of cutting off the tail of the rolled piece, f represents the middle of cutting off the tail of the miscellaneous pieces, g represents the end of cutting off the tail of the rolled piece, and h represents the end of cutting off the tail of the rolled piece.
[0046] For further information, see Figure 3 and Figure 5 As shown, the number of the first shearing blades 21 is three, and the three first shearing blades 21 are spaced apart along the circumference of the first cutter disc 2. Specifically, in the present application, the three first shearing blades 21 can be a head cutting shearing blade, a tail cutting shearing blade, and a crushing shearing blade, respectively, so that the head cutting, tail cutting, crushing, and other processing of the rolled piece can be achieved by the three first shearing blades 21, respectively. In addition, the first cam 22 is arranged between the two first shearing blades 21.
[0047] In the present embodiment, this crushing shearing edge is preferably used narrow shearing edge.Certainly, in the present application, also can select different wide and narrow shearing edges according to the size of rolled piece 8.
[0048] In this embodiment, the number of the first shearing blades 21 can also be set to four. When the number of the first shearing blades 21 is three, the shearing time is about 2πR / 3V, where R is the radius of the first cutter disc and V is the speed of the rolled piece. When the number of the first shearing blades 21 is four, the shearing time is about πR / V, which can further reduce the response requirements and is more conducive to increasing the shearing speed. Of course, in this embodiment, the number of the first shearing blades 21 can also be set to five, six, etc., and the number is not limited here.
[0049] For further information, see Figure 3 and Figure 5 As shown, the number of the second shearing blades 31 is three, and the two second shearing blades 31 are spaced apart along the circumference of the second cutter disc 3. Specifically, in the present application, the three second shearing blades 31 can also be respectively set as a head cutting shearing blade, a tail cutting shearing blade, and a crushing shearing blade, so that the head cutting, tail cutting, crushing, etc. of the rolled piece can be achieved by cooperating with the three first shearing blades 21 and the three second shearing blades 31 respectively; in addition, the second cam 32 is arranged between two of the second shearing blades 31.
[0050] In the present application, when the workpiece 8 needs to be head-cut, the adjusting component 4 adjusts the head of the workpiece 8 to the position aligned with the head-cutting shearing blade. At this time, the first cam 22 of the first cutter disc 2 presses the head of the workpiece 8 downward, and the head cutting of the workpiece 8 is completed through the cooperation of the first shearing blade 21 and the second shearing blade 31. Subsequently, the second cam 32 on the second cutter disc 3 pushes the subsequent head of the workpiece 8 up, and the adjusting component 4 adjusts the swing of the workpiece 8 to make it enter the first conduit 5, thereby improving the passing efficiency of the workpiece 8 and effectively avoiding subsequent steel piling accidents.
[0051] For further information, see Figure 4 As shown, the first cam 22 is provided with a first inclined portion 23. By providing the first inclined portion 23, the rolled piece 8 can be guided in accordance with the swinging direction of the adjusting assembly 4.
[0052] Preferably, see Figure 6 As shown, the second cam 32 is provided with a second inclined portion 33 , and the second inclined portion 33 can also be used to guide the rolled piece 8 in coordination with the swinging direction of the adjustment component 4 .
[0053] For further information, see Figure 1As shown, the steel rolling flying shear device further includes a waste barrel 7, which is arranged below the first guide tube 5. In this way, by setting the waste barrel 7, when the first shearing blade 21 and the second shearing blade 31 cut the head, tail, or crush the rolled piece 8, the head or tail cut off at this time will fall into the waste barrel 7, realizing unified collection, reducing the subsequent cleaning process.
[0054] For further information, see Figure 1 and Figure 2 As shown, the adjustment assembly 4 includes a support 41, and a second conduit 42 is provided on the support 41. The second conduit 42 can be passed through by the rolled piece 8. In addition, the adjustment assembly 4 also includes an eccentric wheel assembly 43, and the eccentric wheel assembly 43 is installed on the support 41. The eccentric wheel assembly 43 can drive the second conduit 42 to swing in the horizontal direction, so that the rolled piece 8 can be more accurately aligned with the shearing position. In this embodiment, the horizontal direction is the width direction of the support.
[0055] In the present application, the workpiece 8 is driven by the eccentric wheel assembly 43 to swing horizontally; the workpiece 8 is pressed down and lifted up by the first cam 22 and the second cam 32, thereby realizing the spatial movement of the workpiece 8, so that the sheared workpiece 8 can quickly pass through the first conduit 5 from the second conduit 42, thereby avoiding steel piling accidents.
[0056] In the present application, the eccentric wheel assembly 43 includes a motor and an eccentric wheel, and the second conduit 42 runs through the eccentric wheel, so that the eccentric wheel is driven to rotate by the motor, and the eccentric wheel further drives the second conduit 42 to swing in the horizontal direction.
[0057] For further information, see Figure 1 As shown, the drive assembly 6 includes a first rotating shaft and a second rotating shaft, the first rotating shaft is connected to the first cutter disc 2, the second rotating shaft is connected to the second cutter disc 3, the first rotating shaft is provided with a driving gear, the second rotating shaft is provided with a driven gear, the driving gear is meshed with the driven gear, and the drive assembly 6 also includes a driving motor 61, which can drive the driving gear to rotate. In this way, the driving motor 61 drives the driving gear to rotate, and the driving gear drives the driven gear to rotate, thereby realizing the synchronous rotation of the first cutter disc 2 and the second cutter disc 3. Preferably, the number of teeth of the driving gear and the driven gear is the same. Thereby, the rotation speeds of the first cutter disc 2 and the second cutter disc 3 can be the same. Of course, in this embodiment, according to actual conditions and specific needs, the rotation speeds of the first cutter disc 2 and the second cutter disc 3 can also be set to be different, mainly to realize that the first shearing blade 21 and the second shearing blade 31 meet at a certain point in time to form a shearing position.
[0058] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
