An upper knife seat 21 and a lower knife seat 31 are arranged between the two side frames (left and right frames) of the frame 1 along the X-axis direction. The upper knife seat 21 is located above the lower knife seat 31. The upper knife seat 21 and the lower knife seat 31 can slide relative to the frame 1 in the Z-axis direction. An upper shear blade 22 is arranged below the upper knife seat 21, and an upper shear blade 22 is arranged above the lower knife seat 31. A locking block 41 is also provided on the frame 1. The locking block 41 can slide relative to the frame 1 in the Y-axis direction, and the sliding path of the locking block 41 intersects with the sliding path of the upper knife seat 21. That is to say, the locking block 41 can prevent the upper knife seat 21 from sliding. When working, the upper knife seat 21 slides to the lowest point in the negative direction of the Z-axis. At this time, the upper The position of the knife seat 21 in the Z-axis direction is below the locking block 41. The locking block 41 is moved along the Y-axis direction to the top of the upper knife seat 21, and then the upper knife seat 21 is moved in the positive direction of the Z-axis until it abuts against the locking block 41. The locking block 41 limits the upper knife seat 21 in the Z-axis direction to prevent the upper knife seat 21 from moving upward. At this time, the plate is transported to between the upper shear blade 22 and the lower shear blade 32, and the lower knife seat 31 and the lower shear blade 32 are slid upward to press the plate against the upper shear blade 22 and shear. The upper shear blade 22 and the lower shear blade 32 shear the plate from the upper and lower sides of the plate respectively until the plate is cut and the damaged lead is removed. In this process, the locking block 41 provides support for the upper knife seat 21 to prevent the upper knife seat 21 from moving in the Z-axis direction and affecting the shearing result.
[0027] Specifically, an upper shear seat and a gasket may be provided between the upper knife seat 21 and the upper shear blade 22 to adjust the distance between the upper knife seat 21 and the upper shear blade 22. Similarly, a lower shear seat and a gasket may be provided between the lower knife seat 31 and the lower shear blade 32 to adjust the distance between the lower knife seat 31 and the lower shear blade 32.
[0028] Alternatively, if Figure 1As shown, the plate cutting device also includes a locking seat 42 and a locking cylinder 43, wherein the locking seat 42 is connected to the front side or the rear side of the frame 1, and the locking cylinder 43 is connected to the locking seat 42, and the locking cylinder 43 is drivingly connected to the locking block 41.
[0029] In this embodiment, a locking seat 42 is provided on either side of the frame 1 along the Y-axis direction to provide an installation position for the locking cylinder 43. The locking cylinder 43 can be a hydraulic cylinder, and its fixed end is connected to the locking seat 42. The telescopic end of the locking cylinder 43 is connected to the locking block 41. The telescopic direction of the locking cylinder 43 extends along the front-to-back direction (Y-axis direction), which is convenient for driving the locking block 41 to move along the front-to-back direction.
[0030] Specifically, a locking seat 42, a locking cylinder 43 and a locking block 41 are provided on the two vertical beams of the frame 1 along the X-axis direction. The two locking blocks 41 provide support force for the upper tool seat 21, so that the force on the upper tool seat 21 is more stable.
[0031] Optionally, both left and right side frames of the frame 1 are provided with sliding grooves extending in the vertical direction, and both ends of the upper knife seat 21 and the lower knife seat 31 are embedded in the sliding grooves and slidably connected to the sliding grooves.
[0032] In this embodiment, a slide groove is provided on the opposite surfaces of the two side frames (left and right frames) arranged along the X-axis direction of the frame 1, and the slide groove extends along the Z-axis direction. Both ends of the upper tool seat 21 and the lower tool seat 31 along the X-axis direction are embedded in the slide groove. The slide groove stipulates the sliding direction of the upper tool seat 21 and the lower tool seat 31, so as to facilitate the sliding of the upper tool seat 21 and the lower tool seat 31 along the Z-axis direction.
[0033] Alternatively, if Figure 1 and Figure 2 As shown, the plate cutting device also includes an upper lifting cylinder 23 and a lower lifting cylinder 33, and the upper lifting cylinder 23 and the lower lifting cylinder 33 are respectively connected to the upper frame and the lower frame of the frame 1, the upper lifting cylinder 23 is drivingly connected to the upper knife seat 21, and the lower lifting cylinder 33 is drivingly connected to the lower knife seat 31.
[0034] In this embodiment, an upper lifting cylinder 23 and a lower lifting cylinder 33 are provided as driving structures for the upper tool seat 21 and the lower tool seat 31. The fixed end of the upper lifting cylinder 23 is connected to the upper frame of the frame 1 located in the positive direction of the Z-axis, and the telescopic end of the upper lifting cylinder 23 is connected to the upper tool seat 21. The upper lifting cylinder 23 extends along the Z-axis direction to facilitate driving the upper tool seat 21 to slide along the Z-axis direction. The fixed end of the lower lifting cylinder 33 is connected to the lower frame of the frame 1 located in the negative direction of the Z-axis, and the telescopic end of the lower lifting cylinder 33 is connected to the lower tool seat 31, which can drive the lower tool seat 31 to slide toward the positive direction of the Z-axis.
[0035] Specifically, the lower lifting cylinder 33 is a piston cylinder with a diameter of 480 mm and can provide a shear force of 4300 kN. Compared with a standard cylinder, the piston cylinder can provide a greater driving force.
[0036] Alternatively, if Figure 2 As shown, the upper frame and the lower frame of the frame 1 are both provided with through holes extending in the vertical direction, and the upper lifting cylinder 23 and the lower lifting cylinder 33 are arranged in the through holes.
[0037] In this embodiment, through holes extending in the vertical direction are opened on the upper and lower frames of the frame 1, and the upper lifting cylinder 23 and the lower lifting cylinder 33 are arranged in the through holes, so that the upper lifting cylinder 23 is located directly above the upper knife seat 21, and the lifting cylinder is located directly below the lower knife seat 31, which can directly drive the upper knife seat 21 and the lower knife seat 31 to move toward the plate.
[0038] Alternatively, if Figure 2 As shown, the plate cutting device also includes an arc-surface support head 34, which has a flat surface on the top and an arc surface on the bottom. The telescopic end of the lower lifting cylinder 33 is a curved surface, and the curved surface cooperates and abuts with the arc surface. The plane of the arc-surface support head 34 abuts with the lower knife seat 31.
[0039] In this embodiment, an arc-surface support head 34 is provided between the lower lifting cylinder 33 and the lower knife seat 31, and the arc surface of the arc-surface support head 34 faces downward, and the telescopic end of the lower lifting cylinder 33 is provided with a curved surface with the same curvature as the arc surface, and the plane of the arc-surface support head 34 abuts against the lower surface of the lower knife seat 31. During operation, the curved surface of the telescopic end of the lower lifting cylinder 33 contacts the curved surface of the arc-surface support head 34, driving the arc-surface support head 34 to push the lower knife seat 31 upward. When the angle of the lower knife seat 31 is offset and the two ends of the lower knife seat 31 collide with the sliding grooves on the left and right side frames of the frame 1 during sliding, the arc-surface support head 34 can be offset in angle together with the lower knife seat 31. During this process, the arc surface of the arc-surface support head 34 always remains in abutment with the curved surface of the lower lifting cylinder 33, ensuring that the lower lifting cylinder 33 can drive the lower knife seat 31 to move upward.
[0040] Specifically, a groove matching the plane end of the curved support head 34 is formed at the bottom of the lower tool seat 31 , so that the curved support head 34 can be easily embedded in the groove and move together with the lower tool seat 31 .
[0041] Alternatively, if Figure 1 As shown, the plate cutting device further includes a pressing plate 52 and a pressing cylinder 53 extending in a vertical direction, wherein the pressing cylinder 53 is connected to the upper knife seat 21, and the pressing cylinder 53 is drivingly connected to the pressing plate 52, and the pressing plate 52 is used to press tightly above the plate.
[0042] In this embodiment, a pressure cylinder 53 extending in the vertical direction is provided on the upper knife seat 21, the fixed end of the pressure cylinder 53 is connected to the upper knife seat 21, and the telescopic end is connected to the pressure plate 52. The pressure cylinder 53 can drive the pressure plate 52 to move along the Z-axis direction. When the plate extends between the upper shear blade 22 and the lower shear blade 32, the pressure cylinder 53 drives the pressure plate 52 to move downward until it is pressed above the plate together with the upper shear blade 22, thereby providing support force for the plate and making the plate more stable during the shearing process.
[0043] Alternatively, if Figure 1 As shown, the plate cutting device also includes a connecting block 51, two of the connecting blocks 51 are connected to the front side or the rear side of the upper knife seat 21, and slideways extending in the vertical direction are provided on the opposite surfaces of the two connecting blocks 51, and the left and right ends of the pressure plate 52 are slidably connected in the slideways.
[0044] In this embodiment, two opposite connecting blocks 51 are arranged on one side of the upper tool holder 21 along the Y-axis direction, and slideways extending along the Z-axis direction are opened on the opposite sides of the connecting blocks 51. Both ends of the pressing plate 52 along the X-axis direction are embedded in the slideways, which specifies the sliding direction of the pressing plate 52, making it convenient for the pressure cylinder 53 to drive the pressing plate 52 to slide along the Z-axis direction.
[0045] Alternatively, if Figure 1 As shown, the plate cutting device further comprises a reset cylinder 6 extending in the vertical direction, wherein the reset cylinder 6 is connected to the frame 1 and is drivingly connected to the lower knife seat 31 .
[0046] In this embodiment, a reset cylinder 6 is arranged on the vertical beam of the frame 1 along the X-axis direction, the reset cylinder 6 extends along the Z-axis direction, and a connecting plate extending toward the reset cylinder 6 is arranged at the bottom of the lower tool seat 31, and the connecting plate is connected to the telescopic end of the reset cylinder 6. During shearing, the reset cylinder 6 works together with the lower lifting cylinder 33 to drive the lower tool seat 31 to move upward. After the shearing is completed, the lower lifting cylinder 33 is shortened, and the arc support head 34 is separated from the lower tool seat 31. The lower lifting cylinder 33 cannot drive the lower tool seat 31 to move downward. At this time, the reset cylinder 6 is shortened to drive the lower tool seat 31 to move downward.
[0047] Specifically, the vertical beams on both sides of the frame 1 along the X-axis direction are provided with reset cylinders 6, so that the lower knife seat 31 is subjected to force more evenly and will not deviate when moving downward.
[0048] Alternatively, if Figure 3 As shown, the upper shear blade 22 has a herringbone shape, and the lower shear blade 32 has a straight shape. The upper shear blade 22 and the lower shear blade 32 are staggered in the front-to-back direction of the frame 1 .
[0049] In this embodiment, by setting the blade head of the upper shear blade 22 to a herringbone shape and setting the blade edge of the lower shear blade 32 to a straight line shape, when the upper shear blade 22 and the lower shear blade 32 contact the plate at the same time, the blade edge of the upper shear blade 22 and the blade edge of the lower shear blade 32 are set at an angle and staggered along the Y-axis direction, the plate can be sheared like a pair of scissors, making it easy to divide the plate into two halves.
[0050] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
