[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0021] like Figure 1-9 As shown, a high-performance CNC steel plate flattening device includes a flattening machine 1 and a cutting mechanism 2 arranged at the discharge port of the flattening machine 1, and also includes a pre-rolling mechanism 3 arranged at the feed port of the flattening machine 1, the pre-rolling mechanism 3 includes a third supporting roller 31 symmetrically rotated along the feed port, the third supporting roller 31 is respectively provided with a pre-pressing head 32 and a matching block 33 moving along the center line, two groups of pre-pressing heads 32 are coupled and rotated with the two third supporting rollers 31 to respectively cooperate with the two groups of matching blocks 33 and roll out convex points on the steel plate 10.

[0022] Specifically, the cutting mechanism 2 includes a first supporting roller 21 and a second supporting roller 22 arranged at the discharge port of the calendering machine 1. The first supporting roller 21 is provided with a cutting blade 211 for continuously cutting the steel plate 10. The second supporting roller 22 is provided with a coupling groove 221 corresponding to the cutting blade 211 to continuously cut the steel plate 10. The two third supporting rollers 31 are both provided with gears 311 so that the two third supporting rollers 31 are coupled and support the steel plate 10. The pre-pressing head 32 and the matching block 33 are on the same center line (with Figure 7 , Figure 8For reference), when the leveling machine 1 is started, the steel plate 10 enters the leveling machine 1 by the rotation of the two first supporting rollers 21. At this time, as the first supporting rollers 21 rotate, the pre-pressing head 32 on one of the third supporting rollers 31 will roll the steel plate 10 as it rotates, and cooperate with the matching block 33 on the other third supporting roller 31 to roll out convex points. As the first supporting roller 21 continues to rotate, the pre-pressing heads 32 on the two first supporting rollers 21 alternately roll out convex points, and then the steel plate 10 enters the leveling machine 1 for leveling. During leveling, the convex points are slightly flattened to increase metal fatigue at this location and reduce strength. After leveling, it is cut by the cutting blade 211 on the first supporting roller 21 to reduce the pressure of the cutting blade 211.

[0023] Furthermore, both the feed port and the discharge port of the leveling machine 1 are provided with pre-supporting plates 14 , and the pre-supporting plates 14 are used to limit the steel plate 10 to remain stable before entering or moving out of the leveling machine 1 .

[0024] The flattening machine 1 is of prior art, and includes a base 11 and an upper frame 12. Flattening rollers 13 are arranged in a linear array on the base 11 and the upper frame 12. The two groups of flattening rollers 13 are staggered. The curled steel plate 10 is flattened by the two groups of flattening rollers 13. The first supporting roller 21, the second supporting roller 22 and the third supporting roller 31 are all driven to rotate by a motor.

[0025] In the above technical scheme, before the curled steel plate 10 enters the leveling machine 1, it is pre-fixed by the third supporting roller 31. While being fixed, the pre-pressing head 32 cooperates with the matching block 33 to roll out convex points on the steel plate 10, and the position of the convex points moves with the steel plate 10 to form a dotted line. Then, the steel plate 10 is leveled by the leveling machine 1 and then cut along the dotted line by the subsequent cutting mechanism 2. After being leveled, the steel plate 10 at the convex point will be deformed and metal fatigue will be generated, which will reduce the strength at this point and facilitate cutting by the cutting blade 211 in the cutting mechanism 2 to protect the slice.

[0026] As an embodiment provided by the present invention, a first slide groove 312 is provided on the third supporting roller 31, and the pre-pressing head 32 and the matching block 33 are slidably connected at both ends of the first slide groove 312, and the pre-pressing head 32 is assembled at the following two stations: First station: the pre-pressing head 32 rotates with the third supporting roller 31 and tilts with the steel plate 10, and rolls out convex points; Second station: the pre-pressing head 32 rotates with the third supporting roller 31 to be perpendicular to the steel plate 10 to retract the first sliding groove 312 .

[0027] Specifically, an arc-shaped pre-pressing blade 321 is provided on the pre-pressing head 32, and a convex point is pressed out by the pre-pressing blade 321. The side of the pre-pressing head 32 is a vertical plane, and it slides in close contact with the first slide groove 312. When the two third supporting rollers 31 are coupled and rotated, the pre-pressing head 32 is first in a state of extending out of the first slide groove 312. The pre-pressing head 32 is tilted and contacts the steel plate 10 to deform it. At this time, the vertical plane is in close contact with the first slide groove 312 to be subjected to force, which is the first work station. As the third supporting roller 31 continues to rotate, the pre-pressing head 32 is embedded in the corresponding matching block 33, and gradually becomes perpendicular to the steel plate 10. The pre-pressing head 32 will slide and retract along the first slide groove 312, stop exerting force on the steel plate 10, so as to reduce the deformation amplitude of the convex point, and at the same time reduce the pressure of the pre-pressing blade 321 to protect it.

[0028] When in use, the steel plate 10 enters the flattening machine 1 along the rotation of the first supporting roller 21. As the first supporting roller 21 rotates, the pre-pressing head 32 will tilt and be restricted by the first slide groove 312 to roll the steel plate 10 and cooperate with the matching block 33 to roll out the convex points until the pre-pressing head 32 is perpendicular to the steel plate 10, completing the rolling step, and then the steel plate 10 enters the flattening machine 1 to flatten the convex points slightly, and is moved out of the flattening machine 1 to be cut by the cutting blade 211.

[0029] As an embodiment provided by the present invention, a double arc convex head 313 is symmetrically opened at the first end of the first slide groove 312, and the side wall of the pre-pressing head 32 slides along the double arc convex head 313; An elastic support block 34 is provided between the pre-pressing head 32 and the anastomosis block 33 . The pre-pressing head 32 is driven to compress the elastic support block 34 and slide along the elastic support block 34 .

[0030] Specifically, the first end of the first slide groove 312 (the first end is the end where the pre-pressing head 32 is located) is symmetrically provided with a double arc convex head 313, and the double arc convex head 313 includes two connected arc convex heads, and the arc convex heads slide in accordance with the vertical plane of the pre-pressing head 32. The two sides of the elastic support block 34 are arc deformation parts 341 made of elastic metal, which can be deformed and provide support. When the arc-shaped pre-pressing blade 321 on the pre-pressing head 32 rolls out a convex point, the pre-pressing head 32 The pre-pressing head 32 will be subjected to pressure, causing it to slide along the double arc convex head 313 and push against the elastic support block 34 to deform. When the pressure is too great, causing the elastic support block 34 to increase in amplitude, the pre-pressing head 32 will move along the double arc convex head 313 until the arc-shaped pre-pressing blade 321 reaches a convex head. The limiting effect of the convex head disappears, allowing the pre-pressing head 32 to flip along a convex point to share the pressure on the pre-pressing blade 321, thereby relieving the force and protecting the pre-pressing blade 321 to prevent it from collapsing.

[0031] When in use, the steel plate 10 enters the flattening machine 1 along the rotation of the first supporting roller 21. As the first supporting roller 21 rotates, the pre-pressing head 32 will tilt and be restricted by the first slide groove 312 to roll the steel plate 10 and cooperate with the matching block 33 to roll out the convex point until the pre-pressing head 32 is perpendicular to the steel plate 10, completing the rolling point step. During this period, when the pressure of the pre-pressing blade 321 is too large, the elastic support block 34 is deformed and compressed to unload the force on the pre-pressing blade 321, and then the steel plate 10 enters the flattening machine 1 to flatten the convex point slightly, and is moved out of the flattening machine 1 to be cut by the cutting blade 211.

[0032] As an embodiment provided by the present invention, a connecting block 35 is provided on the elastic support block 34 , the pre-pressing head 32 is slidably connected to the connecting block 35 , and a first movable groove 314 for the pre-pressing head 32 to slide is provided on the first sliding groove 312 .

[0033] Specifically, a second slide groove 351 is provided on the connecting block 35, and a sliding portion 322 is provided on the pre-pressing head 32. The sliding portion 322 is slidably connected to the second slide groove 351. The second slide groove 351 can allow the pre-pressing head 32 to slide and unload force when the pre-pressing head 32 is subjected to pressure, and the first movable groove 314 provides a sliding stroke to reduce the deformation degree of the elastic support block 34, thereby preventing the elastic support block 34 from being damaged due to excessive deformation caused by the pulling of the pre-pressing head 32 sliding and tilting.

[0034] During use, the steel plate 10 enters the flattening machine 1 along the rotation of the first supporting roller 21. As the first supporting roller 21 rotates, the pre-pressing head 32 will tilt and be restricted by the first slide groove 312 to roll the steel plate 10 and cooperate with the matching block 33 to roll out a convex point until the pre-pressing head 32 is perpendicular to the steel plate 10, completing the rolling point step. During this period, when the pressure of the pre-pressing blade 321 is too large, the elastic support block 34 is deformed and compressed. At this time, the pre-pressing head 32 can flip along a convex point and slide along the second slide groove 351 to unload the pre-pressing blade 321. Then the steel plate 10 enters the flattening machine 1 to flatten the convex point slightly, and is moved out of the flattening machine 1 to be cut by the cutting blade 211.

[0035] As an embodiment provided by the present invention, the outer layer of the third supporting roller 31 is provided with a locking sleeve 41 , and the locking sleeve 41 is provided with elastic inclined plates 43 corresponding to the pre-pressing head 32 in a circumferential array.

[0036] Specifically, the matching block 33 is always slidably connected in the first slide groove 312 and cannot extend out of the first slide groove 312. A plurality of elastic inclined plates 43 are arranged on the locking sleeve 41. When the matching block 33 on one of the third supporting rollers 31 is directed toward another third supporting roller 31, the pre-pressing head 32 on one of the third supporting rollers 31 will push against the elastic inclined plate 43 as it rotates. The elastic inclined plate 43 is pushed and bent by the pre-pressing head 32 to give pressure to the pre-pressing head 32, so that the elastic support block 34 is deformed, the supporting force for the matching block 33 is increased, and the formation of the protrusion is assisted. When the matching block 33 is directed toward the elastic inclined plate 43, the elastic inclined plate 43 does not work to ensure that the elastic support block 34 has a large stroke when the pre-pressing head 32 contacts the steel plate 10, so as to protect the pre-pressing head 32.

[0037] During use, the steel plate 10 enters the flattening machine 1 along the rotation of the first supporting roller 21. At this time, the pre-pressing head 32 facing the locking sleeve 41 will compress the elastic support block 34 to deform, and the matching block 33 facing the locking sleeve 41 will not exert force on the elastic support block 34. As the first supporting roller 21 rotates, the pre-pressing head 32 will tilt and be restricted by the first slide groove 312 to roll the steel plate 10 and cooperate with the matching block 33 to roll out a convex point until the pre-pressing head 32 is perpendicular to the steel plate 10 to complete the point rolling step. During this period, when the pressure of the pre-pressing blade 321 is too large, the elastic support block 34 is deformed and compressed. At this time, the pre-pressing head 32 can flip along a convex point and slide along the second slide groove 351 to unload the pre-pressing blade 321. Then the steel plate 10 enters the flattening machine 1 to flatten the convex point slightly, and is moved out of the flattening machine 1 to be cut by the cutting blade 211.

[0038] As an embodiment provided by the present invention, an elastic support column 342 is provided on the elastic support block 34, and an insertion rod 352 is provided on the connecting block 35. The elastic support block 34 is deformed under pressure so that the insertion rod 352 moves and is inserted into the support groove 343 opened on the elastic support column 342.

[0039] Specifically, the elastic support column 342 is arranged on the diagonal line of the elastic support block 34, and the insertion rod 352 on the connecting block 35 passes through the elastic support block 34 and faces the support groove 343. When the elastic support block 34 is compressed and deformed, the connecting block 35 will move with the deformation to insert the insertion rod 352 into the support groove 343. After the insertion rod 352 is inserted into the support groove 343, the deformation amplitude of the elastic support block 34 is limited, and the force required for the deformation of the elastic support column 342 is increased to increase the supporting capacity, so as to avoid the situation where the pre-pressing head 32 completely passes over the double arc convex head 313 and is stuck in the first movable groove 314.

[0040] When in use, the steel plate 10 enters the flattening machine 1 along the rotation of the first supporting roller 21. At this time, the pre-pressing head 32 facing the locking sleeve 41 will compress the elastic support block 34 to deform, and the matching block 33 facing the locking sleeve 41 will not exert force on the elastic support block 34. As the first supporting roller 21 rotates, the pre-pressing head 32 will tilt and be restricted by the first slide groove 312 to roll the steel plate 10 and cooperate with the matching block 33 to roll out a convex point until the pre-pressing head 32 is perpendicular to the steel plate 10, completing the rolling step. During this period, when the pressure of the pre-pressing blade 321 is too large, the elastic support block 34 is deformed and compressed. At this time, the pre-pressing head 32 can flip along a convex point and slide along the second slide groove 351 to unload the force on the pre-pressing blade 321. When the deformation amplitude of the elastic support block 34 is too large, the insertion rod 352 will be inserted into the support groove 343 to limit the deformation amplitude of the elastic support block 34, and then the steel plate 10 enters the flattening machine 1 to flatten the convex point slightly, and moves out of the flattening machine 1 to be cut by the cutting blade 211.

[0041] As an embodiment provided by the present invention, the locking sleeve 41 is provided with an oil guide channel 42 fixedly connected to the oil bottle, the oil guide channel 42 faces the elastic inclined plate 43, and the oil guide channel 42 is turned over with the elastic inclined plate 43 to open the oil guide channel 42 to lubricate the pre-pressing head 32; A bending groove 431 is formed on the elastic inclined plate 43 , a blocking block 421 is slidably connected to the oil guide passage 42 , and a pulling rope 44 is provided between the elastic inclined plate 43 and the blocking block 421 .

[0042] Specifically, the oil guide channel 42 is semicircular, and is provided with an oil inlet pipe, which is fixedly connected to the oil bottle. The oil guide channel 42 is provided with a plurality of oil distribution channels, which are respectively oriented toward the bending groove 431 of the elastic inclined plate 43. A sealing block 421 is slidably connected to the oil distribution channel, and the sealing block 421 is pulled by a spring to always block the oil distribution channel. When the elastic inclined plate 43 is pushed by the pre-pressing head 32 to be bent along the bending groove 431, the pulling rope 44 will pull out the oil distribution channel to allow the lubricating oil to seep onto the elastic inclined plate 43, and lubricate the pre-pressing head 32 via the elastic inclined plate 43 to reduce wear.

[0043] When in use, the steel plate 10 enters the flattening machine 1 along the rotation of the first supporting roller 21. At this time, the pre-pressing head 32 facing the locking sleeve 41 is limited by the bending force of the elastic inclined plate 43 to compress the elastic support block 34 to deform, and at the same time, the lubricating oil seeps onto the elastic inclined plate 43, and lubricates the pre-pressing head 32 through the elastic inclined plate 43, while the matching block 33 facing the locking sleeve 41 does not exert force on the elastic support block 34. As the first supporting roller 21 rotates, the pre-pressing head 32 will tilt and be limited by the first slide groove 312 to roll the steel plate 10 and cooperate with the matching block 3 3, a convex point is rolled out until the pre-pressing head 32 is perpendicular to the steel plate 10, and the rolling step is completed. During this period, when the pressure of the pre-pressing blade 321 is too large, the elastic support block 34 is deformed and compressed. At this time, the pre-pressing head 32 can flip along a convex point and slide along the second slide groove 351 to unload the pre-pressing blade 321. When the deformation range of the elastic support block 34 is too large, the insertion rod 352 will be inserted into the support groove 343 to limit the deformation range of the elastic support block 34, and then the steel plate 10 enters the flattening machine 1 to slightly flatten the convex point, and is moved out of the flattening machine 1 to be cut by the cutting blade 211.

[0044] As the best embodiment provided by the present invention, the pre-pressing head 32 is symmetrically provided with a second movable groove 323, wherein: The second movable groove 323 moves along with the pre-pressing head 32 and moves toward one of the double arc convex heads 313; The elastic inclined plate 43 is inserted into the second movable groove 323 .

[0045] Specifically, a second movable groove 323 is symmetrically opened on the pre-pressing head 32, and the second movable groove 323 facilitates the elastic inclined plate 43 to be inserted into the second movable groove 323 to increase the pushing force on the pre-pressing head 32, and when the pre-pressing head 32 is compressed, the second movable groove 323 can also face one of the double arc convex heads 313, so that the pre-pressing head 32 can rotate slightly to unload the force.

[0046] During use, the steel plate 10 enters the flattening machine 1 along the rotation of the first supporting roller 21. At this time, the pre-pressing head 32 facing the locking sleeve 41 will be limited by the bending force of the elastic inclined plate 43 to compress the elastic support block 34 to deform, and at the same time, the lubricating oil will seep onto the elastic inclined plate 43, and lubricate the pre-pressing head 32 through the elastic inclined plate 43, while the matching block 33 facing the locking sleeve 41 will not exert force on the elastic support block 34. As the first supporting roller 21 rotates, the pre-pressing head 32 will tilt and be limited by the first slide groove 312 to roll the steel plate 10 and cooperate with the matching block 33 to roll out convex points until the pre-pressing head 32 is perpendicular to the steel plate 10 to complete the rolling point step. During this period, when the pressure of the pre-pressing blade 321 is too large, the elastic support block 34 is deformed and compressed. At this time, the second movable groove 323 on the pre-pressing head 32 passes over a convex point, and the pre-pressing head 32 can flip along a convex point and slide along the second slide groove 351 to unload the pre-pressing blade 321. When the deformation amplitude of the elastic support block 34 is too large, the insertion rod 352 will be inserted into the support groove 343 to limit the deformation amplitude of the elastic support block 34, and then the steel plate 10 enters the flattening machine 1 to flatten the convex point slightly, and is moved out of the flattening machine 1 to be cut by the cutting blade 211.

[0047] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
