When the material plate needs to be sheared, an operator places the material plate on the operation table 1, the material plate moves between the lower blade 5 and the upper blade 4 from front to back, then the material plate is flattened through the arrangement mechanism 6, bending of the material plate is prevented, the material plate is pressed and fixed on the operation table 1 through the arrangement mechanism 6, then the feeding plate 2 is controlled to move downwards through the hydraulic power assembly, and the feeding plate 2 drives the upper blade 4 to shear the material plate through the adjusting mechanism 3.
Then, the tilting direction of the upper blade 4 is changed by the adjusting mechanism 3, and the upper blade 4 is moved up to the upper portion of the lower blade 5 by the hydraulic power assembly, and then the material plate is moved backward, and then the upper blade 4 is moved down again, thereby performing continuous plate shearing operation on the material plate.
Referring to fig. 1,6 and 7, the sorting mechanism 6 comprises a U-shaped frame 61 fixedly installed on the operation table 1, a plurality of hydraulic support columns 63 are arranged at equal intervals in the left-right direction at the lower part of the U-shaped frame 61 through a connecting assembly 62, and press rollers 65 for pushing the flattened material plates are arranged on the leftmost hydraulic support columns 63 and the rightmost hydraulic support columns 63 through swinging assemblies 64.
With continued reference to fig. 1, 6 and 7, the connection assembly 62 includes a mounting block 621 disposed on a lower side of the horizontal section of the U-shaped frame 61, the lower side of the mounting block 621 is fixedly connected with the corresponding hydraulic support column 63, and a bidirectional screw 622 is rotatably disposed on the operating table 1, and the bidirectional screw 622 is in threaded connection with the rightmost and leftmost mounting blocks 621.
The rightmost and leftmost mounting blocks 621 are slidably connected with the horizontal section of the U-shaped frame 61, the remaining mounting blocks 621 are fixedly connected with the U-shaped frame 61, and the bidirectional screw 622 is inserted through the middle mounting block 621 and is not engaged therewith.
Referring to fig. 1,3 and 6, two sliding blocks 66 which are symmetrically arranged left and right are arranged on the lower blade 5 in a sliding manner, a limit roller 661 is rotatably arranged on the upper side of the sliding block 66, and a linkage plate 662 which is in threaded connection with the bidirectional screw 622 is fixedly arranged on one side of the sliding block 66 away from the middle of the operating platform 1.
When the plate shearing operation is required to be performed on the material plate, an operator manually rotates the bidirectional screw 622 according to the left-right width of the material plate in advance, so that the bidirectional screw 622 drives the rightmost mounting block 621 and the leftmost mounting block 621, and the left-right adjusting positions of the two linkage plates 662, the linkage plates 662 drive the distance between the two limiting rollers 661 through the sliding blocks 66 to be equal to the width of the material plate, and meanwhile, the rightmost mounting block 621 and the leftmost mounting block 621 drive the hydraulic support columns 63 on the two limiting rollers to move to the left edge position and the right edge position of the material plate, so that the edge position of the material plate is pressed and fixed.
Referring to fig. 1, 6 and 7, the swing assembly 64 includes a connection stay 641 fixedly installed at the outer sides of the leftmost and rightmost hydraulic support columns 63, the connection stay 641 being hinged to the pressing roller 65 by a hinge plate 642 hinged thereto, the hinge plates 642 at the left and right sides being arranged in a splayed shape.
Referring to fig. 6 and 7, a gear 643 is fixedly mounted at the hinge position of the hinge plate 642 and the connection support plate 641, a rack 644 is slidably disposed on the connection support plate 641 along the vertical direction, a pressing plate 645 is fixedly mounted at the upper end of the rack 644 and sleeved outside the fixed section of the hydraulic support column 63 in a vertically sliding manner, and a compression spring is disposed between the pressing plate 645 and the lower portion of the telescopic section of the hydraulic support column 63.
In the initial state, the compression spring is in a compressed state, so that the compression spring can push the pressing plate 645 upwards through the self elastic force, the pressing plate 645 is embedded in the lower portion of the mounting block 621, and meanwhile, the included angle between the hinge plate 642 and the axial direction of the hydraulic support column 63 is smaller.
When the operator places the flitch on the operation panel 1, and makes the shearing position of flitch be located between the blade of upper blade 4 and lower blade 5 for the flitch is in between two spacing rollers 661, restricts the left and right directions of flitch through two spacing rollers 661, prevents that the flitch from crooked.
Simultaneously, all the hydraulic support columns 63 are elongated, so that the leftmost and rightmost hydraulic support columns 63 drive the connection support plates 641 thereon to synchronously move downwards, the connection support plates 641 drive the gears 643 to synchronously move downwards through the hinged plates 642, in the process, the lower parts of the compression springs move downwards along with the telescopic sections of the hydraulic support columns 63, but because the compression springs are in a compressed state, the compression springs are integrally elongated, the upper parts of the compression springs cannot move downwards along with the lower parts of the compression springs, the gears 643 are meshed with the racks 644 to rotate clockwise, and therefore the included angle between the hinge plates 642 and the axial directions of the hydraulic support columns 63 is further reduced by the gears 643.
When the hinged plate 642 drives the press roller 65 to move downwards to contact with the material plate, the material plate blocks the press roller 65, so that the connection support plate 641 drives the press roller 65 to lean against the material plate through the hinged plate 642 and moves in a direction away from the middle of the operation table 1, the press roller 65 flattens the material plate by pushing the material plate outwards, and the material plate is prevented from bending when being sheared.
In the process of flattening the material plate, the included angle between the hinged plate 642 and the axial direction of the hydraulic support column 63 is gradually increased, so that the hinged plate 642 pulls the rack 644 downwards through the gear 643, the rack 644 drives the pressing plate 645 to move synchronously, the pressing plate 645 presses the upper portion of the compression spring, the lower portion of the compression spring moves downwards along with the hydraulic support column 63, the total length of the compression spring is unchanged, the compression spring is in a compression state at the moment, and the pressing force of the compression roller 65 to the material plate is ensured through the elasticity of the compression spring to the pressing plate 645.
It should be noted that, the outside of the pressing roller 65 is provided with an anti-slip structure for increasing friction force, and the pressing roller 65 is more difficult to rotate due to the friction force between the pressing roller 65 and the hinged plate 642, so that the pressing roller 65 can push the material plate when moving on the material plate, and after the material plate is flattened, the pressing roller 65 overcomes the friction force between the pressing roller 65 and the hinged plate 642, so that the pressing roller 65 rolls on the material plate to prevent the material plate from being scratched.
The telescopic section of the hydraulic support column 63 is then moved down against the material plate, thereby pressing the material plate against the console 1.
Referring to fig. 1,2 and 3, the adjusting mechanism 3 includes a rotating member 31 rotatably disposed on the feed plate 2, the front portion of the rotating member 31 is in a rectangular block structure, the rear portion of the rotating member 31 is in a cylindrical structure, a cutter rest plate 32 is slidably disposed on the rectangular block structure of the rotating member 31, the lower end of the front side of the cutter rest plate 32 is connected with the upper blade 4 by means of a bolt connection, and the adjusting mechanism 3 further includes a linkage assembly 33 for controlling the upper blade 4 to change the tilting direction after each cutting.

In the initial state, the upper blade 4 is in a tilting posture with high left and low right, so that the upper blade 4 drives the rectangular block structure of the rotating member 31 to be in the tilting posture as well, the upper spring telescopic rod 333 pushes the right end of the fixed rod 331 downwards to deflect downwards, the upper spring telescopic rod 333 is in a compressed state, and the rotating member 31 drives the right lower end surface of the arc plate 311 to abut against the right part of the arc groove 312, so that the upper spring telescopic rod 333 is prevented from pushing the fixed rod 331 to deflect excessively through the elasticity of the upper spring telescopic rod 333.

When the hydraulic support column 63 is propped against the material plate, the feeding plate 2 is moved downwards through the hydraulic power assembly, the feeding plate 2 drives the upper blade 4 to move downwards synchronously through the rotating piece 31 and the cutter frame plate 32, so that the right side of the cutting edge of the upper blade 4 is contacted with the material plate, when the upper blade 4 is contacted with the material plate, the telescopic section of the hydraulic cylinder 313 extends out, the hydraulic cylinder 313 drives the upper blade 4 to slightly move and transversely move rightwards along the length direction of the cutter frame plate 32 through the cutter frame plate 32, the upper blade 4 gradually contacts the material plate in a sliding cutting mode during initial cutting, and local impact force is dispersed, so that the damage of instantaneous load to the blade is reduced, and the smoothness and stability of the cutting process are improved.
Then, the upper blade 4 and the lower blade 5 are matched to start complete plate shearing operation on the material plate, and as the upper blade just contacts the steel plate, the contact length of the blade and the material is longer, so that the initial shearing force reaches a peak value, the contact length gradually decreases along with the cutting of the blade into the material plate, and the shearing force correspondingly decreases, so that the impact of the material plate on the upper blade 4 gradually decreases in the shearing process, the impact force of the upper blade 4 on the initial plate shearing and the plate shearing process is relatively similar, the abrasion on the cutting edge of the upper blade 4 is effectively guaranteed to be uniform, the upper blade 4 is fully utilized, and the service life of the material plate shearing machine is prolonged.
When the cutting edge on the left side of the upper blade 4 moves to the lower portion of the lower blade 5, one shearing of the material plate is completed, and then the feeding plate 2 continues to move downward, so that the feeding plate 2 moves the fixing lever 331 into contact with the lower spring telescoping lever 333 by the rotating member 31, and so that the fixing lever 331 compresses the lower spring telescoping lever 333.
Then the lower deflector rod 335 contacts with the lower fixed plate 336, so that the lower fixed plate 336 pushes the lower deflector rod 335 upwards through a reaction force, the lower deflector rod 335 drives the lower locking post 334 to withdraw from the lower jack, so that the rotating member 31 is not locked any more, and then the spring telescopic rod 333 pushes the fixed rod 331 upwards through self elasticity, so that the fixed rod 331 drives the rotating member 31 to rotate, the rotating member 31 drives the left lower end surface of the arc plate 311 to abut against the left part of the arc groove 312, and simultaneously the rotating member 31 drives the cutter frame plate 32 and the upper cutter blade 4 to rotate to a left-low right-high inclined posture.
When the cutter rest plate 32 and the upper blade 4 are in a tilting posture with left low and right high, the rotating member 31 drives the axis of the lower locking post 334 to rotate until an included angle exists between the axis of the lower jack, and the axis of the upper locking post 334 is collinear with the axis of the upper jack, so that the coil spring pushes the upper locking post 334 to be inserted into the jack of the upper jack through the elasticity of the coil spring, thereby locking the rotating member 31 and the feeding plate 2 together again, and fixing the rotating angle of the cutter rest plate 32 and the upper blade 4.
