[0002] A shearing device is a device that uses a blade to shear a plate. When the existing shearing device is used, the plate is generally placed, and the blade is moved downward by a hydraulic cylinder to cut the plate.

[0015] A plate shearing method for processing and manufacturing a steel structure, the method comprising the following steps:
[0016] Step 1: When using, place the steel plate on multiple traction rollers. The setting of multiple traction rollers facilitates the movement of the steel plate. When the side of the steel plate contacts the baffle, the steel plate cannot move. Then, start the two alignment cylinders to extend their output ends, so that the two clamping plates are close to each other to clamp the two sides of the steel plate, so that the steel plate will not tilt during cutting;
[0017] Step 2: Start two adjusting cylinders as needed to move the U-shaped moving plate, which moves the moving cutter, so that the distance between the moving cutter and the fixed cutter changes, and steel plates of different lengths can be cut. When the length is adjusted, start the two clamping cylinders to stretch their output ends, thereby driving the two clamping plates to move downward, thereby clamping the steel plate from the top, so that the steel plate will not shake when being cut from both sides;
[0018] Step 3, start the two first hydraulic cylinders to stretch their output ends, so that the two moving rods, the two fixed bases and the two fixed cutters move downward, and at the same time start the two second hydraulic cylinders to stretch their output ends, so that the two moving bases and the two moving cutters move downward. The two moving rods will drive the two horizontal rods and the rotating shaft to move downward during the movement, and the rotating shaft will squeeze the inclined inner wall of the U-shaped inclined plate, so that the U-shaped inclined plate moves away from the U-shaped fixed plate. The movement of the U-shaped inclined plate drives the movement of the U-shaped vertical plate and the connecting plate, and the movement of the connecting plate drives the movement of the baffle plate, and the baffle plate continues to move away from the fixed cutter. The cutting is not affected, and the baffle is separated from the side of the steel plate. At the same time, the movement of the baffle drives the two L-shaped rods to move, and the movement of the two L-shaped rods drives the two racks to move, so that the two gears rotate, thereby causing the limit column and the worm to rotate, and the rotation of the worm drives the worm wheel to rotate, and the rotation of the worm wheel causes the two eccentric columns to rotate, and the two eccentric columns rotate to squeeze the inner walls of the two extrusion holes, so that the two L-shaped rods move away from each other, and then the two L-shaped slides, the two alignment cylinders and the two clamping plates move away from each other, so that the two clamping plates no longer clamp the two sides of the steel plate, and at this time, only the two clamping plates press the top of the steel plate;
[0019] Step 4, when the shaft moves downward into the U-shaped vertical plate, the fixed cutter and the movable cutter do not contact the steel plate at this time. Since the U-shaped vertical plate is vertically arranged, the movement of the shaft will not cause the U-shaped vertical plate, the U-shaped inclined plate and the baffle plate to move. At this time, the fixed cutter and the movable cutter continue to move downward to cut. Since the baffle plate is staggered with the vertical side of the fixed cutter, the steel plate is cut into three sections, and the sides of the fixed cutter and the movable cutter close to each other are vertically arranged, so that the steel plate in the middle is The plate cut is smooth. When the steel plate is cut by the fixed cutter, the inclined surface of the fixed cutter will squeeze the steel plate, so that the part of the steel plate close to the baffle will be close to the baffle after cutting, and then fall into the collection box for collection. When the steel plate is cut by the mobile cutter, the inclined surface of the mobile cutter will squeeze the steel plate, so that the part of the steel plate close to the mounting bar will be away from the U-shaped mobile plate after cutting, and the cut is uneven. During the subsequent continuous cutting, the uneven part continues to align with the baffle, so that the uneven part is cut off by the fixed cutter in the later stage.
[0020] Step 5. After the cutting is completed, start the two clamping cylinders to move the two clamping plates upward, then start the pushing cylinder to move the push rod and the L-shaped connecting rod, so that the push plate moves, so as to push the cut steel plate away for unloading, and then start the two alignment cylinders to retract the two clamping plates, start the two second hydraulic cylinders and the two first hydraulic cylinders to shrink their output ends, and restore the device to its original state.
[0021] In summary, the technical effects and advantages of the present invention are as follows:
[0022] The present invention has a reasonable structure. The vertical cutting mechanism and the deforming cutting mechanism can be moved by two adjusting cylinders, so that plates of different lengths can be cut as needed. The position where the plate is deformed can be aligned with the deforming cutting mechanism by the baffle plate, so that too much plate will not be cut. During cutting, the two alignment mechanisms center the plate to avoid tilting. The deforming cutting mechanism will cause the baffle plate and the two alignment mechanisms to give way, so that when the plate is deformed and generates extrusion pressure during cutting, the baffle plate and the two alignment mechanisms will not be affected.
[0023] When cutting, the two moving rods of the present invention will drive the two horizontal rods and the rotating shaft to move downward during the movement, and the rotating shaft will squeeze the inclined inner wall of the U-shaped inclined plate, so that the U-shaped inclined plate is away from the U-shaped fixed plate, and the movement of the U-shaped inclined plate drives the movement of the U-shaped vertical plate and the connecting plate, and the movement of the connecting plate drives the movement of the baffle plate, and the baffle plate continues to move away from the fixed cutter, and the baffle plate is separated from the side of the steel plate, thereby not affecting the cutting, and after cutting, the part of the steel plate close to the baffle plate will be close to the baffle plate after being cut off, and thus fall into the collection box for collection.
[0024] In the present invention, during cutting, the rotation of the worm drives the rotation of the worm wheel, and the rotation of the worm wheel causes the two eccentric columns to rotate. The two eccentric columns rotate to squeeze the inner walls of the two extrusion holes, so that the two L-shaped rods move away from each other, and then the two L-shaped slides, the two alignment cylinders and the two clamping plates move away from each other, so that the two clamping plates no longer clamp the two sides of the steel plate, and now only the two clamping plates clamp the top of the steel plate.
[0025] In the present invention, two adjusting cylinders are started as needed to move the U-shaped movable plate, and the movement of the U-shaped movable plate causes the movable cutter to move, so that the distance between the movable cutter and the fixed cutter changes, and steel plates of different lengths can be cut. When the length is adjusted, the output ends of the two clamping cylinders are stretched by starting the two clamping cylinders, thereby driving the two clamping plates to move downward, thereby clamping the steel plate from the top, so that the steel plate will not shake when being cut from both sides.
[0026] In the present invention, when in use, the steel plate is placed on a plurality of traction rollers. The arrangement of the plurality of traction rollers facilitates the movement of the steel plate. When the side of the steel plate contacts the baffle plate, the steel plate cannot move. Then, the output ends of the steel plate are extended by starting the two alignment cylinders, so that the two clamping plates are close to each other to clamp the two sides of the steel plate, so that the steel plate will not tilt during cutting.

During cutting, the two alignment mechanisms will center the plate to avoid tilting, and the deforming cutting mechanism will cause the baffle 18 and the two alignment mechanisms to avoid, so that when the plate is deformed and generates extrusion pressure during cutting, it will not affect the baffle 18 and the two alignment mechanisms.
[0040] like Figure 1 and Figure 2 As shown, the deformation cutting mechanism includes a U-shaped fixed plate 2 fixedly mounted on the top of the shearing table 1, two first hydraulic cylinders 4 are fixedly mounted on the top of the U-shaped fixed plate 2, and the output ends of the two first hydraulic cylinders 4 are fixedly mounted with moving rods 5, the top ends of the two moving rods 5 penetrate the top of the U-shaped fixed plate 2 and are fixedly mounted with a fixed base 6, and the bottom of the fixed base 6 is fixedly mounted with a fixed cutter 7, the sides of the two adjusting cylinders 45 are fixedly connected to the sides of the U-shaped fixed plate 2, and the sides of the two moving rods 5 are installed in coordination with the extrusion avoidance mechanism. The two first hydraulic cylinders 4 are started to stretch their output ends, so that the two moving rods 5, the two fixed bases 6 and the two fixed cutters 7 move downward, so that the deformed part of the plate can be cut.
[0041] like Figure 1 and Figure 2 As shown, the extrusion avoidance mechanism includes a horizontal rod 14 fixedly mounted on the sides of the two moving rods 5, a rotating shaft 15 fixedly mounted on the sides of the two horizontal rods 14 close to each other, a connecting plate 19 fixedly mounted on the side of the baffle 18, a U-shaped vertical plate 20 with an opening facing upward fixedly mounted on the side of the connecting plate 19 away from the baffle 18, a U-shaped inclined plate 21 fixedly mounted on the top of the U-shaped vertical plate 20, and one end of the rotating shaft 15 penetrates the U-shaped inclined plate 21. During the movement of the two moving rods 5, the two horizontal rods 14 and the rotating shaft 15 will be driven to move downward, and the rotating shaft 15 will squeeze the inclined inner wall of the U-shaped inclined plate 21, so that the U-shaped inclined plate 21 is away from the U-shaped fixed plate 2, the movement of the U-shaped inclined plate 21 drives the U-shaped vertical plate 20 and the connecting plate 19 to move, and the movement of the connecting plate 19 drives the baffle 18 to move, and the baffle 18 continues to move away from the fixed cutter 7, and the baffle 18 is separated from the side of the steel plate, so as not to affect the cutting.

The output ends of the two second hydraulic cylinders 8 both pass through the top of the U-shaped movable plate 3 and are fixedly mounted with a movable base 9, and a movable cutter 10 is fixedly mounted on the bottom of the movable base 9, and the side where the movable cutter 10 and the fixed cutter 7 are close to each other is vertically arranged, and the side where the movable cutter 10 and the fixed cutter 7 are away from each other is inclined, and two mounting bars 48 are fixedly mounted on the side of the U-shaped movable plate 3, and a plurality of traction rollers 49 are rotatably mounted on the sides where the two mounting bars 48 are close to each other.

The sides of the fixed cutter 7 and the movable cutter 10 close to each other are vertically arranged, so that the incision of the middle steel plate is smooth. When the steel plate is cut by the movable cutter 10, the inclined surface of the movable cutter 10 will squeeze the steel plate, so that the part of the steel plate close to the mounting strip 48 will be away from the U-shaped movable plate 3 after cutting, and the incision is uneven. During the subsequent continuous cutting, the uneven part continues to align with the baffle 18, so that the uneven part is cut off by the fixed cutter 7 in the later stage.
[0045] like Figure 1 and Figure 2As shown, cutting seats 11 are fixedly installed on the inner walls of both sides of the U-shaped movable plate 3 and the inner walls of both sides of the U-shaped fixed plate 2. The two cutting seats 11 correspond to the positions of the movable cutter 10 and the fixed cutter 7 respectively. The cutting seats 11 cooperate with the movable cutter 10 and the fixed cutter 7 to facilitate cutting. The cutting seats 11 and the top of the traction roller 49 are in the same horizontal position, so that the plate is horizontal after being placed. The sides of the U-shaped movable plate 3 and the U-shaped fixed plate 2 close to each other are fixedly installed with mounting blocks 12, and the tops of the two mounting blocks 12 are A clamping cylinder 13 is fixedly installed, and the output end of the clamping cylinder 13 passes through the top of the mounting block 12 and is fixedly installed with a clamping plate 50. By starting the two clamping cylinders 13, the output ends thereof are stretched, thereby driving the two clamping plates 50 to move downward, thereby clamping the steel plate from the top so that the steel plate will not shake when being sheared from both sides. Avoidance holes 22 are provided on the inner walls on both sides of the U-shaped fixed plate 2 and the inner walls on both sides of the U-shaped movable plate 3.

Since the baffle 18 and the vertical side of the fixed cutter 7 are staggered, the steel plate is cut into three sections, and the sides of the fixed cutter 7 and the movable cutter 10 close to each other are vertically arranged, so that the incision of the middle steel plate is flat. When the steel plate is cut by the fixed cutter 7, the inclined surface of the fixed cutter 7 will squeeze the steel plate, so that the part of the steel plate close to the baffle 18 will be close to the baffle 18 after cutting, and then fall into the collecting box 43 for collection.
[0049] A plate shearing method for processing and manufacturing a steel structure, the method comprising the following steps:
[0050] Step 1: When in use, place the steel plate on a plurality of traction rollers 49. The arrangement of the plurality of traction rollers 49 facilitates the movement of the steel plate. When the side of the steel plate contacts the baffle 18, the steel plate cannot move. Then, the two alignment cylinders 36 are started to extend their output ends, so that the two clamping plates 37 are close to each other to clamp the two sides of the steel plate, so that the steel plate will not tilt during cutting.
[0051] Step 2: Start the two adjusting cylinders 45 as needed to move the U-shaped movable plate 3. The movement of the U-shaped movable plate 3 causes the movable cutter 10 to move, so that the distance between the movable cutter 10 and the fixed cutter 7 changes, and steel plates of different lengths can be cut. When the length is adjusted, start the two clamping cylinders 13 to stretch their output ends, thereby driving the two clamping plates 50 to move downward, thereby clamping the steel plate from the top, so that the steel plate will not shake when being cut from both sides;
[0052] Step 3, start the two first hydraulic cylinders 4 to stretch their output ends, so that the two moving rods 5, the two fixed bases 6 and the two fixed cutters 7 move downward, and at the same time start the two second hydraulic cylinders 8 to stretch their output ends, so that the two moving bases 9 and the two moving cutters 10 move downward. During the movement of the two moving rods 5, the two horizontal rods 14 and the rotating shaft 15 will be driven to move downward. The rotating shaft 15 squeezes the inclined inner wall of the U-shaped inclined plate 21, so that the U-shaped inclined plate 21 is away from the U-shaped fixed plate 2. The movement of the U-shaped inclined plate 21 drives the U-shaped vertical plate 20 and the connecting plate 19 to move. The movement of the connecting plate 19 drives the baffle 18 to move. The baffle 18 continues to move away from the fixed cutter 7, so as not to affect the cutting. The baffle plate 18 is separated from the side of the steel plate, and the movement of the baffle plate 18 drives the two first L-shaped rods 23 to move, and the movement of the two first L-shaped rods 23 drives the two racks 24 to move, so that the two gears 28 rotate, thereby causing the limit column 26 and the worm 27 to rotate, and the rotation of the worm 27 drives the worm wheel 30 to rotate, and the rotation of the worm wheel 30 causes the two eccentric columns 31 to rotate, and the two eccentric columns 31 rotate to squeeze the inner walls of the two extrusion holes 33, so that the two second L-shaped rods 32 move away from each other, and then the two L-shaped slides 34, the two alignment cylinders 36 and the two clamping plates 37 move away from each other, so that the two clamping plates 37 no longer clamp the two sides of the steel plate, and at this time, only the two clamping plates 50 clamp the top of the steel plate;
[0053] Step 4, when the rotating shaft 15 moves downward into the U-shaped vertical plate 20, the fixed cutter 7 and the movable cutter 10 do not contact the steel plate. Since the U-shaped vertical plate 20 is vertically arranged, the movement of the rotating shaft 15 will not cause the U-shaped vertical plate 20, the U-shaped inclined plate 21 and the baffle 18 to move. At this time, the fixed cutter 7 and the movable cutter 10 continue to move downward to perform cutting. Since the baffle 18 is staggered with the vertical side of the fixed cutter 7, the steel plate is cut into three sections, and the sides of the fixed cutter 7 and the movable cutter 10 close to each other are vertically arranged, so that The incision of the steel plate in the middle is smooth. When the steel plate is cut by the fixed cutter 7, the inclined surface of the fixed cutter 7 will squeeze the steel plate, so that the part of the steel plate close to the baffle 18 will be close to the baffle 18 after cutting, and fall into the collection box 43 for collection. When the steel plate is cut by the movable cutter 10, the inclined surface of the movable cutter 10 will squeeze the steel plate, so that the part of the steel plate close to the mounting bar 48 will be away from the U-shaped movable plate 3 after cutting, and the incision is uneven. During the subsequent continuous cutting, the uneven part continues to align with the baffle 18, so that the uneven part is cut off by the fixed cutter 7 in the later stage.
[0054] Step 5. After the cutting is completed, the two clamping cylinders 13 are started to move the two clamping plates 50 upward, and then the pushing cylinder 38 is started to move the pushing rod 39 and the L-shaped connecting rod 40, so that the pushing plate 41 moves, so as to push the cut steel plate away for unloading, and then the two alignment cylinders 36 are started to retract the two clamping plates 37, and the two second hydraulic cylinders 8 and the two first hydraulic cylinders 4 are started to shrink their output ends, and the device returns to its original state.
