Description

Technical Field

[0001] The present invention relates to the technical field of metal plate finishing equipment, and in particular to a high-speed finishing flying shear for high-strength steel coils and a servo control method thereof. Background Art

[0002] Steel coil shearing flying shear units are widely used in the steel processing industry. They are mainly responsible for cutting continuously produced steel coils into the required size. With the improvement of industrial automation, the requirements for production efficiency and precision of this equipment are also getting higher and higher.

[0003] As the core equipment in steel plate finishing lines, flying shears undertake the crucial task of cutting steel coils to length while operating at high speed. With the advancement of lightweight vehicles and high-end equipment manufacturing, the use of high-strength steel with a tensile strength of 590 MPa or higher has been increasing annually. However, the microstructural characteristics of high-strength steel (martensite content ≥50%) can cause the steel coils to tear and break during shearing, resulting in burrs at the ends.

[0004] Therefore, it is necessary to make a device that can prevent burrs from appearing on the finished steel coils after cutting to solve this problem.

[0005] The shearing mechanism, peeling shaft and spring shaft in this application are all prior art, and the following is an explanation of them:

[0006] The shearing mechanism is the component of the flying shear that directly performs the shearing action. Through the relative movement of the upper and lower blades, it applies shearing force to the high-speed moving metal strip or wire, causing it to break and separate. Its function is similar to that of "scissors", but it needs to adapt to high-speed, continuous shearing conditions, and requires higher precision and reliability.

[0007] The rotary shear is a key component that drives the blades to rotate, and plays a leading role in rotary shears in particular. Its high-speed rotation creates a continuous cutting edge for the blades, adapting to the shearing needs of high-speed moving materials. Its function is similar to a "rotating pair of scissors," enabling continuous shearing without pause.

[0008] Spring shaft

[0009] Definition: An axial part that integrates a clockwork spring (coil spring) and stores and releases force through rotation. It is a core component for mechanical energy storage and power transmission.

[0010] Structure: The shaft is usually a cylindrical metal rod with a smooth surface or a slot, which is used to fix the inner ring of the mainspring. There may be shoulders, threads or limit structures at both ends of the shaft, which are connected to the outer casing or winding reel.

[0011] The cutting edges on both sides of the steel coil after cutting are the cutting edges of the steel coil. Summary of the Invention

[0060] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0061] The present invention provides a high-speed finishing flying shear for high-strength steel coils and a servo control method thereof.

[0062] Please refer to Figures 1 to 7 The high-speed finishing shear for high-strength steel coils comprises a transversely arranged bottom plate 1, wherein a cutting assembly 2, a trimming assembly 3 and a discharge assembly 4 are sequentially arranged above the bottom plate 1 in the extending direction thereof; and further comprising a moving assembly 5 respectively arranged on the cutting assembly 2, the trimming assembly 3 and the discharge assembly 4 for driving the steel coils to move.

[0063] The cutting component 2 is used to cut the steel coil; the trimming component 3 is used to receive the steel coil cut by the cutting component 2 and trim the burrs on both sides of the steel coil; the discharge component 4 is used to move the steel coil trimmed by the trimming component 3 out of the trimming component 3.

[0064] The technical solution of the present invention solves the core burr problem: by adding an independent trimming component 3, secondary trimming is performed on both sides of the high-strength steel coil immediately after cutting, completely eliminating the tearing burrs caused by the high martensite content.

[0065] Full process automation: Cutting → trimming → nesting three components are integrated, and combined with the mobile component 5 to achieve continuous operation and improve production efficiency (especially suitable for high-speed production lines of high-strength steel above 590MPa).

[0066] Compact structure: The horizontal base plate 1 connects the components in series, reducing the equipment footprint and facilitating production line layout.

[0067] Please refer to the attached Figure 7The moving assembly 5 includes a first bracket 51, with a first support plate 52 disposed transversely below the first bracket 51. A driving roller 53 is connected below the first support plate 52. Above the first bracket 51, at least one first servo hydraulic cylinder 54 is disposed for driving the first support plate 52 toward or away from the first bracket 51. The first servo hydraulic cylinder 54 drives the driving roller 53 up and down, dynamically adjusting the pressing force on the steel coil to prevent surface damage to high-strength steel caused by excessive pressure. The hydraulic cylinder's stroke can be flexibly adjusted to accommodate steel coils of varying thicknesses.

[0068] Please refer to the attached Figure 3 The cutting assembly 2 includes a horizontally arranged first work plate 21, symmetrically mounted with two movable assemblies 5. A shearing mechanism 22 for cutting steel coils is located between the two movable assemblies 5. The active rollers 53 on the two movable assemblies 5 and the rotary shearing axis of the shearing mechanism 22 rotate in the same direction. The first brackets 51 on the two movable assemblies 5 are fixed to the upper side of the first work plate 21. The movable assemblies 5 and the shearing mechanism 22 are integrated into the first work plate 21, shortening the sheet material transport distance and reducing the risk of sheet material vibration after shearing.

[0069] Please refer to the attached Figure 4 The trimming assembly 3 includes a second work plate 31 and a third work plate 32 that are laterally spaced apart. The second work plate 31 and the third work plate 32 are used to place the same steel coil together. The side of the second work plate 31 facing away from the third work plate 32 is close to the first work plate 21.

[0070] A first clamping assembly 33 is provided on the side of the second work plate 31 facing away from the third work plate 32, and a second clamping assembly 34 is provided on the side of the third work plate 32 facing away from the second work plate 31. The first clamping assembly 33 and the second clamping assembly 34 cooperate with each other to clamp the two cutting edges of the steel coil.

[0071] The trimming assembly 3 further includes a spacing adjustment assembly for causing the cutting edges of the steel coils on the second and third work plates 31 and 32, which are closer to the first work plate 21, to extend beyond the second work plate 31, and for causing the cutting edges of the steel coils on the third and second work plates 32 and 31, which are away from the first work plate 21, to extend beyond the third work plate 32.

[0072] A first trimming assembly 35 for trimming the trimming edge extending from the second working plate 31 is provided on the side of the first clamping assembly 33 facing away from the second clamping assembly 34. A second trimming assembly 36 for trimming the trimming edge extending from the third working plate 32 is provided on the side of the second clamping assembly 34 facing away from the first clamping assembly 33.

[0073] The spacing adjustment assembly is also used to adjust the spacing between the second and third work plates 31, 32, enabling the trimming assembly 3 to trim steel coils of varying sizes. Dual-plate spacing: The gap between the second and third work plates 32 leaves the raw edges of the steel coils exposed, creating physical space for precise trimming.

[0074] Bidirectional clamping assembly: The first and second clamping assemblies 34 fix the steel plate from both sides to prevent the high-strength steel cutting edge from vibrating during trimming and ensure the flatness of the cut surface (the burr height can be controlled within ±0.1mm).

[0075] The spacing adjustment component actively controls the position of the steel plate on the work plate: the raw edge near the cutting component 2 is forced to extend out of the second work plate 31

[0076] The burrs on the other side are made to extend out of the third working plate 32 ; ensuring that the burrs are 100% exposed in the cutting area, eliminating the trimming blind area.

[0077] The first trimming assembly 35 is responsible for trimming the rough edges (original cutting side) extending from the second working plate 31 ;

[0078] The second trimming assembly 36 is used to simultaneously trim the burrs extending from the third working plate 32 ;

[0079] The two knives work together to achieve simultaneous removal of burrs on both sides, increasing efficiency by more than 50%.

[0080] The spacing adjustment component changes the spacing between the second and third working plates 32:

[0081] Adaptable to different widths of steel coils (such as 800-2000mm range), product specifications can be switched without changing hardware, reducing downtime and meeting the needs of multiple batches and small batches of production.

[0082] Please refer to the attached Figure 4-6 The first clamping assembly 33 includes a second clamping block 341 disposed transversely above the second work plate 31 on a side facing away from the third work plate 32. A second bracket 332 connected to the second work plate 31 is disposed above the second clamping block 341. The second bracket 332 is provided with a third servo hydraulic cylinder 333 for moving the first clamping block 331 toward or away from the second work plate 31. The side of the first clamping block 331 facing away from the third work plate 32 and the side of the second work plate 31 facing away from the third work plate 32 are on the same vertical plane.

[0083] The second clamping assembly 34 includes a second clamping block 341 disposed transversely above the third work plate 32 on a side facing away from the second work plate 31. A third bracket 342 connected to the third work plate 32 is disposed above the second clamping block 341. The third bracket 342 is provided with a fourth servo hydraulic cylinder 343 for moving the second clamping block 341 toward or away from the third work plate 32. The side of the second clamping block 341 facing away from the second work plate 31 and the side of the third work plate 32 facing away from the second work plate 31 are on the same vertical plane.

[0084] A leveling plate 344 is frictionally engaged with the side of the second clamping block 341 facing away from the second work plate 31. A first electromagnet is provided on the side of the leveling plate 344 near the second clamping block 341. The second clamping assembly 34 also includes a Hall effect sensor for detecting whether the first electromagnet is attracting an object. A fifth servo hydraulic cylinder 345 is provided on the third bracket 342 for driving the leveling plate 344 toward or away from the third work plate 32, thereby positioning the leveling plate 344 between the second clamping block 341 and the third work plate 32.

[0085] A moving assembly 5 is provided above the second work plate 31. A receiving groove 32a is formed in a recessed manner on the upper side of the third work plate 32. A plurality of second servo hydraulic cylinders 346 are provided at the bottom of the receiving groove 32a. A conveyor belt 347 is supported and connected on one side of the plurality of second servo hydraulic cylinders 346 facing away from the bottom of the receiving groove 32a. The second servo hydraulic cylinders 346 are used to drive the conveyor belt 347 to extend out of or be received into the receiving groove 32a. The conveying direction of the conveyor belt 347 is from the second work plate 31 to the third work plate 32.

[0086] A light sensor is provided on the conveyor belt 347 for detecting whether there is a steel coil on the conveyor belt 347. If so, the first servo hydraulic cylinder 54 of the moving assembly 5 on the second work plate 31 contracts, causing the first servo hydraulic cylinder 54 to leave the steel coil, and the second servo hydraulic cylinder 346 drives the conveyor belt 347 to extend out of the receiving slot 32a. At the same time, the conveyor belt 347 operates to drive the steel coil to continue moving toward the side away from the second work plate 31 until the Hall sensor detects that the side of the steel coil away from the second work plate 31 contacts the first electromagnet and stops (Hall sensor detection principle: after attracting an object, the magnetic field around the electromagnet weakens. When the magnetic field is below a threshold, it indicates that the first electromagnet has attracted an object). At the same time, the second servo hydraulic cylinder 346 drives the conveyor belt 347 down to be accommodated in the receiving slot 32a. The provision of the transmission belt can eliminate the clamping force on the movement of the steel coil, thereby allowing the side of the steel coil away from the second work plate 31 to be completely attached to the first electromagnet, thereby completing the position correction of the steel coil.

[0087] After the steel coil enters the step where one end of the steel coil extends out of the second work plate 31 and the other end extends out of the third work plate 32, the third servo hydraulic cylinder 333 drives the first clamping block 331 to move toward the side close to the second work plate 31, so that the first clamping plate clamps the steel coil on the second work plate 31; the fourth servo hydraulic cylinder 343 drives the second clamping block 341 to move toward the side close to the third work plate 32, so that the second clamping plate clamps the steel coil on the third work plate 32;

[0088] After the first trimming assembly 35 and the second trimming assembly 36 perform the step of trimming the side edges of the steel coil, the second clamping plate and the first clamping plate are separated from the steel coil;

[0089] After the second electromagnet 10 executes the power-off step, the second servo hydraulic cylinder 346 drives the conveyor belt 347 to extend out of the receiving groove 32a, and the active roller 53 of the moving assembly 5 located above the second working plate 31 descends to drive the steel coil to move toward the side of the third working plate 32. At the same time, the transmission belt drives the steel coil to move toward the fourth working plate 41 until the steel coil enters the steel coil.

[0090] Hall sensor + electromagnet: Detects the position of the steel coil and adjusts it by adsorption to ensure that the edge is aligned with the cutting blade (accuracy ±0.1mm); the conveyor belt 347 descends to eliminate clamping force interference and prevent sheet warping; the clamping block aligns with the side of the work plate to protect the sheet edge during clamping and prevent brittle cracking of high-strength steel; clamping → trimming → release → conveying are automatically linked to reduce manual intervention.

[0091] Please refer to the attached Figure 4-5 The first trimming assembly 35 includes a first servo slide 351 disposed on the side of the first clamping block 331 facing away from the third work plate 32. A first connecting rod 352 is provided on the slider of the first servo slide 351. The end of the first connecting rod 352 facing away from the slider of the first servo slide 351 is connected to a first cutting blade 353. The blade of the first cutting blade 353 is on the same vertical plane as the side of the first clamping block 331 facing away from the third work plate 32.

[0092] The second cutting assembly 2 includes a second servo slide 361 arranged on the side of the second clamping block 341 facing away from the second work plate 31, and a second connecting rod 362 is provided on the slider of the second servo slide 361. The end of the second connecting rod 362 facing away from the slider of the second servo slide 361 is connected to a second cutting knife 363, and the blade of the second cutting knife 363 is on the same vertical plane as the side of the second clamping block 341 facing away from the second work plate 31. After the first and second clamping blocks 331 and 341 clamp the steel coil, the first servo slide 351 drives the first cutting blade 353 to move along the side of the second work plate 31, trimming the portion of the steel coil that extends beyond the second work plate 31 and removing any burrs. The second servo slide 361 drives the second cutting blade 363 to move along the side of the third work plate 32, trimming the portion of the steel coil that extends beyond the third work plate 32 and removing any burrs. The cutting blades move along the edge of the work plate, completely removing any burrs. The servo slide drives the cutting blades, keeping their path parallel to the edge of the plate (with an error of ≤0.05mm) to avoid uneven cuts.

[0093] Please refer to the attached Figure 2 and 4 A suction plate 9 is vertically provided between the second working plate 31 and the third working plate 32.

A plurality of spring shafts 11 are spaced apart on the side of the second working plate 31 close to the third working plate 32. A steel belt 12 is wound around the spring shaft 11, and the end of the steel belt 12 facing away from the spring shaft 11 is fixed to the upper side of the third working plate 32. The plurality of second electromagnets 10 are spaced apart between the two steel belts 12. A first push rod 17 is transversely provided on the side of the first pillar 6 close to the third working plate 32 for pushing the suction plate 9 toward the third working plate 32. A second push rod 18 is transversely provided on the side of the second pillar 7 close to the second working plate 31 for pushing the suction plate 9 toward the second working plate 31. After the correction step of the steel coil position is completed, the second electromagnet 10 absorbs the steel coil, and the steel belt 12 bridges the gap between the working plates to prevent the plate from falling and getting stuck in the equipment (especially thin-gauge high-strength steel); after the second clamping plate and the third clamping plate execute the step of moving away from the steel coil, the second electromagnet 10 is powered off and stops absorbing the tempered plate.

[0094] Please refer to the attached Figure 2A plurality of first pillars 6 are provided below the second work plate 31. Each of the first pillars 6 is slidably disposed on the bottom plate 1.

Each of the second pillars 7 is slidably disposed on the bottom plate 1. The sliding directions of the first pillars 6 and the second pillars 7 are the same.

[0095] The spacing adjustment assembly includes a sixth servo hydraulic cylinder 37 for driving the movement of the first support 6 and a seventh servo hydraulic cylinder 38 for driving the movement of the second support 7. After the second electromagnet 10 performs the step of attracting the steel coil, the sixth servo hydraulic cylinder 37 and the seventh servo hydraulic cylinder 38 operate synchronously to move the second work plate 31 and the third work plate 32 closer to each other, causing one end of the steel coil to extend out of the second work plate 31 and the other end to extend out of the third work plate 32, and the second work plate 31 and the third work plate 32 move the same distance. After the conveyor belt 347 performs the step of driving the steel coil away from the third work plate 32, the sixth servo hydraulic cylinder 37 and the seventh servo hydraulic cylinder 38 operate synchronously to move the second work plate 31 and the third work plate 32 away from each other, thereby resetting the second work plate 31 and the third work plate 32 to facilitate the next step of cutting the steel coil.

[0096] The sixth servo hydraulic cylinder 37 and the seventh servo hydraulic cylinder 38 are further used to adjust the distance between the second working plate 31 and the third working plate 32 so that the second working plate 31 and the third working plate 32 can adapt to steel coils of different sizes.

These third support pillars 8 slide on the base plate 1 in the same direction as the second support pillars 7. The discharge assembly 4 also includes an eighth servo hydraulic cylinder 42 mounted on the base plate 1 to move the third support pillars 8. The fourth work plate 41 receives the trimmed sheets, which are then removed from the production line by the moving assembly 5, forming a closed-loop production flow. The eighth servo hydraulic cylinder 42 adjusts the position of the third support pillars 8 to adjust the position of the fourth work plate 41.
