Description

Technical Field

[0001] This invention relates to the field of metal sheet finishing equipment technology, specifically to a high-speed precision finishing flying shear for high-strength steel coils and its servo control method. Background Technology

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

[0003] As a core piece of equipment in steel plate finishing lines, the flying shear machine undertakes the crucial task of cutting steel coils to length at high speeds. With the development of automotive lightweighting and high-end equipment manufacturing, the application rate of high-strength steel with a tensile strength ≥590MPa is increasing year by year. However, the microstructure characteristics of high-strength steel (martensite content ≥50%) cause the steel coil to tear and break during cutting by the flying shear machine, resulting in burrs at the ends.

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

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

[0006] The shearing mechanism is the component of the flying shear machine 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 "scissors," but it needs to adapt to high-speed, continuous shearing conditions, and has higher requirements for precision and reliability.

[0007] The rotary shearing shaft is a key component in flying shears that drives the blades to rotate, especially in rotary flying shears where it plays a dominant role. Through high-speed rotation, it creates continuous shearing edges on the blades, adapting to the shearing requirements of high-speed moving materials. Its function is similar to that of a "rotating pair of scissors," enabling uninterrupted continuous shearing.

[0008] mainspring shaft

[0009] Definition: A shaft-shaped part that integrates a spring (coil spring) and stores and releases energy 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 grooves to fix the inner ring of the spring; the two ends of the shaft may have shoulders, threads or limiting structures to connect to the housing or reel.

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

[0034] S2: Control the first servo hydraulic cylinder above the second working plate to retract so that the active roller is disengaged from the steel coil. The conveyor belt transports the steel coil to the third working plate until the Hall sensor detects that the edge of the steel coil is attracted to the first electromagnet.

[0039] S7: Control the first clamping block and the second clamping block to release the steel coil, and simultaneously control the second electromagnet to release the steel coil;

[0040] S8: Control the sixth and seventh servo hydraulic cylinders to drive the second and third working plates to reset to the initial distance;

[0041] S9: The moving component of the control discharge assembly drives the active roller to press the steel coil and drives the steel coil to move out of the trimming assembly.

[0042] The technical solution of this invention solves the core burr problem by adding an independent trimming component, which performs secondary trimming on both sides of the high-strength steel coil immediately after cutting, thus completely eliminating the tearing burrs caused by high martensite content.

[0043] Full-process automation: The three components of cutting, trimming and material feeding are integrated and combined with moving components to achieve continuous operation and improve production efficiency (especially suitable for high-speed production lines of high-strength steel above 590MPa).

[0044] Compact structure: The horizontal base plate connects all components, reducing the equipment footprint and facilitating production line layout. Attached Figure Description

[0061] This invention proposes a high-speed precision finishing flying shear machine for high-strength steel coils and its servo control method.

[0062] Please refer to Figures 1 to 7 The high-speed finishing flying shear for high-strength steel coils includes a horizontally arranged base plate 1, and a cutting component 2, an edge trimming component 3, and a discharge component 4 are arranged sequentially above the extending direction of the base plate 1; it also includes a moving component 5 for driving the steel coil to move, which is respectively distributed on the cutting component 2, the edge trimming component 3, and the discharge component 4.

[0063] The cutting component 2 is used to cut the steel coil; the trimming component 3 is used to receive the steel coil after it has been cut by the cutting component 2 and to trim the rough edges 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 cutting component 2 includes a first working plate 21 arranged horizontally. The first working plate 21 is symmetrically provided with two moving components 5. A shearing mechanism 22 for cutting steel coils is provided between the two moving components 5. The rotation directions of the active rollers 53 on the two moving components 5 and the rotary cutting shaft of the shearing mechanism 22 are in the same direction. The first brackets 51 on the two moving components 5 are fixed to the upper side of the first working plate 21.

[0065] The trimming assembly 3 includes a second working plate 31 and a third working plate 32 arranged horizontally at intervals. The second working plate 31 and the third working plate 32 are used to place the same steel coil together. The side of the second working plate 31 facing away from the third working plate 32 is close to the first working plate 21.

[0066] The second working plate 31 is provided with a first clamping component 33 on the side opposite to the third working plate 32, and the third working plate 32 is provided with a second clamping component 34 on the side opposite to the second working plate 31; the first clamping component 33 and the second clamping component 34 cooperate to clamp the two sides of the steel coil cutting edge.

[0067] The trimming assembly 3 also includes a spacing adjustment assembly for extending the cutting edge of the steel coil located on the second working plate 31 and the third working plate 32 on the side close to the first working plate 21 out of the second working plate 31, and for extending the cutting edge of the steel coil located on the third working plate 32 and the second working plate 31 on the side away from the first working plate 21 out of the third working plate 32.

[0068] The first clamping assembly 33 is provided with a first trimming assembly 35 for trimming the trimming edge extending from the second working plate 31 on the side opposite to the second clamping assembly 34, and the second clamping assembly 34 is provided with a second trimming assembly 36 for trimming the trimming edge extending from the third working plate 32 on the side opposite to the first clamping assembly 33.

[0069] The spacing adjustment component is also used to adjust the spacing between the second working plate 31 and the third working plate 32 so that the trimming component 3 can trim steel coils of different sizes.

[0070] In the technical solution of this invention, the core burr problem is solved by adding an independent trimming component 3, which performs secondary trimming on both sides of the high-strength steel coil immediately after cutting, thus completely eliminating the tearing burrs caused by high martensite content.

[0071] Full-process automation: The three components of cutting, trimming and material feeding are integrated, and the moving component 5 enables continuous operation and improves production efficiency (especially suitable for high-speed production lines of high-strength steel above 590MPa).

[0072] Compact structure: The horizontal base plate 1 connects all components in series, reducing the equipment footprint and facilitating production line layout.

[0073] Please refer to the appendix. Figure 7 The moving component 5 includes a first bracket 51, with a first support plate 52 horizontally positioned below the first bracket 51. An active roller 53 is connected below the first support plate 52. At least one first servo hydraulic cylinder 54 is positioned above the first bracket 51 to move the first support plate 52 towards or away from the first bracket 51. The first servo hydraulic cylinder 54 drives the active roller 53 to rise and fall, dynamically adjusting the clamping force on the steel coil to prevent surface damage to high-strength steel due to excessive pressure. The hydraulic cylinder stroke is flexibly adjustable, accommodating steel coils of different thicknesses.

[0074] Please refer to the appendix. Figure 3The cutting assembly 2 includes a horizontally arranged first working plate 21. Two moving assemblies 5 are symmetrically arranged on the first working plate 21. A shearing mechanism 22 for cutting steel coils is provided between the two moving assemblies 5. The rotation directions of the drive rollers 53 on the two moving assemblies 5 and the rotary cutting shaft of the shearing mechanism 22 are the same. First brackets 51 on the two moving assemblies 5 are fixed to the upper side of the first working plate 21. The moving assemblies 5 and the shearing mechanism 22 are integrated into the first working plate 21, shortening the plate transport distance and reducing the risk of plate vibration after shearing.

[0075] Please refer to the appendix. Figure 4 The trimming assembly 3 includes a second working plate 31 and a third working plate 32 arranged horizontally at intervals. The second working plate 31 and the third working plate 32 are used to place the same steel coil together. The side of the second working plate 31 facing away from the third working plate 32 is close to the first working plate 21.

[0076] The second working plate 31 is provided with a first clamping component 33 on the side opposite to the third working plate 32, and the third working plate 32 is provided with a second clamping component 34 on the side opposite to the second working plate 31; the first clamping component 33 and the second clamping component 34 cooperate to clamp the two sides of the steel coil cutting edge.

[0077] The trimming assembly 3 also includes a spacing adjustment assembly for extending the cutting edge of the steel coil located on the second working plate 31 and the third working plate 32 on the side close to the first working plate 21 out of the second working plate 31, and for extending the cutting edge of the steel coil located on the third working plate 32 and the second working plate 31 on the side away from the first working plate 21 out of the third working plate 32.

[0078] The first clamping assembly 33 is provided with a first trimming assembly 35 for trimming the trimming edge extending from the second working plate 31 on the side opposite to the second clamping assembly 34, and the second clamping assembly 34 is provided with a second trimming assembly 36 for trimming the trimming edge extending from the third working plate 32 on the side opposite to the first clamping assembly 33.

[0079] The spacing adjustment component is also used to adjust the spacing between the second working plate 31 and the third working plate 32, so that the trimming component 3 can trim steel coils of different sizes. The double working plate spacing layout: through the gap design of the second and third working plates 32, the rough edge areas on both sides of the steel coil are exposed, creating physical space for precise trimming.

[0080] Two-way 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).

[0081] The spacing adjustment component actively controls the position of the steel plate on the working plate: it forces the rough edges near the cutting component 2 to extend out of the second working plate 31.

[0082] Make the rough edge on the other side extend out of the third working plate 32; ensure that the rough edge is 100% exposed to the cutting area and eliminate blind spots in trimming.

[0083] First trimming component 35: Responsible for cutting off the rough edges (original trimming side) extending out of the second working plate 31.

[0084] Second trimming component 36: Simultaneously trims the rough edges extending from the third working plate 32;

[0085] The dual-blade system enables simultaneous removal of burrs on both sides, improving efficiency by more than 50%.

[0086] The spacing adjustment component changes the spacing between the second and third work plates 32:

[0087] It is compatible with steel coils of different widths (e.g., 800-2000mm) and can switch product specifications without changing hardware, reducing downtime and meeting the needs of multi-batch small-volume production.

[0088] Please refer to the appendix. Figure 4-6 The first clamping assembly 33 includes a first clamping block 331 horizontally disposed above the side of the second working plate 31 away from the third working plate 32. A second bracket 332 connected to the second working plate 31 is provided above the first clamping block 331. A third servo hydraulic cylinder 333 is provided on the second bracket 332 for driving the first clamping block 331 to move toward or away from the side of the second working plate 31. The side of the first clamping block 331 away from the third working plate 32 and the side of the second working plate 31 away from the third working plate 32 are on the same vertical plane.

[0089] The second clamping assembly 34 includes a second clamping block 341 horizontally disposed above the side of the third working plate 32 opposite to the second working plate 31. A third bracket 342 connected to the third working plate 32 is provided above the second clamping block 341. A fourth servo hydraulic cylinder 343 is provided on the third bracket 342 for driving the second clamping block 341 to move toward or away from the third working plate 32. The side of the second clamping block 341 opposite to the second working plate 31 and the side of the third working plate 32 opposite to the second working plate 31 are on the same vertical plane.

[0090] The second clamping block 341 has a horizontally aligned plate 344 frictionally engaged on the side opposite to the second working plate 31. The side of the aligned plate 344 near the second clamping block 341 has a first electromagnet. The second clamping assembly 34 also includes a Hall sensor for detecting whether the first electromagnet attracts an object. The third bracket 342 is provided with a fifth servo hydraulic cylinder 345 for moving the aligned plate 344 toward the side closer to or away from the third working plate 32, so that the aligned plate 344 is located between the second clamping block 341 and the third working plate 32.

[0091] A moving component 5 is provided above the second working plate 31. A receiving groove 32a is formed by a recess on the upper side of the third working 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 to the side of the plurality of second servo hydraulic cylinders 346 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 or be received into the receiving groove 32a. The conveying direction of the conveyor belt 347 is from the second working plate 31 to the third working plate 32.

[0092] A light sensor is installed on the conveyor belt 347 to detect whether there is a steel coil on the conveyor belt 347. If there is, the first servo hydraulic cylinder 54 of the moving component 5 located on the second working plate 31 retracts, causing the first servo hydraulic cylinder 54 to leave the steel coil. The second servo hydraulic cylinder 346 drives the conveyor belt 347 to extend out of the receiving groove 32a. At the same time, the conveyor belt 347 works to drive the steel coil to continue moving towards the side away from the second working plate 31 until the Hall sensor detects that the side of the steel coil away from the second working plate 31 contacts the first electromagnet and stops (Hall sensor detection principle: after adsorbing an item, the magnetic field around the electromagnet weakens. When the magnetic field is below the threshold, it indicates that the first electromagnet has adsorbed an item). At the same time, the second servo hydraulic cylinder 346 drives the conveyor belt 347 to descend and be received into the receiving groove 32a. The setting of the transmission belt can eliminate the clamping force on the movement of the steel coil, so that the side of the steel coil away from the second working plate 31 can be completely attached to the first electromagnet to complete the position correction of the steel coil.

[0093] After the steel coil enters the second working plate 31 at one end and the third working plate 32 at the other end, the third servo hydraulic cylinder 333 drives the first clamping block 331 to move towards the side closer to the second working plate 31, so that the first clamping block clamps the steel coil located on the second working plate 31; the fourth servo hydraulic cylinder 343 drives the second clamping block 341 to move towards the side closer to the third working plate 32, so that the second clamping block clamps the steel coil located on the third working plate 32.

[0094] After the first trimming assembly 35 and the second trimming assembly 36 perform the side trimming step on the steel coil, the second clamping plate and the first clamping plate move away from the steel coil.

[0095] After the second electromagnet 10 performs 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 component 5 located above the second working plate 31 descends to drive the steel coil to move towards the third working plate 32. At the same time, the transmission belt drives the steel coil to move towards the fourth working plate 41 until the steel coil enters the steel coil.

[0096] Hall effect sensor + electromagnet: detects the position of the steel coil and adsorbs it for correction, ensuring that the edge is aligned with the cutting shears (accuracy ±0.1mm); the conveyor belt descends at 347° to eliminate clamping force interference and prevent the plate from warping; the clamping block is aligned with the side of the working plate to protect the edge of the plate when clamping and prevent the high-strength steel from brittle cracking; the clamping → trimming → release → conveying are automatically linked, reducing manual intervention.

[0097] Please refer to the appendix. Figure 4-5 The first trimming assembly 35 includes a first servo slide 351 disposed on the side of the first clamping block 331 away from the third working plate 32. The slider of the first servo slide 351 is provided with a first connecting rod 352. One end of the first connecting rod 352 away from the slider of the first servo slide 351 is connected to a first cutting shear 353. The blade of the first cutting shear 353 is on the same vertical plane as the side of the first clamping block 331 away from the third working plate 32.

[0098] The second trimming assembly 36 includes a second servo slide 361 disposed on the side of the second clamping block 341 opposite to the second working plate 31. A second connecting rod 362 is provided on the slider of the second servo slide 361. A second cutting shear 363 is connected to one end of the second connecting rod 362 opposite to the slider of the second servo slide 361. The blade of the second cutting shear 363 is on the same vertical plane as the side of the second clamping block 341 opposite to the second working plate 31. After the first clamping block 331 and the second clamping block 341 clamp the steel coil, the first servo slide 351 drives the first cutting shear 353 to move along the side of the second working plate 31, so that the first cutting shear 353 cuts the portion of the steel coil extending from the second working plate 31, thereby trimming the rough edges of the steel coil extending from the second working plate 31. The second servo slide 361 drives the second cutting shear 363 to move along the side of the third working plate 32, so that the second cutting shear 363 cuts the portion of the steel coil extending from the third working plate 32, thereby trimming the rough edges of the steel coil extending from the third working plate 32. The cutting shear moves along the edge of the working plate to completely remove the rough edges of the protruding portion. The servo slide drives the cutting shear, and the travel path is parallel to the edge of the plate (error ≤ 0.05mm) to avoid uneven cuts.

[0099] Please refer to the appendix. Figure 2 and 4An adsorption plate 9 is vertically arranged between the second working plate 31 and the third working plate 32. The adsorption plate 9 is slidably mounted on the base plate 1. The sliding direction of the adsorption plate 9 is the same as the sliding direction of the first support column 6. A plurality of second electromagnets 10 are spaced apart on the side of the adsorption plate 9 away from the base plate 1. A plurality of spring shafts 11 are spaced apart on the side of the second working plate 31 near the third working plate 32. A steel strip 12 is wound on the spring shaft 11. The end of the steel strip 12 away from the spring shaft 11 is fixed to the upper side of the third working plate 32. A plurality of second electromagnets 10 are spaced apart between two steel strips 12. A first push rod 17 for pushing the adsorption plate 9 toward the third working plate 32 is horizontally arranged on the side of the first support column 6 near the third working plate 32. A second push rod 18 for pushing the adsorption plate 9 toward the second working plate 31 is horizontally arranged on the side of the second support column 7 near the second working plate 31. After the steel coil is aligned, the second electromagnet 10 attracts the steel coil, and the steel strip 12 bridges the gap between the working plates to prevent the plate from falling and getting stuck in the equipment (especially for thin-gauge high-strength steel). After the second and third clamping plates move away from the steel coil, the second electromagnet 10 is de-energized and stops attracting the tempered plate.

[0100] Please refer to the appendix. Figure 2 The second working plate 31 is provided with multiple first pillars 6 below it. Each first pillar 6 is slidably mounted on the base plate 1. The sliding direction of the first pillar 6 is the same as the extension direction of the base plate 1. The third working plate 32 is provided with multiple second pillars 7 below it. Each second pillar 7 is slidably mounted on the base plate 1. The sliding direction of the first pillar 6 and the second pillar 7 is the same.

[0101] The spacing adjustment assembly includes a sixth servo hydraulic cylinder 37 for moving the first support column 6 and a seventh servo hydraulic cylinder 38 for moving the second support column 7. After the second electromagnet 10 performs the step of adsorbing the steel coil, the sixth servo hydraulic cylinder 37 and the seventh servo hydraulic cylinder 38 work synchronously to bring the second working plate 31 and the third working plate 32 closer together, so that one end of the steel coil extends out of the second working plate 31 and the other end extends out of the third working plate 32, and the second working plate 31 and the third working plate 32 move the same distance. After the conveyor belt 347 performs the step of moving the steel coil away from the third working plate 32, the sixth servo hydraulic cylinder 37 and the seventh servo hydraulic cylinder 38 work synchronously to move the second working plate 31 and the third working plate 32 away from each other, thereby resetting the second working plate 31 and the third working plate 32 to facilitate the next step of cutting the steel coil.

[0102] The sixth servo hydraulic cylinder 37 and the seventh servo hydraulic cylinder 38 are also 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 accommodate steel coils of different sizes.

[0103] Please refer to the appendix. Figure 1-2 The material discharge assembly 4 includes a fourth working plate 41 located on the side of the third working plate 32 opposite to the second working plate 31. The fourth working plate 41 is equipped with the moving assembly 5. Multiple third support columns 8 are located below the fourth working plate 41. The third support columns 8 are slidably mounted on the base plate 1, and their sliding direction is the same as that of the second support columns 7. The material discharge assembly 4 also includes an eighth servo hydraulic cylinder 42 mounted on the base plate 1 to move the third support columns 8. The fourth working plate 41 receives the trimmed sheet material, and the moving assembly 5 removes it from the production line, forming a closed-loop production flow. The eighth servo hydraulic cylinder 42 adjusts the position of the third support columns 8 to adjust the position of the fourth working plate 41.

[0104] This invention also proposes a servo control method for a high-speed finishing flying shear for high-strength steel coils, employing any of the high-speed finishing flying shears described above.

Then control the second servo hydraulic cylinder 346 to descend so that the conveyor belt 347 is received into the receiving groove 32a.

[0107] S3: Controls the second electromagnet 10 to attract steel coils;

[0108] S4: Control the sixth servo hydraulic cylinder 37 to drive the first support column 6 to move, and simultaneously control the seventh servo hydraulic cylinder 38 to drive the second support column 7 to move, so that the distance between the second working plate 31 and the third working plate 32 is reduced to the target value, so that one end of the cut steel coil extends out of the second working plate 31 and the other end extends out of the third working plate 32.

[0109] S5: Control the third servo hydraulic cylinder 333 to drive the first clamping block 331 to clamp the steel coil on the second working plate 31, and at the same time control the fourth servo hydraulic cylinder 343 to drive the second clamping block 341 to clamp the steel coil on the third working plate 32.

[0110] S6: Control the first servo slide 351 to drive the first cutting shears 353 to move along the side of the second working plate 31 to cut the rough edges extending from the second working plate 31; Control the second servo slide 361 to drive the second cutting shears 363 to move along the side of the third working plate 32 to cut the rough edges extending from the third working plate 32.

[0111] S7: Control the first clamping block 331 and the second clamping block 341 to release the steel coil, and simultaneously control the second electromagnet 10 to release the steel coil;

[0112] S8: Control the sixth servo hydraulic cylinder 37 and the seventh servo hydraulic cylinder 38 to drive the second working plate 31 and the third working plate 32 to reset to the initial distance;

[0113] S9: The moving component 5 of the control discharge component 4 drives the active roller 53 to press the steel coil and drive the steel coil to move out of the trimming component 3.
