Description

Technical Field

[0001] The present invention relates to the technical field of steel coil cutting, in particular to a steel coil cutting machine and method. Background Art

[0002] As an important metal material, steel coils are widely used in many fields such as construction, automobile manufacturing, mechanical processing, and electronic equipment. In the actual application of steel coils, they often need to be cut into fragments of specific sizes and shapes according to different production requirements. Therefore, steel coil cutting machines have become an indispensable key equipment in the steel processing process. The quality of their performance directly affects the quality, efficiency, and production cost of steel processing.

[0003] At present, there are many types of steel coil cutting machines on the market, the most common ones are flame cutting machines, plasma cutting machines, laser cutting machines and mechanical cutting machines. Different types of cutting machines have their own characteristics in terms of cutting principles, scope of application, cutting accuracy and cost. During the transportation and storage of existing steel coils, their surfaces are prone to wrinkles, bends and other unevenness. However, most of the existing steel coil cutting machines lack effective steel coil smoothing devices, or the functions of the smoothing devices are not perfect. When cutting uneven steel coils, due to the uneven thickness and irregular shape of various parts of the steel, the resistance encountered during the cutting process is unevenly distributed, which will cause the movement of the cutter and the cutting base to be unstable, and easily produce additional displacement or deformation, resulting in inaccurate cutting dimensions, uneven incisions and other problems, and cannot meet the strict requirements of the product on dimensional accuracy, increasing the scrap rate and increasing production costs. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the present invention provides a steel coil cutting machine and method, which solve the technical problems mentioned in the background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: A steel coil cutting machine includes a frame, a steel coil is provided on one side of the frame, a fixing plate fixedly mounted on the frame is provided on one side of the steel coil, and a cutting assembly for cutting the steel coil is provided between the two fixing plates;

[0006] The cutting assembly includes a first rotating shaft and a second rotating shaft rotatably mounted on the upper and lower ends of both sides of the fixed plate, and transmission parts are provided at the ends of the first rotating shaft and the second rotating shaft. Mounting brackets are provided on the inner sides of the two transmission parts. A cutter is fixedly mounted between the two upper mounting brackets, and a cutting base is fixedly mounted between the two lower mounting brackets. The cutter and the cutting base are adapted for cutting.

[0007] As a further preferred embodiment of the present technical solution, the transmission member includes a connecting rod installed on the first rotating shaft and the second rotating shaft, the outer walls of the two first rotating shafts are fixedly connected with mutually meshing gears, and the outer end of the upper first rotating shaft is provided with a driving motor fixedly installed on a fixed plate, the inner ends of the first rotating shaft and the second rotating shaft are fixedly connected with rotating rods, and the other ends of the two rotating rods are rotatably connected to the mounting frame.

[0008] As a further preferred embodiment of the present technical solution, a cutting groove is provided on the upper surface of the cutting base, and the cutting knife and the cutting groove are adapted to each other.

[0009] As a further preference of the present technical solution, smoothing parts are provided on both sides of the cutter, and the smoothing parts include a fixed frame fixedly installed on the upper and lower ends of the fixed plate, a telescopic frame is provided on the fixed frame, a fixed frame is provided at the inner end of the telescopic frame, and the opposite ends of the two fixed frames are rotatably connected to a smoothing rod through a torsion spring.

[0010] As a further optimization of the present technical solution, reciprocating screws are rotatably connected to both sides of the outer wall of the fixed plate, the outer wall of the reciprocating screw is threadedly connected to the adjustment plate, and the two ends of the adjustment plate are fixedly connected to moving rods, the moving rods are slidably installed on the fixed plate, and the other end of the moving rods is fixedly connected to the horizontal plate.

[0011] As a further preferred embodiment of the present technical solution, the two reciprocating screws are connected in transmission via a first synchronous pulley transmission member, and one of the reciprocating screws is connected in transmission to the first rotating shaft at a lower position via a second synchronous pulley transmission member.

[0012] As a further optimization of this technical solution, one end of the steel coil passes through the smoothing piece, the cutter and the cutting base. After the smoothing piece located on both sides of the cutter and the cutting base smoothes the steel coil, the cutter is used in conjunction with the cutting base to cut the steel coil.

[0013] The present invention also discloses a cutting method of a steel coil cutting machine, which specifically comprises the following steps:

[0014] Step 1: Start the drive and transmission, and prepare for the smoothing action

[0015] Turn on the drive motor, which drives the first rotating shaft to rotate synchronously. The first rotating shaft uses the meshing gears to make the other first rotating shaft rotate in the opposite direction. At the same time, when the first rotating shaft at the lower position rotates, the reciprocating screw is driven to rotate synchronously through the second synchronous pulley transmission component. The reciprocating screw then drives the two reciprocating screws to operate synchronously through the first synchronous pulley transmission component, preparing for the subsequent smoothing of the steel coil.

[0016] Step 2: Smooth the steel coil and optimize cutting conditions

[0017] The reciprocating screw rotates to drive the adjustment plate to move outward from the fixed plate. The adjustment plate pushes the fixed plate, causing the two moving rods to move outward. The moving rods drive the horizontal plate and smoothing rods in the middle position to expand to both sides, while driving the telescopic frame to retract. The smoothing rods smooth the steel coils during the outward movement, eliminating wrinkles and unevenness on the surface of the steel coils, creating good conditions for subsequent precise cutting.

[0018] Step 3: The cutter and base cooperate to complete the cutting operation

[0019] After the smoothing work is completed, the first rotating shaft continues to rotate, and the mounting frame is driven to rotate back and forth through the second rotating shaft and the rotating rod. The two mounting frames present an elliptical motion trajectory, and the upper mounting frame rotates counterclockwise and the lower mounting frame rotates clockwise. The mounting frame drives the cutter and the cutting base to rotate back and forth. When the cutter and the cutting base rotate inward at the same time, the cutter cooperates with the cutting base to cut the smoothed steel coil; after the cutting is completed, the cutter and the cutting base rotate outward and separate at the same time to remove the cut steel coil and proceed with the next cutting.

[0020] Compared with the existing technology, it has the following beneficial effects:

[0021] By turning on the drive motor to drive the first rotating shaft to rotate synchronously, and then realizing the reverse rotation of the other first rotating shaft through the mutually meshing gears, the mounting frame is driven to rotate back and forth through the second rotating shaft and the rotating rod, and finally the cutter cooperates with the cutting base to cut the steel coil. This transmission structure design enables the cutting action to be carried out in an orderly and stable manner, thereby improving the cutting efficiency. The motion trajectories of the two mounting frames are elliptical, and the upper mounting frame rotates counterclockwise and the lower mounting frame rotates clockwise. This specific rotation method enables the cutter and the cutting base to cooperate accurately when they rotate inward at the same time, thereby realizing effective cutting of the steel coil and ensuring the cutting quality. When the cutter and the cutting base rotate outward at the same time, the cutter is separated from the cutting base. At this time, the cut steel coil can be easily removed and then the next cutting process can be carried out. This design is conducive to continuous operation, reducing downtime and improving overall production efficiency.

[0022] The movement of the adjusting plate drives the fixed plate to move the two moving rods outward, thereby allowing the cross plate and the smoothing rod to expand to both sides. The smoothing rod smoothes the steel coil in the process of moving outward, which can effectively eliminate the wrinkles, bends and other unevenness on the surface of the steel coil, making the steel coil in a flat state, providing a good foundation for the subsequent precise cutting of the cutter and the cutting base, greatly improving the cutting quality, and reducing the problems of cutting deviation and uneven incision caused by the unevenness of the steel coil; the thickness of each part of the smoothed steel coil is uniform and the shape is regular. When the cutter and the cutting base are close to each other for cutting, they can be cut more accurately according to the predetermined size, because after the steel coil is flat, the cutting process is smooth. The resistance encountered during the cutting process is more evenly distributed, the movement of the cutter and the cutting base is more stable, and there will be no additional displacement or deformation due to the unevenness of the steel coil, thereby ensuring the accuracy of the cutting size and meeting the strict size requirements of the product; the smoothing rod can be flexibly adjusted according to the width and shape of the steel coil, and the reciprocating screw drives the adjustment plate, moving rod and other components to move, thereby changing the position and deployment range of the smoothing rod, so that it can adapt to steel coils of different widths and specifications. No matter whether it is a narrow or wide steel coil, this structure can achieve effective smoothing of the steel coil by adjusting the position of the smoothing rod, thereby enhancing the adaptability of the equipment to steel coils of different specifications and expanding the scope of use of the equipment.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Example 1: Combination Figures 1-8 As shown, the present invention provides a technical solution: a steel coil cutting machine, comprising a frame 1, a steel coil 2 is placed on one side of the frame 1, and a fixed plate 3 is fixedly mounted on the frame 1 on one side of the steel coil 2, and a cutting assembly 4 specifically used for cutting the steel coil 2 is provided between the two fixed plates 3. The structure of the cutting assembly 4 is relatively complex, and it comprises two first rotating shafts 41 and a second rotating shaft 42 rotatably mounted on the upper and lower ends of both sides of the fixed plate 3, the ends of the two rotating shafts are provided with transmission members, and mounting brackets 47 are installed on the inner sides of the two transmission members, a cutter 48 is fixedly mounted between the upper two mounting brackets 47, and a cutting base 49 is fixedly mounted between the lower two mounting brackets 47, the cutter 48 and the cutting base 49 can achieve cutting adaptation, a cutting groove is provided on the upper surface of the cutting base 49, and the cutter 48 and the cutting groove are adapted to each other;

[0034] The specific structure of the transmission member includes a connecting rod 45 installed on the first rotating shaft 41 and the second rotating shaft 42, and the outer walls of the two first rotating shafts 41 are fixedly connected with mutually meshing gears 44. At the outer end of the upper first rotating shaft 41, a driving motor 43 fixedly installed on the fixed plate 3 is provided. The inner ends of the first rotating shaft 41 and the second rotating shaft 42 are fixedly connected with a rotating rod 46. The other ends of the two rotating rods 46 are rotationally connected with the mounting bracket 47. By turning on the driving motor 43, the first rotating shaft 41 can be driven to rotate synchronously, and the first rotating shaft 41 drives the other first rotating shaft 41 to rotate in the opposite direction through the mutually meshing gears 44. In this way, when the first rotating shaft 41 rotates, the mounting bracket 47 is driven to rotate back and forth through the linkage action of the second rotating shaft 42 and the rotating rod 46. The motion trajectory of the two mounting brackets 47 is elliptical, as shown specifically in FIG. Figure 2 As shown, the upper mounting bracket 47 rotates counterclockwise, while the lower mounting bracket 47 rotates clockwise. This design enables the mounting bracket 47 to drive the cutter 48 and the cutting base 49 to rotate back and forth. When the cutter 48 and the cutting base 49 rotate inward at the same time, the cutter 48 cooperates with the cutting base 49 to accurately cut the steel coil 2. When the cutter 48 and the cutting base 49 rotate outward at the same time, the cutter 48 separates from the cutting base 49, so that the cut steel coil 2 can be removed for the next cutting process. The entire cutting process is efficient and accurate, and can meet the high requirements for steel coil cutting in production.

[0035] A smoothing member 410 is provided on both sides of the cutter 48. The smoothing member 410 includes a fixed frame 411 fixedly mounted on the upper and lower ends of the fixed plate 3. A telescopic frame 412 is provided on the fixed frame 411. The inner end of the telescopic frame 412 is provided with a fixed frame 411, and the opposite ends of the two fixed frames 411 are rotatably connected to a smoothing rod 415 through a torsion spring; a reciprocating screw rod 416 is rotatably connected to the outer wall of the fixed plate 3, and an adjusting plate 417 is threadedly connected to the outer wall of the reciprocating screw rod 416, and the two ends of the adjusting plate 417 are fixedly connected to the moving rod 413 , the moving rod 413 is slidably mounted on the fixed plate 3, and the other end of the moving rod 413 is fixedly connected to the cross plate 414; the two reciprocating screw rods 416 are connected by a first synchronous pulley transmission member 418, and one of the reciprocating screw rods 416 is connected by a second synchronous pulley transmission member 419 to the first rotating shaft 41 at the lower position; one end of the steel coil 2 passes through the smoothing member 410, the cutter 48 and the cutting base 49, and the smoothing members 410 on both sides of the cutter 48 and the cutting base 49 smooth the steel coil 2 After processing, the steel coil 2 is cut by the cutter 48 in cooperation with the cutting base 49. Before the two first rotating shafts 41 drive the cutter 48 and the cutting base 49 to approach each other, the first rotating shaft 41 at the lower position drives the reciprocating screw rod 416 to rotate synchronously through the second synchronous belt pulley transmission member 419, and the reciprocating screw rod 416 drives the two reciprocating screw rods 416 to rotate synchronously through the first synchronous belt pulley transmission member 418, so that the reciprocating screw rod 416 can drive the adjusting plate 417 to the fixed plate 3 when rotating. The outward movement causes the fixed plate 3 to drive the two moving rods 413 to move outward, so that the moving rod 413 drives the horizontal plate 414 and the smoothing rod 415 located in the middle position to move to both sides, and drives the telescopic frame 412 to retract, so that the smoothing rod 415 can smooth the steel coil 2 during the process of moving outward, thereby facilitating the subsequent cutting of the steel coil 2; after the smoothing work is completed, the first rotating shaft 41 drives the cutter 48 and the cutting base 49 to approach each other and cut the steel coil 2.

[0036] In the embodiment of the present invention, the driving motor 43 is turned on to drive the first rotating shaft 41 to rotate synchronously, and the first rotating shaft 41 drives the other first rotating shaft 41 to rotate in the opposite direction through the mutually meshing gears 44, so that the first rotating shaft 41 drives the mounting bracket 47 to rotate back and forth through the second rotating shaft 42 and the rotating rod 46 when rotating. The motion trajectories of the two mounting brackets 47 are elliptical, and as shown in FIG. Figure 2As shown, the upper mounting bracket 47 rotates counterclockwise, while the lower mounting bracket 47 rotates clockwise, so that the mounting bracket 47 drives the cutter 48 and the cutting base 49 to rotate back and forth. When the cutter 48 and the cutting base 49 rotate inward at the same time, the cutter 48 cooperates with the cutting base 49 to cut the steel coil 2. When the cutter 48 and the cutting base 49 rotate outward at the same time, the cutter 48 separates from the cutting base 49, and the cut steel coil 2 can be removed for the next cutting process.

[0037] By turning on the drive motor 43 to drive the first rotating shaft 41 to rotate synchronously, and then the other first rotating shaft 41 is realized to rotate in the opposite direction through the mutually meshing gears 44, and then the second rotating shaft 42 and the rotating rod 46 drive the mounting frame 47 to rotate back and forth, and finally the cutter 48 cooperates with the cutting base 49 to cut the steel coil 2. This transmission structure design makes the cutting action orderly and stable, thereby improving the cutting efficiency. The movement trajectories of the two mounting frames 47 are elliptical, and the upper mounting frame 47 rotates counterclockwise and the lower mounting frame 47 rotates clockwise. This specific rotation method makes the cutter 48 and the cutting base 49 accurately cooperate when they rotate inward at the same time, so as to achieve effective cutting of the steel coil 2 and ensure the cutting quality. When the cutter 48 and the cutting base 49 rotate outward at the same time, the cutter 48 is separated from the cutting base 49. At this time, the cut steel coil 2 can be easily removed, and then the next cutting process can be carried out. This design is conducive to achieving continuous operation, reducing downtime, and improving overall production efficiency.

[0038] Before the two first rotating shafts 41 drive the cutter 48 and the cutting base 49 to approach each other, the first rotating shaft 41 located at the lower position drives the reciprocating screw rod 416 to rotate synchronously through the second synchronous belt pulley transmission member 419 when it rotates, and the reciprocating screw rod 416 drives the two reciprocating screw rods 416 to rotate synchronously through the first synchronous belt pulley transmission member 418, so that the reciprocating screw rod 416 can drive the adjustment plate 417 to move toward the outside of the fixed plate 3 when it rotates, so that the fixed plate 3 drives the two moving rods 413 to move outward, so that the moving rod 413 drives the horizontal plate 414 and the smoothing rod 415 located in the middle position to move to both sides, and drives the telescopic frame 412 to retract, so that the smoothing rod 415 can smooth the steel coil 2 during the process of moving outward, thereby facilitating the subsequent cutting of the steel coil 2; after the smoothing work is completed, the first rotating shaft 41 drives the cutter 48 and the cutting base 49 to approach each other and cut the steel coil 2;

[0039] The movement of the adjusting plate 417 drives the fixed plate 3 to move the two moving rods 413 outward, thereby allowing the cross plate 414 and the smoothing rod 415 to expand to both sides. The smoothing rod 415 smoothes the steel coil 2 during the outward movement, which can effectively eliminate the wrinkles, bends and other unevenness on the surface of the steel coil 2, so that the steel coil 2 is in a flat state, providing a good foundation for the subsequent precise cutting of the cutter 48 and the cutting base 49, greatly improving the cutting quality, and reducing the cutting deviation and uneven incision caused by the unevenness of the steel coil 2; after the smoothing, the thickness of each part of the steel coil 2 is uniform and the shape is regular. When the cutter 48 and the cutting base 49 are close to each other for cutting, they can be cut more accurately according to the predetermined size, because after the steel coil 2 is flat, the cutting The resistance encountered during the process is more evenly distributed, the movement of the cutter 48 and the cutting base 49 is more stable, and no additional displacement or deformation will occur due to the unevenness of the steel coil 2, thereby ensuring the accuracy of the cutting size and meeting the strict size requirements of the product; the smoothing rod 415 can be flexibly adjusted according to the width and shape of the steel coil 2, and the reciprocating screw 416 drives the adjustment plate 417, the moving rod 413 and other components to move, thereby changing the position and expansion range of the smoothing rod 415, so that it can adapt to steel coils 2 of different widths and specifications. Regardless of whether it is a narrower or wider steel coil 2, this structure can achieve effective smoothing of the steel coil 2 by adjusting the position of the smoothing rod 415, thereby enhancing the adaptability of the equipment to steel coils 2 of different specifications and expanding the scope of application of the equipment.

[0040] The present invention also discloses a cutting method of a steel coil cutting machine, which specifically comprises the following steps:

[0041] Step 1: Start the drive and transmission, and prepare for the smoothing action

[0042] The driving motor 43 is turned on, and the driving motor 43 drives the first rotating shaft 41 to rotate synchronously. The first rotating shaft 41 causes the other first rotating shaft 41 to rotate in the opposite direction by means of the mutually meshing gears 44. At the same time, when the first rotating shaft 41 at the lower position rotates, the reciprocating screw rod 416 is driven to rotate synchronously through the second synchronous belt pulley transmission member 419. The reciprocating screw rod 416 then drives the two reciprocating screw rods 416 to rotate synchronously through the first synchronous belt pulley transmission member 418, preparing for the subsequent smoothing of the steel coil 2.

[0043] Step 2: Smooth the steel coil and optimize cutting conditions

[0044] The reciprocating screw 416 rotates to drive the adjustment plate 417 to move outward from the fixed plate 3. The adjustment plate 417 pushes the fixed plate 3, causing the two moving rods 413 to move outward. The moving rods 413 drive the horizontal plate 414 and the smoothing rod 415 located in the middle position to expand to both sides, while driving the telescopic frame 412 to retract. The smoothing rods 415 smooth the steel coil 2 during the outward movement, eliminating wrinkles and unevenness on the surface of the steel coil 2, creating good conditions for subsequent precise cutting.

[0045] Step 3: The cutter and base cooperate to complete the cutting operation

[0046] After the smoothing work is completed, the first rotating shaft 41 continues to rotate, and drives the mounting frame 47 to rotate back and forth through the second rotating shaft 42 and the rotating rod 46. The two mounting frames 47 have an elliptical motion trajectory, and the upper mounting frame 47 rotates counterclockwise and the lower mounting frame 47 rotates clockwise. The mounting frame 47 drives the cutter 48 and the cutting base 49 to rotate back and forth. When the cutter 48 and the cutting base 49 rotate inward at the same time, the cutter 48 cooperates with the cutting base 49 to cut the smoothed steel coil 2; after the cutting is completed, the cutter 48 and the cutting base 49 rotate outward at the same time to separate so as to remove the cut steel coil 2 and perform the next cutting.
