Description

Technical Field

[0001] The present invention relates to the technical field of cutting equipment, and more particularly to an automated strip cutting device for ship hull steel coils. Background Art

[0002] During the processing of ship hull steel coils, it is usually necessary to perform strip cutting and trimming operations. Strip cutting refers to the process of cutting a wide steel coil into strips of the width required by the customer. This step ensures that each cut strip of steel has a uniform width and excellent surface quality.

[0003] Chinese Patent CN202323089232.2 discloses an adjustable steel coil uncoiling and cutting device, which includes an operation frame. Guide plates are attached to both sides of the inner wall of the operation frame. First hydraulic push rods are fixedly installed at the four corners of the operation frame. One end of each first hydraulic push rod penetrates through the four corners of the operation frame and is fixedly installed with a cutting frame. One side of the cutting frame is slidably connected to one side of the guide plate. A placement groove is provided inside the cutting frame, and a right-angle cutting blade is provided in the placement groove; by lifting the cutting frame with the first hydraulic push rod, pushing the moving seat with the second hydraulic push rod, and moving the load-bearing frame along one side of the guide plate. When the load-bearing frame descends, the split coil axially approaches inward, and two adjacent circular blades clamp the transported steel coil.

[0026] 1. In the present invention, the first motor drives the first rotating shaft to rotate, causing the corresponding slip ring to rotate. The slip ring drives the movable contact plate to rotate synchronously by means of the sliding fit between the mounting groove and the movable contact plate. Under the action of centrifugal force, the movable contact plate slides to one end of the mounting groove away from the inner wall of the slip ring, and the first spring is stressed and elongated, so that the outer end of the movable contact plate abuts against the outer surface of the steel coil body, which is convenient for pressing both sides of the slitting position of the steel coil body during the slitting process of the steel coil body, improving the stability of slitting, avoiding the phenomenon of burrs on the side of the steel coil body after slitting, and at the same time, realizing the adjustability of the movable contact plate, which can meet the pressing requirements of the surfaces of steel coil bodies with different thicknesses;

[0027] 2. In the present invention, when the slitting width of the steel coil body needs to be reduced, the third rotating rod realizes the movement of the two sliding seats towards the middle of the third rotating rod through the sliding fit between the guiding groove group and the sliding seat and the sliding fit between the sliding seat and the supporting groove plate. The sliding seat drives the two slitting components to move towards the middle of the third rotating rod synchronously through the sliding fit between the second spring and the sliding arc groove and the sliding fit between the first engaging plate and the sliding arc groove. During the process of the sliding seat approaching the middle, the distance between two adjacent sliding seats always remains the same, which can realize the equal-spacing reduction of the distance between two adjacent slitting components, thereby realizing the reduction of the slitting width, meeting the cutting requirements of steel coil narrow strips with different sizes, avoiding the disadvantage that the slitting width of the existing device is fixed and inconvenient to adjust, solving the problem that different slitting devices are required to cut steel coil narrow strips with different widths, and improving the applicability of the device;

[0028] 3. In the present invention, through the cooperation of the conveying component and the centering component, the steel coil body can be stably centered and loaded, ensuring that the steel coil body will not deviate from the center of the device during the slitting process, avoiding affecting the slitting accuracy;

[0029] 4. In the present invention, through the lifting component, the height of the second rotating rod can be adjusted, so as to adjust the cutting depth of the slitting component, improving the slitting accuracy of the steel coil body. Through the cutting component, the corresponding position of the steel coil body can be cut, which can meet the winding process of the corresponding slitting length of the steel coil body in the subsequent process.

[0042] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0043] In one embodiment of the present invention, refer to Figures 1-4, an automated hull steel coil slitting and cutting device, including a support assembly 1. The support assembly 1 includes a base 101, and vertical frames 102 are symmetrically installed at both ends of the base 101. A support chute 103 is provided on the vertical frame 102.

The rotating assembly 2 includes a lifting seat 206 slidably arranged inside the support chute 103. A second rotating rod 207 is rotatably arranged between the two lifting seats 206. A first rotating rod 205 is rotatably arranged between the two vertical frames 102 and is located below the second rotating rod 207. The vertical frame 102 is provided with a first driving module connected to the lifting seat 206 and a second bevel gear ring 208. A plurality of slitting assemblies 3 for slitting the steel coil body 9 are distributed on both the first rotating rod 205 and the second rotating rod 207. An adjusting assembly 4 is provided between the vertical frames 102 and is matched with the slitting assembly 3. A cutting assembly 8 for cutting the steel coil body 9 is installed between the vertical frames 102. Conveying assemblies 5 are provided at both ends of the vertical frames 102 and are matched with the first rotating rod 205. A centering assembly 6 for abutting against both sides of the steel coil body 9 is installed on the vertical frame 102. A lifting assembly 7 connected to the lifting seat 206 is installed on the top of the vertical frame 102.

[0044] In this embodiment, through the cooperation of the conveying assembly 5 and the centering assembly 6, the steel coil body 9 can be centered and conveyed. Through the cooperation of the rotating assembly 2 and the slitting assembly 3, the steel coil body 9 can be subjected to equidistant slitting treatment. Through the adjusting assembly 4, the distance between adjacent two slitting assemblies 3 can be flexibly adjusted, which can meet the slitting requirements of different widths of the steel coil body 9 and avoid the problem that the distance between adjacent two slitting assemblies 3 is fixed and only steel strips of a fixed width can be cut. Through the lifting assembly 7, the height of the second rotating rod 207 can be adjusted, so as to adjust the cutting depth of the slitting assembly 3. Through the cutting assembly 8, the steel coil body 9 with a satisfied length can be cut, improving the practicability of the device, and having the effects of centering feeding, equidistant slitting, flexible distance adjustment, stable slitting, reliable structure, convenient operation and simple and practical.

[0045] Among them, the cutting assembly 8 includes a fixing plate 801 arranged on the upper part of the vertical frame 102 and a fixed knife bar 804 arranged on the lower part of the vertical frame 102. The fixing plate 801 and the fixed knife bar 804 are respectively located on the upper and lower sides of the steel coil body 9. A movable knife bar 803 is slidably arranged between the vertical frames 102 and is located between the fixing plate 801 and the steel coil body 9. A second electric cylinder 802 is connected between the fixing plate 801 and the movable knife bar 803;

[0046] In the initial state, the movable knife bar 803 is far from the upper surface of the steel coil body 9, and the second electric cylinder 802 is close to the lower surface of the steel coil body 9. When it is necessary to cut the corresponding length of the steel coil body 9, the second electric cylinder 802 extends downward and drives the movable knife bar 803 to move downward. The movable knife bar 803 cuts the corresponding position of the steel coil body 9 by cooperating with the fixed knife bar 804, which can meet the winding process of the corresponding strip length of the subsequent steel coil body 9.

[0047] In an embodiment of the present invention, refer to Figures 1-4 The first driving module includes a first motor 201 installed at the top of one of the vertical frames 102. The output end of the first motor 201 is connected to a first rotating shaft 202. The outer end of the first rotating shaft 202 is connected to a first bevel gear 203. The first bevel gear 203 meshes with a first bevel gear ring 204 arranged at the end of the first rotating rod 205. A second bevel gear 209 is rotatably arranged on the lifting seat 206. The second bevel gear 209 is sleeved outside the first rotating shaft 202 and is slidably matched with a guiding chute 2021 arranged on the first rotating shaft 202. The second bevel gear 209 meshes with a second bevel gear ring 208 arranged at the end of the second rotating rod 207.

[0048] In this embodiment, the first motor 201 drives the first rotating shaft 202 to rotate. The first rotating shaft 202 drives the first rotating rod 205 to rotate by meshing the first bevel gear 203 with the first bevel gear ring 204. At the same time, the first rotating shaft 202 drives the second rotating rod 207 to rotate reversely by the sliding fit of the guiding chute 2021 with the second bevel gear 209 and the meshing of the second bevel gear 209 with the second bevel gear ring 208. The first rotating rod 205 and the second rotating rod 207 perform strip cutting on the steel coil body 9 by driving the strip cutting assembly 3 arranged thereon to rotate respectively;

[0049] Among them, the first bevel gear 203 and the second bevel gear 209 have the same size, the first bevel gear ring 204 and the second bevel gear ring 208 have the same size, and the number of teeth of the first bevel gear 203 is less than the number of teeth of the first bevel gear ring 204.

[0050] In an embodiment of the present invention, refer to Figures 1-5, the strip dividing assembly 3 includes moving chutes 301 respectively arranged on the first rotating rod 205 and the second rotating rod 207. A number of sliding rings 302 that are slidably engaged with the moving chutes 301 are movably sleeved on both the first rotating rod 205 and the second rotating rod 207. A strip dividing cutter head 303 is installed on the outer side wall of the sliding ring 302. Sliding arc grooves 304 are provided at the outer edges of both ends of the sliding ring 302. A number of mounting grooves 305 are circumferentially distributed on both side walls of the sliding ring 302. An active abutting plate 306 is slidably arranged in the mounting groove 305. The outer end of the active abutting plate 306 is movably abutted against the surface of the steel coil body 9. A first spring 307 is connected between the mounting groove 305 and the active abutting plate 306.

[0051] In this embodiment, in the initial state, the first spring 307 is in its original length, and the active abutting plate 306 is located at one end of the mounting groove 305 close to the inner wall of the sliding ring 302. Through the adjusting assembly 4, the positions of a number of sliding rings 302 can be restricted. When strip dividing the steel coil body 9 is required, the first motor 201 drives the first rotating shaft 202 to rotate. The first rotating shaft 202 drives the first rotating rod 205 to rotate in a manner of meshing with the first bevel gear ring 204 through the first bevel gear 203. At the same time, the first rotating shaft 202 drives the second rotating rod 207 to rotate reversely in a manner of slidingly engaging with the second bevel gear 209 through the guiding chute 2021 and meshing the second bevel gear 209 with the second bevel gear ring 208. Both the first rotating rod 205 and the second rotating rod 207 drive the corresponding sliding rings 302 to rotate in a manner of slidably engaging with the sliding rings 302 through the moving chutes 301. The sliding rings 302 drive the active abutting plates 306 to rotate synchronously in a manner of slidably engaging with the active abutting plates 306 through the mounting grooves 305. The active abutting plates 306 slide to one end of the mounting groove 305 away from the inner wall of the sliding ring 302 under the action of centrifugal force. The first spring 307 is stressed and elongated, so that the outer end of the active abutting plate 306 abuts against the surface of the steel coil body 9, which is convenient for pressing both sides of the strip dividing position of the steel coil body 9 during the strip dividing process of the steel coil body 9, improving the stability of strip dividing and avoiding the phenomenon of burrs appearing on the side edges of the steel coil body 9 after strip dividing;

[0052] When the strip dividing of the steel coil body 9 is completed, the first motor 201 stops working, the active abutting plates 306 stop rotating, and the active abutting plates 306 slide towards one end of the mounting groove 305 close to the inner wall of the sliding ring 302 under the pulling force of the first spring 307, realizing the contraction of the active abutting plates 306, and realizing the adjustability of the active abutting plates 306, which can meet the pressing requirements for the surfaces of steel coil bodies 9 with different thicknesses.

[0053] In an embodiment of the present invention, see Figures 1-2 、 Figures 5-7, the adjusting assembly 4 includes third rotating rods 405 respectively rotatably arranged at the bottom and top of the vertical frame 102. The third rotating rods 405 are distributed with a guiding groove group 406. The guiding groove group 406 includes an annular groove 4061 and a plurality of spiral sliding grooves 4062. The annular groove 4061 is arranged in the middle of the third rotating rod 405. The plurality of spiral sliding grooves 4062 are evenly and divergently distributed on both sides of the annular groove 4061, and one end close to the annular groove 4061 is in a converging shape. A plurality of sliding seats 407 slidably matched with the supporting groove plate 104 are movably sleeved on both third rotating rods 405. A sliding column 413 slidably matched with the corresponding guiding groove group 406 is arranged on the inner wall of the sliding seat 407. A first clamping plate 408 slidably matched with the corresponding sliding arc groove 304 is arranged on the sliding seat 407 located below. Side ears 409 are arranged on both side walls of the sliding seat 407 located above. A connecting pin 410 is slidably arranged in the side ears 409. The bottoms of the two connecting pins 410 are connected by a second clamping plate 411. The second clamping plate 411 is slidably matched with the corresponding sliding arc groove 304. A second spring 412 sleeved on the outer side of the connecting pin 410 is connected between the side ears 409 and the second clamping plate 411. A second driving module connected to the two third rotating rods 405 is arranged on the outer wall of the vertical frame 102;

[0054] The second driving module includes a second motor 401 installed at the top of the vertical frame 102. The output end of the second motor 401 is connected with a second rotating shaft 402. Two third bevel gears 403 are arranged on the second rotating shaft 402. Fourth bevel gears 404 meshing with the corresponding third bevel gears 403 are arranged at the ends of the two third rotating rods 405.

[0055] In this embodiment, in the initial state, the distance between adjacent two sliding seats 407 is at the maximum value. At this time, the distance between adjacent two strip dividing assemblies 3 is at the maximum value. The first motor 201 drives the first rotating shaft 202 to rotate. The first rotating shaft 202 drives the first rotating rod 205 to rotate by the way of meshing the first bevel gear 203 with the first bevel gear ring 204. At the same time, the first rotating shaft 202 drives the second rotating rod 207 to rotate reversely by the way of the guiding sliding groove 2021 slidingly matching with the second bevel gear 209 and the second bevel gear 209 meshing with the second bevel gear ring 208. Both the first rotating rod 205 and the second rotating rod 207 drive the corresponding strip dividing assemblies 3 to rotate by the way of slidingly matching the moving sliding groove 301 with the sliding ring 302, and the steel coil body 9 can be strip-divided;

[0056] When the slitting width of the steel coil body 9 needs to be reduced, the second motor 401 drives the second rotating shaft 402 to rotate. The second rotating shaft 402 drives two third bevel gears 403 to rotate synchronously. The third bevel gears 403 drive the corresponding third rotating rods 405 to rotate by meshing with the fourth bevel gears 404. The third rotating rods 405 realize the sliding seats 407 on both sides approaching the middle of the third rotating rods 405 through the sliding fit of the guiding groove groups 406 with the sliding seats 407 and the sliding fit of the sliding seats 407 with the supporting groove plates 104. The sliding seats 407 drive the slitting assemblies 3 on both sides to move towards the middle of the third rotating rods 405 through the sliding fit of the second springs 412 with the sliding arc grooves 304 and the sliding fit of the first engaging plates 408 with the sliding arc grooves 304. During the process of the sliding seats 407 approaching the middle, the distance between two adjacent sliding seats 407 always remains the same, which can realize the equal-spacing reduction of the distance between two adjacent slitting assemblies 3, thereby realizing the reduction of the slitting width, avoiding the disadvantage that the slitting width of the existing device is fixed and inconvenient to adjust, and solving the problem that different slitting devices are required to cut narrow strips of steel coils with different widths;

[0057] Among them, through the sliding connection of the side ears 409 and the connecting pins 410 and the elastic connection of the second springs 412, the second engaging plates 411 can always maintain a sliding fit with the corresponding sliding arc grooves 304, avoiding the problem that the second engaging plates 411 cannot cooperate with the sliding arc grooves 304 after the height of the corresponding sliding rings 302 is adjusted, and improving the stability of slitting;

[0058] The spiral angles of several spiral chute 4062 are the same, and the connection lines between the corresponding ends of several spiral chute 4062 are parallel to the axis of the third rotating rod 405.

[0059] In an embodiment of the present invention, refer to Figures 1-3 and Figure 6 , the conveying assembly 5 includes side frames 501 symmetrically arranged on the two side walls of the vertical frame 102. A conveying roller 502 is rotatably connected between the corresponding side frames 501 on the two vertical frames 102. A first belt pulley 503 is arranged at the end of the conveying roller 502. A second belt pulley 505 is arranged at the end of the first rotating rod 205. The second belt pulley 505 and the two first belt pulleys 503 are connected by a transmission belt 504.

[0060] In this embodiment, the first motor 201 drives the first rotating shaft 202 to rotate. The first rotating shaft 202 drives the first rotating rod 205 to rotate by meshing with the first bevel gear ring 204 through the first bevel gear 203. The first rotating rod 205 drives the second pulley 505 to rotate synchronously. The second pulley 505 drives the first pulley 503 to rotate synchronously by connecting with the transmission belt 504. The first pulley 503 realizes the loading process of the steel coil body 9 by driving the conveying roller 502 to rotate synchronously, which is convenient for the strip loading and discharging of the steel coil body 9 and the strip processing of the steel coil body 9.

[0061] In one embodiment of the present invention, refer to Figure 1 、 Figure 3 and Figure 8 The centering assembly 6 includes a mounting frame 601 provided at the bottom of the two vertical frames 102. A bidirectional lead screw 603 is rotatably provided in the mounting frame 601. The end of the bidirectional lead screw 603 is connected to a third motor 602 mounted on the outer wall of the mounting frame 601. Symmetrically and slidably provided in the mounting frame 601 are threaded sliders 604. The threaded sliders 604 are in threaded cooperation with the bidirectional lead screw 603. The top of the threaded slider 604 is rotatably connected to a contact roller 605 that abuts against the two sides of the steel coil body 9.

[0062] In this embodiment, in the initial state, the symmetrically arranged threaded sliders 604 are far away from each other. At this time, the distance between the two contact rollers 605 is at the maximum value. When loading the steel coil body 9 through the conveying assembly 5, according to the actual width of the steel coil body 9, the third motor 602 is controlled to work. The third motor 602 drives the bidirectional lead screw 603 to rotate. The bidirectional lead screw 603 drives the two threaded sliders 604 to approach each other by means of threaded connection with the threaded sliders 604 and the sliding fit of the threaded sliders 604 with the mounting frame 601. The threaded sliders 604 abut against the two sides of the steel coil body 9 by driving the contact rollers 605 to move synchronously, which is convenient for centering the steel coil body 9. Through the cooperation of the rotating conveying roller 502 and the contact rollers 605 located on both sides of the steel coil body 9, the steel coil body 9 can be stably centered and loaded, ensuring that the steel coil body 9 will not deviate from the center of the device during the strip cutting process and avoiding affecting the strip cutting accuracy.

[0063] In one embodiment of the present invention, refer to Figures 1-3 The lifting assembly 7 includes a lifting frame 702 movably provided at the bottom of the vertical frame 102. At both ends of the lifting frame 702, symmetrically arranged connecting rods 703 are provided, which penetrate through the vertical frame 102 and are connected to the corresponding lifting seats 206. An electric cylinder 701 is connected between the lifting frame 702 and the support groove plate 104 located at the top of the vertical frame 102.

[0064] In this embodiment, according to the actual cutting pressure requirement, the electric cylinder 701 adjusts the height of the lifting frame 702 by telescoping. The lifting frame 702 drives the corresponding lifting seat 206 to lift synchronously by connecting with the connecting rod 703 and the sliding fit between the connecting rod 703 and the vertical frame 102. The lifting seat 206 drives the corresponding slitting assembly 3 to lift synchronously by the rotational fit with the second rotating rod 207, so as to adjust the cutting depth of the slitting assembly 3 and improve the slitting accuracy of the steel coil body 9.

[0065] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
