Description

Technical Field

[0001] The present invention relates to the field of forming processes, and particularly to a steel strip rolling and forming device. Background Art

[0002] Rolling and forming is a forming process, and its working principle mainly utilizes the rotational movement of the rolling head and the extrusion force on the material. During the rolling process, the material is placed in the space between the rolling head and the mold. As the rolling head rotates, its contact surface squeezes the material, causing the material to undergo plastic deformation under the action of the extrusion force.

[0003] The rolling and forming device for steel strips generally includes a flattening device for extracting the steel strip from the coiled state and flattening it, a rolling device for rolling the steel strip into a specific shape, and a cutting mechanism for cutting the rolled and formed steel strip. In the prior art, after the steel strip is rolled and formed, it is directly conveyed to the cutting mechanism for cutting. During the process that the blade of the cutting mechanism cuts from one side of the steel strip to the other side, the blade easily drives the steel strip to undergo horizontal displacement. Affected by the displacement of the steel strip, during the process of the rolling device rolling the steel strip, there is a possibility that the steel strip is pressed crooked and deformed. Summary of the Invention

[0004] In order to solve the problem that the steel strip is prone to displacement, resulting in being pressed crooked and deformed, the present invention provides a steel strip rolling and forming device.

[0005] A steel strip rolling and forming device provided by the present invention adopts the following technical solutions:

[0006] A steel strip rolling and forming device includes a workbench, a flattening device installed on the workbench and used for flattening the steel strip from the coiled state, a rolling device installed on the workbench and used for rolling the flattened steel strip, and a cutting device installed on the workbench and used for cutting the rolled and formed steel strip. It further includes a front pressing mechanism and a rear pressing mechanism for pressing the steel strip against the workbench. The front pressing mechanism is installed on the workbench and is located between the rolling device and the cutting device. The rear pressing mechanism is installed on the workbench and is located on the side of the cutting device far from the rolling device; the cutting device includes:

[0007] A cutting machine for cutting the steel strip;

[0008] A mounting seat for horizontally slidingly mounting the cutting machine;

[0009] A vertical guide rail vertically installed on the workbench and used for vertically slidingly mounting the mounting seat;

[0010] A driving motor installed on the workbench and used for driving the blade of the cutting machine to move along a set route;

[0011] The workbench is provided with a receiving cavity, and the cutting mechanism is located in the receiving cavity; the workbench is provided with a cutting opening for the blade of the cutting machine to rotate and extend out and communicate with the receiving cavity;

[0012] The output shaft of the driving motor is fixedly connected with a driving plate, and a traction block is slidably mounted on the driving plate; the driving plate is threadedly connected with a driving screw for driving the traction block to slide, and the driving screw is threadedly connected to the traction block;

[0013] The traction block is coaxially rotatably connected with the blade of the cutting machine;

[0014] The driving motor drives the driving plate to swing left and right in a vertical plane, and the swing circumferential angle of the driving plate is 120° to 180°; the workbench is provided with an abutting table on the inner bottom surface of the receiving cavity, and the driving plate abuts against the top of the abutting table when rotating to the left and right ends respectively.

[0015] By adopting the above technical solution, when the steel strip is roll-formed and passes through the cutting device, the front pressing mechanism and the rear pressing mechanism can respectively press the steel strip on both sides of the cutting mechanism, so that the steel strip can be positioned.

[0016] The cutting machine is horizontally slidably mounted on the mounting seat, and at the same time the mounting seat is vertically slidably mounted on the vertical guide rail, and the cutting machine is moved by the driving motor. The cutting machine can move along the moving track of the traction block, so as to realize the left and right reciprocating swing cutting motion. Compared with the traditional unidirectional cutting method, that is, the cutting machine cuts from one side specified by the steel strip to the other side, by adopting the above-mentioned reciprocating cutting method of the cutting machine, that is, the cutting machine cuts from one side of the steel strip to the other side, and then continues to cut the next steel strip from the other side of the steel strip, the cutting machine can adjust the horizontal displacement of the steel strip during the cutting process of the steel strip. When the steel strip deviates from the original position, the blade of the cutting machine will reset the steel strip during the cutting process, so that the steel strip always remains in the initial position, is not easy to cut skew, and has little influence on the roll-forming step in the previous step and is not easy to be pressed skew and deformed.

[0017] And because the position of the traction block on the driving plate is adjustable, the cutting range of the cutting machine can be adjusted, and the cutting device can be applicable to steel strips of different width sizes, which is more practical.

[0018] Optionally, the mounting seat internally has a water passing cavity for the cleaning water to flow through, and both ends of the mounting seat have an inlet and an outlet for the cleaning water to flow in and out; a spray head is arranged at the bottom of the mounting seat, the spray head is communicated with the water passing cavity, and the spray head is directly opposite to the blade of the cutting machine;

[0019] A pressure sensor is provided on the vertical guide rail. When the mounting seat slides vertically and abuts against the pressure sensor, the nozzle sprays water on the blade of the cutting machine.

[0020] A return port is provided on the side wall of the workbench, which penetrates through to the accommodation cavity and is used for the cleaning water to flow out.

[0021] By adopting the above technical solution, when the cutting machine swings back and forth left and right and is at the left and right ends, the cutting machine is located in the accommodation cavity, and the mounting seat abuts against the pressure sensor. At this time, the nozzle on the mounting seat can clean the blade of the cutting machine, cool the blade and remove the debris on the blade surface at the same time, so that the blade always remains clean, thereby improving the service life of the blade.

[0022] Optionally, the cutting device further includes an auxiliary adjustment mechanism, which is located between the front pressing mechanism and the blade of the cutting machine; the auxiliary adjustment mechanism includes a fixed seat and a suppression roller; the fixed seat is installed on the top of the workbench; the suppression roller is rotatably installed on the fixed seat; the two ends of the suppression roller are respectively provided with a first torsion spring and a second torsion spring, and the torsion directions of the first torsion spring and the second torsion spring are opposite; the rotation direction of the suppression roller is perpendicular to the moving direction of the steel belt, and the suppression roller abuts against the steel belt and drives the steel belt to have a tendency to move in the direction opposite to the moving direction of the blade of the cutting machine.

[0023] By adopting the above technical solution, when the cutting machine cuts the steel belt and the steel belt generates a horizontal displacement, the suppression roller can roll synchronously with the steel belt, and one of the compression springs can be twisted and compressed during the rolling process of the suppression roller, so that it accumulates energy; when the energy accumulates to a certain extent, the torsion of the compression spring is greater than the friction between the suppression roller and the steel belt, and the compression spring resets and drives the suppression roller to rotate in the opposite direction, so that the steel belt returns in the opposite direction, thereby reducing the horizontal displacement amount of the steel belt, and the steel belt is not prone to displacement during the cutting process.

[0024] Optionally, the number of the front pressing mechanisms is multiple, and they are symmetrically arranged on both sides of the steel belt; the front pressing mechanism includes:

[0025] An adaptive pressing plate, which slides on the workbench and abuts against both sides of the steel belt, is used to fixedly press both sides of the steel belt;

[0026] A pressure rod, which slides vertically on the adaptive pressing plate, is used to press the steel belt against the workbench;

[0027] A movable push rod, which is rotatably connected to the adaptive pressing plate;

[0028] An installation cylinder, which is installed on the workbench and is used for the telescopic installation of the movable push rod;

[0029] The driving spring is sleeved on the movable push rod and located inside the mounting cylinder, and is used to press the adaptive pressing plate against both sides of the steel strip.

[0030] The adaptive pressing plate is provided with an auxiliary spring. One end of the auxiliary spring is connected to the adaptive pressing plate, and the other end abuts against the mounting cylinder. The auxiliary spring drives the adaptive pressing plate to rotate.

[0031] A pressing disc for pressing the steel strip against the workbench is provided at the bottom of the pressing rod.

[0032] The adaptive pressing plate has an expanded state and an abutting state. When the adaptive pressing plate is in the expanded state, the auxiliary spring drives the adaptive pressing plate to rotate and forms an included angle with the side wall of the steel strip. An expanding included angle for the horizontal insertion of the steel strip is formed between the two adaptive pressing plates on both sides of the steel strip. When the adaptive pressing plate is in the abutting state, the adaptive pressing plate is parallel to the steel strip and presses against the side wall of the steel strip, and the pressing rod vertically presses against the top of the steel strip.

[0033] By adopting the above technical solution, during the movement of the steel strip towards the cutting device, the steel strip moves along the surface of the adaptive pressing plate and drives the adaptive pressing plate to rotate from the expanded state to the abutting state. At this time, both the driving spring and the auxiliary spring can press the adaptive pressing plate against the side wall of the steel strip.

[0034] Adaptive pressing plates are provided on both sides of the steel strip, and the steel strip can be clamped between the adaptive pressing plates on both sides, making it difficult for the steel strip to move horizontally. And since the distance between the adaptive pressing plates on both sides is not manually controlled but adjusted according to the width of the steel strip itself, the front pressing device can be applied to steel strips of different width sizes, which is quite practical.

[0035] Optionally, the front pressing mechanism further includes:

[0036] A rotating sleeve is rotatably connected to the adaptive pressing plate and threadedly sleeved on the outside of the pressing rod, and is used to drive the pressing rod to vertically lift and lower.

[0037] An adjusting nut is threadedly connected to the pressing rod and located between the rotating sleeve and the bottom end of the pressing rod, and is used to adjust the lifting and lowering distance of the pressing rod.

[0038] A driving assembly is vertically slidably arranged on the adaptive pressing plate and is connected to the rotating sleeve by means of gear meshing, and is used to drive the rotating sleeve to rotate.

[0039] A driving cylinder is arranged on the top of the adaptive pressing plate and is used to drive the driving assembly to lift and lower.

[0040] The driving assembly includes a rotating wheel and a first helical gear connected to the rotating shaft.

[0041] A second helical gear is fixedly connected to the bottom of the rotating sleeve.

[0042] The driving assembly drives the rotating wheel to abut against the top of the steel belt, and the driving assembly drives the first helical gear to mesh with the second helical gear.

[0043] A return spring is sleeved on the outer side of the pressure rod, and the return spring drives the pressure plate to have a tendency to move upward; a limiting block is provided on the side wall of the pressure rod, and the adaptive pressure plate is provided with a limiting groove for the limiting block to slide.

[0044] The push rod of the driving cylinder is connected to the driving assembly; the front pressing mechanism has a release state and a pressing state. When the front pressing mechanism is in the release state, the driving cylinder drives the driving assembly to rise, the rotating wheel is separated from the surface of the steel belt, the first helical gear is separated from the second helical gear, and the return spring drives the pressure plate to rise and separate from the steel belt; when the front pressing mechanism is in the pressing state, the driving cylinder drives the driving assembly to descend, the rotating wheel abuts against the steel belt and rolls synchronously, the first helical gear meshes with the second helical gear and drives the second helical gear to rotate, and the second helical gear drives the pressure plate to descend and abut against the steel belt.

[0045] By adopting the above technical solution, during the process of the steel belt moving towards the cutting device, the driving cylinder drives the rotating wheel to abut against the surface of the steel belt, and the first helical gear meshes with the second helical gear. The rotating wheel can rotate along with the movement of the steel belt, and the first helical gear drives the second helical gear to rotate, so that the pressure plate gradually moves towards the steel belt and presses the steel belt against the surface of the workbench. Since the steel belt is pressed by the pressure plate, the steel belt stops moving, and the left and right sides of the steel belt are limited. At this time, the cutting device can cut the steel belt.

[0046] After the steel belt is cut, the driving cylinder drives the rotating wheel to rise, the rotating wheel is separated from the steel belt, and the first helical gear is separated from the second helical gear. At this time, the pressure plate rises under the action of the return spring, so as to be separated from the steel belt, and the steel belt can continue to move.

[0047] By adjusting the position of the adjusting nut, the descending distance of the pressure plate is adjusted, so that the moving distance of the steel belt can be controlled and changed.

[0048] The front pressing mechanism with the above structure can press the steel belt and can control the cutting spacing of the steel belt, which is relatively practical.

[0049] Optionally, the driving assembly further includes a sliding seat and a rotating shaft rotatably connected to the sliding seat; the push rod of the driving cylinder is connected to the top of the sliding seat; the rotating wheel and the first helical gear are both fixed to the rotating shaft; a limiting nut for limiting the first helical gear to the rotating shaft is threadedly installed at the end of the rotating shaft, and the limiting nut abuts against the first helical gear.

[0050] The rotating wheel includes a hub and an anti-slip tire sleeved on the hub; a locking groove penetrating to the center is formed in the circumferential side wall of the hub, and a locking post is slidably installed in the locking groove; a plugging groove is formed in the inner wall of the anti-slip tire; the rotating shaft drives the locking post to insert into the plugging groove.

[0051] The end of the locking post has a first magnetic sheet, and a second magnetic sheet is arranged in the plugging groove. The first magnetic sheet abuts against the second magnetic sheet and has mutually repulsive magnetism.

[0052] A positioning groove is formed in the side wall of the hub, and the anti-slip tire is provided with a positioning protrusion matching with the positioning groove.

[0053] By adopting the above technical solution, when the anti-slip tire is installed on the hub by the cooperation of the positioning protrusion and the positioning groove, the rotating shaft is inserted into the hub of the rotating wheel, and the rotating shaft can drive the end of the locking post to insert into the plugging groove. At this time, the hub and the anti-slip tire are locked. When the rotating wheel rolls on the steel belt, it is not easy for the hub and the anti-slip tire to slip, so as to accurately control the cutting length of the steel belt.

[0054] When disassembling the anti-slip tire, the hub is removed from the rotating shaft. At this time, under the repulsive force of the first magnetic sheet and the second magnetic sheet, the locking post withdraws from the plugging groove, and the anti-slip tire can be removed from the hub, which is relatively convenient.

[0055] Optionally, the rear pressing mechanism includes mounting blocks symmetrically arranged on both sides of the steel belt, an air cylinder arranged between the two mounting blocks, and an air pump arranged on one side of the workbench; a plurality of pressing rods are arranged at intervals at the bottom of the air cylinder, and the pressing rods vertically lift and slide in the air cylinder; the air pump is connected to one side of the air cylinder and drives the pressing rods to press on the steel belt.

[0056] By adopting the above technical solution, the pressing method of the rear pressing mechanism is specifically disclosed. The air cylinder is inflated by the air pump, so that the pressing rods on the air cylinder can extend out and press on the steel belt. The above pressing method is relatively simple.

[0057] Optionally, the rear pressing mechanism further includes a turning plate which is horizontally rotatably connected to the workbench. One end of the turning plate has a driving portion, and the other end has a guiding portion. An adjustment groove is formed in the side wall of the mounting block along the length direction. The end of the air cylinder slides in the adjustment groove and has a pressing state and a retracting state. A return spring is arranged in the adjustment groove, and the return spring drives the air cylinder to reset to the pressing state.

[0058] When the return spring drives the return spring to be in the pressing state, the pressing rod presses the steel strip against the driving portion, and the turning plate is horizontally arranged. When the air cylinder is in the retracting state, the driving portion drives the air cylinder to horizontally slide, and the guiding portion is in an inclined state.

[0059] By adopting the above technical solution, during the process of the cutting machine cutting the steel strip, the pressing rod presses the steel strip against the driving portion of the turning plate. After the steel strip is cut, since the center of gravity of the steel strip is located at the guiding portion, the steel strip rotates synchronously with the turning plate. At this time, the driving portion drives the air cylinder to move to the retracting state, the turning plate can be in an inclined state, and the steel strip can slide on the turning plate for blanking. With the above structure, the blanking of the steel strip is relatively simple.

[0060] Optionally, the flattening device includes:

[0061] A flattening roller set symmetrically arranged on both sides of the workbench for flattening the steel strip;

[0062] Contact pieces arranged on the flattening roller set and abutting against both sides of the steel strip;

[0063] A clamping assembly arranged on the flattening roller set for pressing the contact pieces against both sides of the steel strip;

[0064] The flattening roller set includes a lower roller rotatably arranged on the workbench and abutting against the lower surface of the steel strip and an upper roller rotatably arranged on the workbench and abutting against the upper surface of the steel strip;

[0065] A sliding rod is circumferentially arranged on the side wall of the contact piece, and a sliding hole for the sliding rod to telescopically slide is formed in the upper roller. A tension spring is arranged in the sliding hole, and the tension spring drives the sliding rod to always have a tendency to retract into the sliding hole;

[0066] The clamping assembly includes a clamping plate sleeved on the upper roller, a threaded rod fixedly connected to the side wall of the clamping plate, and adjusting sleeves respectively threadedly connected to the threaded rods on both sides. The clamping plate abuts against the side of the contact piece away from the steel strip. The upper rollers on one side of the steel strip all penetrate through the same clamping plate.

[0067] By adopting the above technical solution, when steel strips of different width dimensions pass between the flattening roller groups, the abutting pieces can adapt to the width of the steel strip and clamp on both sides of the steel strip. Then, by manually rotating the adjustment sleeve, the clamping plate moves horizontally and presses the abutting pieces against the steel strip. At this time, the steel strip can be limited in the horizontal direction, so that the steel strip is not prone to horizontal movement during the flattening process, and the steel strip can be stably conveyed to the rolling device for rolling operation.

[0068] Optionally, the flattening device further includes a centering auxiliary bar; the centering auxiliary bar is located on the center line between the two flattening roller groups; a locking ring is provided at the circumferential middle position of the adjustment sleeve, and the centering auxiliary bar has a fixing groove for the locking ring to be inserted into, and an anti-rotation member for pressing the locking ring is provided in the fixing groove;

[0069] The workbench is provided with guide rods, and the centering auxiliary bar slides vertically on the guide rods; a compression spring is sleeved on the guide rods, and the compression spring drives the centering auxiliary bar to press against the adjustment sleeve.

[0070] By adopting the above technical solution, after the clamping pieces press the steel strip left and right, by driving the adjustment sleeve to move horizontally, the locking ring is engaged into the fixing groove of the centering auxiliary bar, so that the steel strip can be adjusted to the center of gravity position between the two flattening roller groups, and the steel strip can always be kept at the center position, so that the rolling effect of the steel strip in the subsequent rolling operation is better.

[0071] In summary, the present invention includes at least one of the following beneficial technical effects:

[0072] 1. A steel strip rolling and forming device, by setting the cutting machine to a reciprocating swing cutting method left and right, during the process of the cutting machine cutting the steel strip, the horizontal position of the steel strip can be adjusted so that the steel strip is always in the initial position;

[0073] 2. By setting an auxiliary adjustment mechanism, the auxiliary adjustment mechanism can further control the horizontal displacement of the steel strip, so that the steel strip is not prone to horizontal displacement;

[0074] 3. By setting a front pressing device, the front pressing device can press the steel strip against the workbench, and the front pressing device can adjust the moving cutting distance of the steel strip to control the length of the steel strip after cutting. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0091] The following further elaborates on the present invention in conjunction with the attached Figures 1 - 15 drawings.

[0092] An embodiment of the present invention discloses a steel strip rolling and forming device.

[0093] Refer to Figure 1, A steel strip rolling and forming device includes a workbench 1 and a flattening device 2, a rolling device 3, a cutting device 4, a front pressing mechanism 5, and a rear pressing mechanism 6 installed on the workbench 1. The initial steel strip is in the state of a coiled steel coil and is installed on a specific winding device. The flattening device 2 is used to pull the steel strip out of the winding device and flatten the coiled steel strip. The rolling device 3 is used to roll the flattened steel strip to form a specific shape. The cutting device 4 is used to cut the rolled and formed steel strip to form a steel strip of a specific length and perform blanking processing. Both the front pressing mechanism 5 and the rear pressing mechanism 6 are used to press the steel strip against the surface of the workbench 1 so that the steel strip can be relatively stable when the cutting device 4 cuts the steel strip.

[0094] Referring to Figure 2 , the flattening device 2 includes a flattening roller set 21, a contact piece 22, a clamping assembly 23, and a centering auxiliary strip 24. The workbench 1 is provided with a slideway 11 for the steel strip to pass through horizontally. The flattening roller set 21 is symmetrically arranged on both inner walls of the slideway 11. The flattening roller set 21 includes an upper roller 211 and a lower roller 212, and both the upper roller 211 and the lower roller 212 are rotatably arranged on the inner wall of the slideway 11. Among them, the upper roller 211 abuts against the upper surface of the steel strip, and the lower roller 212 abuts against the lower surface of the steel strip, and the two press the steel strip in the middle. In this embodiment, the number of both the upper roller 211 and the lower roller 212 is multiple and they are arranged in one-to-one correspondence, and both are arranged at intervals along the length direction of the slideway 11.

[0095] Referring to Figure 3 , the contact piece 22 is sleeved on the upper roller 211. A sliding rod 221 is circumferentially arranged on the side wall of the contact piece 22. The upper roller 211 is provided with a sliding hole 2111 for the sliding rod 221 to telescopically slide. A tension spring 2112 is arranged in the sliding hole 2111. One end of the tension spring 2112 is connected to the bottom surface of the sliding hole 2111, and the other end is connected to the sliding rod 221. The tension spring 2112 drives the sliding rod 221 to always have a tendency to retract into the sliding hole 2111. A flexible ring 222 is adhesively bonded to the side wall of the contact piece 22 facing the sliding rod 221, and the flexible ring 222 can abut against the side wall of the steel strip.

[0096] Referring to Figure 2 and Figure 3 , when the steel strip moves in the slideway 11, the contact pieces 22 on both sides of the slideway 11 can telescopically slide on the upper roller 211 and can abut against both sides of the steel strip, so as to clamp the steel strip between the contact pieces 22 on both sides.

[0097] The clamping assembly 23 includes a clamping plate 231, a threaded rod 232, and an adjustment sleeve 233. The clamping plate 231 is a long strip-shaped plate, and the clamping plate 231 is sleeved on the upper roller 211. The clamping plate 231 abuts against the side of the abutting piece 22 away from the sliding rod 221. In this embodiment, the upper rollers 211 on one side of the slideway 11 all pass through the same clamping plate 231. The number of the threaded rods 232 is two, which are horizontally and fixedly connected to the two end portions of the clamping plate 231. The adjustment sleeve 233 is used to connect the threaded rods 232 on both sides of the slideway 11, and the threaded rods 232 on both sides of the slideway 11 are both threadedly connected to the end portion of the adjustment sleeve 233.

[0098] When the adjustment sleeve 233 is rotated, the threaded rod 232 can telescopically slide on the adjustment sleeve 233, so that the clamping plate 231 can slide on the upper roller 211, and the clamping plate 231 further drives the abutting piece 22 to abut tightly against the side wall of the steel strip.

[0099] Since the length of the clamping plate 231 is relatively long, by adjusting the adjustment sleeve 233 at one end of the clamping plate 231, the clamping plate 231 is prone to tilt. In order to prevent the clamping plate 231 from tilting easily, the adjustment sleeves 233 at both ends of the clamping plate 231 are connected by a connecting rod 234, and the adjustment sleeve 233 and the connecting rod 234 are matched by means of gear meshing. When the adjustment sleeve 233 on one side is rotated, the adjustment sleeve 233 on the other side can rotate synchronously, so as to drive the clamping plate 231 to move better.

[0100] The centering auxiliary bar 24 is a square long rod, which is located on the center line between the flattening roller groups 21 on both sides of the slideway 11. Both ends of the centering auxiliary bar 24 are installed on the workbench 1 through support bars 25. The workbench 1 is provided with guide rods 26, and the support bars 25 vertically slide on the guide rods 26. The guide rods 26 are sleeved with compression springs 27, and the compression springs 27 drive the support bars 25 to vertically lift and lower, so that the centering auxiliary bar 24 can move up and down.

[0101] A fixing groove 241 is formed in the bottom of the centering auxiliary bar 24 along the length direction. A locking ring 2331 is provided at the circumferential middle of the adjustment sleeve 233. By manually adjusting the vertical position of the centering auxiliary bar 24 and the horizontal position of the adjustment sleeve 233, the locking ring 2331 can be embedded into the fixing groove 241. At this time, the clamping plate 231 can drive the steel strip to be in the central position of the slideway 11.

[0102] Refer to Figure 2 and Figure 4, an anti-rotation member is provided in the fixing groove 241. The anti-rotation member includes a pressing head 2411, an unlocking rod 2412, and an anti-rotation spring 2413. The pressing head 2411 is embedded in the inner side wall of the fixing groove 241. The unlocking rod 2412 is integrally connected to the pressing head 2411, and the unlocking rod 2412 passes through the centering auxiliary strip 24. The anti-rotation spring 2413 is sleeved on the unlocking rod 2412, and it drives the pressing head 2411 to always have a tendency to move into the fixing groove 241 and press against the locking ring 2331.

[0103] Referring to Figure 1 , the rolling device 3 includes a plurality of rolling wheels 31. The rolling wheels 31 have convex rings adapted to the to-be-formed shape of the steel strip, and the sizes of the convex rings of adjacent rolling devices 3 gradually increase along the moving direction of the steel strip, so as to gradually form the shape of the steel strip. Since the rolling device 3 is a prior art, it will not be elaborated here.

[0104] Referring to Figure 5 and Figure 6 , the cutting device 4 includes a cutting machine 41, a mounting seat 42, a vertical guide rail 43, a driving motor 44, and an auxiliary adjustment mechanism 45. The workbench 1 is provided with a receiving cavity 12. The cutting machine 41, the mounting seat 42, the vertical guide rail 43, and the driving motor 44 are all installed in the receiving cavity 12. A cutting opening 13 is also provided at the top of the workbench 1. The cutting opening 13 penetrates through to the receiving cavity 12 and is used for the blade of the cutting machine 41 to extend out.

[0105] There are two vertical guide rails 43, which are symmetrically arranged on both sides in the receiving cavity 12. The mounting seat 42 is a rectangular block and is vertically slidably mounted on the vertical guide rail 43. The cutting machine 41 is horizontally slidably mounted on the mounting seat 42. With the above structure, the blade of the cutting machine 41 can move and cut in a square vertical plane. Among them, the vertical plane has the length of the vertical guide rail 43 as the height and the length of the mounting seat 42 as the width.

[0106] A driving plate 46 is fixedly connected to the output shaft of the driving motor 44, and a traction block 461 is mounted on the driving plate 46. The traction block 461 is a square block. In this embodiment, the driving motor 44 is a steering gear and can swing within a set rotation angle. The rotation angle is 120° - 180°, and 120° is preferably here. The driving motor 44 can drive the driving plate 46 to swing reciprocally. At this time, the moving path of the traction block 461 is an arc. The workbench 1 is provided with an abutting platform 14 on the inner bottom surface of the receiving cavity 12. When the driving plate 46 rotates to the left and right ends of the workbench 1, it respectively abuts against the top of the abutting platform 14, so that the driving plate 46 is not prone to excessive rotation.

[0107] The traction block 461 is coaxially and rotationally connected to the blade of the cutting machine 41. When the driving motor 44 drives the driving plate 46 to rotate reciprocally, the cutting machine 41 can rotate synchronously with the driving plate 46, so that the cutting machine 41 can reciprocally cut the steel strip on the top of the workbench 1. When the cutting machine 41 starts cutting from one side of the steel strip, the cutting machine 41 can cut the next steel strip from the other side of the steel strip.

[0108] In order to enable the cutting machine 41 to be applicable to steel strips of different width dimensions, the traction block 461 can be adjusted by moving on the driving plate 46, so as to increase or decrease the moving radius of the traction block 461. The driving plate 46 is provided with a chute 462 radially along the output shaft of the driving motor 44. The shape of the slide is adapted to the traction block 461, and the traction block 461 is slidably installed in the chute 462. A driving screw 463 is threadedly installed on the side wall of the driving plate 46. The driving screw 463 penetrates into the chute 462, and the driving screw 463 is threadedly connected to the traction block 461. By rotating the driving screw 463, the traction block 461 can move in the chute 462.

[0109] Referring to Figure 5 and Figure 7 and, the mounting seat 42 has a water passing cavity 421 for the cleaning water to flow through inside. Both ends of the mounting seat 42 also have an inlet and an outlet for the cleaning water to flow in and out. Spray heads 422 are arranged at intervals along the length direction at the bottom of the mounting seat 42. The spray heads 422 are communicated with the water passing cavity 421, and the spray heads 422 are directly opposite to the blade of the cutting machine 41. A pressure sensor 47 is arranged on the vertical guide rail 43. When the cutting machine 41 finishes the cutting operation, the mounting seat 42 slides on the vertical guide rail 43 and abuts against the pressure sensor 47. At this time, the cutting machine 41 is located in the accommodating cavity 12, and the pressure sensor 47 controls the spray heads 422 to spray water on the blade of the cutting machine 41, so as to cool the blade of the cutting machine 41 and clean the metal chips on its surface.

[0110] A return port 15 penetrating through to the accommodating cavity 12 is formed in the side wall of the workbench 1. The cleaning water for cleaning the blade of the cutting machine 41 sprayed from the spray heads 422 can flow out of the accommodating cavity 12 through the return port 15, so that the accommodating cavity 12 is not prone to liquid accumulation.

[0111] Referring to Figure 5 and Figure 8 and, in this embodiment, the number of the auxiliary adjustment mechanisms 45 is two, which are symmetrically arranged on both sides of the steel strip and located on the top of the workbench 1. The auxiliary adjustment mechanism 45 includes a fixed seat 451 and a restraining roller 452. Among them, the fixed seat 451 is used for installing the restraining roller 452, and the restraining roller 452 is rotatably installed on the fixed seat 451. First torsion springs 453 and second torsion springs 454 are respectively arranged at both ends of the rotating shaft of the restraining roller 452, and the torsion directions of the first torsion spring 453 and the second torsion spring 454 are opposite.

[0112] The suppression roller 452 abuts against the top of the steel strip, and the rotation direction of the suppression roller 452 is perpendicular to the moving direction of the steel strip. When the cutting machine 41 cuts the steel strip and causes the steel strip to have a lateral displacement, the suppression roller 452 drives the steel strip to have a tendency to move in the direction opposite to the moving direction of the blade of the cutting machine 41. The suppression roller 452 rotates synchronously with the steel strip first. When the torsion force of the first torsion spring 453 or the second torsion spring 454 is greater than the frictional force received by the suppression roller 452, the first torsion spring 453 or the second torsion spring 454 can drive the steel strip to reset, thereby further reducing the distance of the horizontal displacement of the steel strip.

[0113] Refer to Figure 1 , the front pressing mechanism 5 and the rear pressing mechanism 6 are respectively located on both sides of the cutting machine 41. The front pressing mechanism 5 is installed on the workbench 1 and is located between the rolling device 3 and the cutting device 4. The rear pressing mechanism 6 is installed on the workbench 1 and is located on the side of the cutting device 4 away from the rolling device 3. When the cutting device 4 cuts the steel strip, the front pressing mechanism 5 and the rear pressing mechanism 6 can press the steel strip on both sides of the cutting device 4.

[0114] Refer to Figure 1 and Figure 9 , the number of the front pressing mechanisms 5 is two, and they are symmetrically arranged on both sides of the steel strip. The front pressing mechanism 5 includes a mounting cylinder 51, a movable push rod 52, a driving spring 53, an adaptive pressing plate 54, a pressing rod 55, a rotating sleeve 56, an adjusting nut 57, a driving assembly 58 and a driving cylinder 59.

[0115] The mounting cylinder 51 is a hollow square cylinder with one end open, and is fixedly installed on the workbench 1. The movable push rod 52 telescopically slides in the mounting cylinder 51 and extends out from the opening of the mounting cylinder 51. The driving spring 53 is sleeved outside the movable push rod 52, one end of which is connected to the inner bottom surface of the mounting cylinder 51, and the other end is connected to the movable push rod 52. The driving spring 53 drives the movable push rod 52 to always have a tendency to extend out of the mounting cylinder 51.

[0116] The cross section of the adaptive pressing plate 54 is L-shaped, and includes a side plate 541 and a top plate 542 connected to the top of the side plate 541. The side plate 541 is rotatably connected to the end of the movable push rod 52. When the driving spring 53 drives the movable push rod 52 to move, the adaptive pressing plate 54 can move synchronously with the movable push rod 52 and be pressed against the side wall of the steel strip. One end of the side plate 541 is provided with an auxiliary spring 543. One end of the auxiliary spring 543 is connected to the side plate 541, and the other end is connected to the side wall of the mounting cylinder 51. The auxiliary spring 543 can drive the side plate 541 to rotate.

[0117] The adaptive pressing plate 54 has an expanded state and an abutting state. When the adaptive pressing plate 54 is in the expanded state, the auxiliary spring 543 drives the adaptive pressing plate 54 to rotate and form an angle with the side wall of the steel strip. At this time, a flaring angle for the horizontal insertion of the steel strip is formed between the two side plates 541 on both sides of the steel strip. When the steel strip horizontally moves into the flaring angle, the steel strip slides along the surface of the side plate 541, causing the side plate 541 to rotate and move against the springs of the auxiliary spring 543 and the driving spring 53. Finally, the side plate 541 abuts against the side wall of the steel strip in parallel, and the driving spring 53 and the auxiliary spring 543 press the side plate 541 against the side wall of the steel strip. At this time, the adaptive pressing plate 54 is in the abutting state, and the distance between the two adaptive pressing plates 54 is the width of the steel strip.

[0118] Referring to Figure 10 , the driving assembly 58 includes a sliding seat 581, a rotating shaft 582, a rotating wheel 583, a first helical gear 584, and a limit nut 585. The sliding seat 581 is a square block. The rotating shaft 582 is horizontally rotatably installed on the sliding seat 581. The rotating shaft 582 includes a first shaft section 5821 and a second shaft section 5822 connected to the first shaft section 5821. The diameter of the first shaft section 5821 is larger than that of the second shaft section 5822. The second shaft section 5822 is provided with a keyway 5823 along its length direction, and the end of the second shaft section 5822 far from the first shaft section 5821 has a thread. The rotating wheel 583 and the first helical gear 584 are both limitedly installed on the second shaft section 5822, and both the rotating wheel 583 and the first helical gear 584 have through holes adapted to the keyway 5823. The first helical gear 584 presses the rotating wheel 583 against the end face of the first shaft section 5821. The limit nut 585 is threadedly connected to the second shaft section 5822 and abuts against the first helical gear 584. The limit nut 585 limits and presses the first helical gear 584 against the rotating wheel 583.

[0119] Referring to Figure 10 and Figure 11 , the rotating wheel 583 includes a hub 5831 and an anti-slip tire 5832 sleeved on the hub 5831. A locking groove 5833 penetrating through to the central through hole is formed on the circumferential side wall of the hub 5831, and a locking post 5834 is slidably installed in the locking groove 5833. A plugging groove 5835 is formed on the inner wall of the anti-slip tire 5832. When the rotating wheel 583 is installed on the rotating shaft 582, the rotating shaft 582 drives the locking post 5834 to insert into the plugging groove 5835, so that it is not easy for the anti-slip tire 5832 to slip relative to the hub 5831. In this embodiment, the number of locking posts 5834 is four, and they are evenly arranged circumferentially on the hub 5831.

[0120] The end of the locking post 5834 is provided with a first magnetic sheet 5836, and a second magnetic sheet 5837 is arranged in the insertion slot 5835. The first magnetic sheet 5836 abuts against the second magnetic sheet 5837 and the magnetic forces are repulsive. When the rotating wheel 583 is removed from the rotating shaft 582, the locking post 5834 moves into the central through hole under the repulsive force of the first magnetic sheet 5836 and the second magnetic sheet 5837, and the end of the locking post 5834 withdraws from the insertion slot 5835. At this time, the anti-slip tire 5832 can be removed from the wheel hub 5831.

[0121] Referring to Figure 10 and Figure 12 In order to enable the locking post 5834 to better align and cooperate with the insertion slot 5835, a positioning slot 5838 is provided on the side wall of the wheel hub 5831, and the anti-slip tire 5832 is provided with a positioning protrusion 5839 that cooperates with the positioning slot 5838. In this embodiment, the number of the positioning protrusions 5839 is four, which corresponds to the number of the locking posts 5834 one by one.

[0122] Referring to Figure 9 and Figure 10 On the side plate 541, a slide rail 544 is vertically arranged, and the sliding seat 581 is slidably mounted on the slide rail 544. The driving cylinder 59 is arranged on the top of the top plate 542. The push rod of the driving cylinder 59 passes through the top plate 542 and is connected to the top of the sliding seat 581. The driving cylinder 59 drives the driving assembly 58 to vertically slide up and down on the slide rail 544.

[0123] Referring to Figure 10 and Figure 13 The rotating sleeve 56 is a hollow cylinder, and it is rotatably mounted on the bottom surface of the top plate 542. A second bevel gear 561 is integrally welded to the bottom end of the rotating sleeve 56, and the second bevel gear 561 can be meshed with the first bevel gear 584. The pressure rod 55 is vertically slidably mounted on the top plate 542, and the pressure rod 55 passes through the rotating sleeve 56. The pressure rod 55 is in threaded cooperation with the rotating sleeve 56. A pressure plate 551 is arranged at the bottom of the pressure rod 55. The pressure plate 551 is a circular thin plate. The pressure plate can vertically move up and down with the pressure rod 55 and press tightly on the surface of the steel strip. A limiting block 552 is provided on the side wall of the top end of the pressure rod 55. The top plate 542 is provided with a limiting groove 5421 for the limiting block 552 to slide. When the pressure rod 55 vertically moves up and down on the top plate 542, the limiting block 552 can vertically slide in the limiting groove 5421.

[0124] By driving the rotating sleeve 56 to rotate, the rotating sleeve 56 can drive the pressure rod 55 to vertically slide downward, so that the pressure plate 551 presses the steel strip tightly.

[0125] The top of the pressure rod 55 has an abutting disc 553, and a return spring 554 is sleeved outside the pressure rod 55. One end of the return spring 554 abuts against the top surface of the top plate 542, and the other end abuts against the abutting disc 553. The return spring 554 always urges the pressure rod 55 to move upward.

[0126] Combined Figure 9 、 Figure 10 and Figure 13 When the front pressing mechanism 5 is in the released state, the driving cylinder 59 urges the driving assembly 58 to rise, the rotating wheel 583 is separated from the surface of the steel strip, the first helical gear 584 is separated from the second helical gear 561, and the return spring 554 urges the pressing plate 551 to rise and separate from the steel strip; when the front pressing mechanism 5 is in the pressing state, the driving cylinder 59 urges the driving assembly 58 to descend, the rotating wheel 583 abuts against the surface of the steel strip and rolls synchronously, the first helical gear 584 meshes with the second helical gear 561 and drives the second helical gear 561 to rotate, and the second helical gear 561 drives the pressing plate 551 to descend and abut against the steel strip, so as to press the steel strip against the workbench 1, realizing the pressing function of the front pressing mechanism 5.

[0127] Referring to Figure 13 The adjusting nut 57 is threadedly connected to the pressure rod 55 and is located between the rotating sleeve 56 and the pressing plate 551. The distance between the top of the adjusting nut 57 and the bottom of the rotating sleeve 56 is the distance that the pressing plate 551 can descend. By changing the position of the adjusting nut 57, the distance that the pressing plate 551 descends can be controlled, so that the length of each section of the steel strip cut can be controlled.

[0128] Referring to Figure 1 and Figure 14 The rear pressing mechanism 6 includes a mounting block 61, an air cylinder 62 and a turning plate 63. The mounting block 61 is a long block with a square cross-section, and the number of the mounting blocks 61 is two, which are symmetrically arranged on both sides of the steel strip. The mounting block 61 is provided with an adjustment groove 611 along the length direction, and both ends of the air cylinder 62 are slidably mounted in the adjustment grooves 611 on both sides. A pressing rod 64 is arranged at the bottom of the air cylinder 62 along the length direction, and the pressing rod 64 vertically moves up and down in the air cylinder 62. The end of the air cylinder 62 is connected to an air pump, and the air cylinder 62 is supplied with air through the air pump, so as to urge the pressing rod 64 to extend out of the air cylinder 62 and press against the steel strip.

[0129] The adjustment groove 611 is provided with a return spring 66. One end of the return spring 66 abuts against the adjustment groove 611, and the other end abuts against the side wall of the air cylinder 62. The return spring 66 always urges the air cylinder 62 to be located at one end of the adjustment groove 611.

[0130] Referring to Figure 14 and Figure 15, the turning plate 63 is rotatably arranged on the top of the workbench 1. The steel belt can pass over the top of the turning plate 63, and the turning plate 63 abuts against the bottom of the steel belt. The turning plate 63 includes a pressing rod 631 located on one side of the rotation axis and a guiding portion 632 located at the other end of the rotation axis. The length of the guiding portion 632 is much greater than the length of the pressing rod 631.

[0131] Referring to Figure 14 and Figure 15 , the air cylinder 62 has a pressing state and a yielding state. When the air cylinder 62 is in the pressing state, the return spring 66 is in a natural elongation state. The air cylinder 62 is located on one side of the adjustment groove 611. At this time, the pressing rod 64 of the air cylinder 62 presses the steel belt against the top of the pressing rod 631, and both the turning plate 63 and the steel belt are in a horizontal state. When the steel belt is cut, due to the gravity of the guiding portion 632 and the steel belt being much greater than the gravity of the pressing rod 631, the center of gravity of the turning plate 63 is located on the guiding plate. At this time, the turning plate 63 drives the air cylinder 62 to move against the return spring 66, and the air cylinder 62 slides to the other side of the adjustment groove 611. Both the turning plate 63 and the steel belt are in an inclined state, and the steel belt can slide and discharge along the guiding plate. At this time, the air cylinder 62 is in the yielding state.

[0132] Referring to Figure 14 and Figure 15 , after the steel belt is discharged, the return spring 66 drives the air cylinder 62 to slide back to the pressing state again, and the air pump 63 drives the pressing rod 64 to press against the steel belt.

[0133] The implementation principle of the steel belt rolling and forming equipment in the embodiment of the present invention is as follows: The cutter 41 is controlled by the steering gear to perform a reciprocating cutting motion left and right, and the auxiliary adjustment mechanism 45 is used for auxiliary adjustment. When the steel belt has a horizontal displacement during the cutting process of the cutter 41, both the cutter 41 and the auxiliary adjustment mechanism 45 can synchronously adjust the steel belt to make the steel belt return to the initial position.

[0134] The above are all the preferred embodiments of the present invention. The protection scope of the present invention is not limited hereby.
