Description

Technical Field

[0001] This invention relates to the field of cold bending forming equipment technology, and more specifically, to a cold bending equipment for metal sheet for simulating bamboo processing. Background Technology

[0002] In sheet metal processing, cold bending forming equipment is a commonly used tool. It can process sheet metal into components of various shapes. The equipment works in concert to cold bend sheet metal according to design requirements. The advantage of cold bending forming equipment is that it can process at room temperature, avoiding the impact of high-temperature processing on metal materials and better maintaining the material's performance and strength. Cold bending forming equipment can also process large and complex components, with high production efficiency and processing accuracy. It can improve production efficiency and processing quality, and is one of the indispensable pieces of equipment in sheet metal processing.

[0003] In the cold bending forming process of simulated bamboo metal sheets, the sheet material needs to be stably fed into the cold bending rollers by a conveying mechanism, and then continuously rolled and formed by the cold bending rollers. However, existing cold bending equipment usually relies on ordinary conveying rollers or fixed limiting components to guide the sheet material during the conveying stage. When there is a deviation in the feeding position of the sheet material, it is easy for the sheet material to gradually shift to the left or right during the conveying process, causing the sheet material to fail to enter the cold bending roller group stably along the center line of the equipment, thus affecting the dimensional accuracy and forming consistency of the subsequent cold bending forming. Moreover, the lateral limiting structure in existing equipment mostly uses fixed baffles or ordinary guide wheels to limit the edge of the sheet material. When the material deviates from its designated path, the limiting components can only passively block the sides of the sheet, making it difficult to actively adjust the conveying force on both sides of the sheet. If the sheet continues to deviate, the edges of the sheet are prone to hard friction or compression with the limiting components, causing problems such as scratches, curling, and burr jamming on the sheet edges. This is especially true for thin metal sheets used in the processing of simulated bamboo, which are thin and have low edge stiffness. If they continue to enter the cold bending rollers while deviating, the sheet may be fed at an angle, resulting in a decrease in the surface quality of the finished product. How to invent a cold bending device for thin metal sheets used in the processing of simulated bamboo to solve these problems has become an urgent problem for those skilled in the art. Summary of the Invention

[0004] To overcome the above shortcomings, the present invention provides a metal sheet cold bending device for simulating bamboo processing, which aims to solve the problem that for metal sheets used for simulating bamboo processing, which are thin and have low edge stiffness, continuing to enter the cold bending roller in a deviated state may easily lead to oblique feeding of the sheet and a decrease in the surface quality of the finished product.

[0010] Preferably, the protective component includes a protective frame, which is detachably connected to the upright plate. A sliding rod is fixedly connected to the inner wall of the protective frame, and a bidirectional lead screw is rotatably connected to the inner wall of the protective frame. The bidirectional lead screw is located below the sliding rod, and a rotating wheel is fixedly connected to one end of the bidirectional lead screw located on the outer side of the protective frame.

[0011] Preferably, the protective assembly further includes a floating mechanism, which includes a movable block that is threadedly connected to a bidirectional lead screw. The movable block is slidably connected to a slide rod and a protective frame, respectively. A fixed cylinder is fixedly connected to the end of the movable block away from the protective frame, and an extension plate is fixedly connected to the side wall of the fixed cylinder.

[0012] Preferably, the fixed cylinder is provided with a movable column and a telescopic spring inside. The movable column is T-shaped and is slidably connected to the inner wall of the fixed cylinder. The two ends of the telescopic spring are respectively fixedly connected to the moving block and the side wall of the movable column. A fixed frame is fixedly connected to the end of the movable column away from the telescopic spring. A floating pressure roller is rotatably connected to the side wall of the fixed frame. The floating pressure roller is located directly above the conveying roller.

[0013] Preferably, the side wall of the movable column is provided with a sliding groove, the sliding groove is arranged in a parallelogram, and a matching slider is slidably connected to the inner wall of the sliding groove. An infrared displacement sensor is provided on the side wall of the movable column, the infrared displacement sensor is located on one side of the slider, one end of the slider is fixedly connected to a sliding plate one, and the other end of the slider is fixedly connected to a sliding plate two. The sliding plate one and the sliding plate two are slidably connected to the two side walls of the fixed cylinder, and the sliding plate two is provided with an insertion hole on the side wall of the fixed cylinder.

[0015] The beneficial effects of this invention are: 1. This invention enhances the frictional traction between the two sides of the sheet metal and the conveying roller by setting symmetrically distributed threaded strips at both ends of the conveying roller, thereby reducing the risk of slippage and deviation during the conveying process of the sheet metal, and improving the continuity, stability and forming accuracy of the cold bending forming of simulated bamboo metal sheet metal; and by setting slide rods, bidirectional lead screws, rotating wheels and moving blocks in the protective frame, the floating mechanisms on both sides can move synchronously towards or away from each other, thereby adapting to sheets of different widths and keeping the sheet metal conveyed in the center.

[0016] 2. This invention, by setting up a fixed cylinder, a movable column, a telescopic spring, a fixed frame, and a floating pressure roller, enables the floating pressure roller to elastically press the sheet material. When the sheet material deviates, it works in conjunction with the guide wheel, rotating rod, lever, slide plate, slider, and slide groove to reduce the pressing force on the deviating side of the floating pressure roller while maintaining traction on the other side. This achieves flexible correction through the difference in traction between the left and right sides. At the same time, the brush on the outer wall of the guide wheel can clean the burrs on the edge of the sheet material, and the infrared displacement sensor can control the motor to stop when the slider displacement exceeds the limit. This achieves a synergistic effect of guidance, anti-deviation, edge protection, and abnormal shutdown protection. Attached Figure Description

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0021] Reference Figures 1-9 A metal sheet cold bending device for simulating bamboo processing includes a base 1 and a support base 2. A protective component 6 and a conveying component 7 are provided on one side of the base 1. The protective component 6 is fixedly connected to the conveying component 7. The conveying component 7 is used to assist in conveying the sheet to the cold bending roller 8, and the protective component 6 is used to protect the sheet during the conveying process.

[0022] Furthermore, the upper end of the base 1 is fixedly connected to the support 2. The support 2 is provided with a fixed bearing seat 3 and an adjusting bearing seat 5 inside. The adjusting bearing seat 5 is slidably connected to the support 2. Both the fixed bearing seat 3 and the adjusting bearing seat 5 are rotatably connected to a cold bending roller 8. The support 2 is threadedly connected to an adjusting rod 4. One end of the adjusting rod 4 is rotatably connected to the adjusting bearing seat 5. The side wall of the base 1 is fixedly connected to a drive module 9. The drive module 9 is connected to the cold bending roller 8 below the support 2.

[0023] It should be noted that: The base 1 provides stable support for the entire machine. The support seat 2 is fixedly installed on the upper end of the base 1, forming the mounting support frame for the cold bending roll 8. The support seat 2 has a fixed bearing seat 3 and an adjusting bearing seat 5 inside. The fixed bearing seat 3 remains in a fixed position, providing a stable support reference for the lower cold bending roll 8. The adjusting bearing seat 5 is slidably fitted with the support seat 2 and can move vertically up and down along the inner wall of the support seat 2. It is used to install and support the upper cold bending roll 8. An adjusting rod 4 is threadedly connected to the support seat 2. The lower end of the adjusting rod 4 is rotatably connected to the adjusting bearing seat 5. By rotating the adjusting rod 4, the adjusting bearing seat 5 can be driven to rise and fall, thereby precisely adjusting the roll gap between the upper and lower sets of cold bending rolls 8 to adapt to different thicknesses of metal. To meet the requirements of cold pressing forming of thin sheets and ensure the parallelism of the upper and lower rollers to avoid sheet deviation, excessive springback, and uneven forming, a drive module 9 is fixedly installed on the side wall of the base 1. The drive module 9 forms a transmission connection with the cold bending roller 8 below the support base 2. During operation, the drive module 9 (which is existing technology and will not be described in detail) outputs power to drive the lower cold bending roller 8 to rotate actively. The continuous conveying and roll forming of the thin sheet is achieved by relying on the friction between the roller surface and the sheet. The upper cold bending roller 8 rotates passively with the sheet feed. Under stable pressing constraints, the progressive cold bending forming of the metal sheet is completed, ensuring that the simulated bamboo forming has consistent dimensions and a good surface. All electrical components in the equipment are powered by an external power source and controlled by a controller.

[0024] Reference Figures 3-5 Furthermore, the conveying assembly 7 includes a support frame 72, which is fixedly connected to the upper end of the base 1. A vertical plate 71 is provided at the upper end of the support frame 72, and a motor 74 is fixedly connected to the side wall of the support frame 72. A conveying roller 73 is rotatably connected inside the support frame 72. One end of the conveying roller 73 passes through the side wall of the support frame 72 and is fixedly connected to the motor 74. Symmetrically distributed threaded strips 731 are fixedly connected to both ends of the conveying roller 73. The protective assembly 6 includes a protective frame 61, which is detachably connected to the vertical plate 71. A sliding rod 65 is fixedly connected to the inner wall of the protective frame 61. The inner wall of the protective frame 61 is rotatably connected to a two-way lead screw 66, which is located below the slide bar 65. A rotating wheel 64 is fixedly connected to one end of the two-way lead screw 66 located outside the protective frame 61. The protective assembly 6 also includes a floating mechanism 63, which includes a moving block 631. The moving block 631 is threadedly connected to the two-way lead screw 66. The moving block 631 is slidably connected to the slide bar 65 and the protective frame 61 respectively. A fixed cylinder 632 is fixedly connected to one end of the moving block 631 away from the protective frame 61. An extension plate 635 is fixedly connected to the side wall of the fixed cylinder 632.

[0025] It should be noted that: The conveying assembly 7 consists of a support frame 72, a vertical plate 71, a motor 74, and a conveying roller 73. The support frame 72 is fixedly installed on the upper end of the base 1, providing a stable installation foundation for the conveying mechanism. The vertical plate 71 is located on the upper part of the support frame 72 and is used to achieve a detachable connection with the protective frame 61, which facilitates assembly, debugging, and maintenance. The motor 74 is fixed to the side wall of the support frame 72 to provide power for the conveying of the sheet metal. The conveying roller 73 is rotatably installed inside the support frame 72, with one end penetrating the support frame 72 and fixedly connected to the output end of the motor 74. It is directly driven to rotate by the motor 74 to achieve stable forward conveying of the thin metal sheet. The conveying roller 73 has symmetrically distributed threaded strips 731 at both ends, which can increase the friction between the roller surface and the edge of the sheet metal, improve the conveying stability, assist in centering the sheet metal, and reduce the risk of deviation.

[0026] The protective component 6 uses the protective frame 61 as its main skeleton. The protective frame 61 is detachably connected to the upright plate 71, facilitating overall assembly, disassembly, and position adjustment. A sliding rod 65 is fixed inside the protective frame 61, and a bidirectional lead screw 66 is rotatably mounted thereon. A wheel 64 is provided at the outer end of the bidirectional lead screw 66. Rotating the wheel 64 can drive the bidirectional lead screw 66 to rotate synchronously. The moving block 631 of the floating mechanism 63 forms a threaded engagement with the bidirectional lead screw 66, and simultaneously slides with the sliding rod 65 and the inner wall of the protective frame 61. When the bidirectional lead screw 66 rotates, the moving blocks 631 on both sides move synchronously towards or away from each other along the sliding rod 65, achieving precise adjustment in the width direction to adapt to metal sheets of different widths. A fixed cylinder 632 is fixed at the end of the moving block 631 for installing the floating pressing structure. An extension plate 635 fixed to the side wall of the fixed cylinder 632 is used to install the limiting mechanism 62, so that the floating pressing and the side guide form a linkage to jointly achieve pressing, guiding, and anti-deviation protection during the sheet material conveying process. Example

[0027] Reference Figures 3-9 Furthermore, the protective component 6 also includes a limiting mechanism 62, which includes a rotating rod 623. The rotating rod 623 is rotatably connected to the extension plate 635. One end of the rotating rod 623 is fixedly connected to a lever 624, which is slidably connected to the insertion hole 6371. The other end of the rotating rod 623 is fixedly connected to a vertical rod 622. The outer wall of the vertical rod 622 is rotatably connected to a guide wheel 621, and the outer wall of the guide wheel 621 is provided with a brush 6211.

[0028] It should be noted that: The limiting mechanism 62 uses a rotating rod 623 as its main rotating body. The rotating rod 623 is rotatably mounted on the extension plate 635 and can rotate and swing around its own axis at a certain angle. One end of the rotating rod 623 is fixedly connected to a lever 624, which extends into the insertion hole 6371 of the slide plate 637 and forms a sliding fit. It can be driven to swing with the displacement of the slide plate 637. The other end of the rotating rod 623 is fixedly connected to a vertical rod 622. A guide wheel 621 is rotatably mounted on the outer wall of the vertical rod 622. A brush 6211 is provided on the outer side of the guide wheel 621. The guide wheel 621 always maintains flexible guidance and limiting of the side of the plate. The guide wheel 621 passively rotates with the plate feed, which can reduce the side friction resistance. The brush 6211 can clean the dust and burrs on the edge of the plate in real time, avoiding burrs from scratching the plate or causing guide jamming, realizing the integrated control of automatic centering, anti-deviation and edge protection of the thin metal plate.

[0029] Furthermore, the fixed cylinder 632 is internally provided with a movable column 639 and a telescopic spring 6310. The movable column 639 is T-shaped and slidably connected to the inner wall of the fixed cylinder 632. The two ends of the telescopic spring 6310 are respectively fixedly connected to the moving block 631 and the side wall of the movable column 639. A fixed frame 633 is fixedly connected to the end of the movable column 639 away from the telescopic spring 6310. A floating pressure roller 634 is rotatably connected to the side wall of the fixed frame 633. The floating pressure roller 634 is located directly above the conveying roller 73. A sliding section is opened on the side wall of the movable column 639. The groove 6391 is arranged in a parallelogram shape. The inner wall of the groove 6391 is slidably connected to a matching slider 638. The side wall of the movable column 639 is provided with an infrared displacement sensor 6311. The infrared displacement sensor 6311 is located on one side of the slider 638. One end of the slider 638 is fixedly connected to a sliding plate 636, and the other end of the slider 638 is fixedly connected to a sliding plate 637. The sliding plate 636 and the sliding plate 637 are slidably connected to the two side walls of the fixed cylinder 632 respectively. The sliding plate 637 is provided with an insertion hole 6371 on the side wall of the fixed cylinder 632.

[0030] It should be noted that: Under normal operating conditions, the sheet metal is located in the middle of the conveying roller 73 and is continuously conveyed along the direction close to the cold bending roller 8 under the rotation of the conveying roller 73. At this time, the floating mechanisms 63 on the left and right sides are in the initial clamping state. The movable column 639 drives the fixed frame 633 and the floating pressure roller 634 to maintain appropriate clamping towards the conveying roller 73 under the elastic action of the telescopic spring 6310, so that the floating pressure roller 634 can cooperate with the conveying roller 73 to flexibly clamp the two sides of the sheet metal. At the same time, the guide wheels 621 on the left and right sides are located near the two sides of the sheet metal. The guide wheels 621 can be passively rotated with the conveying of the sheet metal, which can not only limit and guide the edge of the sheet metal, but also reduce the frictional resistance between the side of the sheet metal and the limiting mechanism 62. The brush 6211 set on the outer wall of the guide wheel 621 can clean the dust, burrs or debris on the edge of the sheet metal during the conveying process, so as to prevent burrs from jamming the guide wheel 621 or affecting the stable conveying of the sheet metal.

[0031] When the sheet material begins to shift to the left during conveying, the left edge of the sheet material gradually approaches and presses against the left guide wheel 621. After being pushed laterally by the sheet material, the guide wheel 621, via the upright 622, drives the rotating rod 623 to rotate relative to the extension plate 635. Since a lever 624 is fixedly connected to one end of the rotating rod 623, the rotation of the rotating rod 623 synchronously drives the lever 624 to swing. The lever 624 inserts into the insertion hole 6371 on the slide plate 637 and forms a sliding fit with the insertion hole 6371. Therefore, during the swinging process, the lever 624 can, on the one hand, move within the insertion hole 6371... The sliding mechanism allows for relative sliding within 71, preventing rigid jamming. On the other hand, it can apply a traction force to the slide plate 637 towards the side away from the fixed cylinder 632. After being pulled, the slide plate 637 drives the slider 638 to move. Since the slider 638 is in a limited sliding fit with the groove 6391 on the side wall of the movable column 639, and the groove 6391 is arranged in a parallelogram shape, the lateral movement of the slider 638 will be transformed into the axial movement of the movable column 639 along the inside of the fixed cylinder 632 under the guidance of the groove 6391. This causes the movable column 639 to move towards the side closer to the moving block 631 and compress the telescopic spring 6310.

[0032] When the movable column 639 moves, the fixed frame 633 connected to the end away from the telescopic spring 6310 simultaneously retracts, thereby causing the left floating pressure roller 634 to slightly lift or move away from the conveyor roller 73. As a result, the clamping force of the left floating pressure roller 634 on the left side of the plate decreases, while the right floating pressure roller 634 maintains its original clamping state. Since the clamping contact between the right side of the plate and the conveyor roller 73 is more sufficient, the frictional traction effect obtained by the right side is relatively greater than that of the left side. When the plate continues to be conveyed forward, it will be subject to the correction effect formed by the difference in clamping force between the left and right sides, so that the plate gradually returns from the left-biased state to the center line of the equipment. This process is not completed by rigidly pushing the side of the plate to correct the deviation, but by the continuous linkage of the guide wheel 621 sensing the deviation, the lever 624 transmitting the displacement, the slider 638 and the slide 6391 changing the direction of movement, and the movable column 639 driving the floating pressure roller 634 to change the clamping force, so as to achieve flexible correction of the plate's movement trajectory.

[0033] When the sheet material begins to shift to the right during conveying, its movement is the opposite of when it shifts to the left. The right edge of the sheet material will press against the right guide wheel 621. The right guide wheel 621 drives the right rotating rod 623 to rotate on the corresponding extension plate 635 via the corresponding upright rod 622. This causes the right lever 624 to slide in the insertion hole 6371 of the right slide plate 637 and apply traction to the right slide plate 637. The right slide plate 637 then drives the corresponding slider 638 along the parallelogram groove 63 on the right movable column 639. 91 Sliding causes the right movable column 639 to move toward the corresponding moving block 631 and compress the corresponding telescopic spring 6310, thereby causing the right fixed frame 633 and the right floating pressure roller 634 to make a slight upward or backward movement; at this time, the pressing force of the right floating pressure roller 634 on the right side of the plate decreases, while the left floating pressure roller 634 maintains the original pressure, and the frictional traction between the left side of the plate and the conveying roller 73 is relatively enhanced, so that the plate gradually returns to the left during the continued conveying process, thereby correcting the rightward deviation of the plate's movement trajectory.

[0034] As the sheet material gradually returns to the center of the conveyor roller 73, the pressure exerted by the side of the sheet material on the guide wheel 621 decreases or disappears. The rotating rod 623 is no longer subjected to continuous lateral driving force. At this time, the telescopic spring 6310 releases its elastic potential energy, pushing the movable column 639 to reset in the opposite direction along the fixed cylinder 632. When the movable column 639 resets, it drives the slider 638 to slide in the opposite direction along the slide groove 6391, and through the slide plate 637 and the insertion hole 6371, it drives the lever 624, the rotating rod 623, the upright rod 622, and the guide wheel 621 to gradually return to their initial positions. As the movable column 639 resets, the fixed frame 633 and the floating pressure roller 634 also return to their initial pressing positions, so that the floating pressure rollers 634 on both sides can once again form a basically consistent pressing force on the sheet material, and the sheet material continues to maintain a centered conveying state.

[0035] With the above configuration, the guide wheel 621 is not only used to block the side of the sheet metal, but also serves as a sensing element for sheet metal offset; the rotating rod 623 and the lever 624 serve as transmission elements for offset signals; the sliding plate 637, the slider 638, and the parallelogram groove 6391 serve as motion direction conversion elements; the movable column 639, the telescopic spring 6310, the fixed frame 633, and the floating pressure roller 634 serve as pressure adjustment actuators. The various structures are linked in sequence, so that when the sheet metal is offset to one side, the floating pressure roller 634 on that side can automatically reduce the clamping force on the sheet metal, while the opposite side maintains a larger clamping traction effect. This forms a differential friction traction between the left and right sides, so that the sheet metal automatically returns to the center line during continuous conveying. This correction method can avoid scratches, curling, or indentations caused by the direct hard pushing of the sheet metal edge by the traditional limit plate or push plate, and can produce a flexible correction effect when the sheet metal is slightly offset, improving the positional stability and forming accuracy of the metal sheet before entering the cold bending roller 8.

[0036] In addition, the infrared displacement sensor 6311 is electrically connected to the motor 74 and the drive module 9 respectively. The infrared displacement sensor 6311 is installed on the side wall of the movable column 639 and electrically connected to the motor 74. It is used to detect the moving distance of the slider 638. During normal conveying, the slider 638 only produces a small displacement. The displacement detected by the infrared displacement sensor 6311 is within the set range. The motor 74 continues to work, and the conveying roller 73 continues to drive the plate forward. When the plate deviates to the left or right, the side of the plate presses against the guide wheel 621 on the corresponding side. The guide wheel 621 drives the slider 638 to move along the slide groove 6391 through the rotating rod 623, the lever 624 and the slide plate 637. At this time, the moving distance of the slider 638 can be reversed. The movement distance of the slider 638 does not exceed the set value, indicating that the material is still within the correctable range. The floating pressure roller 634 continues to correct the material through pressure changes. If the movement distance of the slider 638 exceeds the set value, it indicates that the material is too misaligned, and there is a risk of jamming, edge curling, or oblique entry into the cold bending roller 8. At this time, the infrared displacement sensor 6311 sends a stop signal to the motor 74 and the drive module 9, causing the motor 74 to stop working, thereby stopping the rotation of the conveying roller 73 and preventing the material from continuing to be conveyed at an angle, which could cause damage or affect the quality of cold bending. Through this setting, automatic correction can be performed when the material is slightly misaligned, and timely shutdown protection can be performed when the material is seriously misaligned, achieving a synergistic effect of correction and protection.

[0037] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0038] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
