Description

Technical Field

[0001] This utility model relates to the field of metal plate leveling technology, and more specifically to a directional guiding device for a precision leveling machine for ultra-thin metal plates. Background Technology

[0002] In the field of precision metal processing and manufacturing, the application of ultra-thin metal sheets is becoming increasingly widespread, such as shielding covers for electronic components, backing plates for precision instruments, and flexible circuit boards. These products not only have extremely high requirements for the flatness of the materials, but also have almost stringent standards for the smoothness and integrity of their surfaces. Any tiny scratch, dent, or wire drawing may lead to a decrease in product performance or even direct scrapping.

[0003] Precision leveling machines are key equipment for ensuring the flatness of ultra-thin sheets. They use multiple leveling rollers to repeatedly bend the sheet to eliminate internal stress. However, before the sheet enters the leveling machine, it must pass through a guide device, which is used to accurately and smoothly feed the sheet into the leveling roller system.

[0004] A search revealed Chinese patent CN215696962U, which discloses a metal plate leveling machine. This metal plate leveling machine can effectively realize the leveling process of metal plates, and has high leveling efficiency, good leveling effect, and high practicality. However, if there is a slight deviation in the initial feeding direction when the plate enters the leveling roller system, it will be rapidly amplified during the high-speed feeding process, causing the plate to deviate, snake, or even collide with the frame in the leveling machine, affecting the uniformity and stability of the leveling quality. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a directional guide device for a precision leveling machine for ultra-thin metal sheets, so as to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a directional guide device for a precision leveling machine for ultra-thin metal sheets, comprising a worktable and a leveling machine body detachably connected to the upper surface of the worktable by bolts. A side support is fixedly connected to one side of the worktable. Side plates are fixedly connected to the crossbars on both sides of the side support. Multiple slide rods are fixedly connected between the two side plates. Two slide frames are slidably connected to the multiple slide rods by sliding sleeves. Vertical clamping rollers extending downward are rotatably connected to one side of the bottom of each of the two slide frames by bearing seats for limiting the two sides of the metal sheet. Multiple three-pronged slide blocks are inserted through and slidably connected to the two slide frames. Horizontal clamping rollers for pressing the upper surface of the metal sheet are fixedly connected between the inner walls of the two sides of the three-pronged slide blocks located below the slide frames. A secondary guide assembly is provided on the upper surface of the worktable, located between the leveling machine body and the side support.

[0007] As a further embodiment of this utility model, the secondary guide assembly includes a fixed platform fixedly connected to the upper surface of the workbench, and an adjustable side stop is fixedly connected to the upper surface of the fixed platform.

[0008] As a further embodiment of this utility model, an inclined surface is provided on one side of the side block and at a position close to the side bracket.

[0009] As a further embodiment of this utility model, a bidirectional lead screw is rotatably connected between the two side plates via a bearing seat. The bidirectional lead screw passes through two slides and is threadedly connected to the slides via a threaded cylinder. A drive motor that causes the bidirectional lead screw to rotate axially is fixedly connected to one side of one of the side plates.

[0010] As a further embodiment of this utility model, the multiple three-pronged slides on the same side are connected by a connecting plate. A cylinder is fixedly connected to the top outer wall of the slide frame. The bottom end of the cylinder piston rod passes through the slide frame and is fixed to the upper surface of the frame formed by the connecting plate and the three-pronged slides.

[0011] As a further embodiment of this utility model, two card seats are snapped onto the two sides of the top frame of the side bracket, and multiple support wheels are rotatably connected between the inner walls of the two card seats through bearing seats to support the conveyed metal plate.

[0012] As a further embodiment of this invention, the roller surface of the vertical clamping roller is covered with a coating layer made of flexible material.

[0013] As a further embodiment of this utility model, the top of the support wheel, the upper surface of the fixed platform, and the top of the extrusion roller at the bottom of the leveling machine body are located on the same horizontal plane.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. This utility model uses vertical and horizontal clamping rollers to constrain the sheet material from both sides and above, effectively preventing deviation and serpentine phenomena during high-speed feeding, and ensuring the uniformity and stability of the leveling quality.

[0016] 2. This utility model uses a cylinder to drive multiple transverse clamping rollers to press down, applying uniform vertical pressure to the upper surface of the sheet material, forcing the sheet material to enter the leveling machine in a flat posture. Together with the lateral vertical clamping rollers, they form a stable guide channel, solving the problems of jamming and impact caused by the initial unevenness of the sheet material, and ensuring the continuity and stability of the feeding process.

[0017] 3. By setting the top of the support wheel, the upper surface of the fixed platform, and the top of the extrusion roller at the bottom of the leveling machine body on the same horizontal plane, this utility model creates a flat and continuous support benchmark for sheet material conveying, effectively preventing unstable phenomena such as sagging and bouncing of ultra-thin sheets due to their own weight or conveying force, and providing reliable initial conditions for subsequent precision guidance and leveling.

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Reference Figures 1-5This utility model provides a directional guide device for a precision leveling machine for ultra-thin metal sheets, including a worktable 1 and a leveling machine body 2 detachably connected to the upper surface of the worktable 1 by bolts. A side support 3 is fixedly connected to one side of the worktable 1 by bolts. A side plate 5 is fixedly connected to the crossbars on both sides of the side support 3 by a retaining ring 4. A plurality of slide rods 9 are fixedly connected between the two side plates 5 by bolts. Two slide frames 10 are slidably connected to the plurality of slide rods 9 by a sliding sleeve. A downwardly extending vertical clamping roller 11 is rotatably connected to one side of the bottom of the two slide frames 10 by a bearing seat. The roller surface of the vertical clamping roller 11 is covered with a coating layer made of flexible material for limiting the two sides of the metal sheet.

[0026] The leveling machine body 2 includes a frame, leveling roller group, support roller device and pressing / adjusting mechanism, etc. Through its precisely configured roller system, it applies a repeated elastoplastic bending with decreasing curvature to the board material, causing the length of its internal fiber layer to redistribute and tend to be uniform, thereby completely eliminating uneven defects such as wavy edges, sickle bends, and warping, and obtaining products with high flatness.

[0027] The vertical clamping roller 11 and the horizontal clamping roller 13 work together to constrain the sheet material from both sides and above, effectively preventing deviation and serpentine phenomena during high-speed feeding, and ensuring the uniformity and stability of the leveling quality.

[0028] A bidirectional lead screw 14 is rotatably connected between the two side plates 5 via a bearing seat. The bidirectional lead screw 14 passes through the two slides 10 and is threadedly connected to the slides 10 via a threaded cylinder. A drive motor 15 that causes the bidirectional lead screw 14 to rotate axially is fixedly connected to one side of one of the side plates 5 by bolts.

[0029] It should be noted that the drive motor 15 is existing technology, which is a servo motor with an encoder. The number of rotations and rotation angle of the motor output shaft are controllable and have high precision. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0030] Start the drive motor 15 to drive the bidirectional lead screw 14 to rotate, since the two slides 10 are connected to the bidirectional lead screw 14 by threads.

[0031] In this application, the inner wall of the threaded cylinder on the slide 10 is provided with an annular groove, and a nylon 66 damping ring with a Shore hardness of 85A is embedded in the groove. The continuous axial clamping force generated by its elastic deformation forms a helical angle interference fit with the surface of the double-acting screw 14 at 15°-20°. When the threaded pair is subjected to axial vibration load, the nylon insert can generate a maximum elastic compression of 0.3mm, which increases the friction coefficient between the thread contact surfaces from 0.15 to 0.68 (tested according to ASTM D1894 standard), effectively suppressing the loosening displacement caused by thread springback.

[0032] Width adjustment: The two slides 10 move synchronously towards or away from each other under the guidance of the slide rod 9, thereby adjusting the distance between the two slides 10, which can quickly adapt to plates of different widths. Lateral limit: After adjustment, the two sides of the plate just enter the vertical clamping rollers 11 on both sides.

[0033] The vertical clamping roller 11 can rotate freely, and the flexible material (such as polyurethane) covering its rollers forms a rolling flexible contact with the side of the sheet.

[0034] Multiple three-pronged slide blocks 12 are threaded and slidably connected on the two slide blocks 10. A transverse clamping roller 13 for pressing the upper surface of the metal plate is fixedly connected between the inner walls of the two sides of the three-pronged slide blocks 12 located below the slide blocks 10 by bolts. A secondary guide assembly 6 is provided on the upper surface of the worktable 1 and located between the leveling machine body 2 and the side support 3.

[0035] In this utility model, the secondary guide assembly 6 includes a fixed platform 18 that is fixedly connected to the upper surface of the worktable 1 by bolts, and an adjustable side stop 19 is fixedly connected to the upper surface of the fixed platform 18 by bolts.

[0036] Furthermore, a slope 20 is provided on one side of the side block 19 and on the side close to the side bracket 3.

[0037] After passing through the guide channel, the sheet material enters the final secondary guide assembly 6. The inclined surface 20 of the side stop 19 near the entrance acts as a flared mouth, which can easily correct any possible minor centering errors and smoothly guide the sheet material into the precise positioning gap. This allows for the final precise positioning of the sheet material, ensuring that it enters the roller system of the leveling machine body 2 in an absolutely ideal centering state.

[0038] In this utility model, multiple three-pronged slide blocks 12 on the same side are connected by connecting plates 16. A cylinder 17 is fixedly connected to the top outer wall of the slide frame 10 by bolts. The bottom end of the piston rod of the cylinder 17 passes through the slide frame 10 and is fixed to the upper surface of the frame formed by the connecting plates 16 and the three-pronged slide blocks 12.

[0039] It should be noted that: Cylinder 17 is a power actuator that converts the pressure energy of compressed air into mechanical energy. By controlling the gas in and out, it drives the piston to perform linear reciprocating motion. It can be used in conjunction with a magnetic switch, proximity switch or photoelectric switch to achieve precise control of the extension and retraction displacement of the piston rod of cylinder 17. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0040] When the cylinder 17 is activated, its piston rod pushes the connecting plate 16 and the multiple three-pronged slide blocks 12 connected to it downwards, thereby driving the transverse clamping roller 13 installed at the lower part of the three-pronged slide block 12 to move downwards until it gently presses against the upper surface of the sheet material. The vertical clamping roller 11 and the transverse clamping roller 13 cooperate with each other to constrain the sheet material from both vertical and horizontal directions, thus achieving precise directional conveying.

[0041] The cylinder 17 drives multiple transverse clamping rollers 13 to press down, applying uniform vertical pressure to the upper surface of the sheet material, forcing the sheet material to enter the leveling machine in a flat posture. Together with the lateral vertical clamping rollers 11, they form a stable guide channel, solving the problems of jamming and impact caused by the initial unevenness of the sheet material, and ensuring the continuity and stability of the feeding process.

[0042] In this utility model, two card seats 7 are snapped onto the two sides of the top frame of the side bracket 3. Multiple support wheels 8 are rotatably connected between the inner walls of the two card seats 7 via bearing seats to support the conveyed metal plate.

[0043] Furthermore, the top of the support wheel 8, the upper surface of the fixed platform 18, and the top of the bottom extrusion roller of the leveling machine body 2 are located on the same horizontal plane.

[0044] The ultra-thin metal sheet to be leveled is first conveyed to multiple support rollers 8 on the top of the side support 3. The top of the support rollers 8, the upper surface of the fixed platform 18, and the top of the bottom extrusion roller of the leveling machine body 2 are on the same horizontal plane. This creates a flat and continuous support reference surface for the sheet, effectively preventing the sheet from sagging due to its own weight and causing the initial position to shift.

[0045] By setting the top of the support wheel 8, the upper surface of the fixed platform 18, and the top of the bottom extrusion roller of the leveling machine body 2 on the same horizontal plane, a flat and continuous support benchmark is constructed for the sheet material conveying, which effectively prevents the ultra-thin sheet material from sagging, bouncing and other unstable phenomena due to its own weight or conveying force, and provides reliable initial conditions for subsequent precision guidance and leveling.

[0046] The use of this utility model involves the following steps:

[0047] S1: The ultra-thin metal sheet to be leveled is first conveyed to multiple support rollers 8 on the top of the side support 3. The top of the support rollers 8, the upper surface of the fixed table 18 and the top of the bottom extrusion roller of the leveling machine body 2 are on the same horizontal plane. This creates a flat and continuous support reference surface for the sheet, effectively preventing the sheet from sagging due to its own weight and causing the initial position to shift.

[0048] S2: Start the drive motor 15 to drive the bidirectional lead screw 14 to rotate. Since the two slides 10 are connected to the bidirectional lead screw 14 by threads, the width can be adjusted by the two slides 10 moving synchronously towards or away from each other under the guidance of the slide rod 9, thereby adjusting the distance between the two slides 10. This can quickly adapt to plates of different widths. After adjustment, the two sides of the plate just enter the vertical clamping rollers 11 on both sides.

[0049] S3: Subsequently, the cylinder 17 is activated, and its piston rod pushes the connecting plate 16 and the multiple three-pronged slide blocks 12 connected to it downward as a whole, thereby driving the transverse clamping roller 13 installed at the lower part of the three-pronged slide block 12 to move downward until it is gently pressed against the upper surface of the sheet material. The vertical clamping roller 11 and the transverse clamping roller 13 cooperate with each other to constrain the sheet material from both vertical and horizontal directions, thereby achieving precise directional conveying.

[0050] S4: After passing through the guide channel, the sheet material enters the final secondary guide assembly 6. The inclined surface 20 of the side stop 19 near the entrance acts as a flared mouth, which can easily correct any possible minor centering errors and smoothly guide the sheet material into the precise positioning gap. This allows for the final precise positioning of the sheet material, ensuring that it enters the roller system of the leveling machine body 2 in an absolutely ideal centering state.

[0051] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationship.
