Description

Technical Field

[0001] This invention relates to the field of copper strip processing, and more particularly to a raw material leveling device for copper strip processing. Background Technology

[0002] During the rolling, winding, storage, transportation, and processing of copper and copper alloy strips, various plastic deformations inevitably occur, mainly manifested as regular / irregular bends along the length direction, wavy bends, edge warping, and unevenness such as local bulges or depressions. These geometric defects not only directly affect the appearance quality of the product but also severely restrict the accuracy and yield of subsequent precision processing steps (such as etching, stamping, and welding). Traditional leveling methods mostly rely on single-function rolling equipment or manual hammering for straightening. While the former can improve macroscopic curvature, it is difficult to eliminate local micro-undulations and has rough control over the force applied to the material, easily inducing secondary stress or surface scratches; the latter is inefficient, inconsistent, highly dependent on personnel skills, and cannot meet the needs of large-scale production. Especially for copper strips of moderate thickness with a significant tendency for work hardening, relying solely on mechanical external force for leveling easily produces springback, requiring repeated processing, which damages the surface condition of the material and reduces production efficiency.

[0003] Therefore, in order to address the above problems, a raw material leveling device for copper strip processing is now being developed. Summary of the Invention

[0004] In order to overcome the shortcomings of existing devices, the present invention provides a raw material leveling device for copper strip processing.

[0005] The technical solution of this invention is:

[0007] Installation platform;

[0008] A limiting plate is installed on the upper part of the mounting platform;

[0009] A fixing plate is installed on the front and rear sides of the mounting platform;

[0010] A leveling mechanism is installed between the limiting plate and the mounting platform;

[0011] A feeding mechanism is installed on the right side of the mounting platform.

[0012] Optionally, the leveling mechanism includes:

[0013] The first drive motor is located on the upper left side of the mounting platform;

[0014] A lead screw is mounted on the output shaft of the first drive motor;

[0015] A movable seat is slidably mounted on the limiting plate, and the movable seat is threadedly connected to the lead screw;

[0016] A hydraulic cylinder is mounted on the bottom of the movable plate;

[0017] A lifting frame is installed between the telescopic ends of the hydraulic cylinder. The lifting frame has protrusions on both the left and right sides. The bottom of the protrusions is a flat structure that can fit with the conveyor belt.

[0018] A leveling roller is rotatably connected to the lower part of the lifting frame.

[0019] Optionally, the feeding mechanism includes:

[0020] The lifting frame is slidably connected to the lower right side of the mounting platform;

[0021] A second drive motor is mounted on the mounting platform;

[0022] The feeding roller is connected to the output shaft of the second drive motor and is rotatably connected to the mounting platform.

[0023] Optionally, it further includes a positioning mechanism, the positioning mechanism comprising:

[0024] The positioning components are slidably installed on the front and rear parts of the mounting platform. The inner sides of the positioning components are all obtuse-angled bent structures, and a guide entrance is formed between the right sides of the two positioning components.

[0025] A limiting rod is mounted on the positioning member and is slidably connected to the mounting platform.

[0026] A first spring is wound around the outside of the corresponding limiting rod and connected to the limiting rod and the outside of the mounting platform.

[0027] Optionally, it also includes a locking mechanism, the locking mechanism comprising:

[0028] A locking frame is slidably mounted on the fixed plate. The locking frame is used to lock the adjacent positioning members. The locking frame is limited by the compression of the lifting frame.

[0029] The second spring is installed between the locking bracket and the fixing plate.

[0030] Optionally, it further includes a heating mechanism, which includes:

[0031] Support member, which is installed on the left side of the lifting frame;

[0032] An auxiliary heating component is installed between the support member and the lifting frame to preheat and soften the copper strip.

[0033] Optionally, it also includes a cleaning mechanism, which includes:

[0034] The fan is mounted on the lifting frame;

[0035] The air duct is installed inside the lifting frame and connected to the fan.

[0036] Optionally, the bottom of the leveling roller is flush with the bottom of the raised sections on the left and right sides of the lifting frame.

[0037] Optionally, the lower right side of the lifting frame has an inclined guide structure.

[0038] Optionally, the bottom of the locking frame is L-shaped.

[0039] By adopting the above technical solution, the present invention has the following advantages compared with the prior art:

[0040] 1. This invention constructs an integrated channel of "introduction-centering-positioning-dynamic correction" by precisely coordinating the inclined guide and height adaptive clamping of the feeding mechanism, the obtuse angle guide entrance of the positioning mechanism, and the elastic closed link. This ensures that the copper strip enters the leveling station with a precise center position and stable posture, greatly reducing deviation and friction loss. The leveling mechanism creatively integrates the static pressure of the hard plane on both sides of the lifting frame with the rotating rolling of the leveling roller, and uses the wide stepless displacement driven by the screw to cover the entire width of the copper strip.

[0041] 2. This invention integrates the automatic release / locking logic of the locking mechanism to lock the positioning component to avoid copper strip feeding in the non-leveling state. During operation, the constraint is released to enable elastic follow-up correction, protecting the strip edge and enhancing system reliability. The auxiliary heating mechanism uses the pre-softening treatment before the lifting frame is pressed down to reduce the yield strength of the copper strip, making subsequent leveling easier and reducing internal residual stress.

Detailed Implementation

[0051] 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, and 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.

[0052] Example 1

[0053] A raw material leveling device for copper strip processing, such as Figures 1-8 As shown, it includes an installation platform 1, a limiting plate 2 installed on the upper part of the installation platform 1, a fixing plate 3 installed on the front and rear sides of the installation platform 1, a leveling mechanism 4 installed between the limiting plate 2 and the installation platform 1, and a feeding mechanism 5 installed on the right side of the installation platform 1.

[0054] The leveling mechanism 4 includes a first drive motor 41, which is located on the upper left side of the mounting platform 1. A lead screw 42 is mounted on the output shaft of the first drive motor 41. A movable seat 43 is slidably mounted on the limiting plate 2 and is threadedly connected to the lead screw 42. A hydraulic cylinder 44 is mounted at the bottom of the movable plate. A lifting frame 45 is mounted between the extension and retraction ends of the hydraulic cylinder 44. The lifting frame 45 has protrusions on both the left and right sides. The bottom of the protrusions is a flat structure that can fit with the conveyor belt. A leveling roller 46 is rotatably connected to the lower part of the lifting frame 45. The bottom of the leveling roller 46 is flush with the bottom of the protrusions on the left and right sides of the lifting frame 45.

[0055] The feeding mechanism 5 includes a lifting frame 51, which is slidably connected to the lower right side of the mounting platform 1. The lower right side of the lifting frame 51 has an inclined guide structure. The second drive motor 52 is mounted on the mounting platform 1, and the feeding roller 53 is connected to the output shaft of the second drive motor 52. The feeding roller 53 is rotatably connected to the mounting platform 1.

[0056] It should be noted that this equipment is a precision and efficient mechanical system designed to eliminate various plastic bending deformations of copper strips during winding, transportation, or pre-processing, including common wavy bends, warps, and local undulations, restoring them to a flat state that meets process requirements. The leveling process begins at the feeding mechanism 5 on the right side of the equipment. After the leveled copper strip coil is placed at the feeding station, the head of the copper strip is manually or by an auxiliary device fed into the gap entrance formed by the top of the feeding roller 53 and the lifting frame 51. The core power source of the feeding mechanism 5—the second drive motor 52—starts and directly drives the cylindrical feeding roller 53 to rotate through the output shaft. The surface of the feeding roller 53... The mask has a sufficient coefficient of friction to establish reliable friction between it and the copper strip, thereby continuously pulling and conveying the copper strip forward at a constant rate. The lifting frame 51, located below the feeding roller 53 and slidably connected to the lower side of the mounting platform 1, has a cleverly designed inclined guide structure for its feeding section. This inclined surface not only serves as a guide, ensuring the copper strip enters the equipment smoothly and without obstruction, but more importantly, the overall height of the lifting frame 51 can automatically adapt to the initial thickness and deformation degree of the copper strip. After adjustment, a suitable clamping inlet is formed between the top of the lifting frame 51 and the rotating feeding roller 53. This inlet firmly clamps the copper strip, providing stable traction and preventing slippage. On the other hand, a slight vertical constraint force is applied to the incoming copper strip, which plays a preliminary straightening and correction role, laying the foundation for subsequent fine leveling. Under the stable traction of the feeding roller 53, the copper strip is continuously fed into the leveling station located in the core area of ​​the equipment through a precisely designed path. After leaving the feeding mechanism 5, the copper strip immediately enters the leveling working channel formed by the limiting plate 2 installed on the upper part of the mounting platform 1 and the sturdy fixing plates 3 on the front and rear sides. The first drive motor 41 integrated on the upper left side of the mounting platform 1 starts, and its output shaft directly drives the lead screw 42 to rotate. The moving seat 43, which forms a threaded engagement relationship with the lead screw 42, is installed on the guide rail preset on the limiting plate 2. Therefore, When the lead screw 42 rotates under the drive of the motor, the thread engagement mechanism precisely converts the rotational motion into the linear translational motion of the moving seat 43 along the guide rail. By controlling the direction and duration of the first drive motor 41, the moving seat 43 can achieve stepless smooth movement within the effective width of the copper strip, accurately positioning itself at any point where a leveling force needs to be applied. After the moving seat 43 completes its positioning, the hydraulic cylinder 44 mounted at its bottom begins to operate. The telescopic end of the hydraulic cylinder 44 extends downward, driving the lifting frame 45 connected between the two telescopic ends to move vertically downward as a whole. The lifting frame 45 has a unique design, with outwardly extending, finely machined, robust protrusions on its left and right bottom sides. The lower surfaces of these protrusions are perfectly horizontal, smooth, and finely ground planes with sufficient area to provide stable support.When the lifting frame 45 moves into position, the bottom surfaces of the two raised planar surfaces will smoothly and completely contact and press against the copper strip surface directly below them, providing uniform static pressure. This direct planar contact and static pressure method is particularly adept at handling small-area "point-like" or tiny "block-like" depressions, undulations, or local warping on the copper strip. Under strong and continuous pressure, the hard planes cause the copper strip to follow the absolute flatness reference of the raised bottom surface of the lifting frame 45 in the local area of ​​pressure, forcing the raised area to produce a slight plastic yield and collapse, while the concave area is rigidly supported and extended. The process involves unfolding the surface to eliminate irregular deformation in the local area, restoring flatness, and completing static pressure straightening. As the lifting frame 45 continues to move, the leveling roller 46, installed at the lower part of the lifting frame 45 and located between the two protrusions, begins to play a crucial role. This leveling roller 46 is rotatably connected to the lifting frame 45 via bearings. Its lowest point is precisely designed to be on the same absolute horizontal plane as the lower bottom surface of the left and right protrusions of the lifting frame 45. When the lifting frame 45 lowers the leveling roller 46 to the working position, the rolling surface of the leveling roller 46 contacts the copper strip and... Under the controllable additional pressure provided by gravity and hydraulic cylinder 44, a vertically downward pressure is applied to the surface of the copper strip. The leveling roller 46 rotates freely due to friction with the copper strip. This rotating rolling method is key to efficiently leveling large-area bending deformations (such as wavy bends or regular bends). Its core mechanism lies in the precise control of the bending moment: when the copper strip enters the rolling contact area (entry arc), it is subjected to the upward reaction force of the leveling roller 46, which makes it bear the bending stress that reduces the curvature. When it leaves the rolling contact area (exit arc), it mainly bears the bending stress that increases the curvature. The reverse bending stress is precisely controlled by the pressure (i.e. bending deformation) applied by the leveling roller 46 and the multiple, repeated rolling cycles (moving seat 43 moves in coordination with copper strip feeding). The copper strip is like undergoing multiple micro-folds, and the residual stress accumulated inside is gradually released, neutralized and reorganized, and finally reaches a flat and stable state. Compared with static pressure, the force applied in the rolling process is more linear, continuous and smooth, and the applied bending deformation is uniform and controllable, effectively avoiding the risk of local overstress in the material. It is especially good at handling bending deformation and uneven distribution in the length direction.

[0057] Example 2

[0058] Based on embodiment 1, a positioning mechanism 6 is also included. The positioning mechanism 6 includes a positioning member 61, which is slidably installed on the front and rear parts of the mounting platform 1. The inner sides of the positioning member 61 are all obtuse angle bending structures. A guide entrance is formed between the right sides of the two positioning members 61. A limiting rod 62 is installed on the positioning member 61 and is slidably connected to the mounting platform 1. A first spring 63 is wrapped around the outside of the corresponding limiting rod 62 and is connected to the limiting rod 62 and the outside of the mounting platform 1.

[0059] It should be noted that in the precise operation of the copper strip leveling equipment, the positioning mechanism 6 ensures accurate initial copper strip feeding, stable running trajectory, and effective overcoming of slight lateral movement. Its working principle cleverly integrates mechanical guidance, elastic adaptation, and reliable limiting. The core of this mechanism lies in two symmetrically arranged positioning components 61, which are installed on the front and rear sides of the mounting platform 1 through a sliding connection structure. The inner side of the positioning component 61 is designed as an obtuse-angled bend with a specific inclination angle. These two bends are arranged opposite each other on the right side of the positioning component 61, forming a "trumpet-shaped" guide entrance that gradually narrows from wide to narrow. When the feeding mechanism conveys the copper strip forward, the front and rear edges of the copper strip first contact this entrance formed by the obtuse-angled bend. The contact point formed by the bend and the edge of the copper strip naturally generates a component force from the outside to the inside, i.e., a centripetal guiding force. This force automatically pushes the copper strip, which has a slightly different width or a slightly deviated initial feeding position, toward the central axis of the leveling channel, achieving initial centering correction. After the centering is completed, the copper strip enters the parallel channel formed by the straighter inner parts of the front and rear positioning components 61. The guide section is parallel to the edge of the copper strip and maintains a precisely set micro-gap. This parallel section provides a smooth, unobstructed longitudinal path for the copper strip as it moves forward, while its sidewalls serve as a rigid reference surface, effectively restraining any lateral displacement that may occur during the forward movement of the copper strip. Supporting the sliding performance of the positioning element 61 is a limiting rod 62 slidably connected to the mounting platform 1. This rod provides precise guidance for the movement of the positioning element 61 and restricts its path. A first spring 63 is mounted around the outer side of the limiting rod 62, with its two ends abutting against the positioning element 61 and... On the outside of mounting platform 1, this spring system continuously applies an elastic preload force pointing towards the center line of the copper strip to the positioning component 61 during the leveling process. When the copper strip moves slightly laterally due to uneven material or external interference during the conveying or leveling process, the positioning component 61 will overcome the spring force and move slightly outward as the edge of the copper strip is squeezed. At this time, the spring is compressed and stores energy. Once the disturbance disappears, the spring immediately releases the stored energy, pushes the positioning component 61 back to the preset distance, and gently but firmly pushes the copper strip back to the center position, always maintaining the copper strip in the correct position.

[0060] It also includes a locking mechanism 7, which includes a locking frame 71. The locking frame 71 is slidably mounted on the fixed plate 3. The bottom of the locking frame 71 is L-shaped. The locking frame 71 is used to lock the adjacent positioning member 61. The locking frame 71 is limited by the compression of the lifting frame 45. The second spring 72 is installed between the locking frame 71 and the fixed plate 3.

[0061] It should be noted that in the initial state, the second spring 72 is under compression, and the positioning component 61 is limited by the locking frame 71 and cannot move inward. At this time, the copper strip can pass through normally, avoiding wear on the edge of the copper strip. As the lifting frame 45 begins to move downward, the locking frame 71 will disengage from the limit. Under the action of the second spring 72, the locking frame 71 will slide downward, thereby releasing the locking of the positioning component 61. The positioning component 61 will then reset and complete the correction and positioning of the copper strip.

[0062] It also includes a heating mechanism 8, which includes a support member 81. The support member 81 is installed on the left side of the lifting frame 45, and an auxiliary heating component 82 is installed between the support member 81 and the lifting frame 45 for preheating and softening the copper strip.

[0063] It also includes a cleaning mechanism 9, which includes a fan 91. The fan 91 is installed on the lifting frame 51, and the air duct 92 is installed inside the lifting frame 51 and connected to the fan 91.
