Description

Technical Field

[0001] This utility model relates to the field of metal coil processing technology, specifically a metal coil flattening device. Background Technology

[0002] In the metal processing industry, metal coil raw materials are prone to deformation such as warping and wrinkling during storage and transportation due to stress release and external extrusion. They need to be processed by a flattening device before they can enter the subsequent processing steps.

[0003] Currently available metal coil flattening devices have many shortcomings: Firstly, the flattening direction is singular. Most devices only use a unidirectional flattening structure, either using a pressure roller parallel to the conveying direction for forward flattening or using a pressure roller perpendicular to the conveying direction for transverse flattening. This cannot simultaneously eliminate the stress deformation of the metal strip in two perpendicular directions, resulting in insufficient flatness of the metal strip after flattening. Some areas still have fine wrinkles, which affects the processing accuracy of subsequent stamping, welding and other processes. Secondly, the flattening components have poor stability. In existing transverse flattening components, the transverse movement mechanism is mostly driven by the hydraulic cylinder to move the transverse block directly. It lacks a guide and limit structure. When the transverse block moves, it is easy to deviate, resulting in uneven contact force between the transverse flattening roller and the metal strip, and large fluctuations in the flattening effect. When the lifting mechanism drives the flattening roller to rise and fall, it often shakes due to the lack of vertical guidance, which further reduces the flattening accuracy. Thirdly, the processes are loosely connected. In most devices, the flattening and cutting processes are independent. After the metal strip is flattened, it needs to be manually transferred to the cutting equipment, which not only increases labor costs but also extends the processing cycle. Furthermore, the metal strip is susceptible to secondary deformation due to external impacts during transfer, affecting product quality. These problems restrict the production efficiency and product quality of metal processing, and there is an urgent need for a structurally optimized metal coil flattening device to solve them.

[0005] 2. Technical Solution: To achieve the above objectives, this utility model provides the following technical solution: a metal coil flattening device, comprising an unwinding mechanism, a tension roller, a guide roller, a conveyor, and a cutting platform arranged sequentially along the metal strip conveying path. The conveyor surface is provided with a transverse flattening component and a forward flattening component for flattening the metal strip. The unwinding mechanism is used to release the metal coil raw material. The tension roller and the guide roller are sequentially connected between the unwinding mechanism and the conveyor to tension and guide the direction of the metal strip. The metal strip conveyed by the conveyor is flattened sequentially by the transverse flattening component and the forward flattening component and then conveyed to the cutting platform. The cutting platform is provided with a cutting mechanism.

[0006] Furthermore, the transverse flattening assembly includes a mounting frame fixedly disposed on one side of the conveyor. A transverse hydraulic cylinder is fixedly mounted on the mounting frame. A transverse block is fixedly connected to the output end of the transverse hydraulic cylinder. A lifting hydraulic cylinder is fixedly mounted to the lower end of the transverse block. A U-shaped frame is fixedly connected to the output end of the lifting hydraulic cylinder. A transverse flattening roller is rotatably mounted on the open end of the U-shaped frame. The axis of the transverse flattening roller is parallel to the conveying direction of the conveyor. The piston rod of the transverse hydraulic cylinder moves in a direction perpendicular to the conveying direction of the conveyor.

[0007] Furthermore, a guide rail is fixedly installed in the mounting bracket along the horizontal direction, and a slider is fixedly installed on the side of the transverse block facing the guide rail, with the slider slidingly engaging with the guide rail.

[0008] Furthermore, a fixing plate is fixedly installed at the lower end of the cylinder body of the lifting hydraulic cylinder, and a guide shaft is fixedly installed on the upper end face of the U-shaped frame in the vertical direction.

[0009] Furthermore, the forward flattening assembly includes two support plates symmetrically fixed on both sides of the conveyor's conveying direction. Each support plate has several support shafts fixedly connected to its upper surface in the vertical direction. All support shafts have a common mounting beam fixedly installed at their upper ends.

[0011] 3. Beneficial effects: Compared with the prior art, the present invention provides an adjustable magnetic stirrer, the specific details of which are as follows: (1) This utility model uses a combination of a transverse flattening component and a forward flattening component. The transverse flattening roller rolls along the vertical conveying direction to eliminate the warping of the metal strip in the vertical conveying direction. The forward flattening roller rolls along the conveying direction to eliminate the deformation in the conveying direction. Bidirectional flattening can simultaneously handle the stress in two vertical directions of the metal strip, greatly improving the flatness and solving the shortcomings of traditional unidirectional flattening.

[0012] (2) In the transverse flattening assembly of this utility model, the guide rail and the slider guide the transverse block to move smoothly and avoid deviation; the guide shaft and the guide groove restrict the vertical lifting trajectory of the U-shaped frame to prevent shaking; in the forward flattening assembly, the two relative lifting hydraulic cylinders move synchronously to ensure that the forward flattening roller is always horizontal. With the guidance of the guide hole and the support shaft, the lifting of the mounting support is further guaranteed to be smooth. The multiple stabilizing structures make the flattening force uniform and the flattening accuracy significantly improved.

[0013] (3) The present invention is provided with unwinding, flattening and cutting structures along the conveying path. The metal strip is continuously conveyed by the conveyor and flattened before entering the cutting platform for cutting by the cutting mechanism. No manual transfer is required, which shortens the processing cycle, avoids secondary deformation, is suitable for industrial continuous production, reduces labor costs, and improves production efficiency and product quality.

[0022] The forward flattening assembly 6 includes two support plates 61 symmetrically fixed on both sides of the conveyor 4 in the conveying direction. Each support plate 61 has several support shafts 66 fixedly connected to its upper surface in the vertical direction. A mounting beam 62 is fixedly mounted on the upper end of all the support shafts 66. Several lifting hydraulic cylinders 63 are fixedly fixed at equal intervals along the conveying direction of the conveyor 4 on the mounting beam 62. Each lifting hydraulic cylinder 63 has a mounting support 64 fixedly mounted at its output end. A forward flattening roller 65 is rotatably mounted between every two opposing mounting supports 64, and the axis of the forward flattening roller 65 is perpendicular to the conveying direction of the conveyor 4. Each mounting support 64 of the forward flattening assembly 6 has a guide hole 67 that penetrates the mounting support 64 in the vertical direction, and the support shaft 66 slides through the corresponding guide hole 67.

[0023] Working principle: The metal coil material is installed on the reel of the unwinding mechanism 1. The unwinding mechanism 1 is started, and the metal coil material is slowly released as a metal strip. The released metal strip is first conveyed to the tension roller 2. The tension roller 2 applies stable tension to the metal strip through a preset tension adjustment mechanism to prevent the metal strip from loosening and causing subsequent flattening and deviation. Then the metal strip enters the guide roller 3. The guide roller 3 adjusts the conveying angle of the metal strip by rotating itself, so that the metal strip is smoothly conveyed to the conveying surface of the conveyor 4 in a horizontal posture. The conveyor 4 is started and drives the metal strip to move along the conveying path at a preset speed. Lateral flattening stage: When the front end of the metal strip is conveyed to directly below the lateral flattening assembly 5, the lateral flattening assembly 5 is activated. The piston rod of the lifting hydraulic cylinder 56 extends downward, driving the U-shaped frame 57 connected to its output end to descend vertically. The lateral flattening roller 58, which is rotatably installed at the open end of the U-shaped frame 57, moves downward accordingly until the lateral flattening roller 58 contacts the upper surface of the metal strip and applies a preset flattening force. During this process, the guide shaft 510 at the upper end of the U-shaped frame 57 slides vertically synchronously along the guide groove of the fixed plate 59, restricting the U-shaped frame 57's movement. The swaying of the frame 57 ensures uniform contact between the transverse flattening roller 58 and the metal strip. At the same time, the piston rod of the transverse hydraulic cylinder 52 reciprocates along the conveying direction of the vertical conveyor 4, driving the transverse block 53 connected to its output end to move. The slider 55 on the side of the transverse block 53 slides smoothly along the guide rail 54 in the mounting frame 51 to prevent the transverse block 53 from deviating. This, in turn, drives the transverse flattening roller 58 to roll back and forth along the vertical conveying direction to flatten the metal strip laterally and eliminate warping and wrinkles of the metal strip in the vertical conveying direction. Forward flattening stage: The metal strip that has completed lateral flattening continues to be conveyed by conveyor 4. When the front end of the metal strip reaches directly below the forward flattening component 6, the forward flattening component 6 is activated, and every two oppositely positioned lifting hydraulic cylinders 63 move synchronously under the drive of the same hydraulic control system. If a parallel oil circuit with a synchronization valve is used, the hydraulic oil is evenly distributed to the two hydraulic cylinders through the synchronization valve to ensure consistent oil intake; if servo control is used, the position sensor monitors the displacement of the piston rods of the two hydraulic cylinders in real time, and the servo motor adjusts the output flow of the hydraulic pump to compensate for the displacement difference. The piston rods extend downwards synchronously with the same extension length. The extended piston rods drive the corresponding mounting supports 64 to descend vertically synchronously. During this process, the guide holes 67 on the mounting supports 64 slide smoothly along the support shaft 66 at the upper end of the support plate 61, further limiting the offset of the mounting supports 64. The forward flattening roller 65, which is rotatably installed between the two opposing mounting supports 64, moves downwards accordingly. Because the two mounting supports 64 rise and fall synchronously, the forward flattening roller 65 remains horizontal until it contacts the surface of the metal strip and applies a preset flattening force. Subsequently, the forward flattening roller 65 rolls synchronously with the conveying direction of the metal strip to flatten the metal strip in the forward direction, eliminate the stress deformation of the metal strip in the conveying direction, and achieve bidirectional full flattening. Cutting stage: After being flattened in both directions, the metal strip continues to be conveyed by the conveyor 4 to the cutting platform 7. When the conveying length of the metal strip on the cutting platform 7 reaches the preset cutting size, the conveyor 4 stops running, and the cutting mechanism 8 on the cutting platform 7 is activated, such as a hydraulic cutter, to cut the flattened metal strip. After the cutting is completed, the conveyor 4 resumes operation and continues to convey subsequent flattened metal strips. The cut metal strip products can be collected from the discharge end of the cutting platform 7, thus completing the flattening and cutting process of a single metal coil. By repeating the above process, continuous flattening and cutting production of metal coils can be realized. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
