Description

Technical Field

[0001] This application relates to the field of sheet metal processing technology, and more specifically, to a sheet metal flattening device for sheet metal processing. Background Technology

[0002] Sheet metal parts are metal parts made through sheet metal processing technology. They are usually made from thin metal sheets (such as steel, aluminum, copper, etc.) through processes such as cutting, bending, stamping, and welding. Sheet metal parts are characterized by light weight, high strength, low cost, and high production efficiency, and are an indispensable component of many products.

[0003] Current flattening devices, such as CN219052486U (announcement number: CN219052486U), "A flattening device for sheet metal processing," use a pull plate to move the work plate. The work plate engages with a limiting groove under the action of a slider, and simultaneously engages with a locking screw to fix the position of the work plate, ensuring the processing quality of the device. At the same time, a pressure-resistant plate is placed on top of the work plate. The locking block at the bottom of the pressure-resistant plate matches the rectangular groove, and the vertical rod engages with the round hole and works under the action of a return spring, thereby improving the buffering performance of the pressure-resistant plate and ensuring the stability of stamping. It has high practicality.

[0004] However, while the device can guarantee the flattening effect, in actual use, when flattening sheet metal parts with a fixed-size stamping plate, the sheet metal parts are prone to uneven stress distribution, leading to local deformation. Especially in the edge area of ​​the stamping plate, the pressure concentration will squeeze the surface of the sheet metal parts, forming indentations or scratches, affecting the appearance quality and subsequent processing performance of the sheet metal parts. Generally, indentations can only be avoided when the stamping plate can completely cover the sheet metal. Therefore, it needs to be improved and optimized. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this application provides a sheet metal flattening device for sheet metal processing, which has the advantages of good flattening effect and prevention of indentation.

[0006] To achieve the above objectives, this application provides the following technical solution: a sheet metal flattening device for sheet metal processing, comprising a flattening chamber, a flattening mechanism provided inside the flattening chamber, the flattening mechanism including limiting rods on the front and rear sides of the flattening chamber, a pressure plate movably installed inside the flattening chamber, protrusions fixedly installed at the four corners of the top of the pressure plate, the four sets of protrusions sleeved on the outer wall of the limiting rods, a pressure roller rotatably installed at the bottom of the pressure plate, and a hydraulic cylinder fixedly installed at the top of the flattening chamber, the telescopic end of the hydraulic cylinder penetrating into the interior of the flattening chamber and fixedly connected to the pressure plate;

[0007] The flattening chamber is equipped with a feeding mechanism, which includes a conveying trough at the bottom of the flattening chamber. A conveying roller is rotatably installed inside the conveying trough, and the conveying roller and the pressure roller are positioned correspondingly. A motor is fixedly installed on the outer wall of the conveying trough, and the output shaft of the motor passes through the interior of the conveying trough and is fixedly connected to the conveying roller.

[0008] As a preferred technical solution of this application, the feeding mechanism is provided with an anti-deviation mechanism. The anti-deviation mechanism includes movable grooves at the front and rear ends of the conveying roller, and anti-deviation rings are movably installed inside the two sets of movable grooves.

[0009] As a preferred technical solution of this application, the two sets of movable slots are rotatably installed with lead screws, and both sets of lead screws are threadedly connected to anti-deviation rings.

[0010] As a preferred technical solution of this application, a dual-axis motor is fixedly installed inside the conveying roller. The output shafts at both ends of the dual-axis motor are respectively fixedly connected to two sets of lead screws. The pitch of the two sets of lead screws is the same and the thread opening direction is opposite.

[0011] As a preferred technical solution of this application, a discharge port is provided on the left side of the flattening chamber, and a cleaning mechanism is provided on the right side of the flattening chamber.

[0012] As a preferred technical solution of this application, the cleaning mechanism includes a fixed frame fixedly installed on the right side wall of the flattening chamber, a first cleaning roller rotatably installed inside the fixed frame, guide grooves are provided at both the front and rear ends of the right side wall of the flattening chamber, a movable frame is movably installed inside the guide grooves, and a second cleaning roller is rotatably installed inside the movable frame.

[0013] As a preferred technical solution of this application, a guide rod is fixedly installed inside the guide groove, the guide rod is movably sleeved with the movable frame, and the guide rod and the guide groove are elastically connected by a spring.

[0014] Compared with the prior art, the beneficial effects of this application are as follows:

[0015] 1. This application uses the operation of hydraulic cylinders to flatten the sheet metal using pressure rollers and conveyor rollers. Simultaneously, with the operation of the motor, the conveyor rollers rotate during the flattening process, transporting the sheet metal to the discharge port. More importantly, this device also incorporates an anti-deviation mechanism, which restricts the movement path of the sheet metal during transportation using two sets of anti-deviation rings. This allows the device to achieve progressive, non-destructive flattening operations, while automatically loading and unloading the sheet metal. Furthermore, it prevents deviation or misalignment during transportation, effectively improving flattening efficiency and the quality of the flattened sheet metal.

[0016] 2. This application utilizes the elastic potential energy of a spring to ensure that before the sheet material enters the flattening chamber through the cleaning mechanism, the second cleaning roller and the first cleaning roller abut against each other, sweeping away any remaining impurities and debris on both sides of the sheet material. Compared to traditional devices, this device uses the elastic potential energy of a spring to compress the second cleaning roller, while the sheet material presses against the first cleaning roller due to its own weight, ensuring a tight fit between the second and first cleaning rollers and the sheet material, preventing the residue of impurities and foreign objects, and improving the flattening effect.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0026] like Figures 1 to 6 As shown, the sheet metal flattening device for sheet metal processing provided in this application includes a flattening chamber 1, a flattening mechanism 2 is provided inside the flattening chamber 1, the flattening mechanism 2 includes limiting rods 22 opened on the front and rear sides of the flattening chamber 1, a pressure plate 24 is movably installed inside the flattening chamber 1, and protrusions 23 are fixedly installed at the four corners of the top of the pressure plate 24. The four sets of protrusions 23 are sleeved on the outer wall of the limiting rods 22. A pressure roller 25 is rotatably installed at the bottom of the pressure plate 24. A hydraulic cylinder 21 is fixedly installed at the top of the flattening chamber 1. The telescopic end of the hydraulic cylinder 21 penetrates into the interior of the flattening chamber 1 and is fixedly connected to the pressure plate 24.

[0027] The flattening chamber 1 is equipped with a feeding mechanism 3. The feeding mechanism 3 includes a conveying trough 31 at the bottom of the flattening chamber 1. A conveying roller 32 is rotatably installed inside the conveying trough 31. The conveying roller 32 and the pressure roller 25 are positioned correspondingly. A motor 33 is fixedly installed on the outer wall of the conveying trough 31. The output shaft of the motor 33 passes through the interior of the conveying trough 31 and is fixedly connected to the conveying roller 32.

[0028] When it is necessary to flatten the metal sheet, the operator starts the hydraulic cylinder 21. The operation of the hydraulic cylinder 21 will drive the pressure plate 24 to move downward. The protrusions 23 at both ends of the pressure plate 24 will move along the limit rod 22. The pressure roller 25 and the conveying roller 32 will clamp and flatten the sheet. Then the operator starts the motor 33. The operation of the motor 33 will drive the conveying roller 32 to rotate. The rotation of the conveying roller 32 will convey the sheet inward. During the conveying, the cooperation of the pressure roller 25 and the conveying roller 32 will flatten the sheet.

[0029] The hydraulic cylinder 21 operates to flatten the sheet metal by pressing the pressure roller 25 and conveying roller 32. Simultaneously, the motor 33 operates to rotate the conveying roller 32 during the flattening process, transporting the sheet metal out of the flattening chamber 1. Through the cooperation of multiple sets of pressure rollers 25 and conveying rollers 32, the sheet metal is flattened step by step, enabling the device to achieve progressive and non-destructive flattening operations. This avoids indentations caused by concentrated pressure, and allows for automatic feeding and unloading of the sheet metal. Furthermore, it prevents misalignment during transportation, effectively improving flattening efficiency and the quality of the flattened sheet metal.

[0030] The feeding mechanism 3 has an anti-deviation mechanism 4 inside. The anti-deviation mechanism 4 includes movable grooves 41 at the front and rear ends of the conveying roller 32. Anti-deviation rings 42 are movably installed inside the two sets of movable grooves 41.

[0031] By setting two sets of anti-deviation rings 42, the plate is limited between the two sets of anti-deviation rings 42, thereby restricting the displacement path of the plate and preventing the plate from shifting or misaligning when flattening. Since the anti-deviation rings 42 can move within the movable groove 41, the distance between the two sets of anti-deviation rings 42 can be adjusted, thus making it suitable for limiting plates of different sizes.

[0032] The two sets of movable grooves 41 are equipped with lead screws 43, which are threadedly connected to anti-deviation rings 42. The rotation of the lead screws 43 drives the anti-deviation rings 42 to move along the movable grooves 41.

[0033] The conveyor roller 32 is internally fixedly equipped with a dual-axis motor 44. The output shafts at both ends of the dual-axis motor 44 are fixedly connected to two sets of lead screws 43, respectively. The two sets of lead screws 43 have the same pitch and opposite thread opening directions.

[0034] Since the threads of the two sets of lead screws 43 are opened in opposite directions, when the dual-shaft motor 44 is operating, the two sets of anti-deviation rings 42 move synchronously closer to each other or further away from each other to adjust the distance between the two sets of anti-deviation rings 42.

[0035] The flattening chamber 1 has a discharge port 5 on its left side and a cleaning mechanism 6 on its right side.

[0036] When it is necessary to flatten metal sheets, the staff first inserts the sheet into the flattening chamber 1 through the cleaning mechanism 6, flattens it inside the flattening chamber 1, and finally discharges the sheet through the discharge port 5 to complete the flattening operation.

[0037] The cleaning mechanism 6 includes a fixed frame 61 fixedly installed on the right side wall of the flattening chamber 1. A first cleaning roller 62 is rotatably installed inside the fixed frame 61. Guide grooves 63 are provided at both the front and rear ends of the right side wall of the flattening chamber 1. A movable frame 66 is movably installed inside the guide grooves 63. A second cleaning roller 67 is rotatably installed inside the movable frame 66.

[0038] Since the fixed frame 61 for mounting the first cleaning roller 62 is fixedly mounted on the side wall of the flattening chamber 1, and the movable frame 66 for mounting the second cleaning roller 67 can move up and down along the guide groove 63 on the side wall of the flattening chamber 1, the distance between the first cleaning roller 62 and the second cleaning roller 67 is adjustable. When the board enters between the first cleaning roller 62 and the second cleaning roller 67, the second cleaning roller 67 will fall onto the board under the action of gravity, causing the second cleaning roller 67, the first cleaning roller 62, and the upper and lower surfaces of the board to come into contact with each other, thereby cleaning the upper and lower surfaces of the board. This ensures that the two surfaces of the board that need to be flattened are cleaned before the board enters the flattening chamber 1.

[0039] The guide groove 63 is fixedly installed with a guide rod 64, which is movably connected to the movable frame 66. The guide rod 64 and the guide groove 63 are elastically connected by a spring 65.

[0040] Before flattening the board, the board is cleaned by the cleaning mechanism 6 and then inserted into the flattening chamber 1. Furthermore, due to the thickness of the board, the upper surface of the board will come into contact with the second cleaning roller 67, which will push the second cleaning roller 67 upward. At this time, the moving frame 66 will move upward along the guide rod 64, and the spring 65 will be compressed. The moving frame 66 will exert a downward force on the second cleaning roller 67 through the elastic potential energy of the spring 65, so that the second cleaning roller 67 and the first cleaning roller 62 squeeze the upper and lower ends of the board. As the board is continuously pushed in, the second cleaning roller 67 and the first cleaning roller 62 will clean the two sides of the board that need to be flattened, so as to avoid damage to the board.

[0041] Using the elastic potential energy of spring 65, before the board enters the flattening chamber 1 through the cleaning mechanism 6, the second cleaning roller 67 and the first cleaning roller 62 bring the board into contact with each other and sweep away the impurities and debris remaining on both sides of the board. Compared with the traditional device, this device uses the elastic potential energy of spring 65 to press the second cleaning roller 67 downward, while the board presses on the first cleaning roller 62 by its own weight, so that the second cleaning roller 67 and the first cleaning roller 62 are in close contact with the board, avoiding the residue of impurities and foreign objects and improving the flattening effect.

[0042] The working principle and usage process of this application:

[0043] When flattening metal sheets, the operator first inserts the sheet into the flattening chamber 1 using the cleaning mechanism 6. Then, the operator activates the hydraulic cylinder 21, which moves the pressure plate 24 downwards. Further, the protrusions 23 at both ends of the pressure plate 24 move along the limit rod 22, and the pressure roller 25 and conveyor roller 32 clamp and flatten the sheet. Next, the operator activates the motor 33, which drives the conveyor roller 32 to rotate. The rotation of the conveyor roller 32 then transports the sheet inwards, and the cooperation of the pressure roller 25 and conveyor roller 32 during transport flattens the sheet. When conveying the sheet material, the operator can start the dual-axis motor 44. The operation of the dual-axis motor 44 will drive the two sets of lead screws 43 to rotate synchronously. The rotation of the lead screws 43 will cause the anti-deviation rings 42, which are threaded together with them, to move inside the movable groove 41. Since the threads of the two sets of lead screws 43 are opened in opposite directions, the distance between the two sets of anti-deviation rings 42 is shortened. As the distance between the two sets of anti-deviation rings 42 is shortened, the movement path of the sheet material is restricted by the anti-deviation rings 42 to prevent the sheet material from deviating. Finally, the sheet material will be discharged through the discharge port 5, completing the flattening operation.

[0044] Before flattening the board, the board passes through the cleaning mechanism 6 and then enters the flattening chamber 1. Furthermore, due to the thickness of the board as it enters, the board comes into contact with the second cleaning roller 67, which pushes the second cleaning roller 67 upward. At this time, the moving frame 66 moves upward along the guide rod 64, and the spring 65 is compressed. The moving frame 66 uses the elastic potential energy of the spring 65 to make the second cleaning roller 67 and the first cleaning roller 62 squeeze the upper and lower ends of the board. As the board is continuously pushed in, the second cleaning roller 67 and the first cleaning roller 62 clean the two sides of the board that need to be flattened, thus preventing damage to the board.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
