Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal plate manufacturing technology, and in particular to a thin plate chain turning machine. Background Technology
[0002] In the field of sheet metal manufacturing, especially in the processing of large thin sheets such as refrigerated containers, it is often necessary to flip wide and long thin sheets (such as outer top panels, outer side panels, and inner side panels) 180 degrees. Because thin sheets have low rigidity and are easily deformed, the flipping process must balance efficiency and safety. Currently, the industry commonly uses cage-type flipping machines, but they have the following significant drawbacks:
[0003] The structure is bulky and inefficient: the cage-type tilting machine is large in size and requires installation in a pit, which makes the equipment fixed and cannot be moved. Moreover, the tilting speed is slow, which seriously affects the production cycle.
[0004] Insufficient compatibility and flexibility: The equipment has poor adaptability to thin plate dimensions (length, width, thickness), requiring adjustments to the equipment structure or replacement of parts according to different specifications, increasing operating costs.
[0005] High initial investment: The cost of a 12-meter-long cage-type tilting machine that can be adapted to a 2.5-meter-wide thin plate is as high as 400,000 yuan. In addition, the cost of pit construction (about 200,000 yuan) is huge.
[0006] Operational stability issues: The lack of effective chain anti-sagging and positioning devices during the flipping process can easily lead to chain derailment or thin plate slippage, requiring frequent shutdowns for maintenance and increasing safety hazards.
[0007] In existing technologies, the typical process for thin plate flipping is as follows: the thin plate is fed into a squirrel-cage flipping machine via a belt conveyor, and the flipping is driven by a power system in the pit. After completion, it is picked up by another belt conveyor. This process not only relies on a complex pit structure, but also results in a rigid production line layout due to the fixed equipment, making it difficult to adapt to the needs of modern flexible production.
[0008] The purpose of this invention is to solve the above problems. By using a chain-type flipping structure, modular design and precise limiting device, it achieves high efficiency, stability and low cost of thin plate flipping, while breaking through the dependence of traditional equipment on pits and improving production flexibility.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0042] like Figures 1 to 6 As shown, the embodiment of this utility model includes: The thin plate chain turning machine of this embodiment is mainly composed of the following components:
[0043] Flip frame 1000: includes upper frame 1001, lower frame 1002 and fixed frame 1100. A gap is left between the upper frame and the lower frame to accommodate the thin plate.
[0044] Upper transmission assembly: installed at the bottom of the upper frame, including upper active support wheel 1003, multiple upper driven support wheels 1004 and upper transmission belt 1005; upper tension wheel 1011 is used to adjust belt tension.
[0045] Lower transmission assembly: mounted on the top of the lower frame, including a lower active support wheel 1006, multiple lower driven support wheels 1007, a lower transmission belt 1008, and a lower transmission shaft 1009 connected in series with all the lower active support wheels; the lower tension wheel 1012 is used to maintain belt tension.
[0046] Workpiece clamping assembly: includes a lower clamping plate 1013, a clamping cylinder 1014 and an upper clamping plate 1015. The upper clamping plate is driven to press down by the cylinder and cooperates with the lower clamping plate to fix the thin plate.
[0047] Support frame 2000: Composed of support frame 2001, support foot 2002 and support plate 2003, used to support the flip frame 1000 and chain flip structure 3000.
[0048] The belt-driven power transmission structure 2100 includes a support base 2101, a first bearing housing 2102, a power shaft 2103, a driven sprocket 2104, a second transmission gear 2105, a first motor 2106, a drive sprocket 2107, and a first chain 2108. The second transmission gear 2105 meshes with the first transmission gear 1010 at the end of the lower transmission shaft 1009, and drives the lower transmission belt 1008 to rotate in both directions via the first motor.
[0049] Chain-type flipping structure 3000: flipping frame 3100: the top is provided with a first power platform 3101 and a second power platform 3102, and the bottom is provided with a first drag chain groove and a second drag chain groove.
[0050] Power Component A: Installed on the first power platform 3101, including a first reversing motor 3206, a reversing shaft A3202, a first reversing sprocket 3203, a second reversing sprocket 3204, a first driven sprocket a3205, a first driving sprocket a3207, and a first reversing chain 3401.
[0051] Power Component B: Installed on the second power platform 3102, including a second reversing motor 3306, a reversing shaft B3302, a third reversing sprocket 3303, a fourth reversing sprocket 3304, a second driven sprocket a3305, a second driving sprocket a3307, and a second reversing chain 3402.
[0052] Tensioning sprocket assembly: The first to eighth tensioning sprockets 3501-3508 are arranged in a U-shape to ensure stable chain running trajectory.
[0053] like Figure 7 As shown, the working steps of this technical solution are as follows:
[0054] Thin plate feeding: The first motor 2106 starts, driving the drive sprocket 2107 to drive the driven sprocket 2104 through the first chain 2108, so that the second transmission gear 2105 on the power shaft 2103 meshes with the first transmission gear 1010 on the lower transmission shaft 1009, and the lower transmission belt 1008 rotates forward, conveying the thin plate into the flipping frame 1000; the clamping cylinder 1014 is activated, the upper clamping plate 1015 is pressed down, and cooperates with the lower clamping plate 1013 to fix the thin plate.
[0055] Lifting of the flip frame: The first flip motor 3206 drives the flip shaft A3202 to rotate counterclockwise, and the second flip motor 3306 drives the flip shaft B3302 to rotate clockwise. The first flip chain 3401 and the second flip chain 3402 move upward synchronously, driving the flip frame 1000 to be lifted vertically.
[0056] Single-sided flipping: When the flipping frame rises to half its height, the second flipping motor 3306 stops, the first flipping motor 3206 continues to rotate counterclockwise, and the flipping frame 1000 tilts clockwise with the bottom edge as the fulcrum until it is in a vertical state.
[0057] Complete the flipping: the first flipping motor 3206 stops, the second flipping motor 3306 starts and rotates counterclockwise, and the flipping frame 1000 continues to rotate clockwise 180° before returning to a horizontal state.
[0058] Reset of the flip frame: The first flip motor 3206 rotates clockwise, the second flip motor 3306 rotates counterclockwise, the chain moves down synchronously, and the flip frame 1000 descends to the initial position.
[0059] When the clamping cylinder 1014 is released, the first motor 2106 reverses, and the lower transmission belt 1008 sends out the flipped thin plate.
[0060] The working principle of this technical solution is as follows:
[0061] Transmission and power distribution: The belt power transmission structure 2100 transmits the power of the first motor 2106 to the lower transmission shaft 1009 through gear meshing and chain transmission, thereby driving the lower transmission belt 1008 to realize the conveying of thin plates.
[0062] In the chain-type flipping structure 3000, two sets of motors 3206 and 3306 drive the flipping shafts A and B respectively. Through the cooperation of chains and sprockets, the lifting, tilting and flipping actions of the flipping frame are controlled.
[0063] Chain trajectory control: The tension sprocket assembly 3501-3508 forms a U-shaped layout to ensure that the flip chains 3401 and 3402 always fit the sprockets during movement, preventing chain slippage or loosening.
[0064] The chain groove (located at the bottom of the tilting frame) further restricts the lateral displacement of the chain, improving operational stability.
[0065] Clamping and synchronization: The clamping assembly fixes the thin plate during the flipping process to prevent displacement; the dual motors alternately drive to achieve the continuity and precision of the flipping action.
[0066] The advantages of this technical solution are:
[0067] High-efficiency flipping: Dual motors combined with chain drive enable rapid lifting and multi-angle flipping of the frame, greatly improving work efficiency.
[0068] Stable operation: The tensioning pulleys 1011 and 1012 and the drag chain groove design effectively prevent belt and chain collapse; the "U" layout of the tensioning sprocket set ensures accurate chain trajectory.
[0069] Modular design: Power components A and B are independently installed on power platforms 3101 and 3102, which facilitates maintenance and component replacement.
[0070] High safety: The clamping assembly firmly secures the thin plate during the flipping process, avoiding the risk of slippage; the alternating control logic of the motor prevents overload.
[0071] Pitless design: No pit installation is required, saving construction costs and supporting flexible equipment movement and rapid production line adjustment.
[0072] Chain life optimization: Closed-loop guide path and drag chain groove reduce chain wear and extend the service life of key components.
[0073] Rapid changeover capability: Standardized interface design enables rapid adaptation to thin board dimensions, improving production flexibility.
[0074] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
