Description

Technical Field

[0001] This utility model relates to the field of cold bending forming technology, specifically, to a cold bending forming machine unit for the production of light steel keel ceilings. Background Technology

[0002] Cold bending is a metal processing technology that uses multiple sets of sequentially arranged rollers to continuously bend coils or strips at room temperature, gradually shaping them into profiles with specific cross-sections. This process has the advantages of high efficiency, material saving, and the ability to produce products with complex cross-sections, and is widely used in the manufacturing fields of construction, automobiles, and furniture.

[0003] In the existing technology, operators often use corresponding cold bending forming units to perform cold bending operations on steel during the production of light steel keel ceilings. However, in actual use, although the existing cold bending forming units have basic cold bending functions, they are prone to skewed or offset feeding of materials due to the lack of limiting the feeding angle. Such skewed materials cannot be correctly formed in each roller, resulting in fatal defects such as twisting, warping, asymmetrical cross-sectional shape, and out-of-tolerance dimensions in the final product, and even scrap. Therefore, it is necessary to improve them. Utility Model Content

[0006] For example, at least one embodiment of this utility model provides a cold bending forming unit for producing light steel keel ceilings, wherein a No. 1 connecting frame is fixedly connected to the inner surface of the base plate, a fine thread rod is movably sleeved at the bottom of the No. 1 connecting frame, and the top of the fine thread rod penetrates through the No. 1 connecting frame and extends into the inner cavity of the No. 1 connecting frame and is threadedly sleeved with a roller pressing frame.

[0007] For example, at least one embodiment of this utility model provides a cold bending forming unit for producing light steel keel ceilings, wherein support rods are fixedly connected to the four corners of the bottom of the base plate, and the number of support rods is four, and the four support rods are all the same size.

[0008] For example, at least one embodiment of this utility model provides a cold bending forming unit for producing light steel keel ceilings, wherein a second connecting frame is fixedly installed on the inner surface of the base plate, a limiting rod is fixedly sleeved inside the second connecting frame, and the outer surface of the limiting rod is movably sleeved with the inner surface of the roller pressing frame.

[0009] For example, at least one embodiment of this utility model provides a cold bending forming unit for producing light steel keel ceilings, wherein a first pressure roller is movably sleeved inside the roller pressing frame, a lifting frame is movably connected to the top of the inner cavity of the roller pressing frame, and a second pressure roller is movably sleeved inside the lifting frame.

[0010] For example, at least one embodiment of this utility model provides a cold bending forming unit for producing light steel keel ceilings, wherein a support base is fixedly connected to the top of the roller press frame, a drive motor is fixedly installed inside the support base, and a second rotating shaft is fixedly sleeved at the other end of the output shaft of the drive motor.

[0011] For example, at least one embodiment of this utility model provides a cold bending forming unit for producing light steel keel ceilings, wherein an eccentric rod is fixedly sleeved on the outer surface of the second rotating shaft, a sleeve rod is movably connected to the outer surface of the eccentric rod, and a rectangular rod is fixedly connected to the bottom of the sleeve rod.

[0012] For example, at least one embodiment of this utility model provides a cold bending forming unit for producing light steel keel ceilings, wherein the bottom of the rectangular rod passes through the roller pressing frame and extends into the inner cavity of the roller pressing frame and is movably sleeved with the inner surface of the roller pressing frame, and the bottom end of the rectangular rod is fixedly connected to the top of the lifting frame.

[0013] For example, at least one embodiment of this utility model provides a cold bending forming unit for producing light steel keel ceilings, wherein vertical rods are fixedly connected to both the front and rear sides of the top of the lifting frame, and the top of the vertical rods penetrates through the roller pressing frame and extends to the outside of the roller pressing frame and is fixedly connected to the bottom of the sleeve rod.

[0014] For example, at least one embodiment of this utility model provides a cold bending forming unit for producing light steel keel ceilings, wherein a laser sensor is fixedly sleeved inside the top of the roller pressing frame, and a controller is fixedly connected to the top of the front side of the roller pressing frame.

[0015] The beneficial effects of this utility model are as follows: 1. This utility model, by setting up a first rotating shaft, a rotating rod, a hollow rod, a C-shaped rod, and guide plates, when the servo motor starts running, will cause the first rotating shaft to drive the rotating rod to rotate. At this time, the rotating rod will squeeze and push the hollow rod, so that the two hollow rods will drive the C-shaped rod to move horizontally towards each other under the limiting action of the fixed frame and the mounting frame. This allows the two guide plates to move closer to each other along the inner cavity of the mounting frame. Then, the inclined surface on the guide plate will guide and straighten the steel passing through the mounting frame, avoiding the product from twisting, warping, and other phenomena, and ensuring product quality.

[0016] 2. This utility model, by setting up a sleeve rod, a rectangular rod, a vertical rod, a laser sensor, and a controller, starts the drive motor, which drives the second rotating shaft to rotate synchronously with the eccentric rod. At this time, the eccentric rod will squeeze the sleeve rod, causing the sleeve rod to drive the rectangular rod and the vertical rod to be lifted vertically upward under the limiting action of the roller pressing frame. At this time, the lifting frame will drive the second pressure roller to rise along the inner cavity of the roller pressing frame, thereby realizing the function of adjusting the distance between the second pressure roller and the first pressure roller. This allows the device to adapt to plates of different thicknesses. When the laser sensor detects that the lifting frame has reached the predetermined height, it sends a signal to the controller, which then controls the drive motor to stop running, achieving precise height control. This ensures that each second pressure roller can also roll the plate passing under it after being lifted, avoiding the situation of being suspended. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0020] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0021] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0024] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] like Figures 1-5 As shown, it illustrates a cold bending forming unit for producing light steel keel ceilings according to an embodiment of the present invention, including a base plate 1, a fixed frame 2 fixedly connected to the top of the base plate 1, an mounting frame 3 fixedly connected to the top of the fixed frame 2, a servo motor 4 fixedly connected to the top of the inner cavity of the fixed frame 2, a first rotating shaft 5 fixedly sleeved at the other end of the output shaft of the servo motor 4, a rotating rod 6 fixedly sleeved on the outer surface of the first rotating shaft 5, hollow rods 7 movably connected to both the left and right sides of the outer surface of the rotating rod 6, a C-shaped rod 8 fixedly connected to the outer side of the hollow rod 7, and the other end of the C-shaped rod 8 sequentially passing through the fixed frame 2 and the mounting frame 3 and extending into the inner cavity of the mounting frame 3 and fixedly connected to a guide plate 9, the outer surface of the guide plate 9 being movably connected to the inner surface of the mounting frame 3.

[0026] The smooth outer surface of the C-shaped rod 8 allows it to slide more smoothly within the cavities of the fixing frame 2 and the mounting frame 3, effectively reducing friction between it and the fixing frame 2 and the mounting frame 3, thereby improving the service life of the C-shaped rod 8.

[0027] In some examples, a first connecting frame 11 is fixedly connected to the inner surface of the base plate 1. A fine thread rod 12 is movably sleeved at the bottom of the first connecting frame 11. The top of the fine thread rod 12 passes through the first connecting frame 11 and extends into the inner cavity of the first connecting frame 11, and is threadedly sleeved with a roller pressing frame 13.

[0028] The fine-thread rod 12 has a self-locking function, so that rotating the fine-thread rod 12 will prevent the roller press frame 13 from falling back unexpectedly after it is raised.

[0029] In some examples, support rods 10 are fixedly connected to the four corners of the bottom of the base plate 1. There are four support rods 10, and the four support rods 10 are all the same size.

[0030] The design of four support rods 10 together supports the overall weight of the device, effectively improving the stability and load-bearing capacity of the support structure.

[0031] In some examples, a second connecting frame 14 is fixedly installed on the inner surface of the base plate 1. A limiting rod 15 is fixedly sleeved inside the second connecting frame 14, and the outer surface of the limiting rod 15 is movably sleeved with the inner surface of the roller pressing frame 13.

[0032] Due to the limiting effect of the limiting rod 15, the roller press frame 13 can only move vertically up and down along the inner surface of the second connecting frame 14.

[0033] In some examples, a first pressure roller 16 is movably sleeved inside the roller press frame 13, a lifting frame 17 is movably connected to the top of the inner cavity of the roller press frame 13, and a second pressure roller 18 is movably sleeved inside the lifting frame 17.

[0034] The steel will pass through the roll gap between multiple sets of first pressure rollers 16 and second pressure rollers 18 in sequence. By adjusting the height of different sets of second pressure rollers 18, the steel will be gradually bent.

[0035] In some examples, a support base 19 is fixedly connected to the top of the roller press 13, and a drive motor 20 is fixedly installed inside the support base 19. The other end of the output shaft of the drive motor 20 is fixedly sleeved with a second rotating shaft 21.

[0036] The drive motor 20 supports forward and reverse rotation control and has a self-locking function. By controlling the number of revolutions or the time of forward and reverse rotation through the program, high-precision position control can be achieved. At the same time, the self-locking function ensures that the motor will not drift due to external force after it stops, thus ensuring the accuracy of control.

[0037] In some examples, an eccentric rod 22 is fixedly sleeved on the outer surface of the second rotating shaft 21, a sleeve rod 23 is movably connected to the outer surface of the eccentric rod 22, and a rectangular rod 24 is fixedly connected to the bottom of the sleeve rod 23.

[0038] When the second rotating shaft 21 drives the eccentric rod 22 to rotate synchronously, the eccentric rod 22 will press against the inner wall of the sleeve rod 23, thereby causing the sleeve rod 23 to rise upward.

[0039] In some examples, the bottom of the rectangular rod 24 passes through the roller press frame 13 and extends into the inner cavity of the roller press frame 13 and is movably sleeved with the inner surface of the roller press frame 13, and the bottom end of the rectangular rod 24 is fixedly connected to the top of the lifting frame 17.

[0040] The outer surface of the rectangular rod 24 is smooth, which makes the sliding of the rectangular rod 24 on the inner surface of the roller frame 13 smoother.

[0041] In some examples, vertical rods 25 are fixedly connected to the front and rear sides of the top of the lifting frame 17. The top of the vertical rods 25 passes through the roller pressing frame 13 and extends to the outside of the roller pressing frame 13 and is fixedly connected to the bottom of the sleeve rod 23.

[0042] Due to the limiting effect of the vertical rod 25, the lifting frame 17 driven by the sleeve rod 23 through the rectangular rod 24 will not shake or deviate during the lifting process, thus improving the operational stability.

[0043] In some examples, a laser sensor 26 is fixedly fitted inside the top of the roller press 13, and a controller 27 is fixedly connected to the top of the front side of the roller press 13.

[0044] The laser sensor 26 will detect the height of the lifting frame 17 in real time. When the predetermined height is reached, the laser sensor 26 sends a signal to the controller 27, which then controls the drive motor 20 to stop running, thereby achieving precise height control.

[0045] Working principle and usage process of this utility model: Before cold bending, the operator needs to pre-rotate multiple fine-thread rods 12 to adjust the height of multiple roller frames 13, so as to ensure that the steel can achieve the required curvature and bending cross section after passing through. The plate material conveyed from the previous process will pass through the inside of the mounting frame 3 in sequence between multiple sets of first pressure rollers 16 and second pressure rollers 18, thereby realizing the cold bending process. When loading, the servo motor 4 needs to be started and the first rotating shaft 5 is driven to rotate the rotating rod 6. At this time, the rotating rod 6 will squeeze and push the hollow rod 7, so that the two hollow rods 7 will drive the C-shaped rod 8 to move horizontally towards each other under the limiting action of the fixed frame 2 and the mounting frame 3, so that the two guide plates 9 will move closer to each other along the inner cavity of the mounting frame 3. Then, the inclined surface on the guide plate 9 will guide and correct the steel material passing through the mounting frame 3, avoiding the product from twisting, warping, etc., and ensuring product quality.

[0046] If the sheet material is thick and it is difficult to establish an initial distance between the first pressure roller 16 and the second pressure roller 18, the drive motor 20 is started, driving the second rotating shaft 21 to drive the eccentric rod 22 to rotate synchronously. At this time, the eccentric rod 22 will squeeze the sleeve rod 23, causing the sleeve rod 23 to drive the rectangular rod 24 and the vertical rod 25 to rise vertically upward under the limiting action of the roller pressing frame 13. At this time, the lifting frame 17 will drive the second pressure roller 18 to rise along the inner cavity of the roller pressing frame 13, thereby realizing the function of adjusting the distance between the second pressure roller 18 and the first pressure roller 16, so that the device can adapt to sheet materials of different thicknesses. When the laser sensor 26 detects that the lifting frame 17 has reached the predetermined position, it sends a signal to the controller 27, and the controller 27 controls the drive motor 20 to stop running, realizing precise height control and ensuring that each second pressure roller 18 can also roll the sheet material passing under it after being lifted, avoiding the situation of suspension.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
