[0026] Reference Figure 1-Figure 5 A medium-thickness plate straightening machine includes a frame, a pre-straightening station and a straightening station are provided on the frame, the pre-straightening station includes an upper pressing plate 6 and a lower pressing plate 4, the lower pressing plate 4 is slidably connected to the slide rail 3 of the frame, the upper pressing plate 6 is connected to the output end of the lifting motor 7, and the lifting motor 7 is fixedly connected to the translation plate; a threaded through hole is opened in the horizontal direction of the translation plate, and a translation rod is threadedly connected in the threaded through hole, and the translation rod is driven by the horizontal motor, and the side of the lower pressing plate 4 away from the straightening station is connected to the first end of the tension spring 12, and the second end of the tension spring 12 is connected to the feed port of the frame.
[0027] During use, the medium and thick plate (thickness of 20mm-50mm) to be pressed is placed in the pre-straightening station from the feed port. The width of the feed port is greater than the width of the medium and thick plate to ensure smooth feeding. When the end of the medium and thick plate reaches the edge position of the upper pressure plate 6 and the lower pressure plate 4, the inward pushing action is stopped, and the lifting motor 7 is started to drive the lower pressure plate 4 downward to perform a preliminary flattening operation on the medium and thick plate. After the pressing is completed, the horizontal motor is started to drive the translation plate to move toward the straightening station. During the movement, the lower pressure plate 4 always maintains a pressing state on the medium and thick plate. After reaching the end of the straightening station, the upper pressure plate 6 is separated from the medium and thick plate, and the lower pressure plate 4 is driven to reset by the tension spring 12. The horizontal motor drives the translation plate to reset, and then the pressing action is repeated. No auxiliary pushing is required during the pressing process.
[0028] In other preferred embodiments, the straightening station is provided with an outer frame 5, with an inlet opening defined on a first side panel and an outlet opening defined on a second side panel. The first and second side panels are connected by a top panel, and a horizontal motor is fixedly connected to the first side panel. Two sets of horizontal columns are provided between the first and second side panels, and the translation plate is provided with sliding holes, into which the horizontal columns are adapted to connect. The provision of the horizontal columns ensures a more stable movement of the translation plate, ensuring smooth horizontal movement.
[0029] The first side plate is further fixedly connected with a positioning column 13, and the end of the positioning column 13 is made of elastic material, which can reduce the impact force when the lower pressure plate rebounds.
[0030] Two groups of through holes are vertically arranged on the translation plate, and a limiting column 8 is slidably connected in the through hole. The bottom of the limiting column 8 is fixedly connected with the upper pressing plate 6. A strip-shaped opening is arranged on the top plate, and the strip-shaped opening is used for the passing of the limiting column 8. The setting of the limiting column 8 can ensure that the moving state of the lower pressing plate 4 is more stable, and ensure that it can move smoothly in the vertical direction.
[0031] In other preferred embodiments, a limiting roller 2 is arranged between the straightening station and the pre-straightening station. The limiting roller 2 is arranged in two groups, and a limiting space is formed between the two limiting rollers 2. The limiting space is used for the passing of the plate. Anti-skid protrusions are arranged on the surface of the limiting roller 2, and the anti-skid protrusions abut against the surface of the plate. Ratchet sets 11 are arranged on both sides of the limiting roller 2, and the ratchet sets 11 are used for controlling the one-way rotation of the limiting roller 2. Through the arrangement of the limiting roller 2, after the plate is pushed to the straightening station, the plate can be prevented from moving backward during the return movement of the lower pressing plate 4 through the action of the limiting roller 2.
[0032] The ratchet set 11 includes a ratchet and a ratchet tooth. The ratchet rotates synchronously with the limiting roller 2. The ratchet is rotatably connected to the first lifting frame. The ratchet tooth is arranged on the first lifting frame. The first lifting frame is used for controlling the distance between the two limiting rollers 2, so as to adapt to plates of different thicknesses.
[0033] In other preferred embodiments, the straightening station includes two groups of fixing frames and two groups of second lifting frames 10. The second lifting frame 10 is arranged on the fixing frame through a lifting column 9 and can be lifted. A fixed pressing roller 1 is arranged between the two fixing frames. A pressing roller 1 is arranged between the two lifting frames. Through the arrangement of this structure, plates of different thicknesses can be adapted.
[0034] In other preferred embodiments, a detection assembly is arranged on the side of the straightening station away from the pre-straightening station. The detection assembly includes a vertical plate, a vertical column, and a detection plate. The vertical column is arranged on one side of the vertical plate. The vertical column is sequentially provided with a first positioning plate, a first return spring, a first detection plate, a limiting sleeve, a second detection plate, a second return spring, and a second positioning plate from top to bottom. The first detection plate and the second detection plate are both slidably connected to the vertical column. The first detection plate and the second detection plate are fixedly connected with a drawing pen 15 near one side of the vertical plate. A recording plate 14 is arranged on the vertical plate. The recording plate 14 is used for recording the up-and-down floating state of the drawing pen 15. Through the arrangement of this structure, the drawing pen 15 can record the fluctuation state of the thickness of the straightened plate on the recording plate 14. That is, when the trace drawn by the drawing pen 15 on the recording plate 14 remains unchanged, it indicates that the thickness state of the plate is stable, and the straightening station and the pre-straightening station are operating normally. When the trace drawn by the drawing pen 15 on the recording plate 14 fluctuates, it indicates that the thickness state of the plate is abnormal, and the straightening station and the pre-straightening station need to be adjusted.
[0035] The above merely describes preferred specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art, according to the technical solution and inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
