Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of aluminum alloy plate production, in particular to a correction tool for aluminum alloy thin plates. Background Art
[0002] After quenching, the aluminum alloy sheet is transported by rollers. Because the sheet is thin, it is generally deformed a lot after quenching. When the head and tail of the sheet are deformed, an inverted shape is formed. The inverted aluminum alloy sheet is easily inserted into the roller, causing the plate to be stuck. Manual intervention and shutdown for cleaning are required, which increases the workload of workers and reduces production efficiency. At the same time, it causes damage to the roller and aluminum alloy sheet, resulting in certain economic losses. Utility Model Content
[0003] The purpose of the utility model is to provide a correction tool for aluminum alloy thin plates, which can shape the aluminum alloy thin plates in advance so that the front and rear ends thereof are slightly tilted upward, thereby reducing the possibility of the aluminum alloy thin plates being knocked downward toward the bottom of the roller due to quenching deformation, thereby reducing the probability of the aluminum alloy thin plates being stuck in the roller, thereby reducing the workload of workers and improving work efficiency.
[0004] In order to achieve the above-mentioned purpose, the utility model provides a correction tool for aluminum alloy thin plates, including a bracket, a pressure plate assembly rotatably mounted on the bracket, and a rotating drive device for driving the pressure plate assembly to rotate; the pressure plate assembly includes a pressure plate frame rotatably mounted on the bracket, and a pressure plate and a clamping plate are movably mounted on the pressure plate frame up and down, forming a clamping area between the pressure plate and the clamping plate; the pressure plate frame is also provided with a clamping drive device for driving the pressure plate and the clamping plate to clamp each other.
[0005] After adopting the above structure, the clamping drive device drives the pressure plate and the clamping plate to clamp the front end or the rear end of the aluminum alloy sheet, and then the rotary drive device drives the pressure plate assembly to rotate accordingly, so that the clamping end forms an upward curved arc, thereby causing the aluminum alloy sheet to slightly warp upward, reducing the situation where it knocks downward toward the bottom of the roller due to quenching deformation, thereby reducing the probability of it being stuck in the roller, thereby reducing the workload of workers and improving work efficiency.
[0006] Preferably, the pressing plate is fixed on the pressing plate frame, the clamping plate is slidably mounted on the pressing plate frame, and the clamping drive device is fixed on the pressing plate frame and its output shaft is connected to the clamping plate. Through this arrangement, the controllability of the clamping position can be achieved and the structure of the clamping drive device can be simplified.
[0007] Preferably, the pressure plate frame includes a left column and a right column disposed opposite each other, the pressure plate being fixed to the bottom of the left and right columns and connecting the left and right columns; a slideway is vertically provided at the center axis of the left and right columns, and a slide rod is mounted in the slideway for vertical sliding, the bottom of the slide rod extending out of the slideway and fixed to the clamping plate; the top of the slide rod is connected to the clamping drive device. This arrangement ensures that the pressure plate and the clamping plate are positioned relatively accurately when clamped, ensuring the stability of the clamping.
[0008] Preferably, the left and right sliding rods are fixedly connected by a limit rod and share the same clamping drive device. This arrangement ensures the stability of the clamping plate lifting and lowering, while reducing the input amount of the clamping drive device, thereby reducing the device cost.
[0009] Preferably, the left column and the right column are provided with limit slots on the opposite side walls, and the limit rod is slidably installed in the limit slots. Through this arrangement, a limit slideway can be provided for the limit rod lifting to ensure that the lifting is stable.
[0010] Preferably, a stopper is installed at the top of the slideway in an adjustable position; the top of the slide rod abuts against the bottom of the stopper. Adjustment of the stopper can compensate for the shortcomings of the clamping drive device and avoid excessive clamping force due to errors, which may cause damage to the aluminum alloy sheet.
[0011] Preferably, the pressing plate is a pressing roller. The pressing plate is set as a pressing roller to ensure that there is sufficient contact area between the pressing roller and the aluminum alloy sheet during bending to avoid obvious creases.
[0012] Preferably, the rotation axis of the pressing plate frame is coaxial with the central axis of the pressing roller. Through this design, the rotation time can be reduced. When the pressing plate frame rotates, the pressing roller only rotates without changing in height, thereby reducing the bending radius of the aluminum alloy sheet and ensuring the bending effect.
[0013] Preferably, the pressing roller is a rubber roller; an elastic layer is provided at the contact position between the upper surface of the clamping plate and the pressing roller. This arrangement avoids the bending process, friction on the aluminum alloy sheet, causing scratches on the surface of the aluminum alloy sheet and affecting the appearance.
[0014] Preferably, the bracket is provided with arc-shaped slideways on the left and right sides of the pressure plate frame to limit the forward and backward rotation of the pressure plate frame, and limit posts are provided on the left and right sides of the pressure plate frame corresponding to the arc-shaped slideways, and the limit posts are slidably installed in the arc-shaped slideways. Through this arrangement, the pressure plate assembly can be more stable when swinging back and forth.

DETAILED DESCRIPTION
[0022] The present invention will be further described below with reference to the accompanying drawings.
[0023] The orientations mentioned in this specification are based on the orientations of the aluminum alloy thin plate correction tool of the present invention during normal operation, and do not limit the orientations during storage and transportation. They only represent relative positional relationships, not absolute positional relationships.
[0024] like Figure 1 、 Figure 2 and Figure 3 As shown together, a correction tool for aluminum alloy thin plates includes a bracket 1, a pressure plate assembly 2 rotatably mounted on the bracket 1, and a rotation driving device 3 for driving the pressure plate assembly 2 to rotate.
[0025] The platen assembly 2 includes a platen frame 21 rotatably mounted on the bracket 1. Axles 210 are fixed to the left and right sides of the platen frame 21. The shafts 210 are rotatably mounted on the bracket 1 via bearings. A platen 22 and a clamping plate 23 are movably mounted on the platen frame 21, forming a clamping area between the platen 22 and the clamping plate 23. The platen frame 21 is also equipped with a clamping drive 24 that drives the platen 22 and the clamping plate 23 to tighten or loosen.
[0026] In order to facilitate the aluminum alloy sheet conveyed from the roller to directly enter the clamping area, the bracket 1 is fixed on both sides of the roller; the pressure plate 22 is located above the roller conveying surface, and the clamping plate 23 is located below the roller conveying surface.
[0027] The pressing plate 22 and the clamping plate 23 can be movably mounted on the pressing plate frame 21, or either one of them can be movably mounted on the pressing plate frame 21. In this embodiment, in order to achieve controllability of the clamping position and simplify the structure of the clamping drive device 24, the pressing plate 22 is fixed to the pressing plate frame 21, while the clamping plate 23 is slidably mounted on the pressing plate frame 21. The clamping drive device 24 is fixed to the pressing plate frame 21 and its output shaft is connected to the clamping plate 23. The clamping drive device 24 controls the up and down sliding of the clamping plate 23, thereby moving it closer to and away from the pressing plate 22 to clamp or release the aluminum alloy sheet.
[0028] The specific structure is as follows: the pressure plate frame 21 includes a left column 211 and a right column 212 that are arranged opposite to each other on the left and right sides. The outer sides of the left column 211 and the right column 212 are rotatably mounted on the bracket 1 on their corresponding sides through a rotating shaft 210. The pressure plate 22 is fixed to the bottom of the left column 211 and the right column 212 and connects the left column 211 and the right column 212. A slideway is vertically opened at the central axis position of the left column 211 and the right column 212. A slide bar 231 is installed in the slideway for sliding up and down. The bottom of the slide bar 231 extends out of the slideway and is fixed to the clamping plate 23; a clamping drive device 24 is fixed to the top of the left column 211 and the right column 212. In this embodiment, the clamping drive device 24 is an oil cylinder. In actual applications, an electric cylinder or a pneumatic cylinder can also be used. The output shaft of the clamping drive device 24 extends into the slideway and is fixed on the slide bar 231 . The extension and retraction of the output shaft of the clamping drive device 24 controls the lifting and lowering of the slide bar 231 , thereby controlling the clamping plate 23 to approach and move away from the pressure plate 22 .
[0029] To ensure synchronous lifting and lowering of the two sides of the clamping plate 23 and reduce the number of clamping drive devices 24 required, the left and right slide bars 231 share the same clamping drive device 24. The tops of the two slide bars 231 are fixedly connected by a limit rod 232. The clamping drive device 24 is fixed to the pressure plate frame 21, and its output shaft is fixed to the limit rod 232.
[0030] To ensure greater stability when the clamping plate 23 slides up and down, limit slots 213 are provided on the opposing walls of the left and right columns 211 and 212. Limit rods 232 are mounted within these slots for vertical sliding. The tops of the left and right columns 211 and 212 are fixedly connected by a connecting rod 214. The clamping drive 24 is fixedly mounted in the middle of the connecting rod 214. The output shaft of the clamping drive 24 passes downward through the connecting rod 214 and is fixed to the limit rod 232.
[0031] To ensure the adjustable clamping force of clamping plate 23, a stopper 215 is installed at an adjustable position at the top of the slideway. The top of slide bar 231 abuts the bottom of stopper 215. A bolt is screwed onto the top of the slideway. The bottom of the bolt penetrates into the slideway and is fixed to stopper 215. The position of stopper 215 is controlled by controlling the length of the bolt inserted into the slideway. Stopper 215 limits the maximum rise position of slide bar 231, allowing the minimum gap between clamping plate 23 and pressure plate 22 to be adjusted according to the thickness of the plate, thereby adjusting the clamping force.
[0032] The rotary drive device 3 in this embodiment is an oil cylinder. In actual applications, an electric cylinder or a pneumatic cylinder can also be used. The fixed end of the rotary drive device 3 is hinged on the bracket 1, and its output end is hinged on the pressure plate frame 21. Through the extension and retraction of the rotary drive device 3, the pressure plate frame 21 is controlled to rotate around the rotating shaft 210 to achieve upward bending of the aluminum alloy sheet.
[0033] Because the pressing plate 22 exerts pressure and friction on the aluminum alloy sheet during upward bending, in order to avoid causing obvious creases or friction marks on the aluminum alloy sheet, the pressing plate 22 is a pressing roller. The pressing roller can increase the contact area between the aluminum alloy sheet and the round roller, so that the aluminum alloy sheet forms a smooth arc after bending, thereby avoiding affecting the appearance of the aluminum alloy sheet.
[0034] The rotating shaft 210 is coaxially arranged with the pressing roller. With this arrangement, when the pressing plate frame 21 rotates, the pressing roller only rotates and does not change in height, thereby reducing the bending radius of the aluminum alloy sheet and ensuring the bending effect.
[0035] To prevent the pressure roller and clamping plate 23 from rubbing against the aluminum alloy sheet during clamping and causing scratches on its surface, the pressure roller is a rubber roller, and an elastic layer is provided on the upper surface of the clamping plate 23 where it contacts the pressure roller. The rubber roller and the elastic layer increase the friction with the aluminum alloy sheet, thereby increasing the clamping force and preventing it from slipping during the bending process.
[0036] Furthermore, in order to ensure that the pressure plate frame 21 is more stable when it swings back and forth, an arc-shaped slide 11 is provided on the left and right sides of the pressure plate frame 21 on the bracket 1 to limit the forward and backward rotation of the pressure plate frame 21. Limiting columns 25 are provided on the left and right sides of the pressure plate frame 21 corresponding to the arc-shaped slide 11, and the limiting columns 25 are slidably installed in the arc-shaped slide 11.
[0037] Fix the bracket 1 on both sides of the roller conveyor. After the front end of the aluminum alloy sheet is conveyed from the roller conveyor, it enters between the pressing plate 22 and the splint 23. Then, the clamping drive device 24 drives the pressing plate 22 and the splint 23 to clamp the aluminum alloy sheet. Then, the rotary drive device 3 drives the pressing plate frame 21 to rotate forward, thereby bending the clamping end upward, and realizing the upward bending of the front end of the aluminum alloy sheet. The clamping drive device 24 drives the pressing plate 22 and the splint 23 to release the aluminum alloy sheet. Then, the rotary drive device 3 drives the pressing plate frame 21 to reset. The roller conveyor continues to convey the aluminum alloy sheet forward. When the tail end of the aluminum alloy sheet enters between the pressing plate 22 and the splint 23, the clamping drive device 24 drives the pressing plate 22 and the splint 23 to clamp the aluminum alloy sheet. The rotary drive device 3 drives the pressing plate frame 21 to rotate backward, thereby bending the clamping end upward, and realizing the upward bending of the rear end of the aluminum alloy sheet. The bent aluminum alloy sheet is as shown in FIG. Figure 4 shown.
[0038] The utility model discloses a correction tool for aluminum alloy thin plates, which solves the technical problem in the prior art that aluminum alloy thin plates are easily deformed after quenching and form an inverted shape, and the inverted aluminum alloy thin plates are easily inserted into the roller, thereby causing plate jams, increasing the workload of workers, and reducing work efficiency. The utility model shapes the aluminum alloy thin plates in advance so that the front and rear ends thereof are slightly tilted upward, thereby reducing the situation in which the aluminum alloy thin plates are knocked downward toward the bottom of the roller due to quenching deformation, thereby reducing the probability of the aluminum alloy thin plates being jammed into the roller, thereby reducing the workload of workers and improving work efficiency.
[0039] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
