Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum sheet cutting technology, and more specifically, to a thin sheet cutting device. Background Technology
[0002] In modern industrial production, aluminum is widely used in various fields due to its advantages such as light weight and corrosion resistance. Aluminum sheets are usually supplied in coil form and need to be uncoiled and leveled before further processing. After uncoiling, the aluminum sheet is passed through a series of leveling rollers to eliminate internal stress and bending, ensuring that the surface of the aluminum sheet is flat. However, in the subsequent cutting process, how to accurately cut the aluminum sheet into rectangular aluminum plates of predetermined dimensions has become a technical challenge.
[0003] Traditional aluminum sheet cutting equipment typically uses fixed or moving blades to cut aluminum sheets. These methods share a common problem: the aluminum sheet is not securely fixed during the cutting process, making it prone to displacement and resulting in oblique cuts—that is, the cutting line is not perpendicular to the edge of the aluminum sheet. This leads to irregular shapes in the finished aluminum sheet, affecting product quality and subsequent use. This problem is particularly pronounced in high-speed production lines, as the rapidly moving aluminum sheet is more susceptible to mechanical errors.
[0004] Furthermore, some existing improvement solutions attempt to address the aforementioned problems by adjusting the cutting angle, but their effectiveness is limited and they increase equipment complexity and maintenance costs. Therefore, there is an urgent market need for a simple yet effective cutting device that can ensure high production efficiency while maintaining the cutting quality of aluminum plates, especially preventing oblique cuts. Utility Model Content
[0005] The purpose of this invention is to provide a thin sheet cutting device that can effectively avoid the problem of oblique cutting and improve the cutting quality of aluminum sheets.
[0006] This utility model is achieved through the following technical solution:
[0007] A thin sheet cutting device includes a worktable, on which a conveyor belt, a deviation correction and limiting mechanism, a cutting mechanism, and a guiding mechanism are sequentially arranged. The deviation correction and limiting mechanism includes a deviation correction plate and a limiting plate symmetrically arranged. The deviation correction plate is inclined, with one end of the deviation correction plate close to the conveyor belt and the other end of the deviation correction plate fixedly connected to the limiting plate. A cylinder is arranged on one side of the two limiting plates facing away from each other. The cutting mechanism includes a cutter and an electric telescopic rod. A support frame is arranged on the worktable, and the electric telescopic rod is mounted on the support frame. The drive end of the electric telescopic rod is connected to a mounting plate, and the cutter is arranged at the bottom of the mounting plate.

Several springs are provided between the pressure plate and the horizontal plates, and the horizontal surface of the lower surface of the pressure plate is lower than the horizontal surface of the bottom end of the cutter.
[0009] Furthermore, the top of the pressure plate is provided with multiple positioning rods, the other end of which is movably connected to the horizontal plate, and the multiple positioning rods are distributed in a ring at equal intervals.
[0010] Furthermore, an elastic pad is provided at the bottom of the pressure plate.
[0011] Furthermore, a guide rod is provided on the top of the mounting plate, and the other end of the guide rod is fixedly connected to the support frame. The guide rod is a telescopic rod.

[0028] Example 1
[0029] like Figures 1-4 As shown, this embodiment provides a thin plate cutting device, including a workbench 1. The workbench 1 is sequentially equipped with a conveyor belt 2, a deviation correction and limiting mechanism 3, a cutting mechanism 4, and a guiding mechanism 5. The deviation correction and limiting mechanism 3 includes a deviation correction plate 31 and a limiting plate 32 symmetrically arranged. The deviation correction plate 31 is inclined, with one end of the deviation correction plate 31 close to the conveyor belt 2 and the other end of the deviation correction plate 31 fixedly connected to the limiting plate 32. A cylinder 33 is provided on one side of the two limiting plates 32 facing away from each other. The cutting mechanism 4 includes a cutter 42 and an electric telescopic rod 41. A support frame 11 is provided on the workbench 1, and the electric telescopic rod 41 is mounted on the support frame 11. The driving end of the electric telescopic rod 41 is connected to a mounting plate 43, and the cutter 42 is provided at the bottom of the mounting plate 43.
[0030] The correction plate 31 is tilted. When the aluminum sheet is transported from the conveyor belt 2 to the correction and limiting mechanism 3, the tilted aluminum sheet is restored to a horizontal state with the help of the correction plate 31 and is limited by the limiting plate 32 to prevent the aluminum sheet from deviating. In addition, the limiting plate 32 is driven by the cylinder 33 to move, which in turn drives the correction plate 31 to move, so as to correct and limit the aluminum sheet of different widths. When the aluminum sheet is transported to the bottom of the cutter 42, the cutter 42 is lowered by the electric telescopic rod 41 to cut the aluminum sheet. The cut aluminum sheet is then guided and collected by the guide mechanism 5.
[0031] In this embodiment, the mounting plate 43 has horizontal plates 44 on both sides, and a pressure plate 45 is provided below the horizontal plates 44. Several springs 46 are arranged between the pressure plate 45 and the horizontal plates 44. The horizontal plane of the lower surface of the pressure plate 45 is lower than the horizontal plane of the bottom end of the cutter 42. When the electric telescopic rod 41 lowers the mounting plate 43, it simultaneously lowers the pressure plate 45 and the cutter 42. Before the cutter 42 cuts the aluminum sheet, the pressure plate 45 contacts the aluminum sheet first. When the cutter 42 cuts, the springs 46 are compressed, causing the pressure plate 45 to press firmly against the surface of the aluminum sheet, thus fixing the aluminum sheet and preventing it from shifting during cutting, thereby improving cutting accuracy.
[0032] In this embodiment, the pressure plate 45 is provided with a plurality of positioning rods 47 on its top. The other end of each positioning rod 47 is movably connected to the horizontal plate 44, and the plurality of positioning rods 47 are distributed in a ring at equal intervals. The positioning rods 47 can improve the stability of the pressure plate 45 during compression.
[0033] In this embodiment, an elastic pad is provided at the bottom of the pressure plate 45. The elastic pad can prevent the pressure plate 45 from causing wear on the surface of the aluminum sheet.
[0034] In this embodiment, a guide rod 48 is provided on the top of the mounting plate 43, and the other end of the guide rod 48 is fixedly connected to the support frame 11. The guide rod 48 is a telescopic rod. The guide rod 48 can improve the stability of the mounting plate 43 when it moves and improve the cutting accuracy of the cutter 42.
[0035] In this embodiment, the workbench 1 has a cutting groove 12 on its surface, and the cutting groove 12 cooperates with the cutter 42.
[0036] In this embodiment, the guiding mechanism 5 includes symmetrically arranged guide plates 51, and a second cylinder 52 is provided on one side of the two guide plates 51 facing away from each other. The second cylinder 52 and the guide plates 51 cooperate to guide aluminum sheets of different widths.
[0037] In this embodiment, a dust collection hopper 13 is provided on the inner side of the support frame 11, and a dust collection box 14 is provided below the cutting groove 12. The dust collection hopper 13 is connected to the input end of the dust pump via a flexible hose, and the output end of the dust pump is connected to the dust collection box 14 via a conduit. The dust collection hopper 13, the dust collection box 14, and the dust pump work together to collect aluminum chips during the cutting process, preventing excessive aluminum chips from affecting cutting accuracy. The dust pump is installed inside the workbench 1.
[0038] The working principle of a thin sheet cutting device is as follows: Cylinder 33 drives the limiting plate 32 to move, so that the width between the two limiting plates 32 is the same as the width of the aluminum sheet. The aluminum sheet is conveyed to the correction plate 31 by the conveyor belt 2. The correction channel formed between the correction plates 31 is used to correct the deviation of the aluminum sheet. The aluminum sheet passes through the limiting plate 32, the cutter 42 and the guide plate 51 in sequence. When the required cutting length of the aluminum sheet is reached, the electric telescopic rod 41 drives the mounting plate 43 to descend, and simultaneously drives the pressure plate 45 and the cutter 42 to descend. After the pressure plate 45 contacts the aluminum sheet, it presses firmly on the surface of the aluminum sheet, and the cutter 42 cuts the aluminum sheet.
[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
