Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy plate bending, in particular to an indentation-free, environment-friendly bending die suitable for forming aluminum alloy plates. Background Art

[0002] Aluminum alloy plate is an industrial building material. Its different materials and surface treatment methods make it widely used in various industries. For example, it can be found in aircraft structures, rivets, missile components, truck wheels, packaging and other fields. When bending aluminum alloy plates, bending molds are needed to bend the aluminum alloy plates.

[0003] After searching, the patent number is CN104874685B, and the name is a utility model of a pneumatic markless bending mold for aluminum alloy plates. It includes: through research and analysis, it is found that although it prevents the surface of the workpiece from being scratched and greatly improves the surface quality of the workpiece, it still has the following disadvantages to a certain extent.

[0004] For example, when the aluminum alloy sheet is bent, it is not capable of accurately bending the aluminum alloy sheet. Therefore, when the aluminum alloy sheet is bent, high pressure is likely to occur, and the bending pressure cannot be accurately controlled, resulting in inconsistent quality of the bent sheet, which reduces the bending effect. In addition, it does not have a good anti-indentation effect. Therefore, when the aluminum alloy sheet is bent, the aluminum alloy sheet is not easy to slide downward, causing the downward pressure of the pressing die to be too high, which makes indentations easily appear on the surface of the aluminum alloy sheet. In order to solve the above technical problems, we have designed an indentation-free and environmentally friendly bending die suitable for aluminum alloy sheet forming. Utility Model Content

[0005] The purpose of the utility model is to provide an indentation-free, environmentally friendly bending mold suitable for forming aluminum alloy plates, which has the advantages of accurately bending aluminum alloy plates and having a good anti-indentation effect, thereby solving the problems of not having the function of accurately bending aluminum alloy plates and not having a good anti-indentation effect.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an indentation-free, environmentally friendly bending mold suitable for forming aluminum alloy plates, comprising a base plate, the top of the base plate is connected to a lower mold by bolts, vertical plates are welded on the left and right sides of the top of the lower mold, and anti-indentation components are installed on the surface of the vertical plates, the rear side of the top of the base plate is connected to an L-shaped plate by bolts, the top of the L-shaped plate is connected to a hydraulic cylinder by bolts, the bottom end of the hydraulic cylinder passes through the inner cavity of the L-shaped plate and is connected to an upper mold by bolts, and buffer monitoring components are installed on the left and right sides of the top of the base plate.

[0007] Preferably, the buffer monitoring assembly includes a moving rod, the left and right sides of the upper mold are connected with short plates by bolts, the top of the moving rod is fixedly connected to the bottom of the short plate by bolts, a circular plate is welded to the bottom end of the moving rod, the left and right sides of the top of the bottom plate are connected with a buffer shell by bolts, and a buffer spring is welded to the bottom of the inner cavity of the buffer shell.

[0008] Preferably, a moving plate is welded to the top of the buffer spring, and a pressure sensor is connected to the top of the moving plate via bolts.

[0009] Preferably, the anti-indentation assembly includes a rotating rod, a mounting groove is opened on one side of the vertical plate, the front and rear ends of the rotating rod are movably connected to the inner wall of the mounting groove through bearings, the surface fixed sleeve of the rotating rod is provided with a protective sleeve, the surface movable sleeve of the protective sleeve is provided with a limiting ring, and one side of the limiting ring is connected to a telescopic rod by bolts.

[0010] Preferably, one end of the connecting telescopic rod away from the limiting ring penetrates into the interior of the vertical plate, and a positioning spring is movably sleeved on the surface of the connecting telescopic rod. Both ends of the positioning spring are respectively welded to the surface of the limiting ring and the inner wall of the mounting groove.

[0011] Preferably, stable telescopic rods are provided through both left and right sides of the top of the L-shaped plate, and the bottom ends of the stable telescopic rods are fixedly connected to the top of the upper mold by bolts.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model has the advantage of accurately bending the aluminum alloy plate by cooperating with the buffer shell, the circular plate, the moving rod, the pressure sensor, the moving plate and the buffer spring. When the aluminum alloy plate is bent, the moving rod drives the circular plate to move downward so that the circular plate can contact the top of the pressure sensor, thereby applying pressure to the pressure sensor and monitoring the bending pressure in real time, thereby effectively controlling the bending pressure. At the same time, the moving plate moves downward so that the buffer spring can contract, thereby providing buffer protection for the upper mold.

[0014] 2. The utility model has the advantage of good anti-indentation effect through the cooperation of the protective cover, the limit ring, the rotating rod, the positioning spring and the connecting telescopic rod. When the aluminum alloy plate is bent, the limit ring is pushed to squeeze the positioning spring to shorten the connecting telescopic rod, and the aluminum alloy plate is placed on the rotating rod. The limit ring is loosened so that the limit ring can limit the aluminum alloy plate. When the upper mold bends the aluminum alloy plate, the rotating rod rotates to allow the aluminum alloy plate to slide downward, so that the upper mold will not exert too much pressure on the surface of the aluminum alloy plate, effectively preventing indentations on the aluminum alloy surface.
