Technical Field

[0001] The utility model relates to an online flattening machine for extruded bow-shaped plates, in particular to an online tablet press for magnesium alloy thin plates, and belongs to the technical field of mechanical processing equipment. Background Art

[0002] With the continuous development of science and technology, people in the fields of computers, communications, consumer electronics, and other fields no longer only focus on performance, but also begin to pay attention to its lightweight applications, such as laptops, tablets, and mobile phones. Currently, magnesium alloys are light weight, high strength, good thermal conductivity and electrical conductivity, and have excellent electromagnetic shielding and good machinability, making them an ideal material for 3C electronic products.

[0003] However, due to the complicated process in the preparation of magnesium alloy products, which requires multiple rolling, heat treatment, shearing, grinding and other processes, the production efficiency is low and the cost is high, which limits the further widespread application of magnesium alloy products. Among them, hot-extruded magnesium alloy sheets are prone to deformation before rolling, and extrusion defects such as bow, wave, and sickle shape need to be sheared off before hot rolling, further reducing the yield and increasing the cost, which greatly limits the promotion and application of magnesium alloy sheets in the industry. The processing technology problems of magnesium alloys have become a stumbling block for improving the quality and reducing the cost of magnesium alloys and expanding their applications, but the market demand for magnesium alloy sheets has not weakened. Therefore, there is an urgent need for a processing equipment that can flatten the magnesium alloy sheet after the hot extrusion process is completed to avoid shearing off due to deformation of the edge of the sheet, resulting in waste of raw materials.

[0020] Please participate Figure 1 and 2 As shown, an online flattening machine for extruded arched plates includes a fixed frame 1, a frame consisting of an X-axis square tube 100, a Y-axis square tube 200, and a Z-axis square tube 300. The four square tubes at the bottom are two X-axis square tubes 100 and two Y-axis square tubes 200, forming a bottom square frame. Two crossbeams 400 in the upper Y-axis direction are installed between the two X-axis square tubes 100.

[0021] like Figure 1 As shown, the cylinder 2 is bolted to the crossbeam 400 of the fixed frame. The lower end of the cylinder connecting shaft 8 of the cylinder 2 is hinged to the movable roller connecting plate 9 via a rotating shaft. The movable roller connecting plate 9 is arranged in the X-axis direction, and two limit screws 10 are installed in holes at both ends of the movable roller connecting plate 9. A pair of limit plates 5 are arranged along the Y-axis, with their ends welded to the Z-axis square tube 300. The limit plates 5 are located opposite the limit screws 10 and are used to limit the travel of the movable roller connecting plate 9.

[0022] The upper ends of a pair of movable pull rods 3 are hinged to two Z-axis square tubes 300 on the rear side of the fixed frame 1 through a rotating shaft;

[0023] The movable pressing roller 4 is arranged along the X-axis direction and is located below the movable roller connecting plate 9. Both ends of the movable pressing roller 4 are connected to the lower end of the movable pull rod 3 through bearing seats;

[0032] Working principle and steps:

[0033] The magnesium alloy cast bar is deformed at the edge after being extruded into a plate due to various reasons. To solve the problem of increased production cost caused by serious deformation, a flattening device is added at the outlet of the hot extrusion equipment about 500mm away to straighten the magnesium alloy plate.

[0034] Place the front end of the hot extruded plate on the fixed pressure roller 6, turn on the cylinder 2 button, adjust the distance between the movable pressure roller 4 and the fixed pressure roller 6 according to the thickness of the plate to ensure that the flattened plate meets the processing requirements, tighten the limiting screw 10 to fix the gap, adjust the distance between the limiting guide rollers 7, and with the hot extrusion, the plate is sequentially pulled through the flattening machine to complete the online straightening and make a roll.
