Embodiment Construction

[0036] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] The invention provides a continuous extrusion and rolling device for ultra-thin wide-width magnesium alloy plates, which includes an extrusion device, a continuous rolling device and a leveling device, and the continuous rolling device is located between the extrusion device and the leveling device.

[0038] Such as figure 1 As shown, the extrusion device includes an extrusion barrel 2 and a "W"-shaped extrusion die 5 arranged at the bottom of the extrusion barrel 2. The inner wall of the extrusion barrel 2 and the "W"-shaped extrusion die 5 constitute a die cavity. It is used to place the magnesium alloy blank 8 to be extruded. Such as figure 2 As shown, the "W" type extrusion die 5 is provided with a "W" type gap 9, such as image 3 As shown, the "W" type gap 9 is composed of a flaring 10, an extrusion slit 11 and a discharge por...

Abstract

The invention discloses a wide magnesium alloy ultra-thin plate continuous extrusion device, which comprises an extrusion device, a continuous rolling plate device and a leveling device, wherein the extrusion device comprises an extrusion barrel and a W-shaped extrusion female die; a W-shaped gap is formed on the W-shaped extrusion female die; the continuous rolling plate device consists of a plurality of groups of rolling plate transfer rollers; each group of rolling plate transfer rollers consist of an upper rolling plate roller and a lower rolling plate roller; a W-shaped protrusion is formed on the upper rolling plate roller; a W-shaped groove is formed on the lower rolling plate roller; the leveling device consists of a plurality of groups of leveling rollers; each group of leveling rollers consist of an upper leveling roller and a lower leveling roller; the upper leveling roller and the lower leveling roller are cylindrical; the continuous rolling plate device is positioned between the extrusion device and the leveling device; and rolling surface curves tend to be flat in turn. Due to a continuous extrusion, rolling plate, leveling or continuous extrusion, rolling plate, rolling, leveling and rolling process, a magnesium alloy ultra-thin plate is continuously deformed and molded at one time, and the plate has bright and clean surface and dense internal structure.

Description

technical field [0001] The invention belongs to the field of plastic processing of metal materials and non-ferrous metals, and relates to a device capable of forming a wide-width magnesium alloy ultra-thin plate through extrusion, plate rolling or continuous rolling at one time, and also relates to an extrusion method using the device. Background technique [0002] High-performance structural materials are an important material basis for transportation, energy and power, resources and environment, electronic information, agriculture and construction, aerospace and national major projects, and are currently one of the most competitive high-tech new materials in the world. . Magnesium is currently the lightest metal among the most widely used structural metal materials. It not only has light weight, high specific strength and specific stiffness, good damping and vibration reduction, strong electromagnetic shielding, but also strong machinability and recyclability. Known as th...
