Forming device and processing method of light-alloy wide sheet

Abstract

The invention discloses a forming device of a light-alloy wide sheet. The forming device of the light-alloy wide sheet comprises a die and a punch which are arranged in a corresponding mode, wherein a charging barrel used for storing blank is arranged in the die, the charging barrel is sleeved with a heating coil for heating the blank, and a forming part of a spiral structure is arranged at the bottom of the charging barrel; and multiple force transfer shafts which face the die are connected with the punch, a downward pressing part used for squeezing the blank is arranged on the force transfer shafts, the structure of the downward pressing part is the same as that of the forming part, a solid part of the downward pressing part corresponds to a hollow part of the forming part, thus when the solid part of the downward pressing part squeezes the blank to the interior of the hollow part of the forming part, the solid part of the downward pressing part coincides with the hollow part of the forming part, a hollow part of the downward pressing part and the hollow part of the forming part conduct squeezing separately to form a roll of spiral sheet metal, and the sheet metal is expanded to form the magnesium alloy wide sheet.

Description

technical field [0001] The invention relates to the technical field of forming light alloy plates, in particular to a forming device and a processing method for light alloy wide thin plates. Background technique [0002] As an important emerging engineering material, magnesium alloy has received more and more attention. But the existing use situation is far from exerting its potential advantages, and the actual industrial application is very small. The crystal structure of magnesium alloy is a close-packed hexagonal structure, and its plastic formability at room temperature is poor, so it is greatly restricted in practical applications. Magnesium alloy products are divided into cast magnesium alloys and wrought magnesium alloys. Wrought magnesium alloys mainly refine the structure and improve performance through thermal deformation, such as rolling and extrusion. Compared with cast magnesium alloys, wrought magnesium alloys have better comprehensive mechanical properties, ...

AI Technical Summary

Problems solved by technology

[0003] At present, in the industrial production of magnesium alloy wide sheets, the hot-extruded sheets are subjected to reciprocating hot-rolling, and the extrusion deformation method adopts the one-way extrusion method, which will result in limited grain refinement ability and easy There are problems such as uneven structure or even cracks. In order to obtain a magnesium alloy with a uniform and fine structure and optimized performance, it is usually necessary to perform multiple extrusions, which greatly increases the production cost. At the same time, only one piece of magnesium can be produced during extrusion. Alloy wide plate, low production efficiency
