Abstract
The invention discloses belongs to the technical field of metal material production and in particular relates to a trimming-free production technique of magnesium alloy plates. The production technique is as follows: producing a circular magnesium alloy blank; piercing the circular magnesium alloy blank through a skew piercing machine to form a pierced billet; inserting a core rod into the pierced billet; rolling the pierced billet through a reversible skew rolling machine repeatedly for multiple times to form a hollow billet; thinning the wall of the hollow billet through a drawing machine, sizing the hollow billet and finishing the sized hollow billet to form a magnesium alloy pipe; splitting the magnesium alloy pipe through a splitting machine; and flattening the magnesium alloy pipe through a flattening machine to form a magnesium alloy plate.
Description
Technical field
The invention belongs to metal material production technical field, be specifically related to a kind of magnesium alloy plate without trimming production process.
Background technology
At present, following several magnesium alloy plate production technology is mainly contained.
1. extrude slab-cutting method: extrusion is by the magnesium alloy blank of casting, after surface treatment, utilizes extruder to be squeezed into certain thickness slab.Then adopt flush cut mode, the top layer of its one or both sides is removed, makes it reach the thickness of regulation, and clean out the defects such as face crack, become magnesium alloy plate.The shortcoming of this technique is: the flush cut difficulty of (1) magnesium alloy slab, and yield rate is low; (2) production wide format magnesium alloy plate is difficult to; (3) magnesium alloy cuts damage amount greatly, and lumber recovery is low; (4) the flush cut time is long, and production efficiency is low.
2. extrusion tube blank-expansion-rolling: this method is by the magnesium alloy blank of casting, after surface treatment, utilizes extruder to be squeezed into the pipe of certain size.Then adopt cutting mode, be launched into slab, and clean out the defects such as face crack.Then utilize rolling equipment by it at a certain temperature, multi-pass repeat-rolling becomes regulation thick plates material.The shortcoming of this technique is: (1) process route is long, and equipment investment is many; (2) rolling pass is many, and rolling quality is unstable, and magnesium alloy cuts damage amount greatly, and lumber recovery is low; (3) production wide format magnesium alloy plate is difficult to; (4) production cycle is long, and production efficiency is low.
3. Direct Rolling method: this method is by the magnesium alloy blank of casting, after surface treatment, utilizes the milling train of different size, by multiple rolling process such as cogging, roughing, finish rolling, is rolled into the sheet material of certain size.The shortcoming of this technique is: (1) process route is long, and equipment investment is many; (2) rolling pass is many, and rolling quality is unstable, and magnesium alloy cuts damage amount greatly, and lumber recovery is low; (3) production cycle is long, and production efficiency is low.
4. casting-rolling: this method is magnesium alloy made-up belt volume casting produced, and after surface treatment, utilizes milling train, by multiple rolling pass, be rolled into the magnesium alloy strip coil of certain size, then utilize Special Equipment to be flattened by magnesium alloy strip coil, cut off, become magnesium alloy plate.The shortcoming of this technique is: (1) rolling casting technology is unstable, and lumber recovery is low; (2) continuous production is strong, needs to ensure enough output; (3) coil rolling technical sophistication, production stability is poor, and it is large that magnesium alloy cuts damage amount; (4) not easily wide plate is produced.
Summary of the invention
The object of this invention is to provide that a kind of technique is simple, organization of production is flexible, cost is low, efficiency is high, energy consumption is low, magnesium alloy is cut damage and measured little magnesium alloy plate production technology.
The present invention adopts oblique milling-flattening method to produce magnesium alloy plate, it is characterized in that:
By magnesium alloy circle blank, after surface treatment, be heated to 200 DEG C ~ 500 DEG C, utilize Mannesmann piercing mill that magnesium alloy circle blank is rolled into the hollow forging of 5 ~ 25mm thickness; The roller temperature of Mannesmann piercing mill remains on 150 DEG C ~ 300 DEG C; Then long plug is penetrated magnesium alloy hollow forging, the temperature of long plug remains on 100 DEG C ~ 200 DEG C; The magnesium alloy hollow forging putting on long plug enters reversible skew rolling mill and carries out reciprocal multi-pass rolling, hollow forging rolling is become magnesium alloy hollow billet that thickness is 0.5 ~ 1.5mm; The roller temperature of reversible skew rolling mill remains on 150 DEG C ~ 300 DEG C; Magnesium alloy hollow billet by drawbench, obtains magnesium-alloy tube together with long plug after subtracting wall, sizing and polishing; Magnesium alloy pipe carries out subdivision after de-rod, flattening, shearing become magnesium alloy plate.
Advantage of the present invention and good effect are: (1) realize magnesium alloy materials without side, when eliminating magnesium alloy plate and belt rolling, edge crack phenomenon, reduces metal loss effectively; (2) roll piercing and the reversible oblique milling of magnesium alloy materials is realized; (3) large scale, high-quality magnesium alloy plate can be obtained; (4) the further advantage of this technique is: technological process is short, production equipment is few, tissue is produced flexibly, energy ezpenditure is low, and working condition is good.
