Description
Technical field
Method is shaped the present invention relates to a kind of sheet metal, and in particular to a kind of plate batch modularization side is to squeezing
Pressing formation method belongs to extrusion forming technology field.
Background technique
Sheet-metal member is to realize one of material and structure lightened main path, all in aerospace, automobile manufacture etc.
It is widely used in multi-field and demand cumulative year after year.The main method of extensive highly-efficient processing manufacture sheet metal at present
There are cold continuous rolling, continuous casting and rolling and casting etc..
Cold continuous rolling refers to the steel plate Jing Guo hot rolling, after pickling to remove oxide, carries out in Continuous mill train continuous
Cold deformation, by degreasing, annealing and etc. improve timber intensity, hardness, according to production requirement, the processes such as smooth, finishing of process
Drip molding is obtained, production efficiency is flow harden highest, that continuous cold deformation generates in steel rolling field, and steel plate can be made strong
Degree, hardness improve, but plasticity and toughness decline, punching performance deteriorate.
Continuous casting and rolling, which refers to for liquid molten steel to be put into conticaster, is made steel billet, and without cooling, one is kept the temperature in holding furnace
After the section time, it is put into hot tandem and carries out roll forming.This technique, which has, improves working conditions, is easy to implement mechanization and oneself
The characteristics of dynamicization.Compared to continuous cold rolling process, continuous casting and rolling has been significantly shorter the production cycle, but at present can only be in plate and band
It is applied in material, producible alloy is less, cannot especially produce the big sheet alloy of crystallization range, shape and rule
Malleable, surface accuracy be not poor for lattice.
After casting refers to metal bath through two rotation Casting Rollers with water-cooling system, into Hot Rolling Mill into
The process of row rolling.Compared with continuous casting and rolling, casting-rolling technology simplifies production procedure, shortens the production cycle, improves
Productivity.But the big sheet alloy of crystallization range cannot be equally produced, installation cost is higher, coarse grains and uneven,
The defects of mechanical performance is relatively poor, and surface is easy to appear striped, side is split.
In summary, it is relatively cumbersome in process to shape sheet metal method for conventional batch, to alloying component
It is required that also higher, structural homogenity and mechanical performance are also not ideal enough.Extrusion process is that one kind can produce long, linearity feature
The process of metal material is also used for shaping for sheet metal in recent years.Due to can get three-dimensional compressive stress state,
For inductile sheet alloy, the advantage of extrusion process is more obvious, but, sheet shape low there are die life
The bottlenecks such as dimension control difficulty, craft flexibility difference.
With urgent need of the numerous areas to lightweight and energy-saving and emission-reduction in recent years, the dosage of metal sheet is increasingly gradually
Increase, use scope and field are also widened therewith, it would be highly desirable to be improved prior art method and be accelerated to innovate, to adapt to produce in batches high property
The actual needs of energy plate.
Summary of the invention
The object of the present invention is to provide a kind of modular lateral compression manufacturing process of plate batch.In order to solve at present
Low efficiency present in industrial circle plate volume manufacturing process, process flow is long, energy consumption is excessive, craft flexibility is poor and quality
The serial bottleneck such as difficulty can be regulated and controled.Present invention employs the integrated technologies thoughts such as one-mold multiple-member, modularization, it is reasonably used
In the scientific design for squeezing mode structure, while realizing that fine grain is modified, only needing to change mould part structure can be in single pass
Direct extrusion molding goes out the plate of the plurality of specifications such as different cross section shape, size in short route, produces for efficient batch short route
Sheet metal provides a kind of new approaches.

The slotted hole 4-1 of quantity and structure is actually needed according to production, the floor 7 of corresponding construction in replaceable 4 slotted hole 4-1 of insert
It can be obtained the high-performance metal plate of plurality of specifications.
Method: the method through the following steps that realize:
Step 1: selecting different slotted hole 4-1 structures according to the shape for the sheet metal of being prepared and size equal-specification requirement
Insert 4 and floor 7；
Step 2: pedestal 3 is put on press bench and fixes, inner sleeve 5 is placed on the base 3；
Step 3: the insert 4 for being plugged floor 7 is put into the groove 5-1 of 5 side of inner sleeve；
Step 4: outer sleeve 6 is placed in the outside of pedestal 3, insert 4,5 assembly of inner sleeve, wherein sleeve hole 6-1 and 4 institute of insert
It interlinks at position, plays position-limiting action；
Step 5: inner sleeve 5 is sequentially placed into blank 2 and punch-pin 1；
Loading and shaping is carried out to punch-pin 1 Step 6: starting press machine, compressive deformation blank 2 sequentially radially flows into insert 4 respectively
Each floor 7 between shape chamber；
Step 7: being that forming terminates when punch-pin 1 is loaded at the top of pedestal 3, outer sleeve 6 and insert 4 are removed respectively, that is, can be taken off
The plurality of specifications plate of extrusion molding.
The method of the present invention it is specific following compared with prior art the utility model has the advantages that
One, the method for the present invention can reach in single pass extrusion process it is primary obtain plurality of specifications sheet metal product,
The actual effects purposes such as batch production；
Two, it is required according to plate specification and shape feature etc., can accordingly replace insert and rib structure and carry out modularization
Processing, the custom-made of specification plate, module needed for realizing are easily changed and recycle, and craft flexibility is higher；
Three, i.e. vertical with sheet material forming direction along the normal direction of plate horizontal plane due to loading direction, between each shape chamber mutually
Do not interfere.Width, thickness can be may customize by the design and adjustment of shape chamber sectional shape structure according to the actual requirement of product
A variety of different size shape board products that degree or odd-shaped cross section etc. have differences；
Four, the corner that loading direction and outflow direction are flowed through after blank compressive deformation can be extruded forming, which can
Biggish shear deformation is provided, it can be achieved that large plastometric set Grain refinement effect achieved, crystal grain are more tiny
Even, the comprehensive mechanical property of obtained board product significantly gets a promotion；
Five, the horizontal die cavity at each position in insert is gradually filled with when forming process convex mould downlink loads after blank compressive deformation.
When punch-pin is sequentially through plate after forming is kept completely separate with blank, cutting action is played.It is surplus
Remaining blank can flow into bottom shape chamber and realize near-net-shape, and stock utilization significantly improves；
Six, compared with traditional plate manufacturing process, this method eliminates a large amount of intermediate treatment process flow, realizes high-performance
A variety of plates batch shapes/becomes second nature integrated short route coordinated regulation and customized, no rebound and setting performance is good, plate
Forming quality is high；
Seven, apparatus structure is simple, process is few, and process is short, at low cost, is easy to producing practice and extension in practice.
