The invention belongs to Machining Technology, relate to a kind of split quenching pattern processing method.It is characterized in that: the step of split quenching pattern processing is: change digital-to-analogue, processes overall pattern, quenching, each half module of segmentation, polishing by digital-to-analogue after change.Between each half module that The present invention reduces Split-mould, the transition of profile junction connects stubble, has damage, has R angle, the defects such as die joint out-of-flatness.Each half module of Split-mould is made to have made the process of overall manufacture, quenching, split into by the process of independent manufacture, quenching separately.Improve the machining accuracy of each half module of Split-mould, solve the problem that processing technology link is many, not easily coordinate, improve Forming Quality.

Description

A kind of split quenching pattern processing method

Technical field

The invention belongs to aviation machine process technology, relate to a kind of split quenching pattern processing method.

Background technology

Need when sheet metal component is shaping to use pattern, sometimes due to the particularity of forming part, need the form adopting split for shaping pattern, Split-mould is made up of left and right half module sometimes, is sometimes made up of left, center, right three half module.If forming part is the relatively hard materials such as stainless steel, also need to have higher hardness for shaping mould, at this moment mould just needs quenching.Owing to not easily processing after die quenching, so normal processing method is quenched after half module machines again, then assembling is delivered for use.The defects such as the mould after actual discovery quenching often can deform and wedge angle burning is blunt or die joint wedge angle is damaged, have impact on the connection profile quality between each half module, and then have impact on the surface quality of forming part.

Summary of the invention

Goal of the invention: propose the flawless split quenching of parting profile between a kind of each split half module pattern processing method.

Technical scheme: a kind of split quenching pattern processing method, the step of split quenching pattern processing is:

Step one, change digital-to-analogue: move 0.2mm by outer to the left for the left half module 2 of Split-mould 1, then the gap entity of 0.2mm between left half module 2 and right half module 3 is filled and led up as clearance body 4;

Step 2, process overall pattern by digital-to-analogue after change: upper Digit Control Machine Tool processes the overall pattern 5 be made up of left half module 2, clearance body 4, right half module 3;

Step 3, quenching: the overall pattern 5 after machining is entered glowing furnace quenching raising hardness;

Step 4, split each half module: upper wire cutting machine tool molybdenum filament 6 cuts in the centre position of clearance body 4, and the two parts separated after cutting are left half module 2 and right half module 3 both;

Step 5, polishing: by the profile polishing of left half module 2 and right half module 3.

Beneficial effect: between each half module that The present invention reduces Split-mould, the transition of profile junction connects stubble, has damage, has R angle, the defects such as die joint out-of-flatness.Each half module of Split-mould is made to have made the process of overall manufacture, quenching, split into by the process of independent manufacture, quenching separately.Improve the machining accuracy of each half module of Split-mould, solve the problem that processing technology link is many, not easily coordinate, improve Forming Quality.

Detailed description of the invention

Below in conjunction with accompanying drawing, the present invention is described in further detail, refers to Fig. 1 to Fig. 4.A kind of split quenching pattern processing method, step is:

Step one, change digital-to-analogue: move 0.2mm by outer to the left for the left half module 2 of Split-mould 1, then the gap entity of 0.2mm between left half module 2 and right half module 3 is filled and led up as clearance body 4.

Step 2, process overall pattern by digital-to-analogue after change: upper Digit Control Machine Tool processes the overall pattern 5 be made up of left half module 2, clearance body 4, right half module 3.

Step 3, quenching: the overall pattern 5 after machining is entered glowing furnace quenching raising hardness.

Step 4, split each half module: upper wire cutting machine tool molybdenum filament 6 cuts in the centre position of clearance body 4, and the two parts separated after cutting are exactly left half module 2 and right half module 3.

Step 5, polishing: can employ after the profile polishing of left half module 2 and right half module 3.

Operation principle of the present invention is: the present invention is 0.18mm according to the molybdenum filament diameter of molybdenum filament Linear cut, discharging gap is the parameter of 0.01mm, the width that after known molybdenum wire spark electric discharge cutting, material is removed as calculated is 0.18+0.01+0.01=0.2mm, so determine that the distance that left half module offsets is 0.2mm.Split-mould can reduce distortion to greatest extent by quenching after overall processing, then goes up the clearance body that 0.2mm is removed in wire cutting machine tool cutting, thus reaches the dimensional requirement of design.

Embodiment 1, a Split-mould is made up of left half module and right half module, and change digital-to-analogue moves 0.2mm by outer to the left for the left half module of Split-mould, then fills and leads up the gap entity of 0.2mm between left half module and right half module into clearance body, becomes new digital-to-analogue.Then process by Digit Control Machine Tool on material under overall digital-to-analogue after change the overall pattern be made up of left half module, clearance body, right half module.After machine-shaping, overall pattern is entered glowing furnace quenching and improve hardness.Cut in the position of clearance body by wire cutting machine tool molybdenum filament on pattern after having quenched, the two parts separated after cutting are exactly left half module and right half module.Finally can employ after the profile polishing of left half module and right half module.
