Abstract

The invention belongs to the machining technology and relates to a method for machining split quenched pattern dies. The method is characterized by including steps of modifying multiple dies, machining an integral pattern die according to the modified dies, quenching, cutting the pattern die into halves, and polishing. By the method for machining split quenched pattern dies, defects that connecting burrs, damage and R-angle exist at a profile joint between the die halves of the split pattern die transitionally and parting surface is not flat and the like are reduced, and a method of independently manufacturing and quenching the two die halves of the split pattern die is changed into the technical method of integrally manufacturing, quenching and splitting. Machining accuracy of the die halves of the split pattern die is improved, the problems of many machining links and less proneness to coordination are solved, and forming quality is improved.

Description

A kind of split quenching pattern processing method
Technical field
The invention belongs to the aviation machine process technology, relate to a kind of split quenching pattern processing method.
Background technology
Need use pattern during the sheet metal component moulding, because the particularity of forming part needs the form for the pattern employing split of moulding, the split pattern is made up of left and right half module sometimes, is made up of left, center, right three half modules sometimes sometimes.If forming part is relatively hard materials such as stainless steel, also need to have higher hardness for forming mould, at this moment mould just needs to quench.Owing to be difficult for processing behind the die quenching, so normal processing method is to quench after half module machines again, assembling is delivered for use then.Actual mould after finding to quench deforms and defective such as wedge angle burns blunt or the die joint wedge angle is damaged through regular meeting, has influenced the connection profile quality between each half module, and then has influenced the surface quality of forming part.
Summary of the invention
Goal of the invention: propose the flawless split quenching of sub-model face pattern processing method between a kind of each split half module.
Technical scheme: a kind of split quenching pattern processing method, split quenching pattern processing steps is:
Step 1, change digital-to-analogue: move 0.2mm with the left half module 2 of split pattern 1 is outer to the left, the slit of 0.2mm between left half module 2 and the right half module 3 is filled and led up with entity be gap body 4 then;
Step 2, process whole pattern by change back digital-to-analogue: go up the whole pattern 5 that Digit Control Machine Tool processing is made up of left half module 2, gap body 4, right half module 3;
Step 3, quenching: the whole pattern 5 after will machining is gone into the glowing furnace quenching and is improved hardness;
Step 4, cut apart each half module: go up wire cutting machine tool and cut in the centre position of gap body 4 with molybdenum filament 6, two parts of telling after the cutting are left half module 2 and right half module 3 both;
Step 5, polishing: with the profile polishing of left half module 2 and right half module 3.
Beneficial effect: the present invention has reduced that the transition of profile junction connects stubble, damage is arranged, defectives such as R angle, die joint out-of-flatness are arranged between each half module of split pattern.Each half module that makes the split pattern has been made into the process of whole manufacturing, quenching, split by the independent process of making, quenching separately.Improve the machining accuracy of split pattern half and half mould, solved the problem that the processing technology link is many, be difficult for coordination, improved Forming Quality.
Description of drawings
Fig. 1 is that master of the present invention looks schematic diagram.
Fig. 2 is schematic side view of the present invention.
Fig. 3 is that the master that the present invention changes after the digital-to-analogue looks schematic diagram.
Fig. 4 is the schematic diagram that the present invention relates to pattern line cutting processing.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done to describe in further detail, see also Fig. 1 to Fig. 4.A kind of split quenching pattern processing method, step is:
Step 1, change digital-to-analogue: move 0.2mm with the left half module 2 of split pattern 1 is outer to the left, the slit of 0.2mm between left half module 2 and the right half module 3 is filled and led up with entity be gap body 4 then.
Step 2, process whole pattern by change back digital-to-analogue: go up the whole pattern 5 that Digit Control Machine Tool processing is made up of left half module 2, gap body 4, right half module 3.
Step 3, quenching: the whole pattern 5 after will machining is gone into the glowing furnace quenching and is improved hardness.
Step 4, cut apart each half module: go up wire cutting machine tool and cut in the centre position of gap body 4 with molybdenum filament 6, two parts of telling after the cutting are exactly left half module 2 and right half module 3.
Step 5, polishing: can use after the profile polishing with 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 line cutting, discharging gap is the parameter of 0.01mm, the width of molybdenum filament spark discharge cutting back material removal is 0.18+0.01+0.01=0.2mm as can be known as calculated, so determine that the distance of left half module skew is 0.2mm.The split pattern can reduce distortion to greatest extent by integral body processing back quenching, goes up the wire cutting machine tool cutting then and removes the gap body of 0.2mm, thereby reach the dimensional requirement of design.
1, one split pattern of embodiment is made up of left half module and right half module, and the change digital-to-analogue is moved 0.2mm outward to the left with the left half module of split pattern, the slit of 0.2mm between left half module and the right half module is filled and led up with entity to be the gap body then, becomes new digital-to-analogue.Process the whole pattern of being formed by left half module, gap body, right half module by Digit Control Machine Tool on the material under the whole digital-to-analogue in change back then.After the machine-shaping whole pattern is gone into the glowing furnace quenching and improve hardness.After quenching is finished wire cutting machine tool on the pattern is cut in the position of gap body with molybdenum filament, two parts of telling after the cutting are exactly left half module and right half module.Can use after the profile polishing with left half module and right half module at last.
