Description
Technical field
The present invention relates to mould manufacture field, and in particular to a kind of failure mould fast repairing method of no archetype.
Background technology
Global industry is fast-developing, and mould accounts for increasingly consequence in industry is manufactured, and aircraft with
Had a wide range of applications in terms of automobile production, in field of industrial production, mould is without interchangeable technological equipment, is to save original
Material and the energy, lifting productivity ratio, improve the excellent mode of mould product economy, it has also become modern production competes to be sent out with industry
An important factor for exhibition；The operational error or fair wear and tear of staff, often causes mould damaged or failure, and some are from foreign countries
The precision die of import, often because not having CAD model and drawing information, mould can only be carried out in burn failure or abrasion
Processing is scrapped, on the one hand seriously reduces the efficiency of production, on the other hand adds the cost of manufacture.
The repair mode of failure mould has laser melting coating reparation, Bead weld repair and argon arc welding reparation at present.
Laser melting coating restorative procedure is to place selected materials in mould invalidation region, by laser by packing material and mould
Matrix surface melt, form metallurgical binding after cooling, although such a restorative procedure causes deflection small on mould, heat input compared with
It is small, but equipment is expensive, repair process is complicated.
Technique for overlaying is to cover one layer or several layers of technique mistakes with relative performance welding material in mould invalidation region heap
Journey.But the mould after Bead weld repair possibly can not meet the requirement of some working conditions.
Argon arc welding reparation is that mold damage is measured using survey tool or worker's estimation mode, then utilizes argon
Arc-welding carries out REPAIR WELDING, then excess stock is machined, grinding process meets production requirement, such a mode cost
Than relatively low, prosthetic appliance is fairly simple, but time-consuming, and the precision of restoring area is difficult to ensure that production requirement.
The content of the invention
It is an object of the invention to provide a kind of failure mould fast repairing method of no archetype, in no original CAD
On the basis of model, it is possible to achieve the accurate control of mould repair thickness and reparation amount, effectively reduce and locate after even removing reparation
Manage link, improve the precision and quality of mould repair, for mould field repair remanufacture a kind of low cost of offer, high accuracy,
Efficient effective way.
The present invention adopts the technical scheme that to solve above-mentioned technical problem：
A kind of failure mould fast repairing method of no archetype, feature have steps of：
Step 1：Die surface is cleaned, surface oil stain, anvil cinder is removed, analyzes damaged die surface failure mode, to losing
Imitate mould surface spraying reflective agent；
Step 2：Failure mould is scanned by digital scanner and obtains cloud data, the point using reverse software to the mould that fails
Cloud data are handled, and draw the CAD model of failure mould；
Step 3：Application software is repaired to the failure site of failure model, the Mould CAD model before being failed, is worked as
Do complete CAD model；
Step 4：By obtained failure Mould CAD model and the complete CAD model obtained, failure portion is obtained with CAD software
The threedimensional model of position；
Step 5：The threedimensional model of obtained failure site is subjected to slicing treatment, welding correlation is determined according to the data of lamella
Technological parameter；
Step 6：Related process parameters setting is carried out by laser welder, realized to area to be repaired successively REPAIR WELDING；
Step 7：To restoring area quality inspection, if meet original mould requirement, if be unsatisfactory for after also needing to progress
Continuous processing, Surface Machining is carried out by numerical control device, hammering eliminates internal stress etc..
Preferably, step 1 due to die surface reflective it is stronger, and have the uneven phenomenon in part, therefore carry out surface
Spray the special developer of scanner；
Preferably, the scanning device described in step 2 is high-precision optical grating projection photo taking type spatial digitizer；
Preferably, the model obtained in step 3 on the basis of archetype is not known by reverse software.
The method have the benefit that：
1. reverse Engineering Technology, welding technique, three-dimensional technology are combined together by the present invention, accomplish to failure mould
Automation repair, digitize, refine feature ensure mould repair quality；
2. the present invention realizes the cloud data from complexity to the reconstruct of accurate failure threedimensional model, improve and obtain CAD model
Efficiency, due to the failure site of only processing mold, the following process avoided, mould repair efficiency is improved, reduces cost；
3. the present invention is to obtain model data using reverse software on the basis of no archetype, avoid does not have in production
During original CAD model, loss that mould is scrapped has very big practical value in production and living.
