Description
Technical field
The present invention relates to a kind of job operation of Medical rack.
Background technology
Along with the fast development of material science and super micro-processing technology, Medical rack material category gets more and more, and compares the nonmetallic materials such as metal materials such as common are Stainless steel 316 L, Nitinol, cobalt-base alloys, pure iron, magnesium alloy, and macromolecule.The generation of blocking and causing various sufferer is even caused to stop vessel retraction because Medical rack plays hemangiectasis wall in the blood vessel, requiring on support on each muscle feature structural dimension parameter one to show keeps tension force on whole support each point identical, and this proposes requirements at the higher level to Medical rack processing technology.General Medical rack all adopts seamless tubular goods to process, because insertion type operation is not comprehensive in global evolution, medical material technical development is also unbalanced, at present in the world to the technical standard that the tubing being used as Medical rack is comparatively ununified, and generally specified according to correlation experience oneself by Medical rack research institution or support manufacturer, Medical rack tubing provider provides respective holder according to these regulations.Consider that Medical rack seamless tubular goods adopts the technological method for processing such as drawing to produce, because the defect of technique must be difficult to ensure caliber tolerance homogeneity on whole (general length can more than 2 meters) support tubing.And the support tubing caliber tolerance entirety of giving Medical rack manufacturer needs to control within the scope of ± 10um, in fact due to processing and context of detection technical deficiency, inevitably even overproof problem is changed greatly at the difference place caliber of whole support tubing.
This same support tubing there is the even overproof problem of caliber change, if do not processed in detection and process, the wide consistance tolerance of cut after-poppet muscle will be caused unstable, cause strengthening stent size precision controlling difficulty in support production, produced support even can be made to be difficult to meet the requirement of insertion type operation to support product dimensional accuracy, to cause support to scrap or insertion type operative failure etc.
In conventional medical support production run, also cannot change on support tubing caliber the impact brought effectively to process, only by carrying out complete detection to stent size precision after cut, once find overproof or close to tolerance limits line situation, just judge that this support is as unacceptable product, as long as support there is a dimension overproof, capital causes whole support to be scrapped, just because of this, the qualification rate difficulty after support cut has internal to improve, and causes very big cost pressure and the wasting of resources.
In order to solve this bottleneck, the present invention discloses a kind of support job operation of auto-compensation support caliber tolerance variation, the method processes stand tube material caliber by on-line checkingi, and the data processing centre (DPC) in real time detection gained caliber data are sent to by Ethernet in control system, measured support tubing caliber tolerance variation value will be compensated to next section by data processing centre (DPC) immediately to be needed in the graphic file of cutting, when upper once cutting pattern file, system can be cut according to the new graphic file after compensation automatically like this, thus eliminate because caliber tolerance variation brings the harmful effect caused stent size precision.
