Abstract
The invention provides a manufacturing and detection method for a large slab three-dimensional metal cover part. The method is characterized in that blocks are individually manufactured and then welded into a whole, single piece shaping and single piece trimming based on an integral die are carried out on each single piece of the blocks, and single piece detection and integral seaming based on the integral die are used for each single piece of the blocks. The invention has the following advantages compared to the prior art: investment is reduced since investment on purchase of large measuring equipment is avoided; the method meets the process need of simultaneous trimming and detection; detection process is fast and visual and is easy to operate since one only needs to put a large slab three-dimensional metal cover part on large detection equipment for detection; the method is especially convenient for detection of single pieces of the blocks of the large slab three-dimensional metal cover part; detection time is shortened, detection cost is reduced, and detection efficiency is improved.
Description
Technical field
The present invention relates to a kind of large-scale slab three-dimensional metal cover part and manufacture detection method.
Background technology
The outer covering piece of the three-dimensional headwall steel construction of passenger train and streamlined front end steel construction is large-scale (entirety) slab three-dimensional metal cover part, and various shapes, overall dimensions are large, and drawing depth is large, adopt the metal material manufacture that 2mm ~ 3mm is thick; Need adjusting just can reach dimensional requirement and the aesthetic of product design after adopting Making mold.In adjusting process, need adjusting frontier inspection in limit to survey.Large-scale but (entirety) slab three-dimensional metal cover part detection difficult, adopt Digital Detecting Method need buying bulky measurement equipment and also detection time long, testing cost is high, detection efficiency is low, be not suitable for limit adjusting frontier inspection survey.
Summary of the invention
The object of this invention is to provide a kind of large-scale slab three-dimensional metal cover part and manufacture detection method, be applicable to limit adjusting frontier inspection and survey use, testing process operates fast, intuitively, easily, avoids investment buying bulky measurement equipment, shortens detection time, reduces testing cost, improves detection efficiency.
For achieving the above object, the invention provides a kind of large-scale slab three-dimensional metal cover part and manufacture detection method, it is characterized in that: piecemeal manufacture is welded into entirety again, piecemeal single-piece is adopted and repaiies type, single-piece deburring based on the single-piece of overall mould, piecemeal single-piece is adopted the single-piece based on overall mould to detect and sewed up the entirety of large-scale slab three-dimensional metal cover part and detects.
Segment partition scheme determines according to the project organization of large-scale slab covering and pressworking equipment pressure, table top size.
The manufacture of overall mould first casts out detection tire according to part model, then marks the line of demarcation of piecemeal single-piece at detection tire outer surface according to segment partition scheme.
Detection adopts overall mould as testing equipment, using the outer surface of overall mould as examination criteria, piecemeal single-piece inner surface is detected respectively, and the outer surface that large-scale slab three-dimensional metal cover part inner surface is attached to overall mould carries out whole detection, in the gap of large-scale slab three-dimensional metal cover part edge visual inspection mould product and examination criteria and as on the standard of once adjusting; Large-scale slab three-dimensional metal cover part inside adopt the method for knocking listening judge large-scale slab three-dimensional metal cover part whether fit with testing equipment also as on the standard of once adjusting.
The advantage that the present invention has relative to prior art is as follows with progress:
1, investment is reduced: avoid investment buying bulky measurement equipment.
2, technique needs are applicable to: use can be surveyed by adjusting frontier inspection in limit.
3, testing process operates fast, intuitively, easily: large-scale slab three-dimensional metal cover part be placed on testing equipment and can detect; Particularly for the piecemeal single-piece detecting large-scale slab three-dimensional metal cover part, very convenient.
4, shorten detection time, reduce testing cost, improve detection efficiency.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of overall mould of the present invention.
Detailed description of the invention
With reference to accompanying drawing 1, be illustrated as the overall mould of certain outlet passenger train three-dimensional headwall steel construction outer covering piece, detected product be a length more than 4m, width is more than 3m, drawing depth more than large-scale (entirety) slab three-dimensional metal cover part of 600mm, thickness of slab 2mm; Preparation detection method is as follows:
1, the project organization of large-scale (entirety) slab three-dimensional metal cover part is analyzed, according to the existing manufacturing resource capability of manufacturing enterprise, as small pressure process equipment technical indicator, mould design and manufacture level, in conjunction with later stage assembling, welding manufacture process program, determine rational segment partition scheme;
2, manufacture and design the overall mould with single-piece cut-off rule according to segment partition scheme, provide piecemeal single-piece to repair type, deburring, detection and the overall equipment sewed up detection and use;
3, utilize existing small pressure process equipment, manufacture and design small mould and carry out piecemeal drawing and moulding;
4, utilize overall mould carry out piecemeal single-piece repair type, deburring, detection and carry out on overall mould each piecemeal single integral piece sew up detect;
5, large-scale slab three-dimensional metal cover part inside adopt the method for knocking listening judge large-scale slab three-dimensional metal cover part whether fit with overall mould also as on the standard of once adjusting.
