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 3-dimensional metal covering and make 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 (integral body) slab 3-dimensional metal covering, and various shapes, overall dimensions are large, and drawing depth is large, adopts the thick metal material manufacturing of 2mm～3mm; Need adjusting just can reach dimensional requirement and the requirement attractive in appearance of product design after adopting the mould manufacturing.In the adjusting process, need adjusting frontier inspection in limit to survey.Large-scale but (integral body) slab 3-dimensional metal covering detection difficult, employing Digital Detecting Method need to be purchased large-scale measurement device and detection time is long, and testing cost is high, detection efficiency is low, is not suitable for limit adjusting frontier inspection and surveys.
Summary of the invention
The purpose of this invention is to provide a kind of large-scale slab 3-dimensional metal covering and make detection method, be fit to limit adjusting frontier inspection and survey use, quick, directly perceived, the easily operation of testing process avoids investment to purchase large-scale measurement device, shortens detection time, reduces testing cost, improves detection efficiency.
For achieving the above object, the invention provides a kind of large-scale slab 3-dimensional metal covering and make detection method, it is characterized in that: the piecemeal manufacturing is welded into integral body again, employing is repaiied type, single-piece deburring based on the single-piece of whole mould to the piecemeal single-piece, the piecemeal single-piece is adopted based on the single-piece detection of whole mould with to the integral body of large-scale slab 3-dimensional metal covering sew up detection.
Segment partition scheme is to determine according to the project organization of large-scale slab covering and pressworking equipment pressure, table top size.
The manufacturing of whole mould is to cast out the detection tire according to part model first, the line of demarcation of then detecting the tire outer surface and marking the piecemeal single-piece according to segment partition scheme.
Detection is to adopt whole mould as testing equipment, with the outer surface of whole mould as examination criteria, piecemeal single-piece inner surface is detected respectively, and the outer surface that large-scale slab 3-dimensional metal covering inner surface is attached to whole mould carries out whole detection, in the gap of large-scale slab 3-dimensional metal covering edge visual inspection mould product and examination criteria and as the standard of next time adjusting; Judge whether large-scale slab 3-dimensional metal covering fits with testing equipment and as the standard of next time adjusting in the inner method of knocking listening that adopts of large-scale slab 3-dimensional metal covering.
The present invention is as follows with respect to advantage and progress that prior art has:
1, reduce cost: avoid the large-scale measurement device of investment buying.
2, be fit to arts demand: can survey use by adjusting frontier inspection in limit.
3, quick, directly perceived, the easily operation of testing process: large-scale slab 3-dimensional metal covering is placed on the testing equipment and can detect; Particularly for the piecemeal single-piece that detects large-scale slab 3-dimensional metal covering, very convenient.
4, shorten detection time, reduce testing cost, improve detection efficiency.
Description of drawings
Accompanying drawing 1 is the structural representation of whole mould of the present invention.
The specific embodiment
With reference to accompanying drawing 1, be illustrated as the whole mould of the three-dimensional headwall steel construction of certain outlet passenger train outer covering piece, detected product is that a length surpasses 4m, and width surpasses 3m, drawing depth surpasses large-scale (integral body) slab 3-dimensional metal covering of 600mm, thickness of slab 2mm; The preparation detection method is as follows:
1, analyzes the project organization of large-scale (integral body) slab 3-dimensional metal covering, according to the existing manufacturing resource capability of manufacturing enterprise, such as small pressure process equipment technical indicator, mould design and manufacture level, in conjunction with later stage assembling, welding manufacture technology scheme, determine rational segment partition scheme;
2, manufacture and design the whole mould with single-piece cut-off rule according to segment partition scheme, provide the piecemeal single-piece to repair type, deburring, detection and whole the stitching and detect the equipment that uses;
3, utilize existing small pressure process equipment, manufacture and design small mould and carry out the piecemeal drawing and moulding;
4, utilizing whole mould to carry out the piecemeal single-piece repaiies type, deburring, detection and carries out each piecemeal single integral piece at whole mould and sew up and detect;
5, judge whether large-scale slab 3-dimensional metal covering fits with whole mould and as the standard of next time adjusting in the inner method of knocking listening that adopts of large-scale slab 3-dimensional metal covering.
