Abstract
A kind of high duty metal flat board connection dimension accuracy control method, sheet stock is carried out stress-removal process, metal plate is laid on the workbench of level, by the way of using and repeatedly constantly metal plate being rolled, the internal stress of metal plate is discharged；Dimensioned is carried out by mach mode, avoid the impact on metal plate surface quality of heat that metal plate flame cutting produces, during machining, metal plate is placed horizontally in and operates the most simultaneously, during raw material metal panel size manufacturing procedure, carry out weld gap according to test data in advance and weld shrinkage is reserved.The present invention can reach and makes raw material metal flat board eliminate internal stress, it is to avoid raw material metal flat board in subsequent process due to the release of internal stress, and the beneficial effect being deformed in the splicing to metal plate.
Description
Technical field
The invention belongs to metal foil connection dimension Accuracy Control field, particularly relate to a kind of high duty metal flat board
Connection dimension accuracy control method.
Background technology
Ocean engineering be correlated with construction project can run in building course metal plate splicing operation, to spliced
The welding contracted quantity of flat board and the requirement of surface smoothness are higher, and particularly high duty metal steel plate is in flat board docking operation
Higher to the planarity requirements of steel plate, steel plate there will be welding in welding process and shrinks the dimensional accuracy meeting to steel plate splicing
Have large effect, for ensure high duty metal flat board ensures after dock splicing flat-plate molded after dimensional accuracy proposition
The technical method of a kind of high duty metal steel plate connection dimension precision controlling is to ensure the quality of metal plate docking.
For realizing high duty metal steel plate connection dimension precision, by list of references and to high duty metal flat board pretreatment
And the test that welding is to metal plate splicing, summary high duty metal steel plate connection dimension Accuracy Control method:
What the quality problems produced in high duty metal flat board docking operation mainly produced main reason is that:
1) size distortion of the internal stress influence metal plate of steel plate self；
2) heat of plate size cutting and welding affects the size distortion of metal plate；
3) the welding effect of contraction whole metal plate splicing side dimensional accuracy that steel plate produces in welding process.
Summary of the invention
The present invention provides a kind of high duty metal flat board connection dimension accuracy control method, can reach and makes raw material metal put down
Plate eliminates internal stress, it is to avoid raw material metal flat board in subsequent process due to the release of internal stress, and to metal plate
The beneficial effect being deformed in splicing.
Technical problem solved by the invention realizes by the following technical solutions: the present invention provides a kind of high duty metal
Flat board connection dimension accuracy control method, comprises the following steps:
Sheet stock is carried out stress-removal process, metal plate is laid on the workbench of level, anti-by using
The internal stress of metal plate is discharged by the multiple mode constantly rolled metal plate；
Dimensioned is carried out, it is to avoid the heat that metal plate flame cutting produces is to metal plate table by mach mode
The impact of face quality.
Particularly, during machining, metal plate is placed horizontally in and operates the most simultaneously.
Particularly, during raw material metal panel size manufacturing procedure, weld gap is carried out according to test data in advance
And weld shrinkage reserves.
The invention have the benefit that
The present invention make raw material metal flat board eliminate internal stress, it is to avoid raw material metal flat board in subsequent process due to interior
The release of stress, and be deformed in the splicing to metal plate.
Detailed description of the invention
Hereinafter the present invention is described further:
Embodiment:
Owing to there is internal stress inside steel plate, in each process of metal plate splicing, how can produce internal stress
Release thus affect the flatness of steel plate, the quality problems such as overall dimensions, so needing to carry out sheet stock at stress-removal
Reason, by metal plate is laid on the workbench of level use repeatedly constantly metal plate is rolled by the way of protecting
On the premise of card raw material metal flat board quality, the internal stress to metal plate discharges, it is ensured that entering smoothly of subsequent handling
OK.
The cutting of raw material high duty metal panel size is forbidden using flame cutting molding, adopts when metal plate is purchased
Purchasing the steel plate of corresponding size, it is to avoid the secondary operations of steel plate, the original size such as former material metal plate can not meet dimensional requirement
Mach mode need to be used to carry out dimensioned, metal plate can be placed horizontally in and process the most simultaneously, improve machine
The efficiency of processing, uses mach mode it can be avoided that the heat of metal plate flame cutting generation is to metal plate surface matter
The impact of amount.
Because of metal plate, that metal plate splices after having spliced the requirement of overall dimensions is higher, particularly at gold
Genus flat board is specified the when of having the positioner such as perforate, fixture on position, needs to weld before metal plate splices
Connect the overall dimensional accuracy that after avoiding having spliced, its welding impact has been spliced rear metal plate because of metal plate
Require and perforate and the dimensional accuracy of keeper, by the lot of experiments of specific high duty metal plate welding amount of contraction is studied
Welded gaps and welding contracted quantity that grasp metal plate needs in docking operation obtain data accurately, at raw material metal
Carry out weld gap according to test data in advance during panel size manufacturing procedure and weld shrinkage is reserved, at flat board
Splicing process use unified welding procedure to ensure metal plate overall dimensional accuracy after having spliced.
Above by embodiment, the present invention is described in detail, but described content has been only the preferable enforcement of the present invention
Example, it is impossible to be considered the practical range for limiting the present invention.All technical solutions according to the invention that utilize, or the skill of this area
Art personnel, under the inspiration of technical solution of the present invention, design similar technical scheme and reach above-mentioned technique effect, or
Impartial change and the improvement etc. being made application range, all should still belong within the patent of the present invention contains protection domain.
