Abstract
Ten thousand tons of box ship hatch cover manufacturing process peculiar to vessel, belong to ship building field, comprise the following steps: manufacture moulding bed, proofread, rationally divide moulding bed according to this product before construction to moulding bed level; Setting-out and blanking, allowance for shrinkage is refine to each position of hatch cover, meticulous arranges allowance for shrinkage; The making of parts, is divided into three by this hatch cover and assembles region greatly, requires that all structures in component region all adopt flush fillet weld or flat butt welding; Hatch cover structure is assembled, and checks and meets every accuracy requirement; Case pin is installed, before block line, block weldering and block postwelding all carry out following the tracks of with QC, supervise, measure, in time undesirable block is reprocessed, finally adopts the test of freight container box, with intact guard box pin precision.By above-mentioned technical study and improvement, can enhance productivity by radian greatly, comparatively traditional construction mode is compared, and often overlaps energy efficient about 8%, about three week of shortening production cycle.
Description
Technical field
The present invention relates to ten thousand tons of box ship hatch cover manufacturing process peculiar to vessel, belong to ship building field.
Background technology
The manufacture of ten thousand tons of box ship hatch covers peculiar to vessel, this product structure is complicated, and the accuracy requirement of freight container block is high; Outside plate is thin, and distortion is difficult to control; Make according to classical production process, product need be stood up repeatedly and carry out correction and can reach design accuracy requirement, so not only wasting manpower and material resources, and nearly three months production cycle, making a big impact to the completion of whole ship, is a urgent problem at present.
Summary of the invention
The object of this invention is to provide a kind of ten thousand tons of box ship hatch cover manufacturing process peculiar to vessel.
The problem to be solved in the present invention is that existing ten thousand tons of box ship hatch cover peculiar to vessel fabrication process cycles are long, inefficient deficiency.
For realizing object of the present invention, the technical solution used in the present invention is:
Ten thousand tons of box ship hatch cover manufacturing process peculiar to vessel, comprise the following steps:
A, manufacture moulding bed, moulding bed is the basis of hatch cover accuracy guarantee, because production site settlement of ground causes moulding bed level error large, before construction, moulding bed level is proofreaded, requirement ± 1mm, to ensure the assembly precision of hatch cover, rationally moulding bed is divided according to this product, accomplish that degree of utilization maximizes;
B, setting-out and blanking, due to the thin plate that this hatch cover material therefor more than 90% is all below 10mm, welding contracted quantity and distortion are all difficult to control, according to company's working condition and feature, in conjunction with the knowhow of past like product, allowance for shrinkage is refine to each position of hatch cover, meticulous allowance for shrinkage is set can ensures Product Precision, and enhance productivity;
The making of C, parts, this hatch cover is divided into three and assembles region greatly, require that all structures in component region all adopt flush fillet weld or flat butt welding, parts distortion can be reduced like this, and ensure welding quality and shaping, therefore, as much as possible parts are divided to the assembling of this region, with the production cycle of group in shortening and matching area;
D, hatch cover structure are assembled, base program is: carry out top board submerged arc-welding and distortion correction by flame after hatch cover stands up, adjustment corner level also controls in ± 1mm, to hatch cover planeness and camber test qualified after carry out coupling work, except annex is installed, also to carry out conjunction to a point gap and join, make hatch cover reach using state, to ensure the watertightness performance of point gap, check and meet every accuracy requirement;
E, case pin are installed, hatch cover structure carries out the installation of case pin after having assembled, before block line, block weldering and block postwelding all carry out following the tracks of with QC, supervise, measure, in time undesirable block is reprocessed, finally adopt the test of freight container box, with intact guard box pin precision.
Advantage of the present invention: by above-mentioned technical study and improvement, can enhance productivity by radian greatly, comparatively traditional construction mode is compared, and often overlaps energy efficient about 8%, about three week of shortening production cycle.
Detailed description of the invention
The present invention is further illustrated below.
Ten thousand tons of box ship hatch cover manufacturing process peculiar to vessel, comprise the following steps:
A, manufacture moulding bed, moulding bed is the basis of hatch cover accuracy guarantee, because production site settlement of ground causes moulding bed level error large, before construction, moulding bed level is proofreaded, requirement ± 1mm, to ensure the assembly precision of hatch cover, rationally moulding bed is divided according to this product, accomplish that degree of utilization maximizes;
B, setting-out and blanking, due to the thin plate that this hatch cover material therefor more than 90% is all below 10mm, welding contracted quantity and distortion are all difficult to control, according to company's working condition and feature, in conjunction with the knowhow of past like product, allowance for shrinkage is refine to each position of hatch cover, meticulous allowance for shrinkage is set can ensures Product Precision, and enhance productivity;
The making of C, parts, this hatch cover is divided into three and assembles region greatly, require that all structures in component region all adopt flush fillet weld or flat butt welding, parts distortion can be reduced like this, and ensure welding quality and shaping, therefore, as much as possible parts are divided to the assembling of this region, with the production cycle of group in shortening and matching area;
D, hatch cover structure are assembled, base program is: carry out top board submerged arc-welding and distortion correction by flame after hatch cover stands up, adjustment corner level also controls in ± 1mm, to hatch cover planeness and camber test qualified after carry out coupling work, except annex is installed, also to carry out conjunction to a point gap and join, make hatch cover reach using state, to ensure the watertightness performance of point gap, check and meet every accuracy requirement;
E, case pin are installed, hatch cover structure carries out the installation of case pin after having assembled, before block line, block weldering and block postwelding all carry out following the tracks of with QC, supervise, measure, in time undesirable block is reprocessed, finally adopt the test of freight container box, with intact guard box pin precision.
Company by apply the production technology of this product, can ensure product design preferably, and shortening production cycle greatly, lifting company competitiveness.
