Abstract
A process for manufacturing a ship hatch cover of a ten-thousand-tonnage container ship belongs to the shipbuilding field and comprises the following steps of: manufacturing an assembly jig; calibrating the levelness of the assembly jig before building and dividing the assembly jig rationally according to the product; lofting and blanking, detailing shrinkage allowance to each part of the hatch cover, and elaborately setting the shrinkage allowance; fabricating parts: dividing the hatch cover into three major assembly areas, requiring that all structures of the part areas are connected through flat fillet weld or butt weld; assembling the structure of the hatch cover, and then checking and meeting various accuracy requirements; mounting a container foot; performing tracking, supervision and measurement by using QC from container seat marking, before welding of the container seats and after welding of the container seats, repairing the unaccepted container seat immediately, and finally performing a container hoisting test to perfectly guarantee the accuracy of the container foot. With the abovementioned process research and improvement, the production efficiency can be improved to a large extent; and compared with the traditional building way, about 8% of energy can be saved for each set and the building period can be shorted by about three weeks.
Description
Technical field
The present invention relates to ten thousand tons of box ship hatch cover manufacturing process peculiar to vessel, belong to the ship building field.
Background technology
The manufacturing 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; If adopting classical production process makes; Need product be stood up to proofread and correct repeatedly and can reach the design accuracy requirement, so not only wasting manpower and material resources, and production cycle three months nearly; Completion to whole ship makes a big impact, and is a urgent problem at present.
Summary of the invention
The purpose of this invention is to provide a kind of ten thousand tons of box ship hatch cover manufacturing process peculiar to vessel.
The problem that the present invention will solve is that existing ten thousand tons of box ship hatch cover fabrication process cycles peculiar to vessel are long, inefficient deficiency.
For realizing the object of the invention, the technical scheme that the present invention adopts is:
Ten thousand tons of box ship hatch cover manufacturing process peculiar to vessel may further comprise the steps:
A, manufacturing moulding bed; Moulding bed is the basis of hatch board accuracy guarantee; Because the production site settlement of foundation causes moulding bed horizontal plane error big; Before construction, the moulding bed level is proofreaded; Requirement ± 1mm; To guarantee the assembly precision of hatch board, rationally moulding bed is divided based on this product, accomplish the utilization rate maximization;
B, setting-out and blanking; Because this hatch board material therefor all is the following thin plate of 10mm more than 90%; Welding contracted quantity all is difficult to control with distortion; Based on company's working condition and characteristics; Knowhow in conjunction with the past like product; Allowance for shrinkage is refine to each position of hatch board, meticulous allowance for shrinkage is set guarantees the product precision, and enhance productivity;
The making of C, parts; This hatch cover is divided into three big assembling zones, requires all structures of component region all to adopt flush fillet weld or flat butt welding, can reduce the parts distortion like this; And assurance welding quality and moulding; Therefore, as much as possible parts are divided to this zone assembling, with the production cycle of group in shortening and matching area;
The assembling of D, hatch cover structure, base program is: carry out top board submerged arc-welding and distortion correction by flame after hatch cover stands up, adjust four jiaos of levels and be controlled at ± 1mm in; Hatch cover planeness and camber tested carry out coupling work after qualified; Install except annex, also will close and join, make hatch cover reach running condition a minute gap; Guarantee to divide the watertightness performance of gap, check and satisfy each item accuracy requirement;
E, case pin are installed; After accomplishing, the assembling of hatch cover structure carries out the installation of case pin; Before block line, block weldering and the block postwelding all follow the tracks of, supervise, measure with QC; In time undesirable block is reprocessed, adopted the test of freight container box at last, with guard box pin precision in working order.
Advantage of the present invention: through above-mentioned technical study and improvement, radian is enhanced productivity greatly, and more traditional mode of construction is compared, and every cover energy efficient is about 8%, shortens about three week of production cycle.
The specific embodiment
Be further described in the face of the present invention down.
Ten thousand tons of box ship hatch cover manufacturing process peculiar to vessel may further comprise the steps:
A, manufacturing moulding bed; Moulding bed is the basis of hatch board accuracy guarantee; Because the production site settlement of foundation causes moulding bed horizontal plane error big; Before construction, the moulding bed level is proofreaded; Requirement ± 1mm; To guarantee the assembly precision of hatch board, rationally moulding bed is divided based on this product, accomplish the utilization rate maximization;
B, setting-out and blanking; Because this hatch board material therefor all is the following thin plate of 10mm more than 90%; Welding contracted quantity all is difficult to control with distortion; Based on company's working condition and characteristics; Knowhow in conjunction with the past like product; Allowance for shrinkage is refine to each position of hatch board, meticulous allowance for shrinkage is set guarantees the product precision, and enhance productivity;
The making of C, parts; This hatch cover is divided into three big assembling zones, requires all structures of component region all to adopt flush fillet weld or flat butt welding, can reduce the parts distortion like this; And assurance welding quality and moulding; Therefore, as much as possible parts are divided to this zone assembling, with the production cycle of group in shortening and matching area;
The assembling of D, hatch cover structure, base program is: carry out top board submerged arc-welding and distortion correction by flame after hatch cover stands up, adjust four jiaos of levels and be controlled at ± 1mm in; Hatch cover planeness and camber tested carry out coupling work after qualified; Install except annex, also will close and join, make hatch cover reach running condition a minute gap; Guarantee to divide the watertightness performance of gap, check and satisfy each item accuracy requirement;
E, case pin are installed; After accomplishing, the assembling of hatch cover structure carries out the installation of case pin; Before block line, block weldering and the block postwelding all follow the tracks of, supervise, measure with QC; In time undesirable block is reprocessed, adopted the test of freight container box at last, with guard box pin precision in working order.
Company uses through the production technology to this product, can guarantee product design preferably, and shorten production cycle greatly, promotes company's competitiveness.
