Project of workshop of outfit of car plant solder always contracts should in order to design, make, installation car solder installs technological equipment to have project government for masterstroke. Engineering design stand or fall is the premise condition of project quality stand or fall, also be decision project whether the key of rationalize and economization. Overview our country builds what the project runs system to deepened reform to promote a project to always contract the development in automobile industry, of a lot of car plants build minute of plant or build product line to use a design to purchase construction (EPC) / hand in the key to always contract means. Because the developed country relies on the market to deploy resource effectively, social division of labor is meticulous and reasonable, emphasize specializationed effect. Accordingly, car plant is on enterprise interior organization and personnel configuration, emphasize particularly on to produce a field in the car. Differ with car plant of home, the aspect is built in the factory, the capital construction that domestic factory has standing does wait for similar branch and personnel, and the Motor Corporation of the developed country plans besides the technology that provides a few major outside personnel, work of other and professional technology relies on the force that specializations socially mostly. Domestic joint ventures is general build project cent to be built for earth with public system project (B&U) , equipment and electronic-controlled project (M&E) two parts. Because the car is versed in the factory is in order to make, the project project that installs technological equipment to be dominant, in outfit of punch of plant of car main engine, solder, besmear outfit, general assembly in 4 old technology, only punch and solder install technology, it is the vital technology that affects automobile body precision, the quality demand that fits a project to solder because of this leader plant is very high also. Project project always contracts resource of OK and reasonable configuration, improve level of management of project solid bestow, improve investment benefit, environment benefit and social beneficial result. General component is the construction cycle that builds a project decision-making phase, executive preparation phase, executive phase and phase of complete of put into production. Below only with respect to the project decision-making with executive preparation level is made specific elaborate. The project is decision-making level project is decision-making period one of the most serious job content are project definition and project goal argumentation, complete plan of a construction namely. Inside the working limits that this job does not put in 's charge to always contract in the project commonly. Abroad and joint-stock car company, intellectual property of general and strict esteem and have a technology only. Sometimes the project definition of file of invite public bidding is very simple, have product plan only or build a standard, some has plan of a technological process. Bidder can weave according to his specialty engineering technology plan undertakes bidding. Person of invite public bidding is chosen to bidding engineering technology plan undertakes comparing, make choice of offers first-rate to bid plan person as first supplier. Next owner and first supplier form a group, undertake initial design of combination. After initial design is finished, talk to always contract again contract, if the negotiation is successful, owner and first supplier are signed always contract contract. Car company of home, often let each supplier free make a few plan, they also join a few their opinion in these plan, taking these plan and each to discuss next, choose finally in numerous plan decide a plan, let each bid to allow with this plan, decide the supplier that win the bid again, was equal to total contractor to also share the decision-making stage of the project actually. Always contract decision-making phase should make clear the project the following foundation target. 1.

Quality target: Include to use the requirement of level of function, productivity, technology and item category. Use function namely the utility of the workshop; Productivity is to point to what a particular year of normal production operation after project building can achieve to anticipate productivity. Average productivity is taller, requirement technology level is higher also. In solder outfit workshop can have a view sometimes: Solder dot gets ready automatically rate how much to achieve, can count an index of technical level. Item category is to point to the dimension precision that wants clear white automobile body, control limits, quality of solder dot, welding line asks to wait. 2.

Plan target: Inside time limit of reasonable time limit for a project, set the plan target of each phase, finish the plan that builds a project to plan. 3.

Investment target: Job of the construction that finish, need devoted manpower, financial capacity, material resources. Preliminary put forward to always invest a program, discuss clear investment target, readjust quality target, undertake investing controlling. The project carries out preparative phase project to carry out the main job that plans stage is a project bag of design, cent is purchased and enter the arena executive preparation. Begin to undertake craft is designed above all, decide with owner workshop technology plane arranges a plan, undertake the design of workshop next, in the meantime, earth builds a design to notice the consistency of whole factory and other workshop and harmonious sex even. Should affirm difference in temperature of water of requirement of quantity of dot of water supply of circular cooling water, water supply, water quality, pass in and out asks, the means of circular water tower (open type or shut type) , the requirement such as conduit and valve, begin to be designed to catchment major next, the factory of the joint ventures has fire control gush to drench even mostly systematic requirement. Should affirm winter whether heating, summer uses air conditioning or fan, begin to warm after the requirement such as dust control a professional design. Should affirm reduce dot of airy air feed, air consumption and air feed pressure (it is commonly 0.

6MPa) , reduce airy quality rank; Dot of the air feed pattern that confirms the special gas such as CO2 gas and argon gas, air feed, air consumption and air feed pressure, begin dynamical major to design next. Should affirm factor of capacity of dot of workshop power supply, installation, power and of short duration carry rate, voltage fluctuant requirement, special voltage asks (if sheet of high pressure, dc is not low-pressure three-phase 380V equally,ask) , use insert receive bus or cable power supply, bus height position, be versed in a requirement of intensity of illumination, bigger solder outfit workshop has commonly wait between alone distribution. Between each major in designing a process even each other carries a data, in order to make sure the design is complete and accurate. Nextpage is in technology design, the most important is the design that plane of the technology that finish arranges a plan, among them the key that the stand or fall that solder outfit craft analyses is technology design success or failure, in craft design phase should finish content of the following job: 1.

Technology research, be versed in a solder the dot distributings, watch of metre research, pitch time is made, the amount of solder clamp, of norms preliminary affirm and be versed in a layout research. 2.

According to part of digital-to-analogue, product tree, solder orders graph and metre requirement, the solder that considers automobile body in detail installs technological process, affirm labour digit, work out technological process gets stuck. 3.

Participate in SE(at the same time project) Simultaneo Us Engineering, the key is productivity analysis and exercise sex analysis. 4.

Reasonable and divisional, have big partition to the workshop according to the function first, the demand that spreads according to production, content next position to every area, size undertake cent piece is mixed adjust. 5.

Those who have detailed craft plan is perfect, affirm the detailed coordinate position of equipment, the appearance of equipment and dimension, set the floor by real volume and position ark of of all kinds and electric control, material or blank bin, work or material rest and craft platform, offer final facilities detailed account. 6.

According to craft requirement, the data that at the same time supplier of collect steel structure carries, offer material of steel structure demand. 7.

According to final equipment detailed list, collect puts forward the public bad news such as gas of water and electricity to measure a data. 8.

The equipment foundation data that collect equipment supplier carries, refer equipment foundation to wait special compose data. 9.

According to craft requirement, raise book of clamping apparatus style. 10.

According to craft requirement, undertake to conveyor the concept is refined, raise the style book of conveyor. Plane of good to do technology decorates the design of the graph, mix to crucial level as soon as possible even nonstandard equipment undertakes invite public bidding is purchased distributing a packet, if robot system, production carries system, solder to hold clamping apparatus, door,build the system side the bag, air to purify the system surveys engine system with 3 coordinate, decide a supplier again. After be being undertaken refining design and type selecting by these suppliers next, put forward equipment foundation to wait by the supplier special compose data and public requirement, hand in again have land by structural major and public major construction plan and public system design. Equipment of mark of dispute of another when the project designs main content is designed. Basically include solder to install the design of clamping apparatus and the design that all sorts of workpiece carry equipment, and the design of electric control system. The design of solder outfit clamping apparatus is the key that mark of blame of solder outfit workshop designs, solder outfit clamping apparatus is the key that automobile body precision forms assures an element. Here introduces simply to design circuit. Above all, according to the demand that produces craft and metre, contrast product part tree undertakes digital-to-analogue is analysed, digit of worker worker of preliminary and certain production and every labour spare parts composition and craft content, finish solder flow chart, affirmatory solder holds clamping apparatus detailed account. According to the requirement of fixed position information of the product, the notional sex design of the clamping apparatus that finish reachs book of clamping apparatus style. According to book of clamping apparatus style, undertake detailed clamping apparatus is designed again, complete detailed three-dimensional design above all. If use a robot to solder, undertake the robot solders even imitate. After three-dimensional design is finished, want to undertake designing evaluating, invite owner to attend. According to evaluation opinion, three-dimensional design is revised after finishing, resumptive design of attempt of 2 dimension project. After clamping apparatus design is finished, OK the technological process with final basis, those who have the relevant facility such as welder of welder, column of solder clamp, snail, CO2 welder and gelatinize machine purchase; According to result of solder clamp simulative, after undertaking fine design of solder Qian Xiang by solder clamp supplier, of slippery course of balancer and clamp of the solder that finish, welder solder clamp purchase. To solder outfit workshop always contracts project, ask according to manufacturing technology even, undertake mark is designed manufacturing other blame of the system, other people of system, production accuses to shed system and craft steel structure to wait for a design in including production to carry system, workshop IT system, production. Production carries a system is to point to use all sorts of equipment that be not mark to satisfy workpiece to be versed in in production a transportation between and the transportation that cross a workshop. Although be opposite directly euqally unlike clamping apparatus,these carry a system the quality of automobile body produces an effect, but it is production however whether the assurance of success, it is production whether the assurance that contented metre asks, more whole project whether successful key. Reasonable, active worker worker workpiece is carried, can reduce labor intensity of the worker greatly, improve work efficiency, reduce repair rate, promote a product quality. Because solder installs a workshop to often use intermittent production, and besmear outfit workshop often uses serial production, manufacturing metre is different, because this installs a workshop to install the white automobile body of the workshop to carry a line to besmear from solder, have the function of have a change of luck not only, still should have the function that store, because this is used mostly,accumulate those who put type to carry a line, store the quantity is calculated according to the requirement of balanced production, general not less than solder hold a workshop the crop of half class. Put forward in equipment electronic-controlled after the data, can begin the design of electric control system. The course is produced in car solder deliver a child in, the magnetic field that produces as a result of solder clamp is bigger, solder splatter more, electric design should the requirement of the special environment such as concussion of mature electric current and electromagnetism interference, electric component often is used be able to bear or endure strong magnetic field and sealing are better tall defend the electric component of grade, defend grade is IP54 commonly, assure to control a system soft, hardware runs stability. Enter the arena the preparation that executive preparation includes personnel, want to match personnel of technology of neat of all kinds construction, want to have mount guard card, staff of special type work should have card of special type exercise. Solder of equipment installation phase installs the personnel of special type construction with commonly used workshop to have: Remove driver of heavy industry, forklift, electric welder and electrician. Want to match machines and tools of neat of all kinds construction, if remove the hydraulic pressure that raises 10m to rise,fall car, forklift; Field, viatic prepares, whether to have construction and pile up the field of material, whether to foster cordial relations between states the road of construction car pass in and out; The preparation of construction water and electricity, equipment installation phase wants to decorate few points in workshop interior temporarily dynamical distribution ark, the service radius of every distribution ark should be 60m left and right sides, if build a workshop, consider even sometimes nightly temporarily illume; The preparation of spot office and living facilities. Project ministry should coach cent hires square staff " construction organizes a design " . Ask content is comprehensive and accord with actual, have maneuverability and but inspectability. Project ministry should check cent to wrap square safe precautionary measures mainly whether effective, reach the designated position. Condition of the start working that check, discover a problem to answer responsibility of seasonable and written announcement just asks to correct. After the condition is had, can begin the executive phase of the project. CNC Milling
