IQR is technology of newest resistance welding control, can soldering in the process monitor automatically solder the voltage of loop and electric current, computation gives resistor and power; And clamp of intermediate frequency solder is had not only assure to solder the quality, characteristic that increases dependability, and apply to a variety of material such as zine plate of high strenth armor plate, plating, stainless steel, aluminium board. The role with the very important person that they are acted in trial-produce workshop. Develop as the high speed of manufacturing industry of our country automobile, the communication that with abroad advanced car design makes and build a car the demand of own brand is increasingly pressing. Of trial-produce workshop build and be being perfected ceaselessly is each cars the Chongzhongzhi that production company works is heavy, accordingly, the pattern that establishs to accord with contemporary car trial-produce as soon as possible is crucial! Trial-produce workshop bear wears what new product research and development and technology of goods lot production ask to make the work, its are main the purpose is to be able to satisfy the solder of white automobile body of all sorts of new development models to hold development work, and be not onefold some kind of model, accordingly, choose equipment to should consider the adaptability of a variety of models. In the meantime, as a result of trial-produce workshop often the space is limited, impossible from deploy a large number of multiform solder clamp at the beginning, the job of clamp of on product line hundreds of solder often can be finished by clamp of a few solder only, accordingly, requirement trial-produce workshop raises the utilization rate of every solder clamp as far as possible. The first time of many solder clamp chooses to answer as far as possible in a popular style, and every should have solder clamp fast outfit orgnaization mixes many to solder the choice function of parameter, in view of this, IQR and technology of vice of intermediate frequency solder appear crucial. IQR technology is soldering in the process, the effect that the quality that solder nods suffers all sorts of elements easily (if pursue 1) . IQR is technology of newest resistance welding control, IQR function is soldering in the process monitor automatically solder the voltage of loop and electric current, calculate a resistor (namely the resistor of loop) with power. Graph 1 influence solders the element of quality if controller did not detect solder diagnostic curve, controller will be adjusted solder electric current or the effect time that extend electric current, let solder diagnostic curve appears, should solder when diagnostic curve is accorded with, solder the process ends. If do not have controller to issue alarm signal, show what every solder nods to solder quality got assuring. Such exterior configuration in weldment, ply and material number of plies change or draw near when solder dot produces billabong, do not require readjust set process. Technology of vice of intermediate frequency solder pursues 2 systems are basic composition and principle are current, a lot of cars that clamp of intermediate frequency solder has been in Europe, United States, Japan produce manufacturer to get use, besides can reduce manufacturing cost, still assure to raised the security of the car and truckload quality to offer. As high strenth armor plate, plating is used increasingly in auto industry zine plate, stainless steel, aluminium board and multilayer board solder and the combination of different material (like aluminium and armor plate) , clamp of intermediate frequency solder also is soldering the body in these material reveals the advantage that cannot replace. Specific for, include the following fields: 1.

Weld time of millisecond class pilot, make solder quality has safeguard more, repeatability is better; 2.

Have the aid of is sub and constant voltaic adjustment, the high quality that realized closed-loop control solders union; 3.

The electrode impress of workpiece surface decreases apparently; 4.

Higher power density shortened weld time; 5.

The monitoring of without reason barrier and record offerred quality to assure to solder; 6.

Lesser equipment power and load of symmetrical electrified wire netting reduced join cost; 7.

Realized low cost through ideal power factor can; 8.

Achieve taller electrode durability through shorter weld time and lesser voltaic bear; 9.

Suit to solder particularly aluminous, stainless steel, coating board and high strenth armor plate; 10.

Can realize the couple that has stuff of function of different heat conduction, be like, aluminium and steel; 11.

As a result of energy fast, concentrated ground is inputted, make work in-house have loss of quantity of heat hardly; 12.

Can cause little damage only to film surface () of the film that be like zinc; 13.

The transformer that becomes light apparently makes its apply at spot welding clamp to become a possibility (about decrescent becomes light 50 ％ ) ; 14.

There is big energy loss in sub loop, ensured consequently bigger solder power output. The new technology application in trial-produce workshop 1.

All of central computer science department uses interconnected system of central computer science department, can let concern personnel of technology of administrator, project to reach each worker worker to each solder clamp state be clear at a glance, the news that knows the site in time, quality that moves product of experience history data, analysis, setting is adjusted solder program. 2.

IQR intelligence solders quality control system uses IQR intelligence to solder quality controls a system, can reduce influencing factor not only, reduced mass checking program, and can rise solder quality. 3.

Clamp of intermediate frequency solder uses pincers of intermediate frequency solder, can increase dependability, assure to solder at the same time quality. 4.

Solder clamp identifies functional solder clamp to identify a function to be able to reduce workload not only, and can simplify operating sequence. 5.

Ark of control of intermediate frequency of ark of intermediate frequency control can use be born formula 1 generation 8 controller and overhead suspension 1 generation 2 controller two kinds of means (if pursue 3, 4) , can join control 2 or 8 solder clamp, tong ram of all solder clamp can be shut at the same time, when soldering solder clamp among them, other solder clamp is chained. Solder clamp is used those who take memory to block WEP2 is muti_function when handle, controller can differentiate each solder clamp, the record shuts the around order of solder clamp, press ordinal release current next, and handlers is not aware of time lag. Should change when solder clamp, controller identifies solder clamp automatically and call solder accordingly program, make the solderer's operation goes easily simply, and IQR intelligence solders quality is self-adjusting the system is compositive inside intermediate frequency transducer. Graph 3 1 is acting 8 controller graph 4 1 are acting 2 controller 6.

Indoor allocation dish of HIP motivation morale and cooling water allocate dish of collect on HIP indoors, after moving effort to pass dry processing among them, the cylinder that carries solder clamp through a proportioning valve goes up, proportioning valve receives controller signal and adjust the pressure in solder clamp cylinder changes. Cooling water is allocating dish on cent is two (means of refrigeration of clamp of double loop solder) . Additional, allocate dish go up to installing cooling water at the same time flowmeter and prevent conduit blowout to interact stop banish a powerful person. 7.

Fast land is fast land (if pursue 5) cent supply end and sink, normally installation allocates indoors dish with solder between Qian Zhi, beyond 2m of clamp leaving solder (also can install the rear in solder clamp) . In the meantime, need to often change in trial-produce workshop solder clamp, because this is fast,land appears very useful. Graph 5 fast land are current, the trial-produce workshop that company of technology of German NIMAK resistance welding has produced manufacturer for a lot of cars has offerred solder clamp to solder system, include German DAIMLER CHRYSLER to run quickly the system of clamp of many 20 solder inside workshop of trial-produce of Germany of company of the system of many 200 solder clamp inside trial-produce workshop, FORD, Changchun one steam - 12 solder of workshop of the system of 11 solder clamp of department of masses product engineering and trial-produce of Shenyang Hua Chen.
