Current, the response that production of the car on international uses quenchs equipment sex of progressively Xiang Rou changes degree to develop. General quench the machine tool is more general, the function is more perfect. The EFD product application that has AEG of representative Japanese DKK, Spain GH, Germany, transnational corporation is very wide. Their common characteristic is, the different spare parts that quenchs in machine tool mouth can ask to different function undertakes the induction heats quench, same even part is multistage change work gear shift also can be achieved; Use the computer to control technical monitoring to show quench process and craft parameter, dog to machine a process entirely, application of numerical control technology is very active mature with each passing day; Computer control makes control main trend, advocate drive uses communication servo electric machinery to procrastinate move, floating rate stabilizes even, fixed position accurate, repeat precision tall; The spare parts rotates use frequency control, can get used to requirement of many sided craft; The advanced technique such as the ball guide screw that represents mechanical drive technology and linear slideway is used in great quantities; The power source that form a complete set becomes dragon, quench the induction of machine tool, cooling system heats quench device already common occurance. Since be put outside reform, although company of one steam group introduced much stage induction to quench equipment, but the PLC pilot that the current test equipment with the most application in car production still is low administrative levels quenchs machine tool. Low, function differs its efficiency, assure to quench hard quality. To make sure the car is new the product develops plan, make up for general quench machine tool function is not worth, on the foundation of advanced technique of digestive understanding abroad, through two years tackle key problem assiduously, what group company uses numerical control and energy control technology to development succeeds and apply at production directly is general muti_function horizontal numerical control quenchs machine tool, banner, function nears specifications home 20 centuries evening recommends the level that do not have equipment from GH company. Half an year moves more make clear, function stability, quality is reliable.

Energy controls principle basis data, change when voltage 5 ％ of ± , power is inside the limits of 10 ％ of ± fluctuant. The relation of D of hard layer of the energy Pt that work place obtains and temper by dipping in water is shown 3 times like the graph. Graph the relation of D of hard layer of the energy Pt that 3 work place obtains and temper by dipping in water from the graph 3 knowable: Power P is in the S when 10 ％ of ± change is dinky part approximate at linear. If add heat energy to measure control to be inside certain limits, so the change of hard layer of temper by dipping in water also is minimum. Same, the area that wants Pg of Pg ± △ and Tg of Tg ± △ to form only is ample small, so, the area of Tg of Tg ± △ and Wg of Wg ± △ also is met enough small (see a picture 4 with graph 5) . This also can get test and verify from several credit analyse. Because of Pg=f(tg) , the function relation of Wg=f(tg) is one to one correspondence. Workpiece heats in the process, when because some is planted,reason instantaneous power greatens, heat according to some rule time decreases; Conversely, lengthen asks when. In controlling a system accumulative total near energy integral is worth control to be inside EFGH deviation belt, achieved the goal that controls energy. Of course, to differring workpiece can install different deviation belt, or same work asks to also can install different deviation to take according to different quality, that is to say, the deviation band of the setting is smaller, acquisition product quality is higher. Curve of change of graph 4 Pg=f(tg) notes: Pg -- instantaneous power did not decide a value, KW; Pg of Pg ± △ -- belt of deviation of instantaneous power change, KWtg -- heat time did not decide a value, s; Tg of Tg ± △ -- heat belt of time set deviation, s. Curve of change of graph 5 Wg=f(tg) notes: Wg -- energy set value, KW.

S; Wg=f(tg) -- belt of energy set deviation, KW.
