High frequency induction equipment, Qingdao Tianrun high frequency, high frequency induction equipment prices are Tianrun High Frequency Electric Co., Ltd. Qingdao (www.gaozhoubo.com.cn) this year launched a new upgrade, the above picture is only for reference, please call this page or Tel picture on to obtain the latest information, contact: Yan Lidong. Analysis of the stress state analysis showed a high frequency machine stress state, the pressure on the edge of the mold blank value σs ln (r + h) / r. Reached when r / h values ??α1 and yield stress value σs phase and on values. Thus, the blank in the curved section of the tensile resistance is significantly weaker. In contrast effects are caused by hardening due to the bending of these segments, its more hardened flat segment generated quickly. According to r / h value, is one of the dominant factors. Before carrying capacity of the blank segment determines the punch and the die should be a minimum allowable radius Rmin starting from the following conditions, i.e. not in contact with the mold segments into the plastic blank in a stretched state to be subjected to contact pressure disappears. The resulting value Rmin more general curved nearly 50% larger, low carbon steel, Rmin value does not exceed the thickness value of the material. The inclined wall in the test sample limit angle of nearly 45 °, the results of this can be confirmed by a test pressing profiles. High frequency induction heating device power characteristics of high frequency induction equipment, has been using tubes as switching devices. Since the tube life is short, low efficiency (50% -70%) Load stability is poor, intermittent oscillation (voltage source inverter) during light load operation of the inverter output voltage, high frequency high power applications using IGBT semiconductors devices instead of tubes devices is imperative. IGBT semiconductor devices using induction heating device with a high efficiency, simple circuit. Are relatively easy to manufacture and use, the use of high-power IGBT induction heating power of the workpiece with a fast high-frequency induction heating equipment, easy to control, eutrophication less reliable decarbonization process quality. So using IGBT to achieve high power induction heating power is a wise choice. I produced the KS series and KP Series high frequency induction heating control panel has a digital trigger, free testing, pulse distortion low frequency induction equipment use, anti-interference ability, centralized control, fast dynamic response, a variety of state protection instructions.
