Analysis of the stress state analysis shows that the stress state high-frequency machine high frequency heat sealing machine prices, pressure on the value of the rough edges of the mold σs ln (r + h) / r. Reached when the r / h value α1 and yield stress σs phase and on values. Thus the supply of high frequency heat sealing machine, rough stretch resistance in the curved section significantly weaker. Instead hardening effects are due to bending caused these segments, its more hardened flat segment generated quickly. According to r / h value, is one of the dominant factors. Before carrying capacity determination section blank punch and die of the minimum allowable radius Rmin should proceed from the following conditions, i.e. not in contact with the mold segments into the plastic blank in a stretched state is subjected to contact pressure should disappear. The resulting value Rmin than the average of nearly 50% larger bending frequency heat sealing machine, low carbon steel, Rmin value does not exceed the value of the material thickness. The inclined wall in the test sample limit angle of nearly 45 °, the results of this can be confirmed by test pressing profiles. Heating layer depth selection and the workpiece related to the power supply requirements. Deep layer of the workpiece heating, use a lower current frequency power supply; heating layer shallow parts, you should use a higher frequency of the current power supply. Select another power supply device power conditions. Heating surface area increases, the need for electrical power increased accordingly. When the heating surface area is too large, or when the power shortage, the continuous heating method can be high frequency heat sealing machine, so that the relative movement of the workpiece and the sensor, heated front, rear cooling. But the best time of the entire heating surface heating. So you can make use of waste heat core part of the workpiece surface hardened and tempered, so to simplify the process, but also save energy. Conventional converter transformer at high frequencies, which have localized hot spots in central core. Therefore, in order to reduce thermal effects, when the conventional converter transformer operating frequency increases, it is necessary to correspondingly reduce the magnetic flux density, increasing its volume. This makes it impossible to use it to do high power density power.
