TECHNICAL FIELD
[0001] The utility model relates to the field of plate processing, especially to a beam press for preventing plate deformation. BACKGROUND
[0002] In the glasses manufacturing industry, the market share of plastic glasses is increasing, and in the process of pressing the bridge in the processing, the current method is to bend: the rack is provided with a forming workbench, an upper die with high-frequency heating, a lower die, and a power source driving the upper die to move up and down, during forming, the power source drives the upper die to move downward in two stages, including the stage of heating the plastic plate by lowering the upper die and the stage of continuing to lower the upper die to punch the plastic plate, that is, the power source is a double-stroke cylinder. In actual application, the high-frequency heating time is long, it is easy to fire, the bridge is not full, the processing speed is slow and the quality is not high.
[0003] In the prior art, a lower die of plastic is directly heated by high frequency and molded at the same station, so the heating head is made into a convex die, and the contact with the flat plate is insufficient, which affects the heating effect.
[0004] If the heating and molding are carried out in different stations, the working principle of the high-frequency heating equipment is to emit an electromagnetic field when in use, which generates high-frequency oscillation through aluminum alloy or copper die under certain temperature and pressure conditions to bond PVC plastic. A large part of the reason for high-frequency firing is that the center of the plate is suspended when it is heated by high frequency, and the high-frequency conduction is on the top of the plate. When the metal block above the plate is in conduction, the metal block above the plate has more contact parts, sometimes if it is not connected, it will cause multiple conduction, which will cause the other parts of the plate to fire, which will affect the heating effect of the part. The most likely place to fire is the fusion product, the electrodes, and the center of the plate is suspended. When adjusting the flatness and pressing, the die is unevenly stressed, and the high-frequency fusion penetration causes the tight place to fire. In addition, the high-frequency heating of the prior art heats the entire area of the plate, and the force of the entire molding is applied to the plate. Since the plate itself is relatively thin, it is extremely easy to cause distortion. In view of the above problems, a beam press for preventing plate deformation is needed. SUMMARY
