Abstract
The utility model discloses an electronic die height display device applied in a press machine, which includes a press slide, a device of adjusting the press slide matched with the press slide of the press machine, a rotary encoder installed in one output end of the device of adjusting the press slide, and the output end of the rotary encoder is connected with a liquid crystal die height display device installed in an electrical box. The electronic die height display device adopts the liquid crystal display device, and can read the relevant information by the rotary encoder installed in the device of adjusting the press slide instead of being fixed on the adjustment device of the press machine. In addition, a control circuit in the liquid crystal die height display device can control the backlight driver circuit, the brightness of the backlight is effectively improved and the stereoscopic display effect of the liquid crystal die height display device is improved.
Description
Technical field
The present invention relates to a kind of high display device of electronics mould for pressing machine.
Background technology
The adjusting device of general pressing machine all adopt the high display of mechanical model read mode transfer numeral number, and the high display of mechanical model must be arranged on the adjusting device of pressing machine, in large pressing machine, because the contour structures of pressing machine is all taller and bigger, be difficult to see clearly the numeral showing on the high display of mould that is placed on pressing machine top.In addition, the display effect of the high display of mechanical mould is bad, and display brightness is low, can not clearly see the information such as the numeral reading clearly.
Summary of the invention
The defect that the present invention seeks to exist for prior art provides a kind of high display device of electronics mould for pressing machine.
The present invention for achieving the above object, adopt following technical scheme: a kind of high display device of electronics mould for pressing machine, comprise press ram, the press ram adjusting device matching with press ram, it is characterized in that, the output terminal of described press ram adjusting device is provided with rotary encoder, and the output terminal of described rotary encoder is connected with the high display device of liquid crystal mould being arranged in electric box.
Further, the high display device of described liquid crystal mould comprises display module and drive circuit module, and described display module comprises backlight, liquid crystal panel and controlled light valve; Described drive circuit module comprises backlight drive circuit, light valve drive circuit and control circuit, and described backlight drive circuit is used to described backlight to provide voltage to drive it luminous; Described light valve drive circuit for controlling described controlled light valve so that the high display device of described liquid crystal mould is switched to corresponding show state under the effect of show state switching signal; Described control circuit is used for receiving described show state switching signal, and according to described show state switching signal, controls described backlight drive circuit to adjust the brightness of described backlight.
Beneficial effect of the present invention: the high display device of electronics mould of the present invention adopts liquid crystal indicator, does not need to be fixed on the adjusting device of pressing machine, and it directly just can read relevant information by the rotary encoder being arranged on slide block adjusting device.In addition, the control circuit controlling back light source driving circuit in the high display device of liquid crystal mould, effectively raises the brightness of backlight, has improved the stereo display effect of the high display device of liquid crystal mould.
