Numerical control digital display control device of hydraulic press

Abstract

The invention discloses a numerical control digital display control device of a hydraulic press. The numerical control digital display control device comprises a control device body, a protective frame is arranged at the edge of the control device body, a limiting switch is fixedly installed on the inner surface of one side of the protective frame, first permanent magnet steel blocks are installed on the other side of the protective frame in an embedded mode, light supplementing mechanisms are arranged at the top and the bottom of the protective frame, a dustproof baffle is arranged on one side of the protective frame, an observation window is installed on the dustproof baffle, second permanent magnet steel blocks are installed on one side of the dustproof baffle in an embedded mode, a connecting rod is arranged on one side of the dustproof baffle, a handle block is fixedly connected to one end of the connecting rod, and a hinge is arranged on the other side of the dustproof baffle. The numerical control digital display control device is simple in structure, the dustproof performance of the control device is improved, mistaken touch is effectively avoided, meanwhile, light can be supplemented to a key area of the device, so that the operation safety is improved, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of hydraulic presses, in particular to a numerical control digital display control device for hydraulic presses. Background technique [0002] The basic principle of the hydraulic machine is that the oil pump sends the hydraulic oil to the integrated cartridge valve block, and distributes the hydraulic oil to the upper or lower chamber of the cylinder through each check valve and relief valve, and the cylinder moves under the action of high-pressure oil. , The hydraulic press is a device that uses liquid to transmit pressure. All operations of the hydraulic press are realized through the control device. At the same time, some main parameters during the operation of the hydraulic press will also be displayed on the display screen of the control device. [0003] The control devices in the prior art are directly exposed to the air. During long-term use, not only a large amount of dust will accumulate on the con...

Problems solved by technology

[0003] The control devices in the prior art are directly exposed to the air. During long-term use, not only a large amount of dust will accumulate on the control device, but also accidental touches may occur, which is not conducive to people's safety. Use, secondly, in the case of low light, due to the high brightness of the display screen on the control device, and the operation buttons on the side of the display screen do not have the function of backlight, most of the reflected light will be emitted by the display screen Therefore, the key area will become very blurred, which will affect the normal operation of the staff. Therefore, we propose the numerical control digital display control device of the hydraulic press
