Embodiment Construction

[0013] The present invention will be further described below in conjunction with drawings and embodiments.

[0014] Such as figure 1 , the control system is connected with industrial computer and PLC, and Taiwan Advantech industrial computer is selected. In addition to the conventional configuration of general computer, this industrial computer is also equipped with digital input IV output module, analog input / output module, counter card, etc., mainly It is used to complete sensor data acquisition, display, storage and control of proportional pumps and proportional valves. The PIE uses the MEISEC-Q series PLC produced by Mitsubishi, Japan. This PIE adopts a modular structure and consists of five modules: a power supply module, a CPU module, an input module, an output module, and a serial communication module. It is mainly used to control various electromagnetic valve action. Serial communication is adopted between the industrial computer and the PLC. This control mode can no...

Abstract

The invention discloses an intelligent loading hydraulic machine control system, and the system is connected with a PLC through an industrial personal computer. The industrial personal computer is selected from Advantech Co., Ltd (China). The industrial personal computer is also provided with a digital input / output module, an analog input / output module and a counter card besides the common configuration of a computer. The industrial personal computer is mainly used for completing the data collection, display and storage of sensors and the control of a proportioning pump and a proportioning valve. The system can timely and accurately control the hydraulic cushion force, and achieves the sheet forming under the blank holder force. Meanwhile, a good graphical interface brings great convenience to the modification of operation and pressing parameters, such as pressure and speed.

Description

Technical field [0001] The invention relates to an intelligent loading hydraulic press control system, which is suitable for the mechanical field. Background technique [0002] The quality of general stamping parts is affected by many factors including part geometry, material, lubrication and so on. The success of part stamping mainly depends on the flow mode of the material during the stamping process, and the blank holder force is an important parameter to control the flow of material. If the blank-holding force is too small, the flow of the material cannot be effectively controlled, and the sheet is easy to wrinkle; if the blank-holding force is too large, although wrinkling can be avoided, the tendency of tearing will increase significantly, and the surface of the mold and the sheet will be damaged. The possibility also increases, affecting the life of the mold and the quality of the sheet. A notable feature of this hydraulic press is that hydraulic pads with 12 specia...
