Problems solved by technology

However, the control system of the existing large-scale die forging press cannot properly compensate during the low-speed forging process, that is, frequently adjusts the forging process of the crossbeam, so that the moving speed of the crossbeam of the forging press is prone to fluctuations, and in severe cases, the crossbeam may crawl , thus affecting the quality of forgings

Embodiment Construction

[0026] The control method for a forging press and the control system thereof according to the present invention can be used not only for a large die forging press for stable operation but also for a small die forging press for stable operation.

[0027] Such as figure 1 As shown, the forging press 60 includes a first die 14 and a second die 12 matable with each other to form a forging die. The first die 14 is usually fixed, and then the second die 12 can move following the movable beam 5 of the forging press 60 , so as to forge the forging blank 13 between the first die 14 and the second die 12 .

[0028] In addition, the forging press 60 also includes a hydraulic system 50 . The hydraulic system 50 includes a first oil pump 7 , a reversing valve 2 , a proportional valve 3 and a crossbeam drive cylinder 4 which are sequentially connected to the oil tank 1 . During the working process, the first oil pump 7 first delivers the hydraulic oil in the oil tank 1 to the reversing va...

Abstract

The invention provides a forging press control method and a control system of a forging press. The forging press control method includes steps of acquiring forging stock parameters, and calculating to obtain load deformation resistance model at the specific temperature according to the forging stock parameters, anticipated forging stock deformation displacement and forging stock deformation speed; calculating to obtain required opening degree of a proportional valve of a forging press in this forging according to the load deformation resistance model and an error appearing in the last forging process; adjusting the opening degree of the proportional valve to the calculated value and then forging the forging stock. According to the forging press control method and the control system of the forging press, forging process of a crossbeam can be frequently adjusted, the integral forging process is stable to run, and quality of forged pieces can be guaranteed.

Description

technical field [0001] The invention relates to a control method and a control system for a forging press, in particular to controlling a large die forging press to make it run stably. Background technique [0002] In recent years, with the development of aviation and aerospace technology, a new generation of aviation forgings is developing towards the trend of "large-scale, integrated, and precise", and widely adopts high deformation resistance, high deformation temperature, narrow deformation temperature range and deformation rate requirements. Strict titanium alloys are used as materials for aerospace forgings. This poses new challenges to aviation forging technology. A better solution is to use the isothermal forging process for large die forging presses, which can effectively reduce the deformation resistance of forging blanks, ensure sufficient dynamic recrystallization, and improve the quality of forgings. [0003] The isothermal forging process usually requires lar...
