Abstract

The invention discloses a hot stamping forming hydraulic machine system and belongs to the field of hot stamping forming hydraulic machine systems. By means of the hot stamping forming hydraulic machine system, stable operation of the system can still be ensured when the press speed is increased to 1000 mm/s, workpieces can be rapidly and evenly cooled, and the die temperature yield is made to tend to be constant always. In order to solve the problem of pressing of a press on the conditions of the high speed and the high takt, the production takt is effectively improved, and therefore the yield is improved. By using the hot stamping production time, the takt is improved to 6-7 times/minute, the output is increased by 30% or more on average, the problem of insufficient cooling or uneven cooling during forming of workpieces is effectively solved, the workpieces have high strength and good appearance after molding, the die heat balance problem is effectively solved, as long as the power is continuously supplied, the production line can achieve production always, the press energy consumption is effectively reduced, the purposes of energy conservation and environment protection are achieved, pipe appearance is attractive, and maintenance is easy.
