Press power will be set accurately, with excessive precision and small tolerance, particularly appropriate for precision forging. J58k series CNC electrical screw press control system refractory press machine adopts SIEMENS PLC and ABB frequency converter, with excessive reliability, excellent performance.
Electric screw press machine has a simple design, which permits the operator to operate it conviently. Friction screw press can be availed in capability starting from sixty three tons as much as 15500 tons. Able to driving each asynchronous and synchronous motor of screw press machine.
Shortly before the impact of the higher half of the forging die, secured to the slide 7 upon the forging work-piece mendacity within the lower half of the forging die, the strains 31 to the axial piston motor 26 are quick-circuited, because the magnetically controlled four-means valve 41 is moved from its relaxation position (as shown in FIG.
Screw press is a significant forging tools, its most essential advantage is precise energy management which ensures high course of reliability and repeatability, moreover, utilizing low pace giant torque motor directly driving the press can remove the clutch, gear, belt, et al driving machine, so that the ability consumption may very well be lowered effectively.
A compact design and an increase in operational reliability are achieved if, every axial piston motor or every pair of axial piston motors which is related to a pinion and the associated reversible pump are disposed in a closed circuit which also incorporates the control means for feed strain and a number of-stage strain controllable in a single stage as braking strain and which is linked to a refill pump.
In machinery industry, it may end blanking, bending, correction, precision pressing and punching in forging process. Hanging vitality can not be controlled accurately and simply. 7. Electric screw press has no lower dead level, it is simple to vary the die without adjusting the height of the die.
