Jx2020s is a fortified angle processing machine, the cylinder moving and the piston fixed.The board of mainframe, mould base, punching holder and some other parts are fortified, so that the machine can ensure higher pressure and heavy load for long-term and steady running. Punching part, cyliner moving and guided by eightside, piston fixed. Keep balance of the moving of punches, improve thestability of the cylinder. The fixation point of piston isspherical surface connect, eccentric-load can self-adjusted. Uprightness press The press cyl inder is upr ight , guide sur face sufficient, press-movingbalanced, with high power of press, reduce the impact and the recoi l of punchinig, and improve the stability of the machine.
