The invention discloses a pneumohydraulic pressure cylinder equipped on a tin dipping machine. The pneumohydraulic pressure cylinder comprises a cylinder body; a pressure cylinder body is fixedly arranged on the outer surface of the upper end of the cylinder body; an acoustic barrier is fixedly arranged on the outer surface of the same side of the cylinder body and the pressure cylinder body; a rear piston is movably arranged at the upper end of the interior of the cylinder body; a front piston is movably arranged at the bottom end of the interior of the cylinder body; a front cover is fixedlyarranged on the outer surface of the bottom end of the cylinder body; and flanges are fixedly arranged on the outer surfaces of the two sides of the front cover. The pneumohydraulic pressure cylinderequipped on the tin dipping machine has the advantages that the acoustic barrier, a spring and a protective inner cover are arranged so that the noise pollution generated in the using process can beeffectively weakened, the relative movement between the rear piston and the front piston can be well promoted, the energy consumption of the pneumohydraulic pressure cylinder can be effectively reduced, the pneumohydraulic pressure cylinder is relatively environmentally friendly, the damage to the pneumohydraulic pressure cylinder caused by high-speed operation can be effectively prevented, the service life can be greatly prolonged, and better application prospects can be brought.
