Hydraulic Press for Forming Dished Head

40MN Dished Head Hydraulic Press

LS Heavy Industry Engineering Co., Ltd. designs and manufactures 40MN hydraulic press used in pressure vessels. The push down type hydraulic press is with four circular columns. The plunger rods of press cylinders connect main slider through hinge joints. The plunger rods of press cylinders connect blank holding slider through hinge joints. All motion parts are automatic lubricated, e.g. guiding area of moveable crossbeam, motion area of moveable table.

In hydraulic system, prefill tank is on the top of the press for the minimum distance to press cylinders, the cylinders are directly driven by oil pumps. All pipe clamps are shock-proof installed. The oil temperature, oil pressure, oil liquid level is automatically detected, displayed in both hydraulic station and operation room. In case failure, automatic alarms. The temperature data of cooled air is input through touch screen

Programmable control unit is the core of automatic control system to the control of press, auxiliary equipments, as well as monitoring, diagnosis, fault alarm, and communication, management and coordination to the whole system.


SIEMENS S7 series PLC connect distributed I/O RST (remote station) through PROFIBUS-DP. High flexibility for modular exchange due to advanced design is for meeting different demands.
