Hydraulic press for calibrating metal door panels

High precision hydraulic control
Adopting cartridge valve integrated system or electro-hydraulic proportional control valve, reliable action, small hydraulic shock, few leakage points, long service life.PLC control system realizes one-key operation, high degree of automation, and can realize two kinds of molding process: fixed-pressure and fixed-range, and has the function of holding pressure and delaying time.
Multi-stage pressure and speed adjustment
Pressure, downward speed and stroke can be adjusted according to the characteristics of metal plates to meet the processing needs of different materials.For example, the fast and slow speed oil circuit design can realize fast downstroke, slow pressurization, holding pressure delay and fast return stroke to improve production efficiency.
High-precision machining capability
Using mold repair technology, it can effectively avoid wrinkles, rupture and uneven force caused by plastic flow and plastic reinforcement of train door plate in press molding processing, and ensure processing precision.

From high-speed moving train to general-speed bus, from subway to overseas railroad projects, the application scenario of train door shaping hydraulic press is very wide:
Dynamic train section/high-speed railroad vehicle section: Repair the oval deformation of the door frame and the sagging problem of the door body of CR400AF/BF, CRH380 and other high-speed dynamic train set sliding doors;
General-speed train maintenance base: dealing with weld cracking and door body distortion of steel swing doors of 25G/25K coaches;
Subway Vehicle Section: correcting the excessive gap between the door frame and the car body caused by frequent switching of the inner hidden door of A/B/C type subway cars;
Overseas railroad projects: adapting European EN standard and Japanese JIS standard doors, helping China's high-speed railways "go out" maintenance.
