2. Technical Descriptions :
2.1 Structure
The structure design through the finite element optimization design, the overall performance of the press are practical, durable, high rigidity and high reliability.
The welded C frame adopts high qualified steel, through Aging treatment to eliminate welding stress; ensure the machine service life and precision of the durability.
Ram operating depend on guidance of pillars and bushes, and realize upward and downward motion.
The high speed composite cylinder made from high quality forged steel 45, the piston rod surface through intermediate frequency quenching treatment, the hardness above HRC45 then for chrome plated process, seals material of cylinder are imported to ensure reliable sealing.
Stroke limit, the limit of the press adopts imported photoelectric switch control, and set the upper and lower limit switch protection, to ensure the slider within limited stroke distance .

2.2 Hydraulic Control System
Hydraulic station layout is reasonable, is helpful to check the maintenance
Hydraulic control system adopts advanced integrated structure to meet the fast response, anti-pollution ability, no leakage, reliable performance requirement
There is bearing insurance loop in the hydraulic system, should guarantee the slide ram can be stop at any position, and set the overload protection circuit, to ensure the safety in the process of work.
Hydraulic system set up corresponding pressure check points, in order to facilitate debugging, inspection, maintenance.
Hydraulic line connected by flange, distribution uncluttered and firm.

2.3 Electrical control system
Adopt PLC programmable control technology, with three functions of setting adjustment, manual and semi-automatic.
Slide Stroke controlled by imported photoelectric switch, and set the upper and lower limit switch, for protection.
On the operation panel set with the emergency stop button, press the stop button to stop all actions.
The main electric elements adopt domestic famous brand products.
Equip with movable double hands button operation platform.
3. Safety Protection Measures:
Work station and moveable station have emergency stop button, press the stop button, to stop all action.
Upper and Lower limit set with limit protection switch.
Setting with overload protection, the hydraulic system is equipped with safety valve, to ensure no overload.
