Detailed Product Description

Straight Side Deep Drawing Hydraulic Press Stamping Line

Detailed Product Description

Straight Side Deep Drawing Hydraulic Press Stamping Line / Tandem Press Line is deep drawing, shallow drawing,

fine blanking, flanging and other compound processing of thick sheet metal and thin sheet metal on aviation industry,

automobile industry, electrical household appliances industry, petrochemical industry, railway equipment industry

This serial is developed basis of the licensed German technology, it fully integrates our innovation and know how including

high productivity, energy saving and environment friendly solutions, the presses are well suitable for various thick or sheet

metal deep drawing, blanking and piercing process, and complex forming as well, The presses have been widely operated

in the aerospace, automotive, high speed rail way and home appliance fields.

The further development of RZU serial presses are listed as the National key machine tool project of the year 2010. Over

140 tandem press lines have been delivered to the automotive industry today.

The Main Features

*The presses are mono block or straight side steel welded structure according to difference size and tonnage , the ram moves

along the 8-fold guide way with high eccentric loading resistance and precision. The accuracy of the press is as per

JIS B 6403-1994-1 the first grade.

*The control is basis of the latest close loop proportional control technology, the position and action signals are picked up by

precise Encode, the driven system of the press consists of the latest digital pump and servo valves which offer a flexible flow

rate and force setting.

*The presses are furnished with comprehensive safety solutions including Twin safety valve for the hydraulic system, a

comfortable upper platform for possible maintenance

*Various function modules including Numerical Controlled Upper and lower cushion, Full capacity shock absorber system,

automation system are available per choice.

*Full tonnage Shock absorber system is developed basis of licensed Germany technology, with this optional device the press

can be operated for full tonnage stamping and piercing, the key point of the system including very low noise, no extra energy

required and it can trace the real damping force automatically.

*Automatic Quick Die Changing system including: Rolling bolster and Tooling Identity, Die centering and automatic clamping

system.
