Hidrogarne MV-800E/NC Four-Column Hydraulic Press For Drawing and Cutting Work

Machine Type: Customized Hydraulic Presses

Series: Forming and Stamping

Description

The MV-800E/NC four-column hydraulic press belongs to the M/NC series and is custom-designed to achieve greater precision and capacity, specifically manufactured for deep drawing and cutting tasks.

Equipped with a top and bottom table made of C45E steel, machined with DIN-650 slots to ensure minimal friction in the vertical movement of the top table through the installation of maintenance-free bimetallic bushings and perfect parallelism achieved by four chromed and ground cylindrical columns.

It uses an optimized hydraulic system with a pressure of 265 Bar, ensuring prolonged durability and reliability in its performance.

It meets and satisfies all essential safety and health requirements according to CE regulations.

Structure and Tables

Consists of three electrowelded blocks made exclusively of S355JR steel.

Stabilized and machined at the end of the welding process to ensure perfect parallelism and precision.

Calculated and designed using finite element software.

The bottom table is equipped with a 250 Tn hydraulic cushion with a useful surface of 750x750 mm.

Incorporates a SIEMENS KP-700 COMFORT NC for the regulation of the top table stroke, speed changes, working pressure, and the regulation of the hydraulic cushion in stroke and pressure.

Cylinder and Hydraulic Group

Single-acting cylinder with lapped sleeve, chromed piston, and maintenance-free anti-wear guides.

The hydraulic group is installed entirely on the top of the press.

The hydraulic group includes a silent Denison hydraulic pump and an air-oil cooler.

Includes:

Decompression system,

Pressure solenoid valves,

Pre-fill valves,

Communication valve,

Check valve,

Pressure relief valve,

Anti-fall valve.

Four side cylinders installed for ram compensation during cutting and an anti-ram valve.

Electrical Installation and Safety

Incorporates a Siemens SIMATIC S7 1200 safety PLC and a 7” KTP-700 COMFORT touch screen located on the electrical panel. Allows programming of semi-automatic and automatic modes, power, stroke, and dwell time of the main cylinder and the cushion. It has a storage capacity of 300 recipes, each recipe can program all the above values.

Prepared for Industry 4.0.

The electrical panel includes a selector to choose the type of work to be performed in manual “adjustments” or automatic “production” mode.

The electrical and hydraulic maneuvers are redundant and self-controlled. They incorporate an additional safety block and self-control devices for maneuver and safety. Includes verification and certification of correct functioning and the safety distance for the photocells.

The operation is carried out by a low-voltage electric pedal.

To ensure safety, it includes category IV photoelectric barriers located in the front working area, two fixed side guards, and a practicable guard with a magnetic disconnection detector located at the rear.
