The Invernizzi DMV 1 mechanical press , a used 40-ton machine, is an excellent choice for those seeking reliability and precision in metalworking. This model features a single connecting rod , making it particularly suitable for punching and shearing operations with a wide variety of materials and thicknesses.

What the car looks like

Visually, the Invernizzi DMV 1 has a sturdy structure, typical of machines built to last. It is designed for stability during operation, with a solid base and a work surface that provides ample space for various operations. Its paintwork may show signs of wear, typical of used machinery, but this does not affect its mechanical performance. Moving parts, such as the slide and feeder, are also in good condition, ready for immediate use.

Technical characteristics

One of the strengths of the Invernizzi DMV 1 is the ability to adjust the stroke , with a range between 12 mm and 80 mm . This feature makes the machine versatile, allowing it to be adapted to different production needs. The slide adjustment can be set up to 50 mm , which makes it easy to optimize the process based on the type of mold used.

Another important feature is the machine's adjustable speed, ranging from 50 to 200 strokes per minute . This flexibility allows the operator to adjust the working speed depending on the material being processed and the type of operation, thus ensuring an excellent balance between productivity and precision.

Procedure for use

Invernizzi DMV 1 mechanical press is simple and intuitive to use, although it does require some experience to fully exploit its capabilities. The control panel allows you to adjust key parameters, such as stroke and working speed. The machine is designed to ensure a continuous production flow, making it ideal for mass-produced blanking and forming operations.

Accessories and components

As a used model, the Invernizzi DMV 1 can be customized with various accessories to further improve production. Among the accessories that can be combined with this press are:

• Automatic feeding systems , to improve efficiency and reduce downtime between one process and the next.
• Interchangeable molds , custom-designed for specific jobs, suitable for taking full advantage of the machine's power.
• Automatic lubrication systems , to extend the life of moving components.

Formulas to optimize use

To get the best performance from the Invernizzi DMV 1 , it is essential to adjust the parameters according to the material and the type of operation. A useful formula for calculating the force required during a process can be the following:
F = S × t × Rm F = S \times t \times Rm
$F$ $=$ $S$ $\times$ $t$ $\times$ $R$ $m$ Where:

• F is the force required (in tons),
• S is the surface area of ​​the material being worked (in mm²),
• t is the thickness of the material (in mm),
• Rm is the ultimate tensile strength of the material (in MPa).

Using these parameters, you can correctly adjust the stroke and speed of the machine, thus ensuring optimal use without overloading the press.

Maintenance and safety

Maintenance of the Invernizzi DMV 1 is crucial to ensuring optimal performance and extending the machine's life. Operators must perform periodic checks on critical components, such as the connecting rod, slide, and fuel system. The use of specific lubricants is recommended to reduce wear on moving parts.

In terms of safety, although the machine was produced before the latest CE standards, it is possible to upgrade it with modern safety devices, such as light curtains emergency stop systems , to comply with current regulations and ensure a safe working environment.

How to evaluate a good used one

Buying a Invernizzi DMV 1 can be an excellent investment, provided you carefully evaluate the machine's condition. It's essential to check the integrity of the connecting rod, the condition of the guides, and the functioning of the accessories. A good indicator of a quality used machine is the condition of the supporting structure and internal mechanisms: moderate signs of wear are acceptable, but you should ensure there are no structural defects.

Sectors of use

The Invernizzi DMV 1 mechanical press is ideal for sheet metal working and metal component manufacturing . With its 40-ton capacity and adjustable stroke and impact rates, it can be used for a variety of applications, from punching precision parts to forming thicker sheet metal.

Why buy used

Purchasing a used baler like the Invernizzi DMV 1 represents an opportunity to obtain a high-performance machine at a fraction of the cost of a new one. Used machines, if properly maintained, can provide years of reliable service at a very competitive price.
