The Invernizzi DMV 1 mechanical press , a 40 ton used machine, is an excellent choice for those looking for reliability and precision in metalworking. This model is equipped with a single connecting rod , which makes it particularly suitable for punching and shearing processes with a large variety of materials and thicknesses.

What the car looks like

Visually, the Invernizzi DMV 1 has a robust structure, typical of machines built to last over time. It is designed for stability while working, with a solid base and a work surface that offers ample space to handle different operations. Its paintwork may show signs of wear, typical of a used machinery, but this does not affect its mechanical performance. The moving parts, such as the slide and the power supply, are also in good condition, ready for immediate use.

Technical characteristics

One of the strong points of the Invernizzi DMV 1 is the possibility of adjusting the stroke of the slide, with a range that varies 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 facilitates process optimization based on the type of mold used.

Another relevant data is the machine's ability to operate with an adjustable speed, varying between 50 and 200 strokes per minute . This flexibility allows the operator to adapt the working speed depending on the material processed and the type of operation, thus ensuring an excellent balance between productivity and precision.

Usage procedure

Using the Invernizzi DMV 1 is simple and intuitive, although it requires some experience to fully exploit its capabilities. The control panel allows you to adjust the main parameters, such as stroke and working speed. The machine is designed to ensure a continuous flow of production, making it ideal for serial blanking and forming operations.

Accessories and components

Being 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 another.
• Interchangeable moulds , tailor-made for specific processes, suitable for fully exploiting the power of the machine.
• Automatic lubrication systems , to extend the useful life of moving components.

Formulas to optimize use

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

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

Using these parameters, it is possible to 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 ensure optimal performance and prolong the useful life of the machine. 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 of 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

Purchasing a Invernizzi DMV 1 can prove to be an excellent investment, as long as you carefully evaluate the condition of the machine. It is 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 vehicle is the condition of the supporting structure and internal mechanisms: the presence of moderate signs of wear is acceptable, but you must ensure that there are no structural defects.

Sectors of use

The Invernizzi DMV 1 mechanical press is ideal for the sheet metal processing and the production of metal components . Thanks to its 40-ton power and stroke and stroke adjustment, it can be used in various applications, from blanking precision parts to forming thicker sheet metal.

Why buy used

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