Практичний посібник із розуміння пресу для штампування металів

Тема металу залишалася популярною в кожну епоху. Він особливо відомий у зв'язку з сучасними технологіями. Однак насправді штампування металу  - це давнє ремесло, яке протягом століть стало передовою технікою.

Що таке штампування по металу?

Штампування металом  - це керований процес деформації, при якому тіло змінює свою форму під впливом надмірного тиску. Завдяки такій обробці металевим виробам надаються найрізноманітніші форми, необхідні для виконання своїх функціональних обов'язків.

Штампування поступається частинам невеликої товщини, оскільки згинання товстих виробів дуже проблематично.

Як здійснюється штампування металу?

Штампування металом дозволяє швидко і точно сформувати вихідний листовий матеріал у готовий виріб.

Цей процес полягає в деформації металу під дією спрямованого тиску. У цьому випадку матеріал змінює свою форму, зберігаючи початкову товщину листа.

 

Основні види штампування металу

Цей спосіб переробки застосовується в малих, середніх і великих обсягах на галузях промисловості.

Stamping of metal products is used in almost all industries. Moreover, it allows you to create any kind of detail. This technology has a very long history and is now actively developing.

New methods are constantly emerging that use forces of different origins other than gravity. Similarly, deformation occurs under the influence of:

• hydraulic pressure
• electric current
• Magnetic field, etc.

Next, we will consider issues related to the principle of operation of:

• штампування металу
• types and
• methods of metal deformation
• The use of products created in this way in various industries.

What is sheet metal deformation?

Deformation of sheet metal can be carried out under the influence of high pressure. Based on this, all types of stamping can be divided into two large groups:

• cold;
• гарячий

Generally, both types have advantages and disadvantages that delimit the scope of their use. Cold stamping is carried out at a temperature below the melting point of the metal.

Furthermore, this avoids shrinkage during cooling. But it imposes restrictions on the shape of the final product. This method creates parts without a large number of embossed elements, for example, parts of a car body.

The main requirements for the material used during cold штампування металу are high ductility. In addition, the method is suitable for:

• low-carbon and alloy steels
• мідь
• Латунь
• aluminum and magnesium alloys, and

 The following is required for metal stamping:

• A soft pad, a metal foil and embossing tool.
• If you want to try out the technique first, you can use a simple embossing pen and a teaspoon as a tool.
• If you like this hobby then you should get the right tools. It is much easier to achieve much, much better results.
• The special штампування металуtools look a bit "old-fashioned". But also very stable - and that's exactly what they are! They serve their purpose better than some new tools. Because they are stable and fit well in the hand.

Why metal stamping?

Штампування металом is an important manufacturing process, depending on what stamping requires shape and function. The advantages are:

1. high production rate
2. consistency and
3. Low cost.

Штампування по металу technology is applied in many industries. Such as:

• Автомобільна
• heavy industry
• electronic industries
• electronic components
• hardware accessories
• Vehicle accessories.

Stamping molding technology is a technology for forming a desired shape by combining technologies. Such as:

• Bending
• Drawing
• punching, and
• Cutting metal plate materials.

It has the advantage of being able to manufacture large numbers of products at low cost. It is one of the main technologies for manufacturing metal parts.

Main mechanical hammers used in forging

Modern forging machines mainly include mechanical hammers and press machines.

First, there are two main types of mechanical hammers used in forging:

1. air hammers
2. and spring hammers

What is hydraulic metal stamping?

A hydraulic press is a press machine that uses the pressure of a cylinder into which water or oil is fed to perform processing. The load and speed can be controlled by adjusting the hydraulic pressure sent to the cylinder.

The potential of cold sheet metal stamping

The sheet штампування металу and forming is a production process that allows you to create objects and metal products starting from a lamina. It is compressed and molded into different shapes and sizes depending on the type of tool.

The sheet is applied in many sectors, from furniture to electronics, from objects to heating, from the food to the industrial sector.

The stamping of the sheet allows producing high quality objects at low costs. Even when the shapes and characteristics are very elaborate and rich in details.

 

This is because the machinery used in production and the production processes are highly sophisticated and cutting edge in every respect.

The fastest and most efficient sheet metal pressing technique is the cold one. Let's look at how it works.

What is cold stamping of sheet metal?

The cold sheet is the most convenient and rapid type of industrial molding. Because it is operated at ambient temperature, without requiring the heating of machinery and metal plates before machining.

Generally, it greatly reduces the waste of energy, economic and temporal. This is why many companies use it for sheet metal stamping in Turin and throughout Italy.

Conclusion on metal stamping

It's used for a very long time. Since it comes from the forging of metals - a process that develops together with humanity. without which it is impossible to imagine the creation of tools, construction tools and weapons.

Modern methods of manufacturing parts require not only high precision, but also material savings. While cutting metal, a very large part of it goes into chips  maximum rationality. It consumes material, giving it a shape that practically does not need further processing.

Although the presses used for штампування металу are constantly evolving, increasing power and productivity. Their technical characteristics sometimes do not allow the creation of parts of very large sizes.

In this case, alternative methods come to the rescue. Such methods use hydraulic, explosive and electromagnetic forces.

The introduction of these methods into production allows you:

• to reduce the consumption of materials
• increase the accuracy and
• reliability of products and
• speed up the production processes.
