Definition:
Presses, since ancient times, are used in virtually all industries, used to act on many different materials, cold forming or hot forming, in any operation that requires intense pressure: packing, squeezing, forging, stamping, flush-mounted, laminating, stretching. A widely used process in manufacturing, precision metal forming is a cost-effective process for producing precision metal parts used across several industries. So it is used in automobile, aviation, shipbuilding, electrical appliances, radio, light industry, and other sectors. We will try to explore some of the wide range of applications of presses in our lives in the following.
How a Press Works
Using a mechanical press is a three-step process that begins with placing the material on the die, so it stays in place—then actuated either hydraulically/pneumatically or mechanically. Finally, the metal will be pressed between the two halves of the tool, and it will be pressed into the desired shape.
Power Press is a widely used type of press machine in the workshop. The constructional feature of a power press is almost similar to the hand press, the only difference being, the ram, instead of driven by hand, is driven by power. The power press is characterized as mechanical or hydraulic according to the type of working mechanism used to transmit power to the ram.
Press Products are All Around You
Presses can form a wide array of products of different sizes, from simple shapes requiring a single process to sophisticated products requiring multiple processes.
a. Press for the automotive industry
Press is the critical equipment of stamping workshops in the automobile industry. It is mainly used to produce various stamping parts for automobile bodies. In the process of completing the drawing and trimming of auto stamping parts in cooperation with the die, the press needs to adjust the height of the slider to adapt to the dies of different heights, and its adjustment accuracy and stability directly affect the quality of auto stamping parts. In China, FAW Toyota Motor, Guangzhou Toyota Motor, BMW Brilliance, FAW Car, FAW Volkswagen Geely Automobile all use servo presses. With its continuous application in the field of automotive production, the advantages of servo presses are becoming more and more obvious. It meets the need for an efficient and energy-saving automated production line.
Shock absorber
With the popularity of automobiles, people’s requirements for the performance of automobiles, such as power, operational stability, and comfort, have become higher and higher. The competition in the automobile industry is also becoming more and more fierce, and the requirements of automobile manufacturers for automobile parts are also getting higher and higher. As one of the essential modules in the car, a shock absorber has a great influence on the operating stability, comfort, and other performance of the car.
Bearings
Bearing press fitting is one of the most common and practical uses of servo presses. Bearings are moving parts, and the effect of press-fitting directly affects the performance and life of a vehicle or product, or equipment. Servo press fitting machine can solve press-fitting overload very well because the speed and press-fitting force are adjustable. With the pressing force and displacement detection, can effectively judge the press-fitting effect, press-fitting parameters can be saved, adapt to the host plant on the traceability of press-fitting parts.
b. Presses in Appliances
Flat-screen TV body panels and built-in compressors for refrigerators, air-conditioners, and washing machines are manufactured by press forming.
Lamps are manufactured in metal lampshades, umbrellas, bowls, and shells by stamping and forming. The required material is first cut on the infeed machine, pressed on the press, trimmed by the trimming machine, and finally polished and plated to form the final product.
c. Presses in electronics
Flat-screen TV body panels and built-in compressors for refrigerators, air-conditioners, and washing machines are manufactured by press forming.
d. Pressed products in your kitchen
Products formed using presses are shown in the kitchen—for example, Stainless steel sink, stainless steel cooking pots, knives, spoons, and doorknobs.
e. Press products in decoration
The watches we wear are also made by presses. The press uses pressure to shape the case, using a large metal press. After placing the metal block into the press with a concave die, the head of the concave die is pressed into the block from top to bottom with a thrust of up to 30-60 tons, cutting out the case profile. After going through the same process several times, each time replacing the press with a more precise concave die, the final shape of the case is created.
Stamping is the use of presses and dies to apply external force to metal plates and tubes to
produce plastic deformation or separation, clearly replicating the surface shape of the die, thus obtaining the desired shape and size. Compared with the traditional casting process, stamping can produce the same product repeatedly in large quantities and economically in a short period of time, and the product has a smooth surface and stable quality, which greatly reduces the workload of subsequent processes, improves production efficiency and reduces production costs. Therefore, the stamping process has received more and more attention in the jewelry manufacturing industry, and its application is becoming more and more widespread.
Preventive Maintenance Tips for Your Press
- Knowing how to care for your press is one of the most important parts of running an efficient business. Checking on a press to keep it in good working order is more than just a smart operating procedure – it can pay off for manufacturers. By knowing when a press is running well or requires attention and by consistently conducting preventative maintenance, the lifespan of a press can be significantly increased. The most important is to get to know the machinery and make a written preventive maintenance schedule, which will help keep the equipment in peak condition for many years to come. Follow these tips to extend the lifespan of your investment and get optimal performance
- Daily maintenance checks are necessary. Should use a checklist and records maintained of all performed maintenance and repair work. Regularly record keeping allows your company to quickly diagnose and address problems.
- Cleanliness is important! Dust can be detrimental, especially for electrical components. As an essential piece of regular maintenance, proper cleanliness can go a long way in extending the life of your machine。
- Proper and Safe use of the equipment. Safe and correct operators contribute heavily to the long-term success of the life of the machine.
