Prensa JH21 is a type of metal stamping press machine designed for specific applications, such as metal stamping or punching. Among the various types of press machines, the JH21 model is the preferred option for industries requiring production runs of medium volume and excellent accuracy.
The JH21 shows a fixed bed and ram structure, in which the bed is the stationary part, while the ram is moved downwards with the help of a dedicated drive mechanism. The transparency of this machine increases the operator's effectiveness. With the right toolings set, insertions or die exchanges can be made quickly and straightforwardly. Prensa JH21 machines typically have parts that are easily visible. The type of press machine is often represented as an open C-frame. This design allows loading of the material from the frontal side of the machine, which is beneficial for working on metal pieces, such as plates and sheets.
Due to its open C-frame design, the machine provides reasonable power and ample working space for various applications. It is widely used in manufacturing industries, such as the automotive and consumer electronics industries, to form metal parts, create holes, cut gaskets, make seams, and do many other tasks that involve the processing of metals.
Due to its many benefits, including the operator's safety, suitability for heavy-duty tasks, minimal maintenance requirements, and high-performance efficiency levels, the machine is deemed to be highly contributing to production lines and the overall manufacturing industries.
The kind of press machine is assembled with quality components and is designed with advanced engineering techniques. This combination guarantees a solid framework with high widespread accuracy and a consistent press force throughout its lifetime. As such, the Prensa JH21 has rubber bumpers for noise and vibration reduction that also serve to enhance safety. The strike plate, formed of solid steel, can withstand regular use and damage, making it an exceptionally long-lasting product. Moreover, it has a heightened capacity for resistive energy. This means that even at lower levels of resistive energy, it is more efficient at conducting energy.
Specifications of a typical 21Jh automatic metal stamping press are as follows. The exact specifications will vary depending on the manufacturer and model.
This shows why correct maintenance is crucial. It will help the machine work longer and better, giving the products worth it. Here are key maintenance needs of the Jh21 punch press, along with details on what to do, the frequency of each task, and any other important info.
TheJH21 press machine performs various manufacturing tasks. Here are some of its typical usage scenarios:
Metal Forming
The JH21 press machine applies force to bend, cut, or stretch different metal types. Doors, fuel tanks, shelves, and car body parts are all made with this machine. The reason this machine is so common in the automotive industry is its accuracy and ability to do high-quality work without stopping.
Embossing
Embossing means raising a design on a flat piece of material. To make this nice-looking raised design, the flat piece of material goes through rollers that turn it. This process can be done with the help of theJH21 press machine. The embossing done by this machine is much more robust and clearer than other methods of marking metal or plastic.
Blanking
The process of blanking involves cutting out a specific shape from a larger piece of material. The remaining material is not used. The blanking die is used to cut the shape, and the workpiece goes through theJH21 press machine to complete the process. The blanking die delivers accurate and precise cuts, making it easier to carry out this process on various types of materials.
Deep Drawing
Deep drawing is a process where flat metal sheets are transformed into cups, boxes, or complex 3D shapes by stretching and pulling them. Going through theJH21 press machine helps make this process easier and more accurate. The deep drawing process can also be done several times, and the metal is still strong in the end.
Superplastic Forming
This process, superplastic forming, uses the superplastic qualities of certain alloys and materials. It can make very complicated and detailed shapes with the help of theJH21 press machine. Those shapes can be highly needed parts in aerospace, automotive, or medical industries. The superplastic materials are very strong but also very light. The setting up time for the superplastic forming method is short, and it can be done fast. It leads to making things with great precision, which fits the standards set in the industry very well. Using JH21 presses for superplastic forming also allows businesses to make a lot of products quickly while still making them with good quality.
When buying a stamping press machine, it is important to consider several factors to ensure the machine meets specific needs. These factors include the capacity and tonnage, floor space, control system, die and workpiece compatibility, available budget, safety features, reliability and maintenance support, as well as energy efficiency of the machine.
The most decisive factor for the prensa jh21 buyer will be the capacity or tonnage of the machine. JH21 stamping presses have capacities ranging from 60 tons to 2000 tons, and the capacity to choose will depend on the material to be worked and the shape or design changes to be made.
Buyers should be aware that stamping presses can be quite large, occupying significant floor space. It is imperative to consider the available floor space at the installation site when researching suitable machines. The machine's overall dimensions should be within the floor space available. In addition, suitable foundations or mounts must be prepared to ensure the stamping press is firmly and safely installed.
It is very important to choose a stamping press with a control system that the operator is familiar with or has experience in operating. Most modern stamping presses have electronic controls that are easy to operate and program, while older models may have mechanical or pneumatic controls. Some stamping presses have CNC control that allows precise control and automation of the stamping process.
The available budget will also be an important factor in determining the type and model of stamping press that can be purchased. Buyers should consider the safety features of the stamping press and the longevity and maintenance required for the machine. The safety features may be included in the budget but are necessary to protect the operator and other personnel. Safety features include guards, emergency stops, and interlocks.
When the stamping press is put into operation, the focus of attention will be on its energy consumption. Mechanical stamping presses tend to consume a lot of energy due to their design and work processes. Buyers can save money on energy costs by choosing machines with high energy efficiency.
Q1: What is a stamping press machine used for?
A1: A stamping press machine is primarily used for metal forming applications. It shapes, cuts, and punches various materials like plastic, metal, and leather into specified shapes and sizes.
Q2: What are the main types of stamping press machines?
A2: There are mainly two categories of stamping presses: the static press and the dynamic press. The static presses include hydraulic presses and flatbed vegetable presses, while the dynamic presses include mechanical stamping presses and eccentric presses.
Q3: What are the dominant components of a stamping press machine?
A3: The main components of a stamping press include the bed, ram, die, drive mechanism, and machine frame. The above components work in sync with each other to achieve accurate metal forming and stamping operations.
Q4: How does a stamping press machine operate?
A4: In general, a stamping press machine operator places the workpiece material in the designated position of the die. After that, the machine applies pressure to the material in order to cut it or shape it into the desired form. Once the operation is complete, the shaped workpieces are extracted for further processing, and the raw materials are ready for the stamping press machine to begin another cycle.
