What are the common stamping process applications of fixed table presses?

In daily production and life, various metal products around us, such as automotive parts, furniture accessories, electronic device casings, etc., are often stamped and processed by fixed table presses. These seemingly ordinary metal products contain various clever stamping techniques and applications of fixed table presses behind them. In order to meet the production needs of different products, fixed table presses continuously expand the boundaries of their stamping processes. So, what are the specific applications of its common stamping process?

1. Punching process: the core link of basic processing

Punching is the most fundamental process application of fixed table presss, including two forms: cutting and punching. The material cutting process separates the sheet along the closed contour by closing the mold, obtaining the desired shape of the part; The punching process involves punching through holes or blind holes on the board. The rigid body and high-precision guide rail system of the fixed table press can ensure the verticality and smoothness of the punching edge, meeting the strict requirements for dimensional accuracy of electronic components, automotive sheet metal parts, etc. Its punching force range usually covers 0.5-500 tons, suitable for the processing needs of metal sheets with different thicknesses (0.1-10mm).

2. Bending process: key to forming three-dimensional structures

The bending process uses a fixed table press slider to drive the upper mold to press down, causing plastic deformation of the sheet metal in the mold cavity, forming V-shaped, U-shaped or complex bending structures. This process requires high rigidity of the equipment, and the cast iron body of the fixed table press can effectively absorb stamping energy and prevent dimensional deviations caused by vibration. The bending angle control accuracy can reach ± 0.5 °, suitable for manufacturing components such as electrical enclosures and cabinet frames that require precise assembly. Some models are equipped with angle compensation devices that can automatically correct material rebound and improve product consistency.

3. Deep drawing process: forming technology for complex shapes

The deep drawing process utilizes the slider pressure of a fixed table press to pull a flat blank into a concave mold to form a hollow cup-shaped or box shaped part. This process requires equipment to have stable pressure output and precise stroke control. The fixed table press can achieve deep drawing processing with a drawing coefficient (the ratio of blank diameter to drawn part diameter) as low as 0.5 through a hydraulic overload protection system and closed-loop position feedback. Typical applications include the manufacturing of automotive fuel tanks, stainless steel insulated cups, and other products, with a deep drawing height to diameter ratio of over 1.5, meeting the design requirements of complex structures.

4. Forming process: Fine processing of surface features

The forming process forms features such as embossing, flanging, and bulging on the surface of the sheet metal through the local pressure of a fixed table press. The embossing process can press text, patterns, or reinforcing ribs on the surface of parts to enhance product aesthetics and structural strength; The flanging process involves extruding the edge of the mold to bend the material of the hole edge outward or inward, forming a connecting flange or sealing structure; The bulging process utilizes liquid or rubber media to transmit pressure, causing local expansion of the sheet to form a convex or spherical structure. The precise pressure control (± 1% rated pressure) and high-speed response capability (up to 300 strokes per minute) of the fixed table press ensure the dimensional stability and surface quality of the forming features.
With the continuous upgrading of the manufacturing industry and the continuous innovation of technology, the stamping process application of fixed table presss will also usher in new development opportunities. In the future, we have reason to expect its processes to be more refined and intelligent, able to meet more complex production requirements, explore more emerging application areas, and inject continuous power into promoting technological progress and industrial upgrading in various industries.
