Automobile door panels are a type of stamped part. Their production process requires compression and stretching in conjunction with dies. A hydraulic press applies tensile force to the sheet material through the die, generating uneven tensile stress and strain. Consequently, the sheet material gradually expands in contact with the die until it is completely aligned with the die surface.

PDH’s 630T automotive door panel stretching hydraulic press features a three-beam, four-column, four-nut structure, facilitating press preload and precision adjustment. The three main beams (upper crossbeam, slide, and worktable) are welded and annealed Q355B, minimizing deformation and ensuring excellent precision retention. The columns are made of 45 steel with a hard chrome plating. The slide is guided up and down by the four columns. The guide bushings in the four columns are oil-free, lubricated bearings, which improve friction, reduce frictional resistance, and prevent scratches and strain on the columns.

Features of the 630T Car Body Panel Press

1. Computer-optimized structural design, available in four-column and frame types. The four-column structure is simple, economical, and practical. The frame structure offers superior rigidity, high precision, and strong resistance to off-center loads.
2. The hydraulic control utilizes an integrated cartridge valve system, resulting in low impact, reliable operation, long service life, and minimal leakage.
3. The movable crossbeam features two-stage speed control: high speed for no-load drawing and slow speed for die-drawing. The movable crossbeam has upper and lower limit protections and an adjustable stroke.
4. The operating pressure and stroke can be adjusted to meet process standards within the specified range, ensuring easy operation.
5. It can perform both constant pressure and constant stroke forming processes, with an adjustable pressure hold delay function.
6. The PLC-controlled electrical system offers a compact structure, flexible operation, and reliable operation.
7. The main rod utilizes a four-nut structure, which improves preload performance and maintains long-term precision stability.
8. The main hydraulic seals are from renowned brands, providing reliable sealing performance. 9. The increased filling tank volume ensures rapid filling, reduces pressurization time, increases heat dissipation area, and reduces oil temperature.
10. The hydraulic system can be mounted on top, minimizing footprint, providing a spacious workspace, and simplifying operation.
