An EV battery chassis shield is a protective device installed beneath a vehicle’s battery system or chassis to safeguard critical components against external impacts and environmental corrosion. Classified as an automotive accessory, it primarily protects the chassis and the components mounted on it. Aluminum alloy chassis shields are highly favored for their lightweight nature, excellent corrosion resistance, high structural strength, and superior shock-absorbing properties. These components are manufactured through a single-step stamping process utilizing a hydraulic press.

PDH‘s EV battery chassis shield hydraulic press is specifically designed for the precision stamping of aluminum alloy underbody shields. The machine features a robust “three-beam, four-column” frame structure and utilizes a dual-cylinder configuration to ensure uniform force distribution across the worktable. It is equipped with a bottom ejector cylinder, a servo motor, and a PLC control system.

Furthermore, its four-column guiding mechanism ensures high precision and rapid operation during the stamping of aluminum alloy chassis shields. By simply changing the mold, the hydraulic press machine can be utilized to produce a wide variety of automotive components in various shapes and sizes—including body panels, brake pads, axle housings, bumpers, wheel spokes, and more.

Features of the EV Battery Chassis Shield Hydraulic Press

1. It adopts a four-column structural design. Through finite element structural analysis and optimized design, it can withstand significant stamping pressures. This ensures the rigidity and stability of the machine frame during processing, thereby guaranteeing the precision of the forming of the automotive battery protection plates.
2. It features a spacious worktable and a generous daylight opening (clearance height), capable of accommodating the processing requirements of automotive battery protection plates of various dimensions. This facilitates the convenient installation of molds and the easy loading and unloading of workpieces.
3. The hydraulic system delivers stable and precisely adjustable pressure, ensuring uniform pressure distribution throughout the stamping process of the battery protection plates. This results in superior forming quality of the plates, thereby enhancing the safety and stability of the battery system.
4. It is equipped with an integrated electromechanical-hydraulic safety protection system. Utilizing centralized control via a PLC and touchscreen interface, the machine offers multiple operating modes—including adjustment, manual, and semi-automatic—making operation simple, convenient, and easy to master. This effectively reduces operator workload and boosts production efficiency.
5. With PDH’s deep drawing hydraulic press for automotive battery chassis protection plates, parameters such as working pressure and stroke can be flexibly adjusted within specified ranges to meet specific process requirements. This enables the machine to rapidly adapt to the production demands of automotive battery protection plates across a wide variety of models and specifications.

Components of a Hydraulic Press for Car Battery Chassis Shields

• Main Frame: Composed of a “three-beam, four-column” structure, which includes components such as the upper beam, sliding beam, worktable, and columns. These components are predominantly fabricated from high-quality steel via welding and subsequently undergo tempering treatment to relieve internal stresses, thereby ensuring they remain free from deformation during high-intensity operational processes.
• Electrical Control System: Consists of power circuits and control circuits, utilizing a PLC (Programmable Logic Controller) for operational management. By processing commands and signals transmitted from master control elements (e.g., selector switches, pushbuttons) and detection elements (e.g., limit switches, pressure relays), the system achieves precise control over the pressure and displacement of the hydraulic actuators (e.g., hydraulic cylinders).
• Hydraulic System: Comprises energy-conversion devices (e.g., pumps and hydraulic cylinders) and energy-transmission devices (e.g., oil tanks and pipelines). Under the electrical control system, the hydraulic system drives the sliding beam through various operational cycles.
