1. Longitudinal Support Roller Table
Constructed with a base and supporting rollers, this component is purpose-engineered to provide stable support for sheet materials. Each roller is outfitted with bearing assemblies at both extremities to guarantee secure and seamless operation. Boasting exceptional structural rigidity and strong impact resistance, the rollers enable consistent, low-friction movement of sheets across their surface.
2. Centering Device
This device is configured with 5 sets of centering and positioning mechanisms, wherein the two centering blocks are synchronously driven and guided by precision guide rails. During operational cycles, the air cylinder actuates the two pairs of centering blocks to move toward each other, realizing accurate centering and secure clamping of the sheet material. Linear positioning capability ensures that width deviations are evenly distributed on both sides of the sheet, sustaining consistent processing precision.
3. X-axis Main Clamp Feeding Device: 2 Sets
This beam punching machine line comprises a servo motor, precision reducer, floating hydraulic clamp, precision linear guide rail, precision rack, and support structures. The servo motor transmits power to drive the helical gear into rotation via the precision reducer, and further converts rotational motion into linear motion through the rack mechanism. Guided by the precision linear slide rail, the feeding components execute accurate feeding operations, ensuring precise and stable sheet material conveyance. The feeding clamp adopts a floating structural design, which offers strong adaptability to slightly warped sheet materials. It is characterized by high clamping force, reliable clamping performance, and consistent operational stability.
The CNC punching line for automotive longitudinal beam flat plates adopts a push-pull clamping arrangement. The clamping mechanism secures the middle sections at both ends of the longitudinal beam. This clamping method ensures reliable fixation of plates with edge-height deviations. The clamping devices are symmetrically positioned on either side of the main machine unit.
At the exhibition, a carefully curated selection of finished longitudinal beam samples—exclusively produced through this production line—is on display. These samples cover an extensive range of specifications customized for mining trucks and special-purpose vehicles. They serve as a persuasive demonstration of the equipment’s core performance capabilities, including accurate hole positioning, smooth punched edges, and the overall structural stability of the finished workpieces.
This flat beam punching equipment line for light trucks is a custom-developed solution, specifically engineered for the punching operation of automotive flat longitudinal beams. It is primarily designed to process the main beams of trucks and special-purpose vehicles, delivering high-precision hole machining to fulfill the structural assembly requirements of these heavy-duty and custom-manufactured automotive load-bearing components.
