Features of TT-PCD450J Digital Pendulum Impact Tester
- Monolithic Frame & Base
Monolithic cast (HT250) and machined design eliminates weak points of frame base which improves the overall rigidity, stability, and test consistency. It minimizes the energy absorption which are ideal for high energy impact.
- Minimizing Assembly Errors
The machine monolithic construction avoids alignment errors which are usually found in bolted frame/base structures.
- Firm and Rigid Design
All the load-bearing components are designed using Finite Element Analysis (FEA) that are carefully machined and tested.
- Precise Machining
The CNC machining center ensures precise one-time machining of front/rear bearing bores and anvil mounting positions. It guarantees symmetry of bearing bores and accurate distance from pendulum axis to striking point.
- Dual-Support Frame
Supported beam pendulum shaft minimizes the lateral pendulum vibration during impact.
- Balanced Bearing Load and High-Precision Bearings
It equalizes the force distribution on front/rear pendulum bearings, reducing the friction and minimizing impact damage to bearings. With its imported bearings, it offers low friction, high impact resistance, and long service life.
- Optimized Pendulum and Stiff Pendulum Rod
The pendulum hammer (circular) is carefully designed using 3D CAD for precise center of gravity. Circular shape effectively reduces air drag energy losses during swing. While the rod is thick-walled seamless tubing that ensures high rigidity, no deformation, reducing energy absorption.
- Special Striking Edge and Interchangeable Edges
Made from special high-hardness material, minimizing deformation and resisting impact damage. It includes both 2mm and 8mm striking edges. Screw-clamping mechanism allows for simple and convenient edge changes.
- Durable Anvils
Anvils (specimen supports) made from special materials/processes ensure robust, rounded edges, smooth transitions between planes and arcs, with high impact/wear resistance.
- Powerful Lift Motor and Advanced Electromagnetic Clutch
Dual-stage geared motor provides high torque for reliable pendulum lifting without slippage and low noise. Gear motor manufactured using German technology ensures reliable, long-lasting performance. The Imported clutch technology ensures rapid engagement/disengagement without slippage.
- Reliable Programmable Logic Controller (PLC)
Automates the entire test cycle (lifting, latching, releasing/impact, braking/positioning), minimizing electrical failures.
- Precise Latching Angle
PLC-controlled latching ensures consistent, preset lift angle, guaranteeing constant initial impact energy.
- Hydraulic Latch Buffer
Hydraulic buffer mechanism ensures smooth, vibration-free latching, protecting the latch/release mechanism from impact damage.
- Electromagnetic Release and Automatic Re-latching
Electric release ensures clean, consistent pendulum drop, maintaining specified initial impact energy and velocity while automatic re-latching utilizes residual energy post-impact to automatically re-latch the pendulum, preparing for the next test and improving efficiency.
- Scalability Energy
Initial energy level can be adjusted by changing the pendulum hammer, extending the machine’s application range.
