Tester di impatto con peso di caduta CNC LC-400 per tubi in plastica

IL Tester di impatto con peso di caduta CNC LC-400 è un'alta precisione, heavy-duty laboratory testing system engineered strictly in accordance with ISO 3127, GB/T 14152, E ASTM D2444 standard. Designed for plastic pipe manufacturers, centri di controllo qualità di terze parti, e materiale R&Istituti D, valuta la resistenza agli urti esterni, tenacità, e comportamento alla frattura dei tubi termoplastici (DN20–DN400mm), fogli, e componenti strutturali sottoposti a impatti di massa di caduta libera standardizzati.

Guidato da un'unità di controllo digitale CNC automatizzata, questo stato dell'arte Tester di impatto del peso di caduta automatizza la calibrazione dell'altezza (500–2000 mm), posizionamento zero automatico, sollevamento del martello, pubblicazione, e cattura dell'impatto secondario antirimbalzo. Costruito con un telaio di guida rigido a doppia colonna e un supporto del provino con blocco a V a 120° (errore di allineamento centrale ≤ 2 mm), l'LC-400 offre un'erogazione di energia a basso attrito e test di impatto altamente ripetibili per il drenaggio in PVC-U, liquami, Tubi in pressione in PE, e sistemi di irrigazione a bassa pressione.

Technological Features of LC-400 Drop Weight Impact Tester

• Automated CNC Height Control & Zero CalibrationFeatures a digital CNC control unit that allows precise presetting of drop heights from 500 mm to 2000 mm. Automated zero calibration and motorized hammer positioning reduce manual setup errors and speed up batch testing.
• Anti-Rebound Secondary Impact Prevention MechanismEquipped with a high-speed mechanical anti-rebound catch system that automatically intercepts the rising strike hammer on its initial rebound, guaranteeing that test results reflect only a single, controlled impact event.
• Stable Dual-Column Guidance Frame (Center Deviation ≤ 2 mm)Constructed with a heavy-duty dual-column support structure that minimizes friction losses during free fall. Ensures precise alignment between the impact centerline and the fixture center (deviation ≤ 2 mm).
• Wide Sample Diameter Range (DN20–DN400 mm) & 120° V-Block FixtureAccommodates pipe outer diameters from 20 mm up to 400 mm via a 0–400 mm adjustable workbench travel. Includes three 120° V-shaped support plates for secure, vibration-free positioning.
• Modular Hammer Heads & Counterweight ConfigurationsSupplied with standard D25 and D90 tup hammer heads (optional SR5–SR30 radii available) alongside interchangeable mass counterweights to meet diverse impact energy criteria across different pipe wall thicknesses.

Architettura del sistema & Testing Workflow of Drop Weight Impact Tester

Flusso di lavoro di test standardizzato:

1. Condition the plastic pipe specimens at the required test temperature (per esempio., 0°C or 23°C) according to ISO 3127 / GB/T 14152.
2. Place the pipe specimen onto the 120° V-block support plates and adjust the workbench travel (0–400mm) to align the pipe center.
3. Select the target hammer head (D25 or D90) and install counterweights matching the required impact mass.
4. Preset the target falling height (500–2000 mm) on the CNC digital control cabinet; the system automatically zero-calibrates and raises the hammer.
5. Initiate the impact drop; the hammer strikes the pipe surface, and the anti-rebound system instantly catches the hammer on its bounce to prevent secondary impacts. Inspect the sample for cracks or penetration.

Applicazioni del cliente target:

Drop Weight Impact Tester FAQ

Q1: How does the secondary impact prevention system work on the LC-400?

UN: Following the initial drop impact, the anti-rebound mechanism automatically catches the rising hammer on its rebound path. This prevents a second strike on the specimen, ensuring test results reflect only a single, controlled impact event.

Q2: What types of plastic pipes can be tested with this equipment?

UN: The system tests rigid PVC (PVC-U) drainage and sewage pipes, low-pressure irrigation pipes, foamed core-layer PVC-U pipes, Tubi in PE, e vari fogli termoplastici con un diametro compreso tra 20 mm e 400 mm.

Q3: Why is a 120° V-block fixture used for pipe impact testing?

UN: Il design con blocco a V a 120° garantisce stabilità, supporto su tre punti su un'ampia gamma di diametri esterni di tubi (Da DN20 a DN400), garantendo che il punto di impatto superiore rimanga centrato direttamente sotto il percorso del martello in caduta con una deviazione inferiore a 2 mm.
