DW38CNC‑3A‑1S Fully‑Automatic CNC Tube Bending Machine

제품 설명

Pipe bender machine Main Technical Specifications

주요 기능

1. 3‑axis full‑servo control: Servo motors handle feeding, tube rotation and bending angle for repeatable precision in batch production.
2. Flexible programming: Support YBC bending‑coordinate input and XYZ‑to‑YBC automatic conversion; easy for new operators to learn.
3. Mandrel / mandrel‑free bending: Selectable mandrel structure to avoid tube wrinkling or flattening for thin‑wall tubes.
4. Automatic anti‑collision protection: Real‑time position monitoring reduces crash risks during continuous automatic cycles.
5. Large program memory: Save hundreds of product recipes for fast job switching without repeated parameter setup.
6. Wide material compatibility: Process round tube, square tube and special‑section metal profiles by changing tooling sets.
7. Expandable options: Compatible with push‑bending attachment, auto‑loader, remote technical support interface.

Note: All parameters are for reference; actual performance depends on tube material, wall thickness and tooling configuration.

Q1: What does model code DW38CNC‑3A‑1S mean?

A:

• DW: Tube bending machine series
• 38: Maximum tube outer diameter 38 mm
• CNC: Computer numerical control
• 3A: 3 servo‑controlled axes (X‑feeding, C‑tube rotation, B‑bending rotation)
• 1S: One‑layer mould station, hydraulic clamping system.

Q2: What tube sizes and materials can this machine process?

A: Max capacity: Φ38 mm × 2.0 mm for carbon steel. It works for round tube, square tube and special‑shaped profiles. Applicable materials include carbon steel, stainless steel, copper and alloy tubes. Actual capacity depends on material hardness and wall‑thickness.

Q3: What is the minimum bend radius?

A: Standard minimum bend radius ≥1.5D (D = tube outer diameter). Tighter radius is possible upon special tooling request, but thin‑wall tubes require mandrel and wiper die to avoid wrinkling or collapsing.

Q4: What programming modes are supported?

A: Two programming options:

1. Direct Y‑B‑C parameter input (bending angle, rotation angle, feeding length).
2. X‑Y‑Z 3D coordinate input; system auto‑converts to Y‑B‑C data.

   Up to 500 sets of bending programs can be stored for quick job change‑over.

Q5: Does this machine support mandrel bending and mandrel‑free bending?

A: Yes. Mandrel assembly is optional. Use mandrel for thin‑wall tubes to prevent tube wrinkling and oval deformation. Mandrel‑free mode applies for thick‑wall tubes onlyShenglida ….

Q6: What are the positioning accuracies?

A:

‑ Bending angle accuracy: ±0.1°

‑ Tube rotation accuracy: ±0.1°

‑ Feeding positioning accuracy: ±0.1 mm.

Q7: What is the maximum feeding stroke?

A: Standard feeding stroke is 2200 mm; customized longer stroke is available as option.

Q8: Can I bend square tubes with this machine?

A: Yes. You need to purchase corresponding square‑tube mould sets. The machine itself is compatible, tooling is sold separately.

Q9: What power supply does the machine require?

A: Standard 3‑phase 380V / 50Hz. Custom voltage (415V, 220V 3‑phase etc.) can be configured for different countries.

Q10: What optional accessories are available?

A: Mandrel assembly, wiper die set, push‑bending module, auto‑loading device, remote diagnosis module, customized moulds.

Q11: Why does spring‑back happen during tube bending?

A: Metal material will spring back after cold bending. You can set spring‑back compensation value in HMI system to offset angle deviation. Trial bending is recommended for new material batches.

Q12: Is anti‑collision function included?

A: Yes. Built‑in anti‑collision detection monitors axis positions in automatic cycle to avoid mechanical crash. Emergency‑stop button and safety interlock are also equipped.

Q13: What after‑sales warranty do you provide?

A: 1‑year warranty for mechanical parts (excluding consumable moulds and mandrel). Remote technical support is available. Spare parts can be supplied at cost price after warranty expires.

Q14: Can the system language be changed?

A: Yes, multi‑language support (English, Chinese and others). Language can be switched on touch‑screen HMI.

Q15: What is the delivery time?

A: Standard model: 15‑25 working days. Customized configuration will need longer lead‑time.
