Introduction

The full automatic serpentine tube bender delivers complete inline automated bending of single stainless steel tubes. It integrates the entire process spanning decoiling, straightening, cutting, bending, and recoiling finished pipes in one interlinked sequence. Compared to manual bending methods, this smart tube bending machine achieves exponential gains in throughput and precision while minimizing labor costs.


Machine Architecture

The bender features an all-welded steel frame and base for stability. The modular construction allows easy access and maintenance. Industrial-grade coating on all parts enhances durability. Critical components are sourced from reputable brands to ensure precision capabilities.


The servo-electric architecture with distributed control and smart instrumented actuators allows advanced movement coordination and adaptive bending. The centralized PLC orchestrates the sequential actions based on sensor feedback and operator inputs through the HMI.

Features

Precision Three-Part Tube Clamping System:

The bender utilizes a three-piece collet or clamping system consisting of the headstock, bend die, and clamping pressure pads. This securely holds even thin-walled tubes up to 110 bend cycles without deforming or collapsing the material, ensuring pristine bends.


High Accuracy Rotational Positioning:

The servo-electric bend system rotates the tube incredibly accurately to any angle between 0 to 360 degrees during bending. The precise rotary positioning minimizes twisting and ensures straightness for superior weld seam quality in subsequent fabrication processes.


Chipless Shear Cutting:

The pneumatic cutting mechanism uses two-point tube clamping and a stretching tension strategy to deliver chipless cuts in one quick shear motion. This produces clean-cut ends without burrs or debris.


Patented Advanced Servo Bending Control:

The programmable servomotors drive the bending axes to make exact angle bends (1-180°) with extreme repeatability within 0.1°. Custom tool profiles create precise bending radii (R35-R50) without wrinkling or marring. (ZL 2011 1 0092227. X)


Customized Bend Tooling System:

Patent-protected bending tools are engineered specifically for stainless tubes. The machined grooves ensure controlled flow without surface damage, even on thin tubes or tight radii.  (ZL 2011 2 0107426.9)


Simultaneous Multi-Tube Handling:

A specialized rotating structure provides enhanced stability for concurrently bending multiple pre-aligned tube groups in one cycle for high productivity. (ZL 2009 2 0013741.8)


Smart Automation Architecture:

The servomotors, PLC system, industrial-rated HMI touchscreen, and proprietary software automate each sequence - straighten, move, cut, clamp, bend, and unload – for reliable walk-away 24/7 functioning.  Alarms indicate faults.


The combined precision hardware components, custom bending tools, and automation capabilities deliver high-efficiency, single-tube serpentine bending for manufacturing applications.
