Product Description

Long Aluminum Billet Multi-Saw Cutting Line

This multi-saw production line performs fully-automated cutting for full-series aluminum alloy long billets. It covers cropping of billet heads, fixed-length cutting, tail separation and swarf collection, serving as pre-processing equipment for extrusion workshops.

Machine Composition

The complete line consists of buffer-alignment station, multi-billet loader, in-feed conveyor, main multi-saw unit, out-feed conveyor, length-gauge unit, output rack, cropping scrap bin, aluminum swarf recovery system, hydraulic power pack and PLC-based electrical control system.

Working Process

Overhead crane transfers aluminum billets from casting pit onto buffer-alignment table for end-face alignment.
Multi-billet loader lifts and shifts multiple billets onto the in-feed roller track.
Rollers feed billets to main saw station; workpieces are clamped before head cropping.
Billets travel to length-gauge unit. After target dimension setting, clamping triggers tail cropping.
Cropped heads and tails drop into scrap bins by gravity. Aluminum swarf is gathered by fan-driven collection unit.
Finished billets are transferred to output rack for crane removal.

Controlled by PLC, all process values are digitally entered via HMI. Built-in fault alarm and safety interlock functions. Manual / automatic dual operating modes are available.

Major Modules, Materials & Standards

Reliability basis: steel grades, national & industry standards and key component suppliers are documented for technical reference.

Loading Platform & Multi-Billet Loader

Loading platform assemblies: Q235B rectangular steel tube 250*150*8 (Shaoguan Iron & Steel), chain-driven design for 6.5 m billets, 2 sets.
U-shape manipulator for lifting & traversing loading: 1 set.
Driven by RCW87 geared motor, double-row sprocket-chain and 2-inch carrier chain.
HOB-series hydraulic cylinders (Foshan Jialida, complying with GB2348-2001) for billet lifting & feeding.

In-feed Section

Frame: GB standard hot-rolled 20# channel steel per GB/T706-2008 (Shaoguan Iron & Steel), dimension 12000*710*800 mm.
Rollers: 45# carbon steel; HRB 6210 bearings.
Drive: BMR-200 4-port hydraulic motor conforming to JB/T10829-2008 drives roller-chain conveying system.

Main Saw Unit

Horizontal circular saw configuration. Saw head advance-retreat driven by hydraulic cylinder-motor with adjustable feed speed. Equipped with quasi-dry mist lubrication assembly.

Saw-head frame: Q235B square tube 100*100*5.
TCT saw blade ∅900 mm, 72 teeth; 45 kW saw motor.
Quenched-and-tempered 45# steel spindle, imported FKG 6315 spindle bearings.
Vertical clamping cylinders, head-aligning cylinder, HOB feed cylinder; guide-rod & bronze bushing set ensures linear travel accuracy of saw carriage.

Out-feed & Length-Gauge Assembly

Out-feed frame: GB-grade 20# channel steel. Integrated length-gauge unit with sensor-based buffer anti-collision function.
Rollers driven by BMR-200 hydraulic motor for post-cut handling. Out-feed hydraulic cylinders perform unloading movements.

Hydraulic Power Pack

One shared hydraulic station for the whole production line. Welded reservoir of Q235B steel plate; PV2R21 oil pumps and manifold valve blocks. Air-cooled heat exchanger (non-water-cooled), suitable for plants with limited or poor-quality water supply.

Scrap & Swarf Handling

Billet heads/tails fall by gravity into welded scrap bins.
Aluminum swarf: fan suction into sealed housing, with swarf compacting station for convenient waste transportation.

Electrical Control System

Control core: Mitsubishi PLC 128M + Weinview 7-inch HMI touch-screen.
Components: Schneider contactors & thermal relays, Chint circuit breakers, proximity sensors, photo-electric and limit switches.
Main electrical cabinet plus separate operation console, full set of cables, cable ducts and terminal blocks.
Functions: fault alarm and safety interlock protection.

Operation Notes for Selection

This line is designed exclusively for long aluminum billet cropping, not for other non-ferrous metals or profiles.
Site requirements: 3-phase 380 V power supply and stable compressed air ≥0.6 MPa.
Vegetable-based cutting oil is required for mist lubrication; customer shall provide oil replenishment.
Noise level <160 dB(A) measured at 2 m distance. Noise-reduction protection shall be arranged in production workshop.
