Product Overview
Hydraulic Swing Beam Shearing Machine Overview
A Hydraulic Swing Beam Shearing Machine is a hydraulic metal cutting machine used to produce straight blanks from compatible metal sheet and plate. Hydraulic cylinders move the upper blade beam through a controlled arc while the fixed lower blade provides the opposing cutting edge. The hold-down system stabilizes the workpiece before the cutting stroke, and the back gauge supports repeated blank dimensions.
The source identifies the QC12Y Hydraulic Swing Beam Shear and QC12K Hydraulic Swing Beam Shear as common series and describes an E21S control system for back-gauge positioning. Buyers comparing an NC Hydraulic Swing Beam Shear or CNC Hydraulic Swing Beam Shear should confirm the controller, axes, positioning functions and exact series designation for the selected capacity before ordering.
The published table covers thickness groups from 4 to 40 mm and working lengths from 2500 to 8000 mm under a listed material-strength condition of <=450 kN/cm. These figures do not establish identical capacity for stainless steel, galvanized sheet, aluminum, copper or every grade of carbon steel. Small electric shears suit lighter compact work; a swing beam hydraulic shearing machine is selected when the confirmed material, width or daily output requires greater hydraulic capacity.
Buyer and Production Problems
What Problems Does a Hydraulic Swing Beam Shear Solve?
Sheet Movement During the Stroke
The hydraulic hold-down system secures the sheet before the blade beam moves through the cutting arc.
Repeated Blanks Need Consistent Positioning
The back gauge positions the sheet for repeated cutting lengths within the range published for the selected configuration.
Different Thicknesses Need Suitable Clearance
Adjustable blade clearance allows the cutting setup to be matched to confirmed material thickness and strength.
Swing Beam Cutting Principle
How the Swing Beam Shearing Mechanism Works
The operator first confirms the material, positions the sheet against the squaring reference and sets the required blank length through the configured back-gauge control. The hold-down cylinders then clamp the sheet so it does not shift during the cutting stroke.
Hydraulic cylinders drive the upper blade beam through an arc around its pivot. As the upper blade passes the fixed lower blade, the selected blade clearance and shearing angle allow the cut to progress across the working length. This is swing-beam motion—not the near-linear guided blade-holder movement used by a hydraulic guillotine shear.
After the cut, the nitrogen return system described in the source returns the beam for the next cycle. Cutting frequency, angle, back-gauge travel and motor power vary across the original capacity rows and must be selected from the complete workpiece requirement.
Cutting and Positioning Sequence
From Sheet Positioning to the Swing-Beam Cutting Stroke
01
Confirm the workpiece
Verify material grade, tensile strength, maximum thickness, working length and required cut quantity.
02
Set the back gauge
Enter or adjust the repeated blank length using the confirmed manual, NC or CNC control configuration.
03
Align and hold the sheet
Use the front support and squaring reference; hydraulic hold-down cylinders secure the sheet before cutting.
04
Complete the swing-beam cut
Hydraulic cylinders move the upper blade beam through its arc past the fixed lower blade.
05
Return and continue the batch
The beam returns and the next sheet is positioned for another confirmed cutting cycle.

Machine Selection Comparison
Hydraulic Swing Beam Shear vs Hydraulic Guillotine Shear
Both are hydraulic shearing machines. Select by blade movement, material, thickness, required cutting result, production volume, maintenance capability and budget rather than assuming either design is always better.
| Selection factor | Hydraulic Swing Beam Shear | Hydraulic Guillotine Shear |
|---|---|---|
| Blade movement | Upper blade beam follows an arc around its pivot | Upper blade holder follows near-linear guided movement |
| Machine structure | Practical swing-beam arrangement for economical hydraulic cutting | Rigid guided guillotine arrangement for more demanding work |
| Typical cutting application | Routine sheet and plate blanking in general fabrication | Higher-specification plate cutting where guidance and rigidity are priorities |
| Thickness and accuracy decision | Choose when the confirmed work fits the published swing-beam capacity and tolerance requirement | Consider when material strength, thickness or cutting requirement justifies guillotine guidance |
| Maintenance and investment | Simpler mechanism and value-focused general fabrication profile | More demanding guidance and generally higher configuration level |
| Selection input | Material, thickness, length, daily cuts, tolerance and budget | The same inputs, with extra emphasis on demanding plate and accuracy requirements |
Engineering Selection Guide
How to Choose the Right Hydraulic Shearing Machine
Start with the workpiece and production requirement. The table below identifies when the current swing-beam range is a candidate and when a guillotine or another cutting process should be reviewed.
| Selection factor | Select Swing Beam for Review | Consider Guillotine or Another Process |
|---|---|---|
| Material and strength | The exact grade and tensile strength fit a confirmed swing-beam capacity | Higher-strength material or special edge requirements need a different configuration |
| Thickness and length | Both values match one original 40-row configuration | Required values exceed the table or need different blade-holder behavior |
| Production volume | Routine batch blanking suits the confirmed cutting frequency and handling plan | Higher automation, feeding or demanding continuous duty changes the machine choice |
| Control and positioning | Confirmed NC/CNC controller and back gauge meet repeat-size requirements | More axes, tolerance control or automated handling are required |

Buyer Questions
Hydraulic Swing Beam Shearing Machine FAQ
What is a hydraulic swing beam shearing machine?
It is a hydraulic sheet metal shearing machine whose upper blade beam swings through an arc relative to a fixed lower blade. It produces straight blanks before bending, rolling, welding or assembly.
How does a hydraulic swing beam shear work?
The operator positions the plate against the back gauge, the hold-down system clamps it, and hydraulic cylinders move the upper blade beam through an arc past the fixed lower blade. Selected blade clearance and angle support the confirmed cutting condition.
What is a QC12Y hydraulic swing beam shear?
QC12Y is identified in the source as a common hydraulic swing-beam series. The project also names QC12K and an E21S control system, but exact model-prefix and controller mapping must be confirmed for the selected capacity row.
What materials can a hydraulic swing beam shear cut?
Possible materials include mild steel, carbon steel, stainless steel, galvanized sheet, aluminum, copper and other metal plate. Actual capacity depends on grade, tensile strength, thickness, working length and configuration.
Can it cut stainless steel?
A confirmed stainless grade may be cut within an approved machine capacity, but the published thickness table cannot be applied automatically. Submit the stainless grade, tensile strength, thickness and working length for written confirmation.
What thickness can a hydraulic swing beam shear cut?
The original table lists nominal groups from 4 to 40 mm under a published material-strength condition of <=450 kN/cm. These are not universal limits for every material, and each thickness must be checked with the required cutting length.
What cutting lengths are available?
The source table includes 2500, 3200, 4000, 5000, 6000 and 8000 mm working lengths, but not every thickness is available at every length. Choose an exact row and confirm the machine designation before quotation.
What is the difference between a swing beam shear and a guillotine shear?
A swing beam shear moves the upper blade in an arc and is often selected for economical routine hydraulic blanking. A guillotine shear uses near-linear guided blade-holder movement and may be considered for more demanding plate, rigidity or cutting requirements.
What is the difference between QC12Y and QC12K?
Both designations are named in the source, but the current project does not provide a verified row-by-row definition or controller mapping. NEEDS PRODUCT DATA VERIFICATION: confirm the exact series, controller, axes and back-gauge functions in the quotation.
How do I choose the correct hydraulic shearing machine?
Start with material grade and strength, maximum thickness, cutting length, daily cuts, required tolerance, controller, back gauge, handling method, budget and downstream process. Then compare a confirmed swing-beam row with guillotine and other cutting options.
What information is required for machine selection?
Provide material and grade, tensile strength, normal and maximum thickness, maximum cutting length, required blank sizes, cuts per day, tolerance, preferred controller, back-gauge requirement, voltage, options and destination.
How much does a hydraulic swing beam shearing machine cost?
Hydraulic Swing Beam Shear Price depends on cutting thickness, cutting length, controller, back gauge, hydraulic configuration, optional equipment, voltage, destination and shipping requirements. Request a confirmed quotation when comparing a Hydraulic Swing Beam Shearing Machine for Sale.
