Hydraulic swing beam shearing machine (QC12Y series)

In modern metal fabrication, cutting accuracy is an important part of the overall production process. Whether manufacturers are processing steel plates, stainless steel sheets, or other metal materials, the shearing machine needs to provide stable cutting performance while keeping setup time and operator workload under control.

A CNC hydraulic shearing machine combines a rigid machine structure, hydraulic power, automatic positioning, programmable control, and multiple safety functions to create a practical solution for repeated sheet-metal cutting operations.

Instead of relying entirely on manual adjustments, the machine can automatically manage important cutting parameters and execute programmed production steps. This makes it particularly useful for workshops that need consistent results across different batches and workpieces.

Rigid Welded Construction for Stable Operation

The machine body is completely welded from steel plates, creating a firm and rigid structure.

For a shearing machine, structural rigidity is important because cutting generates significant mechanical forces. If the machine frame is not sufficiently stable, vibration and deformation can affect cutting accuracy and blade performance.

A welded steel-plate construction provides a solid foundation for the hydraulic and CNC systems. It also helps the machine maintain stable operation during repeated cutting cycles.

For production environments where the machine is expected to operate continuously, structural stability can directly influence long-term reliability.

Front Supports Help Position Workpieces

Handling large or heavy metal sheets can be challenging when operators need to maintain accurate positioning manually.

The front supports are designed to help hold and measure workpieces before cutting. This can make material positioning more convenient and reduce the amount of manual handling required during preparation.

For workshops processing sheets with different dimensions, front support equipment can also make repeated cutting operations easier to organize.

Depending on the production configuration, the machine can also be equipped with a pneumatic piece receiver. This additional function can help manage the cut material after the shearing operation.

Strong Hydraulic Power for Consistent Cutting

Hydraulic power is at the center of the machine's cutting operation.

A strong hydraulic pump provides the force required to drive the cutting system through metal sheets. Compared with manually operated cutting equipment, hydraulic operation provides a controlled power source that is suitable for demanding production environments.

Hydraulic systems also allow the cutting process to be integrated with CNC control. This means the machine can coordinate positioning, cutting cycles, and other parameters as part of a programmed operation.

Hydraulic Overload Protection

Protection against overload is another important consideration for industrial shearing equipment.

During metal cutting, excessive loads can occur if the material is unsuitable for the machine, the thickness exceeds the intended range, or abnormal operating conditions occur.

The hydraulic overload protection system is designed to help protect the machine when excessive hydraulic pressure or load conditions are encountered.

This type of protection can contribute to longer component service life and reduce the risk of damage caused by abnormal operating conditions.

Operators should still follow the manufacturer's recommended material thickness, grade, blade specifications, and operating procedures.

CNC Control Simplifies Repeated Production

One of the most useful features of the machine is its CNC-controlled system.

The controller can store up to 100 programs, while each program can contain up to 20 work steps.

This provides considerable flexibility for workshops that regularly process different sheet sizes or cutting patterns.

Instead of manually entering the same parameters for every batch, operators can select the appropriate stored program and allow the CNC system to execute the predefined sequence.

This is particularly useful for:

• Repeated production orders

• Multiple sheet sizes

• Different cutting lengths

• Batch processing

• Standardized manufacturing procedures

• Small- and medium-volume production

Program storage can also help reduce setup errors when the same products need to be manufactured repeatedly.

5.7-Inch LCD Touch Screen

The machine uses a 5.7-inch LCD touch screen as the operator interface.

A touch-screen control system provides a more direct way to interact with machine settings and stored programs. Operators can access the relevant parameters without relying entirely on manual mechanical adjustments.

For production environments with multiple operators, a centralized digital interface can also make machine operation easier to standardize.

The control system is designed to bring important machine functions together, allowing operators to manage the cutting process from one interface.

Automatic Back-Gauge Adjustment

Back-gauge positioning has a direct influence on cutting length and repeatability.

On a conventional machine, operators may need to make repeated manual adjustments to position the material correctly. The CNC system can automatically adjust the back gauge according to the programmed cutting requirements.

This reduces setup work and helps maintain consistency between individual workpieces.

For batch production, automatic back-gauge adjustment can be particularly valuable because the machine can repeat the same positioning sequence without requiring the operator to manually measure each piece.

Automatic Blade Gap Adjustment

Different material thicknesses can require different blade-gap settings.

If the gap is not properly adjusted, cutting quality may be affected and unnecessary stress can be placed on the blades and machine components.

The CNC system can automatically adjust the blade gap according to the programmed cutting conditions.

This helps reduce manual setup operations and makes it easier to switch between different workpiece specifications.

Automatic blade-gap adjustment is especially useful for workshops that process a variety of sheet thicknesses during the same production period.

Automatic Cutting Times

The machine can also automatically manage the number of cutting cycles.

This function is useful when a production order requires repeated cuts of the same specification. Once the required cutting sequence is programmed, the machine can execute the planned number of cycles without requiring the operator to initiate every individual cut manually.

Combined with automatic back-gauge and blade-gap adjustment, this creates a more coordinated cutting workflow.

Error Alarm Function

Industrial equipment needs to provide clear feedback when an operating error or abnormal condition occurs.

The CNC system includes an error alarm function designed to alert the operator when a problem is detected.

An effective alarm system can help operators identify abnormal conditions earlier and take corrective action before the problem affects a larger production batch.

This can also simplify routine troubleshooting and reduce unnecessary downtime.

Foot Pedal With Emergency Stop

Operator safety is an essential consideration in sheet-metal processing.

The machine is equipped with a foot pedal for convenient control of the cutting operation. The pedal also incorporates an emergency-stop function.

This provides the operator with an accessible way to stop the machine when an emergency situation occurs.

Safety functions should always be used together with proper operator training, machine guarding, maintenance procedures, and workplace safety requirements.

A Practical Solution for Modern Sheet-Metal Workshops

The combination of a rigid welded structure, strong hydraulic power, CNC programming, automatic positioning, blade-gap adjustment, overload protection, and safety functions makes this type of hydraulic shearing machine suitable for a wide range of sheet-metal processing environments.

Its programmable CNC system can store 100 programs with up to 20 work steps per program, allowing manufacturers to manage different production requirements more efficiently.

Automatic adjustment of the back gauge, blade gap, and cutting times can reduce repetitive manual operations, while front supports and optional pneumatic material receiving equipment can improve material handling.

For workshops looking to improve cutting consistency and reduce setup work, a CNC hydraulic shearing machine provides a practical combination of mechanical strength, hydraulic power, digital control, and production automation.
