Hydraulic Shearing Machine

Hydraulic Shearing Machine

The hydraulic shearing mchine also called cutting machine, which is suitable for cutting gold or silver ingots.

The machine consists of a frame, cutting unit, feeding device, hydraulic system, and electrical control system.

The machine uses a hydraulic shearing method for cutting. The cutting unit is mounted on the frame and includes an upper cutting blade and a lower cutting blade with guide grooves. Below the cutting blade is a square hole for the cut fragments to slide down into a collection bin.

Operation Process:

Place the material to be cut into the feeding slot.

Press the automatic cutting button, and the feeding cylinder pushes the ingot toward the cutting frame.

Once the desired cutting length is reached, the feeding stops.

The clamping device secures the ingot in place.

The cutting blade descends to shear the ingot.

The cut material falls into the collection bin under its own weight.

After cutting, the system automatically resets, and the feeding device advances the material for the next cut.

Adjustable Features:

The cutting length can be customized as needed.

The cutting blade is a tough-edge shear blade (flat-edge design).

To reduce shear force, the upper blade is designed with a slight bevel angle, which minimizes stress on the blade and extends its service life.

Q1：Why is the machine equipped with an automatic feeding system

• Enhanced Safety

Reduced Operator Risk: During the cutting process (especially during hydraulic blade descent), the automatic feeding system eliminates the need for manual material handling near the shear zone.

Programmed Sequence Reliability: The system’s pre-defined action sequence (e.g., clamping before cutting) eliminates equipment damage or accidents caused by human operational errors.

• Guaranteed Cutting Precision & Consistency

Precision Length Control: The feeding cylinder’s stroke is precisely regulated via pre-set cutting lengths, avoiding manual measurement errors and ensuring uniform material lengths.

Anti-Slippage Mechanism: The synchronized operation of the feeding system and clamping device (e.g., immediate clamping after feeding stops) prevents material slippage or misalignment, ensuring clean cuts.

• Improved Production Efficiency

Continuous Operation: Program-controlled feeding (advance, stop, reset) eliminates the need for manual feeding, reducing downtime between cutting cycles and boosting throughput.

• Reduced Labor Costs & Operational Strain

Minimal Human Intervention: Operators only need to load raw materials and set parameters, making it ideal for prolonged, high-intensity operations.

• Minimized Material Waste

Optimal Material Utilization: Cylinder stroke precision avoids over-cutting or under-cutting, reducing excess material waste.

Debris Management: Cut fragments directly slide into a collection bin via the square hole, while automatic feeding clears the workspace, preventing debris accumulation that could compromise subsequent cutting accuracy.

Q2: Can the same machine cut three different sizes of gold ingots?

Yes, the same machine can be used. The hydraulic cylinder controls the blade’s pressing stroke. To adapt it for three sizes, we need:

Key Parameters:

Maximum & minimum thickness of the client’s ingots.

Maximum width of the ingots.

Customization:

Three interchangeable pressure blocks (matched to ingot dimensions) are installed to accommodate varying sizes on the same machine.

How It Works:

The pressure blocks ensure proper clamping force and alignment for different ingot dimensions.

Hydraulic stroke adjustment allows precise blade positioning across thickness ranges.

Q3: Why is clamping required before cutting in the automated workflow (Feeding → Positioning → Clamping → Cutting → Reset)?

Even though the bevel angle design of the upper blade disperses shear forces, the material must remain rigidly fixed during cutting. Here’s why clamping is critical:

Preventing Material Displacement:

The automatic feeding system ensures precise positioning and clamping, eliminating material movement during shearing.

Avoids uneven force distribution that could cause abnormal blade wear or edge chipping.

Reducing Impact Load:

Stable feeding and cutting rhythms minimize shock loads on the blade.

Combined with the bevel angle’s mechanical advantage, this synergy significantly extends the blade’s service life.

Optimized Cutting Accuracy:

Clamping prevents micro-slippage, ensuring clean cuts and consistent product dimensions.

Q4: In the production of precious metals, under what circumstances is a shearing machine needed?

If a customer wants to make a large gold or silver ingot (12.5kg) into a small gold or silver bar (for example, 1kg), the shearing machine can cut the gold or silver ingot into small pieces, which can speed up the melting process and save electricity. Then the small gold and silver bars are put into the granulator to make gold and silver grains for easy weighing, and then dried. Then the dried gold and silver grains are put into the vacuum gold/silver bar casting machine to make gold and silver bars. Then the gold bars are marked and coded by the hydraulic press machine and marking machine.
