PLC-Controlled Hydraulic Scrap Metal Shear with Water-Cooled Power System

SEO Title: PLC-Controlled Hydraulic Scrap Shear with Water Cooling
Meta Description: The Q91Y-630W features Omron PLC control, remote operation, three 45kW motors, A4V-250 pumps, and a hydraulic water-cooling system.

Integrated Control for Heavy Scrap Processing

The Q91Y-630W PLC-controlled hydraulic scrap metal shear combines hydraulic cutting, material holding, rear pushing, and length adjustment within one control system.

The supplied specification identifies an Omron CP1E-series PLC, XINJIE text display, Omron limit switches, Delixi electrical components, and Yicheng solenoid valves.

The machine also supports remote-control operation, allowing relevant movements to be controlled from a suitable operating position.

Main Hydraulic Power Configuration

The machine uses three main electric motors.

The hydraulic system is driven by three A4V-250 pumps.

The documented hydraulic-system working pressure is no more than 25MPa. The 31.5MPa figure refers to the pump’s rated pressure and should not be presented as the normal operating pressure.

Water-Cooling Circulation

Hydraulic shearing places a continuous load on the oil system. The Q91Y-630W includes a water-cooling circulation unit.

Its cooling configuration includes:

• 65-125A-2.2 circulation pump
• 2.2kW pump power
• 1450rpm rated speed
• 200L/min nominal flow
• 0.63MPa nominal pressure
• BB60H-20 water cooler

The total installed system power is listed as 137.2kW, combining the three 45kW main motors with the 2.2kW cooling pump.

Coordinated Machine Movements

The control system manages several hydraulic actions:

1. Rear-cylinder material feeding
2. Material-length positioning
3. Hydraulic holding
4. Shearing-cylinder movement
5. Cylinder return
6. Repeated cutting sequence

This coordinated operation is more suitable for industrial scrap processing than equipment that requires each movement to be controlled independently.

The document supports PLC and remote-control operation, but it does not describe the system as a fully unmanned automatic line.

Electrical Customization

The standard electrical specification is:

380V, three-phase, 50Hz

The document states that other power specifications can be customized. Customers should provide local voltage, frequency, phase requirements, and applicable electrical standards before production.

Suitable Users

This configuration is relevant to:

• Scrap recycling yards
• Steel mills
• Foundries
• Steel fabrication plants
• Industrial metal recovery facilities

The PLC system, remote control, hydraulic power unit, and cooling circuit work together to support repeated heavy scrap cutting. Machine selection should still be based on material size, steel strength, loading method, and required processing capacity.
