This document is a manual for a patent-style swing arm cutting machine, specifically the TW-510/512/516 A/B/C series. It provides comprehensive information on the machine's operation, maintenance, and troubleshooting.

Function Description

The TW-10/16A/B/C series Rocker Hydraulic Pressure Cutting Machine is designed for cutting various soft materials using a knife die. It serves as a substitute for small-tonnage mechanical cutting machines, addressing issues of loud noise and poor safety properties associated with older models. The machine is primarily used in industries to cut materials such as leather, plastic, canvas, nylon, and cardboard.

Important Technical Specifications

The manual outlines key technical parameters for two main configurations: 100KN/120KN and 160KN.

• Maximum Cutting Force:
  • 100KN/120KN configuration: 100KN/120KN
  • 160KN configuration: 160KN
• Width of Cutting Pressure: 330mm for both configurations.
• Workbench Dimension:
  • 100KN/120KN configuration: 420x750mm
  • 160KN configuration: 420x900mm
• Effective Travel:
  • 100KN/120KN configuration: 50-140mm
  • 160KN configuration: 5-140mm
• Motor Power: 1.5HP for both configurations.
• Overall Dimension (Length x Width x Height):
  • 100KN/120KN configuration: 700x750x1350mm
  • 160KN configuration: 720x900x1350mm
• Hydraulic Oil Amount: 45L for both configurations.
• Net Weight:
  • 100KN/120KN configuration: 430kg
  • 160KN configuration: 500kg
• Gross Weight:
  • 100KN/120KN configuration: 450kg
  • 160KN configuration: 520kg

Usage Features

The machine incorporates several features to enhance its usability, precision, and safety:

• Automatic Lubricant System: Equipped with an automatic lubricant system to reduce wear and prolong service life.
• Electronic Delay Circuit: An electronic delay circuit controls the low limit position of the stroke, ensuring higher precision and cutting quality.
• Adjustable Rocker Arm Height: The height of the working table of the rocker arm can be adjusted using a hand wheel, offering simple, reliable, and convenient operation.
• High-Quality Components: Main key parts, including the main post and the piston of the oil cylinder, are made from high-quality steel.
• Low Energy Consumption: The inertia of the flywheel enables instantaneous cutting with low energy consumption.
• Pump Types: Type A models use a gear pump, while Type B models use a vane pump. Type C models, made in Italy, offer selectable controls for pressure and time.
• Installation Procedure: The manual provides detailed steps for installation, including transporting the machine, cleaning components, adding hydraulic oil, connecting power, and testing motor rotation.
• Operation Order: A clear sequence of operations is provided for cutting, starting with placing materials and the knife die, moving the rocker arm, pressing the descending button, and removing cut materials.
• Safety Precaution: Users are instructed to press the OFF button of the motor when leaving the machine or performing repairs.

Maintenance Features

Regular maintenance is crucial for the machine's longevity and optimal performance:

• Routine Cleaning: The machine requires routine cleaning once per shift and an overall cleaning once per week.
• Oil Filter Cleaning: The oil filter must be cleaned once per month. It is suggested to raise the main post to the maximum position and use compressed air to blow off pollutants from inside to outside during cleaning.
• Hydraulic Oil Level Check: The hydraulic oil level in the machine body must be checked regularly. If it falls below the minimum position, hydraulic oil of the same type should be supplemented. Severe loss requires investigation into the cause and corresponding measures.
• Hydraulic Oil Replacement: Hydraulic oil should be replaced after cumulative 2000 hours of working time or at most once a year. When cleaning the oil tank after the machine stops, it should not be wiped with wool yarn.
• Overflow Valve: The overflow valve is factory-set and locked and should not be adjusted randomly to prevent machine damage due to overload.
• Plastic Backing Plate Usage: To ensure even wear, any position of the plastic backing plate should be used uniformly, and it can be rotated 180° in the horizontal plane.

Troubleshooting and Elimination

The manual includes a comprehensive troubleshooting guide to address common issues:

• Motor Out of Operation:
  • Causes: Disconnected power supply (especially zero line), non-functional contactor of control motor, or damaged startup head (NO) of the motor.
  • Actions: Check power supply line, repair/replace contactor, or repair/replace switch.
• Motor Rotates Reversely:
  • Cause: Two phase lines of the motor are connected reversely.
  • Action: Interchange the external two phase lines of the motor.
• Motor Rotates with Startup Button Pressed, Stops When Released:
  • Cause: Contactor of the motor or its head is broken.
  • Action: Check, repair, or replace the contactor or switch.
• Motor Stops Suddenly During Normal Operation:
  • Cause: Thermal relay is released, and current is overloaded.
  • Action: Check, readjust, or replace the thermal relay.
• Handle Switch Not Pressed, Rocker Arm Descending:
  • Cause: Errors in handle switch and solenoid valve.
  • Action: Check, repair, or replace the handle switch contact and valve.
• Rocker Arm Cannot Descend When Handle Switch is Pressed:
  • Causes: Error in manual switch, insufficient oil in the tank, leakage in hydraulic oil pipe or joint, loose relief valve, switches not pressed synchronously, non-functional solenoid valve, or broken/worn seal ring in the oil cylinder.
  • Actions: Check/repair/replace manual switch, add hydraulic oil, check/eliminate leaks, readjust relief valve, press switches synchronously, check electromagnet/wires, or check/eliminate faults in seal ring/oil cylinder.
• Blanking of Rocker Arm Not Cut Off:
  • Causes: Delay timer not matching travel distance, leakage/insufficient oil in oil cylinder, or blocked oil filter.
  • Actions: Readjust delay timer. If the issue persists, check/repair relief valve, oil cylinder, piston, and oil filter.
• Blanking Cut Off, But Cutting Depth Too Large, Motor Rotates Slowly/Stops:
  • Causes: Delay time is too long, relief valve is loose (low overflowed liquid pressure), or solenoid valve cannot be reset.
  • Actions: Reset to a shorter delay time, readjust pressure, or repair/replace solenoid valve.
• Rocker Arm Cannot Be Reset After Descending:
  • Causes: Solenoid valve cannot be reset, or piston and piston rod are loose.
  • Actions: Repair/replace solenoid valve, or disassemble/repair piston and piston rod.

Warranty Information

The machine comes with a one-year guarantee for the whole machine and its main components. Warranty claims require a valid invoice and a complete guarantee repair list. The warranty is void if the invoice or repair list is altered, the machine number is modified, or if damage is caused by improper operation, maintenance, storage, non-specific maintenance, or force majeure.
