Key Features

Equipment Introduction

1.Automatic material machine

Function: used to support the unwinding of coils.
Main structure: frame, expansion assembly, spindle, support arm assembly, hydraulic assembly, electric part, etc.
Frame: welded by ordinary carbon steel plate and square tube, and the spindle and two bearing seats are welded in series at one time to ensure the concentricity of the spindle.
Expansion assembly: Expansion range diameter: Φ470mm～Φ530mm, maximum width 1300mm, maximum outer diameter Φ1500mm. Four arc plates are connected to the main shaft by sliders for sliding expansion.
Main shaft: Made of 45# round steel, quenched and tempered, fine-turned, with a load-bearing capacity of 15 tons.
Pressing arm assembly: Used to press the material to the looseness of the coil, and to assist the material feeding to the leveling feeder.
Hydraulic power: push-pull expansion and contraction mandrel.
Electrical power: frequency converter speed regulation, 11KW motor with pendulum gear reducer with chain drive.

2、Leveling and feeding machine

Function: used for leveling materials and feeding materials of fixed length.
Main structure: leveling roller, electric part, inlet and outlet support seat assembly.
Leveling roller: made of 40Cr round steel after tempering and high-frequency processing, after two electroplating and external cylindrical grinding, the surface is shiny and has no traces, and the hardness reaches HRC62 degrees or more.
Back pressure roller: made of 40Cr round steel after tempering and high-frequency processing, after two electroplating and external cylindrical grinding, the surface is shiny and has no traces, and the hardness reaches HRC62 degrees or more.
Feeding roller: made of 40Cr round steel after tempering and high-frequency processing, after two electroplating and external cylindrical grinding, the surface is shiny and has no traces, and the hardness reaches HRC62 degrees or more, and the above adopts pneumatic relaxation.

3、Pneumatic clutch shearing machine

This machine tool has changed the transmission form of mechanical shearing machines and is currently recognized as one of the most advanced small shearing machines at home and abroad. This machine absorbs foreign advanced technology and adopts pneumatic clutch and flywheel. Its transmission mode is driven by the motor to drive the flywheel, which is instantaneously engaged under the control of the selective foot switch. The small shearing angle and inclined shearing direction reduce the bending deformation of the workpiece to a minimum. The blade gap is adjusted by a manual quick adjustment device, which is very easy to obtain a satisfactory blade gap. It is an ideal processing and shearing equipment for metal and non-metal plates.

 4、 Conveyor

5、Open fixed stacking lift

Frame: Made of carbon steel welded, stable and firm. Scissor-type design, hydraulic cylinder lifting and lowering.
1）The platform has a material blocking plate and a material knocking plate.
2) Manual movement to adjust the material width, pneumatic material knocking.

I. Daily Maintenance (Daily/Per Shift)

1. Lubrication & Water Drainage

   • Gears & Bearings: Use the grease gun to apply gear grease.

   • Water Removal:

     • Three-point assembly: Press or turn the drain button under the water-collection bucket.

     • Air receiver tank: Open the drain valve to expel accumulated water.

2. Roller Cleaning

   • Remove any foreign matter between the upper and lower feed rollers; ensure they close fully and uniformly.

3. Oil & Air Pressure Check

   • Verify gauges (both pressure dial and visual indicator) show normal readings.

   • Listen and sniff for any leaks in the system.

4. Fastener Inspection

   • Check all screws and nuts across mechanisms for tightness; retorque as needed.

5. Control Panel & Indicators

   • Confirm switches, indicator lights, and displays function correctly.

   • Keep the human-machine interface clean and free of dust or oil.

II. Periodic Inspection (Every 6 Months or 1,000 Hours)

1. Electrical System

   • Inspect external power cables for deformation, wear, aging, or signs of leakage/short-circuit.

   • In the control cabinet, check relay contacts and timing-cam switch for contact wear or oil contamination.

2. Panel Switches & Buttons

   • Test tactile feel, travel, and contact performance of each button.

   • Verify the timer device (timer) operates accurately.

3. Hydraulic Piping

   • Examine all high-pressure hoses and fittings for cracks or seepage.

   • Check hydraulic tank oil level and fluid condition.

III. NC Servo System

• Maintain a dust-free, non-corrosive environment; keep ambient and heatsink temperatures within specified limits; ensure cooling fans run properly.

• Inspect servo-motor cable connections for looseness and verify insulation integrity.

IV. Component-Specific Care

V. Three-Color Warning Tower

• Green: Normal operation (servo advance/retreat, single-step or auto feed modes ready).

• Yellow: Feed station on standby (servo ready, feed mode not active).

• Red + Buzzer: Emergency stop or fault — immediately halt production and troubleshoot.

Tips for Effective Maintenance:

• Keep synchronized paper and electronic maintenance logs.

• After each task, record the date, technician, and any issues found.

• If you detect unusual noise, vibration, or abnormal readings, stop immediately and resolve the root cause before resuming.
