Key Features of High-Quality Solor Strut Roll Forming Machines

Core advantages of the high-speed photovoltaic mounting frame forming machine

Profile Deformation & Dimensional Errors

Issue 1: Twisting, Curving & Tracking Deviation

Causes

Uneven roll gap on left and right sides.

Misaligned feeding center of the leveling machine.

Loose anchor bolts causing frame vibration at high speed.

Improper deformation distribution among forming passes, leading to residual stress.

Excessive clearance of roller bearings.

Solutions

Adjust roll gaps symmetrically with feeler gauges to ensure equal pressure on both sides.

Align the whole line to keep steel strip moving straight without lateral shift.

Level the main frame and fasten all foundation bolts to eliminate vibration.

Distribute bending deformation into multiple passes to reduce springback.

Replace worn bearings to stop roller shaking.

Issue 2: Out-of-tolerance Dimensions (Flange Height, Opening Width, Angle Springback)

Causes

Worn forming rollers.

Uneven thickness of incoming galvanized coils.

Excessive or insufficient roll pressing depth.

Q355 high-tensile steel has larger springback than ordinary carbon steel.

Solutions

Polish or replace damaged rollers.

Reject raw materials with big thickness deviation.

Fine-tune roll pressure step by step with multi-pass forming.

Reserve extra compensation angle for high-strength steel to counter springback.

Issue 3: Edge Wave & Wrinkle

Cause

Over-bending at edge positions and unstable strip tension. 

Solution

Divide edge bending into more forming stations, keep consistent feeding tension and remove burrs on rollers.

Issue 4: Surface Scratches on Galvanized Strip

Cause

Sharp edges on rollers and guide plates. 

Solution

Polish all contact parts; install nylon anti-scratch guards to avoid hard friction.

Punching System Failures

Hole Pitch Deviation & Poor Position Accuracy

Causes

Servo encoder drift; wrong PLC timing parameters; unstable feeding speed. 

Solutions

Recalibrate encoder; reset punching program; stabilize line speed; synchronize hydraulic punching action.

Big Burrs, Cracked Steel & Broken Punches

Causes

Excessive gap between punch and die; dull cutting edges; over-high hydraulic pressure. 

Solutions

Control die clearance within 8%~10% of sheet thickness; regrind tool edges; reduce hydraulic pressure properly.

Missing Punching & Continuous Punching

Check photo sensors and proximity switches; remove oil contamination; re-match feeding and punching timing.

Flying Shear & Cutting Troubles

Length Inaccuracy

Causes

Slipping encoder; lost servo parameters; strip slipping during transportation. 

Solutions

Lock encoder shaft; reset flying shear parameters; tighten feeding pinch rollers to prevent material sliding.

Uneven Cuts & Distorted End Profiles

Replace blunt cutting blades and adjust blade clearance evenly; add material supports under the profile to reduce bending during cutting.

High Hydraulic Oil Temperature & Jumping Shear

Clean water cooling pipeline; replace hydraulic oil regularly; avoid non-stop high-speed operation without heat dissipation.

Feeding & Mechanical Malfunctions

Material Jamming

Reduce pressure of leveling rollers; install coil straightener to correct strip camber; re-align the whole production line.

Excessive Vibration & Abnormal Noise

Lubricate bearings and gearboxes regularly; tighten chains and transmission parts; replace worn gears.

Servo Alarm & Automatic Shutdown

Stabilize three-phase power supply; check loose wiring; lower instantaneous line speed to cancel overload protection.

Routine Maintenance Tips

Clean rollers and punching dies every shift;

Refill lubricant for bearings and reducers daily;

Re-calibrate center line, roll gap and punching timing every two weeks;

Keep hydraulic water cooling system running continuously during mass production;

Produce 3~5 test pieces after die change before mass production.
