Key Features of High-Quality Solor Strut Roll Forming\u00a0Machines<\/a><\/p>\n

Core advantages of the high-speed photovoltaic mounting frame forming machine<\/a><\/p>\n

 <\/p>\n

Profile Deformation & Dimensional Errors<\/b><\/strong><\/h2>\n

Issue 1: Twisting, Curving & Tracking Deviation<\/b><\/strong><\/h3>\n

Causes<\/b><\/strong><\/h4>\n

Uneven roll gap on left and right sides.<\/p>\n

Misaligned feeding center of the leveling machine.<\/p>\n

Loose anchor bolts causing frame vibration at high speed.<\/p>\n

Improper deformation distribution among forming passes, leading to residual stress.<\/p>\n

Excessive clearance of roller bearings.<\/p>\n

Solutions<\/b><\/strong><\/h4>\n

Adjust roll gaps symmetrically with feeler gauges to ensure equal pressure on both sides.<\/p>\n

Align the whole line to keep steel strip moving straight without lateral shift.<\/p>\n

Level the main frame and fasten all foundation bolts to eliminate vibration.<\/p>\n

Distribute bending deformation into multiple passes to reduce springback.<\/p>\n

Replace worn bearings to stop roller shaking.<\/p>\n

Issue 2: Out-of-tolerance Dimensions (Flange Height, Opening Width, Angle Springback)<\/b><\/strong><\/h3>\n

Causes<\/b><\/strong><\/h4>\n

Worn forming rollers.<\/p>\n

Uneven thickness of incoming galvanized coils.<\/p>\n

Excessive or insufficient roll pressing depth.<\/p>\n

Q355 high-tensile steel has larger springback than ordinary carbon steel.<\/p>\n

Solutions<\/b><\/strong><\/h4>\n

Polish or replace damaged rollers.<\/p>\n

Reject raw materials with big thickness deviation.<\/p>\n

Fine-tune roll pressure step by step with multi-pass forming.<\/p>\n

Reserve extra compensation angle for high-strength steel to counter springback.<\/p>\n

Issue 3: Edge Wave & Wrinkle<\/b><\/strong><\/h3>\n

Cause<\/b><\/strong><\/h4>\n

Over-bending at edge positions and unstable strip tension.\u00a0<\/b><\/strong><\/p>\n

Solution<\/b><\/strong><\/h4>\n

Divide edge bending into more forming stations, keep consistent feeding tension and remove burrs on rollers.<\/p>\n

Issue 4: Surface Scratches on Galvanized Strip<\/b><\/strong><\/h3>\n

Cause<\/b><\/strong><\/h4>\n

Sharp edges on rollers and guide plates.\u00a0<\/b><\/strong><\/p>\n

Solution<\/b><\/strong><\/h4>\n

Polish all contact parts; install nylon anti-scratch guards to avoid hard friction.<\/p>\n

\"Solor<\/a><\/p>\n

Punching System Failures<\/b><\/strong><\/h2>\n

Hole Pitch Deviation & Poor Position Accuracy<\/b><\/strong><\/h3>\n

Causes<\/b><\/strong><\/h4>\n

Servo encoder drift; wrong PLC timing parameters; unstable feeding speed.\u00a0<\/b><\/strong><\/p>\n

Solutions<\/b><\/strong><\/h4>\n

Recalibrate encoder; reset punching program; stabilize line speed; synchronize hydraulic punching action.<\/p>\n

Big Burrs, Cracked Steel & Broken Punches<\/b><\/strong><\/h3>\n

Causes<\/b><\/strong><\/h4>\n

Excessive gap between punch and die; dull cutting edges; over-high hydraulic pressure.\u00a0<\/b><\/strong><\/p>\n

Solutions<\/b><\/strong><\/h4>\n

Control die clearance within 8%~10% of sheet thickness; regrind tool edges; reduce hydraulic pressure properly.<\/p>\n

Missing Punching & Continuous Punching<\/b><\/strong><\/h3>\n

Check photo sensors and proximity switches; remove oil contamination; re-match feeding and punching timing.<\/p>\n

\"Solor<\/a><\/p>\n

Flying Shear & Cutting Troubles<\/b><\/strong><\/h2>\n

Length Inaccuracy<\/b><\/strong><\/h3>\n

Causes<\/b><\/strong><\/h4>\n

Slipping encoder; lost servo parameters; strip slipping during transportation.\u00a0<\/b><\/strong><\/p>\n

Solutions<\/b><\/strong><\/h4>\n

Lock encoder shaft; reset flying shear parameters; tighten feeding pinch rollers to prevent material sliding.<\/p>\n

Uneven Cuts & Distorted End Profiles<\/b><\/strong><\/h3>\n

Replace blunt cutting blades and adjust blade clearance evenly; add material supports under the profile to reduce bending during cutting.<\/p>\n

High Hydraulic Oil Temperature & Jumping Shear<\/b><\/strong><\/h3>\n

Clean water cooling pipeline; replace hydraulic oil regularly; avoid non-stop high-speed operation without heat dissipation.<\/p>\n

\"Solor<\/a><\/p>\n

Feeding & Mechanical Malfunctions<\/b><\/strong><\/h2>\n

Material Jamming<\/b><\/strong><\/h3>\n

Reduce pressure of leveling rollers; install coil straightener to correct strip camber; re-align the whole production line.<\/p>\n

Excessive Vibration & Abnormal Noise<\/b><\/strong><\/h3>\n

Lubricate bearings and gearboxes regularly; tighten chains and transmission parts; replace worn gears.<\/p>\n

Servo Alarm & Automatic Shutdown<\/b><\/strong><\/h3>\n

Stabilize three-phase power supply; check loose wiring; lower instantaneous line speed to cancel overload protection.<\/p>\n

 <\/p>\n

Routine Maintenance Tips<\/b><\/strong><\/h2>\n

Clean rollers and punching dies every shift;<\/p>\n

Refill lubricant for bearings and reducers daily;<\/p>\n

Re-calibrate center line, roll gap and punching timing every two weeks;<\/p>\n

Keep hydraulic water cooling system running continuously during mass production;<\/p>\n

Produce 3~5 test pieces after die change before mass production.<\/p>","protected":false},"excerpt":{"rendered":"
