4 Column Cutting Machine Base Q&A<\/span><\/p><\/h1><\/div>

I. Informazioni di base sul prodotto<\/strong><\/span><\/p>\n<\/div>

Q1: What is AFC\u2011780 Four\u2011Column Hydraulic Cutting Machine?<\/span><\/span><\/strong><\/p>\n

A1: AFC\u2011780 Four\u2011Column Hydraulic Cutting Machine is 80\u2011ton heavy\u2011duty hydraulic die\u2011cutting machine. It adopts double\u2011cylinder & double\u2011crank\u2011connecting\u2011rod automatic balance mechanism and four\u2011column rigid guide frame. The upper platen switches to slow\u2011cut automatically when touching die\u2011cutter. Equipped with central automatic lubrication system, optional PLC micro\u2011computer control. It performs multi\u2011layer punching for various flexible materials with die\u2011cutting tools, widely used in shoe\u2011material, luggage and handbag industries as downstream cutting process after laminating, fabric\u2011inspection and rewinding.
\nExtension: Compared with ordinary gantry cutting machine, this four\u2011column model has higher rigidity and 80\u2011ton large pressure, better for thick\u2011material and multi\u2011layer stack cutting. Heavy machine weight requires load\u2011bearing floor.<\/p>\n<\/div>

Q3:What are the main features of AFC\u2011780 Four\u2011Column Hydraulic Cutting Machine?<\/span><\/strong><\/p>\n

A3:<\/p>\n

1.Double\u2011cylinder plus precise double\u2011crank\u2011connecting\u2011rod automatic balance mechanism ensures even force distribution, stable powerful cutting force, reduces shaking & deformation and improves finished\u2011product yield.
\n2.Four\u2011column rigid frame sustains long\u2011time heavy\u2011duty production, minimizes cutting offset error and extends service life.
\n3.Auto slow\u2011cut when platen touches die\u2011cutter. Consistent dimension between top\u2011layer and bottom\u2011layer workpieces during multi\u2011layer stacking cutting, reduce dimension\u2011offset defects.
\n4.Max 80\u2011ton hydraulic output, suitable for multi\u2011layer punching of flexible materials with various thickness and hardness.
\n5.Central automatic lubrication system maintains moving pairs, preserves machine precision and reduces component wear.
\n6.Optional PLC integrated control; parameters such as cutting pressure and stroke can be adjusted according to process.
\n7.Safety operation logic: cutting action triggered only by pressing two\u2011hand buttons simultaneously; equipped with counter, cutting\u2011depth controller, lifting\u2011height controller; dual\u2011protection of brake die\u2011lifting and emergency stop.
\nExtension: Die\u2011cutter sharpness directly affects cutting quality and machine load. Blunt die causes insufficient pressure and abnormal noise. For heavy\u2011duty hydraulic machine, wait for full hydraulic\u2011system cooling before maintenance.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

A7:Place machine on flat hard load\u2011bearing floor and level whole unit. Reserve surrounding clearance for die\u2011cutter lifting\u2011handling and maintenance. Keep away from high\u2011temperature & open\u2011fire; no obstacles above worktable.
\nExtension: Do not place tight against wall for maintenance access. Reserve space for heavy die\u2011cutter handling.<\/p>\n<\/div>

Q8:What is complete test\u2011running operating procedure for AFC\u2011780 Four\u2011Column Hydraulic Cutting Machine?<\/span><\/strong><\/p>\n

A8:<\/p>\n

1.Confirm reliable power earthing; clean impurities inside oil tank, fill hydraulic oil up to about 80% tank volume. Make motor rotation direction consistent with arrow mark on oil\u2011pump housing; level whole machine.
\n2.Clean worktable surface, place die\u2011cutter at center position of worktable.
\n3.Enter setting mode, platen moves slowly down close to die\u2011cutter; operate stroke\u2011setting handle for 2 reciprocating cycles, lock handle and exit setting mode.
\nExtension: Do NOT place hands between platen and die\u2011cutter during die\u2011setting.
\n4.Adjust cutting\u2011depth controller and lifting\u2011height controller. Platen lifting height shall be slightly larger than total thickness of die\u2011cutter plus stacked material.
\n5.Load stacked test material, press two\u2011hand operation buttons simultaneously for trial cutting. Check whether parts are fully cut\u2011through; fine\u2011tune cutting depth. Start mass\u2011production only after sample acceptance.
\n6.Counter counts automatically during mass\u2011production. Press brake button for instant platen lifting when material is jammed; press main emergency\u2011stop for severe abnormality.
\n7.Shutdown for maintenance: cut off main power; wait until hydraulic cylinder system fully cools down; place support block between platen and worktable before repairing.<\/p>\n<\/div>

Q9: What precautions for stroke and cutting\u2011depth adjustment?<\/span><\/strong><\/p>\n

A9:Lifting height only needs to be slightly higher than total thickness of die\u2011cutter plus material. Excessive stroke shall be avoided to reduce idle\u2011run loss. Set cutting\u2011depth just for full material penetration; do not over\u2011press to prevent over\u2011impact on die\u2011cutter and machine. Re\u2011perform die\u2011setting procedure after die\u2011cutter replacement.
\nExtension: Re\u2011check depth and stroke parameters when stacked\u2011material thickness changes; do not reuse old parameters directly.<\/p>\n<\/div>

Evaluate wear of oil cylinder, oil pump and sealing parts; replace aged & worn spare\u2011parts.<\/strong> Extension: For long\u2011term shutdown, lower platen to low position and apply dust\u2011proof protection.<\/p>\n<\/div>

Q15: : Common faults and troubleshooting guidelines?<\/span><\/strong><\/p>\n

A15:<\/p>\n

    \n
  1. No power & indicator lamp off: burnt transformer fuse; emergency\u2011stop locked. Replace fuse and reset emergency\u2011stop.<\/li>\n
  2. Indicator lamp on but motor fails to start: tripped protection switch; burnt main\u2011control contactor contacts; damaged motor. Troubleshoot item\u2011by\u2011item.<\/li>\n
  3. Motor runs but no cutting action: wrong die\u2011setting\u2011switch position; reversed oil\u2011pump rotation; loose wire terminals; burnt solenoid\u2011valve coil or stuck valve\u2011core; loose stroke handle. Reset and check each item.<\/li>\n
  4. Insufficient cutting pressure, incomplete penetration: excessive stacked layers; insufficient cutting\u2011depth setting; clogged oil filter; worn oil pump. Reduce stacking layers, adjust parameters, clean or replace spare\u2011parts.<\/li>\n
  5. Oil leakage: aged cylinder oil\u2011seal; loose high\u2011pressure pipe joints. Replace oil\u2011seal and tighten joints.<\/li>\n
  6. Abnormal loud oil\u2011pump noise: worn internal pump parts; clogged filter leading to insufficient oil suction; damaged bearing or oil\u2011seal. Replace worn components.<\/li>\n
  7. Slow cutting speed & continuous pressure drop: defective solenoid valve; burnt\u2011out relay; aged cylinder seals; deteriorated hydraulic\u2011oil viscosity. Repair electric parts or replace hydraulic oil & seals. Extension\u2011added frequent site faults:<\/li>\n
  8. Big dimension deviation between top\u2011bottom layers in multi\u2011layer cutting: inspect double\u2011crank\u2011connecting\u2011rod balance mechanism; check four\u2011column guide clearance; verify auto slow\u2011cut function is active.<\/li>\n
  9. Counter does not count: Inspect counter\u2011sensor wiring; clean oil stain on sensor surface.<\/li>\n<\/ol>\n<\/div><\/div><\/div><\/div><\/div>

    \u516d.Model Selection<\/strong><\/span><\/p>\n<\/div>

    Q16:Which customers are suitable for AFC\u2011780 Four\u2011Column Hydraulic Cutting Machine?\u00a0<\/span><\/strong><\/p>\n

    A16:Recommended for shoe\u2011making factories, handbag\u2011luggage factories and sports\u2011goods processors. Require 80\u2011ton large pressure for multi\u2011layer die\u2011cutting of leather, shoe\u2011material and luggage flexible materials. Can be matched upstream with laminator, fabric\u2011inspection rewinder and rewinding machine.
    \nExtension:
    \n\u2705 Suitable scenarios: die\u2011cutting for thick\u2011material & multi\u2011layer stacking; require high machine rigidity to reduce cutting deviation; medium\u2011large\u2011batch die\u2011cutting production.
    \n\u274c Unsuitable scenarios: processing metal or rigid hard plastic; only low\u2011pressure single thin\u2011sheet cutting; workshop floor cannot bear 3.4\u2011ton load.
    \nAlternative suggestion: Choose ordinary gantry\u2011type cutting\u2011machine for small thin\u2011part processing to reduce investment.<\/p>\n<\/div><\/div><\/div><\/div><\/div>
