Custom pipe‑processing equipment includes punching,shrinking,expanding,flaring,crimping,cutting and integrated tube‑end forming machines.Complete technical parameters help manufacturers give accurate quotation,avoid rework and equipment mismatch.Parameters are divided into workpiece parameters,process requirements,equipment performance,production conditions and special custom requirements.
1.Workpiece basic parameters(most critical information)
1.Pipe profile:round tube,square tube,rectangular tube,oval tube or special‑shaped profile.Provide long‑axis/short‑axis dimension for oval tubes.
2.Pipe size range:minimum and maximum outer diameter/side width;maximum raw pipe length that can be loaded.
3.Wall‑thickness range:minimum and maximum wall thickness;clarify main frequently‑processed wall‑thickness.
4.Material:carbon steel,galvanized pipe,201/304 stainless steel,aluminum tube,alloy pipe.Galvanized and stainless‑steel require enhanced die material.
5.Product drawing or sample photo:Attach finished‑art drawing with target dimension after forming(shrunk OD,expanded OD,hole size,hole‑pitch,horn‑mouth angle).
2.Processing&forming technical requirements
For tube‑end forming(shrinking/expanding/flaring/crimping)
-Forming type:shrinking only,expanding only,flaring,crimping,closing,multi‑function composite.
-Cold forming or hot forming.
-Single‑pass deformation amount/expansion ratio;whether multi‑stage progressive forming is needed.
-Dimensional tolerance,roundness requirement,allowable wall‑thickness thinning rate.
-Whether socket fit clearance is required for assembly joints.
For pipe punching/notching
-Hole shape:round hole,square hole,slotted hole,special‑shape notch.
-Hole diameter/hole size,hole‑pitch range,edge distance,unequal‑punching requirement.
-Allowable burr height after punching.
General process requirements
-Maximum effective processing stroke;whether multiple stations are needed.
-Requirement for automatic feeding or manual loading.
-Production efficiency:pieces per minute/per hour,expected daily output.
3.Equipment performance configuration parameters
1.Drive mode:hydraulic,CNC‑hydraulic composite,full‑electric servo.
2.Rated tonnage:maximum forming force or punching force,reserve safety margin for thick‑wall pipes.
3.Control system:ordinary relay,PLC,CNC servo;whether to store multiple programs;mm/inch unit switching.
4.Clamping fixture:special fixture for square/oval tube;adjustable clamping range;anti‑crush function for thin‑wall tubes.
5.Safety requirements:emergency stop,overload protection,safety protection cover.
6.Standard delivery scope:host only,or include standard dies,fixture sets,spare wearing parts.
4.On‑site factory installation conditions
1.Power supply:voltage,frequency(different for different export countries).
2.Approximate available workshop space:length×width,height limit.
3.Cooling condition for hydraulic station;whether oil‑free environment is required.
4.Operation habit:semi‑automatic manual operation preference or fully‑automatic production line.
5.Special customized&commercial requirements
1.Special mechanical modification:enlarged clamping range,reinforced frame for heavy‑load,special mandrel/die cavity shape.
2.Language requirement for HMI display:English or other language interface.
3.After‑sales requirement:on‑site commissioning,remote debugging,spare‑parts supply cycle.
4.Delivery time,warranty terms.
Practical tips for custom order
1.Prioritize provide real‑product drawings or physical sample photos,not only text description.
2.Distinguish“maximum limit parameter”and“daily common‑use parameter”.Machine design should base on frequently‑processed specifications,not only extreme maximum size.
3.Clarify whether dies are included in quotation.Custom dies take extra production cycle and cost.
4.Confirm acceptance standard:dimensional tolerance,forming appearance,production speed before signing technical specification.
Conclusion
When customizing pipe‑processing equipment,workpiece dimension,material and forming requirements are the core basis.Then confirm drive mode,tonnage,control system,factory power‑supply condition and special modification demands.Complete parameter list can avoid deviation between finished equipment and actual production needs.
