oil-seal and chassis circular-blanking application
This revision uses chassis circular blanking as the primary intent; oil-seal blanks are not assumed to share the same material, die or buyer requirement.
Scope and Evidence Status
This URL is written as a bounded technical decision page for automotive chassis circular blanking with a 2-in-1 line and zigzag feeder. It does not claim a confidential customer result, certified finished product or universal machine capability. Any future case-study statement needs the records listed below.
Application-Specific Process Route
The labeled route below is a conceptual engineering diagramโnot a photograph of a delivered project. It makes the current page intent visible without presenting generic equipment images as application proof.
Inputs to Freeze Before Selection
- Released chassis blank drawing and downstream forming route
- Material grade, strength, thickness, width and coil mass
- 2-in-1 straightening/passline and coil-capacity requirements
- Blank geometry, web, edge margin, coil width and traverse demand
- Press window, die clearance, support and scrap discharge
- Utilization calculation, blank inspection and lot traceability
Context Images and Their Limits
Engineering Decision and Verification Table
| Decision gate | How to verify | Required record |
|---|---|---|
| Primary scope | Confirm chassis blank and remove oil-seal equivalence | Approved process statement |
| Conditioning | Measure strip shape after 2-in-1 path | Setup/flatness record |
| Nesting | Verify layout and extreme traverse positions | Calculation/slow-run proof |
| Blank quality | Measure drawing-defined profile and burr | Inspection report |
Page-Specific Method
Failure Modes, Stop Conditions and Boundaries
- Part-family conflation: Require a separate oil-seal application sheet
- Unsupported saving: Publish only a documented baseline/layout calculation
- Traverse collision: Stop if edge margin, support or tooling clearance is not verified
Acceptance Record for This Page
Freeze the released drawing and material revision, machine configuration, interface list, recipe, sample plan and measuring method. Record exceptions and the safe restart route. A publishable result must identify the tested configuration; otherwise retain this page as an engineering guide.
Source and Verification Boundary
HENLI feederโpress commissioning guide. The guide supports commissioning structure; part-specific forming and safety acceptance remain with the approved process plan.
