Hollow Articles TRIZ Cases
- Spacer Member Controls Panel Punch for Shell Depth
A spacer member constrains panel punch movement to maintain consistent shell unit depth despite thermal expansion of the die core ring.
- Slide Assembly for Forming Turret Ram
Rolling elements in the slide assembly reduce side loads and prevent misalignment during extended strokes.
- SMC Hollow Components Using Leachable Salt Cores
Salt-based disposable cores eliminate heavy permanent structures, reducing component weight and manufacturing costs for lightweight automotive parts.
- Metal Closure Forming via Alternating Expansion and Reduction
Alternating expansion and reduction steps distribute deformation stress, enabling complex metal closure shapes without splitting.
- Bottom Mould Elevating and Unilateral Clamping Linkage
A single rotation shaft drives a cam and swing member to elevate and lock the bottom mould.
- Triple Turret Can Infeed Transfer Mechanism
A transfer turret with matched pocket counts aligns can bodies between infeed and waxing stations, preventing crushing during die necking.
- Stepped Taper Formation on Tubular Workpieces
Hot forming at 700-1450°C produces steep shoulders on tubular workpieces without wall thickness reduction, maintaining mechanical stability.
