Elevating Deep Drawing with Mechanical Cam Shaft Press and Transfer Press Integration
At H&T ProduktionsTechnologie (HTPT), we engineer production solutions that push the limits of deep drawing for high-precision metallic components. By combining state-of-the-art tooling with the precise kinematics of a mechanical cam shaft press and the flexibility of a transfer press line, we deliver stable processes, tighter tolerances, and higher overall equipment effectiveness.
Why a mechanical cam shaft press for deep drawing?
A mechanical cam shaft press provides hard-timed, repeatable motion that is ideal for deep drawing. Cam-driven auxiliary motions—such as in-die redraw, restrike, flanging, or trimming—can be sequenced with micro-accurate timing relative to the main slide. This deterministic kinematic chain reduces variation at bottom-dead-center, which is critical for ironing zones, wall-thickness control, and surface finish. Tuned cam profiles enable dwell where material needs to settle and sharper acceleration where rapid disengagement prevents galling. The result: predictable forming loads, reduced springback scatter, and longer tool life.
Leveraging the transfer press to de-risk complex geometries
A transfer press allows multi-stage forming with gentle part handling between stations. By distributing draw reduction over sequential dies, we control strain paths and minimize thinning, wrinkling, and earing. Servo-driven transfer rails and press-to-transfer synchronization protect delicate features and coatings. For high-depth ratios or asymmetric cups, station-by-station optimization—blank shape tailoring, progressive draw-bead geometry, and localized blankholder zoning—keeps the part on the safe side of the forming limit curve.
Process engineering that makes the difference
- Material behavior: We design around anisotropy (r-values) and plan earing mitigation through blank contouring and draw-bead placement. Aluminum (5xxx/3xxx), stainless, and low-carbon steels each receive a tribology strategy that matches their adhesion and work-hardening characteristics.
- Cushion and blankholder control: Multi-zone hydraulic or nitrogen cushions provide spatially varying blankholder forces to manage material flow. In redraw stages, precise BDC dwell from the mechanical cam shaft press stabilizes ring compression and limits wrinkle initiation.
- Tribology and tooling: DLC, CrN/TiCN coatings and micro-textured surfaces prevent pickup and scoring, extending intervals between maintenance. Optimized radii, entry angles, and ironing percentages minimize friction and temperature spikes.
- Metrology and sensing: In-die force and displacement signatures, acoustic/vibration monitoring, and die-protection sensors enable closed-loop adjustments. We correlate tryout data with FEM to converge faster from simulation to serial production.
Digital reliability and uptime
Condition monitoring of bearings, cams, and transfer axes supports predictive maintenance. Quick-die-change concepts, standardized interfaces, and modular auxiliary cams shorten changeovers and sustain OEE in high-mix environments.
Proven outcomes
When deep drawing is orchestrated across a mechanical cam shaft press and a transfer press, manufacturers gain consistent wall thickness, improved roundness/flatness, and lower scrap—particularly on tight-tolerance parts with challenging aspect ratios. HTPT’s integrated approach—simulation-led design, precision tooling, robust kinematics, and data-driven control—turns difficult geometries into stable, scalable production.
