J23 Series Model D Adjustable Stroke Press for Automotive Precision

The J23 Series Model D Press with adjustable stroke is engineered for applications where precision metal forming tolerances are critical, such as automotive suspension bracket production. Its mechanical frame is constructed from high-grade cast iron with thermal stress relief, ensuring rigidity under full-load operation. The adjustable stroke mechanism allows operators to fine-tune the ram travel from short high-speed cycles for thin sheet work to extended strokes for deep forming processes, all without compromising alignment accuracy.

The flywheel system operates on a precision-balanced shaft supported by double-row spherical roller bearings, minimizing vibration transmission and prolonging die life. Stroke adjustments are made via a precision worm-and-gear mechanism, allowing incremental changes as fine as 0.1 mm to match tooling requirements. The press delivers repeatability within ±0.02 mm, making it suitable for safety-critical components in the automotive sector.

Its clutch and brake combination employs an advanced dry-type friction system with fast engagement response, enabling higher throughput rates without sacrificing positional accuracy. The slide is guided by six-point gibs with automatic lubrication, reducing wear during prolonged production cycles. For automotive suspension brackets, where consistent hole patterns and bending angles are essential, this level of guidance precision directly translates into higher yield rates.

The bed is machined to accept quick-change die systems, allowing rapid tooling swaps and reducing downtime in multi-part production schedules. Integrated overload protection via a hydraulic release system prevents damage to tooling in the event of misfeeds or excessive load conditions. Noise levels remain under 85 dB(A), compliant with industrial safety standards, making it suitable for large-scale production floors.

Automotive manufacturers using the J23 Series Model D Press benefit from its ability to handle both cold stamping and progressive die operations, producing bracket geometries with tight dimensional tolerances and minimal post-processing. The adjustable stroke design also optimizes energy consumption, as operators can match stroke length to material thickness, reducing unnecessary mechanical travel.

FAQ – People Also Ask

Q1: How does adjustable stroke improve stamping accuracy for automotive parts?
Adjustable stroke allows the press to match ram travel precisely to the depth of the forming or punching operation, reducing deflection and improving dimensional consistency.

Q2: Can the J23 Series Model D handle progressive die operations for suspension components?
Yes, its high rigidity and precise slide guidance system make it suitable for progressive die stamping, enabling multiple forming operations in a single cycle.

Q3: What maintenance advantages does the six-point gib guidance system provide?
It reduces side thrust on the slide, minimizes wear on guide surfaces, and ensures long-term accuracy with less frequent adjustment.

Q4: How does stroke optimization impact energy consumption?
Shorter strokes require less flywheel rotation and lower inertial load, resulting in measurable energy savings over extended production runs.

Q5: What is the typical production speed when stamping automotive suspension brackets?
Depending on material thickness and tooling complexity, speeds can range from 45 to 75 strokes per minute with consistent accuracy.
