Custom Horizontal Bending Tooling for Closed and Complex Sheet Metal Parts
Custom Horizontal Bending Tooling for Closed and Complex Sheet Metal Parts
Shengpu Tooling manufactures custom side-push bending die solutions for sheet metal parts that cannot be formed by standard vertical press brake tooling.
A side-push bending die converts the vertical movement of the press brake into horizontal forming force through a cam, wedge, or side slider structure. This makes it suitable for negative angles, undercuts, closed box parts, internal flanges, deep cavity forming, and complex sheet metal structures.
Core Product Capabilities
- Cam-action Lateral Bending: Converts vertical force into horizontal force (90°); transforms a standard press brake into a “horizontal bending machine” simply by swapping the tooling—no machine modification required.
- Machine-Specific Customization: Designed based on precise measurements of your equipment’s brand, tonnage, stroke, and mounting interfaces to ensure a perfect match.
- Drawing-Based Customization: Supports custom specifications, including special angles, specific radii, forming dies, and irregular groove profiles.
- Prioritizing Structural Rigidity: High-tonnage, short-stroke applications utilize single-piece, solid steel construction to eliminate cumulative errors associated with modular interfaces.
- Materials and Manufacturing: Crafted from tool steels such as 42CrMo and Cr12MoV; features through-hardening (HRC 47±2) and precision grinding; mating error for interchangeable sets is ≤0.04mm; maximum single-piece length exceeds 6,000mm.
Selection and Usage Guide
- Does the workpiece feature negative angles, undercuts, or enclosed structures? Ask first if “side-pushing” is feasible rather than forcing a vertical press. The boundaries of vertical bending are dictated by the direction of force; changing the direction is more effective than increasing tonnage.
- Calculate working clearance by subtracting the total height of the tooling assembly from the machine’s open height; do not rely on the bare machine’s specifications. Installing tooling and clamping systems significantly reduces available clearance, making the bare machine’s open height a misleading metric.
- For horizontal bending operations, estimate tonnage by multiplying the vertical requirement by 1.2 to 1.3. The C-frame of horizontal tooling “breathes” (flexes) and absorbs energy; upgrade machine capacity before addressing precision requirements.
- Tool selection: Prioritize straight blades for horizontal work; minimize clearance gaps, and avoid using deep gooseneck blades on thick plates. Deep-clearance gooseneck blades have a limit of approximately 25 tons/foot, whereas straight blades can withstand 100 tons/foot.
- After a batch of horizontal bending, inspect guide rails for overheating or scoring; stop the machine immediately if an alarm triggers. Excessive lateral off-center loading can permanently damage the machine’s capability for standard bending operations.
- Opt for custom solutions for complex workpieces: Drawings → Proposal → Prototyping → Delivery. Achieve the final shape in a single operation to eliminate errors associated with multiple bending steps and repositioning.
Why Choose Shengpu Tooling
Shengpu Tooling focuses on custom press brake tooling for non-standard sheet metal forming. We manufacture side-push bending dies, side-action bending dies, horizontal bending tooling, upper punches, lower dies, hemming dies, radius dies, offset dies, bridge dies, louver dies, hinge dies, and other special press brake tooling.
Our team can review your drawing and help determine whether a side-push solution is needed, or whether the part can be solved by adjusting the bending sequence or using standard tooling.
