WYS 30° Bystronic-Type Acute-Angle Gooseneck Punch, H175 R1

The WYS 30° Bystronic-type acute-angle gooseneck punch is designed for precision bending applications that require both a sharp forming angle and additional workpiece clearance. The tool has an overall height of 175 mm, a width of 22 mm, an R1 punch-tip radius and a maximum rated load of 80 ton/m.

Unlike a conventional straight punch, its relieved gooseneck profile creates space behind the working tip. This clearance helps prevent interference when bending return flanges, U-shaped parts, channels and components that already contain one or more formed edges.

The 30° working angle allows the material to be formed below 90° when paired with a suitable lower die. It can therefore be used for acute-angle bending, controlled overbending to compensate for springback and pre-bending before a separate flattening or hemming operation.

The small R1 tip supports relatively tight bend radii where permitted by the material and forming conditions. The final inside radius, however, also depends on sheet thickness, material properties, lower-die opening and the selected bending method.

Precision-machined mounting and working surfaces help maintain accurate tool alignment and repeatable bending results. Different heights, widths, working angles, tip radii, mounting profiles and sectional lengths can be manufactured according to the customer’s press brake and finished-part drawings.

Technical Specifications

The stated 80 ton/m is the maximum punch load. The actual permissible working force must not exceed the rated capacity of any component in the complete setup, including the punch, lower die, holder, clamping system and press brake.

Typical Applications

• Acute-angle sheet-metal bending
• Overbending for springback compensation
• Pre-bending before flattening or hemming
• Bending return flanges without tool interference
• Forming U-shaped profiles and channels
• Producing boxes, cabinets and enclosure components
• Bending workpieces with existing adjacent flanges
• Forming brackets and complex sheet-metal parts
• Precision bending of mild steel, stainless steel and aluminum
• Use on compatible Bystronic-type CNC, hydraulic and servo-electric press brakes

Product Details / Manufacturing Quality

The principal advantage of this punch is the combination of a 30° working tip and a relieved gooseneck body. The pointed profile enables acute-angle forming, while the recessed section provides clearance for previously bent flanges that could interfere with a straight punch.

With an overall height of 175 mm, the tool also provides extended reach for deeper or more complex parts. Press-brake daylight, stroke, shut height and lower-tool height must be checked before use to ensure that the complete tooling setup is compatible with the machine.

The R1 tip can produce a tight bend line, but tooling selection should not be based on tip radius alone. Material grade, thickness, grain direction, minimum permissible bend radius, V-opening and required tonnage must be evaluated to reduce the risk of cracking, marking or overloading.

For segmented tooling sets, WYS can supply standard or customer-specified section arrangements to simplify loading and support box-bending operations. Tool dimensions and profiles can also be adapted to existing clamping systems or special workpiece geometries.

Standard & Custom Press Brake Tooling

WYS manufactures Bystronic-type straight punches, gooseneck punches, acute-angle punches, radius punches, single-V dies, hemming tools, die holders and special forming tools.

This model can be customized in overall height, body width, working angle, punch-tip radius, relief geometry, mounting profile and tooling length. Continuous lengths, standard segmented sets and special section arrangements are available according to production requirements.

Customers can send WYS their finished-part drawings, material grade, sheet thickness, bending length and press brake specifications. Our engineering team can evaluate flange clearance, minimum bend radius, V-opening, required forming force and bending sequence before recommending or designing a suitable tooling solution.

This product is manufactured by WYS for use with compatible Bystronic-type tooling and clamping systems. WYS is an independent press brake tooling manufacturer, and no official affiliation with the referenced machine brand is implied.
