The 1400mm Long Panel Bender Counterblade is a precision fixed lower support tool designed for flexible panel benders and automated sheet metal bending centers. Installed beneath the sheet, it works with the upper blankholder to clamp, support and position the material accurately along the programmed bending line.

This counterblade has an overall width of 128 mm, an overall height of 65 mm and a reinforced load-bearing height of 40 mm. Its extended 1400 mm construction provides a longer continuous supporting surface than the previous 1000 mm model, making it suitable for larger panels, long enclosures and extended flange-bending applications.

During the bending cycle, the blankholder clamps the sheet against the counterblade. The counterblade remains the stable lower reference while the upper or lower bending blade follows its CNC-controlled trajectory to form the projecting flange.

The tool is manufactured from 42CrMo alloy steel and receives overall quenching and through-hardening to HRC46–52. For a 1400 mm counterblade, careful control of material preparation, heat treatment, machining and straightness is essential to maintain consistent support across the complete working length.

WYS Machinery can manufacture replacement and customized counterblades according to original tooling drawings, physical samples, machine mounting dimensions and customer workpiece requirements.

Function and Working Principle

The counterblade is the fixed lower component in the panel bender tooling system. It supports the sheet from below and works with the blankholder to define the bending line.

During a typical bending cycle:

The sheet is positioned over the counterblade.
The upper blankholder moves toward the material.
The sheet is clamped between the blankholder and counterblade.
The counterblade provides stable lower support.
The upper or lower bending blade forms the projecting flange.
The blankholder releases the material after the bend.

The counterblade does not perform the main forming movement. Its purpose is to provide stable support, accurate sheet positioning and a consistent lower reference.

Difference from the 1000mm Counterblade

Feature	Previous Model	This Model
Overall Width	128 mm	128 mm
Overall Height	65 mm	65 mm
Load-Bearing Height	40 mm	40 mm
Tool Length	1000 mm	1400 mm
Main Application	Standard-length panels	Longer panels and extended bending lines
Supporting Surface	Standard continuous length	Extended continuous support

The 1400 mm version expands the available clamping and supporting length while retaining the principal profile and working function of the shorter model.

40mm Load-Bearing Section

The 40 mm load-bearing height is the reinforced structural section responsible for receiving and transmitting supporting and blankholding forces during the panel bending cycle.

This section helps provide:

Stable support beneath the sheet
Reliable transfer of blankholding force
Structural rigidity across the working length
Consistent reference height
Resistance to repeated operating loads
Reduced risk of unwanted tool deformation

The required load-bearing dimensions can be customized for different machine structures and operating conditions.

128mm Support Profile

The 128 mm width provides a broad structural profile for reliable support and machine installation. Its tapered upper geometry positions the working area near the bending line, while the stepped lower section provides clearance for mounting and surrounding machine components.

This profile can be customized according to:

Machine installation dimensions
Blankholder geometry
Required bending-line position
Upper and lower blade trajectories
Mounting-hole arrangement
Workpiece and flange geometry

1400mm Continuous Support Length

The extended 1400 mm length is the main characteristic of this model. It provides a continuous lower reference beneath long sheet metal components.

Advantages include:

Longer uninterrupted supporting surface
Suitability for extended bending lines
Reduced need for multiple short sections
Consistent reference geometry across larger panels
Easier alignment for appropriate long-tool installations
Support for long doors, cabinets and enclosure panels

The actual usable bending length depends on the panel bender configuration and tooling installation.

Straightness and Alignment Requirements

Long counterblades require careful dimensional control because variation across the working length can influence sheet contact and clamping consistency.

Important inspection points include:

Straightness across 1400 mm
Parallelism of supporting and mounting surfaces
Consistent working height
Mounting-hole position
Profile uniformity
Heat-treatment deformation
Alignment with the upper blankholder

WYS inspects the critical dimensions according to the confirmed drawing and customer requirements.

42CrMo Material and Heat Treatment

The counterblade is manufactured from 42CrMo alloy steel and undergoes overall quenching and through-hardening to HRC46–52.

This manufacturing standard helps provide:

Reliable mechanical strength
Consistent hardness through the tool body
Resistance to repeated clamping loads
Improved wear resistance
Stable supporting geometry
A suitable combination of toughness and hardness

Heat-treatment control is particularly important for long tools because excessive distortion can affect straightness and alignment.

Role in the Complete Panel Bender Tooling System

Tooling Component	Main Function
Blankholder Tool	Clamps and positions the sheet from above
Counterblade	Provides fixed lower support and bending reference
Upper Bending Blade	Produces controlled downward bending
Lower Bending Blade	Produces controlled upward bending
Special Panel Bender Tools	Support special clearance or forming requirements

Unlike a conventional press brake lower die, this counterblade does not use a V-opening. It supports the sheet while the bending blades move around the clamped bending line.

Typical Applications

This long counterblade can support the production of:

Long electrical cabinet panels
Control enclosures
Switchgear systems
Elevator doors and panels
Metal doors and frames
HVAC and ventilation panels
Server and communication cabinets
Storage cabinets and shelving
Industrial equipment covers
Stainless steel kitchen equipment
Appliance housings
Lighting enclosures
Metal furniture components
Long box-shaped sheet metal parts
Multi-sided enclosures
Customized industrial panels and profiles

Actual suitability depends on the machine model, sheet dimensions, material thickness, tooling arrangement and workpiece geometry.

Frequently Asked Questions

What is a panel bender counterblade?

A counterblade is the fixed lower support tool that works with the upper blankholder to clamp and position the sheet along the bending line.

How does this model differ from the previous counterblade?

The principal confirmed difference is its 1400 mm length. The previous model is 1000 mm long, while this version provides a longer continuous supporting surface.

Is the counterblade the same as a lower bending blade?

No. The counterblade remains fixed and supports the sheet. The lower bending blade moves against the projecting flange to perform an upward bend.

What does the 40 mm load-bearing height mean?

It is the reinforced structural section that receives and transfers supporting and blankholding forces during operation.

What material and hardness are used?

The tool is manufactured from 42CrMo alloy steel, overall quenched and through-hardened to HRC46–52.

Can other lengths be manufactured?

Yes. WYS can manufacture customized continuous lengths, segmented counterblades or matched sections.

Can the mounting-hole pattern be customized?

Yes. The hole quantity, position and installation interface can be produced according to original drawings or samples.
