The shearing machine anti-twist device system is an auxiliary device specially designed to solve the distortion caused by uneven force on the plate during the shearing process. It is usually integrated into the workbench or tool holder system of the CNC plate shearing machine, and exerts reverse restraint force on the plate through a specific mechanical structure or control method, thereby ensuring the shearing quality and the flatness of the plate.

 

1. What is shearing machine anti-twist device?


SC Shearing Machine Anti-twist Device


A shearing machine anti-twist cutting system is an auxiliary device installed on a plate shearing machine, designed to reduce or eliminate the phenomenon of twisting, warping or deformation of the plate during the shearing process.

 

When the metal shear is working, it applies appropriate constraints or supports to the plate through a specific mechanical structure or auxiliary function, thereby improving the shearing quality and processing accuracy.

 

2. Working principle of the anti-twist device of shearing machines

During the shearing process, the plate is prone to twisting or warping at the shearing edge due to uneven pressure distribution or asymmetric force on the blade. The anti-twist device works in the following ways:

 

1) Support and reaction force compensation

During the shearing process, the anti-torsion device provides support to the non-shearing side of the plate through a mechanical arm, a support rod or an elastic device to prevent the plate from warping.

When the shear force acts on the plate, the anti-torsion device will apply a force opposite to the twisting direction to offset the deformation tendency of the plate.

 

2) Clamping and correction

The clamping mechanism equipped with the anti-torsion device will clamp the plate before shearing, fix its position and limit its freedom.

After the shearing is completed, the clamping mechanism is gradually released to ensure the flatness of the sheared edge.

 

3) Automatic adjustment

Modern anti-torsion devices combine sensors and CNC systems to monitor the status of the plate in real time and automatically adjust the support force and reaction force according to the thickness, length and material of the plate.

3. Main components of the shear plate torsion device


Clamping mechanism:

Clamp the plate firmly before shearing to prevent displacement and warping caused by shear force.


Support device:

Located on the non-working side of the shearing area, it provides support for the plate to prevent sagging.


Anti-torsion bar or anti-torsion arm:

Applies a reverse force to offset the twisting tendency generated during the shearing process.

 

Elastic compensation device:

Use springs or hydraulic mechanisms to absorb excess shear stress and reduce plate deformation.

 

4. Working process of the anti-twist device


Before shearing:

The plate is fed into the shearing machine, the clamping mechanism of the anti-twist device clamps the plate, and the support device is adjusted to the appropriate position.


During shearing:

When the shearing machine blade begins to apply shearing force, the support structure of the anti-twist device and the anti-twist arm work synchronously to apply reverse force to offset the warping of the plate.


After shearing:

The anti-twist device gradually releases the clamping force to ensure that the plate leaves the shearing area smoothly and the shearing edge remains flat.

 

5. The role of the anti-twist device for shearing machine


The shearing machine anti-twist device is a key auxiliary equipment in the hydraulic guillotine sheard. Its main function is to reduce or eliminate the distortion caused by uneven force on the plate during the shearing process. The following are the specific functions of the anti-twist device of the plate shearing:

 

1) Prevent the distortion of the plate

When the shearing machine cuts thin plates or large-format plates, the plate is prone to distortion due to uneven force distribution. The anti-twist device effectively prevents this distortion by applying a reverse constraint force to the plate, ensuring that the plate is flat after shearing.

 

2) Improve the shearing quality

By reducing the deformation of the plate, the anti-twist device can significantly improve the accuracy and quality of shearing, ensure that the shearing edge is neat and smooth, and meet the requirements of subsequent processing.

 

3) Reduce subsequent processing steps

Avoiding the trimming process caused by plate distortion, saving time and cost, and improving production efficiency.

 

4) Protecting the shearing machine and blade

The distortion of the plate may cause additional stress on the blade or mold of the shearing machine. The anti-twist device can reduce these stresses and extend the service life of the equipment and mold.

 

5) Adapt to a variety of materials and thicknesses

The modern shearing machine anti-twist device is flexibly designed and can be adjusted according to different materials and thicknesses to adapt to diverse processing needs.

 

6) Improve safety

The distortion of the plate may cause unexpected bounce or slip, increasing the risk of operation. The anti-twist device can reduce these risks and ensure the safety of operators.

 

In short, the anti-twist device of the shearing machine is an important component to ensure shearing accuracy, improve production efficiency and reduce costs, especially in the scene of processing thin plates or high precision requirements.
