NC Press Brake

Ordinary torsion axis synchronous press brake machine is a kind of common bending equipment, which uses the twisted shaft synchronous mechanism to realize the bending of a metal sheet.

Using the relative movement of the upper and lower die and the support of the workpiece on both sides, the bending of the metal sheet is realized by using the torsion axis synchronous mechanism.

The torsion shaft synchronous mechanism can ensure that the bending Angle of both sides is consistent in the bending process and improve the machining accuracy. Using mechanical operation, the movement of the upper and lower mold is controlled by the mechanical handle or foot-stepping plate, and the operation is relatively simple. It is suitable for bending all kinds of metal plates, including steel plate, aluminum plate, stainless steel plate, etc.

Compared with advanced equipment such as CNC bending machines, ordinary torsional synchronous bending machines have a lower cost and are suitable for some simple processing needs and limited budget scenarios. It is suitable for some simple bending tasks, such as straight line bending, U-shape bending, etc., and may not be suitable for complex curve bending.

How does the ordinary torsion axis synchronous press brake machine accurately maintain the angular consistency of the entire length of the workpiece during the bending process?

The ordinary torsion axis synchronous press brake machine maintains angular consistency across the entire length of the workpiece through its torsion shaft synchronization mechanism. Here’s a breakdown of how this system works to achieve consistent bending angles:

Torsion Shaft Synchronization Mechanism
The torsion shaft is a rigid mechanical link that connects both ends of the press brake machine, synchronizing the movement of the upper beam (ram) during the bending process.
This shaft acts like a rotational spring, ensuring that when one side of the machine moves, the other side moves precisely in sync. This linkage prevents any side-to-side tilt or misalignment, which is crucial for maintaining uniform pressure along the entire length of the workpiece.

Distribution of Force
The torsion shaft evenly distributes the force exerted by the ram across both sides of the machine. This uniform force application means that the bending angle remains consistent from one end of the sheet to the other.
As the upper die presses down on the sheet, the shaft counteracts any potential discrepancies caused by the mechanical tolerances, ensuring that the bending pressure is the same on both sides.

Mechanism Design and Rigidity
The rigid design of the torsion axis prevents any deflection or twisting during the bending operation, which is a common issue with non-synchronized machines. This rigidity is crucial to maintaining the angular precision of the bend.
Any slight movement or flex in one side of the machine is immediately compensated by the torsion shaft, which maintains the parallelism of the upper and lower dies throughout the bending process.

Mechanical Balancing System
The torsion axis synchronous press brake machines often have a mechanical balancing system to correct any small imbalances that could lead to variations in angle. This system ensures that even if there are minor differences in the material properties or thickness along the length of the sheet, the angular consistency is not compromised.
The balancing mechanism works together with the torsion shaft to ensure that the upper beam descends uniformly, maintaining the desired bending angle along the full length of the workpiece.

Manual Adjustments and Calibration
These machines usually allow for manual adjustments to fine-tune the bending parameters. Operators can make slight modifications to the position of the dies or the pressure settings to account for variations in the material or machine wear over time.
Regular calibration of the machine and the torsion shaft is also a standard practice to ensure that the system maintains its precision capabilities over extended periods of operation.

Consistent Tooling and Die Alignment
Proper alignment of the upper and lower dies is crucial for maintaining angular consistency. The design of the ordinary torsion axis synchronous press brake machine ensures that the dies are perfectly aligned, reducing the chance of angular variation.
Using high-quality, consistent tooling that fits precisely with the die setup also contributes to uniform bending angles throughout the entire workpiece.

Key Advantage: Simplicity and Reliability
One of the key benefits of using a torsion axis synchronous system is its mechanical simplicity. Unlike complex CNC or hydraulic systems that rely on sensors and automated controls, the torsion shaft provides a reliable and straightforward solution for maintaining consistent bending angles, making it easy to operate and maintain.

Limitations:
Despite its advantages, this system has its limitations when compared to CNC-controlled machines. It is less capable of handling highly complex bends or compensating for variances in material properties in real-time.

The manual adjustments and dependence on mechanical linkages mean that while it is effective for simpler tasks, achieving ultra-high precision might be challenging without operator intervention.

The ordinary torsion axis synchronous press brake machine uses the torsion shaft to synchronize the movement of both ends of the ram, ensuring even force distribution and mechanical stability. This results in consistent angular bending across the entire length of the workpiece, making it suitable for straightforward bending operations where precise synchronization is required.
