Torsion Bar NC Press Brake Machines TB 4025

The connection of the hydraulic cylinders of the machine is made using a torsion shaft. The positioning of the hydraulic cylinders is controlled by a synchronization rod. The torsion shaft drives the traverse on both sides. The NC controller coordinates the movement of the rear stops and the operation of the hydraulic cylinders. Machine cylinders and high power main motor ensure reliable operation of the entire hydraulic system.

Precision robotic assembly of the heat-treated one-piece C-frame allows long-term trouble-free operation 24/7. Advantages of the machine design: large space for side installation of the bending tool: Possibility of extracting complex corner parts from the side.

Thanks to the Amada-Promecam type bending tool mounting system and the adjusted coaxiality of the machine, any set of sections can be mounted on Wattsan machines without centering.

Matrices of the Amada-Promecam system have a base of 60 mm and are installed on the machine table through various types of adapters. In this way, 1V, 2V and 4V strand matrices can be fixed.

The four-sided matrix of the machine can be solid or for the entire length of the bend. This expands the range of your possibilities. Thanks to the standard for machine tool builders
and the tool of the Amada-promecam system and the adjusted alignment of the machine (matrix and punch), any set of sections can be installed on the machine without the need their centering, depending on your tasks.

Wattsan bending machines have a universal table with a base of 60 mm (universal size), this is the standard of the Promecam system, which makes it possible, even if the shape of the matrix and the table do not match, to install them into the appropriate holders.

An important feature for achieving a perfect bend is the stability of the backgauge, which allows you to produce a flawless and correct product. The backgauges move along linear guides and are moved by a stepper motor.

The motorized Z-axis movement eliminates manual movement of the backgauges when changing operations, which speeds up the production process and saves operator time.

The machine has front sheet support. Simplifies the supply of material to the bending area. They also ensure the stability of the sheet position at each stage of bending.

The TB series machines are equipped with a reliable ESTUN E21 controller. The numerical controller is the optimal solution for the production of simple and repeatable elements. ESTUN E21 has a program saving function. Very easy to use and has an intuitive menu:
– Saving up to 40 programs with 25 steps each
– 24 buttons for fine tuning
– Manual, automatic single and serial operation modes
– Selectable inch/mm units
– Accuracy of movement along the axes – 0.1 mm
– Error diagnostics

The X-axis is driven by a ball screw, which achieves high precision due to a finer and smoother pitch with minimal friction. The main components of the press brake are manufactured with precision, which ultimately affects the bending accuracy and high quality of the final products. The backgauges move along linear guides and are moved by a stepper motor.
