HYDRAULIC Heavy Duty Guillotine Shears

General Features

The entire EU streamlined design, heat treatment frame, high rigidity workbench, optional mechanical
compensation device for precise bending.
Hydraulic synchronization control and Estun NC programmable logic controller ensure precise repeatability
and ease of use.
The integrated hydraulic system (Bosch Rexroth, Germany) can quickly and automatically switch to a slow bend.
The X-axis and Y-axis are programmed by the NC E21 system to achieve accurate positioning of the inverter.
Advanced variable frequency hydraulic control technology, with more stable, and more reliable operation.
The optimal parameter ratio and optimal core configuration ensure stable performance and convenient operation.
WC67K series press brake equipped with standard single-axis backgauge system (X-axis) and single-axis bending
angle system (Y-axis), you can choose to add V-axis compensation function, and select the appropriate mold to
easily bend the workpiece with complex shapes.

1. The machine adopts a split installation structure, which has sufficient strength and rigidity. The internal stress is eliminated through high-temperature annealing to ensure the overall accuracy of the machine.
2. Adopt German large floor boring and milling machine, and use one-time processing method for precision processing to ensure processing accuracy.
3. Hydraulic brake structure.
4. The hydraulic system adopts an integral logic circuit, controlled by a sequence valve, with smooth movement, low noise and simple maintenance.
5. Using domestic famous brand hydraulic valve to control the movement of the knife board and down.
6. The pressing device adopts an integrated circuit and independent parallel pressing cylinders, and the pressing device is equipped with rubber pads. When the sheet is not flat, it can be freely stretched and compressed on the sheet, and the pressing force can also be adjusted according to the material of the sheet. And the thickness can be adjusted automatically without damaging the board surface.

MAIN COMPONENTS

Angle station

This station provides large capacity angle cutting at 90° and 45°. Angles between 45° and 90° can be achieved by first cutting at 90° and then flange trimming to the required angle in the shearing station.

Shearing station

The shearing unit is fitted with a simple robust holddown which is adjustable to any thickness of material within the cutting capacity of the machine. The shear feed table with adjustable guides is fitted to allow accurate feeding of materials. The guide can be adjusted to allow miter cutting up to 45° for flat bars or to trim the flanges of angle.

Punching station

The large punch bed area has a removable front block and is designed to give a very wide range of punching applications. A punch table with rules and guides for repetition work are fitted as the standard machine.
