2.The main structure and performance of the machine tool:
This machine tool is designed and manufactured using the latest
technology, ensuring its strength, rigidity, and safety. Its simple
and elegant appearance and exquisite workmanship demonstrate
meticulous machining and component assembly. The machine utilizes a
single, high-quality welded steel structure, resulting in a thick,
rigid frame. The machine surface is sprayed with imported
rust-resistant primer and topcoat, ensuring it remains as good as new
for a long time. The frame and upper working slide are machined using
imported large-scale CNC floor-type boring and milling machines,
ensuring the required positioning accuracy of all mounting
surfaces.
This machine tool primarily consists of a frame, upper slide,
backgauge system, slide, synchronous control device, mold, hydraulic
system, and control system.
2.1 Frame: This part is a frame-shaped structure, consisting of a
worktable vertical plate, left and right side plates, and connecting
beams. It is welded from steel plates, offering excellent rigidity,
high strength, and excellent resistance to distortion and deformation.
Surface shot peening and other processes eliminate internal stress,
ensuring the long-term stability of the machine's overall accuracy.
During bending, the upper slide and worktable exhibit minimal
deformation, ensuring excellent workpiece straightness and angular
consistency.
2.2 Upper slide part: The left and right cylinders are fastened to the
frame with bolts, and the cylinder piston rod and the slider are
connected with a spherical washer and a screw. This structure can
improve the working condition of the piston rod and the combination
performance of the piston rod and the slider when the slider is
subjected to an offset load; the slider and the frame are connected by
a rectangular guide pair with a self-lubricating function; a grating
ruler with a measuring accuracy of 0.005 mm is installed on the
C-shaped plates on both sides of the frame to detect and feedback the
synchronous movement state of the two cylinders to control the stroke
position of the slider.
2.3 Mold and Clamping Device: The mold consists of an upper mold and a
lower mold, both of which are of high quality and durable. The upper
mold is mounted on a slide and secured by a precision quick clamping
device. The lower mold adopts a double V concentric structure, which
makes mold changes convenient and fast, reduces labor intensity, and
improves production efficiency.
2.4 Front Support: This component is standard and is installed on the
front of the workbench. When in use, the support can be manually moved
to the appropriate position and tightened according to the length of
the workpiece. The support can be adjusted in the horizontal and
vertical directions.
2.5 A unique throat deformation compensation device: A grating scale
is installed on each side of the machine tool to measure and provide
feedback on the precise distance between the slide and the lower
worktable. The scale is connected to the worktable via a C-shaped
bracket, minimizing the impact of frame throat deformation on the
slide position. During operation, the slide's position data is fed
back to the CNC system, which then outputs signals to control the
operation of two sets of hydraulic proportional servo valves,
respectively, ensuring precise synchronization between the two
cylinders.
This structure enhances the machine's ability to resist off-center
loads and effectively prevents non-standard workpieces from colliding
with the scale.
2.6 Back gauge: Adopting the latest Belgian design, the precise and
stable back gauge features a servo motor-driven ball screw, which is
characterized by high speed and high positioning accuracy. The novel
and unique double linear guide structure ensures excellent positioning
accuracy. The multi-stage gear design increases the positioning range
and provides excellent value for money. The modular design allows the
number of control axes to be choiceed from single-axis X to multiple
axes.
2.7 Suspension arm system: The suspension arm system is more
ergonomic, with a reasonable rotation radius, more flexible and easier
to operate.
2.8 Mechanical compensation: Use integral mechanical compensation
wedges, driven by motor, to adjust the accuracy of the workbench;
3. Hydraulic System:
3.1 Utilizes the German-made Bosch Rexroth/PHUCHIN hydraulic system
assembly, featuring an integrated design, compact structure, and
strong sealing performance.
3.2 The main oil cylinder seal ring adopts German SKF/American PARKER
original seal ring, which has excellent sealing performance, reliable
operation and long service life.
3.3 The oil pump adopts Hydeke high-performance internal gear pump,
which has high volumetric efficiency, small flow and pressure
fluctuations, low noise, light weight, wide viscosity range and good
oil absorption characteristics.
3.4 Use high-quality pipe joints to ensure that the hydraulic pipeline
is leak-free.
3.5 The hydraulic oil tank, made of special oil-resistant material,
easily achieves extremely high cleanliness, ensuring stable operation
of the hydraulic system.
3.6 A clear and intuitive oil level and temperature display is
provided.
4. Electrical Control System:
4.1 Electrical components primarily utilize French J51264504
SCHNEIDER brand components, meeting international standards and
ensuring safety, reliability, and strong anti-interference
capabilities.
4.2 A removable footswitch control station provides power on, power
off, and emergency stop functions for easy operation.
