The special hydraulic press for head stretching mainly uses 45
steel plate welded parts, which have undergone tempering vibration
aging treatment. The frame design has been analyzed by finite
element analysis, and has high rigidity and precision. It ensures
the small deformation of the machine and is more convenient to use.
Customized workbenches with front and rear movement are also
available. Its performance characteristics:
1. The head is directly stretched and formed by a mold, which is
currently a relatively advanced process;
2. Smooth pressing, uniform thickness, and standard geometric
dimensions, with a roundness error of ± 1.0mm. After stretching and
forming, the surface is very smooth and the strength increases,
which belongs to cold processing;
3. Easy to operate, high degree of automation, high production
efficiency, no burrs after forming, consistent size, and good
welding process;
4. Complete machine equipment, hydraulic energy conversion, no
noise, continuously variable speed, durable equipment, and long
service life;
3000 ton head stretching hydraulic press 3000 ton head four column
hydraulic press is a customized head stretching hydraulic press by
the customer. The equipment has a generous and beautiful design,
compact structure, simple and reliable operation, and convenient
maintenance. The 3000 ton stretching hydraulic press equipment is
suitable for cold pressing bending, stretching forming and other
processes of metal sheets. It is a specialized equipment for
producing large heads, stretching cylinders, and large metal
containers. The structure of the head hydraulic stretching machine
designed and produced by our company effectively improves the
efficiency and quality of head processing, and reduces the labor
intensity of workers.
The large stainless steel head stretching and forming four column
hydraulic press belongs to the cold pressing and stretching
machine, and its characteristics are:
1. Can achieve the requirement of a pressure edge force and a
tensile force of 1:1. Expand the scope of machine use. Equipped
with edge pressing beams and stretching beams, the flexible control
of the floating tension force with the edge pressing force is
utilized to achieve the control of the cold stretching extension
curve of thick plates;
2. Quick mold changing device and edge pressing mold locking device
can improve mold changing efficiency, reduce mold cost, and
simplify edge pressing mold process;
3. Automatic feeding device can improve the production efficiency
of the head;
4. Equipped with the function of rotating the inner top cylinder
after being pushed out, it can meet the oil coating process of the
head during processing, and the outer top cylinder is equipped to
expand the demolding function of the press
1, Host body
The body of the head stretching forming hydraulic press adopts a
three beam and four column hydraulic press structure, designed
using 3D modeling and computer finite element analysis technology.
The main oil cylinder and four (or six. eight) edge pressing
cylinders are all installed on the upper crossbeam. The main oil
cylinder is a stretching cylinder, which is connected to the piston
head through the reserved through-hole on the sliding beam; The
edge pressing cylinder is connected to the sliding beam, which
drives the annular edge pressing mold to generate edge pressing
force. Therefore, it is also known as a non offset head stretching
machine in the industry.
The hydraulic press for head stretching and forming can adjust the
stretching force and edge pressing force within the range of
0-25MPa according to process requirements. The stretching force can
flexibly fluctuate with the edge pressing force, making the head
forming effect more in line with production requirements: uniform
thickness, standard geometric dimensions, roundness error within ±
0.1mm, smooth surface, and no wrinkles
2, Hydraulic system
The hydraulic system of the head stretching forming hydraulic press
adopts integrated control of two-way plug-in valves, with a compact
structure, convenient installation and maintenance, and dynamic
sensitivity and reliability, high transmission rate, and good
sealing performance; Hydraulic control adopts proportional control,
with high pressure output accuracy, stable stretching process, and
low noise.
3, Online consultation of electronic control system
The electrical control system of the head stretching forming
hydraulic press adopts servo+PLC control, equipped with a Japanese
Omron industrial touch screen display, which can read and set
various parameters on the touch screen, and is connected with
high-precision pressure sensors and displacement sensors. It can
achieve manual and semi-automatic operation modes, comprehensively
considering various production process elements, and achieving a
win-win situation of production efficiency and humanization.
The head stretching forming hydraulic press is also equipped with
an oil temperature detection device, a forced circulation cooling
system (which can ensure that the press is under oil temperature
control of 55 ℃), an automatic oil level detection device, a safety
emergency stop device, and an anti misoperation stop system. It can
also be equipped with a fast automatic feeding device, mold
changing device, edge pressing mold locking device, and a movable
workbench as needed, thereby improving the mold changing time and
efficiency of workers during the mold changing operation, Reduced
the cost of molds and the labor intensity of workers, simplifying
the process of edge pressing molds. It is also possible to
configure the rotation function after the top cylinder is pushed
out, which meets the oil coating process of the head during
processing.
WUXI JINQIU MACHINERY CO.,LTD.
WxiJiniu Machinery Co.,ltd. formerly known as Wuxi Metallurgical Machinery Factory, registered trademark for "Jinqiu" brand, was founded in June 1969. It is in Wuxi city, 150 kilometers far from Shanghai city. We have been to stated enterprise, since 2002, we recombined to private company, and got fast development, we are one big group now, our group mainly produces hydraulic press brake, hydraulic shears, coiling feeding line--especially for aluimnum cap making, slitting line, cut to length, transformer machines....and other series product. It is one of the earliest factory in China to make these metal sheet machines.
