Press Machine Process of Stainless Steel Composite Bottom Pan
Item No. - CKL 019
Press Machine can used for pressure welding process of stainless steel composite bottom pan. It belongs to a traditional structural form of the screw press, and its main feature is that the flywheel is driven by a friction mechanism.
Specifications
Advantage
- Frame: The frame of the J54-4000 40000KN double disc friction press
requires sufficient strength and rigidity. A combined prestressed frame
structure is adopted. There are positioning rings between the base, left
and right columns, and beams for positioning, and four pull rods are
electrically heated and pre-tightened to form a closed frame. Left and
right support arms are installed at both ends of the upper part, which
is convenient for installing the transmission device.
- Transmission control system: The transmission is driven by double
motors. There are two control cylinders installed at both ends of the
transmission shaft, through which the air is fed into the cylinders to
push the piston to move left and right, so that the left and right
friction discs are alternately pressed against the flywheel, so that the
flywheel drives the slider to move up and down, and the forging is
completed, blow.
- Flywheel: The press adopts an overloaded slipping flywheel. When
overloaded, there will be relative sliding between the wheel body and
the wheel rim to play a role of safety insurance.
- The body of the slider is made of high-quality cast steel. The lower
end of the screw in the slider is equipped with a nut. After the nut is
tightened, a round pin is driven in to prevent loosening and falling
out. The slider guide adopts a long X-shaped guide rail, which improves
the guiding accuracy and enhances the anti eccentric load capacity of
the product. The gap between the slider and the rack guide rail can be
adjusted by means of adjusting the inclined iron.
- Protection platform: This machine is equipped with a safety
protection platform, which is the installation basis of the braking
device. It is welded by channel steel and angle steel. There is also a
rat cage ladder for the upper and lower platforms. It is convenient for
the installation and maintenance of transmission control.
- Braking system: The braking consists of two identical sets of braking
devices, which is symmetrically installed on the platform. The upper
part is tensioned by a tie rod, and the lower part is fixed on the
platform by screws.
- There are set screws on the platform to prevent the base from moving.
When braking, the piston rod chamber of the cylinder is exhausted. When
the rodless chamber is inhaled, under the joint action of spring force
and compressed air, the piston rod pushes the brake plate through the
shaft to press the outer edge of the flywheel, so as to achieve the
purpose of braking.
- Balance cylinder: The slider balance device is composed of two
balance cylinders, which is symmetrically distributed on the front and
back of the machine beam, and are used to balance part of the weight of
the motion system, avoiding the sudden drop of the slider, making the
slider move smoothly when it goes down, and is conducive to Slider
return.
- Ejection: Pneumatic double ejector rod structure is adopted, the
ejection force is 20kN, and the ejection stroke is 200mm.
- Air pipeline system: The air pipeline system is compressed air, which
is used to provide power to the transmission control, brake opening and
slider balance device. The pneumatic system is composed of an air
storage tank, a reversing valve, a pressure reducing valve, a
lubricator, safety valve etc.
- Lubrication: The equipment adopts centralized automatic lubrication
and decentralized manual lubrication. The four guide rails and the screw
pairs of the main lubrication points use an electric pump and an
automatic oil separator to automatically inject lubricating oil for
lubrication. The cylinder is lubricated by automatic oil spraying with a
lubricator installed in the air pipeline, and all other places that need
to be lubricated are lubricated with oil guns or grease cups.
- Foundation: The buyer invites a qualified civil engineering design
institute according to the installation foundation drawing provided by
the seller, and organizes the civil engineering construction after
converting the design into construction drawings according to the local
soil conditions. The thickness of the foundation cement pouring layer
should be determined by the user after exploration according to the soil
quality of the workshop. The foundation should have a waterproof layer
to prevent groundwater from seeping into the pit.
- Electric control system: It consists of a strong electric drive part
and a PLC (OMRON) control part. The control circuit is reasonable, the
movement is reliable, and it is easy to use. The main motor adopts
star-delta starting mode, which reduces the impact of starting current.
