Shutter Door Roll Forming  Machine

    The roll forming machine consists of 3-ton manual uncoiler, infeed guide, fixed position driven forming stations, rectifying device, cutting equipment, hydraulic station, PLC control console, and manual unload product run out table. 

   Material of Main Equipment

Roller Material	High grade S45C forged steel, coated with hard chrome.
Active Shaft Material	High grade S45C carbon wrought steel, diameter 76mm.
Electric Elements	PLC control console, touch screen and transducer, from Siemens, Germany. Other elements, from Schneider Electric, Germany.
Cutter Bladespt	Cr12MoV steel with quenched treatment, hardness HRC58~61, wear-resistance, good steel structure, long life.

Component and Function:

Coil Feeding Equipment	Consists of one uncoiler with capacity of 3 tons and its base. The steel sheet is manually fed to the guiding equipment under the function of friction and traction.
Infeed Guide	Adopting guiding bar and sliding block (sheet lubricator) to control the width and position of the steel sheet. The coil sheet is guided in the correct position and passed to the roll forming equipment.
Mainframe Transmission	Transfer the main motor power to the rollers through cardan gear, and also transfer the coil sheet.rrect position and passed to the roll forming equipment.
Roll Forming Station-	The main frame of machine is welded separately and the outside wall is connected by screw after being roto blasted on the surface. The rollers are surface-chrome plated after being machined by the exact machine tool. The tooling is PLC precision machined and supported with pre-lubricated rolling contact bearings.
Rectifying Device	Used upper 2 rollers and lower 3 rollers, to rectify the straightness of the panel after roll formed.Â
Post-cut Equipmentn>	Stationary hydraulic post shear/guillotine. The length and quantity of pieces can be set by the buyer through the control console, when reach the set length, the machine will cut the panel automatically. The cutting is finished under the power of hydraulic station which guarantees the precision of cutting.
Hydraulic Station	Supplies the initial power to the cuter through a closed oil tank. It is off without cutting, which can save the power.
PLC Control Console	The electric controlling system of this machine consists of five parts: operating system, touch screen, PLC, transducer and strong electricity parts. The controlling system of this machine is imported from Siemens Company of Germany. The system uses modularized structure and has convenient, reasonable, canonical wiring arrangement, and its maintenance is quite easy. The independent operating console facilitates the mutualdialogue between the operator and the machine. The operation is easy and steady and can be chosen operation by manual or automatically.
Product Support Table	To support the finished run out panels. The quantity we supply is 2 pieces with length 2 meters; it can support panels with more than 4 meters in normal condition.

Excavator Cylinder Piston Rod Seals

Installation and application of piston rod seal for excavator hydraulic cylinder
The installation and application of hydraulic cylinder piston rod seals in excavators mainly include the following aspects:
1. Applying lubricating oil: Before installing the seal, the surface of the piston rod must be coated with lubricating oil to facilitate the installation and use of the seal.
2. Install the seal: Install the seal on the piston rod in sequence, taking care not to pinch or bend the seal.
3. Pressing the seal: After installing the seal, special tools need to be used to press the seal tightly to ensure its tightness and stability.
4. Check the sealing effect: After installing the sealing element, it is necessary to check the sealing effect. It can be detected by observing the working status of the hydraulic cylinder or using tools such as leak detectors.
5. Application scenario: The piston rod seal of excavator hydraulic cylinder is mainly used in the hydraulic system of construction machinery such as excavators, loaders, and bulldozers to prevent hydraulic oil leakage and ensure the normal operation of the machine.
In summary, the installation and application of hydraulic cylinder piston rod seals in excavators is a very important part of the hydraulic system, and must be strictly operated in accordance with regulations to ensure the normal operation and safety of the machine.
