Automatic PU Sandwich Panel Production Line Sheet Metal Roll Forming Machines

Automatic PU Sandwich Panel Production Line Sheet Metal Roll Forming Machines

1. Technical parameters of PU sandwich panel product line

This PU sandwich panel production line is an automatic production line. In the PU sandwich panel producing procedure, the product line can continuously produce sandwich panel with PU as its core material. The liquid state raw materials were continuously injected into the middle of two steel panels and reacting, foaming, solidifying in the double-rubber belt, the PU sandwich panel could be cut out automatically according to the required length for users.

It consists of 5 tons automatic uncoiler, chain driven transmission, 2 sets of roll former, PU foaming machine, PU panel conveyor, non-stop cutting device, electric controlling system.

● Production material: (0.3-0.6mm)*L
● Production speed: 4-8m/min
● Production type: totally continuous production with PLC
● PU foam thickness: 30mm, 40mm, 50mm, 80mm
● Composite structure: position fixed by double rubber tracker
● Foaming system: totally automatically continuous foaming, quantity of foaming could be step-less adjustable
● Total power: 50 KW
● Cutting: band saw
● Electronic controlling system: PLC controlling system

2. Specification detail

● Two sets of uncoiler: it is automatic and hydraulic, can be used to uncoil steel coil which is maximal 1300mm wide, 5 ton and steel coiler's inner diameter is about 500mm

● Two sets of roll forming machine
a. Function: roll forming for the profiles of PU panel
b. Use the welding H-beam, motor driver, sprocket chain driving
c. Technical data: material of roller is 45# forged steel, with CNC processing, plated with hard chrome on surface of forming rollers

● Two sets of conveyor rack: up conveyor is about 24m, down conveyor is about 30m, they lead the steel sheet from the roll forming machine to preheating room and to foaming, to cutting.

● One preheating room: it is built by heat-insulation material, and it could heat up the steel sheet to 25-38 by heater

● One set of PU two component liquid mixing and injecting section for foaming: it adopt Chinese high pressure pump, it has the temperature control system and material-level monitoring system, the tank of the material is about 150L, two tanks, this section is showed in the photo

● Foaming and double rubber device include motor driver system to make panel, the width of belt board is 1250mm, the range of adjusting distance between upper and lower frame belt board: min 25mm, max 200mm, and the range of adjusting thickness of sandwich panel: 50mm, 75mm, 100mm (50mm and 75mm for celling, 100mm for wall)

● Panel automatically cutting system
a. Cutting machine can move 2500mm longitudinally along product line
b. Fly saw of the cutting machine can move transversely 1900mm, cutting machine moves longitudinally and transversely along the slide way
c. Cutting machine adopts one-side blade band saw manner, cutting and revolving after cutting, the cutting saw can revolve, so cutting in two directions is realizable
d. There is panel tight-pressing system (pneumatic) in the cutting machine
e. There is location limiter to limit longitudinal and transverse motion of cutting machine

● Electric control system
a. The control system adopt the touch screen, PLC, module control and transducer, the control system adopt Panasonic (JAPAN) product
b. There one control platforms and electric trunk by which operating and controlling the electric motors and all motions (including hydraulic and pneumatic) in the product line
c. Intercalated appropriate amount of portable switch on the product line, so manual operation get convenient
d. Alarm and emergency stop system should be installed in the product line in case accident happens

3. Working flow

Uncoiler loading → Adjustable feeding guide → Steel panel forming → Steel sheet feeding guide → PU foaming → PU panel conveyor → Non-stop cutting

        Friendship Machinery is a world leader in automatic welding machine for steel fabrication field and industrial pipeline construction projects, providing an extensive range of equipment for a variety of project applications.

        Year after year, automatic welding systems from Friendship Machinery are designed, tested, used, and continuously upgraded in every type of environment. Our customers enjoy industry-leading repair rates that are constantly improving: from less than 5% in 2001 to less than 2% in 2012.

        The performance record of our specially designed and manufactured automatic welding machine is the backbone of Friendship Machinery's reputation. The proven ability of every set machine is why customers have returned to us repeatedly for new applications, designs and machinery as their products change and expand. We are proud of that fact.

        Our main products: H&I beam welding line, T beam welding line, box column beam line, CNC multi-head plate cutting line, beam assembly machine, straightening equipment, steel pipe welding line, shot blasting machine, CNC flame/plasma cutting equipment, welding assisting machinery incl. Welding manipulator, welding positioner, turning roll (welding rotator), Membrane wall panel production line, which are widely used in many industries like aerospace, petrochemical, metallurgy, shipbuilding, chemical equipment, boiler pressure vessels, steel structure construction, etc.

        Since 1990s, the market for steel structure building industry boomed. With fast development, very short period for construction and beautiful external appearance, as well reasonable price was occupied in the market of building industry. We invest more on developing roll forming machine such as Metal roof &wall panels machines, C&Z purlin machines drywall Stud-track forming machines , Metal decks machines , No- girder and Column curves forming machines, Guard rails forming machines , Downspout pipes forming machines and so on.
