Steel Sheet Making Machine

Steel Sheet Making Machine

Machine Features:

Our roofing sheets machine is composed of a decoiler, a feeding and levelling device, a pre – shear, a roll forming system, a hydraulic post – cutting mechanism, a run-out table, a hydraulic station, and a PLC (controlling system).

It can produce standard products with a yield strength reaching up to 450Mpa. The long production line ensures that the final products have an excellent profile shape. This machine is both time – saving and labor – saving, greatly enhancing production efficiency, making it highly suitable for current production requirements. Moreover, it is user – friendly, operates stably, and offers high precision.

2) The thickness range of the coil that is appropriate: 0.4-0.5mm
3) The raw materials that are suitable for use: color steel sheet
4) The yield strength possessed by the raw material: 245Mpa

Main Components:

1. Hydraulic decoiler with coiler car
a. De-coiler: It is a hydraulic de-coiler.
b. Control type: Controlled by electric buttons.
c. Function: It can automatically rotate and feed the sheets into the next station.
d. Weight of the de-coiler: The de-coiler weighs 1 Ton.
e. Motor Power: The motor has a power of 3Kw, operates at 380V, and 50Hz (customization options are available).

2. Hydraulic pre-cutting system

a. Function: It is employed to cut the head and tail parts of the material.
b. Feature: It is equipped with a tail material reminder function.

3. Roll-Forming M/C:

a. Main Frame: The main frame of the machine is individually welded. After undergoing surface rot blasting, the outer wall is joined together with screws.
b. Roller Material: The roller is made of high-quality No.45 forged steel and processed through digital control techniques.
c. Roller Shafts: The shafts of the rollers are processed by a grinding machine twice to ensure the precision of the final product.
d. Roller Surface Treatment: Once precisely machined by the machine tool, the rollers have a 0.05mm-thick hard chrome plating on their surface. This effectively extends the service life of the forming rollers.
e. Shaft Diameter: The diameter of the shafts is 75mm or 95mm.
f. Number of Profile Forming Rollers: There are 18 stations of profile forming rollers.
g. Transmission and Drive: The production line is moved by a combination of chain and gear, which is powered by a motor.
h. Control System: All working operations are automatically controlled by the PLC electric cabinet.
i. Power Voltage: The suitable power voltage is 380V, 50Hz, three-phase (customization is available).
j. Working Speed: The working speed of the line (forming speed) is approximately 20m/min (excluding the cutting time).
k. Main Machine Motor Power: The power of the main machine motor is around 7.5KW.

4. Hydraulic Post Cutting

a. Cutting Mode: It adopts post cutting method, and the machine will stop during the cutting process.
b. Cutting Blade Material: The material of the cutting blade is Cr12, which has undergone quenched treatment.
c. Frame Structure: A welded frame is adopted, ensuring good rigidity.
d. Treatment of Cutting Frame: The cutting frame has been heat treated to prevent the deformation of the final product. The tolerance of the cutting length is ±2mm.

5. Hydraulic station:

a. Function: It provides the power source for the hydraulic cutter.
b. Accessories Brand: All the hydraulic accessories are either renowned Chinese brands or imported well-known brand products.
c. Oil Pump Power: The power of the oil pump in the hydraulic station is 5.5 KW.
d. Servo Motor and Drive Components: The power of the follow servo motor is 5.0KW, which is of the Inovance brand. It uses a linear guide and a ball screw for driving.

6. Profile Stack

a. Power Feature: It is un-powered.
b. Quantity: There are a total of 3 units.
c. Design Feature: Each stack has rollers on the top, which facilitates easy movement.
