Distribution Transformer Oil Tanks’ Corrugated Fin Wall made of Cold Rolled SPCC Steel Sheet.
What is Cold Rolled SPCC Steel Sheet?
Cold Rolled SPCC Steel Sheet full name is Cold Rolled Steel Plate Cold Commercial Steel Sheet.
What is the Production Process of Cold-Rolled Sheet? And its grades.
The Cold Rolled Sheet manufacturing processes:
- Hot rolling
- Cold rolling
Common grades of Cold-rolled Sheet:
In China sheet grades:Q195A-Q235A,Q195AF-Q235AF,Q295A(B)-Q345A(B)
In Japan sheet grades:SPCC,SPCD,SPCE
In Germany sheet grades: ST12,ST13,ST14,ST15,ST14-T
In Euro sheet grades: DC01, DC03,DC04,DC05,DC06,DC07
What is the Metal Sheet Common Bending Methods:
Sheet metal bending parts are often used as key components such as structural parts, brackets and shells in various products such as electro-mechanical, household appliances, automobiles, aircraft, instruments and communication equipment.
The sizes and shapes of sheet metal bending parts for different purposes vary greatly, and the production batches are also different, so the bending processes used are different.
For large-size plate-like pure bending parts (section thickness is 0.5-3 mm), such as electronic control box, micro-computer control table and worktable, the processing of thin plate bending and folding formed parts, generally using folding machine and sheet bending press for automobile manufacturing 8 bending forming panels (section thickness is 0.9-1.5 mm) and skeleton parts (material thickness is 1.2-2.5 mm), in order to meet mass production and high quality. Quantity requirements are usually made with large stamping dies.
Cold bending is used to test the ability of material to withstand bending deformation. It reflects the plasticity of sheet and strip from the side. Cold bending test is often used in the process performance test of sheet and strip. Usually when the specimen is bent to 180, the bending position of the specimen is checked. The cold driving test sample has no cracks or delamination defects. The cold bending properties of sheets and strips with good processing properties at room temperature must be qualified.
Bending is the basic process of stamping. It is a stamping process that bends the flat blank (sheet, profile, pipe, bar, etc.) or semi-finished product into a certain angle and fixed curvature under the action of bending moment according to the design requirements, forming the required shape parts. Bending methods are classified according to the equipment used, which can be divided into press (ordinary press), stretch bending (stretch bending machine), roll bending (roll bending machine) and bending (bending machine).
The Corrugated Fin Wall made by folding the Cold Rolled SPCC Steel Sheet to got folded Fin part.
The Steel plate thickness: 1-1.5mm,Steel plate width: 300-1300mm, Feed by JTFY Hydraulic Decoiler to Automatic Corrugated Fin Wall Folding Machine. The Clamping mold platens lock and form the metal sheet to corrugated fins. Then use JTFY Automatic Welding machine to weld fins seams to got finished part.
