Description

Technical Field

[0001] This utility model relates to the field of sheet metal forming technology, and in particular to an integrated sheet metal forming system. Background Technology

[0002] Currently, the domestic fiber cement board and fiber cement tile industry mainly uses two forming methods: sheet forming and flow forming. Sheet forming utilizes the pressure difference between the inside and outside of a rotating screen wheel in a wire mesh box to filter the slurry suspension, forming an initial layer on the screen wheel which is then transferred to the felt. After dewatering, the slurry is continuously wound onto a forming cylinder and compacted to obtain the blank. Sheet forming production lines have high production capacity and produce boards with a smooth surface, but they cannot be used to produce high-end boards such as those with full-body color. Flow forming utilizes a headbox to evenly spread the slurry suspension onto a running felt, forming a continuous slurry layer. After dewatering, the slurry is continuously wound onto a forming cylinder and compacted to obtain the blank. Flow forming production lines can produce all types of boards, but the surface smoothness is lower than that of sheet forming.

[0003] In summary, existing sheet forming machines cannot be used to produce high-end sheet materials such as solid-body sheets. Existing flow forming machines produce sheets with relatively poor surface flatness, lower strength with the same formula, and lower output. If a factory needs to produce different types of products or expand its production capacity, it needs to add new sheet forming or flow forming production lines, requiring a larger factory area and more equipment costs.

[0004] Therefore, there is an urgent need for an integrated sheet metal forming system to solve the aforementioned problems in the existing technology. Utility Model Content
