Integrated fireproof rolling door section mill

Abstract

The invention relates to an integrated fireproof rolling door section mill which comprises a bilayer blooming sheet mill (1), a sheet combining positioner (3), an edge rolling mill (4) and a base (5). The bilayer blooming sheet mill (1), the sheet combining positioner (3) and the edge rolling mill (4) are sequentially mounted on the base (5) along a section moving direction; the integrated fireproof rolling door section mill further comprises a fireproof material rolling frame (2) which is detachably mounted on the base (5) and arranged between the bilayer blooming sheet mill (1) and the sheet combining positioner (3). The integrated fireproof rolling door section mill has the advantages of compact structure, convenience in use, saving of labor cost, high production efficiency and stable product quality.

Description

technical field [0001] The invention relates to the technical field of fireproof rolling door production, in particular to an integrated fireproof rolling door profile rolling mill. Background technique [0002] At present, most of the fire-resistant rolling door panels on the market are filled with fire-resistant materials in the hollow double-layer metal sheet. The cross-sectional shape diagram of the product is shown in Figure 4 shown. Since the double-layer metal sheet is a strip material, it is especially suitable for cold bending. The traditional production steps of double-layer metal sheet are as follows: ① Separately roll out such as Figure 5 The strip-shaped metal sheet with the cross-section shown is cut off according to the required length (reserving the length required for the subsequent cutting head); ②Put fireproof material in the groove of one section, and buckle another section on the fireproof material Initially rolled strip metal sheet; ③ use a spot wel...

Problems solved by technology

[0003] However, the above-mentioned production method has the following disadvantages: the steps ②, ③, and ④ need to be manually operated, not only the number of workers is large, the labor intensity is high, and the efficiency is low. Slippage) the upper and lower two initial rolling metal sheets, otherwise the product quality cannot be guaranteed

When crimping on the hinged rolling mill, due to the relative slippage of the upper and lower sheets, the solder joints are torn, which may also affect the product quality

And because spot welding is required, it is necessary to increase spot welding equipment and increase investment costs

Coupled with the subsequent head cutting process, the number of cuts increases, which is time-consuming and material-intensive, seriously affecting production efficiency
