Description

Technical Field

[0001] The invention relates to the technical field of cold bending processing, in particular to a stainless steel plate material forming production device. Background Art

[0002] Existing stainless steel plate composite materials, such as decorative skirting, include a skirting inner layer and a stainless steel skirting decorative outer layer laminated on the outside of the skirting inner layer. Such decorative connecting strips are generally formed by cold bending (unwinder - laminating machine - forming machine - cutting machine - blanking rack) to form the stainless steel plate into a decorative connecting strip profile. This production method and process is not a problem for producing decorative strips with a panel width of more than 40mm and using stainless steel with a thickness of more than 0.42mm, because a sufficiently thick stainless steel plate has sufficient rigidity. During the composite transmission process, even if the transmission force is slightly uneven during transmission, it will not cause surface unevenness. However, if Figure 5 As shown, when producing decorative strips with a panel width of more than 40mm, if the thickness of the stainless steel plate used is 0.24 or 0.3mm or even thinner, it is easy for the stainless steel plate to have low rigidity, resulting in unevenness during the composite transmission process. After composite, the composite stainless steel panel will produce wavy patterns and other phenomena, which cannot meet the quality requirements of the product. Of course, the above situation will also occur when producing a single stainless steel bent profile. Summary of the Invention

[0003] The object of the present invention is to provide a production device for forming stainless steel plates or stainless steel strip materials, which can ensure that the panel of the stainless steel product will not produce ripples or the like, and meet the requirements of product quality flatness, even when producing decorative strips with a panel width of more than 30 mm and the thickness of the stainless steel material used is 0.42 mm or even thinner.

[0004] The present invention is implemented in this way, which includes an unwinding machine, a film laminating machine, a leveling machine, a cold roll forming machine, a straightening machine, a cutting machine, and a blanking rack. The cold roll forming machine includes a frame, a plurality of forming roller groups arranged on the frame, and a transmission accessory arranged on the frame. The unwinding machine unwinds the stainless steel plate or stainless steel strip and guides it to the film laminating machine. After the film laminating machine laminates the surface of the stainless steel material, it guides the filmed stainless steel material into the leveling machine. (The function of the film laminating is to protect the stainless steel surface from being easily scratched and to improve the surface cleanliness. The appearance of the stainless steel product after the film laminating is more beautiful and more high-end. If the stainless steel plate or stainless steel strip The material already has a film attached to it, so it does not need to go through the film laminating machine process. It can be directly unwound and introduced into the leveling machine.) When the stainless steel material passes through the array of upper and lower structure pressure rollers in the leveling machine, the stainless steel material is straightened and stretched by controlling the pressure of the upper and lower pressure rollers. After being straightened, the stainless steel material enters the cold roll forming machine. The cold roll forming machine array forming rollers gradually bend the two sides of the stainless steel material into shape. The formed stainless steel decorative connecting strips are straightened by the straightening machine and sent to the cutting machine to be cut into segments. The segmented stainless steel decorative connecting strips are then introduced into the unloading rack for transfer and storage.

[0005] Since this process adopts the straightening stretching technology of the leveling machine, the stainless steel plate or stainless steel coil material with uneven surface or wavy surface caused by factors such as uneven transmission tension and pressure or low rigidity of the material itself during the processing will be straightened. The surface of the straightened material is straight and has no wavy lines. When it is then introduced into the cold bending forming process, wavy lines will not be generated due to the uneven surface of the stainless steel material, thereby ensuring the quality of the product.

[0006] Compared with the existing technology, the present invention has the advantage of ensuring that the processed product panel is flat and free of ripples, etc., even when producing decorative strips with a panel width of more than 30 mm and the thickness of the stainless steel plate or stainless steel coil used is 0.42 mm or even thinner, thereby meeting the product quality requirements.

The primary cold roll forming machine 404 cold-bends the stainless steel material into a groove shape (such as a U shape), and the groove-shaped stainless steel material is introduced into the plastic profile delivery machine 405. Then, the plastic profile a is delivered into the groove-shaped stainless steel material b of the plastic profile delivery machine 405. Then, the groove-shaped stainless steel material b is introduced into the terminal cold roll forming machine 406 together with the plastic profile a to complete the final cold bending wrapping molding.
