Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of heat exchangers, and in particular to a device for corrugated roll forming of heat exchanger plate surfaces. Background Technology
[0002] Plate heat exchangers are currently an indispensable piece of equipment in industrial heat transfer processes. They are widely used in chemical, petroleum, steel, automotive, food, and light industries, and are also an important component of air conditioning and heating systems.
[0003] Existing heat exchanger plate surface corrugated roll forming devices, such as the plate heat exchanger plate roll forming device disclosed in utility model patent application number 201520249389.3, mainly include an unwinding mechanism, a film coating mechanism, a shearing mechanism, a roll forming mechanism, and a conveying mechanism. After the rolled plate is unwound by the unwinding mechanism, a film is applied to the surface of the plate by the film coating mechanism, and then the plate is cut by the shearing mechanism. The cut plate is then conveyed to the roll forming mechanism by the conveying mechanism for pressing. In use, the upper and lower pressure rollers are provided with matching protrusions and grooves on their circumferential surfaces. The upper and lower pressure rollers rotate in opposite directions around their respective axes. The cut plate passes between the upper and lower pressure rollers, forming a pressed texture under the action of roller pressure.
[0004] However, most existing roll forming equipment has a narrow range of applications, making it difficult to roll sheets of different sizes. Moreover, the synchronization between the upper and lower rolls is poor, which can easily affect the rolling effect and even cause the sheets to crack. Utility Model Content

[0012] Preferably, the tooth depth of the lower and upper shaping rollers located at the rear is greater than that of the lower and upper shaping rollers located at the front; through stepped rolling, the corrugated tooth depth of the sheet can be gradually increased to the final shape, thus avoiding sheet breakage.
