Automatic roll forming equipment for flat-top rectangular wave heat exchange fin

Abstract

The present invention provides automatic roll forming equipment for a flat-top rectangular wave heat exchange fin. The automatic roll forming equipment comprises a strip tension guide unit (200), a first roller mold unit (201), a second roller mold unit (202), and a third roller mold unit (203), a fin shaping unit (204), the fin counting and cutting unit (205), and a fin outlet turning guide unit(206). The automatic roll forming equipment for the flat-top rectangular wave heat exchange fin adopts at least two forming steps. In the automatic roll forming equipment provided by the invention, the size and length changes of a product can be adjusted by only programmatically changing parameters; the width change of the fin can be adjusted by increasing or decreasing the number N of paired roller molds; the fin pitch and wave height changes can be adjusted by only replacing the paired roller molds; and each transmission and control drive system is unchanged. The mechanical adjustment and program adjustment of the entire transmission control system of the equipment system can adapt to the continuous production of heat radiating fins of various sizes and models, which greatly improves theproduction efficiency, also greatly improves the efficiency of model change and lowers the cost of various sizes of mold opening.

Description

technical field [0001] The invention relates to the technical field of automatic roll forming, in particular to an automatic roll forming equipment for flat-top rectangular wave heat exchange fins. Background technique [0002] Automotive water-to-air coolers, oil coolers, water or oil liquid medium heat exchange fins have a large contact area and liquid medium flow needs, and are designed as two adjacent flat-top rectangular wave fins with a 1 / 4 pitch that are offset from each other. The heat dissipation fin has a thin substrate and a small wave height, forming positive and negative transverse grooves, which is conducive to the turbulent flow of liquid, and at the same time forms a large heat exchange area. Its flat top approximates the top of the rectangular wave to maximize the brazing contact area. The heat transfer efficiency is very high in the liquid medium of water or oil. Traditionally, this type of heat dissipation fin requires multi-step stamping and forming, and...
