Abstract

The invention relates to the field of heat exchangers, and discloses a device and method for reducing machining deformation of a heat exchange fin. The device comprises a base, a supporting plate and a vacuumizing device, wherein the supporting plate is arranged above the base, and a plurality of pipelines are arranged on the supporting plate; one end of each pipeline is flush with the plate face of the supporting plate, and the other end of each pipeline extends out of the supporting plate and is hermetically connected with the vacuumizing device. The method comprises the following steps of: (1) conducting finishing treatment on a heat exchange fin blank before machining; (2) mounting the device for reducing machining deformation of the heat exchange fin, placing the heat exchange fin blank on the supporting plate, connecting the pipelines to the vacuumizing device, and starting the vacuumizing device; (3) conducting milling machining of pouring cooling liquid on the heat exchange fin blank; and (4) after milling is completed, closing the vacuumizing device, conducting vacuum breaking, and taking down the part. The device solves the problem that the heat exchange fin is very easy to deform during clamping and machining is effectively solved, and has the advantages of being easy to operate and low in cost.

Description

technical field [0001] The invention belongs to the field of heat exchangers, and more specifically relates to a device and method for reducing processing deformation of heat exchange fins. Background technique [0002] As the main component of the plate-plate heat exchanger, the heat exchange fin has high heat exchange efficiency, small footprint, multiple forms, flexible assembly, convenient disassembly, cleaning and maintenance, and is widely used in various industries such as electric power, petroleum, chemical industry, air conditioning, etc. . However, since it is a thin-walled part, mostly made of aluminum alloy, it is easily deformed during clamping and processing, resulting in a high reject rate during processing, which brings great difficulties to manufacturing. With the continuous improvement of processing requirements, it is difficult for the existing clamping tools to meet the processing requirements, and most of the processing methods used to reduce the deform...
