Manufacturing method of heat exchanger plate

Abstract

The invention discloses an optimal design method of a heat exchanger plate, which comprises the following steps of: according to the parameter requirements and the restriction conditions on the heat exchanger plate, setting up a material database for a material forming performance test; setting up a die model and a standard sample database; simulating the punching process of the heat exchanger plate, comparing with the standard sample database and analyzing the defects of the plate in a simulating and punching process to judge whether the simulating result accords with a test specification ornot, if not, adjusting the topological structure of a die and the geometric dimensions of the local positions, and then carrying out analysis and a simulation test again until the simulating result completely accords with the test specification; outputting various parameters of the die corresponding to the heat exchanger plate with the simulating result according with the test specification; and manufacturing the die. The optimal design method integrates the two steps of trial-producing a sample plate and reforming the die in the traditional method into a digital manufacturing link, thereby reducing the blindness in design, avoiding the scrapping of the die and shortening the development cycle of the heat exchanger plate.

Description

technical field [0001] The invention belongs to the technical field of mechanical design and manufacture, and relates to a method for manufacturing heat exchanger plates. Background technique [0002] Heat exchanger plates are widely used in heat exchangers, air coolers, air preheaters, evaporators and other equipment in petrochemical, aerospace, thermoelectric nuclear power, food and pharmaceutical industries. With the enlargement of equipment, many problems have appeared in the processing and manufacturing of heat exchanger plates, such as serious thinning, cracking, warping and other forming defects in parts of the plates, and the decline in the forming quality of heat exchanger plates, resulting in As the frequency of mold repairs increases, the probability of mold scrapping also increases. [0003] At present, the design of heat exchanger plates still adopts the traditional design method, that is, through the stages of plate design, mold design, mold manufacturing, tr...

AI Technical Summary

Problems solved by technology

However, in the stage of mold transformation, due to the excessive reliance on the experience and skills of the operator and the lack of necessary technical support, there is a large blindness, and a little carelessness may cause the mold to be scrapped.

At the same time, it is necessary to repeatedly trial-produce prototypes and modify molds, resulting in an extended development cycle for heat exchanger plates
