Feeding device and method for heat exchanger sheet forming

Abstract

The invention discloses a feeding device and method for heat exchanger sheet forming. The device comprises a PLC installed on an electric control cabinet near a machine frame, and an automatic feedingmechanical hand system, a conveying mechanism, a conveying positioning system, a sheet stretching die, an automatic taking stacking system which are installed on the machine frame in sequence from left to right. The automatic feeding mechanical hand system is used for sucking heat exchanger sheet semi-finished products and transferring the semi-finished products to the conveying mechanism, the conveying mechanism is used for transferring the heat exchanger sheet semi-finished products to the conveying positioning system, the conveying positioning system is used for aligning the heat exchangersheet semi-finished products and transferring the semi-finished products to the sheet stretching die, and the sheet stretching die is used for stretching the heat exchanger sheet semi-finished products. The feeding device and method have the advantages that automation of the feeding work procedure, the conveying work procedure, the positioning work procedure, the stacking work procedure and the like for the plate type heat exchanger stainless steel sheet semi-finished products is achieved, production efficiency is improved, the traditional labor intensive production way is changed, and a guarantee is provided for large-batch production and industrial production.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a feeding device and a feeding method for forming heat exchanger plates. Background technique [0002] The plate heat exchanger is a high-efficiency heat exchanger composed of a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat exchange is performed through the plates. Plate heat exchanger is an ideal equipment for liquid-liquid, liquid-vapor heat exchange. It has the characteristics of high heat exchange efficiency, small heat loss, compact and light structure, small footprint, wide application and long service life. In the case of the same pressure loss, its heat transfer coefficient is 3-5 times higher than that of the tube heat exchanger, and the floor area is one-third of that of the tube heat exchanger, and the heat recovery rate can be as high as 90%. [0003] At present, the produ...

Problems solved by technology

[0003] At present, the production method of plate heat exchangers is a labor-intensive manual traditional production method in which the semi-finished stainless steel plate is stretched and formed by manually controlling the hydraulic press. This method requires workers to work under the hydraulic press, which is not only dangerous but also The work intensity of workers is also relatively high, which seriously restricts production efficiency and factory pass rate
