Embodiment Construction

[0026] 1. Plate pressing (by figure 1 , 2 , 3, 4, 5)

[0027] The plate pressing process is realized by the pressing die, and the pressing die includes an upper template 1, a lower template 2, a guide post 3, a guide sleeve 4, a punch insert 5, a die insert 6, an inner Hex bolt 9, pin 10. The splicing of the convex and concave mold inserts 5 and 6 takes the angle of the gasket groove and the angle of the corrugation as the parting surface, and the pressing die also includes a blank holder 7 and a polyurethane binder block 8. When pressing, the blank holder 7 first Press the periphery of the plate tightly, and then press the corrugated mold. A plurality of polyurethane binder blocks 8 are arranged between the lower template 2 and the blank holder ring 7. When pressing, there is a certain pressing force first, and then press down to form. Make the surface stretched evenly after processing.

[0028] 2. The overall blanking of the plate (by Image 6 , 7 , 8, and 9)

Abstract

The invention relates to a processing method of sheets of a heat exchanger, in particular to a manufacture method of sheets of a V-shaped plate heat exchanger. The method is realized by two process steps including sheet compression and integral blanking of sheets. In the invention, the whole process for manufacturing the sheets can be realized just by adopting two working procedures; the sheets have flat surfaces, no easy distortion and high assembly precision; in addition, the purposes of reducing consumption, saving investment, lightening the labor intensity of workers and improving the quality of product can be realized.

Description

technical field [0001] The invention relates to a processing method for a plate of a heat exchanger, in particular to a method for manufacturing a plate of a V-shaped plate heat exchanger. Background technique [0002] Since the plate heat exchanger has been developed for more than a century, with the deepening of people's understanding of it, various plate heat exchangers and new plate types have come out continuously. It has the characteristics of high efficiency, energy saving, and convenient maintenance. With continuous expansion, the plate heat exchanger industry has developed rapidly. Subsequently, the processing technology of the plate, the main part of the plate heat exchanger, is constantly being updated and facing new challenges. Whether the plate processing technology is good or bad directly affects the performance and product quality of the plate heat exchanger. As early as the 1960s and 1970s, the processing of plates still used the traditional processing tech...
