Technical Field

The invention relates to the technical field of sealing gasket stamping equipment, in particular to a stamping system for producing and processing a sealing gasket of a plate heat exchanger and a stamping method thereof.

Background

The plate heat exchanger is a high-efficiency heat exchanger formed by stacking a series of metal sheets with certain corrugated shapes. Thin rectangular channels are formed between the various plates of the plate heat exchanger, and heat exchange is carried out through the plates.

The plate heat exchanger is an ideal device for heat exchange of liquid-liquid and liquid-vapor. The heat exchanger has the characteristics of high heat exchange efficiency, small heat loss, compact and light structure, small occupied area, wide application, long service life and the like.

Under the condition of the same pressure loss, tests show that the heat transfer coefficient of the plate heat exchanger is 3-5 times higher than that of the tubular heat exchanger, the occupied area of the plate heat exchanger is one third of that of the tubular heat exchanger, and the heat recovery rate can reach more than 90%.

The detachable plate heat exchanger is formed by punching a plurality of corrugated thin plates at certain intervals, sealing the peripheries of the corrugated thin plates by gaskets, overlapping and pressing by using a frame and pressing screws, forming fluid distribution pipes and fluid collection pipes by four corner holes of the plates and the gaskets, and reasonably separating cold and hot fluids to enable the cold and hot fluids to respectively flow in flow channels on two sides of each plate so as to carry out heat exchange by the plates.

The gaskets referred to above are of various specifications, and annular gaskets are more commonly used. The most adopted method for processing the annular sealing gasket is to stamp the whole rubber. However, this stamping method is liable to cause severe deformation of the gasket.

Some sealing gaskets are produced by adopting a pouring mode, specifically, pouring is carried out on a grooving mold, and the sealing gasket is taken out from a groove after the sealing gasket is formed, but the mode also has some problems, for example, the sealing gasket is easy to be adhered to the bottom of the groove and is not easy to be taken out; the sealing gasket is not poured uniformly, so that the thickness error is large.

Therefore, the inventor designs a stamping system for producing and processing a sealing gasket of a plate heat exchanger and a stamping method thereof, which are used for solving the problems.
