Embodiment Construction

[0026] The present invention and its beneficial effects will be further described in detail below in conjunction with the accompanying drawings.

[0027] Such as Figure 1 to Figure 3 Shown is a method for measuring the gap between plate forming molds for plate heat exchangers. This method uses soft metal materials to be placed at the gaps to be detected by the mold to be tested. After the mold is closed, the soft metal material deforms. By measuring the deformation of the soft metal To judge the clearance of the mold under test, it includes the following steps:

[0028] Step 1. Cut the lead wire or tin wire of soft metal material into several small pieces, prepare soft metal samples, and place 1 to 12 test points on the inner surface of the lower mold of the mold test point. The test points are evenly, comprehensively and symmetrically distributed. on the inner surface of the die;

[0029] Step 2. Sample forming. After placing the soft metal sample properly, close the upper...

Abstract

The invention relates to the technical field of production auxiliary equipment detection of plate type heat exchangers, and discloses a measuring method for the mold clearance of plate molding of a plate type heat exchanger. According to the method, characteristics of low hardness of soft metal materials, good liquidity during extrusion, and extremely small resilience after molding are employed, lead wires or tin wires of the soft metal materials are cut into a plurality of sections and prepared to soft metal samples arranged on the internal surface of a lower mold of mold test points, the test points are uniformly, comprehensively, and symmetrically distributed on the internal surface of the lower mold, a proper pressure is applied to the samples on a hydraulic press for pressing, the mold clearance is filled by the soft metal materials, the mold clearance is calculated by employing the thickness of the molded soft metal, and the actual mold clearance of a calendaring mold can be accurately detected. The test method is simple, the precision of the measuring result is high, the consumption of the soft metal materials is low, and the detection cost is lowered; besides, the hardness of the soft metal materials is low so that the molding pressure is low, the damage to the internal surface of the mold is prevented, and the service lifetime of the mold is extended.

Description

technical field [0001] The invention relates to the technical field of detection of auxiliary equipment for production of plate heat exchangers, in particular to a method for measuring gaps between plate forming molds of plate heat exchangers with simple detection methods, low cost and high accuracy of measurement data. Background technique [0002] At present, the application fields of plate heat exchangers are expanding, and the application conditions of plate heat exchangers are becoming more and more stringent, and the formed plates of plate heat exchangers are one of the most critical parts of plate heat exchangers, so how to Improving the precision of forming plates in plate heat exchangers has become a major issue in the plate heat exchanger industry. [0003] The formed plates of plate heat exchangers are usually pressed and formed by materials such as stainless steel, titanium plates, nickel plates, etc. The thickness of the plates is generally between 0.4mm-0.9mm. ...
