Problems solved by technology

[0003] Due to the roughness of the flat ribbed wall products formed by extrusion, casting and milling through the mold, it is difficult to meet the three-dimensional finned heat exchange plate used in special occasions; even the raised fins made by brazing , but there are some contact gaps in the welds, which are easy to accumulate dirt and increase the contact thermal resistance, which reduces the heat transfer efficiency of the rib wall

Embodiment 1

[0053] The cutting equipment of the three-dimensional finned heat exchange plate is described as follows.

[0054] Three-dimensional finned heat exchange plate cutting equipment, such as Figure 1 to Figure 6 As shown, it includes the main body of the machine tool mainly composed of the bed 1, the bed guide rail 2 and the bed head box 3 arranged on the bed guide rail 2. The bed head box 3 is driven by the main motor and the reduction box. A drive mechanism and a crank link mechanism connected to the output end of the drive mechanism are provided. One end of the crank link mechanism is connected to the drive mechanism, and the other end is connected to the input end of the cutter bar 5. The drive mechanism and the crank link mechanism jointly push the cutter bar 5 in a horizontal position. Do reciprocating motion in the direction; a cutter 4 is provided at the output end of the cutter bar 5, and a feed mechanism 8 is arranged on the cutter 4. The cutter tooth 403 of the cutter ...

Embodiment 2

[0070]With reference to embodiment 1, select the cutting tool of cutter tooth 403 wedge angle θ=63 ° for use, its machining process is: first workpiece 6 is fixed on the first supporting plate 11, confirms that the lower surface of workpiece 6 and the upper surface of first supporting plate 11 Start the vacuum pump after the surface fits well, open the vacuum switch to make the vacuum chamber 13 form a vacuum, check the vacuum degree of the vacuum gauge, and check the stability and reliability of the workpiece 6 and the first supporting plate 11; The tool 4 is at the retraction limit; adjust the position of the tool feed mechanism 8 so that the tool 4 completely withdraws from the slope of the inclined block 804; adjust the parallelism between the chisel edge line of the cutter tooth 403 and the upper surface of the workpiece 6, and check with a feeler gauge, the error ≤0.03mm; if image 3 and Figure 6 As shown, the angle of the cutter tooth 403 is adjusted so that an includ...

Abstract

The invention provides a three-dimensional fin heat exchange plate machining process. The three-dimensional fin heat exchange plate machining process mainly comprises the steps of material selection,unloading, clamping and cutting: (1) material selection: a metal plate with the cutting machinability and good ductility is selected as a basal body plate; (2) unloading: the basal body plate in the step (1) is premachined as a workpiece with a thickness of not less than 0.5 mm; (3) clamping: the workpiece in the step (2) is positioned on three-dimensional fin heat exchange plate cutting equipmentfor positioning; and (4) cutting: the three-dimensional fin heat exchange plate cutting equipment is started for cutting to obtain a three-dimensional fin heat exchange plate. The machining process is adopted to machine three-dimensional fin heat exchange plates with fins staggered on flat plate workpieces and 20-90 included angles between the fins and the horizontal plane; and through special configuration, fluids passing through the surfaces of the fins can form streaming flows, crossing flows, turbulent flows or mixed flows, so that the fluids are low in resistance and excellent in transparency, and the heat exchange efficiency of the heat exchange plates can be greatly improved.

Description

technical field [0001] The invention relates to a processing technology of a heat exchange plate, in particular to a processing technology of a three-dimensional fin heat exchange plate. Background technique [0002] Existing flat ribbed wall products (heat exchange plates) are usually provided with raised / protruding warps on the surface of the substrate (the raised / protruded warps are also called fins), and the manufacturing method is one One is to form protruding warps on the surface of the flat substrate by extruding, casting, etc. through a mold; The warped piece. [0003] Due to the roughness of flat ribbed wall products formed by extrusion, casting and milling through molds, it is difficult to meet the three-dimensional finned heat exchange plates used in special occasions; even the raised fins made by brazing , but there are some contact gaps in the welds, which are easy to accumulate dirt and increase the contact thermal resistance, which reduces the heat transfer ...
