Abstract

The invention belongs to the technical field of forming machining of spiral baffle plates of shell-and-tube heat exchangers, and particularly relates to a machining method of spiral baffle plates. The method comprises the following steps that S1, a spiral baffle plate compression forming die is manufactured; S2, compression molding of the spiral baffle plates is conducted; and S3, hole site machining of the spiral baffle plates is conducted. According to the machining method of the spiral baffle plate, spiral baffle plate parts are formed through cold pressing forming, heat treatment shaping and overall assembly drilling, the surface forming is smooth, the screw pitch size meets the requirement, and the hole site size of the spiral baffle plates and the hole site concentricity between the spiral baffle plates meet the requirement. The spiral baffle plate compression forming die not only can be used as a forming die, but also can be used as a heat shaping die and a spiral baffle plate assembly hole site drilling tool, so that the process feasibility, the forming quality and the processing efficiency are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of forming and processing spiral baffles for shell and tube heat exchangers, and in particular relates to a processing method for spiral baffles. Background technique [0002] Shell-and-tube heat exchangers occupy an important position in chemical industry, petroleum, power, nuclear energy utilization and other industrial fields. They have the advantages of simple structure, high heat transfer coefficient, high pressure resistance, and easy cleaning. The traditional arcuate baffle heat exchanger is the most commonly used, but this type of baffle has frequent changes in the fluid flow direction on the shell side and is prone to leakage, which leads to a large pressure drop on the shell side of the heat exchanger and is prone to In addition, if the shell-side flow rate is large, it is easy to induce the vibration of the heat exchange tube and shorten the service life of the heat exchanger. [0003] In view of...
