Description

Technical Field

[0001] The utility model relates to the field of chemical mechanical equipment, and more particularly to an automatic processing device for tetrafluoro tie rods. Background Art

[0002] A heat exchanger is an energy-saving device that realizes heat transfer between materials among two or more fluids at different temperatures. It enables heat to be transferred from a fluid at a higher temperature to a fluid at a lower temperature, so that the fluid temperature reaches the specified index of the process, to meet the needs of process conditions. At the same time, it is also one of the main devices for improving energy utilization efficiency. The heat exchanger industry involves nearly 30 industries such as heating ventilation, pressure vessels, medium water treatment equipment, chemical industry, and petroleum.

[0003] For a plate condenser, it consists of a glass-lined bottom, cover, double-sided glass-lined sandwich concave-convex plates, nitrile rubber gaskets, U-shaped rubber hoses, and fasteners, etc., in an overlapping assembly structure. Especially for enameled or tantalum alloy plate condensers that require corrosion prevention, the fasteners connecting the sandwich concave-convex plates also need to have anti-corrosion characteristics. Based on economic considerations, stainless steel is usually used. However, for austenitic stainless steels such as 201 / 304, etc., they will be corroded when the solution contains hydrochloric acid or aqua regia; for 316L stainless steel with stronger corrosion resistance, it will be corroded when the solution contains a mixed acid of concentrated phosphoric acid, concentrated sulfuric acid, and fluorosilicic acid at a certain temperature. Therefore, the scope of application of fasteners made of stainless steel is limited.

[0004] Considering the above reasons, fasteners made of tetrafluoro are used to fix the sandwich concave-convex plates. Tetrafluoro is the abbreviation of polytetrafluoroethylene, which has the characteristics of being acid and alkali resistant, resistant to various organic solvents, almost insoluble in all solvents, and having high strength.

[0005] For the processing of fasteners, 1. The ends need to be cut into specified sizes; 2. One end needs to be drilled and then internal threads are processed; 3. The other end needs to be processed for the outer diameter and then external threads are processed. The previous method was as follows: first, manually cut the required length, and then mount it on a CNC lathe for processing: turning the outer diameter and processing the external threads; disassemble and re-clamp the head, drill holes, and process the internal threads. There are the following defects in single processing: manual cutting results in a large length error of the tie rod; during the processing, the coaxiality of the disassembled and replaced outer diameter and hole is relatively low; the processing efficiency is low and the processing accuracy is poor.
