AI Technical Summary

Technical Problem

During efficient tube processing, fins are prone to tear, resulting in burrs forming, reducing fin height and heat exchange efficiency.

Method used

A pre-hardening device and method are used to pre-harden the high-efficiency tube through the propulsion rod and the pre-treatment assembly to ensure that the fins are not easy to tear during the process and avoid burrs.

Benefits of technology

Through pre-pressure and hardening treatment, the fin forming height is improved, the overall heat exchange efficiency of the efficient tube is improved, the burr formation is reduced, and the fins are not easily tear.

Abstract

The present invention discloses a device and method for pre-pressing and hardening a high-efficiency tube, wherein the device for pre-pressing and hardening a high-efficiency tube comprises: a push rod, the outer diameter of which matches the inner diameter of the high-efficiency tube; the push rod extends from one end of the high-efficiency tube to the inside thereof; a pre-treatment assembly, comprising a pre-treatment roller and a pre-treatment driver, the outer surface of the pre-treatment roller abuts against the outer surface of the high-efficiency tube, and the pre-treatment roller is parallel to the axis of the high-efficiency tube; the pre-treatment driver can drive the pre-treatment roller to perform circular motion along its axis; a tube driver is connected to the high-efficiency tube and is used to drive the high-efficiency tube to perform circular motion along its axis. The present invention performs pre-pressing and hardening treatment before finning to ensure that the fin is not easily torn during the process of finning and to avoid the generation of burrs.
