Copper pipe inner wall blow-drying device

Abstract

The invention discloses a drying device for the inner wall of a copper pipe, which comprises a blowing tube, the rear end of the drying tube is processed with an external thread, the front end of the drying tube is in the shape of a cone, and the front end of the vertical drying tube is equipped with a pressure Tighten the screw, the rear end of the drying cylinder is connected to the compression pump through the external thread and tightened by the nut, the cone at the front end of the drying cylinder is inserted into the copper pipe and tightened by the compression screw. The cylinder wall of the drying cylinder is punched with a hole, and a hex nut is welded on the hole, and the jack screw is assembled in the nut and rotates downward to compress the cylinder wall. The invention has the advantages of simple structure, firm butt connection and no air leakage, thereby improving production efficiency.

Description

technical field [0001] The invention relates to a drying device, which is especially suitable for drying the inner wall of copper pipes. Background technique [0002] When the copper pipe is rolled, the water content in the inner wall of the copper pipe needs to be blown dry when the head and tail of the copper pipe undergo secondary cooling. Enter the compressed air to dry the copper tube. Since the drying device is not firmly connected with the end of the copper tube, air leakage is easy to occur, resulting in incomplete drying of the inner wall of the copper tube, which affects the downstream processing of the copper tube. Contents of the invention [0003] The task of the present invention is to propose a blow-drying device which can completely dry the moisture in the inner wall of the copper pipe and improve the product quality. [0004] The task of the present invention is accomplished in this way, which includes a drying cylinder, characterized in that: the rear en...
