Process for sealing port of metal pipe

Abstract

The invention relates to a process for sealing the port of a metal pipe. The problems of low processing efficiency and low yield in the current method for sealing the port of the metal pipe fitting can be mainly solved. The process is characterized by comprising the following steps of: a, clamping the metal pipe (1) in an elastic jacket capable of rotating on a machine tool, wherein a locating piece (2) extends in the elastic jacket; and the metal pipe (1) is sleeved outside the locating piece (2); b, extruding the port of the metal pipe (1) which rotates at high speed by using a cutter (3) without a blade till the port of the metal pipe (1) is completely closed and molten integrally at high temperature; and c, flat turning the metal pipe (1) by using a turning tool, closing the outer end face of the port, chamfering and then polishing. According to the process for sealing the port of the metal pipe disclosed by the invention, the port of the metal pipe is sealed through one-time tooling by using the machine tool; the process is simple, low in cost, high in processing efficiency and high in yield; no welding line exist; and the appearance is flat and smooth.

Description

technical field [0001] The invention relates to a sealing method for a metal pipe port, in particular to a sealing process for a metal pipe port. Background technique [0002] When producing bathroom hardware pendants (hereinafter referred to as pendants), in order to meet the requirements of performance and aesthetics, it is necessary to seal the ports of metal pipe fittings. The material of the pendant is generally made of copper, stainless steel, aluminum alloy, zinc alloy and other metals that are not easy to rust. When sealing the end of the pipe fitting in the pendant, welding is generally used, and the end of the pipe is blocked by the head, and polished after welding , polishing, this method has the following defects: 1. auxiliary materials such as welding wire or electrode, flux, oxygen, liquefied gas are required during welding, the cost is high, and processes such as grinding and polishing are also required after welding, and the process is cumbersome and complica...
