Embodiment Construction

[0016] The present invention will be further described below in conjunction with accompanying drawing:

[0017] Depend on figure 1 to combine figure 2 As shown, the sealing process steps of the metal pipe port are as follows:

[0018] a. The metal pipe 1 is clamped in the elastic collet that can rotate on the machine tool, and a positioning part 2 is inserted into the elastic collet. The metal pipe 1 is set outside the positioning part 2. There is a certain distance between the end faces of the metal pipe 1;

[0019] b. Adopting the edgeless cutter 3 with the extruding surface 4 at the end, the extruding surface 4 can make the port of the metal pipe 1 gradually deform towards its center, and utilize the edgeless cutter 3 to extrude the metal pipe 1 rotating at high speed The heat generated by the friction between the port of the metal tube 1 and the edgeless tool 3 softens the port of the metal tube 1, and the port of the metal tube 1 slowly gathers towards the center, an...

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...
