Example Embodiment

[0014] The present invention will be described in detail below with reference to the drawings and specific embodiments: the port sealing process of the heating container of the electric water heater according to the present invention. It is to prepare an ordinary machine tool with three chucks and a rotation speed greater than 500 rpm, and prepare an arc-shaped tool with no blade edge. figure 1 As shown, the copper tube 1 is clamped on the machine tool with a clamp, and a bladeless tool 2 with an arc-shaped edge at one end is used. The tip 3 of the bladeless tool 2 is used to slowly squeeze the high-speed rotating copper tube port 4 edge, the port of the red copper tube 1 performs point-to-surface squeeze friction with the front end of the bladeless tool during high-speed rotation to generate high temperature, and the port of the red copper tube is retracted inward by using the extension feature of the red copper; After the port of the copper pipe is closed inward, a new port is...

Abstract

The invention relates to a port sealing process of a heating container of an electric water heater, which comprises the following steps: first clamping a fixture for a red copper tube on a machine tool, adopting an edge-less cutter with an arc-shaped side on one end, slowly extruding the edge of the port of the red copper tube which rotates at high speed with the front end of the edge-less cutter so that the port of the red copper tube produces high temperature when rotating at high speed and having point-surface extrusion friction with the front end of the edge-less cutter, and enabling the port to close up inwards with the extension, pressing and stretching characteristics of red copper; forming a new port after the port of the red copper tube closes up inwards, extruding the new port with the arc-shaped end of the edge-less cutter, and so on, keeping closing up inwards until the port is gradually reduced and finally sealed in the center; and the port sealing process of the heating container of the electric water heater has the advantages of simple process, no seam and no welding, can well prevent welding and the oxidation of high-temperature melting points, can achieve attractive overall appearance, and is characterized by higher compressive strength, longer service life and the like.

Description

technical field [0001] The invention relates to a port sealing process for a cup-type heating container of an instant electric water heater, and belongs to the technical field of mechanical manufacturing processes. Background technique [0002] At present, the cup-type heating container (also known as the heating cup container) of the instant electric water heater is generally made of metal materials such as stainless steel, aluminum alloy or red copper, and its shape is mainly cylindrical and a small amount of rectangle. The ports at both ends of this heating cup container are welded by gas welding or argon arc welding to weld the stamped cover and cylinder. The high temperature causes the metal to oxidize easily. In order to overcome the problems of this welding process, Germany's Sibao Yachuang Electric Water Heater Co., Ltd. adopts a welding-free connection technology, which uses the flange of the cylinder port and the flange of the impacted cover, and then flanges the ...
