Abstract
The invention provides a gas tube joint of a gas meter and a machining process of the gas tube joint. The joint comprises a head end, a middle section and a tail part which are connected sequentially; and an outward turnup edge is arranged on the outer surface of the tail part. The machining process comprises the following steps of: heating a 20# material at a middle frequency; manufacturing a blank by using a 100-ton punching machine; punching by using a 35-ton punching machine; turning a rough blank of the tube joint; rolling screw threads; performing finish-machining by using a numerically controlled lathe; performing surface treatment (coating colored zinc) so as to obtain the finished gas tube joint of the gas meter; and pressing the gas tube joint into a gas meter shell. The gas tube joint of the gas meter is easy to assemble and the machining process is easy to implement; and by the machining process, the material is saved, the machining time is short, and the machined gas tube joint is firm and durable.
