A kind of processing method of water meter shell

Abstract

The invention relates to a processing method for a water meter casing, which includes the following steps: step S1: cutting, cutting out a positioning ring and a sealing sheet with a plate, cutting out a water inlet pipe and a water outlet pipe with a pipe material, and cutting out a water inlet pipe and a water outlet pipe with a pipe material, and using the outer walls on both sides The main body of the watch case is cut out of the pipe with flanged holes symmetrically on the upper side, and the flanged holes are all flanged to the outside of the pipe; Step S2: Welding. The main body of the watch case is welded; then the sealing sheet is welded to the main body of the watch case; step S3: grinding, and the welding seam between the water inlet pipe, the water outlet pipe, the sealing sheet and the main body of the watch case is polished in sequence. Flanged holes are set on both sides of the main body of the watch case. When the water inlet pipe and outlet pipe are welded to the main body of the watch case, the welding position will no longer be close to the main body of the watch case, so that there is enough space for welding tools and grinding tools. It is convenient to use for welding and grinding, which will not only make the welding effect better but also reduce the damage of grinding to the main body of the watch case.

Description

technical field [0001] The invention relates to the technical field of water meter manufacturing, in particular to a processing method for a water meter casing. Background technique [0002] There are many ways to manufacture the water meter shell. In the early days, the water meter shell was mostly cast iron or brass, but now it is mostly made of steel plate or steel pipe through stamping and welding. [0003] At present, the Chinese patent with the notification number CN209589168U discloses a water meter watch case, which includes a watch case main body, a water inlet pipe and a water outlet pipe. The watch case main body is provided with a water inlet and a water outlet. The water outlet is connected. The main body of the watch case is provided with a positioning ring for placing the water meter movement. The water inlet and the water outlet are misplaced. The positioning ring just separates the water inlet and the water outlet. The lower end of the watch case body is al...

AI Technical Summary

Problems solved by technology

[0004] The above existing technical solutions have the following defects: the connection between the water inlet pipe and the water inlet and the connection between the water outlet pipe and the water outlet are all welded, and for the convenience of welding, welding will be performed from the outer surface of the watch case body, and the welding Finished leaving a noticeable weld seam on the outer surface of the case body

Since the position to be welded is close to the main body of the watch case and is blocked by the water inlet or outlet pipe, it is very inconvenient for both the welding work and the subsequent polishing of the weld seam, which affects the production efficiency of the water meter case
