Pipe fitting grooving machine and grooving processing technique for end of pipe fitting

Abstract

The invention relates to a pipe fitting grooving machine and a grooving processing technique for the end of a pipe fitting. The pipe fitting grooving machine comprises a grooving processing assembly and a pressing wheel power component, wherein the grooving processing assembly comprises a main shaft, a motor, a knurling wheel, a pressing wheel shaft, a pressing wheel frame and a pressing wheel; the lower end of the main shaft is connected to the power output end of the motor; the upper end of the main shaft is provided with the knurling wheel; the pressing wheel is arranged on one side of theknurling wheel; the pressing wheel is connected to the pressing wheel frame through the pressing wheel shaft; and the pressing wheel frame is driven by the pressing wheel power component. The pipe fitting grooving machine and the grooving processing technique for the end of the pipe fitting solve the problems that the pipe fitting is prone to be detached from the knurling wheel in the grooving process on three-way elbows and other pipe fittings by existing pipe fitting grooving processing equipment and techniques, and that the end of the pipe fitting is prone to be scratched during processingbecause the variation of the distance from a groove to the end of the pipe fitting is great. The pipe fitting grooving machine and the grooving processing technique for the end of the pipe fitting arecapable of effectively controlling the variation of the distance from the groove to the end of the pipe fitting, improving the processing quality, and preventing the end of the pipe fitting from being scratched during processing. The pipe fitting grooving machine and the grooving processing technique for the end of the pipe fitting also have the advantages of precise and controllable groove processing depth of the pipe fitting, reasonable functional layout of equipment and the like, and are especially suitable for the grooving processing for the ends of special-shaped pipe fittings such elbows.

Description

technical field [0001] The invention relates to a device and a process for processing grooves on metal tubular products, in particular to a pipe fitting rolling groove machine and a rolling groove processing technology for the end of the pipe fittings. Background technique [0002] At present, during the laying of pipelines (such as steel pipes), pipe fittings such as tee elbows are often used when the pipeline path needs to be changed. These pipe fittings need to be connected by clamps, and the clamp connections need to be grooved on the ends of the pipe fittings. Although the current technology for rolling grooves on straight pipes is relatively mature, the current technology for rolling grooves on pipe fittings such as tee elbows is not perfect, such as figure 1 Shown: The problems usually encountered are the large variation of the distance A between the groove of width B and the end of the pipe fitting, and the end of the pipe fitting is easy to scratch during processing...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a pipe fitting grooving machine and the grooving processing technology for the end of the pipe fittings, which mainly solves the problem that the existing pipe fitting grooving processing equipment and technology are easy to run when the existing pipe fitting grooving processing equipment and technology are grooving on pipe fittings such as tee elbows (i.e. : the pipe fitting breaks away from the knurling wheel), the distance from the groove to the pipe fitting end varies greatly, and the pipe fitting end is easily scratched during processing; the device and process of the present invention can effectively control the distance from the groove to the pipe fitting end It also has the advantages of accurate and controllable pipe groove processing depth, reasonable equipment function layout, etc., and is especially suitable for the end of special-shaped pipe fittings such as elbows.
