Problems solved by technology

Most of the existing pipe fittings and flanges are fixed by welding or threaded connection. The welding not only needs to fix each other, but also takes up the construction time on site. For the threaded connection, thread tapping must be performed on the connecting side of the flange and the pipe fitting in advance. When installing on site, the flange must be turned hard to make the connection with the pipe fittings stable, which is time-consuming and laborious, which is not conducive to the rapid butt joint installation of pipe fittings

Embodiment 1

[0085] see Figure 1 to Figure 20 As shown, the present invention provides a pipe fitting and flange manufacturing process and assembly method, comprising the following steps:

[0086] 1. The original flange grooving stage:

[0087] S1, first fix the original flange on the outer end surface of the fixed disc 211 on the side of the slotting seat 101 on the processing equipment for pipe fittings and flanges;

[0088] S2. Then insert the tail end of the turning tool 234 into the knife hole 233, and tighten the handle 235 on the top of the slider 220, and then push the slider 220 toward the fixed disc 211 until the front end of the turning tool 234 is aligned with the circle of the original flange. Protrude the middle part of the ring, and then tighten the rocker 235 on the fixing table 224 to make the slider 220 stable;

[0089] S3, then start the grooving motor 210 to make it work, and drive the fixed disc 211 to drive the original flange to rotate synchronously, and then rota...

Abstract

The invention discloses a pipe fitting and flange manufacturing technology and assembling method which comprises the following steps: at first, carry out annular groove cutting and slot milling on anoriginal flange, then, drilling a positioning hole in an original pipe fitting, subsequently, simultaneously drilling the processed original flange and the original pipe fitting, inserting a locatingpin in a positioning hole of a formed pipe fitting, mounting a cylindrical pin in a limiting hole of a formed flange, and finally, carrying out butt joint and rotary installation on the formed pipe fitting and the formed flange. According to the pipe fitting and flange manufacturing technology and assembling method, a grooving mechanism and a groove milling mechanism are adopted to carry out annular groove turning and slot milling on the original flange, a drilling mechanism is adopted to drill a positioning hole in the original pipe fitting, and then, synchronous drilling is carried out on the grooved flange and the original pipe fitting. The structure is simple, operation is easy, batch production is facilitated, and the processed formed pipe fitting and the formed flange are in butt joint and rotate, so that the cylindrical pin protrudes out of the fixing hole of the formed pipe fitting, and the processed formed pipe fitting and the formed flange are rapidly mounted in a butt jointmanner to further accelerate the onsite mounting progress.

Description

technical field [0001] The invention relates to the technical field of pipe fitting processing, in particular to a manufacturing process and assembly method of pipe fittings and flanges. Background technique [0002] Flange is also called flange plate, which has a ring structure and a ring protrusion in the middle, which is used for the butt joint of pipe fittings. There are holes near the edge of the flange, and the two flanges are tightly connected by passing through the bolts, so that the butt pipe fittings communicate. The flanges are sealed with gaskets. Most of the existing pipe fittings and flanges are fixed by welding or threaded connection. The welding not only needs to fix each other, but also takes up the construction time on site. For the threaded connection, thread tapping must be performed on the connecting side of the flange and the pipe fitting in advance. Tooth, on-site installation must turn the flange to make it firmly connected with the pipe fittings, w...
