Embodiment Construction

[0022] A processing method for a pipe joint, the pipe joint includes an integrally extruded upper joint 7, a lower joint 9 and a hexagonal sleeve 8, which includes the following process steps:

[0023] The first step is to simultaneously extrude the inner chamfer 1 and outer chamfer 3 of the lower end of the round steel cut to length through the mold; the chamfer of the workpiece is extruded at the lower end, which is convenient for extrusion and easier to form , and the inner chamfer and outer chamfer are extruded at the same time, and the efficiency is relatively high.

[0024] In the second step, turn the workpiece 180° and go to the next mold, extrude the inner chamfer, outer chamfer and arc groove 2 at the other end through the mold; turn the workpiece 180°, and also make the chamfer at the other end of the workpiece The corners are extruded at the lower end, which is convenient for extrusion and easier to form, and the inner chamfer, outer chamfer and arc-shaped groove a...

Abstract

The invention relates to the technical field of workpiece machining, in particular to a pipe joint machining process method which comprises the following process steps that 1, an inner chamfer and an outer chamfer at the lower end are formed through extrusion; 2, an inner chamfer, an outer chamfer and an arc-shaped groove at the other end are formed through extrusion; 3, a large cylindrical groove is formed through extrusion, and meanwhile, the outer wall of a workpiece is extruded and shaped, so that the whole workpiece is lengthened; 4, a hexagonal sleeve is formed through extrusion; 5, a small cylindrical groove and a conical sealing groove are formed through extrusion, and meanwhile the outer wall of the lower portion of the hexagonal sleeve is extruded to be conical; and 6, the conical sealing groove and the small cylindrical groove are made to achieve penetrating in an extrusion mode, and meanwhile the workpiece is subjected to extrusion shaping. The pipe joint machining process method provided by the invention is low in cost and less in material consumption, machining excess materials are not generated, and the machined workpiece is high in strength and precision.

Description

technical field [0001] The invention relates to the technical field of workpiece processing, in particular to a processing method for pipe joints. Background technique [0002] As a connecting piece between the pipelines, the pipe joint is provided with joints at both ends and a hexagonal sleeve in the middle for easy connection. The traditional pipe joints are processed by turning, which needs to select round steel with a diameter larger than the hexagonal sleeve as the raw material for cutting. This processing method not only consumes a lot of materials and costs high, but also produces a lot of waste, which has an impact on the environment, and the mechanical properties of the processed workpieces are relatively poor, and it is easy to produce processing errors. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pipe joint processing method with low cost, less consumable materials, no processing residue, and r...
