Description

Radial extrusion pipe end flaring machine

Technical Field

The utility model relates to a pipe end flaring machine, in particular to radial extrusion pipe end flaring machine.

Background

The diameter of the end opening of the steel pipe needs to be enlarged, and the end opening of the steel pipe is generally formed by spinning flaring and axial die pressing flaring. The existing spinning flaring method is that a pipe rotates at a high speed and rubs with an extrusion head, so that the pipe end deforms after generating high temperature, the molecular structure of a material of the pipe end can change after flaring, heat treatment is needed, and the material structure is readjusted. The axial mould pressing flaring adopts a forming mould to axially extrude the port to expand the pipe port, the clamping force for fixing the pipe must be larger than the axial thrust of the mould, and for the thin-wall pipe, the larger clamping force is easy to cause the deformation of the pipe.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a radial extrusion pipe end flaring machine to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a radial extrusion pipe end flaring machine, includes hydro-cylinder, piston rod and flaring die, piston rod one end is installed on the hydro-cylinder, the piston rod is kept away from hydro-cylinder one end and is connected with polygon tapered wedge, the piston rod pushes polygon tapered wedge axial displacement under the oil cylinder drive, the flaring die is installed in the polygon tapered wedge outside, still be provided with the mould guide way on the flaring die, the flaring die is along mould guide way radial movement under the drive of polygon tapered wedge.

As a further improvement to the technical scheme, the oil cylinder is a hydraulic oil cylinder.

As a further improvement to the above technical solution, the polygonal wedge shape is a hexagon.

As a further improvement to the above technical solution, the outer diameter of the flaring die increases when the flaring die moves along the radial direction of the die guide groove.

As a further improvement to the technical scheme, the oil cylinder, the polygonal tapered wedge and the central shaft of the flaring die are on the same horizontal line.

The utility model discloses a technological effect and advantage: the utility model discloses a radial extrusion pipe end flaring mode, the enlarged portion of pipe does not generate heat, does not change the material structure, and the flaring is fast, and power is low, the energy can be saved, and the pipe end enlarges the size range and realizes automated control easily.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides a radial extrusion pipe end flaring machine as shown in figures 1-3 comprises an oil cylinder 1, a piston rod 2, a polygonal tapered wedge 3 connected with the piston rod 2, a flaring die 4 and a die guide groove 5.

It should be further noted that the oil cylinder 1 is pushed by hydraulic pressure, the piston rod 2 pushes the polygonal wedge 3, the polygonal wedge 3 can move axially, and due to the axial movement of the polygonal wedge 3, the flaring die 4 can be driven to move radially along the die guide groove 5, so that the outer diameter of the die guide groove 5 is increased, and the port of the pipe is expanded.

What need explain at last is the utility model provides a pair of radial extrusion pipe end flaring machine adopts radial extrusion pipe end flaring mode, and the enlargement part of pipe does not generate heat, does not change the material structure, and the flaring is fast, and power is low, the energy can be saved, and the pipe end enlarges the size range and realizes automated control easily.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
