Detailed Description

The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the utility model but are not intended to limit the scope of the utility model.

Referring to fig. 1 and 2, the low-pressure oil pipe end forming device of the utility model comprises a lower pressing die 1 and an upper pressing die 2 attached to the top end of the lower pressing die 1, wherein the same side of the lower pressing die 1 and the upper pressing die 2 is respectively provided with a convex plate 5 for supporting a pipeline, the lower pressing die 1 and the upper pressing die 2 are respectively provided with a cavity, the two cavities are in butt joint fit with each other, and the lower pressing die 1 and the upper pressing die 2 are respectively provided with a positioning through hole;

the positioning through hole is adhered with a hole expanding component 3 and a forming mechanism for processing parts, the end of the oil pipe is pre-expanded through the hole expanding component 3, and then is formed and processed through the forming mechanism;

through the aforesaid, the staff places the work piece that needs processing on the circular slot of lower moulding die 1 earlier, later with last moulding die 2 and the top laminating of lower moulding die 1 together again, later the staff carries out the reaming to the work piece through reaming subassembly, the staff reuses forming mechanism after the reaming is accomplished and makes the work piece shaping, thereby the oil pipe end accords with another oil pipe's type form completely, make two oil pipe weld carrying out more easily, reduce welding deformation, effectual assurance product quality, and because the welding position between two parts laminates completely, make the leakproofness between two parts better, thereby promote holistic practicality.
