Abstract
The utility model relates to steel pipe processing equipment, title is expander mould and the pipe expander of bimodulus, the expander mould of bimodulus, comprise expander die ontology, expander die ontology has axle core segment, described axle core segment presents front end and is truncated cone-shaped structure, is cylindrical structural to also have a restrictive coating at the skin of described axle core segment, form columnar gap between described restrictive coating and axle core segment below; Pipe expander, comprise base, base has and stretches out projection, projection is provided with expander mould, described expander mould comprises expander die ontology, expander die ontology has axle core segment, described axle core segment presents front end and is truncated cone-shaped structure, is cylindrical structural below, a restrictive coating is also had at the skin of described axle core segment, form columnar gap between described restrictive coating and axle core segment, the expander mould of such bimodulus and pipe expander have more smooth, the more smooth advantage in the outside of the product of production.
Description
Technical field
The utility model relates to steel pipe processing equipment, specifically relates to expanding die tool, also relates to pipe expander.
Background technology
Pipe expander comprises base, base has and stretches out projection, and projection is provided with expander mould, and base also has slidably pipe clamp; In prior art, the structure of the inside of wanted expander only assigned by expander mould, do not support limiting part in the outside of wanted expander, and such pipe expander has expanded steel pipe outside easily wave, irregular shortcoming.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned shortcoming, the expander mould providing a kind of outside of product more smooth, more smooth and pipe expander---the expander mould of bimodulus and pipe expander.
The technical scheme of the utility model expander mould is achieved in that the expander mould of bimodulus, comprise expander die ontology, expander die ontology has axle core segment, described axle core segment presents front end and is truncated cone-shaped structure, is cylindrical structural below, it is characterized in that: also have a restrictive coating at the skin of described axle core segment, between described restrictive coating and axle core segment, form columnar gap.
The technical scheme of the utility model pipe expander is achieved in that pipe expander, comprise base, base has and stretches out projection, projection is provided with expander mould, described expander mould comprises expander die ontology, and expander die ontology has axle core segment, and described axle core segment presents front end and is truncated cone-shaped structure, is cylindrical structural below, it is characterized in that: also have a restrictive coating at the skin of described axle core segment, between described restrictive coating and axle core segment, form columnar gap.
The beneficial effects of the utility model are: the expander mould of such bimodulus and pipe expander have outside more smooth, the more smooth advantage of product of production.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model pipe expander.
Fig. 2 is the A-A cross-sectional view in Fig. 1.
Wherein: 1, axle core segment 2, restrictive coating 3, gap 4, base 5, projection 6, expander die ontology.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1, 2, the expander mould of bimodulus, comprise expander die ontology, expander die ontology has axle core segment 1, described axle core segment presents front end and is truncated cone-shaped structure, is cylindrical structural below, it is characterized in that: also have a restrictive coating 2 at the skin of described axle core segment, between described restrictive coating and axle core segment, form columnar gap 3.
As shown in Figure 1, 2, pipe expander, comprise base 4, base has and stretches out protruding 5, projection is provided with expander mould, and described expander mould comprises expander die ontology 6, expander die ontology has axle core segment 1, described axle core segment presents front end and is truncated cone-shaped structure, is cylindrical structural below, it is characterized in that: also have a restrictive coating 2 at the skin of described axle core segment, forms columnar gap 3 between described restrictive coating and axle core segment.
Like this, during expander, owing to there being the restriction of lateral sheathed layer, the product expanded will reduce waviness phenomena, has advantage of the present utility model.
The foregoing is only specific embodiment of the utility model, but architectural feature of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the change done or modification are all encompassed in the scope of the claims of the present utility model.
