Abstract

The utility model discloses a forming device for an irregular tube of an elliptical tube. The forming device comprises an upper mold base, a lower mold base, an upper semi-elliptical concave mold and a lower semi-elliptical concave mold, wherein the upper semi-elliptical concave mold and the lower semi-elliptical concave mold are respectively fixed on the upper mold base and the lower mold base; an upper semi-irregular concave mold is positioned inside the upper semi-elliptical concave mold and is capable of sliding; a lower semi-irregular concave mold is positioned inside the lower semi-elliptical concave mold and is capable of sliding; convex mold fixing plates are respectively arranged on two corresponding sides of the lower semi-elliptical concave mold; two convex molds in arc match with the small end of an elliptical tube are respectively fixed on two convex mold fixing plates through convex mold connecting plates and screws. The middle part of the irregular tube machined by using the forming device takes the shape of an irregular tube, two ends of the irregular tube take the shape of an ellipse, the shape is regular, and the material is saved.

Description

The building mortion of elliptical tube anomaly pipe

technical field:

This practical type is relevant with the water main in gas heater, special relevant with the building mortion that elliptical tube is processed into shape tube.

background technology:

Also do not have at present in the middle of elliptical tube is processed into is the shaped device of elliptoid elliptical tube change special pipe for special-shaped tubulose, two ends.

utility model content:

The purpose of this utility model be for provide a kind of elliptical tube is processed in the middle of for special-shaped tubulose, two ends are oval tubulose, shape rule, save the building mortion of the elliptical tube anomaly pipe of material.

The purpose of this utility model is achieved like this:

The building mortion of the utility model elliptical tube anomaly pipe, comprise upper bolster, die shoe, be separately fixed at upside of ellipse die, second oval die on upper and lower die holder, first special-shaped die is positioned at upside of ellipse die and can slides, second special-shaped die is positioned at second oval die and can slides, second oval die two corresponding sides are equipped with respectively punch retainer, and two punch that coordinate with elliptical tube small end circular arc are fixed on two punch retainers by punch connecting plate and screw respectively.

In the utility model when work,, the punch of elliptical tube to be deformed being put into upper and lower semiellipse die Jian，Jiang two ends pushes elliptical tube small arc-shaped portion, then by external force by upper and lower half special-shaped die matched moulds, elliptical tube is configured as shape tube.Just in time contrary during release, first exit upper and lower special-shaped die, then exit the punch at two ends.

Thereby the utility model building mortion directly becomes elliptical tube interlude into different form is processed into shape tube, guarantee that special-shaped position shape and size are accurate, product quality is good, can reduce the loss of copper material simultaneously.

the specific embodiment:

Referring to Fig. 1, Fig. 2, the building mortion of the present embodiment elliptical tube anomaly pipe, comprises upper bolster 1, die shoe 2, is separately fixed at upside of ellipse die 3, second oval die 4 on upper and lower die holder.First special-shaped die 5 is positioned at upside of ellipse die and can slides.Second special-shaped die 6 is positioned at second oval die and can slides.Second oval die two corresponding sides are equipped with respectively punch retainer 7.Two punch 8 that coordinate with elliptical tube 15 small end circular arcs are fixed on two punch retainers by punch connecting plate 9 and screw 10 respectively.

Referring to Fig. 3, Fig. 4, first the special-shaped die in the utility model, second special-shaped die, two punch are connected with the piston rod being contained in upper cylinder 11 on lathe side plate 16, lower oil cylinder 12, left oil cylinder 13, right oil cylinder 14 respectively.During work, by the flexible of the piston rod in each oil cylinder, elliptical tube is processed into the shape tube as shown in Fig. 5～Fig. 7.

Claims

1. the building mortion of elliptical tube anomaly pipe, it is characterized in that comprising upper bolster, die shoe, be separately fixed at upside of ellipse die, second oval die on upper and lower die holder, first special-shaped die is positioned at upside of ellipse die and can slides, second special-shaped die is positioned at second oval die and can slides, second oval die two corresponding sides are equipped with respectively punch retainer, and two punch that coordinate with elliptical tube small end circular arc are fixed on two punch retainers by punch connecting plate and screw respectively.
