Abstract

The utility model relates to a one-step forming mould for a double-convex ring at the end of a metal pipe. The one-step forming mould is characterized by comprising an upper mould body, a lower mould body and a side mould body, sliders sliding in grooves are arranged in the grooves in the side parts of the upper mould body and the lower mould body, channels for pressing the metal pipe are formed in the upper mould body, the lower mould body and the sliders, and pits are formed in the side surface of the side mould body. The one-step forming mould for the double-convex ring at the end of the metal pipe is simple in structure and reasonable in design, and can be used for processing and forming the double-convex ring at the end of the metal pipe in one step, thereby simplifying the procedures and improving the processing efficiency.

Description

Metal tube termination double convex ring one-time-shaped mould
Technical field:
The utility model relates to a kind of metal tube termination double convex ring one-time-shaped mould.
Background technology:
Metal tube is to realize by the socket mode with being connected of plastic tube, more firm in order to be socketed connection, usually be provided with double convex ring (as shown in Figure 1) in the metal tube termination, having what process in the metal tube termination that this double convex ring adopts now is fashion of extrusion, a bulge loop is finished a station extruding, two bulge loops namely need to be finished at two stations, and production efficiency is low.
Summary of the invention:
The purpose of this utility model is to provide a kind of metal tube termination double convex ring one-time-shaped mould, and this metal tube termination double convex ring one-time-shaped mould is simple in structure, reasonable in design, is conducive to the disposable double convex ring that is processed to form the metal tube termination.
The utility model metal tube termination double convex ring one-time-shaped mould, it is characterized in that: comprise upper and lower die body and side form body, be provided with the slipping block of slippage in the groove body in the groove body of described upper and lower die body sidepiece, be provided with the conduit that compresses metal tube at upper and lower die body and slipping block, described side form body side surface is provided with depression.
Be provided with spring between above-mentioned slipping block and the groove body.
Above-mentioned depression is the rounded depression in cross section, is provided with the taper platform in concave bottom.
The operation principle of the utility model metal tube termination double convex ring one-time-shaped mould, metal tube to be processed is placed on the lower mold body, metal tube end slightly has one section to be exposed at outside the lower mold body, upper die body presses down, conduit is fixed metal tube, the side form body action, advance toward the metal tube termination from side direction, this depression is namely pushed and is exposed at the outer metal tube end of lower mold body (namely form first bulge loop at metal tube end this moment), the side form body continues to advance, squeeze and push away slipping block, slipping block and lower mold body groove body wall face extrusion metal pipe namely form second bulge loop at metal tube.
The utility model metal tube termination double convex ring one-time-shaped mould is simple in structure, reasonable in design, but time processing forms the double convex ring of metal tube termination, saves operation, improves working (machining) efficiency.
Description of drawings:
Fig. 1 is the organigram of metal tube;
Fig. 2 is the utility model master pseudosection;
Fig. 3 is the utility model top plan view (removal upper die body);
Fig. 4 is the schematic diagram that side form body extrusion metal pipe end forms the first bulge loop;
Fig. 5 is the schematic diagram that side form body extrusion metal pipe end forms the second bulge loop.
The specific embodiment:
The utility model metal tube termination double convex ring one-time-shaped mould, comprise upper and lower die body 1,2 and side form body 3, be provided with the slipping block 5 of slippage in the groove body in the groove body 4 of described upper and lower die body sidepiece, upper and lower die body 1,2 and slipping block 5 be provided with the conduit 6 that compresses metal tube, described side form body side surface is provided with depression 7.
In order to be conducive to slipping block 5 returns, be provided with spring 8 between above-mentioned slipping block and the groove body.
Above-mentioned depression is the rounded depression in cross section, is provided with taper platform 9 in concave bottom, and this taper platform 9 is conducive to form the first bulge loop 11.
The operation principle of the utility model metal tube termination double convex ring one-time-shaped mould, metal tube to be processed is placed on the lower mold body, metal tube end slightly has one section to be exposed at outside the lower mold body, upper die body presses down, conduit is fixed metal tube, the side form body action, advance toward the metal tube termination from side direction, this depression is namely pushed and is exposed at the outer metal tube end of lower mold body (namely form first bulge loop at metal tube end this moment), the side form body continues to advance, squeeze and push away slipping block, slipping block and lower mold body groove body wall face extrusion metal pipe namely form second bulge loop 12 at metal tube.
The utility model metal tube termination double convex ring one-time-shaped mould is simple in structure, reasonable in design, but time processing forms the double convex ring of metal tube termination, saves operation, improves working (machining) efficiency.
