CN202556633U - Non-magnitude eccentric diameter-transformed connector die - Google Patents

Abstract

The utility model relates to a non-magnitude eccentric diameter-transformed connector die comprising a core die main body, wherein the core die main body is formed by connecting a small-bore core die, a big-bore core die and a transitional core die through an adjusting screw rod. The axis of the big-bore core die and that of the small-bore core die are not on the same line. A core die can be replaced arbitrarily according to the required size of a tube connector, and cost of the eccentric diameter-transformed connector die is reduced. An axial section of the transitional core die is in right trapezoid shape. The bottom of the big-bore core die, the bottom of the small-bore core die and the right-angle edge bottom of the transitional core die are on the same horizontal line. Therefore, the ponding problem of the rear end of a pipeline is well solved. A stopping annular groove is formed on the connecting portion of the small-bore core die and the transitional core die, and therefore the small-bore pipeline is inserted in place immediately, conveniently and rapidly.

Description

The eccentric reducer union mould of no magnitude

Technical field

The utility model relates to the attaching parts of water supply and sewerage pipeline, the processing and fabricating mould of particularly long-range buried pipe and the jointing of making somebody a mere figurehead the different tube diameters that pipeline is set.

Background technology

In recent years, along with the needs of urbanization and industrialization development, all want every year newly-built with transform a large amount of water factories and sewage treatment plant, correspondingly also to lay a large amount of pipelines.From the water supply and sewage work instance analysis, every increase 10000m aspect feedwater ³The water supply capacity of/d needs newly-built feedwater piping 13-15km; Aspect sewage, every increase 10000m ³The disposal ability of/d needs to build sewage conduct 9-11km.In water supply and sewage work, the pipeline input accounts for 60% of whole construction costs, thus the application of pipeline and pipe technology and the development nature receive much attention.

Water supply and sewerage pipeline adopts concentric joint or eccentric joint usually when the pipeline of different tube diameters connects, the processing and fabricating of joint is fairly simple with one heart, but practicality is relatively poor; Pressure loss in piping is bigger; The pipeline end is prone to cause anhydrous or few water, and eccentric joint is better low to have solved this problem, but the processing and fabricating of eccentric joint is relatively more difficult; Especially mould, cost is higher.

The utility model content

The purpose of the utility model is to provide a kind of mould that can reduce eccentric reducer union cost of manufacture of no magnitude and manufacture difficulty.

The technical scheme that realizes the utility model purpose is: the utlity model has the core main body; Said core main body is formed by connecting small-bore core, heavy caliber core and transition core.Said heavy caliber core is fixedly connected with the transition core through adjusting screw(rod).Said small-bore core is fixedly connected with the transition core through the stop bit adjusting screw(rod).The axis of heavy caliber core and small-bore core is not point-blank.

The junction of above-mentioned small-bore core and transition core forms an annular stop bit annular groove.

The axial section of above-mentioned transition core is a right-angled trapezium.The right-angle side bottom of the heavy caliber core bottom of core main body, small-bore core bottom and transition core is on same horizontal line.

The utlity model has positive effect: the suit combination that (1) the utility model is made up of through adjusting screw(rod) large and small core and excessive core; So can come arbitrarily to change core according to the pipe joint needs, reduce the die cost of eccentric reducer union; The interleaved plan of small-bore pipeline when (2) the utility model has been considered to install through being provided with of position-arresting ring; (3) the eccentric reducer union mould of the described no magnitude of the utility model so the processing thickness of its product can be selected arbitrarily by the engineering design requirement, can't receive the restriction of grinding tool because of belonging to formpiston.

Description of drawings

For the content that makes the utility model is expressly understood more easily,, the utility model is done further detailed explanation, wherein below according to specific embodiment and combine accompanying drawing

Fig. 1 is the cutaway view of the utility model;

The specific embodiment

See Fig. 1, the utlity model has core main body 1; Said core main body 1 is formed by connecting small-bore core 13, heavy caliber core 11 and transition core 12.Said heavy caliber core 11 is fixedly connected with transition core 12 through adjusting screw(rod) 2.Said small-bore core 13 is fixedly connected with transition core 12 through stop bit adjusting screw(rod) 3.The axis of heavy caliber core 11 and small-bore core 13 is not point-blank.The utility model can arbitrarily change core according to the pipe joint required size, has reduced the die cost of eccentric reducer union.The axial section of said transition core 12 is a right-angled trapezium, the right-angle side of heavy caliber core 11 bottoms of core main body 1, small-bore core 13 bottoms and transition core 12 bottom on same horizontal line, thereby well solved the ponding problem of pipe end.And the junction of small-bore core 13 and transition core 12 forms an annular stop bit annular groove 4, makes small-bore pipeline can put in place immediately when inserting, and is fast convenient.

Above-described specific embodiment; Purpose, technical scheme and beneficial effect to the utility model have carried out further explain, it should be understood that the above is merely the specific embodiment of the utility model; Be not limited to the utility model; All within the spirit and principle of the utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
